System and Method for Processing Subscription of Subscriber Identity Module

The present invention relates to a system and method for processing a subscription of a SIM card subscriber, and more particularly, to increase the capacity of a subscriber to a home location register database in a mobile communication market of a distribution structure distributed after a bulk subscription such as a SIM card. A system and method for processing a subscription of a SIM card subscriber.

In order to provide a mobile communication service, subscriber's mobile identification information (MIN, MDN, ESN, etc.) and a mobile network service provider's code (MNC) are required. A device or program that stores information is generally called a Subscriber Identity Module (SIM).

Such a SIM in the form of a chip or a card that can be used in a mobile communication terminal is also used in a prepaid form. When a prepaid SIM card is purchased and inserted into a mobile communication terminal, the SIM can be opened and inserted to receive a mobile communication service.

On the other hand, the home location register generally uses a memory DB to maintain the performance of the system, pre-allocates as much space as the capacity of the subscriber that can be accommodated in this memory DB, and generates a field to provide a mobile communication service for each subscriber during the new subscription process. Fill in these fields with the required values.

In this case, the subscription information for the prepaid SIM card distributed to the retailer after being pre-subscribed occupies the subscriber information storage area of the home location register (HLR) at the time of subscription, and thus is not yet distributed after distribution to the retailer (Distributor). As the proportion of unsold SIM cards (hereafter referred to as 'Sleep SIM cards') increases, the actual system resources for service processing can be spared, but the expansion of the home location register is necessary due to unused Sleep SIM cards. Or, there is a problem that the cost of the operator is increased because the situation is to purchase additional licenses, the problem becomes more serious if there are more prepaid subscribers than postpaid subscribers.

Therefore, in the mobile communication market of prepaid subscribers, when the operator has a distribution structure in which a SIM card is pre-subscribed and distributed, a more efficient system capacity management and subscription processing method is required.

Accordingly, the present invention is to solve the above-mentioned disadvantages and problems of the prior art, the home location registration in the mobile communication market of prepaid subscribers having a distribution structure in which the operator distributes the SIM card after the bulk pre-subscription process. SUMMARY OF THE INVENTION An object of the present invention is to provide a system and method for processing a subscription of a SIM card subscriber that can increase the number of subscribers that can be accommodated.

In addition, the present invention is to manage the subscriber information for the prepaid subscriber on the basis of the actual opening time, rather than the time of the SIM card issuance, that is, on the basis of the subscription time, thereby effectively managing the Sleep SIM card subscriber without burdening the memory capacity limit of the home location register. It is an object of the present invention to provide a SIM card subscriber subscription processing system and method that can be managed, thereby solving the cost burden of the operator due to unnecessary expansion of the home location register or additional license purchase.

In particular, the present invention performs the actual subscription processing of the Sleep SIM card subscriber at the initial location registration time, in order to be able to manage the prepaid subscriber information on the basis of the actual opening time, the subscriber in the memory of the home location register from the initial location registration time. The purpose of this information management is to store and manage the subscriber information until the initial location registration, and to enable the home location register to perform the subscription processing using the information during the opening process (actual subscription processing). The purpose is to provide a separate virtual home location register that is implemented.

Furthermore, according to the present invention, a separate dedicated virtual home location register for managing a sleep SIM card subscriber is provided, so that when a sleep SIM card subscriber and a general subscriber are separately managed in a commercial home location register, the memory capacity of the home location register is exhausted. It is an object of the present invention to provide a SIM card subscriber subscription processing system and method for efficiently and reliably operating a service without burdening subscriber migration that may occur and burdening logic modification of a commercial home location register.

The present invention for achieving the above object is a subscriber identification module (SIM) card subscriber processing system, subscriber information management system for receiving subscriber profile information for subscription processing of subscriber identity module card of the type distributed after pre-subscription; A virtual home location register which is temporarily stored in an internal database, provides the subscriber profile information to the home location register when an initial location registration event for the corresponding subscriber identity module card occurs, and deletes the corresponding subscriber profile information from the internal database; And a home location register that acquires the corresponding subscriber profile information from the virtual home location register and stores it in an internal database to perform subscription processing and location update when an initial location registration event occurs for the subscriber identity module card. It provides a subscription processing system of a SIM card subscriber comprising a.

