Network Slice-Aware Random Access for Lower Signaling Delay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, terminal devices do not consider the network slice corresponding to their service requirements during random access, leading to poor support for network slices, resulting in issues like large network delays and high signaling overhead.
Innovation Solution
The terminal device performs random access based on required first network slice information, using appropriate access resources to improve the support effect of the network slice, including determining and selecting cells and access resources that support the necessary network slice.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If terminal device performs random access without considering network slice information, then random access procedure is simple, but network slice support performance is poor
Solution Approach 1:
The terminal device obtains network slice information before performing random access, and selects access resources based on this information in advance. This preliminary consideration of network slice requirements ensures that the terminal connects to the appropriate network slice from the beginning, improving network slice support performance without adding significant complexity to the random access procedure itself.
2Loss of time
If terminal device selects appropriate access resources based on network slice information, then network delay is reduced, but signaling overhead increases
Solution Approach 1:
The patent extracts and utilizes network slice information that is already available in the system (obtained through system information or previous signaling) to guide random access resource selection. By taking out this existing information and applying it to resource selection, the patent reduces network delay without requiring substantial additional signaling, as the network slice information is already present in the communication system.
