The software system of the electronic device 100 may employ a layered architecture, an event driven architecture, a microkernel architecture, a microservice architecture, or a cloud architecture. In the embodiment of the invention, taking an Android system with a layered architecture as an example, a software structure of the electronic device 100 is illustrated.

Fig. 2 is a software configuration block diagram of the electronic device 100 according to the embodiment of the present invention.

The layered architecture divides the software into several layers, each with distinct roles and branches. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into four layers, from top to bottom, an application layer, an application framework layer, an Zhuoyun row (Android run) and system libraries, and a kernel layer, respectively.

The application layer may include a series of application packages.

As shown in fig. 2, the application package may include applications for cameras, gallery, calendar, phone calls, maps, navigation, WLAN, bluetooth, music, video, short messages, 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. 2, the application framework layer may include a window manager, a content provider, a view system, a telephony manager, a resource manager, a notification manager, and the like.

The window manager is used for managing window programs. The window manager can acquire the size of the display screen, judge whether a status bar exists, lock the screen, intercept the screen and the like.

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 telephony manager is used to provide the communication functions of the electronic device 100. Such as the management of call status (including on, hung-up, etc.).

The resource manager provides various resources for the application program, such as localization strings, icons, pictures, layout files, video files, and the like.

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 notification manager may also be a notification in the form of a chart or scroll bar text that appears on the system top status bar, such as a notification of a background running application, or a notification that appears on the screen in the form of a dialog window. For example, a text message is prompted in a status bar, a prompt tone is emitted, the electronic device vibrates, and an indicator light blinks, etc.

Android run time includes a core library and virtual machines. Android run time is responsible for scheduling and management of the Android system.

The core library consists of two parts: one part is a function which needs to be called by java language, and the other part is a core library of android.

The application layer and the application framework layer run in a virtual machine. The virtual machine executes java files of the application program layer and the application program framework layer as binary files. The virtual machine is used for executing the functions of object life cycle management, stack management, thread management, security and exception management, garbage collection and the like.

The system library may include a plurality of functional modules. For example: surface manager (surface manager), media Libraries (Media Libraries), three-dimensional graphics processing Libraries (e.g., openGL ES), 2D graphics engines (e.g., SGL), etc.

The surface manager is used to manage the display subsystem and provides a fusion of 2D and 3D layers for multiple applications.

Media libraries support a variety of commonly used audio, video format playback and recording, still image files, and the like. The media library may support a variety of audio and video encoding formats, such as MPEG4, h.264, MP3, AAC, AMR, JPG, PNG, etc.

The three-dimensional graphic processing library is used for realizing three-dimensional graphic drawing, image rendering, synthesis, layer processing and the like.

The 2D graphics engine is a drawing engine for 2D drawing.

The kernel layer is a layer between hardware and software. The inner core layer at least comprises a display driver, a camera driver, an audio driver and a sensor driver.

The workflow of the electronic device 100 software and hardware is illustrated below in connection with capturing a photo scene.

When touch sensor 180K receives a touch operation, a corresponding hardware interrupt is issued to the kernel layer. The kernel layer processes the touch operation into the original input event (including information such as touch coordinates, time stamp of touch operation, etc.). The original input event is stored at the kernel layer. The application framework layer acquires an original input event from the kernel layer, and identifies a control corresponding to the input event. Taking the touch operation as a touch click operation, taking a control corresponding to the click operation as an example of a control of a camera application icon, the camera application calls an interface of an application framework layer, starts the camera application, further starts a camera driver by calling a kernel layer, and captures a still image or video by the camera 193.

The current networking scheme of the near field device generally adopts a Bluetooth or WIFI mode. Due to the high maturity of chips and low cost, bluetooth and WIFI functions are standard configurations for electronic devices.

There are some problems in the current networking mode of WIFI communication. WIFI networks are very vulnerable to ambient interference, such as sudden disconnection of WIFI, or insufficient bandwidth, etc. When the service is deployed, or after the service is deployed, if the electronic device cannot sense such events, the service deployment fails, for example, the electronic device always blocks on a certain interface and exits after timeout after a long time.

For example, when task migration is performed through the super terminal, the interface of the electronic device is suddenly blocked, and an error is returned after a long time, and the error is caused by serious interference around the channel, so that task deployment is overtime.

For example, under the hybrid networking, after the tablet mobile phone short video is successfully migrated, the tablet switches the short video stream back to the mobile phone to wait for 4s to prompt that the stream fails, but after 0.5s, the stream is successfully displayed.

