Abstract

A method of defining ATtention (AT) commands for 5G session management operations is proposed. In one example, the AT command can be a set command for configuring a PDU session establishment procedure. Additional 5G parameters including PDU session ID, Single-Network Slice Selection Assistance Information (S-NSSAI), Service and Session Continuity (SSC) mode, access type, and Reflective QoS (RQ) indication are defined for AT command +CGDCONT to configure the PDU session. In another example, the AT command can be a read command for querying PDU session and QoS flow parameters. Additional 5G parameters including PDU session ID (PSI), QoS flow ID (QFI), S-NASSI, SSC mode, access type, and RQ timer are defined for AT command +CGCONTRDP or +CGSCONTRDP.
