A method for processing a request from a first terminal to establish a communication session between the first terminal and a second terminal, the first terminal and the second terminal being operable to communicate via a telecommunication network, the method comprising: receiving at the telecommunication network a request from the first terminal to establish a communication session with the second terminal; determining whether the second terminal is available to support the communication session; and if the second terminal is determined not to be available to support the communication session, transmitting to the first terminal the address of a data set corresponding to the second terminal.

Method and system for establishing a communication system

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.
