"CELLULAR COMMUNICATION SYSTEMS FOR COMMUNICATING POSITION INFORMATION OF MOBILE STATIONS IN DISPLACEMENT BETWEEN AT LEAST TWO PUBLIC TERRESTRIAL MOBILE NETWORKS (PLMNS) AND THAT SUPPORTS THE DISPLACEMENT BETWEEN AT LEAST TWO PLMNS, A POSITION SYSTEM WITH A POSITIONING SYSTEM. THE DISPLACEMENT BETWEEN A FIRST PLMN AND A SECOND PLMN, AND, PROCESS FOR COMMUNICATING POSITION INFORMATION RELATED TO A MOBILE STATION IN DISPLACEMENT ON A COMMUNICATION NETWORK "A communication system communicates a request for position and information along a communication channel that is used to communicate travel data between mobile stations. Along the communication channel, a first local PLMN transmits a position request to a second remote PLMN covering a remote service area within which a moving mobile station is positioned. In response to the position request, the second PLMN transmits position information related to the moving mobile station to the first PLMN, preferably along the same communication channel.
