The hardware part of the embedded SIM card includes a processor, an encryption/decryption unit, etc., and is usually in the form of a chip. The software part of the embedded SIM card runs on the hardware of the embedded SIM card, namely when the hardware of the embedded SIM card is powered on, the software part of the embedded SIM card runs on the hardware of the embedded SIM card.
The software of the embedded SIM card comprises an embedded SIM card operating system and a data security domain. The embedded SIM Card operating system contains the most basic Platform features and supports features defined in the Global Platform Card Specification (GPCS). The data Security Domain comprises an eUICC authentication authorization Security Domain (ECASD), a Certificate Issuer Root Security Domain (ISD-R) and a configuration file data Security Domain ISD-P (ISD-Profile), wherein the configuration file (Profile) is arranged in the ISD-P and can be activated or deactivated by a Security Domain mechanism.
In the prior art, actual user information is stored in the ISD-P, and one mobile phone number can be considered to be associated with one ISD-P. Multiple ISD-ps can be stored in the embedded SIM card, but existing protocols provide for only one to be activated at a time. As shown in fig. 1, 3 ISD-ps are saved in the embedded SIM card, but only one ISD-P is in enabled state and the other two ISD-ps are in disabled state.
That is, although a plurality of mobile phone numbers may be included in the embedded SIM card, only one is in use at a time. In other words, at the same time, the embedded SIM card only allows one of the profiles to be activated, and cannot access multiple profiles at the same time, that is, cannot support simultaneous access of multiple numbers.

When an access instruction for accessing the embedded SIM card is received, selecting a data security domain corresponding to the identifier of the embedded SIM card corresponding to the access instruction in an embedded SIM card operating system according to the identifier of the embedded SIM card corresponding to the access instruction, so that the data security domains corresponding to different embedded SIM cards can be accessed at the same time, and the simultaneous access of multiple numbers is supported.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
In the specific implementation, the architecture of the embedded SIM card provided in the embodiment of the present invention is described first.
In particular implementations, the embedded SIM card may include embedded SIM card hardware as well as embedded SIM card software. The hardware of the embedded SIM card may be substantially the same as that of the embedded SIM card provided in fig. 1, and also includes components such as a processor, an encryption/decryption unit, etc., and is in the form of a chip.
In terms of hardware, compared with the existing embedded SIM card, the embedded SIM card provided in the embodiments of the present invention may add an interface circuit, and identify operating systems corresponding to different embedded SIM cards through the interface circuit. In specific application, the interface circuit may be a plurality of sets of standard interface circuits, may also be a chip select input pin, and may also be a hardware circuit in other forms. The standard interface circuit can be an interface circuit corresponding to the standard of the existing embedded SIM card.
When the hardware of the embedded SIM card is powered on, the software of the embedded SIM card runs on the hardware of the embedded SIM card. In a specific implementation, when the hardware of the embedded SIM card is powered on, the operating system of the embedded SIM card runs on the hardware of the embedded SIM card. Different from the prior art, at least two data security domains corresponding to the embedded SIM cards run on the operating system of the embedded SIM card.
That is, in the prior art, a data security domain corresponding to an embedded SIM card is run on an embedded SIM card system running on embedded SIM card hardware. In the embodiment of the present invention, at least two data security domains corresponding to the embedded SIM cards run on an embedded SIM card system running on embedded SIM card hardware, and the data security domains corresponding to different embedded SIM cards are independent of each other.
In practical applications, a data security domain corresponding to the embedded SIM card includes: ECASD, ISD-R, and ISD-P. And aiming at different embedded SIM cards, the data in the corresponding data security domain is different. When the operating system of the embedded SIM card runs with data security domains corresponding to at least two embedded SIM cards, it means that the hardware of the same set of embedded SIM cards can implement the functions of multiple embedded SIM cards, that is, the hardware of the set of embedded SIM cards can correspond to multiple subscriber numbers.
It should be noted that, in the embodiment of the present invention, the embedded SIM card in the mobile terminal is only one set, that is, only one set of hardware of the embedded SIM card is included. The hardware corresponding to a plurality of embedded SIM cards, such as the embedded SIM card 1, the embedded SIM card 2, and the like, described below is the same set, and the SIM card 1 and the SIM card 2 are distinguished by different embedded SIM card data security domains.
For example, the embedded SIM card 1 corresponds to the embedded SIM card data security domain 1, the embedded SIM card 2 corresponds to the embedded SIM card data security domain 2, and the embedded SIM card 1 and the embedded SIM card 2 correspond to the same set of hardware of the embedded SIM card.
Referring to fig. 2, a structure diagram of an embedded SIM card in the embodiment of the present invention is shown. The embedded SIM card provided in fig. 2 includes a set of embedded SIM card hardware. When the embedded SIM card hardware is powered on, an embedded SIM card operating system runs on the embedded SIM card hardware. An embedded SIM card data security domain 1 corresponding to the embedded SIM card 1 and an embedded SIM card data security domain 2 corresponding to the embedded SIM card 2 are operated on the embedded SIM card operating system.
