Description

Method and system for selecting contactless communication technology based on mobile terminal type

Technical field

The present invention relates to the field of mobile payment technologies, and in particular, to a method and system for selecting a non-contact communication technology based on a mobile terminal type. Background technique

With the advancement of technology, the functions of smart mobile terminals such as mobile phones are not limited to simple basic communication functions such as making calls and texting. It has become a portable entertainment device, and it can be used in the fields of consumption, transportation, etc. The payment is convenient and fast, and the mobile-based non-contact communication technology business (such as mobile payment service) has entered people's lives. The mobile payment service has gradually become a hot issue for mobile operators, mobile phone manufacturers, and SIM card manufacturers. The mobile payment solutions in the market have sprung up. There are two mainstream non-communication technology solutions: one is the SIMpass technology solution and the other is the SWP technology solution. To this end, related smart cards supporting SIMpass technology and smart cards supporting SW technology have emerged.

The SIMpass technology solution requires the smart card to connect to the antenna or integrate the antenna into the smart card. The smart card communicates directly with the external terminal device through the antenna. The smart card supporting SIMpass technology is also called dual-interface SIM card. It supports both contact and non-contact modes of operation. The contact interface implements the SIM function, and the contactless interface implements the contactless communication function. With SIMpass technology, a variety of mobile-based on-site non-contact communication services can be carried out with the support of wireless communication networks and corresponding terminal service platform. For example, the typical mobile payment service application scenario is Beijing-based “Tongtong Bus. Users only need to hold a SIMcard-enabled smart card to complete the payment safely and conveniently in front of the bus P0S machine. Smart cards that support SIMpass technology are limited. It is used on the corresponding mobile phone, that is, the smart card supporting SIMpass technology can only work normally on ordinary mobile phones (non-SWP mobile phones), and cannot work normally on SWP mobile phones. The reason is that mobile phones supporting SWP have the function of communicating with external terminal devices. The smart card supporting the SIMpass technology also has the function of communicating with the external terminal device, which causes the communication between the SWP mobile phone with the smart card equipped with the SIMpass technology and the external terminal device to be disordered and unable to communicate normally.

SP technology solution requires smart card to support SW protocol, mobile phone through NFC chip and external terminal The device communicates, and then the mobile phone converts the communication data into a packet conforming to the SWP protocol format, and then communicates with the smart card. The NFC chip of the mobile phone is connected to the C6 contact of the SIM card to implement data communication. SWP technology is a technology that realizes full-duplex communication on a single line. The two sides of the communication superimpose the voltage signal and the current signal to realize full-duplex communication on a single line. The smart card supporting SWP technology can only be used on the corresponding mobile phone, that is, the smart card supporting SWP technology can only work normally on the SWP mobile phone, and cannot work normally on the ordinary mobile phone. The reason is that the mobile phone supporting the SWP has an NFC chip, can communicate with the external terminal device, and converts the communication data into a data packet conforming to the SWP protocol format and a smart card communication supporting the SWP protocol. However, an ordinary mobile phone does not have an NFC chip and cannot communicate with an external terminal device, so that communication data cannot be obtained. At the same time, the ordinary mobile phone does not have the SW function, and cannot convert the communication data into a data packet conforming to the SWP protocol format and communicate with the smart card supporting the SWP protocol.

FIG. 3 is a flow chart showing a method for selecting a contactless communication technology based on a mobile terminal type according to an embodiment of the present invention, the method comprising the following steps:

Step S21: loading the smart card into the mobile intelligent terminal;

Step S22: Select a contactless communication technology supported by the smart card according to the type of the mobile intelligent terminal. The smart card of the specific embodiment supports the SIMpass technology and the single-line protocol SW technology. In the implementation manner, the dual-interface smart card chip can be integrated on the smart card to support the SIMpass technology, and the SWP technology is supported by integrating the SWP smart card chip on the smart card, that is, the specific The smart card chip in the embodiment refers to a smart card chip which integrates a SW chip and a SIMpass chip, and the chip needs to be capable of both SWP communication and SIMpass communication.

After the smart card is set to the mobile intelligent terminal, the contactless communication technology supported by the smart card is selected according to the type of the mobile intelligent terminal. In this embodiment, the types of the mobile intelligent terminal are divided into two categories, one is to support the single-wire protocol SWP technology. Terminal, which can be called SWP intelligent terminal; One type of terminal that does not support the single-line protocol sw technology can be a general intelligent terminal. In the specific embodiment, the manner of selecting the contactless communication technology supported by the smart card according to the type of the mobile intelligent terminal is as follows:

Determine whether the mobile intelligent terminal supports the single-line protocol SW technology, and if so, shield the smart card's S IMpa s s technology, otherwise the smart card's single-wire protocol SWP technology is shielded.

