Self-Optimisation of Admission Control and Handover Parameters in LTE
In mobile cellular networks the HandOver (HO) algorithm is responsible for determining when calls of users that are moving from one cell to another are handed over from the former to the latter. The Admission Control (AC) algorithm, which is the algorithm that decides whether new (fresh or HO) calls that enter a cell are allowed to the cell or not, often tries to facilitate HO by prioritising HO calls in favour of fresh calls. In this way, a good Quality of Service (QoS) for calls that are already admitted to the network is pursued. In this paper, the effect of self-optimisation of AC parameters on the HO performance in a Long Term Evolution (LTE) network is studied, both with and without the self-optimisation of HO parameters.
