Abstract

Systems and methodologies are described that facilitate improved multi-mode system selection in a wireless communication system. As described herein, various techniques can be utilized to synthesize system databases corresponding to disparate groups of radio access technologies (RATs), such as a Public Land Mobile Network (PLMN) list and / or a Preferred Roaming List (PRL), with one or more overlay databases and associated location information to generate a multi-mode list of preferred systems. As described herein, a preferred system listing can be constructed to leverage fine granularity of information in one or more databases while still supporting databases with coarser information. Techniques are additionally described herein for augmenting and / or grouping one or more overlay databases to facilitate a higher available granularity of information for various RATs than that provided in system databases corresponding to the RATs. Techniques are additionally provided for automated generation of preferred system listing based on changes to observed location.

Description

[0001] cross reference [0002] This application claims priority to U.S. Provisional Application No. 61 / 082,100, filed July 18, 2008, entitled "PREFERRED SYSTEMSELECTION ENHANCEMENTS FOR MULTI-MODE WIRELESS SYSTEMS," which is assigned to the assignee of this application , which is hereby expressly incorporated herein by reference. technical field [0003] Generally speaking, the present invention relates to wireless communication, and specifically, the present invention relates to the technology of system selection in the wireless communication environment. Background technique [0004] Wireless communication systems are widely deployed to provide various communication services, for example, voice, video, packet data, broadcast and messaging services can be provided through such wireless communication systems. These systems may be multiple-access systems that support communication for multiple terminals by sharing available system resources. Examples of such multiple-acces...
