Description

Location registration system using pseudo subscriber identification number and method thereof

The present invention relates to a location registration control system and method using the pseudo subscriber identification number. More particularly, the present invention relates to a system and a method for controlling location registration using Pseudo IMSI for various devices selectively connected to the M2M module and the M2M module.

In general, a mobile terminal uses an International Mobile Subscriber Identity (IMSI) as a subscriber identification number used to determine whether a user is a suitable user in communication with a network, and the IMSI is stored in a (U) SIM (Universal Subscriber Identity Module) card. . This IMSI is fixedly assigned prior to the manufacturing phase or sale of the mobile communication terminal. It is also used to identify subscribers during location registration.

However, since IMSI is a resource like IP (Internet Protocol), if the application target increases to test cards, repeaters, and M2M modules, IMSI is likely to be depleted someday. Currently, IP is moving from IPv4 to IPv6 due to resource exhaustion.

Here, M2M (Machine to Machine) is a remote management and control solution that supports communication between machines by connecting the M2M module and the device by using a wired or wireless communication method to a series of user traffic data on a general wired or wireless network.

In the case of the M2M module, the mobile network connection is basically supported, but the mobile network connection may be optional depending on the purpose of the device to which the M2M module is connected. For example, a car navigation system mounted on a vehicle may use only a navigation function and may not use a service function provided by accessing a mobile communication network even though the M2M module is provided. However, according to the user's inclination, the use of only the navigation function and the mobile communication service function are likely to be permanently unused.

Therefore, the number of such cases increases, the more the number resources of IMSI are wasted, which is emerging as an important issue to be solved from the point of view of the operator who wants to expand M2M service.

The technical problem to be achieved by the present invention is to use a subscriber identification number (PSEudo IMSI) previously assigned to the M2M module at the time of first access to the mobile communication network according to the user's selection. The present invention provides a location registration control system and method for allocating an IMSI.

According to one aspect of the invention, a location registration control system is provided. In the location registration control system of the mobile communication network, the location registration control system requests the initial location registration by using the pseudo subscriber identification number in the location registration control system of the mobile communication network and uses the subscriber identification number to actually use for the mobile communication service. A location registration unit for requesting location registration again by using the assigned subscriber identification number; And a location registration control server for allocating the subscriber identification number to the location registration unit when the first location registration request is received from the location registration unit using the pseudo subscriber identification number.

According to another feature of the present invention, a location registration control method is provided. The location registration control method is a method in which a communication device equipped with a mobile communication function and a location registration function controls location registration. (A) Requesting initial location registration to a mobile communication network using a pseudo subscriber identification number to actually perform mobile communication. Receiving a subscriber identification number to be used for the service; And (b) requesting location registration again using the subscriber identification number assigned in step (a).

According to still another aspect of the present invention, a method for controlling location registration includes: (a) a location registration request from the communication device in a method for controlling location registration of a communication device equipped with a mobile communication function and a location registration function in a mobile communication network; Determining whether the subscriber identification number used for the location registration request is a pseudo subscriber identification number if received; And (b) in the case of the pseudo subscriber identification number as a result of the determination of step (a), actually assigning the subscriber identification number to be used for the mobile communication service and providing the same to the communication device.

According to an embodiment of the present invention, even if a user does not use a mobile communication service, a fixed number of subscriber identification numbers (IMSI) can be fixed in preparation for accessing a mobile communication network, thereby solving the conventional problem of wasting subscriber identification resources. .

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and like reference numerals designate like parts throughout the specification.

Throughout the specification, when a part is said to "include" a certain component, it means that it can further include other components, without excluding other components unless specifically stated otherwise. In addition, the terms “… unit”, “… unit”, “… module” described in the specification mean a unit that processes at least one function or operation, which may be implemented by hardware or software or a combination of hardware and software. Can be.

In an embodiment of the present invention, pseudo IMSI (hereinafter referred to as pseudo IMSI) is newly added to minimize waste of resource allocation (International Mobile Subscriber Identity, hereinafter referred to as 'IMSI'). As a proposed concept, it is used only at initial location registration. Pseudo IMSI is defined using some localized number resources of the total number resources to be used for the assignment of IMSI. And as before, the IMSI actually used for location registration is allocated from the mobile communication network during the initial location registration using the pseudo IMSI, and the location registration procedure is completed only by registering the location again.

This solves the conventional problem in that the IMSI resources are wasted due to the fixed allocation of IMSI in preparation for accessing the mobile communication network even when the user does not use the mobile communication service.

In the following description, 'IMSI' refers to a real IMSI assigned by a mobile communication network through a location registration request using a pseudo IMSI, and is used separately from a 'pseudo IMSI'.

Now, a position registration control system and method using a pseudo IMSI according to an embodiment of the present invention will be described in detail with reference to the drawings.

≪ Example 1 >

1 shows a configuration of a position registration control system using a pseudo IMSI according to a first embodiment of the present invention.

As shown in FIG. 1, the location registration control system includes a location registration unit 100 and a location registration control server 200. Here, each of the location register 100 and the location registration control server 200 is a minimized configuration unit that implements a function related to location registration control using a pseudo IMSI. It can be mounted as.

The location registration unit 100 receives the IMSI actually used while registering the first location in the mobile communication network using a pseudo IMSI (Pseudo IMSI) previously assigned. Location registration is completed by requesting location registration from the mobile communication network again using the assigned IMSI.

The location registration unit 100 includes a memory 120 and a location registration control module 140 in detail.

Memory 120 includes a first IMSI file 122 storing IMSI and a second IMSI file 124 storing pseudo IMSI. Here, the first IMSI file 122 stores the assigned IMSI when the actual IMSI to be used is allocated. If no IMSI is actually used, the so-called null value (eg 'FFFF') is stored.

In addition, the second IMSI file 124 contains a pseudo IMSI previously assigned by the operator. At this time, the pseudo IMSI follows the international standard of IMSI.

The international standard of IMSI is composed of Mobile Country Code (MCC), Mobile Network Code (MCN) and Mobile Subscriber Identifier Number (MSIN), and has a maximum of 15 digits. At this time, the first three digits are MCC, the next two to three digits are MNC, the remaining maximum 10 digits are composed of MSIN.

The MCC and the MNC are information for uniquely identifying a mobile subscriber's home network in any network in the world. In other words, the structure of IMSI is a structure in which other networks providing roaming services can search the home network by analyzing the maximum first six digits of IMSI. The MSIN is information for uniquely identifying the mobile communication terminal when the MCC and the MNC are given.

The location registration control module 140 accesses the first IMSI file 122 of the memory 120 and determines whether the IMSI is stored. If the IMSI is not stored, the IMSI is allocated from the location registration control server 200 while requesting location registration using the pseudo IMSI extracted from the second IMSI file 124. After that, request registration of location again by using assigned IMSI.

Detailed operation of the location registration control module 140 will be described with reference to FIG. 2.

The location registration unit 100 described above is mounted as a function in a communication device that performs location registration in a mobile communication network to provide a mobile communication service. In this case, the location register 100 may be implemented as a function added as a new function of the location register 100 provided in the existing mobile communication terminal. In addition, it is mounted on a machine to machine (M2M) module can control the location registration of the M2M module.

The location registration control server 200 allocates the IMSI to the location registration unit 100 when the location registration unit 100 requests the location registration using the pseudo IMSI.

The location registration control server 200 includes a processing unit 220, an allocation unit 240, and a mapping DB 260 in detail. Here, the processor 220, the allocator 240, and the mapping DB 260 may be implemented by mounting the respective functions in the home location register (HLR) of the mobile communication network. In addition, the processor 220 may be implemented as one function in the home location register, and the allocator 240 and the mapping DB 260 may configure the location registration control server 200 to be added in a new configuration to the network.

The processor 220 processes a location registration request of the location register 100 and stores location registration information and subscriber information. In addition, the processor 220 includes pseudo IMSI information to determine whether the IMSI used in the location registration request is a pseudo IMSI. That is, it stores IMSI resource information defined for use as a pseudo IMSI. For example, the number resource to be allocated to the MCC + MNC region may be configured with a specific number that is different from the IMSI so that the number resource to be allocated to the MCC + MNC region can be viewed to distinguish whether or not it is a pseudo IMSI.

