The present invention relates to a wide area call processing method according to a Centrix extension number assignment in an exchange system, and in particular, the same extension number for each group can be assigned when performing a Centrix function in a local exchange system. The present invention relates to a wide area call processing method by assigning a RIX extension number.

 In general, in the exchange system, the Centrix function indicates that the private exchange function is performed at the local exchange, and the private exchange usually makes calls between the subscribers using only the extension number instead of the station number. have. The function of the private exchange can be performed in the local exchange. When the extension number is used in the local exchange, the subscriber number added to the station number determined by each group is assigned to the extension number. For example, suppose that subscribers belonging to group A are 700-1000 to 700-1050, members belonging to group B are 700-1051 to 700-1100, and members belonging to group C are 700-1101 to 700-1150. As a result, the extension number of each group A is 1000 to 1050, the extension number of the group B is 1051 to 1100, and the extension number of the group C is 1101 to 1150. Therefore, even if the groups were different, they could not be assigned the subscriber extension number required by the subscriber because the same extension number was not assigned. For example, in the case of the hotel, the extension number is used for the room number. If the room number of the hotel A and the room number of the hotel B are 1001 to 1300, the extension number is required to be 1001 to 1300 at both the A and B hotels. There was a problem that this same number could not be given.

If the same A hotel is located in Seoul and Busan, respectively, when calling from a hotel in Seoul to a hotel room in Busan, call the outside call number, area code, station number and subscriber number (for example, 9-051-465-). 7000) could not be used efficiently because the extension must be pressed.

Therefore, an object of the present invention is to provide an extension number different from each group in the local exchange system, and to give the same number as the other group among the various groups to provide a broad call processing method by the Centrix extension number.

Another object of the present invention is to provide a method for wide area call processing using a Centrix extension number.

In the wide area call processing method using the Centrix extension number in the exchange system of the present invention for achieving the above object, the process of assigning the desired extension number for each group of the Centrix subscriber, and hooking the Centrix subscriber to the call Checking whether the first digit signal is an extension call or an external call when the first digit signal is received in the OFF state, receiving the extension number when the first digit is an extension call, and receiving the extension number. Is a process of detecting whether or not a wide area call, and the process of performing a wide area call process by searching the wide area census data when the extension number is a wide area number.

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.

1 is a block diagram of an all-electronic exchanger according to an embodiment of the present invention.

The subscriber control block 100 is a processor that manages the subscriber's call processing. The subscriber control block 100 receives the state and dialing information of the subscriber line and starts and terminates the call. The relay call control block 120 is a processor in charge of the call processing of the relay line and receives the information from the number translation and routing control block 110 to proceed with the call, and also receives the numeric information received from the other station and the information of the called party. Apply according to the state, and send the appropriate control command to the subprocessor according to the result. The number translation and routing control block 110 is a processor that determines the number and route of the generated call and is responsible for the translation of the station number and the called number. That is, when the subscriber control block 100 detects an outgoing signal of a specific subscriber, the number translation and routing control block 110 requests the number translation and routing process, and the number translation and routing control block 110 is called. When the number is translated and the routing is out of the outgoing foil, the occupant of the outgoing line is required by the relay line control block 120. In addition, the number translation and routing control block 110 serves to route the assigned extension number and station number according to the present invention.

2 is an exemplary diagram of randomly giving an extension number for a general subscriber number in an exchange system according to an embodiment of the present invention.

In the present invention, the extension number can be randomly assigned to the general subscriber number, and if the group is different, the same extension number can exist, and subscribers of other exchanges can also be grouped into CENTREX extension groups.

It is assumed that 600 stations and 601 stations are in their own countries, and 700 and 800 stations in other countries. At this time, as in group 1, only subscribers of other exchanges can be grouped by extension number. As in Group 2, subscribers of other exchanges and local subscribers can be grouped by extension number. Like Group 10, regardless of the station number, the number of extension numbers can be designated and grouped into the same number of extensions. As in Group 20, local station numbers can be grouped with the same extension as Group 10. That is, when the groups are different, the same extension number may exist. As in Group 100, the number of station numbers can be designated as 3 digits regardless of the station number.

In the present invention, the CENTREX subscriber can change the external call access digit used for calling a subscriber of another group or calling a subscriber of another system without going through a guide. For example, in group 1, 0 is the guide call, 9 is the external call, and 8 is the broad call number. In Group 10, 0 is a guide call, 8 is an outgoing call, and 7 is a broad call number.

3 is a flow chart of the control of the multi-subscriber call processing by the extension of the number according to the present invention, and shows the operation in the subscriber control block and the number translation block of the interchange or system of the present invention.

Referring to FIG. 3, the subscriber control block 110 checks whether a subscriber hookoff state is detected in step 301 and proceeds to step 302 when a hookoff state is detected. In step 302, if the hook-off detected line D_LINE_CATEGORY is a census line, the process proceeds to step 303 to perform general call processing if it is not a centric line. However, if the hooked-off line is a Centrix line, the flow proceeds to step 304 to allocate and connect an internal DTMF receiver and transmit a station tone to the calling subscriber. Then, in step 305, the first digit is received, and in step 306, the first digit information is obtained in R_CTRX_FDGT_INFO using the D_CTRX_GRP_NO value of the R_SUBS_DATA and the first digit as an index. That is, it checks whether the received first digit (Centrex Call Type) is an external call number, an extension number or a wide area call. For example, if the first digit is 9, the external call is called, if the 7th is the wide call, and if the first digit of the extension number is determined as the extension number. At this time, if the call is a wide area call or an extension call, the caller presses the extension number. In step 307, the caller receives the extension number and checks whether the extension number length (digit number) is received in step 308. In step 307, and continues to receive the extension number, if the extension number reception is completed, proceeds to step 309. In step 309, the received extension number is number-translated using a table in which an extension number assigned according to the present invention is stored, and in step 310, a wide area call is checked. In this case, in step 311, the global center data is searched for, and in step 312, the routing request is made to the number translation and routing control block 110. At this time, in step 313, the routing information is analyzed and outgoing occupancy request is made to the relay call control block 120 to perform wide area call processing. However, in step 310, if the call is not a wide call but a general centric call, in step 314, the incoming call information is retrieved and the call occupancy is requested in step 315. After that, the process proceeds to step 316 to perform the incoming call processing. However, if the external call is called in step 306, the next digit is received to process the external call.

As described above, the present invention can solve the problem of not accepting all the extension numbers required by the user due to the limitation of the subscriber number when assigning the extension number using the general subscriber number when implementing the private exchange function in the local exchange system. If the groups are different from each other, the same extension number can be assigned and the wide area call can be processed using the extension number.
