Information pushing method, device and system

Technical Field

The present application relates to the field of communications, and in particular, to an information push method, apparatus, and system.

Background

The intelligent networked automobile is a new generation automobile which is provided with advanced vehicle-mounted sensors, controllers, actuators and the like, integrates modern communication and network technologies, realizes intelligent information exchange and sharing between the automobile and X (people, automobiles, roads, backstage and the like), has the functions of complex environment perception, intelligent decision, cooperative control, execution and the like, can realize safe, comfortable, energy-saving and efficient driving, and can finally replace people to operate. The Road infrastructure serves as a driving environment of the intelligent networked automobile, various traffic information (such as information of signal lamps, speed limit signs, roadside cameras and the like) is collected by means of Road Side Units (RSUs) and serves as infrastructure information, the infrastructure information is communicated with the automobile, reliable information service is provided for the automobile, and the intelligent networked automobile is an important application of the intelligent networked automobile.

In the existing infrastructure message pushing system, a road side subsystem collects data of infrastructure, integrates and packages the data, and broadcasts the data periodically through a special short-range wireless communication technology. After the vehicle-mounted subsystem enters the special short-range wireless communication coverage range of the road side subsystem, the data of the infrastructure information can be received, and the application of automatic driving and auxiliary driving of the intelligent internet automobile is supported. However, the scheme is limited in that vehicles are not generally equipped with vehicle-mounted intelligent terminals which completely rely on special short-range wireless communication at the present stage; in addition, the dedicated short-range wireless communication high-frequency broadcasting infrastructure information is utilized to occupy the originally scarce channel resources.

Based on the above, a new scheme is proposed in the industry, which comprises the steps of firstly collecting data of infrastructure, then uploading the collected data to a cloud server in real time, and storing the corresponding data in a database; the client sends a request to report the vehicle position in real time, and the cloud server generates service data and sends the service data to the client according to the request of the client based on the infrastructure data stored in the database; and the client receives the data and then displays the data to the user through the intelligent mobile terminal.

However, the vehicle-mounted client reports the position of the vehicle in real time, which causes large occupation of uplink bandwidth resources; all decisions are made in the cloud server, massive infrastructure information is processed, and processing pressure of the cloud server is increased.

Disclosure of Invention

The embodiment of the application provides an information pushing method, device and system, and the infrastructure information pushing method, device and system can be used for reducing uplink bandwidth and platform processing pressure.

In order to achieve the above purpose, the embodiment of the present application adopts the following technical solutions:

in a first aspect, an information pushing method is provided, and is applied to a server, and the method may include: the server receives a request message from the terminal device, the request message being used for requesting service area information, the service area information including an identifier of a service area, an identifier of a service provided in the service area, and geographical location information of the service area; the server sends the service area information requested by the terminal device to the terminal device; the server receives a subscription message from the terminal device, the subscription message including an Identification (ID) of a service area subscribed by the terminal device and an ID of a subscription service; the server pushes information of the subscribed services in the subscribed service area to the terminal device.

According to the information pushing method provided by the application, the terminal device requests the service area information firstly, then the subscribed service area and the subscribed service are selected in a decision mode, and the server pushes the information of the subscribed service in the subscribed service area according to the subscription request of the terminal device. Compared with the real-time reporting of self position to obtain service information, the method greatly reduces the uplink message volume and further reduces the uplink bandwidth because the terminal device requests the service area and then subscribes; the terminal device carries out partial decision, thereby reducing the decision quantity of the server and further reducing the processing pressure of the platform.

Wherein, the server can request the sending source of the service to obtain the latest information thereof, and then push the latest information to the terminal device. Alternatively, the server may acquire and store the latest information from the service source in real time or periodically, and push the latest information of the stored service source to the terminal device. This is not particularly limited in the present application.

With reference to the first aspect, in a possible implementation manner, the server pushes, to the terminal device, information of a service subscribed in a service area subscribed by the terminal device, which may specifically be implemented as: when receiving the subscription message, the server acquires the latest information of the subscribed service in the service area subscribed by the terminal device and pushes the latest information to the terminal device.

