1Productivity
If traditional roaming registration methods are used between compact core systems and central core network systems, then compatibility and connectivity can be achieved, but resource consumption increases and network congestion occurs due to translation computations and lack of automated identification
Solution Approach 1:
The compact core system performs self-identification by autonomously generating and transmitting its identifier (e.g., compact AMF identifier) to the central core network system during registration. This eliminates the need for external translation computations or intermediary services, allowing the system to register itself efficiently without consuming additional network resources for translation processes
Solution Approach 2:
The invention extracts and removes the unnecessary translation computation step from the traditional roaming registration process. By directly using the compact core system's identifier without translation, the patent eliminates this redundant processing step, reducing computational resource consumption and preventing network congestion while maintaining registration functionality
2Reliability
If secure communication is implemented between compact core systems and central core network systems, then data security is enhanced, but system complexity increases due to additional security mechanisms
Solution Approach 1:
Security parameters and configurations are pre-established and stored in the compact core system before actual communication occurs. The system prepares security credentials and encryption parameters in advance, so that when communication with the central core network system is initiated, secure transmission is automatically enabled without requiring complex real-time security negotiation or additional computational overhead during operation

AI summary
A method implemented in a communication network between a compact core system and a central core network system for registration and session management comprises transmitting, by a compact access and mobility management function (AMF) at the compact core system, a registration request to the central core network system, in which the registration request comprises data associated with the compact core system, and completing, by a central AMF at the central core network system, a registration of the compact core system by adding the data associated with the compact core system at a registration data store in the central core network system, and establishing, using a user plane function (UPF) at the compact core system, a connection between the compact AMF and a central AMF at the central core network system over a network slice.
