Fig. 3 is a flowchart of a method for implementing one-card multi-number according to an embodiment of the present application, where, as shown in fig. 3, the method may include:

Step 301, the terminal equipment acquires a user instruction.

The user instruction may include first indication information, where the first indication information may be used to indicate a channel associated with the user instruction.

The user instruction may be an application protocol data unit (application protocol data unit, APDU) instruction (command APDU), for example. The first indication information may be a Class (CLA) field in the APDU instruction.

As shown in fig. 4, the APDU instruction may include a Header (Header) field, which may include a CLA field, an INS field, a P1 field, and a P2 field.

The CLA field is an instruction type field, and may be used as first indication information or include first indication information to indicate which channel the current user instruction is a user instruction associated with, the INS field is an instruction code, and the P1 field and the P2 field are parameter fields.

For example, taking an example in which the subscriber identity card includes 16 channels (e.g., channel 0 through channel 15), the channels 0 through 15 of the subscriber identity card may be indicated by setting the first indication information to 4 bits.

Optionally, as shown in fig. 4, the APDU instruction further includes a body (body) field, wherein the body field may include an Lc field, a data field (data field) field, and a Le field.

Wherein, the Lc field is the length field of data; the data field (Le) field is used to store data, and the Le field is the number of data bytes that are answered when a response is desired.

Optionally, the terminal device obtains the user instruction from the application, or the terminal device obtains the user instruction from an application server in the data network.

Step 302, the terminal device sends a user instruction to the user identity card through the baseband processor.

The terminal device may include a plurality of baseband processors, and the subscriber identity card may include a plurality of channels and a plurality of subscriber numbers, where different channels are associated with different subscriber numbers, and different channels are associated with different baseband processors.

The terminal equipment can determine a channel associated with the current user instruction according to the first indication information in the user instruction, determine a baseband processor associated with the channel according to the channel, and send the current user instruction to the user identity card through the determined baseband processor.

For example, as shown in fig. 1, taking an example that the first indication information in the user instruction 1 received by the terminal device indicates the channel 1, the terminal device may send the user instruction 1 to the user identity card through the baseband processor 1 associated with the channel 1.

Optionally, the terminal device communicates with the subscriber identity card through a baseband chip, as shown in fig. 5, where the baseband chip may include a plurality of baseband processors and a subscriber identity card data processing circuit.

The baseband processor is used for processing radio frequency signals and communicating with the user identity identification card to perform identity authentication service of the mobile network. The user identification card data processing circuit is responsible for processing the clock and reset signals sent to the user identification card, reading the information in the user identification card and transmitting the information to the baseband processor.

Optionally, the terminal device further comprises a first application, where the first application is configured to instruct the baseband processor to associate with the channel.

The terminal device may set a channel associated with the baseband processor through the first application.

Illustratively, the channel associated with baseband processor 1 may be set to channel 1 and the channel associated with baseband processor 2 may be set to channel 2 by the first application.

Optionally, the first application is further configured to set the user number, such as setting the user number as a primary number (or described as a primary card) or a secondary number (or described as a secondary card).

Optionally, the first application may also incorporate functionality of the terminal software (local profile assistant, LPA).

The LPA is used for performing management tasks such as downloading, viewing, activating, disabling and the like of the subscription information of the user.

Step 303, the user identification card sends a user instruction to the user number through the channel.

When the user identification card receives a user instruction sent by the terminal equipment through the baseband processor, a channel associated with the user instruction can be determined according to the user instruction, a user number associated with the channel is determined according to the channel, and then the received user instruction is sent to the user number.

For example, as shown in fig. 7, taking a subscriber identity card as an eUICC card, the eUICC card may include a plurality of ISD-ps, where each ISD-P may store one subscriber subscription information (each subscriber subscription information corresponds to one subscriber number); ISD-R is responsible for downloading, activating and other work for managing subscription information of users; ECASD stores certificate and takes charge of relevant security authentication work; the telecommunications framework (telecom framework) provides standard network authentication services; the package parser (profile package interpreter) is responsible for parsing the downloaded files (profiles) and generating user subscription information. These subscriber subscriptions may be managed by the LPA in charge of downloading, viewing, activating, disabling, etc. the available international specifications.

In the embodiment of the application, the user identification card can activate the acquired plurality of user numbers simultaneously (or the user identification card can have a plurality of user numbers on the internet at the same time) by adjusting the card software of the user identification card.

Alternatively, the subscriber identity card may also set the activated subscriber number as a primary card or a secondary card, e.g. a plurality of subscriber numbers are set as primary card, secondary card 1, secondary card 2, secondary card 3, etc., respectively.

Illustratively, the subscriber identity card may set the channel associated with the primary card to channel 0 (or described as a basic channel), set the channel associated with the secondary card 1 to channel 1 (or described as a logical channel 1), set the channel associated with the secondary card 2 to channel 2, and so on. When the user identification card sends user instructions to the user numbers, all issued 0-channel instructions are sent to the main card, all issued 1-channel instructions are sent to the auxiliary card 1, so that the activated user numbers are ensured not to be affected each other.

Optionally, the channel with the associated user number is in an occupied state, and the other user numbers are not allowed to be used.

Based on the method shown in fig. 6, in one user identification card, different user numbers can be associated with different channels, that is, user instructions corresponding to different user numbers can be transmitted to different user numbers through different channels, and as communication between the channels is not affected, communication between the user numbers is not affected, so that a plurality of user numbers which are not affected can be used in one user identification card at the same time.

Because the space of the user identity card can reach 1.2M, single user subscription information is estimated to be about 50k, based on the method shown in the above figure 6, the card space of the user identity card can be fully utilized, a plurality of user subscription information can be stored in one user identity card, dynamic downloading of the user subscription information is carried out through the internationally universal GSMA eUICC technology, and a plurality of user numbers can be used simultaneously according to the terminal equipment capability.

In addition, in the method shown in fig. 6, while implementing a plurality of subscriber numbers in a single subscriber identity module card, the method can also implement simultaneous standby or simultaneous communication of a plurality of subscriber numbers according to the capability of the terminal device, and can also implement dual-card dual-standby/dual-card dual-pass, etc., thereby saving a card slot circuit and reducing the number of subscriber identity modules; the new user number can be dynamically downloaded, the user number can be deleted, and the like, so that the user requirement can be met; and the modification amount is relatively small.

It should be noted that, the methods provided in the embodiments of the present application may be implemented separately or may be implemented in combination, and are not limited.

The embodiment of the application may divide the functional modules of each device according to the above method example, for example, each functional module may be divided corresponding to each function, or two or more functions may be integrated into one processing module. The integrated modules may be implemented in hardware or in software functional modules. It should be noted that, in the embodiment of the present application, the division of the modules is schematic, which is merely a logic function division, and other division manners may be implemented in actual implementation.
