The implementation of NFC services is generally two possibilities-terminal-based implementation and UICC (Universal Integrated Circuit Card ) -based implementation, the main difference being whether the NFC application and security capabilities are loaded on the terminal or UICC. NFC business realized based on UICC has independent hardware security guarantee, so that the NFC business is relatively closer to the security requirement of typical business; the NFC service realized based on the terminal is an all-terminal scheme, the realizability is stronger, and the problem of compatibility with a security module does not exist. In many typical scenarios, NFC entities such as terminals or UICC cards may carry multiple business applications such as bank cards, bus cards, access cards, identification cards, campus/business cards, and the like.
The schemes of different bearer entities of NFC are mutually influential, and NFC applications can only take one scheme, while implying the idling of another scheme.

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. The UICC, due to its relatively passive position in the set-card relationship, is currently not able to effectively obtain the terminal-based NFC capability.
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 an NFC capability synchronization method provided in an embodiment of the present disclosure, which is applied to UICC, as shown in fig. 1, where the method includes:
step S101: after the UICC generates a requirement for requiring the terminal to synchronize its NFC capability, generating a first command according to the pre-extended active command requirement, wherein the first command contains a requirement for the terminal to provide its NFC capability information;
step S102: the first command is sent to the terminal, so that the terminal analyzes the first command to obtain the requirement of the first command, obtains the NFC capability information of the terminal according to the requirement of the first command, and generates a response message according to the obtained NFC capability information of the terminal and sends the response message to the UICC;
step S103: and receiving the response message, and analyzing and processing the response message to acquire the NFC capability information of the terminal.
The User Equipment (UE) includes a Mobile Equipment (ME) and a subscriber identity module, which in the embodiment of the present disclosure is called a terminal, and the subscriber identity module is a universal integrated circuit card (Universal Integrated Circuit Card UICC) with a universal subscriber identity module (Universal Subscriber Identity Module USIM).
The universal subscriber identity module 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, guaranteeing the security of access to mobile network services, and performing subscriber identification and subscriber authorization when a user accesses mobile network services by utilizing necessary functions and data, so as to realize the requirements that a 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.

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 acquire capability information about NFC of the terminal, in the prior art there is no corresponding command,
in order to realize that the UICC can require the terminal to provide NFC capability information when needed, the terminal provides the capability and the current state of the terminal in NFC after receiving the request, and the UICC active command type facing to the synchronization of the NFC capability needs to be added in the STK/USAT mechanism, and the command function is that the UICC requires the terminal to provide the NFC capability information thereof.
