  • Publication number: 20230224779
    Abstract: A radio terminal (1) determines that the radio terminal (1) is approaching a first station (5), receives from a center server (4) a cell identifier of a first cell corresponding to an entrance gate function (53) of the first station (5), and transmit a message containing the cell identifier to a cellular communication network. The message causes the network to add the first cell (54) as a secondary cell in dual connectivity for the radio terminal (1), enabling the radio terminal (1) to communicate with the entrance gate function (53) via a user plane path including a radio connection of the first cell (54). The radio terminal (1) then communicates with the entrance gate function (53) via the user plane path. This contributes, for example, to reducing latency required to transmit or receive user data in a narrow coverage cell when a radio terminal receives a signal from that cell.

  • Publication number: 20220295363
    Abstract: A Policy Control Function (PCF) apparatus (34) receives information from a Network Exposure Function (NEF) apparatus (35) or an Application Function (AF) apparatus (41) and modifies based on the information a policy including an Index to RAT/Frequency Selection Priority (RFSP index). This can, for example, contribute to enabling a radio communication network to provide a User Equipment (UE) with a user plane path containing a radio connection in a specific cell based on a request from an AF.

  • Publication number: 20220264679
    Abstract: A User Equipment (UE) (3) includes, in a Non-Access Stratum (NAS) message requesting establishment or modification of a protocol data unit (PDU) session, one or both of a first identifier representing a candidate secondary cell (12) for dual connectivity and a second identifier representing a frequency band in which the candidate secondary cell operates. The UE (3) sends the NAS message to a core network (30) via a radio access network (10). This can, for example, allow a radio communication network to provide a UE with a user plane path that includes a radio connection in a specific secondary cell of dual connectivity based on a request from the UE or an application function.

  • Patent number: 10801521
    Abstract: A heating device for heating a component in a turbo molecular pump for exhausting a gas includes a heat transfer member, a heater, a first seal member and a second seal member. The heat transfer member is provided in an opening of a housing of the turbo molecular pump and has one end fixed to the component and the other end exposed to an outside. The heater in the heat transfer member heats the component through the heat transfer member. The first seal member is provided between the heat transfer member and the opening along an outer peripheral surface of the heat transfer member. The second seal member between the heat transfer member and the opening is located close to the component compared to the first seal member. The second seal member suppresses movement of radicals in a gas into a space between the heat transfer member and the opening.
