Method for realizing multiple user identities of wireless terminal

technical field

The invention relates to a wireless terminal user identification in wireless communication, in particular to a method for realizing multiple user identifications of a wireless terminal.

Background technique

Currently used wireless terminals (such as mobile phones, PDA (Personal Data Assistant, Personal Digital Assistant)) widely adopt the one-machine-one-card technology, and the one-machine-one-card technology means that a wireless terminal only uses one user identification card, and the user identification The card is used to store user identification information, such as IMSI (International Mobile Subscriber Identity, International Mobile Subscriber Identity) number, system identification code, network identification code, preferred frequency point list, operator name, etc. Existing subscriber identification cards include those used in GSM (Global System for Mobile communications)/GPRS (General Packet Radio Service)/WCDMA (Wideband Code Division Multiple Access) wireless terminals. SIM (Subscriber Identity Module) card, UIM (User Identity Module) card used in CDMA (Code Division Multiple Access)/CDMA1X wireless terminals.

In practical applications, some operators require network users to use "external user identification cards", that is, to adopt the machine-card separation technology in the field of wireless communication: the user identification information is stored in the SIM/UIM card, and the wireless terminal only needs to insert Only after the SIM/UIM card can it be used normally; while some other operators require network users to use the "built-in user identification card", that is, to adopt the machine-card non-separation technology in the field of wireless communication: refers to the user identification information written on the wireless terminal Fixed storage area, wireless terminal does not need to connect SIM/UIM card.

Since different operators may use different technologies for network communication, it is difficult for users to flexibly choose the operator's network. Temporarily use the network of another operator, and it happens that the other operator only supports the technical solution of "no separation of machine and card", then these users will inevitably purchase another wireless terminal, resulting in unnecessary waste of resources.

In addition, with the increasing number of network standards, many dual-mode wireless terminals or multi-mode wireless terminals have appeared, such as dual-mode wireless terminals supporting GSM/CDMA, PHS (Personal Handyphone System, personal portable phone system)/GSM dual-mode wireless terminals Terminals, etc. These dual-mode or multi-mode wireless terminals may be required to support two or more sets of subscriber identification cards at the same time.

In order to make a wireless terminal applicable to different operator networks and have two or more working modes, some manufacturers have introduced the "one machine with two cards" or "one machine with multiple cards" technical solutions. The solution adds one or more card reading devices to a common wireless terminal that supports an external user identification card. For example, 'Wantong Card', the card includes an analog switch and a dual-card device, which uses an analog switch to control switching between two SIM/UIMs. On this basis, some companies have improved this technology, for example: cut two SIM/UIM cards, separate the core part, install it on a PCB board, and integrate it into one card.

In the prior art, whether by modifying the structure of the wireless terminal, adding a card reading device on the main board of the wireless terminal, or integrating several cards together, it is actually one machine with two cards or one machine with multiple cards. Therefore, the circuit structure of the wireless terminal must be modified, and two or more external user identification cards are required to realize double numbers or multiple numbers in one machine, and it cannot be used without modifying the circuit structure of the wireless terminal. A wireless terminal realizes the multi-number function.

Detailed ways

The present invention actually adds one or more built-in user identification information on the basis of the wireless terminal using external user identification information, and the user can select the user identification information to be used through the menu of the wireless terminal without changing the structure of the wireless terminal. In this case, one wireless terminal has multiple numbers. The specific method of the present invention is shown in Figure 1, comprising: step s101, select to use external user identification information or built-in user identification information; step s102, save the result of the selected user identification information; step s103, start the wireless terminal; step s104, Judging the type of user identification information selected, if it is external user identification information, then execute step s105, read the external user identification from the external user identification information memory (such as in the external user identification card) of the wireless terminal information; if it is built-in user identification information, execute step s106, read the built-in user identification information from the internal memory of the wireless terminal; step s107, perform network search and registration according to the read user identification information.

The technical scheme of the invention can be applied to all wireless terminals using SIM/UIM cards, including mobile phones, PDAs and the like. The mobile phone is taken as an example below, and the specific implementation manner is described in conjunction with the accompanying drawings.

The present invention combines the traditional machine-card separation technical solution with the machine-card non-separation technical solution, so that the mobile phone can not only use an external user identification information for wireless communication, but also use one or more built-in user identification information for wireless communication . When the user uses the external user identification information, it can be read from the external user identification card by the card reading device on the mobile phone; when the user uses the built-in user identification information, it can be read from the internal memory of the mobile phone. The built-in user identification information can be directly written into the internal memory of the mobile phone by the manufacturer through a communication interface such as a serial port, a USB port, or an infrared port. When the internal storage of the mobile phone is a flash memory or an electrically erasable memory, the built-in user identification information can be modified; and When the internal memory of the mobile phone is a read-only memory, the built-in user identification information cannot be modified.

