Description

Subscriber identification card conversion system and method

The invention relates to a user identification card conversion system on a portable communication device, in particular to a user identification card conversion system with automatic discrimination and conversion functions and its method.

Subscriber Identification Module (SIM) is the only way for mobile phone users to obtain network services in Global System for Mobile (GSM). Through the SIM card, the user can become a registered user of the network and enjoy various services provided by the network. Most of the mobile phones currently on the market have a single SIM card, but many people have more than one SIM card, and often need to replace the SIM card before using it, which is quite inconvenient.

With the rapid growth of domestic mobile phone users and the rapid increase in penetration rate, more and more people have a user with more than two portable communication device user identification cards, that is, SIM cards. The solution is mostly to carry multiple mobile phones at the same time. Otherwise, there are currently mobile phone operators who provide the service of refitting the SIM card slot on the back panel of the mobile phone. However, taking multiple mobile phones at a time needs to invest a lot of money to buy mobile phones. Directly modifying the back panel of the mobile phone will cause sequelae that the original factory does not recognize it as the original product and refuses to repair it. Therefore, some operators have developed dual-card dual- The idea of the number is that the SIM card is not installed in the mobile phone, but is installed in the battery, and when the battery is powered on and off, the pulse level changes when the voltage is boosted and decompressed, and the jump between the two SIM cards is used. Therefore, when consumers need to switch from network A to network B, that is, jump to the identification card service, they must first shut down and turn on again within ten seconds, because the voltage changes will force the current to jump. To another SIM card to achieve the purpose of changing the card number, but this way of installing on the battery may cause excessive power consumption and easy to wear the surface of the SIM card, and the switching process is quite inconvenient .

The purpose of users using dual numbers is usually to manage and filter incoming calls. For example, use the number provided by the company on working days for work purposes, and use another private phone number on holidays, which is only provided to relatives and friends. Therefore, when using When the phone number is used for work, the private phone number is changed to a designated pick-up, and all callers can be connected. Only when the private call is enabled, the work call will not be answered. In addition, many mobile phones have launched "user network call "Discount" and "Monthly Call Fee Discount" measures, users can also choose different numbers and systems according to the situation when using multiple different numbers, so as to achieve the effect of saving costs.

The present invention provides a user identification card conversion system to solve the above problems, the main purpose of which is to convert the dialed and received phone numbers when the user uses a portable communication device, through the digital signal processing provided by the present invention The module automatically controls and manages to fully achieve the best benefit of using multiple subscriber identification cards.

1. The storage unit 210, which provides a temporary register to temporarily store the telephone number that the user wants to dial out in the unit, and it can be dialed out after being checked. And can store the personal identification code (Personal Identification Number; PIN) of different SIM card 150 in this storage unit by the user, just can in the process of conversion, the user needn't input this PIN code again, and only needs to call this PIN code. The storage unit will do.

2. The detection unit 220, when the phone number that the user wants to dial out and the phone number that the user wants to receive, this unit checks and judges that the phone number is consistent with the SIM card 150 in the portable communication device 100 through the data of 180 in the database. systems are compatible.

3. Conversion unit 230, this unit will not have the SIM card 150 that is compatible with this phone number to be converted to compatible SIM card 150, keep the phone number that the user wants to receive continuously in the process of conversion, make the caller needn't be called by this unit hang up.

4. The switching unit 240, which has a high priority after being switched by a hardware, and can be forcibly switched to any SIM card 150 system, instead of being switched by the above-mentioned switching unit 230.

The database 180 includes multiple columns for storing and distinguishing data of different types and formats, such as: basic information (Administrative Information), IC Card Identification (IC Card Identification), International Mobile Subscriber Identity (IMSI), Mobile phone address information (Location Information), system operation password (Ciphering Key; CK), personal identification number (Personal Identification Number; PIN) and unlock code (PIN Unlock Key; PUK) and other data. And the numbers belonging to different telecom operators can be input into the database 180 as a distinguishing standard. And because portable communication device 100 can install a plurality of SIM cards 150 at the same time, and each SIM card 150 all has the database 180 of this card, like this, just can convert through the interconnection of digital signal processing (DSP) module 200 Actions.

Fig. 2 is the flow chart of the subscriber identification card conversion system proposed by the present invention, illustrating the basic flow of the present invention's conversion subscriber identification card system, as follows:

First provide a plurality of SIM cards and install them in the portable communication device (step 300), then turn on the power and dial/receive a phone number (step 310), then call the phone number sample in the database (step 320), which is stored in the database User-defined phone number, then compare the phone number (step 330) by DSP, if the comparison result needs to be converted, then convert the SIM card (step 340), and finally end the call and stand by (step 350); if there is no need to convert , go to step 350.

