The electronic device 100 interacts with the network through the SIM card to implement functions such as communication and data communication. In some embodiments, the electronic device 100 employs esims, namely: an embedded SIM card. The eSIM card can be embedded in the electronic device 100 and cannot be separated from the electronic device 100.

It is to be understood that the illustrated structure of the embodiment of the present application does not specifically limit the electronic device 100. In other embodiments of the present application, electronic device 100 may include more or fewer components than shown, or some components may be combined, some components may be split, or a different arrangement of components. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

Fig. 2 is a schematic system architecture diagram of the electronic device 100 according to an embodiment of the present disclosure.

It will be appreciated that the layered architecture of the electronic device divides the software into several layers, each layer having a clear role and division of labor. The layers communicate with each other through a software interface. In some embodiments, an android system is divided into four layers, which are an application Layer, an application framework Layer, a Radio Interface Layer (RIL), and a Modem processor (Modem) Layer from top to bottom.

For the electronic device 100 in fig. 2, data interaction between the application layer and the application framework layer can be performed through a conventional interface. Data interaction between the application framework Layer and the RIL can be carried out through a Hardware Abstraction Layer Interface Definition Language (HIDL) Interface. The RIL and the Modem layer can perform data interaction based on a chip architecture of the electronic equipment. For example, the RIL and the Modem layer perform data interaction by means of PCI Express (peripheral component interconnect Express, PCIE) or memory sharing.

The application layer may include a series of applications. Applications may include, but are not limited to, gallery, sms, navigation, bluetooth, and video applications, among others.

The Application 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. As shown in fig. 2, the application framework layer may include a Telephony manager (Telephony) and a connectivity service (connectitvievice).

Wherein the phone manager is configured to provide management functions for cellular related services of the electronic device 100. For example, a phone manager is used to provide management of call states (including on, off, etc.) and cellular data connection states (including connected to, disconnected from, establishing, disconnecting from, etc.) a cellular network.

The connectivity service is used to manage the manner in which data traffic is used by the electronic device 100. The manner in which the electronic device 100 uses the data service may include the electronic device using the data service through a cellular network, or Wi-Fi, or a network cable, etc. The connection service may receive change information and notify the change information by acquiring an interface of the other service. The connection service learns the cellular data connection status through the phone manager. The connection service may display or hide the identity of the cellular data traffic (e.g., identity 301 shown in fig. 3) after knowing the cellular data connection status. Specifically, after knowing that the cellular data connection status is established, the connection service displays an identifier of the cellular data service, thereby prompting the user to: the electronic device is already connected to the cellular network and the application is using or preparing to use the cellular data. After knowing that the cellular data connection state is disconnected, the connection service hides the identifier of the cellular data service, thereby prompting the user to: the electronic device is not connected to the cellular network and the application does not use cellular data. It is understood that cellular networks may include 2G networks, 3G networks, 4G networks, and 5G networks (e.g., SA networks), among others.

In a possible implementation manner, the application framework layer may further include: a window manager, a notification manager, a content manager, a view system, and a resource manager (not shown in fig. 2), which are not limited in this embodiment of the present application.

Wherein, the window manager is used for managing the window program. The window manager can obtain the size of the display screen, judge whether a status bar exists, lock the screen, touch the screen, drag the screen, intercept the screen and the like. The notification manager enables the application to display notification information in the status bar, can be used to convey notification-type messages, can disappear automatically after a short dwell, and does not require user interaction. Such as a notification manager used to inform download completion, message alerts, etc. The content provider is used to store and retrieve data and make it accessible to applications. The data may include video, images, audio, calls made and answered, browsing history and bookmarks, phone books, 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, the display interface including the short message notification icon may include a view for displaying text and a view for displaying pictures. The resource manager provides various resources for the application, such as localized strings, icons, pictures, layout files, video files, and the like.

