REGISTRATION OF A TERMINAL WITH A LOCATION SERVER FOR USER PLANE LOCATION

摘要

Techniques for supporting network-initiated location services for a terminal are described. A location server may not be able to reach the terminal in a normal manner in certain operating scenarios. The terminal may perform registration with the location server if the terminal determines that it may not be reachable by the location server in the normal manner. For the registration, the terminal may identify itself to the location server, instigate mutual authentication of the terminal and the location server, and provide an Internet Protocol (IP) address of the terminal to the location server. The terminal may perform registration with the location server whenever the IP address changes and/or periodically whenever a timer expires. The terminal may set the timer to a value received from the location server. The location server may use the IP address to send messages to the terminal for network-initiated location services.
