Abstract

The invention discloses a method and a system for establishing a session. After an evolved packet data gateway (ePDG) establishes a Gxb session for a visiting policy and charging rules function (V-PCRF), the V-PCRF judges whether an S9 session is required to be established for a home (H)-PCRF according to the type of a protocol which is used by an S2b interface or according to using or not of the ePDG as a bearer binding and event report function (BBERF), so that the problem of influence on a processing mechanism of the H-PCRF caused by establishment of the S9 session when the V-PCRF senses access of user equipment (UE) in an S2b-general packet radio service (GPRS) tunneling protocol (GTP) on the premise of no consideration of the protocol which is used by the S2b interface can be solved. The invention also discloses a method and a system for issuing a policy. After the ePDG establishes the Gxb session for a PCRF, the PCRF judges whether a policy and charging control (PCC) policy is issued to the ePDG according to the type of the protocol which is used by the S2b interface or according to using or not of the ePDG as the BBERF, so that a dynamic policy can be performed on the ePDG, and the quality of service (QoS) control of a service data stream is better realized.

Description

A kind of method and system of setting up session, policy distribution
Technical field
The present invention relates to moving communicating field, be meant a kind of method and system of setting up session, policy distribution especially.
Background technology
Third generation partner program (3GPP; 3rd Generation Partnership Project) grouping system (EPS of evolution; Evolved Packet System) by the UMTS land radio access web (E-UTRAN of evolution; Evolved Universal Terrestrial Radio Access Network), mobile management unit (MME; Mobility Management Entity), gateway (S-GW; ServingGateway), the authentication and authorization charging (AAA of grouped data network gateway (Packet Data Network Gateway abbreviates P-GW or PDN GW as), home subscriber server (HSS, Home Subscriber Server), 3GPP; Authentication, Authorization and Accounting) server, "Policy and Charging Rules Function (PCRF, Policy and Charging Rules Function) entity and other support nodes form.
Fig. 1 is the sketch map according to the system architecture of the EPS of correlation technique, and wherein, MME is responsible for the related work of chains of command such as processing and the contextual management of user's mobile management of mobile management, Non-Access Stratum signaling; S-GW is the accessing gateway equipment that links to each other with E-UTRAN, between E-UTRAN and P-GW, transmits data, and is responsible for pending datas such as paging are carried out buffer memory; P-GW then is the borde gateway of EPS and packet data network (PDN, Packet Data Network) network, and the access of being responsible for PDN reaches functions such as between EPS and PDN, transmitting data; S-GW and P-GW belong to the core net gateway; PCRF links to each other through receiving interface Rx and carrier network agreement (IP, Internet Protocol) business network, obtains business information; In addition; It links to each other with gateway device in the network through the Gx/Gxa/Gxc interface, is responsible for initiating the foundation that IP carries, the service quality (QoS of assurance business datum; And the control of chargeing Quality of Service).
EPS supports the intercommunication with non-3 GPP system, wherein, passes through the S2a/b/c interface with the intercommunication of non-3 GPP system and realizes that P-GW is as the anchor point between 3GPP and non-3 GPP system.In the system architecture diagram of EPS, non-3 GPP system is divided into the non-3GPP IP access of trusted and trustless non-3GPP IP inserts.The non-3GPP IP of trusted inserts and can directly be connected with P-GW through the S2a interface; Trustless non-3GPP IP inserts the packet 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; S2c provides subscriber equipment (UE; User Equipment) with P-GW between relevant control and the mobility support of user plane; The mobility management protocol of its support is for supporting the mobile IP v 6 (DSMIPv6, Moblie IPv6 Support for Dual Stack Hosts andRouters) of two stacks.