Here, the database of the virtual home location register stores default profile information which is the same information for a plurality of subscriber identity module cards among subscriber profile information received from the subscriber information management system for subscription processing of the subscriber identity module card. A default area; A virtual area for temporarily storing only mobile identification information among subscriber profile information for the subscriber identification module card; Can be managed separately.

At this time, when the subscriber profile information for the subscription processing of the subscriber identity module card is received from the subscriber information management system, the virtual home location register extracts only the mobile identification information assigned to the subscriber identity module card from the subscriber profile information. And store it in the virtual area, and when the initial location registration event occurs for the subscriber identity module card in which the mobile identification information is stored in the virtual area, the mobile identification information is combined with default profile information stored in the default area to the home location register. Can provide.

Preferably, the database comprises: a default area for storing default profile information having the same information for a plurality of subscriber identity module cards among subscriber profile information received from the subscriber information management system; A virtual area for temporarily storing only mobile identification information among subscriber profile information for the subscriber identification module card; Separated by.

In addition, the present invention for achieving the above object is a home location register for the location registration of the mobile communication terminal, subscriber identification module when the initial location registration event occurs for a specific subscriber identification module card of the type distributed after pre-subscription; In order to temporarily store the subscriber profile information of the card, the subscriber profile information is acquired from a virtual home location register separately constructed and stored in a database to provide a home location register for performing new subscription processing and location update.

Here, when the location update request message for a specific mobile communication terminal is received, the home location register determines whether mobile identification information of the corresponding mobile communication terminal exists in the database, and if the mobile identification information does not exist, the virtual home location. It is preferable to obtain the profile information of the subscriber from the virtual home location register by transmitting the location update request message to the registrar.

The home location register may store the subscriber profile information received from the virtual home location register in a database to perform a new subscription process and transmit the new subscription process result to the virtual home location register.

Another object of the present invention for achieving the above object is to process the subscription of the SIM card subscriber using a virtual home location register separately constructed to temporarily store subscriber identity module (SIM) card subscriber profile information in a form distributed after pre-subscription. CLAIMS 1. A temporary storage step, wherein the virtual home location register receives and temporarily stores subscriber profile information for subscription processing of a subscriber identity module card from a subscriber information management system; A subscriber profile obtaining step of acquiring corresponding subscriber profile information from the virtual home location register by a commercial home location register of the corresponding subscriber when an initial location registration event for the subscriber identity module card occurs; A subscription processing step of the home location registrar storing the subscriber profile information in a database for new subscription processing and providing a subscription processing result to the subscriber information management system; It includes.

At this time, the temporary storage step, the virtual home location register may be a step of extracting only the mobile identification information of the subscriber profile information to store in the virtual area.

In the subscriber profile obtaining step, when the subscriber profile information for specific mobile identification information is requested from the home location register, the virtual home location register combines the corresponding mobile identification information and default profile information stored in the default area. Can be provided as a location register.

In addition, in the method of processing a subscription of a SIM card subscriber of the present invention, before the temporary storage step, the virtual home location register is generated by separating a default area and a virtual area in a database, and a field for storing default profile information in the default area. A DB generation step of generating a mobile identification information storage field in the virtual area; It may further include.

In addition, the step of obtaining the subscriber profile, the first location registration to deliver a location update request message including mobile identification information to the virtual home location register when receiving a location update request message for a specific subscriber identity module card to the home location register.

Accordingly, according to the SIM card subscriber subscription processing system and method of the present invention, in the mobile communication market of prepaid subscribers having a distribution structure in which a service provider distributes a SIM card after mass pre-subscription processing, a larger number is applied to a home location register. Can accommodate subscribers, which can reduce the operator's cost burden due to DB expansion and license purchase.

In addition, according to the present invention, since the subscriber information for the prepaid subscriber is managed not on the basis of the subscription time, but on the actual opening time, the Sleep SIM card subscriber can be effectively managed without burdening the memory capacity limit of the home location register. In addition, there is an advantage that the subscriber information can be efficiently managed by only changing some of the location registration-related logic of the home location register without large logic changes of other systems such as the customer information management system related to the subscriber information processing.

