Embodiment Construction

[0100] The basic idea of ​​the present invention is: the service gateway executes the routing optimization judgment according to the obtained routing optimization judgment information, and executes the establishment of the routing optimization channel when it is judged that the routing optimization can be performed.

[0101] The routing optimization method of the present invention is applicable to two users communicating with each other under the same service gateway, and the two users may use the same / different anchor gateways, and the present invention is not limited to core network elements.

[0102] Figure 3(a), (b) is a schematic diagram of the route optimization channel of the present invention, as shown in Figure 3(a), 3(b), the applicable scenarios of the route optimization method of the present invention include the same service gateway and the same anchor gateway situation (Figure 3(a)), and the situation of the same serving gateway but different anchor gateways (Figu...

Abstract

The invention discloses a routing optimization method. The method comprises: a service gateway executes routing optimization determination according to obtained routing optimization determination information; and when the service gateway determines that routing optimization can be carried out, routing optimization channel establishment is executed. In addition, the invention also discloses the service gateway and a routing optimization system. According to the technical scheme, time delay of data transmission can be reduced and a network load of a core network is also reduced.

Description

technical field [0001] The invention relates to route optimization technology, in particular to a route optimization method and system, and a service gateway. Background technique [0002] In order to maintain the competitiveness of the third-generation mobile communication system in the communication field, provide users with faster rate, lower delay, and more personalized mobile communication services, and at the same time, in order to reduce the operating costs of operators, the third-generation cooperation The standard working group of the Partnership Project (3GPP, 3rd Generation Partnership Project) is working on the research of the Evolved Packet System (EPS, Evolved Packet System). figure 1 It is a schematic diagram of the structure of the evolved packet domain system, such as figure 1 As shown, the entire EPS system is divided into two parts, the wireless access network and the core network. The core network includes Home Subscriber Server (HSS, HomeSubscriber Ser...
