Description

Device and method of caller information service of private exchange {Caller ID Service System In Private Branch Exchange}

The present invention relates to a service apparatus and a method for displaying caller information (caller ID, etc.) on a display terminal of an incoming service subscriber in a private exchange.

Particularly, the present invention provides a caller information service apparatus and a caller information service apparatus capable of efficiently using a resource of a trunk line receiving apparatus to perform service for caller information of more lines than the number of receiving apparatuses even with a small number of receivers. It is about a method.

Conventionally, a device for displaying caller information on a display terminal of a terminating service subscriber in a private exchange is shown in FIG. 1 by the system control unit 100, trunk line boards 1 101, ..., board n 102. In the case of the board 1 (101), the slot 1 channel unit 103 for forming a trunk line (PSTN network) and the communication path (Tx / Rx highwaw) of the system controller, and the slot 1 channel unit 103 It includes a receiving device 104 for receiving a signal through, and a system transmitter 105 for transmitting the signal received through the receiving device 104 to the system control unit 100.

In addition, in the case of the board n 102, a slot n channel unit 106 for forming a call path between a trunk line (PSTN network) and a system controller, and a receiver for receiving a signal through the slot n channel unit 106 107 and a system transmitter 108 for transmitting a signal received through the receiver 107 to the system controller 100.

Accordingly, in the trunk line board 1 101 of the slot 1, a communication path is made with the trunk line side through the slot 1 channel unit 103 interfaced with the PSTN network, and a voice signal is transmitted to the system controller 100 through the Tx / Rx highway. The voice signal is transmitted to the extension subscriber to form the entire call path.

At this time, in order to perform a service for displaying the caller information on the display terminal of the called subscriber, the caller information is received at the receiving device 104 and transmitted to the system control unit 100 through the system transmission unit 105, the system control unit In step 100, the caller information is sent to the display terminal of the called party so that the caller information is displayed on the subscriber terminal.

That is, before the channel is opened, the caller information coming from the CO line is detected by the slot channel unit and notified to the system control unit, and the system control unit informs the extension subscriber so that the caller information is displayed on the terminal capable of displaying the caller information. From this, the subscriber of the called party can view the caller's information.

The same applies to the board 103 of the slot n.

That is, the conventional technique uses one receiver 104 for each line of a trunk line board, and a separate receiver 107 is also used for the board 106 of an adjacent slot.

Therefore, if a 16-line trunk line board is inserted into two slots, a total of 32 receivers are required.

Since there is one receiver for each line like this, if the actual amount of talk time is 50%, for example, the receiver used will correspond to 50% and the remaining 50% of the receiver will be in an unused state. In addition to inefficient system operation, the receiving device of a specific slot was not able to be efficiently used in terms of resource utilization because the receiving device can receive only the corresponding line of the corresponding slot.

That is, since the trunk line board 1 101 of the slot 1 can be received only by its own receiver 104 and cannot be received by the receiver device 107 of the trunk line board n 102 of the adjacent slot n, it is redundant. It is a structure that cannot utilize resources (receiving devices of adjacent unused slots).

According to the present invention, in performing a service for displaying caller information on a display terminal of a terminating service subscriber in a private exchange, a caller of many lines can be received even with fewer receivers by efficiently using the resources of the trunk line receiver. Provided are a caller information service apparatus and a method of a private exchange that can be in charge of an information display service.

In the present invention, in performing a service for displaying caller information on a display terminal of a terminating service subscriber in a private exchange, the receiving device is modularized / optional, and when the caller information comes from the CO line, the receiver is not currently used. The present invention provides a device and a method for calling party information service of a private exchange, by searching for (idle receiving device) and connecting and receiving the caller information to a receiving device that is not currently used to perform a more efficient caller information display service.

In the present invention, in performing a service for displaying caller information on a display terminal of a terminating service subscriber in a private exchange, the receiving device is modularized / optional, and when the caller information comes from the CO line, the receiver is not currently used. Caller of a private exchange to expand the search to the trunk line board of the adjacent slot and to perform the more efficient caller information display service by connecting the caller information to an unused receiving device including the adjacent slot. An information service apparatus and method are provided.

Hereinafter, a caller information service apparatus and a method of a private exchange of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 2 is a block diagram showing an embodiment of a caller information service apparatus of a private exchange of the present invention, and Fig. 3 is a flowchart for explaining the caller information service method of the private exchange of the present invention.

Referring to Fig. 2, the caller information service apparatus of the present invention includes a main controller 201 including a switching unit 201a, a trunk line (PSTN network), and the like to establish a call path and control caller information processing. A trunk line board 202a and 202b for performing voice call processing and caller information processing between the main controller 201 are included.

The trunk line boards of the slot form a voice call path as an interface between the trunk line and the main control device 201, and the slot channel unit 203 for detecting the caller information and the caller information detected by the slot channel unit are present. A receiver unit 205 including a PCM adjuster 204 for assigning to a usable receiver, at least one receiver 205a selected by the PCM adjuster 204, and the receiver 205a And a storage unit 206 for storing the caller information received by the processor, and a processor unit 207 for transmitting the message of the sender information stored in the storage unit 206 to the main controller 200.

