FIG. 1 is a schematic flowchart of a client positioning method provided by Embodiment 1 of the present invention. The method is applicable to the situation that the user needs to locate outdoors or indoors, and can be executed by a positioning device configured on a positioning server, and the device can be realized by software and/or hardware. Referring to Figure 1, the positioning method provided in this embodiment specifically includes the following operations:

S110. Determine the positioning basis information within the set position range;

In the offline positioning technology, the positioning server pushes the positioning reference information to the client in advance and stores it, and sends updated positioning reference information according to the user's request or the update period set by the server. When receiving a positioning request, the client can perform positioning based on the positioning basis information sent by the positioning server in advance, without sending a positioning request to the server, and return the positioning result to the user after the positioning is successful. However, due to the large amount of data of the full positioning basis information and the limitation of the storage capacity of the client, the positioning server cannot push the full amount of positioning basis data to the client for use. Therefore, some location ranges can be selected to be set, and the positioning reference information within these set location ranges is sent to the client for use by the client for positioning.

The set location range may be the range where the user frequently moves, so as to ensure that the client has a high positioning success rate when performing positioning based on the positioning basis information within the set location range. Specifically, the user's resident location may be analyzed based on the full amount of positioning basis information and user information, and may be used as the set location. Wherein, the user information includes working time information and/or rest time information of the user.

For example, the resident location can be determined through the user's working time information and/or rest time information. Generally, the user is often in a certain location range within the working time information and/or rest time information segment, which can be based on the full amount of positioning information, The user's working time information and/or information time information analyzes these location ranges, deduces these location ranges as the user's office location, residence, or the road section from work location to residence, and then takes these location ranges as the user's permanent location , preparing the positioning basis information near the range of the permanent location, and pushing the positioning basis information to the user terminal for storage so that the user can use it when locating.

It is also possible to analyze the resident location of the user during the holiday period. Generally, the probability of a user traveling during the holiday is relatively high. Based on the user information, the location range of the shopping malls, restaurants, and amusement places that the user frequents during the holiday is analyzed, and these location ranges are calculated. As the user's home location area. Alternatively, location areas where the user frequently uses the positioning function are analyzed based on the location log, and these location area ranges are used as the user's resident location area.

Wherein, the positioning basis information includes WIFI information and/or base station information.

In the base station positioning technology, the positioning platform can receive the geographic location information of the base station sent by the network management system of the communication network, and then, the positioning platform can establish the correspondence between the global cell identification code (CGI, CellGlobalIdentifier) corresponding to the base station and the geographic location information. Mapping relations. Wherein, the geographic location information of the base station is obtained by the base station using a Global Positioning System (GPS, Global Positioning System).

In the wireless fidelity (WIFI, Wireless Fidelity) positioning technology, by selecting some reference anchor points in the area to be positioned in advance, and collecting received signal strength values (RSSI, Received Signal Strength Indication) from different wireless access points at these reference position points, The coordinates of the reference point and the collected RSSI data are stored in the database. Since the coordinates of the reference point are known, a location fingerprint database associated with the physical space and the signal space is established. According to the positioning request of the client, the positioning server uses relevant matching algorithms to match with the fingerprint database to perform positioning.

The positioning basis information is related to the positioning technology used by the positioning platform. For example, when the positioning platform uses WIFI positioning, the positioning basis information can be WIFI information, such as WIFI location fingerprint database and other information; when the positioning platform uses base station positioning, the positioning basis information can be Base station information, such as the CGI of the base station, the geographic location of the base station, and the mapping relationship between the CGI of the base station and the geographic location. When WIFI positioning and base station positioning are used in combination, the positioning basis information may include WIFI information and base station information.

Of course, if the positioning system uses other positioning technologies, the positioning basis information will be different, which is not limited in this embodiment. For example, when using Bluetooth positioning, the positioning basis information may be fingerprint database information related to Bluetooth.

S120. Push the positioning reference information within the set location range to the user's client for storage, so as to instruct the client to perform positioning according to the positioning reference information.

For different users, the positioning server pushes the positioning basis information within the determined set location range to the user's client for storage, so that when receiving the user's positioning request, the client uses the positioning basis data for positioning.

The technical solution provided by this embodiment firstly analyzes the user's resident location based on the full amount of positioning basis information and user information, and determines the positioning basis information within the range of the resident location, and pushes the determined positioning basis information to the user's client for further processing. Storage, to ensure that the client can perform positioning offline according to the positioning basis information, so as to save the computing resources of the positioning server.

Referring to Figure 2, the positioning method provided in this embodiment specifically includes the following operations:

S210. Receive and store the positioning basis information within the set location range pushed by the positioning server;

Wherein, the set location is preferably the resident location of the user.

S220. When a positioning request is received, perform positioning according to the positioning basis information;

When receiving a positioning request, the client uses the stored positioning basis data to perform positioning. Specifically, it can scan and obtain WIFI information and/or base station information according to the user's positioning request, and combine the scanned and obtained WIFI information and/or base station information with the stored The positioning is based on information matching, and positioning is performed according to the matching results. At this time, a series of positioning operations are performed through the client, and the positioning server basically does not participate in positioning operations, which can save computing resources of the positioning server.

S230. Return the positioning result to the user.
