Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to an interaction method based on the enhanced bearer-independent protocol (BIP), as well as a communication card and terminal. Background Technology

[0002] BIP is an internationally standardized data exchange protocol between a communication card (or simply a card) and a remote entity. Here, the remote entity refers to an entity other than the communication card. Through BIP, the communication card can interact with the remote entity, thereby providing a secure, high-speed, and reliable data channel for services.

[0003] However, the current BIP has some drawbacks. One of these drawbacks is that the communication card can only handle one BIP connection. If the communication card has already established a BIP connection and the BIP platform initiates another connection establishment request, the request will fail and no response will be sent to the BIP platform. This makes it impossible for the BIP platform to know the connection status of the communication card. Summary of the Invention

[0004] To address the aforementioned technical problems, embodiments of the present invention provide an interaction method based on enhanced BIP, as well as a communication card, a terminal, and a computer-readable storage medium.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, in the embodiments of this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0031] It should be understood that the term "instruction" mentioned in the embodiments of this application can be a direct instruction, an indirect instruction, or an indication of a relationship. For example, A instructing B can mean that A directly instructs B, such as B being able to obtain information through A; it can also mean that A indirectly instructs B, such as A instructing C, so B can obtain information through C; or it can mean that there is a relationship between A and B.

[0032] In the description of the embodiments of this application, the term "correspondence" may indicate that there is a direct or indirect correspondence between two things, or that there is an association between two things, or that there is a relationship of instruction and being instructed, configuration and being configured, etc.

[0033] To facilitate understanding of the technical solutions of the embodiments of this application, the relevant technologies of the embodiments of this application are described below. The following relevant technologies are optional solutions and can be combined with the technical solutions of the embodiments of this application in any way, and they all fall within the protection scope of the embodiments of this application.

[0034] BIP is an internationally standardized data exchange protocol between a communication card (or simply a card) and a remote entity. Here, the remote entity refers to an entity other than the communication card. Through BIP, the communication card can interact with the remote entity, thereby providing a secure, high-speed, and reliable data channel for services. Figure 1 This diagram illustrates the protocol architecture of a server, mobile equipment (ME), and communication card, where the BIP (Block Instructions) resides on both the ME and the communication card side. It should be noted that the ME can also be referred to as a terminal, and the communication card can be simply called a card. For example, a communication card can be a Subscriber Identity Module (SIM), a Universal Integrated Circuit Card (UICC), or an embedded eUICC, etc.

[0035] ETSI TS102223 defines the following BIP proactive commands and notification events:

[0036] Active commands: Open Channel command, Send Data command, Receive Data command, Close Channel command.

[0037] Notification events: Data Available Event and Channel Status Event.

[0038] It should be noted that the above-mentioned proactive commands and notification events all belong to Application Protocol Data Unit (APDU) commands.

[0039] ESTI TS102226 defines the Remote File Management (RFM) mechanism and the Remote Application Management (RAM) mechanism. The Remote Application HTTPS mode references the Global Platform Card Specification Amendment B and implements Remote Application Management over HTTP.

[0040] Taking the RAM mechanism as an example, the BIP protocol interaction process is as follows:Figure 2 As shown, it includes the following steps:

[0041] Step 201: The BIP platform receives the request to download the application.

[0042] Here, the BIP platform is a capability platform that supports the BIP mechanism. Business platforms (i.e., business servers) or clients can send application download requests to the BIP platform.

[0043] Step 202: The BIP platform sends a data SMS message to the communication card through the terminal, carrying the connection establishment parameters.

[0044] Here, the connection establishment parameters include information such as the address and port of the BIP platform. The connection establishment parameters are used by the communication card to establish a BIP connection with the BIP platform.

[0045] Step 203: The communication card parses the data SMS and processes the connection establishment parameters.

[0046] Step 204: The communication card sends an Open Channel command to the terminal.

[0047] Step 205: After receiving the Open Channel command, the terminal establishes an HTTPS connection based on TCP / IP with the BIP platform.

[0048] It is important to note that the relationship between HTTPS connections and BIP connections is as follows: HTTPS connections are higher-level connections than BIP connections. In other words, BIP connections are lower-level connections, while HTTPS connections are higher-level connections. BIP connections and HTTPS connections correspond to different layers of the same connection.

[0049] Step 206: The BIP platform returns the processing result to the terminal.

[0050] Here, the processing result is, for example, whether the connection was successfully established.

[0051] Step 207: The terminal sends the execution result of the Open Channel command to the communication card.

[0052] Here, the execution result may be, for example, whether the connection was successfully established.

[0053] Step 208: The communication card sends the Send Data command to the terminal.