Yet the present invention provides a manual contact (hardware switching), and this manual contact is a switch (Switch) and can be placed in any range on the portable communication device 100, such as: on the shell of dial button, battery, portable communication device and portable communication device body etc., when the manual contact is not turned on, the detailed flow chart of user dialing is as follows (see Figure 3):

First multiple groups of different SIM cards are loaded into the mobile phone (step 400) and turn on the mobile phone (step 402), because of turning on the power supply, so multiple groups of SIM cards are connected to the mobile phone control circuit (step 404) simultaneously, and then call DSP controls (step 406), and selects to use wherein a SIM card (step 408), when SIM card system requires input PIN code, automatically imports the PIN code of this SIM card by DSP function and standby (step 410). As mentioned above, the DSP can find the PIN code of the SIM card in the storage unit 210. When using the dial-up function and dialing out a phone number (step 412), the DSP will judge whether the system for dialing out the phone number already exists in In one of the SIM cards (step 420), if the system for dialing out the phone number already exists in one of the SIM cards, then automatically switch to the SIM card (step 422) of the system where the phone number is dialed out by DSP and pass The DSP function automatically imports the PIN code (step 424) of the SIM card after the conversion; If the system of this dialed-out phone number does not exist in one of the SIM cards, DSP then judges whether the system of the dialed-out phone number is compatible with one of the SIM cards The system has preferential measures (step 430), if there are preferential measures, then proceed to step 422; if no preferential measures, then directly dial out the phone number (step 432) from the initial SIM card, and then complete the dialing (step 440), When the call is ended and the SIM card system to be used is selected (step 450), and step 410 is repeated until the machine is turned off.

The above-mentioned preferential measures are promotional methods for different communication operators to improve their competitiveness. Users can define them in the SIM card. If operator A has discounts for dialing or receiving phone numbers of operator B, this definition will be adopted. , DSP can switch from the SIM card of operator A to the SIM card of operator B, but this discount is invalid for operator C. This function can be used according to different needs of users.

When the manual contact is turned on, the flow chart of user dialing is as follows (see Figure 4):

First multiple groups of different SIM cards are loaded into the mobile phone (step 500) and the mobile phone is turned on (step 502). Because of turning on the power supply, multiple groups of SIM cards are simultaneously connected to the mobile phone control circuit (step 504), and then call the DSP Control (step 506), when the user opens a manual contact (step 508), he chooses to switch to a specific SIM card (step 510), when the SIM card system requires input of a PIN code, the SIM card is automatically input through the DSP function PIN code and standby (step 512). As mentioned above, the DSP can find the PIN code of the SIM card in the storage unit 210. When performing the dialing function and dialing out a phone number (step 514), the dialing (step 516) is directly completed without conversion by the DSP , then end the call and select the SIM card system you want to use or shut down (step 518), if you choose to change the SIM card system, then go back to step 510; if you choose not to change the system, then go back to step 512 until the shutdown.

Another situation is when the user receives an incoming call, the flow chart is as follows (see Figure 5):

First many groups of different SIM cards are loaded into the mobile phone (step 600), and the mobile phone is turned on (step 602). Because of turning on the power supply, multiple groups of SIM cards are simultaneously connected to the mobile phone control circuit (step 604), and then Call the DSP to control (step 606), then the user chooses whether to open the manual contact (step 610), if the manual contact is selected to open, then switch to a specific SIM card (step 620), and automatically input the SIM card's ID through the DSP function PIN code and standby (step 622), when the portable communication device produces an incoming call information (step 624), directly answer the incoming call (step 650), then end the call and select the SIM card system to use or shut down (step 660), If continue standby then repeat step 622, until shutting down; If choose not to open manual contact, then select to use wherein a SIM card (step 630), and automatically input the PIN code of this SIM card by DSP function and standby (step 632 ), when generating an incoming call information (step 634), the DPS will judge whether the incoming call number is compatible with one of the SIM card systems (step 636), if the incoming call number is compatible with one of the SIM card systems, then answer the Incoming call (step 650); If the telephone number of the incoming call is not compatible with one of the SIM card systems, it is automatically converted to the compatible SIM card (step 638) of the telephone number of the incoming call, and automatically imports the SIM card after the conversion by the DSP function PIN code (step 640), then answer the incoming call (step 650), then end the call and select the SIM card system you want to use or shut down (step 660), if you want to continue standby, then repeat step 632 until shut down.

The above-mentioned SIM card systems compatible with the phone number of the incoming call refer to the same SIM card system operator and different SIM card system operators, but there are preferential measures between them, and this preferential measure is defined by the user.

However, the examples given above are not intended to limit the scope of the present invention. Anyone who is familiar with this technology can make equivalent changes and modifications without departing from the spirit and scope of the present invention, which are all rights of the present invention. covered by the scope of protection.
