PDU sessions with various types of session continuity

A method of a network node, the method comprising:

• provisioning a user equipment (“UE”) device with a continuity selection policy comprising at least one prioritized rule for selecting a data session continuity type from a plurality of data session continuity types supported by a mobile communication network based on at least one characteristic of a request to establish a data session, wherein the plurality of data session continuity types comprises:
• a first continuity type requiring a fixed mobility anchor,
• a second continuity type that does not require a fixed mobility anchor, that maintains an initial network address for a period of time after receiving a successive network address and that releases the initial address after the period of time, and
• a third continuity type that does not require a fixed mobility anchor;
• receiving a request to establish a data session from the UE device, wherein the request specifies a particular data session continuity type;
• and
• establishing a first data connection with the UE device in response to the request, the first data connection having the particular data session continuity type, the first data connection comprising a protocol data unit (“PDU”) session between the UE device and the mobile communication network.

A user equipment (“UE”) apparatus comprising:

• a transceiver that:
• receives a continuity selection policy comprising at least one prioritized rule for selecting a data session continuity type from a plurality of data session continuity types supported by a mobile communication network based on at least one characteristic of a request to establish a data session, wherein the plurality of data session continuity types comprises:
• a first continuity type requiring a fixed mobility anchor,
• a second continuity type that does not require a fixed mobility anchor, that maintains an initial network address for a period of time after receiving a successive network address and that releases the initial address after the period of time, and
• a third continuity type that does not require a fixed mobility anchor;
• and
• sends a request to establish a data session from the UE device, wherein the request specifies a particular data session continuity type;
• and
• a processor that establishes a first data connection via the mobile communication network in response to the request, the first data connection having the particular data session continuity type, the first data connection comprising a protocol data unit (“PDU”) session between the UE device and the mobile communication network.
