Description

How to Change Subsystem of Signal Connection Control in Seven Signaling Network {Method of Transforming Subsystem of Signaling Connection Control Part in the No.7 Signaling Network}

The present invention relates to a method for changing a subsystem of a signal connection controller in a number seven signal network, and in particular, when a subsystem information is changed in a signaling connection control part (SCCP) of a number seven signal network, the generic name translation information is automatically generated. A method of changing a subsystem of an SCCP in a number seven signal network to be changed.

In general, the number seven signaling method is different from the conventional communication method in which the call path and the signal path are used together, and the signal path and the signal path are completely separated from each other so that a plurality of voice signals transmit and receive signal information through each independent channel. Common line signaling.

The network using the number seven signaling method is called a number seven signal network, and a signaling entity distinguished from the number seven signal network is called a signal point.

As shown in FIG. 1, the signal point is composed of a message transfer part (MTP), an SCCP, and an SCCP user part. The MTP is a function of delivering a signaling message to a destination. A signal data link function (level 1) that provides the characteristics of the data link and its access means, a signal link function (level 2) that carries signal messages between two signal points, and a signal message processing and network management function. Defined as a signal network function (level 3), the SCCP uses the MTP to provide the SCCP user part with a means of signal connection and signal data unit delivery, and the SCCP user part uses these functions.

In addition, the configuration of the destination address information in the number seven signal network is composed of an address indication and an address, as shown in FIG. In addition, as shown in FIG. 3, the address consists of a called party's signal point code, a subsystem number, and a global title, which can be omitted for each piece of information. The omission is recorded in the address indication.

Here, the signal point code is a number defined to be distinguished for each signal point in the number seven signal network. In the number seven signal network, the routine of the signal message is processed by using the corresponding signal point code that distinguishes between signal points. .

The subsystem number is a number defined by the SCCP and can be distinguished according to the function of the SCCP user part that goes up the SCCP. When the SCCP receives a signal message from the power station, the corresponding subsystem number is used. The signaling message will be distributed to the subsystem.

And, the global title translation information is composed of the called party signal point code and the subsystem number. In the number seven signal network, routing cannot be performed directly with the global title alone, and the general title translation information is received through the translation of the global title. Routing of the signaling message can be performed by translating to the side signal point code and the subsystem number.

The SCCP user unit may perform routing of a signaling message using the number seven signal network without knowing the physical configuration of the number seven signal network using the global name, and distribute the signal message according to the translation of the global name. It can also handle overload conditions.

On the other hand, in order to change the local and large subsystem information of the SCCP in the number seven signal network is necessary to delete and generating operations, the method of changing the local and large subsystem information is as follows.

First, referring to the flowchart of FIG. 4, a method of changing the local subsystem is described as follows.

First, in order to change the local subsystem information, the local subsystem related database is searched. At this time, the local subsystem related database is composed of the own local subsystem database and the global title translation information database.

The local subsystem database is a database for checking whether a corresponding local subsystem is defined, and as shown in FIG. 5, the local subsystem location, the local subsystem number, the local subsystem name, and the local subsystem Contains information about the location processor.

Also, the global title translation information database is a database for checking whether the global title translation information database has global title translation information (that is, information on signal point codes and subsystem numbers) corresponding to the corresponding local subsystem to be changed. 6, there is information on the global title translation location, the corresponding signal point code to be translated, the subsystem number and the global title to be translated.

Therefore, if the deletion of the own sub-system is requested (step S1), it checks the local sub-system database to check whether the corresponding sub-subsystem to be deleted is defined (step S2). If not defined, a failure is notified (step S3).

On the other hand, when the local station to be changed is defined, the global name translation information (that is, the information about the signal point code and the subsystem number) that is searched for the global title translation information database and translated into the local station to be deleted is If it is defined (step S4), in this case, if the general title translation information is defined, the general title translation information can be deleted first, and then the failure is notified (step S5).

