Description

Operation status management method from information providing system to service controller

The present invention relates to an operation state management method of an intelligent network application protocol (INAP), and in particular, a next-generation intelligent network information providing system (AIN IP) sends an operation processing request to a service controller (SCP), the service controller (SCP) for the request It relates to a state management method for an operation for receiving a result of the processing.

In the existing intelligent network, the information providing system is used to provide intelligent network services to service users by implementing a simple announcement broadcasting and DTMF collection function in a service switching point (SSP) without using an information providing system (IP). There was no need for an application protocol between the IP and the service controller (SCP).

However, next-generation intelligent network service should be able to provide various special resources such as voice guidance, dual tone multi frequency (DTMF) collection, voice recognition, speech synthesis, voice recording, fax processing, etc. Since it is expensive to develop and it is difficult to easily change new resources for the developed network resources, it is necessary to develop an information providing system (IP) for providing the various special resources and connect them to the network. I tried to solve the problem.

Intelligent Network Application Protocol (INAP), which is implemented in the IP for communication between the IP and the next-generation intelligent network elements in the next-generation intelligent network, operates on an operation for providing an application service between the IP and the SCP. It is necessary to manage the statuses for these graded operation operations.

Among the contents of the operation status of each grade, the contents of the initial intelligent network SSP are indicated in the domestic standard, but this is the contents of the operation of the operation in the initial intelligent network SSP. As a result, an operation state management method is required separately.

Therefore, in the present invention, when a service is requested by an information providing system (IP) among operations in a next generation intelligent network service, an operation state management diagram of an operation is prepared in the intelligent network application protocol (IP INAP) to process the requested service call. The present invention relates to a method for managing a success or error state of an execution and a result from the start of an operation for an operation requiring an intelligent network application protocol (IP INAP) to process a service control network application protocol (SCP INAP).

The state management method for the operation provided by the present invention idles the operation state of the operation in the intelligent network application protocol when a service for a special resource is requested by the information providing system (IP) and the information providing system requests the operation by the service controller. An operation state management diagram indicating a state, an operation pending state, an operation execution state, and a rejection pending state is prepared, and the start, performance, and result of the requested operation are managed by the operation state indicated in the operation state management diagram. It is done.

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

FIG. 1 is a configuration diagram of a next generation intelligent network intelligent information system. Referring to FIG. 1, the next generation intelligent network intelligent information system (AIN IP) 110 is connected to a disk array 112 in which a plurality of disks are arranged to provide operator information. An intelligent network service controller (AIN SCP) 120 and an intelligent network by a specialized resource main processor (SRMP) 111 that manages and performs its operator matching and operation functions, and a common line signaling network 130. A Specialized Resources Switch (SRS) 114 connected to the AIN SSP 140 to perform protocol and service call processing, and a Special Resource Unit (SRU) to perform processing for special resource information. Specialized resource unit (115), each of the components (111, 114, 115) are connected by a LAN Route Switch (113).

At this time, the intelligent network application protocol (IP INAP) of the present invention is mounted in the protocol processing unit of the special resource exchange (SRS) 114, the configuration of the intelligent network application protocol block is shown in FIG.

Referring to FIG. 2, the intelligent network application protocol block (INAP) 220 communicates with a specialized service control subsystem (SSCS) 210 by an AP-primitive, and performs component processing (CHA: Component). Communication by the TC-primitive with the TCAP (Transaction Capabilities Application Part) 230 composed of HAndler, Dialogue HAndler (DHA) and Transaction HAndler (THA). Performing operational state management, particularly in the shaded areas.

In addition, a single association control management (SACM) module, a single association operation control (SAOC) module, a single association dialog control (SADC) module, A protocol message matching (PMM) module is included in the intelligent network application protocol block (IANP) 220.

At this time, the intelligent network application protocol divides the operation between IP and SCP into four classes, and fails or succeeds after performing the operation, and transmits the result to both classes, which is called 'class 1', and fails only when the operation fails. The case of transmitting a result is called "class 2", and the case of transmitting a success result only if it succeeds after performing an operation is called "class 3". In addition, a case in which failure or success and neither result is transmitted after performing the operation is referred to as 'grade 4'.