The RIL is an interface layer between the application framework layer and the Modem layer, and is responsible for the transmission of the operation of the control plane of the cellular related service and the reliable transmission of data. The RIL may include a Radio Interface Layer Daemon (rild), and the rild may include: ril service module. For example, the ril service module may be configured to forward the SIM command sent by the telephony manager via the HIDL interface to the Modem layer, and forward response data corresponding to the SIM command returned by the Modem layer and a status or notification actively reported by the Modem layer to the telephony manager.

The Modem layer includes a modulation and demodulation processor (Modem), and the Modem may include: protocol stack and card processing module. The protocol stack can include 2G protocol stack, 3G protocol stack, 4G protocol stack, 5G protocol stack and other wireless communication protocol stacks.

The card processing module may include a module associated with the SIM card. Such as a SIM card module, a local SIM card module, and a SIM card slot driver, etc. Wherein, the SIM card slot driver can be connected with an SIM hard card.

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

Local SIM card module: the SIM card slot driver is used for realizing the access to the local SIM card information.

In a possible implementation manner, a SIM card slot driver and a SIM hard card may be disposed in the Modem of the electronic device 100; alternatively, the SIM card slot driver and the SIM card may not be provided in the Modem of the electronic device 100, and the electronic device 100 may use a local eSIM at this time.

The above schematic diagram of the android system architecture is merely illustrative and not limiting. Although the embodiment of the present application is described by taking the android system as an example, the basic principle is also applied to the iOS-based system ^TM Or WINDOWS ^TM And the like operating the system.

It will be appreciated that when electronic device 100 switches from Wi-Fi to SA network, the cellular data service needs to be activated and a PDU session established. When the electronic device 100 is switched from the SA network to the Wi-Fi, the cellular data service needs to be deactivated, and the PDU session is released.

An application scenario of the embodiment of the present application is described below by taking an example that when the electronic device 100 is in an SA network and is switched from the SA network to Wi-Fi, the cellular data service needs to be deactivated, and a PDU session is established.

Fig. 4 is a schematic diagram of an information interaction scenario in which electronic device 100 deactivates cellular data services. When the electronic device 100 is connected to the SA network first and then to the Wi-Fi network, the electronic device 100 switches from the SA network to the Wi-Fi network, and the SA network is disconnected. At this point, the electronic device 100 needs to deactivate the cellular data service and release the PDU session.

Specifically, as shown in fig. 4, the electronic apparatus 100 includes a connection service, a telephone manager, an RIL, and a Modem. First, the electronic apparatus 100 transmits a release network Request (ReleaseNetwork Request) message for requesting termination of a cellular data connection to the phone manager through the connection service (see step S401).

After receiving the release network request message through the phone manager, the electronic device 100 sends a Deactivate Data call request (Deactivate Data call request) message (see step S402) to the RIL, where the Deactivate Data call request message (i.e., the first message) is used to request deactivation of the cellular Data service.

After receiving the deactivation data call request Message through the RIL, the electronic device 100 sends the deactivation data call request Message to the Modem through a high-pass information Interface (QMI) or an AT command (AT command) (see step S403). The AT command is a unified Modem command standard.

After receiving the data call deactivation request message through the Modem, the electronic device 100 sends a release PDU session request (ReleasePDU sessionRequest) message to the network device (e.g., the base station) (see step S404), where the release PDU session request message (i.e., the second message) is used to request release of the PDU session.

The network device releases the PDU session in response to the release PDU session request message (see step S405), thereby terminating the cellular data connection.

Then, the network device sends a Release PDU session complete (Release PDU session complete) message to the Modem of the electronic device 100 (see step S406), where the Release PDU session complete message is used to notify the Modem of the electronic device 100 that the network side has released the PDU session.

After receiving the PDU release session complete message through the Modem, the electronic device 100 sends a Data call response (deactivated Data call response) message to the RIL (see step S407), where the Data call response message is used to notify the RIL that the network side has deactivated the cellular Data service.

After receiving the deactivation data call response message through the RIL, the electronic device 100 transmits a deactivation data call response message to the phone manager (see step S408).

After receiving the data call deactivation response message through the phone manager, the electronic device 100 sends a Release network response (Release network response) message to the connection service (see step S409), where the Release network response message is used to notify the connection service that the network side has terminated the cellular data connection.

