User Plane QOS Bearer Control Method for 5G Fixed Access

Abstract:

Methods relating to an access gateway AGF for managing bearer resources and traffic mapping for QoS flows between the AGF and a CPE or a UE behind a CPE when the AGF provides access to the CPE/UE to a CN (e.g., 5GC) are provided. When the AGF receives a message from 5GC comprising one or more QoS profiles with corresponding QoS flow Identifiers, QFIs, the AGF determines whether it should establish new bearers or use existing bearers for the QFIs, then creates a mapping between each of the corresponding QFIs and a bearer ID of each of the one or more bearers and may indicate the L2/L3 QOS marking to be applied at the bearer level or QoS flow level. The AGF instructs the CPE/UE to create or update the one or more bearers indicating for each bearer identifier the corresponding one or more QFIs.
