Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.

Fig. 1 is a schematic diagram of communication links of a network call, as shown in fig. 1, in which communication links are respectively mounted on a plurality of network cards (wireless network wlan0, wireless network wlan1 and mobile data network rmet_data0) of a mobile device, and when the network call is performed, one of the communication links is selected by default to establish a communication connection. At this time, there is a problem that the currently connected network is unobstructed, but the communication quality of the network communication is still poor due to the poor condition of the currently used communication link, so that the user experience is poor. If the network state is only interfered to solve the problem of poor network call quality, for example, the network on-off is detected by using some Transmission Control Protocol (TCP) packets and network control message protocol (ICMP) packets, the network call quality cannot be truly improved.

The embodiment of the present disclosure provides a communication control method, fig. 2 is a flowchart of a communication control method according to an exemplary embodiment, and as shown in fig. 2, the communication control method includes the following steps:

step 101, monitoring a quality prediction value of the call quality of a first communication link currently used by the mobile device when the mobile device is in a network call;

And 102, switching the communication link used by the network call from the first communication link to a second communication link when the quality predicted value of the first communication link does not meet the call condition of the network call.

It should be noted that the communication control method may be applied to any mobile device, and the mobile device may be: electronic devices such as smart phones, tablet computers, desktop computers or smart watches.

The mobile device has a third party application or system application installed thereon that can be used to conduct a network call.

The network call includes: voice calls or video calls.

The network call may be a call based on an instant messaging application and a non-instant messaging application. The non-instant messaging application employing a communication technology may be a circuit switched technology. For example, the instant messaging application may be a WeChat or a WeChat application. The non-instant messaging application may be a conference-like application that includes video calls.

Here, the problem of poor network call quality caused by uncertainty of network variation is affected by network on one hand and network on-off on the other hand, but the currently used communication link has a problem. For example, when the mobile device moves to the edge of the currently used wireless network, there may be a problem of network disconnection and a problem of communication link, so that the call quality of the ongoing network call will be affected and the user experience will be deteriorated.

The present disclosure is directed to a proposed solution where there is a problem with currently used communication links, resulting in poor quality of network calls. When the mobile device is in network call, the call quality of the first communication link currently used by the mobile device is monitored, and when the quality predicted value of the call quality of the first communication link is determined not to be in accordance with the call condition of the network call, the currently used communication link is switched, so that the network call quality is improved.

Here, the first communication link is any one of communication links under the first communication network.

In one embodiment, the first communication network comprises: any one of communication networks supported by the mobile device, for example, a 5G communication network, a 4G communication network, or a 3G communication network, etc.

In another embodiment, a first communication network includes: the mobile device supports a communication network in which traffic consumption cost is lower than a cost threshold and system bandwidth is greater than a bandwidth threshold.

The cost threshold and bandwidth threshold herein refer to a cost and bandwidth corresponding to the second communication network with relatively poor network status.

In another embodiment, the first communication network further comprises: the mobile device supports a communication network in which traffic consumption is below a cost threshold and the network has low stability.

Here, the stability of the network may be obtained by counting the number of network disconnection and the number of blocking in a period of time, and comparing the counted numbers of times under different communication networks.

Due to the different bandwidths of the communication networks, the corresponding network rates are also different. Different call effects can be obtained under different first communication networks, if the first communication network selects a network with large bandwidth and higher stability of the network, the problem of poor call quality may not occur, so if the first communication network is a communication network with large system bandwidth and high stability, the above procedure may not be executed.

It should be noted that, in the embodiment of the present disclosure, the system service (service) monitors the state change of the Audio Manager (Audio Manager) to determine whether the mobile device is in the network call. Specifically, when a voice call is in progress on the mobile device, the speaker and the microphone on the mobile device are occupied, and at this time, the Audio manager transmits a broadcast in an Audio mode, monitors the broadcast, and can determine whether the mobile device is currently in a call state.

