Backhaul carrying scheme of TD-LTE microcell base station
Abstract
The deployment scenario,coverage strategy and site assignment of TD-LTE microcell base station(MiBS) are different from macrocell base station(MaBS). Using PTN backhaul network of traditional MaBS to carry TD-LTE MiBS will face three challenges:low network performance,poor security and low intelligence. How to build an efficient,safe and intelligent backhaul network solution for MiBS was investigated. Based on China Mobile’s current network,PON+CMNet,PTN+CMNet,PON+PTN,PTN end-to-end four kinds of small cell backhaul network solutions were proposed and furtherly tested and verified. The result shows that 4 solutions all satisfy the communication business requirements of MiBS. In particular,PON+CMNet solution is better than the others in terms of network security,intelligence and efficiency.
