  • METHOD AND DEVICE FOR NOTIFYING A LOCATION SERVICES CLIENT THAT A TARGET TERMINAL IS UNREACHABLE
    Publication number: 20110053606
    Abstract: A method and device enables notifying a location services client that a target terminal is unreachable. The method (400) includes receiving at a location server from the location services client a location reporting request message that requests information about the location of the target terminal (step 405). A positioning session is then established between the location server and the target terminal (step 410). It is then determined at the location server that a location report from the target terminal is overdue (step 420) and that the target terminal is unreachable (step 425). Finally, a notification message is transmitted from the location server to the location services client indicating that the target terminal is unreachable (step 430).
