Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] A wireless communication resource allocation algorithm based on network slicing of the present invention is based on Lagrangian duality theory and Karush-Kuhn-Tucker (Karush-Kuhn-Tucker, KKT) conditions to combine the rates and delays of different types of users And the differential performance index requirements of reliability and reliability are transformed into the demand for wireless communication resources, and then the wireless communication resources are allocated and managed.

[0031] (1) The principle of the algorithm is analyzed as follows:

[0032] consider as figure 1 In the scenario shown, under the OFDMA system, a base station provides communication services for users belonging to different NSs within its coverage. Let the set of NS be G={1,...,G}, each NS g∈G Corresponds to a business type and its service user set is N ...

Abstract

The invention discloses an algorithm for allocating a wireless communication resource based on network slicing. The algorithm is characterized in that differentiated performance index requirements ofrate, delay and reliability of different types of users are converted into requirements on wireless communication resources based on a Lagrange duality theory and a KKT (Karush-Kuhn-Tucker) condition,on the condition of limited resource total amount and differentiated user requirements of different network slicing services, allocation and management are performed on the wireless communication resources with the purpose of maximizing the total rate of a system. Through adoption of the algorithm of the invention, complexity of a resource allocation optimization algorithm can be reduced, and a system spectrum efficiency can be improved while different user service quality requirements are met.

Description

technical field [0001] The present invention relates to the technical field of communication resource allocation, in particular to a wireless communication resource allocation algorithm based on network slicing. Background technique [0002] Wireless resource management is to use the wireless resource management function of the base station to dynamically manage and optimize resources under the premise of limited resources, so as to improve the system spectrum efficiency and energy efficiency, and ensure the quality of service of users. Therefore, wireless resource management plays an important role in the development of communication technology. has always played an important role in history. In recent years, the wireless resource allocation problem based on OFDMA wireless network has aroused people's widespread attention, and some good research results have been obtained. Existing research can be divided into the following three categories in terms of system speed: resour...
