The N16 interface is a communication interface for transmitting session signaling between any two session management function network elements in the 5G core network. Session signaling can be signaling for creating a protocol data unit session, signaling for modifying a protocol data unit session, or signaling for releasing a protocol data unit session. A protocol data unit session refers to the process of communication between a user terminal and a data network. After a protocol data unit session is established, a data transmission channel between a user terminal and a data network is established.
