ABSTRACT:
A wireless communication unit (101, 200), network switch (112, 300) and corresponding methods facilitate retrieval, routing, and management of on-hold calls (FIG. 5) within a first communication network (103) when the unit is operating in a second communication network (105) that is loosely coupled to the first. The communication unit comprises a transceiver (203) configured to support an air interface with the first and the second communication network; and a controller (209) arranged to cooperatively operate with the transceiver to retrieve an on-hold call from the first network via a call leg established to handout on-hold calls to and while the unit is operating in the second network. A user interface (211) facilitates management, connecting, disconnecting, etc., of the on-hold calls by the communication unit.
