Patent ID: 7398088

Claim:
A mobility manager for facilitating handover of ongoing communication of a first call between a wireless communication unit and a peer communication unit from a first communication network to a second communication network, the mobility manager comprising: a interface function to interface to the first communication network; and a controller coupled to and controlling the interface function to: obtain call information corresponding to the ongoing communication of the first call; ascertain a handover number for the wireless communication unit, the handover number terminating on the mobility manager associating with the first communication network, for use in facilitating the handover of the ongoing communication by initiating a handover call made by the wireless communication unit on the second communication network to the handover number while the first call is ongoing; receive the handover call from a network switching function for the first communication network, and facilitate connecting the peer communication unit to the handover call and sending a connect indication for the handover call to the wireless communication unit, and wherein the connecting the peer communication unit to the handover call further comprises one of a) transferring the ongoing communication of the peer communication unit to the handover call, b) conferencing the ongoing communication of the peer communication unit, the ongoing communication of the wireless communication unit, and the handover call together, and c) rerouting the ongoing communication with the peer communication unit to coincide with the routing of the handover call at the network switching function.
