System and method for network discovery

Abstract

A method for establishing a network connection includes determining a list of access networks detectable by a user equipment, and reducing the list of access networks to a list of preferred networks in accordance with supplemental information associated with the user equipment. The method also includes selecting a first candidate network from the list of preferred networks, and attempting to connect to the first candidate network.

Description

technical field [0001] The present invention relates generally to digital communications, and more particularly to a system and method for network discovery. Background technique [0002] Network standards bodies such as the WiMAX Forum and 3GPP study single-radio handover from / to their networks. The IEEE802.21c task group is also working on a single radio handover standard. In general, the advantage of single-radio switching is that the peak transmit power requirements from the target / source transmit radio to the source / target receiver radio are reduced and signal filtering becomes less complex, resulting in lower cost for multi-radio devices. [0003] In single-radio handover, since a device (also commonly referred to as user equipment, mobile station, mobile node, subscriber, user, terminal, etc.) uses a radio, the device cannot freely use the radio tuned to the target wireless network while the radio tunes to the source wireless network. network radio. Therefore, the ...
