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.

Abstract: A ride-sharing system can automatically and autonomously determine whether a rider is an account holder associated with an account of a ride-sharing service that requested a ride or a guest rider. A guest rider detection system can use geolocation data to determine whether a rider is a guest rider or an account holder. The system can obtain location data for an account holder that requests a ride using a ride sharing application. The location data of the account holder can be compared with one or more locations (e.g., pickup or drop off location) associated with the requested ride. Based at least in part on the comparisons between the location data of the account holder and the one or more locations associated with the requested ride, the system can determine with a particular degree of certainty whether the rider is the guest rider or the account holder.
