Integration method of service exchanger module, service control module and intelligent information system module in intelligent network exchange system

The present invention relates to an intelligent network switching system according to the ITU-T Q.1200 series recommendation, and in particular, to a service exchanger module (SSM) and service control of an intelligent network switching system implemented in each of the separate machines according to the recommendation. Module (SCM), intelligent information providing system (IP) to a method of integrating and implementing on a machine.

The general structure of the Advanced Intelligent Network (AIN) is in accordance with the ITU-T Q.1200 Series Recommendations, Service Switching Module (SSM), Service Control Module (SCM) and Intelligent Information System (SCM). Intelligent Peripheral (IP) module. In particular, the ITU-T Q.1200 Series Recommendation recommends that each module be divided into separate commercial systems, or integrated into one system. Here, a system refers to machines having a real hardware configuration, which is usually implemented as a workstation or a personal PC.

On the other hand, as shown in Figure 1, each module of the conventional intelligent network switching system uses a socket (Communication) communication based on the TCP / IP network (Communication) necessary messages and generated messages with other modules The operation of transmitting and receiving is performed. In particular, each module is implemented on a separate machine, and this structure is recommended for providing a large capacity intelligent network switching system.

1 is a diagram showing the internal architecture of a conventional intelligent network switching system, and shows that the service switch module (SSM) 110, service control module (SCM) 120, intelligent information providing system (IP) module 130. The modules are implemented on an independent machine in a high-capacity intelligent network system, and each module transmits necessary and generated messages using socket connections based on TCP / IP.

FIG. 2 is a diagram illustrating a message transmission mechanism between modules in a typical intelligent network switching system, in which a process generated in a module transmits a message to another module according to a need of a service or a function. Referring to FIG. 2, a message transmission state between modules of a typical intelligent network switching system is described. A process 213 in one module needs a predetermined function or service and requires communication with another module. The message is sent to the Tx Part process 210. Then, the Tx part process 210 calls the corresponding routine, and the called routine periodically reads the message written to the message queue 212 and sends the read message to the counterpart module. Will be sent. The message transfer is made over a TCP / IP socket connection and sent to the Rx part process 220 of another module. At this time, the Rx part process 220 analyzes the transmitted message and transmits it to the corresponding process according to the analysis result, and is temporarily recorded in the message queue 222 of the corresponding process before the message is transmitted to the process.

FIG. 3 is a diagram illustrating a message transfer algorithm according to the inter-module message transfer state described with reference to FIGS. 1 and 2. FIG. .

In the algorithm shown in FIG. 3, the process of establishing a socket connection with the Rx part process 220 by the Tx part process 210 (step 312), and generates a message queue 212 that receives a message transmitted by each process created in the module. (Step 314), and the process of repeatedly reading the message queue 212 by the Tx part process 210 and transmitting a message to the Rx part process 220 (step 316) is performed at the transmitting side. The partial process 220 receives the socket connection request of the Tx partial process 210 to establish a connection and waits for a message (step 322), and repeatedly transmits the transmitted message to the message queue 222 of the corresponding module. A process (step 324) is performed at the receiving side.

However, in the intelligent network exchange system structure and message transmission as shown in FIGS. 1, 2, and 3, each module operates under the assumption that each module is implemented on a separate commercial host, that is, machines. Due to limitations, it is difficult to prepare various platforms in implementing the actual intelligent network switching system service. In addition, since each module must be provided with a separate machine, there is a problem in that additional cost occurs even in a situation that does not require a large capacity intelligent network switching system service.

Accordingly, an object of the present invention is to provide a service exchanger module (SSM), a service control module (SCM), and an intelligent information provision system of an intelligent network switching system implemented on each of separate machines according to the ITU-T Q.1200 series recommendation. (IP) is to implement the method to integrate the module into one machine.

In addition, an object of the present invention is to propose a method for implementing an intelligent network switching system that can be implemented according to various platforms in the implementation of each module implemented in the intelligent network switching system.

In order to achieve the above object, the present invention provides a method for implementing an intelligent network switching system module, the process of generating independent Rx part and Tx part processes in the IP, SSM, and SSM, and the module by the generated Tx part process. Recording a message to be transmitted by each process created in the process and creating a process queue used as a transmission buffer of the recorded message, and predefined by the generated Tx partial process Creating a Tx message queue having a key value and delivering a predetermined message written to the generated Rx partial process, and performing a process process on the process queue and the Tx message queue by IPC ( Inter Process Communication) connects and transmits a message recorded in the Tx message queue to the Tx message queue through the IPC connection to the Tx message queue. Recording and if the Rx partial process checks whether or not the Tx message queue is generated, and if the creation of the Tx message queue is confirmed, a loop for reading a message recorded in the Tx message queue is repeatedly performed. We propose a module integration method through the process.

Further, in the proposal of the present invention, the Tx partial process reads the process queue, checks whether a message transmitted from a predetermined process generated in the module is written, and if it is confirmed that it is recorded. The process of transmitting the message recorded in the process queue to the Tx message queue is further added.

On the other hand, prior to the detailed description of the present invention, a summary of the implementation method for achieving the above object and technical problem of the present invention.

First, the present invention does not use a structure of a conventional intelligent network switching system for transferring a message between modules through a socket communication based on TCP / IP, but uses a message transmission structure through an inter process communication (IPC) method between processes.

