Method for data management of a home location register

The present invention relates to a data management method of a home location register (HLR), and more particularly, to store and manage service related data of a home location register in a shared memory, and to execute a command and a corresponding call processing and additional service. The present invention relates to a data management method in which a block that executes a link registers shared memory together so that data can be efficiently created, changed, or deleted without changing a process.

In general, a home location register applied to a mobile communication system is a device that registers subscriber information (mobile station information) for call processing.

In this case, the registration is a process in which the mobile station informs the base station of the mobile station so that the base station can efficiently determine the location of the mobile station when an incoming call is generated.

On the other hand, in the operation of the home location register (HLR), which is essential in the mobile communication network, the data handling process includes two data handling processes (TDBMDP), which writes to the database of the main computer through the MMC, and ODBM, which records through the graphical user interface. There is. The two processors serve to record subscriber information, additional service information, and station number information inputted through the operation and maintenance process in the subscriber database of the main computer.

As shown therein, the shared memory 100, which is a memory area shared by several processes at the same time, the MMC 200 which collects instructions from the operator and transmits them to the next process, and the MMC 200 from the MMC 200. TDBMD (300), which is a process of changing the corresponding data by analyzing the command, and MAP (400), which is a process of performing general call processing and additional service call processing.

The operation of the processes configured as described above is as follows.

First, the MAP 400 performing call processing with the TDBMD 300 executing a command shares service data stored in the shared memory 100, and when a change occurs in the data, the MAP 400 is real time. The changed data can be accessed.

Here, the service-related data are divided into announcement broadcasting code, trigger information and routing information of intelligent network service, digit collection information for each service, and feature code information for each service. Can be.

First, looking at the announcement code information, all announcements generated in the mobile network will send the announcement code from the home location register and the announcement will be sent from the exchange and the announcement by changing this code during operation. You can change the content of the broadcast.

Next, referring to the trigger information and routing information of the intelligent network service, trigger pointers are allocated for the intelligent network service. These triggers are managed by the home location register and must be changeable during operation. It also contains the routing information needed to connect to each server in order to receive these services, which are also managed by the home location register and must be changeable during operation.

Next, looking at the service-specific digit collection information, the necessary information for collecting this digit is managed in the home location register, the exchange refers to this information when collecting digits from the subscriber. And this information is service specific and should be changeable during operation.

Finally, looking at the feature code information for each service, the subscriber can change the service status by pressing the code of the desired service and sending it to the home location register. The feature codes are managed in the home location register and changed during operation. It should be possible.

4 is a flowchart illustrating a data management method of a home location register according to the present invention.

As shown in the drawing, when initial running is started in the TDBMD (ST11), generating a shared memory and writing default data to the created shared memory (ST12), and after writing the default data, the MAP runs In step ST13, the MAP connects and registers the shared memory (ST14), and if call processing and additional services are required after the connection registration of the shared memory is requested (ST15), it is checked whether a data change command is input by the TDBMD. Step ST16, updating the backup file by changing the data in the TDBMD if the check result data change command is present (ST17), and accessing the updated data from the shared memory in the MAP after the update (ST18). And processing the call processing and the supplementary service (ST19).

Referring to the home location register data management method made in this way is as follows.

First, the initial data for each function is set in the TDBMD 300 as a command processing block as a default value. At this time, if there is no backup file, the default value is set. If there is a backup file, the file data is written to the memory.

In this state, when the TDBMD 300 is executed in step ST11, the shared memory 100 is generated and updated with the data in step ST12.

The MAP 400 processes, which are the respective call processing and additional service processing blocks, are executed in step ST13, and attach the shared memory in step ST14 to use the data for call processing and additional service in step ST15.

Next, when the call processing and additional service is requested in step ST15, it is checked in step ST16 whether the TDBMD 300 data change command is input by the operator, and if there is a data change command, the TDBMD 300 in step ST17 corresponds to the corresponding data. Change That is, the changed TDBMD 300 data is updated in the corresponding backup file. In this case, in case the shared memory 100 is cleared, the changed data is backed up to a file. After that, the TDBMD 300 reads the data upon re-execution and reads the shared memory 100. ) And keep your changes.

Next, after updating the backup file in step ST17, in step ST18, the MAP 400, which is an application that accesses the updated data from the shared memory 100 in the MAP 400 and processes a related service in step ST19. It performs call processing and additional service with this changed data.

According to the present invention "data management method of the home location register" described above, it is possible to delete and change the data commonly used between the running processes without modification of the process, and also to change the software even at frequent data changes. There is no advantage in the stable operation of the system.
