Abstract: This disclosure describes systems, methods, and devices related to data forwarding tunnel establishment between two user plane functions in fifth generation (5G). A device may determine an association of an access and mobility management function (AMF) with a first radio access network (RAN). The device may identify a handover request message received from the first RAN via the AMF. The device may identify a request to establish an indirect data forwarding associated with the handover, wherein the request is received from the first RAN via the AMF. The device may cause to send a response addressed to the AMF indicating that the indirect data forwarding is established.
