Problems solved by technology

However, this solution still has disadvantages: when the user accesses the trusted network through the proxy server, for example, the user does not sign up for the VoWiFi international roaming service, but accesses the trusted network through the proxy server, the operator cannot identify and restrict the use of the VoWiFi roaming service

Embodiment Construction

[0047] In order to enable those skilled in the art to better understand the technical solution of the present invention, the international roaming restriction method and system provided by the present invention will be described in detail below with reference to the accompanying drawings.

[0048] figure 1 is a schematic structural diagram of a network system in an embodiment of the present invention, such as figure 1 As shown, the network system includes: IMS network and SS7 network. The IMS network includes three parts: an IMS core network (IMS Core), an access network and terminals. The IMS core network is responsible for functions such as service registration, VoWiFi service triggering and prohibition, and message distribution. The Multimedia Telephony Application Server (MMTel AS for short) is the control device for audio and video call services, responsible for call connection and management. The access network Responsible for terminal access control, signaling and med...

Abstract

The invention discloses an international roaming limiting method and system. The method comprises the following steps: sending a registration message to CSCF by a terminal, wherein the registration message comprises a service type and a terminal access state; if the CSCF judges the service type to be VoWiFi, judging whether the terminal access state is a cellular network mode or not; if the CSCF judges the terminal access state to be the cellular network mode, judging whether the terminal is allowed to roam in a roaming place or not according the acquired VLR information, if a fact that the terminal is allowed to roam in the roaming place is judged, allowing a VoWiFi service of the terminal to be registered, and if a fact that the terminal is not allowed to roam in the roaming place is judged, rejecting registration of the VoWiFi service of the terminal; and if the CSCF judges the terminal access state not to be the cellular network mode, judging whether the terminal is allowed to roamin the roaming place according to the acquired position information, if the fact that the terminal is allowed to roam in the roaming place is judged, allowing the VoWiFi service of the terminal to beregistered, and if the fact that the terminal is not allowed to roam in the roaming place is judged, rejecting the registration of the VoWiFi service of the terminal. The method disclosed by the invention realizes limitation of a VoWiFi roaming service.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and system for restricting international roaming. Background technique [0002] Voice over WiFi (also called WiFi calling) means that users use smart terminals with VoWiFi capabilities to make voice and video calls through traditional dial-up methods in a Wi-Fi environment. VoWiFi is a voice service provided by an IP Multimedia Subsystem (IP Multimedia Subsystem, IMS for short) network through Wi-Fi access. [0003] When a user uses the VoWiFi service, the terminal accesses the local IMS network via the Internet through the local WiFi network, so no roaming settlement fee (such as: international roaming scenario) is generated, which reduces the cost of roaming services and facilitates operators to provide cheaper international services. Roaming service. Users can choose whether to sign up for VoWiFi roaming service. When users do not sign up for VoWiFi internati...
