Description

Data service processing method and device

The present invention relates to mobile communication technologies, and in particular, to a data service processing method and device.

Background technique

After the user accesses the wireless access network and the packet core network, a data service channel is established, and data services can be performed.

Currently, information in the user's data service is transmitted in the form of an Internet Protocol (IP) packet. The IP packets sent by the user (ie, the uplink IP packets) are used in a specific manner in the wireless access network and the core network, such as the General Packet Radio Service (GPRS) tunneling protocol (GPRS) protocol (GTP) user. The face (GTP-U) protocol, encapsulated as a payload, also encapsulates the IP packet into a GTP-U packet for transmission. After the encapsulated IP packet passes through the data gateway of the mobile network, for example, it may be a packet data network gateway (PGW) or a gateway GPRS support node (gateway GRPS support node), and the data gateway is decapsulated to the original IP of the user. The message mode is sent to an external data network, such as the Internet (the Internet packet sent by the external data network to the user (ie, the downlink IP packet), first arrives at the data gateway of the mobile network, and the data gateway loads the IP packet of the external data network. Encapsulation, and then the encapsulated IP packet arrives at the base station device after being transmitted by the core network, and the base station device sends the IP packet to the user equipment in the wireless air interface. Thus, the data service interaction between the user and the external data network is realized. In the process of transmitting IP packets, related devices of the core network will generate CDRs to record The accumulated value of the user's upstream and downstream IP packet sizes is passed as a charging record, and the user is charged for the mobile network data service fee. However, in the current billing system, the billing of data services is not fine enough.

The present invention will be further described in detail with reference to the accompanying drawings, in which FIG. An embodiment. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention. FIG. 1 is a flowchart of a method for processing a data service according to an embodiment of the present invention. The method shown in this embodiment is the processing flow of the downstream network node device of the data gateway, and the downstream network node device may be an SGSN, an SGW, or the like. The processing procedure includes: Step 11: The network node receives the downlink data sent by the data gateway, and the ID of the service to which the downlink data belongs. The network node is a downstream network node device of the data gateway. For example, the downstream network node device of the data gateway receives the first GTP-U packet sent by the data gateway. The payload of the first GTP-U packet is an IP packet, and the header of the first GTP-U packet contains an identifier of a service of the IP packet. The network node parses the received first GTP-U packet, and obtains the identifier of the service of the IP packet and the IP packet. If the SGW parses the first GTP-U packet, the identifier of the service of the payload IP packet of the first GTP-U packet is obtained.

The identification of the service of the data gateway, the first GTP-U packet, and the IP packet is shown in the description in the embodiment shown in FIG.

Step 12: The network node forwards the downlink data received in step 11 to the user equipment by using the base station device.

For the LTE network, the network node may encapsulate the parsed IP packet into a second GTP-U packet, and then send the second GTP-U packet to the downstream network node. Wherein, the second GTP-U package can be a traditional GTP-U package;

For example, the SGW forwards the IP packet to the eNodeB, and the IP packet needs to be encapsulated into a GTP-U packet, and the GTP-U packet may not include the identifier of the service of the IP packet.

For the UMTS network, the network node can re-encapsulate the parsed IP packet into a GTP-U packet, and then send the GTP-U packet to the downstream network node. For example, the SGSN sends a GTP-U packet to the RNC. For the GSM network, the network node can encapsulate the parsed IP packet into a BSSGP packet, and then send the BSSGP packet to the downstream network node. For example, the SGSN encapsulates the parsed IP packet into a BSSGP packet and sends the BSSGP packet to the BSC/PCU. Step 13: The network node obtains, according to the forwarding result, the traffic information of the downlink data that is successfully forwarded by the service, based on the identifier of the service. For example, the network node generates the identifier of the service of the IP packet into the bill only when the IP packet is successfully forwarded. That is, when an IP packet is discarded or the IP packet is discarded, the forwarding traffic of the service to which the IP packet belongs in the CDR does not include the traffic of the IP packet, and only when the IP is successfully forwarded, the IP packet The forwarding traffic of the belonging service will contain the traffic of the IP packet.

