Contactless service

Description

Mobile terminal system with non-contact module {MOBILE TERMINAL SYSTEM HAVING CONTACTLESS MODULE}

The present invention relates to a contactless service system, and more particularly, to a mobile terminal for performing a contactless service.

A portable terminal is a portable device that is portable and has one or more functions such as voice and video calling, information input and output, and data storage.

As the functions of mobile terminals are diversified, not only multimedia functions such as photographing and video recording, music and video file playback, but also financial functions such as game function, broadcast reception function, and contactless payment service are provided. to provide.

The contactless payment service may include transportation pass services, banking services, electronic wallets, payment or conditional access services, and the portable terminal may be configured as such. It includes a contactless module (ContactLess Module) that performs the same contactless payment service.

The contactless transaction performed through the mobile terminal may be independently performed regardless of the state of the terminal. Contactless transactions can even be made with the terminal powered off or without battery power (the energy is induced by the magnetic field). However, some contactless payment services are performed when the mobile terminal is activated (eg, when the user needs to interact with the display and keyboard). In this case, a security problem may occur. Thus, service providers hope that no transaction is initiated when the terminal cannot perform a complete transaction.

The present invention is to provide a contactless service system for performing a connectionless transaction using a contactless module that knows the state information of the terminal.

Further, the present invention is to provide a portable terminal having a contactless module that knows the state information of the terminal.

The contactless module and its implementation according to the present invention brought the improvement of security and performance of the contactless service as follows, and increased user convenience.

When it is predicted that the contactless module cannot be performed correctly, i.e., the terminal is turned off and the contactless transaction requires interaction between the terminal and the user, the contactless service according to the present invention maintains the security of the transaction. Minimize risk exchange.

The present invention reduces the terminal unnecessary operations by greatly reducing impossible requests and reducing information exchange as necessary. The result is improved system performance to save power and resources.

The present invention makes it clear to the user (or system provider) about the contactless transaction that cannot be effectively performed at the beginning of the service, thereby preventing unsuccessful and unsuccessful attempts in advance.

In order to achieve the above object, the contactless service system according to the present invention comprises a terminal for storing its state information in the contactless module, and a server connected to the contactless module to perform a predetermined contactless transaction.

In order to achieve the above object, a portable terminal according to the present invention comprises:

And a memory card for storing state information of the terminal, and a contactless module for providing the state information to a server when a predetermined transaction is started.

An object of the present invention is to store the state information of the terminal in a contactless module (or UICC). That is, by storing the state information of the terminal in the contactless module, when the contactless transaction is started, the service provider (or reseller) determines whether the transaction can be executed until the end of the contactless service, and whether or not to start the actual transaction. To make a decision.

The state information of the terminal stored in the non-contact module is related to whether the terminal is currently powered off, or whether the terminal is in operation or ready to operate.

The following two methods can be considered as a method of obtaining the state information of the terminal.

First, how to try unresponsive communication.

Secondly, the terminal is registered in the contactless module when the terminal is powered on, and the registration of the terminal is canceled when the power is turned off.

The interface unit 170 serves as a path allowing the terminal to exchange data with an external device. For example, the interface unit 170 may be a wired or wireless connection terminal for connecting to an earphone, a port for short range communication (e.g., an IrDA port, a Bluetooth port, a wireless LAN port a wireless LAN port, etc.), or power supply terminals for supplying power to external devices.

The interface unit 170 may be a card socket for accommodating an external card such as a subscriber identification module (SIM) or a user identity module (UIM) or a memory card for storing information. Since the detailed description of the interface unit 170 is already described above, it will be omitted.

The power supply unit 190 for supplying power to the terminal is mounted on the second rear case 100B-2.

The power supply unit 190 may be detachably coupled to a rechargeable battery, for example, for charging.

3 is a rear perspective view of a portable terminal according to an embodiment of the present invention.

Referring to FIG. 3, a second camera module 121-2 may be additionally mounted on the rear surface of the second rear case 100B-2 of the second body 100B. The second camera module 121-2 may have a photographing direction substantially opposite to that of the first camera module 121-1 (see FIG. 1), and may have different pixels from the first camera module.

For example, the first camera module 121-1 has a low pixel so that the user's face is photographed and transmitted to the counterpart in case of a video call, and the second camera module 121-2 is a general subject. It is preferable to have a high pixel because it is not often photographed and transmitted immediately.

The flash 121-3 and the mirror 121-4 may be further disposed adjacent to the second camera module 121-2. When the flash 121-3 photographs a subject with the second camera module 121-2, light is emitted toward the subject.

4 illustrates the interface unit 170 of FIG. 1 in more detail, and is a block diagram illustrating a physical interface of the contactless module / UICC. 5 is a block diagram in which a power supply of the UICC is connected to a non-contact module.

The principle of contactlessness is to include a contactless module (aka ContactLess Function for contactless function) in a mobile terminal. The contactless module is optionally connected to a universal IC card (UICC) and a terminal baseband as shown in FIG. 4. In addition, the same method as the method of connecting with the UICC may be connected to some secure elements.

As shown in FIG. 5, the non-contact module can obtain power from a terminal battery or an electromagnetic field. Use the electromagnetic field when the terminal battery is too low to supply power. The current generated by the electromagnetic field in the contactless module turns on the UICC (or a security member such as an SD card). Thus, in the case of a battery off mode, the contactless service can be executed as long as it is not associated with a terminal (interaction with a user). 6 is a UICC power management block diagram for managing the power of the UICC by the battery of the terminal, Figure 7 is a UICC power management block diagram managed by the contactless module.

