Communication Device of Handling Network-based Internet Protocol Flow Mobility

A communication device, communicating with a network apparatus via a packet data network (PDN) connection relying on first and second accesses, the communication device comprising:

• a storage unit for storing instructions of:
• transmitting a first message to the network apparatus, wherein the first message indicates the connected second access and configuration which includes one or more Internet Protocol (IP) flows for transferring between the first access and the second access, wherein the first access is used to access a cellular network, and the second access is used to access a non-cellular network;
• and
• a processing means, coupled to the storage unit, configured to execute the instructions stored in the storage unit.

A network apparatus, communicating with a communication device via a packet data network (PDN) connection simultaneously relying on a first access and a second access, the network apparatus comprising:

• a storage unit for storing instructions of:
• receiving a first message transmitted by the communication device indicating a status of the second access;
• and
• transmitting a second message to the communication device, wherein the second message comprises configuration indicating transferring one or more Internet Protocol (IP) flows between the first access and the second access, wherein the first access is used to access a cellular network, and the second access is used to access a non-cellular network;
• and
• a processing means, coupled to the storage unit, configured to execute the instructions stored in the storage unit.
