Description

System and method for automatically storing communication list of communication terminal

The present invention relates to a communication terminal, and more particularly, to a communication list automatic backup system and method in a communication terminal.

When using a communication terminal such as a mobile phone, the battery often runs out during a call with the other party. As such, when the battery runs out during a call, there has been no way of contacting the call partner again. This may not only be the case when the battery runs out during the call, and even if it is necessary to contact a specific party in a state where the user cannot use his terminal due to the exhausted battery.

In this case, if you think about the most possible scenario, there is a way to get in touch with someone else's phone. However, the method of contacting someone by borrowing a phone of a neighboring person in this way is also possible when at least the phone number of the other party can be directly remembered or the other party's telephone number can be found. In the modern age of communication civilization, most ordinary people store almost all the information (phone numbers, email addresses, their affiliations, birthdays, and other details) about their surroundings and store them on their phones whenever they need them. It is rare to find and use information about each person or to write down information about each person. In this situation, even if you can borrow someone else's phone, there is no way to contact the other party until you recharge your cell phone.

However, in the future communication technology from WCDMA to unlock USIM, personal information chips (i.e., smart cards equipped with subscriber identity modules such as SIM and USIM, and USIM cards will be described in the present specification). The terminal exists as an independent entity. Therefore, when the USIM card and the like mounted on the terminal is pulled out and used in another terminal, the billing is also made to the actual user himself. This method of use can be easily accessed when the battery of the terminal is dropped. However, in most cases, the user stores the other party's contact and address book only in the terminal (the default setting of the current terminal is the same as well), and in the case of the "recent call list", there is no format for storing in the USIM card yet.

Therefore, the user uses the user interface (UI) as shown in FIG. 4 or the UI as shown in FIG. 5 provided in the communication terminal, and the phone number (or entire phone book, recent call list, etc.) stored in the terminal itself. Does not directly store (or copy, move) the USIM card, or save the phone number in the first place, unless you store the USIM card, not the terminal, even if you pull out the USIM card to another person's terminal, Usability of the USIM card as a solution to the solution is bound to fall.

For the same reason as above, there is an urgent need for a method and technology that can further increase the usability of the USIM card in case the user's terminal is turned off and cannot be used in an unexpected situation.

The present invention is to back up the communication list information necessary for the user from the communication terminal to the smart card (for example, USIM card, etc.), in case the user of the communication terminal is turned off in an unexpected situation, The present invention provides a technique of utilizing the mobility of the smart card to check the communication list information through other terminals and to continuously use the smart card.

Other objects of the present invention will be readily understood through the following description.

According to an aspect of the present invention, a system for automatically backing up a communication list in a communication terminal equipped with a smart card equipped with a subscriber identification module is provided.

Automatic communication list backup system according to an embodiment of the present invention, the remaining amount confirmation unit for checking the remaining battery level of the communication terminal; An extraction unit for extracting communication list information meeting a preset rule from among communication records stored in the communication terminal when the remaining battery amount confirmed by the remaining amount checking unit is less than or equal to a preset threshold; And a backup unit for automatically backing up the communication list information corresponding to the preset rule extracted from the extraction unit to the smart card.

According to another aspect of the present invention, there is provided a method for a communication terminal to automatically back up a communication list with a smart card mounted on the communication terminal, where the smart card is equipped with a subscriber identification module.

The automatic communication list backup method according to an embodiment of the present invention includes the steps of checking the battery level of the communication terminal; Extracting communication list information meeting a preset rule from among communication records stored in the communication terminal when the battery level is less than or equal to a preset threshold; And automatically backing up the extracted communication list information to the smart card.

According to the system and method for automatically backing up the communication list according to an embodiment of the present invention, even when the power of the communication terminal is turned off in an unexpected situation, the smart card (for example, USIM card, etc.) By using the communication list information automatically backed up), it is possible to check the communication list information through other terminals and to continue using it.

In addition, the automatic communication list backup system and method according to an embodiment of the present invention is to ensure that the communication list information from the communication terminal to the smart card only at the time of automatic termination due to battery exhaustion, thereby preventing unauthorized leakage of the communication list information of the user It can be effective.

Hereinafter, a communication list backup system and method according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, when it is determined that the detailed description of the related known technology may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted. Numbers (eg, first, second, etc.) used in the description of the present specification are merely identification symbols for sequentially distinguishing identical or similar entities.

Through the present specification, the communication terminal is mainly assumed to be the case of a mobile communication terminal such as a mobile phone, but is not limited thereto, and any terminal having a communication function may of course correspond to this.

However, in the present specification, a communication terminal includes an entity that is independent of the terminal, that is, a smart card such as SIM, USIM, etc. is mounted on the communication terminal (ie, inserted into the corresponding slot of the terminal) so that subscriber identification / authentication is performed. Of course it must be done. In order to clearly show this, in FIG. 1, the communication terminal 10 and the USIM card 20 are separately shown as separate blocks.

