Method of distributing uplink data flow between different access networks in 5G communication system and user equipment using the same

摘要

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.
