Abstract: A wireless communications device obtains a configuration identifier and selects a wireless communications configuration from among a plurality of wireless communications configurations stored in a non-volatile memory of the wireless communications device based on the configuration identifier. The wireless communications device applies the selected wireless communications configuration to configure the device for use with a network. Respective ones of the plurality of wireless communications configurations may correspond to respective networks; and the configuration identifier may include a network identifier obtained, for example, from a subscriber identity module (SIM) engaged with the wireless communications device.

Abstract: In a radiocommunication system including at least one base station and a mobile station connected across a first radio channel to the base station, the signal strengths of the first radio channel and neighboring radio channels are measured in the mobile station to determine whether reselection to a neighboring radio channel is necessary. Each radio channel is measured at various points in a frame period or in different frame periods, the measurements occurring in different time slots. The points at which the signal strength measurements of each radio channel are made may be rotated among the different frame periods, the measurements may be made at random points in the different frame periods, or the starting times of the measurements may be rotated among or occur randomly in the different frame periods. Alternately, the signal strengths of each radio channel may be measured at different points in a single frame period.
