Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
In the description of the present application, "plurality" means two or more unless otherwise specified. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
Referring to fig. 1, an environment diagram of an implementation environment provided by an exemplary embodiment of the present application is shown, where the implementation environment includes a terminal 110 and a server 120.
The terminal 110 is an electronic device having a WiFi network connection and a mobile data network connection function. The mobile data network may be a third Generation mobile communication technology (3rd-Generation, 3G) network, a fourth Generation mobile communication technology (4th-Generation, 4G) network, a Long Term Evolution (LTE) network, a fifth Generation mobile communication technology (5th-Generation, 5G) network, or the like.
When the terminal 110 starts the WiFi network connection function, the terminal 110 may search for a nearby WiFi network and perform internet access by accessing the WiFi network; when the mobile data network connection function is turned on, the terminal 110 can perform internet access through the mobile data network. The WiFi network connection function and the mobile data network connection function can be started simultaneously.
In addition, at least one application is installed in the terminal 110, and the at least one application requires internet access, and the application may be an instant messaging application, an email application, a social application, a video playing application, a browser application, a game application, a news reading application, and the like.
The terminal 110 is connected to the server 120 through a WiFi network or a mobile data network.
The server 120 is a server, a server cluster formed by a plurality of servers, or a cloud computing center. In the embodiment of the present application, the server 120 is a background server of the application program in the terminal 110. During the running process of the application program, the local network data is sent to the server 110, and the network data sent by the server 110 is received. The terminal 110 may perform network data transmission with multiple servers 120 (corresponding to different applications running in foreground or background in the terminal 110) at the same time.
In one possible application scenario, the terminal 110 establishes a mobile data network connection and transmits network data of the application program through the mobile data network connection. When the mobile terminal moves to the coverage of the WiFi network and the WiFi network is available, the user triggers a network handover request, and after receiving the network handover request, the terminal 110 tries to establish a WiFi network connection on the premise of maintaining the mobile data network connection for a predetermined time. When the WiFi network connection is established within the preset time, the terminal uses the WiFi network connection for transmitting network data during switching, and the first network connection is disconnected, so that network switching is realized.
Optionally, the implementation environment may further include a target server, and the terminal 110 accesses the target server through the established network connection, so as to obtain the quality of the network connection, and further determine whether network handover is required.
The following embodiments are described by taking an example in which the network handover method is applied to the terminal 110 in fig. 1.
Referring to fig. 2, a flowchart of a network handover method according to an exemplary embodiment of the present application is shown. The present embodiment is illustrated by applying the method to the terminal 110 in fig. 1. The method comprises the following steps:
The first network connection is a mobile data network connection or a WiFi network connection.
In a possible application scenario, when the terminal is out of the coverage of the WiFi network, or the terminal is in the coverage of the WiFi network but the WiFi network is not available, or the terminal does not turn on the WiFi network connection function, the terminal transmits network data through the mobile data network connection.
In another possible application scenario, when the terminal is within the coverage of the WiFi network, the WiFi network is available, and the WiFi network connection function is turned on, the terminal transmits network data through the WiFi network connection.
Optionally, the network data includes data transmitted by foreground applications, background applications, and/or system services.
In one possible implementation, after receiving the network handover request, the terminal starts a Timer (Timer) and attempts to establish the second network connection within a Timer duration specified by the Timer. If the second network connection is established within the time length of the timer, execute step 203; if the second network connection is not established within the time length of the timer, the first network connection is disconnected, and the second network connection is reestablished, so that the first network connection is prevented from being occupied for too long time (especially when the first network connection is a mobile data network connection).
Optionally, the network connection mode is one of a WiFi network connection and a mobile data network connection, that is, when the first network connection is the mobile data network connection, the second network connection is the WiFi network connection; when the first network connection is a WiFi network connection, the second network connection is a mobile data network connection.
Optionally, the network handover request is triggered manually by a user, or automatically by the terminal.
When the network handover request is manually triggered by the user, in one possible embodiment, the WiFi network connection function is in an off state while the terminal transmits network data through the mobile data network connection. When the user manually starts the WiFi network connection function and the WiFi network exists, the terminal receives the network switching request and requests to switch to the WiFi network.
When the network handover request is automatically triggered by the terminal, in one possible embodiment, the WiFi network connection function is in an on state when the terminal transmits network data through the mobile data network, and when there is no WiFi network (or no WiFi network available). When the terminal moves to a place where the WiFi network is available, the terminal automatically triggers a network switching request to switch to the WiFi network.
