Description

The processing method of conflict talk and device

Technical field

The present invention relates to the communications field, in particular to a kind of processing method and device of conflict talk.

Background technology

Fig. 1 is existing third generation partner program (3rd Generation Partnership Project; Abbreviate 3GPP as) grouping system (the Evolved Packet System of evolution; Abbreviate EPS as) the composition configuration diagram; Shown in Figure 1 is the EPS network architecture of non-roaming scene, comprises UMTS land radio access web (Evolved UniversalTerrestrial Radio Access Network abbreviates E-UTRAN as), mobile management unit (the Mobility ManagementEntity of evolution; Abbreviate MME as), gateway (Serving Gateway; Abbreviate S-GW as), grouped data network gateway (PacketDataNetwork Gateway abbreviates P-GW as, is also referred to as PDN GW), home subscriber server (Home SubscriberServer; Abbreviate HSS as), "Policy and Charging Rules Function (Policy and Charging Rules Function abbreviates PCRF as) entity and other support nodes form.

Wherein, PCRF is the core of the strategy and the control (Policy and Charging Control abbreviates PCC as) of chargeing, and is responsible for the formulation of strategic decision-making and charging regulation.PCRF provides the network control rule based on business data flow; These network controls comprise detection, gate (Gating Control), service quality (Quality of Service the abbreviates QoS as) control of business data flow and based on the charging regulation of data flow etc.PCRF sends to strategy and charge execution function (Policy and Control Enforcement Function abbreviates PCEF as) execution with the strategy and the charging regulation of its formulation, and simultaneously, PCRF need guarantee that also these rules are consistent with user's CAMEL-Subscription-Information.PCRF generates strategy and the foundation of charging regulation comprises: obtain and professional relevant information from application function (Application Function abbreviates AF as); Obtain user policy, billing control and subscription information from user-subscribed database (SubscriptionProfile Repository abbreviates SPR as); Obtain and carry the information of network of relation from PCEF.

EPS supports the intercommunication with non-3 GPP system, and the intercommunication of EPS and non-3 GPP system realizes that through the S2a/b/c interface P-GW is as the anchor point between 3GPP and non-3 GPP system.As shown in Figure 1, wherein non-3 GPP system is divided into the non-3GPP IP access of trusted and trustless non-3GPP IP access.The non-3GPP IP of trusted inserts and can directly be connected with P-GW through the S2a interface; Trustless non-3GPP IP inserts packet data gateway (the Evolved Packet Data Gateway that needs through evolution; Abbreviate ePDG as) link to each other with P-GW; Interface between ePDG and P-GW is the S2b interface; And adopt Internet protocol safety (IPSec) that signaling and data are carried out encipherment protection between subscriber equipment (UserEquipment abbreviates UE as) and the ePDG.The S2c interface provides subscriber equipment and user plane relevant control and mobility support between the P-GW, and the mobility management protocol of its support is for supporting the mobile IP v 6 (being DSMIPv6, two stack mobile IP v 6s) of two stacks.

At present, a lot of operators pay close attention to fixed network and move fusion (Fixed Mobile Convergence abbreviates FMC as), and study to 3GPP and broadband forum (Broadband Forum abbreviates BBF as) interconnection and interflow.For the scene of user, need the QoS on the whole transmission path (data can be passed through fixed network and mobile network transmission) of data be guaranteed through fixed broadband Access Network (Fixed Broadband Access Network abbreviates FBAN as) access mobile core net.In the current techniques, carry out mutual (being called the S9* session among the present invention), realize that QoS ensures through the broadband policy control architecture in PCRF and the fixed broadband Access Network (Broadband Policy Control Framework abbreviates BPCF as).BPCF is the policy control architecture in the fixed broadband Access Network; Resource request message to PCRF; The network strategy that BPCF inserts according to fixed broadband, CAMEL-Subscription-Information etc. carry out resource and admission control or resource request message are transmitted to the network element that other fixed broadbands insert; Like the broadband is network gateway (Broadband Network Gateway abbreviates BNG as), carries out resource and admission control (promptly entrusting other network elements to carry out resource and admission control) by other network elements again.Such as: when UE passes through WLAN (Wireless Local; Abbreviate WLAN as) when inserting the 3GPP core net; Be no more than the bandwidth (maximum bandwidth of supporting like signatory bandwidth or this circuit) of this circuit for the total bandwidth need of all UE access service of guaranteeing to insert through WLAN line attachment; PCRF need be mutual with BPCF when carrying out the QoS mandate, so that the fixed broadband Access Network is carried out the admittance control of resource.

