2 is a unique code storage state diagram of a mobile communication terminal according to the present invention.

The present invention relates to a method for storing a unique code of a mobile communication terminal, and in particular, a mobile communication terminal that can improve a data processing speed as well as the efficiency of memory use by storing a plurality of carrier codes in a simple format. It relates to a unique code storage method.

In mass production of mobile communication terminals, a unique identification number is assigned to each terminal to define a mobile communication network in which the terminal can be used. Thus, the unique identification numbers stored in the memory of the terminal include an electronic serial number (ESN) of the terminal, a mobile identification number (MIN), a primary channel, and the like.

Here, MIN is a telephone number of a mobile communication terminal, which is usually composed of 10 digits (10digits) and can be stored and updated through programming.

However, as the mobile communication network becomes wider, IMSI (Internal Mobile), which adds a mobile country code (MCC) and a carrier code (Mobile Network Code, MNC) for identification of service providers, to NIMs By saving Station Identity, it supports international roaming function.

1 is a structural diagram of IMSI. As shown in FIG. 1, the IMSI consists of a 3-digit code MCC, which is a country code, a 2-digit code MNC, which is a service provider code, and a telephone number of 10 digits.

Here, the space for storing the operator code is allocated 16 variables, that is, a memory capable of storing 16 bits, and when storing more than one operator code, 16-bit memory is additionally allocated to store the added operator code.

Therefore, in order to be able to use a service in a country having a country code of 334 and to use a service having a provider code 1 and a provider code 2, first, four 16-bit memories are allocated, and each country code 334 and The operator code 1, country code 334 and the operator code 2 had to be stored. The program to store this code is:

Conventional Program Structure

NetworkBlockControlRegTag.status = A; // Allow

NetworkBlockControlRegTag.networkOperatorId [0] .mcc = 334; // Country Code 334

NetworkBlockControlRegTag.networkOperatorId [0] .mnc = 1; // business code1

NetworkBlockControlRegTag.networkOperatorId [1] .mcc = 334; // Country Code 334

NetworkBlockControlRegTag.networkOperatorId [1] .mnc = 2; // business code2

As such, according to the conventional method of storing the country code and the operator code, as the number of available countries or operators increases, the memory to be stored must be increased, thereby reducing the efficiency of using the memory and delaying the processing time when storing or processing the data. There is a problem.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and allows a plurality of carrier codes to be stored in a simple format, thereby improving the efficiency of memory use and improving the data processing speed. The purpose is to provide a storage method.

A method for storing a unique code of a mobile communication terminal according to the present invention for achieving the above object, in the method for storing a unique code of a mobile communication terminal in which a service provider code of a service provider is stored, is allocated for storing the service provider code. Setting a corresponding operator code in each digit of a memory unit; And storing the binary number of one of 0's and 1's in the bit unit of the provider code of the service provider according to whether the service provided by the service provider is used.

Here, the step of storing whether the service provided by the service provider is used, when allowing the use of the service, is preferably a step of storing 1 in the bit unit of the provider code of the service provider is set.

Hereinafter, a method of storing a unique code of a mobile communication terminal according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

 2 is a unique code storage state diagram of a mobile communication terminal according to the present invention. As shown in FIG. 2, the present invention sets a provider code according to each bit unit digit of a 16-bit memory in which a provider code is stored, and indicates whether the service provider uses the service using a binary number of 0 and 1.

That is, the first bit unit of the 16-bit memory storing the operator code is set as the first service provider in the first bit unit, the second service provider in the second bit unit, and the third service provider in the third bit unit. Store 1 if the service provider can use the service or 0 if the service provider does not use the service.

When storing the operator code in this way, the programming form is as follows.

<Programming Example 1>

NetworkBlockControlRegTag.status = A; // Allow

NetworkBlockControlRegTag.networkOperatorId [0] .mcc = 334; // Country Code 334

NetworkBlockControlRegTag.networkOperatorId [0] .mnc = 1; // first carrier

Programming Example 1 illustrates a case in which a country having a country code of 334 allows use of a first business operator. According to the above program, 1 is stored in the first bit unit digit of the 16-bit memory in which the operator code is stored and is stored in the form of 0000 0000 0000 0001. As such, since 1 is stored in the first bit unit position, which is the area in which the use of the first operator is stored, the corresponding terminal can use the service of the first operator.

In the case where both services of the first and second providers are allowed, the programming form is as in <Programming Example 2> below.

<Programming Example 2>

NetworkBlockControlRegTag.status = A; // Allow

NetworkBlockControlRegTag.networkOperatorId [0] .mcc = 334; // Country Code 334

NetworkBlockControlRegTag.networkOperatorId [0] .mnc = 3; // First and second carriers

In order to allow the use of both the first and second operators, 1 must be stored in the form of 0000 0000 0000 0011 in the first and second bit units of the 16-bit memory where the operator code is stored. When "3" is substituted and stored in memory, 3 is converted to binary "11 ₍₂₎ " and stored.

On the other hand, in the case of enabling the first and third operators, the programming form is as follows.

<Programming Example 3>

NetworkBlockControlRegTag.status = A; // allow

NetworkBlockControlRegTag.networkOperatorId [0] .mcc = 334; // country code334

NetworkBlockControlRegTag.networkOperatorId [0] .mnc = 5; // First and Third Operators

In order to allow the use of the first and third providers, 1 must be stored in the first bit unit and third bit unit digits of the 16-bit memory in which the operator code is stored and stored in the form of 0000 0000 0000 0101. Substitute 5 "to store 5 in binary," 101 ₍₂₎ ".

As described above, the present invention sets the provider code according to each bit unit digit of the memory allocated to store the operator code and indicates whether the service provider uses the service in binary numbers of 0 and 1, so that normally 16 bits are allocated. In the memory, all 16 service providers can use the service.

As described above, the embodiment according to the present invention is not limited to the above, and various modifications can be made within the scope apparent to those skilled in the art in connection with the present invention.

As described above, the present invention sets a provider code according to each bit unit digit of the memory allocated to store the operator code, and displays whether the service provider uses the service in binary of 0 and 1, thereby providing a plurality of operator codes. Can be stored in a simple format that not only increases the efficiency of memory usage but also speeds up data processing.
