Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It is to be noted that the terms "comprises" and "comprising" and any variations thereof in the examples and figures of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

It will be understood that, as used herein, the terms "first," "second," and the like may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another. For example, a first value can be termed a second value, and, similarly, a second value can be termed a first value, without departing from the scope of the present application. Both the first and second values are user satisfaction values, but they are not the same user satisfaction value. It is noted that the term "plurality" as used herein refers to two or more.

In the description of VoWiFi by 3GPP (3rd Generation Partnership Project), a UE (User Equipment) is connected to an ePDG (evolved Packet Data Gateway) through a Wi-Fi access network, and a voice service QoS (Quality of Experience) is not specified by 3GPP on the UE-to-ePDG segment. Therefore, the transmission performance of voice service data between the UE and the ePDG is not guaranteed, and the QoS of the voice service depends on the transmission performance of the segment of network to a large extent.

In the current VoWiFi network selection technical scheme, whether a UE selects a certain wireless access point to access a Wi-Fi network generally adopts the following criteria: the signal strength of the AP exceeds an access threshold set by the network operator, for example, the access threshold is-65 dBm (decibel relative to one milliwatt). As shown in fig. 1, the terminal device 1 searches for AP1, the signal strength of AP1 is-68 dBm, which is lower than the access threshold, and after the terminal device 1 connects to AP1, the terminal device 1 can access the Internet through ISP (Internet Service Provider) 1, but the terminal device 1 does not initiate the VoWiFi IMS registration. The terminal device 2 searches the AP1, the signal strength of the AP1 is-55 dBm and is higher than the access threshold value, after the terminal device 2 is connected with the AP1, the terminal device accesses the Internet through the ISP1, then is connected with the ePDG and initiates VoWiFi IMS registration, and accesses the IMS Core through the EPC (Evolved Packet Core, 4G Core network), so that the VoWiFi voice service can be carried out.

In the current technical scheme of VoWiFi network selection, when the UE executes Wi-Fi network access judgment, the UE only takes the WiFi signal intensity of the AP as a judgment standard, and finally selects the AP with the highest signal intensity to access the Wi-Fi network. For example, the terminal device 3 in fig. 1 searches for AP1 and AP2, the signal strength of AP1 is-55 dBm, the signal strength of AP2 is-52 dBm, the signal strengths of both APs are higher than the access threshold value, and after selecting the AP2 with the highest connection signal strength, the terminal device 3 accesses the internet through ISP2, connects an ePDG, and initiates a VoWiFi IMS registration.

However, since the network transmission performance of different internet service providers is different, the traffic busy degree of each AP is different, and the network performance from the UE to the ePDG segment is estimated only according to the signal strength of the AP, which may cause the UE to misjudge the voice service quality of the VoWiFi of the AP, and easily cause the situation of poor voice service quality, which affects voice communication. For example, the terminal device 3 in fig. 1 searches for the AP1 and the AP2, and after statistics of three dimensions, i.e., packet loss rate, delay, and jitter, of a downlink end-to-end voice data packet, the network performance of the ISP1 is better than that of the ISP2, but according to the current VoWiFi network selection technical scheme, the terminal device 3 selects the AP2 with higher signal strength to access the ISP2 network, so that the terminal device 3 cannot obtain an optimal voice service when using a VoWiFi call.

The embodiment of the application provides a wireless access point selection method, a wireless access point selection device, terminal equipment and a storage medium, which can improve the voice service quality of VoWiFi and improve the voice communication stability.

Fig. 2 is a diagram illustrating an exemplary embodiment of a wireless access point selection method. As shown in fig. 2, the terminal device 20 may be referred to as a User Equipment (UE). The terminal device 20 may be a Personal Communication Service (PCS) phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), or the like, and may also be a mobile phone, a Mobile Station (MS), a terminal device (mobile terminal), a notebook computer, or the like, and the terminal device 20 may communicate with one or more core networks through a Radio Access Network (RAN). For example, the terminal equipment 20 may be a mobile telephone (or so-called "cellular" telephone) or a computer having terminal equipment, etc., and the terminal equipment 20 may also be a portable, pocket, hand-held, computer-included, or vehicle-mounted mobile device that exchanges voice and/or data with the radio access network, for example. The terminal device 20 may also be a handheld device with a wireless communication function, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a network evolved in the future, and the like, and the implementation of the present application is not limited.

