As shown in fig. 3, in some embodiments, the hierarchical architecture of the electronic device divides the software into several layers, each with a clear role and division of work. The layers communicate with each other through a software interface. In some embodiments, the ANDROID (ANDROID) system is divided into four layers, from top to bottom, an application layer, an application framework layer, a radio interface layer (Radio Layer Interface, RIL), and a Modem processor (Modem) layer, respectively.

For the electronic device in fig. 3, data interaction between the application layer and the application framework layer can be performed through a conventional interface; the application framework layer and the RIL can interact data through a hardware abstraction layer interface definition language (Hardware Abstraction Layer Interface Definition Language, HIDL) interface, and the RIL and the Modem can interact data based on the chip architecture of the electronic device. For example, the RIL and Modem interact data by way of PCI-Express (peripheral component interconnect Express, PCIE) or memory sharing.

The application layer may include aA series of applications. As shown in fig. 3, the application package may include: gallery, text messaging, navigation, bluetooth, and video applications 3001. The video application 3001 may play video stored at a remote server in the case where the electronic device is connected to a network. In the case that the connection between the electronic device and the network is disconnected, the video application 3001 pops up a no-network prompt on the display interface corresponding to the video application 3001. Video applications, for example short video social applications, such as Application, & gt>Application, etc.

The application framework layer provides an application programming interface (Application Programming Interface, API) and programming framework for application programs of the application layer. The application framework layer includes a number of predefined functions. As shown in fig. 3, the application framework layer may include a Telephony manager (Telephony) 3002 and a connectivity service (connectivity service) 3003.

The phone manager 3002 is used to provide management functions for cellular related services of the electronic device. For example, the phone manager 3002 is used to provide management of call status (including on, and hang-up, etc.) and cellular data connection status (including established connection with the cellular data network, disconnected from the cellular data network, being connected to the cellular data network, being disconnected from the cellular data network, etc.). The connection service 3003 is used to manage the manner in which the electronic device uses data traffic. The manner in which the electronic device uses the data services may include the electronic device using the data services over a cellular data network, or Wi-Fi, or hot spot, or a network cable, etc. The connection service 3003 may receive the change information and notify the change information by acquiring interfaces of other services. The connection service 3003 knows the cellular data connection status through the phone manager 3002. After learning the cellular data connection status, the connection service 3003 may notify the application layer of the cellular data connection status, such as to the video application 3001. The cellular data network may include a 2G network, a 3G network, a 4G network, a 5G network, a future wireless communication network, and the like.

In a possible implementation manner, the application framework layer may further include: window manager, notification manager, content manager, view system, resource manager, etc. (not shown in fig. 3), which is not limiting in this embodiment of the application.

The window manager is used for managing window programs. The window manager may obtain the display screen size, determine if there is a status bar, lock the screen, touch the screen, drag the screen, intercept the screen, etc. The notification manager allows the application to display notification information in a status bar, can be used to communicate notification type messages, can automatically disappear after a short dwell, and does not require user interaction. Such as notification manager is used to inform that the download is complete, message alerts, etc. The content provider is used to store and retrieve data and make such data accessible to applications. The data may include video, images, audio, calls made and received, browsing history and bookmarks, phonebooks, etc. The view system includes visual controls, such as controls to display text, controls to display pictures, and the like. The view system may be used to build applications. The display interface may be composed of one or more views. For example, a display interface including a text message notification icon may include a view displaying text and a view displaying a picture. The resource manager provides various resources for the application program, such as localization strings, icons, pictures, layout files, video files, and the like.

RIL is the interface layer between application program frame layer and Modem module, responsible for the transmission of the operation of the relevant business control plane of cellular, responsible for the reliable transmission of data. A radio interface layer daemon (Radio Interface Layer Daemon, rild) may be included in the RIL, which rild may include: ril service module 3004. For example, the ril service module 3004 may be configured to forward the SIM instruction sent by the phone manager 3002 via the HIDL interface to the Modem module, and forward the response data corresponding to the SIM instruction returned by the Modem module, and the state or notification actively reported by the Modem module to the phone manager 3002.

