Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Fig. 1 is a schematic structural diagram of a terminal in one embodiment. As shown in fig. 1, the terminal includes a processor, a nonvolatile storage medium, an internal memory, a data transmission interface, a display screen, and an input device, which are connected through a system bus. Wherein the non-volatile storage medium of the terminal stores an operating system and computer readable instructions that are executed by the processor to implement a multi-operator implementation method. The processor is used for providing calculation and control capability and supporting the operation of the whole terminal. The data transmission interface is used for communicating with other mobile storage devices. The display screen of the terminal can be a liquid crystal display screen or an electronic ink display screen, and the input device can be a touch layer covered on the display screen or a key arranged on a shell of the terminal. It will be understood by those skilled in the art that the structure shown in fig. 1 is a block diagram of only a part of the structure relevant to the present application, and does not constitute a limitation of the terminal to which the present application is applied, and in particular, the terminal may include more or less components than those shown in the drawings, or combine some components, or have a different arrangement of components.
In one embodiment, as shown in fig. 2, a multi-operator implementation method is provided, which is exemplified by being applied to a terminal shown in fig. 1, and includes:
A Subscriber Identity Module (SIM) card, also called a smart card, for identifying the identity of a Subscriber using a Global System for Mobile Communication (GSM) network; the operator is a provider providing network services, the operator identifier is an identifier for uniquely distinguishing the operator, and the operator identifier is a self-defined identifier for establishing a mapping relationship in this embodiment.
Specifically, the terminal reads information of the SIM card, such as a state, a serial number, a provider code, a provider name, a country, a contact person, and the like, after being powered on, and if one or more of the above information of the SIM card is successfully read, searches for an operator identifier corresponding to the inserted subscriber identity module card in a configuration information partition of a data storage flash memory (i.e., nand flash).
And step 204, if the obtained operator identification is different from the currently running operator identification, restarting and entering a boot stage.
Boot (BootLoader) is a boot program that is run in an embedded system before the kernel of an operating system runs and is used for initializing hardware equipment and establishing a memory space map. The operator identifier currently running is the operator identifier corresponding to the operator currently used by the system.
In step 206, the operator image file corresponding to the acquired operator identity is loaded in the boot phase.
The mirror image file is similar to the rar and ZIP compressed package, and a series of specific files are made into a single file according to a certain format, so that the file is convenient for a user to download and use; the operator image file is an image file formed by compiling general configuration information divided by an operator according to a preset rule (for example, divided into a chinese operator, an american operator, and the like according to an area) into an operating system, where the general configuration information refers to the same configuration information used by different operators, such as a locking function of a modem for supporting an SIM card. Specifically, as shown in fig. 3, the nand flash is divided into an operator mirror Image storage Partition (Image data Partition), an operator configuration information Partition (configuration data Partition), and another data storage Partition (Other data Partition) in advance. A plurality of operator mirror image files are stored in the operator mirror image storage partition; the operator configuration information Partition is stored with a plurality of operator configuration data, a Mapping table (Mapping of Image ID and Image data) of operator identification and operator Image file, and a Mapping table (Mapping of Image ID and configuration data Partition) of operator identification and operator configuration data. The image file storage partition of the nand flash currently stores at most four operator image files, and because the nand flash currently supports 128M at most, each operator image file can be allocated with 25M. At the boot loader stage, as shown in fig. 4, an operator image file corresponding to the acquired operator identifier is loaded in a pre-partitioned image file storage partition of the nand flash.
And step 208, starting the operator mirror image file corresponding to the acquired operator identifier, entering an operating system, and loading the operator configuration data corresponding to the acquired operator identifier.
In this embodiment, the operator configuration data is different configuration data of different operators, that is, dedicated configuration data of the operators.
In order to load the complete configuration information of the operator corresponding to the user identification card inserted into the current system, as shown in fig. 4, in addition to loading the general configuration data (i.e., the operator image file) of the operator corresponding to the user identification card inserted into the current system, which is stored in the operator image file, the specific configuration data of the operator corresponding to the user identification card inserted into the current system also needs to be loaded, for example, the specific configuration data of the chinese mobile operator has a chinese mobile multimedia message access point which is cmwap.
In this embodiment, when it is detected that the user identification card is inserted into the current system, an operator identifier corresponding to the inserted user identification card is acquired, and if the acquired operator identifier is different from the currently running operator identifier, the system is restarted and enters a boot stage, an operator image file corresponding to the acquired operator identifier is loaded in the boot stage, the operator image file corresponding to the acquired operator identifier is started, and operator configuration data corresponding to the acquired operator identifier is loaded after the system enters the operating system. Because the operator mirror image file corresponding to the user identity identification card is loaded firstly and then the operator configuration data corresponding to the user identity identification card is loaded, each operator can realize unlimited support through a mode of adding the general configuration data and the special configuration data, and the problem of limited support of the operators is solved.
In one embodiment, as shown in fig. 5, the obtaining of the operator identifier corresponding to the inserted subscriber identity card in step 202 includes:
The identification code of the user identification card, i.e. the card number of the SIM card, is composed of 20 digits, the first six digits are operator codes, as for the mobile in china: 898600, respectively; 898602, China Union: 898601, 898609, china telecom 898603, 898606.
