Description

How to confirm registration of partial shortcut call number in exchange system

The present invention relates to a method for confirming registration of a partial reduced call number in an exchange system, and more particularly, a call number (country number + network number + area code + station number and subscriber number assigned to a specific subscriber connected to an all-electronic exchange). Registration of the partial shortened call number in the exchange system so as to confirm whether the call number of a particular subscriber station is registered as the partial shortened information in the state that it is registered as the partial shortened information in the exchange system. It is about a method.

As is well known, the TDX-10 switching system is a basic electronic switching system, such as the TDX-10 switching system, which is configured to call the called party in response to a call setup request from at least one calling party and automatically establish a call path between the subscribers. ASS (Access Switching Subsystem) for accommodating a plurality of subscriber terminals, INS (Interconnection Network Subsystem) for assigning and setting up a number translation / call in response to a call setup request from at least one subscriber terminal, It consists of a subsystem of the Central Control Subsystem (CCS) that is responsible for the maintenance and repair of the exchange system.

Specifically, the ASS includes a time switch, a signal switch, a recording guide device, an SS NO.7 signal device, a packet processing device, and the like to perform call processing functions such as subscriber and relay line matching, call origination, and incoming call. ASS is ASS-S (Subscriber) designed for analog subscriber matching, ASS-T (Trunk) for ISDN subscriber registration, ASS-S / T (Subscriber /) for relay line matching. Trunk), ASS-7 (SS NO.7) for SS NO.7 signal processing, and ASS-P (Packet) designed to be suitable for packet call processing. -10) can be employed individually or in combination.

In addition, the INS is located at the center of the corresponding exchange system to concentrate on the number translation function, route control function, and space switch connection function to perform the connection between the ASS and the connection between the ASS and the CCS.

Such INS is equipped with a data link to connect each ASS point-to-point so that communication between each ASS can only be performed via that data link (i.e. communication of information exchanged between subscribers and / or Or communication of information delivered for use within the system).

Here, the optical link between the ASS and the INS is adopted as a fiber optic link, and the TDX-10 switching system employs a TST (Time-) by a time switch located at each ASS and a space switch located at the INS. Space-Time) switch structure.

In addition, the CCS performs the overall maintenance and administration (M & A) function of the corresponding exchange system. In other words, the CCS has not only system-level maintenance, test and measurement, and control functions, but also auxiliary tape (Magnetic tape and disk) control management, various input / output door control functions with the operator, and data channel connection functions with other systems. Will be performed. Preferably, there is only a link between the CCS and the INS for control interworking.

As a TDX-10 exchange system having such a basic structure, when a call request is generated from a subscriber and / or a relay line, the ASS detects the occurrence of the call request and starts a call origination processing function. Or number translation is requested for the number information received from the relay line.

In response to the request for such a number translation, after completing the number translation, the INS performs a search and connection to establish an internal channel between the ASS accommodated by the calling party and the ASS accommodated by the called party. As a result, the calling party and the called party are initiated by the call path.

When the call between the calling party and the called party is completed, the ASS detects the completion of the call and releases the connection to the internal call, and notifies the CCS of the billing data for the call made.

On the other hand, the failure status generated from ASS or INS is notified to CCS, and the system-level maintenance functions are intensively processed by the CCS, and the operation management functions such as billing, statistics, and operator matching are intensively processed in the CCS. .

Here, for the subscriber station accommodated in the entire electronic switching system, including the TDX-10 switching system, a call number is uniquely assigned as information necessary for connection to a call. According to such a call number, the station number and subscriber number for setting the call route in a specific region are included, and the area code and exchange service applied for setting the call route with subscriber terminals accommodated in another region in connection with relay line matching are provided. The network number for identification of the network is included, and the country code for the designation of the country for connection to the call with subscribers located in other countries is included.

Therefore, in order for the calling party's terminal to be connected to the called party's terminal located in the same area to request a call, an operation of inputting the station number and the subscriber's number is required. At the time of calling, at least input operation of area code and station number and subscriber number is required, while when calling to designate a specific network, input operation of network number, area code, station number and subscriber number is required. In addition, in order to call a called party's subscriber station located in another station, input operation of country code, area code (including network number, if necessary), station number and subscriber number is required. Therefore, in order for the calling party to call the called party and make a call, cumbersome input operation is required.

