Abstract

A management unit allocates network resources to a plurality of multiservice communication devices capable of communicating via a plurality of networks. The management unit includes a communication device interface for facilitating a bidirectional data communication with the plurality of multiservice communication devices via a wireless control channel, the bidirectional data communication including outbound control data sent to at least one of the plurality of multiservice communication devices and inbound control data received from at least one of the plurality of multiservice communication devices, wherein the wireless control channel is separate from the communication between the plurality of multiservice communication devices and the plurality of networks. A network interface receives network resource data from the plurality of networks. A management processing unit generates the outbound control data in response thereto, wherein the management processing unit facilities the handoff of a real-time service accessed by the at least one of the plurality of multiservice communication devices via a first network of the plurality of networks to a second network of the plurality of n…
