SERVER CAPABLE OF PAIRED COMMUNICATION OF N MACHINES AND DECT PRIVATE COMMUNICATION NETWORK INCLUDING THE SERVER

摘要

PROBLEM TO BE SOLVED: To provide the new service via an existing communication network without remodeling the network structure by making a server include a pair of simulators against every pair of machines and also include a means with which every simulator can communicate with another simulator. SOLUTION: A private network PN includes the base stations PBS1-PBS3 of DECT types and a private GSM server SGP in addition to a PABX. The services are supplied by the GSM base transceiver stations BTS1-BTS3, a GSM base station controller BSC and GSM mobile service switching center MSC. The PABX is particularly connected to a fixed public switching telephone network PSTN, and a GSM terminal is available via the PABX and also the PSTN. As a result, the GSM terminal can use all services of the PN including the local calls with which the PABX is integrated and the calls incoming via the PSTN while maintaining the services which are supplied by a GSM network.
