Description

Technical Field

[0001] The present application relates to the field of computer technology, and in particular to a voice call method, device, terminal and storage medium. Background Art

[0002] With the development of communication technology, many operators gradually support Vowifi (Voice over wifi, voice based on wireless fidelity). Through Vowifi, the terminal can initiate a voice call through the connected wireless network. Compared with VoNR (Voice over New Radio) and VoLTE (Voice over Long Term Evolution), which can only initiate voice calls through cellular networks, Vowifi reduces the terminal's dependence on cellular networks. Among them, VoNR and VoLTE will establish a dedicated bearer for voice calls. In the case of tight bandwidth resources, the data packets of voice calls can be stably transmitted through dedicated bearers, ensuring the quality of voice calls. However, Vowifi does not establish a dedicated bearer for voice calls. In the case of tight bandwidth resources, the data packets of voice calls compete with other data packets for bandwidth, and the data packets of voice calls cannot be transmitted in time, resulting in poor quality of voice calls. Therefore, how to improve the quality of voice calls established through Vowifi is a technical problem that needs to be solved urgently. Summary of the invention

[0014] A determination unit is used to determine the network quality of the wireless network based on the detection result, wherein the network quality is positively correlated with the signal strength, the network quality is negatively correlated with the retransmission rate, the network quality is negatively correlated with the packet loss rate, and the network quality is negatively correlated with the average delay.

[0015] In some embodiments, the determination unit is used to determine the detection score of each network parameter in the detection result based on the detection result, the detection score of the signal strength is positively correlated with the signal strength, the detection score of the retransmission rate is negatively correlated with the retransmission rate, the detection score of the packet loss rate is negatively correlated with the packet loss rate, and the detection score of the average delay is negatively correlated with the average delay; based on the weight of each network parameter, the detection score of each network parameter is weighted and summed to obtain the quality score of the wireless network, the quality score is used to reflect the network quality of the wireless network, and the quality score is positively correlated with the network quality of the wireless network.

[0016] In some embodiments, when the network quality of the wireless network is represented by the quality score, the quality threshold is a quality score threshold;

[0036] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0037] In this article, "at least one" means one or more, and "plurality" means two or more. "And / or" describes the association relationship of the associated objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0038] It should be noted that the information (including but not limited to user device information, user personal information, etc.), data (including but not limited to data used for analysis, stored data, displayed data, etc.) and signals involved in this application are all authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with the relevant laws, regulations and standards of the relevant countries and regions. For example, the priority information and data packets transmitted by the wireless network involved in this application are all obtained with full authorization.

[0039] Figure 1 is a schematic diagram of an implementation environment provided by an embodiment of the present application. Figure 1 The implementation environment includes a terminal 101 and a network device 102. The terminal 101 can communicate with the network device 102 directly or indirectly.

[0040] In some embodiments, the terminal 101 may be a mobile phone, a desktop computer, a laptop computer, a tablet computer, a smart watch, etc. Through the Vowifi (Voice over wifi, based on wireless fidelity) technology provided by the operator, the terminal 101 can access the operator's core network through the wireless network after connecting to the wireless network, thereby realizing service functions such as initiating voice calls and sending text messages through the core network.

[0041] In some embodiments, after the terminal 101 establishes a voice call through the Vowifi technology, the terminal 101 sends a data packet of the voice call to the network device 102 through the wireless network, or receives a data packet of the voice call sent by the network device 102 through the wireless network. Since the terminal 101 can also transmit data packets of other services through the wireless network. Therefore, in order to ensure the quality of the voice call, the terminal 101 increases the priority of the data packet of the voice call, ensures that the data packet of the voice call can be preferentially transmitted through the wireless network, thereby improving the call quality of the voice call.

[0042] In some embodiments, the network device 102 is a base station corresponding to at least one of the Long Term Evolution (LTE) system, the Wideband Code Division Multiple Access (WCDMA) system, or the Global System for Mobile Communications (GSM). In the embodiments of the present application, this is not specifically limited. In some embodiments, the network device 102 is any network device 102 with wireless transceiver functions. For example, the network device 102 is an evolved Node B (eNB), a next generation Node B (gNB), a wireless relay node, a wireless backhaul node, a transmission point (TP), or a transmission and reception point (TRP).

