    • PROBLEM TO BE SOLVED: To provide a method for transmitting/receiving a control message among a serving gateway and a PDN(Packet Data Network) gateway and an MME(Mobility Management Entity) existing on an extended femto base station.SOLUTION: A local IP access support method comprises: a step that when a service request is received from a terminal, an initial terminal message including the information of a local gateway is generated and transferred to a mobility management entity; a step that an initial context setting request message including information necessary for radio bearer formation to be transferred from the mobility management entity is received and stored; a step that a PDN connection request for local IP access is received from the terminal, and transferred to the mobility management entity; a step that when the mobility management entity transfers the bearer generation request to the local gateway, the local gateway forms the radio bearer. The local gateway is positioned on the femto cell.
    • 要解决的问题:提供一种在扩展毫微微基站上存在的服务网关和PDN(分组数据网络)网关和MME(移动性管理实体)之间发送/接收控制消息的方法。解决方案:本地IP 访问支持方法包括:当从终端接收到服务请求时,生成包括本地网关的信息的初始终端消息并将其传送到移动性管理实体; 接收并存储包括从移动性管理实体传送的无线电承载形成所需的信息的初始上​​下文设置请求消息的步骤; 从终端接收到本地IP接入的PDN连接请求并传送到移动性管理实体的步骤; 当移动性管理实体将承载生成请求传送到本地网关时,本地网关形成无线承载。 本地网关位于毫微微小区上。
