Abstract

A wireless communication unit (101, 200), network switch (112, 300) and corresponding methods facilitate routing and handover or handin of calls from a second network (105) to a first network (103) when the unit has been operating in second network and is being handed in to the first network. The communication unit comprises a transceiver (203) and a controller (209) arranged to operate with the transceiver to determine (503) that the wireless communication unit is within a coverage area of the first network; to exchange messages (505, 507) corresponding to call appearance information with the switch in the first network; to decide whether a call within the second network can be handed in to the first network based on the exchange of the messages (507); and to initiate (519, 619) a handin of the call to the first network only when the decision is affirmative.
