Description

The processing method of many bearing bindings and event reporting function and system
Technical field
The present invention relates to IP and connect Access Network session (IP-CAN, IP Connectivity Access Network) technology, relate in particular to the processing method and the system of a kind of many bearing bindings and event reporting function.
Background technology
Fig. 1 is the grouping system (EPS of existing evolution, the composition schematic diagram of system architecture Evolved Packet System), as shown in Figure 1, third generation partner program (3GPP, 3rd Generation PartnershipProject) EPS comprises: the Universal Terrestrial Radio Access Network (E-UTRAN of evolution, Evolved UniversalTerrestrial Radio Access Network), mobile management unit (MME, Mobility ManagementEntity), gateway (S-GW, Serving Gateway), grouped data network gateway (P-GW, PacketData Network Gateway), home subscriber server (HSS, Home Subscriber Server), 3GPP authentication and authorization charging (AAA) server, strategy and charging rule functions (PCRF, Policy and ChargingRules Function) and other support node are formed.
Wherein, MME is used for the related work of chains of command such as the processing of mobile management, Non-Access Stratum signaling and the contextual management of user's mobile management; S-GW is the accessing gateway equipment that links to each other with E-UTRAN, is used for transmitting data between E-UTRAN and P-GW, and is responsible for pending datas such as paging are carried out buffer memory; P-GW is the borde gateway of EPS and packet data network (PDN, Packet Data Network), and the access that is used for responsible PDN reaches functions such as transmitting data between EPS and PDN.
EPS supports the intercommunication with non-3GPP network, and by the intercommunication of S2a/b/c interface realization with non-3GPP network.Non-3GPP network comprises the non-3GPP network of trusted and trustless non-3GPP network.Wherein, the IP of the non-3GPP network of trusted inserts and can directly link to each other with P-GW by S2a; The IP of trustless non-3GPP network inserts the data gateway (ePDG, Evolved Packet Data Gateway) that needs through evolution and links to each other with P-GW, and the interface between ePDG and P-GW is S2b.Subscriber equipment (UE, User Equipment) also can adopt the DSMIPv6 agreement to link to each other with P-GW by the S2c interface.
Control (the PCC if EPS system support policy charges, Policy and Charging Control) PCRF carries out the formulation of strategy and charging regulation, so, the EPS system is by receiving interface Rx and the Internet protocol (IP of operator, Internet Protocol) business network links to each other, and obtains business information; In addition, the EPS system links to each other with gateway device in the network by the Gx/Gxa/Gxc interface, is responsible for initiating the foundation of IP carrying, the service quality (QoS, Quality of Service) of assurance business datum, and the control of chargeing.
Wherein, strategy and charge execution function (PCEF, Policy and Charging EnforcementFunction) are arranged in P-GW, pass through Gx interface exchange message between PCRF and P-GW.Interface when between P-GW and S-GW is based on proxy-mobile IP (PMIP, Proxy Mobile IP) time, there are bearing binding and event reporting function (BBERF among the S-GW, Bearer Binding and Event ReportFunction), and between S-GW and the PCRF by Gxc interface exchange message.When the non-3GPP network insertion of trusted, the trusted non-3 GPP access network Central Shanxi Plain is also resident BBERF, between non-3GPP network access gateway of trusted and the PCRF by Gxa interface exchange message.During the UE roaming, the interface of ownership place PCRF (hPCRF) and visit ground PCRF (vPCRF) is the S9 interface, simultaneously, and for UE provides professional application function (AF, Application Function) is arranged in business network, sends the business information that is used to generate the PCC strategy to PCRF by Rx interface.
In present technology, the agreement that adopts in the PCC framework is the Diameter application protocol of development on Diameter basic agreement (DiameterBase Protocol) basis.For example, be applied to the application protocol of Gx interface, the application protocol and being applied to that is applied to application protocol, the Gxx interface (comprising Gxa and Gxc interface) of Rx interface is roamed the application protocol of interface S9 etc.In these application protocols, defined be used for PCC message, order and property value to (AVP, Attribute Value Pairs) etc.The Diameter session of setting up with these agreements can become Gx session, Gxx session, Rx session and S9 session respectively.Each functional entity of PCC carries out policy and charging control by the PDN connection that these sessions are set up the UE access network.The PCC framework has defined the Diameter application protocol that uses under non-roaming scene at present, for example, is applied to the application protocol of Gx interface, is applied to the application protocol of Rx interface and the application protocol of Gxx interface (comprising Gxa and Gxc interface) etc.Message, order and the AVP etc. that are used for PCC in these application protocols, have been defined.
In the prior art, an IP-CAN session relates to a plurality of network elements.In order to obtain the policy control rule that this IP-CAN session is controlled or the information of the control law that is provided for generating strategy, each network element will be set up the Diameter session respectively with PCRF.Like this, IP-CAN session will with a plurality of Diameter session associations, these Diameter sessions all adopt Diameter to set up, keep and delete.
