And after the kernel is started, loading the Shell and the user application program. The application program is compiled into machine code after being started, and a process is formed.

Referring to fig. 4, in some embodiments, the system is divided into four layers, which are an Application (Applications) layer (abbreviated as "Application layer"), an Application Framework (Application Framework) layer (abbreviated as "Framework layer"), an Android runtime (Android runtime) and system library layer (abbreviated as "system runtime library layer"), and a kernel layer from top to bottom.

In some embodiments, at least one application program runs in the application program layer, and the application programs can be Window (Window) programs carried by an operating system, system setting programs, clock programs, camera applications and the like; or may be an application developed by a third party developer such as a hi program, a karaoke program, a magic mirror program, or the like. In specific implementation, the application packages in the application layer are not limited to the above examples, and may actually include other application packages, which is not limited in this embodiment of the present application.

The framework layer provides an Application Programming Interface (API) and a programming framework for the application program of the application layer. The application framework layer includes a number of predefined functions. The application framework layer acts as a processing center that decides to let the applications in the application layer act. The application program can access the resources in the system and obtain the services of the system in execution through the API interface.

As shown in fig. 4, in the embodiment of the present application, the application framework layer includes a manager (Managers), a Content Provider (Content Provider), a View System (View System), and the like, where the manager includes at least one of the following modules: an Activity Manager (Activity Manager) is used for interacting with all activities running in the system; the Location Manager (Location Manager) is used for providing the system service or application with the access of the system Location service; a Package Manager (Package Manager) for retrieving various information related to an application Package currently installed on the device; a Notification Manager (Notification Manager) for controlling display and clearing of Notification messages; a Window Manager (Window Manager) is used to manage the icons, windows, toolbars, wallpapers, and desktop components on a user interface.

In some embodiments, the activity manager is to: managing the life cycle of each application program and the general navigation backspacing function, such as controlling the exit of the application program (including switching the user interface currently displayed in the display window to the system desktop), opening, backing (including switching the user interface currently displayed in the display window to the previous user interface of the user interface currently displayed), and the like.

In some embodiments, the window manager is configured to manage all window processes, such as obtaining display size, determining whether a status bar is available, locking a screen, clipping a screen, controlling a change in a display window (e.g., reducing a display window, dithering a display, distorting a display, etc.), and so on.

In some embodiments, the system runtime layer provides support for the upper layer, i.e., the framework layer, and when the framework layer is used, the android operating system runs the C/C + + library included in the system runtime layer to implement the functions to be implemented by the framework layer.

The application may be a game, an application, or some other application associated with a computer system or other device that may be run on the smart television. The application center may obtain these applications from different sources, store them in local storage, and then be operable on the display device 200.

The above embodiments describe the hardware/software architecture and functional implementation of the display device. In some application scenarios, WIFI connection between multiple devices and a terminal in the same network is achieved through a wireless AP (i.e., a wireless access point), the wireless AP may generally be connected to a router, a switch, and other devices, and the router may allocate an IP address to a display device. As shown in fig. 6, the WIFI module 221 in the display device communicates with the wireless AP500, and specifically, the WIFI FW (WIFI Firmware, namely WIFI Firmware 221-1) in the WIFI module 221 communicates with the wireless AP 500. The communications described herein include: when the lease of the IP address allocated to the display device by the router expires, sending a lease renewal request to the wireless AP500 by the WIFI firmware 221-1 within the deadline time, receiving and responding to the lease renewal request by the wireless AP500, and if determining that the IP address can be continuously used, feeding back an ACK (acknowledgement character) to the WIFI firmware 221-1 to indicate that the receiving is correct and the lease renewal is successful; and the wireless AP500 may periodically send a Beacon packet to the WIFI firmware 221-1, where the Beacon packet is one of means for determining whether the wireless AP500 is effectively connected or not at the display device side, and if the Beacon packet is not monitored by the WIFI firmware 221-1 within a preset time, it is determined that the wireless AP500 may have been offline, where the offline may be caused by a communication failure caused by switching of a WIFI channel by a router or other abnormal factors. The communication content between the WIFI firmware 221-1 and the wireless AP500 is not limited to that described in this embodiment.

When the display device is in a standby state, for example, in an STR (Suspend to RAM) standby mode, when the display device starts the standby mode, the controller 250 may issue a standby command, the controller, each functional module, the WIFI driver 600, and the like in the display device may all enter a standby suspended state, and before the WIFI driver enters the standby suspended state, the WIFI driver generally notifies the WIFI firmware 221-1 to keep the current connection state with the router from being disconnected, and at this time, only the WIFI firmware 221-1 in the display device is in an active state, and can keep communication with the wireless AP 500.

Once the wireless AP500 switches the channel, which is equivalent to disconnecting the WIFI firmware 221-1 from the wireless AP500, so that the display device cannot renew the IP address, the router detects that the display device does not renew the IP address, and sends a disconnect packet (i.e., a disconnect packet) through the wireless AP500, but the display device is in standby, and the controller cannot process the disconnect packet, so that the WIFI driver cannot be controlled to disconnect the network connection, that is, the driving state of the WIFI driver 600 is still network connection, and the state recorded by the fact that the WIFI firmware 22-1 cannot receive the Beacon packet is network disconnection, it can be seen that the state between the WIFI firmware 22-1 and the WIFI driver 600 in standby mode is asynchronous, and thus the problem arises that when the display device is started in standby, the network connection is not disconnected, and the controller finds that the IP address is expired and unavailable, and temporarily assigns a class B IP address to the WIFI module 221, the user can see that the network is connected but in reality the user cannot get on the network at all in the display device.

In contrast, in the present application, a Beacon Timeout mechanism is added to the WIFI module 221, specifically, the WIFI firmware 221-1, and once the Beacon packet is not received within the preset time, a Beacon Timeout event is triggered, and the WIFI firmware 221-1 performs recording and subsequent reporting.

In some embodiments, the provided display device at least includes the controller 250 and the WIFI module 221, and a kernel layer of the display device has a WIFI driver, where the WIFI driver is controlled by the controller, and is used to control a network connection state of the WIFI module 221 according to a control instruction of the controller, such as disconnecting a network connection and reconnecting a network.

As shown in fig. 7, the WIFI module is in communication with the wireless access point, and configured to perform: when the display equipment is in a standby state, responding to the situation that the beacon packet sent by the wireless access point is not received within the preset time, and recording a beacon overtime event; and in response to the display device being switched from the standby state to the starting state, reporting the beacon timeout event to the controller.

A controller for performing: and responding to the received beacon timeout event, and sending a first control instruction to a WIFI driver, wherein the first control instruction is used for instructing the WIFI driver to control the WIFI module to disconnect the network connection.

The network connection state of the WIFI module is controlled by the WIFI driver program through the controller issuing a control instruction, and the WIFI driver program performs drive control, so that even if the WIFI module records a beacon timeout event, the WIFI module cannot control the WIFI module to disconnect the network connection by itself, and the WIFI module needs to be controlled by a controller on the upper layer of a system.

In the above embodiment, if the display device is in a standby state, when the router switches the channel of the WIFI, that is, the wireless access point also switches the channel, at this time, communication cannot be performed between the wireless access point and the WIFI module, and the WIFI module cannot receive the Beacon packet (that is, Beacon packet) sent by the wireless access point. When the display device side is in standby, if the WIFI module does not receive the beacon packet within the preset time, communication abnormality such as router channel switching may occur, and the WIFI records that the beacon timeout event is triggered. When the display device is started, the WIFI module reports the beacon timeout event to the controller, and in actual implementation, the WIFI module reports the beacon timeout event to the WIFI driver first, and then the WIFI driver reports the beacon timeout event to the controller. The controller responds to the received beacon timeout event and generates a first control instruction, the WIFI driver program is controlled by the first control instruction to disconnect the network connection of the WIFI module, so that the network corresponding to the IP address with the expired lease can be disconnected from the virtual connection state, a user can sense the network disconnection, the situation that the user can not surf the internet actually for the network connection is avoided, the state synchronization between the WIFI driver program and the WIFI module is realized, and in this situation, the states of the WIFI driver program and the WIFI module are not connected with each other.

When the network in the display device is connected in a virtual mode, the control in the WIFI connection can still be displayed in the display device, and a user can see that the network is not disconnected and can see the temporarily allocated B-type IP address of the network in a network connection/setting interface, so that the current network is considered to be connected and cannot timely sense that the current network is really disconnected. Only when the network is subsequently accessed, the network connection is found to be unavailable, and the network is manually logged in again. In the above embodiment, when the display device is switched from standby to startup, it may be directly shown to the user that the network is not connected, for example, a control that the network is not connected is displayed on the interface, or a prompt message that the network is not connected is displayed, so that the user can really and accurately perceive that the display device is not networked, thereby logging in the network again more quickly and timely.