The generation of the bill can be based on time or based on forwarding traffic. For example, when the downstream network node device of the data gateway forwards for more than one hour, the downstream network node device generates a bill, or is a downstream network node device of the data gateway. When the forwarding traffic exceeds 100 Mbytes, the downstream network node device generates a bill. After the identifier of the service of the IP packet is generated in the CDR, the traffic information of each service is added to the CDR according to the traditional CDR, so that the forwarding traffic of each service can be accurately reduced and the finer billing can be realized. , can also make billing more accurate. For example, the network node, according to the forwarding result, obtains the traffic information of the downlink data that is successfully forwarded according to the service, and may include: the network node locally forwarding the result according to the network node. And obtaining, according to the identifier of the service, traffic information of the downlink data that is successfully forwarded by the network node corresponding to the service, where the traffic information of the downlink data that is successfully forwarded by the network node corresponding to the service is used as the The traffic information of the downlink data that is successfully forwarded by the service. For example, the network node, according to the forwarding result, obtains the traffic information of the downlink data that is successfully forwarded according to the service, and may include: the network node locally forwarding the result according to the network node. As a result of the failure of the forwarding of the base station device, based on the identifier of the service, the traffic information of the downlink data successfully forwarded by the service is obtained.

Further, the processing method of the data service provided by the embodiment of the present invention may further include: the network node sending the identifier of the service to the base station device, where the network node carries the downlink data in the same packet when forwarding the line data. The identity of the business to which it belongs;

Receiving, by the network node, a result of the forwarding failure of the base station device sent by the base station device, where the result of the forwarding failure of the base station device includes: the flow rate information of the downlink data that the base station device fails to forward and the identifier of the service; Correspondingly, the network node obtains, according to the forwarding result of the network node and the forwarding failure of the base station device, the traffic information of the downlink data that is successfully forwarded by the service, according to the identifier of the service, Includes:

The network node obtains, according to the forwarding result of the network node, the traffic information of the downlink data successfully forwarded by the network node corresponding to the service, according to the identifier of the service; the network node corresponds to the service according to the service The network node forwards the traffic information of the successfully downlink data and the traffic information of the downlink data that the base station device forwards, and obtains the traffic information of the downlink data that is successfully forwarded by the service based on the identifier of the service. If the base station device does not successfully forward the downlink data, the radio access bearer (RAB) allocates a response message, and the RAB allocation response message carries the traffic information of the unsuccessfully forwarded IP packet and the identifier of the service to which it belongs. The RAB Assignment Response message belongs to a message in the RAB allocation process. The RAB allocation process is used to establish or release a wireless data transmission connection, including: The SGSN sends an RAB allocation request to the RNC, and the RNC returns a RAB allocation response message to the SGSN after establishing or releasing the wireless data transmission connection. In the embodiment of the present invention, when the RAB allocation process releases the wireless data transmission connection, the RNC carries the downlink traffic information that is not successfully sent in the RAB allocation response message sent to the SGSN, so as to implement a more accurate traffic calculation. fee. The extended RAB allocation response message is shown in the following table:

The traffic of the downlink data service type 2 that is not successfully transmitted is such that the network node can deduct from the identifier of the recorded service that the base station device has not successfully forwarded The traffic of the data stream can further improve the accuracy of the downlink data forwarding traffic and improve the accuracy of the charging. For example, the network node obtains, according to the forwarding result, the traffic information of the downlink data that is successfully forwarded by the service, based on the identifier of the service, and may include: the network node successfully forwarding according to the base station device As a result, based on the identifier of the service, the traffic information of the downlink data successfully forwarded by the service is obtained.

Correspondingly, the method for processing the data service provided by the embodiment of the present invention may further include: the network node sending the identifier of the service to the base station device; and the network node receiving the base station device sent by the base station device As a result of the successful forwarding, the result of the successful forwarding of the base station device includes: the flow rate information of the downlink data successfully transmitted by the base station device and the identifier of the service; and the network node according to the successful forwarding result of the base station device, And obtaining, according to the identifier of the service, the traffic information of the downlink data that is successfully forwarded by the service, including:

And the network node obtains the traffic information of the downlink data that is successfully forwarded according to the service, according to the traffic information of the downlink data that is successfully forwarded by the base station device. The method for processing the data service provided by the embodiment receives the identifier of the service to which the downlink data is sent by the data gateway, and obtains the traffic information of the downlink data successfully forwarded by the service according to the forwarding result of the downlink data and the identifier of the received service. Can meet more refined billing needs. At the same time, the downstream network node of the data gateway can obtain the traffic forwarding information of each service, so that more accurate charging can be performed for each service according to the forwarding situation of different network nodes. If the downstream network node device of the data gateway successfully forwards the IP packet, the identifier of the service of the IP packet is generated into the CDR, so that the traffic forwarding information of each service can be recorded in the generated CDR, and the forwarding traffic is implemented. Accurate deduction to achieve accurate billing purposes.