[0054] Here, the Send Data command carries an HTTPS request data command, which is used to request data to be sent from the BIP platform.

[0055] Step 209: The terminal sends an HTTPS request data command to the BIP platform.

[0056] Step 210: The BIP platform processes the request data command.

[0057] Step 211: The BIP platform returns an HTTPS response data command to the terminal.

[0058] Here, the HTTPS response data command carries the data that needs to be sent to the communication card.

[0059] Step 212: The terminal sends a Data Available Event to the communication card.

[0060] Here, the Data Available Event is used to notify the communication card that the terminal has data available to send.

[0061] Step 213: The communication card sends a Receive Data command to the terminal.

[0062] Step 214: The terminal sends data to the communication card.

[0063] Step 215: The communication card processes the data.

[0064] Step 216: The communication card sends the Send Data command to the terminal.

[0065] Step 217: The terminal sends an HTTPS request data command to the BIP platform.

[0066] Step 218: The BIP platform confirms that there is no further data and ends the interaction.

[0067] Step 219: The BIP platform returns an HTTPS response data command to the terminal, carrying a No-Content type message.

[0068] Step 220: The terminal sends a Data Available Event to the communication card.

[0069] Step 221: The communication card sends a Receive Data command to the terminal.

[0070] Step 222: The terminal sends data to the communication card.

[0071] Step 223: The communication card sends a Close Channel command to the terminal.

[0072] Here, the Close Channel command is used to trigger the closure of the BIP connection.

[0073] Step 224: The terminal sends the command result to the communication card.

[0074] It should be noted that the communication card is built into the terminal, which can also be called an ME. The BIP platform interacts with the communication card through the terminal. For ease of description, the interaction between the BIP platform and the communication card through the terminal can be directly referred to as the interaction between the BIP platform and the communication card.

[0075] The above Figure 2 In the illustrated process, the BIP platform sends a data SMS to the communication card, triggering the communication card to establish a BIP connection, which in turn establishes an HTTPS connection between the communication card and the BIP platform. The communication card and the BIP platform then exchange data through a secure data channel established by this connection. Further, if there is no subsequent data exchange, the BIP platform sends a No-Content message to the communication card. Upon receiving the No-Content message, the communication card sends a Close Channel command to the terminal, closing the BIP connection.

[0076] According to current standards, a communication card can only handle one HTTPS connection. If the communication card has already established an HTTPS connection, and the BIP platform initiates another connection establishment request, the request will fail, and no response notification will be sent to the BIP platform. This makes the BIP platform unaware of the connection status of the communication card, especially in a dual-BIP platform architecture, such as... Figure 3 As shown, BIP platform 1 has established a BIP connection, but BIP platform 2's request to establish a BIP connection fails, and the reason is unclear, making BIP capabilities of BIP platform 2 unavailable.

[0077] On the other hand, anomalies (such as network outages) may occur during BIP interaction, causing the BIP connection to be interrupted. The current mechanism is that in the event of an abnormal network outage, the BIP platform times out and disconnects the BIP connection, and the terminal sends a Channel Status (Link Dropped) Event to notify the communication card (e.g., ...). Figure 2 The exception handling process shown is that the communication card processes the event and closes the BIP connection. However, actual testing revealed inconsistent support for this event across terminals. If the terminal does not send a Channel Status (Link Dropped) Event during an abnormal network disconnection, the BIP platform disconnects the BIP connection while the communication card's state remains unchanged. This causes the BIP connection states of the BIP platform and the communication card to become out of sync. The BIP platform's re-request for the BIP connection fails, resulting in an unrecoverable BIP exception. Figure 4 As shown.

[0078] In summary, the current BIP mechanism has the following problems: 1) It lacks a mechanism for forcibly closing BIP connections, causing BIP anomalies to become unrecoverable; 2) It lacks a mechanism for synchronizing BIP connection states, causing the BIP platform to fail to establish BIP connections. To address these issues, the following technical solutions are proposed in this application. These solutions enhance BIP by introducing a mechanism for forcibly recovering from BIP anomalies and a mechanism for synchronizing BIP connection states.

[0079] To facilitate understanding of the technical solutions of the embodiments of this application, the technical solutions of this application are described in detail below through specific embodiments. The above-mentioned related technologies are optional solutions and can be arbitrarily combined with the technical solutions of the embodiments of this application, all of which fall within the protection scope of the embodiments of this application. The embodiments of this application include at least some of the following contents.

[0080] The technical solution of this application embodiment enhances BIP. On one hand, it adds a command to force close the BIP connection so that, in abnormal situations, the platform can restore the BIP connection by sending a data SMS carrying the command to close the BIP connection. On the other hand, it realizes the synchronization of the BIP connection status between the platform and the communication card. This will be described below.

