Abstract

PURPOSE: A method for allocating and processing many phone numbers to a single subscriber terminal is provided to simply implement an MBS(Multi-Bell Service) function by allocating a plurality of phone numbers to a subscriber terminal connected to a physical subscriber line. CONSTITUTION: If a destination number open command is inputted through the OMP of a CCS(Central Control Subsystem) from an operator terminal in the case of newly opening 'xxx-yyyy' as the first phone number(70), an R_PFXTBL and an R_PFXINFTBL executes verification for the prefix(xxx)(72). If the prefix is acceptable(74), the R_PFXTBL and the R_PFXINFTBL stores the destination number(yyyy) in an R_TDNTBL together with ASP information and line information(76). If the destination number is normally installed(78), the telephone number(xxxyyyy) is stored in the subscriber calling number information of an R_SUBS_DATA(80).

Description

How to deal with multiple phone number assignment to a single subscriber terminal {METHOD FOR ASSIGNING PLURAL TELEPHONE NUMBERS TO A SUBSCRIBER TERMINAL}

The present invention relates to a multiple telephone number assignment control method for a single subscriber terminal, and more particularly, to assign a plurality of telephone numbers to a subscriber terminal connected to one physical subscriber line accommodated in an exchange and to process a call. The present invention relates to a multiple phone number assignment control method for a single subscriber station for the purpose of making a call.

An exchange that supports multiple subscriber terminals to make or receive calls by occupying subscriber lines has an ASS (Access Switching Subsystem) and centralized call processing that handles the function of making and receiving desired calls by connecting multiple subscriber terminals. It is composed of INS (Interconnection Network Subsystem) which performs routing function and Central Control Subsystem (CCS) which performs overall operation and maintenance function of exchange.

In such an exchange, when a calling party makes a call through a subscriber terminal, it determines whether it is possible to make a call in response to the occurrence of the call, allocates a subscriber signal, and transmits a dial tone to the calling subscriber terminal. When the telephone number is dialed from the calling party's terminal in response, the exchange receives the dial digit, translates the telephone number (translation of the station number and the called number), and then calls the translated station number and the called number. .

However, in most cases, in order to efficiently use telephone number resources and simplify the billing number system, the exchange is limited to a single telephone number per single subscriber line. Therefore, various service developments are required. The situation in the environment poses significant constraints on the development of new functions.

That is, a service that provides a plurality of telephone numbers with different ringing tones to subscribers or special services for incoming telephone numbers is difficult to implement by a single telephone number allocation principle in one subscriber line.

Accordingly, the present invention has been made in view of the above-described circumstances of the prior art, and assigns a plurality of telephone numbers to a subscriber terminal connected to one physical subscriber line, such as a multiple incoming service required by an operator or a multi-bell service. It is an object of the present invention to provide a method for assigning multiple phone numbers to a single subscriber station in order to simplify the functioning.

In order to achieve the above object, according to a preferred embodiment of the present invention, a new command of a first telephone number including a station number and a called number is input from an operator terminal into a database, and the station number is responded to in response to the new command of the telephone number. Search the data table of the database for storage to verify the acceptance of the station number of the telephone number. If the acceptance of the station number is verified, the telephone number of the telephone number is stored in a data table for storing the called party number and storing subscriber information of the database. When a command for storing a called number and storing subscriber information and assigning a plurality of second telephone numbers for the first telephone number is input from the operator terminal, the data table for storing the station number of the database is stored. Verifies whether the second telephone number is accepted for the station number; and the second telephone number Storing the called number of the second telephone number and storing the subscriber information in the data table for storing the called number and storing the subscriber information of the database when the acceptance of the station number is verified. Number assignment processing is provided.

According to the present invention, when storing the called number of the telephone number, corresponding ASP and line information is also stored.

Preferably, the called number of the first and second telephone numbers and the data table of the database for storing subscriber information are allocated to different areas.

According to the multiple phone number assignment processing method for a single subscriber station according to the present invention, a subscriber station is configured by constructing a database of a plurality of telephone numbers for a single subscriber station connected to one physical subscriber line accommodated in an exchange. Various incoming services, including incoming bell service, will be available.

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

1 is a view showing a schematic configuration of an exchange to which the present invention is applied, the exchange having an ASP 20a for accommodating a subscriber station 10 to control a processing function of a call generated from the subscriber station 10. CCS with ASS 20, INS 30 with NTP 30a connected to the ASS 20 and responsible for number translation, and OMP 40a for overall operation and maintenance of the exchange. 40, the operator terminal 50 for allocating a plurality of telephone numbers to a specific subscriber station 10 in accordance with the present invention is linked to the OMP 40a of the CCS 40.