Fig. 2 and Fig. 3 are respectively in the prior art, and UE inserts the non-roaming of 3GPP core net and roaming configuration diagram through the fixed broadband Access Network, and wherein the fixed broadband Access Network inserts as fly-by-night non-3GPP.

Fig. 4 is in the prior art, and UE wherein adopts PMIPv6 (being proxy mobile IPv 6) agreement through the flow process of fixed broadband Access Network access 3GPP core net between ePDG and the P-GW, and concrete steps are following:

After step S401:UE inserts the fixed broadband connecting system, carry out access authentication.

Step S402: the fixed broadband connecting system is that UE distributes local ip address.

Step S403: receive the triggering of step S401 and step S402, BPCF is notified UE just to insert through the fixed broadband Access Network.

Step S404:BPCF sends gateway control session to PCRF and sets up message, carries ID, UE local ip address in the message.

Step S405:PCRF returns acknowledge message to BPCF.

After step S406:UE obtains local ip address; UE initiates IKEv2 (Internet Key Exchange protocol version2; The internet key exchange version 2) tunnel establishment procedure; And adopt EAP (Extensible Authentication Protocol, Extensible Authentication Protocol) to carry out authentication.EPDG and authentication and authorization charging server (Authentication, Authorization andAccounting Server; Abbreviate AAA Server as) mutual; AAA Server further with home subscriber server (HomeSubscriber Server; Abbreviate HSS as) mutual, to accomplish the EAP authentication.

Step S407:ePDG sends gateway control session to PCRF and sets up message, sets up in gateway control session and carries ID, Packet Data Network's (Packet DataNetwork abbreviates PDN as) sign and UE local ip address in the message.Alternatively, if when detecting NAT (Network Address Translation, network address translation), also possibly carry User Data Protocol (User Date Protocol abbreviates UDP as) source port number.This moment, the UE local ip address was the IP address (having NAT between UE and the ePDG) behind IP address allocated in the step 402 (not having NAT between UE and the ePDG) or the process NAT.

In this step, ePDG also can send DHCP (Dynamic Host ConfigureProtocol abbreviates DHCP as) request message to PCRF, carries ID, PDN sign and UE local ip address in the message.Alternatively, if when detecting NAT, also possibly carry the UDP source port number.

Step S408:PCRF returns acknowledge message to ePDG.

Step S409: receive the triggering of step S407, PCRF confirms BPCF according to the UE local ip address, and PCRF sends PCRF initiation gateway control session to BPCF and sets up message, carries ID, UE local ip address, UDP source port number in the message.

Step S410:BPCF returns acknowledge message to PCRF.

After step S411:ePDG selects P-GW, send agent binding update messages, in agent binding update messages, carry ID and PDN sign to P-GW.

Step 412:P-GW is UE distributing IP address; Send IP-CAN (IP-ConnectivityAccessNetwork to PCRF; IP connected reference network) Indication message is set up in session, sets up in the IP-CAN session to carry ID, PDN sign in the Indication message and be the UE IP address allocated.

Step S413:PCRF formulates PCC rule and QoS rule.PCRF returns acknowledge message to PCEF, carries the PCC rule.

Step S414:P-GW is saved in HSS with its own IP address.

Step S415:P-GW returns proxy binding acknowledgment messages to ePDG, in proxy binding acknowledgment messages, carries promising UE IP address allocated.

Step S416: the agent binding update success, set up ipsec tunnel between UE and the ePDG.

Step S417:ePDG sends the last item IKEv2 signaling to UE, wherein carries the IP address of UE.

In above-mentioned flow process, the prerequisite of the execution of step 401-step 405 is that UE and fixed broadband Access Network must be supported 3GPP-based (promptly based on 3GPP) access authentication.Because ePDG can't know UE and when inserting the fixed broadband Access Network, whether carry out the 3GPP-based access authentication; Just do not know also whether BPCF has initiated to have set up the S9* session, so ePDG always provides the local ip address of UE to be used to trigger PCRF to PCRF to initiate to set up the S9* session.When if PCRF initiates to set up the S9* session in decision, PCRF does not receive that also BPCF initiates the S9* session of setting up.At this moment, with existing BPCF and PCRF all to initiate to set up the flow process of S9* session, cause session to be set up and conflict occurs.To this problem, effective solution is not proposed as yet at present.