[0043] Figure 2 is a flow chart of a voice call method provided in an embodiment of the present application. The method is executed by a terminal, see Figure 2 , the method comprising:

[0044] 201. During a target voice call, the terminal determines the network quality of the wireless network. The target voice call is a voice call established through Vowifi based on wireless fidelity. The wireless network is used to transmit data packets of the target voice call. The data packets encapsulate voice data of the target voice call.

[0045] In the embodiment of the present application, the wireless network may be a wireless access point (AP) or a wireless hotspot. The wireless network is used to provide network connection services to devices such as terminals. After the terminal successfully connects to the wireless network, the terminal can transmit data with other terminals or servers through the wireless network.

[0046] For terminals that support Vowifi (Voice over wifi, voice based on wireless fidelity) technology, the terminal can also establish voice calls with other terminals through the wireless network, or send text messages to other terminals through the wireless network. For ease of description, the voice call established by the terminal through the Vowifi technology is referred to as the target voice call below. When the terminal successfully establishes the target voice call, the terminal transmits the data packet of the target voice call through the wireless network. For example, the terminal encapsulates the collected voice data into a data packet, and sends the data packet to the network device through the wireless network, and the network device forwards the data packet to the other end of the target voice call. Alternatively, the terminal receives a data packet sent by the network device through the wireless network, and the data packet encapsulates the voice data collected by the other end of the target voice call.

[0047] Since the terminal transmits the data packets of the target voice call through the wireless network, the network quality of the wireless network directly affects the call quality of the target voice call. In order to ensure the call quality of the target voice call, the terminal can determine the network quality of the wireless network by detecting the network status of the wireless network during the target voice call.

[0048] For example, the terminal can determine the network quality of the wireless network by detecting the signal strength, transmission rate and transmission bandwidth of the wireless network; the terminal can also determine the quality of the wireless network by detecting the retransmission rate and packet loss rate of the wireless network transmission data packet. The embodiment of the present application does not limit the specific method for the terminal to determine the network quality of the wireless network.

[0049] 202. When the network quality of the wireless network is lower than the quality threshold, the terminal increases the priority of the data packet of the target voice call from the first priority to the second priority.

[0050] In an embodiment of the present application, when the network quality of the wireless network is lower than the quality threshold, the network quality of the wireless network is poor, and the bandwidth resources of the wireless network are relatively tight. Since the terminal not only transmits the data packets of the target voice call through the wireless network, the terminal also transmits the data packets of other services through the wireless network. Therefore, when the network quality of the wireless network is poor, the data packets of other services and the data packets of the target voice call occupy the bandwidth resources, resulting in that the data packets of the target voice call cannot be transmitted in time, thereby reducing the call quality of the target voice call. Therefore, the terminal increases the priority of the data packets of the target voice call from the first priority to the second priority, so that the terminal can preferentially transmit the data packets of the target voice call through the wireless network. Among them, the quality threshold can be a value determined based on experience, such as 60, 70 or 80, which is not limited in the embodiment of the present application.

[0051] 203. The terminal transmits the data packet of the target voice call according to the second priority through the wireless network.

[0052] In an embodiment of the present application, after the terminal increases the priority of the data packet of the target voice call to the second priority, the terminal transmits the data packet of the target voice call with the higher second priority through the wireless network, thereby ensuring that the data packet of the target voice call can be transmitted in time. For other data packets with lower priorities, the terminal can maintain multiple data packets with lower priorities through a waiting queue. After the data packet of the target voice call with the current higher priority is transmitted, the terminal transmits the first data packet in the waiting queue through the wireless network, thereby avoiding the data packets of other services and the data packets of the target voice call from occupying bandwidth resources, and can ensure the call quality of the target voice call.

