Description

Method and apparatus for processing insert subscriber data considering working state of multi-home location register and request for changing duplicate information {working state and multi-HLR and duplicate information change request}

The present invention relates to the operation of a multi-home location register in a mobile communication system, and more particularly, to a method and apparatus for transmitting subscriber information in a multi-home location register in which a database is synchronized with each other.

With the recent rapid development of electronic engineering and communication engineering, mobile communication terminals have various functions and mobile communication systems also provide various services. That is, with the rapid development of wireless communication and data processing technology, people can use not only voice call service but also internet access, video communication and video message transmission service using a mobile communication terminal. Also, due to the rapid spread of mobile communication terminals, mobile communication has become an essential means of communication in modern life, such as a considerable amount of communication occurring in human relationships through mobile communication terminals.

The mobile communication system providing the mobile communication service includes a mobile switching center (MSC), a home location register (HLR), a base station controller (BSC, RNC), a base station (BTS, Node B), and a mobile communication terminal (MS). . A mobile switch is a core network element of a mobile communication network. It controls voice calls and various additional services, establishes a call path, and provides a connection function with various other devices and external networks. That is, the mobile switch is a switch that provides a circuit switching service and a call channel switching function to a mobile subscriber.

Here, the home location register plays an important role in managing and ensuring mobility of mobile communication terminals in association with the exchange. That is, the home location register always grasps the current location information of the mobile communication terminals through the location registration procedure. Through this, the mobile switch provides the location information of the mobile communication terminal to the home location register, and, if necessary, receives the location information of the terminal from the home location register. To this end, the mobile switch is provided with a visitor location register to temporarily store and use the location information and subscriber information of the mobile communication terminal under jurisdiction.

Therefore, when the information on the mobile communication subscriber is changed in the customer information management server, the changed information is transmitted to the home location register and reflected in the subscriber information stored in the home location register. Furthermore, when the subscriber information stored in the home location register is changed, the changed information is transmitted to the mobile exchange which is in charge of the mobile communication terminal of the subscriber to reflect the changed subscriber information in the visitor location register provided in the exchange.

Since the home location register stores important information of the subscriber, it is operated in a redundant or multiplexed structure to maintain the operation state even in case of emergency. This multiplexing architecture works because two independent systems synchronize their databases.

However, if one of the multi-home location register system has hardware or software failures and errors, the redundant and multiplexed structures are released and switched to a single operation state. In this single operation state, the ability to synchronize the database on both systems is turned off. If a failure occurs when the database A is normally changed on system A and attempts to synchronize to system B, the subscriber information between the two systems is inconsistent. A state of moment occurs.

As such, a problem that may arise when subscriber information exists in an inconsistent state is a request for changing a real-time service of an intelligent network prepaid subscriber. At present, home location register system transmits subscriber information to exchange only when DB change occurs in order to reduce unnecessary network load depending on the equipment used. That is, the DB does not change when a duplicate service change request is made, and thus the subscriber information is not transmitted to the exchange. In this situation, if the intelligent network prepaid subscriber charges the prepaid fee while the balance is exhausted, the system is not synchronized due to the system problem when the HLR A system attempts to synchronize with the HLR B system after the change is normally reflected by the DB change request. Suppose, after that, when the DB change request is made again due to the balance exhausted, the B system does not transmit the subscriber's information to the exchange because it is already stored in the DB with the balance exhausted. This causes a problem that does not guarantee the real-time services of the intelligent subscribers.

In addition, if the call stop service is not normally applied to the terminal due to a data transmission error at the wireless end, when the subscriber attempts to make a call, the subscriber stops to request the call stop service from the intelligent network server to the HLR system. There is a problem that the change in the DB state does not occur by the real-time service of the subscriber can not be guaranteed.

Accordingly, the present invention has been made to solve such a problem, and it is appropriate to check the synchronization state and operation state of the HLR during the subscriber information transmission process according to the change of the information of the home location register in the multiple home location register operating system. It is an object of the present invention to provide a method and apparatus for easily performing subscriber information transmission processing.

Other objects and advantages of the invention will be described below and will be appreciated by the practice of the invention. Further, objects and advantages of the present invention can be realized by the means and the combination shown in the appended claims.

