Distributed Dynamic Clustering Energy Saving Method in Heterogeneous Networks

Abstract

The invention provides a distributive dynamic clustering energy saving method of heterogeneous network, and aims at solving the problems that the energy saving of most of the existing heterogeneous networks estimate is evaluated and analyzed according to the volume of business of a website, rather than considering the geological positions of the website and business load distribution conditions; some study methods are high in system complexity and are inapplicable to the realistic network. The distributive dynamic clustering energy saving method of the heterogeneous network is characterized in that a low-complexity, high-performance and high-applicability heterogeneous network energy-saving strategy is proposed, and the access attribution judging is performed on the basis of the relay geological position and the business distribution clustering model and according to the energy efficiency priority principle, namely, a searching area is created based on the business volume distributing center of a multi-relay cluster and a macro station, then the relays within the area are closed on the premise that the energy efficiency of the system is raised, and finally the relay sleeping probability costing calculation method. According to the distributive dynamic clustering energy saving method of the heterogeneous network, a relay-closing probability assessment line is obtained according to the multi-relay geological position and the business load distribution, the relay with the minimum sleeping cost is preferably selected to be closed on the premise that the user access is realized and the energy efficiency of the system is raised, and thus the energy saving analysis is done on that basis.

Description

technical field [0001] The invention relates to a distributed dynamic clustering energy-saving method for a heterogeneous network, relates to the energy-saving problem of an LTE (Long Term Evolution) network, and belongs to the technical field of networks in wireless communication networks. Background technique [0002] In LTE communication network, relay technology can achieve higher diversity gain, improve user service quality at cell edge, provide wider signal coverage, and reduce inter-signal interference in the communication environment, which has become a research hotspot in wireless communication in recent years. However, because the single-station coverage capability of the LTE wireless network is weaker than that of 3G (Three generation), the coverage of blind areas and weak areas of outdoor coverage is usually covered by heterogeneous networks. Corresponding to this is the rapid growth of network infrastructure construction and the huge consumption of energy. Toda...

Problems solved by technology

[0005] At present, the energy saving of heterogeneous networks is mostly evaluated and analyzed through the business volume of network sites, without considering the geographical location of the sites and the distribution of business load; some research methods have the problem of high system complexity and cannot be used in real networks.