[0053] The embodiment of the present application provides a voice call method, in which when a terminal is connected to a wireless network and a voice call is established through Vowifi, the terminal can transmit data packets for the voice call through the wireless network. Since the terminal also transmits data packets for other services through the wireless network, when the network quality of the wireless network is poor, the data packets for other services will compete with the data packets for the voice call for the transmission bandwidth. Therefore, in order to ensure that the terminal can transmit the data packets for the voice call in a timely manner, the terminal increases the priority of the data packets for the voice call, and then the terminal can preferentially transmit the data packets for the voice call through the wireless network. The above method ensures that the data packets for the voice call can be sent out preferentially, thereby ensuring the call quality of the voice call.

[0054] Figure 3 is a flowchart of another voice call method provided in an embodiment of the present application. The method is executed by the terminal, see Figure 3 , the method comprising:

[0055] 301. During a target voice call, the terminal determines the network quality of the wireless network. The target voice call is a voice call established through Vowifi based on wireless fidelity. The wireless network is used to transmit data packets of the target voice call. The data packets encapsulate voice data of the target voice call.

[0056] In an embodiment of the present application, the wireless network may be a wireless access point (AP) or a wireless hotspot. The wireless network is used to provide network connection services to devices such as terminals. After the terminal successfully connects to the wireless network, the terminal can transmit data with other terminals or servers by using the network connection service provided by the wireless network. For terminals that support Vowifi (Voice over wifi, voice based on wireless fidelity) technology, the terminal can also access the operator's core network through the wireless network to implement service functions such as initiating voice calls and sending text messages. Among them, the core network that the terminal accesses through the wireless network may be a 4G core network provided by the operator, or a 5G core network provided by the operator, and this embodiment of the present application does not limit this. However, due to the different network element devices and network architectures of the 4G core network and the 5G core network. Therefore, the Vowifi architecture built by the operator based on the 4G core network or the 5G core network is also different. Among them, the Vowifi architecture is used to implement the Vowifi technology.

[0057] For example, Figure 4 A schematic diagram of a Vowifi architecture is shown in FIG. Figure 4 As shown, the Vowifi architecture is a Vowifi architecture built on the 4G core network. Through the Vowifi architecture, the terminal 401 can access the operator's 4G core network through the evolved packet data gateway (ePDG, evolevd Packet Data Gateway) and the PDN gateway (PGW, PDN Gateway) after connecting to the wireless network 402, thereby realizing functions such as initiating voice calls and sending text messages through the 4G core network.

[0058] For ease of description, the voice call established by the terminal through the Vowifi technology is referred to as the target voice call below. When the terminal successfully establishes the target voice call, the terminal transmits the data packet of the target voice call through the wireless network. For example, the terminal encapsulates the collected voice data into a data packet, and sends the data packet to the network device through the wireless network, and the network device forwards the data packet to the other end of the target voice call. Alternatively, the terminal receives a data packet sent by the network device through the wireless network, and the data packet encapsulates the voice data collected by the other end of the target voice call.

[0059] Since the terminal transmits the data packets of the target voice call through the wireless network, the network quality of the wireless network directly affects the call quality of the target voice call. In order to ensure the call quality of the target voice call, the terminal can determine the network quality of the wireless network by detecting the network status of the wireless network during the target voice call.

[0060] In some embodiments, the terminal can determine the network quality of the wireless network by detecting the network parameters of the wireless network. During the process of the terminal making a target voice call, the terminal detects the network parameters of the wireless network and obtains the detection result of the wireless network. The network parameters include at least one of signal strength, retransmission rate of data packets transmitted through the wireless network, packet loss rate of data packets transmitted through the wireless network, and average delay of connecting to a domain name server through the wireless network. Then, the terminal determines the network quality of the wireless network based on the detection result of the wireless network. The network quality is positively correlated with the signal strength, negatively correlated with the retransmission rate, negatively correlated with the packet loss rate, and negatively correlated with the average delay.

[0061] In some embodiments, the terminal may determine the signal strength of the wireless network by detecting the RSSI (Received Signal Strength Indication) of the wireless network. RSSI is used to indicate the signal strength of the wireless network received by the terminal. The higher the signal strength indicated by RSSI, the higher the signal strength of the wireless network; the lower the signal strength indicated by RSSI, the lower the signal strength of the wireless network.

