[0033] Through the above-mentioned drawings, specific embodiments of the present application have been shown, and there will be more detailed descriptions hereinafter. These drawings and text descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed Embodiments

[0034] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0035] To clearly understand the technical solution of the present application, the solutions of the prior art will be introduced in detail first. With the development of communication technology, eUICC cards are increasingly widely used in mobile terminal devices. The MEP (Multiple Enabled Profiles) function allows multiple LSIs (Logical Security Interfaces) to be implemented on the eUICC card. Each LSI can store a profile, enabling the simultaneous activation of multiple profiles. One profile is associated with one number, providing users with more flexible communication options. The implementation of this mechanism requires knowing in advance the port number of the LSI where the activated profile is located on the eUICC card, for sending instructions to different profiles for operation. In the prior art, the mechanism for obtaining this information is proprietary and lacks a unified standard protocol. Therefore, there are certain limitations in the current baseband chips in obtaining the LSI port numbers supported by the eUICC card and the corresponding profile information.

[0036] To solve the above technical problems, the inventors thought of enabling the baseband chip to obtain the LSI port numbers supported by the eUICC card and the corresponding profile information through a standardized mechanism, so as to efficiently send instructions to different LSIs.

[0037] Based on the above creative findings, the inventors proposed the technical solution of the present application.

[0038] The technical solution of the present application and how the technical solution of the present application solves the above technical problems will be described in detail below with specific embodiments. These several specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0039] Figure 1 It is a schematic diagram of the scenario of the information interaction method provided by the embodiment of the present application. As Figure 1 shown, the specific application scenarios of the embodiments of the present application include: an embedded universal integrated circuit card eUICC card 101 and a baseband chip 102.

[0040] Among them, the eUICC card is a smart card technology designed to meet the needs of communication connection management for devices in fields such as the Internet of Things. It integrates the functions of a traditional SIM card into an embedded chip inside the device. It uses integrated circuit technology to integrate a microprocessor, a storage unit, a communication interface, etc. on a small chip. Through the built-in operating system and communication protocols, the eUICC card can interact with other hardware and software modules of the device to achieve functions such as connection to a communication network, authentication, and data transmission.

[0041] The baseband chip is an integrated circuit chip used to process baseband signals in wireless communication. The baseband signal refers to the original unmodulated signal from the information source, which contains digital data, control information, etc. Its principle is to encode, modulate, etc. the original digital data at the sending end to convert it into an analog signal suitable for transmission over a wireless channel; at the receiving end, the received analog signal is demodulated, decoded, etc. to restore the original digital data, thereby realizing data interaction between the communication device and the network.

[0042] Specifically, the eUICC card 101 and the baseband chip 102 establish an electrical connection through a preset power supply circuit. The baseband chip 102 provides a stable operating voltage for the eUICC card 101 through a power supply control signal. After the eUICC card 101 receives this voltage and completes the power-on operation, it returns ATR (Answer To Reset) information to the baseband chip 102. The baseband chip 102 determines whether the eUICC card 101 supports the Multiple Active Profile (MEP) function based on this ATR information. If it is determined that the eUICC card 101 supports this function, the baseband chip 102 will send PPS (Protocol and Parameter Selection) to the eUICC card 101. The eUICC card 101 receives this PPS and responds to confirm that both communication parties support the MEP function. After that, the baseband chip 102 sends a configuration status acquisition instruction to the eUICC card 101. The eUICC card 101 sends the status instruction return information containing the activated profile information and the LSI (Logical Security Interface) port number corresponding to this profile information to the baseband chip 102 according to this instruction. The baseband chip 102 sends an instruction to the LSI through an APDU (Application Protocol Data Unit) instruction based on this status instruction return information, and then executes the management of the profile information of the configuration file.

[0043] Figure 2 It is a schematic flowchart of the information interaction method provided by the embodiment of this application, as Figure 2As shown, the execution entity of this method can be an eUICC card as shown in Figure 1 , or other devices with similar functions. This method includes:

[0044] S201: Receive the stable operating voltage provided by the baseband chip through the power supply control signal, complete the power-on operation, and return the reset response ATR information, so that the baseband chip can determine whether the eUICC card supports the multi-activation profile MEP function according to the ATR information.

[0045] Among them, the ATR information is an identification information of the eUICC card, which contains relevant parameters such as the functions supported by the card and the communication protocol. The baseband chip can determine whether the eUICC card supports the multi-activation profile function according to this ATR information.

[0046] Specifically, the eUICC card receives the stable operating voltage provided by the baseband chip through the power supply control signal and completes the power-on operation. After power-on, the eUICC card will return the reset response information to the baseband chip.

[0047] S202: If it supports the MEP function, receive the protocol parameter selection PPS sent by the baseband chip and respond to the PPS to confirm that both communication parties support the MEP function.