The terminal device 20 may obtain wireless access points existing around, such as the wireless access point 1, the wireless access point 2, the wireless access point 3, and the like shown in fig. 2, and if the signal strength of at least two first wireless access points is greater than the strength threshold, the terminal device 20 may select a target wireless access point from the at least two first wireless access points according to the selection probability corresponding to each first wireless access point. The selection probability corresponding to each first wireless access point is determined according to the voice quality metric value corresponding to each time the terminal device 20 selects the first wireless access point to access the wireless network.

For example, if the signal strengths corresponding to the wireless access point 1, the wireless access point 2, and the wireless access point 3 existing around the terminal device 20 are-70 dBm, -55dBm, and-53 dBm, respectively, and the strength threshold is-65 dBm, the wireless access point 2 and the wireless access point 3 having the signal strengths higher than the strength threshold exist, and the terminal device 20 can select a target wireless access point from the wireless access points 2 and 3 based on the selection probabilities corresponding to the wireless access points 2 and 3. The selection probability corresponding to the wireless access point 2 is determined according to the voice quality metric value corresponding to each time the terminal device 20 selects the wireless access point 2 to access the Wi-Fi network, and the selection probability corresponding to the wireless access point 3 is determined according to the voice quality metric value corresponding to each time the terminal device 20 selects the wireless access point 3 to access the Wi-Fi network. The terminal device 20 can access the wireless network through the selected target wireless access point and perform the VoWiFi IMS registration.

As shown in fig. 3, in one embodiment, a wireless access point selection method is provided, which is applicable to the terminal device described above, and the method may include the following steps:

in step 310, wireless access points existing around the terminal device are acquired.

The terminal device may scan wireless Access points existing within a certain range around (e.g., within 100 meters, within 50 meters, etc.), and acquire Access point information of each scanned wireless Access point, where the Access point information may include, but is not limited to, information such as an Access point Identifier and signal strength of the wireless Access point, where the Access point Identifier may be used to identify each wireless Access point, and the Access point Identifier may include, but is not limited to, any one of an Access point name, a Media Access Control (MAC) address of the wireless Access point, an Access point account number, an SSID (Service Set Identifier), and the like.

Optionally, the terminal device may scan the wireless access points existing around in real time, or may periodically scan the wireless access points existing around according to a preset scanning period (e.g., a scanning period of 5 minutes, 10 minutes, etc.).

As an embodiment, the terminal device may scan for wireless access points existing around when detecting that a switching condition for switching from the current first network call mode to the VoWiFi mode is satisfied. The first network communication mode may correspond to a different communication network, and optionally, the first network communication mode may include any one of a VoLTE mode and a VoNR mode, where VoLTE is a service supporting voice communication over an LTE (long term evolution) network, and VoNR is a service supporting voice communication over an NR (New Radio) network.

The switching condition for switching from the current first network call mode to the VoWiFi mode may be set according to implementation requirements, and optionally, the switching condition may include, but is not limited to, one or more of the following conditions:

and under the condition I, the terminal equipment enters an indoor scene from an outdoor scene. When the terminal device detects that the outdoor scene enters the indoor scene, namely the terminal device determines that the switching condition for switching from the current first network conversation mode to the VoWiFi mode is met, the terminal device can scan the wireless access points existing around. The method for the terminal device to detect that the terminal device enters the indoor scene from the outdoor scene is not limited herein, for example, the terminal device may acquire the signal strength of a satellite received by a GPS (Global Positioning System), and if the signal strength of the satellite received by the GPS is smaller than a preset received signal strength, it may be determined that the terminal device enters the indoor scene from the outdoor scene; alternatively, the terminal device may also obtain the positioning accuracy of the GPS, and if the positioning accuracy is smaller than a preset accuracy threshold, it may be determined that the terminal device enters an indoor scene from an outdoor scene, but the present invention is not limited thereto.

And a second condition is that the network signal of the first network to which the first network call mode belongs is degraded. If the first network call mode is the VoLTE mode, the first network may be an LTE network, and if the first network call mode is the VoNR mode, the first network may be an NR network. The terminal equipment can acquire the network signal intensity of a first network to which the current first network call mode belongs in real time, if the network signal intensity of the first network is detected to be lower than the preset intensity, the network communication mode needs to be switched, the switching condition of switching from the current first network call mode to the VoWiFi mode can be determined to be met, and the wireless access points existing around can be scanned.

