Description

Method for acquiring terminal independent bearer protocol information, server and smart card

technical field

The invention relates to wireless communication technology, in particular to a method for acquiring terminal independent bearer protocol information, a server and a smart card.

Background technique

With the advent of the 3G era, mobile data services have become a hot topic. There are three sources of data on the smart card used by the mobile terminal: 1. Preset in the smart card by the manufacturer when the smart card leaves the factory; Download technology (Over the Air Technology; referred to as: OTA) to download. Among them, OTA technology is an air interface through the mobile communication network, such as: Wireless Application Protocol (Wireless Application Protocol; referred to as: WAP), General Packet Radio Service (General Packet Radio Service; referred to as: GPRS), Code Division Multiple Address (Code Division Multiple Access; abbreviation: CDMA) 1X and short message, etc., the technology for remote management of smart card data and applications is currently the most commonly used data download method.

With the development of mobile data services and smart card technology, smart card services are no longer limited to the original simple menu display form, and the use of applications to expand the functions of smart cards has become the mainstream, and at the same time, the data downloaded by smart cards also has hundreds to thousands of words. Sections, now tens of thousands of bytes or even more, and with the development of smart card technology and the increase of smart card space, this number is still rising. Therefore, the existing OTA technology using the SMS channel can no longer meet the needs of smart card business development, so the OTA technology based on the Bearer Independent Protocol (abbreviated as: BIP) appeared. Among them, BIP is a connection-oriented transmission protocol proposed by ETSI TS 102 223, which enables the smart card to establish a connection-oriented data channel through the terminal and the remote server, and can be used in the Global System for Mobile Communications (Global System for Mobile Communications; referred to as: GSM) , CDMA, Universal Mobile Telecommunications System (Universal Mobile Telecommunications System; referred to as: UMTS) and other mobile communication networks.

OTA using BIP (referred to as BIP-OTA) technology is mainly a downloading technology that uses a high-speed wireless data channel to download data to a smart card through a terminal. One way of using BIP-OTA technology in the prior art is: a relationship table is pre-established on the remote server that stores the mapping relationship between the user ID, terminal model, and terminal BIP capability; the remote server obtains user information according to the request message of the user terminal, Query the relationship table to judge the BIP capability of the corresponding terminal, and then determine whether the terminal can use the BIP-OTA technology to download data according to the judgment result, so as to determine the way the user finally obtains the data.

In the prior art, the way for the remote server to establish the relationship table is: the remote server initiates a BIP PUSH command for a specific user group, so that the smart card initiates an active command to the terminal, such as an open channel (OPEN CHANNEL) command, and the remote server responds to the OPEN CHANNEL command according to the terminal. The processing results are used to judge the BIP capability of the terminal. If the terminal accesses the remote server within the valid time, it means that the terminal supports the BIP capability, and the remote server will establish a mapping relationship between the terminal and the BIP capability; otherwise, it means that the terminal does not support the BIP capability. This method requires the terminal to establish a connection with the remote server through a wireless access point (Access Point Name; APN for short). Generally, the mobile phone requires the user to click "Confirm" to establish a connection. If the user does not click for a long time, it will be valid After the time is over, the remote server will think that the terminal does not support the BIP capability, and the BIP PUSH command initiated by the remote server is mostly during the idle period of the system (usually 12:00-3:00 in the middle of the night), so this The accuracy rate of the judgment result of the terminal BIP capability by this method is not high.

Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

FIG. 1 is a flowchart of a method for acquiring terminal BIP information provided by Embodiment 1 of the present invention. As shown in Figure 1, the method of the present embodiment includes:

Step 11: The smart card sends a terminal BIP capability verification request to the server, and the terminal BIP capability verification request includes a user identifier.

The smart card in this embodiment refers to a service card embedded in a mobile terminal, such as a Universal Subscriber Identity Module (USIM) card or a Subscriber Identity Module (SIM) card. In this embodiment, the smart card is embedded in the terminal and used by the user. Wherein, the user identifier is used to uniquely identify a user; when the terminal is a mobile phone, the user identifier is usually the user's mobile phone number.

Specifically, the smart card sends a terminal BIP capability verification request to the terminal where the smart card is located through an active command, such as "SEND DATA", to request the terminal to forward the terminal BIP capability verification request to the server in the form of a short message. Among them, "SEND DATA" may be an instruction including a terminal BIP capability verification request, and at the same time, the instruction is also used to instruct the terminal to encapsulate the terminal BIP capability verification request in a short message and send it to the server.

Wherein, the active command that the smart card sends the terminal BIP capability verification request to the terminal, and the specific information of the sent terminal BIP capability verification request can be defined by itself, which is not limited in this embodiment.

Step 12: The server sends a BIP PUSH command to the smart card according to the terminal BIP capability verification request, and the BIP PUSH command includes the server's Internet Protocol (Internet Protocol; referred to as: IP) address and port number.

