The present invention relates to a method of implementing the registration, cancellation and confirmation functions of subscriber services in an electronic switchboard.

Conventionally, that is, TDX-1B (trademark) electronic switchboard is limited to the type of subscriber service provided, missed announcement, priority call, scheduled time notification, conference call, three-way call, speed dial, caller ID tracking The function, instant call function, standby call function, call waiting function, incoming call switching function, etc. are not diverse, and the implemented functions do not meet the needs of subscribers who want more convenient and various services by providing a limited range of services.

The present invention has been made to solve the above-mentioned conventional problems, SSCO (Subscriber Service Control) block that is responsible for the subscriber service function in the electronic switchgear provides a registration, cancellation, confirmation function for a variety of services, By introducing the subscriber key function, the security of the service has been strengthened, and the method of registering, canceling, and verifying the subscriber service to provide convenience for the writers to use the service by providing the registration, cancellation, and confirmation functions of the service even after a call is provided. The purpose is to.

Accordingly, the present invention is to achieve the above object, LTAS to control the matching of subscriber relay line, LSS to control the time division switch, R2 MFC and DTMF signal transmission and reception and SSS for generating various tones, TCS to control the general call processing overall , ASS including OSS to control various subscriber services, NHS to handle number translation and routing, INS to manage SNS to manage spatial switch and announcement guide resource and conference call resource. In the method of registering, canceling and confirming the subscriber service, the first step of preparing a service during a call when the service is attempted is analyzed by analyzing whether the service is performed during a call when the service is started, and receiving a code from the subscriber through the NHS. The second step to request translation into the third step, and the third step to implement the service with the type of service translated from the NHS. And a fourth step of determining whether there is a waiting subscriber after performing a service and receiving a hook-on or a hook-flash from the subscriber and continuing a call with an existing subscriber or ending the service.

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

1 is an overall structure diagram of an electronic switching system, and is composed of three subsystems: a central control subsystem (CCS), an interconnection network subsystem (INS), and an access switching subsystem (ASS). CCS performs operation and maintenance functions, INS performs centralized call processing function connecting multiple ASSs and CCS, and ASS performs distributed call processing function by being directly connected to subscriber line and trunk line. . OMP (Operation and Maintenance Processor) is a processor that performs the operation and maintenance functions and the main tasks, MMP (Man Machine Processor) is a processor that performs the function of handling the exchange of information between the system operator and the system, Interconnection Network Processor ) Is a processor that controls the switch of the call processing process, NTP (Number Translation Processor) is a processor that controls the number translation or routing process of the call processing process, and an Access Switching Processor (ASP) is the overall process that processes the switch subscriber or relay line signal. A processor that performs call processing.

2 is a structural diagram of subsystems for subscriber service registration, cancellation, and confirmation functions in an electronic switching system to which the present invention is applied, and controls a time division switch (LTAS) and time division switch that control the registration of a subscriber and a trunk line. Local Switching Subsystem (LSS), R2 MFC and DTMF signaling, SSS (Signaling and Service Subsystem) to generate and receive various signals, TCS (Traffic Control Subsystem) to control general call processing, and various subscriber services It consists of an optional service subsystem (OSS), a number handling subsystem (NHS) that handles number translation and routing, and a SNS (switching network subsystem) that manages a space switch, a recording announcement resource, and a conference call resource. Subscriber Service Control (SSCO), a block that performs registration, cancellation, and confirmation of subscriber services, is installed and operated in OSS.

3 is a general flow diagram when a subscriber wants to register, cancel or confirm a special service.

First, when the subscriber wants service, the system checks whether the current subscriber is in service while attempting to service (1). If the service attempt is in a busy state, it enters the busy service ready state (2), and if not, it immediately goes to the state of receiving and translating the code (3). After translating the code, the service is provided for each service (4). When the service attempted by the subscriber is over, it will listen to the tone and see if there are any subscribers waiting (5) and hook on if no subscribers are waiting, and get a hook flash if there are waiting subscribers (6 Call back to the waiting subscriber or terminate service (7).

4 is a detailed flowchart of the busy service preparation step of FIG.

The service attempt in the busy state requests the other subscriber to make a waiting sound when the hook flash comes in (2-1), and waits for the other subscriber and sends a dial tone when the waiting response is received (2-2) so that the subscriber can dial the code. (2-3). If the subscriber who hears the dial tone dials the "* (star)" or "# (sharp)" digit (2-4) in the service, the subscriber stops the dial tone and enters the code reception and translation phase.

5 is a detailed flowchart of the code reception and translation step of FIG.

When the code is received from the subscriber (3-1), the code translation is requested by the NHS (3-2). When the code translation is received from the NHS (3-3), the system checks whether there is a pending subscriber (3-4). If there are any pending subscribers, examine whether the current subscriber is a registered subscriber to call-hold service (3-5). This is because, in the electronic switching system, the function of registering, canceling and confirming the subscriber service after the call is available only to the subscriber whose call holding service is registered. If no subscriber is waiting in the state of (3-4) above or if the call hold service is registered in the state of (3-5), the system checks again whether the subscriber key is registered (3-6) and registers. If it is, it receives the key (3-7), and if it is the same as the registered key (3-8), the service is continued and if it is different, a failure sound is sent (3-9). If the subscriber key is not registered in the state of (3-6) above or is successful in the state of (3-8) above, * (star) digit is finally received along with time information, called party number, etc. according to the type of service. The lower surface system (3-10) performs the service according to the service type.

6 is a detailed flowchart of the service implementation of FIG. The system does the necessary processing with the translated service code and the necessary information. First, by looking at the translated service code (4-1), it is determined whether the service is registered, canceled, or confirmed and processed by the service processing routine (4-2). (4-3) It enables the subscriber to recognize the result of the processing of the service.

As an example of application of the present invention as described above, it is applied to TDX-10 (registered trademark), which is a domestic large-capacity electronic switchboard, and rejects incoming services, edited missed guidance, edited rejection, call retry, We added services such as call waiting, call transfer, call hold, etc., and the existing service can be repeatedly serviced at the same time every day using the code. It is divided into unconditional incoming call conversion and conditional incoming call conversion function. In case of missed guidance, registration, cancellation, and confirmation function is performed by dividing into the case of not including the time information.

In addition, the security function for the service is added by using the subscriber key. In particular, the subscriber can use the service more conveniently by providing such a registration, cancellation, and confirmation service even while talking with another person.

The effects of the present invention described above are as follows.

The present invention adds services such as call rejection, edited missed announcement, edited call rejection, call retry, call waiting, call transfer, call hold, etc. to the existing subscriber service provided by the existing electronic switchboard. Among the services of the specified time notification service, incoming call transfer, and missed call function, the service is also subdivided to enhance registration, cancellation, and confirmation functions, respectively, and adds a password function such as a subscriber key to provide security for services from others. In addition, this function can be used even after a call, thereby improving convenience of use.
