Problems solved by technology

In practical applications, the fingerprint information of a single user's MR is time-varying, and these three methods do not consider the time dimension, so the accuracy is not high enough
And these three methods increase with the increase in the number of MRs, the amount of calculation and the required storage memory increase
In practical applications, there are a large amount of MR data, and there must be problems of low efficiency and low accuracy when using the above three methods

Embodiment 1

[0075] figure 1 A flow chart of an MR positioning method based on a location fingerprint database according to Embodiment 1 is shown. like figure 1 As shown, the method includes the following steps:

[0076] Step S110: According to the primary cell identification, the adjacent cell identification and the primary cell level value in the MR fingerprint information, the fingerprint records matching the MR fingerprint information are screened out from the preprocessed location fingerprint database; There are multiple corresponding neighboring cells.

[0077] The MR fingerprint information refers to the primary cell information and neighboring cell information of the cell where the user is located and uploaded by the user terminal. The MR fingerprint information specifically includes: the primary cell identifier of the cell where the user is located, the primary cell level value, the adjacent cell identity, the adjacent cell level value, and the primary and adjacent level differ...

Embodiment 2

[0089] figure 2 A flow chart of an MR positioning method based on a location fingerprint database according to the second embodiment is shown. like figure 2 As shown, the method includes the following steps:

[0090] Step S200: Preprocessing the location fingerprint database.

[0091] The location fingerprint database refers to a preset grid data model used to store multiple fingerprint records.

[0092] Specifically, first, each fingerprint record with the same primary cell identifier in the location fingerprint database is grouped according to the primary cell level value in the fingerprint record. In specific implementation, first, the fingerprint records with the same primary cell identifier are stored in the corresponding fingerprint record set, for example, the fingerprint record with the primary cell identifier ID-0 is stored in the corresponding fingerprint record set ID-0. Then, the fingerprint records in the fingerprint record set ID-0 are grouped by the primar...

Embodiment 3

[0132] image 3 Shown is a structural diagram of an MR positioning device based on a location fingerprint database according to Embodiment 3, where the device includes:

[0133] The fingerprint record matching module 31 is adapted to screen out the fingerprint records that match the MR fingerprint information from the preprocessed location fingerprint database according to the main cell identification, the adjacent cell identification and the main cell level value in the MR fingerprint information; wherein , there are multiple adjacent cells corresponding to the MR fingerprint information;

[0134] The candidate primary-neighbor fingerprint record screening module 32 is adapted to calculate the primary-neighbor level difference between the primary cell in the MR fingerprint information and the adjacent cell for each adjacent cell corresponding to the MR fingerprint information, and calculate the level difference between the primary cell and the adjacent cell in the MR fingerprin...

Abstract

The present invention discloses a MR positioning method and device based on position fingerprint library. This method includes: according to the main community logo, neighboring community logo, and main community electrical value in the MR fingerprint information, from the pre -processing position fingerprint library in the fingerprint libraryFilter the fingerprint records that match the MR fingerprint information; for the neighboring communities corresponding to the MR fingerprint information, calculate the flat difference between the main neighbor's electricity, and screen at least two candidate neighbor record records from the matching fingerprint records; the candidate's neighbor will beThe fingerprint records are added to the candidate's neighbor's fingerprint collection; the number of times the number of candidate neighboring fingerprint records, according to the statistical results, screen the target fingerprint record to determine the user location information corresponding to the MR fingerprint information.The present invention can gradually screen the target fingerprint records corresponding to the MR fingerprint information through the main community logo, neighboring community logo, the level of the main community, and the flat differences of the main neighborhood to determine the user location information, thereby increasing the user location information.accuracy.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to an MR positioning method and device based on a location fingerprint database. Background technique [0002] The wireless optimization method based on MR (Measure Report, measurement report) is gradually being promoted in the wireless network. No matter whether the user is outdoors or indoors, the fingerprint database positioning method based on MR data can accurately locate the user's position and truly reflect the user's location. perception. Therefore, the fingerprint database positioning method based on MR data can clearly know the current status of the network, quickly locate the problems in the existing network and deal with them in time, which greatly improves the optimization efficiency; at the same time, it can also find network problems before users and reduce complaints; In addition, the influence of subjective factors of manual planning can be reduced...
