The present invention relates to a service method of an exchange system, and more particularly, to a service method for a caller identification (CID) trunk line.

Currently, some of the local exchanges send the calling party number to the called party through the trunk line to check the calling party number. Accordingly, among the trunk lines that are connected to the exchange system such as the key phone system and the premises exchange system, there are trunk lines that send caller IDs and trunk lines that do not send. Typically, a CO line that sends a calling party number is called a calling party number CO line and a CO line that does not send a calling party number is called a general CO line.

When a caller's number is ringed, a certain time must be waited to receive the caller's number. In the case of a general trunk line, a ring should be provided immediately to the station without waiting.

However, the conventional switching system did not have a function of determining whether the incoming trunk line is a caller ID trunk line or a general trunk line. Accordingly, there was a problem in that differentiated services could not be provided depending on the type of CO line.

Accordingly, an object of the present invention is to provide a caller number trunk line service method that can provide a differentiated service according to the type of trunk line by specifying the caller number trunk line.

In order to achieve the above object, the present invention distinguishes and specifies the calling party number of the trunk line, and checks whether the calling party number is assigned to the corresponding trunk line when receiving the trunk line, and receives the calling party number if the calling party number is the trunk line. It is characterized by providing the same service to the station as a general CO line.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description and the annexed drawings, many specific details are set forth in order to provide a more thorough understanding of the present invention, such as specific processing flows, keystrokes, buffer configurations, and the like. It will be apparent to those skilled in the art that the present invention may be practiced without these specific details. And a detailed description of known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

In addition, in the embodiment of the present invention will be described with an example applied to the key phone system.

1 shows a system configuration diagram of an exchange system to which the present invention is applied, taking an example of a general key phone system. The key phone system 10 is connected to a plurality of trunk lines connected to the national exchange 20 and a plurality of stations connected to extension subscribers of a key phone or a general telephone, respectively, to perform exchange services for trunk lines and stations. The key phone telephone 30 is connected to the key phone system 10 through the corresponding extension, performs a call service through the key phone system 10, and performs various data communication including the key phone system 10 and the MMC. The key phone telephone 30 is generally a handset 40 for voice transmission and reception, a display device 50 such as an LCD panel for displaying various operating states, a large number for MMC (Man Machine Communication) and performing various functions. And a function keypad 60 having function keys, and a numeric keypad 70 for dialing and inputting numbers. In FIG. 1, among the function keys of the function keypad 60, the keys used in the present invention include a program key used to perform a program mode by the MMC, a volume increase key and a volume decrease to increase or decrease the volume, respectively. Key and a shift key for moving a cursor on the display device 50 are shown. In addition, since the detailed configuration of the key phone system 10 and the key phone telephone 30 is well known, illustration and description thereof will be omitted.

In order to provide differentiated services according to caller number trunk lines or general trunk lines in keyphone system 10 as shown in FIG. 1, caller number trunk lines should be designated for trunk lines connected to keyphone system 10. To this end, a trunk line designation buffer is configured in the memory in the key phone system 10 as shown in FIG. The designated trunk buffer is allocated one byte for each trunk line. The designated trunk line is set to 1 when the trunk line is the calling party number.

An example of designating a caller number trunk line according to the trunk line for the trunk lines connected to the key phone system 10 is illustrated in the flowchart of FIG. The flowchart of FIG. 2 is performed by data communication with the key phone telephone 30 in the main control unit which is usually provided in the key phone system 10. If a user such as a system operator or an extension subscriber wants to designate a caller ID trunk line, input a program key of the key phone telephone 30. Then, the key phone system 10 recognizes this at step 200 and starts to perform the program mode.

When the user inputs the caller ID trunk line designation MMC number in the above state, the key phone system 10 determines whether the current trunk line of the trunk line designation buffer, that is, caller number trunk line designation, is performed in steps 202 and 204. Check and display on the display device (50). At this time, an example of the display state of the display device 50 is shown in FIG. In FIG. 5, '[710]', '[702]' indicates a corresponding trunk line number, 'CID TRUNK' indicates a caller ID trunk line, 'NORMAL' indicates a general trunk line, and '_' indicates a cursor.

Then, the user selects the CO line to be designated, and the key phone system 10 performs steps 206 to 214 according to the user's key input to display the state of the CO line designated by the user and moves the cursor when the moving key is input. Move the calling party number to the designated line. At this time, if the CO line number is inputted, the state of the CO line is displayed as shown in FIG. 5 (b), and when the movement key is input to change whether the caller number is CO line, the cursor is moved as shown in FIG. 5 (c). Move to. When the program key is input, the operation is terminated as it is.

In the state shown in FIG. 5 (c), the user designates the caller number of the corresponding trunk line using the volume up key or the volume down key. When the volume up key or the volume down key is input, the keyron system 10 switches the display state of the caller number trunk line and the general trunk line at each key input in steps 216 and 220. For example, if the volume increasing key is input in the state shown in FIG. 5 (c), the display state is changed as shown in FIG. At this time, if caller ID trunk line is changed by input of volume up key or volume down key, contents of trunk line designation buffer are set to 1 or cleared to 0 accordingly. In addition, if a program key is input, the process ends in step 224, and if a movement key is input, the process returns to step 206 in step 226.

In the state as described above, the caller system 10 performs the service according to the flowchart of FIG. 3 when the CO line is received. The flowchart of FIG. 3 is performed by data communication with the key phone telephone 30 in a typical main control section of the key phone system 10. As shown in FIG. When the CO line is received, the key phone system 10 recognizes this at step 300 and checks the contents of the CO line designated buffer for the corresponding CO line at step 302 to confirm whether the caller number is CO line. If the incoming CO line is a calling party number CO line, in step 304 and 306, after receiving the caller number from the corresponding CO line, the CO line routine is performed in step 308 to provide a ring to the corresponding station. On the other hand, if the incoming CO line is a general CO line, the general CO line incoming routine of step 308 is immediately performed to provide a ring to the corresponding station.

As described above, the present invention has the advantage of improving the service of the exchange system by designating the caller ID trunk line and providing differentiated services according to the trunk line.

In the above description of the present invention, specific embodiments have been described, but various modifications can be made without departing from the scope of the present invention. In particular, various keys for carrying out the present invention may be substituted with other keys provided in a key phone. In addition, although the embodiment of the present invention illustrates the application to the key phone system, it may be applied to a simple exchange system such as an on-premises exchange system without any special modification. Therefore, the scope of the invention should not be defined by the described embodiments, but should be defined by the equivalents of the claims and the claims.
