Abstract

The present invention relates to a register call service method of an electronic switchgear. After registering a register call service with an electronic switchgear, it is determined whether a called party is busy, and if a call is in progress, a hook / flush is performed using a terminal of the calling subscriber. Since the special code for the register call service is dialed, the calling subscriber hooks on / off the handset, and then hooks / offs the handset after a certain period of time. When the calling party registers the register call service as another called party, it registers for another called party by entering the special code as it is instead of releasing the registered party's special code. It includes a step to register the call service, so you must always go through the existing deregistration step. There is an effect that can overcome the inconvenience.

Description

Register call service method of electronic exchange

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a full electronic telephone exchange, and more particularly, to a register call service method of an all-electronic exchange that allows a call after storing a called party number in a register in a small-capacity exchange. .

In general, the register call function registers a directory number of a called party when the called party is in a call and connects the called party with a hook / off at the same time without redialing.

Conventional register call service method of the electronic switchboard is a subscriber data in the electronic switchboard using the Man Marchine Communication (hereinafter abbreviated as MMC) from the Input Output Processor (hereinafter referred to as IOP). The register call service was registered with handling (Subscriber Data Handling: hereinafter referred to as SDH).

After registering the register call service with the SDH, the calling party dials the called party to connect to the call. If the called party is busy with another called party, the calling party hears Busy Tone. .

When the tone is heard during the call, the calling subscriber may hook / flush using the terminal and hear a special dial tone according to the hook / flush from the handset.

The calling party heard the special dial tone following the hook / flush and dialed the special code * 53 # for the register call service.

After registering the special code * 53 # in the electronic switchboard as above, if the called party is busy, the calling party hooks on / turns the handset by the register call service, and after a certain time passes, Hooked off and off, so the caller was called again.

However, since the special code number is complex as * 53 #, it is difficult for a general subscriber to memorize the special code, and to store another recipient number in a register, the existing called subscriber has to be deregistered from the register. .

Here, the method of deregistering should dial special code # 53 *.

However, there is a problem in that it is difficult for the calling subscriber to remember because of the complexity and the special code to dial and repeat registration and release as described above.

The present invention has been made to solve the above problems, and its purpose is that when the calling subscriber dials to the called subscriber and does not redial, the hook / off after a certain time after hooking / turning the handset / receiver, It is to provide a register call service method of an electronic switch to be called again with the called party.

The present invention for achieving this object relates to a register call service method of an electronic switch, comprising: registering a register call service with the electronic switch; If the register call service is registered, determining whether the called party is busy; Listening to a busy tone and transmitting a special dial tone according to the hook / flush to the calling subscriber when the call is busy in the determining step; If you hear confirmation that a special code for the register call service has been entered, hook / turn on the handset / handset, and then hook / off the handset after a certain period of time, the caller will automatically reconnect to the called party without redialing to the called party. Connecting to be called; When registering the register call service as another called party other than the called party, the registered code is used as it is without immediately releasing the special code of the already registered called party. Making it possible.

Hereinafter, the objects and features of the present invention will be described in more detail with reference to the accompanying drawings so that the objects and features of the present invention can be more clearly understood.

1 is a block diagram of a register call service method of an electronic switch according to an embodiment of the present invention. The first and second subscribers 10 and 20, the IOP 30, and a line processor (hereinafter, abbreviated as LP) are shown in FIG. 40, Line Call Simulator (hereinafter referred to as LCS) 41, Main Processor (hereinafter referred to as MP) 50, Subscriber Call Control (Subscriber) Call Control (hereinafter abbreviated as SCC) 51, Number Translation (hereinafter abbreviated as NTR) 52, and Subscriber Data Handling (hereinafter abbreviated as SDH) (53) It is composed of

Terminals of the first and second subscribers 10 and 20 are connected to an electronic switchboard, and in particular, connected to the LCS 41 in the LP 40 which is a lower processor, dials to the called subscriber at the calling subscriber, and then the call is connected. A subscriber with a terminal capable of making a call.

The IOP 30 is an input / output processor and is connected to the SDH 53 in the electronic switchboard. The IOP 30 registers a register call service to the SDH 53 using the MMC.

The LP 40 internally includes the LCS 41, detects a hook off / hook on signal, detects a hook off signal among them, and converts a special code for the remote control service into the MP 50. Is a lower processor that dials to the SCC 51 in.

MP 50 internally includes SCC 51, NTR 52, SDH 53, first and second subscribers 10, 20 and relays connected to LCS 41 in LP 40; It is a higher processor that performs call processing and maintenance functions for system status management.

The SCC 51 is a subscriber call control block. The SCC 51 is connected to the LCS 41 to perform home, outgoing, and incoming call processing of the first and second subscribers 10 and 20, and generates billing information and statistical data. Collect it and send it to NTR 52.

The NTR 52 is a number translation block, which analyzes the number information transmitted from the first and second subscribers 10 and 20 to confirm the use and destination location, and retransmits it to the SCC 51.

The SDH 53 is a subscriber data handling block. The SDH 53 generates, modifies, and cancels information on the register call service transmitted from the IOP 30 and transmits the information to the SCC 51.

The register call service method of the electronic switch according to the present invention configured as described above will be described in more detail with reference to the flowchart shown in FIG.

In order to register a register call service, IOP 30 inputs a register call service to SDH 53 in a software manner using MMC.

When the register call service is registered in the SDH 53, the first subscriber 10, which is the originating subscriber, dials the second subscriber, which is the called subscriber, if the second subscriber 20 is connected to another called subscriber. When in a call (202), the first subscriber (10) hears a busy tone from the second subscriber (20).

If the call is not busy in step 202, the call is normally connected and the first subscriber 10 and the second subscriber 20 make a call.

The first subscriber 10 hears a busy tone from the second subscriber 20 and hooks / flushes it using his terminal.

The first subscriber 10 is hooked / flushed using his terminal, and listens to a special dial tone according to the hook / flush.

The first subscriber 10 hears the special dial tone according to the hook / flush and dials * 00 *, which is a special code for the register call service.

As the special code * 00 * for the register call service is dialed, the SCC 51 in the MP 50 transmits the special code * 00 * to the NTR 52 for number translation, and then the number translated register call. It is determined whether the special code for the service is registered in the database in the MP 50 (not shown).

If the registration is made in the determination step, the first subscriber 10 hears a confirmation sound that * 00 *, which is a special code for the register call service, is input.

The first subscriber 10 hears a confirmation tone that the special code * 00 * has been input, hooks on / off the handset, and then hooks / offs the handset after a predetermined time.
