1. A session management apparatus comprising:
a transmitter configured to transmit a request for a report to a user plane apparatus; and
a receiver configured to receive, from the user plane apparatus, a difference of rate of time progress between a clock of an external time domain and a 5G system clock, and identification information of the external time domain,
wherein the transmitter transmits, to a base station apparatus, communication assistance information determined based on the difference of rate of time progress, and
wherein the difference of rate of time progress is a cumulative rate ratio between the clock of the external time domain and the 5G system clock.
