Base Station Local Information Forwarding for Intelligent Transport Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In intelligent transport systems, there is a challenge in transmitting real-time information such as braking, acceleration, and accident alerts with minimal delay, as existing communication systems experience long transmission delays due to reliance on core networks, which can lead to safety risks and inefficiencies.
Innovation Solution
The method involves a base station identifying local information within uplink data and directly forwarding it to neighboring base stations without using the core network, thereby reducing transmission delays and improving information propagation by creating a shorter path for critical data like driving status information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If information is transmitted through the core network, then network control and management are improved, but transmission delay increases
Solution Approach 1:
The patent segments information transmission into two paths: local information (e.g., braking, acceleration, accident alerts) is transmitted directly between base stations without routing through the core network, while other information continues to use the core network path. This segmentation resolves the contradiction by eliminating unnecessary core network hops for time-critical information, reducing transmission delay while maintaining core network control for non-urgent traffic.
Solution Approach 2:
The base station acts as an intermediary by directly forwarding local information to neighboring base stations without involving the core network device. This intermediary action creates a shortcut transmission path that bypasses the core network bottleneck, thereby reducing transmission delay for local information while the core network retains overall system control.
2Device complexity
If information is transmitted through the core network, then network management is centralized, but transmission path length increases
Solution Approach 1:
The transmission path is segmented into two types: short direct paths between base stations for local information, and longer paths through the core network for other information. This segmentation allows the system to optimize path length for time-critical information while maintaining centralized management for other traffic types.
Solution Approach 2:
The patent applies local quality by allowing base stations to handle local information transmission autonomously without core network involvement, while other information continues to follow the standard centralized routing. This localized handling reduces transmission path length for local information while preserving overall network management structure.
3Reliability
If all information is processed by the core network, then network control is comprehensive, but transmission speed decreases
Solution Approach 1:
Information is segmented into local information requiring high transmission speed (braking, acceleration, accident alerts) and other information that can tolerate slower transmission. Local information is transmitted directly between base stations at high speed, while other information is processed through the core network, thus resolving the contradiction between comprehensive control and transmission speed.
Solution Approach 2:
Instead of requiring all information to pass through the core network, the patent applies partial action by allowing only local information to bypass the core network and be handled directly between base stations. This partial exemption achieves the necessary transmission speed for critical information while maintaining core network control for the remainder of the traffic.

AI summary
The present invention provides an information transmission method, an apparatus, and a system. A first base station may identify, according to indication information, global information and local information in uplink information sent by user equipment; and if the indication information indicates that the uplink information includes the global information, uploads the global information to a core network device; or if the indication information indicates that the uplink information includes the local information, directly delivers the local information to a neighboring base station, so that the neighboring base station can deliver the local information to user equipment in a cell covered by the neighboring base station, thereby shortening a transmission path of data information, reducing a transmission delay of the data information, and improving a transmission speed of the data information. Because the local information does not need to be forwarded by a core network, a transmission delay of the local information is reduced, and a delay of a communications system is reduced. In addition, load of the core network can also be alleviated when the local information is not processed by using the core network.
