Abstract
A network search method of a user equipment (UE) for a wireless communication system that improves network search speed for acquiring Public Land Mobile Network (PLMN) available list available where the user equipment is located. A network search method measures powers of all the frequency bands supported by a UE in response to a network search request, generates a scan list as a result of measurement of the powers, searches networks listed in the scan list for available channels; acquires neighbor cell information from a system information message of one of the available channels. In addition, the method skips the networks indicated by the neighbor cell information in search of networks by removing the networks from the scan list.
