Problems solved by technology

[0005] After the user completes the positioning, due to positioning accuracy and error problems, it often deviates from the user's real position, and the specific address on the map in the prior art is a fixed point, so the longitude and latitude information obtained by the server according to the positioning of the user terminal is as follows: The specific address selected by the user will also be positioned to an address with a certain deviation from the user's real location due to errors. The user needs to re-adjust and select the specific address to perform subsequent location services, resulting in poor user experience.

Embodiment 1

[0046] see figure 1 , the embodiment of the present invention proposes a method for updating geographic location information, including:

[0047] 101: Receive positioning information uploaded by the terminal;

[0048] 102: Obtain an address sequence set corresponding to the positioning information, and send the address sequence set to the terminal;

[0049] 103: Receive an address uploaded by the terminal and selected by the user according to the address sequence set;

[0050] 104: Update the area range of the address according to the address and all positioning information located to the address, so that the address can be located more accurately according to the positioning information during subsequent positioning.

[0051] The embodiment of the present invention continuously optimizes and updates the range of addresses in the map based on user positioning information and the specific address selected by the user based on the positioning information, and gradually improve...

Embodiment 2

[0053] see figure 2 , the embodiment of the present invention proposes a method for updating geographic location information, including:

[0054] 201: The server receives the positioning information uploaded by the terminal.

[0055] After the terminal performs positioning, it will generate a set of positioning information. The positioning information includes at least the current latitude and longitude information (lat, lon) of the terminal, the current positioning mode information pos_type, and the model identifier model of the terminal to form a set, and the terminal reports the set to the server. The positioning method information pos_tpe is the identification of the positioning method adopted by the terminal. For example, the positioning can be performed through the GPS module of the terminal, and the positioning can be performed through AGPS (Assisted Global Positioning System, assisted global satellite positioning system). The positioning method is not limited here ....

Embodiment 3

[0102] see image 3 , the embodiment of the present invention proposes a server for updating geographic location information, including:

[0103] The first receiving module 301 is configured to receive positioning information uploaded by the terminal;

[0104]An obtaining module 302, configured to obtain an address sequence set corresponding to the positioning information, and send the address sequence set to the terminal;

[0105] The second receiving module 303 is configured to receive the address uploaded by the terminal and selected by the user according to the set of address sequences;

[0106] The update module 304 is configured to update the area range of the address according to the address and all positioning information located to the address, so that the address can be located more accurately according to the positioning information during subsequent positioning.

[0107] In a specific implementation manner, the acquisition module 302 includes:

[0108] A range d...

Abstract

The invention discloses a method and a server for updating geographic location information, and belongs to the field of positioning. The method comprises the following steps of: receiving positioning information uploaded by a terminal; acquiring an address sequence set corresponding to the positioning information, and transmitting the address sequence set to the terminal; receiving an address selected by a user according to the address sequence set from the terminal; and updating an area coverage of the address according to the address and all positioning information positioned to the address, so that the address can be accurately positioned according to the positioning information during subsequent positioning. The area coverage of the address in a map is continuously optimized and updated according to the positioning information of the user and a specific address selected by the user according to the positioning information, so that the problem of lower user positioning accuracy caused by problems of the positioning accuracy and errors is gradually solved.

Description

technical field [0001] The invention relates to the field of positioning, in particular to a method and server for updating geographic location information. Background technique [0002] Under the background of the rapid development of mobile terminals, LBS (Location Based Service, location-based service) is more and more used in people's daily work and life. LBS is a comprehensive application service that integrates GPS (Global Positioning System, Global Positioning System) positioning, mobile communication, navigation and other technologies to provide users with services related to spatial location. [0003] The existing technology is to obtain the location information (latitude and longitude information) of the mobile terminal user through the wireless communication network of the telecom mobile operator (such as GSM network, CDMA network) or external positioning method (such as global satellite positioning system), and send it to the server. With the support of the GIS ...
