  • Patent number: 11723100
    Abstract: A terminal apparatus or a device in a core network exchanges capability information for each function in a registration procedure or a PDU session establishment procedure, and in user data communication additional information is added into an uplink packet to implement terminal apparatus-initiated RQoS control, and additional information is added into a downlink packet to implement network device-initiated RQoS control. A dedicated control message and information for an authentication and/or authorization function by a DN are defined to implement the authentication and/or authorization function by the DN. Furthermore, the terminal apparatus and the device in the core network have a timer or a control process for each network slice to implement a management process such as congestion management for each network slice.

  • Publication number: 20230115813
    Abstract: A UE receives, from a first base station apparatus, system information and/or a registration accept message including a first frequency band supported by the first base station apparatus, first S-NSSAI corresponding to a first frequency band, a second frequency band supported by a second base station apparatus, and second S-NSSAI corresponding to a second frequency band. The UE recognizes that a registration request message and/or a PDU session establishment request message including the second S-NSSAI is not transmittable via the first base station apparatus, and in a case of reselecting a cell of the second base station apparatus, recognizes that the registration request message and/or the PDU session establishment request message including the first S-NSSAI is not transmittable via the second base station apparatus. This prevents, in a 5 GS, transmission of a registration request message and/or PDU session establishment request message which is unnecessary.

  • Publication number: 20230053127
    Abstract: A UE transmits a PDU session establishment request message including an S-NSSAI and a PDU session ID, and receives a PDU session establishment accept message including the S-NSSAI, the PDU session ID, a first cause value, a first back-off timer value, a first Session-AMBR IE, and a second Session-AMBR IE. The UE establishes a PDU session corresponding to the S-NSSAI, configures a back-off timer corresponding to the S-NSSAI to the first back-off timer value, and applies a data rate indicated by the second Session-AMBR IE to the PDU session while the back-off timer is running.

  • Publication number: 20220377693
    Abstract: A UE transmits a registration request message including an S-NSSAI and receives a registration accept message including the S-NSSAI, a first cause value, and a first back-off timer value. The UE starts a back-off timer using the first back-off timer value corresponding to the S-NSSAI. In a case that the UE receives a configuration update command including the S-NSSAI, a second cause value, and a second back-off timer value before expiration of the back-off timer, the UE updates, in a case that the second back-off timer value indicates a value other than zero the back-off timer to be the second back-off timer value and stops, in a case that the second back-off timer value indicates zero, the back-off timer. In a case that the back-off timer expires or stops, the UE transmits the registration request message including the S-NSSAI or a PDU session establishment request message.

    Abstract: According to one aspect of the present invention, a communication unit for realizing a function for ATSSS in a 5GS is provided. A UE transmits a PDU session establishment request message including an MA PDU Request indication and ATSSS Capability, and in a case that an MA PDU session is allowed to be established and that only the user plane resources for one of 3GPP access or non-3GPP access are allowed to be established, the UE receives information indicating that the MA PDU session is allowed to be established, an access type corresponding to the user plane resources allowed to be established, a value indicating a cause of disallowance of establishment of the user plane resource for an access type different from the above-described access type, and a PDU session establishment accept message including ATSSS rules, and establishes the MA PDU session.