Step 320, if the signal strength of at least two first wireless access points is greater than the strength threshold, selecting a target wireless access point from the at least two first wireless access points according to the selection probability corresponding to each first wireless access point; the selection probability corresponding to each first wireless access point is determined according to the voice quality metric value corresponding to each time the terminal equipment selects the first wireless access point to access the wireless network.

After the terminal device obtains the wireless access points existing around, it can judge whether the signal strength of each wireless access point is greater than the strength threshold value, and the wireless access point with the signal strength greater than the strength threshold value is taken as the first wireless access point. The strength threshold may be an access threshold set by a network operator, where the access threshold can be used to access a Wi-Fi network and perform a VoWiFi IMS registration, for example, the strength threshold may be-65 dBm, -60dBm, -67dBm, and the like, and the strength threshold may be set by the network operator according to actual network operation requirements. If the signal intensity of the wireless access point is greater than the intensity threshold value, it can be shown that the terminal device is connected with the wireless access point and accesses the Wi-Fi network, and the VoWiFi IMS registration can be normally performed.

The method can judge whether the number of the first wireless access points with the signal intensity larger than the intensity threshold is larger than 1, if the number of the first wireless access points with the signal intensity larger than the intensity threshold is only 1, the terminal equipment can take the first wireless access points as target wireless access points, access a wireless network through the target wireless access points, and perform VoWiFi IMS registration.

If the number of the first wireless access points with the signal strength greater than the strength threshold value is greater than 1, the target wireless access point can be selected from all the first wireless access points. The selection probability corresponding to each first wireless access point can be determined, and the target wireless access point is selected according to the selection probability corresponding to each first wireless access point, the higher the selection probability of the first wireless access point is, the higher the probability of being selected as the target wireless access point is, and the sum of the selection probabilities corresponding to each first wireless access point can be 1. For example, AP1, AP2 and AP3 exist around the terminal device, wherein the signal strengths of AP1, AP2 and AP3 are all greater than the strength threshold, the selection probabilities (e.g., 20%, 70% and 10% respectively) corresponding to AP1, AP2 and AP3 can be determined, where the selection probability of AP2 is the highest, and the probability of being selected as the target wireless access point is also the highest.

In this embodiment of the present application, the selection probability corresponding to each first wireless access point is determined according to a voice quality metric value corresponding to each time the terminal device selects the first wireless access point to access the wireless network. The terminal equipment can establish a voice quality database, evaluate and store the voice quality metric value when the wireless access point is connected each time, the voice quality metric value can be used for representing the voice service quality, and the higher the voice quality metric value is, the better the voice service quality is represented. Alternatively, the voice quality metric may be determined according to a plurality of network performance parameters, which may include, but are not limited to, voice data packet transmission delay, voice data packet loss rate, voice data packet jitter, equivalent delay, etc., and the voice quality metric may comprehensively reflect the network transmission performance.

The terminal equipment can dynamically adjust the selection probability of the wireless access point by synthesizing the voice quality metric value corresponding to each time the wireless access point is selected to access the wireless network, so as to obtain the optimal selection strategy of the wireless access point, and ensure that the terminal equipment can select the wireless access point with the optimal voice service quality with higher probability when the terminal equipment selects the target wireless access point each time.

As an embodiment, the selection probability corresponding to each first wireless access point may be in a positive correlation with the number of times that the voice quality metric value corresponding to the terminal device when selecting the first wireless access point to access the wireless network is greater than the quality threshold, that is, when the terminal device selects the first wireless access point to access the wireless network, the number of times that the corresponding voice quality metric value is greater than the quality threshold is greater, and the selection probability corresponding to the first wireless access point is higher. Wherein the voice quality metric being greater than the quality threshold may indicate that the user is satisfied with the voice communication service, and the voice service quality is excellent.

For example, AP1, AP2, and AP3 exist around the terminal device, where the signal strengths of AP1, AP2, and AP3 are all greater than the strength threshold, the number of times that the voice quality metric value corresponding to the terminal device when connecting to the AP1 to access the wireless network is greater than the quality threshold is 3 times, the number of times that the voice quality metric value corresponding to the terminal device when connecting to the AP2 to access the wireless network is greater than the quality threshold is 8 times, and the number of times that the voice quality metric value corresponding to the terminal device when connecting to the AP3 to access the wireless network is greater than the quality threshold is 5 times, then the selection probability of AP2 may be greater than the selection probability of AP3, and the selection probability of AP3 may be greater than the selection probability of AP 1.

