Description
Technical field
The present invention relates to tactful integration technology, relate in particular to business access method and tactful emerging system in a kind of network element strategy UNE.
Background technology
Third generation partner program (3GPP, 3rd Generation Partnership Project) grouping system (EPS of evolution, Evolved Packet System) by the universal mobile telecommunications system 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), grouped data network gateway (P-GW or PDN GW, Packet Data NetworkGateway), home subscriber server (HSS, Home Subscriber Server), "Policy and Charging Rules Function (PCRF, Policy and Charging Rules Function) entity and other support nodes are formed.
Fig. 1 is the composition structural representation of EPS system architecture, as shown in Figure 1, the PCRF entity links to each other by receiving interface Rx and operator's Internet protocol (IP, Internet Protocol) business network, obtains business information, in addition, the PCRF entity also 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 of assurance business datum, and the control of chargeing Quality of Service).
Access network discovery and selection function (ANDSF, Access NetworkDiscovery and Selection Function) entity has been proposed in the EPS system.The ANDSF entity comprises data management and controlled function, and its effect is to provide network to find and the selection auxiliary data according to carrier policy.The ANDSF entity provides two kinds of information, is respectively shift strategy information and access network discovery information between communication system.According to the demand of operator, the ANDSF entity can provide two kinds or any information wherein simultaneously.
Fig. 2 is the application structure schematic diagram of ANDSF entity, as shown in Figure 2, when user terminal (UserEquipment) inserts the EPS system by the 3GPP/ non-3 GPP access network, need be linked in the ANDSF entity by the S14 interface, the UE under the non-3 GPP access network particularly, the ANDSF entity is required to be it and selects corresponding access protocol, just can be linked into the EPS system.The ANDSF entity is supported PULL and PUSH pattern, and wherein, the PULL pattern is that UE carries out the active application to network, triggers the ANDSF entity and sends the network information to UE.And the PUSH pattern mainly is initiatively to be triggered to UE by network to send data.Wherein the PUSH pattern is optional.
The IP mobile management is selected (IPMS, IP Mobility management Selection) mainly to be based on UE ability and network capabilities and is decided IP protocol type.That mainly select is S2a in the EPS system, S2b, and the S2c interface protocol, irrelevant with the GTP/PMIP selection in the S5/S8 interface.
Fig. 3 is the application structure schematic diagram of IPMS entity, as shown in Figure 3, UE inserts HSS/AAA (Authentication, Authorization, Accounting) by gateway, wherein, gateway may be grouped data network gateway (P-GW), also may decide on different scenes for gateway (S-GW).UE sends its network capabilities to HSS/AAA when the authentication, and network also sends its ability to HSS/AAA.By HSS/AAA decision IP protocol type.Then its negotiation result is returned to gateway, initiate IP by respective gateway and connect.In the EPS system, there is not an independent network element in the IPMS entity, but closes the logical block that is located at AAA at present.
In the EPS system, PCRF entity, ANDSF entity and IPMS entity all are the tactic network elements, and all being externally provides strategy to support.At present, the strategy that each network element externally provides all is separate, provides based on the policy control decision-making with based on the strategy of the charging control of stream such as: PCRF entity.The ANDSF entity provides the access network policy based on UE.The IPMS entity provides the IP protocol type based on UE ability and network capabilities.Under multi-network environment, data fusion is the inexorable trend of network development.User data merges the problem that theory that (UDC, User Data Convergency) just be based on data fusion is studied in 3GPP R9.Fig. 4 is that the system architecture of UDC is formed schematic diagram, and as shown in Figure 4, UDC supports layer architecture, data processing is separated with applied logic, and the user data that is stored among the UDR can be employed front end (FE, Front End) visit, wherein, FE is core layer and operation layer entity.
