Abstract

The invention discloses a method for dynamically configuring a computing resource and a data link in a C-RAN network based on an SDN, and relates to the technical field of wireless access networks. The method comprises the following steps: splitting a physical layer and a media access control sub-layer of a virtual base station communication function in a BBU resource pool, respectively realizing on a virtual machine, managing virtual base stations of all data centers by use of a SDN controller, thereby building a virtual cluster between the virtual base stations, and performing data link allocation for the virtual cluster to provide cooperation and communication with higher degree between the base stations, thereby dynamically configuring the computing resource and dynamically adjusting the data link of the virtual cluster. By sufficient use of the virtualization of the computing resource in the C-RAN network based on the SDN, the computing resource is dynamically allocated and the data link is dynamically adjusted, the BBU resource pool utilization rate is improved, the user handover delay is reduced, and better user experience effect is realized.

Description

technical field [0001] The present invention relates to the technical field of wireless access networks, in particular to a method for dynamically configuring computing resources and data links in a SDN (Software Defined Network)-based C-RAN (Clould Radio Access Network) network, for virtual The computing resources are virtualized and clustered, and the SDN controller is used to manage the data links of the virtual clusters to realize the dynamic configuration of the computing resources of the virtual clusters and the dynamic adjustment of the data links. Background technique [0002] Radio Access Network (RAN) is the most important part of cellular wireless network. However, the traditional cellular architecture has many deficiencies, does not meet the needs of today's users and presents a series of shortcomings, mainly in the fact that the current cellular network does not match the rate requirements of today's users, and cannot meet the explosive capacity requirements of ...