1 is a block diagram showing the configuration of an automatic communication list backup system according to an embodiment of the present invention. The communication list backup system 100 of the present invention provides information about a specific communication list required by a user among various communication records stored in the communication terminal 10 in case of emergency (that is, when the communication terminal is automatically terminated due to battery exhaustion). In order to perform the function of automatically backing up to the USIM card 20, it is implemented in the communication terminal 10.

Referring to FIG. 1, the communication list backup system 100 according to an embodiment of the present invention includes a remaining amount checking unit 110, a backup unit 120, and an extracting unit 130. Here, the remaining amount check unit 110, the backup unit 120, the extraction unit 130 constituting the communication list backup system 100 of the present invention is not necessarily implemented in hardware, part or all of the software It is obvious that the implementation may be performed by the respective functions corresponding to the corresponding components.

Hereinafter, the function of each component constituting the communication list backup system 100 according to an embodiment of the present invention will be described, but with reference to the block diagram of FIG. Explain. 2 is a flowchart illustrating an example of an automatic backup method of a communication list through the communication list backup system 100 according to the present invention.

Communication list automatic backup system and method in the communication terminal of the present invention, by utilizing the USIM card unlock (unlock), even when the user runs out of the battery in the communication terminal by inserting the USIM card to another terminal, We want to increase the user's convenience by allowing to continue the call (both outgoing / incoming) possible.

According to the present invention, when the remaining battery level of the communication terminal is checked and the remaining battery level is low (that is, when the remaining battery level is enough to transfer the specific communication list information required by the user to the USIM card), It proposes a method of automatically backing up the specific communication list information required by a user to a USIM card.

As a method for enabling this, a method such as the flowchart of FIG. 2 to be described below may be used.

That is, the communication list backup system 100 of the present invention first checks the battery level of the communication terminal 10. The battery remaining amount check is performed by the remaining amount checking unit 110, and the remaining amount checking unit 110 checks to what extent the remaining amount of the battery 50 remains at any time or for a predetermined time (Fig. 2). See S210).

However, here, the confirmation of the remaining battery level through the remaining amount checking unit 110 does not necessarily need to be based on an active method as described above, and of course, the manual method may be confirmed. That is, the communication terminal 10 pre-defines (for example, a power sequence, etc.) a procedure when the battery is exhausted and the terminal is automatically terminated through the internal system standard. The check unit 110 may indirectly (passively) check the remaining amount of the battery 50 in this way. This will be more clearly understood through the description of the flowchart of FIG. 3 to be described later.

Subsequently, when the remaining battery amount checked from the remaining amount checking unit 110 is less than or equal to a preset threshold (see S220 of FIG. 2), the extracting unit 130 extracts communication list information corresponding to a specific rule among communication records stored in the communication terminal. (See S230 of FIG. 2). The communication list information thus extracted will be automatically backed up from the communication terminal 10 to the USIM card 20 by the backup unit 120 (see S240 of FIG. 2).

Here, the preset threshold may be set to the remaining battery capacity when the battery of the communication terminal has a low value and is about to turn off immediately, or if the communication terminal is likely to be turned off in a short time. That is, the threshold may be determined differently according to a predefined standard in the terminal or according to a user's setting.

However, there are two considerations here. First, the threshold to be preset should have a value greater than at least the amount of battery required to back up the call list information in the communication terminal to the USIM card. However, since the minimum battery amount required for the backup will increase in proportion to the amount of information to be backed up, the threshold will vary depending on how the number of information to be backed up is set. Second, in consideration of a security problem, the predetermined threshold is preferably set to the remaining battery level at the start time at which the communication terminal performs an automatic shutdown process by running out of battery. This is to prevent the leakage of information related to the user's personal identity by malicious third parties, which will be more clearly understood through later explanation.

In general, the extraction unit 130 will start to extract the communication list information on the basis of the time when the identified battery level becomes equal to the threshold set as described above, but the battery amount of the communication terminal 10 is suddenly changed due to sudden change. In the case where it arrives immediately below the set threshold value, the communication list information will be extracted from the point of time when it is confirmed.

In this case, the communication record includes all types of information recorded / stored through a specific storage space (see the storage unit 70 of FIG. 1) in the communication terminal 10. For example, the communication record may include an outgoing call log, an incoming call log, an missed call log, and the like, where the call log is used in all communication processes using a communication terminal, such as a voice call, a video call, and data communication on behalf of SMS. Means log information related to the recorded communication counterpart.

As described above, the extraction unit 130 performs a function of extracting only the communication list information that satisfies a predetermined specific rule among the communication records stored in the communication terminal when the remaining battery level is less than the preset threshold. Here, the predetermined specific rule may be a rule that is systematically predefined in the communication terminal 10, or may be a rule set according to a user's selection.

In this case, the preset rule is, when sorting the communication records stored in the communication terminal in the order of the latest record, the communication list information of a predetermined number (for example, about 10 recent call list order) in that order It may be defined as. In this case, even if the power of the communication terminal is automatically shut down due to the exhaustion of the battery during the call, the user can make a call with the other party through the other terminal by using the communication list information regarding the recent communication record backed up in the USIM card later. You will be able to continue.

