Adaptive Random Access Procedure Selection in Wireless Networks

The patent implements dynamic random access procedure selection by enabling the terminal to switch between 4-step and 2-step procedures based on network conditions and user types. The access network device configures different random access procedures and the terminal dynamically selects the appropriate procedure based on received configuration information and current network state, making the system adaptable rather than fixed.

The patent changes the parameters of the random access procedure by introducing configurable elements such as procedure selection indicators, resource allocations, and timing configurations that can be adjusted based on network conditions. The access network device provides configuration parameters that allow the terminal to modify its random access behavior, enabling adaptation to different scenarios without changing the fundamental procedure structure.

The patent implements feedback mechanisms where the access network device monitors the terminal's random access performance and network conditions, then sends response messages that provide guidance on which procedure to use. The terminal receives feedback about parsing results and adjusts its procedure selection accordingly, creating a closed-loop system that optimizes access efficiency while maintaining reliability through informed decision-making.

The patent applies preliminary action by having the access network device pre-configure and indicate the appropriate random access procedure before the terminal initiates access. The network device prepares configuration information and procedure indicators in advance, allowing the terminal to select the optimal procedure (4-step or 2-step) before attempting access, thereby avoiding inefficient procedure selection and improving overall access efficiency.
