The cloud application refers to that the application is placed on a cloud server to run based on a cloud computing technology, and the rendered program picture is compressed and encoded by the cloud server and then transmitted to the user terminal through a network. The cloud application may be a cloud education application, a cloud gaming application, or the like. Taking cloud game application as an example, the cloud game runs on a cloud server, audio and video data rendered by the game are compressed and encoded, then the compressed and encoded audio and video data are transmitted to a user terminal through a network, and a user terminal decodes an encoded file and renders the encoded file to a display screen for display. However, since the cloud game runs on a cloud server, which is usually deployed in a computer room, the cloud game cannot acquire the location information of the terminal, so that the game depending on the location information cannot be experienced. It can be seen that the current cloud application cannot share the location information of the terminal.

The cloud computing technology is a computing mode, and distributes computing tasks on a resource pool formed by a large number of computers, so that various application systems can acquire computing power, storage space and information services according to needs. The network that provides the resources is referred to as the "cloud". Resources in the "cloud" appear to the user as being infinitely expandable and available at any time, available on demand, expandable at any time, and paid for on-demand. As a basic capability provider of cloud computing, a cloud computing resource pool (called as a cloud Platform in general, an Infrastructure as a Service) Platform is established, and multiple types of virtual resources are deployed in the resource pool for selective use by external clients, the cloud computing resource pool mainly includes a computing device (including an operating system, for a virtualized machine), a storage device, and a network device, and is divided according to logical functions, a PaaS (Platform as a Service) layer may be deployed on an IaaS (Infrastructure as a Service) layer, a SaaS (Software as a Service) layer may be deployed on the PaaS layer, or the SaaS may be directly deployed on the IaaS layer, the PaaS may be a Platform running on Software, such as a web database, a container, and the like, as business Software of various websites, a web portal, and the like, SaaS and PaaS are upper layers relative to IaaS.

The cloud game may also be called a game on demand (gaming), which is an online game technology based on a cloud computing technology. Cloud game technology enables light-end devices (thin clients) with relatively limited graphics processing and data computing capabilities to run high-quality games. In a cloud game scene, a game is not operated in a player game terminal but in a cloud server, and the cloud server renders the game scene into a video and audio stream which is transmitted to the player game terminal through a network. The player game terminal does not need to have strong graphic operation and data processing capacity, and only needs to have basic streaming media playing capacity and capacity of acquiring player input instructions and sending the instructions to the cloud server.

In order to solve the technical problem that the cloud application cannot share the location information of the terminal, embodiments of the present application provide a location information obtaining method and apparatus, an electronic device, and a storage medium. Therefore, the purpose of sharing the position information of the terminal by the cloud application is achieved.

The position information acquisition method provided by the embodiment of the application can be used in scenes such as cloud education, cloud live broadcast and cloud games, can be used on a server side and can also be used on a terminal side, wherein the terminal side provides a client for accessing cloud application, and the client can run in a terminal operated by a user. The server related to the embodiment of the application can be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, and can also be a cloud server providing basic cloud computing services such as cloud service, a cloud database, cloud computing, cloud functions, cloud storage, network service, cloud communication, middleware service, domain name service, security service, CDN (content delivery network), a big data and artificial intelligence platform and the like. The terminal related to the embodiment of the application can be a smart phone, a tablet computer, a notebook computer, a desktop computer, a smart sound box, a smart watch, and the like, but is not limited thereto. The terminal and the server may be directly or indirectly connected through wired or wireless communication, and the application is not limited herein.