When the location registration unit 100 requests registration of the location using the pseudo IMSI, the allocation unit 240 allocates the IMSI and transmits the location to the location registration unit 100. In this case, the method of transmitting the IMSI to the location registration unit 100 by the allocator 240 may use an over the air (OTA) method.

The mapping DB 260 stores a mapping table composed of mapping information between a pseudo IMSI and an IMSI defined to be allocated to the pseudo IMSI. That is, the mapping table includes information defining what IMSI to allocate when a location registration request using the pseudo IMSI is received for each pseudo IMSI predetermined for use by an operator.

The processor 220 may determine whether the IMSI is requested as a pseudo IMSI by checking whether the requested IMSI is registered as a pseudo IMSI in the mapping table.

The allocator 240 extracts the IMSI mapped to the pseudo IMSI requested by the location register 100 from the mapping DB 260 and provides the location register 100 to the location register 100. Table 1 below shows a mapping table.

First field Second field 45002 0000000001 45008 1050084584 45002 0000000002 45008 1050084679 45002 0000000003 45008 1270002019 45002 0000000004 45008 1280007862 45002 0000000005 45008 1600003838

The first field of the mapping table contains a pseudo IMSI and the second field contains an IMSI. That is, the allocator 240 searches the first field for the pseudo IMSI received from the location register 100 that has requested the location registration. The IMSI included in the second field corresponding to the pseudo IMSI is extracted and allocated to the location register 100.

In the above table, similar to the IMSI recorded in the second field, '45002' of the pseudo IMSI recorded in the first field represents 'MCC + MNC' and the remaining numbers represent MSIN. In other words, 'MCC + MNC' of pseudo IMSI is identical and MSIN is composed differently. At this time, the number resource used for allocation to the pseudo IMSI is selected by the operator according to various embodiments.

Such pseudo IMSI is fixedly assigned to the location register 100 by the operator, but the number of assignable pseudo IMSIs is limited in advance. Therefore, the same pseudo IMSI may be allocated among the location registers 100 assigned within the limited range. Thus, the total number of pseudo IMSIs is preferably set such that the probability of location registration being requested with the same pseudo IMSI is as low as possible.

Meanwhile, the allocator 240 allocates the IMSI to the location register 100 and then deletes the IMSI assigned to the location register 100 from the mapping table. The new IMSI corresponding to the pseudo IMSI is added to the mapping table. In this case, when another location registration unit 100 requests the location registration using the same pseudo IMSI, it is possible to allocate a new IMSI.

Detailed operations of the location registration control server 200 described above will be described with reference to FIG. 3.

2 is a flowchart showing the operation of the location register according to the first embodiment of the present invention. The location registration control method of the location registration unit 100 will be described in connection with each detailed configuration of the location registration unit 100 of FIG. 1.

As shown in FIG. 2, when the location registration control module 140 recognizes that the situation requires location registration (S101), the location registration control module 140 accesses the first IMSI file 122 (S103) and determines whether there is an IMSI allocation (S105). . Here, step S101 refers to a case in which power is turned on or when location registration is required to provide a mobile communication service.

As a result of the determination in step S105, the location registration control module 140 extracts the IMSI stored in the first IMSI file 122 and requests the location registration from the mobile communication network when the IMSI is allocated (S107).

When the location registration control module 140 determines in step S105 that the IMSI is not assigned, the location registration control module 140 determines the initial location registration. The location registration control module 140 accesses the second IMSI file 124 (S109) and extracts the pseudo IMSI (S111).

The location registration control module 140 requests initial location registration to the mobile communication network using the pseudo IMSI extracted in step S111 (S113).

When the IMSI is received from the mobile communication network (S115), the location registration control module 140 stores the received IMSI in the first IMSI file 122 (S117) and resets the received IMSI. Then, since the same effect as when the power is off, the position registration control module 140 performs again from step S101. That is, the location registration unit 100 performs the location registration request operation again as if the initial location registration. At this time, since the IMSI received in step S115 is stored in the first IMSI file 122, the location registration is completed through step S107.

