  • Patent number: 7813343
    Abstract: A quality of service (QoS) signaling packet for arranging QoS connections upon handoff between a mobile node (MN) and a correspondent node (CN) using Internet Protocol (IP), the signaling packet includes one or more QoS flow requirements, one or more classifier parameters, QoS session identification information composed of a previous QoS session ID, a new QoS session ID, and a sequence number. The QoS session IDs are used for establishing a new data path and for added security against spoofing, can be composed of a key-based signature combination of a mobile node's new care of address (CoA) and the sequence number. The packet may also include a previous node address and a cookie, both of which are inserted by a previous node. The previous router address is used for backtracking communications and establishing/updating flow tables while the cookie is used for authentication of node-to-node messages.

  • Patent number: 6564061
    Abstract: A method and apparatus for class based bandwidth scheduling for Quality of Service (QoS) for radio air interfaces. In an embodiment, users of an air interface are assigned to at least one of a plurality of QoS classes. Each class is assigned an elasticity value. When traffic congestion is determined on the air interface during a time frame, the actual rate of data transmission for each user is reduced according to the elasticity of the class to which the user belongs.