This message transmission structure is proposed, firstly, so as not to change the message format delivered in the conventional manner at all, and secondly, to not change the interface of processes that deliver or receive the message. And third, to reduce the overhead of creating TCP / IP-based socket communications. Therefore, it is possible to run a service exchanger module (SSM), a service control module (SCM), and an intelligent information system (IP) module in one machine, thereby providing a basic platform for providing a small capacity intelligent network exchange system. Will be provided.

First, with reference to the accompanying Figure 4 will be described the internal architecture of the intelligent network switching system according to the present invention. 4 is a diagram illustrating a basic structure of message transmission using IPC on one machine.

In FIG. 4, the connection between the service switch module (SSM) 410, the service control module (SCM) 420, and the intelligent information providing system (IP) module 430 is different from the socket connection of the conventional intelligent network switching system shown in FIG. 1. It is replaced by an IPC structure. This is a structure for transmitting messages between modules in one machine. Messages are transmitted between the Tx part process of one module and the Rx part process of another module.

The message transfer mechanism between modules shown in FIG. 4 is shown in FIG. FIG. 5 is a diagram illustrating a message transfer mechanism between modules through IPC in an intelligent network switching system according to the present invention, wherein a process generated in a given module transmits a message with another module through an IPC structure according to a need of a service or function It is a figure which shows the state to make.

Referring to FIG. 5, a message transmission state between modules of an intelligent network switching system according to the present invention is described. A predetermined process 512 generated in one module requires a predetermined function or service to communicate with a service exchange module (SSM) 410 ( Communication is required. At this time, the process 512 creates a predetermined message queue. The process 512 is a Tx partial process, which is created independently in the modules.

The generated message queue 514 records a message to be transmitted by each process created in the module by the generated Tx partial process and is used as a transmission buffer of the recorded message. Function as). In addition, a Tx message queue 516 having a key value predefined by the generated Tx partial process and delivering the recorded message queue to a predetermined Rx partial process is generated. This is a message in which the message transmitted to the process queue 514 is transmitted and stored through IPC, and has a structure in which Tx and Rx routines can simultaneously access. The message recorded in the Tx message queue 516 is transmitted to the Rx partial process implemented in the counterpart module to transmit the message.

Its operation is that if a transmission message is sent to a Tx Part process 512 from any process in the sending module, the Tx Part process 512 calls the corresponding Routine, and the called routine periodically The transmission message is temporarily recorded in the process queue 514, and the recorded transmission message is transmitted to and recorded in the Tx message queue 516 through the IPC connection. Then, the recorded message is read and transmitted to the Rx part process 518 of the counterpart module. At this time, the Rx partial process 518 determines whether the Tx message queue 516 is generated, analyzes the message recorded in the Tx message queue 516, and transmits the recorded message to the corresponding process according to the analysis result. do.

That is, the present invention shown in FIG. 5 generates a Tx message queue capable of exchanging messages between a Tx partial process of one module and an Rx partial process of another module, and a process queue for receiving a message transmitted from each process. It consists of a part that creates a queue, and consists of a Tx part process that periodically reads messages and sends them to the message queue, and a Tx part process that periodically reads messages written from the message queue and sends them to the appropriate process. will be. The message transmission between the process queue and the Tx message queue is performed through IPC, and the processes are independently generated and operated.

FIG. 6 is a diagram illustrating an algorithm for message transmission between modules in an intelligent network switching system having the structures shown in FIGS. 4 and 5, and illustrates an inter-module message transmission algorithm through IPC in an intelligent network switching system according to the present invention. Drawing.

Referring to FIG. 6, the generated Tx partial process 512 starts a message Tx routine for message transmission. At the same time, the message Rx routine is called to start the operation. Then, in step 612, the Tx partial process 512 creates an Rx routine and a Tx message queue 516 for message transmission. The generated Tx message queue 516 has a predefined key value, and the Tx message queue 516 is used to deliver a message to the Rx part process of the counterpart module. Whether to create the Tx message queue 516 is made through an IPC connection. In step 622, the Rx partial process confirms the fact. In operation 614, a process queue 514 is used to record a message to be transmitted by each process created in the module by the Tx partial process 512 and to be used as a transmission buffer of the recorded message. do. The generated process queue 514 operates as a buffer for message transmission of different processes in step 616, reads a message from the process queue 514, and passes the message to the Tx message queue 516 through IPC. This operation is repeated. At the same time, in step 624, the Rx partial process 518 confirming that the Tx message queue 516 is generated, reads a message from the Tx message queue 516 and receives a message, which is repeatedly performed. That is, the Rx partial process 518 checks the existence of the Tx message queue generated by the Tx partial process, and if it is determined to be generated, the Rx partial process 518 performs the operation of step 624 to read a message from the Tx message queue. Will be. The Tx part process also periodically checks whether each process has sent a message through the process queue, and if confirmed, continuously transmits the message recorded in the process queue to the Rx message queue through IPC.

Therefore, the Tx partial process and the Rx partial process exchange messages through one message queue.

In conclusion, in the implementation of the intelligent network switching system according to the present invention, after generating independent Rx part and Tx part processes in IP, SSM, and SSM, each process generated in the module is transmitted by the generated Tx part process. A process queue used to record a message to be written and used as a transmission buffer of the recorded message, and has a predefined key value and is written to the generated Rx partial process. Create a Tx message queue that delivers a message. The Tx message is transmitted by interprocess communication (IPC) connection between the process queue and the Tx message queue to transmit the message recorded in the process queue to the Tx message queue through the IPC connection. When writing to the queue, the Rx partial process checks whether the Tx message queue is created and then repeats a loop for reading the message written to the Tx message queue.