Specifically, after receiving the terminal BIP capability verification request forwarded by the terminal, the server sends a BIP PUSH command to the smart card through the terminal. The BIP PUSH command is mainly used to make the smart card initiate an active command such as "OPEN CHANNEL" to open the data channel for interaction between the terminal and the smart card, and the BIP PUSH command includes information such as the server's IP address and port number. Usually, the user datagram protocol (User Datagram Protocol; UDP for short) is used for information exchange between the server and the terminal. Therefore, the port number of the server in this embodiment mainly refers to the UDP port number.

Step 13, the smart card sends an OPEN CHANNEL command to the terminal according to the BIP PUSH command, so that the terminal establishes a connection with the server according to the IP address and port number of the server.

Specifically, the smart card sends an OPEN CHANNEL command to the terminal where it is located, so that the terminal establishes a connection with the server through the BIP channel. Wherein, if the terminal has the BIP capability, it can successfully establish a connection with the server; otherwise, it cannot establish a connection with the server.

In this embodiment, the operation of obtaining terminal BIP information is initiated by the smart card, that is, the user side. Therefore, during the connection process, even if the user needs to click "confirm" to start establishing the connection, the user can click in time, thereby It solves the problem in the prior art that the user cannot respond in time due to the incompatibility between the server's initiation time and the user's time.

Step 14, the server judges whether the terminal has BIP capability according to the access result of the terminal.

Specifically, if the server determines that the connection between the terminal and the terminal is successfully established, it indicates that the terminal has BIP capability; if the server determines that the connection between the terminal and the terminal fails to establish, it indicates that the terminal does not have BIP capability. That is, through this embodiment, the server can acquire information about whether the terminal has the BIP capability.

In the terminal BIP information acquisition method of this embodiment, the smart card actively sends a terminal BIP capability verification request to the server, the server sends a BIP PUSH command according to the smart card request, and then the smart card sends an OPEN CHANNEL command to the terminal according to the BIP PUSH command, so that the terminal and the established The server establishes the connection, and the server finally obtains information about whether the terminal has BIP capability according to the connection result. Compared with the prior art, the smart card of this embodiment changes from passive to active, and actively sends a request to the server, so that the server can send a BIP PUSH command according to the request, and can respond to the server's command in time, which solves the problem of passive reception of the smart card in the prior art. The problem that the server cannot respond to the BIP PUSH command in time improves the accuracy of the terminal BIP information obtained by the server.

FIG. 2 is a flowchart of a method for acquiring terminal BIP information provided by Embodiment 2 of the present invention. This embodiment is implemented based on Embodiment 1, and its similarities will not be repeated. As shown in Figure 2, the method of this embodiment includes:

Step 21, the smart card judges whether the terminal identification code set in the smart card and the terminal's International Mobile Equipment Identity (International Mobile Equipment Identity; abbreviated as: IMEI) code are the same; if yes, that is, when the judgment result is the same, execute step 26; Otherwise, go to step 22.

Step 22: The smart card sends a terminal BIP capability verification request to the server, and updates the terminal identification code with the IMEI code, and the terminal BIP capability verification request includes the user identification.

In this embodiment, a terminal identification code is stored on the smart card, and the terminal identification code can adopt the same encoding rule as the IMEI code of the terminal, so as to facilitate subsequent comparison with the IMEI code; wherein, the terminal identification code is initialized to a default value , such as all 0s (0x0000000000000000) or all 1s (0x111111111111111), and allow modification. The terminal identification code in this embodiment is used to determine whether the smart card is always carried by the same terminal, that is, to determine whether the terminal has changed.

Specifically, the smart card acquires the IMEI code of the terminal by actively sending an acquisition instruction to the terminal; then, the smart card compares the IMEI code of the terminal with the terminal identification code. If the comparison results are different, the smart card initiates a terminal BIP capability verification request to the server, and updates the terminal identification code with the terminal's IMEI code, that is, replaces the terminal identification code with the current terminal's IMEI code. If the comparison results are the same, the smart card ends the operation.

Wherein, this embodiment can be executed every time the user turns on the computer. When the smart card is used for the first time, the terminal identification code is the initial value, so the IMEI code of the terminal must be different from the terminal identification code. When the user turns on the device again, and because the user has changed the terminal, the IMEI code of the terminal compared with the smart card will be different from the terminal identification code. Since there is a one-to-one correspondence between the smart card and the terminal, whether it is in the initial use or when the user replaces the terminal, the smart card initiates a terminal BIP capability verification request to the server, so that the server can know the BIP capability of the user's current terminal in time, so as to Obtain the BIP information of each terminal more comprehensively; at the same time, the smart card replaces the terminal identification code with the IMEI code of the current terminal. If the user turns on the device again, the smart card will compare the IMEI code of the terminal and the terminal identification code to be the same, indicating that the user has not changed terminal, and the smart card has sent a terminal BIP capability verification request to the server, and the server has obtained the terminal's BIP information, so the smart card no longer performs the operation of sending the terminal BIP capability verification request to the server. In this embodiment, the smart card can actively initiate a terminal BIP capability verification request to the server when the user changes the terminal, but does not send the terminal BIP capability verification request when the user does not change the terminal, so that the server can keep abreast of the terminal In addition to BIP capabilities, various resources can also be saved.

