[0043] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0044] Wireless-Fidelity (WiFi) networks are increasingly being used as a supplement to cellular data networks. To improve the service delivery of user equipment (UE) in indoor environments, operators offer the Voice over WiFi (VoWiFi) feature. With VoWiFi enabled, UEs can make and receive voice and video calls over the WiFi network. However, currently, UEs lack the ability to flexibly turn VoWiFi on and off. Consequently, UEs often fail to enable VoWiFi multiple times on the same WiFi network, resulting in high UE power consumption.

[0045] In view of this, the present application solves the above problem based on the following ideas: First, determine whether the current location area of ​​the terminal device and the mobile network contract information of the terminal device support the VoWiFi function. If supported, query the VoWiFi function availability information of the target WiFi network to which the terminal device is currently connected in the setting database to determine whether the VoWiFi function is available under the target WiFi network. Secondly, control the use of the VoWiFi function of the terminal device based on the query result. It should be understood that if the terminal device connects to the same WiFi network multiple times, the VoWiFi function availability information of the WiFi network can be queried in the setting database. If it is determined that the VoWiFi function of the WiFi network is unavailable based on the VoWiFi function availability information, then when the VoWiFi function of the WiFi network is found to be unavailable for the first time, the VoWiFi function of the terminal device can be directly turned off. When the terminal device connects to the WiFi network next time, there is no need to try to turn on the VoWiFi function of the terminal device, thereby ensuring the power consumption of the terminal device.

[0046] Figure 1 A flowchart of a VoWiFi control method provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the method includes the following steps:

[0047] 101. Determine the current location area of ​​the terminal device and the mobile network subscription information of the terminal device.

[0048] Among them, the terminal device can be any device with WiFi network function and capable of voice calls, such as a smart phone, tablet computer, smart watch, etc., which are not listed here one by one.

[0049] 102. If the location area and the mobile network contract information both support the VoWiFi function, the VoWiFi function availability information of the target WiFi network to which the terminal device is currently connected is queried in the setting database. The VoWiFi function availability information is used to describe whether the VoWiFi function is available in the target WiFi network.

[0050] The setting database includes a local setting database and / or a cloud setting database.

[0051] When the settings database is a local settings database, it includes at least information about location areas that support the VoWiFi function, the Service Set Identifiers (SSIDs) and BSSIDs of multiple WiFi networks, and information about the availability of the VoWiFi function for each WiFi network. The SSID is a name used to uniquely identify a wireless local area network (WLAN), allowing users to find and connect to the desired network within the WLAN. The BSSID is a unique identifier used to identify each basic service set within the wireless network.

[0052] By querying the local settings database for the VoWiFi function availability information of the target WiFi network currently connected to the terminal device, the user can better control the use of the VoWiFi function of the terminal device, avoid repeated attempts when connecting to the same WiFi network multiple times, and reduce the power consumption of the terminal device of the current user.

[0053] When the setting database is a cloud-based setting database, the cloud-based setting database includes at least location area information supporting the VoWiFi function, SSIDs and BSSIDs of multiple WiFi networks, and VoWiFi function availability information of each WiFi network.

[0054] By querying the cloud settings database for the VoWiFi function availability information of the target WiFi network currently connected to the terminal device, users can achieve data sharing, allowing more users' terminal devices to query the cloud settings database for the VoWiFi function availability information of the WiFi network when connecting to a certain WiFi network, thereby better controlling the use of the VoWiFi function of the terminal device, avoiding the problem of repeated attempts when connecting to the same WiFi network multiple times, and reducing the power consumption of terminal devices of more users.

[0055] When the setting database includes a local setting database and a cloud setting database, in actual application, the VoWiFi function availability information can be queried in the local setting database first. If the VoWiFi function availability information is not found in the local setting database, the VoWiFi function availability information is queried in the cloud setting database.

[0056] Combining the above two situations, by querying the VoWiFi function availability information in the local setting database and the cloud setting database in turn, not only can the power consumption of the terminal device of the current user or more users be reduced, but the probability of querying the VoWiFi function availability information can also be increased, laying the foundation for better control of the use of the VoWiFi function of the terminal device in the future.

