摘要

Process for performing a handoff in QoS oriented between a first and a second path of IP based communication, especially mobile IPv6 Based.Between a mobile node (MN) and a correspondent node (CN).The present invention relates to a process for the realization of a handoff with orientation - QoS between a first and a second path of mobile communication based on IP.Especially mobile IPv6 Based between a mobile node (MN) and a correspondent node (CN).Where the second path of communication belongs to a number of paths of communication with one or more accessible to the mobile node and intermediate bodies where the process presented by the menThe following steps: the selection of a path of communication from the number of paths available to the mobile communication node, and which is designated by the second communication path.B.Generation of information (BU) at the mobile node.Which contains at least one IP address associated with the mobile node through the communication path chosen and the minimum requirements of quality of service (QoS) on the path of communication andScolhida, C. forwarding information along the path of communication between the mobile node and choose the correspondent node, D.To control and, where appropriate, ensure compliance with the minimum requirements of quality of services through the brokers to be covered successively.Where the information of minimum quality requirements of services contains a communication of mobile node and the correspondent node and / or vice versa, and where it is carried out automatically a handoff between PH O and the second path chosen.In the case in which they are met the minimum requirements of quality of services, or the information is blocked and is generated a message in an instance intermediate that is sent to the mobile nodeIn the case that it is not given to comply with the minimum requirements for the quality of services.And then chosen a career choice from the trajectories of communication alternatives available to the mobile node which is chosen as the second path of communication.Being repeated the procedure.
