Embodiment Construction

[0073] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0074] see figure 1 , figure 1 It is a schematic diagram of a virtualized C-RAN system scenario of the present invention. In the embodiment of the present invention, a downlink transmission scenario of a virtualized C-RAN network is considered. Each base station in the underlying physical network has a certain cache space, and all the cache spaces are centralized to form a virtual network through the "cloud" operation. The cache resource pool (Virtual CacheResource Pool) is deployed together with the virtual baseband processing unit pool (Virtual BBU Pool). The whole network provides S different wireless services for K users in total, let K={1,...,K}, S={1,...,S} denote user set and service set respectively. In the figure, RRH is a remote radio head, CRMS is a centralized resource management system, and Fronthaul and Backhaul represent f...

Abstract

The invention relates to a network slice virtual resource distribution method under a virtualized C-RAN network and belongs to the technical field of communication. Under the premise that average delay constraint of all network slices and network average backhaul link bandwidth consumption constraint are met, the method perform dynamic resource distribution with the maximum average network slice and speed as targets. The distributed resources include spectrum resources (resource blocks) and buffer resources. On each resource schedule time slot, an integrated resource management system can distribute the appropriate amount of resource blocks and buffer materials for each network slice according to a current system state. The virtual resource distribution method disclosed by the invention can improve network slice and speed and simultaneously can ensure service quality of all the slices.

Description

technical field [0001] The invention belongs to the technical field of communications, and relates to a network slice virtual resource allocation method under a virtualized C-RAN network. Background technique [0002] In recent years, mobile data services have experienced substantial growth as the data demands of mobile users have surged. Therefore, operators need scalable solutions that can reduce costs to improve the utilization and coverage of their wireless networks, so as to meet the performance indicators of future 5G networks in terms of capacity, speed and energy efficiency. Among the many promising technologies and network architectures that have been proposed, wireless network virtualization technology and cloud radio access network C-RAN have received extensive attention and research from many scholars and researchers. [0003] Wireless network virtualization is the unified planning and management of the operator's underlying physical network, enabling operators ...
