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 initiating a call from an anonymous user device on a home
network. A next step includes assigning an interim identity and interim
IP address to the user device. A next step includes determining a level
of service access of the data packets from the user device. A next step
includes mapping the level of service access of the user device to the IP
address. A next step includes defining permissible routing identities per
the level of service access. A next step includes routing the data
packets of the call along with the associated IP address to only those
location addresses from the defining step.
