Detailed Description

Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

Fig. 1 is a flowchart of steps of a data backup method provided in an embodiment of the present invention, where the method is applied to a first terminal, and data to be backed up is stored locally in the first terminal, as shown in fig. 1, the method may include:

step 101, receiving a backup instruction under the condition that the SIM card is arranged in the first terminal.

A Subscriber Identity Module (SIM) card is also called a smart card, and a terminal needs to be equipped with the SIM card to use the SIM card normally. In addition, the SIM card has a certain storage space, and the storage space in the SIM card can store short message information and/or contact information. In the embodiment of the present invention, the SIM card may be inserted into or removed from the first terminal, and when the SIM card is disposed in the first terminal, the first terminal may access the storage space in the SIM card, and the first terminal may obtain the data in the storage space and store the data in the local of the first terminal, or move the data in the local of the first terminal to the storage space.

The first terminal may locally store data to be backed up, where the data to be backed up may be short message information, contact information, and other user information. When the SIM card is set in the first terminal, the history data stored in the SIM card may also be stored in the local temporary storage space of the first terminal, so as to achieve the purpose of backing up the data in the SIM card.

In the embodiment of the invention, under the condition that the SIM card is arranged in the first terminal, the first terminal can receive the backup instruction through the preset quick backup inlet.

The shortcut backup entry can be specifically realized in a shortcut backup entry icon manner, that is, a user can click the shortcut backup entry icon displayed in the first terminal interface to receive a backup instruction, so that the purpose of one-key backup is achieved, and the problem that a backup operation trigger path is too deep in the prior art can be solved.

And 102, under the condition that the residual capacity value of the SIM card is smaller than the capacity value of the data to be backed up, selecting target backup data with the same data capacity as the residual capacity value from the data to be backed up according to the backup instruction, and storing the target backup data into the SIM card.

In the embodiment of the invention, after the SIM card is arranged in the first terminal, the first terminal can acquire the capacity information of the storage space of the SIM card and obtain the remaining capacity value of the SIM card, and under the condition that the remaining capacity value of the SIM card is smaller than the capacity value of the data to be backed up, the target backup data with the same data volume as the remaining capacity value can be selected from the data to be backed up according to the backup instruction, and the target backup data is stored in the SIM card.

Specifically, each data file in the data to be backed up may be sorted according to a preset sequence to form a data sequence, and target backup data having a data volume equal to the remaining capacity value is selected from the data to be backed up.

In addition, after the target backup data is stored in the SIM card, the first terminal may locally delete the target backup data to save a local storage space of the first terminal, and in addition, the first terminal may also locally retain the target backup data, which is not limited in the embodiment of the present invention.

For example, if the data to be backed up includes 10 pieces of short message information, the 10 pieces of short message information may be sorted according to the time stamps of the 10 pieces of short message information, so as to obtain a short message sequence, and a plurality of pieces of short message information having a total capacity that is the same as the remaining capacity value of the SIM card are selected from the earliest or latest end of the short message sequence, and the selected plurality of pieces of short message information are stored in the SIM card.

It should be noted that, when the remaining capacity value of the SIM card is greater than or equal to the capacity value of the data to be backed up, the data to be backed up may be directly stored in the SIM card according to the backup instruction.

Step 103, after the SIM card is moved out of the first terminal, if the SIM card is set in the first terminal again, all data in the SIM card is cleared.

In the embodiment of the present invention, after the target backup data is stored in the SIM card, the storage space of the SIM card is not left, at this time, the SIM card may be moved out of the first terminal, and the SIM card is set in the second terminal to which the data is to be restored to perform the data restoration operation, after the data restoration operation is completed, the SIM card may be set in the first terminal again, and when the SIM card is set in the first terminal again, all the data in the SIM card may be cleared, so that a sufficient space is reserved in the SIM card to store other backup data except the target backup data in the data to be backed up.

