Abstract: To solve high cost, high energy and many other issues in the communication, propose a new network architecture, one of the important applications is to solve the "tidal effect", by BBUs uniform placement to achieve unified deployment of resources to get the purpose of saving computation. But its feasibility has not been verified, this paper will verify its feasibility by data from two aspects of changing the number of base stations and changing the different situations of the base stations. Be measured through simulation and analysis results show that the use of new network architecture can not only save computation, but also enhance the resource utilization and reduce construction, operation and maintenance costs.

Abstract: To meet the requirements of reducing human intervention and operational expenditures (POEX) of LTE SON (Self-organization Networks), a system framework for LTE SON is designed in this paper. In order to match the standard IRP (Integration Reference Point), the framework is divided into six layers, and then functions of some layers are presented.

Abstract: Considering the restriction of physical resource and the environment, we propose a new broadcast path algorithm based on genetic algorithm and ideal point model. The proposed algorithm combines multiple constrains and utilizes the advantages of genetic algorithm in multiple objective programming. Simulation results show that the proposed algorithm reveal better performance on efficiency resource utilization.
