Terminal Buffering Capability Signaling for Tunnel Uplink Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high-speed-railway dedicated networks, not all terminals are capable of buffering data in advance, leading to communication disruptions and resource wastage due to unnecessary uplink resource allocation for terminals incapable of buffering.
Innovation Solution
Terminals and network devices exchange capability information to determine if data buffering is possible, allowing the network to configure uplink resources only for capable terminals, thereby optimizing resource use and preventing disruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If uplink resources are allocated to all terminals for data buffering, then communication service continuity is improved, but network resource waste increases for terminals incapable of buffering
Solution Approach 1:
The patent introduces capability indication parameters to differentiate terminal buffering capabilities. The network device changes resource allocation parameters based on terminal capability reports, allocating uplink resources only to terminals that support buffering, thereby avoiding resource waste while maintaining service continuity for capable terminals.
Solution Approach 2:
The patent applies differentiated resource allocation strategies based on terminal capability. Capable terminals receive uplink resource configurations for data buffering, while incapable terminals receive standard resource allocation. This localized quality approach ensures each terminal receives appropriate resources based on its specific capabilities.
2Measurement precision
If capability reporting mechanism is implemented, then resource allocation accuracy is improved, but signaling overhead increases
Solution Approach 1:
The patent extracts only the essential capability information (buffering capability indication) that the network needs to make resource allocation decisions. By taking out only the necessary capability parameter rather than comprehensive terminal information, the signaling overhead is minimized while still achieving accurate resource allocation based on buffering capability.
3Reliability
If data buffering is enabled for all terminals, then service continuity in low-connectivity regions is improved, but device complexity increases for terminals without buffering capability
Solution Approach 1:
The patent implements dynamic resource allocation where the network adapts its resource configuration based on terminal capability reports. Terminals with buffering capability receive configurations that enable data buffering during low-connectivity periods, while terminals without this capability receive standard configurations. This dynamic approach ensures service continuity for capable terminals without imposing unnecessary complexity on incapable terminals.

AI summary
A method and system for capability reporting and determination, designed to optimize data buffering in communication networks, particularly in environments with potential communication disruptions. A terminal reports its capability to buffer data in advance to a network device. Upon determining that the terminal is capable, the network device configures the terminal to send request information, which may include auxiliary details such as data volume, timing, or duration. Conditions for sending requests are specified, including location, signal strength, and speed thresholds. The system supports high-speed-railway dedicated networks and tunnels as examples of affected regions. Communication apparatuses and non-transitory computer-readable storage media are provided, enabling terminals and network devices to execute the described methods. Configurations may include blocking timers and other conditions for optimizing communication efficiency. This invention enhances data management and communication reliability in constrained network environments.