In step 101, when the SIM card is first set in the first terminal, since the history data stored in the SIM card is already stored in the local temporary storage space of the first terminal, the history data stored in the local temporary storage space of the first terminal can be recovered to the SIM card when the history data in the SIM card needs to be recovered subsequently, thereby avoiding the loss of the history data in the SIM card.

And step 104, after all the data in the SIM card are cleared, storing other backup data except the target backup data in the data to be backed up to the SIM card.

In the embodiment of the present invention, when the SIM card is set in the first terminal again, it may be considered that the data to be backed up for the first time is backed up to the second terminal, and at this time, other backup data except the target backup data in the data to be backed up may be stored in the SIM card.

Specifically, the storing of the other backup data to the SIM card may include acquiring a capacity value of the other backup data, and if the capacity value of the other backup data is less than or equal to the total capacity value of the SIM card, directly storing the other backup data to the SIM card. If the capacity value of the other backup data is larger than the total capacity value of the SIM card, data with the same capacity value as the total capacity value of the SIM card can be selected from the other backup data, and stored in the SIM card, and when the SIM card is removed and set again, the remaining data in the other backup data is stored in the SIM card until the data to be backed up of the first terminal is all restored to the second terminal.

To sum up, the data backup method provided by the embodiment of the present invention includes receiving a backup instruction when the SIM card is set in the first terminal; under the condition that the residual capacity value of the SIM card is smaller than the capacity value of the data to be backed up, selecting target backup data with the same data quantity and residual capacity value from the data to be backed up according to a backup instruction, and storing the target backup data to the SIM card; after the SIM card is moved out of the first terminal, if the SIM card is set in the first terminal again, all data in the SIM card are removed; and after all the data in the SIM card are cleared, storing other backup data except the target backup data in the data to be backed up to the SIM card. The invention can utilize the storage space of the SIM card to store and backup the local data to be backed up of the first terminal in batches; and through the storage space of the SIM card, the backup data stored in the storage space is restored to the local of the second terminal in batches, and the whole backup and restoration operation only requires a user to insert and pull the card without depending on a network environment, so that the complexity of the operation is reduced, and the success rate and the efficiency of the data backup and restoration are improved.

Fig. 2 is a flowchart of specific steps of a data backup method provided in an embodiment of the present invention, where the method is applied to a first terminal, and data to be backed up is locally stored in the first terminal, as shown in fig. 2, the method may include:

step 201, receiving a backup instruction under the condition that the SIM card is arranged in the first terminal.

This step may specifically refer to step 101, which is not described herein again.

Step 202, determining the repeated data which is the same as the historical data from the data to be backed up.

In the embodiment of the invention, when the SIM card is arranged in the first terminal, the history data stored in the SIM card can be stored in the local temporary storage space of the first terminal, so as to achieve the purpose of backing up the data in the SIM card.

After the history data stored in the SIM is stored in the local temporary storage space of the first terminal, the data with backup locally stored in the first terminal may be matched with the history data, the duplicate data in the data to be backed up, which is the same as the history data, may be determined, and a duplicate tag may be marked on the duplicate data.

Step 203, deleting the repeated data in the data to be backed up.

In this step, if there is duplicate data identical to the data to be backed up in the history data of the SIM, the duplicate data may be deleted from the data to be backed up, so as to avoid duplicating the duplicate data to the SIM card.

For example, for the contact information, if the history data of the SIM card stores the contact information of "zhang san" and the address book application of the first terminal also stores the contact information of "zhang san", if the data in the address book application of the first terminal is taken as the data to be backed up and backed up to the SIM card, the contact information of "zhang san" may be removed from the data to be backed up, so as to avoid duplicate copying of the contact information of "zhang san".

And 204, under the condition that the residual capacity value of the SIM card is smaller than the capacity value of the data to be backed up, selecting target backup data with the same data capacity as the residual capacity value from the data to be backed up according to the backup instruction, and storing the target backup data into the SIM card.

This step may specifically refer to step 102, which is not described herein again.

