Abstract

The present invention relates to the field of communication, particularly to a method for locking gateway support node service of general packet radio service. Thus, the requirement of a mobile carrier of prohibiting a newly added user from being on-line can be satisfied. Not only can the service of an entire GGSN single plate be locked, but also the service for the newly added user to access a certain APN can be locked. Thereby, the practical operating state of a device on a network and the requirement of the mobile carrier can be considered more comprehensively. A GGSN judges whether the self GGSN is locked according to a lock token with respect to an activation request message from an SGSN in the method for locking gateway support node service of general packet radio service, or a configuration database is queried according to the APN corresponding to the activation request message so as to judge whether the APN is locked. If the APN is locked, an activation failure response is sent. Thus, the purpose of prohibiting the newly added user from being on-line is achieved.

Description

The locking means of gateway GPRS supporting node (GGSN) service

Technical field

The present invention relates to the communications field, when particularly mobile operator need forbid that new user connects, the lock-in techniques of gateway GPRS supporting node (GGSN) service.

Background technology

Universal mobile telecommunications system (Universal Mobile Telecommunications System, be called for short " UMTS ") be to adopt Wideband Code Division Multiple Access (WCDMA) (Wideband Code Division Multiple Access, abbreviation " WCDMA ") 3-G (Generation Three mobile communication system) of air interface technologies also calls the WCDMA communication system to the UMTS system usually.The UMTS system has adopted and the similar structure of second generation mobile communication system, comprises Radio Access Network (Radio Access Network is called for short " RAN ") and core network (Core Network is called for short " CN ").Wherein Radio Access Network is used to handle all and wireless function associated, and CN handles that all voice calls are connected with data in the UMTS system, and the exchange of realization and external network and routing function.CN is from being divided into circuit commutative field (CircuitSwitched Domain is called for short " CS ") and packet-switched domain (Packet Switched Domain is called for short " PS ") in logic.UMTS Terrestrial radio access network (UMTS Terrestrial Radio Access Network, be called for short " UTRAN "), CN and subscriber equipment (User Equipment, abbreviation " UE ") have constituted whole UMTS system together.

Fig. 1 is that UMTS network element of the prior art constitutes schematic diagram.

As shown in Figure 1, the UMTS network is made of 4 major parts, and subscriber equipment 10, UMTS Terrestrial radio access network 12, core network 14, external network 15 constitute.

Subscriber equipment 10 comprises user identity and differentiates module (USIM) 100, is exactly that the user identity of saying is usually differentiated module (Subscriber Identification Module is called for short " SIM ") card; Mobile device (Mobile Equipment is called for short " ME ") 102 is exactly the mobile phone of saying usually, and the two has constituted subscriber equipment (User Equipment is called for short " UE ") by Cu electric interfaces 101.

And the UMTS Terrestrial radio access network 12 among the figure is exactly an Access Network, and wherein base station 120, base station 121, base station 122, base station 123 are also referred to as Node B; Radio network controller (Radio NetworkController, be called for short " RNC ") 125 and radio network controller 127 are control and management functions of finishing the base station, link to each other by lur interface 126 between the two, the two with the base station between be connected by lub interface 124.The front end of UMTS Terrestrial radio access network 12 is connected by Uu interface 11 with subscriber equipment 10, and this interface is the radio open part, more complicated.Its rear end links to each other with core net 14 by Iu interface 13.

Parallel circuit switching domain (CS) and packet-switched domain (PS) are arranged in the core net 14.Mobile switching centre/visitor's location register (Mobile Switching Center/Visitor Location Register wherein, be called for short " MSC/VLR ") 140, GMSC (gateway mobile switching center) (Gateway Mobile Services SwitchingCenter, abbreviation " GMSC ") 143 belong to the CS territory, GPRS serving GPRS support node (Serving GPRS Support Node, be called for short " SGSN ") 141, gateway GPRS supporting node (GGSN) (GPRS Gateway Support Node, be called for short " GGSN ") 144, belong to the PS territory, attaching position register (Home Location Register is called for short " HLR ") 142 belongs to the total functional node in CS territory and PS territory.Mobile switching centre/visitor's location register 140 is finished the functions such as control, management, authentication and encryption in CS territory.GMSC (gateway mobile switching center) 143 is webmasters of mobile switching centre (Mobile Switching Center, be called for short " MSC "), is responsible for fixing with other or being connected of mobile network.

