Solution Overview

Problem

The manual configuration of base stations and gateways in WiMAX networks is time-consuming and does not scale as the network grows, especially when new equipment is added, due to the need to determine which features different vendors' equipment supports for communication.

Innovation Solution

Implementing a capability exchange mechanism where devices in a WiMAX network dynamically configure themselves by negotiating and exchanging capability messages over interfaces like R4, R6, and R8, using a type/length/value message format, to determine and support the necessary features for communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual configuration is used for each base station and gateway, then communication compatibility between different vendors' equipment can be ensured, but the configuration process becomes time-consuming and does not scale as the network grows

Engineering Contradiction:
Improvecommunication compatibilityVSAvoidconfiguration time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent implements automatic capability exchange between base stations and gateways through standardized message protocols. Each device autonomously advertises its supported features and capabilities to neighboring devices, eliminating the need for manual configuration. The capability exchange messages are automatically processed to establish compatible communication parameters, allowing the network to self-configure as devices are added or modified.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent pre-defines standardized capability message formats and feature sets that devices can advertise. By establishing a predetermined framework of supported features and communication protocols before deployment, the system enables automatic compatibility determination without manual intervention during network operation or expansion.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If manual configuration is performed for each device, then precise control over communication features can be achieved, but the process becomes burdensome and difficult to maintain as the network expands

Engineering Contradiction:
Improveconfiguration controlVSAvoidnetwork management complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system enables devices to automatically determine their own configuration parameters by exchanging capability messages with neighboring devices. Each base station and gateway independently identifies its supported features and automatically configures communication parameters based on the capabilities advertised by its partners, eliminating the need for centralized manual management.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent implements dynamic capability advertisement and configuration adjustment. As devices are added, removed, or upgraded in the network, they automatically update their capability messages and re-negotiate communication parameters with neighboring devices, allowing the network configuration to adapt dynamically without manual reconfiguration.

Inventive Principle:
Principle #15Dynamics

3Stability of the object's composition

If static configuration is used when base stations and gateways are set up, then initial communication setup can be completed, but the network cannot adapt when new equipment is added or features need to be updated

Engineering Contradiction:
Improveconfiguration stabilityVSAvoidnetwork adaptability
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent transforms static configuration into a dynamic process through continuous capability exchange. Devices maintain stable baseline configurations but automatically negotiate and update their communication parameters based on current network conditions, added equipment, and feature availability. This allows the network to maintain stability while adapting to changes.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The capability exchange mechanism provides continuous feedback between devices about their supported features and current operational status. This feedback loop enables automatic configuration adjustments when new equipment is added or features are updated, allowing the network to adapt while maintaining overall stability through standardized negotiation protocols.

Inventive Principle:
Principle #23Feedback

AI summary

Techniques for exchanging capabilities in a wireless network are provided. In one embodiment, a first device receives a capability message over a communication link from a second device in a WiMAX network. The communication link may be between any combination of base stations and gateways. For example, the R4, R6, or R8 interface may be used. Other interfaces may also be appreciated in a WiMAX network. The capability message includes one or more capabilities supported by a second device in the WiMAX network. Capabilities to support are then determined based on the one or more capabilities. These capabilities will be supported by the first device for communications with the second device. The first device is then configured to support the determined capabilities. Accordingly, the first device is dynamically configured based on the capability message received.
