a controller configured for:
in a case that the PDU session type is IPv6 or IPv4v6, and the PDU session establishment request message includes information indicating support of a Multi-homed PDU session using IPv6,
establishing a PDU session to use multiple IPv6 prefixes during the PDU session establishment procedure.
2. The UE according to claim 1 , wherein
the PDU session establishment request message further includes information indicating IPv6 or IPv4v6.
3. The UE according to claim 2 , wherein
the PDU session establishment request message further includes information indicating a Session and Service Continuity (SSC) mode.
4. The UE according to claim 1 , wherein
the PDU session establishment request message further includes information indicating a Session and Service Continuity (SSC) mode.
5. A communication control method performed by a User Equipment (UE), the communication control method comprising:
