Abstract

PURPOSE: A method for controlling message queues for interprocessor communication in a wireless intelligent network system is provided to improve the reliability of the intelligent network system by controlling interprocessor communication through queue state monitoring. CONSTITUTION: A queue monitoring processor periodically obtains information of inner processors driven by a system call for saving the obtained information at a share memory area(S101,S102). The queue monitoring processor reads information saved at the share memory area periodically(S103). Queue resources threshold of the inner processors is extracted from the read information(S104). Queue resources usage of the inner processor is compared with the queue resources threshold(S105). If the inner processor uses queue resources more than the Queue resources threshold, a communication control flag is set to the corresponding processor(S106). The queue monitoring processor transmits a signal for stopping message transmission to the inner processor(S107). If the inner processor uses queue resources less than the Queue resources threshold, the queue monitoring processor checks whether the communication control flag of the corresponding processor is set as 1(S108). If so, the communication control flag is released(S109). The queue monitoring processor transmits a signal for restarting message transmission to the inner processor(S110).

Description

Method for controlling message queue using communication between processor in a radio intelligent network system

The present invention relates to message queue control for inter-processor communication in a wireless intelligent network system. In particular, the message queue state monitoring processor periodically monitors the state of a queue resource of a system, and when the queue resource is used above a predetermined threshold, an inter-processor communication state. The present invention relates to a message queue control method for processor-to-processor communication in a wireless intelligent network system for improving the reliability of the inter-processor communication of the intelligent network system by controlling the control.

In general, since the telephone was invented, there has been a quantum leap in technical terms, but there are some changes.

First, the slowdown in new phone subscriptions. As the penetration rate of the phone increased, especially in developed countries, the number of new phone subscriptions decreased and revenue growth slowed significantly. It has emerged.

Second, there is a change in consciousness of telephone users. In public telephone networks, telephone numbers have always been fixed in physical locations such as houses, apartments, offices, etc., and charges for calls have always been charged to the calling party, and there was no way for the user to control the service on his own. As a result, more and more people are expecting various types of telephony services that can support complex social activities such as changing the location of time zones, flexible call charges, and voice dialing.

Third is the introduction of the principle of competition in the telecommunications market. In order to cope with the opening of the telecommunications market, countries have separated and competed with big telecommunications companies that have gained a monopoly position, so that only companies that develop and distribute better telecommunications services faster than others can win the competition.

To respond to these changes, telecommunications service providers have added computers and service management databases that control services to existing telephone networks consisting of exchanges and transmission devices, which are responsible for the simple transfer of information. With the addition of new computers and databases, I came up with the idea of quickly providing a variety of services. This is an intelligent network that combines computer networks and telephone networks in the No.7 common line signaling method to create and manage new services quickly and conveniently by hierarchically separating simple telephone call connection and complex service control. It is gradually embodied in the concept of a system.

In other words, the intelligent network system refers to a system that a service provider can create and process a desired service by itself. The network elements of an intelligent network include Service Switching Point (SSP), Service Control Point (SCP), Service Management System (SMS), Intelligent Peripheral (IP) and services. It consists of Service Creation Environment (SCE) that creates and provides logic.

As the network service is advanced and the number of subscribers increases, there may be a plurality of SCPs among the network elements. SCP maintains a subscriber database for call processing. As there are multiple SCPs in the network, each SCP should be prepared to share databases between systems as needed.

Meanwhile, inter-processor communication in a wireless intelligent network system uses a message queue. After each processor is started up, it sends or receives messages via its queue ID and queue size. In the current wireless intelligent network system, there is no message queue status monitoring and control function. However, when a certain amount of queue size is reached, the queue is cleared unconditionally, and unprocessed messages are lost during communication between processors.

In addition, even if the queue size reaches a threshold, message transfer control between processors is not performed, causing a queue full, causing a fatal failure in an intelligent network system.

Accordingly, the present invention has been proposed to solve various problems occurring in the conventional wireless intelligent network system as described above.

An object of the present invention is to periodically monitor the queue resource state of a system through a message queue state monitoring processor, and to control the inter-processor communication state when the queue resource is used above a predetermined threshold, thereby improving the inter-processor communication reliability of the intelligent network system. The present invention provides a message queue control method for interprocessor communication in a wireless intelligent network system.

The present invention for achieving the above object,

By operating a processor that monitors the status of the message queue, it periodically monitors the status of the message queue used for interprocessor communication. When the queue resource is used above the threshold, it sends a signal to the processor to control the interprocessor communication status. It prevents the loss and improves the reliability of the intelligent network system.

That is, the message queue status monitoring processor is driven by all internal processors and finally by the daemon processor. The message queue status monitoring processor has a shared memory in the form of a structure having fields such as a generation processor ID, a queue ID, a source processor, a destination processor, a queue resource usage, a queue resource quota, and a queue resource usage threshold. After the Message Queue Health Monitor is powered up, it uses system calls to obtain information about the Processor ID, Queue ID, Source Processor, Destination Processor, Queue Resource Usage, Queue Resource Usage Thresholds, etc. Write periodically to the memory area.

In addition, after reading the threshold from the data file with information about the queue resource usage threshold, the processor that periodically detects the queue size above the threshold compared to the message queue usage of each driving processor sends the message to the source processor that sends the message. Stop sending a message by sending a stop signal, and control to resume communication by sending a signal to the source processor when it falls below the message queue resource usage threshold.

Hereinafter, described in detail with reference to the accompanying drawings, preferred embodiments of the present invention according to the spirit as described above.

