Abstract

PURPOSE:To execute communication service processing at high speed and efficiently, and to improve performance by generating previously plural processes corresponding to each service at every time to start up system, and retrieving and executing one process among the generated processes when a start request arises. CONSTITUTION:When a process generating part 11 is started at the time of the start-up of the system, etc., the prescribed number of the processes (x) are generated by a service application process generating means 111 for one kind of the service, and a queue is formed in a process queue 14. Subsequently, another process (y) is generated similarly. Next, when the start request arises, a process starting part 12 starts operation, and a start waiting queue retrieving means 121 retrieves the queue 14, and takes out the process corresponding to the kind of the requested service, and service start request is informed by a start request informing means 122. After finish, a process executing part 13 holds itself in readiness without eliminating said process but initializing it. Thus, the processing is speeded up, and the performance is improved.

Description

[Detailed Description of the Invention] [Summary] Regarding a service process management method in an application processor installed in a communication system, the present invention aims to reduce overhead caused by processing other than communication service processing and provide high-speed communication services. A process generation unit, a process activation unit, and a process execution unit are provided, and the process generation unit generates a plurality of application processes for each service type in advance by a service application process generation unit, and creates a process queue for each type by a startup queue formation unit. The process startup unit is driven by an instruction from the process execution unit, searches for one process of the type corresponding to the instruction from the process queue using the startup waiting queue search means, and sends a request to the searched process from the start request notification means. A startup message is notified, and the process execution unit is configured to manage the execution of the process started by the process startup unit.

[Industrial Application Field] The present invention relates to a service process management method in an application processor provided in a communication system.

In recent years, various services have come to be provided by application processors connected to exchanges, particularly in PBX (private branch exchange) technology, with hack-end connections (connected to the rear of the exchange when viewed from terminals). Terminals with character display functions (such as multi-function telephones) are connected to such exchanges, and data other than voice can be transmitted, and the service process provided by the application processor provides various communication services, such as forwarding. services, voice mail, bulletin board services, etc.

When an application processor provides a communication service, part of the communication processing (for example,
In the case of a transfer service, real-time performance is required because the application processor holds the data at the transfer destination and the process of searching for that data is performed on this application processor. However, with application processors, actual processing is performed only after initial settings and other steps are performed when a process is started, so it takes time to provide services.

Therefore, the overhead of starting the service process on the application processor is reduced,
It is desired to perform faster processing.

[Prior Art] FIG. 9 shows a system configuration diagram of a conventional example, and FIG. 10 shows a flow diagram of the conventional example going to an application processor.

In FIG. 9, a multifunctional terminal device 9 equipped with a display screen
0 is accommodated in a network 91 of multiple exchanges, and the exchanges are controlled by a call processor 92 (indicated by CP).゛? The application processor 93 is hack-end connected to the exchange, and when a service request is made from the terminal device 90, the call processor 92 controls the network connection and the application processor 93
connected to. The application processor 93 executes services using corresponding application programs in response to requests from terminals. Application processor 93 accesses file device 94 as needed.

The service process management method in the application processor 93 will be explained using the conventional flow diagram shown in FIG.

The program that performs process management waits for an event (100), and issues a process activation request to the basic software when a process request event occurs (101). As a result, the specified service application process is activated (102).

When starting a process in the process management program is completed, initial settings are first performed inside the next started process (104). In this initial setting, processes such as acquiring a memory area and loading a program for executing the requested service into the memory area are performed. Next, service processing is performed (105), and it is determined whether the processing has ended (106, 107), and if it has ended, the process is destroyed.

[Problem to be solved by the invention] According to the conventional method, it is necessary to start a process every time there is a request to start a service, and actual communication service processing is performed only after a service request is received. You must first start the process and perform initial configuration.

However, when there is a request for a service, processing of the service includes processing such as starting a process and initializing it, which creates a problem in that there is a large overhead in areas other than the actual communication service.

An object of the present invention is to provide high-speed communication services by reducing overhead due to processing other than communication service processing.

[Means to solve the problem] FIG. 1 is a diagram showing the basic configuration of the present invention.

In FIG. 1, 10 is an application processor;
Reference numeral 11 represents a process generation unit that generates a process in advance, 12 a process activation unit, 13 a process execution unit, and 14 a process queue.

The present invention generates a plurality of processes corresponding to each service in advance in the process generation unit, and when an activation request occurs, one of the generated processes is extracted and passed to the request source to start operation, and the process is executed. The process is carried out in the section.

[Operation] The process generation unit 11 is activated at system start-up or idle time processing. Then, the service application process generation means 111 generates a service application process X of one service type, and the process X is connected to the process queue 14 in the next startup queue formation means 112. When a predetermined number of service application processes When a predetermined number of process queues of each type are created, the processing of the process generation unit ends.

Next, when a startup request occurs, the process startup unit 12 starts operating, and the startup waiting queue search means 121 searches the process queue 14 and selects the first free process from the process queue corresponding to the requested service type. Take out the
The start request notification means 122 notifies the searched process of a service start request.

When the process execution unit 13 receives the start request notification, it executes the service processing in the corresponding process, and upon completion, the process is initialized and waits for receiving the next service start request without destroying the process.