[0081] It should be noted that the description of "BIP connection" in the following description can also be replaced with "HTTPS connection", "Transport Layer Security Session (TLS session)", or "HTTPS session (HTTPS session)".

[0082] BIP Enhancement Protocol - Parameters for Forcibly Closing a BIP Connection

[0083] The international standard Global Platform Card Specification Amendment B defines the parameters carried in SMS messages triggered by the BIP protocol, as shown in Table 1 below.

[0084]

[0085] Table 1

[0086] The technical solution of this application embodiment enhances the parameters shown in Table 1. Specifically, a new parameter is introduced, namely, the parameter for forcibly closing the BIP connection (also known as the parameter for forcibly closing the HTTPS connection). The new parameter can also be called a command to forcibly close the BIP connection. As one implementation, this new parameter is Tag=82 (i.e., tag value 82). Tag=82 and Tag=81 are shown in Table 2 below.

[0087] Label Length Name ‘81’ 0-n Administration session triggering parameters ‘82’ 00 Close tls session

[0088] Table 2

[0089] Here, "close TLS session" can also be understood as "close BIP connection", "close HTTPS connection", or "close HTTPS session".

[0090] BIP Enhancement Protocol - Connection Status Notification Parameters

[0091] The BIP platform triggers the establishment of a BIP connection by sending a data SMS (i.e., a trigger SMS). If the communication card has already established a BIP connection, the communication card notifies the BIP platform by replying with a Proof of Receipt (POR) command (i.e., response data). The structure of the response data is shown in Table 3 below.

[0092]

[0093] Table 3

[0094] The technical solution of this application embodiment enhances the parameters shown in Table 3 by introducing new response data, namely, response status codes. As one implementation method, the values ​​and meanings of the response status codes are shown in Table 4 below.

[0095] Value Meaning 01 Current tls session is executing 02 Tls session is closed 03 Parameter error

[0096] Table 4

[0097] Figure 5 This is a flowchart illustrating the interaction method based on enhanced BIP provided in the embodiments of this application. Figure 1 This method is applied to communication cards, such as... Figure 5 As shown, the interaction method based on enhanced BIP includes the following steps:

[0098] Step 501: Obtain the trigger SMS.

[0099] In this embodiment of the application, the communication card receives an APDU command; 1) if the APDU command is a trigger SMS command, then the trigger SMS is obtained from the trigger SMS command; 2) if the APDU command is a terminal response command, then it is determined whether the communication card has cached a trigger SMS, and if so, the cached trigger SMS is obtained.

[0100] Step 502: Determine whether the triggering SMS carries a first parameter and a second parameter, wherein the first parameter is used to trigger the establishment of a BIP connection, and the second parameter is used to indicate the closure of the BIP connection.

[0101] In this embodiment, the first parameter is tag value 81, and the second parameter is tag value 82, as shown in Table 2 above. Here, the first parameter can be understood as a command to establish a BIP connection, and the second parameter can be understood as a command to close a BIP connection.

[0102] It should be noted that the description of "BIP connection" can also be replaced with "HTTPS connection", "TLS session" or "HTTPS session".

[0103] In some optional implementations, before determining whether the trigger SMS carries the first parameter and the second parameter, the communication card determines whether the processing program is in an available state; wherein, if the processing program is in an available state, the step of determining whether the trigger SMS carries the first parameter and the second parameter is executed; if the processing program is in an unavailable state, the trigger SMS is cached. Here, as an example, the processing program can be a proactive handler.

[0104] Step 503: Interact with the terminal and / or BIP platform based on the judgment result.

[0105] In this embodiment of the application, the communication card interacts with the terminal and / or BIP platform based on the judgment result. The interaction process is described in detail below in conjunction with different judgment results.

[0106] Branch 1

[0107] If the determination result is that the triggering SMS carries the first parameter and the second parameter, then a first POR command is sent to the BIP platform. The first POR command carries first response data, which is used to indicate that the parameter is incorrect.

[0108] In the above scheme, the first response data can correspond to status code 03 in Table 4.

[0109] Branch Two

[0110] If the determination result is that the trigger SMS carries the first parameter, then determine whether there is an established BIP connection;

[0111] Branch 2-1) If an established BIP connection exists, send a second POR command to the BIP platform. The second POR command carries second response data, which is used to indicate that an established BIP connection exists.

[0112] Branch 2-2) If no BIP connection has been established, process the trigger SMS to establish a BIP connection.

[0113] In the above solution, determining whether an established BIP connection exists can be replaced by determining whether a TLS session is currently in operation.

