Access for mobile terminals network

摘要

An access network for mobile terminals has a switching circuit (VCX) connected to at least one other external network and to a local access network (RLA) which has a number of radio terminals (BR) for providing communication with mobile terminals (MT). Set-up and release protocols provide for signaling channels and user channels between switching circuit (VCX) and a mobile terminal (MT). Security protocol (SSCOP) provides for the channels implemented by exchanging signaling messages at the level of switching circuit (VCX) and mobile terminals (MT). An adaptation server (ARX) intercepts the messages sent by the signaling protocols and implements the intercepted messages. Management protocols of the local access network (RLA) oversee set up and release of the signaling channels and the user channels and reserves corresponding radio resources for the signaling channels.
