Relay Base Station Decapsulation for Transport Overhead Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, the process of setting up a transport bearer between a self-backhauling base station and a gateway involves two layers of encapsulation, leading to high overhead and reduced transport efficiency.
Innovation Solution
A relay method that decapsulates and re-encapsulates information at a relay base station, ensuring only one layer of encapsulation in the transport procedure, thereby reducing overhead and increasing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two layers of encapsulation are used in the transport procedure, then the relay function is achieved, but the overhead becomes high
Solution Approach 1:
The patent extracts and removes one layer of encapsulation from the transport procedure. Instead of having two layers of encapsulation (one from the self-backhauling base station and another from the relay base station), the invention eliminates the redundant encapsulation layer, allowing the relay base station to forward packets directly without double encapsulation, thus reducing overhead while maintaining relay functionality
Solution Approach 2:
The relay base station is designed to perform multiple functions: it acts as both a relay node for backhaul communication and a gateway for accessing the self-backhauling base station. This multi-functionality allows the system to avoid separate encapsulation layers by integrating the relay and gateway functions, reducing the overall encapsulation overhead
2Reliability
If two layers of encapsulation are used in the transport procedure, then the relay function is achieved, but the transport efficiency is reduced
Solution Approach 1:
The patent removes the redundant encapsulation layer that was causing transport efficiency degradation. By eliminating one layer of encapsulation and decapsulation, the processing time and overhead at relay nodes are reduced, directly improving transport efficiency while preserving the relay function
Solution Approach 2:
The invention allows packets to skip through the relay base station with minimal processing. Instead of performing full encapsulation and decapsulation operations, the relay base station can forward packets directly using the existing single layer of encapsulation, reducing processing time and improving transport efficiency

AI summary
Embodiments of the present invention disclose a relay method of a transport bearer, an apparatus and a communication system. According to the technical solutions in the present invention, when receiving information encapsulated by a source device and sent by the source device, a relay base station first decapsulates the information, encapsulates the information again, and then sends the encapsulated information to a host device, thus ensuring that the information has only a layer of encapsulation in the transport procedure, so as to avoid a case that a high overhead caused by two layers of encapsulation occurs in the transport procedure. Compared with the prior art, the overhead in the transport procedure may be reduced, and the transport efficiency may be increased.
