Abstract

The present invention relates to a personal user agent acting on behalf of a group of member device agents in a communication network. The personal user agent provides its group of member device agents with a specialized proxy function, while representing the group to the network as a single user agent. To devices on the communication network, the personal user agent behaves and is viewed as a user agent. To the group of member device agents, the personal user agent behaves and is viewed as both a registrar and a proxy server.