In an embodiment of the present invention, an embedded SIM card data security domain 1 includes: ECASD _1, ISD-R _1, ISD-P _1A, ISD-P _1B, and ISD-P _1C, wherein ISD-P _1A is in an enabled state and ISD-P _1B and ISD-P _1C are in a disabled state.

The data contained in the embedded SIM card data security domain 1 and the data contained in the embedded SIM card data security domain 2 correspond to different embedded SIM cards, respectively, so that the embedded SIM card in fig. 2 can implement the functions of the embedded SIM card 1 and the embedded SIM card 2.
It should be noted that, in a specific implementation, the number of the embedded SIM card data security domains running on the embedded SIM card operating system is not limited to two shown in fig. 2, and may also be three or more, and the embedded SIM card data security domains running on the embedded SIM card operating system may be set according to specific application requirements.
A method for accessing the embedded SIM card provided in fig. 2 by the mobile terminal is explained as follows.
Referring to fig. 3, a method for accessing an embedded SIM card according to an embodiment of the present invention is shown, and a structure of the embedded SIM card may be as shown in fig. 2. The following describes the embedded SIM card access method in detail through specific steps with reference to fig. 2.
Step S301, receiving an access instruction for accessing the embedded SIM card.
In a specific implementation, the embedded SIM card may be pre-installed in the mobile terminal. For example, when the mobile terminal is shipped, the embedded SIM card is soldered on a circuit board of the mobile terminal.
When the mobile terminal needs to acquire the user number or acquire the related information corresponding to the user number, the mobile terminal may send an access instruction to the embedded SIM card to access the embedded SIM card. In the embodiment of the invention, at least two embedded SIM card data security domains are operated on an embedded SIM card operating system operated on hardware of one embedded SIM card, and different embedded SIM card data security domains correspond to different user numbers, so that the mobile terminal can set the identification corresponding to the accessed embedded SIM card in the access instruction.
For example, on the embedded SIM card operating system, an embedded SIM card data security domain 1 corresponding to the embedded SIM card 1 and an embedded SIM card data security domain 2 corresponding to the embedded SIM card 2 are operated. The information corresponding to the user number 1 is stored in the ISP-P _1A of the embedded SIM card data security domain 1 in the starting state. The information corresponding to the user number 2 is stored in the ISP-P _2A of the embedded SIM card data security domain 2 in the enabled state.
Step S302, obtaining the identification of the embedded SIM card corresponding to the access instruction.
In a specific implementation, when the mobile terminal needs to acquire the related information of the user number 1 and the related information of the user number 2, the identifier S1 corresponding to the embedded SIM card 1 and the identifier S2 corresponding to the embedded SIM card 2 may be set in the access instruction to access the embedded SIM card 1 and the embedded SIM card 2.
Therefore, when the access instruction is received, the identifier of the embedded SIM card corresponding to the access instruction can be obtained from the access instruction. After the identification of the embedded SIM card is obtained from the access instruction, the user can know which embedded SIM card or embedded SIM cards the mobile terminal currently has the access requirement.
In the embodiment of the invention, the access to one embedded SIM card is substantially to access the corresponding embedded SIM card data security domain on the embedded SIM card operating system.
For example, accessing the embedded SIM card 1 substantially accesses the embedded SIM card data security domain 1 running on the embedded SIM card operating system, where the embedded SIM card data security domain 1 corresponds to the embedded SIM card 1.
Step S303, in the embedded SIM card operating system, according to the identifier of the embedded SIM card corresponding to the access instruction, selecting and accessing the embedded SIM card data security domain corresponding to the identifier of the embedded SIM card.
In specific implementation, the hardware of the existing embedded SIM card can be improved, and a plurality of standard interface circuits are added on the basis of the hardware of the existing embedded SIM card. And aiming at each standard interface circuit, respectively setting one-to-one corresponding embedded SIM card data security domains and one-to-one corresponding embedded SIM card identifiers. After receiving the access instruction, the bottom layer hardware of the mobile terminal can select a standard interface circuit corresponding to the identifier of the embedded SIM card according to the identifier of the embedded SIM card corresponding to the access instruction.
For example, the embedded SIM card operating system is run when power is on, using a set of embedded SIM card hardware. An embedded SIM card data security domain 1, an embedded SIM card data security domain 2 and an embedded SIM card data security domain 3 are respectively operated on the embedded SIM card operating system.
On the hardware of the embedded SIM card, 3 standard interface circuits are arranged, the 3 standard interface circuits are respectively a standard interface circuit 1, a standard interface circuit 2 and a standard interface circuit 3, and the 3 standard interface circuits are all coupled with the mobile terminal. The standard interface circuit 1 corresponds to the embedded SIM card data security domain 1 and corresponds to the identifier S1 of the embedded SIM card 1; the standard interface circuit 2 corresponds to the embedded SIM card data security domain 2 and corresponds to the identifier S2 of the embedded SIM card 2; the standard interface circuit 3 corresponds to the embedded SIM card data security domain 3 and to the identity S3 of the embedded SIM card 3.
