Embodiment Construction

[0042] The inventive idea of ​​the present invention is: when the mobility management unit knows that there is downlink data coming, it judges the source of the downlink data, and when the downlink data is local access data, it performs paging in the local access area.

[0043] The local access area refers to the area covered by the base station under the local access gateway, or referred to as an area supporting local access.

[0044] Specifically, the mobility management unit may determine the source of the downlink data according to the information of the gateway to which the downlink data arrives or the PDN connection information, and if the gateway is judged to be a local gateway according to the gateway information, then the downlink data is considered as local access data , performing paging in the local access area; if judging that the downlink data is local access data according to the PDN connection information, performing paging in the local access area. The gateway...

Abstract

The invention discloses a paging optimization method and device for local access. By adopting the method and the device, the paging range can be determined more accurately and paging is only carried out in the regions supporting local access. The method comprises the following step that: when learning that downlink data come, a mobility management unit judges the origins of the downlink data and carries out paging in the local access region when the downlink data are local access data.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a paging optimization method and device under the use of local access functions (including local IP access and selective IP transmission distribution). 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 reduce the operating costs of operators, 3GPP (3rd Generation Partnership Project , Third Generation Partnership Project) standard working group is working on the research of Evolved Packet System (EPS for short). figure 1 A schematic diagram showing the structure of an 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 a Home Subsc...