FIG. 2 is a view for explaining the structure of a database constructed when a plurality of telephone numbers are assigned to a single subscriber station 10 according to the present invention in the exchange shown in FIG.

With reference to the drawings, the database includes R_PFXTBL 60 and R_PFXINFTBL 62 in which a station number 'xxx' is stored when a telephone number of 'xxx-yyyy' is established, for example, by a command from the operator terminal 50. And R_TDNTBL 64a in which the incoming number ('yyyy') is received and the corresponding ASP 20a and line information are stored when the station number is accepted by verification of the R_PFXTBL 60 and R_PFXINFTBL 62. When the incoming telephone number is normally established in the R_TDNTBL 64a, the R_SUBS_DATA 66a stores subscriber information, and a plurality of telephone numbers (for example, 'xxx-zzzz') are stored in the subscriber terminal 10. In the case of allocation, the R_TDNTBL 64b storing the called number 'zzzz' for the plurality of telephone numbers and storing the corresponding ASP 20a and line information, and the called telephone number in the R_TDNTBL 64b. Is newly established, R_SUBS_DATA (66b) for storing subscriber information It is hereinafter.

Therefore, considering the case where a plurality of telephone numbers are assigned to one physical subscriber line in the database, for example, the operator according to the procedure for establishing 'xxx-yyyy' as the first telephone number (called number) From the terminal 50, the incoming number establishment command (CRTE-SLN: DN = xxxyyyy, ASP = ASPkk, LINE = 1 ...) is input through the OMP 40a of the CCS 40 (step of FIG. 3). 70).

When the subscriber's called number is newly established from the operator terminal 50, verification of the station number 'xxx' is performed on the R-PFXTBL 60 and the R_PFXINFTBL 62 (step 72 of FIG. 3). When the verification result is possible to accept the station number (YES in step 74 of FIG. 3), the called number 'yyyy' is stored in the R_TDNTBL 64a including the ASP and line information (FIG. 3). Step 76).

Then, when normal establishment of the called number is made (YES in step 78 of FIG. 3), the telephone number of 'xxxyyyy' is stored in the subscriber calling number information of the R_SUBS_DATA 66a (step of FIG. 3). 80).

In addition, when allocating a plurality of telephone numbers in a state in which a subscriber's telephone number is newly established by the above process, a multiple telephone assignment command ('REG-SSVC: DN = xxxyyyy, SSVC = MBS,) from the operator terminal 50 is assigned. ODN = xxxzzzz) is set, and when the command is input, the data for 'xxxyyyy' number is retrieved from the database (step 80 of FIG. 3) to check the ASP and line information where the corresponding subscriber terminal is located (FIG. 3). Step 84).

When the confirmation is made, the verification (step 86 of FIG. 3) for the station number ('xxx') is performed in the same manner as the above process, and if the acceptance of the station number is possible, the procedure of steps 76 to 80 is performed. It stores the number 'zzzz' and stores the subscriber information.

Here, the call related information stored in the second telephone number (ie, 'xxxyyyy') must be the same as the first telephone number ('xxxyyyy').

That is, when a plurality of telephone numbers are assigned to one physical subscriber line (ie, subscriber terminal 10) by the above process, the plurality of called numbers are stored in the same manner as the existing number information. Changes in the number translation function due to the implementation are not incurred, and the information (caller information in case of multiple caller numbers and ringer information in case of MBS (multi-bell service)) is transmitted to the called party to distinguish the phone number used for the call. Only the function to add is added.

In addition, according to the present invention, the management of a plurality of telephone number data is divided into a station number and a called number, but a plurality of called numbers are also used for incoming calls to the subscriber terminal 10. Number in the same way, and assigning a plurality of telephone numbers to a single physical subscriber line as it is possible to assign a second telephone number to a subscriber who has previously registered the first telephone number. This is done simply.

In addition, it is possible to add information indicating that a plurality of called numbers are used to distinguish a plurality of called numbers (telephone numbers) and the first telephone number assigned to the first subscriber, and to add ringing bell information for the MSB function.

In addition, according to the present invention, the telephone number stored in the subscriber data is limited to the first telephone number to be projected at the time of the subscriber's establishment, and the plurality of incoming telephone numbers subsequently applied to the subscriber are stored in a separate subscriber database. In addition to the incoming call will be used as information to distinguish the calling subscriber.

Therefore, according to the present invention, a plurality of telephone numbers are allocated to and stored in a subscriber station 10 connected to one physical subscriber line in a database of the type shown in FIG. Done.

As described above, according to the method for assigning a plurality of telephone numbers to a single subscriber station according to the present invention, a ringing service is included by allocating a plurality of telephone numbers to a single physical subscriber line (ie, subscriber terminal) and storing them in a database. It is possible to provide a variety of incoming services.