After the electronic device 100 receives the release network response message through the connection service, the network card driver of the cellular data service is removed or disabled (see step S410), and the deactivation of the cellular data service is completed.

It will be appreciated that during deactivation or activation of cellular data services by electronic device 100, a network connection failure problem may occur. If the electronic device 100 frequently deactivates or activates the cellular data service, the PDU session is frequently released or established, which results in an increased probability of network connection failure and may cause a larger signaling overhead, resulting in a larger service delay.

In view of this, embodiments of the present application provide a data communication method, which maintains a PDU session without deactivating a cellular data service after the cellular data service is activated for the first time. In the network switching process, the cellular data service does not need to be frequently deactivated or activated, so that the probability of network connection failure can be reduced, and the service delay is reduced.

Specifically, when electronic device 100 switches from the SA network to Wi-Fi, the PDU session is maintained and the application preferentially uses Wi-Fi, hiding the identity of the cellular data service, thereby prompting the user to: the application does not use the cellular data. Alternatively, the application uses both Wi-Fi and cellular data to display an identification of cellular data services, thereby prompting the user to: the application is using or preparing to use the cellular data. When the electronic device 100 switches from Wi-Fi to SA network, the PDU session does not need to be established again, displaying the identity of the cellular data service. In the network switching process, the user can know the cellular data connection state by looking up the identification of the cellular data service, and does not perceive that the cellular data service is not deactivated.

The following specifically describes the data communication method provided in the embodiments of the present application, taking embodiments 1 to 3 as examples.

It should be noted that the data communication method provided in the embodiment of the present application is applied to the electronic device 100. The electronic device 100 includes a connection service, a phone manager, a RIL, and a Modem.

In addition, for convenience of description, embodiments 1 to 3 each take as an example a scenario in which the electronic device 100 is in an SA network and switches from the SA network to Wi-Fi.

Example 1

Fig. 5 is a schematic view of an information interaction scenario of the data communication method provided in embodiment 1.

As shown in fig. 5, the data communication method may include the steps of:

s501, sending a Release Network Request (Release Network Request) message to the phone manager through the connection service.

Wherein the release network request message is for requesting suspension of the cellular data connection. Suspending the cellular data connection refers to deactivating the cellular data without disconnecting the cellular data connection.

S502, after receiving the network release Request message through the phone manager, the Call manager does not send a Data Call deactivation Request (deactivation Data Call Request) message to the RIL.

It will be appreciated that the Data communication method shown in fig. 5 does not Deactivate the cellular Data service by intercepting the Deactivate Data Call Request message in step S402 shown in fig. 4. Specifically, when the electronic device 100 is switched from the SA network to the Wi-Fi network, the deactivation data call request message is intercepted without sending the deactivation data call request message to the RIL through the phone manager, so that the PDU session can be maintained, the cellular data service is not deactivated, the probability of network connection failure can be reduced, and the service delay can be reduced.

Example 2

Fig. 6 is a schematic view of an information interaction scenario of the data communication method provided in embodiment 2.

As shown in fig. 6, the data communication method may include the steps of:

s601, sending a Release Network Request (Release Network Request) message to the phone manager through the connection service.

It is understood that step S601 is the same as step S501 shown in fig. 5, and is not described here again.

S602, after receiving the network release Request message through the phone manager, sending a Data Call Request (Deactivate Data Call Request) message to the RIL.

Wherein the deactivate data call request message (i.e., the first message) is used to request deactivation of the cellular data service.

S603, after receiving the data call deactivation request message through the RIL, the RIL does not send the data call deactivation request message to the Modem.

It is to be understood that the Data communication method shown in fig. 6 does not Deactivate the cellular Data service by intercepting the Deactivate Data Call Request message in step S403 shown in fig. 4. Specifically, when the electronic device 100 is switched from the SA network to the Wi-Fi network, the deactivation data call request message is not sent to the Modem through the RIL, that is, the deactivation data call request message is intercepted, so that the PDU session can be maintained, the cellular data service is not deactivated, the probability of network connection failure can be reduced, and the service delay can be reduced.

