Problems solved by technology

[0017] The existing positioning method needs to be connected to the positioning server SMLC on the network side. For the AGPS positioning method, it is difficult to search for satellites in the tunnel, and the positioning accuracy is average, and requires the mobile phone to frequently update the location or initiate/accept calls (the TA channel...

Embodiment Construction

[0103] The following combination figure 2 The shown embodiment describes in detail the specific structure of the control network element that can achieve precise positioning without relying on the external environment:

[0104] It should be clear that this embodiment does not limit what kind of device the control network element is, as long as the control network element provided in this embodiment can realize accurate positioning without arranging a positioning server, for example, the The control network element can be a BSC (Base station controller, base station controller), and for example, the control network element is a BSC external cell broadcast server, and for example, the control network element is an RNC (Radio Network Controller, radio network controller) .

[0105] In this embodiment, description is preferably made by taking the control network element as the BSC as an example.

[0106] The control network element includes:

[0107] The first receiving unit 2...

Abstract

The present invention provides a control network element, a positioning system, and a positioning method. The control network element comprises: a first receiving unit, used for receiving call information sent by a mobile wireless device; a first determining unit, used for determining target broadcast information corresponding to the call information satisfying a preset condition; a second determining unit, used for determining a first cell and a second cell according to the call information; and a sending unit, used for sending the target broadcast information to the target mobile wireless device. The control network element provided in an embodiment of the present invention can perform positioning according to call information sent by a wireless mobile device to be positioned, a GPS of the mobile wireless device to be positioned does not need to be acquired and further, a positioning server does not need to be deployed, and accordingly, cost of deploying the positioning server is reduced; the positioning can be performed by directly using the call information, the positioning efficiency can be effectively improved, demands of a user can be satisfied, and the precision of the positioning is effectively ensured.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a control network element, a positioning system and a positioning method. Background technique [0002] In the railway system, railway workers are on the road for construction. If the train cannot be sure that the railway workers are working, it will cause great danger to the railway workers, so there are potential safety hazards. In order to reduce train operation accidents and ensure the safety of construction workers, especially the safety of construction workers in tunnels, it is necessary to locate and warn the construction workers so that the train can perform corresponding operations according to the position of the construction workers to avoid safety accidents. [0003] In the prior art, in order to locate and warn construction workers, the AGPS method is mainly adopted. [0004] The existing positioning scheme needs to be connected to the positioning serv...
