Abstract
The invention involves a proactive shift of a control channel among a range of available channels in a mobile radio network, particularly traffic channels. The control channel is intermittently shifted in a periodic or non-periodic manner, thereby making the frequency available for use in other networks. A round-robin process may be used to re-allocate the control channel among traffic channels. This is useful in a network operating within a common channel environment where activity on a fixed the control channel can be unfair or interfere with other networks.

11. A method of re-allocating a control channel in a radio base station, including:
-
selecting an existing traffic channel to become a new control channel according to a predetermined process;
denying new requests by mobile radios over a current control channel for access to traffic channels;
completing existing requests by mobile radios over the current control channel for access to traffic channels;
allocating the selected traffic channel as the new control channel and the current control channel as a traffic channel; and
receiving new requests by mobile radios over the new control channel for access to traffic channels. - View Dependent Claims (12, 13, 18, 19, 20)