Below in conjunction with instance above-mentioned preferred embodiment is elaborated.

Instance one:

The UE of being shown in Figure 6 inserts the attachment flow of 3GPP core net through trustless fixed broadband Access Network; This flow process can solve BPCF and PCRF initiates the problem that conflict is set up in the S9* session simultaneously; Wherein adopt the PMIPv6 agreement between ePDG and the P-GW, specifically may further comprise the steps:

After step S602:UE inserts the fixed broadband connecting system, carry out access authentication.

Step S604: the fixed broadband connecting system is that UE distributes local ip address.

Step S606: receive the triggering of step S602 and step S604, BPCF is notified UE just to insert through the fixed broadband Access Network.

Step S608:BPCF sends gateway control session to PCRF and sets up message, carries ID, UE local ip address in the message.

Step S610:PCRF returns acknowledge message to BPCF.

After step S612:UE obtained local ip address, UE initiated the IKEv2 tunnel establishment procedure, and adopted EAP to carry out authentication, and ePDG and AAA Server are mutual, and AAA Server is further mutual with HSS, to accomplish the EAP authentication.

Step S614:ePDG sends gateway control session to PCRF and sets up message, sets up in gateway control session and carries ID, PDN sign and UE local ip address in the message.When detecting NAT, also need carry the UDP source port number.This moment, the UE local ip address was the IP address (having NAT between UE and the ePDG) behind IP address allocated among the step S604 (not having NAT between UE and the ePDG) or the process NAT.

In this step, ePDG also can send the DHCP request message to PCRF, carries ID, PDN sign and UE local ip address in the message.When detecting NAT, also need carry the UDP source port number.

Step S616:PCRF returns acknowledge message to ePDG.

Step S618: receive the triggering of step S614, PCRF confirms BPCF according to the UE local ip address, and PCRF sends PCRF initiation gateway control session to BPCF and sets up message, carries ID, UE local ip address, UDP source port number in the message.

Step S620: if this moment, BPCF initiated to set up the S9* session to PCRF, BPCF returns acknowledge message to PCRF, in message, carries BPCF and has initiated to set up S9* session indication.

This indication can adopt one of following dual mode to realize:

(1) a newly-increased Result-Code AVP (result code value attribute value to) value promptly defines a kind of new error code.BPCF returns this error code to PCRF, directly refuses the S9* session foundation that PCRF initiates.

(2) the new AVP of definition, notice PCRF has two S9* sessions to set up at this moment.When PCRF receives this indication, initiate the flow process of one of them S9* session of termination by the PCRF decision.

After step S622:ePDG selects P-GW, send agent binding update messages, in agent binding update messages, carry ID and PDN sign to P-GW.

Step S624:P-GW is UE distributing IP address, sends the IP-CAN session to H-PCRF and sets up Indication message, sets up in the IP-CAN session to carry ID, PDN sign in the Indication message and be the UE IP address allocated.

Step S626:PCRF formulates PCC rule and QoS rule.PCRF returns acknowledge message to PCEF, carries the PCC rule.

Step S628:P-GW is saved in HSS with its own IP address.

Step S630:P-GW returns proxy binding acknowledgment messages to ePDG, in proxy binding acknowledgment messages, carries promising UE IP address allocated.

Step S632: the agent binding update success, set up ipsec tunnel between UE and the ePDG.

Step S634:ePDG sends the last item IKEv2 signaling to UE, wherein carries the IP address of UE.

Step S636:PCRF sends the message of request termination gateway control session according to the indication of step 510 to ePDG;

Step S638:ePDG returns acknowledge message to PCRF.

In above-mentioned instance, be to judge that by BPCF conflict has taken place in S9* session foundation, and in the affirmation message that PCRF returns, carry the indication that BPCF has initiated to set up the S9* session, thereby the S9* session that makes PCRF initiate to set up is not set up at BPCF.Similarly, can judge that conflict has taken place in S9* session foundation yet, and in the affirmation message that BPCF returns, carry the indication that PCRF has initiated to set up the S9* session, thereby the S9* session that makes BPCF initiate to set up is not set up at PCRF by PCRF.
