Dedicated Bearer Configuration for Ultra-Reliable Low-Latency Emergency Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current LTE/LTE-A systems face challenges in providing ultra-reliable and low-latency communication, particularly in meeting the requirements for next-generation mobile communication systems, which include accommodating explosive data traffic, high transmission rates, numerous connected devices, very low end-to-end latency, and high energy efficiency.
Innovation Solution
A method for configuring a separate bearer between a gateway and an eNB to support ultra-reliable and low-latency communication, involving the establishment of dedicated bearers for emergency messages and data transmission, with specific message types and support information transmitted between network nodes to ensure efficient resource allocation and priority scheduling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate dedicated bearer is configured for emergency messages between gateway and eNB, then reliability and latency for emergency communication are improved, but device complexity and network configuration complexity increase
Solution Approach 1:
The patent segments the transmission path for emergency messages by establishing a separate dedicated bearer between the gateway and eNB, distinct from regular data bearers. This segmentation isolates emergency traffic to ensure reliable delivery while maintaining standard bearer configurations for other services, thus improving reliability without unnecessarily complicating the entire network architecture.
Solution Approach 2:
The patent introduces a dedicated bearer as an intermediary transmission path specifically for emergency messages. This intermediary structure acts as a specialized channel that mediates between the gateway and eNB, providing guaranteed delivery for critical messages while leaving the general-purpose bearers unchanged for regular traffic.
2Reliability
If separate bearers are established between multiple network nodes and base station, then service reliability is improved, but network complexity and overhead increase
Solution Approach 1:
The patent applies local quality by configuring dedicated bearers only at specific network locations where emergency message transmission is required (between gateway and eNB), rather than implementing complex bearer structures throughout the entire network. This localized approach ensures high reliability for critical functions while maintaining simple, standard configurations elsewhere in the network.
3Reliability
If dedicated bearers are configured for each eNB between gateway and eNB, then ultra-reliable low-latency communication is achieved, but signaling overhead and resource allocation complexity increase
Solution Approach 1:
The patent segments the bearer configuration by establishing dedicated bearers only for eNBs that require emergency message transmission capabilities, rather than configuring dedicated bearers for all eNBs uniformly. This selective segmentation reduces signaling overhead while ensuring ultra-reliable low-latency communication where specifically needed.
4Reliability
If retransmission mechanisms like H-ARQ are used for unicast data, then data reliability is improved, but latency and complexity for time-critical emergency messages increase
Solution Approach 1:
The patent extracts emergency message transmission from the standard H-ARQ retransmission mechanism by dedicating a separate bearer specifically for emergency traffic. This extraction allows emergency messages to bypass the latency-introducing retransmission protocols used for regular unicast data, achieving both high reliability and low latency simultaneously for time-critical communications.