FIG. 2 is a flowchart of a method for processing a data service according to an embodiment of the present invention. The method shown in this embodiment is the processing flow of the data gateway, and the data gateway may be a GGSN, a PGW, etc., and the processing flow includes:

Step 21: The data gateway receives downlink data. For example, the PGW receives a message encapsulated with an IP packet from the Internet (Internet). The packet of the IP packet may be the downlink data sent by the external server. Messages, etc. Step 22: The data gateway acquires an identifier of a service to which the downlink data belongs. For example, the data gateway obtains the identifier of the service to which the downlink data belongs by using the deep packet inspection (DPI) technology, and may also obtain the identifier of the service to which the downlink data belongs from other network elements having the DPI function.

Step 23: The data gateway sends the downlink data and the identifier of the service to the downstream network node, so that the downstream network node forwards the downlink data to the user equipment, and obtains, according to the forwarding result, the identifier based on the service. The traffic information of the downlink data that is successfully forwarded by the service. For example, the data gateway may send the downlink data and the identifier of the service to the downstream network node by encapsulating the downlink data and the identifier of the service in a tunnel message. For example, the data gateway may encapsulate the IP packet received in the foregoing step 21 into a first GTP-U packet, where the header of the first GTP-U packet contains the identifier of the service of the IP packet. The payload in the first GTP-U packet is an IP packet, and the first GTP-U packet may be extended on the basis of the traditional GTP-U packet, and the identifier of the service carrying the IP packet is added in the extension field. The identifier of the service of the IP packet contains at least the service type and traffic information of the IP packet.

Then, the data gateway sends the encapsulated first GTP-U packet to the downstream network node device. The downstream network node device may be an SGSN, an SGW, or the like. In the data service processing method provided by the embodiment, the data gateway sends the downlink data from the external network and the identifier of the service to which the downlink data belongs to the downstream network node device, so that the downstream network node device can obtain the service to which the downlink data belongs. The identification of the downstream network node device of the data gateway can also obtain the traffic forwarding information of the specific service, thereby obtaining the traffic information of the downlink data based on the service, enabling more refined charging and realizing each service forwarding. Accurate deduction of traffic for more accurate billing purposes. FIG. 3 is a flowchart of a method for processing a data service according to an embodiment of the present invention. The method shown in this embodiment is the processing flow of the downstream network node device (ie, the base station device) of the first downstream network element, and the base station device may be an eNodeB, an RNC, and the like. The processing procedure includes: Step 31: The base station device receives the upstream network node. The downlink data sent and the identifier of the service to which the downlink data belongs. For example, the base station device receives the first GTP-U packet sent by the downstream network node device of the data gateway, where the payload of the first GTP-U packet is an IP packet, and the header of the first GTP-U packet includes the IP packet. The identity of the business. The identifiers of the downstream network node device, the first GTP-U packet, and the service of the data gateway are shown in the description in the embodiment shown in FIG.

The identifier of the service of the IP packet is used to identify the service corresponding to the IP packet.

Step 32: The base station device forwards the downlink data to the user equipment. For example, the base station device receives the first GTP-U packet, parses the first GTP-U packet, obtains the identifier of the IP packet and the service of the IP packet, and then sends the IP packet to the user equipment through the air interface protocol. For example, the RNC parses the first GTP-U packet, obtains the identifier of the service of the payload of the first GTP-U packet, and sends the IP packet to the user equipment by using an air interface protocol. Step 33: The base station device sends a forwarding result of the base station device to the upstream network node, so that the upstream network node obtains the service corresponding according to the forwarding result of the base station device according to the identifier of the service. The forwarding information of the downlink data is successfully forwarded; the forwarding result of the base station device includes one of the identifier of the service and one of the following traffic information: the traffic information of the downlink data that the base station device forwards successfully and the forwarding failure of the base station device Traffic information for downstream data.

