6.2.11 Multi-homed IPv6 PDU session

Taught in 4. Inside TS 24.501, the document at the centre (CT1 — the group that writes what your phone says, overview).

The UE supporting IPv6 may support multi-homed IPv6 PDU session.

If the UE supports the multi-homed IPv6 PDU session:

  • the UE shall support acting as a type C host as specified in IETF RFC 4191 [36]; and
  • the UE indicates support of the multi-homed IPv6 PDU session:
    • during the UE-requested PDU session establishment of a PDU session of "IPv6" or "IPv4v6" PDU session type; and
    • during the UE-requested PDU session modification performed after an inter-system change from S1 mode to N1 mode, for a PDU session associated with a PDN connection established when in S1 mode, if the UE is a UE operating in single-registration mode in a network supporting N26 interface, the PDU session is of "IPv6" or "IPv4v6" PDU session type, and the UE has not previously successfully performed the UE-requested PDU session modification to provide this indication.
