A recognition analysis processing unit (20) analyzes call voice information about a call between terminals, which are in a communicating state, specifies a language used in the call voice information, and stores the language as language information. When a hold request detection unit (11) detects a hold request signal for requesting that the call to be held transmitted from one of the call originating terminal and the call receiving terminal, which are in the communicating state, to be held, it extracts, from the language information stored in the recognition analysis processing unit (20), the language used in the call between the terminals to which the hold request signal has been transmitted from the one of the terminals, selects, from a hold tone database (30) storing the hold tones including a plurality of on-hold messages in various languages, the hold tone including the on-hold message in the language matching the extracted language, and transmits the selected hold tone to another one of the terminals, which is another party on the phone. Thus, a telephone exchange (1000) for making the other party on the phone listen to the hold tone including the on-hold message in the language matching the language used by the other party on the phone is provided.

There is provided an inter-main-apparatus interface device which, even if a first-standard main apparatus and a second-standard main apparatus are gathered in a main apparatus system, enables both of main apparatuses to function normally. The device comprises a control data interface provided between the first-standard main apparatus and the second-standard main apparatus for operating a controller included in the second-standard main apparatus on the basis of control data supplied from the first-standard main apparatus, and a content data interface provided between the first-standard main apparatus and the second-standard main apparatus for enabling the second-standard main apparatus, as controlled by the controller operating on the basis of the control data, to relay by multiplexing and demultiplexing, content data sent and received by a base station connected to the first-standard main apparatus and content data sent and received by a base station connected to the second-standard main apparatus.

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.

The present disclosure improves security in a technology for unlocking an electronic lock using a door phone slave unit. A business phone main unit (2) includes: a PB signal reception unit (22) that receives a PB signal input through a door phone slave unit (5); an authentication information decoding unit (23) that decodes authentication information from a PB signal; and an electronic lock control unit (25) that controls an electronic lock (4) based on the decoded authentication information.

A Non-Geostationary Satellite Orbit (NGSO) satellite system is described that implements one or more user route tables and a plurality of pre-calculated backbone route tables at its satellites. The user route tables track user connectivity to the satellites, and each of the backbone route tables defines a snapshot of a time-varying backbone topology seen by a particular satellite. During operation, a satellite selects different backbone route tables as the topology changes over time, and receives updates to the user route tables when connectivity changes occur between the users and the satellites. The decoupling of the user route tables from the backbone route tables at the satellite reduces the computational burden on the NGSO system, as the backbone route tables are calculated in advance and the NGSO system is subsequently tasked with a computationally lower burden of performing real-time updates to the user route tables.

An incoming call controlling device (2) includes a connection determining unit (3) configured to determine, when an incoming call to a first phone number is received, whether a mobile phone terminal (6) is connected as an extension phone to the incoming call controlling device (2); an incoming call controlling unit (4) configured to transfer the incoming call to a second phone number when it has been determined that the mobile phone terminal (6) is not connected to the incoming call controlling device (2); and a caller information transmitting unit (5) configured to transmit, to a server (7), identification information and caller information of the incoming call when a transfer by the incoming call controlling unit (4) is performed. The server (7) is configured to notify a phone terminal of the caller information by using a network different from a circuit used for the transfer.