For example, when the forwarding is successful, the base station device sends an RAB allocation response message to the upstream node, where the RAB allocation response message carries the traffic information of the successfully forwarded downlink data and the identifier of the service to which the successfully forwarded downlink data belongs, thereby The upstream node forwards the traffic information of the succeeding downlink data at the base station device, so that the upstream node acquires the traffic information of the downlink data successfully forwarded by the service. For example, if the forwarding fails, the base station device sends an RAB allocation response message to the downstream network node device of the data gateway, where the RAB allocation response message carries the identifier of the service of the unsuccessfully forwarded IP packet. For example, when the RAB (Radio Link) between the SGSN and the RNC is released, the RNC sends an RAB Assignment Response message to the SGSN, where the RAB Assignment Response message carries the traffic information of the unsuccessfully forwarded IP packet and the identifier of the service to which it belongs, for example, The extension field in the RAB allocation response message adds the traffic information of the IP packet that is not successfully forwarded and the identifier of the service to which the service belongs. If the RNC successfully forwards all the IP packets, the value of the extended field is 0. Among them, RAB distribution The message should be as detailed in the description of the embodiment shown in FIG.

If the RNC has an IP packet that has not been successfully forwarded before the RAB between the SGSN and the RNC is released, the RAB allocation response message carries the traffic information of all the IP packets that are not successfully forwarded by the RNC and the identifier of the service to which it belongs, generally by IP packet. Service type to record traffic that was not successfully forwarded, such as:

When the IP packet in the first GTP-U packet received by the base station device is not successfully forwarded, the traffic of the IP packet will also be included in the traffic of the corresponding service. If the service type of the IP packet is RG1, then the traffic of the IP packet is included in the X megabyte. In the data service processing method provided by the embodiment, the base station device receives the downlink data and the identifier of the service to which the downlink data belongs, and the unsuccessfully forwarded downlink data carried in the RAB allocation response message sent to the upstream network node device The traffic information of the failed data packet enables the downstream network node device of the data gateway to accurately reduce the traffic of the service that has not been successfully forwarded, thereby realizing accurate charging of the service.

FIG. 4 is a schematic diagram of a data service traffic recording method according to another embodiment of the present invention. The embodiment is similar to the foregoing embodiment, except that the application scenario of the embodiment is an LTE network, and a service data list (list@fServiceData) field is added to the SGW bill to fill the traffic information of each service.

In an LTE network, the SGW and the PGW are respectively network elements for forwarding user IP packets in the core network. In the core network, the user IP packet is encapsulated by the GTP-U protocol, that is, the IP packet is encapsulated into a GTP-U packet, and the header of the GTP-U packet needs to be extended, such as a Rate Group (RG) field, to be used. The identity of the delivery service, that is, the identity of the service that adds the GTP-U packet payload IP packet in the RG field. The following is an example of the process of transmitting IP packets: The process of collecting traffic statistics for data services includes:

Step 41: After receiving the downlink IP packet of the user, the PGW obtains the identifier of the service of the downlink IP packet, and encapsulates the downlink IP packet into a GTP-U packet. For example, after receiving the downlink IP packet, the PGW determines the characteristics of the IP packet, such as the protocol/port number (such as TCP port 80 for HTTP application), the service characteristics of the IP packet content (such as the HTTP domain name), etc. The service identifier of the service type can also obtain the service identifier of the packet through the deep packet parsing technology. The identifier of the service of an IP packet can be used to identify the service type, traffic, etc. of the IP packet. The information in this embodiment of the present invention is not limited thereto.

In the header of the GTP-U encapsulating this IP packet, an RG field is added, and the RG field is filled with the identity of the service. The PGW forwards the GTP-U packet to the downstream network node device SGW according to a conventional procedure.

The PGW generates a bill based on the forwarding result. For example, as long as the traffic forwarded by the PGW reaches a certain amount, for example, 4 Mbytes, the PGW can generate an intermediate CDR to record the forwarded traffic, avoiding the user's long-term use of the service without generating bills, and avoiding huge traffic. The risk of CDRs.

