Broadband Cluster Service Access Control for Delay Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In broadband cluster systems, simultaneous requests from multiple cluster terminals for network access can cause network congestion, particularly when high delay requirement services are unable to be processed in a timely manner due to limited broadband resources.
Innovation Solution
A service access control method that determines the service type of a to-be-accessed service, prioritizing services with low delay requirements by controlling their access time to ensure that broadband resources are preferentially allocated to high delay requirement services, thereby avoiding congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a large quantity of cluster terminals simultaneously transmit requests for accessing to the network, then the network access capability is improved, but network congestion occurs and services with high delay requirements cannot be processed in time
Solution Approach 1:
The system performs preliminary classification of services into high delay requirement and low delay requirement categories before access. Terminals with low delay requirement services are instructed to wait for specific sub-frames, while high delay requirement services can access immediately. This preliminary sorting prevents simultaneous access conflicts and ensures timely processing of time-sensitive services.
Solution Approach 2:
The network access process is segmented into different sub-frames based on service type. Low delay requirement services are assigned to specific sub-frames where they can access without causing congestion, while high delay requirement services have dedicated access opportunities. This segmentation separates conflicting access requests in time, resolving the contradiction between access capability and service timeliness.
2Speed
If broadband resources are allocated to services with low delay requirements, then the access speed of these services is improved, but services with high delay requirements cannot be processed in time
Solution Approach 1:
Different quality of service treatment is applied to different service types. Low delay requirement services receive prioritized access in specific sub-frames with guaranteed resources, while high delay requirement services receive standard access treatment. This localized quality differentiation ensures that each service type gets appropriate resource allocation without compromising the other.
Solution Approach 2:
The system implements periodic access opportunities for different service types through structured sub-frame allocation. Low delay services are granted access in specific periodic sub-frames, while high delay services have their own access windows. This periodic structure ensures both service types receive timely access without resource conflicts.

AI summary
A service access control method, a service access control apparatus and a cluster terminal for a broadband cluster system are provided. The method includes: determining a service type of a to-be-accessed service, the service type including a service with a low delay requirement, determining whether a current subframe meets a preset access condition for a service with a low delay requirement when it is determined that the to-be-accessed service is the service with the low delay requirement, and completing access of the to-be-accessed service if the current subframe meets the preset access condition for the service with the low delay requirement.