[0062] In some embodiments, during the process of detecting the retransmission rate, the terminal may select any one of a plurality of transmission protocols of the wireless network, such as TCP (Transmission Control Protocol), RTP (Real-time Transport Protocol) or RTMP (Real-Time Messaging Protocol). Then, the terminal detects the retransmission rate of data packets transmitted through the wireless network using the transmission protocol. The retransmission rate refers to the ratio of the number of retransmitted data packets per unit time to the total number of sent data packets.

[0063] In some embodiments, when detecting the packet loss rate, the terminal may also select any one of a plurality of transmission protocols of the wireless network, and detect the packet loss rate of the terminal transmitting data packets through the wireless network using the transmission protocol. The packet loss rate refers to the ratio of the number of data packets lost per unit time to the total number of data packets sent.

[0064] In some embodiments, during the process of detecting the average delay, the terminal may connect to at least one domain name server through the wireless network, and determine the time consumed to connect to each domain name server. Then, the terminal determines the average value of the time consumed to connect to each domain name server as the average delay for the terminal to connect to the domain name server through the wireless network.

[0065] In some embodiments, the terminal can score the network quality of the wireless network based on the detection results of the wireless network. Based on the detection results, the terminal determines the detection score of each network parameter in the detection results. Among them, the detection score of signal strength is positively correlated with the signal strength, the detection score of retransmission rate is negatively correlated with the retransmission rate, the detection score of packet loss rate is negatively correlated with the packet loss rate, and the detection score of average delay is negatively correlated with the average delay. Then, based on the weight of each network parameter, the terminal performs weighted summation on the detection score of each network parameter to obtain the quality score of the wireless network. Among them, the quality score is used to reflect the network quality of the wireless network, and the quality score is positively correlated with the network quality of the wireless network.

[0066] In some embodiments, the terminal can quantize the network parameters according to the detected network parameters to obtain a detection score of the network parameters. Table 1 below shows a quantization rule. The terminal can determine the detection score of the network parameter according to the quantization rule. It should be noted that the terminal can also determine the detection score of the network parameter according to other quantization rules or in other ways, and the embodiments of the present application are not limited to this.

[0067] Table 1

[0068]

[0069] As shown in Table 1, when the signal strength is not less than -60dbm (decibel milliwatt), the terminal determines that the detection score of the signal strength is 90; when the signal strength is less than -60dbm and not less than -70dbm, the first terminal determines that the detection score of the signal strength is 80; when the signal strength is less than -70dbm and not less than -80dbm, the first terminal determines that the detection score of the signal strength is 70; when the signal strength is less than -80dbm, the first terminal determines that the detection score of the signal strength is 60.

[0070] For example, after the terminal detects the four network parameters of the wireless network, namely, signal strength, retransmission rate, packet loss rate and average delay, it is found that the signal strength of the wireless network is -70dbm, the retransmission rate is 3%, the packet loss rate is 4%, and the average delay is 15ms. Then, the terminal determines that the detection scores of the above four network parameters are all 80 according to the quantization rules shown in Table 1 above. Then, the terminal performs weighted summation of the detection scores of each network parameter according to the weight of each network parameter to obtain the quality score of the wireless network. When the weight of each network parameter is 0.25, the terminal determines that the quality score of the wireless network is 0.25*80+0.25*80+0.25*80+0.25*80=80.

[0071] In some embodiments, the terminal can process the detection result of the wireless network through a network quality scoring system to obtain a quality score of the wireless network. Figure 5 A schematic diagram of a network quality scoring system is shown in Figure 2. Figure 5 As shown, the network quality scoring system is used to determine the detection score of each network parameter in the detection result according to the quantification rule, and to perform weighted summation on the detection score of each network parameter according to the weight of the network parameter to obtain the quality score of the wireless network. Among them, the quantification rule and the weight of the network parameter can be set by the terminal in the network quality scoring system, or can be input into the network quality scoring system by the user, and the embodiment of the present application does not limit this.

[0072] 302. When the network quality of the wireless network is lower than the quality threshold, the terminal increases the priority of the data packet of the target voice call from the first priority to the second priority.