The CDRs generated by the PGW include not only the total uplink and downlink traffic of the user, but also the uplink and downlink traffic of each service of the user. For example, the following order is generated:

• listOfTrafficVolumes (Uplink=8MByte, Downlink=14MByte) 总 The total upstream traffic generated by the user is 8 Mbytes, and the downstream traffic is 14 Mbytes;

• l istOfServiceData=RGl (HTTP) upl ink=4MByte, downlink=6MByte; RG 2 (Video) uplink=lMByte, downlink=3Mbyte; RG3 (IM) uplink=3MByte, do wnlink=5Mbyte〃The user RG1 service has been generated The upstream traffic is 4 Mbytes, and the downstream traffic is 6 Mbytes. The upstream traffic generated by the RG2 service is 1 Mbyte, and the downstream traffic is 3 Mbytes. The upstream traffic generated by the RG3 service is 3 Mbytes, and the downstream traffic is 5 Mbytes. Section. Step 42: After receiving the GTP-U packet (that is, the first GTP-U packet), the SGW parses the identifier of the service of the IP packet and the GTP-U header. If the SGW forwards the IP packet to the eNodeB, it encapsulates the IP packet as a GTP-U packet and sends it to the eNodeB. The SGW may not send the identity of the service to the eNodeB. When the SGW sends an IP packet to the eNB, the identifier of the service of the GTP-U packet header may be removed, that is, the SGW may encapsulate the IP packet to be sent to the eNodeB by using the normal GTP-U packet of the 3GPP standard. The SGW can also send the identifier of the service to the eNodeB, so that the eNodeB reports the result of forwarding it to the user equipment. An exemplary header of the GTP-U packet that can be sent to the eNodeB includes the identity of the service to which the IP packet of the payload belongs.

For example, as long as the traffic forwarded by the SGW reaches a certain amount, for example, 4 Mbytes, the SGW can generate an intermediate CDR to record the forwarded traffic, so as to avoid the user from using the service for a long time without generating a CDR. The risk of huge flow bills.

Exemplarily, the SGW generates the total uplink and downlink traffic generated by the user and the uplink and downlink flows generated by the user services, regardless of whether the GGW-U packet is successfully sent to the eNodeB. The amount of traffic information is recorded in the extended listOfServiceData field. The uplink and downlink traffic generated by each user of the user is obtained according to the GTP-U packet forwarding result and the service identifier of the GTP-U packet header.

For example, if the IP packet is successfully forwarded, the SGW records the identity of the service of the IP packet of the user in the system, and finally records in the listOfServiceData field of the SGW CDR bill extension that the SGW successfully forwards the service corresponding to the user. Traffic, such as:

• l istOfTrafficVolumes (Upl ink=8MByte, Downlink=14MByte) 总 The total upstream traffic generated by this user is 8 Mbytes, and the downstream traffic is 14 Mbytes;

• listOfServiceData=RGl (HTTP) upl ink=4MByte, downlink=6MByte; RG2 (Video) uplink=lMByte, downlink=3Mbyte; RG3 (IM) uplink=3MByte, downlink=5Mbyte〃 The upstream traffic generated by the user RG1 service is 4 Mbytes, the downstream traffic is 6 Mbytes, the upstream traffic generated by the RG2 service is 1 Mbyte, and the downstream traffic is 3 Mbytes. The upstream traffic generated by the RG3 service is 3 Mbytes, and the downstream traffic is 5 Mbytes.

In the SGW CDR, the uplink and downlink traffic of the user and the uplink and downlink traffic of each service are consistent with the uplink and downlink traffic of the user in the PGW bill and the uplink and downlink traffic of each service.

If the SGW fails to discard the GTP-U packet or forwards the GTP-U packet, the CDR generated by the SGW still contains the traffic information of each service actually forwarded. For example, the resulting bill is as follows:

• listOfTrafficVolumes (Uplink=8MByte, Downl ink=12MByte) 总 The total upstream traffic generated by the user is 8 Mbytes, and the downstream traffic is 12 Mbytes;

•l istOfServiceData=RGl (HTTP) upl ink=4MByte, downl ink=6MByte; RG

2 (Video) uplink=lMByte, downlink=2Mbyte; RG3 (IM) uplink=3MByte, do wnlink=4Mbyte〃 The upstream traffic generated by the user RG1 service is 4M bytes, the downstream traffic is 6M bytes, and the RG2 service has been generated. The upstream traffic is 1 Mbyte, and the downstream traffic is 2 Mbytes. The upstream traffic generated by the RG3 service is 3 Mbytes, and the downstream traffic is 4 Mbytes.