[0048] Among them, the PPS is used to negotiate and determine the communication protocol and parameters between the eUICC card and the baseband chip, such as the data transmission rate, communication mode, etc. Through the interaction and confirmation of the PPS by both parties, it is ensured that both parties use the same protocol and parameters in the subsequent communication process.

[0049] Specifically, if the baseband chip determines that the eUICC card supports the MEP function according to the ATR information, it will send the PPS to the eUICC card, and after receiving the PPS, the eUICC card will respond to it.

[0050] S203: Receive the configuration status acquisition instruction sent by the baseband chip.

[0051] Among them, in order to understand the currently activated profile information in the eUICC card, the baseband chip will send the configuration status acquisition instruction. This instruction is a request from the baseband chip to initiate the configuration file management operation of the eUICC card. After receiving this instruction, the eUICC card needs to perform corresponding processing according to the requirements of the instruction.

[0052] Specifically, the configuration status acquisition instruction is defined as 80 7D 00 00 00.

[0053] Exemplarily, when the baseband chip actively sends a configuration status acquisition instruction GET_PROFILE_STATUS to obtain the activated profile and the corresponding LSI port number, the return format of the eUICC card can be: 80 (tag value) + L1 (length of value1) + value1 + 80 (tag value) + L2 (length of value2) + value2 +...

[0054] Among them, the tag value 80 serves as the tag value. After each 80, there is immediately a data value length, followed by the specific value containing the ICCID identification of any activated profile and the corresponding LSI port number. This structure can appear repeatedly, that is, through multiple combinations of 80 + L n (value n ) + value n , the relevant information of multiple activated profiles can be listed in sequence.

[0055] S204: According to the configuration status acquisition instruction, send the status instruction return information to the baseband chip, so that the baseband chip, based on the status instruction return information, sends an instruction to the LSI through the application protocol data unit APDU instruction to perform the management of the profile information, where the status instruction return information includes the activated profile information and the logical security interface LSI port number corresponding to the profile information.

[0056] Among them, the APDU instruction usually consists of a command APDU and a response APDU. The command APDU is sent by an external device to the smart card to request the execution of a specific operation, and the response APDU is the response of the smart card to the command APDU.

[0057] Specifically, the eUICC card sends the status instruction return information to the baseband chip according to the configuration status acquisition instruction. The status instruction return information includes the activated profile information and the LSI port numbers corresponding to these profile information. After receiving this information, the baseband chip sends an instruction to the LSI through the APDU instruction to perform the management of the profile information.

[0058] In summary, during the interaction between the eUICC card and the baseband chip, the eUICC card first receives the stable operating voltage provided by the baseband chip's power supply control signal to complete power-on, and returns the ATR information for the baseband chip to determine whether it supports the MEP function; if it supports, the eUICC card receives the PPS and responds to confirm that both parties support the MEP function; then the eUICC card receives the configuration status acquisition instruction, and then sends the status instruction return information containing the activated profile information and the corresponding LSI port number to the baseband chip. Based on this, the baseband chip sends an instruction to the LSI through the APDU instruction to manage the configuration file. This series of steps enables the baseband chip to accurately obtain the LSI port numbers supported by the eUICC card and the corresponding profile information through a standardized mechanism, realizing the efficient sending of instructions to different LSIs, which not only improves the communication efficiency and reliability between the baseband chip and the eUICC card, but also reduces the complexity of development and maintenance.

[0059] In another embodiment provided by the present application, since the profile of the eUICC can be downloaded, deleted, disabled, activated and other operations by the LPA (Local Profile Assistant) application on the terminal, when the profile of the eUICC card changes, the eUICC card needs to actively send an instruction to inform the baseband chip of the current status. Taking the example that there is a disabled profile on the eUICC card, the method includes:

[0060] Sa1: When the baseband chip is using the eUICC card to access the network normally, if it detects that any profile information is disabled, it sends the information to be returned to the baseband chip, so that the baseband chip sends an acquisition instruction to the eUICC card, where any profile information is associated with a number used for network connection.

[0061] Specifically, during the process of the baseband chip using the eUICC card to connect to the network, that is, during the process of accessing the network, the eUICC card will monitor the status of its own profile in real time. When the eUICC card detects that any one of the profile information is disabled, the eUICC card will actively notify the baseband chip that there is information to be returned. The baseband chip will send an acquisition instruction to the eUICC card.

[0062] Among them, any profile information is associated with a number used for network connection, that is, each profile corresponds to a specific number that can be used for network connection.

[0063] Sa2: Receive the acquisition instruction sent by the baseband chip and send a profile disable instruction to the baseband chip, where the profile disable instruction includes any profile information and the LSI port number corresponding to any profile information, so that the baseband chip performs an operation to disconnect the network connection of the number.

