Solution Overview
Problem
In wireless communication networks, the introduction of wireless backhaul devices for wireless transmission between wired communication parties leads to IP address consumption and requires modifications in network route configuration, which can be inefficient and resource-intensive.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless backhaul devices are introduced to implement wireless transmission between wired communication parties, then wireless transmission capability is improved, but IP address consumption increases and network route configuration requires modification
Solution Approach 1:
The patent merges the Ethernet frame data transmission function directly into the radio access layer protocol by encapsulating Ethernet frames within the existing protocol structure. This combines the data link layer (Ethernet) and network layer (IP) functions into a unified transmission mechanism, allowing wireless backhaul devices to forward Ethernet frames without requiring separate IP address allocation and route configuration, thereby reducing IP address consumption while maintaining wireless transmission capability.
2Adaptability or versatility
If wireless backhaul devices are introduced to implement wireless transmission between wired communication parties, then wireless transmission capability is improved, but network route configuration complexity increases
Solution Approach 1:
The patent merges the routing function into the Ethernet frame forwarding mechanism by using the radio access layer protocol to directly encapsulate and forward Ethernet frames between wireless backhaul devices. This eliminates the need for separate IP-based route configuration, as the protocol handles frame forwarding based on embedded addressing information within the Ethernet frames themselves, thereby reducing network route configuration complexity while maintaining wireless transmission capability.
3Quantity of substance
If Ethernet frame data is transmitted through radio access layer protocol encapsulation, then IP address consumption is reduced, but protocol processing complexity increases
Solution Approach 1:
The patent makes the radio access layer protocol multi-functional by enabling it to simultaneously perform data encapsulation, addressing, and forwarding functions that were previously handled by separate IP protocol layers. The protocol is designed to handle both control plane and user plane traffic, as well as support multiple Ethernet frame formats and QoS requirements, thereby reducing IP address consumption while managing protocol processing complexity through a unified, versatile protocol structure.
