BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a schematic structural diagram of a mobile communication system to which the method of the present invention is applied;

Figure 2 is a flowchart of the method of the present invention. detailed description

As shown in FIG. 1, the method of the present invention involves a mobile terminal, a core network, and an authorized receiving entity. The mobile terminal and the core network exchange messages through an air interface (also called a wireless interface). The air interface is a standard interface specified by related protocols. . The authorized receiving entity may be a mobile terminal, a computer, or a designated forwarding unit in the core network; if the authorized receiving entity is a mobile terminal or a computer, it is connected to the core network through a standard interface; if the authorized receiving entity is a designated forwarding unit , The interface with the core network is an internal interface, and is connected to the mobile terminal and the computer that are finally received through a standard interface; the personal information is formatted in a designated forwarding unit and then forwarded to the mobile terminal and the computer according to a standard protocol.

Figure 2 shows the flow of the method of the invention. When the user loses the mobile terminal, he can request the operator to back up the personal information in his mobile terminal to the designated authorized receiving entity. The authorized receiving entity can be a mobile terminal, a PC, or a forwarding unit in the mobile core network, and needs to provide relevant information to the core network, such as the International Mobile Subscriber Identity IMSI, Electronic Serial Number / International Mobile Equipment Identity ESN / IMEI, etc.

When the lost mobile terminal is powered on, the core network detects the user's mobile terminal through the unique identification of the mobile terminal, and identifies whether the current user of the mobile terminal has replaced the user identification module, such as SIM / UIM / US top card. The core network then sends a special personal information transmission instruction defined internally to the user's mobile terminal. This special personal information transmission instruction is carried by a specific short message.

When the user's mobile terminal receives the short message, it determines whether it is an ordinary short message or a special short message for personal information transmission. If it is an ordinary short message, it is processed according to the ordinary short message processing flow; if it is a special one For short messages for personal information transmission, the user's mobile terminal does not display the short messages to the user, and sends a confirmation instruction to the core network, and at the same time organizes the personal information according to the different transmission forms according to the requirements of the personal information transmission instruction, such as the information Organized into short message form, data file form Format, multimedia message format, email message format, or SyncML mode.

Then, the user's mobile terminal secretly transmits the organized personal information to the authorized receiving entity. If the authorized receiving entity is a mobile terminal or PC, the mobile terminal or PC automatically saves the personal information after receiving it; if the authorized receiving entity is a designated forwarding unit of the core network, the forwarding unit temporarily receives the personal information Save and convert it into a format that is finally received by the mobile terminal or PC, and then send it to the authorized terminal or PC through the network as required.

The above process is described in detail below. The key of the method of the present invention is that the core network sends a special personal information transmission instruction to the lost mobile terminal, and the instruction is characterized by a special short message. Table 1 is a list of the parameters carried in the short message.

Table 1 List of parameters carried in short messages

As can be seen from Table 1, when transmitting a short message, there must be an address labeling field. Therefore, the present invention uses a special address label to distinguish between an ordinary short message and a personal information transmission instruction, that is, if the content carried by the short message is a personal information transmission instruction , The special address identification agreed between the mobile terminal and the core network is used, so that when the mobile terminal receives the short message from the special address, it will process it according to the personal information transmission instruction, otherwise, it will process it according to the ordinary short message.

When the lost mobile terminal is powered on in the mobile network, the core network can detect the lost terminal through the unique identification of the terminal, and the core network sends a short message to the mobile terminal with a personal information transmission instruction from a special address, and the personal information is transmitted The content of the instruction includes an indication of the lost terminal, an indication of the transmission method, an indication of the content of the transmission (whether it contains personal information in the user identification module), and so on.

After receiving the short message, the mobile terminal judges the address parameter by detecting the address parameter, that is, the start address of the short message. Whether the short message is a special short message carrying personal information processing instructions. If yes, the personal information is sorted according to the transmission mode instruction. If the transmission content instruction includes the personal information in the user identification module, the personal information in the user identification module is sorted at the same time. If the transmission method is to send in the form of a short message, the personal information is organized into multiple short messages; if the transmission method is to be sent through a data service in the form of a data file, the personal information is organized into a data file; if the transmission method is to be a multimedia message If it is sent in the form, the personal information is organized into multimedia messages; if the transmission method is sent by email, the personal information is organized into e-mail; if the transmission method is sent in SyncML, the personal information is organized into SyncML. The transmission method can be negotiated or specified according to the support capabilities of the mobile terminal and the core network. The organized personal information is then secretly sent to the designated authorized receiving entity.

No matter which of the above-mentioned methods is used for the transmission of personal information, when the mobile terminal sends personal information, no prompt is given to the current user to prevent the mobile terminal from maliciously terminating when the mobile terminal indicates that it is a lost terminal. Moreover, when the current user performs a shutdown operation during the transmission of personal information, the mobile terminal can only turn off external circuits, such as the display LCD, speaker Speaker, microphone MIC, keyboard, and various service indicators, causing a false shutdown. Phenomenon, wait until the personal information is transmitted and then completely shut down.

In addition, if the mobile terminal indicates that it is a lost mobile terminal, after the mobile terminal finishes transmitting the personal information, it starts a self-destructing program to delete the personal information of the lost mobile terminal. Further, a power-on password protection function is enabled, and a random password is set to prevent the lost mobile terminal from being used again.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technology of the present invention can be Modifications or equivalent replacements of the solutions without departing from the spirit and scope of the technical solutions of the present invention should be covered by the claims of the present invention.
