IuUP NbUP Procedure Control for Rate Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IuUP/NbUP protocol control methods in 3G mobile communication systems face issues such as asynchronous and monopolized operation of procedure control functions, inability to support origination of UP initialization, time alignment, and rate control, and limited support for multiple UP support modes, leading to dropped requests and inefficient rate control.
Innovation Solution
A method and system that parse received UP frames, generate and buffer control messages, and execute them independently, allowing for simultaneous origination and processing of UP procedure control operations, including rate control, time alignment, and initialization, while supporting multiple UP support modes without significant software modification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If procedure control functions operate in an asynchronous and monopolized manner, then the system can process one control operation at a time, but successive rate control requests are dropped and the system cannot support simultaneous origination and processing operations
Solution Approach 1:
The patent divides the procedure control function into multiple independent procedure control function executing entities. Each entity can independently parse UP frames, generate control messages, and execute control operations simultaneously. This segmentation eliminates the monopolized operation mode and allows parallel processing of multiple control requests, thereby improving both reliability for handling successive requests and productivity for processing throughput.
2Adaptability or versatility
If the system supports only SMpSDU support mode, then the software structure remains simple, but it cannot support multiple UP support modes without significant software modification
Solution Approach 1:
The patent segments the support mode handling by introducing a support mode determining module that identifies the UP support mode in received frames. Based on the determined mode, the system routes frames to appropriate processing modules (SMpSDU processing module or other mode processing modules). This segmentation allows the system to support multiple UP support modes while maintaining a clean software structure without significant modification requirements.
Solution Approach 2:
The support mode determining module acts as an intermediary between the received UP frames and the various processing modules. It determines the support mode and directs frames to the appropriate processing path, enabling the system to adapt to different UP support modes without requiring significant software restructuring.
3Ease of operation
If procedure control modules are independent and cannot restrict each other, then each module can operate autonomously, but the system lacks coordination for simultaneous operations
Solution Approach 1:
The patent creates multiple independent procedure control function executing entities, where each entity is a self-contained unit with its own frame parsing, control message generation, and execution capabilities. These segmented entities operate autonomously without restricting each other, yet the system as a whole achieves reliable coordinated operation through parallel execution of multiple entities processing different control operations simultaneously.

AI summary
The present invention relates to the field of mobile communication, including method, apparatus and system for implementing IuUp/NBUP procedure control. The method includes parsing a received UP frame; generating a control message based on a value obtained from the parsing, and buffering the control message; executing the buffered control message. When multiple time alignment or rate control messages are received, the dropping or suspending of the later received messages due to the execution of a control message may be avoided; by way of setting the state of the message and adding a message identification, the successive rate adjustment procedure may be optimized. The method according to an embodiment of the present invention is capable of originating a rate or time adjustment initiatively. The present invention also discloses an apparatus and system for implementing IuUp/NBUP procedure control, with a good good extensibility, which improves the response efficiency of the system.
