It manages the packet data, handles routing of packet data, and provides an interface for connecting the WDCMA network to the Internet.

The packet switching support node 35 and the packet switching gateway 36 may be referred to as a packet switching unit 200. The packet exchange unit 200 transmits and receives data in packet units in transmitting and receiving data of the user terminal.

The external network 40 is a network connected to the outside through the circuit switching unit 100 or the packet switching unit 200. The circuit switching unit 100 is related to the transmission and reception of circuits such as voice calls. The circuit switching unit 100 may be a public switched telephone network (PSTN), an integrated services digital network (ISDN), or a public land mobile network (PLMN). The packet exchange unit 200 is related to the transmission and reception of packets. The packet exchange unit 200 may be an Internet Protocol (IP) network such as the Internet.

The home location register (HLR) 52 stores and manages the location information of the subscriber, and the authentication center (AuC) generates an authentication vector and performs a subscriber authentication function. In general, an authentication center (AuC) is interlocked with a home location register (HLR) and they can exchange information with each other.

The Equipment Identity Register (EIR) 50 checks or manages identification information related to hardware of the user terminal. The device identification register 50 stores the information of the stolen or lost terminal, and compares the user terminal information received from the circuit switch 31 with the previously stored terminal information when the subscriber authentication and location registration request are made. 10) You can decide whether you have stolen or lost your car. To this end, the device identification register 50 stores the information of the stolen and lost terminals in a black list.

The device identification register 50 may receive the terminal information from the user terminal 10, and grasp the service information that can be provided to the user terminal 10. In addition, the device identification registerer 50 determines whether or not the specific service requested from the user terminal 10 can be provided to the user terminal 10. The device identification registerer 50 determines whether the specific service requested from the user terminal 10 can be provided, and if the specific service can be provided to the user terminal 10, the device identification register 50 specifies the service providing server 60. Request a service. However, when a specific service cannot be provided to the user terminal 10, the device identification registerer 50 notifies the user terminal 10 that the service is not provided.

2 is a flowchart illustrating a method of determining whether to provide a service using terminal information according to an embodiment of the present invention, and FIG. 3 illustrates a data structure of IMEISV information according to an embodiment of the present invention. 4 shows a mapping table structure corresponding to an SVN in IMEISV information according to an embodiment of the present invention.

Referring to FIG. 2, the user terminal 10 transmits IMEISV information, which is terminal information, to the circuit switch 31 or the packet switched support node 35 (S200). The circuit switch 31 or the packet switched support node 35 transmits the IMEISV information to the device identification register (S220).

For example, it may be assumed that a specific service is requested from the user terminal 10 in an environment where terminal mobility is allowed. For example, a 64 chord ringtone download service may be requested from the service providing server 60 from the user terminal 10. In general, regardless of whether the user terminal 10 can receive the 64 chord ringtone download service or the server providing the 64 chord ringtone, the user terminal 10 receives the 64 chord ringtone download service to the core network 30. Check if you can.

Therefore, if it is determined whether or not the corresponding service can be provided to the user terminal 10 according to the hardware or software specification of the user terminal 10, the core network load can be reduced. In addition, the user terminal 10 in the core network 30 in an environment in which terminal mobility is allowed, for example, in which the user terminal 10 is replaced by inserting a user's UICC card or USIM card into another terminal. There may be cases where it is not clear whether the service is provided.

As such, in an embodiment of the present invention, whether the service is provided may be determined using terminal information provided from the user terminal 10 with respect to the service requested from the user terminal 10. Therefore, the request service of the user terminal 10 can be quickly processed without being connected to another database server (not shown) of the core network 30.

The terminal information provides information on the user terminal 10 so that service information can be obtained using the terminal information. For example, the terminal information may be International Mobile Station Equipment Identity and Software Version Number (IMEISV) information. IMEISV information will be described later.

'Service information' referred to in an embodiment of the present invention refers to information about a service that can be supported according to the user terminal 10. For example, if the user terminal 10 is equipped with a DMB receiver, the DMB service is possible. If the user terminal 10 is equipped with a GPS receiver, it is determined that the navigation service is possible. Information about whether a service of the 'DMB service' or the 'direction service' can be provided to the user terminal 10.

Referring to FIG. 3, the data structure of IMEISV information 300 according to an embodiment of the present invention may include an International Mobile Station Equipment Identity (IMEI) field 310 and a Software Version Number (SVN) field 320. have. The IMEISV information 300 refers to information indicated by information included in the IMEI field 310 and the SVN field 320.

