ABSTRACT:
A method for acquiring service from a more desirable wireless communication system while receiving service from a less desirable communication system is provided. The method may include acquiring service from a first communication system. The method may then involve waiting for a reattempt period that is related to a likelihood of acquiring service from a more desirable communication system. The method may then involve attempting to acquire service from a second communication system that is more desirable than the first communication system.
