ABSTRACT:
Apparatus, and an associated method, performing synchronization messages to be used to synchronize operation of a mobile station with that of a base transceiver station in a cellular, or other radio communication system. The formatter of a message generator formats two or more different sync channel messages, a first of which is used by a mobile station constructed according to a pre-IS-2000 cellular communication standard, and a second of which is utilized by a mobile station constructed pursuant to the IS-2000 standard. The first-type sync channel message is an IS-2000 standard message that has been contracted to make it more compatible with older mobile stations, and has been provided with a field indicating that an additional sync message is also available. The additional sync message may be a full IS-2000 sync message, may include only selected IS-2000 fields, or may include other fields.