GPRS serving GPRS support node 141 is the equipment that connects UMTS Terrestrial radio access network 12 and gateway GPRS supporting node (GGSN) 144, finish functions such as routing forwarding, mobile management, it generally be with UMTS Terrestrial radio access network 12 at same Routing Area (Route Area, be called for short " RA "); Gateway GPRS supporting node (GGSN) 144 is that promptly core net 14 links to each other with external data network 151 in the external network 15 by it with the interface of interconnection protocol between extranets (Internet Protocol is called for short " IP ") packet network.Simultaneously, core net 14 is by PLMN (the Public Lands Mobile Network in GMSC (gateway mobile switching center) 143 and the external network 15, be called for short " PLMN ")/public switched telephone network (Public Switched Telephone Network, be called for short " PSTN ")/integrated services digital network (Integrated Services Digital Network is called for short " ISDN ") waits other network 150 to connect.

In the external network 15, other network 150 such as PLMN/PSTN/ISDN is some Circuit Switching Networks, and external data network 151 comprises that Internet/Intranet is the packet switching network.

GGSN is WCDMA core net PS domain-functionalities nodes, links to each other with SGSN by the Gn/Gp interface, and promptly the Gn/Gp interface 145 among Fig. 1 links to each other with external data network 151 by the Gi interface, i.e. Gi interface 16 among Fig. 1.GGSN provides route and the encapsulation of packet between WCDMA mobile network and external data network.

SGSN is WCDMA core net PS domain-functionalities nodes, and it links to each other with UTRAN by the Iu_PS interface, need to prove that the Iu_PS interface is a type of lu interface 13.It also links to each other with GGSN by the Gn/Gp interface, i.e. Gn/Gp interface 145 among Fig. 1; Link to each other with HLR/AUC by Gr interface, i.e. Gr interface among Fig. 1 146; By Gs interface and MSC/VLR, i.e. Gs interface among Fig. 1 147.It is by CAP interface and service control point (Service Control Point in addition, be called for short " SCP ") link to each other, by Gd interface and (the Short Message Center of short message service center, be called for short " SMC ") link to each other, link to each other by Ga interface and charging gateway (Charging Gateway is called for short " CG ").The major function of SGSN provides the functions such as routing forwarding, mobile management, session management, authentication and encryption in PS territory.

Interface between SGSN and the GGSN is based on wireless universal packet service tunnel protocol (GPRSTunneling Protocol is called for short " GTP ") agreement and realizes the tunnel transmission function, comprises signaling plane GTP-C and user's face GTP-U.GTP-C finishes the management in tunnel and the transfer function of other signaling message, the packet of GTP-U transmission user face.3GPP29060 protocol specification definition GTP, as (the General Packet Radio Service of GPRS in the UMTS/GPRS backbone network, abbreviation " GPRS ") agreement between support node comprises GTP chain of command agreement (GTP-C) and transfer of data (GTP-U) process.This standard has also been listed based on the message (Message) of the charging protocol GTP of GTP agreement and information element (IE), and details is seen GSM 12.15 standards.

If ME needs and external data network 151 is carried out exchanges data, it must at first connect, after the successful connection, it also need to obtain an IP address and and external data network 151 connect, just carry out packet data protocol (Packet Data Protocol is called for short " PDP ") context activation process.This process situation in different networks is different, is described in activation in GPRS and the UTMS network respectively below in conjunction with Fig. 2 Fig. 3.

Fig. 2 is the signaling flow graph of the pdp context activation in the prior art GPRS network.

