    Description


    [0001] The present disclosure claims priority to Chinese Patent Disclosure No. 201610113493.9, filed on February, 29, 2016 and entitled "LOCATION-BASED SERVICE IMPLEMENTING METHOD AND APPARATUS".

    TECHNICAL FIELD



    [0002] The present disclosure relates to the field of communications technologies, and in particular, to a location-based service implementing method and apparatus.

    BACKGROUND



    [0003] With the rapid development of Internet technologies, a growing number of service providers provide users with geographic location-based services, such as searching for a nearby restaurant or parking lot based on a current location.

    [0004] In related technologies, when the geographic location-based service is provided, a region that a requesting location belongs to is usually first determined based on the GeoHash algorithm, and then a service needed by the user is searched for based on the determined region. However, in the GeoHash algorithm, a latitude and a longitude are encoded through a dichotomic search, and the sizes of the regions with different encoded latitudes are different. Because the size of a low-latitude region is greater than the size of a high-latitude region, considerable processing resources of a server are wasted when processing a service in the low-latitude region.
    US Patent Publication No. 2013/054647 to Terauchi, dated 28 February 2013, discloses an information processing method that includes the operations of generating a search reference point geohash indicative of a grid including a search reference point specified by latitude/ longitude information; setting a primary search range at least including the grid represented by the generated search reference point geohash by use of a geohash; searching the primary search range for the search object by referencing a database configured to manage latitude/ longitude information and a geohash as positional information about search objects; setting a secondary search range formed by a grid with the search reference point at the center thereof by use of latitude/longitude information; and searching the secondary search range for the search object.

    SUMMARY



    [0005] The invention is defined by a method according to claim 1 and an apparatus according to claim 5. Further embodiments are defined by the dependent claims. Because all level-2 regions are of the same size, processing a service in a low-latitude region can save processing resources of a server, and improve performance of the server.

    [0010] FIG 1 is a flowchart illustrating a location-based service implementing method, according to an implementation of the present disclosure.

    [0011] Referring to FIG 1, the location-based service implementing method can be applied to a server, and includes the steps below.

    [0012] Step 101: Determine, based on a requesting location in a service request, a level-1 region that the service request belongs to.

    [0013] In this implementation, the service request is a request for obtaining a service object based on a location, and the service object includes a service provider, a service provided by the service provider, etc. The service request is usually initiated by a user, for example, the service request can be a request for searching for a restaurant, a parking lot, etc. near a current location.

    [0014] In this implementation, the level-1 region is usually divided by a developer in advance, for example, the developer can divide continent areas on the earth into a plurality of level-1 regions based on a predetermined size. The Chinese mainland is used as an example. The developer can divide the Chinese mainland into a plurality of level-1 regions based on a size of 0.5° x 0.5° (longitude x latitude).

    [0015] In this implementation, after the service request is received, the requesting location included in the service request can be obtained, and the level-1 region that the service request belongs to is determined based on the requesting location. The requesting location is usually represented in a form of latitude and longitude coordinates. For example, assuming that the Chinese mainland is divided into a plurality of level-1 regions based on a size of 0.5° x 0.5° (longitude x latitude), and the requesting location lies at longitude 110.1° east and latitude 28.2° north, in this step, referring to FIG. 2, it can be determined that the service request belongs to a level-1 region whose southwest coordinates are longitude 110° east and latitude 28° north and northeast coordinates are longitude 110.5° east and latitude 28.5° north.

    [0016] Step 102: Divide the level-1 region into a plurality of level-2 regions based on predetermined granularity.

    [0017] In this implementation, the predetermined granularity can be set by the developer. For example, the developer can set the predetermined granularity to, for example, 50 meters or 100 meters based on a requirement for service granularity in actual disclosure. No limitation is imposed in the present disclosure.

    [0018] Based on step 101, after the level-1 region that the service request belongs to is determined, the level-1 region can be divided into a plurality of level-2 regions based on the predetermined granularity. Referring to FIG 3, the dividing the level-1 region into a plurality of level-2 regions can include the steps below.

    [0019] Step 1021: Determine a reference location in the level-1 region.

    [0020] In this implementation, the sizes of actual geographic regions mapped from different latitudes are different, for example, the size of an actual region that is mapped from changing latitude by one degree in a high-latitude region is smaller than the size in a low-latitude region. Therefore, in this step, the reference location can be determined based on a latitude of the level-1 region that the service request belongs to.

    [0021] In one example, when the level-1 region is located in the north hemisphere, a higher-latitude location in the level-1 region can be determined as the reference location, for example, a northeast corner or a northwest corner of the level-1 region can be determined as the reference location. In another example, when the level-1 region is located in the south hemisphere, a higher-latitude location in the level-1 region can also be determined as the reference location, for example, a southeast corner or a southwest corner of the level-1 region can be determined as the reference location.

    [0022] Step 1022: Reach an offset location by performing shifting in a predetermined direction by the predetermined granularity based on the reference location, and obtain offset coordinate information of the offset location.

    [0023] In this implementation, shifting can be performed in a low-latitude direction based on the reference location. For example, referring to FIG 4, when the reference location is the northeast corner of the level-1 region, shifting can be separately performed westwards and southwards by the granularity based on the northeast corner, and a location reached after the shifting is referred to as the offset location. Similarly, when the reference location is the northwest corner of the level-1 region, shifting can be separately performed eastwards and southwards by the granularity based on the northwest corner, to reach the offset location. When the reference location is the southeast corner of the level-1 region, shifting can be separately performed westwards and northwards by the granularity based on the southeast corner, to reach the offset location. When the reference location is the southwest corner of the level-1 region, shifting can be separately performed eastwards and northwards by the granularity based on the southwest corner, to reach the offset location.

