Problems solved by technology

[0004] However, in the positioning method based on Cell-ID, the UE may be located anywhere in the cell, and the accuracy of positioning the UE depends on the radius of the cell where the UE is located. Since the distance of the cell radius is generally large, the Cell-ID The accuracy of the positioning information obtained by the positioning method is not high, which cannot meet the needs of users
Especially in places with low base station density, for example, the cell radius in remote areas will be much larger than that in urban areas, and the accuracy of positioning information obtained through the Cell-ID positioning method will be even worse.

no. 3 approach

[0036] refer to image 3 , the following introduces the third embodiment of the present invention, regarding a UE positioning method, including:

[0037] Step 301: The source cell performs positioning coordination with neighboring cells.

[0038] The source cell configures the UE for measurement and requires the UE to report information about adjacent cells, and the source cell determines an adjacent cell suitable for measuring the location of the UE based on the information about adjacent cells reported by the UE. Then, the source cell requests the neighboring cells suitable for measuring the position of the UE to coordinate and locate the UE. If the neighboring cells agree, the source cell and the neighboring cells will confirm a dedicated preamble.

[0039] Step 302: The source cell sends a positioning measurement command to the UE.

[0040] The source cell sends a positioning measurement command to the UE, requiring the UE to measure the positioning measurement information...

no. 4 approach

[0046] refer to Figure 4 , introducing the fourth embodiment of the present invention, regarding a UE positioning method, including:

[0047] Step 401: The source cell sends a positioning measurement command to the UE.

[0048] The positioning measurement command requires the UE to measure the receiving moment of the downlink signal of the adjacent cell. At the same time, the source cell can ensure that the UE is in the "idle state" for a subsequent period of time by configuring an appropriate discontinuous reception DRX cycle, and perform cell synchronization with the adjacent cell. and preamble sending. The specific downlink signal may include: MIB, that is, PBCH information, or downlink synchronization signaling.

[0049] Step 402: After receiving the positioning measurement command, the UE acquires the time difference information of system frame numbers of adjacent cells.

[0050] In the LTE system, the physical broadcast channel (Physical Broadcast Channel, PBCH) cont...

no. 5 approach

[0064] refer to Image 6 , the following introduces the fifth embodiment of the present invention, regarding a UE positioning method, including:

[0065] Step 601: The source cell performs positioning coordination with neighboring cells.

[0066] The source cell configures the UE for measurement and requires the UE to report information about adjacent cells, and the source cell determines an adjacent cell suitable for measuring the location of the UE based on the information about adjacent cells reported by the UE.

[0067] Then, the source cell requests coordinated positioning of the UE from these neighboring cells suitable for measuring the UE's position. The source cell negotiates a common dedicated preamble with the neighboring cell, and the moment when the UE sends the preamble, the negotiation process may be: the source cell sends a request message to the neighboring cell, and the request message may optionally carry one or more Proprietary preamble and the moment when...

Abstract

The invention relates to the wireless communication technical field, and discloses a user facility positioning method, the method comprises: transmitting a positioning measurement command to a user facility; acquiring positioning measurement information which includes timing advance information or system frame number time difference information; and positioning the user facility according to the positioning measurement information. The invention also provides a communication device. According to the scheme of the invention, the user facility can be conveniently and effectively positioned with low cost, thereby facilitating the application of user facility positioning services.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a user equipment positioning method and a communication device. Background technique [0002] With the development of wireless communication technology, the positioning service has become an important service in the wireless communication system. At present, a positioning technology widely used in wireless communication systems is a positioning technology based on a Cell Identity (Cell-ID). [0003] According to the positioning technology based on Cell-ID, the location of the user is determined by the Cell-ID of the cell where the user equipment (UE) is located, as long as the system can collect the geographic location of the base station on the map of the cell where the UE is located, and the location of the cell coverage radius, the system will know which cell the UE is in after the mobile station registers in the cell, so as to realize the positioning of the UE. ...