[0073] In the embodiment of the present application, after the terminal determines the network quality of the wireless network, it can determine whether the network quality of the wireless network is good by comparing the network quality and the quality threshold. When the network quality of the wireless network is lower than the quality threshold, it indicates that the network quality of the wireless network is poor and the bandwidth resources of the wireless network are relatively tight; when the network quality of the wireless network is not lower than the quality threshold, it indicates that the network quality of the wireless network is good and the bandwidth resources of the wireless network are sufficient. Since the terminal not only transmits the data packets of the target voice call through the wireless network, the terminal also transmits the data packets of other services through the wireless network. Therefore, when the network quality of the wireless network is poor, the data packets of other services and the data packets of the target voice call occupy the bandwidth resources, resulting in that the data packets of the target voice call cannot be transmitted in time, thereby reducing the call quality of the target voice call. Therefore, the terminal increases the priority of the data packets of the target voice call from the first priority to the second priority, so that the terminal can preferentially transmit the data packets of the target voice call through the wireless network. Among them, the quality threshold can be a value determined based on experience, such as 70, 80 or 90, which is not limited in the embodiment of the present application.

[0074] In some embodiments, when the terminal indicates the network quality of the wireless network by a quality score, the quality threshold is the quality score threshold. When the quality score of the wireless network is lower than the quality score threshold, the terminal increases the priority of the data packet of the target voice call from the first priority to the second priority. For example, when the quality score threshold is 90 and the quality score of the wireless network is 80, the terminal increases the priority of the data packet of the target voice call to the second priority.

[0075] In order to more clearly illustrate the process of the terminal increasing the priority of the data packet of the target voice call, the above process is described in the following three ways respectively.

[0076] Method 1: When the network quality of the wireless network is lower than the quality threshold, the terminal obtains priority information. The priority information is used to indicate the priority of multiple types of data packets transmitted by the wireless network. The terminal determines the target priority based on the priority information. The target priority is the highest priority in the priority information. The terminal determines the current priority of the data packet of the target voice call, that is, the size relationship between the first priority and the target priority. When the target priority is higher than the first priority, it indicates that there is currently a data packet with a priority higher than the first priority, and the wireless network gives priority to transmitting the above data packet. Therefore, the terminal determines the target priority as the second priority. The terminal increases the priority of the data packet of the target voice call from the first priority to the second priority, so that the data packet of the target voice call can be transmitted with the same priority as the above data packet.

[0077] For example, when the priority information includes 3, 4, and 5, and 3 is the highest priority in the priority information and 5 is the lowest priority in the priority information, the terminal determines the target priority to be 3. When the first priority is 4, the terminal determines the second priority to be 3, and increases the priority of the data packet of the target voice call from 4 to 3.

[0078] Mode 2: When the target priority is equal to the first priority, it indicates that the priority of the data packet of the target voice call is already the highest priority in the priority information. The terminal determines a priority that is at least one priority higher than the first priority as the second priority. The terminal increases the priority of the data packet of the target voice call from the first priority to the second priority.

[0079] For example, when the target priority is 3 and the first priority is also 3, the terminal determines the second priority to be 2, and the terminal increases the priority of the data packet of the target voice call from 3 to 2. Alternatively, the terminal determines the second priority to be 1, and the terminal increases the priority of the data packet of the target voice call from 3 to 1.

[0080] Method 3: When the network quality of the wireless network is lower than the quality threshold, the terminal determines the highest priority defined in the transmission protocol of the wireless network as the second priority. The terminal increases the priority of the data packet of the target voice call from the first priority to the second priority, so as to transmit the data packet of the target voice call with the highest priority through the wireless network.

[0081] For example, the transmission protocol of the wireless network defines 9 priorities from 1 to 9, where 1 is the highest priority and 9 is the lowest priority. When the network quality of the wireless network is lower than the quality threshold, the terminal increases the priority of the data packet of the target voice call to 1.

