  • Patent number: 10972956
    Abstract: A method of QoS rule management with enhanced handling on QoS flow description is proposed. UE checks QoS configuration received from the network for QoS operation errors. When UE receives a QoS rule associated with a specific QFI but has no QoS flow description for the QFI, UE further determines whether the QoS rule is of a GBR QoS flow. If so, UE detects a QoS operation error. If the QoS rule is the default QoS rule, then UE releases the PDU session. If the QoS rule is not the default QoS rule, then UE either rejects a PDU session modification command that carries the QoS rule or deletes the QoS rule carried by a PDU session establishment accept with a 5GSM cause value indicating the QoS operation error.

    Abstract: Aspects of the disclosure provide an electronic apparatus and a method for wireless communication. The electronic apparatus can include processing circuitry. The processing circuitry can send one or more packet data unit (PDU) session release requests to a wireless communication network system to request a PDU session release procedure. In an embodiment, a timer is used for the one or more PDU session release requests. The processing circuitry can determine whether a network response is received from the wireless communication network system before the timer expires and whether a number of times that the timer expires reaches a predetermined number of times. The processing circuitry can locally release the PDU session when the network response is not received and the number of times that the timer expires reaches the predefined number of times.