The position information obtaining method provided by the embodiment of the present application is executed by a position information obtaining device, the position information obtaining device may operate in the system architecture shown in fig. 1, and fig. 1 is a system architecture diagram of the position information obtaining device provided by the embodiment of the present application. The system comprises a cloud server and a terminal, wherein the cloud server can be a container or a virtual machine for operating an android system, the terminal provides a client for accessing cloud application, the terminal supports different positioning systems, and an operating system of the terminal is not limited. The cloud server comprises a Hardware Abstraction Layer (HAL), a Framework Layer (Framework) and an Application Layer (App), and the terminal comprises a physical Hardware Layer, a Linux kernel Layer, a Hardware Abstraction Layer, a Framework Layer and an Application Layer. In one scenario, the location information may be transmitted as follows:

first, on the terminal side: a Global Positioning System (GPS) device in a physical hardware layer acquires position information of a current terminal, and sends the position information to a cloud game App in an application layer through a GPS driver in a Linux kernel layer, a data monitoring thread in a hardware abstraction layer, a position Provider (Location Provider) and a position Manager Service (Location Manager Service) in a framework layer, and a position Manager (Location Manager) in the application layer, and the cloud game App sends the acquired position information to a cloud game business process in the application layer of a cloud server;

then, on the cloud server side: after receiving the position information, the cloud game business process sends the position information to the game App in the application layer sequentially through the data monitoring thread in the hardware abstraction layer, the position provider and the position manager service in the framework layer and the position manager service in the application layer, so that the game App running on the cloud server can acquire the position information of the terminal. The hardware abstraction layer of the cloud server is different from the hardware abstraction layer of the terminal, the hardware abstraction layer of the cloud server is mainly used for creating a data monitoring thread, monitoring commands and position information forwarded by a cloud game service process through the data monitoring thread, executing a corresponding callback function after analyzing the position information, and transmitting the analyzed position information to a position provider in a framework layer of the cloud server, and the hardware abstraction layer of the terminal is mainly used for calling the position information of the terminal and transmitting the called position information to the framework layer of the terminal. The position provider in the framework layer of the cloud server and the position provider in the framework layer of the terminal have the same function, and both provide received position information for corresponding position manager services, and the position manager services in the framework layer of the cloud server and the position manager services in the framework layer of the terminal have the same function, and both provide positioning service functions.

It should be understood that the cloud game App in the application layer of the terminal does not need to be installed locally, and the game App in the application layer of the cloud server needs to be installed.

With reference to the above system architecture, the following describes a location information obtaining method in an embodiment of the present application through a cloud server side, please refer to fig. 2, where fig. 2 is a flowchart of a location information obtaining method provided in an embodiment of the present application, and the embodiment of the present application at least includes the following steps:

201. acquiring a starting request sent by a terminal; the starting request is used for requesting to start a position service control in the cloud server;

in this embodiment, when the terminal requests access to the cloud application through the client, the terminal may send an opening request of the location service control to the cloud server, so that the cloud server receives the opening request sent by the terminal. The number of the terminals may be 1 or more, and is not limited herein. Different terminals may access the same cloud application, and may also access different cloud applications, which is not limited herein. The location service control is provided by the cloud server, the location service control is usually located in a framework layer of the cloud server, the cloud application is usually located in an application layer of the cloud server, and an interface is provided between the framework layer and the application layer, so that information (such as location information) is transmitted from the framework layer to the application layer. The location service control provides location service function, also called positioning service, which is a location-related service provided by wireless operation company for users. The cloud server can keep a complete position service function and can default to the authorized positioning authority, so that the interference of positioning authority popup is avoided in the running process of the cloud application. The default authorized positioning permission means that the cloud server defaults that the cloud application opens the positioning permission of the terminal. Considering that a plurality of cloud applications in an actual scene can request the position information of a terminal in the running process, and the request can be presented on a display interface of a user terminal in a pop-up window form, which can cause certain interference on the user experience of the cloud applications, the cloud server can open the positioning authority of the terminal for the cloud applications by default, so as to avoid the interference of the pop-up window of the positioning authority. For example, when a user logs in a cloud application a for the first time through a mobile phone, if the cloud server does not default that the cloud application a starts the positioning authority of the mobile phone, the cloud application a displays the following contents on a login interface of a cloud application of a terminal in a popup mode: allow "cloud application a" access to your location? And provides the user with three options: only during use of the application, always allowed, not allowed. The user needs to manually select from the three options to smoothly perform the next operation. In this embodiment, the cloud server defaults that the cloud application a starts the positioning authority of the mobile phone, so that the user is not interfered by a positioning authority popup window in the whole process of using or experiencing the cloud application a, on one hand, time spent on accessing the cloud application a can be saved, and on the other hand, user experience is improved.