IMEI field 310 includes device identification information. The general IMEI field 310 may include a type approval code (TAC) 330, a final assembly code (FAC) 340, and a serial number (SNR) value. In general, the IMEI field 310 may be represented by a 14-digit decimal number. The identification number of the user terminal may be indicated by a 14-digit decimal number included in the IMEI field 310, and the device identification register 50 is stolen or lost for the user terminal by the information included in the IMEI field. It can be seen.

In addition to the IMEI field 310, the IMSI (International Mobile Subscriber Identity) information may be included and transmitted to the device identification register 50. At this time, since the IMSI information includes information about the user, and the IMEI field 310 includes device identification information about the device, the device identification register 50 uses the IMSI information and the information included in the IMEI field 310. It is easy to identify stolen or lost devices.

Meanwhile, the IMEISV information 300 may further include a Software Version Number (SVN) field together with the IMEI field. The SVN field 320 is composed of 2 bytes, and in general, arbitrary information may be included by the terminal manufacturer. The terminal manufacturer may include any information composed of two bytes, for example, a software version of the user terminal, in the SVN field 320, and the information may be substantially provided by the network operator controlling the mobile communication network. This information is rarely used.

Therefore, in an embodiment of the present invention, the service identification information that can be supported to the terminal may be provided to the terminal using the SVN field 320 which is not substantially used. According to an embodiment of the present invention, the service identification information that can be supported for the user terminal 10 is loaded in the SVN field 320 and transmitted to the device identification register 50 so that the device identification register 50 uses the service identification information. By identifying the service information that can be provided to the user terminal (10).

For example, as shown in FIG. 3, if the SVN field 320 is configured as 2 bytes, the SVN field 320 may be configured as 16 bits. Thus, 0 or 1 may be included for each bit. For example, the first bit 321 has a ringtone of the user terminal 16 chords, the second bit 322 has 32 ringtones, the third bit 323 has a ringtone 64 chords, and the fourth bit 324 has a GPS receiver. The fifth bit 325 may be defined to indicate service identification information of the user terminal up to the sixteenth bit, such as a DMB receiver. If each bit of the SVN field 320 is 0, the corresponding service may not be provided to the user terminal. If each bit is 1, the corresponding service may be provided to the user terminal. Accordingly, when the SVN field is configured with 16 bits, the SVN field may include information indicating whether 16 types of services are provided.

As another example, the mapping table 400 corresponding to the service information stored in the SVN field 320 may be utilized. As an example of using the mapping table 400, a specific number 410 may be assigned to the SVN field 320 as shown in FIG. 4, and a mapping field 420 listing service information corresponding to the specific number 410 is provided. Can be used. For example, if the number '01' is given to the SVN field 320, the service information that can be provided to the corresponding user terminal may be determined according to the mapping field 420 '01' storing the corresponding service information. have.

In this way, a specific number 410 for the corresponding user terminal 10 is assigned in the SVN field 320, and service information that the user terminal 10 can provide according to the specific number 410 is classified by type. Correspond to one mapping field 420. The specific number 410 carried in the SVN field 320 may depend on the specification of the terminal manufactured by the manufacturer and the mobile communication network in which the terminal is used, depending on the user terminal 10.

Referring back to FIG. 2, the device identification register (EIR) 50 receives IMEISV information from the received circuit switch 31 or the packet switched support node 35 (S220). The IMEISV information 300 may include device identification information in the IMEI field 310 and service identification information in the SVN field 320.

The device identification registerer 50 identifies service information that can be provided to the user terminal 10 using the IMEISV information (S230). For example, the device identification registerer 50 may use the service identification information included in the SVN field to grasp the service information that can be provided to the user terminal 10 or the device identification included in the IMEI field 310. The service information that can be provided to the user terminal may be grasped using the information and the service identification information included in the SVN field 320. The device identification registerer 50 may store the service information of the identified user terminal in a database or any storage (S240).

On the other hand, the user terminal 10 requests the circuit switch 31 or the packet-switching support node 350 to provide a specific service (S250). For example, the specific service may request to provide various services provided by the mobile communication network, such as requesting to provide a 64 chord ringtone download service or requesting DMB reception.

The circuit switch 31 or the packet switched support node 350 transmits a specific service provision request signal requested from the user terminal 10 to the device identification register 50 (S260). The device identification registerer 50 determines whether the corresponding service can be provided to the user terminal 10 with respect to the specific service request signal (S270).

Whether the corresponding service can be provided to the user terminal 10 may be determined by checking whether the specific service requested by the user terminal 10 is included in the service information obtained using the IMEISV information transmitted in advance. Alternatively, service identification information included in the SVN field may be used among IMEISV information corresponding to the user terminal 10.

