Telecommunications method, protocol and apparatus for improved quality of service handling

摘要

A telecommunications network adapted to process data packets according to the client mobile internet protocol domain is extended to provide bearer capability, such that sub-sessions can be used to distinguish one portion of traffic from another. A different Quality of Service (QoS) can be assigned to each bearer. The bearers can be setup by a mobile node or a home agent in the telecommunications network.

主权项

1. A method in a host-based mobility managed telecommunications network adapted to process traffic using a mobile internet protocol (MIP) between a home agent node and a mobile node, the method comprising:
providing one or more bearers for transporting data packets within a mobility session between the home agent node and the mobile node; associating a key value with each bearer, wherein the key value represents a quality of service (QoS) descriptor of a data packet being transported by the associated bearer, and the key value is contained in a tunnel header of each data packet based on a tunneling protocol; associating an outer IP header with each bearer, the outer IP header being used to route the associated data packet on a user plane, wherein the outer IP header and the tunnel header are different headers, and wherein the data packets comprise the tunnel header and the outer IP header; using the one or more bearers to create sub-sessions within the mobility session.
