Relaying device

摘要

The present invention relates to a relaying device which performs the individual calling in response to not only a call incoming from a telephone but also a call incoming from a transceiver. When receiving a communication request from another device over a network, the relaying device determines if this communication request is accompanied by the wireless-device specifying information (ID). When the communication request is not accompanied by the ID, the relaying device sends a signal for prompting another device to input the ID. When the ID is sent in response to the sent signal, the relaying device instructs the relaying wireless device to call the wireless terminal device specified by this ID. In addition, when the communication request is accompanied by the ID, the relaying device instructs the relaying wireless device to call the wireless terminal device specified by this ID.

主权项

1. A relaying device comprising:
a wireless device interface to which a relaying wireless device is connected, wherein the relaying wireless device communicates with more than one wireless terminal devices; a network interface connected to a data communication network and receiving a communication request and wireless-device specifying information for specifying one of the wireless terminal devices from a partner device connected to the data communication network; and a control unit connected to the wireless device interface and the network interface, wherein the control unit determines whether or not the communication request is accompanied by the wireless-device specifying information, when receiving the communication request, when the communication request is not accompanied by the wireless-device specifying information, the control unit sends a signal prompting an input of the wireless-device specifying information to the partner device, and after the partner device sends the wireless-device specifying information in response to the signal, the control unit instructs the relaying wireless device to call the wireless terminal device specified by the wireless-device specifying information, when the communication request is accompanied by the wireless-device specifying information, the control unit instructs the relaying wireless device to call the wireless terminal device specified by the wireless-device specifying information, the communication request is an INVITE message of SIP protocol, and the wireless-device specifying information is embedded into a TO header.
