System and method for resource management in a terminal connected to a communication network

A system for managing a resource in a terminal (10) for an architecture (15, 15′) dedicated to a communications network. The system includes a dedicated architecture resource manager (16, 16′) adapted to process a request for a resource of the dedicated architecture (15, 15′) defined by a process manager (17, 17′) of the dedicated architecture (15, 15′) as a function of an application activated on the terminal (10) and to dialogue with a resource administrator (14) of a dedicated architecture manager (13) to manage a resource of the terminal (10) and to process simultaneously the operation of the dedicated architectures (15, 15′) of the terminal (10) that are connected to a plurality of the communications networks. Application to the management of resources allocated to a communications network from a set of communications networks each offering a set of services via a dedicated architecture (15, 15′) integrated in a terminal (10) connected to a public mobile network to which the user is a subscriber.
