Method for managing restriction parameters of a mobile terminal and a mobile terminal performing the same {Method For Managing Of Personalization Parameter Of Mobile Equipment And Mobile Equipment Performing The Same}

The present invention relates to a mobile terminal, and more particularly, to a method for managing usage restriction parameters of a mobile terminal that can be applied to a mobile terminal equipped with a subscriber authentication module and a mobile terminal performing the same.

Universal Subscriber Identity Module (USIM: hereinafter abbreviated as 'USIM') is a Subscriber Identity Module (SIM) used in Universal Mobile Telecommunications System (UMTS), a third generation mobile communication system. As Wideband Code Division Multiple Access (WCDMA) has evolved from Europe's Global System for Mobile communications (GSM), SIM, GSM's subscriber authentication module, has evolved.

USIM is used as a platform to support various additional services such as user authentication, global roaming, e-commerce, and transportation cards through the expandability of functions and internal memory.

In particular, the USIM includes a profile indicating the specifications of the mobile terminal, subscriber information, and user personal information (for example, a telephone number and personal record information), so that the USIM is issued from a mobile operator to which the user subscribes. When the card is installed in the mobile terminal purchased by the user, it can be used regardless of the type.

That is, the user can select and compatible the mobile terminal, and the user who has purchased the USIM card once can use it freely regardless of the mobile communication provider or the mobile terminal.

However, in order to guarantee the mobility of the mobile terminal as described above, a personalization function for restricting the use of the mobile terminal by unauthorized users, malicious users, or unjust users is required, and therefore, it is used in 3GPP TS 22.022. Five categories of personalization are disclosed (ie Network, Network Subset, Service Provider (SP), Corporate, SIM / USIM).

Each of the restriction categories may be set through input of a corresponding control key, and an initial input of a control key may be input by a user through a keypad or may be input and stored through a process defined by a manufacturer of a mobile terminal. .

In addition, the Network, Network Subset, SP, and Corporate categories of the usage restriction category may be released through over-the-air (OTA) by the network.

As described above, in order to control the usage restriction of the mobile terminal through the OTA in the network, a method for managing the control keys for each of the usage restriction categories in common between the mobile terminal and the network is required.

Accordingly, it is a first object of the present invention to provide a method for managing usage restriction parameters of a mobile terminal, which enables to control usage limitation characteristics of the mobile terminal in a network.

It is also a second object of the present invention to provide a mobile terminal having a management function of a usage restriction parameter for controlling the usage restriction characteristic of the mobile terminal in a network.

The usage restriction parameter information may include at least one of a Network Control Key (NCK), a Network Subset Control Key (NSCK), a Service Provider Control Key (SPCK), and a Corporate Control Key (CCK). The SMS message may include an OTA_type, an International Mobile Equipment Identity (IMEI), and the usage restriction parameter information. In the parameter transmitting step, a control key that is not generated among the restriction parameter information may be recorded and transmitted as a predetermined value.

In addition, a mobile terminal having a limit parameter management function for achieving the second object of the present invention is a storage unit storing the limit parameter information and if the registration of the location is successfully performed, the limit parameter information to the network via the SMS message; It may include a control unit for transmitting. The controller may include at least one of an OTA_type, an International Mobile Equipment Identity (IMEI), a Network Control Key (NCK), a Network Subset Control Key (NSCK), a Service Provider Control Key (SPCK), and a Corporate Control Key (CCK). Information can be included and transmitted. The controller may record and transmit a control key which is not generated among the usage restriction parameter information as a preset value.

Referring to FIG. 2, when power is first applied to the mobile terminal (step 210), the mobile terminal determines whether at least one control key is generated among control keys for five restriction categories (step 220).

Here, the mobile terminal can determine whether the control key is generated by determining whether the control key is stored in the storage unit.

If it is determined in step 220 that the control key is not generated, the mobile terminal generates a control key for at least one predetermined restriction category (step 230). Here, the control key for each of the restriction of use categories may be generated by the user or the administrator through the keypad provided in the mobile terminal or may be generated through a process defined by the manufacturer of the mobile terminal.

If it is determined in step 220 that at least one control key is generated, the mobile terminal performs a location registration procedure (step 240). Here, the mobile terminal reads out the International Mobile Station Identity (IMSI) from the subscriber authentication module (ie, USIM), and uses the read IMSI to perform Mobile Switching Center (MSC) and / or Serving Service (SGSN) of the UMTS core network. The location registration procedure may be performed by sending an Attach Request message or a Routing Area Update Request message to the GPRS Supporting Node.

The mobile terminal may transmit an Attach Request message when the power is applied, and may transmit a Routing Area Update Request message when the mobile terminal moves in an idle state.

Thereafter, the mobile terminal determines whether it is in a normal operation state (step 250). In step 250, the mobile terminal may determine whether the location registration is successful based on whether the Attach accept message provided from the network is received, and may determine whether the mobile terminal is in a normal operating state.

If it is determined in step 250 that the mobile terminal is in a normal operating state, the mobile terminal transmits a control key of the restricted category to the network via the OTA (step 260).

Specifically, the mobile terminal may transmit a control key to the network through a short message service (SMS) message, and the SMS message includes a protocol ID (PID) indicating that the transmitted message is an OTA message, and user data (TP-UD). May be included.

Here, the user data included in the SMS message may be, for example, OTA_type, IMEI, NCK, NSCK, SPCK, CCK, etc., and OTA_type may mean that the message content is registration of a control key.

In addition, a control key not generated among the NCK, NSCK, SPCK, and CCK records and transmits all the digits as a preset default value (for example, 'FFFFFFFF' in hexadecimal). In addition, the control key information transmitted through the SMS message from the mobile terminal may be stored in the HLR of the network.

The process of managing a restriction of use parameter of the mobile terminal shown in FIG. 2 may be performed, for example, when the mobile terminal joins the mobile communication service and the service is started.