For mobile phones with the above functions, user identification information can be selected through the mobile phone settings menu. As shown in Figure 2: first on the setting menu 201 of the mobile phone, a 'user identification information' option has been added, for example, only 'voice' and 'sound' are included in the original setting menu option, and the revised setting menu 201 includes ' Speech', 'Sound' and 'User Identification Information'. After the user selects 'user identification information' and confirms, he will enter the user identification information submenu 202, which includes 'external identification information', 'built-in user identification information' and 'default' options in the user identification information submenu 202. When the user selects the 'built-in user identification information' option, it means to use the built-in user identification information for wireless communication; when the user selects the 'external identification information' option, it means to use the external identification information for wireless communication; Set identification information (also can be set as built-in user identification information) for wireless communication, this function is realized by the program inside the mobile phone.

When the user's settings are completed, the mobile phone needs to save the user's selection result (using the built-in user identification information or external user identification information) to a fixed address in the internal memory of the mobile phone, the purpose of which is to ensure that the information will not be switched on and off again and lost. For example: the data written in the fixed address is "0" by default; if the user selects "external user identification information", write the data "1" into the fixed address; if the user selects "built-in user identification information ", then the fixed address will be written into the data "2"; if the user selects "Default", the software will write the fixed address into the data "0".

After saving the result selected by the user, the mobile phone needs to be restarted to make the result selected by the user take effect. The mobile phone must use the user identification information selected by the user to search the network again. For example, if the user selects the built-in user identification information, and the operator of the built-in user identification information is China Mobile, then it needs to search the China Mobile network to communicate normally.

The startup of the mobile phone generally goes through the following process, as shown in Figure 3:

Step s301, choose to use external user identification information or built-in user identification information;

Step s302, saving the result of the selected user identification information;

Step s303, the mobile phone starts;

Step s304, judging whether the user uses external user identification information or internal user identification information, this step is determined by reading the selection result stored in the fixed address of the internal memory of the mobile phone. If the user selects the built-in user identification information, then execute step s305 to read the built-in user identification information from the internal memory of the mobile phone; then perform step s307 to judge whether the read built-in user identification information is valid (the criterion for judging is the user identification length of the IMSI in the message), when the length of the read IMSI is equal to the length of the standard IMSI, it means that the transmission process is normal, and then step s309 is executed, and the built-in user identification information is used for network search and registration; when the read IMSI When the length of the standard IMSI is not equal to the length of the standard IMSI, it means that there is an error in the transmission process. Step s310 is executed to directly enter the standby state and a prompt message is given.

In the same way, if the user selects the external user identification information, then execute step s306 to read the external user identification information from the external memory of the mobile phone; then perform step s308 to judge whether the read external user identification information is valid ( The criterion for judging is the length of the IMSI in the user identification information), when the length of the IMSI read is equal to the length of the standard IMSI, it means that the transmission process is normal, and then step s309 is executed, using the external user identification information for network search and Registration, when the length of the read IMSI is not equal to the length of the standard IMSI, it means that there is an error in the transmission process, execute step s310, directly enter the standby state, and give a prompt message.

When the above-mentioned transmission is wrong, the purpose of directly entering the standby state is to prevent the user from failing to start the mobile phone normally due to wrong settings, and cannot modify the setting items again, which will form an endless loop. For example, a user selects "external user identification information" in the setting menu, but in fact the user intends to use "built-in user identification information", and "external user identification information" does not exist at all; After restarting, the "external user identification information" will not be read; at this time, it is necessary to provide this kind of error prevention means so that the user can enter the setting menu of the mobile phone again, and modify the setting item to "built-in user identification information", only Only in this way can the user be able to use the mobile phone normally.

Another embodiment of the method for realizing multiple user identities of a wireless terminal in the present invention realizes one machine, one card and dual modes.

When the user's mobile phone is single-mode, the present invention can only realize multiple numbers of different operator networks under the same mode, and when the user's mobile phone is dual-mode, the present invention can realize one machine with dual modes. For example, the built-in user identification information is a GSM mode, and the external user identification information is a CDMA mode. When the user selects the built-in user identification information through the mobile phone menu, its working mode is GSM. The mobile phone uses this information to search the network. When it finds the GSM network it belongs to, it sends registration information to the GSM network. After the communication channel is established, it enters the standby mode. state. vice versa.

Another embodiment of the method for realizing multiple user identities of a wireless terminal in the present invention is one machine with multiple numbers.

First, write multiple built-in user identification information in the internal memory of the mobile phone, such as built-in user identification information 1, built-in user identification information 2, built-in user identification information 3, until built-in user identification information n; the user selects the user through the modified setting menu Identification information. As shown in Figure 4, when the user selects user identification information in the mobile phone setting menu 401, an external user identification information option and multiple built-in user identification information options will appear in the user identification information 402, and the user can choose one of them arbitrarily. One, and use this information to conduct web searches and web registrations.

The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, and these improvements and modifications should also be It is regarded as the protection scope of the present invention.
