Technical Field

Background
NFC (Near Field Communication) service is one of main services implemented based on UICC (Universal Integrated Circuit Card), and is a service for exchanging data in a specific range based on a contactless radio frequency technology and combined with a short-range wireless Communication technology. 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 not only applied to the telecommunication industry, but also applied to the industries such as finance, livelihood and the like. In many typical scenarios, one UICC card may carry multiple 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.
Considering that NFC is a service closely associated with a terminal and a UICC, the terminal assumes the basic communication function of NFC, and the UICC bears an NFC application and its security capability, so the NFC connection of the terminal has a direct relationship with the NFC application associated with the UICC. The state of the terminal NFC connection directly affects the feasibility of the function execution of the NFC application hosted by the UICC. If the terminal NFC connection is completed, the terminal can initiate a new NFC connection, and the function of the NFC application is normal; if the NFC application is abnormally suspended in the execution process, it means that the NFC connection of the terminal is problematic, and the function of the NFC application may be affected and needs to be focused; if the NFC connection of the terminal is interrupted due to being closed by the user, the function of the NFC application is temporarily infeasible, and the subsequent service cannot be executed. Therefore, it is necessary for the NFC application to know the NFC shutdown condition of the terminal in time, so as to clarify the influence of the NFC application on the terminal and adjust the related behavior.

Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, specific embodiments of the present disclosure are described below in detail with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
The USIM card (Universal Subscriber Identity Module) is a continuation and progress of the SIM card used in the UMTS (Universal Mobile Telecommunications System) network, and is used to store user Identity information and personal data, ensure the security of accessing Mobile network services, and perform user identification and user authorization when a user accesses the Mobile network services by using necessary functions and data, so as to meet the requirement that 3G and above networks can represent 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 resident on the 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 NFC besides the USIM card, so that the separation of the bearing platform and the application is really realized.
There is a developing process for the relationship between UICC and terminal, in the initial positioning, UICC is in a completely passive status, 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 and 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 and dominated status of receiving command, executing command and sending back response from terminal, 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 (SIM Tool, subscriber identity module Application development Tool)/USAT (USIM Application Toolkit) protocol layer is introduced into a protocol stack of a Cu interface (i.e., an interface between a terminal and a UICC), where the STK/USAT protocol layer provides a service mechanism based on a service provided by a transport layer, allows a UICC Application 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 way for a telecommunication smart card to implement a service through the terminal.
In the NFC communication process, both communication parties participate in data transmission, the party initiating communication first is called an initiator, and the party responding is called a target. In a common mode, an initiator supplies power to generate a Radio Frequency (RF) field, starts communication at a selected transmission rate, and a target device responds with load modulation data at the same rate to realize data transmission between the initiator and the target. Before the NFC communication is established, the initiator device searches for and finds the target device through the NFC device and obtains the state of the target device, and meanwhile, connects to the target device according to the instruction set by the initiator device.
As a typical service of the UICC, the NFC service generally needs to be implemented by means of terminal capabilities and combining with each other, and the requirements of the terminal and the UICC for coordination and intercommunication in the NFC service are also increasing, so the requirement of the UICC for linkage of the terminal increases, but a feasible implementation scheme has obvious disadvantages, for example, the NFC application needs to know the NFC shutdown condition of the terminal in time so as to clarify its influence on itself and adjust related behaviors, however, according to the current scheme, the requirement of the NFC application cannot be met. In order to solve the problem, the embodiments of the present disclosure adopt the following technical solutions.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order; also, the embodiments and features of the embodiments in the present disclosure may be arbitrarily combined with each other without conflict.
Fig. 1 is a flowchart illustrating a method for managing NFC connection closure by a UICC according to an embodiment of the present disclosure. As shown in fig. 1, the management method is applied to a terminal, and includes the following steps S101 to S103.
S101, establishing NFC connection with the current NFC equipment and transmitting data; the current NFC equipment refers to other NFC equipment capable of establishing NFC connection with the terminal;
s102, continuously monitoring whether the NFC connection is closed or not, once the NFC connection is closed, generating an NFC connection closing command based on the reason of the closing of the NFC connection of the terminal, sending the NFC connection closing command to the UICC, enabling the UICC to receive and analyze the NFC connection closing command, obtaining the reason of the closing of the NFC connection of the terminal, generating a response message containing a corresponding retry connection requirement based on the reason, and returning the response message to the terminal;
and S103, receiving and analyzing the response message, acquiring a retry connection requirement corresponding to the reason for closing the NFC connection of the terminal, and executing corresponding operation according to the requirement.
