Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of method for releasing of resource, the processing method of message, credit WLAN (wireless local area network) IAD (TWAG) and terminal.
Background technology
Third generation partner program (3rd Generation Partnership Project, referred to as 3GPP) grouping system (the Evolved Packet System of evolution, referred to as EPS) by Universal Terrestrial Radio Access Network (the Evolved Universal Terrestrial Radio Access Network of evolution, referred to as E-UTRAN), mobile management unit (Mobility Management Entity, referred to as MME), gateway (Serving Gateway, referred to as S-GW), grouped data network gateway (Packet Data Network Gateway, referred to as PDN GW) and home subscriber server (Home Subscriber Server, referred to as HSS) form.
Fig. 1 is the schematic network structure of existing 3GPP network and non-3GPP network interworking, as shown in Figure 1, EPS supports the intercommunication with non-3 GPP system, wherein, by S2a/b/c Interface realization, PDN GW is as the anchor point between 3GPP and non-3 GPP system with the intercommunication of non-3 GPP system.In the system architecture diagram of EPS, non-3 GPP system access is divided into trustless non-3GPP access and the non-3GPP access of trusted; Wherein, trustless non-3GPP access needs to be connected with PDN GW through the packet data gateway (Evolved Packet Data Gateway, referred to as ePDG) of evolution, and the interface between ePDG and PDN GW is S2b; The non-3GPP access of trusted can directly be connected with PDN GW by S2a interface, and S2a interface adopts proxy-mobile IP (PMIP) agreement to carry out information interaction; In addition, S2c interface provides subscriber equipment (User Equipment, referred to as UE) control and the mobility support relevant to user's face between PDN GW, the mobility management protocol of its support is for supporting mobile IP v 6 (the Moblie IPv6Support for Dual Stack Hosts and Routers of two stacks, referred to as DSMIPv6), it can be used for trustless non-3GPP and the non-3GPP access of trusted.
WLAN (wireless local area network) (Wireless Local Area Network, referred to as WLAN) can be used as packet-based core networks (the Evolved Packet Core of non-3 GPP system access evolution, referred to as EPC), this relates to the interconnection and interflow problem of the fixed network mobile fusion of a lot of operators concern.
At present, a lot of for S2b, the flow process of S2c interface and the research of tactful intercommunication, and for the research of S2a interface seldom.S2a Research of Mobility (Study on S2a Mobility based On GTP & WLAN access to EPC, referred to as SaMOG) problem be mainly research WLAN as non-3 GPP access network network trusty (trusted non-3GPP IP access network, referred to as TNAN), UE is by the interconnection and interflow problem of S2a interface access EPC.
In addition, universal mobile telecommunications system (Universal Mobile Telecommunications System, referred to as UMTS) is also supported the intercommunication with non-3 GPP system; Different is, use service universal packet wireless business business support node (Serving General Packet Radio Service Support Node, referred to as SGSN) replaced MME and S-GW, use ggsn (Gateway General Packet Radio Service Supporting Node, referred to as GGSN) to replace P-GW.
According to actual network design situation, access controller (Access Controller, referred to as AC)/wideband network gateway (Broadband Network Gateway, referred to as BNG) may follow credit WLAN IAD (Trusted WLAN Access Gateway, referred to as TWAG) close and establish deployment, also may set up separately.Fig. 2 is existing AC/BNG and the schematic network structure of the separated setting of TWAG, as shown in Figure 2, the network architecture that AC/BNG and TWAG set up separately is that terminal is connected to above AC/BNG by access point, then by TWAG, be linked into the PDN-GW in 3GPP core net, thereby use the business of 3GPP, and this part terminal is accessed to needed access authentication process, need successively by TWAG and WLAN authentication, authorize and accounting server (Authentication Authorization and Accounting, referred to as AAA) to the AAA/HSS server of 3GPP core net, carry out.
In 3GPP prior art, a terminal may be set up multilink, but is all separate for the release of each link, and traditional wlan network is only supported foundation and the release of a link.When accessing 3GPP core net by WLAN, WLAN Access Network also needs to be expanded and supports to set up multilink, and in order to distinguish the DynamicHost of a plurality of links in terminal, agreement (DHCP) message is set, except terminal iidentification, also need another one sign, for example PDN connection identifier or VLAN (VLAN) identify, and these all complete and association in link establishment process.How discharging efficiently wherein one, many and whole link, not yet propose effective solution at present.Therefore, the problems referred to above exist too accessing other networks such as UMTS core net by non-3 GPP system.