Among the EPS system, strategy and charge execution function (PCEF, Policy and ChargingEnforcement Function) entity are present among the P-GW, pass through Gx interface (see figure 1) exchange message between PCRF and the P-GW.Interface S5 when between P-GW and S-GW is based on PMIPv6 (Proxy MobileIPv6; Proxy mobile IP protocol version 6) time; S-GW also has bearing binding and event reporting function (BBERF; Bearer Binding and Event Report Function) entity carries out QoS control to business data flow, passes through Gxc interface (see figure 1) exchange message between S-GW and the PCRF.When inserting through the non-3GPP connecting system of trusted, the also resident BBERF in the trusted non-3 GPP access network Central Shanxi Plain.Pass through Gxa interface (see figure 1) exchange message between trusted non-3 GPP access network pass and the PCRF.When UE roams; The S9 interface is as the interface between ownership place PCRF and the visit ground PCRF; For UE provides service application function (AF; Application Function), UE sends to PCRF through Rx interface and is used to generate strategy and business information that the control of chargeing (PCC, Policy and Charging Control) is tactful.In 3GPP, can find corresponding PDN network through APN (APN, Access Point Name).Usually UE is called an IP connection access network (IP-CAN, IP Connectivity Access Network) session to a connection of PDN network.In the process of setting up the IP-CAN session, BBERF and PCEF respectively and set up the Diameter session between the PCRF transmit the policy, billing information that this IP-CAN session is controlled and the information that is used to generate strategy etc. through these Diameter sessions.
Broadband forum (BBF, Broadband Forum) has proposed the broadband policy controlled function (BPCF, Broadband Policy Control Function) of broadband policy control architecture, and is as shown in Figure 2, and the BPCF major function is to formulate corresponding strategy; Policy Enforcement Point (PEP; Policy Enforcement Point) resides in usually in the fixed network transmission equipment; For example: BAS Broadband Access Server (BRAS; Broadband RemoteAccess Server)/and broadband networks gateway (BNG, Broadband Network Gateway), carry out the corresponding strategy that BPCF formulates; AAA stored user CAMEL-Subscription-Information; AF is that BPCF generates strategy, and corresponding business information is provided.The framework of BPCF is also relatively more rough at present, and correlative detail is also in further formulating.
Now the fixed network paid close attention to very much of operator moves fusion (FMC, Fixed Mobile Convergence) scene, and just being based on interconnects to 3GPP and BBF studies.For the scene of user, be to guarantee that to the QoS on the routed path (data can be passed through fixed network and mobile network transmission) of whole data present stage is adopted S9 through BBF fixed network access mobile core net *(between PCRF and the BPCF) interface mode carries out.Mobile operator enlarges wireless covering for better operation is professional, considers from the angle of practicing thrift cost, can remove to rent the circuit of one section WLAN access of fixed network operator; UE inserts through the WLAN of fixed network; Because the transmission of these data can be passed through fixed network; When mobile operator can be regarded as fly-by-night network with the fixed network operator, UE meeting and ePDG set up IP Sec (IP safety) tunnel, and be as shown in Figure 3; Guarantee that like this UE is encrypted to the data of the transmission between the ePDG, the fixed network transmission equipment can't be learnt the content of transmission.According to the deployment scenario of actual fixed network network, the perception of fixed network possibility is less than mobile subscriber's access, for example: when the user inserted through home gateway (RG, Residential Gateway), RG had shielded user's access.For this scene, ePDG need inform that the access information (for example: IP-sec tunnel information and/or UE fixed network insert information such as ID) of UE pass through S9 by PCRF again by PCRF *Inform BPCF, BPCF does according to the access information of UE and admits control, guarantees the QoS of data in the fixed network transmission; Follow-up discussion just is based on the situation that fixed network can't perception UE inserts.
Above-mentioned discussion is under the non-roaming scene of FMC; For also being what need to consider under the roaming scence; For example: the user of China Mobile comes Britain, because Britain Vodafone operator and China Mobile have roaming agreement to guarantee that the user of China Mobile can roam in Britain; Simultaneously, between Vodafone and the Britain Telecom (BT, Britain Telecom) the FMC agreement is arranged, allow the user of China Mobile to be linked into the mobile network of Vodafone through the fixed network (for example WLAN WLAN) of BT this moment.
Path according to roaming scence data route is different, and roaming scence is divided into Home Routed and 2 kinds of modes of LocalBreakout, shown in Figure 4 and 5.Under the Home Routed roaming scence, data are gone out from the P-GW of ownership place; And under the Local Breakout roaming scence, data can be gone out (under the situation of permission, compare Home Routed, can reduce the circuitous consumption of data route) by the direct route of P-GW on visit ground.
For S2b interface (between ePDG and the P-GW), there are two types of optional agreements at present, one type is PMIP and DSMIP agreement; One type is GPRS Tunnel Protocol (GTP) agreement, in the existing scheme:
Scene for S2b-PMIP/DSMIP; EPDG serves as the role of BBERF; EPDG can set up the Gxb session to visit ground PCRF (V-PCRF), and (this session is to transmit data through the Gxb interface; Abbreviate the Gxb session as), ePDG can pass to V-PCRF through Gxb with user's access information, and then can trigger V-PCRF and set up S9 to BPCF *(interface) session and set up the S9 session to ownership place PCRF (H-PCRF).
But for the scene of S2b-GTP, according to the characteristics of GTP agreement, can not serve as ePDG at this moment the role of BBERF, ePDG and V-PCRF do not have Gxb session (shown in Fig. 6 and 7), and ePDG can't pass to V-PCRF with user's access information through the Gxb interface; Further, under Home Routed roaming scence, V-PCRF under the triggering that does not have the Gxb session, be can't perception UE access, can not trigger V-PCRF and set up S9 to BPCF *Session is like Fig. 6; But under the Local Breakout roaming scence, even without Gxb session, S9 *The foundation of session still can trigger V-PCRF through the Gx interface by P-GW, like Fig. 7.
For the problem that above-mentioned different roaming scence brings, the someone proposes ePDG and can not consider when V-PCRF sets up the Gxb session to that is to say protocol type that even under the S2b-GTP scene, ePDG also can set up the Gxb session to V-PCRF.EPDG can carry user accessing information through the Gxb interface like this, and V-PCRF receives triggering simultaneously, and perception UE inserts, and sets up S9 to BPCF *Session.
If according to above-mentioned scheme, can bring new problem again, existing S9 mechanism: after V-PCRF receives the message from ePDG, can be triggered and set up the S9 session to H-PCRF; For the S2b-PMIP scene; The foundation of S9 session is (this moment, ePDG was as BBERF) that is necessary; And for the scene of S2b-GTP, the foundation of S9 session is (ePDG is not as BBERF) unnecessary, but also can existing H-PCRF treatment mechanism be exerted an influence; How can under the situation that does not influence the H-PCRF treatment mechanism, address this problem, be the emphasis of studying of the present invention.
In addition, for non-roaming scene, in the present technology; The qos policy that ePDG carries out is static; The mode that is operator through disposing (for example: through the gateway configuration platform, configuring static strategy when ePDG powers on) realize, therefore accurate inadequately for the control of data flow.If can on ePDG, carry out dynamic strategy (for example :), can better realize QoS control to business data flow from the dynamic strategy of PCRF formulation.
Summary of the invention
In view of this; Main purpose of the present invention is to provide a kind of method and system of setting up session; Can solve under the scene of not considering the employed protocol type of S2b interface; When V-PCRF perceives the access of UE under the S2b-GTP scene, because the problem that the H-PCRF treatment mechanism is exerted an influence that the foundation of S9 session causes;

Embodiment
Below in conjunction with accompanying drawing and specific embodiment technical scheme of the present invention is further set forth in detail.
The main thought that the present invention sets up session is: under roaming scence; EPDG does not consider protocol type that the S2b interface uses, does not consider that whether ePDG is as BBERF when V-PCRF sets up the Gxb session; But after the Gxb session, whether determine whether to set up the S9 session to H-PCRF as BBERF according to the protocol type or the ePDG that just use according to the S2b interface; Specifically as shown in Figure 8, comprising:
Step 801, ePDG sets up the Gxb session to V-PCRF, and whether V-PCRF obtains protocol type that the S2b interface uses or ePDG as BBERF through the Gxb interface;
Step 802, whether V-PCRF judges whether and need set up the S9 session to H-PCRF as BBERF according to protocol type or the ePDG that the S2b interface uses.
Through concrete embodiment technique scheme is described below.
Embodiment one
The flow process of setting up session under the roaming scence of the present invention is as shown in Figure 9, comprising:
Step 901～902; When UE inserts visit ground mobile network through fixed network; If fixed network can perceive the access of UE, then visit the access authentication of ground mobile network, then the 3GPPAAA server of the BRAS/BNG of fixed network, BBF AAA agency (Proxy) and ownership place mobile network is participated in this verification process; This verification process specifically be embodied as prior art, repeat no more here.After authentication is accomplished, execution in step 902, BRAS/BNG is UE distributing IP address, execution in step 904 then.
If fixed network can't perceive the access of UE, then skips steps 901,902, and execution in step 903 is in execution in step 904.
Step 903, when UE inserted visit ground mobile network through fixed network, the RG of fixed network was not to UE distributing IP address (need carry out above-mentioned verification process).
Step 904, after UE obtained the IP address, UE and ePDG set up the IP secure tunnel; Simultaneously; EPDG is to the authentication and authorization of the 3GPP of ownership place mobile network aaa server request UE, and in authentication and authorization, the IP address that the 3GPP aaa server will be visited the P-GW of ground mobile network returns to ePDG; So ePDG connects according to this IP address and P-GW, just can confirm S2b interface use between ePDG and the P-GW protocol type, promptly can confirm whether ePDG can be used as BBERF.
Step 905, ePDG sets up the Gxb session to V-PCRF, and the foundation of this session is exactly for user accessing information is informed V-PCRF, and is concrete, user accessing information is carried in the message sends to V-PCRF through the Gxb interface; Simultaneously, whether V-PCRF obtains protocol type that the S2b interface between ePDG and the P-GW uses or ePDG as BBERF through the Gxb interface.
Wherein, whether V-PCRF obtains protocol type that the S2b interface uses or ePDG through the Gxb interface has as the mode of BBERF: display mode and implicit expression mode, wherein,
Display mode is: ePDG has sign or indication through the Gxb interface in the above-mentioned message that V-PCRF sends; Through this sign or indication; Whether protocol type that the S2b interface is used or ePDG inform that as BBERF (ePDG serves as BBERF to V-PCRF, and then the protocol type that uses of S2b is PMIP or DSMIP; EPDG does not serve as BBERF, and then the protocol type that uses of S2b is GTP);
The implicit expression mode is: V-PCRF is according to IP address and/or Hostname and/or the full name domain name (FQDN of the ePDG that carries in the above-mentioned message of receiving; Fully Qualified Domain Name) information; Whether the protocol type or this ePDG that obtain the use of S2b interface serve as BBERF; Concrete; Preserved an allocation list among the V-PCRF, can from this allocation list, find protocol type or this ePDG that corresponding S2b interface uses according to the IP address of ePDG and/or Hostname and/or FQDN information and whether serve as BBERF; Perhaps; V-PCRF generates a request message according to the IP address of ePDG and/or Hostname and/or FQDN information, to DNS or other preserve above-mentioned allocation list the server requests inquiry, obtain protocol type or this ePDG that corresponding S2b interface uses and whether serve as BBERF.
Above-mentioned ePDG informs V-PCRF to the message that V-PCRF sends with user accessing information, and so V-PCRF has just perceived the access of UE.
Step 906, V-PCRF judges whether to set up the S9 session to the H-PCRF of ownership place mobile network.