The Modem module comprises: protocol stack and card processing module. The protocol stacks may include wireless communication protocol stacks such as 2G protocol stacks, 3G protocol stacks, 4G protocol stacks, and 5G protocol stacks.

The card processing module may comprise a related module of the SIM card. Such as a SIM card module, a local SIM card module, a SIM card slot driver, etc. The SIM card slot driver can be connected with a SIM hard card.

A SIM card module: for providing network registration, authentication, etc. functions related to SIM information. The SIM card module can support a local SIM card calling mode provided by the local SIM card module.

Local SIM card module: for enabling access to local SIM card information using a SIM card slot driver.

In a possible implementation manner, a SIM card slot driver and a SIM hard card may be disposed in a Modem of the electronic device; alternatively, the SIM card slot driver and the SIM hard card may not be provided in the Modem of the electronic device, and the electronic device may use the local eSIM.

The above-described exemplary architecture diagram of the ANDROID system is merely illustrative, and is not meant to be limiting. It should be noted that although the embodiment of the present application is described by taking the ANDROID system as an example, the basic principle is equally applicable to the iOS-based system ^TM Or WINDOWS ^TM And the like operating the electronic device of the system.

Fig. 4 is a state machine responsible for maintaining cellular data connection status provided by an embodiment of the present application. The state machine is a data connection (DataConnection, DC) module in the telephony manager 3002 that can be used to effect handoff of the cellular data connection state.

As shown in fig. 4, the State machine includes four states: a data connection default state (may be abbreviated as DcDefaultState), a data connection inactive state (may be abbreviated as dcinactive state), a data connection active state (may be abbreviated as dcactivative state), and a data connection activated state (may be abbreviated as dcactivative state).

Four states in the state machine are first described.

The DcDefaultState state represents the state at the time of creation of the state machine, which is not initialized at this time. After the state machine is initialized, the state machine enters a DcInacteState state from the DcDefaultState state.

The dcinactive state indicates that the current electronic device is not establishing a connection with the cellular data network. In the dcinactive state, the state machine may attempt to establish a connection with the cellular data network. The state machine attempts to establish a connection with the cellular data network while switching state from the dcinactive state to the dcactive state.

The DcActivatingState indicates that the electronic device is establishing a connection with the cellular data network. In the dcactivating state, the state machine may generate a data call instruction to control the Modem to perform a data call action to establish a connection with the cellular data network. If the Modem and RIL return data call result in failure to establish connection with the cellular data network, the state opportunity switches from DcActivate State state back to DcInactive State state. If the data call is successfully established between the Modem and the RIL, the state machine switches the state from the DcActivate state to the DcActivate state.

The DcActivateState state indicates that the connection with the cellular data network was established successfully. And then the necessary link configuration, route configuration and the like are completed in the application program framework layer, so that networking service can be provided for the application in the application program layer.

As shown in fig. 4, the operating logic of the state machine is as follows:

401, initializing a state machine, and switching from a DcDefaultState state to a DcInacteState state.

For example, when a user opens a cellular data switch, the application layer generates a data call command and sends the generated data call command to the state machine to establish a cellular data connection. For another example, if an electronic device opens a cellular data switch and is in a WiFi connection state, after the electronic device disconnects the WiFi connection, the application framework layer of the electronic device generates a data call command and sends the generated data call command to a state machine to establish the cellular data connection. The data call command is used to trigger an action of the state machine to establish a connection with the cellular data network. When the state machine receives a data call command sent by the application layer or application framework layer, the state machine triggers an action to establish a connection with the cellular data network, attempting to establish a connection with the cellular data network.

The data call command may include a connection parameter (ConnectionParameters, CP). The connection parameters are used to enable connection establishment with the cellular data network. The connection parameters may include an authentication parameter (creatals), a maximum channel number (channel_max), and the like.

