Detailed Description
In order that those skilled in the art will better understand the technical solutions of the present disclosure, the present disclosure will be described in further detail with reference to the accompanying drawings and examples.
Wherein the terminology used in the embodiments of the disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used in this disclosure of embodiments and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
The terminal and the UICC are used as different bearing entities of NFC service, and influence and restrict each other in the aspect of NFC service, and have the necessity of information synchronization. For dynamic changes of terminal NFC applications, UICCs need to synchronize their changes in real time in a viable way. The UICC cannot effectively obtain the change condition of the terminal NFC application deployment at present due to the relatively passive position of the UICC in the card relationship.
The following describes the technical solutions of the present disclosure and how the technical solutions of the present disclosure solve the above-mentioned problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
Fig. 1 is a flowchart of a method for dynamically updating NFC capability according to a first embodiment of the present disclosure, which is applied to a terminal, as shown in fig. 1, and the method includes:
step S101: acquiring a terminal NFC application change condition after the terminal NFC application based on the terminal realizing NFC service is changed;
step S102: generating a first command according to the acquired terminal NFC application change condition, wherein the first command carries terminal NFC application change information;
step S103: and sending the first command to the UICC so that the UICC receives the first command and analyzes the first command to acquire terminal NFC application change information.
The User Equipment (UE) includes a Mobile Equipment (ME) and a UICC card, and in the embodiment of the present disclosure, the Mobile Equipment is called a terminal, and the UICC has a universal subscriber identity module (Universal Subscriber Identity Module, USIM) thereon.
The USIM is a continuation and progress of a SIM card used in a UMTS (Universal Mobile Telecommunications System ) network, and is used for storing user identity information and personal data, ensuring the security of accessing mobile network services, and performing user identification and user authorization when a user accesses the mobile network services by utilizing necessary functions and data, so as to realize the requirements that the 3G network can express and identify user applications. In contrast to a SIM card, a USIM card is no longer built on a single telecommunications application platform, but will become one of many applications residing on a universal integrated circuit card UICC. The UICC is a universal smart card platform, provides uniform bottom support for upper-layer applications, and besides the USIM, other smart card applications such as banks, ticketing and the like can also reside on the UICC, so that the separation of the bearing platform and the applications is truly realized.
In the initial positioning, the UICC is in a completely passive state, the terminal sends a command to the UICC, the UICC returns a response to the terminal after executing the command, the terminal and the UICC interact in a command/response mode, and the terminal initiates the command UICC response mode, the mechanism does not allow the UICC to actively send the command to the terminal, the terminal is always dominant, and the UICC can only be in a state that the control of receiving the command from the terminal, executing the command and returning the response is dominant, so that the development and the use of card-based application are limited.
With the development of UICC service requirements, in order to solve such problems, a STK/USAT protocol layer is introduced in a protocol stack of a Cu interface (interface of a terminal and a UICC), the STK/USAT layer provides a service mechanism on the basis of a service provided by a transport layer, and allows UICC applications to interact and operate with a terminal supporting the mechanism, so that the UICC can actively request the terminal to perform a certain operation, and an STK/USAT instruction set is a basic and main mode for a telecom smart card to realize services through the terminal. Various applications can also be implemented on the UICC by means of the STK/USAT protocol and provided to the user through the terminal. However, in the prior art, the UICC cannot obtain the change information of the terminal NFC application based on the terminal implementing the NFC service, and in the prior art, no corresponding command is available yet.
In order to realize dynamic update of the terminal NFC condition by the UICC, that is, when the application condition of the terminal based on the terminal implementing NFC service changes in the terminal, the relevant condition may be obtained in real time, and the terminal may obtain the terminal NFC application change condition, specifically may obtain the terminal NFC application change condition through the NFC function, that is, after the application transmission change by the NFC function authorization or authorization inquiry using NFC provides the terminal with the application change condition or the corresponding NFC function permission change condition. Through newly adding a command in a terminal and UICC interaction mechanism in advance, the command function is that the terminal transmits dynamic change of an application based on the terminal to the UICC, the terminal generates a first command according to the command requirement and the acquired terminal NFC application change condition, the command comprises a specific command symbol, the terminal NFC application change condition is characterized, then the first command is sent to the UICC, after the UICC receives the first command, the first command is analyzed, the terminal NFC application change condition is acquired, then the influence of the current terminal NFC application change on the NFC service of the UICC is determined, and the service is correspondingly updated. For example, when an application implementing NFC service based on a terminal is no longer used, it may be correspondingly required to use UICC based NFC service, for which UICC needs to make corresponding preparation; or, a certain service based on the UICC for realizing the NFC has been used until now, when the terminal downloads the corresponding application, the terminal changes to realize the service through the NFC function of the terminal, and the UICC needs to be known so as to be convenient for management, so as to enhance the efficiency and the effect of NFC service management.
Further, the terminal NFC application change status includes any one of the following cases:
the terminal installs a new NFC application, and the new NFC application obtains NFC authorization or authorization inquiry;
the terminal uninstalls and deletes the original NFC application;

Downloading and deleting refer to downloading a new application using the terminal NFC function and deleting an original application using the terminal NFC function, and application NFC authorization change refers to changing the NFC authorization state between unauthorized, authorized and authorized interrogation states under the condition that the application deployment state is not changed. In another implementation manner of the disclosed example, when there are multiple application changes, the terminal NFC application change status may also be that multiple situations occur in the above three situations at the same time.

the generating the first command according to the acquired terminal NFC application change status includes:
determining the content of a corresponding data object in the proactive command;

for the condition that the terminal uninstalls and deletes the original NFC application, the terminal generates registered application data and a data object of an application NFC change type, wherein the value of the application NFC change type is 01;
