Embodiment Construction

[0104]The present invention designs an end-to-end network slicing resource allocation algorithm based on deep reinforcement learning. This method comprehensively considers the access side and the core side, dynamically and reasonably allocates resources, and aims to improve the access rate of the system. In order to obtain the best resource allocation strategy, the factors that affect the access rate in the environment are trained using deep reinforcement learning to obtain a network model. In order to solve the value of the access rate under the determination of wireless resource allocation, an end-to-end resource mapping algorithm is designed for the access side and the core side. With these prerequisites, it is possible to use the trained network to reasonably manage the dynamically changing environment Resource allocation. The specific implementation method is as follows:

[0105] 1. End-to-end model and wireless resource initialization

[0106] A. End-to-end model acces...

Abstract

The invention provides an end-to-end network slice resource allocation algorithm based on deep reinforcement learning (DQN) for the situation that multiple slices of a hybrid service share wireless resources, which algorithm dynamically and reasonably allocates the resources by jointly considering the influence of an access side and a core side from an end-to-end perspective. In order to obtain areasonable DQN network through training, feedback of an environment in the DQN is solved, an end-to-end system access rate optimization problem is decoupled into an access side part and a core side part, and then a dynamic knapsack algorithm and a maximum access link mapping algorithm are designed respectively to obtain maximum end-to-end access. According to the method, resources can be dynamically adjusted by utilizing the trained network no matter in a static environment or a dynamic environment, so that the system access rate is remarkably improved.

Description

technical field [0001] The invention discloses an end-to-end network slicing resource allocation algorithm based on deep reinforcement learning, which can be applied to 5G networks for resource allocation in scenarios containing multiple services. The invention belongs to the technical field of communication network. Background technique [0002] 5G networks will support a large number of diverse business scenarios from vertical industries, such as smart security, high-definition video, smart home, autonomous driving, and augmented reality, etc. These business scenarios usually have different communication requirements. Traditional mobile communication networks are mainly used to serve a single mobile broadband service and cannot adapt to the diversified business scenarios of 5G in the future. If a dedicated physical network is built for each business scenario, it will inevitably lead to problems such as complex network operation and maintenance, high cost, and poor scalabi...
