In wireless, trunked communication systems, mobile radio system access occurs over control chan- nels. The control channels carry most of the control- related messages in the system including, but not limited to: origination requests, channel assignments, power control, time alignment and system resource availability. One of the fixed, limiting mobile radio communications parameters is the rate at which the mobile can transmit and receive data. This parame- ter will be referred to as the "speed" ofthe radio. As with most high-tech devices design, mobile radio design is continually improving. Higher speed radios continue to be developed aher older, slower speed mobile radios have been deployed. Current wire- less, trunked infrastructure does not support the use of mobile radios operating at different speeds. Infrastrcture operators are left with the choice between obsoleting their currently deployed mobile radios, or selling their new customers older technol- ogy radios. This report describes a method of supporting sets of heterogeneous speed mobile radios within a single, wireless, trunked system.