Example 3

Fig. 7 is a schematic view of an information interaction scenario of the data communication method provided in embodiment 3.

As shown in fig. 7, the data communication method may include the steps of:

s701, sending a Release Network Request (Release Network Request) message to the phone manager through the connection service.

S702, after receiving the network release Request message through the phone manager, sends a Data Call Request (Deactivate Data Call Request) message to the RIL.

It is understood that steps S701 to S702 are the same as steps S601 to S602 shown in fig. 6, and are not described herein again.

S703, after receiving the data call deactivation request message through the RIL, sends the data call deactivation request message to the Modem through the QMI or AT instruction.

S704, after receiving the data call deactivation Request message through the Modem, does not send a Release PDU session Request (Release PDU session Request) message to the network device.

Wherein the release PDU session request message (i.e., the second message) is for requesting release of the PDU session.

It can be understood that the data communication method shown in fig. 7 does not deactivate the cellular data service by blocking the Release PDU session Request message (Release PDU session Request) in step S404 shown in fig. 4. Specifically, when the electronic device 100 is switched from the SA network to the Wi-Fi network, the PDU session release request message is intercepted without sending the PDU session release request message to the network device through the Modem, so that the PDU session can be maintained, the cellular data service is not deactivated, the probability of network connection failure can be reduced, and the service delay can be reduced.

In some embodiments, after the electronic device 100 performs any one of embodiments 1 to 3, the data communication method may further include: concealing the identity of the cellular data service.

It is appreciated that as shown in fig. 8, when electronic device 100 does not deactivate cellular data services, electronic device 100 may hide the identity of the cellular data services (e.g., 301 shown in fig. 3), thereby prompting the user to: the application does not use the cellular data.

In other embodiments, when the electronic device 100 uses a one-touch login function provided by an operator or uses a cellular data service for Network acceleration, an application calls a Request Network (Request Network) interface, and the data communication method provided by the embodiment of the present application may prompt a user by displaying an identifier (301 shown in fig. 3) of the cellular data service: the application is using or preparing to use the cellular data. Wherein the requesting network interface is for requesting cellular data services. Then, when the electronic device 100 stops using the one-touch login function provided by the operator or stops using the cellular data service to perform Network acceleration, the application calls a Release Network (Release Network) interface, and the data communication method provided in the embodiment of the present application may hide the identifier of the cellular data service again, and may prompt the user: the application does not use the cellular data. Wherein the release network interface is configured to request release of the cellular data service.

The following specifically describes the hiding or displaying of the identifier of the cellular data service by the electronic device 100 by taking embodiments 4 to 8 as examples.

It should be noted that the electronic device 100 hides or displays the identification of the cellular data service on a User Interface (UI) through a phone manager.

For convenience of description, embodiments 4 to 8 each take as an example a scenario in which the electronic device 100 is in an SA network and switches from the SA network to Wi-Fi. Furthermore, embodiments 4 to 8 are all described by taking as an example the case where the cellular data service is not deactivated by the data communication method of embodiment 1.

Example 4

Fig. 9 is a schematic view of an information interaction scenario of the data communication method provided in embodiment 4.

As shown in fig. 9, the data communication method may include the steps of:

s901, in response to an instruction of the first application to connect to the wireless communication network, sending a first request network (RequestNetwork) message of the first application to the phone manager through the connection service.

Wherein the first request network message is for requesting a handover from the SA network to Wi-Fi. The first request network message includes a first application identification for identifying a corresponding first application.

It will be appreciated that each application program has a corresponding application identification. The electronic device 100 can distinguish different application programs by application identification. The application Identifier may include a Package Name (Package Name) or a Unique Identifier (UID) of the application program. The package name is a unique identifier of the application program, for example, the package name of the mobile phone QQ is com. The package name is set by the developer according to non-conflicting rules. The UID is used to identify an application, and is assigned by the system when the application is installed.

For example, the first request network message includes application identifier a, which indicates that application program a corresponding to application identifier a requests to switch from the SA network to Wi-Fi.