Gravity treatment takes place at BBERF, take place that interdepartmental system switches or UE when carrying out the pre-registration etc. of interdepartmental system such as UE, PCRF need control the BBERF that two or more are positioned at different system or network element simultaneously, one of them is called main BBERF (Primary BBERF), other be called non-main BBERF (Non-Primary BBERF).PCRF is respectively simultaneously for each BBERF preserves its QoS rule and state, and is also different to the operation of these BBERF.For example: when PCRF will upgrade the QoS rule, PCRF can be handed down to these BBERF simultaneously with the QoS rule of upgrading, if Primary BBERF can't successfully install the QoS rule, Primary BBERF reports PCRF with this situation, PCRF will delete QoS rule identical among the Non-Primary, and corresponding PCC rule among the deletion PCEF.If Non-Primary BBERF can't successfully install the QoS rule, after Non-Primary BBERF reported PCRF with this situation, PCRF just upgraded QoS rule and the state of preserving for Non-Primary BBERF among the PCRF thereof, and does not carry out other operation.Certainly, hPCRF also has other different operating at what Primary BBERF and Non-Primary BBERF carried out, repeats no more here.
Fig. 2 be in the prior art UE under non-roaming scene, close by E-UTRAN or trusted non-3 GPP access network, insert the flow chart of the IP-CAN session foundation of EPS, when supposing to insert by E-UTRAN, adopt the PMIPv6 agreement between S-GW and the P-GW, when closing access, adopt the PMIPv6 agreement between IAD and the P-GW by the trusted non-3 GPP access network.As shown in Figure 2, may further comprise the steps:
Step 201:BBERF receives and sets up the IP-CAN conversation request message, and the BBERF access information that obtained user ID such as network access Identifier (NAI, Network Access Identity), PDN sign and be used to generate strategy.Wherein, access information comprises BBERF place network of network sign, UE current position information, the address of BBERF and IP-CAN type or RAT type etc.
BBERF can be positioned at the S-GW or the trusted non-3 GPP access network Central Shanxi Plain.
Step 202:BBERF sends gateway control session to PCRF and sets up Indication message, sets up the access information that carries user ID, PDN sign in the Indication message, is used to generate strategy in gateway control session.
The Gxx session of being set up Indication message foundation by this gateway control session is called Gxx session 1.
Step 203:PCRF preserves the access information that reports.According to user ID, PDN sign, with the signatory document library (SPR of user, Subscription Profile Repository) mutual, obtain the CAMEL-Subscription-Information of UE, and formulate PCC rule, QoS rule and the event trigger of acquiescence according to network strategy and the access information that reports etc.PCRF sends gateway control session to BBERF and sets up acknowledge message, carries QoS rule and event trigger in the message, for BBERF QoS rule and event trigger is installed.
The gateway at step 204:BBERF place sends to P-GW and sets up the IP-CAN conversation request message, carries the NAI sign of UE in the message, PDN sign, and information such as the IP-CAN type of Access Network or RAT type.Setting up the IP-CAN conversation request message is agent binding update messages when realizing.
Here, step 204 can be carried out simultaneously with step 202, the message of needn't waiting step 203 returning.
Step 205:P-GW is UE distributing IP address, and the PCEF that resides at P-GW sends the IP-CAN session to PCRF and sets up Indication message, carries user ID in the message, is the access information that UE IP address allocated, PDN identify and be used to generate strategy.Here, the access information that is used for generating strategy is: IP-CAN type that step 204 reports or RAT type.The Gx session of setting up Indication message foundation by the IP-CAN session is called Gx session 1.
Step 206:PCRF carries out the Gxx session of setting up in Gx session 1 and the step 202 related according to user ID.PCC rule and event trigger that PCRF will formulate are before set up acknowledge message by the IP-CAN session and are sent to PCEF.Owing to have only a BBERF now, so this BBERF can think Primary BBERF.Certainly PCRF also can be consistent with the IP-CAN type that step 202 reports according to the IP-CAN type that step 205 reports, and judging BBERF is Primary BBERF.
After PCEF receives the confirmation message, the PCC rule and the event trigger that issue are installed, and PCRF can also revise and formulate good PCC rule according to the access information that is used to generate strategy that PCEF provides, so, PCRF issues the PCC rule of revising.
Step 207:P-GW returns to the gateway at BBERF place and sets up the IP-CAN session and reply.When realizing, set up the IP-CAN session and reply and be the agent binding update acknowledge message.Setting up the affirmation message that the IP-CAN session response message needn't waiting step 206 can initiate.
Step 208:BBERF place gateway returns to be set up the IP-CAN session and replys.
