Publication number: 20220007264Abstract: To provide a communication control method for control signal management based on a reject cause related to a DN authentication procedure, in particular, other than congestion management. Based on a reject cause value indicating DN authentication failure, transmission of a new PDU session establishment message using a parameter identical to the DNN included in a rejected PDU session establishment message is suppressed. In addition, transmission of a new PDU session establishment message using information identical to the combination of the DNN and the S-NSSAI included in the rejected PDU session establishment message is suppressed.Type: ApplicationFiled: November 1, 2019Publication date: January 6, 2022Inventor: TSUYOSHI TAKAKURA

Patent number: 11190995Abstract: In an IMS emergency call connection of a call which a user equipment cannot recognize as an emergency call, a user equipment transmits to an IMS an IMS emergency call connection signal of the call which the user equipment cannot recognize as the emergency call, and in a case that a reject or redirection message indicating an emergency call connection is received from the IMS, the user equipment determines whether to transmit the IMS emergency call connection signal again to a core network to which the user equipment is connected or whether to transmit the IMS emergency call connection signal again to another core network in the same PLMN. Accordingly, a user equipment, a core network apparatus, a control method to be performed by an IMS apparatus, and the like are provided for the user equipment to connect to a network suitable for an emergency call service in the 5th generation (5G) mobile communication system, which is a next-generation mobile communication system.Type: GrantFiled: June 19, 2018Date of Patent: November 30, 2021Assignees: FG Innovation Company Limited, Sharp Kabushiki KaishaInventors: Tsuyoshi Takakura, Shuichiro Chiba

Patent number: 11190930Abstract: A terminal apparatus or a device in a core network exchanges capability information for each function in a registration procedure or a packet data unit (PDU) session establishment procedure. In user data communication, additional information is added into an uplink packet to implement the terminal apparatus-initiated reflective quality of service (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 the authentication and/or authorization function by a data network (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 the management process such as congestion management for each network slice.Type: GrantFiled: June 19, 2018Date of Patent: November 30, 2021Assignees: SHARP KABUSHIKI KAISHA, FG INNOVATION COMPANY LIMITEDInventors: Yudai Kawasaki, Yasuo Sugawara, Masafumi Aramoto, Tsuyoshi Takakura