In this embodiment, after the terminal establishes NFC connection with other NFC devices and transmits data, once an NFC connection close action occurs, an NFC connection close command is generated based on the reason of this NFC connection close and is sent to the UICC, so that the NFC application borne by the UICC can timely learn the action of closing the NFC of the terminal and the close reason, and return a corresponding retry connection requirement to the terminal based on the reason, and the terminal executes a corresponding operation according to the requirement, which not only meets the requirement of acquiring the NFC connection close condition by the NFC application, but also realizes the relevant management requirement of the UICC, and improves service experience.
The technical scheme provided by the present disclosure is implemented based on the existing STK/USAT mechanism, and on the premise of complying with the basic mechanism of interaction between the terminal and the UICC, in order to meet the requirement of acquiring the NFC connection closing condition for the NFC application, the present embodiment extends an "NFC connection closing command" sent to the UICC by the newly added terminal, so as to synchronize the NFC connection closing behavior of the terminal to the UICC, where the command indicates the basic condition of the NFC connection and also provides the relevant specific details of closing the NFC connection. The extended add-new command is not named as a contact Connection Close, but may be named otherwise.
The contact Connection Close command structure may be as shown in table 1 below.
TABLE 1
Figure BDA0003126795360000071
In table 1, 1) "transaction identifier" indicates an NFC tag (for identifying a corresponding NFC device) of an NFC device connected this time, and is specifically defined as shown in table 1 above;
2) the 'NFC connection close reason code' is an extended data object, is optional, indicates the reason for closing the current NFC connection, and is divided into normal close after connection is completed, abnormal connection interruption due to a fault, and connection close due to the user disabling the NFC function, and the coding meaning is as shown in table 1 above.
In a specific embodiment, if the reason for closing the NFC connection of the terminal this time is that the terminal is normally closed after the NFC connection is completed, after receiving and analyzing the response message, the obtained retry connection requirement corresponding to closing the NFC connection of the terminal this time is that the connection does not need to be retried, and the NFC connection with the current NFC device is no longer established;
if the reason for closing the current NFC connection of the terminal is connection closing caused by the fact that the NFC function is forbidden by the user, after the response message is received and analyzed, the obtained retry connection requirement corresponding to the closing of the current NFC connection of the terminal is that connection retry is not needed, and the NFC connection is not established with the current NFC equipment any more;
and if the reason for closing the current NFC connection of the terminal is abnormal interruption of the NFC connection caused by a fault, receiving and analyzing the response message, and then obtaining a retry connection requirement corresponding to closing the current NFC connection of the terminal, wherein the retry connection requirement is the connection needing to be retried or the connection needing not to be retried, and retrying the connection with the current NFC equipment when the connection needing to be retried, and not establishing the NFC connection with the current NFC equipment when the connection needing not to be retried. In case of abnormal interruption of NFC connection, whether the terminal needs to retry the connection may be determined by the UICC according to the current requirements of the user or according to a preset rule.
In this embodiment, the reason for closing the NFC connection of the terminal is divided into three types, which are normal closing after the connection is completed, abnormal connection interruption due to a failure, and connection closing caused by disabling the NFC function by the user, and the three types are sent to the UICC through an NFC connection close command, and the UICC determines whether the terminal needs to retry connection based on the actual connection close reason and feeds back the connection to the terminal through a response message, and then the terminal executes a corresponding operation based on the response message, that is, whether the terminal retries connection with the current NFC device.
In addition, the "NFC connection close command" may include, in addition to the reason for closing the current NFC connection of the terminal, an NFC tag of the current NFC device (i.e., "transaction identifier" in table 1), so as to identify the NFC device connected to the terminal this time.
In a specific embodiment, if the reason for closing the NFC connection of the terminal this time is abnormal interruption of the NFC connection caused by a fault, and the obtained retry connection request corresponding to closing the NFC connection of the terminal this time is that connection retry is required, the retry connection request corresponding to the response message further includes connection retry duration.
Correspondingly, in step S103, a retry connection requirement corresponding to the reason for closing the NFC connection of the terminal this time is obtained, and a corresponding operation is executed according to the requirement, specifically:
and acquiring the requirement of connection retry needing and the connection retry duration, and retrying to establish the NFC connection with the current NFC equipment after the connection retry duration.
