Abstract: A method for providing a terminal with a service from a service centre, the terminal and the service centre being connected by a communication network, the method comprising: transmitting from the terminal to the service centre a request for the service; adding the terminal to a queue for the service; transmitting to the terminal by a first form of connection one or more indications of the status of the terminal in the queue; determining that the service centre is ready to provide the terminal with the service; establishing a session between the terminal and the service centre using a second form of connection having greater network demands than the first form of connection; and providing the terminal with the service using the session.

Abstract: A method synchronizes signaling messages and multimedia content loading at a callee terminal. A first signaling message transmitted from a caller terminal to initiate a multimedia session establishment is processed to detect, in the first signaling message, information indicating that the multimedia content should be presented in synchronization with a second signaling message necessary to session establishment. The multimedia content is downloaded and presented in accordance with the information indicating that the multimedia content should be presented in synchronization with said second signaling message necessary to session establishment. The second signaling message necessary to session establishment is delayed until after the step of downloading and presenting the multimedia content in accordance with the information indicating that the multimedia content should be presented in synchronization with the second signaling message is completed.
