Dynamic Service Data Splitting for Dual Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In dual connectivity technology, the fixed expected volume of distributed data in service data splitting leads to inefficiencies when the sending rate of the SeNB changes or data transmission delay varies, resulting in accumulated or insufficient data buffering, which decreases the system throughput rate.
Innovation Solution
A method and apparatus that dynamically adjust the expected volume of distributed data based on periodic determination of data volume change status, including buffered-data volume reduced, accumulated, and insufficient states, to adapt to changes in sending rate and data transmission delay, thereby optimizing system throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the expected volume of distributed data is fixed, then the service data splitting process is simple, but data buffering inefficiency occurs when sending rate or transmission delay changes, decreasing system throughput rate
Solution Approach 1:
The patent applies dynamics by transforming the fixed expected volume of distributed data into a dynamic parameter that is periodically adjusted based on actual data volume change status. The SeNB determines whether buffered data volume is increasing or decreasing, and sends adjusted expected volume information to the MeNB, enabling the system to adapt to changing transmission conditions and maintain optimal throughput.
2Stability of the object's composition
If the expected volume of distributed data is fixed, then the data transmission process is stable, but data buffering accumulates or becomes insufficient when sending rate decreases or increases, increasing delay or decreasing throughput rate
Solution Approach 1:
The patent implements feedback by having the SeNB monitor its own data buffering status and send feedback information about data volume change status to the MeNB. This feedback loop enables the MeNB to adjust the distribution of service data accordingly, preventing both data accumulation and insufficiency, thereby maintaining stable transmission without excessive delay.
3Ease of operation
If the expected volume of distributed data is fixed, then the MeNB and SeNB coordination is simple, but data buffering by SeNB becomes inefficient when transmission conditions change, decreasing throughput rate
Solution Approach 1:
The patent applies parameter changes by modifying the expected volume of distributed data parameter based on observed data volume change status. The SeNB monitors whether buffered data volume is increasing or decreasing and adjusts the expected volume parameter accordingly, enabling efficient coordination between MeNB and SeNB while maintaining high throughput rate.
Data Source
AI summary
The application provides a service data splitting method and apparatus. A SeNB receives distributed service data from an MeNB based on a first expected volume of distributed data, and buffers the distributed service data. The SeNB determines a data volume change status of the distributed service data when a preset period expires, where the data volume change status includes a buffered-data volume reduced state, a buffered-data volume accumulated state, and a received-data volume insufficient state. The SeNB adjusts the first expected volume of distributed data based on the data volume change status to obtain a second expected volume of distributed data. and the SeNB sends the second expected volume of distributed data to the MeNB, so that the MeNB performs splitting based on the second expected volume of distributed data.
