Description

NFC capability synchronization method, UICC, terminal, device and medium
Technical Field

Near Field Communication (NFC) service is one of the common functions of current user mobile devices, and is a service for performing data exchange in a specific range formed by combining a Near Field Communication technology on the basis of a non-contact radio frequency technology, and the NFC service is closely associated with mobile Communication, is one of important services developed by operators, has a very common service range, and is applied to not only the telecommunication industry but also the industries such as finance, civilian life and the like. There are generally two possibilities for implementing NFC services — terminal-based implementation and UICC (Universal Integrated Circuit Card) -based implementation, mainly distinguishing whether NFC applications and security capabilities are loaded on a terminal or a UICC. The NFC service realized based on the UICC has independent hardware security guarantee, and is relatively closer to the security requirement of a typical service; the NFC service realized based on the terminal is a full-terminal scheme, the realizability is higher, and the problem of compatibility with a security module does not exist. In many typical scenarios, an NFC entity such as a terminal or a UICC card may bear a plurality of business applications such as a bank card, a bus card, an access control card, an identification card, a campus/enterprise one-card, and the like.
The schemes of different bearer entities of NFC have influence on each other, and NFC applications can only adopt one scheme, which means that another scheme is idle. It is therefore necessary for the UICC to know the NFC capability of the current terminal, i.e. the support for different solutions, as one of the bearer entities, in order to know the impact on the extent of usage of the NFC functionality of the UICC. Because the terminal is in a relatively active position in the NFC service, for a scheme implemented based on the terminal, the terminal can complete the NFC service without the UICC participating, and therefore the UICC lacks a channel to know the NFC capability of the terminal under such a condition.

Detailed Description
In order to make the technical solutions of the present disclosure better understood by those skilled in the art, the present disclosure is further described in detail below with reference to the accompanying drawings and examples.
In which 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 the disclosed 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 the NFC service, and influence and restrict each other in the aspect of the NFC service, and the terminal and the UICC have the necessity of information synchronization. However, the UICC cannot effectively obtain the NFC capability of the terminal at present due to its relatively passive location in the card relationship.
The following describes the technical solutions of the present disclosure and how to solve the above problems in detail with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 1 is a flowchart illustrating a method for synchronizing NFC capabilities according to an embodiment of the present disclosure, which is applied to a UICC, and as shown in fig. 1, the method includes:
step S101: when the UICC generates a requirement for requiring the terminal to synchronize the NFC capability of the terminal, generating a first command according to a pre-expanded active command requirement, wherein the first command comprises the requirement for providing the NFC capability information of the terminal by the terminal;
step S102: sending the first command to the terminal, so that the terminal obtains the requirement of the first command after analyzing the first command, obtains the terminal NFC capability information according to the requirement of the first command, generates a response message according to the obtained terminal NFC capability information and sends the response message to the UICC;
step S103: and receiving the response message, 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 (USIM), in an embodiment of the present disclosure, the Mobile Equipment is called a terminal, the UICC is a Universal Integrated Circuit Card (UICC), and the UICC has a USIM.
The USIM is a continuation and progress of a SIM card used in a UMTS (Universal Mobile Telecommunications System) network, and is used to store user identity information and personal data, ensure security of access to Mobile network services, and perform user identification and user authorization when a user accesses the Mobile network services by using necessary functions and data, thereby implementing a requirement that a 3G network can express and identify user applications. In contrast to SIM cards, USIM cards are no longer built on a single telecommunications application platform, but will become one of a variety of applications residing on a universal integrated circuit card UICC. The UICC is a universal intelligent card platform, provides uniform bottom layer support for upper layer application, and can reside other intelligent card applications such as bank, ticket and the like besides the USIM, thereby really realizing the separation of the bearing platform and the application.
There is a developing process for the relationship between UICC and terminal, in the initial positioning, UICC is in a completely passive state, terminal sends command to UICC, UICC executes command and returns response to terminal, terminal and UICC interact in command/response pair mode, and all are the mode of terminal initiated command UICC response, this mechanism does not allow UICC to actively send command to terminal, terminal is always dominant, UICC can only be in a controlled state of accepting command from terminal, executing command, and sending back response, thus limiting the development and use of card based application.
With the development of UICC service requirements, in order to solve such problems, an STK/USAT protocol layer is introduced into a protocol stack of a Cu interface (interface between a terminal and a UICC), and the STK/USAT layer provides a service mechanism based on a service provided by a transport layer, so that a UICC application is allowed to interact and operate with a terminal supporting the service mechanism, so that the UICC can actively request the terminal to perform a certain operation, and an STK/USAT instruction set is a basis and a main mode for a telecommunication smart card to implement a service through the terminal. Various applications may also be implemented on the UICC by means of the STK/USAT protocol and provided to the user via the terminal. However, the UICC has no way to obtain the capability information of the terminal regarding NFC, and there is no corresponding command in the prior art,
in order to realize that the UICC can require the terminal to provide NFC capability information when needed, and the terminal provides the capability and current state of the terminal in the NFC after receiving the requirement, a UICC active command type facing NFC capability synchronization needs to be added to the STK/USAT mechanism, and the command is used for the UICC to require the terminal to provide the NFC capability information thereof. The new active command is not named Get Capability on NFC, and the structure of the command is shown in table 1 below:
