Description
Technical field
The present invention relates to moving communicating field, relate in particular to a kind of method for building up and device of strategy session.
Background technology
Third generation partner program (3rd Generation Partnership Project, the grouping system of evolution 3GPP) (Evolved Packet System, EPS) by Universal Terrestrial Radio Access Network (the Evolved Universal Terrestrial Radio Access Network of evolution, E-UTRAN), mobile management unit (Mobility Management Entity, MME), gateway (Serving Gateway, S-GW), grouped data network gateway (Packet Data Network Gateway, P-GW) and home subscriber server (Home Subscriber Server HSS) forms.
EPS supports the intercommunication (as shown in Figure 1) 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 inserts and is divided into trustless non-3GPP access and the non-3GPP access of trusted; Wherein, (Evolved Packet Data Gateway's packet data gateway of trustless non-3GPP access need process evolution ePDG) links to each other with P-GW, and the interface between ePDG and P-GW is S2b; The non-3GPP of trusted inserts and can directly be connected with P-GW by the S2a interface, and the S2a interface adopts PMIPv6 (Proxy Mobile IP version 6, proxy mobile IP protocol version 6) agreement to carry out information interaction; In addition, the S2c interface provides subscriber equipment (User Equipment, UE) with P-GW between relevant control and the mobility support of user's face, the mobility management protocol of its support is for supporting mobile IP v 6 (the Mobile IPv6Support for Dual Stack Hosts and Routers of two stacks, DSMIPv6), it can be used for trustless non-3GPP and the non-3GPP access of trusted.
WLAN (Wireless Local Area Network, WLAN) can be used as non-3 GPP system, (the S2a pattern just under study for action to insert EPC with above-mentioned S2b pattern or S2c pattern, wouldn't belong to research object of the present invention), this relates to technology (Fixed Mobile Convergence, the FMC) problem of interconnection and interflow and the fusion of fixed network, mobile network.Wherein, interconnect and the technology introduction of the network integration as follows:
1) WLAN inserts and the offload technology
(evolved Packet Core is in the time of EPC), as shown in Figure 2 when terminal inserts evolution block core net by WLAN.It is the local address (UE local IP address) of the UE of its distribution that UE at first obtains wlan network (perhaps being called fixed network, BBF network, BBF access network, WIFI networking etc.).
Terminal UE connects with the PDN that this local ip address is established to EPC, and P-GW also can distribute an IP address for terminal UE.Wherein, the EPC IP address allocated of terminal is used for communicating by letter with extraneous by P-GW, during data process wlan network, also uses local ip address packet is carried out data encapsulation again one time, this part business datum is called the EPC-routed business datum, as passing through among the figure shown in the P-GW dotted line.Simultaneously, terminal also can directly be communicated by letter with extraneous by local ip address, this part business datum is called shunting " offload " business datum, as among the figure directly from BNG/BRAS (Broadband network gateway/Broadband Remote Access Server, wideband network gateway/Broadband Remote Access Server) directly shown in the arrow of directed outwards network.
Be that RG in the existing network (Residential Gateway, home gateway) has two kinds of mode of operations: route pattern and bridge mode to what above-mentioned UE local ip address need replenish.When network RG was operated in bridge mode, the IP address that UE obtains when inserting wlan network was exactly the local ip address of UE; When RG is operated in route pattern, there is NA (P) T (Network Address (Port) Translation on the RG, NA (P) T), UE is its distribution from the address that WLAN obtains by RG, this address is privately owned address, but the local address that the corresponding RG in this address obtains from wlan network adds a port numbers, the local address of this RG adds port numbers and sets up the PDN connection for terminal UE to EPC, and this local address adds the access that port numbers can be located this UE, some the time also be called for short the local ip address of UE, be actually local ip address and the port numbers (if can get) that be called UE, the person skilled in art should be understood that, so long as under the situation of ports having number, this port numbers can be sent to EPC.
Also need to prove, owing to do under the scene of router at RG, if terminal is from the directly external intercommunication data (being offload) of BNG/BRAS, network side can only perception RG rather than the direct UE below the perception RG, therefore can not guarantee the service quality QoS of terminal under this kind scene, that is to say that RG does under the router scene, to the business datum of offload guaranteed qos not, need not policy control.