In view of such a point, at present, the subscriber terminal (i.e., a telephone) is provided with a shortcut function, and when the subscriber operates a shortcut key assigned corresponding to the called party's calling number, the subscriber's calling number is automatically assigned to the called party's calling number. A dial signal is generated so that the call signal to the called party is transmitted.

As described above, when the calling party's terminal connected to the exchange system calls the called party's subscriber terminal, at least operation input of the station number and the subscriber's number is required, and a specific network is selected to select the called party in another region. In case of calling the subscriber station, additional operation input of network number and area code is required.

That is, even if the calling party terminal needs a call mainly with a plurality of called party terminals located in a specific network number and region, the calling party's network number, area code, station number, Operation is required and disadvantageous.

In addition, the shortcut key added to the subscriber terminal requires the input of at least the area code, the station number and the subscriber number of the called party's subscriber terminal and additional input of the network number, if necessary, so that it is inconvenient to use the shortcut function. In addition, such a hotkey function is only configured in the hardware of the subscriber terminal, the situation is entailed that only a limited number of hotkey assignment is possible.

In view of such circumstances, for example, for a plurality of called subscriber terminals located in the same region, a portion of the call number (e.g., area code and station number) is treated as partial shortened information, and a short code is assigned and registered in the exchange system. When making a call to the called party's terminal, the so-called 'call number part' which establishes a call path with the called party's terminal by manipulating only the short code (that is, the code corresponding to the area code and the station number) and the subscriber's number. In this case, as the amount of data stored in the exchange system in the form of partial shortened information increases, confirming whether the call number of a specific called party's terminal is registered as partial shortened information. This is necessary.

Accordingly, the present invention has been made in view of the above circumstances, and a part of a call number assigned to a called party's subscriber terminal (for example, an area code and a station number) is registered as a shortcut in the exchange system. It is an object of the present invention to provide a method for confirming registration of a partially reduced call number in an exchange system to enable registration confirmation of a call number.

In order to achieve the above object, according to a preferred example of the present invention, an ASS accommodating a plurality of subscriber stations, each of which is assigned a unique call number, and a number for the call number of the called party terminal generated through the ASS. INS for translation and call setup, and CCS with at least one storage medium in charge of maintenance and maintenance of call setup by ASS and INS. A switching system configured to establish a call path in response to an operation input of a call number of a terminal, wherein the storage medium of the CCS is mediated by an operator for registration by a partial reduction function for a part of the call number of the called party's terminal. Registering to the ASS, and the partial shortening information for the call number of the called subscriber terminal registered in the storage medium of the CCS. Downloading and storing in the database; determining whether the digit information from the calling party subscriber terminal is partial shortening information downloaded to the database, and in case of partial shortening information, a call with the called party's terminal according to the number translation result. And a step of selectively confirming whether or not the called number of the called party's subscriber station is registered as partial reduced information. This is provided.

Preferably, the partial shortening information of the called party's subscriber station includes at least an area code and a station number, and a confirmation target number for confirming whether the called number of the called party's subscriber station is registered as partial shortening information is Corresponds to the form of partial shortening information.

The method for confirming the registration of a partial shortened call number in the switching system according to the present invention having the above-described configuration includes a part of a calling number (e.g., area code and station number) assigned by a certain subscriber to a specific called party's terminal in the switching system. When the confirmation key signal and the confirmation target number are inputted from the calling subscriber terminal in the state registered by the partial reduction function, the input confirmation target number is searched in the database of the partial reduction information and executed to enable confirmation of registration.

Represents a data link connecting the CCS 60 for the purpose.

In the configuration shown in Fig. 1, according to the present invention, the subscriber terminal 10 sets a confirmation function for a call number of a specific called party's subscriber terminal in a database registered as partial reduction information in the exchange system by the following procedure. A confirmation key is assigned.

