Abstract

In today's wide area communications systems, channel and service resources are assigned to com- munications users through standard resource allo- cations methods and algorithms. These algorithms do not necessarily minimize the resource usage within a talkgroup; nor do they provide a method to choose site registration due to available service; nor do they provide methods to mirror the site choices of a target radio. These shortcomings limit the optimization of system channel resources especially when users are in coverage overlap areas, where mul- tiple sites are viable. These problems are highlighted below where communications unit A is in the same talkgroup as Units B and C. Communication Unit A has also been assigned to follow the "Candidate Unit" wherever it may go.

SOLUTION

  These problems can be solved by the methods described here. Prior to site selection, communica- tions Unit A will qua@ each site using today's meth- ods to determine which sites provide acceptable Sig- nal Strength Values. Given that the communications unit typically resides in the dispatch mode, the unit should wish to register at the site where the major- ity of his currently selected talkgroup members are affiliated. The unit will query the central database

as to which site has the most (or all) of the mem- bers of the currently selected talkgroup. The com- munication unit will register on that site ifpossible. Otherwise the communications unit will revert to the standard preferred site list. In the above case, Comm Unit A will chose to register on Site A. This method minimizes the resources used for a talkgroup call by minimizing the number of site brought up for that call.

The second method rela...