In other possible embodiments, when the terminal transmits network data through the WiFi network connection, the user may trigger the network handover request by manually turning off the WiFi network connection function (in this case, the terminal needs to maintain the WiFi connection within the duration of the timer).
The terminal still transmits network data through the first network connection in the process of trying to establish the second network connection within the time length of the timer, so that transmission interruption in the network switching process is avoided; meanwhile, the timer is arranged, so that the flow consumption caused by continuously using the first network connection to transmit the network data when the second network connection cannot be established for a long time is avoided.
Optionally, the duration of the timer may be a fixed value, or may be dynamically determined according to the current foreground application. For example, the timer may have a duration of 3 s.
As shown in fig. 3, the terminal transmits network data through the first network connection from time 0, and when a network handover request is received at time t, the terminal starts a timer, continues to transmit network data through the first network connection, and attempts to establish a second network connection.
And when the second network connection is successfully established within the time length of the timer and the second network connection can be accessed, the terminal switches the network data to the second network connection for transmission.
As shown in fig. 3, when the terminal establishes the second network connection at time t '(t' -t ≦ timer duration), the terminal performs network data transmission through the second network connection.
Accordingly, when the second network connection is successfully established, the terminal disconnects the first network connection.
As shown in fig. 3, when the terminal establishes the second network connection at time t '(t' -t ≦ timer duration), the terminal disconnects the second network connection.
In one possible application scenario, a user uses a terminal to play an online game in a mobile data network connection state, and when the user moves to a place (such as a home) where a WiFi network is available and the terminal turns on a WiFi network connection function, the terminal attempts to establish a WiFi network connection within 3s while maintaining the mobile network connection. And if the WiFi network connection is successfully established within 3s, the terminal switches to use the WiFi network to transmit network data and disconnects the mobile data network. In the whole network switching process, network data transmission is not interrupted, the smoothness of game operation is ensured, and the phenomenon of disconnection or blockage is avoided.
To sum up, in the embodiment of the present application, when a network switching request is received during a process of transmitting network data by using a first network connection, a terminal tries to establish a second network connection within a timer duration, and after establishing the second network connection within the timer duration, switches to use the second network connection to transmit the network data, thereby disconnecting the first network connection; compared with the prior art that the current network connection is immediately disconnected and then a new network connection is established, in the embodiment of the application, a buffer period is set before the network connection is disconnected, and the new network connection is tried to be established in the buffer period, so that the network terminal caused by the fact that the current network is immediately disconnected is avoided, the influence of the network switching process on network data transmission is reduced, and the effect of switching the network without awareness is achieved.
In the actual application process, when the application program operated by the foreground is a video playing application program, a browser application program or a news reading application program, because a preloading mechanism exists in the operation process of the application program and the requirement on the network real-time property is low, even if the network switching process is interrupted, the user is not easy to perceive, and the use of the user is not influenced. When the application program running on the foreground is an instant messaging application program or a game application program, because the frequency of network data transmission of the application program is high and the requirement on the real-time performance of the network is high, the interruption in the network switching process is easily detected by a user (usually, the disconnection or the blockage occurs), and the use of the user is influenced. Thus, in one possible embodiment, the terminal enables the network-unaware switching function only when the foreground runs a specific application. The following description will be made by using exemplary embodiments.
The step 201 may be referred to in the implementation manner of this step, and this embodiment is not described herein again.
In one possible implementation mode, the terminal acquires a target application program (installed in the terminal) needing to enable the non-inductive network switching function in advance, and stores a target application package name of the target application program. The target application is an application with a network real-time requirement (delay, packet loss rate, etc.) higher than a threshold, for example, the target application is a game application and/or an instant messaging application.
When receiving a network switching request, the terminal acquires an application package name (packageaname) of a foreground application program, detects whether the application package name belongs to a target application package name, determines that the foreground application program belongs to the target application program if the application package name belongs to the target application package name, and executes step 403; otherwise, determining that the foreground application does not belong to the target application.
The foreground application program refers to an application program which is switched from a background to a foreground for running, or an application program which is directly started in the foreground.
Because the terminal has the possibility of failure when establishing the second network connection, in order to ensure that the problem of network interruption does not occur to the application program with higher network real-time requirement in the network switching process as much as possible, the terminal configures longer timer duration, that is, configures longer buffer period for the application program with higher real-time requirement.
