Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication networks face inefficiencies in managing client distribution across communication links, leading to congestion, increased collision rates, and reduced throughput.
Innovation Solution
Implementing a balanced admission control algorithm that evaluates and distributes clients across multiple communication links based on idle client quantities and residual link capacity, reserving priority links for service level agreement clients, and dynamically adjusting client assignments to optimize resource usage and reduce congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If clients are distributed across multiple communication links without balanced admission control, then link capacity utilization increases, but collision rates increase and throughput decreases
Solution Approach 1:
The patent dynamically changes the admission threshold parameter based on the number of idle clients and residual link capacity. When idle clients exceed the threshold, new client admission is controlled or blocked, preventing excessive client concentration that causes collisions. This parameter adjustment resolves the contradiction by adapting the system's admission behavior to current link conditions.
Solution Approach 2:
The patent implements feedback mechanisms where the access point continuously monitors idle client quantities and residual link capacity on each communication link. This feedback information is used to dynamically adjust admission thresholds and control client distribution, preventing collision-prone scenarios while maintaining high throughput through informed admission decisions.
2Object-affected harmful factors
If admission control threshold is set low to reduce collisions, then collision rates decrease, but link capacity utilization decreases
Solution Approach 1:
The patent makes the admission threshold dynamic rather than static. The threshold adapts in real-time based on the number of idle clients and residual link capacity measurements. When links have sufficient capacity and few idle clients, the threshold allows higher admission to maximize utilization. When idle clients accumulate or capacity is constrained, the threshold lowers to prevent collisions, thus resolving the contradiction between utilization and collision reduction.
Solution Approach 2:
The system changes the admission threshold parameter based on measured link conditions. By calculating the threshold as a function of idle client count and residual capacity ratios, the system optimizes the balance between admitting enough clients to utilize link capacity and maintaining spacing to reduce collision probability.
3Reliability
If priority links are reserved for service level agreement clients, then service reliability improves, but available capacity for other clients decreases
Solution Approach 1:
The patent applies different quality levels to different communication links by designating priority links for SLA clients and non-priority links for other clients. This local quality differentiation ensures that SLA-critical traffic receives guaranteed capacity and reliable service on dedicated priority links, while non-priority traffic utilizes remaining capacity on non-priority links, thus maintaining both reliability for SLA clients and overall network productivity.
Solution Approach 2:
The patent segments the network capacity into priority and non-priority portions through link designation. By dividing clients into SLA and non-SLA groups and assigning them to different link categories, the system ensures reliable service for priority clients while maintaining efficient utilization of non-priority capacity, resolving the contradiction between reliability and overall productivity.
Data Source
AI summary
This disclosure provides methods, components, devices and systems for link management to improve throughput and operation. Some aspects more specifically relate to techniques for performing admission for clients, such as multi-link operation (MLO) clients, to one or more of a set of communication links of an access point (AP). In some aspects, the AP may initiate an admission control procedure to admit a client to a communication link. The AP may admit the client to a communication link based on a quantity of idle clients on the communication link being less than a threshold quantity of idle clients for the communication link. In some other implementations, the AP may allocate or reserve at least a portion of a link for different types of clients, such as priority clients, so that the AP may maintain high communications quality for an active priority client.
