Terminal Random Access Data Buffering Across Retry Attempts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In scenarios with low random access success rates, existing technologies do not effectively manage data processing between consecutive two-step random access procedure attempts, leading to potential data loss and reduced reliability.
Innovation Solution
A method and terminal implementation that buffers and regenerates data content during failed two-step random access procedures, allowing for efficient data transmission by reusing or regenerating data based on transmission resource size changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a terminal continuously initiates random access procedure attempts in scenarios with low random access success rate, then the probability of eventual access success increases, but data loss increases due to lack of data processing management between attempts
Solution Approach 1:
The terminal performs preliminary actions by buffering data content before random access attempts and regenerating data content between attempts. This ensures data is preserved and ready for transmission whenever access succeeds, preventing data loss during continuous retry scenarios.
Solution Approach 2:
A data processing management mechanism acts as an intermediary between consecutive random access attempts. This intermediary buffers and manages data content, ensuring data persists across attempts and is properly handled during the random access procedure, thus preventing data loss.
2Reliability
If data content is buffered and regenerated between consecutive random access attempts, then data transmission reliability improves, but processing complexity increases
Solution Approach 1:
The terminal performs self-service by autonomously buffering and regenerating its own data content between random access attempts without requiring external network assistance. This self-managed data processing simplifies the overall system architecture while maintaining high data transmission reliability.

AI summary
This disclosure provides a random access method and a terminal. The method includes: sending first data in first data content in an ith random access procedure, where the first data content is data content buffered in an (i−1)th random access procedure, at least one of the ith random access procedure and the (i−1)th random access procedure is a two-step random access procedure, and i is an integer greater than 1.
