Abstract (en)
[origin: WO2007141451A2] The invention relates to a method for switching a communication session between first and second terminals (TA, TB) from a first network without an infrastructure (RA) to a second network with an infrastructure (RI) during the degradation of a first transmission channel (CI) between the terminals in the first network. In each terminal, a controller (CQ) detects a degradation of the first channel and stores the last data received from the other terminal. An interface (IC_RA, IC_RI) transmits an invitation message comprising connection parameters relating to a second channel (C2) to the other terminal via one of the networks if the degradation is deemed to be permanent. A unit (EI) establishes the second channel from the other terminal through the second network so that the terminals connect via the second network in order to continue the communication session according to the last stored received data.
