Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

The terms "first", "second", etc. in the specification and claims of this application are used to distinguish similar objects. It is not used to describe a specific order or sequence. It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and/or" in the specification and claims means at least one of the connected objects, and the character "/" generally indicates that the objects associated with each other are in an "or" relationship.

The network switching method and device provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

As shown in FIG1 , an embodiment of the present application provides a network switching method, including:

Step 102: During a call through a first network, a first evaluation value of voice quality is obtained.

In one embodiment, the first evaluation value includes: MOS value or packet loss rate.

In this embodiment, the first evaluation value may be a Mean Opinion Score (MOS) value, wherein the MOS value is a general or average opinion score of all audio files calculated after obtaining the score given by each listener, wherein the larger the MOS value, the better the voice quality, and conversely, the smaller the MOS value, the worse the voice quality.

In this embodiment, the first evaluation value may be selected as a packet loss rate, wherein the packet loss rate refers to the ratio of the number of lost data packets in the test to the number of sent data groups. Specifically, in the embodiment of the present application, the packet loss rate may be the ratio of the number of data packets received by the electronic device to the number of data packets sent by the base station to the electronic device within a preset time period during a call. The preset time period may be selected according to actual usage needs, and will not be described in detail here.

In one of the embodiments, the first evaluation value is obtained periodically, that is, during a call through the first network, the first evaluation value of the voice quality is periodically obtained to achieve continuous monitoring of the voice quality during the call.

Step 104 , when the first evaluation value is less than or equal to the first threshold, obtain a first duration during which the first evaluation value is less than or equal to the first threshold.

In this embodiment, when the acquired first evaluation value is less than the first threshold, timing starts, and the relationship between the updated first evaluation value and the first threshold is determined. If the updated first evaluation value is still less than the first threshold, an interval duration is accumulated, and the cycle is repeated. The accumulated duration is the continuous duration, wherein the interval duration is the duration between each two acquisitions of the first evaluation value.

Step 106: When the first duration is greater than or equal to the first duration, switch the electronic device from the first network to the second network.

In this embodiment, the first duration can be determined according to actual usage requirements, wherein the first duration is greater than the interval duration.

Among them, the first network is the New Radio (NR) network, and the second network is the Long Term Evolution (LTE) network.

Among them, NR, also known as 5GNR, is a global 5G standard with a new air interface design based on orthogonal frequency division multiplexing (OFDM) technology.

Among them, LTE, a universal mobile communication technology, is the long-term evolution of the Universal Mobile Telecommunications System (UNTS) technical standard developed by the 3rd Generation Partnership Project (3GPP).

In this embodiment, a first evaluation value of the voice quality during a call is obtained, so as to measure the quality of the voice during a call in the current network according to a comparison result between the first evaluation value and the first threshold value, and then switch the network of the electronic device when the current voice quality is poor. By switching the network of the electronic device, the voice quality during a call is improved, thereby meeting the user's needs for call quality.

By obtaining a first evaluation value, the first evaluation value is continuously compared with a first threshold value, and when the first evaluation value is less than or equal to the first threshold value, the duration during which the first evaluation value is less than or equal to the first threshold value, that is, the first duration, is obtained, and the first duration is compared with the first duration to judge the call quality over a period of time. When the first duration is greater than the first duration, the network of the electronic device is switched from the first network to the second network.

In any of the above embodiments, the network switching method further includes: obtaining a call status of the electronic device; and when the call status is to maintain the call, maintaining the network of the electronic device unchanged until the call ends.

In this embodiment, the call status is obtained and the network is kept unchanged according to the call status, so as to reduce the frequency of network switching and the impact of network switching on the call, such as reducing the sound freeze at the moment of switching.

Exemplarily, the network before switching is VoNR, and the network after switching is a voice call under the Voice of Long Time Evolution (VoLTE) bearer standard, and in subsequent calls, the network of the electronic device always maintains a voice call under the Voice of Long Time Evolution (VoLTE) bearer standard.

In one embodiment, switching the network of the electronic device specifically includes: sending the switched network to the modem so that the modem acts according to the switched network; when receiving confirmation information fed back by the modem, the network switching of the electronic device is completed.

In this embodiment, the switched network is sent to the modem so that the modem can perform actions according to the switched network, thereby achieving network switching. In this process, the network switching is terminated by limiting the time when confirmation information fed back by the modem is received, so as to ensure that the network is switched.

