Protocol conversion and bandwidth reduction technique providing multiple NB+D ISDN basic rate interface links over a wireless code division multiple access communication system

摘要

A technique for integrating services digital network (ISDN) and code division multiple access (CDMA) or other digital wireless communication protocols by a technique that strips off lower protocol layers, such as layers one and two of the ISDN protocol and sending only layer three and above messages over a more efficient wireless protocol.

主权项

1. For use with a digital communication network having a first digital communication path for coupling Integrated Services Digital Network (ISDN) communication signals with a first wireless transceiver at a first site, said first wireless transceiver being operative to conduct wireless communications with a second wireless transceiver at a second site, a method of controlling bandwidth utilization of said network comprising id="REI-00001" date="20150210" the steps ofid="REI-00001" :
(a) in response to establishment of a communication session between said first and second sites, controlling said first wireless transceiver to appear to said first digital communication path as though the bandwidth is continuously available during said communication session for wireless communications between said first and second transceivers, irrespective of thea need to transport ISDN communication signals between said first and second sites; and (b) in the absence of said need to transport ISDN communication signals between said first and second sites, making said bandwidth available for wireless communication by another wireless transceiver of said digital communication network; and looping back synchronizing and maintenance bits on the IDSN link to spoof an ISDN physical layer protocol.
