Abstract

The Dedicated Control Channel (DCCH) plays an important role in all generations of cellular networks, such as, GSM , HSPA and LTE ; through this logical channel, some information between user equipment and network can be carried. It should be considered that accessing to the DCCH is the entry gate of entrance to the every cellular network; and without a successful DCCH access call-setup process will not be possible. Hence, DCCH channel accessing is one of the most critical issues that RF planner and optimization engineers must consider. More than this, these schemes can contribute to achieve some algorithms in SON for ameliorating the DCCH accessing and serving better services at 4G. In this paper, a real fundamentally established cellular network (GSM) is surveyed and its radio frequency network performance is evaluated and presented on the basis of KPI parameters in general. Furthermore, the DCCH Access Success in particular and different issues, findings, trials and improvements have been summarized. Also, recommendations have been listed to correlate the practical aspects of RF optimization, which affect the improvement of DCCH Access Success rate in cellular networks.
