1. A method for error correction processing of a repeat message transmitted to a portable subscriber unit in a messaging system wherein each repeat message may contain errors in different portions of the repeat message, comprising the steps at the portable subscriber unit of:

  • receiving a first copy of the repeat message containing a first set of errors;

    identifying the first set of errors;

    receiving a subsequent copy of the repeat message containing a subsequent set of errors;

    identifying the subsequent set of errors;

    comparing the first set of errors with the subsequent set of errors to eliminate any non-recurring errors in the formation of an error reduced message;

    further correcting the error reduced message as necessary if an nth copy of the repeat message is received and if errors remain in the error reduced message by comparing a set of remaining errors in the error reduced message with an nth set of errors found in the nth copy of the repeat message to eliminate any further non-recurring errors.
