Abstract

A method and apparatus method of filtering packet data for an anonymous user device (12) in a packet data network communication system (11) includes a first step of defining a special context information element containing special context information (60). A next step includes sending the special context information element in an activate packet data protocol (PDP) context request to a network to initiate a call from an anonymous user device (62). A next step includes receiving the activate PDP context request and the special context infromation element (64). A next step includes configuring the data packets so that only the special context is allowed (34). A next step includes assigning an interim IP address to the user device (36). A next step includes defining permissible routing identitites per the special context (40). A next step includes routing the data packets between only those permissible routing identities from the defining steps (42).
