[57] ABSTRACT
A mobility processor (34) provides location update parameters to a subscriber unit (SU1-4). The location update parameters indicate conditions upon which the subscriber unit is to provide its location information to the mobility processor. From the location information, the mobility processor determines whether the subscriber unit has provided the location information in a manner that is consistent with the location update parameters. If the mobility processor determines that the subscriber unit did not provide the location information in a manner that is consistent with the location update parameters, the mobility processor generates a new set of location update parameters which are provided to the subscriber unit.
