Number translation and operation method and apparatus therefor.

In a conventional exchange switch and a switch having a remote exchange structure, a translation of a station number and a called number is performed on a digit sent by any subscriber regardless of whether the remote exchange accepts subscribers of the same station number or a different station number. After the number translation is completed, in the case of the normal number, the subscriber information is obtained by referring to the subscriber number management table to determine whether the called subscriber is a subscriber of the remote switch or a host switch.

As described above, in the conventional exchange, all the digits dialed by an originating subscriber are translated, which not only takes a lot of time for translating the number, but also delays the time of occurrence of the incoming call request signal due to the number translating time. There was a problem.

Accordingly, an object of the present invention is to perform different number translation processing for a case where a remote exchange accepts subscribers of the same station number and a different station number in an exchange where a host exchanger and a remote exchange exist. To provide a number translation and operation method and apparatus therefor.

According to the present invention, there is provided a method for translating and operating a number of a switching system having a host exchanger and a remote switch structure, when a subscriber receives digit information generated for call processing; If the called party is the station number of the host exchange as a result of the translation of the station number, the step of attempting to translate the called party number: by the called party translation attempt, the called party is a subscriber accommodated in the remote exchange having the same station number as the host exchange. Searching only the corresponding route information without translating the called party's number; Performing outgoing route occupancy request processing to the corresponding remote switch using the route information retrieved in the search step; When the destination number is translated, when the called party is a subscriber who is accommodated in a remote exchange having a different station number from the host exchange or a general subscriber who is not accommodated in a remote exchange that has the same station number, Searching; It characterized in that it is carried out including the step of performing the outgoing route occupancy process using the translated call number and the retrieved route information.

In accordance with an aspect of the present invention, a device for translating and operating a number exchange system having a host exchanger and a remote exchange structure, which can determine whether a subscriber's station number, called party information and route information, and whether a recipient is a subscriber housed in a remote switchboard.

Remote switch route occupancy processing unit; And outgoing route occupancy processing using the translation result and route information of the called party when the called subscriber is a subscriber or a general subscriber who is accommodated in a remote exchange having a different station number from the host exchange. It is characterized in that it comprises an outgoing route occupancy processing unit for.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a partial block diagram of a host exchange having a number translation and operation apparatus according to the present invention, which receives digital signals generated from subscribers accommodated in a subscriber or a remote exchange (RSM) housed in a host exchange. Digit receiving unit 100 for processing, call processing means 110 for performing the call processing for the digit information output from the digit receiving unit 100, the operation maintenance unit 140 of the system, remote subscribers, including general subscribers And a subscriber number management table management unit 120 for managing the exchange subscriber number and an input / output device 130 for data input / output processing to the subscriber number management table operation unit 120.

In particular, the call processing means 110 is for outputting the incoming subscriber occupancy request signal according to the number translation result 111 provided by the number translation unit 111, the number translation unit 111 for the number translation processing for the received digits The subscriber line control unit 112 and the relay line call control unit 113 for relay line call control according to the incoming subscriber route (Root) occupancy signal output from the subscriber call control unit 112. Here, the subscriber call control unit 112 is a subscriber subscriber occupancy processing unit 1121 for receiving the occupancy process for the called subscriber according to the number translation result provided by the number translation unit 111, the recipient subscriber to the remote switch (not shown). If so, the RSM route occupancy processing unit 1123 for outputting the incoming route occupancy request signal in the remote switch to the trunk line call control unit 113, and the called subscriber who is required to occupy is accommodated in a remote subscriber having a general subscriber or another station number. The outgoing route occupancy processing unit 1122 is configured to output the outgoing route occupancy request signal to the relay line call control unit 113 in the case of the subscriber.

2 is a flowchart illustrating a process of registering and deleting a subscriber number accommodated in a remote switch in performing a number translation and operation method according to the present invention, and FIG. 3 is a flowchart illustrating a number translation process according to the present invention. .

Next, the operation of the embodiment according to the present invention will be described in detail with reference to FIGS. 1 and 2 and 3.

