Embodiment approach

[0320] As an optional implementation manner, the sending the plurality of PRS measurement results and the plurality of downlink C-PRS measurement results to the positioning server includes:

[0321] sending a report message to the positioning server, where the report message includes the plurality of PRS measurement results and information elements for reporting the downlink C-PRS measurement results, wherein the information elements include the downlink C-PRS measurement results.

[0322] Wherein, the aforementioned reporting message may be a reporting message defined in the current positioning protocol for reporting PRS measurement results. For example, in this embodiment, the downlink C-PRS measurement result (for example: downlink C-PRS-CP measurement value) may be and other positioning measurements (such as at least one of RSTD and RSRP) are reported to the positioning server or base station of the network for high-precision positioning of the user terminal. The reporting ...

Abstract

The embodiment of the invention provides a positioning method and related equipment, and the method comprises the steps: a user terminal measuring positioning reference signals PRS sent by a pluralityof positioning reference devices, and obtaining a plurality of PRS measurement results; the user terminal measuring the downlink C-PRS sent by the plurality of positioning reference devices to obtaina downlink C-PRS measurement result; the user terminal performing positioning operation according to the plurality of PRS measurement results and the downlink C-PRS measurement results; wherein the positioning operation comprises the following steps: sending a plurality of PRS measurement results and downlink C-PRS measurement results to a positioning server, so that the positioning server determines the position of the user terminal according to the plurality of PRS measurement results and the downlink C-PRS measurement results; or the positioning operation comprising: the user terminal determining the position of the user terminal according to the plurality of PRS measurement results and the plurality of downlink C-PRS measurement results. According to the embodiment of the invention, the positioning accuracy of the user terminal can be improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a positioning method and related equipment. Background technique [0002] At present, a variety of user terminal positioning methods are defined in the communication system, such as: observed time difference of arrival positioning method (observed time difference of arrival, OTDOA), enhanced cell identification positioning method (Enhanced-Cell Identification, E-CID) and uplink arrival Time difference positioning method (Uplink observed time difference of arrival, UTDOA) and so on. These methods mainly determine the position of the user terminal by measuring the reference signal of the wireless communication network itself, rather than based on the external reference signal of the wireless communication network. However, the definition methods defined in the current communication system all have the problem of relatively low positioning accuracy. Contents of the...
