  • System for correlating RF usage in a trunked communication network based on channel assignments and channel drops for each call
    Patent number: 5483575
    Abstract: A system and method are disclosed for correlating rf communications in a multi-site, trunked rf communication system which includes a plurality of site controllers for controlling radio unit rf communications in corresponding geographical site areas and at least one multi-site coordinator for monitoring messages from each site controller and establishing and removing rf communication channels. Information from the multi-site coordinator including channel assignments and channel drops generated for each communication originated from or received by each radio unit is obtained from the multi-site coordinator. RF communication resources used by each radio unit are then correlated and used to generate bills detailing for each radio unit specific instances and types of rf communication resources used.