The ASS 20 may include, for example, an analog subscriber interface (ASI), a T1 (1.544 Mbps) digital trunk line interface (DTI), a CEPT (2.048 Mbps) digital relay line matcher (CEPT). Line and Trunk Access Processor (LTAP) for controlling Digital Trunk Interface (DCI), 2-wire Analog Trunk Interface (ATI), and call numbers of specific subscriber terminals assumed in the present invention are registered as partial short information. Peripheral Processor (PP) 21, which includes an LSP (Local Service Proccessor) for controlling the output of the acoustic signal for the status checking function, and most call processing functions in the corresponding ASS 20. Control for executing the partial reduction processing function of the call number assumed in the present invention and the registration confirmation function as the partial reduction information for the specific call number from the calling subscriber terminal 10 can be performed. An access switching processor (ASP) 22, data for a partial reduction processing function of a call number by the ASP 22, and data related to subscriber and / or trunk line matching are stored to access the data by the ASP 22; A database 23, a CI (Control Interworking) 24, which serves as a message communication network for a message transfer function between each of the processors including the PP 21 and the ASP 22, and which is assumed in the present invention. LDL (Local Data Link) 25 as a data link matching device for transmitting partial shortened data for a subscriber's call number or exchanging a number translation request message in response to a call setup request from the subscriber terminal 10; You will have

The INS 40 is connected to the LDL 25 of the ASS 20 via the optical cable link 30, and the data link on the communication path between the ASS 20 and the INS 40 and the communication path between the processors. CDL (Central Data Link) 41 as a matching device, CI (Control Interworking) 42, which is a kind of message processor message communication network having a message transfer function between processors, and NTP which performs number translation required by the ASS 20. And a main processor (43) including an INP (Interconnection Network Processor) for performing search and management with a call of the entire number of space switches.

The CCS 60 is a CI 61 directly connected through the CI 42 and the data link 50 of the INS 40, and an OMP (Overall) that manages a series of operations and maintenance related functions in the system. Operation and Maintenance Processor 62, a magnetic tape as an auxiliary memory device which is controlled by the OMP 62 and registers billing, statistics, maintenance, operation management information, partial shortened data of a call number assumed in the present invention, and the like. MT 63), a disk (D / D) 64, which contains a generic program and data, controlled by the OMP 62, and provides a dialogue function between an operator and a system or between an operation center and a system. It is configured to include a MMP (Man Machine Processor) (65).

In the drawing, reference numeral 70 denotes a VDU (Visual Display Unit) for dialogue between the operator and the system, and the part number of the call number is shortened at the request of the subscriber through an input device additionally configured in the VDU 70. The function is set.

Subsequently, a method for confirming registration of a partial shortened call number in the exchange system according to the present invention executed by the above configuration will be described in detail with reference to the flowchart shown in FIG.

First, a partial shortening process for the call number of the called party's terminal will be described. In step 80, the transition to the hook-off state of the calling party's terminal 10 is transferred to the LTAP included in the PP 21. When detected and delivered to the ASP 22 via the CI 24, the ASP 22 waits for input from the calling subscriber terminal 10. Then, the ASP 22 checks the grade of the subscriber station 10, and if the subscriber is allowed to call, the dial tone is transmitted by the LSP included in the PP 21 to the subscriber station 10 side. .

Subsequently, when a specific digit is input from the subscriber station 10 receiving the dial tone, the digit is interpreted by DTMF under the control of the LSP included in the PP 21 and then the ASP through the CI 24. Is applied to (22). Accordingly, the ASP 22 checks in step 82 whether the digit input from the subscriber terminal 10 is a call number of a specific called party's subscriber terminal registered in the database 23 as partial reduction information. It will determine if it is an input.

If the determination result is not a confirmation key operation for confirming the partial reduction information (i.e., NO in step 82), after setting up a call path with an operator of the VDU 70 according to a request of the subscriber of the subscriber station 10, The operator of the VDU 70 calls the MMP 65 of the CCS 60 when the operator requests registration of the call number partial reduction function and the partial number of the call number for the subscriber terminal 10 is transmitted. The number partial abbreviation function is instructed (step 84).

Here, in the partial shortening function of the called party's calling number applied to the present invention, for example, the calling party's call number of the called party's terminal that the calling party's terminal 10 needs to operate to call the called party's terminal is called. In case of area code (for example, 052), station number (for example, 550) and subscriber number (xxxx), the partial shortcut function specifies the area code '052' and the station number '550' to specify a partial shortcut key (for example, '01'). When calling the actual called party's terminal, only the partial shortcut key '01' and the subscriber number 'xxxx' need to be operated.

In response to the request of the calling party terminal 10 by the above process, when the operator of the VDU 70 generates a request for registration by the partial shortening function for a specific called party subscriber terminal, the MMP 65 Under the control of the OMP 62, the partial reduction information of the call number of the called party's subscriber terminal inputted from the input device of the VDU 70 in response to a request from the subscriber terminal 10 is, for example, under the control of the OMP 62; Recording is performed at a predetermined position of the magnetic tape MT 63 as the auxiliary storage device (step 86).

