Fig. 1 is a schematic diagram illustrating an application scenario of a positioning information service system 100 according to some embodiments of the present application. For example, the location information service system 100 may be an online service platform for a variety of services. In some embodiments, the location information service system 100 may be used for real-time updating and displaying of location information in a network appointment service, for example, real-time updating and displaying of location information of taxis, real-time updating and displaying of location information of express buses, real-time updating and displaying of location information of special buses, real-time updating and displaying of location information of passengers, and the like. In some embodiments, the location information service system 100 may also be used for home services, courier, take-out, and the like. For example, in a courier order, the location information of the current delivery person is displayed. The location information services system 100 may include a server 110, a network 120, one or more service requester terminals 130, one or more service provider terminals 140, a storage device 150, an information source 160, and a navigation system 170. The server 110 may include a processing engine 112.

In some embodiments, the server 110 may be a single server or a group of servers. The server farm can be centralized or distributed (e.g., server 110 can be a distributed system). In some embodiments, the server 110 may be local or remote. For example, the server 110 may access information and/or data stored in the storage device 150, the service requester terminal 130, the service provider terminal 140 through the network 120. As another example, the server 110 may be directly connected to the storage device 150, the service requester terminal 130, the service provider terminal 140 to access stored information and/or data. In some embodiments, the server 110 may be implemented on a cloud platform. By way of example only, the cloud platform may include a private cloud, a public cloud, a hybrid cloud, a community cloud, a distributed cloud, between clouds, multiple clouds, the like, or any combination of the above. In some embodiments, server 110 may be implemented on a computing device similar to that shown in FIG. 2 or FIG. 3 of the present application. For example, server 110 may be implemented on one computing device 200 as shown in FIG. 2, including one or more components in computing device 200. As another example, server 110 may be implemented on a mobile device 300 as shown in FIG. 3, including one or more components in computing device 300. In some embodiments, processing engine 112 may process data and/or information related to location information services to perform one or more of the functions described herein.

FIG. 4 is a block diagram of a real-time updated positioning system according to some embodiments of the present application. As shown in fig. 4, the real-time updated positioning system may include an acquisition module 410, a first communication module 420, a second communication module 430, a first detection module 440, and a first frequency adjustment module 450. In some embodiments, the obtaining module 410, the first communication module 420, the second communication module 430, the first detecting module 440, and the first frequency adjusting module 450 may be included in the server 110 shown in fig. 1.

The acquisition module 410 may be used to acquire positioning information of an object at different times. In some embodiments, the target may refer to the service provider terminal 140. For example, in a network appointment service, the target may be a driver and the client may be a passenger. The passenger needs to know whether the driver has reached the specified starting position, where the driver's current position is. In some embodiments, the location information of the target may be acquired by the navigation system 170 in the location information service system 100. For example, the target may communicate with the navigation system via its own positioning device to obtain its own positioning information. In some embodiments, the target may actively send the positioning information of different times to the server, and the server may update the positioning information of the target in real time when receiving the positioning information of the target. In some embodiments, the positioning information may include position information of the target and timing information corresponding to the position information. In some embodiments, the location information may be latitude and longitude coordinates of the target, a geocode representing the location, or the like. In some embodiments, each location information has timing information corresponding thereto. For example, the corresponding time of the position information, or a group of position information is sorted in chronological order. In some embodiments, the latest positioning information may be obtained according to the timing information, and the positioning information may be updated. In some embodiments, the different time instants may refer to updating the positioning information at certain time intervals. For example, the positioning information of the target may be acquired every 0.05 seconds.

The first communication module 420 may be configured to transmit the positioning information to the client at a first frequency based on the first communication mode. In some embodiments, the first communication mode may be a push mode. Namely, the server can actively send the positioning information of the target to the client without the inquiry of the client. In some embodiments, location information for the target may be sent to the client at the first frequency. For example, the location information is sent to the client every 0.5 seconds. In some embodiments, the first frequency is variable. For example, the first frequency may be adjusted, increased or decreased under different circumstances or according to different requests of the client.

The second communication module 430 may be configured to obtain, based on the second communication mode, a location information query request sent by the client at the second frequency; and the server is used for responding to the positioning information inquiry request based on the second communication mode and sending the positioning information to the client. In some embodiments, the second communication mode may be a polling mode. Namely, the positioning information of the target is sent to the client according to the inquiry of the client. In some embodiments, the client sends an inquiry request for location information to the server at a second frequency. In some embodiments, the second frequency may be the same as the first frequency or may be different from the first frequency. For example, the first frequency may be greater than the second frequency, that is, the client updates the positioning information more frequently through the first communication mode, and updates the positioning information less frequently through the second communication mode. This helps to maintain both modes of communication while avoiding taking up too much network resources and burdening the server. Or the second frequency is greater than the first frequency, and the client updates the positioning information more frequently through the second communication mode. In some embodiments, the first communication mode and the second communication mode may be independent. The server can send the positioning information of the target to the client at a first frequency through the first communication mode, meanwhile, the server obtains inquiry information sent by the client through the second communication mode, and the positioning information of the target is sent to the client. In some embodiments, the first communication mode and the second communication mode may be based on the first communication mode, and assisted by the second communication mode, to send the target location information to the client. In some embodiments, the second communication mode may be the primary mode, and the first communication mode may be the secondary mode.

The first detection module 440 may be configured to detect a first time interval during which a location information query request is obtained. In some embodiments, the first time interval may be a time interval between two adjacent positioning information inquiry requests sent by the client. In some embodiments, the first time interval and the second frequency should ideally coincide. For example, if the second frequency is to send location information query requests every 0.5 seconds, the server would ideally receive one query request every 0.5 seconds. However, in practical situations, the data transmission process is complicated, and different time deviations occur when receiving or sending data, so that the server cannot always stably and timely receive the inquiry request. If the deviation between the first time interval and the second frequency is within the normal range, the second communication mode can be considered to work normally, and the positioning information client sent by the server can receive the positioning information. If the second communication mode has problems, the client cannot receive the positioning information for a long time or the server cannot receive the inquiry request of the client for a long time.

