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