Regarding the detection of whether the mobile device is currently in a call state, taking a third party application program that is performing a network call as a WeChat as an example, the detection of whether the mobile device is currently in a call state includes: after the WeChat is started, the service registers a broadcast receiver to listen to the broadcast for VOLUME change ACTION (volume_changed_action). When the micro-message is in a call state, the volume change action broadcast is sent, and at the same time, the service is triggered to check the working state (Mode) value of the Audio manager, and when the Mode value is 3 and the instant messaging application such as the micro-message is in a foreground or a background, the instant messaging application such as the micro-message is proved to be in the call state currently. When it is determined that the call is in a talk state, a detection of the quality of the call of the first communication link is performed.

As shown in fig. 3, the relevant steps for detecting whether the mobile device is currently in a call state include:

step 301, detecting a WeChat start;

step 302, a service monitors a broadcast sent by an Audio manager;

step 303, determining whether the mobile device is currently in a call state or not based on the monitoring result;

here, upon determining that the mobile device is currently in a talk state, go to step 304;

upon determining that the mobile device is not currently in a talk state, the process proceeds to step 302.

Step 304, monitoring a quality predictor of a call quality of a first communication link currently used by the mobile device is started.

Here, the detection of whether the mobile device is in a network call may be performed in real time; it may also be that execution is started upon detection that the target third party application is launched. For example, detection is performed upon detecting that a WeChat is opened. The present disclosure is not limited in this regard.

When the mobile equipment is determined to be in network communication, monitoring a quality predicted value of the communication quality of the currently used first communication link, determining whether the network communication is affected or not according to the size of the quality predicted value, switching the communication link after the network communication is determined to be affected, and selecting a second communication link to continue the network communication.

Here, the call quality of the first communication link is characterized by a quality prediction value.

The quality prediction value for monitoring the call quality of the first communication link currently used by the mobile device may be: and merging state parameters of each dimension on the first communication link to comprehensively determine the quality predicted value of the first communication link.

Since the quality of the call for the first communication link is affected by multifaceted factors, the quality of the call can be characterized by data in multiple dimensions. In order to more accurately give a judgment on the call quality of the first communication link, the accuracy can be enhanced by fusing state parameters of multiple dimensions.

The state parameters of each dimension include: communication delay parameters for characterizing delay, signal strength parameters for characterizing network signal strength, or speed parameters in the motion state of the mobile device.

Further, the call conditions of the network call include: the quality prediction value of the communication link is greater than or equal to a preset quality value. That is, when the quality prediction value of the first communication link does not meet the condition that the quality prediction value of the communication link is greater than or equal to the preset quality value, the communication link needs to be switched.

It should be noted that the switching may be implemented based on the created network optimization thread (Network Optimization), through which the interface established by the application on the mobile device in the network call is closed, and the route corresponding to the application in the network call is modified, through which switching the first communication link to the second communication link is performed.

When the mobile equipment is in network call, the communication link is switched when the quality predicted value of the first communication link does not accord with the call condition of the network call by monitoring the call quality of the first communication link currently used, so that the problem of blocking is solved, and the continuous running of the network call is ensured. In addition, when the network is unobstructed, the communication link state used is poor, which also affects the call, but the direct communication link monitoring method disclosed by the invention can be used for switching the communication link when the communication link is not ideal, so that the network call can be improved more fundamentally, and the problem of reduced call quality can be effectively solved.

In some embodiments, the monitoring the quality prediction value of the call quality of the first communication link currently used by the mobile device includes:

Here, the state parameters of the respective dimensions include: communication delay parameters, signal strength parameters, or speed parameters in a motion state. As such, in some embodiments, the collecting the plurality of state parameters of different dimensions of the mobile terminal during the network call includes: and acquiring a communication time delay parameter, a signal strength parameter and a speed parameter of the mobile terminal in a motion state of the mobile device when the mobile terminal uses the first communication link.

The communication quality of the first communication link is affected by multiple factors, each factor corresponds to a state parameter, and if only one state parameter is used for representing the communication quality on the communication link, prediction errors may exist or prediction is inaccurate, and a more accurate prediction effect can be relatively obtained by combining a plurality of state parameters to determine a quality prediction value of the communication quality of the first communication link.