As another embodiment, the selection probability corresponding to each first wireless access point may be in a positive correlation with the probability that the voice quality metric value corresponding to the terminal device when selecting the first wireless access point to access the wireless network is greater than the quality threshold, that is, when the terminal device selects the first wireless access point to access the wireless network, the probability that the corresponding voice quality metric value is greater than the quality threshold is higher, and the selection probability corresponding to the first wireless access point is higher. For example, AP1, AP2, and AP3 exist around the terminal device, where the signal strengths of AP1, AP2, and AP3 are all greater than the strength threshold, the probability that the voice quality metric value corresponding to the terminal device when the terminal device connects to AP1 and accesses to the wireless network is greater than the quality threshold is 50%, the probability that the voice quality metric value corresponding to the terminal device when the terminal device connects to AP2 and accesses to the wireless network is greater than the quality threshold is 80%, and the probability that the voice quality metric value corresponding to the terminal device when the terminal device connects to AP3 and accesses to the wireless network is greater than the quality threshold is 20%, then the selection probability of AP2 may be greater than the selection probability of AP1, and the selection probability of AP1 may be greater than the selection probability of AP 2. By adopting the method to determine the selection probability corresponding to each first wireless access point, the terminal equipment can be ensured to select the wireless access point with the optimal voice service quality with higher probability when selecting the target wireless access point each time.

In some embodiments, if the signal strength of each wireless access point around the terminal device is less than the strength threshold, the terminal device may randomly select one wireless access point to connect to the Wi-Fi network, or may select the wireless access point with the strongest signal strength to access to the Wi-Fi network, but may not initiate the VoWiFi IMS registration. And selecting the target wireless access point for connection from the condition that the signal intensity is greater than the intensity threshold value, so that the success rate of VoWiFi IMS registration can be ensured, and the condition of registration failure is avoided.

And step 330, accessing the wireless network through the target wireless access point, and performing VoWiFi IMS registration.

The terminal equipment can be connected with a target wireless access point, access to a Wi-Fi network through the target wireless access point, then connect with an ePDG and initiate VoWiFi IMS registration. After the VoWiFi IMS registration is successful, the voice communication can be carried out by using the VoWiFi mode. It should be noted that, for a specific registration manner of the VoWiFi IMS registration, reference may be made to relevant specifications in the communication standard, and details are not described herein again.

In the embodiment of the application, the selection probability of the wireless access point can be dynamically adjusted according to the voice quality metric value corresponding to each time the terminal equipment selects the wireless access point to access the wireless network, so that the terminal equipment can more easily select the wireless access point with better and more stable voice quality to access the wireless network and perform VoWiFi IMS registration, the voice service quality of VoWiFi can be improved, and the voice communication stability can be improved.

As shown in fig. 4A, in another embodiment, a wireless access point selection method is provided, which is applicable to the terminal device described above, and the method may include the following steps:

step 402, acquiring wireless access points existing around the terminal device.

The description of step 402 can refer to the description of step 310 in the above embodiments, and is not repeated here.

Step 404, if the signal strength of at least two first wireless access points is greater than the strength threshold, obtaining an access point score corresponding to each first wireless access point, where the access point score corresponding to each first wireless access point is determined according to the voice quality metric value corresponding to each time the terminal device selects the first wireless access point to access the wireless network.

The terminal device can calculate the access point score corresponding to the wireless access point according to the voice quality metric value corresponding to each time the wireless access point is selected to access the wireless network, the access point score corresponding to the wireless access point can be a dynamically changing value, and the access point score can be dynamically adjusted according to the network transmission performance of each time the wireless access point is accessed.

The following first describes a calculation method of the access point score corresponding to the wireless access point.

After the terminal equipment is accessed to the wireless access point, the voice quality metric value corresponding to each voice call in the process of accessing the wireless access point can be determined. Optionally, a plurality of network performance parameters in each voice call process may be acquired, and a voice quality metric corresponding to each voice call may be calculated according to the plurality of network performance parameters.

