Abstract
A system for communicating multiple page messages or pages via a forward overhead control channel (FOCC) of a cellular network control channel to a cellular-compatible receiving device and combining the data obtained from each received page to form an aggregate message comprising a data sequence. A cellular communications device operating in a normal state responds to a page received via the FOCC by comparing the received page to one or more masks maintained in its memory. If the received page contains a predetermined characteristic and matches a corresponding mask maintained by the receiving device, then it responds by transitioning from a normal state to a receive device identifier state. In the receive device identifier state, the cellular communications device monitors the FOCC for a page having a special identifier assigned to that device. Each received page is compared to a mask corresponding to the special identifier and maintained in memory of the selected device. In response to a match, the cellular communications device transitions from the receive device identifier state to a receive data state and operates to monitor the FOCC for pages containing commands. In the receiv…