The first frequency adjustment module 450 may be configured to adjust the first frequency according to the first time interval. In some embodiments, the first frequency is increased when the first time interval is greater than a first threshold. In some embodiments, the first frequency is decreased when the first time interval is less than a second threshold. If the first time interval is greater than the first threshold, the second communication mode may not work normally, and at this time, the first frequency of the first communication mode may be increased to ensure the update frequency of the client location information. Similarly, if the second frequency of the client increases the second frequency of the second communication mode by adjustment, the first time interval is shortened, and when the first time interval is smaller than the second threshold, the first frequency of the first communication mode can be adjusted to reduce the first frequency, so that the client is ensured to update the target positioning information normally, and meanwhile, the server and the network are prevented from being burdened. In some embodiments, the first time interval is not greater than the first threshold and is not less than the second threshold, and the first frequency may be maintained unchanged. In some embodiments, the first frequency adjustment module 450 may adjust the first frequency based on an adjustment request from the client. For example, the client determines whether the first frequency needs to be adjusted according to the situation that the client receives the positioning information in the second communication mode, so as to ensure that the positioning information is updated normally.

In some embodiments, the first frequency adjustment module 450 may obtain a distance between the client and the target. In some embodiments, the distance between the client and the target is a route distance. In some embodiments, when the distance is less than or equal to a predetermined value, the first frequency is increased to increase the update frequency of the positioning information. For example, the predetermined value may be 100 meters, and in the online booking order, when the client (passenger) is within 100 meters of the target (driver), in order for the passenger to know the position of the driver in real time, the first frequency may be increased, so as to speed up the update frequency of the positioning information. In some embodiments, the first frequency may be kept unchanged when the distance is greater than a predetermined value.

In some embodiments, the first frequency adjustment module 450 may obtain a distance between the client and the target, and issue an instruction to increase the second frequency to the client when the distance is less than or equal to a predetermined value, so as to increase the update frequency of the positioning information. For example, the predetermined value may be 100 meters, and in the online booking order, when the client (passenger) is within 100 meters of the target (driver), the client (passenger) can know the position of the driver in real time, and the server sends an instruction for increasing the second frequency to the client. In some embodiments, when the distance is greater than the predetermined value, the instruction to adjust the second frequency may not be issued, and the instruction to keep the second frequency unchanged may also be issued to the client.

It should be understood that the system and its modules shown in FIG. 4 may be implemented in a variety of ways. For example, in some embodiments, the system and its modules may be implemented in hardware, software, or a combination of software and hardware. Wherein the hardware portion may be implemented using dedicated logic; the software portions may be stored in a memory for execution by a suitable instruction execution system, such as a microprocessor or specially designed hardware. Those skilled in the art will appreciate that the methods and systems described above may be implemented using computer executable instructions and/or embodied in processor control code, such code being provided, for example, on a carrier medium such as a diskette, CD-or DVD-ROM, a programmable memory such as read-only memory (firmware), or a data carrier such as an optical or electronic signal carrier. The system and its modules of the present application may be implemented not only by hardware circuits such as very large scale integrated circuits or gate arrays, semiconductors such as logic chips, transistors, or programmable hardware devices such as field programmable gate arrays, programmable logic devices, etc., but also by software executed by various types of processors, for example, or by a combination of the above hardware circuits and software (e.g., firmware).

It should be noted that the above descriptions of the candidate item display and determination system and the modules thereof are only for convenience of description, and are not intended to limit the present application within the scope of the illustrated embodiments. It will be appreciated by those skilled in the art that, given the teachings of the present system, any combination of modules or sub-system configurations may be used to connect to other modules without departing from such teachings. For example, in some embodiments, for example, the obtaining module 410, the first communication module 420, the second communication module 430, the first detecting module 440, and the first frequency adjusting module 450 disclosed in fig. 4 may be different modules in a system, or may be a module that implements the functions of two or more modules described above. For example, the first detecting module 440 and the first frequency adjusting module 450 may be two modules, or one module may have both detecting and adjusting functions. For example, each module may share one memory module, and each module may have its own memory module. Such variations are within the scope of the present application.

FIG. 5 is a block diagram of a real-time display positioning system according to some embodiments of the present application. As shown in fig. 5, the real-time updated positioning system may include a third communication module 510, a fourth communication module 520, a positioning information update module 530, a second detection module 540, and a second frequency adjustment module 550. In some embodiments, the third communication module 510, the fourth communication module 520, the positioning information update module 530, the second detection module 540, and the second frequency adjustment module 550 may be included in the service requester terminal 130 or the service provider terminal 140 shown in fig. 1.

The third communication module 510 may be configured to receive positioning information of a target transmitted by the server at the first frequency based on the first communication mode. In some embodiments, the first communication mode may be a PUSH mode, for example, the PUSH mode may be any one or combination of SMS-PUSH, WAP-PUSH, MMS-PUSH, HTTP server PUSH, persistent connection PUSH, Flash XMLSocket delivery, and the like. In some embodiments, a first communication channel between the server and the client may be established first based on the first communication mode, after which the server may send the location information of the target to the client at the first frequency without the client issuing an inquiry request. In some embodiments, the client may first send a subscription request to the server for subscribing to the target location information via the first communication mode. Based on the subscription request, a communication channel of a first communication mode is established between the server and the client, and the server actively sends the positioning information of the target to the client at a first frequency periodically after receiving the updated positioning information of the target. In some embodiments, when the communication access in the first communication mode needs to be closed and the positioning information is no longer received, the client needs to send a request for canceling the subscription to the server, and the server stops sending the positioning information to the client when receiving the request for canceling the subscription sent by the client.