If the state machine receives a data call command, the state machine stores connection parameters in the data call command 402. After receiving the data call command, the state machine switches from the dcinactive state to the dcactive state.

In conventional techniques, when an event triggers an application layer or an application framework layer to generate a data call command, the application layer or the application framework layer generates the data call command in response to the event. Therefore, there is no need to store the connection parameters in each generated data call command.

In the present application, after the application layer or the application framework layer generates the data call command, the data call command may be sent to the state machine, and then the state machine may store the connection parameters in the data call command, so as to generate the data call command again according to the stored connection parameters in the data call command after detecting the data call disconnection event. That is, it is not necessary for the application layer or the application framework layer to generate a data call command and transmit the generated data call command to the state machine when the data call disconnection event is detected later.

403, the state machine generates a data call instruction according to the connection parameters in the data call command. The data call instruction is used for controlling the Modem module to execute data call actions and establish connection with the cellular data network.

For example, the state machine may send a data call instruction to ril service module 3004, and ril service module 3004 may send a received data call instruction to the Modem module. After receiving the data call instruction, the Modem module executes a data call action corresponding to the data call instruction. Specifically, the state machine may encapsulate the data call instruction according to the RIL format, and send the data call instruction to the RIL service module 3004.

The state machine determines 404 whether the data call was successful.

If the data call fails, the state machine switches from the DcActivateState state back to the DcInactyState state. If the data call is successful, the state machine is switched from the DcActivate State state to the DcActivate State state.

After the Modem module performs the data call action corresponding to the data call instruction, the data call result corresponding to the data call action is sent to the ril service module 3004, and the ril service module 3004 sends the received data call result to the state machine. And the state machine determines whether the data call is successful or not according to the data call result returned by the Modem module and the RIL. The data call results may include a domain name system (Domain Name System, DNS) address, an internet protocol (Internet Protocol, IP) address, etc.

After the state machine enters the DcActivateState state, the application framework layer completes the necessary configuration (such as link configuration, routing configuration and the like) of the application networking in the application layer, and provides networking services for the application in the application layer.

After the state machine switches to the DcActivateState state, if a data call disconnection event is detected, the state machine executes 405, i.e., switches from the DcActivateState to the DcActivatingState state according to the detected data call disconnection event. When the state machine switches back to the dcactivating state, 403 is re-executed. When the state machine is in DcActivate state, the state machine generates a data call instruction again according to the connection parameters in the data call instruction, and sends the data call instruction to the Modem module.

The data call disconnect event is used to indicate that the current electronic device is not connected to the cellular data network. In some embodiments of the application, the Modem module detects a data call disconnect event and notifies the RIL of the data call disconnect event, which notifies the state machine of the received data call disconnect event.

After the state machine returns to the DcActivate state, a data call instruction is regenerated according to the stored connection parameters, so that the Modem module executes the data call action.

It will be appreciated that after re-execution 403, the state machine continues to execute 404, and the state machine determines whether the data call was successful.

If it is determined that the data call fails, the state machine switches from the dcactivating state back to the dcinactive state and notifies the application layer of a data call disconnect event. The state machine resides in the telephony manager 3002 in the application framework layer. Illustratively, the state machine may notify the connection service 3003 of a data call disconnect event through the telephony manager 3002. The data call disconnect event is notified by the connection service 3003 to an application in the application layer, such as to a video application in the application layer. Some video applications may preset hint rules. After detecting the data call disconnection event notified by the connection service 3003, the video application pops up a prompt box according to a preset prompt rule. The prompt box is used for prompting the user that the current video application has no network connection, for example, displaying 'current no network, please retry after detection'.