Optionally, in an implementation manner of the embodiment of the present invention, the data to be backed up includes a plurality of pieces of short message information, and step 204 may specifically include:

and a substep 2041 of sequencing the short message information according to the timestamp corresponding to the short message information to obtain a short message sequence.

In the embodiment of the invention, if the short message information is the received short message information, the timestamp corresponding to the short message information can be the receiving time when the short message information is received; if the short message information is the sent short message information, the timestamp corresponding to the short message information may be the sending time when the short message information is sent.

According to the timestamp corresponding to the short message information, the short message information can be sequenced from morning to evening or from evening to morning according to the time, so as to obtain a corresponding short message sequence.

Substep 2042, starting from one end of the short message sequence, selecting a plurality of continuous first short message messages with the same data volume as the residual capacity value, and storing the plurality of continuous first short message messages to the SIM card.

In the embodiment of the present invention, a plurality of consecutive pieces of first short message information may be selected from an earliest end or a latest end of the short message sequence, a data amount of the plurality of consecutive pieces of first short message information is the same as a remaining capacity value of the SIM card, and the plurality of consecutive pieces of first short message information are stored in the SIM card. After a plurality of continuous first short message information are stored in the SIM card, the storage space in the SIM card is full, at the moment, the first terminal can record the short message information of the last storage operation execution, so that the short message information after the short message information of the last storage operation execution is selected for backup in the short message sequence when the SIM card is arranged at the first terminal again next time.

In addition, after storing the consecutive pieces of first short message information to the SIM card, the first terminal may further generate a card pulling notification, such as: when the current SIM card is full of memory, please pull out the SIM card and set the SIM card in the mobile phone to be restored for data restoration. And informing the user that the storage space of the current SIM card is full, pulling out the SIM card from the first terminal, and setting the SIM card in the second terminal for data recovery.

Optionally, in an implementation manner of the embodiment of the present invention, the data to be backed up includes information of a plurality of contacts, and step 204 may specifically include:

substep 2043, determining the number of fields of the contact information.

In practical application, since in the storage space of the SIM card, there are usually specified upper limits of storage fields and limitations of storage field types for a piece of contact information, there is often no such requirement in the mobile terminal, which makes it impossible to completely backup the contact information in the mobile terminal, which includes more fields or has SIM card unrecognizable fields, into the SIM card, in the embodiment of the invention, the contact information with the number of fields exceeding the preset threshold value can be divided into a plurality of segment information storages, each segment information is regarded as one piece of contact information, and adds an identification corresponding to the contact only to a plurality of segment information under the same contact name, therefore, when the SIM card recovers the contact information at the second terminal, the second terminal can find a plurality of pieces of segment information under one contact name according to the identification and combine the plurality of pieces of segment information into one piece of contact information.

In this step, the contact information of the SIM card supports only saving fields of several types, i.e. name, phone Number, Additional Number (ANR), e-mail, and group, and each field has an upper limit of the Number of words, and the Number of fields of the contact information is determined, which may be the total Number of words for each type of field in the contact information.

And a substep 2044 of adding a corresponding contact identifier to the contact information when the number of fields of the contact information is less than or equal to a preset threshold value.

In this step, for the contact information in which the number of a field in the first terminal is less than or equal to the preset threshold and no unrecognizable field of the SIM card exists, a corresponding contact identifier may be directly added to the contact information, so that when the SIM card is set in the second terminal, the corresponding contact identifier is directly added according to the contact information, the contact information is imported into the address book application, and a corresponding contact is created. The contact person information added with the corresponding contact person identification can be the name of the contact person.

Substep 2045, when the number of fields of the contact information is greater than the preset threshold, splitting the contact information into a plurality of pieces of contact sub information, and adding a contact identifier corresponding to the contact information to each piece of contact sub information, wherein the number of fields of the contact sub information is less than or equal to the preset threshold.

