Frequency changing method between adjacent cells in TDMA telecommunications - using many voice channels changing to new carrier in sequence with signalling channel transfer within same channel sequence

摘要

The signalling channel is divided into two blocks of line separated by N/2 line blocks in the N line blocks multiplexed in the TDMA frame. The first block contains synchronisation information and the second block contains information on the jump sequence. Access is just gained on one carrier, among a number, to which the signalling channel and many voice channels are jumped. When the signalling frequency is changed, synchronisation is obtained and information on the jump sequence is obtained. The signalling channel has sub-channels for signal broadcast, synchronisation, personal calling, short messages, acceptance of access and broadcast data. USE/ADVANTAGE - Mobile assisted hand-over in cellular communications. Communication quality maintained at cell boundary, simpler configuration. Possible lower cost version for slower operation.
