1. A method for switching access nodes for a terminal capable of implementing a set of applications with at least one remote communicating entity through a packet-switched network, said terminal being associated with a set of first communication contexts, a first communication context comprising a same first transport configuration common to the set of applications and a first application configuration corresponding to a given application, said method comprising iterations of the following steps: receiving by the terminal of an access node switching notification message, said message indicating a second communication context including a second transport configuration, receiving by the terminal of notification message count information, filtering said second transport configuration of said second communication context based on said count information, wherein the filtering step comprises, for a current iteration, the following substeps: deleting said second transport configuration, and updating transport parameters based on said second transport configuration when the count information indicates that the current iteration is the last iteration; and transmitting a filtered notification message to the application corresponding to the current iteration, said steps being reiterated for all the first communication contexts.
