On the Design of Delay based Admission Control in Hierarchical Networks


Abstract

Today, as the hierarchical cellular system is getting more attention than before, some recent studies introduce delay based admission control (AC) scheme which delays the admission to the macro-embedded small cell for a relatively short time to prevent unnecessary handover caused by the short-term visitors of the small cell area. In such delay based ACs, when we use improper delay parameter, the system frequently makes incorrect handover decisions such as where unnecessary handover is allowed due to too short delaying, or where necessary handover is denied due to too long delaying. In order to avoid these undesirable situations as much as possible, we develop a new delay parameter decision method based on probabilistic cell residence time approximations. By the extensive numerical and analytical evaluations, we derive two useful design insights for determining the proper delay parameter which prevents the incorrect handover decision as much as possible. We expect our delay parameter decision method and design insights can be useful system administration tips in hierarchical cellular system where delay based AC is adopted.
