Abstract :
OSC (Orthogonal Sub Channel) is an enhancement for the GSM voice traffic. It provides up to double capacity in the GSM radio interface with the same hardware compared to the previous GSM Half Rate (HR) mode. This paper investigates the effects of the OSC on the capacity utilization compared to the GSM HR as function of the OSC capable handset penetration. The variation of the radio network capacity is studied by taking into account the division of the time slot usage between HR and OSC capable terminals. The results show the achievable capacity gains in terms of reduced time slots and transceiver units with given blocking rate.
