Abstract
A cellular network mobile station (MS) is configured for roaming operation. A prioritization of one or more Public Land Mobile Network (PLMN) configurations is stored at the MS. When the MS is attached or registered for access to a PLMN that is not a Home PLMN or PLMN configuration that is not a highest priority PLMN configuration, it performs an idle mode search for a higher priority PLMN configuration at intervals of time. A duration of the intervals is determined according to a primary search period parameter stored at the MS. The MS is configured with a secondary search period parameter, which indicates one or more factors to be applied to the primary search period parameter when determining the duration of the intervals, such that each of the factors is applied according to a respective associated condition indicative of a number of PLMN configurations available for the MS to access.
