MCG Fast Recovery via Secondary Node Forwarding

The patent applies preliminary action by pre-configuring the secondary node (SN) with recovery information before the MCG failure occurs. When failure is detected, the UE can immediately use the pre-configured SN to establish a backup connection without waiting for complex RRC reconfiguration procedures, thus reducing recovery time while maintaining reliability

The secondary node acts as an intermediary in the failure recovery process. Instead of directly reconfiguring the master node through lengthy RRC procedures, the patent uses the SN as a mediator to provide alternative connectivity paths, enabling faster recovery by bypassing the traditional time-consuming reconfiguration process

The patent applies self-service by enabling the UE to autonomously detect MCG failures and initiate recovery procedures without extensive network intervention. The UE monitors its own connection status, detects failures, and triggers the appropriate recovery mechanism, reducing the complexity burden on the network side while maintaining data transmission continuity

The failure recovery mechanism is segmented into distinct functional components: failure detection module, recovery decision module, and execution module. This segmentation allows each component to handle specific tasks independently, reducing overall system complexity while enabling fast and reliable recovery through coordinated action of simplified modules