The fourth communication module 520 may be configured to send a location information query request related to the target to the server at a second frequency based on the second communication mode; and means for receiving the location information of the target answered by the server based on the second communication mode. In some embodiments, the second communication mode may be a Polling mode, for example, the Polling mode may be any one or a combination of hub Polling (HubPolling), round-robin Polling (Roll call Polling), unicast Polling, multicast Polling, and long Polling (LongPolling). The client needs to send an inquiry request to the server when the client wants to acquire the positioning information of the target. When receiving a query request from the client, the server will respond to the query request and send the current positioning information to the client. If the client does not send an inquiry request, the server will not send the location information to the client. Therefore, when the client needs to know the real-time positioning information of the target, the client needs to continuously send an inquiry request to the server. In some embodiments, if the client wants to turn off the second communication mode, it only needs to stop sending the query request of the target location information.

The positioning information updating module 530 may be configured to update the positioning information of the target at the third frequency. In some embodiments, the positioning information includes position information of the target and timing information corresponding to the position information. In some embodiments, the timing information may be a specific time. For example, the timing information corresponding to the a-position information may be 21 minutes 15.0 seconds at 10 am on 8/2018, and the timing information corresponding to the B-position information may be 21 minutes 15.5 seconds at 10 am on 8/2018. Which positioning information is the latest can be distinguished from the timing information. In some embodiments, the timing information may be a sequence of the position information arranged in a front-to-back order. For example, the timing information corresponding to the a-position information is 1011, the timing information corresponding to the B-position information is 1012, the timing information may be a sequence of increasing numbers, and the positioning information is updated as the number value of the number is larger. In some embodiments, the timing information in the positioning information is represented in a consistent manner, that is, the positioning information received in the first communication mode and the second communication mode both include timing information with consistent representation. The client may rank the positioning information based on the timing information. And updating and displaying the positioning information based on the sorting. In some embodiments, the client receives the positioning information sent by the server, the positioning information may be stored in a memory (the memory 360, the storage unit 390, the rom 230 or the ram 240) of the client, and the positioning information updating module 530 obtains the latest positioning information in the memory, and updates the latest positioning information at the client according to a third frequency. In some embodiments, the target location information may be displayed in a text form, for example, directly displaying the location information of the target, or displaying the distance from the target to the client. In some embodiments, the display mode of the object positioning information may be an animation mode, for example, the object is displayed according to the corresponding position of the positioning information in the map, and the position of the object in the map is dynamically updated.

The second detection module 540 may be configured to detect a second time interval between sending the location information query request and receiving the location information in response to the server. Transmitting a first frequency adjustment request to the server based on the second time interval. In some embodiments, in the actual transmission process, if the second time interval is stable within a certain normal range, it may be considered that the second communication mode is working normally, the server may receive the query request sent by the client, and the client may receive the location information of the response sent by the server in time. In some embodiments, if the second time interval is beyond the normal range, it may be considered that the second communication mode is abnormal, and a first frequency adjustment request may be sent to the server to ensure that the client can update the positioning information normally. In some embodiments, the second detection module 540 may be configured to send a request to the server to increase the first frequency when the second time interval is greater than a third threshold. In some embodiments, if the second time interval is greater than the third threshold, the second communication mode may be considered to be abnormal, and the client may not receive the response positioning information sent by the server. In some embodiments, a request to increase the first frequency may be sent to the server to increase the first frequency of the first communication mode to ensure that the client is still able to receive the location information. In some embodiments, the third threshold may be greater than the second frequency. For example, when the second frequency is that the inquiry request is sent to the server every 0.5 seconds, if the second time interval exceeds 0.8 seconds, it can be considered that the second communication mode is abnormal, and there is a risk of interruption. The client may send a request to the server to increase the first frequency.

In some embodiments, the second detection module 540 may be configured to detect a third time interval of receiving the positioning information of the target sent by the server based on the first communication mode. In some embodiments, the first communication mode may be considered to be operating properly if the third time interval is stable within a certain range. In some embodiments, if the third time interval is beyond a certain range, the first communication mode may be considered abnormal, and there is a risk of network interruption.

The second frequency adjustment module 550 may be configured to adjust the second frequency based on the third time interval. In some embodiments, the second frequency is increased when the third time interval is greater than a fourth threshold. In some embodiments, when the third time interval is less than a fifth threshold, the second frequency is decreased. In some embodiments, the third time interval is greater than the fourth threshold, the third time interval may be considered to be beyond a normal range, the first communication mode is abnormal, and the client may increase the second frequency to ensure that the client updates the positioning information of the target normally. In some embodiments, if the third time interval is less than the fifth threshold, the first frequency may be deemed to have increased and the client may appropriately decrease the second frequency to reduce the burden on the server and waste of network resources. In some embodiments, the third time interval is not greater than the fourth threshold and is not less than the fifth threshold, and the second frequency may be kept unchanged. In some embodiments, the second frequency adjustment module 550 may increase the second frequency according to an instruction from the server to increase the second frequency. For example, the server may obtain a distance between the client and the target, and when the distance is less than or equal to a predetermined value, issue an instruction to increase the second frequency to the client, so as to increase the update frequency of the positioning information. And the client receives an instruction for increasing the second frequency from the server and increases the second frequency.

In some embodiments, the second frequency adjustment module 550 may be configured to obtain a distance between the client and the target, and increase the third frequency when the distance is less than or equal to a predetermined value. In some embodiments, the distance between the client and the target is a route distance. In some embodiments, the third frequency may be an update frequency of the client display positioning information. In some embodiments, the client may store the positioning information received through the first communication mode and the second communication mode, and display the positioning information at the client at a third frequency. For example, the predetermined value may be 100 meters, and in the online taxi appointment order, when the client (passenger) is within 100 meters of the target (driver), the passenger wants to know the position of the driver in real time, and at this time, the third frequency may be increased to speed up the update frequency of the positioning information at the client. In some embodiments, when it is detected that the distance between the target and the client is smaller than a set value, the first frequency and/or the second frequency may also be increased. For example, the first frequency and/or the second frequency may be increased while the third frequency is increased. For another example, the first frequency and/or the second frequency may be kept constant while the third frequency is increased.

