一种LIPA/SIPTO连接的建立方法和装置
摘要：
本发明公开了一种LIPA/SIPTO连接的建立方法和装置。其中，该方法包括：MME接收基站发送的LIPA/SIPTO标识信息，并在根据该LIPA/SIPTO标识信息确定该基站支持该LIPA/SIPTO功能时，获取该基站对应终端的公用数据网PDN连接；获取该PDN连接所对应终端的签约信息，在根据该签约信息确定该终端支持该LIPA/SIPTO功能时，释放该终端对应的PDN连接，并在释放该PDN连接后，若终端重新发起PDN连接请求，与本地网关LGW建立LIPA/SIPTO连接。本发明解决了无法实时将普通PDN连接更新为LIPA/SIPTO连接的技术问题。
摘要（英）：

Disclosed are an LIPA/SIPTO connection establishment method and device. The method comprises: an MME receives LIPA/SIPTO identification information sent by a base station; acquire a public data network (PDN) connection of a terminal corresponding to the base station when it is determined, according to the LIPA/SIPTO identification information, that the base station supports an LIPA/SIPTO function; acquire subscription information of the terminal corresponding to the PDN connection; release the PDN connection corresponding to the terminal when it is determined, according to the subscription information, that the terminal supports the LIPA/SIPTO function; and after the PDN connection is released, establish an LIPA/SIPTO connection with a local gateway (LGW) if the terminal again initiates a PDN connection request. The present invention solves the technical problem that a common PDN connection cannot be updated to an LIPA/SIPTO connection in real time.