[0082] It should be noted that the terminal can not only adjust the priority of the data packets of the voice call during the target voice call, but also adjust the priority of the data packets transmitted by different bearers when establishing a voice call through VoNR (Voice over New Radio) or VoLTE (Voice over Long Term Evolution). Among them, when the terminal establishes a voice call through VoNR or VoLTE, the terminal will allocate a dedicated bearer for the voice call to transmit the data packets of the voice call through the dedicated bearer. Therefore, the terminal can determine the priority of the data packets transmitted by different bearers by adjusting the value of the QCI (QoS Class Identifier, a parameter used to identify the priority) of different bearers. Table 2 below shows the values ​​of the QCI of different bearers.

[0085]

[0086] Among them, the bearer types in Table 2 include dedicated bearers and default bearers. Dedicated bearers are bearers specially established to transmit specific types of data packets in order to meet the transmission requirements of data packets. Dedicated bearers can guarantee the minimum transmission bandwidth of data packets. When bandwidth resources are tight, dedicated bearers can also transmit data packets according to the minimum transmission bandwidth. Therefore, the bearer allocated by the terminal for voice calls is a dedicated bearer. The default bearer is a bearer established by default when the terminal accesses the core network. The default bearer is used to transmit some signaling and user data. The default bearer does not guarantee the minimum transmission bandwidth.

[0087] As can be seen from Table 2 above, the terminal can establish a dedicated bearer with a QCI of 1 for a voice call, and transmit the data packets of the voice call through the wireless network with a priority of 2. The terminal can also adjust the priority of the data packets transmitted by the dedicated bearer by adjusting the value of the dedicated bearer QCI.

[0088] 303. For any other data packet, if the priority of the other data packet is higher than the third priority, the terminal adjusts the priority of the other data packet to the third priority, the other data packet is a data packet other than the data packet of the target voice call, and the third priority is lower than the first priority.

[0089] In an embodiment of the present application, during a target voice call, in order to further improve the quality of the target voice call, the terminal determines the priority of other data packets other than the data packets of the target voice call. Then, the terminal determines that the highest priority of the above-mentioned other data packets is the third priority, and the third priority is lower than the first priority. In the case where the priority of any other data packet is higher than the third priority, the terminal adjusts the priority of the other data packet to the third priority. By further reducing the priority of other data packets, the tension of the bandwidth resources of the wireless network can be alleviated, so that the data packets of the target voice call can be transmitted through the wireless network using a larger transmission bandwidth, thereby improving the quality of the target voice call.

[0090] 304. The terminal transmits the data packets of the target voice call according to the second priority through the wireless network, and transmits the other data packets according to the third priority.

[0091] In an embodiment of the present application, after the terminal adjusts the priority of each data packet, the terminal transmits the data packet of the target voice call with a higher second priority through the wireless network, and transmits the above-mentioned other data packets with a lower third priority. For the data packet whose original priority is lower than the third priority, the terminal transmits the data packet through the wireless network according to its original priority. Through the above method, it can be ensured that the data packet of the target voice call can be preferentially transmitted by the wireless network. For other data packets with lower priorities, the terminal can maintain multiple data packets with lower priorities through a waiting queue. After the data packet transmission of the target voice call with a higher priority is completed, the terminal transmits the first data packet in the waiting queue through the wireless network. In the case of poor network quality of the wireless network, the above method avoids the data packets of other services and the data packets of the target voice call from occupying bandwidth resources, ensures the call quality of the target voice call, and improves the user's call experience.

[0092] The embodiment of the present application provides a voice call method, in which when a terminal is connected to a wireless network and a voice call is established through Vowifi, the terminal can transmit data packets for the voice call through the wireless network. Since the terminal also transmits data packets for other services through the wireless network, when the network quality of the wireless network is poor, the data packets for other services will compete with the data packets for the voice call for the transmission bandwidth. Therefore, in order to ensure that the terminal can transmit the data packets for the voice call in a timely manner, the terminal increases the priority of the data packets for the voice call, and then the terminal can preferentially transmit the data packets for the voice call through the wireless network. The above method ensures that the data packets for the voice call can be sent out preferentially, thereby ensuring the call quality of the voice call.

[0093] All the above optional technical solutions can be arbitrarily combined to form optional embodiments of the present application, which will not be described one by one here.