When the mobile terminal has access requirements for the embedded SIM card 1 and the embedded SIM card 2, the sent access instruction carries the identifier S1 corresponding to the embedded SIM card 1 and the identifier S2 corresponding to the embedded SIM card 2. The bottom layer of the mobile terminal obtains the identifier S1 and the identifier S2 from the access command, and triggers the standard interface circuit 1 and the standard interface circuit 2, respectively. When detecting that the standard interface circuit 1 and the standard interface circuit 2 are triggered, the embedded SIM card operating system respectively sends the access instruction to the embedded SIM card security data field 1 and the embedded SIM card security data field 2, so that the mobile terminal can access the embedded SIM card 1 and the embedded SIM card 2.
In specific implementation, a plurality of chip selection input pins can be added on the basis of the hardware of the existing embedded SIM card. And respectively setting one-to-one corresponding embedded SIM card data security domains for each chip selection input pin. After receiving the access instruction, the bottom layer hardware of the mobile terminal can select a chip selection input pin corresponding to the identifier of the embedded SIM according to the identifier of the embedded SIM corresponding to the access instruction.
For example, the embedded SIM card operating system is run when power is on, using a set of embedded SIM card hardware. An embedded SIM card data security domain 1, an embedded SIM card data security domain 2 and an embedded SIM card data security domain 3 are respectively operated on the embedded SIM card operating system.
Adding a chip selection input pin 1, a chip selection input pin 2 and a chip selection input pin 3 on the hardware of the embedded SIM card, wherein the chip selection input pin 1 corresponds to the data security domain 1 of the embedded SIM card and the identifier S1 of the embedded SIM card 1; the chip selection input pin 2 corresponds to the embedded SIM card data security domain 2 and the identifier S2 of the embedded SIM card 2; the chip select input pin 3 corresponds to the embedded SIM card data security domain 3 and the identifier S3 of the embedded SIM card 3.
When the mobile terminal has access requirements on the embedded SIM card 1 and the embedded SIM card 3, the identifier S1 and the identifier S3 are carried in the sent access instruction. The bottom layer of the mobile terminal obtains the identifier S1 and the identifier S3 from the access command, and triggers the chip select input pin 1 and the chip select input pin 3, respectively. When detecting that the chip selection input pin 1 and the chip selection input pin 2 are triggered, the embedded SIM card operating system respectively sends the access instruction to the embedded SIM card security data field 1 and the embedded SIM card security data field 3, so that the mobile terminal can access the embedded SIM card 1 and the embedded SIM card 3.
In practical applications, the identity of the embedded SIM card may be a binary number. For example, the symbol S1 is represented by a binary number 00, the symbol S2 is represented by a binary number 01, and the symbol S3 is represented by a binary number 10.
In particular implementations, no modifications to the hardware of the embedded SIM card may be required. And when the embedded SIM card operating system receives the access instruction, the corresponding embedded SIM card data security domain can be selected according to the identification of the embedded SIM card in the access instruction.
For example, in the access instruction, the identifier S1 of the embedded SIM card 1 is carried, and after receiving the access instruction, the embedded SIM card operating system sends the access instruction to the embedded SIM card data security domain 1, so that the mobile terminal can access the embedded SIM card 1.
In the prior art, although a plurality of ISD-ps can be stored in the embedded SIM card, only one ISD-P is specified to be in an enabled state in the existing protocol. That is, although a plurality of mobile phone numbers may be included in the embedded SIM card, only one is in use at a time. In other words, at the same time, the embedded SIM card only allows one of the profiles to be activated, and cannot access multiple profiles at the same time, that is, cannot support simultaneous access of multiple numbers.
In the embodiment of the present invention, in the embedded SIM card operating system, data security domains corresponding to a plurality of embedded SIM cards run. When an access instruction for accessing the embedded SIM card is received, selecting a data security domain corresponding to the identifier of the embedded SIM card corresponding to the access instruction in an embedded SIM card operating system according to the identifier of the embedded SIM card corresponding to the access instruction, so that the data security domains corresponding to different embedded SIM cards can be accessed at the same time, and the simultaneous access of multiple numbers is supported.
That is to say, in the embodiment of the present invention, for a data security domain corresponding to one embedded SIM card, only one ISD-P is in the enabled state, and the rest ISD-ps are in the disabled state. However, since at least two embedded SIM data security domains are run on one embedded SIM operating system, the number of ISD-ps in the enabled state on one embedded SIM operating system is at least two. Therefore, the mobile terminal can access the data security domains corresponding to different embedded SIM cards at the same time, and further, the simultaneous access of multiple numbers is supported.
In the prior art, for a multi-card multi-standby mobile terminal, because one embedded SIM card can only correspond to one subscriber number, a plurality of card slots are required to be arranged in the multi-card multi-standby mobile terminal to place different SIM cards respectively. For example, for a dual-card dual-standby mobile terminal, two card slots are required to be arranged to respectively place two SIM cards.
In the embodiment of the invention, two embedded SIM cards or even more embedded SIM cards can be accessed simultaneously by using one embedded SIM card, so that the simultaneous standby of a plurality of numbers can be realized by only arranging one card slot in the mobile terminal, thereby reducing the space occupied by a plurality of card slots.