In order to achieve the above object, the subscriber information transmission processing method in consideration of the operation status of the multi-home location register according to the present invention and the request for changing duplicate information, in a mobile communication system operating a multi-home location register in which the database is synchronized with each other A method for transmitting subscriber information according to a change in information of a home location register, the method comprising: (a) receiving a change request from outside of a home location register and changing the corresponding information in a database; (b) checking the operation state of the multi-home location register and transmitting the subscriber information to the switch of the subscriber corresponding to the changed information when the single home location register is in operation; And (c) when the multi-home location register is in operation in step (b), confirming whether or not a substantial change of information in the database has been made according to the information change processing, and transmitting and processing subscriber information according to the change; It includes.

According to another aspect of the present invention, a subscriber information transmission processing apparatus according to a change of information of a home location register in a mobile communication system operating multiple home location registers whose databases are synchronized with each other, subscriber information and subscriber location registration information are stored, A database in which information is synchronized with other home location registers linked with each other; Information changing means for receiving an information change request from the outside and modifying the corresponding information in the database; Operation state checking means for checking an operation state of the multi-home location register and determining whether the single home location register is in operation or normal multi-home location register in operation due to a failure and an error; DB change checking means for determining whether or not substantial information change has been made in the database according to the information change processing; And when the information change processing occurs in the information changing means, referring to the operation state checking means, and when it is determined that the single home location register is in operation, transmitting the subscriber information to the subscriber exchange corresponding to the changed information, In the case where it is determined that the home location register is operating, subscriber information transmission means for transmitting and processing subscriber information according to whether or not the actual information is changed through the DB change checking means. Provided is a subscriber information transmission processing apparatus.

According to the present invention, even when only a single home location register is operated due to an error or a failure in a system that operates multiple home location registers, or when a duplicate service change request of an intelligent network prepaid subscriber occurs due to a packet transmission error of a wireless end, the intelligent network It can reflect the real-time service request of the subscriber, which not only guarantees the service of the subscriber in real time, but also has the effect of reducing the VOC of the customer and increasing the profitability of the company by performing accurate billing processing in real time.

In addition, when a general multi-home location register operation is normally performed, it is possible to reduce the load of the network system by comparing the state with the previous DB when the duplicate information change request is not performed and not performing subscriber information transmission processing in the same case.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, terms or words used in the specification and claims should not be construed as having a conventional or dictionary meaning, and the inventors should properly explain the concept of terms in order to best explain their own invention. Based on the principle that can be defined, it should be interpreted as meaning and concept corresponding to the technical idea of the present invention. Therefore, the embodiments described in the specification and the drawings shown in the drawings are only the most preferred embodiment of the present invention and do not represent all of the technical idea of the present invention, various modifications that can be replaced at the time of the present application It should be understood that there may be equivalents and variations.

1 is a diagram illustrating a part of a mobile communication system in which a subscriber information transmission processing method is implemented in consideration of an operation state of a multi-home location register and a request for changing duplicate information according to an embodiment of the present invention.

As shown in FIG. 1, a mobile communication system in which the present invention is implemented includes an external information change request node 200 consisting of a customer information management server 210 and an intelligent network 220, and a plurality of home location registers operated in synchronization with each other. Is composed of a multi-home location register 100, and a plurality of exchanges 300 connected to the multi-home location register (100).

The external information change request node 200 is composed of a customer information management server 210 and an intelligent network 220, and requests the information change request such as subscriber information change and additional service information change to the multi-home location register 100. It plays a role. The customer information management server 210 is a device for registering and managing customer information for mobile communication service subscribers. The customer information management server 210 is called a 'WISE (Wireless Information Service Environment)'. In addition, the customer information management server 210 registers and manages customer information such as inserting, changing, or deleting information according to a request of a customer or a subscriber, and adds subscribers such as when a subscriber subscribes to a new additional service. Service information is also registered and managed. In addition, the customer information management server 210 transfers the stored and managed customer information to the multi-home location register to be described later to reflect the changed information stored in the home location register.

The intelligent network 220 is a device for performing a service such as charging a prepaid fee and managing a balance of an intelligent network prepaid subscriber. The intelligent network 220 checks the rate of the prepaid subscriber in real time and notifies the home location register when the balance is exhausted, so that the information request is changed to the DB due to insufficient prepaid service balance. In addition, it also plays a role in reflecting this to the home location register when the balance is filled in the DB.

