Base Station Assigned Public Long Code Mask Generation

The patent changes the parameters used for PLCM generation from traditional ESN-based methods to a new structure incorporating base station ID, sector ID, and mobile station ID. This parameter transformation enables standardized PLCM assignment across different base stations and vendors while maintaining the flexibility to assign unique PLCMs dynamically, thereby reducing algorithm complexity and improving interoperability without sacrificing adaptability.

The patent segments the PLCM into multiple components: base station ID, sector ID, and mobile station ID. This segmentation allows the system to utilize a much larger address space than traditional ESN-based methods, effectively eliminating collision risks due to ESN exhaustion. The segmented structure maintains assignment simplicity while dramatically improving reliability by enabling unique PLCM generation across numerous base stations and mobile stations.

The patent creates a universal PLCM assignment mechanism that works across different vendors and network configurations. By using standardized identifiers (base station ID, sector ID, mobile station ID) that can be implemented by any vendor, the system achieves vendor interoperability while maintaining implementation flexibility. The universal structure allows any base station regardless of vendor to assign PLCMs consistently, eliminating interoperability issues while preserving the flexibility to adapt to different network topologies and configurations.
