Abstract: A method and apparatus for performing a handover of network connections upon a mobile terminal moving from a first access network to a second access network. The method includes obtaining IP connectivity and a first IP address for the mobile terminal through the first access network. In response to the mobile terminal moving from the first access network to the second access network, the method further includes sending a request for a new IP connectivity and a second IP address over the second access network, the request indicating a need to handover the network connections from the first access network to the second access network.

Abstract: Residential/Enterprise network connection management and handover scenarios. A method, system and device are provided for managing LIPA and/or SIPTO connection releases when UE moves out of residential/enterprise network coverage in case service continuity is not supported for the LIPA/SIPTO PDN connection(s). To address problems caused by not providing service continuity for LIPA/SIPTO PDN connections, the PDN connection/PDP context created in the HeNB/HNB by the MME/SGSN includes context information related to the UE indicating whether such connection is a LIPA PDN connection PDN connection or not. In particular, when the MME (1708) receives a handover request (17-1) from a source base station (1704), if it determines that the active PDN connections are LIPA PDN connections and that LIPA PDN continuity cannot be supported towards the target cell, the MME (1708) rejects the handover and sends (17-2) a Failure message to the source base station (1704).

Abstract: A method for saving power, at a mobile terminal, includes receiving a call, at a network entity, wherein the call contains information relating to transmission of the call from the network entity to the mobile terminal. The mobile terminal operates in first and second communications networks, which are different. The mobile terminal detects coverage of the first communications network and activates a first interface corresponding to the first communications network. The mobile terminal can also deactivate the first interface and activate a second interface corresponding to the second communications network while the mobile terminal is located in both the first and second communications networks. The mobile terminal can then enter a low power consumption mode supported by the second communications network.

Abstract: A mobile communication terminal includes a registration module that initiates a registration of the mobile communication terminal with Internet protocol (IP) multimedia subsystems (IMS) within a home network. The registration module initiates registration when the mobile communication terminal is roaming in a visited network. The mobile communication terminal also includes a session module that initiates a session set-up with the IMS to enable use of IMS resources. At least one of the registration module and the session module provide a first IP address to the IMS during at least one of the registration and the session set-up. The mobile communication terminal communicates with a first packet data network (PDN) that is local to the visited network using the first IP address in order to use at least one of the IMS resources.
