Abstract: Some embodiments of the invention provide a novel method of tunneling data packets. The method establishes a tunnel between a first forwarding element and a second forwarding element. For each data packet directed to the second forwarding element from the first forwarding element, the method encapsulates the data packet with a header that includes a tunnel option. The method then sends the data packet from the first forwarding element to the second forwarding element through the established tunnel. In some embodiments, the data packet is encapsulated using a protocol that is adapted to change with different control plane implementations and the implementations' varying needs for metadata.

Abstract: A method of supporting IMS signaling over EPS bearer or QoS flow upon inter-system change between EPS and 5GS is proposed. When inter-system change from 5GS to EPS occurs, a PDU session is converted to a PDN connection having multiple EPS bearers. The EPS bearer mapped from the QoS flow that is used for IMS signaling in 5GS is the EPS bearer for IMS signaling in EPS. When inter-system change from EPS to 5GS occurs, a PDN connection is converted to a PDU session having multiple QoS flows. The QoS flow that is associated with the default QoS rule is the QoS flow for IMS signaling in 5GS, regardless of which EPS bearer is used for IMS signaling in EPS.

Based on the determined user-plane path, the GW-U can forward the IP packet to a local application server (AS), encapsulate and forward the IP packet to the PGW, or discard the IP packet. Moreover, the GW-U can encode the IP packet for transmission based on the determined user-plane selection.
