Patent ID: 11039369

Abstract:
A method at enhanced error handling for 5G QoS operations is proposed. A PDU session defines the association between the UE and the data network that provides a PDU connectivity service. Each PDU session is identified by a PDU session ID, and may include multiple QoS flows and QoS rules. Within a PDU session, there should be one and only one default QoS rule. The default QoS rule indication (DQR) and the QoS flow identifier (QFI) of QoS rule should not be changed. When the QoS operation carried by the command message is “Modify existing QoS rule and delete packet filters”, then it is defined as a semantic error in the QoS operation if all the packet filters of a QoS rule are deleted, and the QoS rule is a QoS rule of a PDU session of IPv4, IPv6, IPv4v6, or Ethernet PDU session type.
