Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and a system for restricting international roaming.
Background
Voice over WiFi (also called WiFi calling) is an intelligent terminal with a VoWiFi capability used by a user, and can perform Voice and video calls in a traditional dialing mode in a Wi-Fi environment. VoWiFi is a voice service provided over an IP Multimedia Subsystem (IMS) network through Wi-Fi access.
When the user uses the VoWiFi service, the terminal accesses the home IMS network through the WiFi network at the location via the Internet, so that roaming settlement fees (such as international roaming scenes) are not generated, the roaming service cost is reduced, and operators can provide cheaper international roaming service conveniently. The user can select whether to sign a VoWiFi roaming service, and when the user does not sign a VoWiFi international roaming service, the operator needs to impose the VoWiFi service roaming limit on the user.
In the prior art, roaming restriction for a user can be realized by distinguishing a trusted WLAN from a non-trusted WLAN: and when the user accesses the non-trusted WLAN, the user is limited to use the VoWiFi. However, this solution has the following drawbacks: when the user accesses the trusted network through the proxy server, for example, the user does not sign the VoWiFi international roaming service, but accesses the trusted network through the proxy server, the operator cannot identify and limit the use of the VoWiFi roaming service.
