Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention provides a method for controlling multiple call processing tasks for one event when performing a switching service using a switching system that performs a call processing task control method, particularly a storage program control method. The present invention relates to a call processing task control method that allows arbitrary registration of services and enables successive activation of the registered services in order of priority.

(Technical Background and Problems) It is desired that an exchange system be able to easily add, delete, or change exchange services.

However, in conventional exchange systems that perform N-product program control, services are added and deleted sequentially.

In order to make changes, etc., 1. For example, insert a program corresponding to the added service, and the processing that occurs in conjunction with the addition of the program.

For example, it is necessary to conduct an overall review of the processing in the event of abnormal termination. For this reason, adding an exchange service requires a great deal of time and effort, and it is also difficult to individually provide exchange services that meet the various needs of customers.

(Object and Structure of the Invention) An object of the present invention is to solve the above-mentioned problems, and when performing an exchange service using an exchange system that performs storage program control, multiple By allowing services to be registered arbitrarily and starting the registered services in order of priority,
The purpose is to easily add exchange services, and to arbitrarily set the priority order of exchange services. Therefore, the call processing task control method of the present invention is as follows.

In a call processing task control method that executes a task corresponding to a call state and an input event type, a state storage section stores the call state, and an input event type storage stores the input event type. and a task determination table section for pre-registering priority information and contents regarding the task to be executed read out from the input event type storage section, The present invention is characterized in that desired tasks are sequentially executed based on information sequentially read out from the task determination table section based on the state, events read out from the input event type storage section, and the task priority information.

(Example of the invention) The present invention will be described in detail below based on the drawings.

The figure is an explanatory diagram for explaining the operation of a sequential activation service using the bis determination table diagram shown in FIG. 3, and FIG. 5 shows an example of a sequential activation service using the bis determination table diagram shown in FIG. 3.

In the figure, 1 is a central network control device (NG).

1-1.2-1 is the central control unit (CPU), 1-2.2
-2 is the main memory (MM), 1-3.2-3 is the signal transmitting/receiving circuit (DLC), 1-4.2-4 is the transmission interface circuit (TiF), 2 is the high-performance terminal (PC), l -5 represents a voice interface circuit (V IF).

In Figure 1, 1 in Figure 1 is the central network control device (
NC), which performs network switching. The central network control device 1 includes central control devices 1-1. Main storage device 1-2. Signal transmitting/receiving circuit 1-
3, a transmission interface circuit 1-4, etc., and network switching and the like are performed by a control program stored in the main storage device 1-2.

On the other hand, 2 in Figure 2 is a high-performance terminal (PC).

A plurality of devices are connected to the network control device 1 in a star shape to form an exchange system, and are used to process various services. The high-performance terminal 2
is the central control unit (CPU, microprocessor') 2
-1. Main memory (MM) 2-2.4N transmission/reception circuit (
DLC) 2-3. Transmission interface circuit (TiF) 2
4 and a voice interface circuit (VTF) 2-5, etc., and various services are performed by control programs stored in the main storage device 2-2.

FIG. 2 shows a state transition diagram of the basic connection service up to a call, and shows a state transition diagram of the originating/terminating separation method, which is described by focusing on the states of each high-performance terminal.

In the figure, 1 incoming call request, empty response, and response are signals sent by the high-function terminal on the calling side or the called side to the high-function terminal on the called side or the calling side via the network, as indicated by the arrow in the figure. A high-performance terminal on the originating side or the receiving side receives a signal such as the incoming call request, and uses the signal as an event to initiate a state transition.

For example, 9. Telephone A connected to the high-performance terminal on the calling side is lifted and reception of the telephone number of 1 call destination B is completed (as shown in the figure)
) Then, an “incoming call request” (■ in the figure) is sent to the called party. In response to the "request for incoming call", if the destination telephone B is idle and an "empty response" (■ in the figure) is returned to the calling party, the calling party 3 sends a ringing tone to telephone A. Then, when the called party's telephone B, which has been called by the ringing tone, is picked up (response is received), the calling party is notified of the response shown in FIG. 1, and as a result, the telephones A and B are maintained in a talking state.

FIG. 3 shows a service determination table that enables sequential activation services. A block indexed by the state number in the leftmost column in the diagram and a block indexed by the input event type in the central column in the diagram are provided, and furthermore, service priorities and contents registered in advance are sequentially incremented in the rightmost column in the diagram. A block is provided that indexes by shape.

