Multi-Link Parameter Update Signaling for Non-Primary Access Links

The patent introduces an intermediary mechanism where the primary link acts as a mediator to convey system parameter update information to non-primary links. Instead of requiring each non-primary link to independently broadcast parameters, the primary link transmits update indicators and parameters to connected terminal devices, which then forward this information to non-primary links. This intermediary approach maintains broadcast simplicity while enabling efficient parameter propagation across all links.

The patent implements periodic action by introducing a parameter update indicator mechanism that triggers broadcasts only when system parameters actually change. Instead of sending frequent periodic broadcasts regardless of content changes, the system uses the update indicator to signal terminal devices to forward parameter information only when necessary. This reduces unnecessary signaling overhead while ensuring parameter timeliness through event-driven updates.

The patent extracts the monitoring burden from terminal devices by centralizing parameter change detection at the access device level. The access device monitors system parameter changes on all links and uses update indicators to trigger selective forwarding to terminal devices. This extraction approach maintains parameter acquisition timeliness while significantly reducing terminal device complexity and power consumption, as terminals only need to respond to update indicators rather than continuously monitor all links.
