Inventors include Landais, Bruno; Gkellas, Georgios; and Thibaut, Laurent.
The application for the patent was published on September 25, 2026, under issue no. 39/2026.
Abstract: The present disclosure describes a method and apparatus for a user plane function (UPF) to provide data to a user equipment (UE) that includes receiving, from a session management function (SMF), rules associated with a packet forwarding control protocol (PFCP) session of a multi-access protocol data unit (MA-PDU) session in which a 5G core (5GC) access path connects a first access of the UE to the UPF via a 5GC and an evolved packet core (EPC) access path connects a second access of the UE to the UPF via an EPC, receiving a data packet from a data network, the data packet associated with the PFCP session of the MA-PDU session, determining which the 5GC access path or the EPC access path is to be used to transmit the data packet to the UE, when the 5GC access path is to be used to transmit the data packet, inserting 5GC-specific information in a header associated with the data packet and transmitting the data packet, with the 5GC-specific information, via the 5GC access path, and when the EPC access path is to be used to transmit the data packet, transmitting the data packet via the EPC access path, wherein the header associated with the data packet transmitted via the EPC access path does not include the 5GC-specific information.
