Abstract
A system (100) and method (200) for providing a multiple channel site for supporting talk group activity is provided. The method includes determining (202) an arrival time (141) of a plurality of Vehicular Repeater System (VRS) (101-103) to a vicinity (140), identifying (204) talk group activity among the plurality of PSUs (171-176) in the vicinity, and assigning VRSs to talk groups in order of arrival time and talk group activity. A master VRS maintains and updates (322) a list of recently active talk groups (TG), orders (324) the list by frequency of use of a talk group, forwards the list to slave VRSs and PSUs, and allocates (326) single channels in view of the list to the slave VRSs. PSUs in the vicinity can read the assignment list and update their communication channel based on a selected talk group in the list.
