Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terminal described in the embodiment of the present invention needs to adjust and improve the NFC antenna matching circuit of the terminal before leaving the factory, so that the NFC antenna of the terminal can transmit and receive NFC radio-frequency signals in both the front and back directions of the NFC antenna. The terminal comprises an NFC antenna, an NFC controller, a security module and the like. The NFC-based signal processing method described in the embodiment of the present invention may be applied to, for example, an NFC combination scheme that supports an HCE scheme and an SWP scheme at the same time, an SWP scheme that supports two Subscriber Identity Modules (SIMs) at the same time, and an NFC combination scheme that supports a dual-system dual-domain NFC scheme.
Referring to fig. 1, which is a schematic flowchart of a signal processing method based on NFC according to an embodiment of the present invention, the method may be applied to a terminal with an NFC function and at least two security modules, such as a smart Phone (e.g., an Android Phone, an IOS Phone, a Windows Phone, etc.), a tablet computer, a Mobile Internet Device (MID), a wearable device, and the like. An NFC-based signal processing method as shown in fig. 1 may include the steps of:
s101, when the terminal receives an NFC radio frequency signal, judging a radio frequency field to which the NFC radio frequency signal belongs.
The NFC antenna of the terminal can receive signals of the first radio frequency field and the second radio frequency field, and of course, the terminal can also receive signals of other radio frequency fields. The first radio frequency field is a radio frequency field at one side of the rear shell of the terminal; the second radio frequency field is a radio frequency field at one side of the terminal screen.
In some possible embodiments, the terminal includes a first NFC antenna and a second NFC antenna, and an isolation layer is disposed between the first NFC antenna and the second NFC antenna, so that signals of the first radio frequency field can only be received by the first NFC antenna and signals of the second radio frequency field can only be received by the second NFC antenna by adjusting and modifying the NFC antenna of the terminal before the terminal leaves a factory. Specifically, when receiving an NFC radio-frequency signal, the terminal determines an NFC antenna to which the NFC radio-frequency signal belongs; if the first NFC antenna receives the NFC radio-frequency signal, determining the NFC radio-frequency signal as a signal of the first radio-frequency field; and if the NFC radio frequency signal is received by the second NFC antenna, determining the NFC radio frequency signal as a signal of the second radio frequency field.
In some possible embodiments, the terminal is configured to adjust and modify the NFC antenna and the antenna matching circuit of the terminal before the terminal is shipped, so that the radio frequency field on the side of the terminal screen can only be received by the NFC antenna (the second NFC antenna) of the terminal in the forward direction (e.g., the direction corresponding to the side of the terminal screen) of the NFC antenna of the terminal, and the radio frequency field on the side of the terminal rear housing can only be received by the NFC antenna (the first NFC antenna) of the terminal in the reverse direction (e.g., the direction corresponding to the side of the terminal rear housing) of the NFC antenna of the terminal. The NFC antenna matching circuit includes an antenna matching circuit 1 and an antenna matching circuit 2, and only NFC radio-frequency signals received by a second NFC antenna included in the terminal can be transmitted to the NFC controller through the antenna matching circuit 1, and only NFC radio-frequency signals received by a first NFC antenna included in the terminal can be transmitted to the NFC controller through the antenna matching circuit 2. Therefore, when the NFC controller of the terminal receives the NFC radio-frequency signal transmitted by the antenna matching circuit 1, it can be determined that the NFC radio-frequency signal is a signal of a radio-frequency field on one side of the terminal screen, that is, a second radio-frequency field; when the NFC controller of the terminal receives the NFC radio-frequency signal transmitted by the antenna matching circuit 2, it may be determined that the NFC radio-frequency signal is a signal of the first radio-frequency field, which is the radio-frequency field on one side of the rear housing of the terminal.
