Description

  The present invention relates to a relay method and apparatus for distributing incoming calls from an IP network to connection destinations based on call information.

  In the conventional telephone system, the receiving terminal is assigned by the telephone number of the incoming call in the relay device.

  This is because it is determined whether the incoming call number acquired from the incoming message from the calling telephone terminal is registered in the incoming call management table provided in the storage unit of the relay device, and when the corresponding destination is registered The destination telephone is called (Patent Document 1).

  As shown in FIG. 4A, the incoming call number and the incoming call destination are associated and stored in the incoming call destination discrimination table (incoming call management table) 311 of the relay device 300, and the terminal C303 and the terminal D304 send "050-AAAAA-AAAAA". ”Is obtained by the incoming call number recognition means 310 so that the called party is not the terminal B302 but the terminal A301 and is connected to the terminal A301.

Further, as shown in FIG. 4B, if the caller ID and the callee are stored in the callee discrimination table (calling management table) 311 ′ in association with each other, if the call is made from the terminal D304, the caller ID of the terminal D304 is stored. Is “050-DDDD-DDDD”, the called number identification unit 310 ′ searches the called party determination table 311 ′ and is connected to the terminal B302.

Unit (call connection information recognition unit) 205, connection destination determination unit 207 that determines a terminal to be connected based on a result analyzed by reception information analysis unit (call connection information recognition unit) 205, and connection destination determination unit 207 A connection destination distribution unit 209 that distributes signals based on the determination result, a connection terminal determination unit 211 that determines a terminal connected to the relay device 100, a data link termination unit b213, and a terminal connection to which the terminal A10 is connected Interface a215, data link termination c217, terminal connection interface b219, data link termination n221, terminal connection in Is provided with a face n223, the.

  The data link termination units b, c,..., N and the terminal connection interfaces a, b,..., N are the number of terminals that can be connected to the relay device 100.

  The reception information analysis unit 205 analyzes the media type, media transmission / reception direction, and route information based on the received SIP message.

  That is, the media type is stored in the media type table 121 as described above. (1) Voice-only communication: When only voice is received using a mobile phone or a videophone, (2) Incoming video only: When only video is received using a mobile phone, videophone, or personal computer, (3) Audio / Video communication: Incoming voice and video incoming from a mobile phone, videophone, or PC .

  In addition, the direction of media transmission / reception is as follows: (1) Transmission / reception communication: When receiving communication from a mobile phone or videophone, etc., and performing bidirectional communication, etc. (2) Transmission only communication: mobile phone, personal computer, TV When a message or image is transmitted from a telephone or the like, (3) Communication only for reception: When a message or image is received from a mobile phone, a personal computer, a videophone or the like.

  Further, the route information includes (1) IP-IP incoming call, (2) PSTN (public switched telephone network) incoming call, (3) voice incoming call via terminal C12 (mobile phone), (4) video It is information that distinguishes from incoming terminal C12 (mobile phone) via a gateway, (5) direct incoming without route information, and the like.

  The connection destination determination unit 207 determines the connection destination obtained from the reception signal by the reception information analysis unit 205.

  The connection destination allocating unit 209 connects (distributes) the received signal to each terminal, which is the connection destination determined by the connection destination determining unit 207, in a communicable manner.

  The connection terminal determination unit 211 associates each terminal connected to the relay device 100 with the connection destination determined by the connection destination determination unit 207.

  Next, the case where the relay device 100 according to the present embodiment determines a connection terminal using call information will be described with reference to the flowchart of FIG.

  First, the terminal C12 and the terminal D13 from the outside make a call to one number (step S1).

  Next, the signal from the terminal C12 and the terminal D13 is received (step S2).

  Next, the received information analysis unit 205 analyzes which of the terminals A10 to n connected to a plurality of received signals is connected (step S3).

  Next, in the analysis in step 3, the destination determination table 120 is searched according to what information is included in the SIP message (step S4).

  Next, the search result is acquired (step S5).

  Next, when the corresponding data is not found, it is determined that the received signal is an inappropriate signal, and relaying is not performed (end). When the corresponding data is found, the connection terminal determination unit 211 identifies the terminals A10 to n that can be connected by the SIP message (step S6).

  Next, the identified terminal A10 to terminal n are communicably connected to the originating external terminal C12 and terminal D13 by the connection destination determination unit 207 and the connection destination distribution unit 209 (step S7).

  Next, based on the information analyzed by the reception information analysis unit 205, transmission, reception, and transmission / reception by audio or video is performed with the terminals C12 and D13 (step S8).

  Through the steps as described above, the signal transmitted from the external terminal C12 and the terminal D13 to one number is one of the appropriate terminals A10 to n set in advance via the relay device 100 of the present invention, Alternatively, a plurality of devices can be connected to perform communication.

  In the present embodiment, description has been made on the assumption that the SIP message is determined from the combination of the media type, the media transmission / reception direction, and the route information as the destination determination table 120. As long as the terminal A10 to terminal n that are destinations can be identified by the media information, media transmission / reception direction, and route information, the configuration of the destination determination table 120 is not particularly limited.

  As described above, according to the present embodiment, the connection terminal is identified by using the incoming call information that distributes the IP telephone or IP videophone service connected to the IP network in a relay device such as a router in the home. It is possible to configure a relay method for achieving the above and a relay device for realizing the method.

  And according to this Embodiment, the content of the received call information is analyzed, the distribution of the connection to an incoming terminal is discriminated, and a plurality of terminals can be connected to one telephone number.
