  • Method and apparatus for remote unit passivation
    Patent number: 6553237
    Abstract: A method and an apparatus provide for controlling a remote unit's requests to access network resources in a wireless communication network. The method and apparatus scale back the frequency with which the remote unit attempts to establish a connection with a base unit, which connection would provide dial tone to a communication device associated with a remote unit. In accordance with the method, with each unsuccessful attempt to establish a connection with the base unit a retry timing interval is extended, thereby throttling back the number of establishment attempts by the remote unit.
