Embodiment Construction

[0083] The present invention will be further described below in conjunction with the drawings and embodiments.

[0084] Figure 5 Shows the flow of the preferred embodiment of the method for performing wireless positioning through the update of the auxiliary base station of the present invention. See Figure 5 , The following is a detailed description of each step in the wireless positioning method.

[0085] Step S400: Determine a set of effective auxiliary base stations.

[0086] The neighboring cell of the serving cell where the target mobile phone is located is S, the effective auxiliary base station set is S1, and the remaining base stations in the neighboring cell S that do not belong to the effective auxiliary base station set S1 constitute the set S2. The effective auxiliary base station set S1 here is all or part of the base stations in the neighboring cell S of the serving cell where the target mobile phone is located.

Abstract

The invention discloses a method and a system for wireless positioning by updating of auxiliary base stations, which can be timely and effectively applied to auxiliary base stations with wireless positioning. The method adopts a technical proposal that the method comprises the following steps: a, determining a set S1 of effective auxiliary base stations and a set S2 of base stations excluding effective auxiliary base stations in the set S1 in a neighbor cell S of a service cell in a target mobile phone; b, carrying out primary wireless positioning of the target mobile phone; c, judging whether the wireless positioning is finished or not, if yes, completing the process, otherwise, carrying out next step; d, updating the set S1 of the effective auxiliary base stations; and e, carrying out secondary wireless positioning of the target mobile phone and returning to the step c. The invention is applied in the field of wireless communication.

Description

Technical field [0001] The present invention relates to a wireless positioning method and system, in particular to a wireless positioning method and system for performing joint angle measurement of multiple base stations by means of an auxiliary base station update. Background technique [0002] With the development of wireless communication technology, especially after the United States put forward the emergency location service requirements, wireless location services have attracted more and more attention from the industry. [0003] According to whether mobile phones are required to participate in classification, the collected positioning technologies are mainly divided into two types: mobile phone positioning technologies that require mobile phones to report information and mobile phone positioning technologies that do not require mobile phones to report information. In the former, the network system needs to notify the mobile phone through signaling, and the mobile phone nee...
