Description

Telephone subscriber additional service remote control system and its operation method

The present invention relates to a supplementary service of a telephone subscriber, and in particular, a subscriber having a unique telephone number can directly control a missed information service or a call transfer service from a long distance when moving to another region. The present invention relates to a system and a method of operating the communication service of the remote control.

Most of the current public network has a network structure using register signaling (R2) for signaling between all electronic switching centers. Therefore, DTMF signals can be received by the called party while the call path is established so that the subscriber additional service can be registered. As a result, subscribers who want to receive services can register various additional services on their phones anywhere in the country, and have also been given passwords to maintain security.

In general, a function called a subscriber supplementary service or a special service is a service that allows a subscriber accommodated in an electronic switchboard to receive a special communication function in addition to a general call function, for example, a missed call to a telephone, a speed dial function, Direct calls, call transfer functions, call classification restrictions, scheduled time notifications, etc., enable the exchange to handle the appropriate services as a series of operations of the phone. Therefore, when a subscriber needs a service to a telephone station, the exchange operator registers the service as a command and the subscriber can press the telephone button, which is DTMF information, to put the service into an active mode. Since the subscriber is provided with the ability to decide whether to receive or cancel the service only within the accepted e-Exchange, the subscriber who wants to receive the service does not register the function and transfers to another area without registering the function. Service is no longer available unless you return to the location of your phone and register the function.

That is, for example, if any subscriber wants to receive the missed help service from the exchange, he / she can apply to the telephone company where his number is accepted, and if he / she is granted a function from the exchange and then press * 66 + Person Password * on his / her phone, his / her telephone will be called. Could tell subscribers that they were calling for an announcement that they were away. That is, it is possible only in the telephone with MFC symbol and in the exchange where the telephone is accommodated. In the process of processing the call, the special service is requested to the exchange system after querying the subscriber database about the special service registered by the subscriber. If you are a registered subscriber, the process of handling a phone call is different from that of a general subscriber, and you attach a dial tone after attaching a dial tone, or the number information is treated as a series of service actions. .

However, in the above-described method, if a subscriber wants to register an additional service on his / her phone, the service can be registered only in an exchange that accepts his / her phone. Therefore, the subscriber cannot move to a long distance without registering the additional service. In this case, it was not possible to provide supplementary services to other subscribers who were called by their phones.

Then, it will be described a point that was impossible in terms of the electronic switch to provide the above additional services. 1 is a block diagram of an all-electronic switchboard that performs a conventional subscriber supplementary service. Referring to FIG. 1, the fundamental reason that is impossible in the conventional exchange structure is that the DTMF detection unit 20 capable of receiving a digit signal at the called party in a state in which a communication path between stations is connected is generally a T-switch (Time-Switch) 10. In order to configure the path to the Rx channel received from the power station, it must go through the front intra-junctor of the T-switch structure, but currently it is about 1 subhighway channel. However, these channels were fixed for test or tone provision, which made it impossible for the subscriber to adopt the service itself.

In addition, as another problem of the present invention, most of domestic telephone exchange networks are R2 signaling, so receiving additional services at a long distance is difficult unless the common line signaling network is in fact important these days. . In case of common signaling method (CCS No.7), the subscriber add-on service has been developed into a structure in which the centralized station database center has been constructed and the subscriber inquiry service function has been diversified and various additional services can be easily applied. There was a problem that it was virtually impossible to remotely receive service from an analog phone.

Accordingly, an object of the present invention is to allow a general subscriber to change the called party's subscriber database information by receiving and analyzing DTMF signals transmitted from the calling party while the call path is connected between the calling party and the called party in a general public telephone network. It is to provide a method and an operating system that can be used in a variety of supplementary services in their own phone from a distance.

The present invention for achieving the above object in the subscriber subscriber service remote control system;

When the incoming call occurs at the exchange, the incoming call is analyzed, and the incoming call is connected to the other country's exchange and the call path in the remote subscriber service control foil to control the subscriber's additional service of the local exchange remotely from another area. An analog matching module is provided.

2 is a structural diagram of an analog subscriber matching module in an all-electronic exchange according to an embodiment of the present invention.

3 is a block diagram of a remote telephone call according to an embodiment of the present invention.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals have the same reference numerals as much as possible even if displayed on different drawings. In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

2 is a structural diagram of an analog subscriber matching module in an all-electronic exchange according to an embodiment of the present invention. Referring to FIG. 2, first, the subscriber matching unit 40 includes an analog subscriber interface (ASI) and a straight line concentrator (DLC) therein, and is responsible for concentrating a plurality of analog subscriber lines, and a tone (tone). Form a pass for. T-switch (time-switch) 210 is located in the front end DTMF detection unit 20, the tone generating unit 30 in the case of the outgoing so that the outgoing connection through the intra- jitter of the rear end of the T-switch 210 to allow sufficient In case of an incoming call, the receiver controls the receiving channel to control the receiving channel. The DTMF detecting unit 20 receives DTMF from a push button DTMF telephone. In addition, the tone generator 30 generates various kinds of tones (eg, dial tone, busy tone, etc.) necessary in the exchanger.

