“…In the cell boundary areas, depending on the overlapping of the cells and the inter-cell handover algorithms, the OSC mode is switched to HR/FR mode. According to [10], the OSC might function in about 10 % smaller coverage area than HR mode in tightly dimensioned environment, which should be taken into account in the interpretation of the presented results.…”

“…As this paper investigates solely the capacity effect of OSC, the radio related functionality of the OSC, HR and FR modes is not presented. The radio performance modeling is presented in [10], which utilizes the results of this paper when estimating the TSL usage as function of the OSC penetration. These two papers thus complete each others as for the final OSC performance model.…”

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.

“…A prediction model for the OSC performance and capacity estimation is presented in [8] and [9] for estimating the OSC gain. The model is based on the analysis of the DHR utilization as a function of a quality category (Q), and is valid for a noise-limited, single cell case in indoors where the user distribution is uniform over the received power levels.…”

The GSM voice capacity can be enhanced by the OSC (Orthogonal Sub Channel) functionality. It allows the sharing of a Half Rate (HR) channel for two separate HR users. OSC makes the pairing of these HR users by dividing the modulation constellation into two separate parts in downlink, and by utilizing the non-correlating training sequences in uplink. OSC thus doubles the offered capacity in those areas where the network conditions allow the pairing. The pairing can be done if the received power level is high enough. In addition, there are quality triggers for the pairing and un-pairing, according to the applied OSC algorithm. This paper investigates the expected OSC gain by taking into account the typical OSC pairing criteria. The effect is analyzed based on the realistic outdoor field measurement data. Furthermore, a model for the OSC performance is developed. This model is utilized as a basis for the simulations that take into account the relevant parameter behavior of the OSC algorithm. The outcome is an estimate of the achievable OSC capacity gain based on the OSC capable handset penetration and network performance statistics, with an indication of optimal OSC parameter values.
