Cell Outage Management (COM) is a functionality aiming to automatically detect and mitigate outages that occur in radio networks due to unexpected failures. In this paper, we assume that future Radio Access Networks (RAN) can autonomously detect an outage based on measurements, then we propose a Genetic Algorithm (GA) based mechanism for Cell Outage Compensation (COC). COC is achieved by a GA- based...
The flat architecture becomes the evolution direction of the next generation Mobile Communication Network. It can also lighten the load on the core network effectively. The LIPA (Local IP Access) and SIPTO (Selected IP Traffic Offload) proposed by 3GPP are the typical technologies to implement the flat traffic offload in the user side. Current offload mechanisms for LIPA/SIPTO are either costly for...
Physical Cell Identity (PCI) is cell identifier on the physical layer which can be used to create synchronization signals. There is a mapping between synchronization signals and physical cell identity, and then User Equipment (UE) can search cells through this mapping. Traditionally, PCI was configured during network planning process. While with 3G Long Term Evolution (LTE) has been prevalent in the...