In this embodiment, when the reason for the closing of the NFC connection of the terminal this time is that the NFC connection is abnormally interrupted due to a fault, if the request for obtaining the connection retry required and the connection retry duration are acquired from the response message returned by the UICC, the NFC connection is retried to be established with the current NFC device based on the NFC tag of the current NFC device after the connection retry duration elapses.
In a specific embodiment, if the reason for closing the NFC connection of the terminal this time is that the connection is closed due to the user disabling the NFC function, the response message further includes a prompt text and a text display duration. The specific content of the prompt text may be preset according to a user requirement, for example, the user may be prompted to disable the NFC function to affect the NFC service, or be prompted to re-enable the NFC function, or only be prompted to the user that the current NFC connection is closed and the reason for closing.
Accordingly, after step S103, the following step S104 is also included:
and S104, acquiring a prompt text and text display duration, and displaying the text after the text display duration.
Of course, in addition to connection shutdown caused by disabling of the NFC function by the user, for both normal shutdown after the NFC connection is completed and abnormal interruption of the NFC connection caused by a fault, the corresponding response message may also include related text content and text display duration, and the specific text content and text display duration may be set and adjusted by those skilled in the art according to actual needs.
The method for managing the NFC connection closing of the UICC provided by the embodiment of the disclosure is directed at the requirement that the NFC application of the UICC timely acquires the NFC closing condition of the terminal, and a specific implementation scheme is provided by utilizing the existing STK/USAT basic framework and mechanism through the extension of the basic mechanism of the machine-card interface. The scheme can practically solve the problems and the defects of the NFC application between the machine-card interaction and strengthen the management capacity of the NFC application, can improve the efficiency and the user experience of the NFC service, and provides reference and implementation methods for the improvement of the NFC service.
Fig. 2 is a flowchart illustrating another UICC management method for NFC connection closure according to an embodiment of the present disclosure. As shown in fig. 2, the management method is applied to the UICC, and includes the following steps S201 to S203.
S201, receiving an NFC connection closing command sent by a terminal, wherein the NFC connection closing command is generated by monitoring that the NFC connection is closed in the process of continuously monitoring whether the NFC connection is closed and based on the reason of the closing of the NFC connection;
s202, analyzing the NFC connection closing command to obtain the reason for closing the NFC connection of the terminal;
and S203, generating a response message containing the corresponding connection retry requirement based on the reason for closing the current NFC connection of the terminal, and returning the response message to the terminal so that the terminal receives and analyzes the response message, obtains the connection retry requirement corresponding to the reason for closing the current NFC connection of the terminal, and executes corresponding operation according to the requirement.
In this embodiment, after the UICC receives the NFC connection close command generated by the terminal based on the reason for the current NFC connection close, the NFC application carried by the UICC can timely learn the NFC close behavior and the close reason of the terminal, and return a corresponding retry connection requirement to the terminal based on the reason, so that the terminal executes a corresponding operation according to the requirement, which meets the requirement for acquiring the NFC connection close condition by the NFC application, and also meets the requirement for UICC related management, thereby improving the service experience.
After the terminal sends a contact Connection Close command to the UICC (see the previous embodiment in detail), the NFC application hosted by the UICC can timely know the behavior of closing the NFC of the terminal and the reason for closing the NFC, generate a corresponding response message based on the reason, and then return the response message to the terminal. The command structure of the response message may be as shown in table 2 below.
TABLE 2
Figure BDA0003126795360000101
In table 2, 1) "text" is an optional data object, which represents the text content to be displayed, such as prompting the influence on the NFC service in the case that the user disables the NFC function;
2) the 'duration 1' is a data object which is required to be selected by a condition, the data object must exist when the 'text' exists, the text is displayed after a certain duration, for example, the UICC can select to display the text after a certain duration according to the requirement of using the NFC service so as to prompt a user to restart the NFC function, and the like, the duration interval of the 'duration 1' is 00, and the text is displayed immediately;
3) duration 2 is an optional data object and indicates a time interval in which the UICC requires the terminal to retry establishing connection with the current NFC device, a duration interval of duration 2 of 00 indicates immediate retry of connection, and a duration interval of FF indicates no retry of connection.
