A wireless communication unit (CU) (fig. 4), corresponding network controller (fig. 5), and methods (fig. 8, etc.) operate to route calls and facilitate a call handover from one wireless network to another. The CU comprises a transceiver (403) suitable to support an air interface with a first and second wireless communication network (304, 305); a memory (415) operable to store information (431) suitable for identifying an enterprise controller; and a controller (405) configured to facilitate setting up a call. The controller thereafter if the call needs to be handed over from one to another of the first and second communication network, uses the information to facilitate identification of a unique one of a plurality of enterprise controllers for effecting a hand over of the call. |
