Abstract  Abstract

for some cells of a cellular telephone system provides a channel number device and method for dynamically mapping to physical frequency for the channel number represents a physical frequency and providing a channel number to a cellular telephone system is the mapping of physical frequency under the condition of use. the method comprising the steps of: providing an information element indicating the dynamic mapping and is performed in a manner compatible with one existing channel number space so as to maintain without changing any existing signaling messages. the method further provides a change in a dynamic mapping: a duplicated mapping is broadcast the channel number of the two group of non-overlapping at least partially mapped to a same frequency block the broadcast is sustained for a predetermined period of time the time period any mobile phone is assumed its length enough to operate in the cell that has been decoded for the mapping of the copying.

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.
