Access Node Bandwidth Allocation for Wireless Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication networks face challenges in efficiently managing handovers between different radio access technologies, particularly when the number of wireless devices exceeds a threshold, leading to bandwidth allocation issues and potential degradation of user experience.
Innovation Solution
An access node determines a subscription parameter based on the number of wireless devices and bandwidth allocation, comparing it to a network criteria to decide whether to establish or deny a communication link, ensuring that user experience is not compromised by prioritizing bandwidth allocation and managing handovers between different radio access technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the access node allows wireless devices to establish communication links regardless of network performance, then the ease of operation is improved, but the network performance deteriorates when the number of devices exceeds the threshold
Solution Approach 1:
The access node dynamically changes the parameter of establishing communication links based on the subscription parameter. When the subscription parameter meets the criteria, the access node allows new communication links; when it does not meet the criteria, the access node denies new communication links. This dynamic parameter adjustment resolves the contradiction by adapting network access conditions to current network performance states.
2Productivity
If the access node establishes communication links without checking subscription parameters, then the productivity is improved, but the bandwidth allocation becomes unmanageable
Solution Approach 1:
The access node performs preliminary determination of the subscription parameter before establishing a communication link. By calculating the subscription parameter based on current bandwidth allocation and device count, and comparing it against criteria thresholds, the system proactively manages bandwidth resources before new devices are admitted, preventing bandwidth exhaustion while maintaining efficient onboarding when resources are available.
3Reliability
If the access node monitors and evaluates subscription parameters for each handover request, then the network performance is maintained, but the device complexity increases
Solution Approach 1:
The access node autonomously determines the subscription parameter and makes handover decisions without requiring complex external intervention. The system self-evaluates whether to allow or deny handover requests by comparing the calculated subscription parameter against predefined criteria, enabling automated network performance management while reducing the need for complex external control mechanisms.

AI summary
Systems and methods of providing wireless communication to a wireless device are provided. An access node of a first network associated with a first radio access technology can receive a request to establish a communication link with a first wireless device. The first wireless device can be in further communication with a second network associated with a second radio access technology different from the first radio access technology. The access node can determine that a number of second wireless devices in communication with the access node meets a threshold. When the number of second wireless devices exceeds the threshold, the access node can determine a subscription parameter based on a bandwidth allocation among the number of second wireless devices in communication with the access node. When the subscription parameter meets a criteria, the communication link can be established with the first wireless device.
