detailed description

In order to solve the problem that the prior art cannot switch between multiple profiles in the ESIM card under special circumstances, the present invention provides a method and device for switching configuration files. The present invention is further detailed in conjunction with the accompanying drawings and embodiments. Description. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

A first embodiment of the present invention provides a method for switching a configuration file. The flowchart is as shown in FIG. 1 , and specifically includes steps S101 and S102: S101. The ESIM card receives a handover instruction from a CPU through a preset interface. The ESIM card switches the currently used first configuration file to the second configuration file according to the switching instruction.

In the prior art, a user uses a smart phone with an ESIM card, and at least two different profiles (ie, configuration files) are stored in the ESIM card, such as a profile for China Mobile and another profile for China Telecom. When the network is unblocked, the local profile management program (LPA, Local Profile Assistant) in the smartphone can be used to switch between profiles. The user can intuitively experience that the current number is switched from China Mobile's number to China. The number of the telecom, when the user uses the data traffic, the connected network is switched from China Mobile's network to China Telecom's network.

In some special cases, such as when the user is in a tunnel, in a basement environment, or when the smartphone is in factory mode or recovery mode, the smartphone cannot connect to the network and thus cannot switch between profiles. At this time, in this embodiment, the user can click the setting interface of the smart phone, and the CPU calls the preset interface to send a switching instruction to the ESIM card. After receiving the switching instruction, the ESIM card does not need to be connected. Switch the currently used first profile to the second profile. When the first profile is the configuration file of China Mobile and the second profile is the configuration file of China Telecom, the ESIM card receives the switching instruction through the preset interface, and according to the switching instruction, the Chinese mobile number is switched to the Chinese telecommunication number. The default interface includes the Native interface in the RIL of the Android architecture. Since the Native interface is not in the application layer, the interface cannot be called when the interface is invoked. Further, the preset interface may be a Qualcomm Mobile Software Management Interface (QMI) of the Qualcomm platform or another interface that can implement the same function. Before sending a switching instruction to the ESIM card, the data transmission channel between the CPU and the ESIM card should be established first, for example, using a command such as OpenChannel to complete the opening of the data transmission channel.

In this embodiment, the ESIM card is a white card before the user uses it, that is, the profile of any one carrier is not stored in the ESIM card. Therefore, before use, multiple profiles need to be stored in the ESIM for the user to use and switch. When storing multiple profiles in ESIM, the smartphone manufacturer can pre-configure the profile in the mobile phone when the mobile phone is produced, but it does not meet the purpose of remote configuration profile; therefore, the LPA program is used to connect the carrier through wireless network or traffic at this stage. A profile data management server (SMDP+, Subscription Manager Data Preparation) is provided for providing a profile, and the profile provided by the SMDP+ server is encrypted and transmitted through a HyperText Transfer Protocol (HTTP), and finally downloaded to the terminal through the LPA. ESIM card. However, the above method cannot be completed without a network, and the data in the card cannot be modified at any time. Therefore, in this embodiment, the profile server is completed by the simulation server, and the process of encrypting and transmitting through the HTTP protocol is completed, so that the profile package file generated by the simulation server is a profile package file conforming to the preset format of the GSMA specification, and no network connection is required. After being transmitted to the ESIM card through the air interface of the LPA, the ESIM card parses the profile package file in the preset format after receiving the profile package file in the preset format, and stores the parsed multiple profiles.

It should be understood that the embodiment can also be used in the test of the ESIM card production process. With the solution of the embodiment, the step of connecting the network can be omitted, which saves test time and saves test cost. During the test, because the production line is at the same time, multiple terminals will be powered on at the same time. During the test, because the resources of the profile are limited, when the terminals storing the same profile are powered on at the same time, conflicts may occur, and the test cannot be completed. . Therefore, grouping operations can be performed on the production line. For example, a total of 1000 terminals need to be tested, but only 20 profiles are available. In this case, the terminals to be tested can be divided into 50 groups, and 20 terminals can be allowed together at the same time. By testing, the profile rotation between different groups can avoid the conflict caused by the first profile resource.

In this embodiment, the switching instruction is received through the preset interface, so that the ESIM card is switched from the currently used first profile to the second profile, so that switching between profiles in the ESIM card without connecting to the Internet is needed, and the existing solution is solved. The technology can not switch between multiple profiles in the ESIM card when the technology is off the network.