In one embodiment, the merging the plurality of state parameters to obtain the quality prediction value of the call quality of the first communication link may be: combining the characteristics of the factors represented by the parameters to obtain a quality prediction value of the call quality of the first communication link; for example, the further the mobile device is from the signal source, the more problematic the quality prediction value of the call quality should be, then the state parameter for characterizing the distance between the mobile device and the signal source in the state parameters is determined, and then the quality prediction value can be determined based on the distance between the mobile device and the signal source and the delay value.

In another embodiment, the merging a plurality of the state parameters to obtain the quality prediction value of the call quality of the first communication link may be: and determining a quality prediction value of the call quality of the first communication link according to each state parameter and the corresponding weight coefficient. The assignment of the weight coefficients may be determined according to the degree of influence of each state parameter on the call quality in the history of use.

Here, the speed parameters of the mobile device in the motion state include: acceleration parameters or relative velocity parameters with respect to the signal source. The speed parameter may be obtained by detecting the creation of a Motion State (Motion State) thread. The three-axis acceleration of the linear accelerometer is obtained through a Motion State thread, and whether the mobile device is in a static State or a Motion State currently is judged through acceleration states of all directions.

Specifically, a Motion State thread is created, acceleration of X, Y and acceleration of a Z axis are obtained, the acceleration of the three axes is subjected to filtering processing, and the influence of noise of a sensor on State analysis is filtered. And finally, determining whether the triaxial acceleration subjected to noise removal is abnormal (for example, a large jump occurs), and fusing an abnormal speed parameter with an abnormal communication time delay parameter and a signal strength parameter to further determine a quality prediction value.

In some embodiments, fig. 4 is a step of detecting a speed parameter of a mobile device, as shown in fig. 4, comprising:

step 401, creating a Motion State thread;

step 402, based on the Motion State thread, acquiring a triaxial acceleration parameter of the mobile equipment in a Motion State;

here, the three-axis acceleration parameter characterizes acceleration parameters of the mobile device in three directions, such as acceleration parameters in the X-axis, Y-axis, and Z-axis.

Step 403, filtering the triaxial acceleration parameter;

here, the filtering process is used to remove noise in the acquired triaxial acceleration parameters.

Step 404, determining whether the filtered triaxial acceleration parameter is abnormal;

here, when it is determined that there is an abnormality in the axis acceleration parameter, the flow proceeds to step 405;

when it is determined that there is no abnormality in the shaft acceleration parameter, the process proceeds to step 402.

And step 405, fusing the abnormal triaxial acceleration parameter with the communication delay parameter and the signal strength parameter.

In some embodiments, the method further comprises:

detecting whether at least one state parameter abnormality exists in a plurality of state parameters.

In the embodiment of the disclosure, the problem existing in the first communication link can be reflected by the state parameter. Then the anomaly detection of these state parameters may be detected to find out the state parameters that are anomalous before the determination of the quality prediction value for the call quality of the first communication link is performed.

In this way, since the state parameters are abnormal, the possibility that the call quality of the first communication link is problematic is high, and if the state parameters are fused after the abnormality occurs, the calculation amount can be reduced for the subsequent fusion processing based on the state parameters.

Further, based on the detection of the anomaly, the merging the plurality of state parameters to obtain a quality prediction value of the call quality of the first communication link includes:

As described above, when the mobile device is running, each state parameter on the first communication link may be collected in real time, but if the collected state parameters are to be fused in real time, a quality prediction value is determined, the calculation amount may be large, and if there is no abnormality in the state parameters, the call quality on the first communication link may be in accordance with the call condition of the network call. And only after the abnormality occurs, the state parameters are fused, so that the calculated amount can be reduced for the fusion processing based on the state parameters.

In some embodiments, the detecting whether at least one state parameter anomaly exists among a plurality of the state parameters includes at least one of:

Here, the preset delay threshold represents a value corresponding to the normal delay of the call quality on the first communication link. Namely, when the communication delay parameter is smaller than the preset delay threshold, no jamming exists, and the conversation quality is good.

The normal call quality means that the call can be smoothly performed without any jamming.

The preset signal strength threshold represents a value corresponding to a network signal when the call quality on the first communication link is normal. For example, if the signal strength parameter is greater than the preset signal strength threshold, no jamming exists, and the call quality is good.

