The present invention relates to a method for interworking an internal call provided between an analog subscriber and a digital subscriber in an electronic switching system.

Conventionally, subscribers connected to an electronic switching system have been providing an analog intercall processing service to subscribers using only an analog telephone.

With the advent of digitalization of circuits and the integrated service digital network (ISDN), which meets the various service needs of subscribers, the types of terminals that subscribers can accommodate are diversified. In the future, it is essential that the system interoperate with terminals used in ISDN environments such as digital phones and terminals used in PSTN environments such as existing analog phones. This necessitates a subscriber service between the existing analog phone and the new digital phone.

Accordingly, an object of the present invention is to provide a local call processing service between subscribers connected to an electronic switching system regardless of the type of analytical / digital telephone of a subscriber, thereby increasing the modularity, scalability, and efficiency according to the acceptance of each subscriber. It is to provide an interworking method.

In order to achieve the above object, the present invention, if the subscriber or the digital subscriber is a subscriber that can not handle the originating process by checking whether the subscriber is capable of the originating process by picking up the handset, In the case of the first step of receiving the called number, and after performing the first step, the number translation processor analyzes the called number to determine the called party.If the called number translation decision and the called party are subscribers in the same exchange, the called processor In the second step of making an incoming call request, and after performing the second step, the called processor checks whether the incoming call processing is possible and notifies the incoming call if the incoming call processing is impossible, and if the incoming call processing is possible. The incoming call processor notifies the calling processor about incoming call occupancy and A third step of exchanging information, and a fourth step of terminating after making a call between an analog subscriber and a digital subscriber in a call path connected between originating and receiving after performing the third step. .

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

1 is a hardware configuration diagram of an electronic switching system to which the present invention is applied, (1) shows an Access Switch Subsystem-S (hereinafter referred to as ASS-S), and (2) shows a network subsystem ( Inter Connection Subsystem (hereinafter referred to as INS), (3) Central Control Subsystem (hereinafter referred to as CCS), and (4) Digital Switch Access Subsystem (hereinafter referred to as ASS-S). (5) and (6) are called Access Switching Processors (ASPs), (7) are Number Translation Processors (hereinafter referred to as NTPs), and (8) are connected network processors ( Interconnection Network Processor (hereinafter referred to as INP), (9) and (10) denote Time Switch Processor (hereinafter referred to as TSP), respectively.

The ASS (1, 4) is equipped with subscriber and relay line matching, various signaling devices, time switches, etc. to perform most call processing functions and self-maintenance functions, and have a horizontally distributed structure in a system.

The INS (2) functions to connect the ASS (1, 4) to each other or between the ASS (1, 4) and the CCS (3) based on the center of the system, and the space switch is located there. In addition, it performs number translation, routing, and space switch connection functions among call processing functions, and is also responsible for generating and supplying a system clock with a network synchronizer.

CCS (3) is a subsystem that performs the overall operation management function of the system. It controls the system-level maintenance, test and measurement, billing and statistics, as well as the auxiliary storage disk drive and magnetic tape drive, and the operator matching function. to provide.

The main software block for call processing is the Analog Subscriber Control (ASC) block in the ASP (5, 6) and the Digital Subscriber Control (DSC) block. The NTP 7 loads a Number Translation (hereinafter referred to as NTR) block into each processor. Incidentally, in the drawing, a thick solid line passage represents a currency path.

2 is a detailed flowchart of the present invention.

When the analog subscriber in the ASS-S 1 picks up the receiver, the analog call originating call processing request is received by the ASC of the internal ASP 5 (11). The ASC of the ASP 5 then checks whether the subscriber is capable of outgoing subscriber status (12).

If the subscriber is not able to handle outgoing call, the calling subscriber is notified through the tone or announcement broadcast (13), and if the subscriber is able to make outgoing call, the incoming number is received (14). In the NTR of (7), the called party is analyzed to determine the called party (15).

If the incoming call is a digital subscriber in the same exchange, the incoming call request is made by DSC of the internal ASP 6 of the ASS-I (4). The DSC of the internal ASP 6 of the ASS-I 4 then checks whether the subscriber's status is capable of incoming processing (16). If the subscriber is unable to handle the call, the caller of the ASS-S 1 is notified of the call through the tone or announcement broadcast (17).

In case of subscriber who can handle incoming call, DSC of ASS-I (4) internal ASP (6) informs ASC of ASS-S (1) internal ASP (5) to inform the ASC of ASS-S (1) internal ASP (5). Give and take (18). Then, after the call is made (19) between the call originating subscriber and the digital called subscriber in the call path connected between the originating and the incoming call (dashed line passage of FIG. 1).

On the other hand, when the digital subscriber receiver in the ASS-I 4 is received, the digital outgoing call processing request is received by the DSC of the internal ASP 6 of the ASS-I 2 (11). The DSC of the ASP 6 checks whether or not the subscriber state capable of originating processing for the subscriber (12).

In the case of a subscriber who cannot process calling, the calling subscriber is informed of the tone or announcement with the display information displayed on the display device (13).

If the subscriber is capable of originating, the receiver receives the called number (14), and determines the called party by analyzing the called number in the NTR of the NTP 7 (15). If the incoming call translation result is an analog subscriber in the same exchange, the incoming call request is made to the ASC of the ASP (5), and the ASC of the ASP (5) checks whether or not the status of the subscriber can be processed (16).

In the case of a subscriber who cannot process an incoming call, the calling subscriber is informed of the tone or announcement with the display information displayed on the display device (17). In the case of a subscriber who can handle an incoming call, the ASC of the ASP 5 notifies the DSC of the incoming call 6 to the DSC of the ASP 6 to exchange information necessary for call processing with each other (18). Then, the call is terminated after the call is made between the calling subscriber and the called subscriber in the digital communication channel.

Therefore, the call processing is performed between the analog subscriber and the digital subscriber, thereby improving the scalability, modularity, and efficiency for accepting the analog / digital subscriber of the exchange.