When the global title translation information is not defined, the local station system is deleted and after the deletion is completed successfully (step S6), the local station system is newly generated with new information (step S7).

At this time, if the creation of the own sub-system is requested, this is checked (step S8) to search the local-subsystem database to determine whether the new information is defined, that is, whether the corresponding sub-subsystem to be generated is already defined. (Step S9) In this case, if the corresponding local subsystem to be generated is already defined, a failure is notified (step S10).

On the other hand, if the local self-subsystem to be created is not defined, after newly generating the local self-subsystem with new information (step S11), when the corresponding generation is completed, the general name translation information for the new local sub-system is generated. (Step S12).

Secondly, the method of changing the power subsystem is described as follows with reference to the flowchart of FIG. 7.

First, in order to change the power subsystem information, the power subsystem related database is searched. At this time, the power subsystem related database is composed of a SCCP signal point database, a power subsystem database, and a general name translation information database.

In addition, the SCCP signal point database is a database for checking whether a signal point of the corresponding sub-subsystem is to be defined. As shown in FIG. 8, the SCCP signal point database has information on a signal point position, a signal point code, and a signal point name. have.

In addition, the power subsystem database is a database for checking whether a corresponding power subsystem is defined, and as shown in FIG. 9, power subsystem position, power subsystem number, power subsystem name, and signal point code. Has information about

In addition, since the global title translation information database is the same as that shown in FIG. 6, the description thereof will be omitted.

Therefore, if the deletion of the power subsystem is requested, this is checked (step S21) to search the SCCP signal point database to determine whether the signal point where the corresponding power subsystem is located is defined (step S22), in which case the power to be deleted If the signal point where the subsystem is located is not defined, a failure is notified (step S23).

On the other hand, if the signal point in which the sub-subsystem to be deleted is located is defined, the sub-system database is searched to determine whether the sub-subsystem to be deleted is defined (step S24). If not, the failure is notified (step S25).

In addition, when the change-up sub-system is defined, the global-name translation information (that is, the information about the signal point code and the subsystem number) that is translated into the sub-system to be deleted by searching the global-name translation information database is defined. In step S26, if the general title translation information is defined, the failure is notified after the general title translation information can be deleted first (step S27).

If the global title translation information is not defined, after the deletion of the sub-system is successfully performed (step S28), the sub-system is newly created with the new information (step S29).

At this time, if generation of the power subsystem is required, it is checked (step S30) to search the SCCP signal point database to determine whether the signal point where the new power subsystem is located is defined (step S31), where the new If the signal point where the power subsystem is located is not defined, a failure is notified (step S32).

On the other hand, if the signal point where the new power subsystem is located is defined, the power station database is searched to check whether the power subsystem is already defined at the signal point (step S33). If the player subsystem is already defined, a failure is notified (step S34).

When the sub-system is not defined at the signal point, after newly generating the sub-system with new information (step S35), when the generation is completed, the global title translation information for the new sub-system is generated. (Step S36).

In the conventional number seven signal network as described above, when changing the information of the own station and the power subsystem of the SCCP, two operations necessarily delete and re-create the existing information. In addition, if the national and large subsystems to be changed are defined in the global title translation information, the local and large subsystem information can be changed only by first deleting the global name translation information of the local and large subsystems. It is necessary to create and redefine national and large subsystems, and then generate and redefine global title translation information.

As described above, when the subsystem information of the SCCP is changed in the conventional number seven signal network, two operations, namely, deletion and creation, are necessary, and when the subsystem information to be changed is defined in the global title translation information, all the global title translation information is included. After deleting, it is necessary to redefine the global title translation information with newly defined subsystem information, so that there is a problem in that the signal network management function is degraded and the network information cannot be changed quickly.

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a method for changing a subsystem of an SCCP in a number seven signal network to automatically change the global title translation information when the subsystem information is changed in the SCCP of the number seven signal network. , Its purpose is.