In a possible implementation manner, the terminal sets a network requirement level for each target application program in advance according to the network real-time requirement of each target application program, wherein the higher the network real-time requirement of the target application program is, the higher the corresponding network requirement level is.
Illustratively, the correspondence between the application and the network demand level is shown in table one.
Watch 1
And when the application program operated by the foreground is the target application program, the terminal further acquires the network requirement level corresponding to the target application program.
For example, when the terminal determines that the application package name of the foreground application is the target application "xx fight", the terminal further determines that the network demand level corresponding to "xx fight" is 3-level.
And step 404, determining the time length of the timer according to the network demand level, wherein the network demand level and the time length of the timer have positive correlation.
Further, the terminal determines the time length of the timer corresponding to the acquired network demand level according to the acquired network demand level, wherein the higher the network demand level is, the longer the corresponding time length of the timer is, that is, the longer the time for the terminal to attempt to establish the second network connection is.
Illustratively, the correspondence between the network demand level and the timer duration is shown in table two.
Watch two
| Network demand level | Duration of timer |
| 1 | 3s |
| 2 | 4s |
| 3 | 5s |
| 4 | 6s |
With reference to the example in step 403, the terminal determines that the timer duration is 5 s.
It should be noted that, the above steps 403 and 404 are optional steps, that is, the duration of the timer may be a fixed value, and after the terminal determines that the application running in the foreground is the target application, the terminal directly attempts to establish the second network connection within the duration of the timer. The embodiment of the present application does not limit this.
And the terminal tries to establish the second network connection within the determined time length of the timer.
Because the target application program has a high real-time requirement on the network, if the network quality of the second network is poor, the operation quality of the target application program is affected after the network data is switched to the second network for connection, and especially, under the condition that the terminal automatically performs network switching (for example, the terminal which starts the WiFi network connection function automatically switches to the WiFi network after entering the WiFi network coverage area), the user experience is greatly affected.
In order to avoid the above problem, in one possible embodiment, the present step includes the following steps.
If a second network connection is established in the time length of the timer, performing network connection quality test on the second network connection and the first network connection to obtain a test result, wherein the test result comprises at least one of delay and packet loss rate.
In one possible implementation, the terminal periodically accesses the target server through the first network connection while transmitting the network data through the first network connection, so as to obtain a first test result including delay and packet loss rate. Wherein a lower delay and/or a lower packet loss rate indicates a better quality of the network connection.
For example, the terminal periodically pings a target domain name (corresponding to the target server) through the first network connection, so as to calculate the delay and packet loss rate of the first network connection according to the response result of the target server. The embodiment of the present application does not limit the manner of measuring the delay and the packet loss rate.
Correspondingly, after the terminal establishes the second network connection, the network connection quality is measured in a manner similar to the first network connection, so that a second test result is obtained.
And secondly, if the test result indicates that the quality of the second network connection is better than that of the first network connection, switching to use the second network connection to transmit the network data.
In a possible implementation, when the test result indicates that the delay of the second network connection is lower than the delay of the first network connection, and/or indicates that the packet loss rate of the second network connection is lower than the packet loss rate of the first network connection, the terminal determines that the quality of the second network connection is better than the quality of the first network connection, so as to switch to use the second network connection for transmitting the network data.
Optionally, if the test result indicates that the quality of the first network connection is better than the quality of the second network connection, and when the network connection request is automatically triggered by the terminal (network switching is performed manually by a non-user), the terminal continues to transmit network data through the first network connection and continues to monitor the quality of the second network connection. And when the quality of the second network connection is better than that of the first network connection or the target application program finishes the life cycle, the terminal switches to use the second network connection to transmit the network data.
Step 204 may be referred to in the implementation manner of this step, and this embodiment is not described herein again.
Optionally, if the second network connection is not established within the duration of the timer and the network switching request is triggered by the user, the terminal disconnects the first network connection and reestablishes the second network connection.
Optionally, if reestablishing the second network connection fails, or the established second network connection is unavailable, the terminal displays a prompt message to prompt the user that no WiFi network is available currently.
In the above embodiment, the network data transmitted by the target application may include User Datagram Protocol (UDP) data and/or Transmission Control Protocol (TCP) data. The UDP data generally includes data with high requirements for transmission delay, such as control commands in a game, and the TCP data generally includes data with high requirements for transmission reliability, such as login information in a game. Since the transmission of TCP data depends on the TCP connection established between the terminal and the server, re-establishing the TCP connection may cause the connection to be disconnected.
