Telematics Box Signaling Method for Network Load Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automotive assistance telematics systems generate significant signaling traffic in communication networks, even when no calls are made, due to continuous registration and location updates, which is inefficient and burdensome for the network, especially considering the low frequency of actual assistance calls.
Innovation Solution
Implement a signaling method where the telematics box listens to the communication network only when necessary, inhibiting registration and location updates unless a call is to be made, thus reducing unnecessary messages and conserving radio resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal continuously performs registration and location updates in the communication network, then the terminal remains reachable and active in the network, but significant signaling traffic is generated which burdens the network
Solution Approach 1:
The terminal performs registration and location updates only periodically or event-driven (when powered on, when making a call, or when moving to a new location area) rather than continuously. This reduces signaling traffic while maintaining network reachability when needed.
Solution Approach 2:
The patent extracts the continuous registration and location update operations from the terminal's active state, separating them from the idle state. The terminal only performs these operations when necessary (power on, call initiation, or location area change) rather than maintaining continuous network presence.
2Measurement precision
If the terminal scans all available carriers and performs registration operations frequently, then the terminal maintains accurate location information and network connectivity, but the signaling traffic increases significantly
Solution Approach 1:
The terminal performs location scanning and registration operations periodically or event-driven (when powered on, when initiating a call, or when moving to a new location area) rather than continuously, reducing signaling traffic while maintaining location accuracy when needed.
Solution Approach 2:
The terminal changes its operational parameters based on state: during idle state it minimizes network operations, while during active state (call in progress) it performs full registration and location update operations to ensure accurate location information.
3Adaptability or versatility
If the terminal remains in standby state and signals movements continuously, then the system can reach the mobile at any time, but the terminal generates significant signaling traffic even without user communications
Solution Approach 1:
The terminal transitions from continuous signaling in standby state to periodic or event-driven signaling. It only performs registration and location updates when powered on, when initiating a call, or when moving to a new location area, reducing network resource consumption while maintaining responsiveness when needed.
Solution Approach 2:
The terminal dynamically changes its signaling behavior based on operational state: in idle state it minimizes network operations, while in active state (call in progress) it performs full registration and location update operations to ensure system responsiveness.
