Abstract:
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; using the one or more bearers to create sub-sessions within the mobility session; sending a binding request message from the mobile node to the home agent node, the binding request message comprising one or more downlink key values respectively associated with one or more bearers being requested by the mobile node; receiving a binding acknowledgement message from the home agent node at the mobile node, the binding acknowledgement message comprising one or more uplink key values respectively associated with the one or more bearers; wherein the one or more bearers enable sub-sessions to be created within the mobility session.