As shown in FIG. 2 and FIG. 3 , the network switching method includes:

Step 202: The electronic device triggers a voice call under VoNR;

Step 204, determining whether the voice call under VoNR is ended at each interval of a time length TI, and if the determination result is yes, ending; if the determination result is no, executing step 206;

Step 206, detecting the MOS value of the voice call under VoNR;

Step 208, determining whether the MOS value of the voice call under VoNR is lower than the first threshold and maintained for the first duration, if the determination result is yes, executing step 210, if the determination result is no, executing step 206;

Step 210, switching the voice call under VoNR to the voice call under VoLTE;

Step 212, determine whether the call is ended. If the judgment result is no, execute step 212. If the judgment result is yes, end.

As shown in FIG. 3 , an access point (AP) may be an upper layer application module corresponding to a modem, wherein the command sent by the AP includes the switched network so that the modem can feedback (Acknowledge, ACK) confirmation information (i.e., the confirmation information mentioned above).

In one of the embodiments, after switching the electronic device from the first network to the second network when the first duration is greater than or equal to the first duration, the method further includes: obtaining a second evaluation value of voice quality during a call via the second network; obtaining a second duration when the second evaluation value is greater than or equal to the second threshold when the second evaluation value is greater than or equal to the second threshold when the second duration is greater than or greater than the second duration.

In this process, the first network can be used as a priority network under the premise of ensuring the call quality.

The second evaluation value can represent the quality of the network environment under the current network. Specifically, the quality of the network environment can be understood as the network delay and data transmission rate. When the quality of the network environment is good, the network delay is low and the data transmission rate is high. Conversely, when the quality of the network environment is poor, the network delay is high and the data transmission rate is low.

Specifically, the second evaluation value is obtained periodically, wherein the second evaluation value may have the same acquisition period as the first evaluation value, and the second duration is determined in the same manner as the first duration, which will not be described in detail herein.

In this process, the first network is used as the preferred network.

In the above embodiment, the second duration can be set according to actual usage needs and is not limited here.

In one of the embodiments, during a call through a second network, obtaining a second evaluation value of voice quality specifically includes: obtaining a call status of the electronic device at every third time interval; and obtaining the second evaluation value of voice quality when the call status is to maintain the call.

In this embodiment, considering that the purpose of network switching in this application is to ensure the call quality, it is necessary to determine whether the call is ended, and obtain the call status of the electronic device at every third time interval, so that when the call status is to maintain the call, a second evaluation value is obtained to implement network switching control during the process.

In the above embodiment, the third duration can be set according to actual usage needs and is not limited here.

In the above embodiment, the call status can be determined by whether the application called on the electronic device is ended. Specifically, when the call is held, the application executing the call keeps running, and after the call ends, the application executing the call ends running. Therefore, the call status can be determined by detecting whether the application executing the call is running.

In one embodiment, after switching the electronic device from the second network to the first network, the method further includes:

The first evaluation value is updated; and according to the updated first evaluation value, the network of the electronic device is controlled to switch between the first network and the second network.

In this embodiment, the first evaluation value is updated so that network switching is achieved based on the updated first evaluation value, the first threshold and the first duration. In this process, by switching the network, the first network can be used as a priority network without affecting the call quality.

In any of the above embodiments, the second evaluation value is updated, and the second network is switched to the first network based on the updated second evaluation value, the second threshold and the second duration, so that the network of the electronic device is switched between the first network and the second network until the call ends.

As shown in FIG. 4 and FIG. 5 , the network switching method includes:

Step 402: The electronic device triggers a voice call under VoNR;

Step 404, determining whether the voice call under VoNR is ended at each interval of a time length TI, and if the determination result is yes, ending; if the determination result is no, executing step 406;

Step 406, detecting the MOS value of the voice call under VoNR;

Step 408, determining whether the MOS value of the voice call under VoNR is lower than the first threshold and maintained for the first duration, if the determination result is yes, executing step 410, if the determination result is no, executing step 406;

Step 410, switching the voice call under VoNR to the voice call under VoLTE;

Step 412, determining whether the voice call under VoLTE is ended at intervals of a time length T2, and if the determination result is yes, ending the call; if the determination result is no, executing step 414;

Step 414, detecting the MOS value of the voice call under VoLTE;

Step 416, determine whether the MOS value of the voice call under VoLTE is greater than or equal to the second threshold and is maintained for the second duration. If the judgment result is yes, execute step 402, and if the judgment result is no, execute step 414.

The AP may be an upper layer application module corresponding to a modem, wherein the instruction sent by the AP includes the switched network so that the modem feeds back ACK confirmation information (ie, the confirmation information mentioned above).

In any of the above embodiments, the call includes: a voice call or a video call.
