NR MBS Service Handling Through MCCH Idle/Inactive Configuration

The patent applies preliminary action by pre-configuring MCCH parameters and establishing configuration mechanisms before UE enters idle/inactive mode. The network side pre-provides MCCH configuration information including timing, frequency, and content parameters, allowing UE to efficiently acquire and process MBS service data without complex real-time configuration procedures when transitioning between modes.

The patent applies universality by designing a unified MCCH configuration mechanism that serves multiple functions: it provides configuration for both idle mode and inactive mode UEs, supports both multicast and broadcast services, and enables seamless transitions between different operational modes. This multi-functional approach simplifies UE operation while managing standardization complexity through a single comprehensive framework.

The patent applies segmentation by dividing MCCH configuration into distinct parameters: timing parameters (periodicity, offset), frequency parameters (carrier frequency, bandwidth), content parameters (service list, session info), and control parameters (modification timing). This structured segmentation allows reliable transmission of essential configuration data while minimizing unnecessary signaling overhead by transmitting only the necessary segmented parameters rather than complete configuration datasets.