In addition, the present invention does not perform the existing information deletion and generation operation in the information change for the own station and the power subsystem in the SCCP of the number seven signal network, and requests the information before the change and after the change information for the own station and the power subsystem database database. By modifying the information, the existing information deleting and generating operation is reduced to one step of the changing operation, and even if the local and large subsystems to be changed are defined in the general name translation information, the existing information deleting and generating operation is not performed without performing the existing information deleting and generating operation. It is possible to automatically change the translation information of the name, to improve the management function of the signal network and to quickly cope with the change of the signal network, the purpose is to.

In the method of changing a subsystem of the SCCP in the number seven signal network according to an embodiment of the present invention for achieving the above object, after checking the subsystem change request in the SCCP of the number seven signal network, the information before the change is included in the subsystem information.

And a subsystem change process for modifying the information database.

Preferably, the sub-system change process includes: checking if the sub-subsystem change request is confirmed, checking the sub-subsystem database to determine whether the sub-subsystem information before the change is defined; After obtaining an index of a local subsystem database with respect to the local subsystem information before the change, confirming that the after-change information of the local subsystem is not defined in the local subsystem database; And modifying the local sub-system information before the change located in the index into the local sub-system information after the change.

Also preferably, the sub-system change process may include: after checking whether the local sub-system information before the change is defined in the global title translation information database, modifying the global title translation information with the local sub-system information after the change. Characterized in that further comprises.

Alternatively, if the subsystem change process confirms the request for changing the sub-system, the SCCP signal point database is searched to determine whether the signal point information where the sub-system sub-system is located before the change is defined, and the sub-system database is searched.

Preferably, the sub-system change process further includes the step of correcting the global title translation information with the sub-system information after the change after confirming that the sub-system information before the change is defined in the global title translation information database. Characterized in that the made up. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

A method of changing a subsystem of an SCCP in a number seven signal network according to an embodiment of the present invention will be described with reference to the flowchart of FIG. 10.

First, in order to change the own station and the player subsystem information, the own station and the player subsystem information database is searched.

At this time, the corresponding local subsystem information database has information about the local subsystem number, the local subsystem name, and the local subsystem location processor, as shown in FIG. It consists of system information and local and large subsystem information after change.

And, as shown in Fig. 12, the corresponding sub-system information database has information on the sub-system number, the sub-system name, and the sub-system position location signal point code, and the information corresponds to the own station and the grand power before the change, respectively. It consists of subsystem information and local and large subsystem information after change.

Accordingly, if a change of the own station and the power subsystem is requested, this is checked (step S41), and the search for the own station and the power subsystem information database is carried out so that the own and power subsystem information before the change is sent to the own station and the power subsystem information database. After checking whether it is defined (step S42), the local and large subsystem information database is modified using the local and large subsystem information after the change (step S43).

Then, after confirming whether the before-change own country and large country subsystem information is defined in the general name translation information database (step S44), the corresponding general name translation information database is corrected with the post-change local and large country subsystem information (step S44). Step S45).

As described above, in the method of changing the subsystem of the SCCP in the number seven signal network according to the embodiment of the present invention, the function of changing the local and large subsystems as described above is provided so that when the subsystem is changed in the SCCP of the number seven signal network. It is possible to modify the local and large subsystem information database by requesting the local and large subsystem information before the change and the local and large subsystem information after the change without performing the conventional method of deleting and generating information. It reduces the two steps of information deletion and generation operation, which is the method of the operation, to one step of the change operation. Allows you to automatically change the global title translation without performing two steps.

First, a process of changing a local subsystem in a subsystem change method of an SCCP in a number seven signal network according to an embodiment of the present invention will be described with reference to the flowchart of FIG. 13.

First, if local station subsystem change is requested, after checking it (step S51), the local station required for information change is searched by searching the local station subsystem database as shown in FIG. 11 to perform the local station information change function. It is checked whether or not the local subsystem information is defined in the local subsystem database with the subsystem number and the information in which the local subsystem is located, that is, whether the local subsystem information before the change is defined in the local subsystem database (step S52). .

If the own local subsystem information before the change is not defined in the own local subsystem database, a failure is notified (step S53), while the before own local subsystem information is defined in the local subsystem database. If there is, the index of the own local subsystem database with respect to the own local subsystem information before the change is obtained (step S54).

Then, it is checked whether information after the change of the own local subsystem is defined in the own local subsystem database, that is, whether new local subsystem information is defined in the own local subsystem database (step S55).

Thus, if the local station subsystem information after the change is defined in the own local subsystem database, a failure is notified (step S56), while the local station subsystem information after the change is not defined in the local station database. If not, modify the information of the local subsystem before the change located in the index of the local subsystem database before the change with the new information, that is, change the local subsystem information before the change located in the index of the local subsystem database to the local subsystem after the change. The information is corrected (step S57).

Thereafter, the global title translation information database is searched to check whether local subsystem information before the change is defined in the global title translation information database (step S58).

If the local sub-system information before the change is not defined in the global title translation information database, a failure is notified (step S59), while the local sub-system information before the change is transmitted to the global title translation information database. If defined, the global title translation information is corrected with the local subsystem information after the change (step S60).

Second, in the number seven signal network according to an embodiment of the present invention, a process of changing a sub-system in a sub-system change method of an SCCP will be described with reference to the flowchart of FIG. 14.

First, if a sub-system change is requested, after confirming it (step S71), in order to perform the sub-system information change function, as shown in FIG. 12, the sub-system subsystem number and the sub-system required for the information sub-system are changed. Verify that the signal point information is located and defined in the SCCP signal point database and the power subsystem database.

In other words, the SCCP signal point database is searched to determine whether signal point information (ie, pre-change sub-system information) in which the previous sub-system is located is defined in the SCCP signal point database (step S72), At this time, if the signal point information in which the corresponding sub-system is located before the change is not defined in the SCCP signal point database, a failure is notified (step S73).

On the other hand, if the signal point information where the previous sub-system is located is defined in the SCCP signal point database, the sub-system database is searched for the previous sub-system information is defined in the sub-system database. Is checked (step S74).

If the previous sub-system information before the change is not defined in the sub-system database, a failure is notified (step S75), while the previous sub-system information before the change is defined in the sub-system database. If there is, the index of the power subsystem database for the power subsystem information before the change is obtained (step S76).

Then, it is checked whether information after the change of the power subsystem is defined in the power subsystem database, that is, whether new power subsystem information is defined in the power subsystem database (step S77).

Therefore, if the sub-system information after the change is defined in the sub-system database, a failure is notified (step S78), while the sub-system information after the change is not defined in the sub-system database. If not, the pre-change power subsystem information located in the index of the pre-change power subsystem database is modified with new information, that is, the pre-change power subsystem information located in the index of the power subsystem database is changed. The information is corrected (step S79).

Then, the global title translation information database is searched to check whether the sub-system information before the change is defined in the global title translation information database (step S80).

If the previous sub-system information is not defined in the global title translation information database, a failure is notified (step S81), while the previous sub-system information before the change is transmitted to the global title translation information database. If defined, the global title translation information is corrected with the sub-system information after the change (step S82).

As described above, when the information on the own station and the sub-subsystem is changed in the SCCP of the number seven signal network according to the present invention, it is necessary to request the pre-change information and the post-change information without performing the existing information deletion and generation operation. By modifying the sub-system database, the existing information deletion and generation operation is reduced to a single step, and the existing information deletion and generation operation can be performed even if the host and the sub-system to be changed are defined in the global title translation information. It can automatically change the overall title translation information without performing, improving the management function of the signal network and responding to the change of the signal network quickly.