In one scenario, a user starts a cloud application on a mobile phone, and after a cloud application login interface is displayed, a terminal of the cloud application sends a start request of a position service control to a cloud server. Specifically, a cloud game is taken as an example for explanation, as shown in fig. 3a and fig. 3b, fig. 3a is a schematic diagram of a cloud game login interface provided in the embodiment of the present application, and fig. 3b is a schematic diagram of a cloud game control interface provided in the embodiment of the present application. After a player opens the game of 'together XX' on the mobile phone, a game login interface shown in fig. 3a is displayed, a floating button is arranged on the right side of the game login interface, the player clicks the floating button to pop up a game control interface shown in fig. 3b, and control components displayed on the game control interface have image quality, opening positioning and sharing. When the player opens the opening positioning, the terminal sends an opening request of the position service control to the cloud server. It can be understood that when the player turns off the "open positioning", the terminal sends a closing request of the location service control to the cloud server; when the player opens the "image quality", if the "image quality" is set to 1080P image quality, the terminal presents the game picture according to the 1080P image quality, and when the player opens the "share", the player can be provided with a plurality of different types of receivers to share the game to the receivers. It should be understood that in some possible scenarios, after a player opens a game of "XX together" on a mobile phone, a terminal defaults to automatically send a start request of a location service control to a cloud server, and does not need to actively trigger "open positioning" by the player to accelerate sending of the start request of the location service control to the cloud server, which is beneficial to improving location information acquisition efficiency.

202. Opening the position service control according to the opening request to acquire initial position information; the position service control is used for providing position information of the terminal for cloud application, and the initial position information is preset initial position information for the terminal;

in this embodiment, after receiving a start request of a location service control sent by a terminal, a cloud server starts the location service control according to the start request. The position service control of the cloud server is mainly used for providing position information of the terminal for the cloud application, the position information of the position service control mainly comes from the position information sent by the terminal, and after the position service control obtains the position information sent by the terminal, the cloud application running on the cloud server can also obtain the position information of the terminal.

In addition, considering that part of the cloud applications cannot display the application scene under the condition that the position information cannot be acquired, for example, part of the cloud games cannot display the game scene under the condition that the position information cannot be acquired, before the cloud applications receive the position information of the terminal, the position service control of the cloud server keeps default position information (initial position information) for the cloud applications to acquire, so that the cloud applications can smoothly display the application scene on the display interface of the terminal, and in addition, the method is also beneficial to accelerating the entering of the application scene and reducing the waiting time for entering the application scene. Therefore, the initial position information is the position information provided by the position service control of the cloud server to the cloud application before the cloud application receives the position information of the terminal. In an actual scenario, the initial position information may be set by a user, for example, the initial position information is set to "beijing", "shenzhen", and the like, which is not limited herein. The initial position information may be set to be multiple, and when the initial position information needs to be determined, the cloud server may randomly select from the multiple initial position information.

203. Sending the opening information of the position service control to the terminal;

in this embodiment, after the location service control is started, the cloud server sends the start information of the location service control to the terminal. In consideration of the possibility that the position service control is failed to be opened in practical application, if the position service control is failed to be opened, the terminal sends the current position information of the terminal to the cloud server, which cannot be provided for the cloud application, so that the current position information of the terminal is frequently sent in order to avoid the terminal being invalid, and network resources are saved, and therefore the cloud server is required to send the opening information of the position service control to the terminal after the position service control is opened.

