Abstract

PURPOSE:To receive an incoming call by selecting a terminal with the highest likelihood by calling to select the information of an intermediate destination with the highest communication frequency as the communication opponent of an outgoing person identification number(outgoing ID) detected from a communication history, and re-calling the intermediate destination with the next higher communication frequency when no response is obtained. CONSTITUTION:An incoming call on which the outgoing ID of an outgoing person is attached is transmitted to the private branch exchange 4 of an incoming destination via a communication network 2. An intermediate function circuit 5 in an incoming intermediate device 3 which selects an incoming destination retrieves the communication history DB 6, and retrieves an intermediate destination list storing a group of intermediate destination terminal candidate having the history of communication with the outgoing ID in the past, and selects Mr. Y with the highest precedence out of the group with the highest speech frequency, and after recognizing his presence, calls and connects the intermediate destination terminal 8 to an outgoing terminal 1. In such a way, it is possible to select and make a call arrive at an opponent or a terminal with the highest likelihood.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a private branch exchange that allows calls to be received by a desired party or terminal without specifying the extension number of a PBX or CBS, the terminal configuration, etc. The present invention relates to a communication device.

[Conventional technology]

In order to automatically dial a terminal belonging to a PBX or CBS, a redial method using a second dial tone has conventionally been adopted. Even in small-scale private branch exchanges such as PBXs, it is necessary to have a dedicated person to handle the connection.

On the other hand, in public communication networks, communication service interfaces are becoming increasingly sophisticated and digital, and in April 1988, I-interfaces for transmitting caller IDs began to be provided to the general public. Therefore, in the future there will be a need for services that make effective use of the interface function, and expectations are high for extension intermediary systems using caller IDs, which have not been possible with existing analog networks such as telephone networks.

[Problem to be solved by the invention]

In the conventional method for automatically dialing a terminal belonging to a private branch exchange such as a PBX or CBS, the caller must be aware in advance that the other party is connected to a private branch exchange, and must know the extension terminal number before making a call. . In addition, the number of cases in which the other party is using a device other than a telephone, such as a fax terminal, is increasing, and the caller is conscious of such information such as extension numbers when making a call, and it is difficult for a person to intervene in the incoming call. , it was necessary to transfer it again to the appropriate terminal.

Therefore, if this information is not known in advance, a situation may occur in which connection to the intended party or terminal cannot be made, and for this reason, even small-scale PBXs must have a dedicated operator. In order to prevent this, there is a need for a means for allowing a caller to receive a call to a desired party or terminal without being aware of the extension number, terminal configuration, etc.

[Means to solve the problem]

When there is a call from a terminal that accommodates a call, a private branch exchange connected to a communication network that sends a signal with a caller ID that identifies the caller to the destination, sends a signal to the caller ID that identifies the caller. , means for forming a communication history DB that sequentially adds, updates, and records communication history information of the terminal of the private branch exchange that is the communication partner of the caller ID, and a caller I that receives calls from the communication network.
means for detecting D and connecting to an incoming call handling device, and information on a destination terminal with the highest communication frequency or a destination terminal with the highest connection priority as a communication partner of the caller ID detected from the communication history DB. means for calling the destination terminal indicated by the information and connecting to the destination terminal; and means for re-calling the next destination terminal having a higher connection priority when there is no response from the destination terminal after calling. and means for activating the device.

Furthermore, connection priority candidates are selected from the communication frequency information recorded in the communication history DB, communication date and time information, media information used for communication, and destination terminal information, and further information on the organizational structure, terminal installation location conditions, and means for determining the connection priority order using the terminal type.

Reference numeral 1 denotes a calling terminal, 2 a communication network, 3 an incoming call handling device, 4 a private branch exchange, 5 a handling function circuit, 6 a communication history database, 7 a schedule management table, and 8 a relay destination terminal.

In order to communicate with the destination terminal 8, the originating terminal 1 transmits the number nnnn of the office or the like. Caller's call to number nnnn
An incoming call with D (=4202) added is a communication f! It is delivered to the destination private branch exchange 4 with number nnnn, such as a business office, via i2. The intermediary function circuit 5 of the incoming call intermediary bag W3 that selects the incoming call destination searches the communication history DB 6 and selects the incoming call destination.
0 (=4202) is searched in the service destination list that stores the set of destination terminal candidates that have communicated with 0 (=4202), and further searches the schedule management table 7 that records and maintains the schedules of the destination terminal candidates as necessary. Then, from the group with the highest call frequency, 7 people with high priority are selected, and knowing that they are currently present, calls the agency destination terminal 8 and connects to the calling terminal 1.

Use the source material.

(3) Function of each circuit.

The demultiplexing circuit 11 of the private branch exchange 4 demultiplexes channels when a basic type I interface (2B+D) is assumed as a subscriber interface. The caller ID/media acquisition circuit 12 corresponds to caller ID detection means and communication media detection means, and reads these pieces of information from a predetermined field of the D channel signal. The destination candidate search circuit 13, which corresponds to connection priority detection means, uses the originating ID obtained from the originating ID/media acquisition circuit 12, communication media, and internal clock 1.
According to the key conditions of the date and time information obtained from step 7, the communication history DB 6 is searched for a candidate list of agents that meets the conditions.