A second embodiment of the present invention provides a configuration file switching device. The schematic structure of the device is as shown in FIG. 2, and specifically includes a receiving module 201 and a switching module 202 coupled to each other. The receiving module 201 is configured to receive a switching instruction from the CPU by using a preset interface, and the switching module 202 is configured to switch the currently used first profile to the second profile according to the switching instruction.

In the prior art, a user uses a smart phone with an ESIM card, and at least two different profiles are stored in the ESIM card, such as a profile for China Unicom and a profile for China Mobile, where the user is unblocked in the network. In the case of LPA, the user can switch between profiles. The user can intuitively experience that the current number is switched from China Unicom's number to China Mobile's number. When the user uses data traffic, the connected network is connected by China Unicom's network. Switch to China Mobile's network.

In some special cases, such as when the user is in a tunnel, in a basement environment, or when the smartphone is in factory mode or recovery mode, the smartphone cannot connect to the network, and thus the profile cannot be switched. At this time, in this embodiment, the user can click the setting interface of the smart phone, and the CPU calls the preset interface to send a switching instruction to the ESIM card. After receiving the switching instruction, the ESIM card does not need to be connected. Switch the currently used first profile to the second profile. When the first profile is the configuration file of China Unicom and the second profile is the configuration file of China Mobile, the ESIM card receives the switching instruction through the preset interface, and according to the switching instruction, the Chinese Unicom number is switched to the Chinese mobile number. The preset interface includes a Native interface in the AndroidRIL layer. Since the Native interface is not in the application layer, the interface cannot be called when the interface is invoked. Further, the preset interface may be a QMI interface of the Qualcomm platform or another interface that can implement the same function.

Before sending the switching instruction to the ESIM card, the data transmission channel between the CPU and the ESIM card is first established through the channel establishment module, for example, using a command such as OpenChannel to complete the opening of the data transmission channel.

In this embodiment, the ESIM card is a white card before the user uses it, that is, the profile of any one carrier is not stored in the ESIM card. Therefore, before using, multiple profiles need to be stored in the ESIM for the user to use and switch. When storing multiple profiles in ESIM, the smartphone manufacturer can pre-configure the profile in the mobile phone when the mobile phone is produced, but it does not meet the purpose of remote configuration profile; therefore, the LPA program is used to connect the carrier through wireless network or traffic at this stage. The provided profile is used to provide the SMDP+ server, and the profile provided by the SMDP+ server is encrypted and transmitted through the HTTP protocol, and finally downloaded to the ESIM card of the terminal through the LPA. However, the above method cannot be completed without a network, and the data in the card cannot be modified at any time. Therefore, in this embodiment, the profile server is completed by the simulation server, and the process of encrypting and transmitting through the HTTP protocol is completed, so that the profile package file generated by the simulation server is a profile package file conforming to the preset format of the GSMA specification, and no network connection is required. The air interface of the LPA is transmitted to the storage module. After receiving the profile package file in the preset format, the storage module parses the profile package file in the preset format and stores the parsed multiple profiles.

A third embodiment of the present invention provides a mobile terminal using a switching device of a configuration file in the second embodiment of the present invention.

When the mobile terminal is shipped from the factory, the ESIM card embedded in the mobile terminal does not have any profile file of the operator. When the user purchases and needs to use the mobile terminal, the profile needs to be written first. In the case that the user is connected to the wireless network, the mobile terminal downloads the corresponding profile (equivalent to the first profile in the first embodiment of the present invention) on the SMDP+ server of China Mobile through the LPA program and stores it in the ESIM card. You can use China Mobile's number to make calls, send and receive text messages, etc.; if the user is not connected to the network, the analog server generates a profile package file of China Telecom's profile that conforms to the GSMA standard preset format. The ESIM card obtains the LPA through the air interface of the LPA. The file is packaged, and the parsed profile (corresponding to the second profile in the first embodiment of the present invention) is stored.

The user currently uses the number of China Mobile. When the user needs the number of China Telecom in the basement to reply to the SMS, it finds that the current network cannot be connected. At this time, the user calls the QMI interface to the ESIM card by clicking the setting interface of the mobile terminal. After the handover command is received, the ESIM card switches the profile of the currently used China Mobile to the profile of China Telecom, and then responds to the SMS after the handover, after the handover command is not required.