204. Acquiring current position information of the terminal sent by the terminal; the current position information of the terminal is the position information obtained after the terminal determines that the position service control is successfully started according to the starting information;

in this embodiment, after the opening information of the location service control is sent to the terminal, the terminal determines whether the location service control is successfully opened according to the opening information, and if it is determined that the location service control is successfully opened, the terminal acquires current location information and sends the current location information to the cloud server, so that the cloud server acquires the current location information of the terminal. It can be understood that if the terminal determines that the location service control is not successfully started, the terminal does not send the current location information to the cloud server, and the terminal can select to resend the start request of the location service control so as to resend the request of the cloud server for starting the location service control. The terminal can acquire the position information of itself through various modes such as a GPS, a base station, a wireless network and the like. In an actual scene, the terminal may obtain the current position information in real time, or the terminal may obtain the current position information according to a preset time interval or a preset frequency. Since the position of the terminal may change with time, the current position information is usually a dynamic position information, and the position information at different time points may be different or the same.

It should be noted that the current location information generally includes a time stamp (also referred to as a timestamp). The time stamp is data generated by using a data signature technology, a signature object comprises information such as original file information, signature parameters, signature time and the like, and the time stamp is mainly used for authenticating the data generation time through a certain technical means so as to verify whether the data is falsified after being generated.

In some possible embodiments, the step 204 of obtaining the current location information of the terminal sent by the terminal includes:

Specifically, considering that the data volume of the current position information acquired by the terminal is relatively large, some redundant data (for example, data of a plurality of search satellites before the position positioning is successful) exists in the current position information, and the cloud application needs to preferentially ensure the transmission bandwidth of the audio/video stream, if the data amount of the current location information is too large, the overall transmission bandwidth is affected, and in order to solve the technical problem, in some embodiments, the current location information sent by the terminal to the cloud server is sent in a data packet form, and the terminal needs to perform serialization processing on the current location information before sending the current location information to the cloud server, and then packaging the current position information of the terminal after the serialization processing according to a preset protocol (such as a private protocol such as a SUBCMD _ LOCATION _ UPDATE protocol) to obtain a data packet, and finally sending the data packet to a cloud server. After receiving the data packet, the cloud server analyzes the data packet to obtain the analyzed current position information (such as longitude, latitude, altitude, azimuth, and the like). It should be understood that by performing serialization processing on the current position information, redundant data in the current position information can be removed, transmission bandwidth can be saved, and by encapsulating the current position information after serialization processing, transmission bandwidth is further reduced, so that the transmission bandwidth of audio and video streams of cloud application is ensured.

When the terminal needs to transmit the current position information through the network or needs to persist the current position information so as to be used in the future, the current position information can be serialized, the serialization processing of the current position information refers to a process of converting the current position information into a byte sequence (binary byte) which can be kept or transmitted, the deserialization corresponds to the serialization, the deserialization refers to a process of converting a binary byte generated in the serialization process into the current position information, and the serialization and the deserialization are combined to realize data storage and transmission. In the data transmission process that the terminal sends the current position information to the cloud server, the current position information can be processed according to a default serialization mode generally, so that the close coupling of the position information and the serialization is realized.

205. And updating the initial position information provided by the position service control into the current position information of the terminal.

In this embodiment, after receiving the current location information sent by the terminal, the cloud server provides the current location information of the terminal to the location service control, and after the location service control obtains the current location information of the terminal, the location service control updates the initial location information provided by the location service control to the current location information of the terminal, so that the cloud application can obtain the current location information of the terminal. In a scene, after the cloud application acquires the current position information of the terminal, the current position information of the terminal can be rendered in real time, and then the current position information is transmitted to the terminal through the cloud server through the network for rendering presentation, so that the current position information can be displayed on a display interface of the terminal. Specifically, on the basis of fig. 3a and 3b, as shown in fig. 3c, fig. 3c is an interface schematic diagram for displaying location information in a cloud game scene provided in the embodiment of the present application, if a location service control is successfully started, a terminal will display the game scene on the display interface, and current location information will be displayed in the game scene, and the current location information displayed in fig. 3c is "shenzhen nan shan district XX street".