The agent determination circuit 14 searches the communication history DB 6 (
With reference to past intermediary cases stored in FIG. 3), the connection priorities for these intermediary destinations are calculated. If the agency candidates cannot be narrowed down sufficiently, the agency candidate search circuit 13 orders the agency candidates according to the communication partner, communication time, or medium, as necessary. Inference is made using knowledge rules that express the organizational structure, terminal equipment location conditions, terminal type, and past agency cases described in advance, and the agency candidate with the highest connection priority for each candidate is determined. Agency method determination circuit 15
The communication control circuit 16 refers to the transfer destination order determined by the transfer destination determination circuit 14 as well as the schedule management table 7 (FIG. 4), and determines the transfer method according to the connection priority order. control terminal and D channel signals;
Execute calls, connections, communication termination, etc. The man-machine inaction control circuit (referred to as M M r *I control circuit) 23 mediates the exchange of information between the communication control circuit 16 and the destination terminal 8 , and uses the call information from the communication control circuit 16 to communicate with the destination terminal 8 . calls and displays the operation menu for
Necessary communication control is activated in the communication control circuit 16 based on the operation performed by the destination terminal 8, and the originating terminal 1 and the destination terminal 8 are connected. The update control circuit 18 monitors the operation sequence of the destination terminal 8 from the MMI control circuit 23, and detects an explicit affirmative operation of the destination terminal 8 (MMI control circuit 2
3 (e.g., inputting "yes" in response to "Is the current caller correct?") and implicit affirmative actions (e.g., responding to an incoming call within 1 second) The communication history update circuit 19 is controlled to update the communication history only when the conditions are met. The history update circuit 19 updates the contents of the communication history DB 6 according to the instructions from the update control circuit 18 using methods such as linear prediction based on the agency and the agency method output by the agency method determining circuit 15. The calling circuit 21 calls the destination terminal 8, and the presence sensor 22 identifies whether the destination terminal 8 is present or not.

(4) Operation of the present invention.

When a call arrives at the incoming call handling device 3, the D channel signal of the basic type I interface (2B+D) of the subscriber interface is demultiplexed by the demultiplexing circuit 11 of the private branch exchange 4, and its output is sent to the forwarding connection priority circuit. Episode 5 I
The ID is input to the D/media acquisition circuit 12, and the originator ID is acquired by the originator ID/media acquisition circuit 12. A destination candidate search circuit 13 connected to the originating ID/media acquisition circuit 12 searches the contents of the communication history DB 6 using the originating ID, and passes the result to the destination determining circuit 14. Delivery destination determination circuit 14
is the connection priority, that is, the likelihood, of the agency candidate in the communication history DB.
The calculation is made with reference to the communication history information of Mr. 6, and it is recognized that Mr. 7 is the most likely candidate for the agency.

If there are multiple destination candidates and the difference in connection priority between them is small and the destination cannot be determined meaningfully,
The destination candidate search circuit 13 searches the communication history circuit 6 using the arrival time (time zone) or the communication history DB requested medium as key conditions, calculates the time precedence from each candidate, and finds the most likely one cross-sectionally. It executes processing such as selecting a successful agency from past similar agency cases, and notifies the agency method determining circuit 15 of the agency with a high connection priority.

The agency method determining circuit 15 determines the priority of the agency, the status and schedule of the agency (receiver) based on information from the schedule management table 7 or the presence sensor 22, or, if necessary, the information stored in the communication history DB 6. Refer to past intermediary cases, etc., and infer the intermediary method with the highest connection priority.

The agency and agency method determined in this way are the communication control circuit 1
At the same time, the MMI control circuit 23 calls the destination terminal 8, which is the destination, and accepts the operation of the destination terminal 8.

If the destination terminal 8 responds positively to the incoming call, etc., the update control circuit 18 determines that the destination and the transfer method were appropriate, and the history update circuit 1
9, the contents of the communication history DB 6 are additionally updated to include the agency and the agency method. If the transferee terminal 8 does not respond to the incoming call for a certain period of time or transfers the call to another receiver, etc., the update control circuit 1
8, it is determined that there is an incomplete part in the agency or agency method, and the agency decision circuit 14 or agency method decision circuit 15 is activated to re-infer the agency or agency method, and the next priority is determined. The agency and agency method will be determined. The contents of the communication history DB 6 will gradually change to reflect the actual situation due to the update process of the history update circuit 190 as the number of transactions increases.As the number of transactions increases, the contents of the communication history DB 6 will gradually change to reflect the actual situation. We can expect scales to increase the probability that .

By operating in this manner, it is possible to select the most likely party or terminal to receive a call.

The communication history DB 6 records the communication partner, communication frequency information, communication date and time information, media information used for communication, destination terminal information, organizational structure, terminal installation position conditions, and terminal type.

〔Effect of the invention〕

As explained above, the communication history information held on the receiving side is searched using the information sent from the network side at the time of receiving the call, such as the caller ID, communication time, and the media used, and the most likely recipient or It is possible to select a terminal to receive a call, and furthermore, the organizational structure and terminal arrangement configuration at the installation location of this device are determined for each destination candidate obtained from the above information sent from the network side at the time of receiving a call. By using information to verify and narrow down candidates and increase the accuracy of transfers, ■ For the caller, the caller does not have to answer the incoming call first before proceeding with the transfer. The time required to connect to the terminal is the same as for a standalone terminal. That is, it is convenient because dialing only needs to be done once, and it is possible to make a call using the same procedure as for a single terminal without being aware of whether the other party is a single terminal or a PBX/CBS.

In addition, even if you do not explicitly specify the party or terminal you want to receive a call under this device, or even if you do not know that information in advance, there is a high probability that the call will arrive at a reasonable destination, so it is difficult to access the calling side. Less knowledge is required.

■ For the called party, there is no need to register the terminal configuration under this device, the sub-number, etc. to the calling side or the network side in advance, so the terminal configuration under this device can be made more flexible.
It also helps ensure privacy.

In addition, in order for the caller to know the person or device they want to receive the call from,
- Since you can increase the probability that the call will arrive at the desired destination without having to manually handle incoming calls and explicitly specify the destination or terminal, there is no need to have a dedicated handler, contributing to streamlining. do.