2) Home eNodeB (Home (evolved) Node B, H (e) NB) access technology
H (e) NB technology not do not show that in the drawings at this it is done simple introduction, H (e) NB is by WLAN, perhaps is called fixed network network insertion EPC, inserts the data of UE of H (e) NB through the WLAN/ fixed network network carrying.Therefore be similar to the WLAN access technology, have a same term " local ip address of H (e) NB and port numbers (if can get) ", this address and port numbers (if can get) also can be located the access of current H (e) NB/ terminal UE.
This paper all refers to or the Home eNodeB HeNB of the evolution of EPC system when using title " Home eNodeB ", or 3G (3
RdGeneration, 3G (Third Generation) Moblie) the Home eNodeB HNB in the system.
3) tactful intercommunication and integration technology
No matter be to insert or insert from H (e) NB from WLAN, no matter business datum is directly to shunt (offload) to external network from BNG/BRAS, still be routed to EPC and be routed to external network by P-GW, the employed business datum of terminal UE all can take the resource of wlan network.Therefore in order to guarantee the QoS of business datum in transmission course, in the existing technology, (Policy Control and Rule Function PCRF) and between the broadband policy controlled entity BPCF of wlan network (Broadband Policy Control Function) has designed S9a (original name S9 at the policy control of EPC network and regulation function entity
*, the existing S9a that renamed) and interface, for the strategy of transmission intercommunication.
Wherein, for the business datum by H (e) NB system transmissions, with by WLAN and via the business datum of EPC route, set up " gateway control session (Gateway Control Session) " at the S9a interface, be that the QoS of business datum guarantees the intercommunication strategy; Be routed directly to the business datum of external network for the BNG/BRAS from wlan network, having set up IP at the S9a interface, to connect Access Network (IP-CAN, IP Connectivity Access Network) session be that the QoS of business datum guarantees the intercommunication strategy.Referring to Fig. 3.
3 in accompanying drawing based on scene be, terminal UE inserts EPC by wlan network and sets up PDN and connect (wlan network is not supported under the scene of authentication of 3GPP), perhaps terminal UE is linked into EPC by H (e) NB and sets up PDN and connects, P-GW and PCRF have set up the strategy session of Gx interface, after PCRF had received the local ip address and port numbers (if can get) or H (e) NB local ip address and port numbers (if can get) of UE from P-GW, PCRF initiated gateway control session foundation operation to the BPCF of wlan network by the S9a interface.
Step 301:PCRF sets up operation to the gateway control session that BPCF initiates on the S9a interface, and UE local address and port numbers (if can get) information have been sent to BPCF.Concrete operations are, PCRF sends to BPCF and triggers (trigger), and BPCF sends request (request) to PCRF, and PCRF responds response (response) to BPCF.Wherein this gateway control session is " through the business datum service of EPC route ".
Step 302: be subjected to the triggering of step 301, BPCF sets up operation to the IP-CAN session that this PCRF or other PCRF (the selection mechanism that depends on PCRF) in the EPC territory initiate on the S9a interface.Be specially, BPCF sends request (request) to PCRF, and PCRF responds response (response) to BPCF.Wherein this IP-CAN session is the business datum service of WLAN shunting (offload).
In the above-mentioned background technology, have three seed scenes: 1) terminal UE is linked into EPC by WLAN, has NA (P) T on the RG in the wlan network; 2) terminal UE is linked into EPC by WLAN, does not have NA (P) T on the RG in the wlan network; 3) terminal UE is linked into EPC by H (e) NB.After having carried out the process step of Fig. 3 under these three kinds of scenes, can set up an IP-CAN session between BPCF and the PCRF.When there is NA (P) T in WLAN, the UE of a plurality of access WLAN can share same local ip address (the publicly-owned address of RG), therefore to a plurality of UE under the same RG, finally just may set up a plurality of IP-CAN sessions, like this, as the AF of application layer (application function, when application function) downloading related service information, DRA (diameter routing agent in the existing EPC territory, diameter route agent) (DRA can only look for PCRF based on the address just to can not find correct PCRF, can not look for PCRF by port numbers), the session association mistake will appear like this.