In some possible embodiments, step 205 updates the location information provided by the location service control to the current location information of the terminal, and then includes:

closing the position service control according to the closing request;

Specifically, after the cloud application acquires the location information of the terminal, the cloud server may receive a closing request of the location service control sent by the terminal at a certain time point, for example, at a certain time point, a user closes the cloud application, the user exits the cloud application, the user requests to close the positioning service, a network is suddenly disconnected, and the like, which may trigger the terminal to send the closing request of the location service control to the cloud server, the cloud server closes the location service control according to the received closing request, and then sends the closing information of the location service control to the terminal, and after the terminal receives the closing information, if it is determined that the location service control is successfully closed, the terminal stops sending the location information. It should be noted that in some scenarios, after the terminal sends the closing request of the location service control to the cloud server, the terminal directly stops sending the location information without waiting for receiving the closing information sent by the cloud service. In other scenes, when the user closes the cloud application, the user exits the cloud application, and the user requests to close the positioning service and suddenly disconnect the network, the terminal directly stops sending the position information. Therefore, after the terminal sends the closing request of the position service control to the cloud server, the cloud server closes the position service control according to the closing request, the position service control of the cloud server is prevented from being always in an open state in some scenes, and therefore the operation burden of the cloud server is relieved.

According to the scheme provided by the embodiment of the application, after the cloud server starts the position service control, the position information can be provided for the cloud application through the position service control, so that after the cloud server obtains the current position information of the terminal, the current position information of the terminal is provided for the cloud application through the position service control, and the cloud application can obtain the current position information of the terminal. Therefore, the purpose of sharing the position information of the terminal by the cloud application is achieved.

Referring to fig. 4, fig. 4 is an interaction schematic diagram of another location information acquisition method provided in the embodiment of the present application, where the location information acquisition method according to the embodiment of the present application is introduced from the perspective of information interaction between a cloud server side and a terminal side, and the embodiment of the present application at least includes the following steps:

401. the terminal sends an opening request to the cloud server; the starting request is used for requesting to start a position service control in the cloud server;

in this embodiment, when the terminal requests access to the cloud application through the client, the terminal may send an opening request of the location service control to the cloud server. The protocol adopted by the position service control opening request sent by the terminal to the cloud server may be: SUBCMD _ GPS _ ON _ REQ. Wherein, SUBCMD _ GPS _ ON _ REQ is a private protocol.

The cloud server may be a container or a virtual machine running an android system, and the client may be a client of an App on an android device or an IOS device supporting a GPS positioning system.

402. The cloud server starts the position service control according to the starting request to acquire initial position information;

in this embodiment, the location service control is configured to provide location information of the terminal to the cloud application, where the initial location information is initial location information preset for the terminal.

403. The cloud server sends the opening information of the position service control to the terminal;

in this embodiment, the opening information of the location service control sent by the cloud server to the terminal may be: SUBCMD _ GPS _ ON _ RSP. The SUBCMD _ GPS _ ON _ RSP refers to the cloud server sending a Global Positioning System (GPS) ON reply.

404. If the terminal determines that the position service control is successfully started according to the starting information, current position information is obtained;

in an actual application scenario, the terminal may acquire the current location information by using the following network protocol:

if the terminal is an android device, current position information is acquired through the following steps:

1) requesting ACCESS _ FINE _ LOCATION, ACCESS _ COARSE _ LOCATION to ACCESS the right related to the LOCATION information;

wherein, android provides two types of location permissions:

acquiring an accurate positioning authority feature (ACCESS _ FINE _ LOCATION) and acquiring a COARSE positioning authority feature (ACCESS _ COARSE _ LOCATION), wherein ACCESS _ FINE _ LOCATION refers to determining a position (LOCATION) as accurately as possible by using an available LOCATION provider including a GPS and a Wireless Local Area Network (WLAN) and mobile data traffic, and ACCESS _ COARSE _ LOCATION refers to determining position information by using the WLAN and/or mobile data traffic, and the accuracy of the position information is not high and is equivalent to positioning accuracy at a city block level.

