Abstract

Abstract A method and system are disclosed for enhanced data transmission within a cellular telephone system having multiple assigned voice channels separated by adjacent buffer voice channels. A data processing terminal (66) is utilized to divide the data stream into multiple relatively short data packets which are then sequentially transmitted (70) within alternate adjacent buffer voice channels. By switching from one adjacent buffer voice channel to a subsequent adjacent buffer voice channel, in a predetermined and repetitive order, as each data packet is transmitted, the amount of interference experienced in any one assigned voice channel is minimized. Synchronization between adjacent data packets may be achieved by either utilizing adjacent buffer voice channels in a predetermined and repetitive order or by concatenating an indication of the next buffer voice channel utilized with each data packet. A synchronization packet may also be included with each data packet to permit synchronization between adjacent data packets at the receiver (72).

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 85 words
A method for enhanced data stream transmission within a cellular telephone system having a plurality of assigned voice channels separated by adjacent buffer voice channels, said method comprising the steps of dividing a data stream into a plurality of relatively short data packets; and sequentially transmitting individual ones of said plurality of relatively short data packets within said adjacent buffer voice channels throughout said cellular telephone system in such a way that successive data packets are transmitted over different ones of said buffer voice channels.
Claim 2
Dependent Claim 26 words
A method as claimed in Claim 1, further including the step of concatenating a synchronization packet with each of said plurality of relatively short data packets.
Claim 3
Dependent Claim 46 words
A method as claimed in Claim 1 or Claim 2, further including the step of concatenating an identification of an adjacent buffer voice channel containing a subsequent one of said plurality of relatively short data packets with each of said plurality of relatively short data packets.
Claim 4
Dependent Claim 71 words
A method as claimed in Claim 1 or Claim 2, wherein said step of sequentially transmitting individual ones of said plurality of relatively short data packets within alternate ones of said adjacent buffer voice channels comprises the step of sequentially transmitting individual ones of said plurality of relativelyt short data packets within selected ones of said adjacent buffer voice channels in a predetermined and repetitive order throughout said cellular telephone system.
Claim 5
Dependent Claim 103 words
A data processing system for data stream transmission within a cellular telephone system having a plurality of assigned voice channels separated by adjacent buffer voice channels, said data processing system comprising processor means for dividing a data stream into a plurality of relatively short data packets; and controllable transmitter means coupled to said processor means for sequentially transmitting individual ones of said plurality of relatively short data packets within said adjacent buffer voice channels throughout said cellular telephone system, said transmitter means being responsive to said processor means to assign different ones of said buffer channels for transmission of successively transmitted data packets.
Claim 6
Dependent Claim 29 words
A system as claimed in Claim 5, wherein said processor means further includes means for concatenating a synchronization packet with each of said plurality of relatively short data packets.
Claim 7
Dependent Claim 49 words
A system as claimed in Claim 5 or Claim 6, wherein said processor means further includes means for concatenating an identification of an adjacent buffer voice channel containing a subsequent one of said plurality of relatively short data packets with each of said plurality of relatively short data packets.
Claim 8
Dependent Claim 50 words
A system as claimed in Claim 5 or in Claim 6 wherein said controllable transmitter means is adapted to transmit individual ones of said plurality of relatively short data packets within selected ones of said adjacent buffer voice channels in a predetermined and repetitive order throughout said cellular telephone system.
Claim 9
Independent Claim 46 words
A system as claimed in any of Claims 5 to 8, further including controllable receiver means coupled to said processor means for sequentially receiving individual ones of a second plurality of relatively short data packets within said adjacent buffer voice channels throughout said cellular telephone system.
Claim 10
Independent Claim 23 words
A system as claimed in any of Claims 5 to 9 wherein said processor means comprises a portable battery powered data processing terminal.
