The technical solution of the present invention will be further described below with reference to FIG. 5.

In this embodiment, mainly for a VoWiFi scenario, the terminal may have multiple eSIMs installed, and one eSIM activates the VoWiFi service, and the terminal detects whether the accessed access point has VoWiFi capability in real time, if the access point has VoWiFi. Capabilities, the terminal will switch to the eSIM with the VoWiFi service enabled.

As shown in FIG. 4, a method for switching an eSIM according to another embodiment of the present invention includes:

Step 402: The terminal detects the VoWiFi capability of the associated access point (target access point) in real time.

Step 404: Determine whether the access point has VoWiFi capability. If yes, go to step 406; otherwise, end.

Step 406: Detecting the VoWiFi-enabled eSIM from the plurality of eSIMs.

In step 408, it is determined whether there is an eSIM with VoWiFi enabled, and if so, step 410 is performed; otherwise, it ends.

Step 410: Switch to the eSIM with VoWiFi enabled.

The detection and determination of the associated access point VoWiFi capability in step 404 is mainly based on determining whether the access point is added to an EPC (Evolved Packet Core) network, such as the terminal discovering the access based on the access point. The ePDG address of the point (specifically, the terminal may trigger the access point to obtain the ePDG address of the access point, or the ePDG address in the identification beacon frame of the access point), and determine whether the access point is connected to the ePDG server based on the ePDG address. If the access point has an ePDG address found and is connected to the ePDG server, the access point is proven to have VoWiFi capability. The terminal automatically switches the eSIM to the VoSIM-enabled eSIM, where the eSIM's VoWiFi capability can be stored in the eSIM.

For a scenario in which the terminal is not associated with the access point, the terminal acquires the access capability capable of detecting the available access point through the WiFi scan, if there is an available VoWiFi access point (ie, the target access point), and the access point terminal has previously Connected or a trusted VoWiFi access point, the terminal can be automatically connected to the VoWiFi-capable access point. For an access point that has VoWiFi capability but the terminal has not been connected before, the terminal can prompt the user to have VoWiFi access nearby. Click to confirm whether to connect, and access the VoWiFi access point according to the access information (such as the access password) input by the user. After the terminal connects to the VoWiFi access point, determine that the access point of the terminal has VoWiFi capability. The method for obtaining an available VoWiFi access point includes: the terminal actively sends a probe response request to the available access point, and the available access point receives the probe response request, and feeds back the probe response frame to the terminal, and the probe response frame is Indicates whether it has VoWiFi capability, indicates that the VoWiFi-capable access point is an available VoWiFi access point in the probe response frame, or can detect that the available access point actively sends a beacon frame to the terminal, and in the beacon frame Indicates whether it has VoWiFi capability, and indicates that the VoWiFi-capable access point is an available VoWiFi access point in the beacon frame.

In the foregoing embodiment, for the VoWiFi scenario, the terminal monitors whether the accessed access point has the VoWiFi capability in real time, and if so, automatically switches to the VoSIM-enabled eSIM, thereby automatically completing the eSIM switchover in the VoWiFi scenario. It is convenient and flexible, and enhances the user experience.

The technical solution of the present invention is described in detail with reference to the accompanying drawings. The technical solution of the present invention proposes a new eSIM switching scheme, which realizes automatic switching of the eSIM, without manual switching by the user, simplifies the entire operation process, and improves the user. The experience of using.

The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes can be made to the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and scope of the present invention are intended to be included within the scope of the present invention.
