On hold call retrieval and routing
First Claim
1. A wireless communication unit arranged and constructed for operation within a loosely coupled communication network comprising a first communication network and a second communication network, the wireless communication unit comprising:
- a transceiver configured to support an air interface with the first communication network and with the second communication network; and
a controller arranged to control and cooperatively operate with the transceiver to manage and retrieve an on-hold call on the first communication network after a handout of the wireless communication unit from the first communication network to the second communication network via a call leg established to support the on-hold call while the wireless communication unit is operating in the second communication network, wherein the on-hold call is a call placed on-hold when the wireless communication unit is in the first communication network.

Abstract
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.

3. A communication network switch operable to route calls for a first communication network, the communication network switch comprising:
-
a switching function operable to couple the first communication network to a second communication network, where the first communication network and the second communication network comprise a loosely coupled communication network; and a controller arranged to control and cooperatively operate with the switching function to manage and retrieve an on-hold call on the first communication network after a wireless communication unit is handed out from the first communication network to the second communication network via a call leg established to support the on-hold call while the wireless communication unit is operating in the second communication network, wherein the on-hold call is a call placed on-hold when the wireless communication unit is in the first communication network. - View Dependent Claims (4)
