Abstract

The invention discloses a heterogeneous network resource slicing method with eMBB and URLLC mixed services, belonging to the technical field of mobile communication, comprising the following steps: constructing a heterogeneous fusion composed of base stations and base station users in a 5G heterogeneous fusion network area Network model; establish the maximum utility function based on the heterogeneous fusion network model; use the DQN algorithm to obtain the best resource scheduling and allocation scheme for heterogeneous network resource slices with eMBB and URLLC hybrid services. The invention solves the problem of bandwidth allocation in wireless resources, uses the DQN algorithm in deep reinforcement learning to solve the problem of resource scheduling and allocation between eMBB and URLLC services in a 5G heterogeneous fusion network, and can guarantee eMBB and URLLC services The QoE improves the spectrum efficiency SE and improves the overall utility of the system.

Description

Technical field [0001] The present invention belongs to the field of mobile communication technology, specifically relates to a heterogeneous network resource slicing method having a hybrid service of eMBB and URLLC. Background [0002] With the explosive growth of mobile network data, fifth-generation mobile communication technology has matured to meet a variety of service needs. The most typical types of services in the fifth generation of mobile communication networks are: Enhanced Mobile Broadband (eMBB), Large Scale Machine Type Communication (mMTC), Ultra Reliable and Low Latency Communication (URLLC) services. 5G networks provide resources for the three types of users mentioned above in a sliced manner. When slicing, the base station can adjust the allocation of resources on demand according to the dynamic needs of the user's service type, and can adapt to different network states. Slicing network resources can realize the flexible allocation of 5G network data diversion m...