It should be understood that the system and its modules shown in FIG. 5 may be implemented in a variety of ways. For example, in some embodiments, the system and its modules may be implemented in hardware, software, or a combination of software and hardware. Wherein the hardware portion may be implemented using dedicated logic; the software portions may be stored in a memory for execution by a suitable instruction execution system, such as a microprocessor or specially designed hardware. Those skilled in the art will appreciate that the methods and systems described above may be implemented using computer executable instructions and/or embodied in processor control code, such code being provided, for example, on a carrier medium such as a diskette, CD-or DVD-ROM, a programmable memory such as read-only memory (firmware), or a data carrier such as an optical or electronic signal carrier. The system and its modules of the present application may be implemented not only by hardware circuits such as very large scale integrated circuits or gate arrays, semiconductors such as logic chips, transistors, or programmable hardware devices such as field programmable gate arrays, programmable logic devices, etc., but also by software executed by various types of processors, for example, or by a combination of the above hardware circuits and software (e.g., firmware).

It should be noted that the above descriptions of the candidate item display and determination system and the modules thereof are only for convenience of description, and are not intended to limit the present application within the scope of the illustrated embodiments. It will be appreciated by those skilled in the art that, given the teachings of the present system, any combination of modules or sub-system configurations may be used to connect to other modules without departing from such teachings. For example, in some embodiments, for example, the third communication module 510, the fourth communication module 520, the positioning information updating module 530, the second detection module 540, the second frequency adjustment module 550, and the third frequency adjustment module 560 disclosed in fig. 5 may be different modules in one system, or may be a module that implements the functions of two or more modules described above. For example, the second detecting module 540 and the second frequency adjusting module 550 may be two modules, or one module may have both detecting and adjusting functions. For example, each module may share one memory module, and each module may have its own memory module. Such variations are within the scope of the present application.

Fig. 6 is an exemplary flow chart illustrating a method for updating a position fix in real time according to some embodiments of the present application. In some embodiments, flow 600 may be performed by processing logic that may comprise hardware (e.g., circuitry, dedicated logic, programmable logic, microcode, etc.), software (instructions run on a processing device to perform hardware simulation), etc., or any combination thereof. One or more operations of the process 600 for updating a location in real time illustrated in fig. 6 may be implemented by the location information service system 100 illustrated in fig. 1. For example, the flow 600 may be stored in the storage device 150 in the form of instructions and executed by the processing engine 112 to perform the calls and/or execute (e.g., the processor 220 of the computing device 200 shown in fig. 2, the central processor 340 of the mobile device 300 shown in fig. 3).

In step 610, positioning information of the target at different times may be obtained. In some embodiments, step 610 may be performed by acquisition module 410. In some embodiments, the target may refer to the service provider terminal 140. For example, in a network appointment service, the target may be a driver and the client may be a passenger. The passenger needs to know whether the driver has reached the specified starting position, where the driver's current position is. In a networked car appointment service platform, passengers want to be able to see the current position of the driver in real time. In some embodiments, the target may refer to the service requester terminal 130. For example, in a network appointment service, the target may be a passenger, and the client may be a driver who wishes to see the current location of the passenger in real time in the network appointment service platform, knowing how long the passenger has been in the place of origin in the order. In some embodiments, the location information of the target may be acquired by the navigation system 170 in the location information service system 100. For example, the target may communicate with the navigation system via its own positioning device to obtain its own positioning information. In some embodiments, the target may actively send the positioning information of different times to the server, and the server may update the positioning information of the target in real time when receiving the positioning information of the target. In some embodiments, the different time instants may refer to updating the positioning information at certain time intervals. For example, the positioning information of the target may be acquired every 0.05 seconds. In some embodiments, the different times may vary depending on distance or client requirements. For example, it is possible to acquire the positioning information of the target every 0.1 second when the distance between the target and the specified position is long, and to acquire the positioning information of the target every 0.05 second when the distance between the target and the specified position is short. In some embodiments, the location information of the target received by the server may be stored in the storage medium, and the location information of the target may be updated at a predetermined frequency different from the acquisition frequency. For example, if the server acquires the positioning information of the target once every time interval of 0.05 seconds. The acquired positioning information may be stored first, and the positioning information of the target is updated in the positioning information service platform every 0.1 second. In some embodiments, the positioning information may include position information of the target and timing information corresponding to the position information. In some embodiments, the location information may be latitude and longitude coordinates of the target, a geocode representing the location, or the like. In some embodiments, each location information has timing information corresponding thereto. For example, the corresponding time of the position information, or a group of position information is sorted in chronological order. In some embodiments, the latest positioning information may be obtained according to the timing information, and the positioning information may be updated.

In step 620, the positioning information may be transmitted to the client at a first frequency based on the first communication mode. In some embodiments, step 620 is performed by first communication module 420. In some embodiments, the first communication mode may be a PUSH mode, for example, the PUSH mode may be any one or combination of SMS-PUSH, WAP-PUSH, MMS-PUSH, HTTP server PUSH, persistent connection PUSH, FlashXMLSocket delivery, and the like. Namely, the server can actively send the positioning information of the target to the client without the inquiry of the client. In some embodiments, the first frequency may be related to a frequency at which the positioning information is acquired. For example, the first frequency may be equal to the frequency of acquiring the positioning information, i.e., the server transmits new positioning information to the client upon acquiring updated positioning information. In some embodiments, the first frequency and the frequency of acquiring the positioning information may be independent. For example, the server may acquire the location information of the target every 0.1 second. The first frequency may be 0.5 seconds, and the server sends the latest positioning information of the target to the client every 0.5 seconds. In some embodiments, the positioning information may be latitude and longitude coordinates of the target, a geocode representing a location, or the like. In some embodiments, the positioning information may include position information of the target and timing information corresponding to the position information. In some embodiments, each location information has timing information corresponding thereto. For example, the corresponding time of the position information, or a group of position information is sorted in chronological order. In some embodiments, the server may send all of the acquired location information to the client. For example, the server may send the acquired location information, the time sequence information corresponding to the location information, the time corresponding to the location information, or the positioning information arranged in time sequence within a period of time of the target to the client. In some embodiments, the server may optionally send the acquired location information to the client. For example, the server may send the location information acquired at that time and the timing information corresponding to the location information to the client. In some embodiments, the first frequency is variable. For example, the first frequency may be adjusted, increased or decreased under different circumstances or according to different requests of the client.

