Research On Computing Resource Allocation Algorithms And Implementation Of Resource Management Module Based On Super Base Station

With the rapid development of mobile Internet services,users are increasingly demanding wireless mobile services,which has prompted the mobile communication system access network to evolve from a traditional distributed single base station simple physical overlay deployment mode to a centralized base station pool architecture.The unified scheduling and management features of the architecture improve the utilization of system computing resources and solve the problem of system computing resource waste caused by the imbalance of computing resources such as “tidal effect”.This thesis focuses on the centralized cellular network architecture—the allocation of computing resources for Super Base Station resource pools and the computational resource management module.The main work of the thesis includes:1.The virtual base stations established in the Super Base Station share computing resources,and carry out in-depth analysis and optimization on the computational overhead caused by resource sharing.A load balancing based computing resource allocation algorithm SLB(Service Load Balance,SLB)is proposed.The results show that the algorithm improves the computing resource utilization rate of the Super Base Station resource pool and reduces the number of computing units.On this basis,in order to solve the problem of a large number of virtual base station migration caused by the dynamic change of the virtual base station load,the thesis further proposes a computing resource allocation algorithm RVBSM(Reducing Virtual Base Station Migration,RVBSM)to reduce the virtual base station migration.The characteristics of the virtual base station load moving with time regularly are distributed on a larger time scale.The simulation results show that the algorithm effectively reduces the number of migrations of the virtual base station due to the dynamic change of the load,and reduces the number of migrations.System overhead and network burden.2.This thesis designs and implements the Super Base Station resource pool computing resource management module.According to the characteristics of computing resource monitoring and management in the super base station and the execution requirements of the designed computing resource allocation algorithm,the requirements analysis and the architecture of the resource management module are designed.Through the sub-module such as computing resource monitoring,computing resource allocation,data persistence,and resource mapping maintenance,the unified scheduling and management of the large-scale centralized computing resource pool of the super base station is realized.3.The Super Base Station resource pool computing resource management module and the computing resource allocation algorithm are verified and tested in detail.The methods and strategies of computing resource management for the super base station system designed in this paper are verified.The system verification results show that the Super Base Station resource pool computing resource management module satisfies the dynamic allocation of computing resources,the statistical multiplexing of computing resources,and the scalability of large-scale hardware and software architecture.