As an example of determining whether the corresponding service can be provided to the user terminal 10, whether to provide corresponding service corresponding to service information indicated by a binary number of 0 or 1 included in the SVN field as shown in FIG. 3 is provided. To judge. If the user terminal 10 applies for the 16-chord ringtone download service, as shown in FIG. 3, since the first bit is '1', it may be determined that the 16-chord ringtone download service can be provided. However, if the user terminal 10 requests the 32-chord ringtone download service, as shown in FIG. 3, since the second bit is '0', it is determined that the 32-chord ringtone download service cannot be provided.

As another example of determining whether the corresponding service can be provided to the user terminal 10, the mapping table 400 may be utilized as shown in FIG. 4. Given a two-digit specific number 410 provided in the SVN field, it can be determined whether the corresponding service can be provided to the user terminal 10 using the service information embedded in the mapping field 420. have. If the specific number 410 of the SVN field is '01' and the request service of the user terminal 10 is the 16-tone ringtone download, the 16-tone ringtone is downloaded with reference to the mapping field 420 corresponding to '01'. It can be determined that the service can be provided. However, if the user terminal 10 requests the 32 chord ringtone download service, the mapping field 420 determines that the 32 chord ringtone download service cannot be provided.

As another example of determining whether the corresponding service can be provided to the user terminal 10, it is determined whether the corresponding service information can be provided using TAC information in the IMEI field and service identification information in the SVN field. The value provided by the TAC may determine the device type or device name of the user terminal 10 and determine whether the corresponding service information can be provided using the service identification information in the SVN field.

Referring back to FIG. 2, if it is determined that the device identification register 50 is capable of providing a service for a specific service requested from the user terminal 10, a possible signal is sent to the circuit switch 31 or the packet switched support node 51. It transmits (S280). Upon receiving the enable signal, the circuit switch 31 or the packet-switching support node 51 requests a specific service from the service providing server 60 (S285). The service providing server 60 may provide a corresponding service to the user terminal 10 with respect to a specific service request. In addition, the circuit switch 31 or the packet-switching support node 51 which has received the enable signal may transmit the enable signal indicating that the corresponding service can be provided to the user terminal 10.

On the other hand, if it is determined that the device identification register 50 is unable to provide a service for the specific service requested from the user terminal 10, the device identification register 50 transmits an impossible signal to the circuit switch 31 or the packet switched support node 51 (S290). ). Upon receiving the disable signal, the circuit switch 31 or the packet switched support node 51 transmits the disable signal to the user terminal 10 (S295). The display or message on the screen of the user terminal 10 may notify the user terminal 10 that the use of the specific service requested by the user terminal 10 is not available.

As described above, it may be determined whether the corresponding service can be provided to the user terminal 10 by using the terminal information for the specific service requested from the user terminal 10. In response to the determination, the service providing server 60 may be requested to provide the corresponding service, or the user terminal 10 may not be provided. Therefore, by using the information on the SVN field that is not useful, it is possible to easily grasp the service information that can be provided to the user terminal 10, the device identification register 50 for the specific service requested from the user terminal 10 In this case, network traffic can be reduced.

The specific service provision refers to a service requested from the user terminal 10.

The circuit switch 31 or the packet switched support node 35 transmits the received IMEISV information and the specific service request signal to the device identification register 50 (S520). The device identification registerer 50 obtains service information indicating a service that can be provided to the user terminal 10 using the IMEISV information (S530). The device identification registerer 50 may store the IMEISV information or the service information obtained from the IMEISV information for the user terminal 10 in a database (S540).

The device identification registerer 50 determines whether the specific service request transmitted from the user terminal 10 can be provided to the user terminal 10 (S550). Whether it can be provided to the user terminal 10 can be determined using the IMEISV information transmitted from the user terminal 10, or can be determined using the IMEISV information or the service information obtained from the IMEISV information stored in the database. .

If it is determined that the specific service requested to the user terminal 10 is available, the device identification registerer 50 transmits the enable signal to the circuit switch 31 or the packet switched support node 35 (S580). Upon receiving the enable signal, the circuit switch 31 or the packet switched support node 35 requests the service providing server 60 capable of providing the corresponding service to the user terminal 10 to provide the corresponding service (S585).

On the other hand, if it is determined that the provision of the specific service requested by the user terminal 10 is impossible, the device identification register 50 transmits an impossible signal to the circuit switch 31 or the packet switched support node 35 (S590). The circuit switch 31 or the packet switched support node 35 transmits the impossible signal to the user terminal 10 (S595). The user terminal 10 may notify the user that a specific service is not provided by using the screen or a message of the impossible signal.
