A method is described, the method relating to control of a communication between a first device and a second device using a communication protocol including at least a first transaction, and at least one subsequent second transaction. The method can include transmission, by the first device to the second device during the first transaction, of both a maximum acceptable delay between the end of the first transaction and the beginning of the second transaction, as well as an explicit indication of the type of message characterizing the beginning of the second transaction. The second device can then trigger a timer for the delay. The method is applicable to IMS networks.