[0057] It should be noted that to ensure the accuracy of the VoWiFi function availability information retrieved from the settings database, a lifecycle can be set for the VoWiFi function availability information stored in the settings database. For example, when the VoWiFi function availability information is stored in the settings database for one month, it is considered to be invalid. In this case, when the terminal device queries the settings database for the VoWiFi function availability information, it will indicate that the VoWiFi function availability information does not exist, and the above operation will need to be repeated.

[0058] 103. Based on the query result, control the use of the VoWiFi function of the terminal device.

[0059] In actual applications, a subscriber identity module (SIM) is inserted into the terminal device. The public land mobile network (PLMN) corresponding to the SIM card can be used to determine the mobile network of the terminal device, that is, the operator corresponding to the mobile network of the terminal device, such as China Unicom, China Mobile, China Telecom, etc.

[0060] It should be understood that a PLMN primarily consists of three parts: the country code, the operator code, and the mobile country code. The operator code is a unique identifier for different operators within a specific country or region. For example, China Mobile's operator code is 00, China Unicom's is 01, and China Telecom's is 03. The mobile country code is an identification number that combines the country code and operator code. For example, China Mobile's mobile country code is 46000, China Unicom's is 46001, and China Telecom's is 46003.

[0061] For step 101, the current location area of ​​the terminal device can be determined based on the Global Positioning System (GPS) configured on the terminal device, or the positioning capability of the terminal device's cellular mobile network can be used to determine the current location area of ​​the terminal device, and this is not limited here. The current location area of ​​the terminal device refers to the current location of the terminal device, which can be accurate to the province, city, county, etc., and can be determined based on actual conditions.

[0062] The mobile network contract information of the terminal device may include: the mobile network type of the terminal device, and the contract information under the mobile network type. Among them, the mobile network type of the terminal device includes a mobile network of the mobile type (the corresponding operator is China Mobile), a mobile network of the Unicom type (the corresponding operator is China Unicom), etc. The contract information under the mobile network type can be understood as the mobile network type under the operator. For example, the terminal device has signed a 4G network contract under the mobile network of the mobile type. Simply put, the SIM card inserted by the user in the terminal device is used to handle China Mobile's 4G network service.

[0063] For step 102 and step 103, it should be noted that there are three necessary conditions for the use of the VoWiFi function: 1. The current location area of ​​the terminal device supports the VoWiFi function (for example, the terminal device is currently located in Beijing, and Beijing supports the VoWiFi function); 2. The mobile network contract information of the terminal device supports the VoWiFi function (for example, the SIM card inserted by the terminal device user in the terminal device is for China Telecom's 5G service, and the area where the SIM card is processed is a location area that supports the VoWiFi function, that is, the mobile network contract information supports the VoWiFi function); 3. The target WiFi network currently connected to the terminal device supports the VoWiFi function (for example, the target WiFi network currently connected to the terminal device is a home WiFi network, rather than a WiFi network in an enterprise or other public area, it can be considered that the target WiFi network currently connected to the terminal device supports the VoWiFi function).

[0064] Therefore, after determining the current location area of ​​the terminal device and the mobile network subscription information of the terminal device in step 101, it can be determined whether the current location area of ​​the terminal device and the mobile network subscription information of the terminal device support the VoWiFi function. The specific determination method is as follows:

[0065] When determining whether the current location area of ​​the terminal device supports the VoWiFi function:

[0066] It should be understood that the terminal device stores the location area supporting VoWiFi function when it is shipped. If the location area supporting VoWiFi function is updated subsequently, the server updates the location area supporting VoWiFi function in the preconfigured location area list and interacts with the terminal device to update the location area supporting VoWiFi function to the terminal device. In the specific judgment, it is only necessary to check whether the stored location area supporting VoWiFi function in the terminal device contains the current location area of the terminal device. If it contains, it means that the current location area of the terminal device supports VoWiFi function. If it does not contain, it means that the current location area of the terminal device does not support VoWiFi function.

