Random Access Resource Selection for Terminal-Initiated Uplink Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current RFID systems primarily support mobile terminated (MT) services and do not facilitate actively triggered access procedures by terminal devices, leading to uplink service processing delays.
Innovation Solution
A method and apparatus that enable terminal devices to receive access resource information from a first device, determine an access resource, and send an access request message on that resource, allowing for terminal-initiated services or signaling, thereby reducing uplink service processing delays through flexible time and frequency domain resource configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If RFID systems only support mobile terminated (MT) services with network-initiated access, then system simplicity is maintained, but uplink service processing delay increases and terminal-initiated services cannot be supported
Solution Approach 1:
The patent inverts the traditional access initiation direction by enabling terminals to actively trigger access procedures through uplink signaling (MSG1) instead of only network-initiated paging. This inversion allows terminal-initiated services while maintaining compatibility with existing network architectures, resolving the contradiction between service responsiveness and system simplicity.
Solution Approach 2:
The patent implements preliminary action by pre-configuring random access resources and parameters in system information before terminals need to initiate access. Terminals can directly use these pre-configured resources to send access requests without waiting for network triggering, thereby reducing uplink service processing delay while keeping the system architecture simple.
2Adaptability or versatility
If random access resources are frequently updated to accommodate dynamic services, then service adaptability improves, but terminal device complexity and processing burden increase
Solution Approach 1:
The patent applies universality by designing a unified random access resource configuration mechanism that serves multiple service types (uplink data, signaling, and future 5G services) through a single set of system information parameters. This multi-functional approach enables the system to adapt to various services without requiring separate configuration mechanisms for each service type, thereby maintaining low terminal complexity while achieving high adaptability.
Data Source
AI summary
This application discloses a random access method and an apparatus. The method includes: A first device sends first information to a terminal device within coverage. When a first service or first signaling initiated by the terminal exists in the terminal device, a first access resource may be selected from an access resource in the first information, and then an access request message is sent to the first device on the first access resource. It may be determined, based on response information of the first device, that the first service or the first signaling can be transmitted to the first device. The terminal device determines a time at which the terminal device needs to perform access, reducing an uplink service processing delay.