Fig. 3 closes by E-UTRAN or trusted non-3 GPP access network for existing UE, insert the flow chart of the IP-CAN session modification of EPS, after supposing to insert as shown in Figure 2 EPS and setting up the IP-CAN session, because gravity treatment takes place BBERF, switch or UE carries out interdepartmental system pre-registration and the IP-CAN session modification that causes such as UE.And hypothesis adopts the PMIPv6 agreement when inserting by E-UTRAN between S-GW and the P-GW, closes when inserting employing PMIPv6 agreement between IAD and the P-GW by the trusted non-3 GPP access network.As shown in Figure 3, may further comprise the steps:
Step 301: new BBERF (New BBERF) receives and sets up the gateway control session request message, and New BBERF has obtained user ID, PDN sign and the access information that is used to generate strategy etc., access information comprises the network identity of New BBERF, the UE current position information, the IP-CAN type of Access Network or IP-CAN type and RAT type etc.
Step 302:New BBERF sends gateway control session to PCRF and sets up Indication message, set up in this gateway control session and to carry user ID, PDN sign in the Indication message, and the access information that is used to generate strategy etc., access information comprises New BBERF place network of network sign, IP-CAN type or the IP-CAN type and the RAT type etc. of UE current position information, New BBERF address and new Access Network.The Gxx conversational list of setting up Indication message foundation by gateway control session is shown Gxx session 2.
Step 303:PCRF carries out related with Subsessionl Gxx session 2 according to user ID with the PDN sign.PCRF sends gateway control session to New BBERF and sets up acknowledge message, carries QoS rule, event trigger in this message.PCRF reformulates the QoS rule according to the new access information of UE.At this moment, PCRF can judge which BBERF is Primary BBERF, and which is Non-primary BBERF.If the Access Network IP-CAN Type-Inconsistencies that PCEF reports in the new Access Network IP-CAN type that New BBERF reports in the step 302 and Fig. 1 step 205, so, it is Non-Primary BBERF that PCRF judges New BBERF, and Old BBERF still is Primary BBERF.
From this moment, PCRF will carry out the different operating at Primary BBERF and Non-Primary BBERF.The flow process that UE carries out interdepartmental system pre-registration leaves it at that, and the flow process that UE switches continues following steps.
The gateway at step 304:New BBERF place sends IP-CAN session signaling message to P-GW, carries user ID and PDN sign in this message.This message is the agent binding update messages of PMIPv6 when realizing.Carry new Access Network IP-CAN type or IP-CAN type and RAT type in the message.
PCEF among the step 305:P-GW judges UE according to information such as user ID, PDN signs switching has taken place, and find UE switch before corresponding context, that is: information such as PCC rule, event trigger, send IP-CAN session modification Indication message by Gx session 1 to PCRF then, carry the access information after UE switches in this message, comprise new Access Network IP-CAN type or IP-CAN type and RAT type.
The Access Network information that the access information that step 306:PCRF reports according to Gx session 1 and Gxx session 1, Gxx session 2 report respectively judges that decision New BBERF is Primary BBERF, and OldBBERF is Non-Primary BBERF.The new Access Network IP-CAN type that PCEF reports in the step 306, the new Access Network IP-CAN type that reports with New BBERF in the step 302 is consistent, therefore, it is Primary BBERF that PCRF judges New BBERF, and Old BBERF is Non-PrimaryBBERF.The access information that PCRF reports according to New BBERF, user contracting data, network strategy etc. are reformulated PCC rule, QoS rule and event trigger.PCRF returns IP-CAN session modification acknowledge message to PCEF, wherein carries the PCC rule and the event trigger of renewal.
Step 307:P-GW returns IP-CAN session signaling message to New BBERF place gateway, and this message is the agent binding update acknowledge message when realizing.
Step 308:New BBERF place gateway returns the gateway control session response message.
QoS after step 309:PCRF will upgrade rule and event trigger pass through Gxx session 2, and are carried at gateway control and QoS rule and send to New BBERF in giving information.
Step 310:New BBERF installs and also to carry out QoS rule and event trigger, and returns gateway control and the QoS rule provides acknowledge message to PCRF.
PCRF also can be to QoS rule and the event trigger after Old BBERF sends renewal, and PCR F sends to OldBBERF by Gxx session 1 with Qos rule and event trigger with QoS rule, event trigger.
In sum, in the process that the BBERF gravity treatment takes place, PCRF has controlled 2 BBERF simultaneously, and according to the classification of BBERF, carries out policy control such as Primary and Non-Primary.Prior art has only disclosed at PCRF and has controlled simultaneously under the scene of 2 BBERF, sets up gateway control session processing of request flow process, does not disclose for the handling process of the follow-up gateway control session termination Indication message that sends at one of them BBERF.Especially, control simultaneously at PCRF under the scene of 2 above BBERF, how PCRF handles still an open question after receiving the gateway control session termination Indication message of one of them BBERF transmission.
