Problems solved by technology

These operations can not only make the location information in the database inaccurate, but frequent and large-scale update operations are likely to cause the collapse of the base station location update system, which is not conducive to its stability

Embodiment 1

[0067] figure 1 It is a flow chart of the method for updating the base station location according to the first embodiment. The execution body of the method is the base station location updating system. The updating method of this embodiment is specifically applicable to the situation where the location of the mobile terminal is roughly estimated through the pre-acquired location of the base station.

[0068] Step 101, receiving base station data reported by a mobile terminal, the base station data at least including a base station number and reference location information of the base station. Wherein, the base station number includes a LAC number and a Cell-ID number, the LAC number is a location area code of the base station, and the Cell-ID number is an ID number of a cell covered by the base station.

[0069] There are many methods for the mobile terminal to obtain the data of the base station. For example, the mobile terminal acquires location information of the mobile te...

Embodiment 2

[0079] This embodiment is based on the solution in Embodiment 1. When a base station relocation occurs, the received reference location information may also be outside the first threshold range. At this time, other methods are needed for further discrimination. The second embodiment will describe in detail the method for updating the location information of the base station when the base station relocation occurs.

[0080] The method for updating the location of the base station in the second embodiment also includes:

[0081] When it is detected that the number of reference position information stored in the undetermined buffer reaches the maximum threshold value, a second predetermined algorithm is used to calculate according to each reference position information in the undetermined buffer, and the current position information will be updated according to the calculation result.

[0082] The above steps can be placed before step 101, between step 101 and step 102, and afte...

Embodiment 3

[0088] The third embodiment is further improved based on the first and second embodiments. The method for updating the location of the base station also includes: counting the operation of updating the current location information; when it is detected that the updating frequency exceeds the third threshold according to the count value, sending out an alarm message and interrupting the updating operation.

[0089] The above counting may be performed only for the updating operations of a certain base station according to actual needs, or may be performed for counting the updating operations of a large number of base stations, or may be counted for the updating operations of a certain base station respectively and then aggregated. The above-mentioned last method belongs to the method of comprehensive consideration, which can not only check whether the update operation frequency of a certain base station is within the specified range, but also check whether the update operation fre...

Abstract

The invention discloses a method and a system for updating position of a base station. The method comprises the following steps: receiving a base station data reported by a mobile terminal; detecting if the reference position information is in a first threshold scope; if yes, updating the current position information; and if not, storing the reference position information into a to-be-determined cache region. The system comprises a receiving module, a detecting module, a first calculating module and a data updating module, wherein the receiving module is used for receiving the base station data reported by the mobile terminal; the detecting module is used for detecting if the reference position information is in the first threshold scope and supplying the reference position information to the first calculating module or the to-be-determined cache region according to a detection result; the first calculating module is used for calculating by the using of a first predetermining algorithm according to the reference position information and the stored current position information of the base station and supplying a calculation result to the data updating module; and the data updating module is used for updating the current position information according to the acquired calculation result. By the using of the method and system for updating position of base station provided by the invention, the operation of malevolently distorting the position of the base station in the data can be avoided.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a base station position updating method and system. Background technique [0002] With the development of wireless communication technology and the improvement of data processing capabilities, the service based on the location of mobile terminals has become one of the most promising mobile network services. Whether in an indoor or outdoor environment, the demand for quickly and accurately obtaining location information of a mobile terminal and providing services for obtaining location information has become increasingly urgent. [0003] Most of the current mobile terminals adopt two positioning methods: global positioning system positioning (GPS) and mobile network-based base station cell positioning. The positioning method using the global positioning system mainly calculates the position of the mobile terminal by receiving the satellite signals of the global positio...