As a specific implementation manner, the voice quality metric may be evaluated according to a downlink network performance parameter during each voice call based on an E-Model simplified Model, where the network performance parameter may include downlink voice data packet transmission delay, downlink voice data packet loss rate, downlink voice data packet jitter, and the like. For each voice call, the equivalent delay can be calculated according to the transmission delay of the downlink voice data packet and the jitter of the downlink voice data packet in the voice call process, the initial voice quality metric value is calculated according to the equivalent delay, and the initial voice quality metric value is corrected according to the packet loss rate of the downlink voice data packet, so that the voice quality metric value corresponding to the voice call is obtained. Further, the voice quality metric corresponding to each voice call can be obtained by using the following formulas (1) to (3):

effective _ latency +2 jitter +10 formula (1)

R＝R ₀ -2.5 packet _ loss equation (3);

wherein latency represents the transmission delay of the downlink voice data packet, jitter represents the jitter of the downlink voice data packet, effective _ latency represents the equivalent delay, R ₀ And representing an initial voice quality metric, packet _ loss representing the packet loss rate of the downlink voice data packet, and R representing the voice quality metric. The voice quality metric may be used to characterize the satisfaction degree of the user's experience with respect to the voice communication service, and as an embodiment, the corresponding relationship between the voice quality metric, the MOS (Mean Opinion Score) and the satisfaction degree of the user's experience may refer to table 1:

TABLE 1

User experience satisfaction	Voice quality metric	MOS
			Is very satisfactory	90-100	4.3-5.0
Satisfaction	80-90	4.0-4.3
			Partial user satisfaction	70-80	3.6-4.0
A lot of user dissatisfaction	60-70	3.1-3.6
			Almost all users are dissatisfied	50-60	2.6-3.1
Is not recommended	0-50	1.0-2.6

As can be seen from table 1, the higher the speech quality metric, the greater the user experience satisfaction. It should be noted that table 1 only shows one of the corresponding relations among the voice quality metric, the MOS, and the user experience satisfaction, and the numerical values in table 1 are only used to illustrate the corresponding relations among the three, and are not used as specific limitations.

The terminal device can determine the average value of the voice quality corresponding to the wireless access point, and after each voice call is finished, the terminal device can update the data in the voice quality database. The average value of the voice quality corresponding to the access wireless access point can be updated according to the voice quality metric value corresponding to the voice call and the voice call times in the process of accessing the wireless access point. Specifically, formula (4) may be adopted to update the average voice quality value corresponding to the current access point:

R(AP _n )＝(R(AP _n )′*N _c (AP _n )′+R)/(N _c (AP _n ) ' +1) formula (4);

wherein, AP _n Radio access point, R (AP), representing this access _n ) ' represents the voice quality average value updated last time, R represents the voice quality metric value corresponding to the voice call, N _c (AP _n ) ' indicates the last updated number of voice calls, R (AP) _n ) Representing the average value of the voice quality of the current update. After the average value of the voice quality is updated, the voice call times can be updated, N _c (AP _n )＝N _c (AP _n )′+1，N _c (AP _n ) I.e. the updated voice call times.

After the voice quality average value corresponding to the wireless access point accessed by the terminal equipment at this time is determined, the user satisfaction value corresponding to the wireless access point accessed at this time can be determined according to the voice quality average value, and the access point score corresponding to the wireless access point is updated according to the user satisfaction value corresponding to the wireless access point accessed at this time.

In some embodiments, when detecting that the wireless access point is disconnected from the current access, that is, when ending the current access to the wireless network through the wireless access point, the terminal device may determine a user satisfaction value corresponding to the current access to the wireless access point according to the voice quality average value, and update the access point score corresponding to the wireless access point according to the user satisfaction value corresponding to the current access to the wireless access point. The disconnection of the terminal device from the currently accessed wireless access point may include the following situations:

in a first case, the terminal device switches from the wireless access point accessed this time to another wireless access point to access the wireless network, for example, the wireless access point accessed this time by the terminal device is AP1, and when it is detected that the Wi-Fi network is connected by switching from AP1 to AP2, it is determined that the access to the Wi-Fi network through AP1 this time is ended.

And in the second case, the terminal equipment is switched from the Wi-Fi network to other types of networks, for example, the terminal equipment is switched from the Wi-Fi network to the LTE network or from the Wi-Fi network to the NR network, and the like.

