摘要： A technique is provided for synchronizing a first call state of a network component and a second call state of a mobile device. The mobile device is connectable to a network via a first Radio Access Technology (RAT) and a second RAT. The network forwards towards a callee an invitation for a call originating via the first RAT from the mobile device. The network sends a first message corresponding to a callee response towards the mobile device. The network component triggers a transfer of the call session of the mobile device from the first RAT to the second RAT. The first call state is set by the response of the callee. Information indicative of the second call state is received from the mobile device, and a second message for changing the second call state by the response is provided to the mobile device when inconsistent first and second call states.

摘要： A technique for triggering a change of a call state of a mobile device is presented. A network forwards towards a callee an invitation for a call originating via a first Radio Access Technology (RAT) from the mobile device, and forwards a response of the callee via the first RAT towards the mobile device. The response indicates a change of the call state from a first state to a second state. A first network component changes via a second RAT the call state of the mobile device when receiving information indicative of the first state followed by receiving a message indicative of the second state. A second network component receives from the first network component an invitation for a transfer of the call of mobile device from the first RAT to the second RAT.

摘要： In one aspect, a method for a packet gateway node (PGW) is disclosed. The PGW being adapted for (a) communicating with at least a serving gateway node, SOW, (b) receiving and forwarding downlink data packets to a user entity, UE, and (c) communicating with a mobility management entity, MME. In one embodiment, the method comprises: the PGW, when receiving a downlink user plane data packet destined for the UE on a Packet Data Network, PDN, connection associated with a restarted SGW, determining if the PDN connection has not yet been relocated to a new SGW, and, if so, selecting at least one SGW from a set of SGWs including the restarted SGW or another SGW and transmitting a control plane signal to at least one of the selected SGWs, the control plane signal identifying at least the UE.