[0067] In the judgment of whether the mobile network subscription information of the terminal device supports VoWiFi function:

[0068] In actual application, the SIM card of the set operator supporting VoWiFi function can be directly inserted into the terminal device, for example, the SIM card of China Telecom supporting VoWiFi function is directly inserted into the terminal device. At this time, the terminal device can determine whether the SIM card of China Telecom has handled 5G network service by reading the SIM card information. If yes, it is considered that the mobile network subscription information of the terminal device supports VoWiFi function. If no, it is considered that the mobile network subscription information of the terminal device does not support VoWiFi function.

[0069] If it is determined that the current location area of the terminal device and the mobile network subscription information of the terminal device both support VoWiFi function, the VoWiFi function available information of the target WiFi network currently connected by the terminal device can be queried in the set database, and then the VoWiFi function of the terminal device is enabled or closed according to the query result. The specific implementation mode of this step can be referred to in subsequent embodiments, and will not be described in detail here.

[0070] Based on the above, the VoWiFi control method provided in the embodiment of the present application determines the current location area of ​​the terminal device and the mobile network subscription information of the terminal device. If both the location area and the mobile network subscription information support the VoWiFi function, the VoWiFi function availability information of the target WiFi network to which the terminal device is currently connected is queried in the setting database to determine whether the VoWiFi function is available under the target WiFi network. Based on the query result, the use of the VoWiFi function of the terminal device can be controlled. It should be understood that if the terminal device connects to the same WiFi network multiple times, the VoWiFi function availability information of the WiFi network can be queried in the setting database. If it is determined that the VoWiFi function of the WiFi network is unavailable based on the VoWiFi function availability information, the VoWiFi function of the terminal device can be directly turned off when the VoWiFi function of the WiFi network is found to be unavailable for the first time. When the terminal device connects to the WiFi network again next time, there is no need to try to turn on the VoWiFi function of the terminal device, thereby ensuring the power consumption of the terminal device.

[0071] The following describes how to control the use of the VoWiFi function of the terminal device based on the query results:

[0072] As an implementation method: if the VoWiFi function availability information is queried in the setting database, and the VoWiFi function availability information indicates that the VoWiFi function is not available under the target WiFi network, the VoWiFi function of the terminal device is turned off.

[0073] It should be understood that if the VoWiFi function availability information is queried in the setting database, and based on the VoWiFi function availability information, it can be determined that the VoWiFi function is not available under the target WiFi network, it means that the terminal device may have connected to the target WiFi network before, and the target WiFi network cannot support the VoWiFi function. The specific reason may be that the target WiFi network is a public WiFi network and does not meet the requirements for setting up a home WiFi network.

[0074] As another implementation manner: if the VoWiFi function availability information is found in the setting database, and the VoWiFi function availability information indicates that the VoWiFi function is available in the target WiFi network, the VoWiFi function of the terminal device is enabled.

[0075] It should be understood that if the VoWiFi function availability information is queried in the setting database, and based on the VoWiFi function availability information, it can be determined that the VoWiFi function is available under the target WiFi network, then it means that the terminal device may have been connected to the target WiFi network before, and the target WiFi network can support the VoWiFi function. At this time, it is sufficient to enable the VoWiFi function of the terminal device.

[0076] As another implementation method: if the VoWiFi function availability information is not found in the setting database, the VoWiFi function of the target WiFi network is registered; if the registration fails, the VoWiFi function of the terminal device is disabled; if the registration is successful, the VoWiFi function of the terminal device is enabled.

[0077] In actual application, if the VoWiFi function available information is not found in the setting database, it means that the terminal device may not have connected to the target WiFi network before. At this time, the VoWiFi function registration of the target WiFi network can be performed. Figure 2 As shown, the specific steps for registering the VoWiFi function of the target WiFi network include:

[0078] 201. Send a registration request message to a registration server, so that the registration server determines registration response information of the VoWiFi function of the terminal device in the target WiFi network according to the mobile network subscription information of the terminal device and the network bandwidth type of the target WiFi network.

[0079] 202. Receive registration response information sent by the registration server. When the registration fails, the registration response information includes registration failure reason data.