The traffic generated by each service can be obtained from the CDRs generated by the SGW. For example, compared with the CDRs generated by the PGW, the downlink traffic of the RG2 service and the downlink traffic of the RG3 service are respectively lost by 1 Mbyte, so that the traffic can be accurately obtained. The nuclear flow is reduced, and the billing error is avoided. FIG. 5 is a schematic diagram of a data service traffic recording method according to another embodiment of the present invention. Ben The embodiment is similar to the foregoing embodiment, except that the application scenario of the embodiment is a UMTS network, and a service data list (l istOfServiceData) field is added to the CDR of the SGSN, which is used to fill traffic information of each service, and is extended. The Radio Access Bearer (RAB) is a RAB assignment response message. In the UMTS network, the SGSN and the GGSN are respectively used by the core network to forward user IP packets. In the core network, the user IP packet is encapsulated by the GTP-U protocol, that is, the IP packet is encapsulated into a GTP-U packet, and the header of the GTP-U packet needs to be extended, for example, the RG field is added to transmit the service identifier. As an example of the following process of delivering IP packets, the traffic statistics process for data service charging includes:

Step 51: The GGSN receives the downlink IP packet, and after analyzing the downlink IP packet by using the DPI technology, obtains the identifier of the service of the downlink IP packet. After that, the GGSN encapsulates the IP packet into a GTP-U packet, and the GTP-U packet includes the identifier of the service, and then the GTP-U packet can be forwarded to the first downstream network node device SGSN according to a conventional process. For details of the service analysis, see the description of step 41 above. For example, when the GGSN encapsulates the downlink IP packet into a GTP-U packet, the RG field is added to the GTP-U packet header, and the RG field is filled with the identifier of the obtained downlink IP packet service. After the GGSN completes the forwarding of the GTP-U packet, as long as the GGSN forwards a certain amount of traffic, for example, 4 Mbytes, the GGSN can generate an intermediate CDR to record the forwarded traffic, so as to prevent the user from using the service for a long time without generating In the case of bills, the risk of avoiding huge flow bills.

The GGSN generates a bill, such as:

• list0fTrafficVolumes (Uplink=8MByte, Downl ink=14MByte) 总 The total upstream traffic generated by the user is 8 Mbytes, and the downstream traffic is 14 Mbytes;

• l istOfServiceData=RGl (HTTP) upl ink=4MByte, downlink=6MByte; RG 2 (Video) uplink=lMByte, downlink=3Mbyte; RG3 (IM) uplink=3MByte, do wnlink=5Mbyte〃The user RGl service has been generated The upstream traffic is 4 Mbytes, the downstream traffic is 6 Mbytes, the upstream traffic generated by the RG2 service is 1 Mbyte, and the downstream traffic is 3 Mbytes. The upstream traffic generated by the RG3 service is 3 Mbytes, and the downstream traffic is 5 Mbytes. Section. Step 52: After receiving the GTP-U packet, the SGSN parses the identifier of the service of the IP packet in the payload from the header of the GTP-U packet, and encapsulates the IP packet into a GTP-U packet, and then forwards the packet to the RNC.

The IP packet is also transmitted between the SGSN and the RNC through GTP-U, and the head of the GTP-U packet is still The identity of the service that contains the IP packet.

When the SGSN forwards a certain amount of traffic, for example, 4 Mbytes, the SGSN can generate an intermediate CDR to record the forwarded traffic. This prevents users from using the service for a long time without generating bills, and avoids huge traffic bills. risks of.

If the IP packet is successfully forwarded to the RNC, the SGSN records the service identifier of the IP packet of the user in the system, and finally records the traffic successfully forwarded by the SGSN to each service of the SGSN in the listOfServiceData field of the CDR CDR bill extension. , Such as:

· listOfServiceData=RGl (HTTP) upl ink=4MByte, downlink=6MByte;

RG2 (Video) uplink=lMByte, downlink=3Mbyte; RG3 (IM) uplink=3MByte, downlink=5Mbyte〃 The upstream traffic generated by the user RG1 service is 4M bytes, and the downstream traffic is 6M bytes. The RG2 service has been generated. The upstream traffic is 1 Mbyte, and the downstream traffic is 3 Mbytes. The upstream traffic generated by the RG3 service is 3 Mbytes, and the downstream traffic is 5 Mbytes.

In the SGSN CDR, the uplink and downlink traffic of the user and the uplink and downlink traffic of each service are consistent with the uplink and downlink traffic of the user in the GGSN CDR and the uplink and downlink traffic of each service. After that, go to step 53.

