Abstract

A closed-circuit telephone system able to track the number of mobile telephone features that an IC card read/write device with the socket of IC card is installed in or connected to a telephone. When IC card is inserted into said read/write device, it judges the telephone number and converts it into new telephone number of this extension. When the telephone in this system is used, dialing the telephone number of the IC card can ring the telephone into which the IC card is inserted, so automatically exchanging inside telephones.

Description

The closed circuit telephone system of traceable Mobile Directory Number and application thereof

The present invention relates to a kind of closed circuit telephone system of traceable Mobile Directory Number, can use phone to pursue the callee in company or enterprises by it.The invention still further relates to the said system application corresponding.

Administrative staff wish all can converse with the callee in the shortest time behind any operating time Outgoing Call number.

In the past few years,, very big improvement and exploitation have been done for achieving the above object.Yet development along with advanced person's automatic connection switch (stored-program control exchange), usually can in the phone on the own post, import the batch processing number, when the addressee absent post, telephone rings will forward to for several times on another telephone set of previous reservation and call, but this kind method, all need make an appointment, and not change at any time on other telephone set.

In view of the foregoing, the objective of the invention is to overcome the deficiencies in the prior art and a kind of method and corresponding telephone machine of controlling phone or increasing telephone numbering be provided, make things convenient for each need make telephonic people at any time or on the system telephone machine of any enterprise, at any time set or add oneself telephone number with the simplest reserving method, make everyone receive phone in the most approaching oneself position.

The method of telephone system track phone number of the present invention, be on telephone set, to be equipped with or to be connected with the integrated circuit (IC) card reader, have IC-card on the read write line and insert mouth, the integrated circuit IC-card inserts in the above-mentioned read write line, read write line just can reset new telephone number or increase a new telephone number after confirming IC-card.

Telephone set of the present invention is made up of microprocessor, program storage, data storage, dial, clock circuit, ring detector, ring control switch, IC-card connector, double-tone multi-frequency coding and decoding circuit and ranks switch.Telephone wire connects ring detector and ring control switch through terminal and ring input circuit, and ranks switch and double-tone multi-frequency coding and decoding circuit are connected to microprocessor, and dial also is connected to microprocessor.Be connected with program storage and data storage on the microprocessor, certainly, program storage and data storage can become one with microprocessor, and microprocessor also is connected with the IC-card connector with clock circuit, by IC-card connector reading and writing IC card.

The method of telephone system track phone number of the present invention can make each telephone set in this closed circuit telephone system change or increase more a telephone number at any time, makes dialing person after dialing, and the telephone set of this number is connected and jingle bell immediately.In order to realize this using method easily, adopted the IC-card of stored information herein, be used for recording phone number.

For introducing the method and the telephone set equipment of telephone system track phone number of the present invention in detail, further illustrate below in conjunction with accompanying drawing:

Fig. 1 is the contour structures schematic diagram of telephone set of the present invention;

Fig. 2 is the telephone set of working according to method of the present invention;

Fig. 3 is a closed circuit telephone system simplified schematic diagram of the present invention;

Fig. 4 is the line module block diagram of telephone set of the present invention;

Fig. 5 is the line assumption diagram corresponding to the telephone set of Fig. 4.

Referring to Fig. 1, the figure shows the telephone set 10 that uses the inventive method, as can be seen, telephone set 10 comprises microprocessor 11, dialing keyboard 12, IC card reader/writer 13, contain one on it and hold the groove 17 that IC-card inserts, what be connected to microprocessor 11 is microphone 14, and it both can make microphone usefulness separately, also can use with loud speaker.

According to the above, those skilled in the art can recognize that phone can directly be connected with closed circuit telephone system by telephone wire 15.

Referring to Fig. 2, there is shown the telephone set of the method according to this invention work, as can be seen, IC-card read write line 13 has one and holds the groove 17 that IC-card inserts.

The user inserts IC-card (containing the telephone number card) 16 in the notches 17, and telephone set is convertible or increases a new telephone number and work.

In order to control the use of phone, unless in the IC-card read write line, insert number card, otherwise dial in behind the telephone number can't be on this special phone jingle bell.Notify from a phone call to go into to find the listener easily for making, the listener is when arriving near any one telephone set that uses in this system, the IC-card that is about to write its telephone number inserts in the IC-card socket of this telephone set, then the corresponding telephone chance immediately with this feedback information to stored-program control exchange, when the call people pushed this number, the telephone set that contains this number can be switched on and jingle bell.

Referring to Fig. 4 and Fig. 5, there is shown telephone controller of the present invention, it is by microprocessor 11, program storage 36, data storage (S-RAM) 37, dial 12, clock circuit 38, ring detector 32, ring control switch 33, IC-card connector 39, double-tone multi-frequency coding and decoding circuit 35,35 ', ranks switch 34 is formed, and telephone wire 15 is connected to ring detector 32 and ring control switch 33 through terminal and ring input circuit 31.Ranks switch 34 and double-tone multi-frequency coding and decoding circuit 35,35 ' be connected to microprocessor 11, dial 12 also is connected to microprocessor 11, is connected with program storage 36 (EPROM) and data storage 37 (S-RAM) on the microprocessor 11.Certainly, program storage 36 (EPROM) and data storage 37 (S-RAM) can become one with microprocessor, also are connected with clock circuit 38 and IC-card connector 39 on the microprocessor, by IC-card connector 39 reading and writing IC cards.

Shown in Fig. 5 each independently schemes to be interconnected to according to each port designations the line map of an integral body, wherein omitted some circuit of the prior art such as power supply etc.
