NETWORK-INITIATED IMS REGISTRATION IN A COMMUNICATION SYSTEM
First Claim
1. A method for network-initiated IMS registration of a telecommunication terminal (110) of a user whereby the network (112) transmits a message having specific characteristics to the terminal via an existing communication link, and the terminal recognizes the 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, wherein the network is a packet data oriented network or IP network, characterized in that an IP data packet or a control message (126) is used as the message for initiating the IMS registration.