[0080] During specific implementation, the terminal device sends a registration request message to the registration server. The registration request message may carry the mobile network contract information of the terminal device (for example, the operator corresponding to the SIM card in the terminal device is China Telecom, and its network type is 4G network) and the bandwidth type of the target WiFi network (for example, the bandwidth type of the target WiFi network is public network bandwidth).

[0081] After receiving the registration request, the server determines a registration response for the terminal device's VoWiFi function on the target WiFi network based on the information contained in the registration request and sends it to the terminal. If registration is successful, the VoWiFi function is enabled on the terminal device. If registration fails, the VoWiFi function is disabled, and the registration response contains the reason for the registration failure, such as "The target WiFi network does not have a home-type network bandwidth" or "The terminal user is using a 4G network," among other reasons.

[0082] By returning registration failure reason data to the terminal device when registration fails, the user can clearly understand the reason for the registration failure, and then try to re-register after making improvements to the registration failure reason, thereby improving the user experience.

[0083] Furthermore, after the VoWiFi function of the target WiFi network is registered, the VoWiFi function availability information corresponding to the target WiFi network may be generated according to the registration result, so as to be updated into the setting database.

[0084] Specifically, if registration is successful, VoWiFi function availability information is generated, indicating that the VoWiFi function is available on the target WiFi network; or if registration fails, registration failure reason data is obtained, and VoWiFi function availability information is generated, indicating that the VoWiFi function is unavailable on the target WiFi network based on the obtained registration failure reason data. However, regardless of whether registration is successful or failed, the VoWiFi function availability information indicating whether the VoWiFi function is available or unavailable on the target WiFi network needs to be updated to the settings database so that the terminal device can directly query the VoWiFi function availability information in the settings database when it subsequently connects to the target WiFi network. In particular, if the VoWiFi function availability information is found to indicate that the VoWiFi function is unavailable on the WiFi network, the VoWiFi function of the terminal device can be directly turned off without having to try to turn on the VoWiFi function of the terminal device again, thereby reducing the power consumption of the terminal device.

[0085] For ease of understanding, a specific example is provided below to illustrate the solution of this application:

[0086] Assume that the operator of the SIM card inserted in the terminal device is China Telecom, and its mobile network type is 4G network. In actual applications, operators that support the VoWiFi function include China Telecom, and the mobile network type that supports the VoWiFi function is 5G network. Based on this scenario, if Figure 3 As shown, when implementing:

[0087] S1. Determine the current location area of ​​the terminal device and the mobile network subscription information of the terminal device.

[0088] S2. Determine whether the location area and mobile network subscription information support the VoWiFi function. If not, disable the VoWiFi function of the terminal device. If supported, query the setting database for information on the availability of the VoWiFi function of the target WiFi network currently connected to the terminal device.

[0089] S3. If the VoWiFi function availability information is found in the setting database, determine whether the VoWiFi function availability information indicates that the VoWiFi function is available under the target WiFi network. If so, enable the VoWiFi function of the terminal device. If not, disable the VoWiFi function of the terminal device.

[0090] S4. If the VoWiFi function availability information is not found in the setting database, the VoWiFi function of the target WiFi network is registered; if the registration is successful, the VoWiFi function of the terminal device is enabled; if the registration fails, the VoWiFi function of the terminal device is disabled, and the registration failure reason data returned by the server is received, such as "No such name", "NETWORK_FAILRE", "9001USER_UNKOWN", "AUTHENTICATION FAILED", etc.

[0091] To facilitate understanding, the following example illustrates a scenario where registration failure reason data may be returned when enabling the VoWiFi function on a terminal device:

[0092] Scenario 1: A 4G subscriber in a province with VoWiFi has a VoWiFi-enabled device. In this scenario, the device may receive a "9001USER_UNKOWN" error message (because the user is not currently a 5G subscriber). In this case, the user can restart the device, re-insert the SIM card, or re-register at the beginning of each month. Registration failure in this scenario may occur during the authentication phase.

