[0002] In order to effectively solve the problem of voice call demand in residential areas and densely populated high-rise areas with weak cellular network coverage, the introduction of VoWiFi (full name: Voice over WiFi, WiFi voice call) has become an industry-recognized effective supplementary solution. It can seamlessly switch with VoLTE (Voice over LTE, long-term evolution voice bearer) / VoNR (voice over New Radio, new air interface voice bearer) to improve the user's voice call experience. At present, the strategy for switching from VoWiFi to VoLTE / VoNR is that the user terminal mainly compares the signal strength of the current WiFi network with the reference signal receiving power (RSRP) of the cellular LTE / NR network to determine whether the switching threshold is met. If it is met, it will switch, otherwise it will not switch.

[0003] However, WiFi networks are prone to high signal strength but poor network connectivity, which causes VoWiFi to be unable to switch to VoLTE / VoNR in a timely manner, resulting in the situation of being "stuck" on the WiFi network, seriously affecting the user's voice call experience.

[0064] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0065] The voice service switching method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. In the process of the user terminal executing the VoWiFi voice service, the voice service quality corresponding to each first unit time is determined according to the voice packet index of the RTP voice packet in at least one first unit time. The user terminal determines the first voice quality detection result of the user terminal according to the voice service quality corresponding to each first unit time; and when the first voice quality detection result is lower than the first detection result threshold, the voice service of the user terminal is switched from the VoWiFi voice service to the mobile network voice service.

[0066] Among them, the user terminal refers to the terminal device that is currently executing the VoWiFi voice service, which can be a smart terminal such as a mobile phone or a computer, or a smart wearable device such as a smart watch or a smart bracelet.

[0067] In one embodiment, Figure 2 is a flow chart of a voice service switching method provided in accordance with an embodiment of the present application, wherein the method is applied to Figure 1 Taking the user terminal in as an example, the method includes the following steps:

[0068] S201, in the process of executing the VoWiFi voice service on the user terminal, determining the voice service quality corresponding to each first unit time according to the voice packet index of the RTP voice packet in at least one first unit time.

[0069] Among them, the user terminal is currently a terminal device executing the VoWiFi voice service. VoWiFi voice service refers to a voice call service based on a WiFi network. The first unit duration refers to a pre-set unit time period. RTP voice packet refers to an RTP (Real-time Transport Protocol) voice packet transmitted during the VoWiFi voice service. Voice packet indicators refer to relevant indicators of RTP voice packets. In this application, the voice packet indicators include at least one of the voice packet size, the number of voice packets received, the average interval duration of the voice packet, the voice packet header content (i.e., the serial number contained in the 12 bytes of the header) and the voice packet timestamp. Voice service quality refers to the performance indicators of the VoWiFi voice service.

[0070] As an optional implementation of the embodiment of the present application, in the process of executing the VoWiFi voice service on the user terminal, the voice packet index of the RTP voice packet in each first unit time is input into a voice quality detection tool, and the voice quality detection tool determines the voice service quality corresponding to each first unit time. The voice quality detection tool includes but is not limited to a neural network model.

[0071] As another optional implementation of the embodiment of the present application, in the process of the user terminal executing the VoWiFi voice service, for each unit time, according to the voice packet index of the RTP voice packet in the first unit time, the index value of each voice index is determined, and the index value of each voice index is fused to obtain a comprehensive score, and the comprehensive score is used as the voice service quality corresponding to the first unit time. Among them, the voice index includes at least one of the voice packet size, the number of voice packets received, the average interval time of the voice packet, the content of the voice packet header (that is, the sequence number contained in the 12 bytes of the header) and the voice packet timestamp. The fusion processing method includes but is not limited to summation, weighted summation, etc.

[0072] As another optional implementation of the embodiment of the present application, in the process of executing the VoWiFi voice service on the user terminal, for each unit time, according to the voice packet index of the RTP voice packet in the first unit time, it is judged whether the RTP voice packet has problems such as incomplete reception, disorder, loss, etc. of poor WiFi network transmission quality, and based on the judgment result, the voice service quality corresponding to each first unit time is determined.