Only 13 channels are available in the 2.4G band, and when an electronic device initiates a service, a hidden node near its periphery may already use a certain information, but the electronic device is not aware, so that there is interference. And co-channel interference may occur if there is overlap between the channels of adjacent electronic devices and the channels of the electronic device.

WIFI interference refers to that when an instruction such as task migration is performed by using a wlan0 interface, the available bandwidth of a channel may be insufficient, so that a single message is sent for more than 5-6 seconds to cause timeout (a specific time is defined by an application, and the timeout is generally caused when a certain time is exceeded).

The Bluetooth communication generally adopts a frequency hopping mechanism, and at the moment, a certain bandwidth is generally provided, and after the WIFI is completely interfered by the actual streaming test, the Bluetooth still reserves more than half of the bandwidth.

In summary, WIFI is easy to be interfered in the scheme of the current equipment networking, and the Bluetooth bandwidth is low. FIG. 3 is a schematic diagram of a current device networking system, as shown in FIG. 3, when a three-way navigation application of an electronic device initiates a distributed task migration service to an opposite device, the three-way navigation application sends migration data to a distributed task scheduling module of the electronic device, and the distributed task scheduling module starts related functions of the distributed task scheduling module of the opposite device and sends the migration data to the distributed task scheduling module of the opposite device through a soft bus; and the distributed task scheduling module of the opposite terminal equipment sends the instruction for starting the related function and the migration data to the three-party navigation module, and the three-party navigation module executes the operation corresponding to the related function according to the migration data. However, the soft bus of the current device networking system relies on a single network channel to perform service deployment when executing a target service (such as a distributed task migration service, etc.), and if the single network channel fails or is poor, the service fails.

Based on the technical problems, the embodiment of the invention provides a data migration method, electronic equipment and a networking system, wherein a target service can be dynamically switched between different network channels, and the service is kept to work on an optimal channel all the time.

Fig. 4 is a schematic diagram of a data migration system according to an embodiment of the present invention. As shown in fig. 4, the data migration system includes an application process 210, a soft bus process 220, a first network module 230, and a second network module 240. The application process 210 includes a target application 211 and a Software Development Kit (SDK) 212. The soft bus process 220 includes a network service module 221, an immunity module 222, and a migration module 223. It should be noted that, the application process 210, the soft bus process 220, the first network module 230, and the second network module 240 all belong to the same electronic device. For example, the electronic device includes a terminal device such as a mobile phone, a tablet computer, or a computer.

The first network module 230 is configured to send an online notification to the network service module 221 when the first network is online.

The network service module 221 is configured to record the first network online according to the online notification sent by the first network module 230.

The target application 211 is configured to send a target service instruction and target service data to the software development kit 212 in response to an operation of a user. The embodiment of the invention is applied to a scene that the target application sends the control signaling in a network formed by a distributed soft bus networking. The service types identified by the granularity statistics of the communication instance (session) created by the service include Stream, dfile, msg and Bytes. The Stream is mainly a screen-throwing service, and has high bandwidth requirement and high time delay requirement; dfile is mainly file sharing service, and has high bandwidth requirement and low time delay requirement; msg is mainly a control message type, and the delay requirement is high; bytes are mainly data block types and the latency requirements are general. In the embodiment of the invention, the target service data comprises data of a control message service or a service in which both control and data exist.

The software development kit 212 is used to send the target business instructions and the target business data to the web service module 221 in response to the user's operation.

The network service module 221 is further configured to send the target service data to the first network module 230 according to the target service instruction.

The first network module 230 is further configured to migrate the target service data to the peer device through the first network channel. The opposite terminal equipment comprises a tablet personal computer, a computer, an intelligent screen or a loudspeaker and the like.

The second network module 240 is configured to send an online notification to the network service module 221 when the second network is online.

In the embodiment of the invention, the first network and the second network are different.

Optionally, the first network and the second network are the same type of network. For example, the first network comprises WIFI1 and the second network comprises WIFI2; alternatively, the first network comprises bluetooth 1 and the second network comprises bluetooth 2; or the first network comprises zigBee1 and the second network comprises zigBee2, etc.

It should be noted that there are two modes of WIFI, one is AP (Access Point) -STA (Station) mode, for example, a mobile phone is used as STA, and a router is connected to the internet; another mode is Wifi peer-to-peer (with two roles, GO and GC), which can allow devices to directly connect to each other, so that users can perform one-to-one or one-to-many communication without using a local area network or AP (Access Point).