The meanings of "empty" and "incoming request" written in the blocks in the leftmost column and the center column in the figure have already been explained in connection with the state transition of the called side shown in FIG. 2.

The rightmost row of blocks in the figure are blocks that allow the content and priority of services to be arbitrarily registered and changed independently for each telephone in response to the illustrated "incoming call request." That is, in the case of 2 illustrations,
The service for "designated subscriber incoming call rejection" registered at the address of service counter "#0" is performed first.

Then the service counter is incremented and '#1
” is provided. Here, “Designated Subscriber Call Rejection” refers to a service that accepts calls from a specific subscriber (subscriber with a specific telephone number) who has been registered in advance. On the other hand, if there is a request to receive a call from a subscriber other than the registered subscriber, the subscriber should receive services such as secondary normal call reception.
What is "Normal incoming call"?

This is to activate a service that is normally performed, such as giving an "empty response" to an incoming call request.

FIG. 4 shows an explanatory diagram illustrating an algorithm for realizing the sequential activation service according to the present invention.

Column A in the figure is the system program that controls the service (
O3), column B in the figure shows the actual service program (application program). In the figure, α indicates an input event.

Usually, a large event “α” occurs in the system program in column A.
is entered (■ in the illustration), “Check the call status number”
state (■ in the diagram). and.

The call status number, input event type, and contents registered in the service determination table in the rightmost column of FIG. 3 are read out to determine the service to be processed (■ in the diagram). If there is a service to be processed as a result of this decision (as shown in the diagram)
), perform the startup process.

Shifts to control by the B-column number-vis program.

On the other hand, if there is no service to be processed (■ in the diagram),
The series of processing ends without executing the service program in column B.

When control is shifted to the service program in column B, the predetermined service determined in state 2 shown in the figure is executed (omitted by the dotted line in the figure). Then, it is determined whether the result of the execution is a normal end or not. If YES, a series of services has been executed, so the service counter is reset to 0 and the process ends (YES in ■). ). NO
In this case, since the termination did not occur normally, the content of the service counter is incremented by "+1" (■ in the figure), and the input event that caused the activation of the service program in column B is issued in a pseudo manner (■ in the figure). ) Return to the starting point of the system program in column A, as shown by the dotted line, and restart. At this time, the content of the service counter, that is, the indicated value of the service counter in the rightmost column in Figure 3, is changed from "#0" to "#
Since the service is incremented by +1 from "#1" to "#2", etc., the service is processed sequentially starting from the service with the highest priority.

FIG. 5 describes an example of a sequential activation service using the -vis determination table shown in FIG.

Now, as shown in FIG. 3, the status number in the leftmost column is "empty" and the input event type in the center column is "incoming call request."

The case where "designated subscriber incoming call rejection (telephone number #456)" is registered in the service counter "#0" in the rightmost column and "normal incoming call" is registered in the service counter "#1" will be explained with reference to FIG. 5. do.

In the figure, when the input event "α (incoming 0 call request)" from the originating subscriber with telephone number #123 is input to the system program in column A (indicated by ■ in the figure), Fig. 3 shows the bis determination table diagram. to state “empty”, input event type “incoming request” and service counter “#0” to “
Decide whether to reject incoming calls from designated subscribers (■ in the diagram).Then,
The service program is started based on the determination (as shown in the figure)
) and the telephone number #123 information of one calling subscriber, etc. are passed to the service program in column B. The service program shown in column B executes the service of "designated subscriber incoming call rejection". That is, it is compared whether the calling subscriber's telephone number #123 matches the call rejection number #456 registered for one called subscriber (indicated by ■ in the figure).

Since the results of the comparison do not match (No in ``■'' in the figure), the value of the service counter is incremented (■ in the figure).

In order to sequentially execute the primary service, input event "α" (incoming call request) and information such as the calling subscriber's telephone number #123 are issued in a pseudo manner (■ in the figure). 2. The system program in column A in the figure. (■).

In the same way as the state (■), "normal incoming call" is determined from the state "empty", the incoming event type "incoming call request", and the service counter "#1" (as shown in the figure). Then, after starting the service program based on the determination, it is passed to the service program in column B (phase shown in the figure). The service program performs the "normal incoming call" service as explained using FIG. 3 (0 in the diagram).

(Effects of the Invention) As explained above, according to the present invention, a plurality of services can be arbitrarily registered for one event, and the registered services are sequentially started in order of priority, so that exchange services can be Add delete.

Priorities can be easily changed.
