Abstract: A service manager intended to be positioned in a telecommunications network implementing a satellite and one or more user networks, the communication protocol relying on the 3G standard or implementing TFT and PDP rules, comprises at least the following modules: a link configuration module which contains one or more static configurations that can be modified by a user, an external-events manager module, a traffic detector module, a configured-TFTs traffic detector plugin, a TFTs management module, a Secondary PDP context management module.

Abstract: A method and a system architecture making it possible to establish in a dynamic manner one or more encrypted tunnels on constrained-band communication networks is provided. It makes it possible in particular to encrypt one or more data streams while guaranteeing the quality of services on the constrained-band systems, in particular for encrypted streams of voice over IP type (Internet protocol) or of data type. These tunnels are thus adapted most suitably to the useful data streams while making it possible to control and assign the necessary values for the quality of service or QoS on these networks.