Therefore, in order to further reduce the influence of network handover on the application program, when the application program operated by the foreground is the target application program, and the network handover request is actively triggered by the terminal (when the network handover is not manually performed by the user, it indicates that the intention of network handover is not strong), and the network data transmitted by the target application program contains TCP data and UDP data, when the target application program is in the foreground operation state, the second network connection is switched to transmit UDP data, and the first network connection is continuously used to transmit TCP data. And when the target application program finishes the life cycle or is switched to the background operation, the terminal switches to use the second network connection to transmit the TCP data and disconnects the first network connection.
In a possible implementation manner, the terminal needs to identify the network data of the target application according to a Unique Identifier (UID) of the target application, and identify whether the network data of the target application contains TCP data, where a protocol number of the UDP data is 17, and a protocol number of the TCP data is 6.
When the network data of the target application program is identified to contain TCP data and UDP data, the terminal keeps the first network connection, and switches to use the second network connection to transmit the UDP data and uses the first network connection to transmit the TCP data when the target application program is in a foreground operation state. And when the target application program finishes the life cycle or is switched to the background operation, the terminal switches to use the second network connection to transmit the TCP data and disconnects the first network connection.
In this embodiment, the terminal establishes the network connection dual-path only when the foreground application is a target application with a high requirement on network real-time, so as to implement the non-inductive network switching and avoid resource waste caused by establishing the network connection dual-path for a low network real-time requirement.
In this embodiment, the terminal determines the duration of the timer configured for the target application according to the network requirement level corresponding to the target application, so that the application requiring network real-time performance has a longer network switching buffer period, thereby avoiding data interruption of the application in the network switching process and improving the operation quality of the application.
In addition, in this embodiment, the terminal performs a network quality test on the first network connection and the established second network connection, and switches the second network connection for data transmission when the quality of the second network connection is the quality of the first network connection, thereby avoiding a problem of poor running quality of an application program after switching networks.
In one possible scenario, the terminal fails to establish the second network connection for the timer duration, but the target application transfers a large amount of network data for the timer duration (e.g., when the target application is a gaming application, a large amount of network data needs to be transferred when a group of things is in play). In this case, if the first network connection is directly disconnected, a network interruption will be caused, which affects the normal operation of the target application.
In order to ensure the normal operation of the target application under the above-mentioned conditions, on the basis of fig. 4, as shown in fig. 5, the following steps may be further included after step 405.
Step 409, acquiring a target data volume transmitted through the first network connection within the time length of the timer, wherein the target data volume is the data volume of the network data corresponding to the target application program.
And in the process of trying to establish the second network connection, the terminal counts the data volume of the network data corresponding to the target application program transmitted through the first network connection.
In a possible implementation manner, the terminal identifies the network data of the target application program according to the UID of the target application program, and further counts the data volume of the network data.
For example, the terminal acquires a target data volume of 200 KB.
Step 410, if the second network connection is not established within the timer duration and the target data volume is greater than the data volume threshold, the timer duration is extended.
When the second network connection is not established within the time length of the timer, the terminal further detects whether the target data volume is larger than the data volume threshold value, if so, the target application program is determined to be in a data transmission active state, and in order to avoid the influence of the network switching process on the normal operation of the target application program, the terminal prolongs the time length of the timer (continuously transmits network data through the first network connection and tries to establish the second network connection); if the data transmission rate is less than the preset value, the target application program is in a data transmission inactive state, and the data transmission short-time terminal cannot cause great influence on the program application, so that the terminal directly disconnects the first network connection and reestablishes the second network connection. For example, the threshold data amount may be 150 KB.
Optionally, the data amount thresholds corresponding to different target application programs are different, and this is not limited in this embodiment of the application.
Optionally, the time length of the timer may be extended by a fixed value, for example, by 5s, or by twice; the extension amount of the timer period may also be dynamically determined according to a ratio of the target data amount to the data amount threshold, for example, the extension amount is (target data amount/data amount threshold) × constant. The embodiment of the present application does not limit the specific manner of extending the time length of the timer.
Optionally, if the second network connection is not established within the extended duration of the timer, the terminal disconnects the first network connection and reestablishes the second network connection.
In this embodiment, when the amount of data transmitted by the target application program in the timer duration is large and the second network connection is not established in the timer duration, the terminal extends the timer duration and continues to try to establish the second network connection, thereby avoiding the influence on the operation of the target application program caused by directly disconnecting the first network connection.
