Network Slice Radio Resource Mapping for Reliable Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Terminal devices face challenges in successfully accessing the correct network slice due to incorrect radio resource selection during initial access or mode transitions, leading to reduced user experience.
Innovation Solution
Provide terminal devices with identification information of a network slice and corresponding radio resources, ensuring the device accesses the correct slice by using the appropriate radio resource based on this information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal device selects radio resources based on priority configuration or sequential scanning, then the selection process is simple, but the terminal device may fail to access the correct network slice
Solution Approach 1:
The network device provides the terminal device with advance information about the correspondence between network slices and radio resources before the terminal needs to access a slice. This preliminary provision of mapping information enables the terminal to directly select the correct radio resource without complex scanning or trial-and-error processes, thereby improving access success rate while avoiding excessive complexity during the actual selection moment
2Loss of time
If the terminal device uses sequential scanning of different radio resources, then the device can explore available resources, but it cannot guarantee accessing the correct network slice in a timely manner
Solution Approach 1:
The network device provides feedback information to the terminal device in the form of mapping relationships between network slices and radio resources. This feedback mechanism enables the terminal to understand which radio resource corresponds to which network slice and make direct selections, eliminating the time-consuming sequential scanning process while guaranteeing correct slice access

AI summary
Embodiments of this application provide a communication method, device, and system. The method includes: A terminal device receives first information from a network device, where the first information includes identification information of a first network slice and information about a first radio resource for accessing the first network slice. The terminal device accesses the first network slice based on the first information by using the first radio resource. According to this method, a success rate of accessing a slice can be improved, so that user experience is improved.
