Abstract

There are two logical channels in the GSM network namely Traffic Channel (TCH) that carries the actual user traffic and Control / Signalling Channel to control the behavior of the mobile station. SDCCH is one of Control Channel used for call setup process before obtaining the TCH. The traffic increament on a cell causes the unavailability of channels resulting the TCH blocking. High traffic cells need additional channel capacity analysis or optimization process. Optimization process is done before deciding to upgrade the TRX or to construct the new base stations. The first optimization is aimed for changing the SDCCH parameters to TCH if SDCCH Time slots are still available. The second optimization is traffic sharing between GSM 900 to DCS 1800 or otherwise to the same cell. Based on data traffic for four consecutive weeks and the maximum busy hour traffic then adding channel capacity analysis on a cell can be determined. From the results of the audit on the thirteen cells of GSM 900 and DCS 1800 there were 8 cells that can perform the parameter transfer from SDCCH to TCH and 7 cells that can perform traffic sharing on the GSM 900 and DCS 1800 bands.
