Abstract
A wireless communication device is disclosed that is capable of performing efficient handoffs in order to maximize connection time with either a serving or target base station. The wireless communication device performs measurements of only intra-frequency base stations to avoid retuning its radio module. Based on this information, as well as stored information relating to nearby base stations, the serving base station is able to estimate a position of the wireless communication device and compare the estimated position to positions of the known base stations in order to make a handoff decision. In addition, by storing information during measurement or handoff preparation, the device is capable of skipping handoff steps, immediately return to the serving base station after handoff failure, and/or perform streamlined PLMN searching.
