Abstract
This paper considers GSM cell system in which pure VAMOS technics is implemented. Traffic properties of the system with VAMOS possibility (probability of unsuccessful pairing of connections in one timeslot and loss probability due to lack of idle channels) are determined. It is found dependence of these properties on the allowable power difference for successful pairing, on offered traffic and on environmental attenuation coefficient. The serving quality of this channel group is compared to an Erlang group with the same parameters. It is proved that probability of bad serving in the group of VAMOS channels is higher than in Erlang group with the same parameters, but not more than two times. The results obtained by calculation are proved comparing them to the results of simulation.
