In an aspect, the disclosure provides a method for distributing uplink data flow between different access networks in a 5G communication system. The method would include not limited to maintaining an ATSSS rules table; receiving a request to establish an uplink data flow to a DN; determining from the ATSSS rule table whether the DN is in the ATSSS rule table in response to receiving the request to establish the uplink data flow to the DN; selecting a first PDU session from the ATSSS rule table for the uplink data flow to the DN in response to having been determined that the DN is in the ATSSS rule table; and creating a second PDU session for the uplink data flow to the DN and recording the second PDU session in the ATSSS rule table in response to having been determined that the DN is not in the ATSSS rule table.

A user equipment registration method for network slice selection, and a network controller and a network communication system are provided. The method includes: receiving a registration request of a UE; in response to receiving the registration request including slice selection information, determining whether having a capability for serving the UE according to the slice selection information, so as to transmit a first network function discovery request including the slice selection information or transmit a second network function discovery request for searching a target AMF; and selecting a network function for serving the UE according to a network function discovery response to perform a registration setting operation after receiving the network function discovery response corresponding to the first network function discovery request, or transmitting an interface connection release message to an access node after receiving another network function discovery response corresponding to the second network function discovery request.

A method for network sharing of multiple network operators includes steps of: providing a network sharing management proxy device adapted to be disposed between a sharing access point (AP) and a plurality of core networks of the network operators, wherein the sharing AP allows one or more end user equipment (UE) of the network operators to access; receiving a control message by the network sharing management proxy device, wherein the control message is corresponding to an UE, and the UE is an end UE of a first network operator of the network operators; checking the control message to determine that the UE is corresponding to which one of the network operators, and generating tunneling information accordingly; and transmitting the control message to a first core network of the first network operator according to the tunneling information.