As shown in Figure 2, this process relates to 4 parts and the two kinds of algorithm process processes in the gprs system, be respectively travelling carriage (Mobile Station, be called for short " MS ") 20, base station system (Base StationSystem, be called for short " BSS ") 21, second generation GPRS serving GPRS support node (2G-ServingGPRS Support Node, be called for short " 2G-SGSN ") 22, second generation gateway GPRS supporting node (GGSN) (2G-GPRS Gateway Support Node, be called for short " 2G-GGSN ") 23, and cell selecting algorithm C1 algorithm 24 and sub-district reselection algorithm C2 algorithm 25.Wherein step 201 and step 202 quilt of C1 algorithm in Fig. 2 uses, and the C2 algorithm uses in a step 206 and step 207 quilt.

In step 201, travelling carriage 20 sends the packet data protocol context activation request to second generation GPRS serving GPRS support node 22, that is to say that MS sends Activate PDP ContextRequest message to SGSN.MS will use pdp address to indicate it whether to ask to use static PDP address or dynamic PDP addresses.When dynamic address was used in request, MS was changed to sky with pdp address.MS can use access point name (Access Point Name is called for short " APN ") to select the reference point to certain external network, or selects service by it.Need to prove that this activates request message is to transmit through the tunnel that the GTP agreement of base station system 21 is set up, and is equivalent to through base station system 21 transparent transmissions.

Next, in step 202, because be in GPRS network, promptly the interface A/Gb between base station system 21 and the second generation GPRS serving GPRS support node 22 is a pattern, and safety function may be performed so.Be may carry out security inspection between the two, promptly 2G-SGSN carries out discriminating of MS identity and equipment inspection.

Subsequently, same because be in GPRS network in step 203, interface if base station system 21 is followed the tracks of activates under the A/Gb pattern, second generation GPRS serving GPRS support node 22 should send and call the path signaling to base station system 21, and promptly 2G-SGSN sends Invoke Trace to BSS.The specifying information that comprises in the Invoke Trace message, i.e. reference path (Trace Reference) and path type (Trace Type) they are from HLR or OMC operation and maintenance centre (Operations﹠amp; MaintenanceCenter is called for short " OMC ") in the trace information that receives directly take.

After this, in step 204, if identity is differentiated and equipment inspection has all been passed through, the PDP message information that second generation GPRS serving GPRS support node 22 provides by travelling carriage 20 is set up and the packet data protocol context request of 23 of second generation gateway GPRS supporting node (GGSN)s, be the optional PDP Type of SGSN by providing by MS, optional PDP Address, with optional APN, and Activate PDP Context Request verified in the signatory record of PDP context.

Step 205 is exactly the sound that 23 pairs of second generation GPRSs of second generation gateway GPRS supporting node (GGSN) serving GPRS support node 2 is set up packet data protocol context request, and promptly 2G-GGS returns and sets up the PDP Context response.

Then, also because be in GPRS network, interface is in the A/Gb pattern in step 206, and BSS packet flow context process may be performed, and promptly base station 21 and second generation GPRS serving GPRS support node 22 may be carried out the packet flow context of base station process.

At last, to step 207, insert Network Service Access Point Identifier (Network ServiceAccess Point Identifier is called for short " NSAPI ") behind the GGSN address of second generation GPRS serving GPRS support node 22 in its PDP context.If MS asks a dynamic address, the pdp address of receiving from second generation gateway GPRS supporting node (GGSN) 23 is inserted into the PDPcontext.SGSN is based on service quality (the Quality of Service that consults, be called for short " QoS ") selection Radio priority level and stream of packets sign (Packet Flow Id), and return packet data protocol context activation and finish message, promptly Activate PDP Context Accept has wherein comprised PDP Type, PDPAddress, TI, QoS Negotiated, Radio Priority, Packet Flow Id, PDP ConfigurationOptions message is given MS.SGSN can send PDP PDUs now between GGSN and MS, and starts charging.In this step, if SGSN successfully upgrades GGSN, then the PDPcontext that MS is relevant will be kept in the related entities.If PDP Context Activation procedure failure, if or SGSN returns the packet data protocol context activation refuse information, be that Activate PDP Context Reiect has wherein comprised Cause, PDP Configuration Options message, MS can attempt the activation of another identical APN so, up to the maximum times that allows.If MS has GPRS-CSI, it is mutual then to need to carry out CAMEL, and related procedure is defined in 23.078.