The multi-home location register 100 registers location information of mobile communication terminals, and manages mobility information of terminals. In addition, the multi-home location register 100 stores and manages the information of the location registered mobile communication subscribers in a DB, and also stores and manages additional service information. In addition, by receiving the information change request from the customer information management server 210 or the intelligent network 220 serves to change and apply the information corresponding to the DB. Furthermore, when the information of the DB is changed in response to the information change request, the multi-home location register 100 performs a subscriber information transmission (ISD) process of transmitting the corresponding information to the subscriber's switch corresponding to the changed information. Of course, the multi-home location register 100 also serves to register the location information of the moved terminal according to the location registration process when the mobile communication terminal moves.

In addition, the multi-home location register 100 is provided with a plurality of home location registers, and configured to synchronize the information of the database with each other, even if any one of the home location registers failure and error is synchronized with the remaining home location register Can be operated normally. In addition, when the subscriber 300 transmits the subscriber information to the switch 300, the operation state of the multi-home location register 100 and the request for changing duplicate information are performed. A more detailed description thereof will be described below with reference to FIG. 2.

The exchanges 300 perform mobile communication exchange processing services of mobile communication terminals. That is, incoming and outgoing exchange processing of wirelessly connected mobile communication terminals is performed. The exchange 310, 320, 330 includes visitor location registers 311, 321, 331, and stores and manages subscriber information (including additional service information) of a mobile communication terminal that is currently in charge. The information stored in the visitor location registers 311, 321, and 331 is received from the multi-home location register 100 and stored. When the mobile communication terminal roaming or handing off moves to another exchange, the corresponding subscriber of the visitor location register The information can be deleted. That is, only the subscriber information of the mobile communication terminal entering the jurisdiction of the exchange at the time of location registration is provided and managed from the home location register 100.

2 is a diagram illustrating a configuration of a subscriber information transmission processing apparatus considering an operation state of a multi-home location register and a request for changing duplicate information according to an embodiment of the present invention.

First, the subscriber information transmission processing apparatus 100 according to the present invention includes a configuration of a general multi-home location register, and performs a function of a general multi-home location register. In addition, referring to FIG. 2, the subscriber information transmission processing apparatus 100 according to the present invention includes an information change module 110, an operation state checking module 120, a DB change checking module 130, and a subscriber information transmitting module ( 140, database 150, and the like.

The database 150 stores and manages database-related information about mobility of the home location register, subscriber information and additional service information. The information stored and managed in the database 150 is synchronized to a database of other home location registers linked to each other immediately after the change, and the change is reflected. Through this operation, even if the operation of one home location register is stopped, another linked home location register operates normally, so that it is possible to perform a normal home location register function using a synchronized database.

The information change module 110 is responsible for reflecting the change processing to the information corresponding to the database 150 in response to an external information change request. The information change module 110 includes a change request receiving unit 112, a DB change applying unit 114, and the like.

The change request receiver 112 serves to receive an information change request from an external node. The change request receiver 112 receives an information change request from the customer information management server 210 and the intelligent network 220. For example, when the customer information in the customer information management server 210 changes the subscriber information or changes the additional service, the change request receiver 112 changes the request information to reflect the changed information in the home location register. Will be received. As another example, when the information change occurs according to the real-time service change request of the prepaid subscriber, such as charging the intelligent network prepaid rate in the intelligent network 220 or the prepaid rate is exhausted, the change request receiver 112 also requests the information change. Will be received.

The DB change application unit 114 performs a role of retrieving the corresponding information from the DB 150 and processing the changed request information to apply to the DB as a change request is received by the change request receiver 112. do. At this time, if the multi-home location register is normally synchronized and in operation, the changed information applied to the DB 150 is immediately applied to the DB of another home location register. Of course, when the multi-home location register is not normally synchronized due to a failure and an error, and operates in a single mode, the changed information cannot be applied to the DB of another home location register.

The operation state checking module 120 checks whether the multi-home location register is operating normally. The operation state checking module 120 includes an operation state checking unit 122, an operation state determining unit 124, and the like.

The operation state checking unit 122 checks the operation state of the plurality of home location registers provided in the multi-home location register. That is, by checking the status of the DB provided in each home location register or each home location register, it is checked whether it is in normal operation or abnormal operation or stop operation due to a failure or error.

