摘要： A mobile telecommunications system has multiple base stations (10) each defining a miniature service zone (20) and capable of communicating with mobile stations (16) present in the service zone over a radio link. Geographically associated ones of the base stations (10) are spaced apart from each other by an area in which the mobile stations (16) are not responsive to electromagnetic waves (18) on the radio links, whereby the base stations (10) are allowed to share the same frequency for the electromagnetic waves (18). The base stations (10) are accommodated in an on-road vehicle telecommunications network (22) which switches communications to the base stations (10).

JPH01311633A INCOMING CONTROL SYSTEM FOR MOBILE BODY COMMUNICATION SYSTEM 失效

摘要： PURPOSE:To efficiently perform incoming control to a mobile station by performing the incoming control, for example, broadcast communication from an exchange station shown by position information about the mobile station by using a base station in its area and the base station at the end of an area neighboring to the base station. CONSTITUTION:A section station (exchange station) C houses road stations (base stations) (D0-D7) in the station, and is reported from the road stations (D0-D7) about the detection of the mobile station 16 when detected by the road stations (D0-D7) in its area. However, the title system is constituted in such a way that the broadcast communication is performed not only to the road stations (D0-D7) but to the road station in an adjacent area, e.g., a road station A0B1C2D0 at the end of entry of a section station C2 when incoming is connected to the mobile station 16. In such a way, it is possible to reduce the probability of invalid incoming connection to the mobile station and to efficiently perform the incoming control on a targeted mobile station.
