The first positioning server 20 is configured to send a positioning request to the terminal after determining that the terminal in the multi-connection needs to be located by the second positioning server, and determining the terminal according to the received positioning information from the terminal. position.

In an implementation, the first positioning server determines, according to the cell identifier of the terminal, whether the terminal needs to be located by using the second positioning server. For example, according to the cell identifier of the terminal, when determining that the terminal is in an indoor or building-intensive environment, it is determined that the terminal needs to be located through the second positioning server. If it is determined that the terminal is in an indoor or building-intensive environment, and it is determined that the terminal needs to be located through the second positioning server, the embodiment of the present invention can improve the positioning accuracy of the terminal when it is in an indoor or building-intensive environment.

The cell identifier of the terminal may be reported by the terminal to the first location server.

In an implementation, if the first location server needs to obtain the cell identifier of the terminal, the first location server may trigger the terminal to report;

Correspondingly, the terminal may report the cell identifier to the first positioning server by using a positioning application protocol message.

Manner 1: The terminal performs measurement based on the second positioning assistance information to obtain second measurement information, and uses the second measurement information as the positioning information.

Manner 2: The terminal directly locates the terminal according to the second positioning assistance information, to obtain the positioning information.

Whether the terminal adopts mode one or mode two may be determined according to the indication of the first positioning server. For example, if the first positioning server does not support the function of performing positioning according to the measurement information, the terminal may be notified to adopt mode 2; if the first positioning server supports the function of performing positioning according to the measurement information, the terminal may be notified to adopt mode 1.

There are many ways to notify, for example, one bit information can be carried in a positioning request, 0 means mode 1, and 1 means mode 2.

Preferably, the terminal may return the second positioning assistance information to the first positioning server while returning the positioning information.

Preferably, the terminal may return the positioning information to the second positioning server while returning the positioning information to the first positioning server.
