Problems solved by technology

From the perspective of routing relationship, for service server 2, the best service anchor point is P-GW2; for service server 3, the best service anchor point is P-GW3, but the current selection mechanism can only select P-GW1, but using P-GW1 to access service server 2 and service server 3, because the route is not the best route, the service delay is increased, and the load of the transmission network is also increased

Embodiment Construction

[0074] In order to make the object, technical solution and beneficial effects of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0075] figure 2 An example shows a method for configuring service data routing provided by an embodiment of the present invention, as shown in figure 2 As shown, the method may include:

[0076] S201. The MME allocates multiple service anchor points to the terminal during the terminal attachment process; the terminal has the same address information in the multiple service anchor points.

[0077] Specifically, the address of the terminal may be pre-configured in the HSS, so that the terminal has the same address information in the multiple service anchor points. The MME may also not...

Abstract

The embodiment of the invention relates to the technical field of communication, in particular to a service data routing method, a service gateway and a mobile management entity (MME), which comprisesthe following steps that: the service gateway receives a session creation request message sent by the MME; The service gateway establishes a tunnel with each service anchor point in each service anchor point; The service gateway receives the service data sent by the terminal; The service gateway determines a service anchor point of the service data from a plurality of service anchor points corresponding to the terminal according to the attribute information of the service data; And finally, the service gateway routes the service data to the corresponding packet data network through the service anchor point. It can be seen that in one APN, the service gateway can determine the service anchor point of the service data from a plurality of service anchor points corresponding to the terminal according to the service data flow, so that an optimal route can be selected for the terminal, the service delay can be reduced, the problem of roundabout routing can be relieved, and the load of a transmission network can be reduced.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular to a service data routing method, a service gateway and a mobility management entity. Background technique [0002] At present, the 4G (the 4 Generation mobile communication technology, fourth-generation mobile communication technology) mobile communication core network is called the evolved packet core network, which mainly includes MME (Mobility Management Entity, mobile management entity), S-GW (Serving Gate Way, serving Gateway) and service anchor P-GW (PDNGateWay) network element, MME completes terminal access, authentication, mobility management, connection management and other functions; B) The anchor point and service forwarding node are responsible for handling the mobility of terminals between eNodeBs; the service anchor point P-GW is the PDN gateway, which is the gateway node connecting the mobile core network to the external PDN, responsible for te...
