Patent number: 11956386Abstract: An emergency report can be made to a plurality of emergency services. Provided is a communication control device 2 housing a subscriber terminal 1, and the communication control device 2 includes: a call control unit 21 that connects an emergency call made from the subscriber terminal 1 to an emergency-call reception switchboard 5; and an outgoing/incoming call inhibition unit 22 that inhibits outgoing/incoming calls from/to the subscriber terminal 1 in a prescribed period, when the emergency call is disconnected by the subscriber terminal 1. The outgoing/incoming call inhibition unit 22: when a call is made from the subscriber terminal 1 in the prescribed period, determines whether the call is an emergency call or a general call; in a case of an emergency call, cancels inhibition for outgoing/incoming calls from/to the subscriber terminal 1 and connects the call by using the call control unit 21; and in a case of a general call, does not connect the call.Type: GrantFiled: November 1, 2019Date of Patent: April 9, 2024Assignee: Nippon Telegraph and Telephone CorporationInventors: Daiki Nakajima, Taichi Osada, Mikio Isawa, Yasuhiro Seki, Hiroaki Matsumura, Shinya Narita

Patent number: 11936500Abstract: An in-vehicle network system deployed in a vehicle includes a plurality of first nodes configured to perform an operation relevant to a first function in the vehicle, a second node configured to perform an operation relevant to a second function different from the first function in the vehicle; and a relay device configured to relay communication between the first nodes and the second node. The relay device is configured to start relay of communication between the first nodes earlier than the relay of communication between the first node and the second node at a time of startup.Type: GrantFiled: December 29, 2020Date of Patent: March 19, 2024Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Shu Ishizuka, Hiroya Ando, Taichi Matsumura, Masashi Amesara, Yutaka Ueda, Toshio Kawamura, Tomomi Kawamura, Yoshifumi Ohmori, Toshio Shimada, Yoshiro Hirata

Patent number: 10668876Abstract: An in-vehicle network system includes a plurality of controllers; a plurality of communication lines connected to the controllers, respectively, a relay device connected to the controllers via the communication lines, and a retention determiner configured to determine whether retention of data occurs in the relay device. The relay device is configured to relay data between the communication lines, and configured to preferentially relay data having a priority equal to or higher than a predetermined priority such that the data reaches the controller that is a transmission destination among the controllers within a first predetermined time when the retention determiner determines that the retention occurs.Type: GrantFiled: October 10, 2017Date of Patent: June 2, 2020Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hiroya Ando, Shu Ishizuka, Taichi Matsumura, Masashi Amesara, Yutaka Ueda, Yoshifumi Ohmori, Toshio Kawamura, Tomomi Kawamura, Toshio Shimada, Yoshiroh Hirata