Due to chip hardware technology, current electronic devices already support multiple radio frequency resources, such as 2.4G and 5G simultaneously, so as to realize real hardware concurrency. In this scenario, for example, if the first network is a WIFI STA, the network of the first radio frequency where the first network is connected is poor, the second network may be completely switched to the second radio frequency, for example, the second network is P2P with 5G.

Due to hardware limitations, the same radio frequency resource is shared by the technologies applied by the same set of frequencies (2.4G and 5G are two sets of frequencies), e.g., a STA of 2.4G and a P2P of 2.4G typically share a set of radio frequency resources. Therefore, the STA of 2.4G, and the P2P switched to 2.4G generally have no change in network quality, because it is the same set of radio frequency for transceiving. Unless the AP (router) capability of the STA is weak, which leads to a larger delay, the RTT delay is detected in the embodiment of the present invention. But if STAs of the same set of frequencies are off-network, it is possible to switch to P2P and vice versa.

The embodiment of the invention is also suitable for a multi-chip scene, and two sets of radio frequencies (such as two sets of 5G) exist in the same frequency.

Among them, bluetooth includes classical Bluetooth (BR) and Bluetooth Low Energy (BLE).

In summary, the embodiment of the invention supports the switching of the migration target service data between the network channels of the same type.

Optionally, the first network and the second network are different types of networks. For example, the first network comprises WIFI and the second network comprises bluetooth; alternatively, the first network comprises bluetooth, the second network comprises WIFI, etc. The embodiment of the invention supports the switching of the migration target business data among different types of network channels.

It should be noted that, when the embodiment of the present invention switches network channels, the switched networks are selected according to the order of good network quality, second good network quality to bad network quality, so as to keep the service on the optimal network channel all the time.

The network service module 221 is further configured to record the second network online according to the online notification sent by the second network module 240.

The network service module 221 is further configured to send an evaluation instruction to the interference rejection module 222 when both the first network and the second network are online.

The anti-interference module 222 is configured to obtain a first measurement result by measuring a plurality of quality information of a first network according to the evaluation instruction, obtain a second measurement result by measuring a plurality of quality information of a second network, and obtain a network evaluation result according to the first measurement result and the second measurement result, and if the network evaluation result includes that the network quality of the first network is better than the second network and the network quality of the first network meets the target condition, continue to execute the operation of obtaining the first measurement result by measuring the plurality of quality information of the first network, and obtain the second measurement result by measuring the plurality of quality information of the second network.

In the embodiment of the invention, the quality of the network channel is influenced by the frequency domain aspect, the time domain and space domain aspect and the local aspect. The frequency domain aspect includes channel load, received signal strength indication (Received Signal Strength Indication, RSSI), number of wireless access points (Wireless Access Point, AP), noise floor, etc.; 4G and 5G work on a shared channel, compete with peripheral equipment in a carrier sense multiple access (Carrier Sense Multiple Access with Collision Avoid, CSMA/CA) mode with collision avoidance, and the number, signal strength, number, noise floor and the like of equipment deployed in a peripheral environment have certain influence on the competition of the current equipment. In terms of Time domain and space domain, when a large amount of Round Trip Time (RTT) flows, the router forwarding buffer may have lost packets and overflowed, so that a large amount of retransmission can be received only for the packet forwarded by the router; multiple Input Multiple Output (MIMO), single input single output (Simple Input Simple Output, SISO), management channel (MCC) and control channel (SCC) all have an impact on the quality of the network channel. On the local side, the local queue length may already be full, resulting in overflow; MCS and native emissivity can also affect the quality of the network channel.

For example, the first measurement result and the second measurement result may be presented in a scoring manner, whether the network quality meets the target condition is judged by setting a scoring threshold value, and if the measurement result of the network is greater than the scoring threshold value, the network quality meets the target condition; otherwise, the quality of the network does not meet the target condition.

The anti-interference module 222 is specifically configured to obtain a first measurement result by measuring a plurality of quality information of the first network and obtain a second measurement result by measuring a plurality of quality information of the second network during the period when the target application transmits the target service data.

