Description

Control network element, positioning system and positioning method

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a control network element, a positioning system, and a positioning method.

Background

In a railway system, a railway crew performs construction on the road, and if a running train cannot confirm that the railway crew is performing construction, the railway crew is greatly dangerous, so that potential safety hazards exist. In order to reduce train operation accidents and guarantee the safety of workers, particularly the safety of constructors in tunnels, the workers need to be positioned and early warned, so that the trains can perform corresponding operations according to the positions of the workers, and safety accidents are avoided.

In the prior art, an AGPS method is mainly used for positioning and warning the staff.

The existing positioning solution needs to interface a positioning server at a BSC (Base station controller), initiate positioning by the positioning server, and notify the result to a mobile station MS, and the system architecture is shown in fig. 1:

the GMLC (Gateway Mobile Location Center) completes processing of the MS Location request by the LCS Client, that is, obtains the longitude and latitude information of the user and returns the information to the LCS Client. The SMLC (Serving Mobile Location Center) main functions include positioning method selection and position calculation based on measurement values provided by the Mobile station or BSC. The LCS client initiates a positioning request and acquires the position information. The Base Transceiver Station (BTS), the BSC, the MSC/VLR (Mobile Switching Center), and the HLR (Home Location Register) are existing network elements of the network, the SMLC is an additional network element for supporting a network Location function, and the GMLC and the LCS client are network elements for supporting selective deployment of the Location function.

Based on the network architecture, the AGPS positioning scheme is that the SMLC is responsible for collecting information related to GPS satellites, and sends acquired GPS assistance data (such as reference position, reference time, ionosphere model, etc.) to the MS to be positioned when positioning is required, so that the MS can more easily search for signals of the GPS satellites, and the MS completes positioning under the assistance of the GPS satellites and feeds back a positioning result to the MSC.

The positioning process based on the network architecture is as follows:

MSC sends positioning Request BSSAP Perform Location Request message to BSC, the message carries positioning method (Location Type) as positioning based on AGPS.

The BSC forwards the location request message from the MSC to the SMLC.

The SMLC receives a Positioning Request sent by the BSC, and sends an RRLP Positioning Capability Request message to the MS through the BSC to Request the MS to report the support Capability.

And after receiving the RRLP Positioning Capability Request, the MS returns an RRLP Positioning Capability Response message, and the SMLC acquires the support Capability of the MS through the message.

The SMLC carries the auxiliary information to the MS through the RRLP Assistance data, and the MS needs to return an RRLP Assistance data Ack after receiving the auxiliary information.

After the SMLC acquires the support capability of the MS, the SMLC determines a positioning algorithm according to the support capability of the MS and the requirement of a network, and then sends an RRLP measurement Position Request message to the MS through the BSC, wherein the message carries auxiliary information such as the positioning algorithm and the like.

The MS acquires the required assistance information and performs AGPS-based location estimation. And returning to the SMLC through an RRLP measurement Position Response message.

After the SMLC acquires the required positioning information, the positioning result is sent to the BSC through a BSSAP-LE Performance Location Response message.

And the BSC sends the positioning result to the MSC in a BSSAP Perform Location Response message to complete the positioning process.

The existing positioning mode needs to be realized by a network side butt joint positioning server SMLC, for the AGPS positioning mode, satellite searching in a tunnel is difficult, the positioning accuracy is general, frequent position updating or call initiating/receiving of a mobile phone is required (a TA channel required for positioning is obtained through a measurement report, and the measurement report is reported during communication or position updating), the positioning accuracy depends on the external environment, and if the external environment is changed or unstable, accurate positioning cannot be realized, so that potential safety hazards are brought.
