Background technology
Grouping system (the Evolved Packet System of 3GPP evolution, referred to as EPS) by universal mobile telecommunications system land radio access web (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 (ServingGateway, referred to as S-GW), grouped data network gateway (Packet Data Network Gateway, referred to as P-GW or PDN GW), home subscriber server (Home Subscriber Server, referred to as HSS), "Policy and Charging Rules Function (Policy and Charging Rules Function, referred to as PCRF) entity and other support nodes composition.
Increasingly mature and universal along with WLAN access technology, and user is to the demand of High-speed wireless access, domestic and overseas operators is all greatly developing WLAN business.WLAN business, as the shunting means of cellular data network, acts on more and more important.
3GPP from Rel-11 begin one's study support WLAN as trust access network be the connection that subscriber equipment is provided to EPC.In the Rel-11 stage, mainly study the scheme on subscriber equipment impact useless, subscriber equipment can only be set up wall scroll grouped data by wlan network and connect, and does not support that subscriber equipment carries out the switching of grouped data connection between WLAN Access Network and 3GPP Access Network.This data cube computation can be connect to the grouped data of EPC, also can be the NSWO(Non-seamless WLAN offload directly linking data network from wlan network) connect.
At present, the WLAN access EPC network that 3GPP is carrying out Rel-12 trust has the research affecting scheme on subscriber equipment, real needs comprise:
1) scheme of compatible R11SaMOG;
2) flow processs such as multi-packet data network (Packet Data Network, PDN) connection, switching are supported;
3) support to transmit the information such as access point (Access Point Name, referred to as APN), PDN type;
4) scene simultaneously being accessed EPC and WLAN service distributing by WLAN is supported.
Whether UE can indicate it to support to access EPC or NSWO to network side, and network side also can indicate the result of access EPC or NSWO of decision-making to UE.
Fig. 1 is the Organization Chart being linked into EPC network design according to the WLAN of the trust of correlation technique, and as shown in Figure 1, subscriber equipment is connected to EPC by the WLAN access network (Trusted WLAN access network, referred to as TWAN) of trusting.TWAN supports the S2a GTP/PMIPv6 interface of PDN GW.UE is connected to the flow process of TWAN inside not in 3GPP research range.But 3GPP defines the main functional modules of the TWAN of composition.