2) Obtaining a LocationManager: an application layer management class of location services controls;

the location manager (LocationManager) refers to a management class in android that accesses a system location service control, and can be obtained through a contextual location service.

3) Creating a Location data monitoring class and realizing a Location Listener interface function onlocation changed;

the Location data monitoring class is created by mainly creating a Location listening (Location listener) interface to monitor the change of the Location (such as GPS and WLAN) and dynamically acquire the Location information in real time. Location changed refers to a callback function that is automatically called when the Location changes, where Location records the latest Location information.

4) Adding Location data monitoring: calling requestLocationUpdates;

wherein, Location data listening is realized by calling request Location updates (requestLocationUpdates).

5) And monitoring a callback function: onLocationChanged acquires Location data.

The callback function may be onLocationChanged by listening to the callback function to obtain Location data.

If the terminal is an IOS device, the current position information is obtained in the following mode:

in the IOS system, the location service control is based on a core location (CoreLocation) framework, and when positioning, a location service object (CLLocationManager), an interface of location information (CLLocationManager) and a CLLocation (a class of location information) are mainly used, where CoreLocation is a core framework of a physical location and direction, CLLocationManager is a location service control management class for obtaining information of a location, an altitude, a speed, a direction, and the like of a device, CLLocationManager is an interface for receiving location information, and CLLocation is a class of information of a latitude, a longitude, a heading, and the like reported by the system.

405. The terminal sends the current position information to a cloud server;

in this embodiment, the protocol used by the terminal to send the current location information to the cloud server may be: SUBCMD _ LOCATION _ UPDATE.

Wherein, the command word in the private protocol is used to distinguish different commands or data for transmission. In this embodiment, the terminal sends the location information to the cloud server by using a private protocol, which can improve the security of data transmission and facilitate distinguishing and transmitting the location information.

In some possible embodiments, step 405 sends the current location information to a cloud server, including:

carrying out serialization processing on the current position information;

and sending the data packet to the cloud server.

Specifically, considering that the data volume of the current position information acquired by the terminal is relatively large, some redundant data (for example, data of a plurality of search satellites before the position positioning is successful) exists in the current position information, and the cloud application needs to preferentially ensure the transmission bandwidth of the audio/video stream, if the data amount of the current location information is too large, the overall transmission bandwidth is affected, and in order to solve the technical problem, in some embodiments, the current location information sent by the terminal to the cloud server is sent in a data packet form, and the terminal needs to perform serialization processing on the current location information before sending the current location information to the cloud server, and then packaging the current position information of the terminal after the serialization processing according to a preset protocol (such as a SUBCMD _ LOCATION _ UPDATE protocol) to obtain a data packet, and finally sending the data packet to a cloud server. After receiving the data packet, the cloud server analyzes the data packet to obtain the analyzed current position information (such as longitude, latitude, altitude, azimuth, and the like). It should be understood that by performing serialization processing on the current position information, redundant data in the current position information can be removed, transmission bandwidth can be saved, and by encapsulating the current position information after serialization processing, transmission bandwidth is further reduced, so that the transmission bandwidth of audio and video streams of cloud application is ensured.

Specifically, in an actual scene, the terminal may obtain the current location information in real time, and the terminal may also obtain the current location information according to a preset time interval or a preset frequency. The terminal may send the acquired current location information to the cloud server in real time, or may send the current location information to the cloud server according to a preset time interval or a preset frequency, which is not limited herein. Since the position of the terminal may change with time, the current position information is usually a dynamic position information, and the position information at different time points may be different or the same.

In an actual application scenario, the terminal may send the current location information by using the following network protocol:

serializing current position information (Location data) and corresponding time stamps (time stamps) by adopting a protocol buffers data format, and sending the serialized current position information and the time stamps to a cloud server through a network, wherein the data format is as follows:

406. the cloud server updates the initial position information provided by the position service control into the current position information;

in this embodiment, the location service control updates the location information provided to the cloud application based on the current location information, so that the cloud application acquires the current location information of the terminal.

