Abstract
A communication system communicates position request and information over a communication channel that is used for communicating roaming data between mobile stations. Over the communication channel, a first local PLMN transmits a position request to a second remote PLMN covering a remote service area within which a roaming mobile station is positioned. In response to the position request, the second PLMN transmits position information related to the roaming mobile station to the first PLMN, preferably, over the same communication channel.
