Patent number: 11044362Abstract: Terminal information of a mobile terminal via the Internet is transmitted, and an outgoing reservation is made. Along with this, terminal information of a mobile terminal is transmitted from a telephone network to a telephone exchange apparatus of a company. The telephone exchange apparatus checks the terminal information of a call originator mobile terminal for which an outgoing call is reserved via the Internet against call originating terminal information arrived via the telephone network, and when the call originator terminal information arrived via the telephone network can be authenticated, the reserved call destination terminal is called with the company exchange apparatus as a call originator. When a user calls a customer from his/her mobile terminal phone, a telephone number of the personal mobile terminal is not displayed on a call destination terminal. Further, no troublesome operation for callback is required, and the communication cost charged to a company is reduced.Type: GrantFiled: October 4, 2017Date of Patent: June 22, 2021Assignees: NEC Platforms, Ltd., NIPPON TELEGRAPH AND TELEPHONE EAST CORPORATION, NIPPON TELEGRAPH AND TELEPHONE WEST CORPORATIONInventors: Hideo Maki, Takashi Ando, Yasuaki Kaneda

Patent number: 10135998Abstract: A key telephone system includes a terminal and a primary device. The primary device transmits a command for transition into a power-saving state to the terminal, together with a power-saving duration time datum and/or a power-saving deactivating time datum, when the time reaches a power-saving state transition time. The terminal specifies the power-saving duration time and/or the power-saving deactivating time in the timekeeper means, and halts the communication means for communicating with the primary device at the time of receiving the command for transition into the power-saving state from the primary device, and activates the communication means being halted at a time when the timekeeper means has measured the lapse of the power-saving duration time and/or the power-saving deactivating time.Type: GrantFiled: April 30, 2014Date of Patent: November 20, 2018Assignees: NEC Platforms, Ltd., NIPPON TELEGRAPH AND TELEPHONE EAST CORPORATION, NIPPON TELEGRAPH AND TELEPHONE WEST CORPORATIONInventors: Hideo Maki, Norio Murakami, Shozo Shikenya, Tetsuya Takekawa, Daisuke Iwata
