Description

Billing confirmation method in subscriber terminal {METHOD OF CONFIRMING CHARGE FEE IN SUBSCRIBED TERMINAL SET}

The present invention relates to a charging confirmation method in a subscriber terminal, and more particularly, in response to a request from a specific subscriber terminal registered with a charge confirmation service in an electronic switching system, the call charging status of the subscriber terminal on the subscriber terminal. The present invention relates to a charging confirmation method in a subscriber terminal for displaying and confirming.

In general, an all-electronic switching system that calls a called party in response to a request from a calling party's terminal and automatically establishes a call path between the calling party and the called party's terminal is generally appropriate. ASS (Access Switching Subsystem) to which a number of subscriber terminals are connected, INS (Interconnection Network Subsystem) in charge of allocating / setting up a call in response to a call connection request generated through the ASS, and a corresponding exchange system It is equipped with the Central Control Subsystem (CCS) for the maintenance and repair of management and the management of billing information.

Specifically, the ASS is equipped with 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) for analog subscriber matching, ASS-T (Trunk) for ISDN subscriber registration and ASS-S / T (Subscriber / Trunk) designed for relay line matching , ASS-7 (SS NO.7) for SS NO.7 signal processing, ASS-P (Packet) for packet call processing, and corresponding electronic switching system (typically TDX-10 or TDX-100) Are employed individually or in combination.

In addition, the INS is located at the center of the corresponding exchange system, and the INS intensively handles the number translation function, the route control function, and the space switch connection function for performing the connection between the ASS, or the connection between the ASS and the CCS. A data link is provided that connects each ASS point-to-point so that communication between each ASS can be performed only through the data link (ie, communication of information exchanged between subscribers and / or used within the system). Communication of information transmitted in order to perform the communication, and a fiber optic link is employed as a data link between the ASS and the INS. The switch employed in the TDX-10 exchange system has a time-space-time (T-S-T) switch structure by a time switch located at each ASS and a space switch located at the INS.

The CCS will perform the overall Maintenance and Administration (M & A) functions 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 the subscriber and / or the relay line, the ASS detects the occurrence of the call request and starts the call origination processing function. Or number translation is requested for the number information received from the relay line. After the INS completes the translation of the number, the INS performs the procedure of establishing an internal call path between the ASS accommodated by the calling party and the ASS accommodated by the called party through search and connection. And the called party is 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, according to the entire electronic switch system including the TDX-10 switch system, in response to a call request from the calling party's subscriber terminal, the voice channel with the called party's subscriber terminal is set from the time when the call path is disconnected. Monetary charges are added. For the monetary charges, the billing data is transferred from the ASS to the CSS, recorded on a storage medium (i.e., magnetic tape) equipped with the CSS, and based on the billing data recorded on the storage medium. The billing of the corresponding subscriber terminal is made.

Here, for example, in the case of ISDN subscribers connected to ASS-T, the charging information for the talk time is performed, whereas, for example, a personal mobile communication subscriber terminal (eg, a mobile phone or a PCS) capable of personal mobile communication, or an analog subscriber terminal. In this case, it is difficult to directly check the charging information on the talk time on the terminal. Accordingly, in the case of digital subscriber terminals and / or analog subscriber terminals, the display of call charge information is not supported, and thus, the subscriber needs to check the accumulated call charges over a certain period in real time.

Accordingly, the present invention has been made in view of the above circumstances, and a charging confirmation method in a subscriber terminal for displaying current or accumulated call charging information of a specific subscriber terminal on the subscriber terminal based on the additional service registration of the subscriber. The purpose is to provide.

In order to achieve the above object, according to a preferred example of the present invention, a plurality of subscriber stations assigned unique call numbers are accommodated, and in response to a call request from the subscriber terminal generated through the ASS, A digit transmitted in the hook-off state of the subscriber station in a state where an INS for setting a network and a CCS equipped with at least one storage medium are in charge of maintenance and maintenance of setting up a call path by the ASS and the INS. Determine the setting of the check mode of the billing information, and if the check mode of the billing information is not set, execute the call setting process by the call number from the subscriber terminal, Call charges of the subscriber terminal, which are called by the subscriber, are calculated and recorded on the storage medium of the CCS. In the switching system configured to display, when the confirmation mode of the billing information is set, only the billing information calculated during the specific period of the subscriber terminal is read out of the billing information stored in the database of the ASS accommodated by the subscriber terminal. Provided is a charging confirmation method in a subscriber terminal comprising the step of transmitting to the subscriber terminal.

According to the charging confirmation method in the subscriber terminal according to the present invention having the above-described configuration, if a specific subscriber registers an additional service for charging confirmation with the exchange system and then requests a charge confirmation additional service, By allowing the generated billing information to be displayed on the subscriber terminal, real-time confirmation of the billing information generated for the subscriber terminal is possible.

The main processor 43 includes an NTP (Number Translation Processor) and an INP (Interconnection Network Processor) that performs search and management by the call of the entire space switch.

The CCS 60 manages the CI 61 of the INS 40 and the CI 61 directly connected through the data link 50, and manages a series of operations and maintenance related functions in the system. OMP (Operation and Maintenance Processor) 62, the magnetic as a secondary storage device that is controlled by the OMP 62, the billing, statistics, maintenance, operation management information, partial shortened data of the call number assumed in the present invention is registered Tape (MT) 63, a disc (D / D) 64 controlled by the OMP 62 and containing a generic program and data, and an interaction function between an operator and a system or between an operation center and a system. And a MMP (Man Machine Processor) 65 for providing.

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.

The charging confirmation method in the subscriber station according to the present invention executed by the above configuration will be described in detail with reference to the flowchart shown in FIG.

