The traffic volume in mobile networks is estimated to grow more than 100 times in the next 10 years. Mobile network operators are expanding their networks to respond to the demand and network vendors constantly improve their processes to address the growth. Long Term Evolution (LTE) technology is the leading technology to build the fourth generation (4G) mobile networks. The LTE base station is referred as evolved NodeB (eNB). The number of eNBs as compared to other network elements is large. The large number of eNBs together with the large number of parameters per eNB increase the requirement for efficient parameter planning process in LTE network roll-out projects. The goal of this study was to improve the eNB transport parameter planning process efficiency by developing a parameter model with defined parameter interrelations.
First the current practises in selected roll-out projects were analysed. The project data were collected applying a questionnaire sent to the network planners. The data were analysed to have an understanding of the current practices.
The study identifies two main parameter areas which benefit most of the parameter model and the defined interrelations. The first area is the eNB capacity related parameters including traffic engineering parameters and the second area is the Internet Protocol (IP) addressing related parameters. This study introduces a set of typical network scenarios and defines the interrelations between the eNB transport parameters in these scenarios.
The developed model and the defined parameter interrelations reduce the number of manual entries in the planning phase. In the introduced scenarios one manual entry defines five to eleven case specific parameters in eNB configuration. This introduces 80% to 90% direct work effort savings and reduces the human errors and thus the non-quality cost as well.
