User service request selection method based on end-to-end network slice

Abstract

The invention provides a user service request selection method based on an end-to-end network slice, and belongs to the field of communication technology. A user sends a new service request to a server via a wireless access point; after receiving the request, the server forwards the user service request to an SDN controller, and asks the SDN controller to authenticate and authorize the user; if the user fails to pass authentication and authorization, the server sends a failure response of the new service request to the user; and if the user passes authentication and authorization, the server selects a proper network slice ID for the user and carries out coupling, establishment of a data transmission link among the access network, the SDN controller and an S / P-GW gateway is notified, the server sends a success response of the new service request to the user, and concrete content of the user request is returned. According to the invention, part of network functions is shared between different network slices, and the resource utilization rate is improved.

Description

technical field [0001] The invention belongs to the technical field of communications, and in particular relates to a user service request selection method based on end-to-end network slicing in a novel network architecture. Background technique [0002] The future 5G network will face a variety of application scenarios, of which the three typical application scenarios are enhanced mobile broadband (enhance Mobile Broad Band, eMBB), massive machine type communication (massive Machine Type Communication, mMTC) and ultra-reliable low-latency communication ( ultra-Reliability and Low Latency Communication, uRLLC), different application scenarios have different requirements on mobility, security, delay, reliability and other aspects. It is difficult for existing networks to use one architecture to meet the requirements of all application scenarios. However, it is not realistic to build different physical networks for different application scenarios, because the cost of building ...

AI Technical Summary

Problems solved by technology

There are multiple new service request processes in the user's request for a new service, the process is complicated and cumbersome, and there are too many signaling interactions

At the same time, there is no effective isolation mechanism between different NSs on the RAN side. All NSs share one RAN, and it is prone to the unavailability of a certain network function, resulting in the unavailability of all NSs containing this network function, which will bring inestimable losses.
