摘要

A method in a multi-mode wireless communications device including initializing a counter (410), for example, upon changing location areas or attaching to a roaming network, scanning for service in all modes (440) of the multi-mode wireless communications device during at least one common search period, and after scanning for service in all modes of the multi-mode wireless communications device during the at least one common search period, scanning for service in each mode during subsequent search periods (450), wherein the multi-mode wireless communications device scans for service in not more than one mode during each of the subsequent search periods.