It should be noted that the application process 210 and the soft bus process 220 may or may not be in the same process. When the application process 210 and the soft bus process 220 are in the same process, the RTT delay value is easily counted because the kernel ip protocol stack or the bluetooth protocol stack is called and packed in the same soft bus process. When the application process 210 and the soft bus process 220 are not in the same process, as shown in fig. 5, the application process invokes the software development kit by itself, and directly sends a packet through the kernel network module, while the soft bus does not sense the result; at the moment, a soft bus is required to sense a packet sending event, and then a kernel network module is sent to acquire recent packet sending time delay information; when the soft bus service process senses that the target application is used, network channel quality detection is performed, and the detection period does not cause frequent wake-up of the CPU during the packet sending of the target application.

The antijam module 222 is further configured to send the target service data to the second network module 240 to switch the first network channel for migrating the target service data to the second network channel if the network evaluation result includes that the network quality of the second network is better than the first network and the network quality of the second network meets the target condition.

In the embodiment of the present invention, the anti-interference module 222 of the soft bus process 220 dynamically detects channel quality of the first network and the second network, and if the first network signal is poor, switches to the second network channel, and performs redundant packet sending when necessary, so as to rapidly implement service deployment. In the process of executing the target service of the target application 211 by the electronic device, the soft bus process 220 implements the detection of the link delay by sending packets through the target application 211; meanwhile, the conditions of the WIFI, such as the frequency domain, the time domain, the local queue and the like, can be perceived, and the current bandwidth condition can be comprehensively judged. And when the first network quality is poor, deploying the service Session established in the first network channel to the second network channel at the same time. And when the first network quality is good, switching the network channel of the target service into the first network channel. When the first network and the second network are unstable, redundant packet sending and receiving end de-duplication are supported.

For example, as shown in fig. 6, when the WiFi interference is perceived to be serious, the WiFi network channel 1 corresponding to the Session1 is switched to the bluetooth network channel 3. Therefore, the control channel of the target service is always on-line, the signaling of the target service is always on the optimal network channel, and the target service can always reach the opposite terminal equipment in real time when being initiated.

It should be noted that, the process of switching the first network channel of the data of the migration target service to the second network channel includes a delimiting process. As shown in fig. 7, taking bluetooth switch to WiFi as an example, the data of the target service includes 123456, and the data currently received on the bluetooth channel includes 123; directly transmitting the data 456 which is not received currently on the Bluetooth channel on the WIFI channel; meanwhile, marking the delimited data 4; the receiving end receives the data of the Bluetooth channel and the WiFi channel simultaneously, and the data received first is forwarded preferentially, so that repeated data are removed.

The second network module 240 is further configured to migrate the target service data to the peer device through the second network channel.

Aiming at the data of the control message service or the service with both control and data, the embodiment of the invention preferentially ensures that the control message service is always available on an unstable network channel. Such as: and the distributed task can still continue to use the bottom link even after the WiFi is disconnected when the WIFI is unstable. If the target application 211 uses msg type Session, then the default is valid. If the Session type of the target application 211 belongs to bytes, the target application 211 evaluates that the data volume is very small, and the link of the data can be ensured by setting a parameter mode in a communication instance (openSession) stage. For the services with both control and data, the embodiment of the invention ensures that the control link is always available, and timely identifies and informs the abnormal scene of the data path. Such as a distributed clipboard, preferably ensures that its control link is available, but if the data link is broken, it is notified that the data link is abnormal, and the traffic module prompts the user or enables other links (such as P2P).

In the embodiment of the present invention, when the second network module 240 detects that WiFi is offline, an offline notification is sent to the network service module 221; the network service module 221 records the WiFi offline and notifies the target application 211 of the WiFi offline through the software development kit 212; when the target service includes the middle-sized service, the target application 211 establishes a high-speed channel with the opposite terminal device, and the target service data of the target application 211 is migrated to the opposite terminal device through the high-speed channel. For example, the high speed channel includes a P2P channel.

In the embodiment of the invention, the target service Session is not bound to a single network channel any more, and can be dynamically switched between different network channels; by detecting the quality of different types of network channels, some details of the Session operation of the target service are determined. Detecting the quality of a network channel at the moment of the packet sending of the target application, and avoiding frequent awakening of opposite-end equipment; determining whether the Session exists in a single network channel or redundant network channels according to the service quality; supporting switching to other network channels after the disconnection of a single network channel or redundant operation; the Session of the target service is kept online all the time. Further, after the network of the single type networking is offline, the embodiment of the invention supports the rapid notification through another type of network, and is used for the target application to decide whether to rapidly establish the high-speed channel such as P2P. The target application is notified of the heterogeneous medium offline, and can quickly decide whether to maintain the target service on the always-on network channel or otherwise establish the high-speed channel. For example, if the target traffic is a light signaling traffic (such as distributed feeder automation), it may continue to remain on the always-on network channel, where only a small amount of bandwidth is required for distributed deployment. For example, if the target service is a medium service, the establishment of the high-speed P2P channel is started at the moment of user initiation. Therefore, the lightweight service module is always on-line, and service deployment is not affected; the medium service supports the user to initiate an instant decision whether to enable the high speed P2P channel.