Fig. 3 is the signaling flow graph of the pdp context activation in the prior art UTMS network.

As shown in Figure 3, this process relates to 4 parts and the two kinds of algorithm process processes in the UTMS system, be respectively travelling carriage 30, UMTS Terrestrial radio access network 31, third generation GPRS serving GPRS support node (3G-Serving GPRS Support Node, be called for short " 2G-SGSN ") 32, third generation gateway GPRS supporting node (GGSN) (3G-GPRS Gateway Support Node, be called for short " 2G-GGSN ") 33, and cell selecting algorithm C1 algorithm 34 and sub-district reselection algorithm C2 algorithm 35.Wherein step 301 and step 302 quilt of C1 algorithm in Fig. 3 uses, and the C2 algorithm uses in a step 308 and step 309 quilt.

Equally, in the UMTS network, step 301, travelling carriage 30 sends the packet data protocol context activation request to third generation GPRS serving GPRS support node 32, that is to say that MS sends ActivatePDP Context Request message to SGSN.MS will use pdp address to indicate it whether to ask to use static PDP address or dynamic PDP addresses.When dynamic address was used in request, MS was changed to sky with pdp address.MS can select a reference point to certain external network with APN, or selects service by it.Need to prove that this activates request message is to transmit through the tunnel that the GTP agreement of UMTS Terrestrial radio access network 31 is set up at this moment, is equivalent to through UMTS Terrestrial radio access network 31 transparent transmissions.

After this, in step 302, the PDP message information that third generation GPRS serving GPRS support node 32 provides by travelling carriage 30 is set up and the packet data protocol context request of 33 of third generation gateway GPRS supporting node (GGSN)s, be the optional PDPType of SGSN by providing by MS, optional PDP Address, with optional APN, and Activate PDP Context Request verified in the signatory record of PDP context.

Step 303 is exactly the sound that 33 pairs of second generation GPRSs of third generation gateway GPRS supporting node (GGSN) serving GPRS support node 32 is set up packet data protocol context request, and promptly 3G-GGS returns and sets up the PDP Context response.

Next, in step 304, because be in the UMTS network, so the interface Iu between UMTS Terrestrial radio access network 31 and the second generation GPRS serving GPRS support node 32 is a pattern, in this step, RAB (Radio Access Bearer is called for short " RAB ") is set up by RABAssignment procedure.

In the Iu pattern, if the BSS among the UTRAN follow the tracks of to activate, then in the step 305,3G-SGSN should send Invoke Trace message to UTRAN, and Trace Reference and Trace Type come from the trace information copy that HLR or OMC receive.

After this, if the QoS attribute is lowered in the context of step 302 and step 303 is connected, step 306,3G-SGSN should pass through the request of update packet data protocol contexts, i.e. the relevant 3G-GGSN of Update PDPContext Request message informing.

Later step 307,3G-GGSN is by returning the response of update packet data protocol contexts, the i.e. new QoS attribute of Update PDP Context Response message confirmation.