In this step, for the contact information in which one field number is greater than the preset threshold and the SIM card unrecognizable field exists in the first terminal, the contact information may be split into a plurality of pieces of contact sub-information whose field number is less than or equal to the preset threshold, and a contact identifier corresponding to the contact information is added to each piece of contact sub-information.

Specifically, under the condition that the contact information of the SIM card only supports the storage of fields of types such as name, phone number, Additional Number (ANR), email, packet, and the like, for contact information whose field number is greater than a preset threshold and where there is a field that the SIM card cannot identify, different contact sub-information of the same contact may be classified into the same group by using a contact identifier, and further, different contact sub-information in the same group may be marked and distinguished by using an additional number field, so that one piece of contact information may be divided into multiple pieces of contact sub-information for storage, and when the contact information is restored, the contact sub-information may be queried and spliced by using the above rules.

Wherein, for the distribution of the contact person identification, the method comprises the following steps: judging whether a group named by a number exists in the current contact information, if not, splitting the contact information, wherein the contact identification used in the splitting of the contact information starts from the number 1, and if the group named by the number n exists, the contact identification starts from the position behind the existing number group name (namely n + 1).

Assignment of different contact sub-information for the same group: the contact sub-information corresponding to the name field may record current additional information (e.g., birthday, remarks, ring name, company name, home address, nickname, etc.); the contact person sub-information corresponding to the telephone number field can be used for recording the birthday date; the contact sub-information corresponding to the ANR field is used to distinguish the above-mentioned additional information. The ANR field is composed of two parts, the first part is four digits and is used for distinguishing current information, the second part is a real ANR number, and the specific allocation includes: the first digit in the first four digits represents whether the current contact has an additional number (0 represents no, 1 represents present), the second digit represents the number of the additional information (e.g. 0 represents the additional number, 1 represents birthday, 2 represents remark, 3 represents ring, 4 represents company name, 5 represents address, 6 represents nickname, etc., and at most 9 items are supported), the third digit represents how many pieces of the current additional information are, and the fourth digit represents the fourth piece of the current additional information.

For example, for one contact information: "name: and (5) opening the leaf. Telephone number: 123456. additional number: 5678. birthday: 1999.09.09. ringing: the song name. Company name: a company name. The house address: street address specific information. Nickname: a nickname. Remarking: xxxxxxxxxx ".

After the contact information is split into a plurality of contact sub-information, the following contents can be obtained:

contact person sub-information 1: name: zhang three telephone numbers: 123456 additional number: 00005678 contact identification: 1

Contact person sub-information 2: name: birthday telephone number: 1999.09.09 additional numbers: 1111 contact identification: 1

Contact person sub-information 3: name: xxxxxxxxxx telephone number: additional number: 1211 contact identification: 1

Contact person sub-information 4: name: song name phone number: additional number: 1311 contact identification: 1

Contact person sub-information 5: name: company name telephone number: additional number: 1411 contact identification: 1

Contact person sub-information 6: name: street address specific letter telephone number: additional number: 1521 contact identification: 1

Contact person sub-information 7: name: telephone number of message: additional number: 1522 contact identification: 1

Contact person sub-information 8: name: nickname telephone number: additional number: 1611 contact identification: 1.

as can be seen from the above, when the number of words of the additional information exceeds the maximum number of words (7) storable in the name field, the divided information is stored, and how many pieces of information are currently divided and currently belong to the second segment are retained in the additional number information. Thus, when the SIM card is set to the second terminal, the second terminal can perform matching population by reading these fields.

Substep 2046, classify the contact person identification to get multiple categories.

In this step, the contact information corresponding to the contact identifier can be classified according to the frequency of use of the contact information corresponding to the contact identifier by the user and the keyword information acquired when the user makes a call or receives and sends a short message, so as to obtain a plurality of categories.

For example, for a category in which contact information that is used more frequently is labeled as a parent, the category may be processed preferentially when backup or recovery of contact information is performed. For a category of contacts marked as strangers for which infrequent use contact information is made, the category may be processed with hysteresis as backup of contact information is performed.