In step 630, a location information query request sent by the client at the second frequency may be obtained based on the second communication mode. In 640, the location information may be sent to the client in response to the location information query request based on the second communication mode. In some embodiments,

steps

630 and 640 are performed by the second communication module 430. In some embodiments, the second communication mode may be a Polling mode, for example, the Polling mode may be any one or a combination of Hub Polling (Hub Polling), round robin Polling (Roll call Polling), unicast Polling, multicast Polling, and Long Polling (Long Polling). Namely, the positioning information of the target is sent to the client according to the inquiry of the client. In some embodiments, the client sends an inquiry request for location information to the server at a second frequency. In some embodiments, the second frequency may be the same as the first frequency or may be different from the first frequency. For example, the first frequency may be greater than the second frequency, that is, the client updates the positioning information more frequently through the first communication mode, and updates the positioning information less frequently through the second communication mode. This helps to maintain both modes of communication while avoiding taking up too much network resources and burdening the server. Or the second frequency is greater than the first frequency, and the client updates the positioning information more frequently through the second communication mode. In some embodiments, the server sends the location information to the client in response to the location information query request based on the second communication mode. In some embodiments, the server does not receive the query request sent by the client, and does not send the location information of the target to the client through the second communication mode. In some embodiments, the second frequency is variable. For example, the client may adjust, increase or decrease the second frequency under different conditions or according to instructions issued by the server.

In some embodiments, the first communication mode and the second communication mode may be independent. The server can send the positioning information of the target to the client at a first frequency through the first communication mode, meanwhile, the server obtains inquiry information sent by the client through the second communication mode, and the positioning information of the target is sent to the client.

In some embodiments, the first communication mode and the second communication mode may be based on the first communication mode, and assisted by the second communication mode, to send the target location information to the client. For example, the server mainly sends the positioning information of the target to the client through the first communication mode. If the client is able to receive the location information via the first communication mode, no inquiry request is sent via the second communication mode. And if the client does not receive the positioning information of the target through the first communication mode, sending an inquiry request through the second communication mode, and receiving the positioning information through the second communication mode. To avoid display lag caused by long-term positioning information not being updated. In some embodiments, a preset time may be set, and if the client does not receive the location information of the target through the first communication mode for more than a preset time, the client automatically sends an inquiry request to the server through the second communication mode.

In some embodiments, the second communication mode may be the primary mode, and the first communication mode may be the secondary mode. For example, the client sends an inquiry request of the positioning information to the server at the second frequency, and the server sends the positioning information of the target to the client according to the inquiry request. If the server does not receive the inquiry request through the second communication mode, the server can actively send the positioning information to the client through the first communication mode so as to avoid the problem of lag in updating the positioning information of the client. In some embodiments, a preset time may be set, and if the server does not receive the inquiry request sent by the client over the preset time, the positioning information is automatically generated to the client through the first communication mode.

It should be noted that the above description is merely for convenience and should not be taken as limiting the scope of the present application. It will be understood by those skilled in the art that, having the benefit of the teachings of this system, various modifications and changes in form and detail may be made to the field of application for which the method and system described above may be practiced without departing from this teachings.

Fig. 7 is an exemplary flow chart illustrating adjusting a first frequency according to one embodiment of the present invention. In some embodiments, flow 700 may be performed by processing logic that may comprise hardware (e.g., circuitry, dedicated logic, programmable logic, microcode, etc.), software (instructions run on a processing device to perform hardware simulation), etc., or any combination thereof. One or more operations in the process 700 for adjusting the first frequency shown in fig. 7 may be implemented by the positioning information service system 100 shown in fig. 1. For example, the flow 700 may be stored in the storage device 150 in the form of instructions and executed by the processing engine 112 to perform the calls and/or perform the operations (e.g., the processor 220 of the computing device 200 shown in fig. 2, the central processor 340 of the mobile device 300 shown in fig. 3).

In 710, a first time interval during which a location information query request is obtained may be detected. In some embodiments, step 710 may be performed by the first detection module 440. In some embodiments, the first time interval may be a time interval between two adjacent positioning information inquiry requests sent by the client. In some embodiments, the first time interval and the second frequency should ideally be substantially identical. For example, if the second frequency is to send location information query requests every 0.5 seconds, the server would ideally receive one query request every 0.5 seconds. However, in practical situations, the data transmission process is complicated, and different time deviations occur when receiving or sending data, which even results in that the server cannot always stably and timely receive the inquiry request. If the deviation between the first time interval and the second frequency is within the normal range, the second communication mode can be considered to work normally, and the positioning information client sent by the server can receive the positioning information in time. If the second communication mode has a problem, the client cannot receive the positioning information for a long time or the server cannot receive the inquiry request of the client for a long time. In some embodiments, the first frequency may be adjusted according to the first time interval. The specific adjustment is as follows.

In 720, when the first time interval is greater than a first threshold, step 730 may be performed to increase the first frequency. In 740, when the first time interval is less than a second threshold, step 750 may be performed to decrease the first frequency. In some embodiments, step 720 and step 750 may be performed by the first frequency adjustment module 450. In some embodiments, if the first time interval is greater than the first threshold, the second communication mode may be considered to be unable to operate normally, and at this time, the first frequency of the first communication mode may be increased to ensure an update frequency of the client location information. In some embodiments, the first threshold may be significantly greater than the second frequency. For example, the second frequency may be that the interrogation request is sent every 0.5 seconds, and the first threshold may be 1 second. Similarly, if the second frequency of the client increases the second frequency of the second communication mode by adjustment, the first time interval is shortened, and when the first time interval is smaller than the second threshold, the first frequency of the first communication mode can be adjusted to reduce the first frequency, so that the client is ensured to update the target positioning information normally, and meanwhile, the server and the network are prevented from being burdened. For example, the second frequency may be increased from sending an interrogation request every 0.5 seconds to sending an interrogation request every 0.1 seconds, the server detects that the first time interval is found, the first time interval is less than the second threshold of 0.2 seconds, and may instruct to decrease the first frequency. In some embodiments, the first threshold and the second threshold may be set according to a second frequency, and the first threshold and/or the second threshold may be reset when the second frequency is changed. For example, when the second frequency is 1 second, the first threshold value may be set to 2 seconds, and the second threshold value may be set to 0.5; when the second frequency is 0.5 seconds, the first threshold value may be set to 1 second, and the second threshold value may be set to 0.3 seconds.

