Detailed Description
Currently, when a positioning server positions a geographical position of a multimode mobile terminal supporting an LTE mode, the positioning server needs to position according to positioning information reported by the mobile terminal. However, the positioning information reported by the mobile terminal usually only includes the relevant positioning information of the LTE serving cell and the neighboring cell, and it is difficult for the positioning server to accurately position the mobile terminal only according to the relevant positioning information of the LTE serving cell and the neighboring cell.
In view of the above problems, embodiments of the present invention provide a method for positioning a mobile terminal, where the method enables the mobile terminal to report, when receiving a positioning capability reporting request sent by a positioning server, not only the E-CID capability information of an LTE communication system to the positioning server, but also the E-CID capability information of at least one different system to the positioning server. Therefore, when the positioning server positions the mobile terminal, the positioning server can more accurately position the mobile terminal according to the positioning information of the LTE communication system and the positioning information of at least one different system reported by the mobile terminal.

The method may comprise the steps of;
and 11, receiving a positioning capability reporting request sent by a positioning server.
In specific implementation, the positioning server may be triggered to send the positioning capability reporting request in various ways, for example, the positioning server may be triggered to send the positioning capability reporting request in a way that the mobile terminal sends the positioning request to the positioning server; the positioning server can also be triggered to send a positioning capability reporting request in a manner that the positioning server sends a positioning request to the mobile terminal. That is, both the positioning server and the mobile terminal may trigger the positioning server to send a positioning capability reporting request.
The mobile terminal may generate the positioning request in various ways, for example, the positioning request may be generated by an application program such as map software of the mobile terminal.
In the embodiment of the present invention, the mobile terminal refers to a computer device that can be used in a mobile process, and includes, but is not limited to, a mobile phone, a notebook, a tablet computer, and a vehicle-mounted computer.

Any number of communication modes that can be supported by the mobile terminal is not limited by the present invention, and is within the scope of the present invention.
It should be noted that, in the embodiment of the present invention, the positioning server may be an independent dedicated server, or may provide other services at the same time, for example, a dedicated storage area and a dedicated memory area may be opened on other servers to provide the positioning service. Of course, the positioning server, regardless of the manner in which it is used, may communicate with the mobile terminal.
The mobile terminal and the positioning server may communicate with each other by using a wired connection or a wireless connection. The wireless connection method may include various communication modes such as WiFi, bluetooth, infrared and the like.

In specific implementation, the current communication mode of the mobile terminal is an LTE mode, and the corresponding current communication system is an LTE system. Except the communication system corresponding to the current communication mode, other communication systems supported by the mobile terminal are all different systems. For example, the heterogeneous System may be a Wireless Local Area Network (WLAN), a Global System For Mobile communications (GSM), a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA), a Code Division Multiple Access (CDMA) 2000, or the like.
When reporting the positioning capability information, the mobile terminal can report the positioning capability information of at least one different system besides the positioning capability information of the LTE communication system. The at least one heterogeneous system may be one of heterogeneous systems supported by the mobile terminal, or two or more heterogeneous systems.
