NB-IoT Carrier Deployment Mode Configuration for Network Compatibility

The patent segments the carrier configuration information into two distinct parts: a first carrier configuration containing first configuration information for new deployment modes, and a second carrier configuration containing second configuration information for conventional deployment modes. This segmentation allows the network to provide different configuration sets without forcing existing terminals to handle incompatible new modes, thus maintaining backward compatibility while enabling new deployment options.

The patent makes the carrier configuration universal by supporting multiple deployment mode combinations through two configuration sets. The first carrier configuration can support new deployment modes for advanced terminals, while the second carrier configuration ensures compatibility with existing terminals. This multi-functionality allows the same NB-IoT system to serve both legacy and advanced terminals simultaneously with different carrier deployment combinations.

The patent divides the configuration information into two separate carrier configurations, each with its own set of deployment mode combinations. This segmentation prevents existing terminals from needing to process complex new deployment modes, as they can rely on the second carrier configuration with conventional modes, thereby avoiding increased terminal complexity while still enabling network adaptability.

The patent implements partial action by providing two carrier configurations where only advanced terminals need to process the first configuration with new deployment modes. Existing terminals can function normally using the second configuration with conventional modes. This partial implementation allows the network to prepare for future advanced terminals without forcing complexity on all terminals.