3 is a flowchart showing the operation of the location registration control server in the first embodiment of the present invention. The location registration control method of the location registration control server 200 will be described in connection with each detailed configuration of the location registration control server 200 of FIG. 1.

As shown in FIG. 3, when a location registration request is received from the location registration unit 100 (S201), the processor 220 determines whether location registration using a pseudo IMSI is performed (S203).

The processor 220 completes the location registration if it is determined that the location is not registered using the pseudo IMSI as a result of the determination in step S203 (S205).

On the other hand, if it is determined in step 203 that the location registration using the pseudo IMSI as a result of the determination in step 203, the processor 220 requests the IMSI allocation. Then, the allocator 240 searches the mapping table (S207), extracts the IMSI mapped to the pseudo IMSI received in step S201, and assigns it to the location registration unit 100 (S209).

In addition, the allocation unit 240 transmits the IMSI allocated in step S207 to the location registration unit 100 (S211).

5 shows an internal configuration of an M2M module according to a second embodiment of the present invention.

As shown in FIG. 5, the M2M module 400 includes the configuration of the location registration unit 100 described with reference to FIG. 1, and description thereof will be omitted.

In addition, the M2M module 400 includes a device connection unit 420, a device recognition unit 440, and a communication unit 460.

The device connection unit 420 connects the M2M module 400 to a device 300 such as a mobile phone, a PDA, a computer, a laptop, an MP3 player, a camera, a game machine, a telematics machine, a fitness machine, a smart terminal, a repeater, an environmental sensor, and the like. Play a role.

The device recognition unit 440 checks the recognition information of the connected device 300 and performs booting for interworking with the connected device 300. Here, the device recognition information may be identification information such as the type, model information, and manufacturer of the device 300 obtained from the device 300 at the request of the device recognition unit 440. In addition, the device recognizing unit 440 may determine the type of the device 300 connected to each of the pins of the device connection unit 420 in advance and determine the corresponding device type when the device 300 is connected.

In this case, when the user requests the execution of the mobile communication service application provided in the device 300 or the M2M module 400, the device recognition unit 440 commands the location registration unit 100 to drive the location registration. That is, the point in time at which the user executes the service application requiring the access to the mobile communication network becomes the point in time of registering the location of the location register 100.

The communication unit 460 supports a mobile communication function so that the M2M module 400 can communicate with the HLR 500 and the OTA server 600 by accessing the mobile communication network.

6 shows a location registration control method according to a second embodiment of the present invention. That is, a series of processes for controlling location registration through linkage between the components described with reference to FIGS. 4 and 5 are illustrated.

As shown in FIG. 6, when the execution of the mobile communication service is selected by the user (S301), the device 300 requests the execution of the M2M module 400 (S303).

The M2M module 400 checks whether an IMSI required for location registration for providing a mobile communication service is allocated, and if not, extracts a pseudo IMSI and requests a location registration from the HLR 500 (S305).

The HLR 500 transmits the pseudo IMSI to the location registration control server 200 ′ when the IMSI received when the location registration request is a pseudo IMSI is performed at step S305 (S307).

The location registration control server 200 ′ searches for the mapping table (S309), extracts the IMSI mapped to the pseudo IMSI received in step S307, and assigns it to the M2M module 400 (S311). In addition, the OTA server 600 requests to transmit the IMSI allocated in step S309 to the M2M module 400 (S313).

The OTA server 600 generates an IMSI assignment message containing the IMSI received in step S313 (S315) and transmits the message to the M2M module 400 (S317). At this time, the IMSI assignment message uses an existing OTA message defined for OTA service between the M2M module 400 and the OTA server 600 or a new OTA message previously negotiated between the M2M module 400 and the OTA server 600. Can be used. Here, the pre-negotiated new OTA message means a message defined separately for the transmission of the allocated IMSI. At this time, it is obvious that the location registration unit 100 of the M2M module 400 is provided with a function of recognizing and processing the OTA message defined as described above.

After receiving the IMSI allocation message from the OTA server 600, the M2M module 400 requests registration of the location back to the HLR 500 using the assigned IMSI (S319).