In this way, before a service process startup request occurs, multiple processes corresponding to each service type are generated in advance and prepared in a waiting state, and when a process startup request occurs, they are immediately started and executed. This makes it possible to reduce overhead due to processing other than service processing.

[Example] Figure 2 is a configuration diagram of an embodiment of the present invention, Figure 3 is a flow diagram at system startup, Figure 4 is a flow diagram at process startup, and Figure 5 is a flow diagram inside each service process. Figure 6 is an explanatory diagram of processes and process startup queues, Figure 7 is an explanatory diagram of multiple types of processes,
FIG. 8 is an explanatory diagram of the relationship between a process queue and a process management table.

In FIG. 2, 20 is a multi-function terminal, 21 is an exchange network, 22 is a control processor (indicated by CP) that controls the exchange network, and 23 is a central processing bag (VCP).
The application processor (AP) including u and memory
24 to 27 indicate the software configuration of the application processor, 24 is the operating system (displayed as O8), 25 is a communication control unit that executes communication with the terminal and the exchange, and 26 is the service process generation and terminal 27 is a service program area in which each generated service process is stored, 28 is a startup queue, and 29 is a process management table.

When a call is made from the multi-function terminal 20 in FIG. 2 and a dial is made to request application service, the connection is made to the AP 23 via the exchange network 21, and the communication control unit 2
5 via 0324. Corresponding services are executed by the processes of the service process management unit 26 and the service program area 27.

When the system is started up, the service process management section 26 generates a process according to the flow shown in FIG.

To explain FIG. 3, first, in response to a system startup input, a service application process of a predetermined service type, for example, service A, is started (30), and the process is started (memory area settings, program When the process is completed, the process identification number (ID) is placed in the startup queue (Q
(displayed in UEUE) 28 (see Figure 2), which leads to (32
). As a result, one of the processes 271 of service A is created in the service program area 27 and enters a startup waiting state.

It is determined whether the specified number of processes of this service type A have been started (33, 34). If the specified number has not been reached, the process returns to step 30, and if the specified number has been reached, other service types B, C (processes The specified number of processes (272 and 273) in Figure 2 are activated in sequence, and each time it is determined whether the activation has been completed for all types (35.36).

If startup has not been completed for all types, the process returns to step 30 and the same operation is repeated for other types of processes. When the specified number of processes for all processes are started, the process moves to the next state (other processing).

Next, when a process activation request is generated in response to a service request from the user (multifunction terminal 20), the process is activated in the service process management unit 26 according to the flow shown in FIG.

To explain FIG. 4, the service process management section 2
The startup processing program for process No. 6 waits for an event (41), and when a process startup request event occurs (42), it fills the startup waiting queue (Q) for the specified process.
Displayed on UEUE, it is determined whether there is a process connected to 28) in FIG. 2 (43, 44), and if there is, the first process on the queue is attached (released from the queue) (45). Next, it makes a request and attaches (creates) the process to the user's process management table (29 in FIG. 2) L (46), and notifies the originator of the process request of the process activation (47). The above station
When it is determined in the module 44 that the designated process is not connected to the activation waiting queue, a busy (BUSY) message is returned to the activation request source.

Next, the flow inside each service process will be explained with reference to FIG.

First, according to the system startup flow shown in Figure 3,
A process is generated, initialization 1 (reserving a memory area, loading a program, etc.) is executed, and the process is connected to a process queue and in a waiting state (indicated by WAIT). At this time, when a service start request message is input by notification to the startup source in step 47 of the process startup flowchart in FIG. 4, the service process in FIG. 5 executes service processing from the standby state. state (52). When the process is completed, initialization 2 is performed for the process. This initial setting 2 initializes each value so that the process can be used again without disappearing, whereas the conventional process disappears when the process ends. Next, a termination notification is sent to the process management, and this process becomes a new process in a standby state.

Next, the relationship between the process, the process startup queue, and the process management table will be explained using FIGS. 6 to 8.

FIG. 6 shows how a plurality of processes A of service type A are sequentially generated by the service process management unit 26 according to the flow shown in FIG. 3 above.

When each process A is generated, each process ID is stored in the process A startup queue (QUEUE) 291,
Pointers for each process ID are sequentially linked in a chain.

FIG. 7 shows that after a plurality of processes 8 are generated as shown in FIG. 6, the service process management unit 26
The figure shows how processes of service types B and C are generated and their activation queues are formed.

FIG. 8 shows the process management table 2 of user S when user S requests process B while executing process A.
91 is shown. In this case, user S uses process A (
After executing the process ID OX＊＊＊), by making a startup request for process B, which is a different service type, the ID at the head of the process B startup queue 282 is changed to “
By activating the process 0X001'', the process type B and ID are stored in the process management table 291 of the user S as shown in the figure.

In the above embodiment, the system waits for a startup request message (W
AIT) state and suspends the processing of the application process at - time, but one way to temporarily suspend this processing is to set it in a state where it does not accept messages (for example, "5").
It is possible to use a command (for example, using "WAKEUP") to start processing from this state (using "LEEP").

[Effects of the Invention] According to the present invention, when executing communication service processing, it is possible to execute the process without starting a process with a large overhead, so that communication service processing can be performed quickly and efficiently. It is possible to achieve improved functional performance.