With reference to the first aspect or any one of the foregoing possible implementation manners, in another possible implementation manner, the terminal devices are included in a group, where the group includes terminal devices that subscribe to the same service in the same service area. Correspondingly, the server pushes the information of the subscribed service in the subscribed service area to the terminal device, which can be specifically implemented as follows: and when the information of the subscribed service in the subscribed service area changes, receiving the latest information of the subscribed service in the subscribed service area, and pushing the latest information to the terminal devices in the group. In the implementation mode, when the information of the subscribed service in the subscribed service area changes, the latest information is timely pushed to each terminal device subscribing the subscribed service in the subscribed service area, and the pushing is not based on the request of the terminal device any more, so that the pushing efficiency is improved, the interaction frequency is reduced, and the communication resource is saved.

Optionally, the change of the information of the service means that the information of the transmission source changes. The transmission source refers to a device that collects information and provides the collected information to a server. For example, in the basic information pushing scenario, the sending source may be an acquisition device of the infrastructure, such as a signal lamp, a camera, and the like. The present application is not limited to a specific type of transmission source. The sending source may communicate directly with the server to provide its information to the server; alternatively, the transmission source may be managed by a unified information management platform, and the platform communicates with the server to provide the server with information of the transmission source managed by the platform; or, the sending source can be directly communicated with the server by the convergence device after the information is converged by the convergence device; or, after the information is converged by the convergence device, the transmission source is communicated with the server through the information management platform by the convergence device; this is not particularly limited in the present application. Therefore, the server may receive information directly from the sender, may receive information from the information management platform, or may receive information from the aggregation device, and may collectively receive information from the sender.

For example, the information management platform may be a traffic management platform or the like, which is not specifically limited in this application. The aggregation device may be an RSU, etc., and this is not particularly limited in this application.

If the service area information set already comprises service area information corresponding to the first service, and an intersection exists between an area corresponding to the position information included in the newly received identification information of the first service and a service area corresponding to the first service in the service area information set, the position information of the area corresponding to the first service in the service area information set is modified according to the position information in the newly received identification information of the first service. And if the service area information set comprises service area information corresponding to the second service and the service area corresponding to the first service is completely overlapped with the service area corresponding to the second service, adding the identifier of the first service into the service area information corresponding to the second service.

As shown in fig. 5, an information pushing method provided in an embodiment of the present application may include:

s501, the terminal device transmits a request message to the server.

Wherein the request message is used for requesting service area information. Specifically, the service area information includes an identifier of the service area, an identifier of a service provided in the service area, and location information of the service area.

Optionally, a flag bit may be set in the request message to indicate that the message is a request message.

Alternatively, the request message may be null, and is used to request all service area information in the service area information set stored in the server.

Optionally, the request message may include: the geographical location information of the area requested by the terminal device, or the identifier of the service requested by the terminal device, or the geographical location information of the area requested by the terminal device and the identifier of the service requested by the terminal device, or the navigation path information, or the location information of the terminal device.

The location information of the area requested by the terminal device may be a geographic location or an administrative area location, which is not specifically limited in this embodiment of the present application.

The location information of the terminal device may be GPS coordinate information, or may be an identifier of a service area to which the terminal device belongs, and the present application does not specifically limit the location information of the terminal device.

Alternatively, the terminal apparatus may perform S501 when coming online. Alternatively, the terminal device may be triggered by the upper application to execute S501 when the client using the terminal device uses an application in the terminal device. In the embodiment of the present application, the timing of executing S501 is not particularly limited. It should be further noted that, for the specific content of the request message, the configuration may be configured according to actual requirements, which is not specifically limited in the embodiment of the present application, and all the processes of requesting the service area information through the request message belong to the specific implementation of S501.

Further, the service area information requested by the terminal device is at least one item of service area information in the service area information set stored in the server. The service area information set is a database which is set by the server according to the information of the sending source and comprises at least one item of service area information.

Illustratively, as shown in tables 1 and 2, two service area information sets are illustrated. It should be noted that, in practical applications, the form of the service area information set may be a form other than a table, and the content of the service area information set may also be configured according to actual requirements, and tables 1 and 2 are only exemplary and are not specific limitations thereof. Further, the service area information set may also include contents other than those illustrated in table 1 and table 2.

