    • The invention relates to network devices and a method for supporting downlink paging for LIPA or SIPTO. According to an exemplary embodiment of the present invention there may be provided a method for supporting downlink paging for LIPA or SIPTO while a first UE using LIPA or SIPTO service has been moved to an idle mode. The method may comprise monitoring UE traffic while the first UE 10 is in the active state and storing a UE IP address for a default EPS bearer of the first UE 10 in a node and in a gateway for LIPA or SIPTO service. Moreover, the method may comprise sending a downlink datagram for paging activation towards the first UE 10 over an existing tunnel 80, wherein the tunnel was established for a second UE 11 being in an active state, wherein the tunnel 80 may be established for the second UE 11 or any other UE served by the same node and the same gateway, and activating a paging procedure by receiving the downlink datagram via the tunnel in a gateway, which gateway is serving the first UE 10 for the default EPS bearer service of the first UE 10.
    • 本发明涉及网络设备和支持LIPA或SIPTO的下行寻呼的方法。 根据本发明的示例性实施例,可以提供一种用于支持LIPA或SIPTO的下行链路寻呼的方法,同时使用LIPA或SIPTO服务的第一UE已经移动到空闲模式。 该方法可以包括在第一UE 10处于活动状态时监视UE业务,并且在节点和用于LIPA或SIPTO服务的网关中存储用于第一UE 10的默认EPS承载的UE IP地址。 此外,该方法可以包括通过现有隧道80向第一UE 10发送用于寻呼激活的下行链路数据报,其中为第二UE 11处于活动状态建立了隧道,其中隧道80可以被建立用于第二 UE 11或由相同节点和相同网关服务的任何其他UE,并且通过经由网关中的隧道接收下行链路数据报来激活寻呼过程,哪个网关为第一UE 10服务于第一UE的默认EPS承载服务 UE 10。