In particular, according to the present invention, since the subscription processing of the Sleep SIM card subscriber is performed through a virtual home location register separate from the commercial home location register, the sleep SIM card subscriber and the general subscriber are separately managed in the commercial home location register. In this case, there is an effect that the service can be efficiently and reliably operated without the burden of subscriber migration that can occur due to the exhaustion of the memory capacity of the home location register and the logic modification of the commercial home location register.

Details of the above object and technical configuration of the present invention and the resulting effects thereof will be more clearly understood from the following detailed description based on the accompanying drawings.

First, FIG. 1 is a diagram illustrating a network configuration of a mobile communication system for explaining the present invention, and FIG. 2 is a diagram for explaining a subscription processing system for a SIM card subscriber according to an embodiment of the present invention.

As shown in FIG. 1, the mobile communication system may include a base station 110, a switch / VLR 120, a home location register 130, a service control device 140, and the like. 130 and the service control device 140 interwork with the subscriber information management system 150 for subscriber information management in accordance with mobile communication service subscription and opening, additional service service registration, termination, change, and the like.

In addition, in the present invention, the home location register 130 and the subscriber information management system 150 interwork with the virtual home location register 160, which is a device provided separately for a Sleep SIM card subscriber.

Unlike the commercial home location register 130, the virtual home location register 160 proposed by the present invention does not perform location registration function or routing information for call processing, additional service information, etc. This is a device that processes only the functions related to subscription processing, such as the function of storing and managing profile information right before the initial location registration point, and providing the corresponding information to the home location register when the initial location registration is performed so that new subscription processing at the time of actual opening is performed. . Therefore, it is apparent that the virtual home location register 160 proposed by the present invention cannot be identified with the general commercial home location register 130 due to its name.

On the other hand, in general, the subscriber information management system 150 provides the subscriber profile information to the home location register 130 when a new subscriber is generated, so that the home location register 130 is stored in the subscriber profile information storage field of the internal database. By storing the subscriber profile information, the subscriber's mobile communication terminal can normally use the mobile communication service.

However, in the case of general subscribers, the service is opened at the same time as the subscription, but in the case of a prepaid subscriber identity module card (hereinafter referred to as 'SIM card'), it is distributed after being pre-subscribed in the name of the SIM card provider. The opening process is performed only when the user who purchases the card 101 is inserted into his mobile communication terminal 100.

In this case, storing all the subscriber profile information for the SIM card in the database of the home location register 130 at the time of joining introduces unnecessary resource waste. Therefore, in the present invention, the SIM is distributed after pre-subscription as described above. The subscriber profile information for the card is managed in a different way from the general subscriber, and the virtual home location register 160 is used for this purpose.

The subscriber profile information management method for the SIM card in the present invention will be described with reference to FIG.

First, in the present invention, the subscriber information management system 150 transmits the corresponding subscriber profile information to the virtual home location register 160 instead of the actual home location register 130 of the corresponding subscriber when the SIM card subscriber is generated. Ensure that subscriber profile information for does not unnecessarily occupy the memory of the home location register before the SIM card is sold. In addition, the subscriber information management system 150 normally provides the subscriber profile information to the home location register 130 when a new subscriber is generated.

When the virtual home location register 160 receives the subscriber profile information on the SIM card from the subscriber information management system 150, the corresponding home profile register 160 stores the subscriber profile information in the memory database 161. The subscriber profile information is provided to the home location register 130 so that the actual subscription process is performed at the time of opening.

When the location registration event for a specific mobile communication terminal occurs, the commercial home location register 130 checks whether the corresponding mobile identification information is stored in the database 131, and if not, the initial location of the SIM card. Recognizing the registration request the corresponding subscriber profile information to the virtual home location register 160, and stores the returned subscriber profile information so that the mobile terminal of the subscriber can normally use the mobile communication service.

On the other hand, the information given by the subscriber information management system 150 for the SIM card subscription type distributed after pre-subscription has the same information for a plurality of subscriber identity module cards, and different unique cards for each card, such as MIN, MDN, ESN, etc. Information is included. In the present invention, the same information for the plurality of subscriber identity module cards is referred to as 'default profile information', and unique information different for each card is referred to as 'mobile identification information'.

