Abstract:
An access network for mobile terminals of the type which comprises: a plurality of radio terminals (BR), a local access network (RLA), a switching circuit (VCX) connected, on the one hand, to at least one other external network and, on the other hand, to said local access network (RLA); said local access network being connected to a number of said radio terminals (BR); each of said terminals (BR) communicating by means of radio resources with mobile terminals (MT); said access network being characterized therein that set-up and release protocols provide for establishing signaling channels and user channels between said switching circuit (VCX) and a mobile terminal (MT) and security protocols (SSCOP) of said channels are implemented, only at the level of said switching circuit (VCX) and said mobile terminals (MT), by exchanging signaling messages between said switching circuit (VCX) and said mobile terminals (MT), and an adaptation server (ARX) which is provided for intercepting, in a transparent manner, the messages sent by said setup and release protocols for implementing, dependent on the contents of said intercepted messages, management protocols of said local access network (RLA) in order to set up and release the signaling channels and the user channels in the said local access network and to reserve corresponding radio resources for said set up and release.