The present embodiment provides the following two modes: when the smart card is configured according to the type of the mobile intelligent terminal, or the single-line protocol SWP technology is used for shielding.

One way is the automatic masking mode: Specifically, the smart card automatically shields the smart card's S IMpa s s technology or the single-wire protocol SWP technology according to the type of the mobile intelligent terminal. In this mode, when the smart card interacts with the mobile intelligent terminal, the smart card automatically shields the non-connected communication technology that is not supported by the mobile intelligent terminal, and the specific mobile intelligent terminal receives the external terminal device (such as the subway credit card machine, the bus credit card machine, the bank) When a communication signal is not connected to a non-contact communication device such as a P0S machine or a access control card reader, the mobile intelligent terminal generates a signal to communicate with the smart card according to the contactless communication technology supported by the smart communication terminal, and the smart card shields the unsupported according to the type of the signal. Non-contact communication technology, for example, the mobile intelligent terminal communicates with the smart card through the SWP signal, and the smart card is automatically shielded to the S IMpa ss technology.

The other is the passive shielding method: specifically, the S IMpa ss technology or the single-line protocol SWP technology for shielding the smart card according to the contactless communication technology supported by the smart card preset by the user. When the user presets, the user-recognized application development tool STK menu presets the contactless communication technology supported by the smart card. In the actual application process, after selecting the contactless communication technology supported by the smart card, the smart card can communicate with the external terminal device according to the selected contactless communication technology, thereby completing the communication service, that is, step S23 shown in FIG. If the smart card adopts the S IMpa ss technology, the smart card communicates with the external terminal device directly through its external antenna or the antenna integrated into the smart card to complete the communication service; if the smart card adopts the SWP technology, the mobile intelligent terminal communicates with the external terminal device through the NFC chip. Then, the intelligent mobile terminal converts the communication data into a data packet conforming to the SWP protocol format, and then communicates with the smart card, thereby completing the communication service. The method and system for selecting a contactless communication technology based on a mobile terminal type described in this embodiment only needs to select a smart card when the smart card communicates with an external terminal device for the first time. With the contactless communication technology, when the smart card communicates with the external terminal device again, it is no longer necessary to select and directly communicate according to the contactless communication technology that has been selected. However, if the smart card is powered off, it is necessary to reselect the contactless communication technology supported by the smart card when communicating with the external terminal device after power-on again.

As shown in FIG. 4, after the smart card is powered into the RF field for the first time, it is ready to communicate with the external terminal device. When the smart card communicates with the external terminal device, the smart card chip generates an interrupt, and determines which non-contact communication technology is identified. To communicate, the shielding unit sets the contactless communication technology to be used by the smart card according to the current masking mode. If the masking mode is the active mode, the contactless communication technology to be used by the smart card is set according to the type of interrupt generated by the chip, and the smart card is not shielded. The required contactless communication technology is then continued with the subsequent communication processing according to the adopted contactless communication technology; if the masking mode is the passive mode, according to the contactless communication technology set by the user, the contactless communication technology to be used by the smart card is set, and the shielding is performed. The contactless communication technology that is not required by the smart card is removed, and then the subsequent communication processing is continued according to the adopted contactless communication technology. In addition, it should be noted that the mobile intelligent terminal in this embodiment includes but is not limited to a smart phone.

In the method and system of the present invention, the smart card supports both the S IMpa ss technology and the SWP technology. For example, for a smart phone, when the smart card is placed in the SWP mobile phone, it shields the S IMpa ss technology and only supports the SW technology. When the smart card is placed in a normal mobile phone, it shields the SW technology and only supports the S IMpa ss technology. At the same time, this shielding function has two modes: active mode and passive mode. Active mode: Smart card adaptive mobile phone type, that is, the smart card automatically shields the non-contact communication technology that the mobile phone does not support through the mobile phone type, and adopts the contactless communication technology supported by the mobile phone; passive mode: the mobile phone user sets the STK menu through the smart card according to the type of the mobile phone To support the contactless communication technology, the shielded mobile phone does not support contactless communication technology. The method and system of the present invention realize that a smart card can use a plurality of non-contact communication technologies, so that both the ordinary mobile intelligent terminal and the SWP mobile intelligent terminal can normally communicate with the external terminal device, thereby better satisfying the user's Communication needs. Obviously, those skilled in the art can make various modifications and variations to the present invention without departing from the invention. The spirit and scope of the invention. Thus, it is intended that the present invention cover the modifications and the modifications
