Systems and methods for transferring multiple packet data unit sessions with a same data network name configuration between networks

A network device, comprising:

• one or more processors configured to:
• receive an indication of movement of a user device, associated with multiple packet data unit (PDU) sessions, from a first radio access network (RAN) to a second RAN,
• wherein the multiple PDU sessions are associated with a same data network name configuration;
• maintain, based on the indication, a particular PDU session, of the multiple PDU sessions, associated with a default flow;
• release, based on the indication, the multiple PDU sessions other than the particular PDU session;
• and
• handle the multiple PDU sessions, other than the particular PDU session, in accordance with a handling option.

A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of a network device, cause the network device to:
• receive an indication of movement of a user device, associated with multiple packet data unit (PDU) sessions, from a first radio access network (RAN) to a second RAN;
• maintain, based on the indication, a particular PDU session, of the multiple PDU sessions, associated with a default flow;
• release, based on the indication, the multiple PDU sessions other than the particular PDU session;
• cause the user device to perform an interworking handover from the first RAN to the second RAN;
• and
• handle the multiple PDU sessions, other than the particular PDU session, in accordance with a handling option.