If the data call is determined to be successful, the state machine is switched from the DcActivate State state to the DcActivate State state. It will be appreciated that if it is determined that the data call is successful, the state machine will not notify the application layer of the data call disconnect event, which may be intercepted. That is, the state machine does not notify the connection service 3003 of the data call disconnection event through the phone manager 3002. The application program in the application program layer does not sense the data call disconnection event, so the application program does not generate a prompt for the data call disconnection event, namely, the no-network prompt is not popped up, and the number of times of popping up the no-network prompt is reduced.

In some embodiments of the present application, the state machine performs 405 a switch from the DcActivateState state back to the DcActivatingState state according to the detected data call disconnect event, which may specifically include:

if a data call disconnection event is detected, the state machine acquires a reason value corresponding to the data call disconnection event; and when the cause value is not the preset target cause value, the state machine is switched back to the DcActivate state from the DcActivate state.

After the state machine switches back to the dcactivating state, the state machine re-establishes the data call, i.e. re-executes 403, according to the connection parameters.

In some embodiments of the present application, when the cause value is a preset target cause value, the state machine switches from the DcActivateState state to the dcinactive state. After the state machine switches back to the dcinactive state, the application layer will be notified of the data call disconnect event.

In an embodiment of the present application, one or more target cause values may be preset according to a situation in which a data call cannot be re-established. For example, the target cause value may include: 0x08 (operator_barred, OPERATOR forbidden); 0x1B (missing_unknown_apn, UNKNOWN or invalid APN); 0x1D (user_authentication, AUTHENTICATION failure); 0x6F (protocol_error), PROTOCOL error; -5 (radio_power_off, modem powered down); 0x10001 (radio_not_available, modem is NOT AVAILABLE); 0x10002 (unacceptable_network_parameter), UNACCEPTABLE NETWORK errors. It will be appreciated that the above target cause values are merely illustrative and not limiting in any way.

By presetting the target cause value, only the data call disconnection event which does not carry the target cause value is reestablished, the number of times of data reestablishment on the data call disconnection event which cannot be reestablished can be reduced, the energy loss can be reduced, and a quick response can be given for the specific situation corresponding to the target cause value so as to remind the user that the network is disconnected in time.

In other embodiments of the present application, the state machine switches from the DcActivateState state back to the DcActivatingState state when the cause value is a preset specific cause value. After the state machine switches back to the dcactivating state, the state machine re-establishes the data call, i.e. re-executes 403, according to the connection parameters.

In embodiments of the present application, one or more specific cause values may be preset according to the situation in which a data call can be re-established. When the cause value is a preset specific cause value, determining that the state machine can reestablish the data call according to the stored connection parameters. The specific cause value may be set according to the actual situation, and is not limited in any way.

And when the cause value is not the preset specific cause value, the state machine is switched back to the DcInactive state from the DcActivatestate. After the state machine switches back to the dcinactive state, the application layer will be notified of the data call disconnect event. That is, when the cause value is not a preset specific cause value, the state machine does not reestablish the call.

By presetting the specific cause value, only the data call disconnection event carrying the specific cause value is reestablished, the number of times of data reestablishment on the data disconnection event which cannot reestablish the data call can be reduced, the energy loss can be reduced, and a quick response can be given for the specific situation corresponding to the non-specific cause value so as to remind the user that the network is disconnected in time. According to the state machine provided by the embodiment, after the data call disconnection event is detected, the data call is reestablished according to the connection parameters after the data call disconnection event is switched from the DcActivateState state to the DcActivatestate, if the data call is reestablished successfully, the data call disconnection event can not be notified to the application program layer, so that the application program in the application program layer does not feel the data call disconnection event, and the application program is prevented from generating a network-free prompt according to the data call disconnection event.

The state machine includes, in addition to the states in fig. 4, a dcdisconnectionstate, e.g., a state machine responsible for maintaining cellular data connection states as shown in fig. 5.

The DcDisconnectingState state indicates that the electronic device is automatically disconnecting from the cell, e.g., indicates that the application framework layer and the levels above it are automatically disconnecting from the cell. After the electronic device is completely disconnected from the cellular connection, the state machine switches from the dcdisconnectionstate state back to the dcinactive state.

