NETWORK-INITIATED METHOD OF POSITIONING IN THE MOBILE COMMUNICATION SYSTEM, INITIATED BY THE EVENT IN THE ZONE, FOR THE TERMINAL IN ROAMING

摘要

1. The network-initiated positioning method in a mobile communication system initiated by an event in a zone for a terminal in roaming, containing the steps:! sending the first server to the terminal, while roaming, messages about the initiation of a communication session to start an initiated session; ! receiving a message about the beginning of a session from a terminal in roaming; ! request from the second server zone identifiers related to positioning triggered by an event in the zone, and obtaining zone identifiers; ! the direction to the terminal while roaming, the response message of the session, including at least the initiating parameter; ! receiving from the terminal while roaming, a message about the initiation of positioning and transmitting it to said second server; ! receiving the estimated location value of the terminal while roaming from said second server and forwarding said received location value to the terminal while roaming; and providing the estimated location value received from the roaming terminal to the agent. ! 2. The method according to claim 1, in which the first server sends the zone identifiers received from the second server to the terminal in roaming by means of a response message from the session. ! 3. The method according to claim 1, in which the message about the initiation of the session contains at least information about the type of initiation. ! 4. The method according to claim 3, in which information about the type of initiation indicates the type of initiation by an event in the zone. ! 5. The method according to claim 1, in which the initiating parameter contains at least the type of change zone "change_area" related to positioning, and