In some possible embodiments, when the terminal receives the NFC radio-frequency signal, first a distance value between the distance sensor and the obstruction is obtained by a distance sensor provided in the terminal, and then a radio-frequency field to which the NFC radio-frequency signal belongs is determined according to the distance value. The distance sensor can be arranged on one side of a screen or one side of a rear shell of the terminal, if the distance sensor is arranged on one side of the screen of the terminal, when the terminal detects that the distance between the distance sensor and the shielding object is smaller than a preset value (for example, 5cm) through the distance sensor, the terminal screen can be determined to face the shielding object, and because in practical application, when a terminal NFC function is used for payment, the terminal needs to be close to an NFC terminal so as to receive NFC radio-frequency signals, when the terminal screen is determined to face the shielding object, the NFC terminal can be determined to be located on one side of the terminal screen, and the received NFC radio-frequency signals are signals of a radio-frequency field on one side of the terminal screen, namely a second radio-frequency field; otherwise, it may be determined that the NFC terminal is located at one side of the rear housing of the terminal, and thus the received NFC radio-frequency signal is a signal of a radio-frequency field at one side of the rear housing of the terminal, i.e., the first radio-frequency field. If the distance sensor is arranged on one side of the rear shell of the terminal, when the terminal detects that the distance between the distance sensor and the shielding object is smaller than a preset value (for example, 5cm) through the distance sensor, it can be determined that the NFC terminal is located on one side of the rear shell of the terminal, and therefore the received NFC radio-frequency signal is a signal of a first radio-frequency field; otherwise, it is determined that the NFC terminal is located at one side of the terminal screen, and thus the received NFC radio-frequency signal is a signal of the second radio-frequency field.
For example, taking the terminal as an example Of receiving an NFC radio frequency signal sent by a Point Of Sale (POS), in the prior art, when a terminal user uses the NFC function Of the terminal to pay, the terminal user can generally receive the NFC radio frequency signal only by approaching one side Of the rear case Of the terminal to the POS machine. The NFC antenna of the terminal described in the embodiment of the invention can transmit and receive NFC radio-frequency signals in both the front direction and the back direction, so that when a terminal user uses the NFC function of the terminal to pay, one side of the rear shell of the terminal can be close to a POS machine to receive the NFC radio-frequency signals, and one side of the screen of the terminal can be close to the POS machine to receive the NFC radio-frequency signals. If one side of the rear shell of the terminal is close to the POS machine to receive the NFC radio-frequency signal, the first NFC antenna receives the NFC radio-frequency signal from a radio-frequency field (a first radio-frequency field) on one side of the rear shell of the terminal; if the screen side of the terminal is close to the POS machine to receive the NFC radio-frequency signal, the NFC radio-frequency signal from the radio-frequency field (second radio-frequency field) on the screen side of the terminal is received by the second NFC antenna. Therefore, by implementing the embodiment of the invention, the NFC radio-frequency signal can be received by enabling one side of the rear shell of the terminal to be close to the POS machine, and the NFC radio-frequency signal can be received by enabling one side of the screen of the terminal to be close to the POS machine, so that the user experience can be improved.
S102, if the terminal judges that the NFC radio frequency signal is the signal of the first radio frequency field, controlling the NFC radio frequency signal to be transmitted to a security module corresponding to the first radio frequency field according to the corresponding relation between a preset radio frequency field and the security module.
S103, if the terminal judges that the NFC radio frequency signal is the signal of the second radio frequency field, the terminal controls the NFC radio frequency signal to be transmitted to a safety module corresponding to the second radio frequency field according to the corresponding relation between the preset radio frequency field and the safety module.
When the terminal judges the radio frequency field to which the NFC radio frequency signal belongs, the terminal determines the safety module corresponding to the judged radio frequency field to which the NFC radio frequency signal belongs according to the corresponding relation between the radio frequency field preset by the terminal and the safety module, and then controls the NFC radio frequency signal to be transmitted to the determined safety module corresponding to the judged radio frequency field to which the NFC radio frequency signal belongs. The corresponding relationship between the radio frequency field preset by the terminal and the security module may be configured already when the terminal leaves the factory, or may be manually configured by a user of the terminal, and the embodiment of the present invention is not limited.
Specifically, if the terminal determines that the NFC radio-frequency signal is a signal of the first radio-frequency field, the terminal determines a security module corresponding to the first radio-frequency field according to a correspondence between a radio-frequency field preset by the terminal and a security module, and then controls to transmit the NFC radio-frequency signal to the determined security module corresponding to the first radio-frequency field. If the terminal judges that the NFC radio-frequency signal is the signal of the second radio-frequency field, the security module corresponding to the second radio-frequency field is determined according to the corresponding relation between the radio-frequency field preset by the terminal and the security module, and then the NFC radio-frequency signal is controlled to be transmitted to the determined security module corresponding to the second radio-frequency field.
In some possible embodiments, the correspondence between the preset radio frequency field of the terminal and the security module may be stored in the form of a mapping table. Specifically, no matter the corresponding relationship between the radio frequency field configured before leaving the factory or the radio frequency field configured manually by the terminal user and the security module, the corresponding relationship between the configured radio frequency field and the security module is recorded in the mapping table after the corresponding relationship configuration is completed, and the mapping table is stored, so that when the terminal determines the radio frequency field to which the NFC radio frequency signal belongs, the security module corresponding to the determined radio frequency field to which the NFC radio frequency signal belongs can be determined by querying the mapping table.
