Signaling Gateway Small Data Transmission Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing EPS system experiences low data transmission efficiency due to the addition of IP headers when transmitting small data packets, which decreases the payload and efficiency of data transmission.
Innovation Solution
A method is introduced to detect whether data in a GTP-U data packet is of a predetermined type, allowing it to be decapsulated and sent directly to a message gateway without IP encapsulation, thereby avoiding the reduction in payload caused by IP headers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If IP header is added to encapsulate small data packets in EPS system, then data can be transmitted through standard IP protocol, but data transmission efficiency decreases due to reduced payload ratio
Solution Approach 1:
The patent extracts small data packets from the standard IP encapsulation process and routes them through a dedicated signaling path. The signaling gateway identifies small data in GTP-U packets and separates them from regular data flow, sending them directly to the application server without IP header overhead, thus resolving the contradiction between protocol compatibility and transmission efficiency
Solution Approach 2:
The signaling gateway acts as an intermediary between the radio access network and application servers. It receives GTP-U packets, identifies small data through detection mechanisms, and mediates their transmission by routing selected packets through an optimized path that bypasses standard IP encapsulation, thereby improving efficiency while maintaining compatibility for other traffic
2Ease of operation
If GTP-U encapsulation is used for all data transmission, then unified protocol handling is achieved, but signaling overhead increases and transmission efficiency decreases for small data
Solution Approach 1:
The patent segments the data transmission path into two distinct routes: one for regular data using standard GTP-U/IP encapsulation, and another for small data using optimized signaling transmission. The signaling gateway performs segmentation by detecting small data packets and routing them appropriately, eliminating unnecessary encapsulation overhead while maintaining uniform handling for other traffic
Solution Approach 2:
The system dynamically adjusts the transmission path based on data characteristics. The signaling gateway continuously monitors incoming GTP-U packets and dynamically routes small data through the signaling path while maintaining standard routing for other data, creating a flexible system that adapts to different data types and optimizes payload ratio accordingly
