A wireless communication unit (101, 200, 401), network switch (112, 300,
407) and corresponding methods facilitate retrieval, routing, and
management of on-hold calls (FIG. 4-FIG. 7) 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
support a handout to and while the unit is operating in the second
network. A user interface (211) and in band signaling over the call leg
facilitates management, connecting, disconnecting, etc., of the on-hold
calls by the communication unit.
