Abstract: A method of independently managing membership for a group and mobility for members of that group in a communications system includes setting up a group name and a membership for that group including a plurality of names, each of the names indicative of a user within that group; and establishing, separately from the membership, contact information associated with each name. With this method, initiating a session with members of a group includes contacting a first registrar with a request for a session, that registrar including the names indicative of the members of the group and a further registrar associated with each of the names; forwarding the request for a session to the further register that includes contact or end point info for the member; and then forwarding the request to the contact associated with the member.
