1. A method of jitter monitoring for time sensitive communication in a wireless communication network, the method comprising:
receiving, by a user plane function (UPF), a delay and jitter measurement request from an application function (AF);
measuring, by the UPF, a delay and a jitter in response to the delay and jitter measurement request; and
transmitting, by the UPF, the measured delay and jitter to the AF,
wherein the delay is determined based on a difference between a time when the UPF transmits data and a time at which a user equipment (UE) receives the data,
wherein the jitter is determined based on at least one of a maximum difference between a measured delay value and a mean delay value in a set of delay measurements, and a variance value of the set of delay measurements,
wherein the UPF is configured for Quality of Service (QOS) monitoring including measuring of the delay and the jitter, and for reporting based on a reporting frequency;
wherein the reporting frequency is configurable for event-triggered reporting, such that if the measured jitter exceeds a predetermined jitter threshold value, the UPF reports the measured jitter to the AF based on the event-triggered reporting; and
wherein the reporting frequency is also configurable for periodic reporting based on a predetermined measurement period.