As such, since the default profile information is the same information for a plurality of subscribers, all fields for storing the subscriber profile information and pre-allocating the space of the subscriber capacity that the general commercial home location register 130 accommodates in the memory database 131 are acceptable. In contrast, the virtual home location register 160 of the present invention stores the same information for a plurality of subscribers for each subscriber so as not to waste memory, so that the virtual area 161a and the default value are stored in the database 161. The area 161b is divided and generated.

In addition, only the fields for mobile identification information assigned to the SIM card are generated and managed in advance in the virtual area 161a, and the default profile information is stored in advance in the default area 161b so that the mobile identification information is stored in the virtual area 161a. Upon occurrence of the initial location registration event of the stored SIM card, the subscriber profile information is generated by combining the default profile information previously stored in the default area 161b and the mobile identification information of the corresponding SIM card, and providing the same to the home location register 130. Done.

In this case, the virtual home location register 160 stores default profile information in the default area 161b when receiving subscriber profile information from the subscriber information management system 150, and stores mobile identification information in the virtual area 161a. When the subscriber profile information including the same default profile information is received, only mobile identification information may be extracted from the received information and stored in the virtual area 161a.

Meanwhile, in the case of the general commercial home location register 130, all fields for storing subscriber profile information such as mobile identification information, additional service information, and terminal information for each subscriber are previously generated in the memory database 131 by the allowable capacity. When the subscriber profile information for the new subscription processing is received from the management system 150 or the virtual home location register 160, the subscriber profile information is stored in the corresponding area. The area in which the entire subscriber profile information is stored is called the active area 131a.

In summary, in the case of the SIM card distributed after the pre-subscription, since the subscription time and the actual opening time are different, only the minimum information is stored in the virtual area 161a at the time of subscription, and the actual opening time, that is, the first location registration time. The subscriber profile information in which the information stored in the default area 161b and the information stored in the virtual area 161a are combined is stored in the active area 131a.

As described above, in the SIM card subscriber subscription processing system of the present invention, the virtual home location register 160, when the subscriber information management system 150 gives subscriber profile information for SIM card subscription, the subscriber profile information. Only the mobile identification information is extracted from the information and stored in the virtual area 161a for management. After the SIM card 101 is distributed and inserted into the mobile communication terminal 100 to perform initial location registration, the home location register After providing the subscriber profile information combining the mobile identification information and the default profile information of the terminal (or SIM card) to the 130, the mobile identification information stored in the virtual area 161a is deleted, and the subscriber information management system 150 is provided. ) Is notified that the actual subscription and opening has been made, the actual opening standards for other systems, such as service control device 140 that requires subscriber information This subscriber information is managed.

Meanwhile, although the databases in the home location register 130 and the virtual home location register 160 are illustrated as a memory database in FIG. 2, the form of the database is not limited in the present invention.

Next, the subscription processing method of the SIM card subscriber of the present invention described above will be sequentially described through the flowcharts of FIGS. 3 to 5 as follows.

First, FIG. 3 is a flowchart sequentially illustrating a subscription processing procedure of an embodiment for explaining a subscriber information management method of a home location register of the present invention.

As shown, in the present invention, the subscriber information management system 150 does not transmit to the home location register 130 in the case of subscriber profile information for SIM card subscription processing in a form distributed after pre-subscription, and separate virtual home location register. The mobile station transmits the request to step 160 to request subscription processing (S301).

The virtual home location register 160 extracts only the mobile identification information assigned to the corresponding SIM card from the received subscriber profile information and stores the extracted mobile identification information in the previously generated virtual area 161a (S302). Although the mobile identification information is described as a mobile identification number (MIN) in the drawing, this is for convenience of understanding, and the mobile identification information of the present invention is not limited to specific information, and any kind of information different from each SIM card (unique) may be used. Can be.

Next, as the subscriber who purchased the SIM card pre-subscribed as described above inserts the SIM card into his mobile terminal, when a location registration is requested from the mobile terminal (S303), the switch 120 displays the home position. The register 130 transmits a location update request message including mobile identification information of the corresponding SIM card (S304).