The preset acceleration threshold represents a value corresponding to acceleration when the conversation quality is normal on the first communication link. For example, if the speed parameter in the motion state is smaller than the preset signal strength threshold, no jamming exists, and the call quality is good.

Thus, the state parameters and the corresponding threshold values are compared to determine whether each state parameter is abnormal.

In some embodiments, the fusing the plurality of state parameters to obtain a quality prediction value of the call quality of the first communication link includes:

In the embodiment of the disclosure, the fusion of the state parameters is performed based on the content characteristics characterized by the state parameters.

In some embodiments, the greater the communication delay parameter is within a preset time period, the smaller the signal strength parameter is within a preset time period, and/or the greater the speed parameter is within a preset time period or remain stable, meaning that the mobile device is in a direction of movement away from the signal source.

In other embodiments, the direction of movement of the mobile device relative to the signal source may be determined based on the greater the communication delay parameter within a preset time period, and the information of the change in the signal strength parameter and the speed parameter.

The change information includes: the time at which the change starts or the duration of the change.

Specifically, a moving direction of the mobile device relative to the signal source is determined based on each state parameter, when it is determined that the mobile device is in a moving direction far away from the signal source, at this time, call quality on the first communication link is gradually deteriorated along with movement of the mobile device, and then the parameter of the communication delay parameter is gradually increased.

Here, the quality prediction value of the first communication link is characterized based on a delay value obtained by adding a gain value. Because the gain value is determined based on the signal strength parameter and the speed parameter, the quality prediction value determined by the signal strength parameter, the speed parameter and the communication delay parameter is integrated, and a more accurate prediction effect can be obtained.

In the embodiment of the disclosure, the correspondence between the signal strength parameter, the speed parameter and the gain value is pre-stored in the mobile device, and the correspondence can be determined based on the experience value in the history use. For example, when the signal strength parameter is 70 and the speed parameter is 20, the determined gain value is 10; when the signal strength parameter is 80 and the speed parameter is 20, the determined gain value is 20.

The gain value may be positive and negative, the determined gain value being positive when the mobile device is in a direction of movement away from the signal source.

Therefore, more accurate call quality judgment can be realized based on the gain added to the communication delay parameter.

In some embodiments, the determining the moving direction of the mobile device relative to the signal source based on the communication delay parameter, the signal strength parameter, and the variation of the speed parameter within a preset time period includes:

Here, when the mobile device is in a moving direction away from the signal source, the communication delay parameter is continuously increased within a preset time period.

When the signal strength parameter and the speed parameter change simultaneously, this means that the mobile device starts to move. The duration of the change in the signal strength parameter and the speed parameter also reflects the motion state information of the mobile device. For example, the moment when the movement starts and the moment when the movement ends.

Then, the embodiments of the present disclosure may consider that the mobile device moves in a moving direction away from the signal source when it is detected that the mobile device starts to move, and the larger the communication delay parameter becomes.

As shown in fig. 5, the merging the plurality of state parameters to obtain a quality prediction value of the call quality of the first communication link includes:

step 501, obtaining at least one abnormal state parameter;

step 502, counting communication delay parameters, and determining whether the communication delay parameters are continuously increased;

step 503, determining whether the signal strength parameter and the speed parameter have changed simultaneously and are continuously changed;

step 504, when the communication delay parameter continuously increases, the signal strength parameter and the speed parameter change simultaneously, and the change is continuously performed, increasing a gain value for the communication delay parameter according to the signal strength parameter and the speed parameter;

Step 505, determining whether the communication delay parameter after the gain value is increased exceeds a threshold value;

step 506, when the communication delay parameter with the gain value exceeds the threshold value, determining that the call quality of the first communication link does not meet the call condition of the network call.

Here, the delay value obtained by adding the gain value is the quality prediction value. If the delay value obtained after the gain value is added is still greater than the threshold value, the current call quality of the first communication link can be determined to be not in accordance with the call condition of the network call.

