Problems solved by technology

However, since the longitude and latitude ranges covered by the fan-shaped area are relatively large, the use of the radius fan-shaped area limitation method will lead to a large proportion of invalid base stations retrieved in the fan-shaped area

Embodiment 1

[0058] An embodiment of the present invention provides a base station retrieval method, such as image 3 shown, including:

[0059] S101, to retrieve the Pr 1 ,...,Pr N The mean square error of the distance and retrieval point to Pr 0 The sum of the distances is the search start row key, and the sum of the search start row key and M is the search end row key. Search in the base station database to obtain the base station set.

[0060] Among them, Pr 0 , Pr 1 ,...,Pr N is the preset N+1 reference points, N is a positive integer greater than or equal to 2, M is the radius of the preset target area, and M>0. The reference point is a point at a preset fixed position on the edge of the range to be retrieved, which is much larger than the target area. For example, the range to be retrieved is a certain country, and the target area is an area within M kilometers around a reference point set in a certain city of the country. In practical applications, the N reference points ca...

[0084] S202. Obtain the longitude coordinates and latitude coordinates of the base station.

[0085] S203, according to Pr 0 , Pr 1 ,...,Pr N The longitude coordinates and latitude coordinates of the base station, and the longitude coordinates and latitude coordinates of the base station, respectively calculate the base station to Pr 0 , Pr 1 ,...,Pr N distance.

[0086] S204, calculate base station to Pr 1 ,...,Pr N The mean square error of the distance.

[0087] S205. From the base station to Pr 1 ,...,Pr N The mean square error of the distance from base station to Pr 0 The sum of the distances is the row key to cre...

Embodiment 3

[0118] An embodiment of the present invention provides a base station retrieval device, such as Figure 8 As shown, the base station retrieval device includes: a retrieval unit 31 , a calculation unit 32 and a determination unit 33 .

[0119] Retrieval unit 31, for retrieving points to Pr 1 ,...,Pr N The mean square error of the distance and retrieval point to Pr 0 The sum of the distances is the search start row key, and the sum of the search start row key and M is the search end row key, and the search is performed in the base station database to obtain the base station set; where, Pr 0 , Pr 1 ,...,Pr N is the preset N+1 reference points, N is a positive integer greater than or equal to 2, M is the radius of the preset target area, M>0, and the base station database is based on the base station to Pr 1 ,...,Pr N The mean square error of the distance from base station to Pr 0 The sum of the distances is the database created by the row key. Each record in the base stati...

Abstract

The embodiment of the invention discloses a base station searching method and device, relates to the technical field of communications, wherein all valid base stations in a target area close to a searching point can be correctly searched out and the proportion of searched invalid base stations can be reduced. The specific scheme provided by the invention is as follows: by taking the mean square error of distances between the searching point and any one of reference points Pr1, ..., PrN and the sum of a distance between the searching point and a reference point Pr0 as a searching start row key, and taking the sum of the searching start row key and M as a searching end row key, a base station database is searched to obtain a base station set, wherein a row key included in a log of each base station in the base station set is larger than or equal to the searching start row key and is smaller than or equal to the searching end row key; a distance between each base station in the base station set and the searching point is calculated; according to the distance between each base station in the base station set and the searching point, a first base station is determined from the base station set, wherein a distance between the first base station and the searching point is smaller than or equal to the M. The invention is applied to a process of searching the base station from the massive base station database.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a base station retrieval method and device. Background technique [0002] With the expansion of the wireless network scale, the number of base stations deployed by each telecom operator is also increasing. Usually, the telecom operator will record the information of the base station, including the longitude coordinates, latitude coordinates, location area code, cell identifier and cell name of the base station. [0003] In order to evaluate whether the deployment of base stations in a target area is reasonable, it is first necessary to determine which base stations are in the target area from a large number of base stations. For example, if the target area is within 1 kilometer of a search point with a specific latitude and longitude, it is necessary to quickly retrieve all base stations within 1 kilometer of the search point from a large number of base stations. ...
