Description
Technical field
The present invention relates to the mobile communication technology field, roaming user data route optimizing system of selection in particularly a kind of 3GPP network.
Background technology
3GPP is as digital communication technology of future generation innovation development trend and target, beyond doubt one of focus of attracting most attention of the world today.The network configuration of 3GPP is made up of circuit domain and packet domain two parts basically, and Fig. 1 is existing 3GPP communication system network structural representation.As shown in Figure 1, this network configuration has adopted and the similar structure of second generation mobile communication system, comprises universal mobile telecommunications system land radio access web (UTRAN), GSM EDGE Radio Access Network (GERAN), core net (CN) and user terminal (UE).Wherein, GERAN/UTRAN is used to realize all and wireless function associated, and all voice calls are connected with data in CN processing GPRS/UMTS (GPRS/universal mobile telecommunications service) system, and are used to realize and the exchange of external network and the function of route.CN from be divided in logic circuit commutative field (Circuit Switched Domain, CS) and packet-switched domain (PacketSwitched Domain PS), supports speech and data service respectively.The CS territory comprises Mobile Switching Center Server (MSC-Server), media gateway (MGW) and Gateway Mobile Switching Center server nodes such as (GMSC-Server).Wherein, MSC-Server is used to transmit the chain of command data in CS territory, realize mobile management, call out functions such as control and authentication ciphering, GMSC-Server is used to realize the calling control of GMSC and the chain of command function that mobility is controlled, and MGW is used to realize the transmission of user face data; The PS territory comprises service universal grouping wireless business supporting node (SGSN) and ggsn nodes such as (GGSN).Wherein, GGSN mainly is responsible for and external network carries out interface, and simultaneously, GGSN also is responsible for realizing the transmission of user face data.Position and the MSC Server in CS territory of SGSN in the PS territory is similar, and its Core Feature is to realize functions such as routing forwarding, mobile management, session management and user profile storage.(Home Location Register HLR) is used for storing user subscription information to attaching position register, and this equipment is all used in CS and PS territory.
3GPP is studying a kind of brand-new evolution network framework in order to strengthen the competitiveness of future network, comprises the Long Term Evolution (LTE) of System Architecture Evolution (SAE) and Access Network, and the Access Network of evolution is called E-UTRAN.The packet core network structure of 3GPP system evolved as shown in Figure 2, comprise Mobility Management Entity (Mobility Management Entity, MME), user entity (User Plane Entity, UPE) and three logical functional entities of the user's face anchor point between the different access systems (Inter Access System Anchor, InterAS Anchor).Wherein, MME is responsible for the mobile management of chain of command, comprises the management of user's context and mobile status, and distributing user temporary identity sign etc. are corresponding to the control plane part of current GPRS/UMTS internal system SGSN; UPE is responsible for initiating paging for downlink data under the idle condition, and IP bearing parameter and the interior routing iinformation of network etc. are preserved in management, corresponding to the datum plane part of current GPRS/UMTS internal system SGSN and GGSN; Inter AS Anchor then serves as the user's face anchor point between different access systems.(Policy andCharging Rule Function PCRF) is used for policy control decision and flow based charging controlled function to the "Policy and Charging Rules Function entity.(Home Subscriber Server HSS) is used for storing user subscription information to home subscriber server.
In the evolvement network in future, all business of mobile subscriber comprise that grouping, voice and multimedia etc. all carry by IP, therefore the routing optimality above has very strong current demand, for example the conversation between roamer other mobile subscribers in roaming place and roaming place will be roamer's a main business, if be not optimized, business datum also needs by the home network routing forwarding, not only waste Internet resources, and reduce user's quality of service, so the routing optimality of roaming user data is necessary.Just having described the function of routing optimality in present 23.882 agreements can determine by consulting between the operator of the operator of home network and visited network, but which service needed is used the routing optimality function, which business can not be used the function of routing optimality, and hold consultation according to what principle and parameter, do not describe in the agreement.

2), the PCRF of visited network carries out the strategy decision;
3), information such as the PCRF of the visited network strategy that will determine and business sends to the PCRF of home network;
4) if, the PCRF of home network do not have user's tactful subscription data, then sends a request message request user's tactful subscription data to SPR;
5), SPR echoes and answers message to give the PCRF of home network, and user's tactful subscription data is carried PCRF to home network;
6), the PCRF of home network is according to relevant information, carries out the strategy decision;
7), the PCRF of home network sends the PCRF of policy response message to visited network, and the policy information of decision is carried PCRF to visited network;
8), the PCRF of visited network offers policy information the PCEF entity of gateway.Above-mentioned flow process only comprises flow process related to the present invention, is not whole flow processs, actual flow process may with this flow process difference to some extent.
Figure 11 is the application network structural representation of fourth embodiment of the invention.As shown in figure 11, in the application network structure of fourth embodiment of the invention, do not adopt PCRF to carry out the routing optimality policy control, the routing optimality policy configurations is at gateway device, for example in the service universal grouping wireless business supporting node (SGSN) and ggsn (GGSN) of Inter AS Anchor (the user's face anchor point between the different access systems), UPE (user entity), 2G, 3G system.Judge whether this business needs to use PCC (strategy and the control of chargeing) to handle receive roamer's service request when the gateway device of visited network after, if unwanted words, then inquire about the configuration (this configuration is the Local Breakout routing optimality strategy of the operator of home network and visited network to the roamer) in the gateway, the business of using according to the result who checks out and roamer judge this business whether needs use the function of LocalBreakout routing optimality.
Figure 12 is the application network structural representation of fifth embodiment of the invention.As shown in figure 12, in the application network structure of fifth embodiment of the invention, do not adopt PCRF to carry out the routing optimality policy control, the routing optimality policy configurations is in HSS.When the roamer obtains the routing optimality policy information of contracting in HSS when visited network is registered, and be saved in its context; The gateway device of visited network judges whether this business needs to use PCC (strategy and the control of chargeing) to handle after receiving roamer's service request, if unwanted words, then inquire about the routing optimality policy information (this information is the Local Breakout routing optimality strategy of the operator of home network and visited network to the roamer) in the context, the business of using according to the result who checks out and roamer judge this business whether needs use the function of Local Breakout routing optimality.
Though described the present invention by execution mode, those of ordinary skills know, the present invention has many distortion and variation and do not break away from spirit of the present invention, and all drops in the protection range of claims of the present invention.