TABLE 1

Service area identification	Service identification	Location information of service area
			Region identifier 1	Service identification 1	P1……Pn
Region identification 2	Service identification 1	Pa……Pj
			Region identification 2	Service identification 2	Pa……Pj
Region identification 3	Service identification 2	Po……Pz
			……	……	……

TABLE 2

It should be noted that if more than two services are provided in one service area, more than two items of service area information of the service area may be set in the service area information set, and the service identifier in each item of service area information includes 1 service identifier, for example, the service area information where the area identifier 2 indicated in table 1 is located. If more than two services are provided in a service area, one service area information of the service area may be set in a service area information set, and the service identifier in the service area information includes a plurality of service identifiers, for example, information where the area identifier 2 indicated in table 2 is located.

S502, the server receives a request message from the terminal device.

It should be noted that the request message received by the server in S502, that is, the request message sent by the terminal device in S501, has already been described in detail in S501, and is not described again here.

S503, the server transmits the service area information requested by the terminal device to the terminal device.

Specifically, when S503 is executed, the server transmits the service area information requested by the terminal device to the terminal device according to the content of the request message.

In one possible implementation, the request message is empty, and the service area information requested by the terminal device includes: all the service area information in the service area information set.

In another possible implementation, the request message includes: geographical location information of an area requested by the terminal device; in this case, the service area information requested by the terminal device includes: and service area information of at least one service area spanning the area requested by the terminal device in the service area information set.

The at least one service area spanned by the area requested by the terminal device refers to at least one service area in which the area requested by the terminal device falls.

In another possible implementation, the request message includes: an identifier of a service requested by the terminal device; the service area information requested by the terminal device includes: the service area information set includes service area information of at least one service area for providing a service requested by the terminal device.

In another possible implementation, the request message includes: geographical location information of an area requested by the terminal device and an identifier of a service requested by the terminal device; the service area information requested by the terminal device includes: and service area information of at least one service area, which is spanned by the area requested by the terminal device and provides the service requested by the terminal device, in the service area information set.

In another possible implementation, the request message includes: navigation path information; the service area information requested by the terminal device includes: and in the service area information set, the service area information of at least one service area crossed by the path indicated by the navigation path information.

In another possible implementation, the request message includes: location information of the terminal device; the service area information requested by the terminal device includes: and in the service area information set, the service area information of at least one service area in the preset range of the position indicated by the position information of the terminal device.

S504, the terminal device receives the requested service area information from the server.

It should be noted that the service area information requested by the terminal device received by the terminal device in S504, that is, the service area information requested by the terminal device sent by the server in S503, has already been described in detail in S503, and is not described again here.

And S505, the terminal device determines the subscribed service area and the subscribed service according to the service area information and the service requirement requested by the terminal device.

The terminal device subscribes to the service at the final purpose, and the terminal device selects the service subscribed at the final purpose and expects to acquire the information of the transmission source of the service. Thus, the subscription service may be equivalent to the subscription sending source. In practical applications, the "subscription service" described herein can be replaced by the "subscription sending source" application, and the effect of the scheme is unchanged.

Specifically, the specific process of S505 may be configured according to actual requirements, which is exemplified as follows in the present application, but is not limited to the specific implementation of S505.

Optionally, in a possible implementation manner, the location division (embodied by the area coordinates) of the service area, the identifier of the service, and other information are known by the terminal device and the server, and when S505 is executed, the terminal device may determine the content of interest to be selected according to the service requirement, the location of the terminal device, and the known information.

For example, in an infrastructure push scenario, a vehicle determines a subscribed service area and a subscribed service in combination with its own location information and service requirements. For example, when a vehicle enters an area covered by a signal lamp and needs to acquire the information of a transmission source (signal lamp) of the area, the vehicle subscribes to a service area spanned by the area and subscribes to the signal lamp service, so that the vehicle subscribes to the signal lamp service in the service area spanned by the area to acquire the information of the signal lamp service in the service area spanned by the area. For another example, if the vehicle realizes a green wave band scene and needs to pay attention to the signal light information of 2-3 intersections in the future, the service areas to which the geographic areas of 2-3 intersections in the future at the current position belong and the signal light service are subscribed.