First, the subscriber of the subscriber terminal 10 calls the operator of the VDU 70 by the 10-key of the keypad unit 11 to establish a call path and then registers an additional service of the charging confirmation function. Then, the additional service registration signal of the specific subscriber terminal 10 by the operator's operation is registered on the magnetic tape (M / T) 63 through the OMP 62 via the MMP 65 of the CSS 60. It is transmitted from the CI 61 to the CI 42 and CDL 41 side of the INS 40 via the data link 50, and from the CDL 41 of the INS 40 via the optical cable link 30. The subscriber terminal 10 is delivered to the ASP 22 through the LDL 25 and the CI 24 of the ASS 20 accommodated, so that the ASP 22 can determine that the specific subscriber terminal 10 The registration status is checked and registered in the database 23 (step 80).

In that state, if the hook-off state of the subscriber station 10 is detected by the LTAP included in the PP 21 of the corresponding exchange system 20, the call origination request of the subscriber station is sent to the CI 24. It is delivered to the ASP 22 through. Then, the ASP 22 checks the grade of the subscriber station 10 so that the outgoing tone is sent to the subscriber station 10 if the subscriber is allowed to call.

Subsequently, when the subscriber station 10 having received the dial tone is manipulated a call number for calling a specific called party's subscriber station, when the first digit is received, for example, an analysis by DTMF (not shown) is performed. The interpreted digit information is applied to the ASP 22 via the CI 24, and when the first digit is received, the switching of the dial tone is controlled.

When the predetermined number of digits are received from the calling party subscriber terminal 10 by the above process, the ASP 22 determines whether the digits are input of a confirmation key for designating an additional service for setting up a charging confirmation mode. As a result of the determination, if it is not input of the confirmation key for designating the billing confirmation additional service (that is, 'NO' in step 82), the ASP 22 transfers the control process to step 84 to perform the normal procedure. Is set to the call path to the called party's subscriber terminal.

That is, the ASP 22 requests number translation from the keypad 11 of the subscriber station 10 to the NTP corresponding to the MP 443 of the INS 40 by a normal process, and the number is translated. Upon receiving the response of the translation request, the TST channel is established between the called subscriber terminal and the ASS accommodated according to the number translation result (step 86).

If a call is established between the subscriber terminal 10 and the called party's subscriber terminal and the call is in progress, the ASP 22 releases the call from the calling party's subscriber station 10 (eg, in a hook-on state). The billing information is settled until it is notified and applied to the OMP 62 side of the CCS 60 under normal control, so that the OMP 62 is in line with the call state of the calling party terminal 10. The billing information and the like are recorded on the magnetic tape 63 (step 88).

In addition, according to an embodiment of the present invention, the ASP 22 determines whether the subscriber terminal 10 is registered in the charging confirmation additional service upon detecting the hook-off state of the calling party subscriber terminal 10 and adds the charging confirmation. If the service is registered, the billing information of the corresponding subscriber station 10 recorded on the magnetic tape (M / T) 63 under the control of the OMP 62 in step 90 is downloaded in the reverse order at the time of recording. Will be stored in the

On the other hand, according to another example of the present invention, the ASP 22 determines whether the subscriber terminal 10 is registered with the charging confirmation additional service upon detecting the hook-off state of the calling party subscriber terminal 10 and charged the billing. If the confirmation additional service is registered, the call charges calculated for each call of the subscriber terminal 10 are stored and managed in the database 23, and the magnetic tape M / T is controlled under the control of the OMP 62; 63, the billing information may be recorded.

On the other hand, the charging confirmation mode by the operation of the confirmation key for activating the charging confirmation additional service provided in the keypad unit 11 of the subscriber terminal 10 in which the hook-off state is detected as a result of the determination in step 82 described above. (I.e., 'YES' in step 82), the ASP 22 receives the designation of the charging confirmation target in step 94 after setting the charging confirmation mode in step 92.

Here, the designation of the billing confirmation object is, for example, if the digit of '9712100000 * 9712110000 *' is subsequently inputted to the special function code '**' for designation of the supplementary service, the ASP 22 returns to 'December 10, '97. It is determined in a state of requesting confirmation of the accumulated billing information from '00AM 00' to '00AM 00/11/97'. Based on the result of such determination, the ASP 22 searches the database 23 in step 96 to read the accumulated charging information corresponding to the designated charging confirmation object for the corresponding subscriber station 10, and The read billing information is transmitted to the corresponding subscriber station 10 via the PP 21 (step 98).

Accordingly, the control unit 12 of the subscriber station 10 controls the LCD driver 13 based on the charging information provided from the ASS 20 in step 100 to display the charging information on the LCD display unit 14. Will be done.

On the other hand, in the above description has been described an example in which the charging confirmation function according to the present invention is executed only for the registered subscriber terminal, it is also possible to provide a method for enabling the charging information confirmation function for the entire subscriber terminal.

In addition, the present invention is not limited to the above-described application example, and various changes and modifications are possible without departing from the technical gist and the gist of the invention for displaying the charging information on the subscriber terminal.

In particular, the present invention is applicable to a personal mobile communication terminal / digital terminal or an analog terminal capable of outputting the billing information including the ISDN subscriber terminal.

As described above, according to the charging confirmation method in the subscriber terminal according to the present invention, in response to the charge confirmation request from a specific subscriber terminal under the charge confirmation additional service provided by the exchange system, it accumulatively accumulates in a specific period of the subscriber terminal. By outputting the calculated billing information on the subscriber terminal, the subscriber can check the billing information in real time, thereby establishing a more accurate billing system.
