Abstract

A method and system are provided for synchronizing wireless communication devices. The method and system involve providing a first unit and a second unit for communication over a wireless communication link. Further, an identical identifier is assigned to the first and second units. Also, a data message is constructed having control data. The data message includes a plurality of data bytes and a portion of the control data corresponds to the identifier. The data message is split into a plurality of message portions and the message portions are transmitted from the first unit to the second unit. The message portions are received at the second unit. Control data from the message portions is assembled to form a control message at the second unit. The identifier portion of the control message is compared with the identifier assigned to the second unit. When the identifier portion of the control message matches the identifier assigned to the second unit, the second unit enters an in-synchronization state. When the identifier portion of the control message is different from the identifier assigned to the second unit, the second unit enters an out-synchronization state. At least one prior control message is searched for the identifier assigned to the second unit when the second unit is in the out-synchronization state. A matching identifier is synchronized with when the matching identifier is found in the prior control messages. When the prior control messages are free of the identifier, the second unit resynchronizes with the first unit.
