Data Transmission Path Selection for Signaling Load Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data transmission methods in communication networks, such as NB-IOT, face inefficiencies in signaling load and data processing burden due to the need for frequent negotiation of data channels and caching of downlink data packets, which cannot adapt to diverse service scenario requirements.
Innovation Solution
A method that acquires service-related information of User Equipment (UE) to determine the optimal data transmission path, allowing for the selection of either a control plane or user plane scheme based on actual service requirements, thereby improving data transmission efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a data channel is established through SGW, MME and base station negotiation, then downlink data can be transmitted to UE, but signaling load and data processing burden at the network side increases
Solution Approach 1:
The patent extracts the data transmission function from the traditional control plane negotiation path and creates an independent user plane path. The user plane path allows data to be transmitted directly between SGW and base station without requiring MME involvement in each data transmission, thereby reducing signaling load while maintaining transmission reliability
Solution Approach 2:
The patent introduces a user plane gateway as an intermediary element that handles data transmission independently from the control plane. This intermediary allows data packets to flow through a dedicated path (SGW→user plane gateway→base station) without burdening the control plane elements (MME) with data processing tasks
2Reliability
If SGW caches downlink data packets until data channel is established, then data can be transmitted to idle UE, but data processing burden at the network side increases
Solution Approach 1:
The patent extracts the caching function from SGW and relocates it to the user plane gateway. This separation allows SGW to focus on core routing functions while the user plane gateway handles data packet storage and forwarding, reducing the data processing burden on SGW
3Device complexity
If NB-IOT selects a specific transmission scheme for a private network, then implementation is simplified, but it cannot satisfy constantly diversified service scenario requirements
Solution Approach 1:
The patent implements dynamic transmission scheme selection where the network can adaptively choose between control plane and user plane schemes based on real-time service requirements. The system dynamically establishes user plane bearers when needed and falls back to control plane transmission for other scenarios, providing flexibility without increasing implementation complexity
Solution Approach 2:
The patent changes the operational parameters of the transmission system by introducing configurable bearer establishment thresholds and service type classifications. These parameter changes enable the system to adapt to different service scenarios (e.g., frequent small data vs. large data transmissions) while maintaining a unified implementation framework