407. The terminal sends a closing request of the position service control to a cloud server;

in this embodiment, a protocol adopted by a request for closing a location service control sent by a terminal to a cloud server may be: SUBCMD _ GPS _ OFF _ REQ. Wherein, SUBCMD _ GPS _ OFF _ REQ refers to a request for the terminal to send GPS OFF to the cloud service.

408. The cloud server closes the position service control according to the closing request;

409. the cloud server sends closing information of the position service control to the terminal;

in this embodiment, the protocol adopted by the closing information of the location service control sent by the cloud server to the terminal may be: SUBCMD _ GPS _ OFF _ RSP.

410. And if the terminal determines that the position service control is successfully closed according to the closing information, stopping sending the position information.

In this embodiment, the cloud server side obtains the location information mainly through the cloud application service Process and the GPS hardware abstraction layer, and the cloud application service Process and the GPS hardware abstraction layer perform Inter-Process Communication (IPC) through UNIX sockets. The UNIX refers to an operating system, and domain socket is used for realizing interprocess communication.

Cloud application service process:

the device is used for monitoring the request of the terminal and forwarding the request and Location data of the terminal to the GPS hardware abstraction layer.

GPS hardware abstraction layer:

and transforming a GPS hardware abstract layer based on the UNIX domain socket to realize a GpsInterface interface. Unlike the GPS hardware abstraction layer based on real hardware devices, GPS data is not from a GPS driver, but from the cloud application service process's SUBCMD _ LOCATION _ UPDATE protocol.

The GpsInterface interface is realized as follows:

the following 4 interfaces are mainly realized:

group _ gps _ init, group _ gps _ start, group _ gps _ stop, and group _ gps _ clear.

The following describes the above 4 interfaces respectively:

closed _ gps _ init: initializing an interface, and setting a GpsCallbacks callback structure body. Creating a GPS data monitoring process GPS _ state _ thread, creating an unix socket in the GPS _ state _ thread, monitoring a command and Location data forwarded by a cloud Application service process, analyzing the Location data, then executing a corresponding callback function in the GPS callbacks, transmitting the data to a Framework layer, and obtaining the data by an Application Program Interface (API).

The GpsCallbacks callback construct is as follows:

closed _ gps _ start: opening and positioning: sending a positioning starting command to a monitoring thread GPS _ state _ thread through unix socket, updating the current state to be GPS _ STATUS _ SESSION _ BEGIN through a GPS Callbacks callback function after the monitoring thread GPS _ state _ thread monitors the command, and setting a positioning data callback function GPS _ Location _ callback.

close _ gps _ stop: closing and positioning: sending a positioning closing command to a monitoring thread GPS _ state _ thread through unix socket, after the GPS _ state _ thread monitors the command, updating the current state to be GPS _ STATUS _ SESSION _ END through a GPS _ STATUS _ callback function in a GPS callbacks structure, and setting a Location data callback function GPS _ Location _ callback function to NULL, namely, no longer reporting Location data.

clean: and clearing the gps _ state _ thread and closing the interface.

The audio circuit 906 may transmit the electrical signal obtained by converting the received audio data to the speaker 9061, and convert the electrical signal into a sound signal by the speaker 9061 and output the sound signal; on the other hand, the microphone 9062 converts the collected sound signal into an electric signal, converts the electric signal into audio data after being received by the audio circuit 906, processes the audio data by the audio data output processor 908, and then sends the audio data to, for example, another cellular phone via the RF circuit 901 or outputs the audio data to the memory 902 for further processing.

Wi-Fi belongs to short-distance wireless transmission technology, and a mobile phone can help a user to receive and send e-mails, browse webpages, access streaming media and the like through a Wi-Fi module 907, and provides wireless broadband internet access for the user. Although fig. 9 shows the Wi-Fi module 907, it is understood that it does not belong to the essential constitution of the handset, and may be omitted entirely as needed within the scope not changing the essence of the invention.
