Method and Architecture of System for Opening Channels on Establishment of VoIP Communication in p BGAN, SwiftBroadband and FleetBroadband Clear Mode

A system architecture making it possible to dynamically open communication channels of optimized dimension with guaranteed bit rate, the communication protocol used being the RTP protocol, said system architecture being intended to be positioned in an aircraft, a suitcase and/or a ship, and/or a ground station comprising one or more voice-over-IP terminals Ti, said architecture comprising at least the following elements:

• a ground or onboard SIP server (4) comprising at least the following elements:
• a bit rate adapter module situated between at least one transmitting terminal T1 and one receiving terminal T2, said bit rate adapter module being a software function borne by the SIP server which controls, paces, adapts the bit rate of the RTP stream received by a terminal,
• a module for controlling the signaling included in the data streams, said control module comprising a signaling intersection module, a signaling modification module, said signaling interception module receiving the information from a terminal transmitting data and an access control module.
