Description
Technical Field
The invention relates to a virtual resource management and control system facing a 5G access network, and belongs to the technical field of wireless communication.
Background
In the field of wireless access networks, dedicated hardware and software are often used for processing tasks, and efficient arrangement and resource management of network elements are difficult to realize by applying a resource virtualization technology. The existing wireless access network only performs fixed resource allocation on network elements, the allocation strategy is the highest load according to a base station, and although the resource management mode can meet the network requirements of users, the resource management mode has obvious limitations: firstly, when a user is idle, the base station still occupies physical resources, and the remaining resources cannot be shared with other base stations with high loads, so that hardware waste is caused to a great extent. Secondly, in the process of dynamic change of the task load of the base station, resources cannot be allocated dynamically, so that the resource utilization rate is low, and statistical multiplexing of the resources is difficult to realize.
The reasons for the above are mainly that existing mainstream communication manufacturers often process base station network elements based on dedicated hardware, hardware resources cannot be shared among base stations, coupling of hardware and software is high, and self-adaption to base station load change is difficult.

Currently, for base station virtual resource management, the existing scheme is mainly applied to a 5G core network, and a virtualization technology common in the current IT field, such as a KVM technology and a container technology, is adopted. For a base station task, a Linux kernel is cut on the system level based on CPU kernel scheduling, a special hardware drive is adapted, more kernel-dependent resource management is realized, and the base station resource is not actively subjected to fine management and global scheduling by a protocol high layer, so that the resource utilization rate is low and the management efficiency is low.