[0073] S202: Determine a first voice quality detection result of the user terminal according to the voice service quality corresponding to each first unit time length.

[0074] The first voice quality detection result refers to a quality evaluation result of the VoWiFi voice service detected based on the voice service quality corresponding to each first unit time length.

[0075] As an optional implementation of the embodiment of the present application, according to the voice service quality corresponding to each first unit time length, each voice service quality is fused and the fusion result is used as the first voice quality detection result of the user terminal. The fusion processing method includes but is not limited to one of summing, weighted summing, and multiplying.

[0076] S203: When the first voice quality detection result is lower than the first detection result threshold, the voice service of the user terminal is switched from the VoWiFi voice service to the mobile network voice service.

[0077] The mobile network voice service is a VoLTE (Voice over LTE) voice service or a VoNR (Voice over New Radio) voice service. The mobile network is an LTE (Long Term Evolution) network or an NR (New Radio) network.

[0078] As an optional implementation of the embodiment of the present application, when the first voice quality detection result is lower than the first detection result threshold, the voice service of the user terminal is switched from the VoWiFi voice service to the mobile network voice service.

[0079] As another optional implementation of the embodiment of the present application, when the first voice quality detection result is lower than the first detection result threshold and the network quality of the mobile network meets the threshold value, the voice service of the user terminal is switched from the VoWiFi voice service to the mobile network voice service. The network quality may be the signal strength of the reference signal of the mobile network or the signal receiving power of the reference signal.

[0080] Optionally, in this embodiment, when the first voice quality detection result is not lower than the first detection result threshold, the user terminal does not perform the switching operation of the VoWiFi voice service.

[0081] The above-mentioned voice service switching method, in the process of the user terminal executing the VoWiFi voice service, determines the voice service quality corresponding to each first unit time according to the voice packet index of the RTP voice packet in at least one first unit time. According to the voice service quality corresponding to each first unit time, determine the first voice quality detection result of the user terminal. When the first voice quality detection result is lower than the first detection result threshold, the voice service of the user terminal is switched from the VoWiFi voice service to the mobile network voice service. In the process of the user terminal executing the VoWiFi voice service, the present application can determine the voice service quality corresponding to each first unit time, and then determine the first voice quality detection result. And when the first voice quality detection result is lower than the first detection result threshold, the voice service of the user terminal is switched from the VoWiFi voice service to the mobile network voice service, that is, in the present application, the first voice quality detection result corresponding to the VoWiFi voice service is used to determine whether to switch the voice service, so that the voice service switching is more reasonable, effectively improving the user's voice call experience, and solving the existing problem of relying only on signal strength as a switching decision, which is easy to cause "hanging" in the WiFi network.

[0082] In one embodiment, in order to more accurately determine the first voice quality detection result, such as Figure 3 As shown, an optional implementation of S202 includes:

[0083] S301, determining a first number of first unit durations in which voice service quality is higher than a first quality threshold in each first unit duration, and a second number of first unit durations in which voice service quality is not higher than the first quality threshold in each first unit duration.

[0084] The first quality threshold refers to a boundary condition used to characterize whether the voice service quality meets a certain quality requirement. The first quantity refers to the number of first unit durations of voice service quality that is higher than the first quality threshold. The second quantity refers to the number of first unit durations of voice service quality that is not higher than the first quality threshold.

[0085] Optionally, in this embodiment, a quality difference counter can be used to determine the first number of first unit time periods in which the voice service quality is higher than the first quality threshold in each first unit time period, and the second number of first unit time periods in which the voice service quality is not higher than the first quality threshold in each first unit time period.

[0086] S302: Use the difference between the first number and the second number as a first voice quality detection result of the user terminal.

[0087] As an optional implementation of the embodiment of the present application, the second number is subtracted from the first number, and the difference is used as the first voice quality detection result of the user terminal.

[0088] Another optional implementation of the embodiment of the present application is to control the quality difference counter. When it is detected that the voice service quality in the first unit time is higher than the first quality threshold, the quality difference counter is controlled to be incremented by one. When it is detected that the voice service quality in the first unit time is not higher than the first quality threshold, the quality difference counter is controlled to be decremented by one. The final value is used as the first voice quality detection result of the user terminal.

