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

Embodiment Construction
[0068] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail by citing the following embodiments and referring to the accompanying drawings.
[0069] The present invention provides a system for realizing local access, such as Figure 4 shown. compared to existing technology figure 2For a system that implements local access, a local access control server is added. The local access control server is used to save the mapping relationship between the macro base station system and its corresponding local gateway and / or the mapping relationship between the home base station system and its corresponding local gateway. The mapping relationship refers to the mapping relationship established between the macro station system cell identifier, or routing identifier, or tracking identifier, or the identity identifier of the macro station system, or the location identifier information of t...

A system and method for implementing a local access are disclosed to solve the gateway selection problem in a local access visit. With the present invention, a mapping relation between a Macro NodeB system / Home NodeB system and its corresponding local gateway is saved in a newly-added local access control server, and is updated via an A2 interface or an A3 interface. When establishing a local access connection, a user equipment acquires an address of the local gateway from the local access control server, and establishes the corresponding local access connection. The application of the present invention enables a centralized management for the mapping relation between a Macro NodeB system / Home NodeB system and its corresponding local gateway, and establishes a corresponding update mechanism, which ensures that a correct gateway is selected when a local connection is established, and thereby the gateway selection problem in a local access visit 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...
