Problems solved by technology

Such a full scan already takes a considerable amount of time in dense or complex wireless environments such as today, and this situation will be exacerbated when additional frequency bands are introduced and more access technologies are integrated
[0004] In addition, it should be noted that in most cases, full bandwidth scanning will reduce the utilization efficiency of wireless resources
Related to this, the time to perform a full scan can be very long, so that the wireless environment has changed greatly from the start of the scan until the UE device decides to select a new PLMN

Abstract

A system and method for accelerating network selection by a wireless user equipment (UE) device (102) without having to perform a full band scan (FBS). In one exemplary embodiment, the wireless UE device (102) is operable to determine its location using a satellite-based positioning system such as GPS. Based on determining (1004) that the wireless UE device is in a particular area defined by a set of corners, a subset of appropriate frequency data is determined for selective scanning (1006) by the wireless UE device (102). Using the subset of appropriate frequency data, a selective scanning (1006) is performed for locating a network by the wireless UE device (102).
