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.

QoS signaling for mobile IP

A solution for supporting relocation of an IP session of a mobile node during a network layer handover in a mobile communication system. In the method, from the application context information on the mobile node is detected a first set of capabilities of a network node that that facilitate maintaining the IP session. This first set of capabilities is queried from one or more potential next network node. Applicability of the potential next network node to the relocation of the IP session is determined by the capability information on the first set of capabilities.

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.
