    • The technology described herein relates to a method in a gateway device and a gateway device for handling a context of a UE moving from a source HeNB (220) to a target HeNB. The gateway device is configured to receive a path switch request message from the source HeNB including a first pair of IDs and the gateway device is configured to transmit a second path switch request message to an MME including a second pair of IDs associated to the first pair of IDs. When the gateway device receives a UE context release request message from the source HeNB, the gateway device determines whether IDs in this message are associated to the same second pair of IDs. If this is the case, the gateway device maintains the UE context otherwise the gateway device releases or de-allocates the UE context.
    • 本文描述的技术涉及网关设备和网关设备中的方法,用于处理从源HeNB(220)移动到目标HeNB的UE的上下文。 网关设备被配置为从源HeNB接收包括第一对ID的路由交换机请求消息,并且网关设备被配置为向MME发送包括与第一对相关联的第二对ID的第二路径切换请求消息 的ID。 当网关设备从源HeNB接收到UE上下文释放请求消息时,网关设备确定该消息中的ID是否与相同的第二对ID对相关联。 如果是这种情况,则网关设备维护UE上下文,否则网关设备释放或解除分配UE上下文。