[0089] In this embodiment, by determining the first number of first unit time lengths in which the voice service quality is higher than the first quality threshold in each first unit time length, and the second number of first unit time lengths in which the voice service quality is not higher than the first quality threshold in each first unit time length, and then using the difference between the first number and the second number as the first voice quality detection result of the user terminal, the first voice quality detection result can be determined more accurately.

[0090] In one embodiment, if Figure 4 As shown, an optional implementation of S203 includes:

[0091] S401, when a first voice quality detection result is lower than a first detection result threshold and the network quality of each mobile network does not meet a threshold value, select a target network from each mobile network according to the threshold value and the network quality of each mobile network.

[0092] The threshold value refers to a threshold condition used to determine whether the network quality of the mobile network meets a certain quality requirement. The target network refers to a network with better network quality selected from various mobile networks. The mobile network is an LTE network or an NR network.

[0093] In this embodiment, an optional implementation of selecting a target network from various mobile networks according to the threshold value and the network quality of each mobile network is to select a mobile network whose network quality is closest to the threshold value as the target network.

[0094] In this embodiment, another optional implementation method of selecting a target network from each mobile network according to the threshold value and the network quality of each mobile network is to determine the quality difference between the network quality of each mobile network and the threshold value. The mobile network corresponding to the smallest quality difference value is used as the target network. In this embodiment, an optional implementation method of determining the quality difference between the network quality of each mobile network and the threshold value is to obtain the effective duration of the RTP inactivity timer of the user terminal (i.e., the effective duration T of the RTP / RTCP Time-out). out); wherein the effective duration includes at least one first unit duration. Within the effective duration, the network quality of each mobile network within the first unit duration is obtained. The quality difference between the network quality of each mobile network within the first unit duration and the threshold value is determined.

[0095] It should be noted that when the present application detects that the network quality of each mobile network does not meet the threshold value, it obtains the effective duration of the RTP inactivity timer of the user terminal. The purpose is to complete the determination of the voice service switching result within the effective duration, for example, switching to the mobile network voice service or maintaining the VoWiFi voice service.

[0096] S402: Determine a second voice quality detection result of the user terminal.

[0097] The second voice quality detection result refers to another quality evaluation result of the VoWiFi voice service of the user terminal.

[0098] Optionally, in this embodiment, the voice service quality corresponding to each second unit time length is determined based on the voice packet index of the RTP voice packets in the third number of second unit time lengths. The fourth number of second unit time lengths in which the voice service quality is higher than the second quality threshold in each second unit time length, and the fifth number of second unit time lengths in which the voice service quality is not higher than the second quality threshold in each second unit time length are determined. The difference between the fourth number and the fifth number is used as the second voice quality detection result of the user terminal. Specifically, the quality difference counter is controlled to increase by one when it is detected that the voice service quality in the second unit time length is higher than the second quality threshold; when it is detected that the voice service quality in the second unit time length is not higher than the second quality threshold, the quality difference counter is controlled to decrease by one, and the final value obtained by the quality difference counter is used as the second voice quality detection result of the user terminal.

[0099] It should be noted that, when determining the first voice quality detection result, the number of the first unit durations required is a basic number, and on this basis, this embodiment also includes a method for determining a third number, which is as follows:

[0100] The added value is determined based on the minimum quality difference. The sum of the added value and the basic quantity is taken as the third quantity. Among them, the optional way to determine the added value based on the minimum quality difference is that each quality difference or difference range is corresponding to an added value, that is, a mapping relationship between each quality difference or difference range and the added value is stored, so the added value can be determined by the specific value of the minimum quality difference. Assuming that the basic quantity is M and the added value is n, the third quantity is M+n.

[0101] It should be noted that the second unit duration of this embodiment is also determined based on the first unit duration, as follows: Determine the increase value based on the minimum quality difference value. Determine the second unit duration based on the increase value and the first unit duration. Exemplarily, the sum of the increase value and the first unit duration can be used as the second unit duration. For example, if the first unit duration is T m , then the second unit duration is T m+n ; Wherein, n is the increase value. The method for determining the increase value according to the minimum mass difference in this embodiment is described in detail in the above embodiment and will not be repeated here.

