Embodiment Construction

[0069] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0070] The invention discloses a network interface message, which can be established between a serving radio network controller and a base station. The structure of such a network interface message is as follows:

[0071] {

[0072] measurement identification;

[0073] measurement type;

[0074] Measurement signal configuration information;

[0075]}

[0076] The measurement signal configuration information indicates the configuration situation information of the uplink signal of the target mobile phone. In WCDMA (Wideband Code Multiple Access, Wideband Code Division Multiple Access) system, the measurement signal configuration information includes:

[0077] {

[0078] signal frequency;

[0079] signal scrambling code number;

[0080] Signal channel code number;

[0081]}

[0082] For TD-SCDMA (Time Division-Synchronous Code Division Multiple A...

Abstract

The invention discloses a network interface message and a method and a system for multi-base station and arrival angle combined wireless positioning. The method enables the system to acquire signal arrival angles of a mobile phone signal relative to serving base stations and auxiliary base stations at the same time and acquire estimation of the position of the mobile phone. The invention adopts a technical proposal that the method comprises the following steps: a core network sends a positioning request; a serving radio network controller sends a signal arrival angle measurement request; the serving stations measure the signal arrival angels; the serving base stations report signal arrival angle measurement; the serving radio network controller sends signal arrival angle measurement request to at least one auxiliary base station in a format of a network interface information, wherein the network interface information comprises a measurement indicator, measurement type information and measurement signal configuration information which indicates configuration conditions of the uplink signals of the mobile phone; the auxiliary base stations measure the arrival angles; the auxiliary base stations report the signal arrival angle measurement; the serving radio network controller carries out position calculation; and the serving radio network controller reports the results of the position calculation of the mobile phone. The invention is applied in the field of wireless communication.

Description

technical field [0001] The invention relates to a network interface message and a wireless positioning method and system based on base station positioning in a wireless system, in particular to a network interface message and a wireless positioning method and system for positioning by using the angle of arrival between multiple base stations and mobile phones. Background technique [0002] With the development of wireless communication technology, especially after the United States proposed emergency location service requirements, wireless positioning services have attracted more and more attention from the industry. [0003] According to whether mobile phones are required to participate, the collected positioning technologies are mainly divided into two types: mobile positioning technologies that require mobile phones to report information and mobile phone positioning technologies that do not require mobile phones to report information. For the former, the network system ne...