Among contactless services, some contactless services, such as transport passes, IDs, and the storage of tags and information in secure elements, do not require any user interaction, so the battery is turned off. You can also operate in) mode.

On the other hand, the following contactless services require mandatory interaction with the user.

-Financial transactions (bank transfers, etc.)

- Credit card

-Electronic wallet (depending on implementation), etc.

In the case of the contactless services that require mandatory interaction with the user, for security reasons there is an additional value that prevents the transaction from starting. The contactless services are not executed until the end of the interaction with the user via the telephone, i.e., until the supplementary value becomes valid.

One of the problems pointed out in such a contactless service is that the contactless module and the IC card (UICC) do not have the status information of the terminal (when the power is turned on by the contactless module).

The non-contact module and the IC card (UICC) according to the present invention store state information of the terminal, that is, whether the terminal is in operation or ready to operate, or whether the terminal is powered off.

First, there is no response communication as two ways of obtaining the information (hereinafter referred to as false communication (fake communication ) .

8 is a flow diagram of a method of attempting an unresponsive communication.

As shown in FIG. 8, the non-contact module performs the false communication with the terminal at regular time intervals (periodically). (There is a comparable system so that the terminal can detect the UICC by pressing STATUS every 30 seconds in idle mode). If no response is given before timeout, the terminal is considered out of order. The proactivity of this mechanism is based on the management of information polling (timer values).

In further development, it may be considered to store the state of the terminal (more specifically, the profile of the terminal) in a dedicated memory unit of the terminal.

9 is a flowchart illustrating a method of storing a profile of a terminal in a dedicated memory unit of the terminal. As shown in Fig. 9, instead of attempting communication, it may be simpler to check the terminal state information in the dedicated memory unit for each predetermined timeslot. The proactivity of the present invention is based on the management of the information polling (timer value).

Semi-permanent and accessible information storage is not entirely applicable to contactless interfaces.

Another alternative to the first method above is to check the state of the terminal only when a contactless transaction is attempted. The advantage of reducing power consumption is that the information is checked only once, rather than periodically, while there is a slight delay in obtaining the information.

As a second method of obtaining the status information of the terminal, there is a method of registering the terminal to the contactless module when the terminal is powered on, and canceling the registration of the terminal when the power is turned off. The second method is preferably used in a situation where the battery power of the terminal is sufficient or the power supply to the terminal is smooth.

The active state of the terminal that may affect the contactless service will be described in more detail as follows.

1.Idle mode with display off (sleep mode)

2. Active mode with display on

3. Communication mode (video or voice communication)

4. Music play / broadcast mode

5. Web browsing mode of operation (eg internet access)

The state information of the present invention may be managed in the same manner as managing the terminal profile in the UICC (see ETSI TS 102 2223, & 5). The information is a set of bytes containing tags for numerous service support. The effect on the software of the terminal is to design a system that updates the database of such information in some new state (new communication, etc.).

The present invention presents the possibility of extending and standardizing the terminal profile toolkit command for use by other modules as well as UICC.

In addition, the present invention has proposed the possibility of designing a contactless module-related command that is generally applied to the device to obtain information from the terminal.

The present invention can confirm whether the terminal power is turned off for whatever reason (either due to battery discharge or power off of the user). The inactive state of the terminal that may affect the contactless service will be described in detail as follows.

1. The power of the terminal is off (battery is sufficient)

2. The terminal is powered off due to battery discharge

The basic method of causing a difference between the power off states of 1 and 2 is to use the information from the power management system of the contactless module and the basic proposal of the present invention in different ways. If battery power remains and the terminal activation cannot be detected, it corresponds to the power off state of 1. In addition, if power is not detected, the power is turned off.

Hereinafter, two situations according to the present invention will be described.

Case 1: X wants to pay by bank card with his terminal abroad, but his terminal has a dead battery. Contactless transactions cannot be made in any way. In this case, the contactless transaction according to the present invention will fail before the sensitive information of the terminal is transmitted to the server side (for example, Bank Y).

Case 2: Bank Y would like to have a minimum exchange of information if the contactless service cannot be performed correctly. The present invention performs a contactless transaction that satisfies this demand of Bank Y. When a contactless transaction is attempted, the terminal state is returned to the state at which the terminal was purchased, and a policy is defined as to whether or not to continue the transaction.

Although the present invention has been described with reference to the embodiment (s) shown in the drawings, this is merely exemplary, and various modifications can be made therefrom by those skilled in the art, and the embodiments described above It will be appreciated that all or part of the (s) may be optionally combined. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.

The contactless module and its implementation according to the present invention brought the improvement of security and performance of the contactless service as follows, and increased user convenience.

When it is predicted that the contactless module cannot be performed correctly, i.e., the terminal is turned off and the contactless transaction requires interaction between the terminal and the user, the contactless service according to the present invention maintains the security of the transaction. Minimize risk exchange.

The present invention reduces the terminal unnecessary operations by greatly reducing impossible requests and reducing information exchange as necessary. The result is improved system performance to save power and resources.

The present invention makes it clear to the user (or system provider) about the contactless transaction that cannot be effectively performed at the beginning of the service, thereby preventing unsuccessful and unsuccessful attempts in advance.
