JPH03123161A - Exchange with subscriber's number retrieving function - Google Patents

Abstract

PURPOSE:To constitute the exchange so that the exchange has attribute data related to a subscriber, and when a calling party designates this attribute, the subscriber corresponding thereto is detected and connected. CONSTITUTION:Based on an attribute of a called subscriber which a calling subscriber sends out together with a calling request, a subscriber retrieving part 10 decides whether a subscriber corresponding to this attribute is contained in the own exchange 20 or not, from the storage contents of attribute data 12. When the subscriber is not contained, it is disconnected, and when it is contained, by retrieving a data base 13 in which correspondence of this attribute and the subscriber registered in advance is described, the called subscriber is identified, and called by a calling request means. In the case the called subscriber does not answer, another subscriber for satisfying the previous retrieval condition is selected again, and the calling request means is operated again. In such a way, for instance, at the time of calling to a hospital, in the case any surgical hospital will suffice, and it is unnecessary to designate especially a called destination, necessity for retrieving personally telephone numbers allocated to one-to-one can be eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an exchange, and particularly to an exchange with a subscriber search function.

[Conventional technology]

Conventionally, an exchange has performed a connection operation between subscribers by designating a number assigned to each subscriber on a one-to-one basis.

[Problem to be solved by the invention]

Conventionally, when a subscriber makes a call request, for example, if a call is made to a hospital, any hospital with a surgical department can be used, and even when there is no need to specify the destination, calls are assigned on a one-to-one basis. There is a problem in that it is necessary to search for the telephone number by oneself, and if the called subscriber is absent, it is necessary to search for the telephone number again in the same way.

[Means to solve the problem]

The switching equipment with a subscriber number search function of the present invention has a first function that stores only the types of data that actually exist among the attribute data such as region, occupation, age, etc. to which the subscriber belongs in the switching equipment.
a second storage means for storing individual attribute data of the subscriber; a designation means for a calling subscriber to designate an attribute possessed by a called subscriber; and an attribute designated by the designation means. a selection means for searching for subscribers corresponding to this attribute according to the search condition and selecting one of the subscribers corresponding to the search condition; and a call request means for requesting the selected subscriber to make a call, The selection means determines whether or not the subscriber corresponding to the attribute is accommodated in the own exchange based on the attribute of the called subscriber sent by the calling subscriber together with the call request. Judging from the stored contents of the storage means, if there is no such attribute, the call is disconnected, and if there is, the second storage means is searched in which the correspondence between this attribute and the previously registered subscriber is recorded, and the called subscriber is connected to the called subscriber. and causes the call to be received by the call requesting means, and if the called subscriber does not respond, another subscriber that satisfies the previous search condition is selected again, and the call requesting means is operated again. This is a configuration that allows

〔Example〕

The present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of an exchange system according to an embodiment of the present invention.

10 is a subscriber search section of the present invention, 20 is an exchange main body that performs normal switching operations, and 30 is an inter-unit communication section. 11
12 is the central processing unit of the subscriber search unit 10, and 12 is attribute data in which the attributes of data held by this exchange system are written. It is used to search for the presence or absence of a person. A database 13 holds attributes and identification numbers of each subscriber. Reference numeral 14 denotes an input/output unit to which a workstation or the like for updating and modifying the database 13 is connected.

FIG. 2 is a format diagram showing the logical structure of this database.

The database uses the subscriber ID as an index and is composed of invalidity display, occupation and other attributes.

Next, the operation of the exchange system will be explained with reference to the drawings.

The exchange main body 20 shown in FIG. 1 receives attribute designation as called party information from a subscriber, and passes the attribute information to the central processing unit 11 of the search unit via the communication unit 30.

The attribute data 12 holds a list of attribute information that can be handled by the exchange, and checks whether the attribute given from the exchange main body 20 is defined within the exchange main body 20. Here, if the attribute is undefined,
The answering device in the exchange main body 20 is activated and the caller is notified of this. If the attribute is defined, the central processing unit 11 searches the database 13 and identifies the called party.

The database 13 has a search valid/invalid display area, and only subscribers with a valid display are searched. 1'' is written in the invalid display area for the database corresponding to the identified called party.

Thereafter, the logical number (telephone number) possessed by the called party is notified to the exchange main body 20, and the exchange main body 20 begins normal call origination operation. Here, if there is a response from the called party, normal call and disconnect operations are performed, but if the called party is absent or the call is not received, this fact is reported to the subscriber search unit 10. do. After the subscriber search section 10 searches again and specifies the subscriber, it reports this to the exchange main body 20 and performs normal operations. If no call is received, after repeating these steps several times, the exchange main body 20 returns a busy message to the caller.

〔Effect of the invention〕

As explained above, when the exchange has attribute data regarding the subscriber and the calling party specifies this attribute,
It becomes possible to find and connect to a corresponding subscriber. In addition, if the initial loud sound does not allow the call to be received,
It is possible to connect to another subscriber with the same attributes without the caller being aware of it.

Claims (1)

[Claims] A first storage means for storing only types of attribute data such as area, occupation, age, etc. to which a subscriber belongs to the exchange, for which data actually exists; and a first storage means for storing individual attribute data of the subscriber. a second storage means for specifying an attribute of the called subscriber by the calling subscriber; and a specifying means for the calling subscriber to specify an attribute of the called subscriber; a selection means for selecting one of the selected subscribers; and a call request means for making a call request to the selected subscriber; Based on the attribute of the called subscriber to be sent, determining whether the subscriber corresponding to this attribute is accommodated in the local exchange from the stored contents of the first storage means;
If not, the call is disconnected, and if there is, the called subscriber is identified by searching the second storage means in which the correspondence between this attribute and the previously registered subscriber is recorded, and the called request means When the called subscriber does not respond, another subscriber that satisfies the previous search condition is selected again, and the call requesting means is operated again. Functional exchange.