In some embodiments, step 720 and step 740 may not be in a sequential order, for example, steps 720 and 740 may be performed simultaneously to detect whether the first time interval is outside the range of the first threshold and the second threshold. Step 740 may be executed first, and then step 720 is executed, and it is detected whether the first time interval is smaller than the second threshold, and then it is detected whether the first time interval is larger than the first threshold. Step 720 may be performed first, and then step 740 may be performed. In some embodiments, only step 720 or step 740 may be performed, for example, detecting that the first time interval is found to be large for a period of time, approaching the vicinity of the first threshold, and detecting only whether the first time interval exceeds the first threshold. In some embodiments, the frequency of executing step 720 and step 740 may be different, for example, the main purpose of setting the first communication mode and the second communication mode to send the positioning information in parallel is to prevent the positioning information from being updated untimely due to sudden communication interruption, and therefore, the execution frequency of step 720 may be set to be much greater than the execution frequency of step 740, so as to achieve the purpose of finding the second communication mode working abnormally by detecting the first time interval in time. In some embodiments, only steps 720 and 730 may be performed, eliminating

steps

740 and 750. I.e. only to detect if the first time interval is greater than a first threshold value and if so, to increase the first frequency.

In some embodiments, the first time interval is not greater than the first threshold and is not less than the second threshold, and step 760 may be performed to leave the first frequency unchanged. In some embodiments, step 760 may be performed by first frequency adjustment module 450.

Fig. 8 is another exemplary flow chart illustrating adjusting a first frequency according to one embodiment of the present invention. In some embodiments, flow 800 may be performed by processing logic that may comprise hardware (e.g., circuitry, dedicated logic, programmable logic, microcode, etc.), software (instructions run on a processing device to perform hardware simulation), etc., or any combination thereof. One or more operations of another process 800 for adjusting a first frequency, shown in fig. 8, may be implemented by the positioning information service system 100 shown in fig. 1. For example, the flow 800 may be stored in the storage device 150 in the form of instructions and executed and/or invoked by the processing engine 112 (e.g., the processor 220 of the computing device 200 shown in fig. 2, the central processor 340 of the mobile device 300 shown in fig. 3).

At 810, a distance between the client and the target may be obtained. In some embodiments, step 810 may be performed by first frequency adjustment module 450. In some embodiments, the location coordinates of the client and the target may be obtained, and the distance between the client and the target may be determined. In some embodiments, the distance between the client and the target may be a straight line distance or may be an actual route distance. In some embodiments, the distance between the client and the target is a route distance.

In 820, when the distance is less than or equal to a predetermined value, step 830 is performed to increase the first frequency to increase the update frequency of the positioning information. In some embodiments,

steps

820 and 830 may be performed by first frequency adjustment module 450. In some embodiments, a distance between the client and the target may be obtained, and when the distance is less than or equal to a predetermined value, the first frequency is increased to increase the update frequency of the positioning information. For example, the predetermined value may be 100 meters, and in the online booking order, when the client (passenger) is within 100 meters of the target (driver), in order for the passenger to know the position of the driver in real time, the first frequency may be increased, so as to speed up the update frequency of the positioning information.

When the distance is greater than the predetermined value, the first frequency may be maintained unchanged at 840. Step 840 may be performed by first frequency adjustment module 450 in some embodiments.

Fig. 9 is an exemplary flow chart illustrating adjusting a second frequency according to one embodiment of the present invention. In some embodiments, flow 900 may be performed by processing logic that may comprise hardware (e.g., circuitry, dedicated logic, programmable logic, microcode, etc.), software (instructions run on a processing device to perform hardware simulation), etc., or any combination thereof. One or more operations of the procedure 900 for adjusting the second frequency shown in fig. 9 may be implemented by the positioning information service system 100 shown in fig. 1. For example, the flow 900 may be stored in the storage device 150 in the form of instructions and executed by the processing engine 112 to perform the calls and/or perform the operations (e.g., the processor 220 of the computing device 200 shown in fig. 2, the central processor 340 of the mobile device 300 shown in fig. 3).

At 910, a distance between the client and the target may be obtained. In some embodiments, step 910 may be performed by first frequency adjustment module 450. In some embodiments, the distance between the client and the target is a route distance.

In 920, when the distance is less than or equal to a predetermined value, step 930 may be executed to issue an instruction to increase the second frequency to the client, so as to increase the update frequency of the positioning information. In some embodiments,

steps

920 and 930 may be performed by first frequency adjustment module 450. In some embodiments, a distance between the client and the target may be obtained, and when the distance is less than or equal to a predetermined value, an instruction to increase the second frequency is issued to the client to increase the update frequency of the positioning information. For example, the predetermined value may be 100 meters, and in the online booking order, when the client (passenger) is within 100 meters of the target (driver), the client (passenger) can know the position of the driver in real time, and the server sends an instruction for increasing the second frequency to the client.

At 940, when the distance is greater than the predetermined value, the instruction for adjusting the second frequency may not be issued, or the instruction for keeping the second frequency unchanged may be issued to the client. Step 840 may be performed by first frequency adjustment module 450 in some embodiments.

FIG. 10 is an exemplary flow diagram illustrating real-time display positioning according to one embodiment of the present invention. In some embodiments, flow 1000 may be performed by processing logic that may comprise hardware (e.g., circuitry, dedicated logic, programmable logic, microcode, etc.), software (instructions run on a processing device to perform hardware simulation), etc., or any combination thereof. One or more operations of the process 1000 for displaying positioning in real time illustrated in fig. 10 may be implemented by the positioning information service system 100 illustrated in fig. 1. For example, the process 1000 may be stored in the storage device 150 in the form of instructions and executed by the processing engine 112 to perform the calls and/or perform the operations (e.g., the processor 220 of the computing device 200 shown in fig. 2, the central processor 340 of the mobile device 300 shown in fig. 3).

