Problems solved by technology

Other technologies such as Bluetooth positioning can meet the accuracy requirements, but additional deployment is required, and because the communication distance is relatively short, the deployment cost is relatively high
And at present, when the terminal uses WIFI and Bluetooth positioning methods, its location information is also unknown to the cellular network elements.

[0134] According to the first embodiment of the present invention, a method for locating a mobile terminal on the network side is provided. For network-side equipment, the method for locating a mobile terminal provided by the present invention is implemented, such as figure 1 shown, including:

[0135] Step 101, the cellular network device determines at least one mobile terminal serving as a positioning sensor terminal in the cellular network, and the position of the mobile terminal serving as a positioning sensor terminal is known;

[0136] The location of the mobile terminal described in the embodiments of the present invention is known, which means that the precise location of the mobile terminal is known. The specific method of obtaining the precise location of the mobile terminal is not limited. It can be determined according to the location of the mobile terminal deployed by the network, or according to the reported by the mobile terminal.

[0137] The network here may ...

Embodiment approach 1

[0148] The cellular network device selects at least one mobile terminal from stationary mobile terminals with known locations in the cellular network as the first type of positioning sensor terminal.

[0149] The network may select a mobile terminal with a known location and in a connected state as the first type of positioning sensor terminal; or select a mobile terminal with a known location and in an idle state as the first type of positioning sensor terminal.

[0150] For the first type of positioning sensor terminal, the cellular network device uses an air interface message to send the positioning measurement configuration to the first type of positioning sensor terminal. The measurement type in the positioning measurement configuration is positioning measurement search, which is used to indicate that the mobile terminal is selected as the first type The sensor terminal, and instructs the positioning sensor terminal of the first type to use the near field communication mod...

Embodiment approach 2

[0157] According to the application sent by the mobile terminal that has acquired its own location, at least one mobile terminal is selected from the mobile terminals that have sent the application as the second type of positioning sensor terminal.

[0158] For the mobile terminal as the second type of positioning sensor terminal, which has turned on the near field communication mode, it can use the air interface message to send the positioning measurement configuration to the second type of positioning sensor terminal. The positioning measurement configuration includes the trigger conditions for reporting the measurement report. The positioning The measurement configuration implicitly indicates that the mobile terminal has been selected as a positioning sensor terminal of the second type.

[0159] Preferably, the application sent by the mobile terminal is received through an air interface message, and the air interface message includes identification information of the mobile ...

Abstract

The invention provides a method and a device for positioning mobile terminals. The method comprises the following steps: determining at least one mobile terminal serving as a positioning sensor terminal in a cellular network by cellular network equipment; instructing the positioning sensor terminals by an air interface message to search for mobile terminals to be positioned in a near-field communication mode; and when a measurement report reported by any positioning sensor terminal is received, positioning the mobile terminals to be positioned identified by identification information according to a position of the positioning sensor terminal and the identification information of the mobile terminals to be positioned searched by the positioning sensor terminal in the measurement report, or transmitting the identification information and position information of the determined positioning sensor terminal to the mobile terminals to be positioned in order that the mobile terminals to be positioned are positively positioned. The cellular network and a near-field communication technology are combined to perform positioning, so that accurate positioning of the mobile terminals is realized under the situation of saving the overhead of positioning system deployment, and an accurate position of a user can be acquired by a cellular network element.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for positioning a mobile terminal. Background technique [0002] The accuracy of GPS (Global Positioning System) positioning can be accurate to within 5 meters outdoors, but it usually cannot work normally indoors, and most of the commercial and social activities of human beings take place indoors. With the widespread popularity of smart phones, it can be applied to mobile shopping, mobile e-commerce, personalized advertisements, preferential information, etc. Therefore, indoor positioning is of great significance. At the same time, accurate indoor positioning is also required in terms of public safety. The prospect of indoor positioning will be widespread application. [0003] The current indoor positioning technologies mainly include the following types: [0004] 1) Cellular network positioning technology [0005] Among the existi...
