Cell-Based Bandwidth Adjustment With Continuous Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bandwidth adjustment methods require suspension of service information transmission, which disrupts the transmission process.
Innovation Solution
A method and terminal that allow for adjusting bandwidth without suspending service information transmission by periodically sending and receiving adjustment information and confirmation information through a control end, using a cell-based system to add or delete cells from the bearer cell group.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If bandwidth adjustment is performed by suspending transmission, then the bandwidth can be adjusted accurately, but the transmission reliability deteriorates due to interruption
Solution Approach 1:
The system performs preliminary actions by sending adjustment information and receiving confirmation information before actually performing the bandwidth adjustment. This allows the receiving end to prepare for the adjustment in advance, ensuring that the transmission can resume smoothly without interruption or data loss, thus maintaining both adjustment accuracy and transmission reliability.
2Adaptability or versatility
If transmission is suspended for bandwidth adjustment, then the bandwidth can be reconfigured, but the productivity decreases due to transmission interruption
Solution Approach 1:
The system maintains continuity of useful action by allowing service information transmission to continue uninterrupted during the bandwidth adjustment process. The adjustment information is exchanged and confirmed while transmission proceeds, ensuring that productivity is maintained while still enabling bandwidth reconfiguration adaptability.
3Extent of automation
If adjustment information is sent through control end, then the adjustment process is managed centrally, but the device complexity increases
Solution Approach 1:
The control end performs multiple functions: it manages bandwidth adjustment by relaying adjustment information between sending and receiving ends, and it can also handle normal service information transmission. This multi-functionality reduces the need for separate dedicated adjustment mechanisms, thereby managing complexity while maintaining centralized automation.

AI summary
Embodiments of the disclosure provide bandwidth adjustment method applicable to sending end, the sending end periodically sends cells to receiving end, and a number of cells sent in each period is n, where n is an integer greater than or equal to 2; in each period, the sending end occupies a cell having a number that is within a bearer cell group of the sending end, the occupied cell is capable of carrying service information, and the method includes: sending adjustment information including adjustment operation to the receiving end, with the adjustment operation being adding a cell number to be adjusted to the bearer cell group of the sending end, or deleting the cell number to be adjusted from the bearer cell group of the sending end; and receiving confirmation information sent by the receiving end, and performing the adjustment operation. Embodiments of the disclosure further provide a terminal.