In 1010, location information for an object transmitted by a server at a first frequency may be received based on a first communication mode. In some embodiments, step 1010 may be performed by the third communication module 510. In some embodiments, the first communication mode may be a push mode. In some embodiments, a first communication channel between the server and the client may be established first based on the first communication mode, after which the server may send the location information of the target to the client at the first frequency without the client issuing an inquiry request. In some embodiments, the client may first send a subscription request to the server for subscribing to the target location information via the first communication mode. Based on the subscription request, a communication channel of a first communication mode is established between the server and the client, and the server actively sends the positioning information of the target to the client at a first frequency periodically after receiving the updated positioning information of the target. In some embodiments, when the communication access in the first communication mode needs to be closed and the positioning information is no longer received, the client needs to send a request for unsubscribing to the server, and the server stops sending the positioning information to the client only when receiving the request for unsubscribing sent by the client.

At 1020, a location information query request related to the object may be sent to the server at a second frequency based on a second communication mode. In 1030, the location information of the target to which the server replies may be received based on the second communication mode. In some embodiments,

steps

1020 and 1030 may be performed by the fourth communication module 520. In some embodiments, the second communication mode may be a polling mode. The client needs to continuously send an inquiry request to the server when the client wants to acquire the positioning information of the target. The server receives an inquiry request of the client and then responds to the inquiry request, and sends the current positioning information to the client. If the client does not send an inquiry request, the server will not send the location information to the client. Therefore, when the client needs to know the real-time positioning information of the target, the client needs to continuously send an inquiry request to the server. In some embodiments, even if the location information of the target is not updated at the server side, the server receives the query request from the client side, and sends the current latest location information to the client side, and the current latest location information may be the same as the location information sent to the client side last time. In some embodiments, even if the location information of the target is updated at the server side, the server does not send the updated location information to the client side as long as the server does not receive the inquiry request of the client side. In some embodiments, if the client wants to turn off the second communication mode, it only needs to stop sending the query request of the target location information.

In 1040, the location information of the target may be displayed updated at a third frequency. In some embodiments, step 1040 may be performed by the positioning information update module 530. In some embodiments, the positioning information may include position information of the target and timing information corresponding to the position information. In some embodiments, the timing information may be a specific time. For example, the timing information corresponding to the a-position information may be 21 minutes 15.0 seconds at 10 am on 8/2018, and the timing information corresponding to the B-position information may be 21 minutes 15.5 seconds at 10 am on 8/2018. Which positioning information is the latest can be distinguished from the timing information. In some embodiments, the timing information may be a sequence of the position information arranged in a front-to-back order. For example, the timing information corresponding to the a-position information is 1011, the timing information corresponding to the B-position information is 1012, the timing information may be a sequence of increasing numbers, and the positioning information is updated as the number value of the number is larger. In some embodiments, the timing information in the positioning information is represented in a consistent manner, that is, the positioning information received in the first communication mode and the second communication mode both include timing information with consistent representation. The client can find the latest positioning information according to the time sequence information and update the positioning information of the target. In some embodiments, the frequency at which the client updates the location information is a third frequency. In some embodiments, the third frequency may be the same as the first frequency or the second frequency. In some embodiments, the third frequency may be different from the first frequency or the second frequency. In some embodiments, the client receives the positioning information sent by the server, the positioning information may be stored in a memory (the memory 360, the storage unit 390, the rom 230 or the ram 240) of the client, and the positioning information updating module 530 obtains the latest positioning information in the memory, and updates the latest positioning information at the client according to a third frequency.

Fig. 11 is an exemplary flow chart illustrating a first frequency adjustment according to an embodiment of the present invention. In some embodiments, flow 1100 may be performed by processing logic that may comprise hardware (e.g., circuitry, dedicated logic, programmable logic, microcode, etc.), software (instructions run on a processing device to perform hardware simulation), etc., or any combination thereof. One or more operations in the flow 1100 for first frequency adjustment shown in fig. 11 may be implemented by the positioning information service system 100 shown in fig. 1. For example, the process 1100 may be stored in the storage device 150 in the form of instructions and executed by the processing engine 112 to perform the calls and/or perform the operations (e.g., the processor 220 of the computing device 200 shown in fig. 2, the central processor 340 of the mobile device 300 shown in fig. 3).

In step 1110, a second time interval between sending the location information query request and receiving the location information of the server reply may be detected. In some embodiments, step 1110 may be performed by the second detection module 540. In some embodiments, the second time interval is dependent on the speed of response of the server after receiving the query request and the network status. For example, if the server responds to the location information immediately upon receiving the query request, the second time interval directly reflects the quality of the network communication status. And when the network communication state is good, the second time interval is short, otherwise, the second time interval is longer. In some embodiments, in the actual transmission process, if the second time interval is stable within a certain normal range, it may be considered that the second communication mode is working normally, the server may receive the query request sent by the client, and the client may receive the location information of the response sent by the server in time. In some embodiments, if the second time interval is long, even if the client does not receive any response message, it indicates that the second communication mode is operating abnormally.

In 1120, if the second time interval is greater than the third threshold, step 1130 is performed to send a request to the server to increase the first frequency. In some embodiments,

steps

1120 and 1130 may be performed by the second detection module 540. In some embodiments, if the second time interval is greater than the third threshold, the second communication mode may be considered to be abnormal, and the client may not receive the response positioning information sent by the server. In some embodiments, a request to increase the first frequency may be sent to the server to increase the first frequency of the first communication mode, ensure that the client can still receive the location information, and ensure an update frequency of the location information. In some embodiments, the third threshold may be greater than the second frequency. For example, when the second frequency is that the inquiry request is sent to the server every 0.5 seconds, if the second time interval exceeds 0.5 seconds, it can be considered that the second communication mode is abnormal, and there is a risk of interruption. The client may send a request to the server to increase the first frequency.

