Abstract
The possibility of incompatibility between wireless communication system stations having the most recent protocol revisions is addressed by transmitting from the base station to a mobile station characteristics that identify a mobile station group that is restricted to using less than the most recent protocol revision. Using less than the most recent protocol revision may involve using an earlier revision or a subset of the most current protocol revision. This permits a base station to direct mobiles to avoid using protocol revisions or features of protocol revisions that have been insufficiently tested or that have a history of problems for a particular base station/mobile station combination. Additionally, when a mobile station receives a message from a base station identifying which mobile stations are subject to what set of restrictions, the mobile station then sends a message to the base station requesting service that matches the restrictions that were identified associated with the group to which the mobile station belongs.
