System and method for realizing local access

Abstract

The invention discloses a system and method for realizing local access, which are used for solving the problem of gateway selection in the local access. The method comprises the following steps of: storing a mapping relation between a macro station system / a family base station system and a locate gateway corresponding to the macro station system / the family base station system into an added local access control server; updating the mapping relation through an A2 interface or an A3 interface; and obtaining an address of the local gateway from the local access control server and establishing the corresponding local access connection when user equipment establishes local access connection. In the invention, because the centralized management of the mapping relation between the macro station system / the family base station system and the corresponding locate gateway corresponding to the macro station system / the family base station system is realized, a corresponding updating mechanism is established and the correct gateway selection is facilitated when the local connection is established, the gateway selection problem in the local access is solved.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a system and method for realizing local access. 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 It is a schematic diagram of the structure of the existing packet domain (PS) and evolved packet domain (EPS) systems and a schematic diagram of the corresponding home network, such as figure 1 As shown, the whole system is divided into two parts, the wireless access network and the core network. In the wireless access system, the PS system inc...

Problems solved by technology

When the macro base station system / femtocell system is connected to multiple local gateways and core network gateways, the existing gateway selection mechanism cannot select the correct local gateway for local access

At the same time, because the local access function can provide services for home users or enterprise users, the corresponding local gateway is relatively small compared with the core network gateway, and may also be located in the homes of home users or enterprises, which makes it inconvenient for operators to monitor their status. manage