In this state, the OMP 62 transmits the call number partial shortened data to the CI 61 to be transmitted to the CI 42 side of the INS 40 via the data link 50, and the INS 40 The partial abbreviated data of the call number transmitted to the CI 42 side of the () is transmitted to the CDL 41 and is transmitted to the LDL 25 side of the ASS 20 via the optical cable link 30.

The partial abbreviated data of the call number transmitted to the LDL 25 side of the ASS 20 is transmitted to the ASP 22 via the CI 24 and downloaded to the database 23 under the control of the ASP 20. And stored (step 88).

In response to a request of the calling party terminal 10 by the above process, the call number of at least one called party subscriber terminal is stored in the exchange system corresponding to the form of a shortcut key and partial short information. When a predetermined number of digits are received from the calling party subscriber terminal 10 (step 90), the ASP 22 registers the predetermined number of digits as partial shortening information from the partial shortening information downloaded to the database 23. The authorization is determined (step 92).

If it is determined that the information is not registered as the partial shortened information (i.e., NO in step 94), the ASP 22 proceeds to execution of the normal calling process in step 96, which is the ASP 22 described above. The received digital information is applied to the CI 24 and the LDL 25 side and transmitted to the CDL 41 and the CI 42 side of the INS 40 via the data link 30, and then the MP 43 The NTP 43 corresponding to the number translation is requested.

On the basis of the result of the number translation, the NTP 43 makes an incoming request to the ASS to which the called party's terminal belongs, and if the response of the ASS to which the called party's terminal belongs is returned to the incoming request, The call path is set between the normal subscriber terminal 10 and the called party subscriber terminal.

On the other hand, if the digit information is the partial reduction information registered in the above steps 86 and 88 (i.e., NO in step 94), the ASP 22 indicates the number of the partial short information. The translated call number is used to establish a call path for a normal called party's subscriber terminal.

If the determination result in step 82 is an input of a confirmation key for confirming registration of the partial reduction information stored in the database 23 (that is, YES in step 82), the ASP 22 enters in step 100; After setting the confirmation mode for the partial reduction information, the digit input of the confirmation target number input from the subscriber station 10 is waited.

That is, the digit of the confirmation target number input from the subscriber terminal 10 is an area code (eg, '052') and a station number (eg, '052') for confirmation when the partial reduction information is composed of 'area code' and 'station number'. , '550').

Therefore, when the digit of the confirmation target number is input from the subscriber station 10, the analysis is performed according to a conventional method under the control of the LSP included in the PP 21, and the analysis result is CI. When it is applied to the ASP 22 via the medium (24), the ASP 22 searches for the confirmation target number (ie, '052' + '550') of the analysis result in the database 23 (step) 102).

As a result of the above search, if the confirmation target number exists in the database 23 ('YES' in step 104), the ASP 22 transfers the LSP of the PP 21 through the CI 24 in step 106. A tone signal (for example, a melody) or a voice guidance signal for confirming that the confirmation target number is registered is output to the subscriber terminal 10 side.

On the other hand, if the searched result number does not exist in the database 23 (i.e., 'NO' in step 104), the ASP 22 passes the CI 24 through the CI 24 in step 108. A tone signal (for example, a beep sound) or a voice guidance signal for confirming that the confirmation target number is in an unregistered state is output to the subscriber station 10 in the LSP of (21).

On the other hand, the above has been described a case where the area code and the station number are treated as partial shortening information in the call number of the called party's subscriber terminal by the partial shortening function assumed in the present invention, but the present invention is not limited to such an application example. If necessary, the country code or network number can be additionally registered as a shortened information and the registration status can be checked.

In addition, the sound signal indicating that the registration confirmation target number is registered or unregistered at the time of confirming registration as the partial shortened information may be realized in the form of visual output through, for example, a liquid crystal display device provided in the subscriber terminal 10. do.

As described above, according to the registration confirmation method of the partial shortened call number in the switching system according to the present invention, a part of the call numbers of a plurality of called party subscribers located in the same area is used as partial shortened information. When the called party's subscriber terminal can be called by the partial shortcut number in the state registered in the system, it is possible to confirm in real time whether the call number of the specific subscriber terminal is registered by the partial shortcut function. The utilization effect of the function can be further improved.
