A method and terminal for providing Internet Protocol Television (IPTV) and other communication services to a group of users, such as a family, using an IP Multimedia Subsystem (IMS) network. A group private user identity is associated with a group public user identity and with a plurality of individual public user identities, each of which is associated with a different user in the group. Utilizing the group private User ID and the group public User ID, a browser registers a group subscription with the IMS network. When an individual user enters an identifier such as a PIN, the individual is then registered with the IMS network, while maintaining the group registration with the IMS network and the IPTV network. Individual users can be changed without having to restart the browser.