As another example, the preset rule may be defined as a predetermined number of communication list information in that order when the communication records stored in the communication terminal are sorted in order of the other party (or telephone number) having the highest frequency of communication. This means that if the user who cannot use his or her communication terminal due to battery exhaustion attempts to make a call by moving the USIM card to another terminal, the other party is more likely to have a higher communication frequency based on the existing communication history. Considered example.

The preset rule may also include a type of communication record. That is, for example, whether to target only a received call as the communication list information to be extracted or to target all the communication records regardless of this.

In the present invention, the backup of the communication list information to the USIM card through the backup unit 120 may be set to be executed only when the communication terminal 10 is automatically terminated by the exhausted battery. This is for security reasons to prevent private information related to the personal information of the user (ie, owner) of the communication terminal from being leaked to the malicious person.

Even if the communication terminal is automatically shut down due to battery exhaustion (for example, when the terminal is manually shut down by pressing the 'end button' to turn off the power or forcibly removing the battery). When certain communication list information stored in the backup is backed up to the USIM card, an undesirable case may occur. When only the remaining battery level in which the communication list information can be backed up to the USIM card is left, a malicious user may leak the information that the user does not want if the user manually shuts down the mobile phone which is almost turned off. Because.

In order to prevent the above case, when the communication terminal is manually terminated, the automatic backup function to the USIM card as in the present invention is not supported, and the automatic backup function to the USIM card can be executed only when the automatic termination is performed. Should be For this purpose, it is preferable that the time point at which the communication list information is actually backed up to the USIM card is executed in accordance with the time point at which the communication terminal is automatically terminated by the exhausted battery. That is, the backup of the communication list information through the backup unit 120 is preferably performed at a point in time during which the automatic termination process of the power in the communication terminal 10 is in progress.

The automatic power off process at the communication terminal is performed in such a way that, for example, the LCD screen, which consumes the most battery, is turned off first, and then internal components (RF stage, processor, memory, etc.) are sequentially turned off in a predetermined order. An example is the actual backup at a point in time.

In this case, since the communication terminal is already in the process of automatically shutting down the power, it is possible to prevent a large part of the leakage of personal information of the user by a malicious third party without the user knowing. .

In addition, the security maintenance method for preventing information leakage includes the automatic backup function of the communication list to the USIM card according to the present invention so that the user can turn on / off (ie, function activation / deactivation) through a specific UI provided in the communication terminal. There is something to do. That is, a user who has a reason for not leaking information at the source should have a right to not use the automatic backup function of the present invention under his own choice. However, this is a distance from the core content of the present invention, further description will be omitted.

In the present invention, the backup of the communication list information through the backup unit 120 may be used in a manner similar to that of the UI in FIG. 4 and FIG. 5 described above (that is, calling and storing the USIM storage API). . In addition, the method of storing in the USIM card may be similar to the method of storing the USIM phonebook, and may be generated by replacing the name with the time when the collogue is left and storing the telephone number as a pair. In addition, similar to the UI item of FIG. 4, a name, a phone number, an email, and the like may also be stored. However, the storage method is a matter that can be variously modified according to the type of the terminal and the storage method thereof, and a description of the specific storage method will be omitted.

Although the communication list backup system and method according to an embodiment of the present invention have been described with reference to the flowchart of FIG. 2, in another embodiment of the present invention, the communication list backup system is transferred to a USIM card according to the flowchart shown in FIG. 3. You can also perform automatic backups.

Referring to FIG. 3, step S320 and step S330 are the same as step S230 and step S240 of FIG. 2, respectively, and only step S210 and step S220 of FIG. 2 are replaced by step S310 in FIG. 3. The flowchart is not automatically backed up according to the principle different from that of FIG. That is, in FIG. 3, the battery remaining amount checking process by the remaining amount checking unit 110 is not actively performed as shown in FIG. 2 (that is, the battery 50 is directly checked from the battery 50). It is merely a flowchart showing a case in which a passive method of confirming that the battery remaining amount of the communication terminal at the start time (see S310 of FIG. 3) is regarded as a preset threshold in step S220 of FIG. 2 is merely shown.

As described above, according to the automatic communication list backup system and method according to an embodiment of the present invention, even when the power of the communication terminal is turned off in unforeseen circumstances, a smart card (for example, (USIM card, etc.) using the communication list information automatically backed up, there is an advantage that can be used continuously to check the communication list information through the other terminal.

In addition, the automatic communication list backup system and method according to an embodiment of the present invention is to ensure that the communication list information from the communication terminal to the smart card only at the time of automatic termination due to battery exhaustion, thereby preventing unauthorized leakage of the communication list information of the user There is also an advantage.

Although the above has been described with reference to a preferred embodiment of the present invention, those skilled in the art to which the present invention pertains without departing from the spirit and scope of the present invention as set forth in the claims below It will be readily understood that modifications and variations are possible.
