Abstract  Abstract

An apparatus and method for providing a dynamic mapping of channel numbers to physical frequencies for some cells of a cellular telephone system for use in case of a cellular telephone system representing physical frequencies by channel numbers and providing a fixed mapping of channel numbers to physical frequencies. The method includes a step of providing an information element indicating the dynamic mapping and is performed in a way that is compatible with an existing channel numbering space thereby keeping unchanged any existing signaling messages. The method also provides for a change in a dynamic mapping: a duplicated mapping is broadcast in which two non-overlapping sets of channel numbers are both mapped at least in part to a same frequency block the broadcasting being continued for a predetermined time assumed to be of sufficient extent that any mobile phones operating in the cells will have decoded the duplicated mapping.
