  • Patent number: 11911257
    Abstract: An implant delivery tube fitting (12) and an implant delivery system. The implant delivery tube fitting (12) is used for loading and delivering an implant, and the implant delivery tube fitting (12) comprises, sequentially from a proximal end to a distal end, an outer tube (122) and a capsule (121). The inner lumen of the capsule (121) is adapted to receive an implant, and the capsule (121) is provided at the distal end of the outer tube (122). The capsule (121) has a telescopic structure, and the outer tube (122) can drive the capsule (121) to make a telescopic movement so that the capsule (121) is lengthened or shortened.

  • Publication number: 20230048268
    Abstract: Embodiments of this application disclose example authentication event processing methods and apparatuses. One example method includes receiving, by a unified data management network element, a second authentication event processing request from an authentication server network element. The unified data management network element can then query an authentication event corresponding to the second information. The unified data management network element can then process the authentication event. The unified data management network element can then send a third authentication event processing request to a unified data repository network element. The unified data management network element can then receive a third authentication event processing response from the unified data repository network element. The unified data management network element can then send a second authentication event processing response to the authentication server network element.

  • Publication number: 20220286464
    Abstract: Example authorization methods and apparatus are described. In one example authorization method, a first network device and a second network device send a first registration request and a second registration request to a third network device, respectively. The first network device further sends a token request to the third network device. The third network device sends a token response including a token to the first network device. The first network device sends a service request including the token to the second network device. In response to determining that the first network device has the permission to access the second network device, the second network device sends a service response to the first network device.

  • Publication number: 20220052989
    Abstract: A communication method and a communications device are provided. The communication method may include a service communication proxy (SCP) that receives a service request from a service consumer, where the service request carries a token, and the token includes a network function (NF) set identifier of a service producer. The SCP sends the service request to a service producer selected from a NF set of the service producer.

  • Publication number: 20210400482
    Abstract: An authentication result update method and a communications apparatus, where the authentication result update method includes: determining that an authentication result of a terminal device in a first serving network needs to be updated; and sending a first service invocation request to an authentication server, where the first service invocation request is used to request to update the authentication result stored in a unified data management device, where visited network spoofing can be prevented after authentication is completed, and where network security can be improved.

  • Patent number: 11096142
    Abstract: A terminal device location determining method and a device. A core network device obtains location information of a terminal device reported by the terminal device and location information reported by a first base station. The core network device determines whether the location information of the terminal device matches the location information reported by the first base station, and if the location information of the terminal device does not match the location information reported by the first base station, the core network device sends a reject message to the terminal device. By determining, through comparison, whether the location information of the terminal device reported by the terminal device matches the location information reported by the base station, it can be determined whether a location of the terminal device is incorrectly determined.

  • Publication number: 20210234929
    Abstract: Embodiments of this application provide a data check method, a data check apparatus, and a storage medium. The data check method includes: obtaining a first counter value and a second counter value, where the first counter value is a value obtained by performing counting by UE during data transmission between the UE and a UPF entity, and the second counter value is a value obtained by performing counting by the UPF entity during the data transmission between the UE and the UPF entity; determining whether the first counter value matches the second counter value; and if the first counter value does not match the second counter value, sending a response message to a session management network element.
