Embodiment Construction

[0044] In the embodiment of the present invention, after the evolved base station itself is the originating end of the positioning request and successfully allocates SRS resources for the user equipment, it sends a positioning request including UTDOA assistance data to the receiving end of the positioning request. For the eNB as the initiator to trigger the UTDOA positioning process, since the eNB directly carries the UTDOA auxiliary data while sending the positioning related request, it avoids excessive signaling overhead and achieves the purpose of optimizing the signaling process.

[0045] The positioning request initiator in this embodiment of the present invention may be a positioning client or an initiator.

[0046] Among them, the UTDOA auxiliary data in the embodiment of the present invention includes but not limited to part or all of the following information:

[0047] SRS resource, C-RNTI (Cell-Radio Network Temporary Identifier cell wireless network temporary identi...

Abstract

The embodiment of the invention relates to the technical field of wireless communication, in particular to a method and equipment for transmitting positioning information. The method and the equipment are used for solving the problem that the positioning acquisition behavior of an evolved node B (eNB) serving as a positioning request initiator is redundant in a flow to cause the waste of signaling overhead in the prior art. The method in the embodiment of the invention comprises the following steps that: the eNB is determined as the positioning request initiator; and the eNB transmits a positioning request comprising uplink-time different of arrival (UTDOA) auxiliary data to a positioning request receiver after successfully allocating sounding reference signal (SRS) resources to user equipment. For a UTDOA positioning process triggered by the eNB which serves as the initiator, the eNB directly carries the UTDOA auxiliary data at the same time of transmission of the positioning request, so that overmuch signaling overhead is avoided, and the aim of optimizing a signaling flow is fulfilled.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and device for transmitting positioning information. Background technique [0002] If the UE (user equipment) has a GNSS (Global Navigation Satellite System, global satellite navigation) function, such as a global positioning system (Global Positioning System, GPS), it can directly use the GPS to obtain the current position of the UE, which is called standalone GNSS positioning. [0003] Due to the high cost of GPS and the relatively large fading of GPS signals in indoor scenarios, people have proposed a method to obtain the location of the terminal UE based on the mobile communication network, that is, LCS (LoCation Service, positioning service), usually with OTDOA (Observed Time Difference Of Arrival, observation Time difference of arrival positioning method), network-assisted global satellite navigation system positioning method (A-GNSS), UTDOA (Uplink-...
