Abstract:
A method of defining ATtention (AT) commands for supporting Service and Session Continuity (SSC) mode 2 and SSC mode 3 of 5G Protocol Data Unit (PDU) session operations is proposed. The AT command can be a notification of an unsolicited result code +CGEV: NW PDN DEACT, +CGEV: NW MODIFY, or +CGEV: ME PDN ACT, or a configuration command +CGDCONT with additional 5G parameters. Additional 5G parameters include an SSC, an old CID, a change reason and a PDU lifetime for the purpose of communicating information regarding the request of PDU session anchor relocation.
