technical field

The invention relates to the field of mobile communication, in particular to a method for backing up lost personal information in a mobile terminal in a mobile communication system.

Background technique

Most of the existing mobile communication terminal devices provide storage space for important user sensitive information such as phone book and work schedule, and this storage space has been used by most users. As the storage space in the mobile terminal becomes larger and larger, more and more information is stored inside. Once the user's mobile terminal is lost, if the personal information cannot be rescued and backed up, it may cause a very large information loss to the user. No solution has been found in the prior art for backing up the personal information in the lost mobile terminal.

Contents of the invention

The technical problem to be solved by the present invention is to propose a method for backing up personal information in a lost mobile terminal in a mobile communication system.

The present invention completes the backup of the personal information in the lost mobile terminal through the following steps:

1.1 Set up an authorized receiving entity;

1.2 When the user reports the loss and registers, he requests the operator to back up the personal information in his mobile terminal to the authorized receiving entity;

1.3 After the core network detects the user's mobile terminal through the mobile terminal identification, it sends an internally defined special personal information transmission instruction to the user's mobile terminal;

1.4 After receiving the above instructions, the mobile terminal of the user sends a verification instruction to the core network, and organizes information according to the instructions of the core network;

1.5 The user's mobile terminal secretly transmits the sorted personal information to the authorized receiving entity;

1.6 Authorize the receiving entity to store personal information received.

In the above solution, the receiving entity may be another mobile terminal or PC, and exchange messages with the core network through a standard interface protocol. The receiving entity can also be a designated forwarding unit in the network; if it is a designated forwarding unit in the network, step 1.6 includes: the designated forwarding unit temporarily saves the personal information after receiving it, and converts it into a format supported by the mobile terminal or PC , and then send it to the authorized terminal or PC through the network as required.

The core network in the above step 1.3 sends transmission instructions to the mobile terminal of the user, which is realized by adopting a special short message with a special address agreed between the mobile terminal of the user and the core network.

The user's mobile terminal in the above step 1.4 organizes the information according to the instruction of the transmission mode and organizes the information into short messages, data files, multimedia messages, email messages or SyncML.

In the technical solution of the present invention, after the user's mobile terminal transmits personal information, it can also start a self-destruct program to delete the personal information in the user's mobile terminal. And after deleting the personal information, start the power-on password protection program again, set a random password, so that the lost mobile terminal cannot be used again.

By adopting the method of the present invention, the personal information in the lost mobile terminal can be backed up conveniently through certain operations in various existing mobile communication systems, which brings great convenience to users.

Detailed ways

The present invention relates to a lost mobile terminal, a network, and an authorized receiving entity. The relationship among these three can be shown in FIG. 1 . The interface relationship between the three is described as follows:

1. The interface between the mobile terminal and the core network is called the air interface, also called the wireless interface, which is a standard interface stipulated by relevant protocols, and they exchange messages according to the standard wireless interface protocol;

2. The authorized receiving entity can be a mobile terminal, a computer, or a designated forwarding unit in the network; if the authorized receiving entity is a designated forwarding unit, the personal information will be format-converted by the designated forwarding unit, and then forwarded to the mobile terminal according to the standard protocol , computer, the interface between it and the core network is also an internal interface, and the standard interface is between the designated forwarding unit and the mobile terminal and computer; if the authorized receiving entity is a mobile terminal or computer, then it is a standard interface between it and the core network interface.

The process of the present invention can refer to Fig. 2:

1. Set up an authorized receiving entity, and provide relevant certificates and information, such as IMSI, ESN/IMEI, etc. The authorized receiving entity may be a mobile terminal, a PC, or a forwarding entity unit in the operator's network.

2. After the user loses the mobile terminal, when applying for loss report registration, the user requests the operator to back up the personal information in his mobile terminal to the authorized receiving entity;

3. When the mobile terminal is in the power-on state, the core network can also identify whether the current user of the mobile terminal has changed the user identification module (such as SIM/UIM/USIM card, etc.) after detecting the user's mobile terminal through the unique identifier of the mobile terminal. ), the core network sends internally defined special personal information transmission instructions to the mobile terminal of the user. This transmission instruction can be realized with a specific short message.