The operation state determination unit 124 checks whether all of the home location registers of the multi-home location register are operating normally and are operating in synchronization with each other. The device operates abnormally and stops, and it is not synchronized and serves as a single home location register. When a plurality of home location registers are not synchronized due to a failure or the like, they are determined to be in a single operation state or a state in which a multiplexed structure is released. On the other hand, if all of the multiple home location registers operate normally and are synchronized, it is determined to be in a multi-operation state or a multi-duplex structure maintenance state.

The DB change check module 130 checks whether the actual change processing is performed by comparing the DB state before the information change and the DB state after the information change when the DB information is changed and processed according to the information change request. The DB change check module 130 includes a DB state check unit 132, a DB state compare unit 134, a change state determiner 136, and the like.

The DB status checking unit 132 checks the DB status before the information change processing and the DB status after the change processing according to the DB information change request. Although the information is substantially changed and applied to most DBs according to the information change process, in the case of a duplicate service change, the change process is performed, but the information or state in the actual DB may not be changed.

The DB state comparing unit 134 compares the DB state and information before and after the change confirmed by the DB state checking unit 132. This is to check whether information change in the actual DB has been made.

The change determination unit 136 determines whether or not the actual DB change is made according to the comparison result in the DB state comparison unit 134. At this time, if the DB state before and after the comparison result in the DB state comparison unit 134 is the same, it is determined that no substantial change is made, and if the DB state before and after the change is determined that the actual change is made. do.

The subscriber information transmission module 140 performs subscriber information transmission processing according to the changed information to the exchange during the information change processing in consideration of the operation state of the multi-home location register and whether or not the actual DB changes. The subscriber information transmission module 140 includes an information transmission processor 142, an operation status checker 144, a change status checker 146, and the like.

When the information transmission processor 142 needs to proceed with the subscriber information transmission process, the information transmission processor 142 performs a role of transmitting the subscriber information to the changed information to the subscriber's exchange corresponding to the changed information. At this time, the subscriber information transmission process uses an Insert Subscriber Data (ISD) message.

The operation state check unit 144 checks the operation state of the multi-home location register determined by the operation state check module 120, and when the synchronization is released in a single operation state through the information transmission processor 142. It plays a role of proceeding subscriber information transmission processing. At this time, the subscriber information transmission process is performed during the change process regardless of the actual DB change. On the other hand, the operation state check module 120 checks the operating state of the multi-home location register, in the case of the normal multi-operation state being synchronized, depending on whether the actual DB change in the change state check unit 146 to be described later The subscriber information transmission process is performed through the information transmission processor 142.

The change state check unit 146 is a normal multi-operation state being synchronized by the operation state check unit 144, according to whether or not the actual change of the DB determined by the DB change check module 130 has been made; The information transmission processing unit 142 plays a role of determining whether to perform subscriber information transmission processing. That is, in the case where the actual DB change is made as a result of the determination by the DB change checking module 130, the subscriber information transmission process is performed through the information transmission processing unit 142, and the actual DB change is not made as a result of the determination. Cancels the subscriber information transmission process so that the subscriber information transmission process is not performed even when the change request is made. This can reduce the system load that may be caused by transmitting meaningless information or duplicated information to subscriber information.

3 is a flowchart illustrating a procedure of a subscriber information transmission processing method considering an operation state of a multi-home location register and a request for changing duplicate information according to an embodiment of the present invention.

Referring to FIG. 3, first, a procedure of receiving an information change request from the outside is performed in the home location register. At this time, the customer information management server or the intelligent network, etc. receives the information change request according to the subscriber information change, additional service change, real-time service change, etc. (S1).

As described above, in response to the request for information change, a process of changing the corresponding information of the DB provided in the home location register and reflecting the change is performed. At this time, the corresponding information is changed in the DB, but the actual information content before and after the change may be changed or may be in the same state. This is because the same information may be processed in the DB due to the change of duplicate information, etc. (S2).

Next, a procedure for checking the operation status of the multi-home location register is performed before proceeding to the subscriber information transmission process to the subscriber of the changed information. The operation state or operation state of the multi-home location register checks whether or not a plurality of home location registers are in a single operation state which is operated only as a single home location register without synchronization due to a failure or an error (S3).

