Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a communication device maintains time synchronization packets for multiple clock sources to meet different service requirements, then time synchronization precision is improved, but power consumption increases and device performance deteriorates
Solution Approach 1:
The patent applies dynamics by making the time synchronization packet processing state changeable between activated and deactivated based on service requirements. The terminal device dynamically adjusts its processing state according to whether time synchronization is needed for a particular clock source, transforming a static always-active system into a dynamic conditionally-active one, thereby reducing power consumption while maintaining precision when required
Solution Approach 2:
The patent changes the operational parameter of time synchronization processing from a fixed state to a variable state. By introducing an activated/deactivated parameter that can be switched based on service needs, the system optimizes power consumption while preserving the ability to achieve high time synchronization precision when the parameter is set to activated state
2Adaptability or versatility
If a communication device maintains time synchronization packets for multiple clock sources, then adaptability to different service requirements is improved, but device complexity increases
Solution Approach 1:
The patent segments the time synchronization processing into separate manageable components for each clock source. Each clock source can be independently activated or deactivated, allowing the system to handle multiple services without processing all clock sources simultaneously. This segmentation reduces overall device complexity by enabling selective processing rather than managing all synchronization packets uniformly
Solution Approach 2:
The patent implements a universal processing mechanism that handles multiple clock sources through a single unified approach. The same activated/deactivated processing logic applies to all clock sources, allowing the system to maintain adaptability to different service requirements without proportionally increasing complexity. The multi-functional design enables one processing framework to serve multiple purposes

AI summary
This application provides a time synchronization packet processing method and apparatus. The method includes: A terminal device receives first indication information, where the first indication information indicates the terminal device to enter an activation state of time synchronization for a first clock source, or the first indication information indicates the terminal device to enter a deactivation state of time synchronization; and processes a time synchronization packet of the first clock source based on the first indication information. The clock synchronization packet is processed in different manners when the time synchronization of the first clock source is in the activation state and the deactivation state, so that the terminal device can perform processing in different manners when signaling indicates that the clock source is activated or deactivated. For example, when the first clock source is in the deactivation state, the terminal device does not need to perform processing that needs to be performed when the first clock source is in the activation state. Therefore, power consumption of a communication device is reduced, and performance of the communication device is improved.