In FIG. 2, reference numeral 208 denotes a system bus, Tx represents a transmission highway, and Rx represents a reception highway.

Meanwhile, in FIG. 2, the number of receivers 205a may be set to a number corresponding to 50% of call traffic.

In general, in view of the operation mode of the private switching network, the reception device corresponding to about 50% of the call traffic is different because the frequency of use and the number of traffic are different depending on the time of day or the characteristics of the subscriber, rather than using all of the available lines at the same time. This is because it may be provided.

That is, in the present invention, for example, it means that there are about 8 receivers instead of 16 receivers on a trunk line board having 16 lines, so that several lines can be serviced using about 8 receivers. This is because it is a feature and advantage of the present invention.

In addition, when traffic exceeds the trunk line board of the current slot, the receiver in the trunk line board of the adjacent slot can be used to substantially eliminate traffic.

Referring to Figures 2 and 3 the caller information service operation according to the present invention will be described.

The communication channel is established with the main line (PSTN network) side by using the slot channel unit 203 as an interface, and the voice signal is transmitted to the main controller 201 through the transmission and reception highways (Tx, Rx). The entire call path is formed by connecting to the extension subscriber through the switching unit 201a.

At this time, the caller information input from the CO line is detected by the slot channel unit 203 before the call path is opened and notified to the main controller 201, and the PCM adjusting unit 204, the receiving unit 205, and the storage unit 206. By sending the sender information (message) processed through the processor unit 207 and the system bus 203 from the main control unit 201 to the terminal of the station subscriber, caller information is displayed on the station subscriber terminal.

This process is described in more detail.

First, when a ring for receiving a specific channel from the slot channel unit 203 is reached (step 301), the PCM adjusting unit 204 is currently used among the receiving devices 205a in the receiving unit 205. Search for the presence or absence of a possible receiver (i.e., a receiver not in use) (step 302).

If there is a receiver (idle receiver) available as a result of the search, the PCM coordinator 204 connects the corresponding time slot of the transmission highway Tx to the receiver 205a which is not currently used, and then connects the trunk line (PSTN network). Receive caller information from the mobile station (step 303).

In this way, the caller information received by the receiving device 205a is stored in the storage unit 206 (step 304).

The processor unit 207 reads the sender information stored in the storage unit 206 and transmits it to the main controller 201 via the system bus 208 (step 305).

The main control device 201 messages and transmits caller information entered through the system bus 208 to an extension subscriber board (not shown) (step 306).

The extension subscriber board transmits this caller information (messaged caller information) to the corresponding subscriber station so that the caller information is displayed on the subscriber station (step 307).

On the other hand, if all of the receiving devices 205a in the trunk line board 202a of the slot 1 are in use in the search (confirmation) step of the available receiving device 205a, the receiving device (not currently being used as the main controller 201 ( Message 205a) (step 308).

That is, the processor unit 207 identifies the receiver that is not currently used, and then adjusts the PCM adjusting unit 204 in the new call process to transmit / receive the highway Tx of the slot 1 channel unit 203. / Rx) and sender information processing to unused receiver 205a, if the traffic on the call exceeds the number of available receivers, then message is sent to main controller 201. It is made by sending it.

When the main control device 201 receives the message corresponding to the traffic over traffic through the system bus 208, the main control device 201 switches the switching unit 201a (step 309).

Accordingly, the caller information is processed by the trunk line board 202b of the adjacent slot via the switching unit 201a.

As described above, the trunk line board 202b of the adjacent slot proceeds with the control procedure from the search (verification) step 310 of the receiver which can be used, thereby receiving, storing, messaging, transmitting and displaying caller information. You lose.

This series of steps can be repeated up to n slots (step 311).

Therefore, it is not necessary to have the number of receivers in one trunk line board, and the caller can use the available receivers in the trunk line board of adjacent slots when it is unable to process in the magnetic board. Information service can be performed.

Therefore, according to the apparatus and method of the caller information service of the private exchange of the present invention, the use efficiency of the receiver can be maximized, and in particular, since the receiver of the corresponding slot can be variably adjusted, the trunk line board as well as the adjacent slots can be used. Caller information service resources can be utilized for boards with other types of interfaces.

In addition, in the case where the receiver unit 205 is modularized / optioned as a separate board in FIG. 2, the receiver does not need to occupy a slot of the system separately, and allows the maximum line capacity of the system to be sufficiently used. In addition, in case of high traffic at the exchange, the service capacity can be expanded by installing a separate receiver as an option.

According to the apparatus and method of the caller information service of the private exchange of the present invention, in processing caller information, the presently available reception is provided with an appropriate number of receivers considering traffic by call without having one receiver for each channel. Since the device can be searched and confirmed in advance and caller information can be assigned to a receiving device that is not in use, the resource can be efficiently operated.

In addition, since the number of receivers can be reduced, and the caller information receiver can be used by extending to adjacent slots, the board configuration can be simplified and the cost can be reduced, and the boards with other types of interfaces can be used as resources. This is possible, and because it does not use a dedicated board dedicated to the receiver device, it is possible to eliminate the problem of assigning a separate slot to increase the system usage efficiency.