[0114] In the above scheme, the second response data can correspond to status code 01 in Table 4.

[0115] In the above scheme, the step of processing the trigger SMS to establish a BIP connection includes: the communication card sending a BIP channel open command to the terminal, the BIP channel open command being used to trigger the terminal to establish a BIP connection between the communication card and the BIP platform, such as... Figure 2 Steps 204 to 207 are shown. Further, in some optional embodiments, after establishing a BIP connection, data interaction between the communication card and the BIP platform is completed through the BIP connection (e.g., ...). Figure 2 After steps 208 to 215 (as shown), the communication card sends a BIP channel close command to the terminal. This BIP channel close command triggers the terminal to close the BIP connection. Here, the BIP channel open command is also known as the Open Channel command, and the BIP channel close command is also known as the Close Channel command.

[0116] Branch 3

[0117] If the determination result is that the trigger SMS carries the second parameter, then determine whether there is an established BIP connection;

[0118] Branch 3-1) If an established BIP connection exists, a command to close the BIP channel is sent to the terminal. The command to close the BIP channel is used to trigger the terminal to close the BIP connection. A third POR command is also sent to the BIP platform. The third POR command carries third response data, which is used to indicate that the BIP connection has been closed.

[0119] Branch 3-2) If no established BIP connection exists, a third POR command is sent to the BIP platform. The third POR command carries third response data, which indicates that the BIP connection has been closed.

[0120] In the above solution, determining whether an established BIP connection exists can be replaced by determining whether a TLS session is currently in operation.

[0121] In the above scheme, the third response data can correspond to status code 02 in Table 4.

[0122] Branch 4

[0123] If the determination result is that the triggering SMS does not carry the first parameter and the second parameter, then a first POR command is sent to the BIP platform. The first POR command carries first response data, which is used to indicate that the parameters are incorrect.

[0124] In the above scheme, the first response data can correspond to status code 03 in Table 4.

[0125] Figure 6 This is a flowchart illustrating the interaction method based on enhanced BIP provided in the embodiments of this application. Figure 2 This method is applied to communication cards, such as... Figure 6 As shown, the interaction method based on enhanced BIP includes the following steps:

[0126] Step 601: The communication card receives an APDU command. If the APDU command is a trigger SMS command, proceed to step 602. If the APDU command is a terminal response command, proceed to step 613.

[0127] Step 602: The communication card receives the trigger SMS command.

[0128] Step 603: Determine if the active processing procedure is available. If it is not available, proceed to step 604. If it is available, proceed to step 605.

[0129] Step 604: Cache the triggered SMS message, skip to step 621.

[0130] Here, for BIP-triggered SMS messages, only the latest one is cached.

[0131] Step 605: Determine whether the triggered SMS message carries parameters 81 and 82. If yes, proceed to step 606; otherwise, proceed to step 607.

[0132] Step 606: Return to the POR command, carrying response data 03, and jump to step 621.

[0133] Step 607: Determine whether the triggered SMS message carries parameter 81. If yes, proceed to step 608; otherwise, proceed to step 615.

[0134] Step 608: Determine if there is an ongoing TLS session. If yes, proceed to step 609; otherwise, proceed to step 610.

[0135] Step 609: Do not cache the triggered SMS, return POR with response data 01, and jump to step 621.

[0136] Step 610: Process the triggered SMS and send an active command to Open Channel to establish a BIP connection.

[0137] Step 611: Complete BIP data interaction based on BIP connection.

[0138] Step 612: Send the active command Close Channel to close the BIP connection, then skip to step 621.

[0139] Step 613: Receive terminal response command.

[0140] Step 614: Determine if there is a cached trigger SMS. If there is, proceed to step 605; otherwise, proceed to step 621.

[0141] Step 615: Determine whether the triggered SMS carries parameter 82. If not, proceed to step 616; if yes, proceed to step 617.

[0142] Step 616: Return to the POR command, carrying response data 03, and jump to step 621.

[0143] Step 617: Determine if there is an ongoing TLS session. If yes, proceed to step 618; otherwise, proceed to step 620.

[0144] Step 618: Close the TLS session.

[0145] Step 619: Send the active command Close Channel to close the BIP connection.

[0146] Step 620: Return the POR command with response data 02, notify the BIP platform that the TLS session has been closed, and jump to step 621.

[0147] Step 621: End the processing flow.

[0148] The technical solution of this application embodiment supports, on the one hand, the command to force close BIP connection, which can force the recovery of abnormal BIP connection and improve the service experience; on the other hand, it supports connection status synchronization, supports multi-BIP platform architecture, and improves the success rate of BIP protocol processing.
