Abstract
An improved two-way radio communication system having a limited number of channels is disclosed which assigns calls in a max-minimum method, in a first embodiment according to the type of call and sector to be served. This disclosed first embodiment includes a method that ascertains the type of call, handoff or first assignment, and assigns a server with a given central controller to a channel frequency within the requestor sector that minimizes interference to present users. The method of the second embodiment controls requests for assignment to a limited number of channels to reduce adjacent channel interference to and from the requestor with respect to present users operating on a system by utilizing one or more thresholds to arrange channel assignments based upon progressively larger or smaller values of received signal strength.
