Description

512617 V. Description of the Invention (1) [Field of the Invention] The present invention relates to a user identification card on a portable communication device, and particularly to a user identification card conversion system with automatic identification and conversion. [Background of the Invention] The Subscriber Identification Module (SIM) is the only way for mobile phone users to obtain network services in the Global Mobile Communication System (G10b a 1 S s tem f om Mobile; GSM) system. Through the SIM card, users can become registered users of the network and enjoy various services provided by the network. At present, most of the mobile phones on the market are single SIM cards, but many people have more than one SIM Card. It is inconvenient for the owner to change the card before using it. With more than 12 million mobile phone users in China, the penetration rate exceeds 50%. 'A user has more than two portable communication device user identification cards at the same time, that is, more and more people are SIMC ard. The solution of the "Doka family" at this stage is to carry multiple mobile phones at the same time, or else, there are also mobile phone operators who provide services to modify the SIM card slot on the back panel of the mobile phone. However, if you need to buy a large mobile phone to buy multiple mobile phones at one time, and directly modify the back panel of the mobile phone, it will cause the original factory to not recognize the sequela of refusal to repair the original product. Therefore, some developers have developed dual-card dual-door numbers. The idea is that the SIM Card is not installed on the mobile phone, but is installed on the battery. When the battery is powered on and off, the principle of voltage boost and decompression pulses is used to jump between the two SIM cards. , When consumers need to switch from 曱 network to 网路 network, that is, skip the identification card service,

512617 V. Description of the invention (2) The power must be turned off first, and then turned on within ten seconds, because the voltage changes, it will force the current to jump to another SIMC ard to achieve the purpose of changing the card and number. However, this method of mounting on the battery may cause excessive power consumption and easy to wear the surface of the SIMC ard, and it is quite inconvenient during the switching process. The purpose of the user to use the double door number is usually to manage and filter incoming calls. For example, on the working day, the door number provided by the company is used for work purposes. On holiday, another private phone number is used only for friends and relatives. Therefore, When using a work phone number, the private phone number is changed to a designated call, and all callers can connect. Only when the private phone is enabled, the work phone is not answered. In addition, many mobile phones have launched the "user network" "Internal discount", "monthly call fee discount" measures, using multiple different door numbers, users can also choose different door numbers and systems depending on the situation, to achieve the effect of saving costs. [Summary and purpose of the invention] In view of this, the present invention is to provide a user identification card conversion system in order to solve the above-mentioned problems. The main purpose is to perform dialing and receiving phone numbers when a user uses a portable communication device. The conversion function is automatically controlled by the digital signal processing module provided by the present invention, and the best benefit of using a plurality of user identification cards is fully achieved.

When the SIM card system requires the PIN code to be entered, pass DS The P function automatically enters the PIN code of the SI Μ card and waits (step 4 1 0). As described above, the DSP can find the PIN code of the SI Μ card in the memory unit 2 10. When a phone number is issued (step 4 1 2), the DSP will determine whether the system of the outgoing phone number already exists in one of the SIM cards (step 4 2 0). If it exists in one of the SIM cards, it will be automatically converted to the SIM card of the system to which the outgoing phone number belongs through DS P (step 4 2) and the converted DS IP card's PI I Ν code will be automatically entered through the DS PP function. (Step 4 2 4); If the system of the outgoing phone number does not exist in one of the SIM cards, DS P judges whether the system of the outgoing phone number has a preferential measure with one of the SIM cards system (step 4 3 0), if there are preferential measures, go to step 4 2 2; if there are no preferential measures, Dial out the phone number directly from the initial SIM card (step 4 3 2), and then complete the dialing (step 4 40). When the call is ended and select the SI SIM card system to be used (step 4 50), and Repeat step 4 1 0 to continue standby until shut down. The above-mentioned preferential measures are the lock-up methods for different telecommunications operators to improve their competitiveness. Users can define in the SIM card themselves. If operator A has a preferential number for dialing or receiving the telephone number of operator B, then use this definition. The DSP can switch from the SIM card of the A supplier to the SIM card of the B supplier, but this offer is not valid for the C supplier. This function can be based on different needs of users. When the manual contact is turned on, the flow chart of dialing by the user is as follows (see Figure 4): First, load the SIM card with different complex array into the mobile phone (step 5 0 0) and