At last, to step 308, insert Network Service Access Point Identifier NSAPI behind the GGSN address of third generation GPRS serving GPRS support node 32 in its PDP context.If MS asks a dynamic address, the pdp address of receiving from second generation gateway GPRS supporting node (GGSN) 33 is inserted into the PDP context.SGSN selects Radio priority level and stream of packets sign (Packet Flow Id) based on the QoS that consults, and return packet data protocol context activation and finish message, be Activate PDP Context Accept, wherein comprised PDP Type, PDP Address, TI, QoSNegotiated, Radio Priority, Packet Flow Id, PDP Configuration Options message is given MS.SGSN can send PDP PDUs now between GGSN and MS, and starts charging.In this step, if SGSN successfully upgrades GGSN, then the PDP context that MS is relevant will be kept in the related entities.If PDP Context Activation procedure failure, if or SGSN returns the packet data protocol context activation refuse information, be that Activate PDP Context Reject has wherein comprised Cause, PDP Configuration Options message, MS can attempt the activation of another identical APN so, up to the maximum times that allows.

In the prior art, the activation PDP Context request that defines in the GTP tunnel administrative messag is handled as follows:

At first, the SGSN node will send to the GGSN node " creates the PDP Context request information; the purpose IP address of this message is first IP address of the GGSN IP address list that provides of DNS (Domain Name System is called for short " DNS ") server.

After this, SGSN mark PDP Context is " wait-for-response ".In this state, SGSN should receive the G-PDU from GGSN, but does not send to MS.

Then, effective request is initiated PDP Context among the SGSN and the tunnel creation between the PDP Context among the GGSN.If this process does not have finishing of success, SGSN repeats the PDP Context constructive process with the next GGSN address of IP address list, until using up all GGSN addresses.If not success has been used up still in the GGSN address in the tabulation, activation is failure just.

In actual applications, there is following problem in such scheme: do not consider the situation of actual on-line apparatus operation and the demand of mobile operator comprehensively.Specifically, can't specifically solve mobile operator the demand that need forbid that new user connects is arranged.

In actual use, mobile operator often need forbid that new user connects.For example, need online some configuration modification that carries out the attendant, but the newly-increased instability that may bring debugging that is connected with; It is too much that perhaps the attendant inquires active user's number, might cause system's overload operation, need forbid temporarily that the user who increases newly reaches the standard grade; Perhaps the Operation and Maintenance personnel are because some reason, the process that need temporarily forbid certain APN of user capture, or the like.These situations all need a kind of method of GGSN business that can lock as temporarily forbidding the means that the user reaches the standard grade.But as mentioned above, prior art can't realize this business.

Summary of the invention

In view of this, main purpose of the present invention is to provide a kind of locking means of gateway GPRS supporting node (GGSN) service, can satisfy the demand that mobile operator forbids Adding User and reaches the standard grade, not only can lock the business of whole GGSN veneer, and can lock the business of certain APN of visit that Adds User.Satisfy the situation of actual on-line apparatus operation and the demand of mobile operator thus more all sidedly.

For achieving the above object, the invention provides a kind of locking means of gateway GPRS supporting node (GGSN) service, when A receives activation request message from the GPRS serving GPRS support node when gateway GPRS supporting node (GGSN), according to lock token, whether the veneer of judging this activation solicited message correspondence is locked, if, execution in step C then, otherwise execution in step B;

The described gateway GPRS supporting node (GGSN) of B is according to the APN of described activation request message correspondence, and queries configuration database judges whether this APN is locked, if, execution in step C then, otherwise execution in step D;

The described gateway GPRS supporting node (GGSN) of C sends to described GPRS serving GPRS support node and activates failure response message, finishes then;

The described activation request message of D normal process.

Wherein, described step B also comprises following substep:

The described gateway GPRS supporting node (GGSN) of B1 is judged described activation request message whether for once activating, if, then from this message, take out APN, and execution in step B3, otherwise execution in step B2;

The described gateway GPRS supporting node (GGSN) of B2 takes out APN from relevant once the activation the message, and execution in step B3;

B3 inquires about described configuration database according to described APN, judges whether this APN is locked, if, execution in step C then, otherwise execution in step D.

In described step C, the cause value in the described activation failure response message is " service is not supported ".

