WLAN-eNB Aggregation for Data Transmission

Solution Overview

Problem

Current mobile communication systems face limitations in transmitting high-capacity data due to frequency resource constraints and the inability to efficiently use non-licensed frequency bands, leading to high costs and data transmission interruptions caused by WLAN access authentication delays and small coverage areas.

Innovation Solution

A method for aggregating WLAN radio resources with eNB carriers, enabling UE and eNB to transmit and receive data through integrated WLAN and eNB carriers, which includes receiving WLAN cell configuration information, performing WLAN association, and setting up IPsec tunnels to overcome authentication delays and coverage issues.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If WLAN radio resource is added to eNB carrier for data transmission, then data processing speed and capacity are enhanced, but authentication delay and coverage limitations occur

Engineering Contradiction:
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent performs WLAN association and IPsec tunnel setup in advance before actual data transmission. The eNB and UE establish the WLAN connection and security tunnels proactively, so that when data needs to be transmitted, the authentication and tunnel configuration are already complete, eliminating delays during actual data transfer.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces an IPsec tunnel as an intermediary layer between the WLAN radio resource and the eNB data transmission. This tunnel encapsulates and protects data packets, enabling seamless integration of WLAN with existing eNB infrastructure while maintaining security and protocol compatibility.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Quantity of substance

If WLAN radio resource is integrated with eNB carrier, then data transmission capacity increases, but coverage area remains limited

Engineering Contradiction:
Core Design Contradiction:
Quantity of substanceVSArea of stationary object

Solution Approach 1:

The patent merges WLAN radio resources with eNB carriers to create a hybrid transmission system. By combining the high-capacity WLAN interface with the established eNB infrastructure, the system achieves both increased data transmission capacity and extended coverage through the eNB's broader network reach.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent adds a new dimension to the communication architecture by integrating WLAN at the radio resource level with eNB carriers. This multi-dimensional approach allows data to be transmitted through multiple paths and interfaces simultaneously, effectively expanding the system's operational capacity beyond the limitations of either technology alone.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Quantity of substance

If multiple frequency resources are used for data transmission, then data capacity increases, but system complexity increases

Engineering Contradiction:
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent creates a universal interface layer that handles multiple frequency resources (WLAN and eNB carriers) through a unified protocol stack. The IPsec tunnel and higher layer signaling provide a common framework that manages different radio interfaces, reducing the complexity that would otherwise arise from handling multiple independent systems.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent dynamically adjusts transmission parameters such as tunnel configuration, bearer setup, and radio resource allocation based on network conditions and data requirements. This parameter-based control allows the system to optimize performance across multiple frequency resources without requiring complex hardware changes for each interface.

Inventive Principle:
Principle #35Parameter changes

AI summary

Provided is a method and apparatus for processing control plane data to enable an evolve Node B (eNB) and a User Equipment (UE) to transmit and/or receive user plane data through a WLAN carrier when the user plane data is transmitted by adding a WLAN radio resource to an E-UTRAN carrier in a radio access network (RAN) level. Particularly, provided is a method for a UE to transmit and receive data, the method including: receiving, from an eNB, wireless local area network (WLAN) cell configuration information which is for transmitting and receiving data using a WLAN radio resource; performing WLAN association based on the WLAN cell configuration information; transmitting a WLAN access confirmation message to the eNB; and receiving, from the eNB through a higher layer signaling, tunnel configuration information which is for the UE to set up a tunnel with the eNB through the WLAN radio resource.