Substep 2047, according to preset rules, adding weight values to each of the categories.

In the embodiment of the invention, the corresponding weight value can be set for the category according to the use frequency of the contact person information in the category, and the higher the use frequency of the contact person information in the category is, the larger the weight value of the category is; the lower the frequency of use of the contact information in the category, the smaller the weight value of the category.

Substep 2048, selecting a plurality of pieces of first contact information with the same data volume as the residual capacity value from the category with the largest weight value according to the backup instruction, and storing the first contact information in the SIM card.

In the embodiment of the present invention, when performing backup operation, backup of contact information in corresponding categories may be performed in an order from a large weight value to a small weight value, and after the backup of contact information in a category with a large weight value is completed, backup processing may be further performed on contact information in a category with a small weight value, where some first contact information including a plurality of first contact sub-information may exist in all first contact information in the category, that is, a set of first contact sub-information having the same contact identifier may be used as one first contact information.

Substep 2049, among the classes not yet backed up, determines the target class with the largest weight value.

After the storage space in the SIM card is full, if there are other categories for which contact information is not backed up, the target category with the largest weight value may be determined among the categories for which backup is not completed, and a notification is generated to prompt the user which categories are currently backed up, which categories are not backed up, and the category with the highest priority among the categories for which backup is not completed (for example, parent category backup is completed, friend category backup is completed, remaining colleague categories and stranger categories are not completed, and backup is requested to start from the colleague categories for the next backup).

Step 205, after the SIM card is removed from the first terminal, if the SIM card is set in the first terminal again, all data in the SIM card is cleared.

This step may specifically refer to step 103, which is not described herein again.

Step 206, after all data in the SIM card are cleared, storing other backup data in the data to be backed up, except the target backup data, to the SIM card.

This step may specifically refer to step 104, which is not described herein again.

Optionally, in an implementation manner of the embodiment of the present invention, the data to be backed up includes multiple pieces of short message information, and step 206 may specifically include:

substep 2061, removing the continuous first short message messages from the short message sequence.

In this step, after all the short message information in the SIM card is restored to the second terminal and all the data in the SIM card is cleared, consecutive pieces of first short message information restored to the second terminal may be removed from the short message sequence, where the removing operation may be to remove consecutive pieces of first short message information in the short message sequence and delete the data content of consecutive pieces of first short message information; or only moving out continuous first short message information in the short message sequence, and not deleting the data content of the continuous first short message information.

A substep 2062, starting from one end of the short message sequence, selecting a plurality of continuous second short message messages with the data volume same as the total capacity value of the SIM card, and storing the plurality of continuous second short message messages to the SIM card.

In the embodiment of the invention, because continuous pieces of first short message information which are backed up to the second terminal are removed from the short message sequence, and the storage space of the SIM card is empty, in the step, continuous pieces of second short message information with the data volume being the same as the total capacity value of the SIM card can be selected from one end of the short message sequence in the short message sequence, and the continuous pieces of second short message information are stored in the SIM card, so that the aim of further linking the next backup operation from the short message information of which the last backup operation is finished is fulfilled until all the short message information is backed up.

Optionally, in an implementation manner of the embodiment of the present invention, the data to be backed up includes information of a plurality of contacts, and step 206 may specifically include:

substep 2063, starting from the target category, selecting a plurality of pieces of second contact information with the data volume being the same as the total capacity value of the SIM card, and storing the second contact information in the SIM card.

In the embodiment of the present invention, after the storage space in the SIM card is full, if there are contact information in other categories that are not backed up, the target category with the largest weight value may be determined in the category that is not backed up according to the operation of step 2049, in this step, when the SIM card is moved out of the first terminal and is set in the first terminal again, the first terminal may select, starting from the target category, a plurality of pieces of second contact information having the same data volume as the total capacity value of the SIM card, and store the second contact information in the SIM card until after multiple rounds of SIM card removal and insertion operations, all pieces of classified contact information are backed up.
