Abstract
A method of setting up and handing off calls in a mobile cellular radio system in which consideration is given to the load capacity of several types of channels. The communication system determines the available capacity of the different groups of channels in the communication system whenever a new call needs to be set up. The system then assigns the new call to the group of channels with the most available channels if the requesting mobile station is a multi-mode mobile station, or the system hands off a multi-mode mobile station from a first group of channels to a second group of channels or vice versa to create free channels for calls from single mode mobiles.
