Abstract
A packet delay budget (“PDB”) improves quality of service (“QoS”) by providing an accurate delay of packets over a network. PDB includes an access network PDB (“AN PDB”) and a core network PDB (“CN PDB”). Because the PDB can change based on network load, the PDB value is more accurate when the CN PDB is dynamically determined. The dynamic CN PDB can be calculated at the basestation or at the user plane function (“UPF”) and an indication of the dynamic PDB indication can be sent between the basestation and/or the UPF.
Claims14
A method for wireless communication, comprising:
- receiving by a basestation from a User Plane Function (“UPF”), a downlink packet with a first timestamp, the first timestamp being a local timestamp at the UPF;
- calculating, dynamically by the basestation, a Core Network Packet Delay Budget (“CN PDB”) based on the first timestamp;
- and
- communicating, by the basestation, the dynamically calculated CN PDB to the UPF.
A method for wireless communication, comprising:
- receiving, by a User Plane Function (“UPF”) from a basestation, an uplink packet with a first timestamp, the first timestamp being a local timestamp at the basestation;
- calculating, dynamically by the UPF, a Core Network Packet Delay Budget (“CN PDB”) based on the first timestamp;
- and
- communicating, by the UPF, the dynamically calculated CN PDB to the basestation.
A system for wireless communication comprising:
- a User Plane Function (“UPF”) determining a first timestamp according to a first local time at the UPF;
- a basestation communicating with the UPF that dynamically calculates a Core Network Packet Delay Budget (“CN PDB”) based on the first timestamp and a second local timestamp at the basestation;
- and
- a Session Management Function (“SMF”) in communication with the UPF that provides an indication of the dynamically calculated CN PDB to the basestation or the UPF.