Described gateway GPRS supporting node (GGSN) comprises at least one service board, and in described steps A, when described gateway GPRS supporting node (GGSN) is received activation request message from described GPRS serving GPRS support node, activate the lock token of the pairing service board of request message according to this, judge whether this service board is locked, if, execution in step C then, otherwise execution in step B.

Described gateway GPRS supporting node (GGSN) is according to the lock arrangement order from the Operation and Maintenance personnel, and self lock token is provided with.

Described gateway GPRS supporting node (GGSN) is provided with lock token according to the lock arrangement order from the Operation and Maintenance personnel in the configuration database of APN.

By relatively finding that technical scheme difference with the prior art of the present invention is that on the one hand, for the activation request message from SGSN, GGSN will judge whether self is locked according to lock token; Perhaps according to the APN of described activation request message correspondence, queries configuration database judges whether this APN is locked, if locked, then send and activates failure response, thereby reach the purpose of forbidding Adding User and reaching the standard grade.

On the other hand, when GGSN handles request message from SGSN, at first the type of this request message is distinguished,, the activation request message is carried out preliminary treatment upgrading and the deexcitation request message carries out normal process.Thus, satisfying the demand while that mobile operator forbids Adding User and reaches the standard grade, guarantee to lock later GGSN again and still can successfully handle updating message and deactivation message.

Difference on this technical scheme, brought comparatively significantly beneficial effect, make the Operation and Maintenance personnel can lock the business of whole GGSN veneer as required, or the locking Add User the visit certain APN business, thereby satisfy the demand that mobile operator forbids Adding User and reaches the standard grade, also consider the situation of actual on-line apparatus operation and the demand of mobile operator more all sidedly.

Embodiment

For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.

Generally speaking, principle of the present invention is, by the configuration order of locking GGSN business, make the Operation and Maintenance personnel can lock the some single board services of GGSN as required, or all veneers is at the business of some APN; Simultaneously, when GGSN receives activation request message from SGSN,, judge whether self is locked according to lock token; Perhaps according to the APN of described activation request message correspondence, queries configuration database judges whether this APN is locked, if locked, then send and activates failure response.It is pointed out that to lock later GGSN, still can handle updating message and deactivation message, but can not handle activation message, reached the purpose of forbidding Adding User and reaching the standard grade like this according to above-mentioned principle of the present invention.

In the present invention, when the Operation and Maintenance personnel need forbid that the user reaches the standard grade by locking GGSN business, the configuration order of locking GGSN piece single board service can be set.Configuration order sends to corresponding veneer with lockout message by the message transmit mechanism, and corresponding veneer is received after the message lock flag set.

In other words, the configuration order interface that the Operation and Maintenance personnel can provide by equipment locks the business of different veneers.Certainly, the business of blocked veneer also can be removed by corresponding configuration order.In the present invention, the configuration order of locking can be carried out when veneer has the user and do not have the user.

In the present invention, the configuration order of locking can be carried out when veneer has the user and do not have the user.

Need to prove, GGSN is made of the polylith veneer, each piece veneer all has a Gn mouth IP address, be equivalent to a GGSN address in logic, the concrete business that each veneer may carry according to actual needs is different, promptly concerning SGSN, in the face of the GGSN of the concrete Service Gateway conversion of a plurality of execution, these GGSN in logic just are presented as a service node physically of carrying out the conversion of miscellaneous service gateway with the overall system viewpoint in logic.

Except locking the business of different veneers, can also lock certain APN business according to Operation and Maintenance personnel's needs in the present invention.Specifically, the Operation and Maintenance personnel can lock the business of all veneers at certain APN by the configuration order interface that equipment provides, simultaneously by configuration order also can all veneers of release at the business of certain APN.This configuration order can be carried out when APN has the user and do not have the user.Configuration order will be added relative recording in the configuration database for APN, keep the lock token of this APN.

Need to prove the shared APN database of all veneers, the server difference of the APN that each is different.And upward each veneer disposal ability is limited owing to GGSN, for the bigger business at certain APN of data flow, may need common processing of a plurality of veneers to finish.