The process of registering and deleting the subscriber number accommodated by the remote exchange through the input / output device 130 by the operator on the host exchange is performed as shown in FIG. That is, in step 201, a signal for requesting registration or deletion of a subscriber number (RSM Directory Number) accepted by the remote switch is input through the input / output device 130. In this case, when the registration request is made, the outgoing route number which is a maritime subscriber is input. When a signal for requesting registration or deletion is input, the input / output device 130 proceeds to step 202 to search for a station number / called party management table for the remote switch subscriber in the subscriber number management table operation unit 120. In step 201, it is checked whether the subscriber number required to be registered or deleted is valid. As a result of the check, the process proceeds to step 203, if the registration / deletion process for the subscriber is registered or deleted in the station number / called party management table for the subscriber of the remote exchange, the registration and deletion process is terminated.

However, as a result of the check in step 202, the process proceeds to step 204 and the input / output device 130 outputs an error message for the operator to recognize and ends the registration and deletion operations.

Regardless of the registration and deletion of the remote switch subscriber number, the number translation process for the call generated at the host exchange is processed as shown in FIG.

That is, when the digit information is input from the subscriber housed in the host exchanger or the subscriber housed in any remote exchanger, the digit receiving unit 100 receives the digit information and transmits it to the call processing unit 110.

When the digit information is received, the call processing unit 110 requests the station number translation to the number translation unit 111 in step 301 of FIG. Accordingly, the number translation unit 111 translates the station number by referring to the subscriber number management table operation unit 120 and transmits the translated number to the destination subscriber occupancy processing unit 1121 in the subscriber call control unit 112. When the recipient subscriber occupancy processing unit 1121 is determined to be the national number translation result and the local number transmitted to the number translation unit 111, the process proceeds from step 302 to step 303 to request the translation of the called number to the number translation unit 111. Accordingly, the number translation unit 111 attempts to translate the called number by referring to the called number management table (not shown) in the subscriber number management table operation unit 120. At this time, there is information in the called party management table indicating whether the current subscriber number to be translated is the called party number of the general subscriber or the called party number of the subscriber accommodated in the remote switch. As a result of the search, if the subscriber is accommodated in the remote switch, only the route information of the called subscriber is searched and transmitted to the called subscriber occupancy processing unit 1121 without performing any translation processing for the called party.

Accordingly, the incoming subscriber occupancy processing unit 1121 proceeds from step 303 to step 304 and the system operation maintenance unit (SPM) corresponds to the state of the processor of the remote switch corresponding to the route information of the called subscriber transmitted from the number translation unit 111. 140, and if it is normal, the RSM route occupancy request signal is output through the RSM route occupancy processing unit 1123. The output outgoing route occupancy signal is transmitted to the corresponding remote switch (not shown) for the relay line call control unit 113. Accordingly, the corresponding remote switch (not shown) processes the call generated by translating the called party's called party. At this time, the signal transmitted to the remote switch (not shown) through the relay line call control unit 113 is transmitted by including the signals required for translation processing for the called party by the remote switch (not shown).

However, as a result of attempting to translate the called party number of the number translation unit 111 in step 303, if the called number is the called party number of the general subscriber housed in the host exchange, the process proceeds to step 305, and the number translation unit 111 returns to the called number. Do a translation process. At this time, the number translation unit 111 transmits the translated called party number and the corresponding route information to the incoming subscriber occupancy processing unit 1121. The incoming subscriber occupancy processing unit 1121 requests the outgoing route occupancy processing unit 1122 to perform the route occupancy process using the called number and the route information transmitted to the number translation unit 111, and the outgoing route occupancy processing unit 1122 In order to perform the corresponding outgoing route occupancy processing through the system operation maintenance unit 140 to check the normal status of the processor to which the actual incoming subscriber line belongs. If the check result is normal, the relay line call control unit 113 outputs the outgoing route occupancy request signal.

On the other hand, when the check result of step 302 is that the translated station number is not the own station number, the incoming subscriber occupancy processing unit 1121 proceeds to step 305, the station number information table (not shown) in the subscriber number management table operation unit 120; Search for the route number on the screen, output the incoming subscriber occupancy request signal, and carry out the same procedure as in the case of the general outgoing occupancy request.

As described above, according to the present invention, in the case of a subscriber having a host exchanger and a remote exchange structure having a host exchanger and a station number in the same remote exchange, the present invention allows the destination exchange to perform the host number translation at the corresponding remote exchanger. In addition to efficiently operating the number translation processing time of the exchange, the operator can easily register or delete subscriber information contained in the remote exchange managed by the host exchange.
