Solution Overview

Problem

Wireless communications systems often fail to provide Ethernet over wireless communications due to a lack of information about the wireless device, hindering the device's ability to obtain desired services.

Innovation Solution

A base station requests capability information from a wireless device for Ethernet type packet data unit sessions, which the device provides, allowing the base station and/or the access and mobility management function to determine and facilitate the instantiation of an Ethernet type packet data unit session, potentially using compressed headers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the wireless communications system does not implement systems for supporting Ethernet techniques, then the system complexity remains low, but the system cannot provide Ethernet over wireless communications service

Engineering Contradiction:
ImproveEthernet over wireless communications capabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The base station requests capability information from the wireless device before establishing Ethernet PDU sessions. This preliminary action ensures the system has necessary device information ready, enabling Ethernet service provisioning without adding complex real-time decision systems.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces an access and mobility management function as an intermediary between the base station and core network. This mediator handles Ethernet session instantiation and capability information management, isolating complexity from both the radio access network and core network.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the base station lacks capability information about the wireless device, then the information processing load is low, but the device cannot obtain desired Ethernet services

Engineering Contradiction:
ImproveEthernet service accessVSAvoidcapability information
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The base station proactively requests capability information from the wireless device during initial connection or before Ethernet service provisioning. This ensures necessary information is available in advance, enabling service establishment without delays or information gaps.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The wireless device provides capability information feedback to the base station, which then forwards relevant information to the access and mobility management function. This feedback mechanism ensures the network has accurate device capability data for Ethernet session management.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If the system does not implement Ethernet PDU session instantiation, then the system complexity remains low, but the wireless device cannot utilize Ethernet over wireless communications

Engineering Contradiction:
ImproveEthernet PDU session capabilityVSAvoidsession management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The access and mobility management function serves as an intermediary that automatically handles Ethernet PDU session instantiation based on capability information. This mediator absorbs the complexity of session management, keeping the base station and core network simple while enabling full Ethernet functionality.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system uses automated decision-making based on pre-collected capability information to instantiate Ethernet sessions without manual intervention. The access and mobility management function autonomously determines session parameters and establishes connections, reducing operational complexity.

Inventive Principle:
Principle #25Self-service