As an implementation manner, the terminal device may compare a voice quality average value corresponding to the current access to the wireless access point with a quality threshold, and if the voice quality average value is greater than or equal to the quality threshold, may determine that a user satisfaction value corresponding to the current access to the wireless access point is a first value, and if the voice quality average value is less than the quality threshold, may determine that the user satisfaction value corresponding to the current access to the wireless access point is a second value, where the first value may be greater than the second value. The quality threshold may refer to a threshold value at which the user is satisfied with the voice communication service traffic, for example, the quality threshold may be 80 in table 1, etc., but is not limited thereto. The first value and the second value may be set according to actual requirements, for example, the first value may be 1, the second value may be 0, and the like, but not limited thereto.

After the terminal equipment determines the user satisfaction value corresponding to the wireless access point, the access point score corresponding to the wireless access point can be updated according to the user satisfaction value. Optionally, it may be determined whether an access frequency corresponding to the wireless access point is greater than 1, where the access frequency may refer to a frequency of connecting the terminal device to the wireless access point. If the access frequency corresponding to the wireless access point is not more than 1 but equal to 1, that is, it indicates that the terminal device is connected to the wireless access point this time is the first connection, the user satisfaction value corresponding to the wireless access point this time can be directly determined as the access point score corresponding to the wireless access point. If the access times corresponding to the wireless access point is more than 1, determining a change score according to the user satisfaction value corresponding to the access of the current time and the access point score updated last time of the wireless access point, and accumulating the access point score updated last time of the wireless access point and the change score to obtain the access point score updated this time of the wireless access point.

As a specific embodiment, the access point score corresponding to the wireless access point can be updated by using equation (5):

wherein, AP _n Radio access point, S (AP), representing this access _n ) Represents the user satisfaction value, Q (AP), corresponding to the access point of the current time _n ) _new Indicates the access point score, Q (AP), of this update _n ) _old Represents the last updated access point score, N, for that wireless access point _s (AP _n ) The access times corresponding to the wireless access point.

Exemplarily, taking the case that the terminal device is connected to the AP1 and accesses the Wi-Fi network through the AP1 to perform the VoWiFi service, in the process that the terminal device connects to the AP1 this time, when the terminal device performs a voice call each time, the voice quality metric value may be evaluated according to the downlink network performance parameter in the voice call process, and after the voice call is ended, the voice quality average value corresponding to the AP1 that the terminal device connects to this time is updated according to the voice quality metric value corresponding to the voice call. When the terminal device disconnects from the AP1, the user satisfaction value corresponding to the AP1 of the current connection may be determined according to the voice quality average value corresponding to the AP1 of the current connection of the terminal device, and the access point score corresponding to the AP1 may be updated according to the user satisfaction value. By adopting the mode, after the terminal equipment accesses Wi-Fi through the wireless access point and performs the VoWiFi service, the voice quality database can be updated, the access point score corresponding to the accessed wireless access point is dynamically adjusted, the selection strategy of the terminal equipment for each wireless access point is adaptively adjusted based on a reinforcement learning algorithm, and the auxiliary terminal equipment can more easily select the wireless access point with better voice quality and more stable to perform the VoWiFi service.

Step 406, determining the selection probability corresponding to each first wireless access point according to the historical access times of each first wireless access point and the corresponding access point score.

Under the condition that the signal intensity of at least two first wireless access points around the terminal equipment is greater than the intensity threshold value, the access point score corresponding to each first wireless access point can be obtained from the voice quality quantity library, and the selection probability corresponding to each first wireless access point is calculated according to the historical access times of each first wireless access point and the corresponding access point score. As a specific embodiment, the selection probability corresponding to each first radio access point can be calculated by using formula (6) and formula (7):

wherein, Q (AP) _n ) Indicating a first wireless access point AP _n Corresponding access point score, P (AP) _n ) Indicating a first wireless access point AP _n Corresponding selection probability, N _s (AP _n ) Indicating a first wireless access point AP _n The corresponding number of historical accesses, T is a calculation coefficient, and N is the number of first wireless access points, for example, if there are 3 first wireless access points around the terminal device, N is 3, and if there are 2 first wireless access points around the terminal device, N is 2. The terminal device may accumulate the historical access times corresponding to each first wireless access point, determine a calculation coefficient according to the accumulated result, and perform normalization calculation according to the calculation coefficient and the access point score corresponding to each first wireless access point to obtain the selection probability corresponding to each first wireless access point, where the sum of the selection probabilities corresponding to each first wireless access point may be 1.

