Conventional time synchronization devices in mobile communication systems lack flexibility and reliability due to independent operation of different time transmission protocols and ports, leading to potential errors and loss of time information when different protocols and ports are used across networks.
Innovation Solution
A method and device that select an optimal time source for each type of time protocol port and a system optimal time source from multiple protocols, prioritizing based on source priority, status, and port priority, with unified mapping and distribution to ensure seamless communication across diverse protocols and ports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple time transmission protocols and ports are independently operated in a conventional time synchronization device, then manual selection is required and preconfigured protocols are used, but flexibility and reliability of the device are decreased
Solution Approach 1:
The patent implements dynamic time source selection where the system automatically switches between different time transmission protocols and ports based on real-time status evaluation. The selection criteria include time source priority, port priority, and time information status, allowing the system to adaptively choose the optimal time source without manual intervention, thereby improving both reliability and ease of operation.
Solution Approach 2:
The system continuously monitors the status of time information from multiple protocols and ports, evaluates their quality based on predefined criteria, and provides feedback to the selection mechanism. This feedback loop enables automatic switching when degradation is detected, ensuring high reliability while eliminating manual selection requirements.
2Reliability
If different types of time transmission protocols and ports are used in different network parts, then cost can be reduced and national security can be guaranteed, but time information status may be lost and errors may happen during selecting time information
Solution Approach 1:
The patent creates a universal time synchronization device capable of handling multiple types of time transmission protocols and ports simultaneously. The device implements a unified selection mechanism that can process different protocol types (such as GPS, PTP, NTP) and port configurations, mapping them to a common evaluation framework. This allows the system to maintain security and cost efficiency by using diverse protocols while preventing information loss through standardized status evaluation and mapping.
Solution Approach 2:
The selection mechanism acts as an intermediary that translates and harmonizes different time transmission protocols and ports into a unified evaluation system. It maps various protocol-specific time information statuses to a common status framework, enabling accurate comparison and selection across different protocol types without losing time information status, thus resolving the contradiction between protocol diversity and information integrity.

AI summary
The present invention discloses a time synchronization method and a time synchronization device for a mobile communication system. When the time status of one type of time protocol is bad, a different type of time protocol having a better status can be automatically selected, thereby the system flexibility and the time information quality and reliability can be effectively enhanced. The time synchronization method for a mobile communication system may comprise: selecting respectively an optimal time source for each type of time protocol port of at least two types of time protocol ports; selecting a system optimal time source from optimal time sources for respective types of time protocol ports.