1 is a schematic block diagram of a wireless intelligent network system to which a message queue control method for inter-processor communication is applied in a wireless intelligent network system according to the present invention.

Here, reference numeral 100 denotes a main processor for controlling the overall operation of the intelligent network system, and reference numeral 200 denotes a queue monitoring processor for monitoring the status of the message queue. Also, reference numeral 300 denotes a memory area of the queue monitoring processor 200, in which processor ID, queue ID, source processor, destination processor, queue resource usage, queue resource quota, and queue resource usage threshold information are periodically recorded. It denotes a memory, and reference numeral 400 denotes an operator matching portion.

Reference numerals 510, 520, 530, and 540 denote internal processors, and reference numerals 610, 620, 630 and 640 denote message queues connected to the respective internal processors 510, 520, 530 and 540, respectively.

The intelligent network system configured as described above, when the main processor 100 is driven first, drives the respective internal processors (processors 1,..., Processor n).

The driven internal processor performs interprocessor communication through the message queue (message queue 1, ..., message queue n).

Next, when the internal processor is driven, the queue monitoring processor 200 is finally driven to operate as a daemon processor.

Here, the queue monitoring processor 200 configures a structure having fields of processor information and queue information data representation format as follows for processor information and queue usage information.

typpdef struct q_audit_file {

int proc_id;

int msgq_id;

int src_proc;

int dest_proc;

int max_q_size;

int use_q_size;

......

}

The driven queue monitoring processor 200 periodically records the internal processor information and the message queue usage information driven through the system call in the shared memory 300 area.

The data format recorded in the shared memory 300 for queue monitoring and control is shown in Table 1 below.

Processor ID Queue ID Send processor Receiving processor Queue depth Queue usage 1111 1000 2222 1111 102400 1024 2222 2000 3333 2222 102400 2048 3333 3000 1111 3333 102400 4096

Next, the queue monitoring processor 200 periodically reads the queue resource utilization rate (use_q_size / max_q_size) of each driving processor from the shared memory 300, calculates and compares the queue resource threshold utilization rate with the queue resource threshold utilization rate read from the data file. If the utilization is greater than or equal to the threshold utilization, a message transmission stop signal is sent to the source processor (the processor sending the message to the queue). In addition, when the queue resource utilization drops below the threshold utilization, a message transmission resume signal is sent to the corresponding source processor.

Here, the method for controlling queue status monitoring and communication periodically after driving in the queue monitoring processor 200 is as follows.

..............

q_flag =; <-Flags for controlling queue communication

use_q) rate = (use_q) size / max_q_size) <-calculate queue resource utilization

compare (use_q) rate, limit_q_rate) <-compare queue resource utilization with a threshold

src_proc = proc_id, q_flag = 1 <-set queue control flag with processor above threshold

if (q_flag == 1)

signal_send_quit (src_proc); <-Send message stop signal to processor above threshold

signal_send_start (src_proc); <-Send message resume signal to processor above threshold

Next, the queue monitoring processor 200 outputs the queue information of the shared memory 300 to the operator matching unit 400 as a text or a graph, processes an alarm when the threshold value is used or more, and sets the queue resource threshold in the data file. By making adjustments, the system's operational functions are improved.

2 is a flowchart illustrating a message queue control method for inter-processor communication in a wireless intelligent network system according to the present invention.

As shown in the drawing, when the main processor of the intelligent network system is driven, the main processor drives the internal processor. The driven internal processor then performs interprocessor communication via the message queue.

The queue monitoring processor is then run last, acting as a daemon processor.

When the queue monitoring processor is driven, information about a processor that is driven through a system call is periodically acquired in step S101, and the information about the processor is stored in a shared memory area in step S102. The processor information driven here is a processor ID, a queue ID, a queue resource usage amount, a queue resource allocation amount, a queue resource threshold value, and the like.

Next, in step S103, information of a driven internal processor stored in the shared memory area is read periodically. In addition, in step S104, the queue resource threshold value of the internal processor is extracted from the read information, and in step S105, the queue resource usage amount of the processor is compared with the queue resource threshold value.

When the internal processor driven as a result of the comparison uses the queue resource above the queue resource threshold value, the process moves to step S106 to set a communication control flag to the corresponding internal processor. The flag set here is "1".

In step S107, a signal is sent to the internal processor to stop transmitting a message, thereby stopping message transmission. By doing so, it is possible to prevent the use of queue resources above the queue threshold, thereby preventing data loss, and to maintain communication during internal processor communication.

Next, as a result of comparing the queue resource usage and the queue resource threshold of the driven internal processor periodically, if the driven internal processor uses the queue resource below the queue resource threshold, the process moves to step S108. It is checked whether the communication control flag of the processor is set to "1".

If the communication control flag of the internal processor is set to "1" as a result of the check, the control proceeds to step S109 to release the communication control flag set for the processor. That is, the communication control flag of the internal processor is set to "0".

Thereafter, in step S110, a signal for resuming message transmission is transmitted to the internal processor, so that communication with other processors is facilitated through the message queue.

According to the present invention described above, the "message queue control method for inter-processor communication in a wireless intelligent network system", the inter-processor communication state can be controlled by monitoring the queue state during message queue communication between internal processors, thereby improving the reliability of the intelligent network system. There is an advantage to this.

In addition, by periodically generating the message queue information between the internal processors of the wireless intelligent network system in the shared memory to inform the operator through the operator matching unit, and also performs an alarm processing function has the advantage of providing the operator with convenience in system operation.
