Embodiment 1

[0054] As shown in Figure 6, it is a schematic flow diagram of obtaining location information when the mobile terminal exchanges information with the BS. The network side sets the location information corresponding to the cell in the BS. The corresponding location information of the cell is sent to the mobile terminal.

[0055] As can be seen from the figure, it mainly includes the following steps:

[0056] Step 601, the mobile terminal sends a request message to the BS, requesting cell location information of the cell where the mobile terminal is located;

[0057] Step 602, the BS sends the location information corresponding to the cell to the mobile terminal.

[0058] The BS obtains the corresponding location information of the cell according to the setting information, carries it in the response message, and sends it to the mobile terminal.

[0059] The mobile terminal acquires the corresponding location information of the cell in the response message, and performs subseq...

Embodiment 2

[0061] The network side can set cell corresponding location information on the MSC, and when the mobile terminal exchanges information with the MSC, the MSC sends the cell corresponding location information of the cell where the mobile terminal is located to the mobile terminal.

[0062] The mobile terminal requests the network side through the request message for the cell corresponding location information of the cell where it is located, as shown in Figure 7, which mainly includes the following steps:

[0063] Step 701, the mobile terminal sends a request message to the BS, requesting the location information corresponding to the cell of the cell where the mobile terminal is located;

[0064] Step 702, the BS forwards the request message to the MSC;

[0065] In this solution, the BS does not store the location information corresponding to the cell, and needs to acquire the location information corresponding to the cell from the MSC.

[0066] Step 703, the MSC obtains the co...

Embodiment 3

[0070] In the second embodiment, the MSC does not distinguish the mobile terminal information, and provides the corresponding location information of the cell to all mobile terminals requesting the location information. It is also possible to use the MSC to judge whether the mobile terminal has the right to obtain the corresponding location of the cell according to the subscription information of the mobile terminal. The scheme for differentiated treatment of information, as shown in If 8, is a schematic flow chart of the scheme, as can be seen from the figure, mainly includes the following steps:

[0071] Step 801, the mobile terminal sends a request message to the BS, requesting the location information corresponding to the cell of the cell where the mobile terminal is located;

[0072] Step 802, the BS forwards the request message to the MSC;

[0073] Step 803, the MSC determines whether the mobile terminal has the right to obtain the corresponding location information of t...

Abstract

The method comprises: at network side, setting the location information corresponding to the cell in the cell information; when mobile terminal interacts information with network side, the location information of the cell where the mobile terminal locates at is transmitted to the mobile terminal.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a mobile terminal positioning method and system. Background technique [0002] With the rapid development of wireless communication systems, there are more and more mobile users, and different mobile users have different requirements for wireless communication systems. The function of mobile terminal positioning has been used by more and more people, and the application is becoming more and more The more widely, it has become a very important function in the existing wireless communication system. [0003] In the existing wireless communication system, the positioning service of the mobile terminal needs to be initiated by the user or the positioning terminal when needed. to locate. These positioning technologies all have a certain time delay without exception. In reality, mobile users often hope to know their location in real time. For example, when traveling or ar...
