摘要:
A mobile communication device (102) includes a wide area network (WAN) modem (122) for communicating over a wireless WAN. During a voice call, the WAN modem operates in a power save mode (206) but must occasionally scan for handover candidate base stations (208). The modem goes directly from the power save mode to a scan mode at an agreed upon time, first selected by the mobile communication device, but which may be modified by the base station.