[0064] Specifically, after the eUICC card receives the acquisition instruction sent by the baseband chip according to the information to be returned, it will send a profile disable instruction, the PROFILE_ACTIVATED instruction, to the baseband chip. This profile disable instruction contains any profile information to be disabled and the LSI port number corresponding to this profile information. After receiving this information, the baseband chip will perform an operation to disconnect the network connection of the number associated with this profile. That is to say, the baseband chip will, according to the received disable instruction and related information, cut off the network connection of the number corresponding to the disabled profile to prevent communication failures caused by using the disabled profile for network connection.

[0065] Specifically, the profile disable instruction uses 48 as the tag value, followed by the content length and the content. The content is: 80 (tag value) + L1 (length of value1) + value1 + 80 (tag value) + L2 (length of value2) + value2 +...

[0066] Among them, the tag value 80 is used as the tag value. After each 80, there is immediately a data value length, and then the specific value containing the ICCID identification of any activated profile and the corresponding LSI port number. This structure can appear repeatedly, that is, through the combination of multiple 80 + L n (value n ) + value n , the relevant information of multiple activated profiles can be listed in sequence.

[0067] In summary, in the interaction between the eUICC card and the baseband chip, when the eUICC card detects that a profile is disabled, it will first send the information to be returned, which causes the baseband chip to send an acquisition instruction; after receiving the instruction, the eUICC card then sends a profile disable instruction containing the disabled profile and the LSI port number, enabling the baseband chip to disconnect the network connection of the corresponding number. By promptly disconnecting the invalid network connection due to profile disablement, network anomalies and data transmission errors are avoided, ensuring the stable operation of network communication. At the same time, by preventing illegal or invalid profiles from being used for network connection, security risks are reduced, and the stability and security of network communication can be improved.

[0068] In another embodiment provided by the present application, since the profile of the eUICC can be downloaded, deleted, disabled, activated and other operations by the LPA (Local Profile Assistant) application on the terminal, when the profile of the eUICC card changes, the eUICC card needs to actively send instructions to inform the baseband chip of the current state. Taking the activation of the profile on the eUICC card as an example, the method includes:

[0069] Sb1: When the baseband chip is normally using the eUICC card to access the network, if it detects that any profile information is activated, it sends new activation information to the baseband chip, so that the baseband chip sends a query instruction to the eUICC card.

[0070] Specifically, during the process of the baseband chip normally using the eUICC card for network login, that is, during the process of accessing the network, the eUICC card continuously monitors the status change of its own profile. When the eUICC card detects that any one of the profile information is activated, the eUICC card actively sends new activation information to the baseband chip. The purpose of this new activation information is to notify the baseband chip that a new profile of the current eUICC card has been activated, thereby prompting the baseband chip to send a query instruction to the eUICC card in order to further obtain detailed information about the newly activated profile.

[0071] Sb2: Receive the query instruction sent by the baseband chip, and send a new activation instruction to the baseband chip, where the new activation instruction includes any profile information and the LSI port number corresponding to any profile information, so that the baseband chip performs network access operations on the number associated with any profile information.

[0072] Specifically, after the eUICC card receives the query instruction sent by the baseband chip according to the new activation information, it sends a new activation instruction to the baseband chip. This new activation instruction contains any activated profile information and the LSI port number corresponding to the profile information. After receiving these detailed information, the baseband chip can perform network access operations on the number associated with the profile information. That is to say, the baseband chip will use the newly activated profile and its related information to try to let the number associated with it access the network and realize the communication function.

[0073] In summary, in the collaborative workflow between the eUICC card and the baseband chip, when the eUICC card detects that a profile is activated, it first sends new activation information to the baseband chip, prompting the baseband chip to send a query instruction. After receiving the query instruction, the eUICC card sends a new activation instruction containing the activated profile information and the corresponding LSI port number back to the baseband chip, so that the baseband chip can perform network registration operations on the associated number. By avoiding the baseband chip's blind detection of the eUICC card status and reducing invalid operations, it is possible to quickly establish a network connection based on the newly activated profile and improve data transmission efficiency.

[0074] The present application also provides another method for the information interaction method. The execution subject of this method can be a baseband chip as shown in Figure 1 or other devices with similar functions. This method includes:

[0075] S301: Provide a stable operating voltage through a power supply control signal to complete the power-on operation of the eUICC card.

[0076] Specifically, the baseband chip provides a stable operating voltage to the eUICC card through the power supply control signal. After obtaining stable power supply, the eUICC card can perform subsequent initialization and other operations, thereby completing the power-on operation.

[0077] S302: Receive the reset response ATR information sent by the eUICC card and determine whether the eUICC card supports the multi-activation profile MEP function.