The operator configuration information storage partition is a storage area which is pre-divided in the nand flash and is used for storing a mapping table and operator special configuration data; the mapping table of the user identification card identification codes is a mapping relation between the predefined user identification card identification codes and the operator identifications.
In step 216, if the reading fails, the plmn identity of the currently inserted subscriber identity card is obtained.
Public Land Mobile Networks (PLMN) are networks established and operated by the government or its approved operators for the purpose of providing Land Mobile services to the Public; the plmn identity is an identifier for distinguishing a plmn, for example, the plmn identity of china mobile is 46000, and the plmn identity of china unicom is 46001.
Because there may be no record of the identification code of the inserted subscriber identity card in the subscriber identity card identification code mapping table, the operator identifier corresponding to the identification code of the inserted subscriber identity card cannot be read, and at this time, the corresponding operator identifier can be obtained by obtaining the public land mobile network identification code of the inserted subscriber identity card.
In step 218, the operator id corresponding to the obtained plmn id of the subscriber identity card is read from the plmn id mapping table in the operator configuration information storage partition.
The mapping table of public land mobile network identification codes is a mapping relation between predefined public land mobile network identification codes and operator identifications.
In this embodiment, the operator identifier corresponding to the inserted identification card is obtained by using the combination of the identification code of the inserted identification card and the public land mobile network identification code, and for the operator identifier corresponding to the identification card obtained only by the identification code of the inserted identification card, the confirmation rate of confirming the operator corresponding to the inserted identification card is improved.
In one embodiment, step 206 is preceded by: verifying the safety of the operator mirror image file corresponding to the operator mirror image file identification; and if the operator identity is verified to be safe, starting the operator mirror image file corresponding to the obtained operator identity. In this embodiment, the security of the operator image file corresponding to the obtained operator identifier is ensured by adding the security verification step to the operator image file corresponding to the obtained operator identifier.
In an embodiment, as shown in fig. 6, the step of verifying the security of the operator image file corresponding to the operator image file identifier includes:
A digital signature is some data appended to a data unit or a cryptographic transformation performed on a data unit that allows the recipient of the data unit to verify the source of the data unit and the integrity of the data unit and to protect the data from being counterfeited by a person (e.g., the recipient).
And step 604, decrypting the acquired digital signature by using a pre-stored key algorithm to obtain a first message digest of the operator image file corresponding to the acquired operator identity.
The pre-stored key algorithm is an algorithm which is pre-stored in the terminal and used for encryption or decryption; a message Digest (MessageDigest), also known as a Digital Digest (Digital Digest), is a fixed-length value that uniquely corresponds to a message or text. The message digest uses a one-way Hash function to digest the plaintext to be encrypted into a string of 128-bit ciphertext, which is also called digital fingerprint (Finger Print), and has a fixed length, and different plaintext digests are the ciphertext, and the result is always different, and the digests of the same plaintext must be identical. In this embodiment, after the digital signature of the operator image file corresponding to the acquired operator identity is acquired, the acquired digital signature is decrypted by using a key algorithm (such as an RSA algorithm) pre-stored in the terminal to obtain the first message digest.
The message digest algorithm is also called hash algorithm, is a very important branch in the cryptographic algorithm, and realizes the functions of data signature, data integrity check and the like by extracting fingerprint information from all data. The Message Digest Algorithm may be a Cyclic Redundancy Check Algorithm (CRC, including CRC8, CRC16, and CRC32), a Secure Hash Algorithm (SHA, including SHA1, SHA256, SHA384, SHA512), a Message Digest Algorithm (Message Digest Algorithm, including MD2, MD4, MD5), or the like.
Specifically, a plaintext message in the operator image file corresponding to the acquired operator identifier is converted into a hash value with a fixed length through a message digest algorithm, which is the second message digest.
In this embodiment, the security of the operator image file corresponding to the acquired operator identity is verified by comparing a message digest obtained by decrypting the digital signature of the operator image file corresponding to the acquired operator identity using the pre-stored key algorithm with a message digest obtained by converting plaintext information in the operator image file corresponding to the acquired operator identity using the message digest algorithm.
In an embodiment, as shown in fig. 7, the step of loading the operator configuration data corresponding to the obtained operator identifier after entering the operating system includes:
The header is a piece of data at the beginning of the file that takes on a certain task.
In this embodiment, a plurality of operator configuration files are stored in the operator configuration information storage partition to support different operators.
The file header of each operator configuration file records the operator identification corresponding to the operator configuration file, so that the special configuration data of the operators corresponding to the user identification cards of different operators can be conveniently loaded.
In this embodiment, the corresponding operator identifier is obtained by traversing and analyzing the file header of each operator configuration file in the operator configuration partition, the operator configuration file corresponding to the inserted user identification card is found, and the configuration data in the operator configuration file is loaded.
In one embodiment, as shown in fig. 8, there is provided a multi-operator implementation apparatus, comprising:
