Abstract

How to use self-management techniques to reduce the cost of operation and maintenance for LTE Network has become a main challenge for telecommunication operators. In this paper, the allocation method of physical cell identifier (PCI) in LTE Network is analyzed, and an automation PCI allocation system (ACPIAS) framework is proposed. In addition, we propose a policy-based automation PCI allocation method which can modify the policy according to the PCI utilization and the scale of base station. Through this allocation method, the validity of PCI can be guaranteed and the frequency of conflict detection, repair and re-allocation process is reduced. The method can assign PCI not only for eNodeB cells but also for Home eNodeB (HeNB) cells in LTE Network. Finally, a simulation is proposed to validate the correctness of the allocation method.
