Embodiment Construction

[0025] In a nutshell, the user plane OTDOA positioning method provided by the present invention is to provide the positioning assistance data information of the UE required by the core network positioning control center to the core network positioning control center (for controlling the user plane) through the user plane service data transmission mode. positioning service), so as to realize OTDOA positioning of UE. Additionally, the method can be applied to both distributed and centralized systems.

[0026] Embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be noted that the following embodiments are given to provide a comprehensive and thorough understanding of the present invention, but not to limit the present invention.

[0027] In an embodiment of the present invention, a user plane OTDOA positioning method is provided.

[0028] As shown in Figure 1, the method includes the following steps:

Abstract

The invention discloses a user-interface OTDOA locating method, comprising the steps of: S102. the operation and maintenance system of a kernel network locating control center establishes a base station's geographic information index table, an adjacent cell information index table and a base station index table; S104. the kernel network locating control center obtains RNC ID and CELL IN of UE and then requests the UE to make OTDOA locating measurement; S106. the kernel network locating control center searches the related adjacent cell information in the adjacent cell information index table according to the RNC ID and CELL ID of the UE and sends the related adjacent cell information to the UE; S108. the UE makes OTDOA-related information measurement according to the related adjacent cell information; and S110. the UE or kernel network locating control center makes OTDOA locating according to the measured OTDOA-related information.

Description

technical field [0001] The present invention relates to the OTDOA (Observed Time Deviation Of Arrival, observed time difference of arrival) positioning technology of the TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, Time Division Synchronous Code Division Multiple Access) system in the technical field of wireless communication, and more specifically The invention relates to a user plane observed time difference of arrival positioning method. Background technique [0002] The positioning service is a special value-added service on the mobile network, with great commercial value and rich application types. In the 3G field, due to the improvement of positioning accuracy and the adoption of open architecture, it is very interesting. It is considered that it may be a 3G One of the representative applications. [0003] The positioning service is a wireless value-added service that obtains the location information of wireless users through the wireless communi...