In one embodiment, step S203 includes:
if the reason for closing the NFC connection of the terminal is that the terminal is normally closed after the NFC connection is completed, generating a response message which does not need to retry the connection, and returning the response message to the terminal so that the terminal does not establish the NFC connection with the current NFC equipment after receiving and analyzing the response message;
if the reason for closing the NFC connection of the terminal is that the connection is closed because the NFC function is forbidden by the user, generating a response message which does not need to retry the connection, and returning the response message to the terminal, so that the terminal does not establish the NFC connection with the current NFC equipment after receiving and analyzing the response message;
if the reason for closing the current NFC connection of the terminal is abnormal interruption of the NFC connection caused by a fault, generating a response message which requires connection retry or does not require connection retry, and returning the response message to the terminal, so that after the terminal receives and analyzes the response message, if the response message requires connection retry, the terminal retries to establish the NFC connection with the current NFC equipment, and if the response message requires connection retry, the terminal does not establish the NFC connection with the current NFC equipment. In case of abnormal interruption of NFC connection, the UICC may determine whether the terminal needs to retry connection according to the current requirements of the user or according to a preset rule.
In a specific embodiment, if the reason for closing the NFC connection of the terminal this time is abnormal interruption of the NFC connection caused by a failure, and the UICC generates a response message requiring connection retry based on the reason, the connection retry requirement corresponding to the response message further includes connection retry duration, so that after the terminal receives and analyzes the response message, the requirement requiring connection retry and the connection retry duration are obtained, and after the connection retry duration, the terminal retries to establish the NFC connection with the current NFC device.
In a specific embodiment, if the reason for closing the NFC connection of the terminal this time is that the connection is closed due to the user disabling the NFC function, the generated response message further includes a prompt text and text display duration, so that after the terminal receives and analyzes the response message, the prompt text and the text display duration are obtained, and after the text display duration passes, the text is displayed. The specific content of the prompt text may be preset according to a user requirement, for example, the user may be prompted to disable the NFC function to affect the NFC service, or be prompted to re-enable the NFC function, or only be prompted to the user that the current NFC connection is closed and the reason for closing.
As can be seen from the foregoing description, for the reason that the NFC connection of the terminal is closed, in the case of normal closing after the NFC connection is completed, the response message generated by the UICC may or may not include the data object of "text" and "duration 1" in table 2, but must include the data object of "duration 2", and the value of "duration 2" is FF (i.e., the connection does not need to be retried); in the case that the connection is closed due to the user disabling the NFC function, the response message generated by the UICC may or may not include the data objects of "text" and "duration 1" in table 2, but must include the data object of "duration 2", and the value of "duration 2" is FF (i.e., the connection does not need to be retried); under the condition of abnormal interruption of the NFC connection caused by a fault, a response message generated by the UICC may or may not include the data object of "text" and "duration 1" in table 2, but must include the data object of "duration 2", and the value of "duration 2" may be any value, for example, if the value of "duration 2" is 00, immediately attempt to establish an NFC connection with the current NFC device, if the value of "duration 2" is n, retry to establish an NFC connection with the current NFC device after a duration n, and if the value of "duration 2" is FF, no longer establish an NFC connection with the current NFC device.
Then the UICC sends the generated response message to the terminal, so that the terminal obtains a retry connection requirement corresponding to the reason for closing the NFC connection of the terminal at the time and a possibly existing requirement on displaying a text after receiving the response message, if the response message contains the requirement on displaying the text, namely a data object containing the text and the duration 1, the terminal immediately displays the text according to the requirement or displays the text in a delayed manner after a certain duration; for the requirement of retrying connection aspect contained in the response message, namely the data object containing the 'duration 2', if the 'duration 2' is not FF, the terminal immediately retryes connection according to the requirement or retryes connection after a certain duration, and if the 'duration 2' is FF, connection does not need to be retryed.
The method for managing the NFC connection closing of the UICC provided by the embodiment of the invention aims at the requirement that the NFC application of the UICC timely knows the NFC closing condition of the terminal, and provides a specific implementation scheme by utilizing the existing STK/USAT basic framework and mechanism through the extension of the basic mechanism of the machine-card interface. The scheme can practically solve the problems and the defects of the NFC application between the machine-card interaction and strengthen the management capacity of the NFC application, can improve the efficiency and the user experience of the NFC service, and provides reference and implementation methods for the improvement of the NFC service.