It should be noted that, in different scenarios, the process of executing S505 by the terminal device may be determined according to actual requirements, and details are not described here any more.

S506, the terminal device transmits a subscription message to the server.

The subscription message includes an ID of a service area subscribed by the terminal device and an ID of a subscription service.

Specifically, the ID of the service area is information uniquely indicating the service area, and the ID of the service is information uniquely indicating the service. The ID may be a binary string, or other binary strings, or letters, etc., and any information that can be used to uniquely distinguish content may be used as the ID, which is not specifically limited in this embodiment of the application.

Optionally, the subscription message may further include a subscription identifier for indicating the role of the subscription message, and the subscription identifier is known by the terminal device and the server. The form and content of the subscription identifier may be configured according to actual requirements, which is not specifically limited in the embodiment of the present application.

S507, the server receives the subscription message from the terminal device.

In S507, the subscription message received by the server from the terminal device, that is, the subscription message sent by the terminal device in S506, is already described in S506 in detail, and is not repeated here.

S508, the server pushes the information of the subscribed services in the subscribed service area to the terminal device.

Alternatively, in S508, the server pushes the terminal device with the information of the subscribed services in the service area to which the server subscribes, which may include, but is not limited to, case 1 and case 2 described below.

Case 1, S508 is embodied as: when receiving a subscription message sent by a terminal device, a server acquires the latest information of a subscription service in a service area subscribed by the terminal device and pushes the latest information to the terminal device.

The latest information is information with reference to time, that is, the latest information of the current time. It is to be understood that the latest information described herein is the latest information when this step is performed.

Specifically, in S508, the server determines, according to the subscription message, a transmission source of the subscription service in the service area subscribed by the terminal device, and then obtains current latest information of the transmission source, which is pushed to the terminal device as information of the subscription service in the service area subscribed by the terminal device.

Optionally, when executing S508, the server may request, in a manner of requesting a response, a sending source, an information management platform, or an aggregation device, to acquire information of a service subscribed in a service area subscribed by the terminal device.

Optionally, the server may receive and store information of each transmission source reported by the transmission source or the information management platform in real time or periodically, and query the information of the service subscribed in the terminal device area stored in the server when executing S508.

Optionally, how the service area and the service correspond to the sending source may be embodied in a form of a preset corresponding relationship, and when S508 is executed, the preset corresponding relationship is queried through the identifier of the service area subscribed by the terminal device and the identifier of the subscribed service, that is, the sending source of the subscribed service in the service area subscribed by the terminal device may be obtained, and then information of the sending source is obtained. The preset correspondence includes an identifier of at least one service area, an identifier of a service provided in the service area, and an identifier of a transmission source of the service.

Exemplarily, as shown in table 3 and table 4, two preset correspondences are illustrated. It should be noted that, in practical application, the form of the preset correspondence may be a form other than a table, and the content of the preset correspondence may also be configured according to actual requirements, and tables 3 and 4 are only exemplary illustrations and are not specifically limited thereto. Further, the preset correspondence may also include contents other than those shown in tables 3 and 4.

TABLE 3

Service area identification	Service identification	Transmission source identification
			Region identifier 1	Service identification 1	Signal lamp 1
Region identification 2	Service identification 1	Signal lamp 2
			Region identification 3	Service identification 2	Vehicle speed detector 1
Region identification 4	Service identification 1	Signal lamp 3
			Region identification 4	Service identification 2	Vehicle speed detector 1
Region identification 5	Service identification 1	Signal lamp 1
			Region identifier 6	Service identification 2	Vehicle speed detector 2
……	……	……

TABLE 4

It should be noted that if more than two services are provided in one service area, more than two items of information in the service area may be configured in a preset corresponding relationship, and the service identifier in each item of information includes 1 service identifier, for example, the information where the area identifier 4 indicated in table 3 is located. If more than two services are provided in a service area, one item of information of the service area may be configured in a preset corresponding relationship, where the service identifier in the information includes a plurality of service identifiers, for example, information where the area identifier 4 indicated in table 4 is located.

