The method of promoting the mobile station position specification which uses terrestial station based cellular network

摘要

The mobile station (22) position specification is promoted with the communication which uses the Radio Frequency spectrum which is used for cellular communication usually. The 1st position specific signal the base station transceiver (30 and 32) with the mobile station (22) is communicated in between, includes the information regarding the position of signal source. The plural 2nd position specific signals, the plural ranging beacon devices of correspondence (40, 42 and 44) with the mobile station (22) are communicated in between, each the ranging beacon device (40, 42 and 44) includes the information regarding position. The mobile station (22) it becomes possible depending upon the 1st and 2nd signal to decide position. With example of disclosure, it is transmitted respectively simultaneously the 1st and 2nd signal base station (30 and 32) and the plural ranging beacon devices (40, 42 and 44) by.
