1. A method for detecting availability of an alternate wireless communication system, the method comprising:
- registering with a first wireless communication system having a first communication protocol from a wireless terminal;
determining if the wireless terminal has moved out of a selected geographic region; and
scanning for the alternate wireless communication system responsive to determining that the wireless terminal has moved out of the selected geographic region, the alternate wireless communication system having a second communication protocol that is different from the first communication protocol.

Abstract
A method for detecting the availability of an alternate wireless communication system. A wireless terminal registers with a first wireless communication system. A determination is made as to whether the wireless terminal has moved out of a selected geographic region. An alternate wireless communication system is scanned for responsive to determining that the wireless terminal has moved out of the selected geographic region. The alternate wireless communication system has a communication protocol that is different from a communication protocol of the first wireless communication system.
