A METHOD OF GLOBAL SYSTEM FOR MOBILE COMMUNICATIONS NETWORK AND CODE DIVISION MULTIPLE ACCESS NETWORK UTILIZING THE SAME BASE STATION

摘要

A method of GSM network and CDMA network utilizing the same Base Station, the method comprises following steps: 1) sets mobile switching node (MSN) between the GSM core network and the primary Base Station (BS) of CDMA network, and establishes the connection between MSN and CDMA mobile switching center; 2) MSN adopts multi-signaling points technique, transmits speech path and signaling between MSN and CDMA Base Station, and transmits signaling between MSN and mobile switching center (CMSC); Through primary connection, the signaling is transmitted between the said CDMA Base Station and CMSC. This invention realizes GSM network and CDMA network utilizing the same Base Station apparatus, reduces the cost of establishing network, and improves the utilizable efficiency of system resource. If BS enlarges latter, GSM and primary CDMA both can share the enlarged network overcast.
