Embodiment Construction

[0067] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0068] The present invention is a scheme for estimating the utilization rate of BBU resources in the BBU pool, combined with the aggregation and removal algorithm to determine the switching of the BBU state, the state switching of the BBU is dynamically adjusted according to the transmission power utilization rate and the traffic utilization rate, and is summarized for 3 steps:

[0069] First, the transmission power between the RRH and MUE, the rate requirement of each MUE, the number of MUEs, the precoding matrix, the RRH bandwidth, the signal-to-interference-plus-noise ratio and other factors are considered, and the transmission power utilization rate and traffic usage.

[0070] Then, in the BBU pool of the C-RAN, the resource usage rate of each specific BBU is calculated according to the transmission power usage rate and the traffic usage rate. On this b...

Abstract

The invention discloses an energy saving method of a BBU (Base Band Unit) pool under a C-RAN (Cloud Radio Access Network) architecture, and belongs to the field of mobile communication. The energy saving method comprises the particular steps of: firstly, establishing a system model of users, RRHs (Remote Radio Heads) and the BBU pool; acquiring rates of transmitting the RRHs connected with a certain specific BBU to the users and a pre-coding matrix; calculating a transmission power usage rate rho trans and a traffic usage rate rho traff; then calculating a resource usage rate rho BBU of the specific BBU, and setting a kernel variable; pre-defining an upper limit and a lower limit of the resource usage rates of the BBUs, and defining four types of the BBUs; calculating the resource usage rates of all the BBUs in the BBU pool, carrying out partitioning according to four types and carrying out statistics on the numbers of various types; and finally, according to the kernel variables and the type numbers of all the BBUs in the BBU pool, carrying out switching among the BBUs to achieve energy saving. The energy saving method has the advantages that the resource usage rate of the specific BBU can be calculated and states of the BBUs can be dynamically switched; in the case of not influencing QoS of the users, one part of active BBUs in the BBU pool are closed and are enabled to enter a sleep state so as to save energy consumption.

Description

technical field [0001] The invention belongs to the field of mobile communication, and in particular relates to an energy-saving method for a baseband processing pool under a C-RAN (Cloud Radio Access Network) architecture. Background technique [0002] With the proliferation of smartphones and tablets, mobile data traffic is growing rapidly. It is estimated that mobile data traffic will increase 13 times between 2012 and 2017. In order to meet this growing demand, operators need to deploy more equipment, capital expenditures (CAPEX) and operating expenditures (OPEX) increase accordingly, but also lead to more energy consumption. On the other hand, operators are also facing corporate responsibilities for energy conservation and emission reduction. In response to this situation, a wireless access network (Cloud Radio Access Network, C-RAN) came into being. C-RAN is a green wireless access network architecture based on centralized processing, cooperative radio, and real-time...
