1. A method at a Network Repository Function (NRF) for facilitating data forwarding, the method comprising:
receiving, directly or indirectly, from a forwarding User Plane Function (UPF), an HTTP PUT request message comprising a first indicator indicating that a data forwarding function is supported by the forwarding UPF dedicated for data forwarding between a source cell and a target cell of a User Equipment (UE);
receiving from a Session Management Function (SMF) a HTTP GET request message comprising filter criteria included in query parameters which indicate that the SMF searches for a UPF having a data forwarding function; and
transmitting, to the SMF, a HTTP 200 OK response message comprising a validity period, during which the received search result can be cached by the SMF and an array of NF Profile objects that satisfy the filter criteria.
