International Classification:

H04W 4/00

US Classification:

370328

Abstract:

What is disclosed is a communication system and method of operating a communication system, where a wireless access node configured to receive packet communications from wireless devices communicating in sectors over wireless links, and the packet communications indicate an application type. A wireless access node determines wireless device identifiers of the wireless devices and sector identifiers of the sectors and transfers the packet communications, the wireless device identifiers, and the sector identifiers. A packet processing system is configured to receive the packet communications, the wireless device identifiers, and the sector identifiers; determine the application types of the packet communications; determine sector activity profiles by way of the application types, the wireless device identifiers, and the sector identifiers; determine a quality-of-service policies based on the activity profiles; and transfer the quality-of-service policies. The wireless access node is configured to receive the quality-of-service policies and enforce a level of service to the wireless devices over the wireless links based on the quality-of-service policies.

Abstract:

A method and apparatus for processing mobile-IP registration messages. Upon receipt of a mobile-IP registration request (RRQ) message that designates a care-of address matching the mobile-IP home agent's IP address, the RRQ would be dropped. Alternatively, before deciding to drop such an RRQ, the invention may further involve determining whether the home agent is currently functioning as a foreign agent for the requesting mobile node, which would justify the care-of address matching the home agent's IP address. If the home agent is not currently functioning as a foreign agent for the mobile node, then the RRQ would be dropped. On the other hand, if the home agent is currently functioning as a foreign agent for the mobile node, then RRQ processing would proceed as normal.