4. After receiving the short message, the mobile terminal of the user judges whether it is a common short message or a special short message. If it is an ordinary short message, it is processed as an ordinary short message. If it is a special short message, a confirmation instruction is sent to the core network, but it is not displayed to the user. At the same time, according to the instruction requirements, the personal information will be organized according to different transmission forms (short message, data file form, multimedia message form, email message form or SyncML form, etc.).

5. The user's mobile terminal secretly transmits the sorted personal information to the authorized receiving entity; if the authorized receiving entity is a mobile terminal, the personal information is received and stored automatically; if the authorized receiving entity is a core network forwarding entity unit, It can be temporarily saved and converted into a format supported by the mobile terminal or PC, and then sent to the authorized terminal or PC via the network as required.

Some contents in the above process will be described in detail below.

The personal information transmission instruction to the mobile terminal can be characterized by a special short message, which requires the modification of the short message structure. Table 1 is a partial list of parameters carried by the short message.

Table 1 Short message carrying parameter list parameter type initial address A mandatory item for the mobile terminal call-out message, and an optional item for the mobile terminal call-out message Destination address A mandatory item for the mobile terminal call message, and an optional item for the mobile terminal call final message

The structure of the above parameters shows that when sending a short message, there must be an address label field, so the present invention decides to use a special address label to distinguish whether it is an ordinary short message or a personal information transmission instruction, that is, if the content carried in the short message is personal information transmission Instructions are marked with the special address agreed between the mobile terminal and the core network, so that when the mobile terminal receives a short message from a special address, it can be used as a personal information transmission command; otherwise, it is treated as a normal short message.

When the mobile terminal is turned on in the mobile network, the core network can detect the existence of the lost terminal through the unique identification of the terminal, and the network sends an internally defined special instruction to the mobile terminal—personal information transmission instruction. Address specific short message realization, short message content should include lost terminal indication, transmission mode indication, transmission content indication (whether personal information in the card is included), etc.

After the mobile terminal receives the short message sent to itself, it first checks the address parameter (the start address of the short message) to determine whether it is a personal information processing instruction. If so, it sorts out the personal information according to the transmission mode instruction. If the information in the card is included in the transmission content instruction, the personal information in the card will also be sorted out. If it is sent in the form of a short message to an authorized receiving entity, it will be organized into multiple short messages; if it is sent in the form of a data file, it will be organized into a data file and sent through data services; if it is sent in the form of a multimedia message, it will be organized into a multimedia message Message sending; if it is sent by e-mail, it will be sent as a multimedia message, and if it is sent in SyncML, it will be sent in SyncML. The transmission mode can be negotiated or specified according to the support capabilities of the mobile terminal and the network.

Whether sending personal information in the form of a short message or in other ways, the mobile terminal does not give any prompts to the user when sending the personal information, so as to prevent the mobile terminal from being maliciously terminated by the current user when the mobile terminal indicates that it is a lost terminal. Moreover, when the current user performs a power-off operation during the personal information transmission process, the mobile terminal can only turn off external circuits (such as LCD, Speaker, MIC, keyboard, various service indicator lights, etc.), resulting in a false power-off phenomenon that confuses the current user. Users, wait until the transfer of personal information is complete before shutting down completely.

In addition, when the mobile terminal indicates that it is a lost terminal, the mobile terminal can start a self-destruct program after the transmission of its personal information is completed, delete the personal information of the lost mobile terminal, and then enable the power-on password protection function and set a random password , so the lost mobile terminal can no longer be used.

It can be seen from the above description that the present invention has a wide range of applications, and it can be applied to various existing mobile communication systems. The implementation of the present invention does not require major changes to the network system. On the basis of the existing protocol, by slightly changing the short message processing flow of the mobile terminal, the individual in the mobile terminal can be Information, very convenient rescue and backup. Backing up the personal information in the lost mobile terminal not only brings great convenience to the user, but also protects the user's personal privacy to a certain extent. By activating the password protection program for the lost mobile terminal, it brings obstacles to the reuse of the lost mobile terminal, thereby also reducing the loss rate of the mobile terminal to a certain extent.
