Packet filtering for level of service access in a packet data network communication system
First Claim
1. A method of filtering packet data for an anonymous user device in a packet data network communication system, the method comprising the steps of:
- initiating a call from an anonymous user device on a home network;
determining a level of service access of the data packets from the user device;
assigning an interim identity and interim IP address to the user device;
mapping the level of service access of the user device to the IP address;
defining permissible routing identities per the level of service access; and
routing the data packets of the call along with the associated IP address to only those location addresses from the defining step.

Abstract
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.

8. A method of filtering packet data for an anonymous user device in a packet data network communication system, the method comprising the steps of:
-
initiating an emergency call from the user device having a missing identity on a home network;
detecting a missing valid identity of the user device;
assigning an interim identity and interim IP address to the user device;
mapping an emergency service access of the user device to the IP address;
routing the call data packets along with the associated interim IP address to an known IP address of an emergency calling center; and
restricting access to data packets addressed to the assigned interim IP address of the anonymous user device that are not from the known IP address of the emergency calling center. - View Dependent Claims (9, 10, 11, 12)

13. A communication system to filter packet data for an anonymous user device in a packet data network, the communication system comprising:
-
a user device capable of anonymously accessing a home packet data network in the absence of an identity, the user device capable of generating an equipment identity;
a home packet data network operable to provide communications between the anonymous user device with an assigned IP address and an emergency calling center with a known IP address, the packet data network operable to detect a missing identity of the user device;
an emergency packet data network coupled to the home packet data network, wherein upon notification from the packet data network that a user device has no valid identity, the emergency packet data network is operable to assign and map an interim IP address corresponding to the user device and route the call packets with the associated interim IP address to the emergency calling center; and
a packet filter coupled with the packet data network and the emergency packet data network, the packet filter operable to pass only those data packets between the user device and emergency call center that are authorized as emergency communications. - View Dependent Claims (14, 15, 16, 17, 18)