    [0024] In this step, after the offset location is reached, coordinate information of the offset location can be obtained. For ease of distinguishing, the coordinate information of the offset location can be referred to as offset coordinate information. Usually, the offset coordinate information can also be represented in a form of latitude and longitude coordinates.

    [0025] Step 1023: Calculate a change value between reference coordinate information of the reference location and the offset coordinate information.

    [0026] Based on step 1022, after the offset coordinate information of the offset location is obtained, the change value between the reference coordinate information and the offset coordinate information can be calculated. For example, a difference between latitude and longitude coordinate values of the reference location and latitude and longitude coordinate values of the offset location is calculated.

    [0027] Step 1024: Determine a size of the level-2 region based on the change value.

    [0028] In this implementation, assuming that the longitude difference between the reference location and the offset location is x, and the latitude difference between the reference location and the offset location is y, x and y can be determined as a length and a width of the level-2 region.

    [0029] Step 1025: Divide, based on the size of the level-2 region, the level-1 region that the service request belongs to into a plurality of level-2 regions.

    [0030] Based on step 1024, after the size of the level-2 region is determined, the level-1 region that the service request belongs to can be divided into a plurality of level-2 regions based on the determined size. For example, the level-1 region can be divided into a plurality of level-2 regions along a boundary of the level-1 region starting from the northeast corner of the level-1 region.

    [0031] It should be noted that, when division is performed to obtain the level-2 region, division can be performed starting from any corner of the level-1 region, for example, the southeast corner, the northwest corner, or the southwest corner. No limitation is imposed in the present disclosure. In addition, when the level-1 region is divided into a plurality of level-2 regions, the plurality of level-2 regions obtained through division can cover the level-1 region, that is, the sum of each size of the level-2 region obtained through division is usually greater than or equal to the size of the level-1 region. When the sum of each size of the level-2 region obtained through division is equal to the size of the level-1 region, it indicates that the level-1 region is divided into a plurality of level-2 regions of the same size.

    [0032] Step 103: Determine, based on the requesting location, a level-2 region that the service request belongs to.

    [0033] Based on step 102, after the level-1 region that the service request belongs to is divided into a plurality of level-2 regions, the level-2 region that the service request belongs to can be determined based on the requesting location.

    [0034] Step 104: Respond to the service request based on location information of all service objects in the level-2 region that the service request belongs to and an adjacent level-2 region.

    [0035] Based on step 103, after the level-2 region that the service request belongs to is determined, referring to FIG. 5, the service request can be responded to based on the steps below.

    [0036] Step 1041: Obtain the location information of all the service objects in the level-2 region that the service request belongs to and the adjacent level-2 region.

    [0037] In this implementation, after the level-2 region that the service request belongs to is determined, eight level-2 regions adjacent to the level-2 region can be determined. Referring to FIG 6, assuming that a rectangular region located in the center is the level-2 region that the service request belongs to, eight level-2 regions that are numbered from 1 to 8 around the level-2 region are level-2 regions adjacent to the level-2 region. In this step, location information of all service objects in the level-2 region that the service request belongs to and the eight level-2 regions adjacent to the level-2 region can be obtained.

    [0038] For example, assuming that the service request is a service request for searching for a restaurant near the current location, location information of all restaurants in the level-2 region that the service request belongs to and the eight level-2 regions adjacent to the level-2 region can be obtained.

    [0039] Step 1042: Calculate a distance between each service object and the requesting location based on the location information of the service object.

    [0040] Based on step 1041, after the location information of each service object is obtained, the distance between the service object and the requesting location can be calculated based on the location information. The service request for searching for a restaurant near the current location is still used as an example. A distance between each restaurant and the requesting location can be calculated based on the obtained location information of the restaurants.

    [0041] Step 1043: Push a service object with a distance satisfying a predetermined condition as a response to the service request.

    [0042] Based on step 1042, after the distance between each service object and the requesting location is calculated, the service object with a distance satisfying the predetermined condition can be pushed to the user initiating the service request as the response to the service request.

    [0043] In this implementation, the predetermined condition is usually a distance condition, which can be set by the developer, or can be customized by the user initiating the service request. Assuming that the service request is a request for searching for a nearby restaurant, the user can customize a distance of searching for the restaurant, for example, 200 meters or 500 meters, and the predetermined condition is as follows: the distance is less than 200 meters or 500 meters. If the user does not customize the distance, a default distance set by the developer can be used, for example, 300 meters.

    [0044] It can be learned from the previous descriptions that, during implementation of a location-based service in the present disclosure, the level-1 region that the service request belongs to can be determined based on the requesting location; the level-1 region is divided into a plurality of level-2 regions based on the predetermined granularity; and the service request is responded to based on the location information of all the service objects in the level-2 region that the service request belongs to and the adjacent level-2 region. Because all level-2 regions are of the same size, processing a service in a low-latitude region can save processing resources of a server, and improve performance of the server.

    [0045] Corresponding to the previous implementation of the location-based service implementing method, the present disclosure further provides an implementation of a location-based service implementing apparatus.

    [0046] The implementation of the location-based service implementing apparatus in the present disclosure can be applied to a server. The apparatus implementation can be implemented by software, hardware, or a combination of hardware and software. Software implementation is used as an example. As a logical apparatus, the software is formed by reading a corresponding computer program instruction in a non-volatile memory and running the instruction in a memory by a processor in a server of the apparatus. In terms of hardware, referring to FIG. 7, FIG 7 is a hardware structural diagram illustrating a server of a location-based service implementing apparatus in the present disclosure.
