Abstract
The invention discloses a mobile communication system and a method for relocation of service gateway thereof. The method is used for solving the problem that the relocation of the service gateway (SGW) cannot be realized in the presence of IP (Internet Protocol) traffic offload business. In the method, when the IP traffic offload connection is established or the position is updated, if the service gateway needs to be relocated, a mobility management entity needs to perform the following steps of: initiating load establishment to a target service gateway by the mobility management entity; initiating load update to an access gateway by the target service gateway; and sending the target service gateway information to a wireless side network element by the mobility management entity, wherein the execution sequence of the above steps is not limited. The method is suitable for relocation of the service gateway when the IP traffic offload connection is established or the position is updated. Under IP traffic offload, the accurate and timely switching of the service gateway can be realized.
Description
Technical field
The present invention relates to the mobile communication technology field, in particular to the method for a kind of GSM and gateway reorientation thereof.
Background technology
Third generation partner program (3rd Generation Partnership Project; Abbreviate 3GPP as) grouping system (the Evolved Packet System of evolution; Abbreviate EPS as) by UMTS land radio access web (the Evolved Universal Terrestrial Radio Access Network of evolution; Abbreviate E-UTRAN as), mobile management unit (Mobility Management Entity; Abbreviate MME as), gateway (Serving Gateway, S-GW), grouped data network gateway (Packet Data Network Gateway abbreviates P-GW or PDN GW as), home subscriber server (Home Subscriber Server; Abbreviate HSS as), authentication and authorization charging (Authentication, the Authorization and Accounting of 3GPP; Abbreviate AAA as) server, "Policy and Charging Rules Function (Policy and Charging Rules Function abbreviates PCRF as) entity and other support nodes are formed.
Fig. 1 is the sketch map according to the EPS system architecture of correlation technique, and is as shown in Figure 1, and Mobility Management Entity 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 (Packet Data Network abbreviates PDN as) 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.
Base station from home is a kind of small-sized, lower powered base station; Be deployed in indoor places such as family and office; Main effect is in order higher service rate to be provided to the user and to reduce and use the needed expense of high rate services, remedying the deficiency that existing distributed cellular radio communication system covers simultaneously.The advantage of base station from home is economical, convenient, low-power output, plug and play etc.In the family expenses base station system, base station from home is the wireless side network element.
Fig. 2 is the sketch map two of existing communication system architecture.As shown in Figure 2, base station from home can be linked into core network through this logical ne of home base-station gateway, also can be directly connected to core network (as shown in Figure 1); Wherein, The home base-station gateway major function is: the fail safe of checking base station from home, handle the registration of base station from home, and base station from home is carried out operation maintenance management; According to Carrier Requirements configuration and control base station from home, be responsible for the data of exchcange core net and base station from home.
Except the access of supporting mobile core network; GSM (comprising the base station from home system) also can be supported IP shunting function; Possess at the wireless side network element under the condition of IP shunting ability and the signatory IP of the permission shunting of user, can realize this locality access of terminal other IP devices of home network or internet.
Fig. 3 is the sketch map three of existing communication system architecture.Among Fig. 3, local gateway and home base-station gateway close to be established.The realization of IP shunting can provide providing powerful support for the IP dividing technology through setting up local gateway in Fig. 1, Fig. 2 and the system shown in Figure 3; Local gateway is linked into the gateway of external network (for example Intemet) as this locality; Address assignment, charging, packet package filtration, policy control, data distribution function, NAS/S1-AP/RANAP (Radios Access Network Application Part are provided; The wireless access network applying portion)/GTP (General Tunneling Protocol; General tunnel protocol)/PMIP (Proxy Mobile IP; Proxy mobile IP protocol)/function such as MIP (Mobile IP, mobile IP protocol) message parse, NAT (Network Address Translation, network address translation), IP distributing strategy route and execution.Local gateway can close with the wireless side network element and establish.
