    A method and apparatus method of filtering packet data for an anonymous user device in a packet data network communication system includes a first step of defining a special context information element containing special context information. 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. A next step includes receiving the activate PDP context request and the special context information element. A next step includes configuring the data packets so that only the special context is allowed. A next step includes assigning an interim identity and interim IP address to the user device. A next step includes mapping the data packets of the configuring step to the interim IP address of the user device. A next step includes defining permissible routing identities per the special context. A next step includes routing the data packets between only those permissible routing identities from the defining step.