In 1140, if the second time interval is not greater than the third threshold, the request to change the first frequency may not be sent, and the request to maintain the first frequency unchanged may also be sent. In some embodiments, step 760 may be performed by the second detection module 540.

Fig. 12 is an exemplary flow chart illustrating adjusting the second frequency according to an embodiment of the present invention. In some embodiments, flow 1200 may be performed by processing logic that may comprise hardware (e.g., circuitry, dedicated logic, programmable logic, microcode, etc.), software (instructions run on a processing device to perform hardware simulation), etc., or any combination thereof. One or more operations in the flow 1200 for second frequency adjustment shown in fig. 12 may be implemented by the positioning information service system 100 shown in fig. 1. For example, the process 1200 may be stored in the storage device 150 in the form of instructions and executed by the processing engine 112 to perform the calls and/or perform the operations (e.g., the processor 220 of the computing device 200 shown in fig. 2, the central processor 340 of the mobile device 300 shown in fig. 3).

In step 1210, a third time interval of receiving positioning information of the target transmitted by the server based on the first communication mode may be detected. In some embodiments, step 1210 may be performed by the second detection module 540. In some embodiments, the third time interval is a time interval between two adjacent positioning information sent by the server in the first communication mode. In some embodiments, the client may detect a third time interval, and adjust the second frequency based on the third time interval. In some embodiments, the first communication mode may be considered to be operating properly if the third time interval is stable within a certain range. In some embodiments, if the third time interval is outside a certain range, the first communication mode may be considered abnormal, and there is a risk of interruption.

In step 1220, if the third time interval is greater than the fourth threshold, step 1230 may be performed to increase the second frequency; in step 1240, if the third time interval is less than the fifth threshold, step 1250 may be performed to decrease the second frequency. In some embodiments, the steps 1220-1250 may be performed by the second frequency adjustment module 550. In some embodiments, the third time interval is greater than the fourth threshold, the third time interval may be considered to be beyond a normal range, the first communication mode is abnormal, and the client may increase the second frequency to ensure that the client updates the positioning information of the target normally. In some embodiments, if the third time interval is less than the fifth threshold, the first frequency may be deemed to have increased and the client may appropriately decrease the second frequency to reduce the burden on the server and waste of network resources.

In some embodiments, step 1220 and step 1240 may not be in order of precedence. In some embodiments, step 1220 and step 1240 may be performed simultaneously, detecting whether the third time interval is outside the range of the fourth threshold and the fifth threshold. Step 1240 may be executed first, and then step 1220 may be executed, and it is detected whether the third time interval is smaller than the fifth threshold, and then it is detected whether the third time interval is larger than the fourth threshold. Step 1220 may be performed first, and then step 1240 may be performed. In some embodiments, only step 1220 or step 1240 may be performed, for example, detecting that the third time interval is found to be large enough to approach the vicinity of the fourth threshold for a period of time, and detecting only whether the third time interval exceeds the fourth threshold. In some embodiments, the frequency of executing step 1220 and step 1240 may be different, for example, the primary purpose of setting the first communication mode and the second communication mode to transmit the positioning information in parallel is to prevent the positioning information from being updated untimely due to sudden communication interruption, and therefore, it may be set that the execution frequency of step 1220 is much greater than the execution frequency of step 1240, so as to achieve the purpose of discovering the first communication mode working abnormally by detecting the third time interval in time. In some embodiments, only steps 1220 and 1230 may be performed, eliminating

steps

1240 and 1250. I.e. only to check whether the third time interval is greater than a fourth threshold value and, if so, to increase the second frequency.

In some embodiments, the third time interval is not greater than the fourth threshold and is not less than the fifth threshold, and step 1260 may be performed to leave the second frequency unchanged. In some embodiments, step 1260 may be performed by the second frequency adjustment module 550.

Fig. 13 is an exemplary flow chart illustrating an adjustment of the third frequency according to an embodiment of the present invention. In some embodiments, flow 1300 may be performed by processing logic that may comprise hardware (e.g., circuitry, dedicated logic, programmable logic, microcode, etc.), software (instructions run on a processing device to perform hardware simulation), etc., or any combination thereof. One or more operations in the process 1300 for third frequency adjustment shown in fig. 13 may be implemented by the positioning information service system 100 shown in fig. 1. For example, the process 1300 may be stored in the storage device 150 in the form of instructions and executed and/or invoked by the processing engine 112 (e.g., the processor 220 of the computing device 200 shown in fig. 2, the central processor 340 of the mobile device 300 shown in fig. 3).

In step 1310, the distance between the client and the target may be obtained. In some embodiments, step 1310 may be performed by the second frequency adjustment module 550. In some embodiments, the location coordinates of the client and the target may be obtained, and the distance between the client and the target may be determined. In some embodiments, the distance between the client and the target is a route distance.

In step 1320, when the distance is less than or equal to a predetermined value, step 1330 may be performed to increase the third frequency. In some embodiments, step 1310 may be performed by the second frequency adjustment module 550. In some embodiments, a distance between the client and the target may be obtained, and when the distance is less than or equal to a predetermined value, the third frequency is increased to increase the frequency of updating and displaying the positioning information by the client. For example, the predetermined value may be 100 meters, and in the online taxi appointment order, when the client (passenger) is within 100 meters of the target (driver), in order for the passenger to know the position of the driver in real time, the third frequency may be increased, so as to speed up the update frequency of the positioning information at the client. In some embodiments, when it is detected that the distance between the target and the client is smaller than a set value, the first frequency and/or the second frequency may also be increased. For example, the first frequency and/or the second frequency may be increased while the third frequency is increased. For another example, the first frequency and/or the second frequency may remain unchanged while the third frequency is increased.

In 1340, the second frequency and/or the third frequency are kept unchanged when the distance is greater than the predetermined value. Step 1340 may be performed by the second frequency adjustment module 550 in some embodiments.