In order to inquire about certain veneer lock-out state, the Operation and Maintenance personnel can inquire about the lock-out state of certain piece veneer by the configuration order interface that equipment provides, and this sends to corresponding veneer by the message transmit mechanism with query messages and realizes; On the other hand, if inquire about the lock-out state of certain APN, then be to realize by the configuration database that reads APN.

Below in conjunction with Fig. 4, describe in detail among the present invention, GGSN is to the implementation procedure from the SGSN Message Processing.

At first, in step 4000, GGSN receives the solicited message from SGSN, and will take different counter-measures according to concrete request message.Specifically, if GGSN receives is to upgrade and the deexcitation request message, then will enter step 4120; If GGSN receives is to activate request message then enter step 4200.

In step 4120, renewal and the deexcitation request message of GGSN to receiving do not judged lock token, the message that normal process SGSN transmits.That is to say and be specifically responsible for certain veneer of handling this renewal and deexcitation request message that for renewal of receiving and deexcitation request, do not inquire about its lock token, lock token will not influence the former user's who pre-exists of GGSN Business Processing process like this.

If what GGSN received is to activate request message, then enter step 4200, in this step, judge the lock flag position of this piece veneer, this is to receive that the code of request message is located in above the veneer because judge, just known veneer number according to code message with regard to the finger daemon among the GGSN, so can judge directly whether this veneer has locked.The request message that sends is actually according to the IP address of the GGSN of request message and selects veneer, every veneer all has an IP address, that is to say all suitable GGSN in logic of every veneer, so can correspond to every veneer according to request message, request message sends to above the corresponding veneer according to the IP address earlier, is judging what whether this veneer locked then.If finding this veneer is lock-out state, then enter step 4410.Otherwise enter step 4300.

In step 4410, GGSN does not allow the user activate, and directly returns the activation failure response to SGSN, and wherein, cause value is " service is not supported ".

If it is locked to judge that in step 4200 this veneer does not have, then in step 4300, carry out message inspection, judge whether it is once to activate.If once activate, then enter step 4310, otherwise enter step 4400.

In step 4310, from above-mentioned activation request message, take out APN, according to this APN queries configuration database, judge whether this APN is locked,, then enter step 4410 if locked, as mentioned above, GGSN returns the activation failure response in this step, and its cause value is " service is not supported ".If APN is not locked, then enter step 4320.

In step 4320, because judge that the APN in the above-mentioned activation request message is not locked, therefore, normal process once activates message in this step.

In step 4400, owing to judge that in step 4300 activating request message is not once to activate, because of because secondary activating and once the activation all above same mobile phone, send, so for simply, 3GPP.29060 agreement regulation secondary activating has obtained a lot of shared information from the context that once activates, APN is exactly a shared information.If it is locked that judgement once activates the APN that takes out the message from being correlated with, then enter step 4410, promptly send and activate failure response, its cause value is " serve and do not support ".If this APN is not locked, then enter step 4500.

In step 4500, normal process secondary activating message.

Once activation and secondary activating all are the block domain data activation that mobile phone is initiated, mobile phone by once or secondary activating set up GPRS tunnel and context, for mobile phone data service such as surf the Net establishes the tunnel that closes contextual information and transfer of data, mobile phone can utilize this tunnel and context to carry out data communication subsequently.

Once activate and the secondary activating main distinction is that the trafficwise that carries out of mobile phone is different, for instance, mobile phone needs to carry out an once activation in order to carry out the business of file in download before; Appreciate real-time film if need to carry out again streaming media service this time again, so just may need to carry out a secondary activating; These two kinds of business all have very big difference to requirements such as service quality, so need different contexts to distinguish.

Though by reference some preferred embodiment of the present invention, the present invention is illustrated and describes, but those of ordinary skill in the art should be understood that, can do various changes to it in the form and details, and the spirit and scope of the present invention that do not depart from appended claims and limited.
