Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
A method for uniformly managing local data and user identification card data in communication terminal, such as mobile phone, is provided, which corresponds the data in user identification card to a storage area of memory, avoiding reading from user identification card every time needing to inquire the corresponding data in card. The present invention is based on the improvement of this unified management method.
Referring to fig. 1, a flowchart of a method for implementing data synchronization between a memory and a subscriber identity module according to an embodiment of the present invention is shown. The invention provides a method for realizing data synchronization of a memory and a user identification card, which comprises the following steps:
step 101: and establishing a data table in the memory, establishing a mapping relation between a preset index value and a storage position in the user identification card, and storing the data of the user identification card in the storage position.
In the invention, the user identification card can comprise a sim card, a ruim card and a usim card, and the data in the card can be number information and/or short message information.
Taking the subscriber identification card as a sim card and the data in the card as short message information as an example, firstly, a data table iccsss table is established in an information database provider stored in a mobile phone, wherein the provider is used for storing all short message information of the mobile phone, including local short messages and short messages in the sim card.
In this embodiment, the preset index value is used to specify the sequence of the physical storage locations in the sim card, for example, if 60 short messages can be stored in the sim card at most, the index value is 1-60. And establishing a mapping relation between the preset index value and the storage position, wherein the relation is a one-to-one correspondence relation, for example, the preset index value is 1, and the first short message corresponds to the preset index value. It should be noted that, when the short message is deleted from a certain storage location, the preset index value corresponding to the storage location still exists.
Step 102: and storing the preset index value and the user identification card data in the data table.
This step is a process of initializing the data table. Illustratively, the android system sends a BOOT _ COMPLETED broadcast when the mobile phone is powered on, the mobile phone starts Smsservice after receiving the broadcast, a getAllMessageFromIcc standard card reading interface function is called in an interface type SmsManager of a frame layer short message, so as to obtain a preset index value and short message information in a sim card, and information content, sending or receiving time, information type and the like are extracted from the short message information. And then, calling a sqlite insert function to insert the obtained content into the iccsss table to complete the initialization of the data table.
In order to further increase the stability of the scheme, related protection measures are added, for example, in a low-memory mobile phone, due to the fact that a lot of services are provided for related operations when the mobile phone is started, the applied services are often closed in the background according to the kernel mechanism of android, and the services are easily closed when short messages in a card are not read out due to long card reading time when a data table is initialized. For the situation, a dormant lock is added into the service for reading the data in the user identification card, and the android kernel finds that the service has the dormant lock, so that the priority of the service is improved, and the service is prevented from being closed by the kernel.
Step 103: acquiring a preset index value of changed data in the user identification card, and updating corresponding data in the user identification card into the data table according to the preset index value; or acquiring a preset index value of the changed data in the data table, and updating the corresponding data in the data table to the user identification card according to the index value.
In one embodiment, the changed data in the subscriber identity card comprises added data. In another embodiment, the changed data in the data table includes modified or deleted data. Both cases will be described in detail by the following embodiments.
The first embodiment is as follows:
in the present embodiment, the steps 201-202 are the same as the steps 101-102, and are not described herein again.
Step 203: when the data in the user identification card changes, a preset index value corresponding to the storage position of the data is obtained, and the corresponding data in the user identification card is updated into the data table according to the preset index value.
Fig. 3 is a data flow diagram for implementing data synchronization between the memory and the subscriber identity module according to an embodiment of the present invention. In this embodiment, the changed data includes added data, for example, the short message memory is preset as a sim card, and when a new short message is received, the modem directly stores the short message in the sim card. At the moment, in the framework layer, the SimRecords is called to read the information of all directories in the sim card, including the preset index value, and the service is informed in a non-standard broadcasting way, the service knows that the sim card has received the short message at the moment, the service acquires the index value in a broadcasting way, and reads the short message information corresponding to the index in the sim card according to the index value, including the information content, the sending or receiving time, the information type and other contents. And synchronously storing the acquired short message information and the index value into an iccsss table, and ensuring the synchronization of data in the data table and data in the sim card.
Preferably, when the sim card is full of short messages, the Modem automatically sets the priority memory as the mobile phone, and the terminal processes the short messages according to the normal short message reporting flow of the mobile phone when the terminal receives the short messages, so as to avoid the problem that the Modem refuses to receive the short messages due to the full short messages in the sim card.
The condition that the changed data in the subscriber identity module card comprises the added data can also be that the local short message of the mobile phone is copied to the sim card. At the moment, the copied short message information is obtained, a database provider interface is called, a card short message copying function is called in the provider, and at the moment, if a native interface is called, only a copying success or failure result is returned, and the short message index value copied to the sim card cannot be obtained. The native interface is expanded in the scheme, and the corresponding interface function of the frame layer is modified, so that the index value can be returned. And if the copy is successful, inserting the returned index value and the short message information acquired by calling the card short message copy function into an iccsss table of the database. If the failure occurs, the insertion operation of the database is not executed, and the result is fed back to the user.
Preferably, the obtaining of the preset index value of the changed data in the subscriber identity card comprises: judging whether the data in the user identification card reaches a preset storage upper limit, if so, ending the process; otherwise, the flow is continued. For example, when the user performs the copying operation on the mobile phone interface, the number of the short messages in the sim card can be known from the data table, so that whether the short messages in the sim card are full can be judged, if so, the short messages are directly fed back to the user, and the short messages cannot be copied to the sim card.
The embodiment of the invention ensures that when the user identification card has newly added data, only the preset index value of the changed data needs to be acquired, the corresponding data content is found according to the mapping relation between the preset index value and the storage position in the user identification card and the data stored in the user identification card, and the corresponding data content is inserted into the data table to update the data in the data table. For other data without change, reading is not needed, and the data synchronization speed is improved.
Example two:
in the present embodiment, the steps 301-302 are the same as the steps 101-102, and are not described herein again.
Step 303: and when the data in the data table changes, acquiring a preset index value of the changed data in the data table, and updating the corresponding data in the data table to the user identification card according to the index value.
The changed data in this embodiment includes modified or deleted data. For example, when a user needs to delete the short messages in the sim card, all the short messages in the sim card are displayed on a mobile phone interface, and the short messages are selected to be deleted. In the scheme, data is read from the memory, and only the short messages in the memory are deleted at the moment, so that the short messages corresponding to the sim card also need to be deleted. The method comprises the steps of obtaining an index value which is originally stored in a data table and corresponds to a short message selected by a user, calling a standard short message deleting function deleteMessageFromIcc on a card when the user confirms deletion, transmitting the index value into the function, and enabling the Modem to carry out short message deleting operation in the sim card through a frame layer.
