TSN Clock Information Exchange for Accurate Logical Channel Selection

The patent introduces clock information as an intermediary element that mediates between the TSN service and the mobile communication network. The clock information includes timing data from the TSN network and timing data from the mobile network, allowing the terminal to perform time alignment without requiring complex direct synchronization protocols between the two networks.

The patent performs preliminary action by acquiring and processing clock information before logical channel selection. The terminal obtains clock information from the communication node, performs time alignment based on this information, and then uses the aligned time for logical channel selection. This preliminary time alignment improves subsequent channel selection accuracy without adding complexity during the actual data transmission phase.

The patent applies local quality by providing different types of clock information for different time alignment requirements. The communication node sends multiple types of clock information (first timing data, second timing data, third timing data) that can be selectively used based on the specific service requirements and network conditions, rather than uniformly transmitting all possible synchronization data.

The patent changes parameters by transmitting clock information in different formats and granularities. The system can adjust the level of detail in clock information transmission based on service requirements, allowing flexible parameter adjustment to balance between time alignment accuracy and signaling overhead for different TSN service scenarios.

The patent implements feedback by using service time information (such as arrival time, sending time, and time characteristics) to guide logical channel selection. The terminal continuously monitors time-related parameters of services and uses this feedback to dynamically select appropriate logical channels, ensuring that time-sensitive services are routed through channels with matching time characteristics for optimal resource utilization.

The patent applies dynamics by making logical channel selection adaptive rather than static. The system dynamically adjusts channel selection based on real-time service time information and time characteristics, allowing the network to respond to changing traffic patterns and timing requirements, thereby improving radio resource utilization without requiring complete reconfiguration of the network architecture.