At this time, the home location register 130 of the present invention recognizes that the mobile identification information is not in the database, and transmits the corresponding location update request message to the virtual home location register 160 (S305), the virtual home location register. If the mobile identification information is stored in the virtual area 161a, the mobile identification information is generated by combining the mobile identification information with the default profile information to generate the subscriber profile information, and then returns to the home location register 130 to perform a new subscription process. Request (S306).

The home location register 130 stores the subscriber profile information as general subscriber information in each of the pre-generated fields of the active area 131a, performs subscription processing, and performs location update (S307). In response to the location update request message (S308), the switch 120 transmits the location registration response message to the mobile communication terminal 100, thereby completing the location registration (S309).

On the other hand, since the subscription processing result should be provided to each system requiring subscriber information, the home location register 130 stores the subscriber profile information normally, and returns the subscription processing result to the virtual home location register 160 ( In operation S310, the virtual home location register 160 deletes the mobile identification information from the virtual area 161a, transfers the subscription processing result to the subscriber information management system 150, and responds to operation S301 in operation S311. Accordingly, the subscriber information management system 150 drops the subscription information to all the devices that require subscriber information such as SCP 140.

Next, FIG. 4 is a flowchart sequentially showing an operation of a virtual home location register according to an embodiment of the present invention, and FIG. 5 is a flowchart sequentially showing an operation of a home location register according to an embodiment of the present invention.

As shown, the virtual home location register 160 of the present invention first generates and separates the default area 161b and the virtual area 161a in the memory database (S401), and then the default area 161b is assigned to the SIM card. The default profile information is stored in advance (S402-1), and only the field for storing mobile identification information is generated in the virtual area 161a (S402-2). Here, the time point for storing the default profile information in advance may be the time point for receiving the subscriber profile information for the subscription processing of the previous SIM card subscriber.

Next, when profile information of a particular subscriber is received from the subscriber information management system 150 (S403), the virtual home location register 160 of the present invention extracts only mobile identification information from the corresponding subscriber profile information (S406). 131b) (S404). This is a case where the default profile information of the subscriber profile information is stored in advance. If the default profile information in the currently received subscriber profile information is different from the previously stored default profile information, the default profile information is stored in the default area 161b. Will be performed together.

Subsequently, when an initial location registration event using the corresponding SIM card is generated and a location update request message is transmitted from the home location register 130 (S405), the virtual home location register 160 transmits the corresponding subscriber profile information to the home location register 130. (S406), the home location register 130 stores the subscriber profile information in the active area 131a so that the actual subscription process is performed (S407).

When the actual subscription and opening is made as described above, the virtual home location register 160 deletes the corresponding mobile identification information from the virtual area (S408), and informs the subscriber information management system 150 of the new subscription processing result, The information management system 150 enables the following procedure, that is, to perform an operation such as transmitting subscription information to the SCP (S409).

On the other hand, the operation of the home location register 130 that performs the subscription processing of the SIM card subscriber in conjunction with the virtual home location register 160 operating as shown in FIG. 4 will be described as follows.

When the home location register 130 receives the location update request message from the switch 120 (S501), the home location register 130 checks whether the subscriber profile information (mobile identification information) exists in the active area 131a (S502). If it is determined not to obtain the profile information of the subscriber, that is, subscriber profile information for the SIM card from the virtual home location register (160) (S503).

The home location register 130 generates new subscriber information in the database by storing subscriber profile information for the SIM card in the active area 131a (S504), and transmits the new subscription processing result to the virtual home location register 160. (S505). Meanwhile, in the exemplary embodiment of the present invention, the home location register 130 notifies the virtual home location register 160 of the subscription processing result, but the subscription processing result is information required by the subscriber information management system 150. The subscriber information may be transmitted directly to the subscriber information management system 150.

As such, when the actual subscription process (storing subscriber profile information to the home location register) for the SIM card is completed, the home location register 130 includes location information including information of the exchange in which the subscriber is located in the corresponding subscriber profile information field. Stores the location update process and returns a response message to the location update request to the exchanger 120 when the process is completed (S506).

As those skilled in the art to which the present invention pertains may implement the present invention in other specific forms without changing the technical spirit or essential features, the embodiments described above are exemplary in all respects and are not intended to be limiting. You must understand. The scope of the present invention is shown by the following claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included in the scope of the present invention. do.
