Benefits of technology

The patent describes a transfer device and method that allows for the transfer of sound signals between two terminal devices in different communication systems. The device includes a first reception unit for receiving a sound signal from a first terminal device in a first communication system and transmitting it to a second terminal device in a second communication system. The second terminal device then sends a sound signal to the first terminal device. The device also has a storage unit for storing the sound signal received from the first terminal device if the second terminal device is transmitting it. The second transmission unit adjusts the speech speed to match the first transmission unit, and the device detects the reception of the sound signal and sends a control signal to the second terminal device. The technical effect of this invention is to enable seamless communication between devices in different communication systems and adjust speech speed for better user experience.

Problems solved by technology

However, when a radio unit operating in the simplex communication (half duplex) scheme and a telephone unit operating in the complex communication (full duplex) scheme communicate via a base station, the user of the radio unit cannot hear the sound sent from the telephone unit while the radio unit is transmitting a signal.
The terminal device transmitting a sound signal in the business wireless system cannot receive a sound signal, and the terminal device receiving a sound signal cannot transmit a sound signal.
However, users of a mobile communication terminal device are not used to one way communication and so often start talking even while the business wireless terminal device is transmitting a signal.
In particular, the likelihood is high that the user of the mobile communication terminal device starts talking in the middle of transmission from the business wireless terminal device if, for example, a slight break occurs while the user of the business wireless terminal device is talking.
As a result, the user of the business wireless communication device cannot hear the sound originated by the user of the mobile communication terminal device in the middle of transmission from the business wireless terminal device.

embodiment 1

[0025]A brief summary will be given before describing the invention in specific details. Embodiment 1 relates to a transfer device for transferring a sound signal between a first communication system supporting two way communication and a second communication supporting one way communication. For example, the first communication system is a mobile communication system and the second communication system is a business wireless system. In the mobile communication system, two way communication between terminal devices is enabled by using a base station device to assign an upstream channel and a downstream channel to each terminal device. In the business wireless system, a plurality of terminal devices form a group. The base station device assigns an upstream channel and a downstream channel to a group. In this setup, one of the terminal devices in a group (hereinafter, referred to as “transmitting device”) transmits a signal using the upstream channel, and another terminal device in th...

embodiment 2

[0051]A description will now be given of Embodiment 2. Like Embodiment 1, Embodiment 2 relates to a transfer device for transferring a sound signal between a first communication system supporting two way communication and a second communication supporting one way communication. Embodiment 2 is directed to the purpose of letting the user of the terminal device of the business wireless system know that the user of the terminal device of the mobile communication system started talking while the terminal device of the business wireless system is transmitting a signal. For this purpose, when the sound from the terminal device of the mobile communication system is received while the terminal device of the business wireless system is transmitting a signal, the terminal device of the business wireless system is notified accordingly by using the downstream control channel. A prerequisite for this is that the terminal device of the business wireless system can receive a downstream control cha...

Abstract

A first reception unit receives a sound signal destined to a second terminal device in a second communication system supporting one way communication from a first terminal device in a first communication system supporting two way communication. A first transmission unit transmits the sound signal received in the first reception unit to the second terminal device. A second reception unit receives a sound signal destined to the first terminal device from the second terminal device. A second transmission unit transmits the sound signal received in the second reception unit to the first terminal device. A storage unit stores the sound signal received in the first reception unit if the second transmission unit is transmitting the sound signal received in the second reception unit. The first transmission unit transmits the sound signal stored in the storage unit when reception of the sound signal in the second reception unit is completed.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is based upon and claims the benefit of priority from the prior Japanese Patent Application No. 2014-68821, filed on Mar. 28, 2014, the entire contents of which are incorporated herein by reference.BACKGROUND[0002]1. Field[0003]The present invention relates to transfer technology and, more particular, to transfer devices and transfer methods for transferring sound signals in different communication systems.[0004]2. Description of the Related Art[0005]Communication systems that allow communication between a radio unit of a mobile station and a telephone unit connected to a fixed-line telephone network are known (e.g., patent document 1). However, when a radio unit operating in the simplex communication (half duplex) scheme and a telephone unit operating in the complex communication (full duplex) scheme communicate via a base station, the user of the radio unit cannot hear the sound sent from the telephone unit while the rad...
