DATA FLOW BETWEEN A COMMUNICATION NODE AND A MOBILE NODE IN A MOBILE NETWORK

摘要

A method of transmitting (2000) a data packet on a communication path from a first communication node to a second communication node in a mobile network. The method includes receiving a route message from the second communication node, wherein the route message includes a list of intermediary addresses between the first communication node and the second communication node. A preferred communication path is generated (3014, 3038) in response to the list of intermediary addresses; and at least one data packet is transmitted (2050) from the first communication node to the second communication node via this preferred communication path. Various communication nodes, a communication system, various communication messages, methods for constructing and sending messages and a method for building an extended binding cache are also described. In this matter, an optimised data path is determined in order to send at least one data packet to an intended receipient, for example in a nested mobile network scenario.