3 is a process flow diagram for a class 2 operation according to an embodiment of the present invention, the process for managing the status of the operation in the intelligent network application protocol (IP INAP) to perform the Assist Request Instruction (ARI) The flow is shown, in the drawing "!" Means to send a message, "?" Means to receive a message, a lowercase message is a message processed inside the IP system, and an uppercase letter indicates a message exchanged with a partner node SCP.

Referring to FIG. 3, a state of performing an operation for performing the example may be an idle state 301, an operation pending state 302, an operation performing state 303, and a rejection pending 304 state. In the idle state 301, sending a TC_Iinvoke request (INVr) component, which means a request to perform a class 2 operation, to the SCP 31 becomes an operation pending state 302, and in the operation pending state 302, a new logical communication. The TC_Begin request (BEGr), which indicates the start of the login dialog, is transmitted 32 and the operation execution state 303 is reached. In the operation execution state 303, the SCP is processing the corresponding operation, and if no message is transmitted to the IP for a predetermined time required for performing the operation, the question and answer processing unit (TCAP: Transaction Capabilities) at the bottom of the IP INAP is performed. Application Protocol) receives the TC_L_Cancel indication (l_cani) 33 and enters the idle state 301. This means that the operation was successful without errors. However, if the TC_U_Errror indication (U_ERRi) 33 is received before l_cani occurs, the dialog is released and the call-related resource is released by notifying the upper PMM of the dialog release.

In the operation execution state 303, when the TC_U_Reject indication (U_REJi), the TC_R_Reject indication (R_REJi), or the TC_L_Reject indication (l_reji) are received 34, the result is a rejection pending state 304. This is the case when the operation requested to be performed is rejected by SCP INAP (U_REJ), rejected by SCP TCAP (R_REJ), or U_ERR message sent by SCP INAP is rejected by IP TCAP (L_REJ). In addition, in the rejected pending state 304, the above-mentioned Reject messages operate differently depending on which dialog message is loaded. That is, after receiving the TC_Continue indication (CONi) indicating the dialogue continue, the INAP receives the message. Sends a dial_rel message notifying the release of the dialog to the higher PMM and sending a TC_U_Abort request (U_ABOr) message to the SCP requesting that the dialog be terminated (35), but with a TC_End indication (ENDi) requesting that the dialog be terminated. If so, only the dial_rel message is transmitted to the PMM and then idle (301).

FIG. 4 is a flowchart illustrating a grade 4 operation according to an embodiment of the present invention, and shows an embodiment of a specialized resource report (SRR).

In this case, the operation state of the operation is the same as that of FIG. 3, and when the TC_Iinvoke request (INVr) component, which means the request for performing the class 4 operation, is idle (41) in the idle state 301, the operation pending state 302, and the operation pending state 302 transmits 42 a CONr or ENDr message requesting the continuation or termination of the dialog. In other words, after the operation is sent to SCP, if the IP is disconnected from the SSP, it is sent to ENDr, otherwise it is sent to CONr.

Then, in the operation execution state 303, SCP proceeds with the operation processing, and after receiving a predetermined time required for performing the operation, when receiving 43 l_cani from the TCAP (43) becomes an idle state 301, l_cani occurs Receiving U_REJi or R_REJi before 44 results in a reject pending state 304. This means that the operation requested to be performed is rejected by SCP INAP (U_REJ) or rejected by SCP TCAP (R_REJ), and l_reji does not occur because SCP does not send the result after performing the operation.

When the reject message is received, the rejected pending state 304 is transmitted, and the U_ABOr message is transmitted 45 together with the dial_rel or dial_rel message as described with reference to FIG.

In the method of the present invention, when the IP requests the SCP to perform operations of class 2 and 4 operations for special resource call processing, it transmits the operation processing request to the counterpart node SCP and operates according to the preset state diagram. By managing the execution and processing results, it is possible to effectively manage operations for special resource services of the next generation intelligent network information system.
