Resource allocation method based on energy efficiency in LTE network

Abstract

The invention provides an energy efficiency-based resource allocation method for an LTE (Long Term Evolution) network, which is suitable for the LTE network and solution of a problem that possible uneven distribution of the load in the whole network is led since a user terminal and a corresponding service flow have randomness and time-variance when entering into cells. According to the invention, whether virtual load balancing is executed or not is judged according to a load condition of each cell, thus the whole network is in an equalization state ; and after finishing of the process of the virtual load balancing, bandwidth extension for users in each cell is automatically started, priority of signal channel quality of the users is sequenced from high to low, and a user with higher priority in each round of allocation has a preferential right of being allocated an extra RB (Radio Beacon). According to the energy efficiency-based resource allocation method for the LTE network based on the reasonable and effective utilization of frequency spectrum resource in the whole network, a purpose of reduction of energy consumption of the whole network is eventually achieved, and accordingly, the frequency spectrum utilization ratio of the whole network is greatly improved.

Description

technical field [0001] The present invention relates to an LTE network, in particular to a resource allocation method in the LTE network. Background technique [0002] LTE (Long Term Evolution) is a new technology research and development project launched by 3GPP (the 3rd Generation Partnership Project) in recent years. It mainly uses core technologies such as new architecture, OFDM (Orthogonal Frequency Division Multiplexing), and MIMO (Multiple Input Multiple Output) sign. However, with the rapid development of mobile communication systems and the continuous expansion of network construction scale, the annual power consumption of the entire communication industry has risen sharply, which not only brings a large burden of operating costs to operators, but also brings pollution to the environment . Therefore, realizing green communication and adopting an efficient green wireless network energy-saving algorithm is an indispensable work for the communication industry, especi...

Problems solved by technology

[0007] The problem to be solved by the present invention is: the service flow for the entire network changes dynamically with time, and has great randomness, which causes the load in the entire network to always be in an unbalanced state, so that when the unbalanced low A large number of spectrum resources in the load network are idle and have not been reasonably and effectively utilized
