Abstract:
1. A method for handover of a communication of a mobile communication device between a first radio access network and a second radio access network, the method comprising: storing, by at least one of the communication device and an element of the first radio access network, a context of the communication device in the first radio access network, the context being useable to transfer the communication back to the first radio access network after a transferring to the second radio access network; transferring the communication to the second radio access network; before the transferring, signaling, by the first radio access network, an activity cycle to the communication device, the activity cycle defining times when the communication device can send uplink signals; after the transferring, periodically sending, by the communication device, an uplink signal to the first radio access network, the uplink signal indicating a status of the communication in the second radio access network; and after the transferring, switching a radio resource control state of the communication device in the first radio access network from an active state to an idle state, the communication device being pageable while in the idle state by the first radio access network.