If the SGSN fails to discard the GTP-U packet or forwards the GTP-U packet, the CDRs generated by the SGSN still contain the traffic information of each service actually forwarded. For example, the resulting bill is as follows:

• l istOfServiceData=RGl (HTTP) upl ink=4MByte, downlink=6MByte; RG 2 (Video) uplink=lMByte, downlink=2Mbyte; RG3 (IM) uplink=3MByte, do wnlink=4Mbyte〃The user RGl service has been generated The upstream traffic is 4 Mbytes, the downstream traffic is 6 Mbytes, the upstream traffic generated by the RG2 service is 1 Mbyte, and the downstream traffic is 2 Mbytes. The upstream traffic generated by the RG3 service is 3 Mbytes, and the downstream traffic is 4 Mbytes. Section. The traffic generated by the SGSN can be obtained from the CDRs generated by the SGSN. For example, compared with the CDRs generated by the GGSN, the downstream traffic of the RG2 service and the downstream traffic of the RG3 service are respectively lost by 1 Mbyte. For the billing of each service, it is refined Billing. In addition, according to the CDR between the SGSN and the GGSN, the traffic can be accurately reduced, the charging error is avoided, and the accuracy of the charging is improved.

Step 53: After receiving the GTP-U packet, the RNC parses the GTP-U header to obtain the identifier of the service of the IP packet. When the RAB (Radio Link) between the SGSN and the RNC is released, the RNC sends an RAB Assignment Response message to the SGSN. The RAB allocation response message carries the traffic information of the unsuccessfully forwarded IP packet and the identifier of the service to be forwarded, for example, an extension field in the RAB allocation response message, and adds the traffic information of the unsuccessfully forwarded IP packet and the service to which the service belongs in the extended field. Logo.

Exemplarily, after the RNC successfully forwards the IP packet in the GTP-U packet, the RNC system records the service identifier and traffic information of the IP packet of the user according to the identifier of the parsed service. When the RNC successfully forwards all the IP packets in the received GTP-U packet, the value of the extended field in the RAB allocation response message is 0. Exemplarily, when the RNC fails to forward the IP packet in the GTP-U packet, if the RNC fails to drop or forward, the RNC adds the traffic of the IP packet in the GTP-U packet in the extension field of the RAB allocation response message. Information and the identity of the business to which it belongs.

For example, the RAB allocation response message adds the traffic information of the IP packets that are not successfully forwarded by the RNC before the RAB release between the SGSN and the RNC, and the identifier of the service to which the service belongs. Generally, the traffic that is not successfully forwarded is recorded according to the service type of the IP packet, for example, :

Service RG1 X megabytes, service RG2 Y megabytes.

The RNC informs the SGSN of the traffic information of the IP packet that is not successfully sent to the terminal and the identity advertisement RAB assignment response message of the service to be used for correct deduction of the forwarding traffic of the SGSN side.

After receiving the RAB allocation response message returned by the RNC, the SGSN adds the traffic information of the unsuccessfully forwarded IP packet and the identity of the service to the generated CDR, and the SGSN deducts the corresponding traffic and service traffic to generate an end CDR.

When the forwarding traffic is decremented, the SGSN saves all the downlink traffic forwarded by the SGSN, so the unsuccessfully sent traffic in the RAB allocation response message is subtracted, and the successfully sent traffic is obtained. FIG. 6 is a schematic diagram of a data service traffic recording method according to another embodiment of the present invention. This embodiment is similar to the foregoing embodiment, except that the application scenario of the embodiment is a GSM network, and a service data list (l istOfServiceData) field is added to the CDR of the SGSN, which is used to fill in Charge traffic information for each business.

In the GSM network, the SGSN and the GGSN are the network elements used by the core network to forward user IP packets. In the core network, the user IP packet is encapsulated by the GTP-U protocol, that is, the IP packet is encapsulated into a GTP-U packet, and the header of the GTP-U packet needs to be extended, for example, an RG field is added to transmit the service identifier. The following is an example of the process of transmitting the IP packet. The process of collecting the traffic of the data packet includes: Step 61: After receiving the downlink IP packet of the user, the GGSN obtains the identifier of the service of the downlink IP packet by using the DPI. The downlink IP packet is encapsulated into a GTP-U packet. Moreover, the GGSN forwards the GTP-U packet to the downstream network node device SGSN according to a conventional procedure. For details, refer to the description in step 41 above. The identifier of the service of the IP packet contains at least information such as the service type and traffic of the IP packet.

In the header of the GTP-U encapsulating this IP packet, an RG field is added, and the RG field is filled with the identity of the service.

