Wireless communication system, cloud virtual base station and resource scheduling method

Abstract

The embodiment of the invention discloses a wireless communication system, a cloud virtual base station and a resource scheduling method. The wireless communication system comprises a cloud virtual base station platform used for virtualizing a base station physical resource of a node on a physical layer into a logic resource on a resource layer and scheduling the logic resource provided by the resource layer to the cloud virtual base station on a resource scheduling layer, wherein the base station physical resource includes a node computing resource and a node network resource, and the cloud virtual base station is a cloud virtual base station with different systems; a cloud virtual base station used for providing a base station service of the preset system based on the logic resource scheduled by the cloud virtual base station platform; and a cloud virtual base station management device used for managing the cloud virtual base station. By adopting the wireless communication system, a multi-system base station can be provided.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a wireless communication system, a cloud virtual base station and a resource scheduling method. Background technique [0002] Multi-mode (or multi-mode) base station (Base Transceiver Station, BTS) is a mainstream direction of base station system development, which can effectively reduce the cost of network construction for operators. space, and can be installed in existing base station equipment rooms, reducing capital investment (Capital Expenditure, CAPEX). In addition, the multi-mode base station shares the transmission equipment and the main equipment, and its energy consumption is also greatly reduced, thus reducing management overhead (Operating Expense, OPEX). [0003] There are mainly two implementation schemes for existing multi-mode base stations: [0004] 1. Taking Universal Mobile Telecommunications System (UMTS) and Long Term Evolution (LTE) as an example, th...

Problems solved by technology

[0005] The main disadvantage of this solution: it is very difficult to support other standards: due to hardware constraints, a new set of hardware is required to support a new standard, and the development cost is high; it is difficult to support more than two standards: three sets of hardware are required for the coexistence of three systems, Due to BTS space constraints, there may not be enough space to accommodate 3 sets of hardware devices, resulting in the inability to support 3-mode

[0007] Compared with Solution 1, this solution has made great progress, but it also has disadvantages: in the scenario where multiple standards are concurrent, services of different standards seize the same set of hardware resources, which may cause damage to the business of a certain standard; BTS hardware failure may cause As a result, services of both formats are damaged and cannot be restored
