Optimized Site Association and Call Initiation in a Wideband Data System

Many data systems (TETRA, Project 25, GPRS) have a dedicated logical control channel or control frequency. In order for a Mobile Station to initiate a call, it must first request, via the control channel or control frequency, a dedicated channel or frequency to place the call: this incurs latency for call initiation. This also dedicates an entire channel or frequency for control which could otherwise be utilized for user plane information. The following proposal presents a method of associating to a site without a dedicated control channel. Assume a wideband system (network) will consist of some number of sites and at least one core server located centrally of all of the sites.
