Engineering Contradiction Analysis
1Adaptability or versatility
If multiple random access types (legacy and slice-specific) are configured for a terminal device, then the system can support diverse access needs and improve service differentiation, but the terminal device faces complexity in selecting the appropriate random access type
Solution Approach 1:
The patent applies preliminary action by pre-configuring priority relationships between different random access types (legacy random access and slice-specific random access) in the terminal device before the actual random access procedure. The network device configures priority information indicating which random access type should be selected first, so that when multiple types are available, the terminal device automatically follows the pre-established priority without needing to make complex real-time decisions. This resolves the selection complexity while maintaining support for multiple access types.
2Reliability
If slice-specific random access is prioritized, then service differentiation and latency performance improve, but the complexity of determining the priority relationship between access types increases
Solution Approach 1:
The patent applies feedback by having the network device provide priority configuration information to the terminal device based on network conditions and service requirements. The network device determines the priority relationship between legacy random access and slice-specific random access, and feeds this priority information back to the terminal device. This allows the system to adapt to changing network conditions while maintaining manageable complexity, as the network centralizes the decision-making logic and communicates it to the terminal device rather than requiring the terminal to independently determine priorities.
3Ease of operation
If the terminal device autonomously determines random access type priorities, then device complexity is reduced, but the accuracy of random access type selection may deteriorate
Solution Approach 1:
The patent applies the intermediary principle by introducing priority configuration information as a mediator between the network device and the terminal device. Instead of the terminal device autonomously determining priorities (which would be simple but potentially inaccurate) or the network device controlling every detail (which would be complex), the priority configuration information serves as an intermediary that conveys the network's intent to the terminal device in a simplified manner. This mediator enables accurate selection while keeping the terminal device's processing simple, as it just needs to follow the received priority instructions rather than performing complex analysis.

AI summary
The present application relates to the technical field of communications, and discloses a random access type selection method and apparatus, a device, and a storage medium. The method comprises: when a plurality of random access types are configured to a terminal device, the terminal device preferentially selects, from a plurality of random access types, a first random access type to attempt to access, wherein the plurality of random access types comprise conventional random access and slice dedicated random access. The present application provides a random access type selection solution. After the slice dedicated random access type is introduced into a communication system, if a network configures both the conventional random access type and the slice dedicated random access type to the terminal device, the present application provides a random access type selection solution when the terminal device initiates random access, including the preferentially selected random access type, thereby providing guidance for a random access behavior, ensuring the precise implementation of random access, and facilitating the improvement of the success rate of random access.