As a result, when comparing FIG. 1, which is the above-described conventional hardware configuration, and FIG. 2, which is the hardware configuration of the present invention, first, as shown in the block diagram of the electronic switching system of FIG. MFR is fixedly allocated to the transmit (Tx) channel and tones to the receive (Rx) channel in the latter stage.In the case of the calling subscriber, the tone heard by the subscriber is transmitted through the receiving channel, and the DTMF information pressed by the subscriber is connected to the transmitting channel. 2 in the structure of the DTMF detection unit 20, the tone generating unit 30 by changing the front end of the T-switch 210 in the case of the outgoing connection is sufficiently connected through the intra-jitter rear end of the T-switch 210 If possible, the incoming call can be controlled so as to control the receiving end channel. Therefore, it is possible to sufficiently overcome the shortage of intra-junction channel capacity of the conventional front-end and to receive and analyze DTMF signal transmitted from the calling party at the called party's exchange with the call path connected between calling and called parties in the public telephone network. By allowing subscriber database information to be changed, general subscribers can control various value-added services on their phones even from a distance.

Then, the remote control call processing of the present invention will be described in detail through the structure diagram of FIG. 2 and the block diagram of FIG. First, the main blocks shown in FIG. 3 are call processing processors in the electronic switchboard, and the relay call processing block 300 is a processor that handles call processing of the relay line. The received numerical information and the information of incoming and outgoing subscribers are applied and processed according to the call status, and the appropriate control command is transmitted to the subprocessor according to the result. Number translation block 310 is a processor for determining the route of the generated call is responsible for the translation of the station number and the called number. The switch control block 320 is a processor that controls the call path of the exchange. The switch control block 320 receives a request for opening and closing the call path from the subscriber control block 330 and the relay call processing block 300 to control the read command of the input T-switch. Through the S-switch and control the T-switch channel on the output side. The subscriber control block 330 includes a subscriber control processor 332 that manages subscriber call processing therein, a T-switch 336, a DTMF detector 20, and a tone generator 30. 338, and an additional service processing block 334 for processing the additional service provided to the subscriber by the exchange.

Therefore, the flow processed for the call coming from the actual foreign exchange in accordance with the present invention will be described. First, when a subscriber requests to register a remote service class with a telephone company, the operator of the electronic switch grants the corresponding function by using a command.

In step ①, if the subscriber wants to receive remote service by remotely calling his / her phone in another area, the exchange of Fig. 2 becomes the called station and the call is received by incoming call. At this time, the pass of the incoming call is determined by the number translation block 310 and forms the call path of the incoming call by the switch control block 320.

In step ②, the subscriber control processor 332 in the subscriber control block 330 processes the incoming call in the same manner as the general call processing, and analyzes the incoming call to query the remote service subscriber authorization.

When the inquiry result is a remote subscriber in step (3), the subscriber control processor 332 controls the T-switch 336 so that an internal receiving channel is used to control the channel of the DTMF generator 20 in the signal device unit 338. Occupy and switch to the mode that can receive and analyze the digit information from the sender of the power. At this time, the T-switch is controlled to connect a ringing signal to the called subscriber and to provide a ring back tone through the transmission channel to the remote station subscriber. It provides the ringing and ring back tone, drives a digit timeout, receives an MFR digit within a predetermined time, and normal call during the digit timeout. Treat it as considered.

In step ④, when the DTMF signal transmitted from the power station is received within the timeout, it is detected by the DTMF generation unit 20 in the signal device unit 338 through the reception channel of the T-switch 336 in the subscriber control block 330. do. At this time, the subscriber control processor 332 controls the T-switch to cut the ring channel and the tone channel after receiving the first digit, and sends a response signal to the power station to continue receiving the digit.

In step (5), the DTMF information normally received in step (4) is processed according to a general additional service method, and the additional service processing block 334 updates the database information related to the subscriber special service.

In conclusion, in order to remotely control the subscriber supplementary service as described above, a subscriber database is newly established by establishing a remote service class among subscriber supplementary service items and constructing a database for each subscriber. After querying, we added a function to follow the call processing flow that can be remotely controlled.

As described above, the present invention can remotely control a service on its own phone so that the user can transfer the call to his / her place in any area and receive various services to other subscribers who receive their own numbers using additional services. There is an advantage that can be controlled to do this.

In addition, due to the limitation of the existing T-switch capacity, it is possible to solve the problem of the electronic exchanger operating in the existing network, and there is an advantage that it is possible to secure a rich service channel to the subscriber by increasing the capacity.
