20 Claims

1. An apparatus comprising a user plane function (“UPF”),

the apparatus comprising:

at least one memory; and

at least one processor coupled with the at least one memory and configured to cause the UPF to:

receive a request to monitor a quality of service (“QoS”) parameter for a data connection of a user equipment (“UE”), wherein the QoS parameter is associated with a packet delay measurement;

modify a downlink packet to include an indication for a QoS monitoring report;

receive a QoS monitoring result from an access network node in response to the modified downlink packet; and

determine a value of the QoS parameter based on an amount of time expired between a transmission of the modified downlink packet and a reception of the QoS monitoring result, and a subtraction of one half of a delay between the access network node and the UPF.