In some embodiments, the method further comprises:

In the embodiment of the disclosure, the communication delay of the communication link mounted on each network card (such as wlan0, wlan1 or rmet_data0) is monitored, and based on determining the quality predicted value corresponding to each communication link, the quality predicted value is compared with a set threshold (step 606 above), when a communication link with the quality predicted value smaller than the threshold exists in the quality predicted value corresponding to each communication link, the communication link with the quality predicted value smaller than the threshold is considered to be an alternative communication link with the call quality conforming to the call condition of the network call.

If the communication quality of the first communication link is not good and the communication condition of the network communication is not met, the communication link used by the network communication can be switched from the first communication link to any one of the alternative communication links.

In order to make the call quality better, the embodiment of the disclosure may select the communication link with the best call quality from the alternative communication links as the second communication link.

In some embodiments, the switching the communication link used by the network call from the first communication link to the second communication link includes:

In the embodiment of the disclosure, when it is determined that the call quality of the first communication link is poor and the call condition of the network call is not met, the first communication link may be switched.

In a specific handover, when it is determined that a communication link is required, the embodiment of the disclosure creates a network optimization (Network Optimization) thread, and controls to close all interfaces (sockets) established by the application program in network communication on the mobile device through the thread, and modifies a route corresponding to the application program in network communication. Here, in the modification route, the application program is designated to send a data packet through the designated network card to establish the original call network.

And sending the data packet through the designated network card, namely establishing the original call network through the communication link mounted on the designated network card. The designated network card refers to a network card mounted on the second communication link to be switched.

As shown in fig. 6, the switching step includes:

step 601, creating a network optimal (Network Optimization) thread;

step 602, obtaining a determination result of whether the call quality of the first communication link meets the call condition of the network call;

step 603, determining whether a communication link with optimal call quality in the alternative communication links is obtained;

step 604, where the determination result is: when the call quality of the first communication Link does not accord with the call condition of the network call and the optimal communication Link is obtained, all interfaces (sockets) under the application program of the network call are controlled to be closed through a network Link (Net Link) communication mechanism;

step 605, modifying the network card corresponding to the application program in network communication;

here, the network card corresponding to the application program in network communication is changed through the routing table.

Step 606, based on the modified route, the original call network is established, and the switching from the first communication link to the second communication link is completed.

In this way, by utilizing the characteristic that the application program in network communication disconnects and reconnects, when the network needs to be optimized, all sockets established by the application program in network communication are closed, the default route of the application program in network communication is modified, the application program in network communication is designated to send a data packet through the designated network card, and at the moment, the application program in network communication can rapidly establish an original communication network through a new network card, so that the switching of a communication link is realized.

The present disclosure also provides the following embodiments:

fig. 7 is a second flowchart of a communication control method according to an exemplary embodiment, as shown in fig. 7, including:

step 701, detecting the state of an application running on a mobile device;

here, the application is a third party application that can be used to conduct a network call.

The state of the application program includes: in a network talk state, or not in a network talk state.

step 703, when it is determined that the application program is in a network call, collecting a plurality of state parameters of different dimensions of the mobile device in the network call;

Here, the state parameters include: a communication delay parameter, a signal strength parameter or a speed parameter of the mobile device in a motion state.

Step 704, detecting whether at least one state parameter abnormality exists in a plurality of state parameters;

here, when it is detected that there is at least one state parameter abnormality, go to step 705;

when it is detected that there is no abnormality in at least one state parameter, the process proceeds to step 703.

Step 705, when detecting that at least one state parameter is abnormal, fusing a plurality of state parameters to obtain a quality prediction value of the call quality of the first communication link;

step 706, determining whether the network call quality meets the call condition of the network call based on the quality prediction value;

here, the quality prediction value is compared with a set threshold value, and whether the network call quality meets the call condition of the network call is determined according to the comparison result.

When the network call quality meets the call condition of the network call, go to step 703;

when the network call quality does not meet the call condition of the network call, the process proceeds to step 707.

In step 707, when it is determined that the call condition of the network call is not met, it is determined to switch the communication link used by the network call from the first communication link to the second communication link.

According to the communication control method provided by the embodiment of the disclosure, when the mobile equipment is in a network call, the communication link is switched when the quality predicted value of the first communication link does not accord with the call condition of the network call by monitoring the call quality of the currently used first communication link, so that the problem of stuck is solved, and the continuous running of the network call is ensured.
