Abstract Cellular radio is in use in many European countries mainly to provide pointto- point telephone conversation and - today to a limited degree - data exchange between one mobile and another terminal at (in most cases) fixed location. GSM only offers circuit switched services on the air interface. Future digital mobile radio systems based on TDMA (as in UMTS or TETRA) will use a packet access mechanism, which is known to give a better utilisation of the transmission medium in case of bursty traffic. A packet access mechanism within GSM could provide several new services sucl1 as half duplex voice transmission as in trunked radio systems and medium bitrate data services. Medium variable bitrate data services are required in fields such as rail and road transport informatics. A packet access protocol (CELLPAC V&D) adapted to tt1e GSM TDMA structure is proposed. Simulation results for Packet Voice using voice sources switched by the GSM voice activity detection will be presented considering silence descriptors and handover support (SACCH). Radio wave propagation and the resulting bit errors are taken into account by modelling the channel according to a Rayleigh fading signal.