In this case, when it is determined that the single operation state is not synchronized with other home location registers, the subscriber information transmission process is immediately performed to the exchange of the subscriber corresponding to the changed information according to the information change processing. That is, the subscriber information transmission process is performed regardless of whether or not the actual information of the DB is changed. Through this, there was a substantial change of information, but the information was not reflected in the DB of the home location register due to synchronization problems. Ensure guaranteed and accurate billing (S4)

On the other hand, if it is determined that the normal multi-operation state, not the single operation state, all the home location registers are synchronized and the information is in a consistent state, so that the DB change state is checked before the subscriber information transmission process. That is, it is checked whether the information state of the previous DB is the same by comparing the DB state and information before and after the information change processing to the DB (S5).

Here, in the same state as the previous DB information after the information change processing, the subscriber information change processing is canceled and the subscriber information transmission processing is not performed. This is to reduce the load by not performing unnecessary subscriber information transmission processing since no actual information has been changed. (S6)

On the other hand, after checking the DB change state, if the process is different from the previous DB information after the information change process to proceed to the subscriber information transmission process. That is, since the actual information change is made, the subscriber information transmission process of transmitting the change information to the switch of the subscriber corresponding to the changed content is performed.

Hereinafter, an embodiment of the present invention will be described on the assumption that multiple home location registers are synchronized and are normally operated, and are not synchronized due to a failure and are operated as a single home location register.

4 is a diagram illustrating a procedure performed when a multi-home location register is synchronized and in a normal operation state in a subscriber information transmission processing method according to an embodiment of the present invention.

First, a procedure for requesting information change from a WISE or an intelligent network to multiple home location registers is performed.

In the multi-home location register, a process of applying information change processing according to a change request to a DB is performed.

After the information change processing, normal synchronization processing for synchronizing the changed contents to another home location register is performed. This is because it is assumed that the synchronization status of the normal multi-home location register.

Next, a procedure for determining an operation state is performed, and a procedure for confirming a normal multiple operation state in which synchronization is performed is performed as described above. (14, 15)

As the normal multi-operation state is confirmed, a procedure for determining whether or not the actual DB change has been made is carried out.

As a result of the determination of the actual DB change status, it is checked whether the information is the same as the information of the previous DB, and if the actual information change is made, the procedure of performing the subscriber information transmission process (ISD) for transmitting the changed information to the corresponding exchange is performed. 17,18)

On the other hand, if it is determined that the actual DB has not been changed, the subscriber information transmission processing is canceled so that no further process is performed.

As described above, according to an embodiment of the present invention, when multiple home location registers are synchronized and normally operated, the subscriber information transmission process is performed only when the actual DB is changed, otherwise, the actual DB is not changed. If not, the subscriber information transmission process can be omitted, thereby reducing the load caused by unnecessary transmission process.

FIG. 5 is a diagram illustrating a procedure performed when synchronization of multiple home location registers is canceled and operated as an abnormal single home location register in a subscriber information transmission processing method according to an embodiment of the present invention.

First, a procedure of receiving an information change request from a WISE or an intelligent network to multiple home location registers is performed.

In the multi-home location register, a process of applying information change processing according to a change request to a DB is performed.

After the information change processing, the synchronization process fails to synchronize the changed contents to other home location registers and operates only as a single home location register. This is because it is assumed that the synchronization failure state of the abnormal multi-home location register.

Next, a procedure for determining an operation state is performed, and a procedure for confirming an abnormal single operation state in which synchronization is not performed as described above is carried out. (24, 25)

In this way, if the operation state of the multi-home location register is confirmed to be an abnormal state during a single operation, a procedure for performing subscriber information transmission (ISD) processing according to the changed information to the exchange regardless of whether the actual DB changes.

As such, according to another embodiment of the present invention, when the multi-home location register is operated only as a single home location register because of synchronization failure due to a failure or an error, the changed information immediately after the information is changed regardless of whether the actual DB is changed. By transmitting the subscriber information to the exchange, it is possible to guarantee the service of the subscriber in real time by preventing the information change omission and the like, it is possible to perform accurate billing.

The method of the present invention as described above may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form. Since this process can be easily implemented by those skilled in the art will not be described in more detail.

Although the present invention has been described above by means of limited embodiments and drawings, the present invention is not limited thereto and will be described below by the person skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of the claims.