The GGSN generates a bill based on the forwarding result. For example, as long as the GGSN forwards a certain amount of traffic, for example, 4 Mbytes, the GGSN can generate an intermediate CDR to record the forwarded traffic. This prevents users from using the service for a long time without generating bills, and avoids huge traffic. The risk of CDRs.

The CDRs generated by the GGSN contain not only the total uplink and downlink traffic of the user but also the uplink and downlink traffic of each service. For example, the following order is generated:

• l istOfServiceData=RGl (HTTP) upl ink=4MByte, downlink=6MByte; RG 2 (Video) uplink=lMByte, downlink=3Mbyte; RG3 (IM) uplink=3MByte, do wnlink=5Mbyte〃The user RGl service has been generated The upstream traffic is 4 Mbytes, the downstream traffic is 6 Mbytes, the upstream traffic generated by the RG2 service is 1 Mbyte, and the downstream traffic is 3 Mbytes. The upstream traffic generated by the RG3 service is 3 Mbytes, and the downstream traffic is 5 Mbytes. Section. Step 62: After receiving the GTP-U packet, the SGSN parses the IP packet and the identifier of the service of the IP packet, and because the SGSN and the BSC/PCU encapsulate the user IP packet by using the BSSGP manner, the SGSN will The parsed IP packet is encapsulated into a BSSGP packet and forwarded to the base station device.

For example, the SGSN does not need to send the identifier of the service to the BSC/PCU, that is, the identifier of the service that does not carry the IP packet in the BSSGP packet, because the BSC/PCU does not generate the CDR and does not notify the core network of the traffic that is not successfully sent. .

Exemplarily, the SGSN may also send an identifier of the service to the BSC/PCU, so that the BSC/PCU reports the forwarding result.

As long as the SGSN forwards a certain amount of traffic, for example, 4 Mbytes, the SGSN can generate an intermediate CDR to record the forwarded traffic. This prevents users from using the service for a long time without generating bills, and avoids huge traffic bills. risks of.

The CDRs generated by the SGSN include the total uplink and downlink traffic generated by the user and the uplink and downlink traffic generated by the services of the user. The traffic information is recorded in the extended listOfServiceData field. The uplink and downlink traffic generated by each user of the user is obtained according to the GTP-U packet forwarding result and the service identifier of the GTP-U packet header.

If the BSSGP packet is successfully forwarded, the SGSN records the service identifier of the IP packet in the BSSGP packet in the system, and finally records the traffic successfully forwarded by the SGSN to the service of the user in the istOfServiceData field of the CDR CDR CDR extension, such as :

In the SGSN CDR, the uplink and downlink traffic of the user and the uplink and downlink traffic of each service are consistent with the uplink and downlink traffic of the user in the GGSN CDR and the uplink and downlink traffic of each service.

If the SGSN fails to discard the GTP-U packet or forwards the GTP-U packet, the CDRs generated by the SGSN still contain traffic information of each service. For example, the resulting bill is as follows:

• l istOfTrafficVolumes (Upl ink=8MByte, Downlink=12MByte) The total upstream traffic generated by the user is 8 Mbytes, and the downstream traffic is 12 Mbytes;

• l istOfServiceData=RGl (HTTP) upl ink=4MByte, downlink=6MByte; RG 2 (Video) uplink=lMByte, downlink=2Mbyte; RG3 (IM) uplink=3MByte, do wnlink=4Mbyte〃The user RGl service has been generated The upstream traffic is 4 Mbytes, the downstream traffic is 6 Mbytes, the upstream traffic generated by the RG2 service is 1 Mbyte, and the downstream traffic is 2 Mbytes. The upstream traffic generated by the RG3 service is 3 Mbytes, and the downstream traffic is 4 Mbytes. Section.

The traffic generated by the SGSN can be obtained from the CDRs generated by the SGSN. For example, compared with the CDRs generated by the GGSN, the downstream traffic of the RG2 service and the downstream traffic of the RG3 service are respectively lost by 1 Mbyte, thereby accurately The forwarding traffic is reduced, and the charging error is avoided. In this embodiment, the SGSN finally extends the listOfServiceData field in the SGSN SCDR bill according to the identifier of the solution service recorded in the RG field of the GTP-U header, and records the traffic of the SGSN to the user and the corresponding successfully forwarded traffic. Service-based billing meets the need for more granular billing. At the same time, the correct deduction of the service billing traffic in the case of core network element packet loss is achieved, and the accuracy of billing is improved.
