Abstract:
A method of increasing the CDPD data rate between a mobile terminal and a basestation in a digital cellular mobile communications system, comprising:an encoding step comprised of: constructing a CDPD block; assembling an TIA/EIA-136 frame leaving the data fields of the TIA/EIA-136 frame empty; partitioning the CDPD block into CDPD block data bit lengths that can be accommodated by the data fields of the TIA/EIA-136 frame; placing partitioned CDPD block data in the data fields of the TIA/EIA-136 frame; sending the assembled TIA/EIA-136 frame having CDPD block data in the data fields to existing transmission software; and a decoding step comprised of: receiving the TIA/EIA-136 frame comprised of CDPD data in the data fields of the TIA/EIA-136 frame using existing receiving software; re-constructing the CDPD block from the data fields of the TIA/EIA-136 frame; and forwarding the re-constructed CDPD block to existing CDPD upper layer software for further processing.