[0078] Specifically, after the eUICC card completes the power-on operation, it sends ATR information to the baseband chip. The baseband chip receives this ATR information and parses it. By parsing the relevant parameters and identifiers in the ATR information, the baseband chip determines whether the eUICC card supports the MEP function.

[0079] S303: If the eUICC card supports the MEP function, send the protocol parameter selection PPS to the eUICC card to make the eUICC card respond to the PPS, and both communication parties support the MEP function.

[0080] Specifically, if the baseband chip determines that the eUICC card supports the MEP function, then the baseband chip sends PPS to the eUICC card. After receiving the PPS, the eUICC card processes it and responds to the baseband chip. Through this interaction process, both parties confirm that they both support the MEP function and reach an agreement on the communication protocol and parameters.

[0081] S304: Send a configuration status acquisition instruction to the eUICC card to make the eUICC card generate status instruction return information according to the configuration status acquisition instruction and send it to the baseband chip.

[0082] Specifically, after confirming that both parties support the MEP function, the baseband chip sends a configuration status acquisition instruction to the eUICC card. After receiving this instruction, the eUICC card generates status instruction return information according to the requirements of the instruction. This information includes the profile information activated in the current eUICC card and the LSI port numbers corresponding to these profile information. Then the eUICC card sends the generated status instruction return information to the baseband chip.

[0083] S305: Receive the status instruction return information sent by the eUICC card, send an instruction to the LSI through the Application Protocol Data Unit (APDU) instruction, and perform the management of the profile information, where the status instruction return information includes the activated profile information and the logical security interface (LSI) port number corresponding to the profile information.

[0084] Specifically, after the baseband chip receives the status instruction return information sent by the eUICC card, according to the activated profile information and the corresponding LSI port numbers included therein, it sends an instruction to the LSI through the APDU instruction. These instructions are used to perform management operations on the profile information, such as activating a new profile, disabling certain profiles, querying detailed information of profiles, etc.

[0085] In summary, during the interaction between the eUICC card and the baseband chip, the eUICC card first receives the stable working voltage provided by the baseband chip's power supply control signal to complete power-on, and returns the ATR information for the baseband chip to determine whether it supports the MEP function; if it supports, the eUICC card receives the PPS and responds to confirm that both parties support the MEP function; then the eUICC card receives the configuration status acquisition instruction, and then sends the status instruction return information containing the activated profile information and the corresponding LSI port numbers to the baseband chip. The baseband chip then sends instructions to the LSI through the APDU instruction to manage the profiles. This series of steps enables the baseband chip to accurately obtain the LSI port numbers supported by the eUICC card and the corresponding profile information through a standardized mechanism, realizes efficiently sending instructions to different LSIs, not only improves the communication efficiency and reliability between the baseband chip and the eUICC card, but also reduces the complexity of development and maintenance.

[0086] Figure 3 For the interaction flowchart of the information interaction method provided by the embodiment of the present application, as Figure 3 shown, the method includes:

[0087] S401: The baseband chip provides a stable working voltage for the eUICC card through the power supply control signal, and the eUICC card completes power-on.

[0088] S402: The eUICC card returns the ATR information to the baseband chip.

[0089] Specifically, the baseband chip is informed by the ATR information that the eUICC card supports the MEP function.

[0090] S403: The baseband chip sends the PPS to the eUICC card.

[0091] Among them, the PPS is used to inform the eUICC card that it also supports the MEP function.

[0092] S404: The eUICC card responds to the PPS.

[0093] Specifically, the eUICC card responds to determine that both communication parties support the MEP function.

[0094] S405: The baseband chip sends a configuration status acquisition instruction to the eUICC card.

[0095] S406: The eUICC card returns the profile information and the corresponding LSI port number to the baseband chip.

[0096] S407: According to the obtained profile information and the corresponding LSI port number, the baseband chip sends an instruction to the corresponding LSI through an APDU command to implement the management of different profiles.

[0097] In summary, during the interaction between the eUICC card and the baseband chip, the eUICC card first receives the stable working voltage provided by the baseband chip's power supply control signal to complete power-on, and returns the ATR information for the baseband chip to determine whether it supports the MEP function; if it supports, the eUICC card receives the PPS and responds to confirm that both parties support the MEP function; then the eUICC card receives the configuration status acquisition instruction, and then sends the status instruction return information containing the activated profile information and the corresponding LSI port number to the baseband chip. The baseband chip then sends an instruction to the LSI through an APDU instruction to manage the configuration file. This series of steps enables the baseband chip to accurately obtain the LSI port number and the corresponding profile information supported by the eUICC card through a standardized mechanism, and realize the efficient sending of instructions to different LSIs, which not only improves the communication efficiency and reliability between the baseband chip and the eUICC card, but also reduces the complexity of development and maintenance.