[0102] Optionally, in this embodiment, the second quality threshold can be determined according to the added value. An optional implementation is to determine the second quality threshold according to the added value and the quality threshold list; wherein the quality threshold list records the mapping relationship between each added value and the corresponding quality threshold. Another optional implementation is to determine the target difference according to the added value. The fusion result of the target difference and the first quality threshold is used as the second quality threshold. The fusion method can be any one of difference calculation, summation, and weighted summation. An optional implementation method for determining the target difference according to the added value is to determine the target difference according to the added value by table lookup.

[0103] S403: When the second voice quality detection result is lower than the second detection result threshold, the voice service of the user terminal is switched from the VoWiFi voice service to the target network voice service.

[0104] Optionally, in this embodiment, when the second voice quality detection result is lower than the second detection result threshold, the network quality of the target network is detected in real time, and the timing of triggering the switching is dynamically adjusted. When it is detected that the target network meets the threshold value, the voice service of the user terminal is switched from the VoWiFi voice service to the target network voice service.

[0105] Optionally, in this embodiment, when the second voice quality detection result is not lower than the second detection result threshold, the user terminal does not perform the VoWiFi voice service switching operation and still stays in the VoWiFi voice service.

[0106] In this embodiment, when the first voice quality detection result is lower than the first detection result threshold and the network quality of each mobile network does not meet the threshold value, the target network is selected from each mobile network according to the threshold value and the network quality of each mobile network. The second voice quality detection result of the user terminal is determined. When the second voice quality detection result is lower than the second detection result threshold, the voice service of the user terminal is switched from the VoWiFi voice service to the target network voice service, which effectively ensures that the voice service can be maintained in a better network and effectively guarantees the user's voice call service experience.

[0107] In one embodiment, if Figure 5 As shown, another optional implementation of a voice service switching method includes:

[0108] S501, in the process of executing the VoWiFi voice service on the user terminal, according to the voice packet indicators of the RTP voice packets in the basic number of first unit time lengths, determine the voice service quality corresponding to each first unit time length. The voice packet indicators include the voice packet size, the number of voice packets received, the average interval time of the voice packets, the content of the voice packet header and the voice packet timestamp.

[0109] S502: Determine a first number of first unit durations in which voice service quality is higher than a first quality threshold, and a second number of first unit durations in which voice service quality is not higher than the first quality threshold.

[0110] S503: Use the difference between the first number and the second number as a first voice quality detection result of the user terminal.

[0111] S504: When the first voice quality detection result is lower than the first detection result threshold and the network quality of the mobile network meets the threshold value, the voice service of the user terminal is switched from the VoWiFi voice service to the mobile network voice service. The mobile network is an LTE network or an NR network; and the mobile network voice service is a VoLTE voice service or a VoNR voice service.

[0112] S505: When the first voice quality detection result is lower than the first detection result threshold and the network quality of each mobile network does not meet the threshold, obtain the effective duration of the RTP inactivity timer of the user terminal, wherein the effective duration includes at least one first unit duration.

[0119] S512: Determine a second unit duration according to the increased value and the first unit duration.

[0120] S513: Determine the voice service quality corresponding to each second unit time length according to the voice packet indicators of the RTP voice packets in the third number of second unit time lengths.

[0121] S514, determine a fourth number of second unit time periods in which the voice service quality is higher than the second quality threshold, and a fifth number of second unit time periods in which the voice service quality is not higher than the second quality threshold.

[0122] S515: Use the difference between the fourth number and the fifth number as a second voice quality detection result of the user terminal.

[0123] S516: When the second voice quality detection result is lower than the second detection result threshold, the voice service of the user terminal is switched from the VoWiFi voice service to the target network voice service.

According to the voice service quality corresponding to each first unit time length, the first voice quality detection result of the user terminal is determined. When the first voice quality detection result is lower than the first detection result threshold, the voice service of the user terminal is switched from the VoWiFi voice service to the mobile network voice service. In the process of the user terminal executing the VoWiFi voice service, the present application can determine the voice service quality corresponding to each first unit time length, and then determine the first voice quality detection result.
