Method and system for accessing local network by mobile terminal via home base station system

摘要

A method and system for accessing a local network by a mobile terminal via a home base station system are provided. The method comprises: a home base station subsystem, in which the mobile terminal is located, sending an ID of a local gateway module in the home base station subsystem to a core network management network element, and the core network management network element determining that the mobile terminal needs to access the local network, and setting up a GPRS tunneling control bearer with the home base station subsystem according to the ID, so that the mobile terminal can access the local network via the home base station subsystem. The method and the system makes the core network acquire the address of the local GGSN/PDN-GW corresponding to the home base station without manual configuration, thus reducing the complexity of the network configuration.

1. A method for accessing a local network by a mobile terminal via a home base station system, comprising:
a home base station subsystem, in which the mobile terminal performing a local Internet Protocol (IP) access is located, sending an identification of a local gateway module in the home base station subsystem to a core network management network element; and the core network management network element determining that the mobile terminal needs to access the local network, and then setting up a general packet radio service, GPRS, tunneling control bearer with said home base station subsystem according to the identification, so that the mobile terminal is able to access the local network via the home base station subsystem; wherein, after said home base station subsystem sends the identification of the local gateway module to the core network management network element, said method further comprises: said mobile terminal initiating a packet data protocol context request message to the core network management network element, and carrying an access point representing a local access in the message; the step of said core network management network element determining that the mobile terminal needs to access the local network comprises: said core network management network element determining that the mobile terminal needs to access the local network according to said access point.
