Method and apparatus for simulcasting within a communication system

摘要

A method and apparatus for simulcasting within a communication system is provided herein. During operation, each base site will be equipped with a plurality of radios capable of transmitting on various frequencies. Base sites within the communication system will be capable of communicating on a predetermined number of channels, which may differ among base sites. A number of channels will be shared by the base sites. When a simulcast is desired, the participants are located, and a common channel is determined for communication. Thus, call participant location information is used to determine the best channel to use to meet the group's coverage needs.

主权项

1. A method for setting up a simulcast call within a communication system, the method comprising the steps of:
receiving at a network controller, a request to set up the simulcast call; determining by the network controller, radios that will participate in the simulcast call; determining locations for radios participating in the simulcast call; determining a same common channel among base sites participating within the simulcast call, wherein; each base site participating within the simulcast call will be equipped with a number of radios (BR), at least two participating base sites will have different channels from each other; each BR capable of utilizing only a single channel for communications, and wherein a first base site participating within the simulcast call will be equipped with a first number of BRs, and a second base site participating within the simulcast call will be equipped with a second number of BRs, and wherein the first and the second base sites use a first and a second BR to participate in the call, and wherein the first and the second BR use the same channel for a downlink simulcast transmission; and instructing the base sites participating in the call, having the common channel, to set up the call using the common channel among base sites participating within the simulcast call.
