摘要： The invention relates to a method and a system for the network-initiated IMS registration of a telecommunication terminal. According to said method, the network transmits a message having specific characteristics to the terminal via an existing communication link, and the terminal recognizes said message as an IMS registration request based on the characteristics of the message and subsequently sends a registration message to the network to register with the IMS.