As shown in FIG. 5, the state machine has operating logic comprising 501-507, wherein 501-505 are the same as 401-405 in FIG. 4 and are not described in detail herein. The state machine's operating logic further includes:

the state machine detects an automatic disconnect event 506 and switches from the DcActivateState state to the DcDisconnectingState state.

When the state machine is in the DcActivateState state, if an event that the electronic equipment actively disconnects the cellular connection (such as a cell switch to a Wi-Fi event and a user closes a mobile data switch event) is detected, the state machine is switched from the DcActivateState to the DcDisconnectingState.

507, the state machine determines that the cellular connection has been broken, and the state machine enters from the dcdisconnectionstate state to the dcinactive state. It will be appreciated that the state machine, upon entering the dcinactive state, will notify the application layer of a data call disconnect event. The notification procedure of the data call disconnection event is as described above and will not be described in detail herein. And after the application program in the application program layer detects the data call disconnection event, displaying the network-free prompt according to a preset rule.

Fig. 6 is a schematic diagram of a data communication method according to an embodiment of the present application, where the method is applied to an electronic device, and the electronic device includes an application program, a connection service, a phone manager, an RIL, and a Modem. As shown in fig. 6, the method may include:

In step S601, when the phone manager receives the data call command, the connection parameters in the data call command are stored.

The application layer or application framework layer may send a data call command to the telephony manager.

In step S602, the phone manager generates a data call instruction based on the connection parameters in the data call command.

In step S603, the phone manager sends a data call instruction to the RIL.

In step S604, the RIL sends a data call instruction to the Modem module.

In step S605, the Modem module executes a data call action corresponding to the data call instruction.

In step S606, the Modem module sends the data call result to the RIL.

In step S607, RIL sends the data call results to the telephony manager.

In step S608, the telephony manager determines whether the data call was successful. The telephony manager determines whether the data call was successful based on the data call results sent by the RIL.

If the data call fails, the process ends.

If the data call is successful, step S609 is performed.

In step S609, if the phone manager detects a data call disconnection event, the phone manager regenerates the data call instruction according to the connection parameters stored in S601.

In step S610, the phone manager sends a data call instruction to the RIL.

In step S611, the RIL sends a data call instruction to the Modem module.

In step S612, the Modem module executes a data call action corresponding to the data call instruction.

In step S613, the Modem module sends the data call result to the RIL.

In step S614, the RIL sends the data call results to the telephony manager.

In step S615, the telephony manager determines whether the data call was successful.

If the data call is successful, the telephony manager does not notify the application layer of the data call disconnect event. Accordingly, the application program will not generate a prompt for the event of disconnection of the data call, i.e. will not pop up a prompt without network, and the flow ends.

If the data call fails, step S616 is performed.

In step S616, the telephony manager notifies the connection service of a data call disconnect event.

In step S617, the connection service notifies the application of a data call disconnection event. The application program may comprise a video application.

In step S618, the application program displays the no-network prompt corresponding to the data call disconnection event.

Some embodiments of steps S601-618 can be seen in the related description of fig. 4, and will not be described here.

It will be appreciated that after step S615 is performed, the phone manager determines that the data call is successful, if a data call disconnection event is detected again, step S609 may be performed again, that is, after the data call disconnection event is detected again, the data call instruction is regenerated again according to the connection parameters, and the data call is established.

According to the data communication method provided by the embodiment, after the electronic equipment establishes the data call successfully, the data call can be actively reestablished based on the connection parameters when the data call is established when the data call disconnection event is detected, if the data call is reestablished successfully, the data call disconnection event can not be notified to the application program layer, so that the application program in the application program layer does not feel the data call disconnection event, and the application program is prevented from generating a network-free prompt according to the data call disconnection event, thereby effectively reducing the network-free prompt.