Step 408, selecting a target wireless access point from the at least two first wireless access points according to the selection probability corresponding to each first wireless access point.

After the selection probability corresponding to each first wireless access point is determined, the terminal equipment can randomly select a target wireless access point from each first wireless access point to access the Wi-Fi network according to the selection probability corresponding to each first wireless access point, and perform VoWiFi IMS registration.

And step 410, accessing the wireless network through the target wireless access point, and performing VoWiFi IMS registration.

In some embodiments, after the terminal device accesses the wireless network through the target wireless access point and performs the VoWiFi IMS registration, the voice quality database may be updated according to the network transmission performance of the current access to the target wireless access point. In the process of accessing the wireless network through the target wireless access point, the voice quality metric value corresponding to each voice call can be determined, and further, the voice quality metric value corresponding to each voice call can be determined according to the above formula (1) to formula (3).

And determining a user satisfaction value corresponding to the current access to the target wireless access point according to the voice quality metric value corresponding to each voice call. Optionally, when it is detected that the terminal device is switched from the target wireless access point to another wireless access point to access the wireless network, or when it is detected that the terminal device is switched from the Wi-Fi network to another type of network, the user satisfaction value corresponding to the target wireless access point accessed this time may be determined according to the voice quality metric value corresponding to each voice call.

In some embodiments, the average value of the voice quality corresponding to the target wireless access point accessed this time may be determined according to the voice quality metric corresponding to each voice call and the number of voice calls performed by the target wireless access point accessed this time. Further, the average voice quality value corresponding to the current access of the target wireless access point may be determined according to the formula (4), or the voice quality metric value corresponding to each voice call performed by the current access of the target wireless access point may be accumulated, and the accumulated result may be divided by the number of voice calls performed by the current access of the target wireless access point to obtain the average voice quality value. If the voice quality average value is larger than or equal to the quality threshold, determining that the user satisfaction value corresponding to the access target wireless access point is a first numerical value; and if the voice quality average value is smaller than the quality threshold, determining that the user satisfaction value corresponding to the current access target wireless access point is a second numerical value.

After determining the user satisfaction value corresponding to the current access of the target wireless access point, the access point score corresponding to the target wireless access point can be updated according to the user satisfaction value, the change score can be determined according to the user satisfaction value and the access point score updated last time by the target wireless access point, and the access point score updated last time and the change score are accumulated to obtain the access point score updated this time by the target wireless access point. Further, the access point score of the target wireless access point updated this time can be calculated according to the above formula (5). When the terminal device searches the target wireless access point again next time, the corresponding selection probability can be calculated according to the latest access point score of the target wireless access point, and the selection strategy of the wireless access point is dynamically adjusted.

It should be noted that, according to the network transmission performance condition of the target wireless access point accessed this time, a specific updating manner for updating the voice quality database may be similar to the calculation manner of the access point score corresponding to the wireless access point in the foregoing embodiment, and reference may be made to the related description in the foregoing embodiment, and details are not repeated here.

Illustratively, fig. 4B is a schematic diagram illustrating an effect of selecting a wireless access point in one embodiment. As shown in fig. 4B, a curve 422 represents the probability that the voice quality metric is greater than the quality threshold when the terminal device accesses the wireless access point AP0 to perform voice call; the curve 424 represents the probability that the voice quality metric is greater than the quality threshold when the terminal device is accessed to the wireless access point AP1 for voice call; a curve 426 represents the probability that the voice quality metric is greater than the quality threshold when the terminal device accesses the wireless access point AP2 to perform a voice call; curve 428 shows the actual probability that the voice quality metric is greater than the quality threshold when the method provided by the embodiment of the present application is used to randomly select a wireless access point to access the Wi-Fi network and perform a voice call when the AP1, the AP2, and the AP3 are simultaneously present. As can be seen from fig. 4B, selecting a wireless access point by using the method provided in the embodiment of the present application can make the probability that the voice quality metric is greater than the quality threshold converge to about 70%, and can ensure that the terminal device is connected to a wireless access point with better and more stable voice quality to perform the VoWiFi service.

