Access network for mobile subscribers

摘要

The mobile unit network access has a switching connection (VCX) to an external network, and to the mobile unit local access (RLA) connected to radio aerial outputs (BR). The protocol establishment and freeing of channels between the switch circuit and mobile unit (MT) are set dependent of the message signals using an adaption server (ARX). The adaption server intercepts transparently following the message intercepted setting the connection and freeing channels as necessary optimising radio resources.
