Technical Field

Background

In fourth generation mobile communication technology (4G) networks, operators rely on 4G cells throughout the country to provide voice and data services to customers.

There are a large number of 4G cells in the existing network that have low resource allocation but high voice and data traffic. Such cells have a high contribution to the operator's quality of operation and revenue, but their resource usage has approached a limit.