In the embodiment of the application, after the terminal equipment accesses the Wi-Fi network through the wireless access point and performs the VoWiFi service each time, the voice quality database can be updated, the access point score corresponding to the accessed wireless access point is dynamically adjusted, the selection strategy of the terminal equipment for each wireless access point is adaptively adjusted based on the reinforcement learning algorithm, the auxiliary terminal equipment can more easily select the wireless access point with better and more stable voice quality to perform the VoWiFi service, the voice service quality of the VoWiFi can be improved, and the voice communication stability is improved.

In some embodiments, the method for selecting a wireless access point may further include: under the condition that the switching condition of switching from the current first network call mode to the VoWiFi mode is met, comparing access point scores corresponding to the first wireless access points with network scores corresponding to the first network to which the first network call mode belongs; and if the access point scores corresponding to the first wireless access points are smaller than the network scores corresponding to the first network, keeping the terminal equipment accessed to the first network.

The access point score corresponding to each first wireless access point is determined according to the voice quality metric value corresponding to each time the terminal device selects the first wireless access point to access the wireless network, and the network score corresponding to the first network is determined according to the voice quality value corresponding to each time the terminal device accesses the first network. The first network may comprise an LTE network and the first network talk mode may comprise a VoLTE mode, or the first network may comprise an NR network and the first network talk mode may comprise a volr mode.

Similar to the calculation of the access point score corresponding to the wireless access point, the network score corresponding to the first network may also be calculated according to the calculation method described in the above embodiment. In the process of accessing the first network by the terminal equipment each time, the voice quality metric value corresponding to each voice call can be determined, and the voice quality average value corresponding to the current access to the first network is determined. Furthermore, the voice quality metric value corresponding to each voice call can be determined according to the above formulas (1) to (3), and the voice quality average value corresponding to the current access to the first network can be determined according to the above formula (4).

When switching from the first network to another type of network, for example, switching from the LTE network to the NR network, or switching from the NR network to the Wi-Fi network, etc., the user satisfaction value corresponding to accessing the first network this time may be determined according to the average voice quality value corresponding to accessing the first network this time, and the network score corresponding to the first network may be updated according to the user satisfaction value. Further, the network score corresponding to the first network may be updated according to the above formula (5).

Under the condition that the switching condition of switching from the current first network call mode to the VoWiFi mode is met, the terminal equipment can compare the access point score corresponding to each first wireless access point with the network score corresponding to the first network to which the first network call mode belongs, if the access point score corresponding to each first wireless access point is smaller than the network score corresponding to the first network, and the voice quality of each first wireless access point searched currently is poor, the terminal equipment can keep accessing the first network, and continue to use the first network call mode to perform voice call service without switching to the VoWiFi mode. If the access point score corresponding to at least one first wireless access point is larger than the network score corresponding to the first network, a target wireless access point can be selected from the first wireless access points with the access point score larger than the network score corresponding to the first network, the Wi-Fi network is accessed through the target wireless access point, VoWiFi IMS registration is initiated, and the current first network call mode is successfully switched to the VoWiFi mode.

Exemplarily, if the current first network call mode is a VoLTE mode, the corresponding first network is an LTE network, the network score corresponding to the LTE network and the access point score corresponding to each first wireless access point can be obtained from the voice quality database, the network score corresponding to the LTE network can be compared with the access point score corresponding to each first wireless access point, if the access point score corresponding to each first wireless access point is smaller than the network score corresponding to the LTE network, it indicates that the voice quality of each first wireless access point searched currently is poor, the terminal device may continue to access the LTE network without switching to the volga mode, and perform a voice call in the VoLTE mode.

The network score corresponding to the LTE network may be dynamically updated and adjusted according to the network transmission performance of the terminal device when the terminal device accesses the LTE network and performs the VoLTE voice service each time, and the manner of dynamically updating and adjusting is similar to the manner of updating the access point score corresponding to the wireless access point described in the above embodiments, and is not repeated here.

In the embodiment of the present application, under the condition that the switching condition for switching from the current first network call mode to the VoWiFi mode is satisfied, if the access point score corresponding to each first wireless access point is smaller than the network score corresponding to the first network, the first network call mode is continuously maintained without switching to the VoWiFi mode, which can avoid the situation that the quality of the voice service is degraded when the terminal device is switched to the VoWiFi mode, and improve the stability of voice communication.
