1. A method comprising:
receiving, by a session management function (SMF) from a wireless device, a protocol data unit (PDU) session establishment request message comprising a parameter indicating a request for synchronization of multiple service data flows with one another; and
sending, by the SMF to a user plane function (UPF) and based on the parameter, a user plane rule indicating that the UPF performs:
synchronized forwarding of first data packets of each of the multiple service data flows; and
in response to a network entity overload, synchronized discarding of second data packets of the multiple service data flows.
