A method and device for an Internet Protocol Multimedia Subsystem (IMS) terminal to access a network are disclosed. The method includes that: a home location IMS terminal management system of the IMS terminal acquires IMS network access point information of a visit location from a visit location IMS terminal management system of the IMS terminal, wherein the IMS terminal management systems synchronize their respective data via an interface; and the home location IMS terminal management system sends configuration information to the IMS terminal, wherein the configuration information includes the acquired IMS network access point information. In the present invention, the IMS terminal management systems synchronize data via the interface; when the IMS terminal locates in the visit location, the home location IMS terminal management system of the IMS terminal acquires the access point information of the visit location from the visit location IMS terminal management system of the IMS terminal, and sends to the IMS terminal configuration information including the access point information, thus enabling the access point acquired by the IMS terminal to be more accurate, achieving service roaming management, and improving the security of an IMS network. |
