Protocol Stack Adapter for Wireless Network Compression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless network protocols face limitations in data compression, particularly with large protocol payloads, and the Network Transmission Optimization (NTO) technology, designed for standard IP protocols, cannot be directly applied to wireless networks due to structural differences.
Innovation Solution
A protocol stack adaptation method and apparatus that acquires and adapts wireless transmission protocol packets to standard IP data packets for processing by an NTO device, and then re-adapts the processed packets back into wireless transmission protocol packets, enabling the deployment of NTO technology in wireless networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If PDCP layer header compression is used, then protocol header compression is achieved, but compression effect is limited when protocol payload is large
Solution Approach 1:
The patent introduces a protocol adapter as an intermediary component that translates between wireless network protocol packets and standard IP protocol packets. This adapter enables NTO technology to operate in wireless networks by converting the protocol format, thereby resolving the contradiction between achieving compression and adapting to different payload sizes through standard IP processing
2Productivity
If NTO technology is applied to standard IP protocol stack, then network transmission optimization is achieved, but it cannot be directly applied to wireless networks due to protocol stack structure differences
Solution Approach 1:
The protocol adapter serves as a mediator between the wireless network protocol stack and the NTO technology, translating packets from wireless protocol format to standard IP format for NTO processing, and then converting them back. This resolves the incompatibility issue while maintaining optimization benefits
Solution Approach 2:
The patent creates a universal interface through the protocol adapter that allows NTO technology to work with both wireless and standard IP networks. The adapter provides multi-functionality by handling protocol translation in both directions, enabling NTO to be deployed in wireless network environments
3Loss of energy
If existing compression mechanisms are used in wireless networks, then some compression is achieved, but bandwidth occupation cannot be sufficiently reduced
Solution Approach 1:
The patent merges multiple compression mechanisms by combining PDCP layer header compression with application layer compression through the NTO technology. This combined approach processes both headers and payloads, achieving superior compression ratios and reducing bandwidth occupation more effectively than individual mechanisms

AI summary
Disclosed are a protocol stack adaptation method and apparatus, where a network transmission optimization technology can be deployed in a wireless network, thereby optimizing a wireless transmission network. The method includes acquiring a first wireless transmission protocol packet, and detecting, by using a first preset detection rule, whether the first wireless transmission protocol packet carries user data. If the first wireless transmission protocol packet carries user data, the method includes adapting the first wireless transmission protocol packet to a corresponding first standard Internet Protocol (IP) data packet; sending the first standard IP data packet to a network transmission optimization (NTO) device; receiving a second standard IP data packet sent by the NTO device; and, adapting the second standard IP data packet to a corresponding second wireless transmission protocol packet.
