[0023] Fig. 1 is a schematic configuration view of an IP telephone system involved in a first embodiment of the present invention.

[0024] The system includes an IP network IPN for packet communication. The IP network IPN is established at a location such as an office or a residence. The IP telephone terminals T11 and T1i (which are integers) are connected in the office, and the IP telephone terminal T21 is connected in the house. In this embodiment, the user moves from the office to the home, and uses the IP telephone terminal T21 at the home with the same extension number (connection ID) as the IP telephone terminal T11 (source) working in the office. In addition, the IP telephone terminals T11 to T1i and T21 include a communication processing function and a media information processing function such as images.

[0025] In addition, the IP telephone terminals T11 to T1i and T21 are connected to a key telephone device BT serving as a telephone switching device through an I...

[0051] As a second embodiment of the present invention, FIG. 8 is a diagram illustrating the connection between the key telephone device BT and the IP telephone when the IP telephone terminal T21 disconnects its connection with the key telephone device BT, and the IP telephone terminal T11 reconnects with the key telephone device BT. Sequence diagram of transmission / reception operation of information between terminals T11 and T21. FIG. 9 is a flowchart illustrating a control processing procedure of the key telephone apparatus BT and the IP telephone terminals T11 and T21.

[0052] Assume that the IP telephone terminal T21 is currently connected to the key telephone device BT, and the user performs an operation to request disconnection from the key telephone device BT, ie, a logout operation at the IP telephone terminal T21.

[0053] In this case, the IP telephone terminal T21 sends a logout request to the key telephone device BT (block ST5a). As a result, the IP telephone ter...

[0060] As a third embodiment of the present invention, FIG. 10 shows a sequence diagram showing that when the IP telephone terminal T21 is connected, the new IP telephone terminal T31 tries to establish a connection with the key telephone terminal with the same extension number "DN2000". In the case of connection, the transmission / reception operation of information between the key telephone apparatus BT and the IP telephone terminals T11, T21 and T31.

[0061] Assume that the IP telephone terminal T21 is currently connected to the key telephone device BT, and the user performs a login operation to the key telephone device BT by using the IP telephone terminal T31 of the extension number "DN2000".

[0062] In this operation, the IP telephone terminal T31 sends a login request to the key telephone device BT. As a result, the IP telephone terminal T31 enters a login waiting state. The above login request includes the identification data of the IP telephone terminal T31 and the e...

Abstract

According to one embodiment, a telephone exchange apparatus which accommodates a plurality of telephone terminals includes a memory(14) to store a management table wherein a terminal identification data (terminal ID) and a connection identification data (connection ID) correspond to an operation data indicating a connected / disconnect status with respect to each of the plurality of telephone terminals, and a controller(13) to connect communication between the plurality of telephone terminals in operation based on the management table, and to update the operation data corresponding to the terminal ID of the relevant telephone terminal within the management table based on a predetermined condition.

Description

technical field [0001] One embodiment of the present invention relates to a telephone switching device for connecting communication between telephone terminals through an IP network, such as an IP (Internet Protocol) telephone system. Background technique [0002] In recent years, an Internet telephone system (IP telephone system) that interactively transmits / receives images and voice over a packet network as real-time packet data has been widely used. In this IP telephone system, voice communication can be performed between IP telephone terminals connected to a packet network, while voice communication can be performed between an IP telephone terminal and a telephone terminal connected to a public network. [0003] In the above-mentioned IP telephone system, the extension number of each of a plurality of IP telephone terminals connected to the packet network is controlled by the telephone switching equipment. However, it is highly desirable to establish voice communication...