The embodiment of the invention is applied to a scene that the target application sends the control signaling in a network formed by a distributed soft bus networking. The service types identified by the granularity statistics with the session of the service creation include Stream, dfile, msg and Bytes. The Stream is mainly a screen-throwing service, and has high bandwidth requirement and high time delay requirement; dfile is mainly file sharing service, and has high bandwidth requirement and low time delay requirement; msg is mainly a control message type, and the delay requirement is high; bytes are mainly data block types and the latency requirements are general.

In this step, as shown in fig. 4, the anti-interference module obtains a first measurement result by measuring a plurality of quality information of a first network according to an evaluation instruction, obtains a second measurement result by measuring a plurality of quality information of a second network, obtains a network evaluation result according to the first measurement result and the second measurement result, and if the network evaluation result includes that the network quality of the first network is better than the second network and the network quality of the first network meets a target condition, continues to execute the operation of obtaining the first measurement result by measuring the plurality of quality information of the first network and obtaining the second measurement result by measuring the plurality of quality information of the second network.

In the embodiment of the invention, the quality of the network channel is influenced by the frequency domain aspect, the time domain and space domain aspect and the local aspect. The frequency domain aspect comprises channel load, RSSI, AP number, background noise and the like; 4G and 5G work on the shared channel, compete with peripheral equipment by using a CSMA/CA mode, and the quantity, signal strength, quantity, noise floor and the like of equipment deployed in the peripheral environment all have certain influence on the competition of the current equipment. In terms of time domain and space domain, when RTT flows in a large amount, a router forwarding buffer may have lost packets and overflowed, so that a large amount of retransmissions can be received only when a message forwarded by the router is caused; MIMO, SISO, MCC and SCC both have an impact on the quality of the network channel. On the local side, the local queue length may already be full, resulting in overflow; MCS and native emissivity can also affect the quality of the network channel.

In step 322, if the network evaluation result includes that the network quality of the second network is better than that of the first network, and the network quality of the second network meets the target condition, the anti-interference module sends the target service data to the second network module, so as to switch the first network channel for migrating the target service data to the second network channel.

In this step, as shown in fig. 4, if the network evaluation result includes that the network quality of the second network is better than that of the first network, and the network quality of the second network meets the target condition, the target service data is sent to the second network module, so as to switch the first network channel for migrating the target service data to the second network channel.

It should be noted that, after step 322, the antijam module still continues to perform the step of obtaining the first measurement result by measuring the plurality of quality information of the first network and obtaining the second measurement result by measuring the plurality of quality information of the second network.

In step 324, the second network module migrates the target service data to the peer device through the second network channel.

In this step, as shown in fig. 4, the second network module migrates the target service data to the peer device through the second network channel.

In the technical scheme of the data migration method provided by the embodiment of the invention, the target service Session is not bound to a single network channel any more, and can be dynamically switched between different network channels; by detecting the quality of different types of network channels, some details of the Session operation of the target service are determined. Detecting the quality of a network channel at the moment of the packet sending of the target application, and avoiding frequent awakening of opposite-end equipment; determining whether the Session exists in a single network channel or redundant network channels according to the service quality; supporting switching to other network channels after the disconnection of a single network channel or redundant operation; the Session of the target service is kept online all the time. Further, after the network of the single type networking is offline, the embodiment of the invention supports the rapid notification through another type of network, and is used for the target application to decide whether to rapidly establish the high-speed channel such as P2P. The target application is notified of the heterogeneous medium offline, and can quickly decide whether to maintain the target service on the always-on network channel or otherwise establish the high-speed channel. For example, if the target traffic is a light signaling traffic (such as distributed feeder automation), it may continue to remain on the always-on network channel, where only a small amount of bandwidth is required for distributed deployment. For example, if the target service is a medium service, the establishment of the high-speed P2P channel is started at the moment of user initiation. Therefore, the lightweight service module is always on-line, and service deployment is not affected; the medium service supports the user to initiate an instant decision whether to enable the high speed P2P channel.