Step 23: The server sends a BIP PUSH command to the smart card according to the terminal BIP capability verification request, and the BIP PUSH command includes the server's IP address and port number.

Step 24, the smart card sends an OPEN CHANNEL command to the terminal according to the BIP PUSH command, so that the terminal establishes a connection with the server according to the IP address and port number of the server.

Step 25, the server judges whether the terminal has BIP capability according to the access result of the terminal.

Step 26, end the operation.

In the terminal BIP information acquisition method of this embodiment, the smart card judges whether the user has changed the terminal by comparing the terminal identification code with the terminal's IMEI code, so as to conditionally initiate a request to the server, so that the server can obtain the accuracy and accuracy of the terminal BIP information. Timeliness has been greatly improved.

Based on the foregoing embodiments, the server establishes a terminal BIP capability mapping relationship table according to the judgment result, and defaults that the terminal does not support the BIP capability. When the server determines that the terminal has the BIP capability, it stores the information about the user identifier and the terminal having the BIP capability in a mapping relationship table, so as to establish a mapping relationship between the user identifier and the terminal having the BIP capability. Wherein, when the user replaces the terminal, the server stores the acquired information that the terminal has BIP capability in the mapping relationship table, which is equivalent to updating and maintaining the mapping relationship table, and can improve the terminal BIP capability information stored in the mapping relationship table. comprehensiveness.

Based on the mapping relationship table established by the server, when the server interacts with the smart card remotely, for example: the user sends a download request to the server through the terminal, the server will query the mapping relationship table according to the user ID in the download request to obtain whether the terminal corresponding to the user ID is With BIP capability.

When it is judged that the terminal corresponding to the user ID has BIP capability, the server sends the BIP PUSH command to the smart card through the SMS channel; the smart card sends the OPENCHANNEL command to the terminal according to the BIP PUSH command, so that the terminal can establish a connection with the server; The command determines whether the terminal opens the BIP channel, that is, determines whether the connection between the terminal and the terminal is successfully established; if the BIP channel is opened, the server transmits data to the terminal; Determine whether the BIP channel is open again. When the number of resent BIP PUSH commands exceeds the preset threshold, a notification message is sent to the terminal through the SMS channel to prompt the user to use other methods (such as SMS) to download data.

When the server determines that the terminal corresponding to the user identifier does not have the BIP capability, it notifies the user to download data in other ways through the SMS channel. In addition, the server can also determine whether to send data to the terminal through a short message according to the amount of data downloaded by the user request. For example: when the amount of data requested to be downloaded is small (take less than the preset data amount threshold as an example), the server sends data to the terminal in the form of SMS through the SMS channel; Set the data volume threshold), the server sends a notification message to the terminal to prompt the user to use other methods to download data.

Based on the above, the terminal BIP information acquisition method provided by each embodiment of the present invention has the following beneficial effects: 1. The smart card "actively" initiates a terminal BIP capability verification request to the server, and performs a BIP channel opening operation when starting up, which will greatly improve The user "discovers" and "confirms" the success rate of the Internet connection, thereby avoiding the problem in the prior art that the server sends BIP PUSH commands in the middle of the night without receiving a response from the user, and improves the accuracy of the server's acquisition of terminal BIP information. 2. The IMEI code of the terminal is verified by the smart card when it is turned on, which can accurately determine the replacement of the user terminal, facilitate the server to maintain and update the stored BIP information of the terminal in time, and improve the user's ability to download data through BIP-OTA technology At the same time, it will greatly improve the reliability of other services based on terminal BIP information. 3. Use the smart card to verify the IMEI code of the terminal. When the IMEI code does not change, it will not send a terminal BIP capability verification request to the server, which can effectively reduce the operation of sending uplink data messages when the user starts up, and reduce the impact on the wireless network. resource occupation; in addition, it can also reduce the probability that the terminal system will crash due to automatic sending of uplink text messages when the terminal is turned on. 4. The verification operation of the smart card on the terminal IMEI code does not need to consider the format of the IMEI code, which avoids problems such as the inability to identify the terminal model due to format errors. 5. The server uses the user ID as the index to establish the mapping relationship table instead of the IMEI code, which can solve the problem in the prior art that many counterfeit phones share one IMEI code and cannot establish the mapping relationship table; in addition, from the perspective of business operation , taking the user as the operation object has the advantage of being easy to manage.