For example, if the terminal device desires to subscribe to the information of the signal lamp service in the service area indicated by the area identifier 5 during execution of S505, the terminal device subscribes to the service area indicated by the area identifier 5 and subscribes to the signal lamp service, and the subscription message in S506 includes the area identifier 5 and the service identifier 1. In S508, based on the preset correspondence shown in table 3, the server determines that the subscription transmission source of the terminal device is the signal lamp 1 according to the area identifier 5 and the service identifier 1, that is, obtains information of the signal lamp 1 and pushes the information to the terminal device.

It should be noted that the service area information set described in S501 may be combined with the preset corresponding relationship described in S508, or may be separately set, which is not specifically limited in this embodiment of the present application. When the service area information set described in S501 can be combined with the preset correspondence described in S508, the service area information set is embodied by a large database, the preset correspondence described in S508 is partial information in the database, and the service area information set described in S501 is partial information in the database. Of course, this database may also be referred to as a preset correspondence described in S508, or a service area information set described in S501.

Case 2, the terminal device sending the subscription request is included in a group, and the group includes terminal devices subscribing to the same service in the same service area; when the information of the subscribed service in the service area subscribed by the terminal device changes, the server may receive the latest information of the subscribed service in the subscribed service area, and at this time, S508 is specifically implemented as: the server pushes the latest information to the terminal devices in the group.

Optionally, in case 2, the server pushes the latest information to the terminal devices in the group, and may push the latest information separately in a unicast manner, or may broadcast the latest information in an eMBMS manner. This is not particularly limited in the embodiments of the present application.

Specifically, in case 2, when the information of the transmission source changes, the server pushes the changed latest information to the terminal apparatus subscribed to the information of the transmission source in real time.

Further optionally, corresponding to the case 2, the information pushing method provided in the embodiment of the present application may further include, after receiving the subscription message, adding an identifier of the terminal device that sends the subscription message to a group of a transmission source of the subscription service in the service area subscribed by the terminal device.

In one possible implementation, a group may be established for each transmission source, and the group stores the identifier of the terminal device subscribed to the transmission source service, so as to push the latest information to each terminal device in the group when the transmission source information changes. And if the information of the first sending source changes, the server pushes the latest information of the first sending source to each terminal device in the group of the first sending source. The first transmission source may be a transmission source of any service provided by a service area managed by the server.

It is understood that the server also stores groups of each transmission source, and a group of a transmission source includes an identifier of a terminal device that acquired the transmission source information, and is used for pushing the latest information of the transmission source to each terminal device in the group in time when the transmission source information changes.

Optionally, the group of the transmission sources stored in the server may be merged with and deployed in the service area information set described in S501 and the preset corresponding relationship described in S508, or may be stored separately, which is not specifically limited in this embodiment of the present application.

In this way, the terminal device can receive the latest message of the changed transmission source pushed by the server as long as the information of the transmission source changes after acquiring the latest information of the transmission source by transmitting the subscription message.

S509, the terminal device receives the information of the subscribed service in the subscribed service area pushed by the server.

It should be noted that, the information of the subscribed service in the service area received by the terminal device in S509, that is, the content pushed by the server in S508, is not described herein again.

According to the information pushing method provided by the application, the terminal device requests the service area information firstly, then the subscribed service area and the service are selected in a decision-making mode, and the server pushes the information of the subscribed service in the subscribed service area according to the subscription request of the terminal device. Compared with the real-time reporting of self position to obtain service information, the method greatly reduces the uplink message volume and further reduces the uplink bandwidth because the terminal device requests the service area and then subscribes; the terminal device carries out partial decision, thereby reducing the decision quantity of the server and further reducing the processing pressure of the platform.

Optionally, the server pushes, to a terminal device subscribing to a service in a service area subscribed to by the terminal device, the latest information sent by the sending source when the information changes, and may send the latest information to each terminal device separately in a unicast manner or broadcast in an eMBMS manner. This is not particularly limited in the embodiments of the present application.

Furthermore, when the terminal device cancels the subscription, the subscription can be cancelled in time, and the accuracy of sending source information pushing is ensured. As shown in fig. 6, the information pushing method provided by the present application may further include S510 and S511.

S510, the terminal device sends a unsubscribe message to the server.

The unsubscribe message comprises an identifier of a service area which the terminal device requests to cancel attention and an identifier of a service which the terminal device cancels subscription.

Optionally, the unsubscribe message may further include a unsubscribe identifier for indicating the role of the unsubscribe message, and the unsubscribe identifier is known by the terminal device and the server. The form and content of the unsubscribe identifier may be configured according to actual requirements, which is not specifically limited in the embodiment of the present application.

S511, the server receives the unsubscribe message from the terminal device.

After S511, when the server receives a certain transmission source and when the information of the transmission source changes, the terminal apparatus that has already unsubscribed from the transmission source information does not need to push the latest information at that time.

Further, corresponding to case 2 in S508, after S511, the server deletes the identification of the terminal device that transmitted the unsubscribe message from the group of the transmission source of the unsubscribed service from the unsubscribed service area.

Further, as described in S501 and S508, the server obtains information to set the preset corresponding relationship and the service area information set, and the information pushing method provided by the present application may further include a setting process of the server. Fig. 7 illustrates a process of setting a service area information set by a server, and setting the preset corresponding relationship is similar to the process and is not described in detail again. It should be noted that the process of setting the service area information set by the server illustrated in fig. 7 may be performed before or after any step of the information pushing method illustrated in fig. 5 or fig. 6, and the execution timing of the process of setting the service area information set by the server in the embodiment of the present application is not specifically limited.

As shown in fig. 7, the process of setting the service area information set by the server may specifically include:

s701, the server receives the identification information of the first service.

The identification information of the first service comprises an identification of the first service and position information of an area corresponding to the first service; the first service is any service provided by a service area managed by the server.

S702, the server sets a service area information set according to the identification information of the first service.

Specifically, when the server sets the service area information set according to the identification information of the service, the service area is divided first, and then the service area information set is set according to the content of the service area information set.

Optionally, an embodiment of the present application provides a principle of setting a service area information set, where the server sets the service area information set according to identification information of a first service, and specifically includes:

and if the service area information set already comprises the service area information corresponding to the first service, and the area corresponding to the position information included in the identification information of the newly received first service is completely overlapped with the service area corresponding to the first service in the service area information set, discarding the identification information of the newly received first service.

And if the service area information set already comprises the service area information corresponding to the first service, and the area corresponding to the position information included in the newly received identification information of the first service is intersected with the service area corresponding to the first service in the service area information set, modifying the position information of the area corresponding to the first service in the service area information set according to the position information in the newly received identification information of the first service.

And if the service area information set comprises service area information corresponding to the second service and the service area corresponding to the first service is completely overlapped with the service area corresponding to the second service, adding the identifier of the first service into the service area information corresponding to the second service.

If the service area information set comprises service area information corresponding to the second service, and the service area corresponding to the first service and the service area corresponding to the second service have intersection, setting the intersection area as a new service area and allocating an identifier, modifying position information of a non-intersection area belonging to the service area corresponding to the second service, and setting the non-intersection area belonging to the first service corresponding area as a new service area and allocating an identifier.

And if the service area information set comprises service area information corresponding to the second service and the service area corresponding to the first service is not intersected with the service area corresponding to the second service, setting a new service area for the first service corresponding area and allocating an identifier.

In a possible implementation, the principle of setting the service area information set is decomposed into steps, and a process of setting the service area information set is provided as shown in fig. 8. Of course, the principle of setting the service area information set may be decomposed into steps and configured according to actual requirements, which is not specifically limited in the embodiment of the present application.

Referring to fig. 8, a method for setting a service area information set according to an embodiment of the present application may include:

s801, the server receives the identification information of the first service.

The identification information of the first service comprises an identification of the first service and geographical location information corresponding to the first service.

S802, the server judges whether the received identification information of the first service is intersected with the geographical position of any service area in the service area information set stored in the server.

In S802, if the determination result is yes, S803 is executed; if not, go to step S808.

S803, the server judges whether the received identification information of the first service is completely overlapped with the geographic position of any service area in the service area information set stored in the server.

In S803, if the determination result is yes, S804 is executed; if not, go to step S806.

S804, the server judges whether the identification information of the first service is the same as the service identification in the service area information of the service area with the completely coincident geographical position in the service area information set stored in the server.

In S804, if the determination result is yes, the process is ended, which indicates that the content embodied by the received identifier information of the first service already exists in the service area information set; if not, go to step S805.

S805, the server adds the identifier of the first service to the service area information that is the same as the area of the first service.

S806, the server judges whether the identification information of the first service is the same as the service identification in the service area information of the service area with intersection with the geographical position in the service area information set stored in the server.

In S806, if yes, go to S807; if not, go to step S809.

S807, the server updates the geographical range of the service area which is the same as the geographical area in the identification information of the first service in the service area information set stored in the server.

In S807, the geographic range of the service area in the service area information set stored in the server, which is the same as the geographic range in the identification information of the first service, is updated to the geographic range carried in the identification information of the first service.

S808, the server adds a service area identifier of the first service in the service area information set, the service identifier in the corresponding service area information is the identifier of the first service, and the position information is the position information carried in the identifier information of the first service.

S809, the server takes the intersection part to establish a new service area, a first service identification is added in the service identification, the geographic coordinates of the original service area of the non-intersection part are updated, the first service part is added, and new service area information is established.

Further, the server maintains a service area information set according to the information, including the setting of the service area information and the deletion of the service area information. The operation principle of deleting the service area information is as follows: comparing the service area to which the area to be deleted belongs with the service area identifier in the service area information set, and if the service area to which the area to be deleted belongs does not have an intersection, or if the service area to which the area to be deleted belongs does not have the same service but the intersection, not deleting the area to be deleted; if the two have intersection and only have one kind of the same business, delete the intersection part in the geographic coordinate of the business area with intersection of the area to be deleted in the information set of the business area, narrow the business area; if the two are intersected and completely overlapped, and a plurality of services exist in the service region intersected with the region to be deleted in the service region information set, deleting the services to be deleted in the service region information intersected with the region to be deleted in the service region information set; if the two have intersection and there are multiple services in the service area with intersection with the area to be deleted in the service area information set, the service area is distinguished according to the service to be deleted and the service not to be deleted, the service area not to be deleted is unchanged, the service identification is updated as new service area information, the service area of the service to be deleted is newly added, and the intersection part is deleted in the geographic coordinates. As shown in fig. 9, the process of disassembling the deleted service area information may include:

s901, the server receives the deletion information.

The deleting information comprises the geographical position information of the area to be deleted and the service identifier to be deleted.

S902, the server judges whether the area to be deleted intersects with the geographical position of any service area in the service area information set stored in the server according to the geographical position information of the area to be deleted.

In S902, if the determination result is yes, S903 is executed; if not, the deleting process is ended.

S903, the server judges whether the service to be deleted is provided in the service area where the service area information set and the geographical position of the area to be deleted have intersection.

In S903, if the determination result is yes, S904 is executed; if not, the deleting process is ended.

S904, the server judges whether other services except the service to be deleted are provided in the service area where the service area information set and the geographical position of the area to be deleted have intersection.

In S904, if the determination result is yes, S906 is performed; if not, the deletion process is ended after S905 is executed.

S905, the server deletes the intersection part in the geographic coordinates of the service area which has intersection with the area to be deleted in the service area information set.

S906, the server judges whether the service area with the intersection between the service area information set and the geographic position of the area to be deleted completely coincides with the area to be deleted.

In S906, if the determination result is yes, the deletion process is terminated after S907 is executed; if not, go to S908.

S907, the server deletes the service to be deleted from the service area information of the service area with intersection between the service area information set and the geographical position of the area to be deleted.

S908, the server reserves other services except the service to be deleted in the service area information of the service area with intersection between the service area information set and the geographical position of the area to be deleted, and updates the service identification; and deleting the intersection part from the geographical coordinates of the service area information of the service area with the intersection between the service area information set and the geographical position of the area to be deleted as new service area information.

The above-mentioned scheme provided by the embodiment of the present application is introduced mainly from the perspective of the working process of the server and the terminal device. It is to be understood that the server and the terminal apparatus include hardware structures and/or software modules for performing the respective functions in order to realize the functions. Those of skill in the art would readily appreciate that the various illustrative elements and algorithm steps described in connection with the embodiments disclosed herein may be implemented as hardware or combinations of hardware and computer software.
