1Productivity

If heterogeneous LWA networking technology aggregates LTE and WLAN resources, then resource utilization rate is improved, but data transmission performance becomes unsatisfactory or unstable when multiple user equipments simultaneously use LWA technology

Engineering Contradiction:

Improveresource utilization rateVSAvoiddata transmission performance

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent dynamically changes transmission parameters including signal intensity thresholds, data packet assignment ratios, and path selection criteria based on real-time network conditions. The base station adjusts these parameters to optimize both resource utilization and transmission stability for multiple LWA users simultaneously.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The system implements dynamic path selection and data packet assignment that adapts to changing network conditions. The base station continuously monitors signal intensity and transmission status, then dynamically assigns data packets to either WLAN or LTE paths based on current conditions, ensuring stable performance while maintaining high resource utilization.

Inventive Principle:

Principle #15Dynamics

2Reliability

If telecom provider monitors status of both wireless network access point device and base station device, then network status can be maintained, but redundant maintenance and monitoring work causes waste of resources

Engineering Contradiction:

Improvenetwork status monitoringVSAvoidmaintenance and monitoring resources

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent extracts and eliminates redundant monitoring functions by having the base station exclusively monitor and manage LWA data transmission status. The wireless network access point device is removed from the monitoring chain, as it cannot directly monitor LWA transmission status anyway. This reduces maintenance and monitoring resource consumption while maintaining network reliability.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The base station performs multiple functions including LTE data transmission, LWA data transmission management, and monitoring of both LTE and LWA transmission statuses. By consolidating these functions in the base station, the system eliminates the need for separate monitoring mechanisms at the access point, reducing overall resource consumption.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Productivity

If multiple user equipments rush to the same wireless network in LWA technology, then data transmission capacity increases, but system suffers from unsatisfactory or unstable data transmission performance

Engineering Contradiction:

Improvedata transmission capacityVSAvoiddata transmission performance

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent segments LWA data transmission into multiple independent paths: WLAN path and LTE path. The base station divides data packets and assigns them to different paths based on signal intensity and transmission status. This segmentation allows multiple user equipments to simultaneously use LWA technology while maintaining stable performance by distributing traffic across different transmission paths.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The base station acts as an intermediary that manages and coordinates data transmission for multiple LWA user equipments. It monitors signal intensity and transmission status, then intelligently assigns data packets to appropriate paths, preventing direct competition among multiple UEs and ensuring stable performance while maintaining high transmission capacity.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

In a data transmission process of a heterogeneous LWA network, the base station device receives a series of data packets and a signal intensity information. A communication address of each of the series of data packet is directed to a specified user mobile device, and the signal intensity information indicates an intensity of a signal transmitted between the specified user mobile device and a wireless network access point device in communication with the base station device and the specified user mobile device. If the signal intensity information complies with a first specific condition and a status of data transmission associated with the user mobile device complies with a second specific condition, partial data packets are assigned to be transferred to the user mobile device by the wireless network access point device, and partial data packets are assigned to be transferred to the user mobile device by the base station device.
