Abstract
A method for selecting an alternate wireless communication system for a wireless communication device is disclosed. The method comprises using a first radio access technology (RAT) by a wireless communication device when scanning (202) for an initial wireless communication network (201). The wireless communication device further registers (215) to the initial wireless communication network (201). Then, the initial wireless communication network (201) determines (206) alternate RAT wireless communication network information for the wireless communication device and sends (235) the alternate RAT wireless communication network information to the wireless communication device. The wireless communication device receives the alternate RAT wireless communication network information and selects (240) a first alternate wireless communication network from within the alternate RAT wireless communication network information, scans for the first alternate wireless communication network using an alternate RAT and registers with the first alternate wireless communication network using the alternate RAT.
