Method and system for controlling establishment of local IP access

摘要

The present invention discloses a method for controlling establishment of a local IP connection, and the method includes: when an access gateway determines that data or application of a terminal needs to be offloaded, informing the terminal that a local IP connection needs to be established via a mobility management entity and a radio side network element by a bearer modification, or informing a radio side network element or a local gateway of a routing policy via a mobility management entity. The present invention also discloses a system for controlling establishment of a local IP connection. The present invention enables the terminal to instantly acquire whether a local IP connection needs to be re-established, can realize dynamic adjustment of local IP data; meanwhile, the present invention can realize dynamic adjustment of local IP data and dynamic establishment of the local IP connection in the case of the local IP connection.

1. A method for controlling establishment of a local IP access, comprising:
when an access gateway determines a type of data or an application of a terminal needs to be offloaded, informing the terminal that a local IP connection needs to be established via a mobility management entity and a radio side network element by a bearer modification, or informing a radio side network element or a local gateway of a routing policy via a mobility management entity; wherein, the radio side network element is a base station, a Home (e)NodeB, a radio network controller (RNC), a Home (e)NodeB gateway, or a traffic offload function entity; the mobility management entity is a mobility management element (MME), a mobile switching center (MSC), or a Serving General Packet Radio Service (GPRS) support node (SGSN); the access gateway is a packet data network gateway (PGW) or a gateway GPSR support node (GGSN); the local gateway is a local serving gateway (L-SGW) and a local packet data network gateway (L-PGW); or a separate L-PGW; or a local gateway GPRS support node (L-GGSN) and a Local Serving GPRS Support Node (L-SGSN); or a separate L-GGSN; or a traffic offload function entity.
