A method of energy efficiency acquisition for LTE network from the perspective of unit flow energy consumption was provided

which made up for the lack of existing technology can notbe measured under the C-RAN sub-unit sub-unit energy efficiency. The method comprised collecting the traffic list and energy consumption list

according to the default mark and filter rules

real-time traffic and real-time energy consumption of each network subunit in wireless network were collected and reported. Finally

according to the traffic list

energy consumption list and the default time slot

the network sub-unit and/or wireless network energy efficiency was obtained.