[0093] Scenario 2: A 4G or 5G subscriber in a province with VoWiFi roams to a province where VoWiFi is not supported. In this scenario, the terminal device may receive a "No such name" message (because the terminal device's current location area does not support VoWiFi). In this case, the terminal device will record that the target WiFi network it is currently connected to does not support VoWiFi and upload this VoWiFi availability information to the settings database. Subsequent terminal devices will stop attempting to register for VoWiFi after receiving a "No such name" message. Registration failures in this scenario may occur during the DNS query phase.

[0094] To facilitate understanding of the "authentication phase" and "DNS query phase" in scenarios 1 and 2, let's use an example. The Evolved Packet Data Gateway (EPDG) is a core network element. To enable VoWiFi, a terminal device must first connect to the EPDG and then connect to the core network. For example, if a terminal device connects to a WiFi network and registers for VoWiFi, it first performs a Domain Name System (DNS) query, which essentially queries the EPDG address. If the DNS query successfully finds the EPDG address, VoWiFi registration is successful. If the server returns a failure reason, such as "No such name," during this process, registration failed in the first DNS query phase. If the DNS query successfully finds the EPDG address, the authentication phase begins. If authentication succeeds, the terminal device's user is legitimate, and VoWiFi registration is then performed on the core network.

[0095] Scenario 3: A 5G subscriber (whose terminal device supports the VoWiFi function) in a province where VoWiFi is not deployed roams to a province where the VoWiFi function is supported. In this scenario, the terminal device may receive an "AUTHENTICATION FAILED" message (because the mobile network contract location of the SIM card inserted in the terminal device does not support the VoWiFi function). In this case, the target WiFi network currently connected to the terminal device is recorded as not supporting the VoWiFi function, and the information on the availability of the VoWiFi function is uploaded to the settings database. In this case, you can wait until the list of areas supporting the VoWiFi function is updated, or the user can re-insert the SIM card and try to re-register. The registration failure in this scenario may occur during the authentication stage.

[0096] Scenario 4: A 4G subscriber (terminal device supports VoWiFi function) in a province where VoWiFi is not deployed roams to a province that supports VoWiFi function. In this scenario, the terminal device may receive "AUTHENTICATION FAILED" (because the mobile network contract location of the SIM card inserted in the terminal device does not support the VoWiFi function, and the user has applied for a 4G mobile network, which does not support the VoWiFi function). In this case, it is recorded that the target WiFi network currently connected to the terminal device does not support the VoWiFi function, and the availability information of this VoWiFi function is uploaded to the setting database. In addition, you can wait until the list of areas that support the VoWiFi function is updated, or the user can re-insert the SIM card and try to re-register. The registration failure in this scenario may occur during the authentication stage.

[0097] Scenario 5: China Telecom's 4G or 5G subscribers (terminal devices supporting the VoWiFi function) access China Telecom's WiFi network other than home broadband. In this scenario, the terminal device may receive a "NETWORK FAILRE" message (because the WiFi network the terminal device accesses may be China Telecom's public WiFi network, which does not support the VoWiFi function). In this case, the target WiFi network currently connected to the terminal device is recorded as not supporting the VoWiFi function, and the availability information of this VoWiFi function is uploaded to the settings database. Subsequently, the terminal device will stop attempting to register for the VoWiFi function after receiving "NETWORK_FAILRE". A timer can be set here, and re-registration can be attempted after the time period set by the timer expires. The registration failure in this scenario may occur during the authentication stage.

[0098] Scenario 6: A China Telecom 4G or 5G subscriber (with a VoWiFi-supported device) accesses a Wi-Fi network from a different network. In this scenario, the device may receive a "No such name" message (because the Wi-Fi network the device is connected to could be China Mobile's or China Unicom's, which do not support VoWiFi). In this case, the device will record that the target Wi-Fi network the device is currently connected to does not support VoWiFi, and upload this information to the settings database. Subsequently, the device will stop attempting to register for VoWiFi after receiving a "NETWORK FAILURE" message. Registration failure in this scenario may occur during the DNS query phase.

[0099] In some of the processes described in the above embodiments and the accompanying drawings, multiple operations that appear in a specific order are included, but it should be clearly understood that these operations may not be executed in the order in which they appear in this article or may be executed in parallel.