It will be appreciated that in some embodiments, when the application detects a signal from the wireless communication network, or when the application needs to connect to the wireless communication network, the electronic device 100 connects to the wireless communication network and then triggers an instruction to connect to the wireless communication network to switch from the SA network to Wi-Fi.

And S902, traversing the request network messages of the other application programs through the connection service.

The remaining applications refer to all applications on the electronic device 100 except the first application.

And S903, sending a Network Release Request (Release Network Request) message of other application programs to the telephone manager through the connection service.

Wherein the release network request message is for requesting suspension of the cellular data connection. The release network request message includes an application identification.

For example, the release network request message includes an application identifier B, which indicates that an application program B corresponding to the application identifier B requests to suspend the cellular data connection.

It can be understood that the specific implementation of the electronic device 100 sending the network release request message may refer to the descriptions of embodiments 1 to 3, and is not described herein again.

S904, the message deactivating the cellular data service is intercepted by any one of the phone manager, the radio interface layer and the modem processor.

For example, when the electronic device 100 connects to the SA network first and then to Wi-Fi, the electronic device 100 switches from the SA network to Wi-Fi, deactivating the cellular data. Specifically, all applications of electronic device 100 use cellular data, i.e., electronic device 100 is connected to the SA network, before the first application requests a connection to Wi-Fi. When a first application requests a Wi-Fi connection, device 100 needs to switch from the SA network to Wi-Fi, suspend the cellular data connection by sending a release network request message for the remaining applications, thereby deactivating the cellular data.

And S905, sending first indication information to the user interface through the telephone manager.

Wherein the first indication information is used for indicating the user interface to hide the identification of the cellular data service.

S906, the identification of the cellular data service is hidden through the user interface.

In this embodiment, when a first application of electronic device 100 requests a Wi-Fi connection, a handover from the SA network to Wi-Fi is achieved by sending a release network request message for the remaining applications to suspend the cellular data connection. The electronic device 100 sends a first indication to the user interface through the phone manager to indicate to the user interface to hide the identification of the cellular data service, thereby prompting the user to: the application does not use the cellular data.

S1007, in response to an instruction of the second application to connect to the cellular Network, sends a second Request Network (Request Network) message of the second application to the phone manager through the connection service.

Wherein the second request network message is for requesting cellular data services. The second request network message includes a second application identification for identifying a corresponding second application program.

For example, the second request network message includes application identifier B, which indicates that application program B corresponding to application identifier B requests the cellular data service.

It is understood that the second application may be the same as the first application or may be different from the first application. The second application is the first application and any of the remaining applications.

It will be appreciated that in some embodiments, the instruction to connect to the cellular network is triggered when the application detects a disconnection of the wireless communications network connection, or when the application needs to connect to the cellular network.

S1008, a resume cellular data connection message is sent to the connection service through any one of the phone manager, the radio interface layer, and the modem processor.

Specifically, after the second application has used up the cellular data, the electronic device 100 suspends the cellular data connection by sending a release network request message for the second application, thereby deactivating the cellular data.

It will be appreciated that in some embodiments, when the application detects a signal from the wireless communication network, or when the application needs to deactivate cellular data, the electronic device 100 connects to the wireless communication network, or neither the wireless communication network nor the cellular network, and then triggers an instruction to suspend the cellular data connection.

Wherein the third request network message is for requesting cellular data services. The third request network message includes a third application identification for identifying a corresponding third application program.

For example, the third request network message includes an application identifier C, which indicates that the application program C corresponding to the application identifier C requests the cellular data service.

The electronic device 100 sends a second indication to the user interface through the phone manager to instruct the user interface to display an identification of the cellular data service, thereby prompting the user to: the application is using or preparing to use the cellular data.

It will be appreciated that in other embodiments, there may be multiple applications requesting cellular data services before the electronic device 100 sends the first indication to the user interface via the phone manager. When there are one or more applications requesting the cellular data service, the electronic device 100 sends second indication information to the user interface through the phone manager to instruct the user interface to display an identification of the cellular data service, thereby prompting the user to: the application is using or preparing to use the cellular data.
