Structure of a mobile terminal for different communication systems

摘要

A mobile terminal ( 1 ) is to be suitably constructed for different communication systems. The terminal contains in its physical layer exchangeable receive modules ( 3 ) which are coupled with higher layers via a convergence layer ( 4 ). In the higher shifts is arranged a reconfigurable protocol stack ( 9, 10 ) for the different protocols of the communication systems. These protocols are stored in a data base ( 14 ) remote from the terminal ( 1 ) and are loaded in the protocol stack ( 9, 10 ) by means of a standard system ( 11 ).
