1. A method of formulating paging messages for transmission to a mobile paging unit, the paging messages being formulated in accordance with a paging protocol having a data link layer, the method comprising the steps of:
- determining the portions of said data link layer that require forward error correction coding as a first portion;
determining the portions of said data link layer that do not require forward error correciton coding as a second portion; and
assigning said first portion of the data link layer segments to be forward error correction coded and said second portion to be unprotected by forward error correction.

Abstract
A method and system for performing optional or selective forward error correction (FEC) on data within the data link layer before the data is transmitted. First, a determination is made as to what data in the data link layer requires to be FEC encoded. Next, the data link layer data determined to require FEC encoding is protected by FEC and the remaining data link layer data is not FEC protected. A data application or any network protocol layer above the data link layer determines the portions required to be FEC encoded.
