DSL Vectoring Joining Process Grouping for Reduced Waiting Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In DSL vectoring systems, subscriber lines often experience long waiting times and inefficient resource utilization due to the low probability of all lines joining simultaneously, leading to prolonged initialization processes and resource wastage.
Innovation Solution
Subscriber lines are grouped into two categories based on their online request times, with the first group starting the joining process and the second group joining when the first group reaches a specific vectoring step, allowing both groups to coexist in different joining processes without requiring the second group to complete the first group's process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all subscriber lines wait for the complete joining process of earlier lines before joining, then the joining process can be completed sequentially and stably, but the waiting time for later lines becomes excessively long and system resources are wasted
Solution Approach 1:
The patent divides subscriber lines into multiple groups based on their online request times. The joining process is segmented into different phases where Group 1 completes initial vectoring steps while Group 2 joins at later vectoring steps. This segmentation allows overlapping joining processes, reducing waiting time while maintaining stability through controlled group management.
Solution Approach 2:
The system performs preliminary grouping of subscriber lines before the joining process starts. By pre-classifying lines into groups based on request times, the system prepares the joining process in advance, enabling later groups to join at appropriate vectoring steps without waiting for complete process termination of earlier groups.
2Device complexity
If all subscriber lines join the DSL vectoring system simultaneously, then the joining process is simple to manage, but the probability of simultaneous joining is low and later lines still need to wait
Solution Approach 1:
The patent introduces dynamic joining mechanisms where different groups of subscriber lines can join at different vectoring steps based on their request times. The system dynamically adjusts the joining timing for each group, allowing Group 2 to join when Group 1 reaches specific vectoring steps, thereby improving efficiency without excessive complexity.
Solution Approach 2:
The joining process continues without interruption by allowing multiple groups to join simultaneously at different vectoring steps. Group 1 and Group 2 can be in different joining phases at the same time, maintaining continuous system progress and resource utilization, thereby improving productivity while keeping management relatively simple.
3Productivity
If the system allows multiple groups of subscriber lines to join simultaneously at different vectoring steps, then the overall joining time is shortened and resources are saved, but the system complexity increases
Solution Approach 1:
The patent segments subscriber lines into distinct groups (Group 1, Group 2, etc.) based on their online request times. Each group is managed separately with specific joining timing, allowing simultaneous joining at different vectoring steps. This segmentation achieves high throughput while keeping group management organized and controllable.
Solution Approach 2:
The system uses feedback mechanisms to track the joining status of different groups and adjust subsequent joining timing accordingly. By monitoring when Group 1 reaches specific vectoring steps, the system automatically triggers Group 2 to join at appropriate times, managing complexity through informed control decisions.

AI summary
The present invention discloses a method and an apparatus for enabling subscriber lines to join a DSL vectoring system the DSL vectoring system and can shorten overall joining time of subscriber lines in a DSL system. The method includes grouping subscriber lines into at least two groups according to time when the subscriber lines request to go online, where the at least two groups of subscriber lines that are obtained after the grouping include a first group of subscriber lines and a second group of subscriber lines; starting a joining process for all the subscriber lines in the first group of subscriber lines; and during the joining process of the first group of subscriber lines, putting all the subscriber lines in the second group of subscriber lines into a joining process.