In the above embodiment, the controller sends the first control instruction, and finally controls the WIFI module to disconnect the network connection, which requires the user to log in the network again manually, that is, manually connect the network. To further enhance the user experience, in some embodiments, as shown in fig. 7, the controller 250 is further configured to: after the first control instruction is sent to the WIFI driver, a second control instruction is sent to the WIFI driver, and the second control instruction is used for indicating the WIFI driver to control the WIFI module to reconnect the network after the network connection is disconnected, and updating the WIFI information recorded by the WIFI module.

Namely, the controller firstly sends a first control instruction to disconnect the virtual network corresponding to the time when the IP address lease is due and is not renewed and/or the WIFI channel is changed; and then continuously sending a second control instruction to reconnect the network, wherein the newly connected network can have the IP address newly allocated by the router and is matched with the updated channel, so that the user can normally use the network. In this embodiment, the program of disconnecting and reconnecting the network may be continuously executed, and the WIFI information may be updated, where the WIFI information includes: the WIFI information may also include information such as a router MAC address, a router IP address, a WIFI name, a subnet mask, and the like, which is specifically subject to actual application.

In this embodiment, if the display device is in a standby state, when the router switches the channel of the WIFI, that is, the wireless access point also switches the channel, at this time, communication cannot be performed between the wireless access point and the WIFI module, and the WIFI module cannot receive the Beacon packet (that is, Beacon packet) sent by the wireless access point. When the display device side is in standby, if the WIFI module does not receive the beacon packet within the preset time, the situation that the router switches channels may occur, and the WIFI records that the beacon overtime event is triggered. When the display equipment is started, the beacon timeout event is reported to the controller, so that the controller generates a first control instruction, the first control instruction enables the WIFI driver to control the WIFI module to disconnect and then reconnect the network, namely, the network connection is disconnected firstly, the network corresponding to the IP address with the lease due is disconnected from the virtual connection state, then the network is reconnected under the control of a second control instruction, the reconnected network can use the IP address newly distributed by the router and the latest channel, the network connection is guaranteed to be effective, WIFI information is updated, state synchronization between the WIFI driver and the WIFI module is achieved, and after the network connection is conducted again, the states of the WIFI driver and the WIFI module are all network connections. Under the condition, the network can be automatically reconnected when the display equipment is started, the user can not perceive the condition of network disconnection, the user can surf the internet normally without manually logging in the network connection, and the user experience is improved.

In some embodiments, as shown in fig. 8, the controller is configured to perform: and responding to the received beacon timeout event, and sending a control instruction to a WIFI driver, wherein the control instruction is used for instructing the WIFI driver to control the WIFI module to reconnect the network after disconnection, and updating WIFI information recorded by the WIFI module.

The mode is equivalent to combining the first control instruction and the second control instruction in the embodiment to obtain one control instruction, so that the controller is not required to continuously send two control instructions, but a single control instruction directly instructs the WIFI driver to start the equipment to be reconnected after the control network is disconnected, the network connection can be automatically completed when the equipment is started, a user does not need to sense that the equipment is disconnected and manually reconnects the network, the user experience is improved, the times of instruction generation, sending and response can be reduced, the network connection efficiency after the equipment is started is improved, and the accuracy of WIFI connection is high.

Therefore, according to the scheme of each embodiment of the application, even if the controller cannot process the disconnection packet, namely the disconnection packet cannot take effect, the beacon timeout event can be reported when the device is started, so that the display device can actively disconnect the network or disconnect and reconnect the network, the problem of network connection when the display device is started from standby is solved, the network state between the WIFI driver and the WIFI firmware is kept synchronous, and the channel uniformity of the display device and the router is ensured.

In the above embodiments, if the WIFI firmware can always receive the Beacon packet sent by the wireless AP regularly in the standby process, that is, the Beacon timeout event is not triggered, it indicates that the WIFI firmware and the wireless AP always maintain effective communication, and can renew lease when the lease of the IP address expires, the display device maintains the network connection state in the standby state after being started, and the user can use the network normally.

The scheme is not only suitable for a router to switch a WIFI channel, but also suitable for other situations which cause communication failure between WIFI firmware and a wireless AP, and as long as a beacon timeout event is triggered when equipment is in standby, namely the network connection is considered to be abnormal, the network connection can be disconnected when the equipment is in standby to start, or the network is reconnected after disconnection, so that the scheme can be suitable for wide application scenes, is low in scheme coupling degree and has good platform portability. The network connection and the application of the display device, such as a Dynamic Host Configuration Protocol (DHCP), may be implemented between the display device and the router according to a related network Protocol, which is not described in detail herein.
