XRM Service Processing With TSCTSF Delay Synchronization

The patent introduces a time-sensitive communication and time synchronization function (TSCTSF) as an intermediary component between the application function and the policy control function. This mediator specifically handles synchronization indications and XRM group identifiers, coordinating multiple data flows without requiring complex changes to existing network elements. The TSCTSF acts as a specialized intermediary that bridges the gap between application requirements and network resource management, improving synchronization precision while maintaining acceptable device complexity.

The patent segments the policy control function into specialized components: the TSCTSF module that handles time-sensitive synchronization, and the PCC rule generation module that manages resource allocation. By dividing the control function into dedicated modules with specific responsibilities, the system achieves better synchronization precision for media flows while keeping each module's complexity manageable and well-defined.

The patent applies local quality by implementing synchronization control selectively based on the synchronization indication and XRM group identifier. Not all data flows receive the same level of processing - only those marked with synchronization requirements and belonging to specific XRM groups undergo strict synchronization control. This localized approach ensures high service quality for critical flows while avoiding unnecessary processing overhead for other flows, thereby improving reliability without proportionally increasing network processing complexity.

The patent changes the parameter state of data flows by introducing synchronization indications and XRM group identifiers that modify how flows are processed. These parameter changes enable the network to dynamically adjust processing intensity - flows with synchronization requirements receive enhanced handling, while others follow standard procedures. This parameter-based differentiation improves service quality for time-sensitive flows without uniformly increasing processing complexity across all traffic.

The patent merges the processing of multiple related data flows by grouping them under common XRM group identifiers. Flows belonging to the same XRM group are coordinated through the TSCTSF, which ensures they receive synchronized treatment despite being processed through the network infrastructure. This merging approach maintains individual flow speeds while minimizing delay differences between related flows, as they share common synchronization points and resource allocation policies.

The patent implements feedback mechanisms where the TSCTSF monitors the status of multiple data flows and adjusts resource allocation dynamically. By continuously receiving information about flow status, delay conditions, and synchronization requirements, the system can reallocate network resources to compensate for delay differences. This feedback loop maintains high transmission speeds while actively managing and reducing delay variations between synchronized flows.