In some possible embodiments, the specific process of presetting the correspondence between the radio frequency field and the security module is that the terminal first obtains the identifier of each security module in the terminal and obtains the identifier of the radio frequency field. The identifier of the security module may be set by the terminal by using different characters according to the location area where the security module is located, for example, the identifier of the security module in the SIM card 1 is set to SE1, and the identifier of the security module in the SIM card 2 is set to SE 2; or the terminal may acquire the hardware address of each security module by scanning the hardware device, and use the acquired hardware address as the identifier of the security module. The identification of the radio frequency field may be manually configured by the end user, for example, by popping up a configuration box for the end user to manually input the identification of the radio frequency field, the end user may set the identification of the radio frequency field on the back case side of the terminal to RF1 and the identification of the radio frequency field on the screen side of the terminal to RF 2. Then outputting a configuration display interface, wherein the configuration display interface comprises the identifiers of at least two security modules and the identifier of the radio frequency field; and finally, receiving and storing the configuration relationship of the security module and the radio frequency field input by the terminal user. It can be understood that the radio frequency field identifier may also be set before the terminal leaves a factory, and the corresponding relationship between the preset radio frequency field and the security module may be configured in advance on the terminal configuration interface, or may be configured when receiving the NFC radio frequency signal. The configuration relationship may be stored in a form of a database, or may be stored in other manners, which is not limited in the embodiment of the present invention. Therefore, when the terminal determines the radio frequency field to which the NFC radio frequency signal belongs, the security module corresponding to the determined radio frequency field to which the NFC radio frequency signal belongs can be determined by querying the configuration relationship.
In some possible embodiments, after receiving the NFC radio frequency signal and determining the radio frequency field to which the NFC radio frequency signal belongs, the terminal first determines the identifier of the radio frequency field to which the NFC radio frequency signal received by the terminal belongs according to a preset rule, for example, the preset rule specifies that the identifier of the first radio frequency field is set to RF1 and the identifier of the second radio frequency field is set to RF 2. And simultaneously acquiring the identification of each security module included in the terminal. Then outputting a configuration display interface, wherein the configuration display interface comprises the identifiers of at least two security modules and the identifier of the radio frequency field to which the NFC radio frequency signal received by the terminal belongs; and finally, receiving and storing the configuration relationship of the security module input by the terminal user and the radio frequency field to which the NFC radio frequency signal received by the terminal belongs. Therefore, the terminal can determine the security module corresponding to the determined radio frequency field to which the NFC radio frequency signal belongs by querying the configuration relationship.
In some possible embodiments, before controlling, according to the corresponding relationship between the preset radio frequency field and the security module, to transmit the NFC radio frequency signal to the security module corresponding to the radio frequency field to which the NFC radio frequency signal belongs, the terminal outputs prompt information, where the prompt information is used to prompt a user of the terminal whether to determine, according to the corresponding relationship between the preset radio frequency field and the security module, to control transmission of the NFC radio frequency signal to the security module corresponding to the radio frequency field to which the NFC radio frequency signal belongs; and when the terminal receives a determination instruction input by the terminal user aiming at the prompt message, controlling to transmit the NFC radio frequency signal to a security module corresponding to the judged radio frequency field to which the NFC radio frequency signal belongs according to the corresponding relation between the preset radio frequency field and the security module.
For example, referring to fig. 2 together, assuming that the terminal supports a dual-SIM NFC scheme, that is, a security module exists in both the SIM card 1 and the SIM card 2, the NFC controller may transmit the NFC radio frequency signal received by the NFC antenna to the security module of the SIM card 1 or the SIM card 2. As shown in fig. 2, the terminal includes an NFC antenna, an NFC controller, a security module, and the like, where the security module in the SIM card 1 is a security module 1, and the security module in the SIM card 2 is a security module 2. The NFC antenna is used for receiving or sending NFC radio frequency signals and is connected with the NFC controller; the NFC controller is used for receiving NFC radio frequency signals from different directions of the NFC antenna and can be used for modulating and demodulating the NFC radio frequency signals. The terminal is preset with a corresponding relationship between the radio frequency field and the security module, and takes the example that the first radio frequency field corresponds to the security module 1 and the second radio frequency field corresponds to the security module 2. When the terminal receives an NFC radio frequency signal, a distance value between the distance sensor and a shielding object is obtained through the distance sensor arranged on the terminal, and then a radio frequency field to which the NFC radio frequency signal belongs is determined according to the distance value. If the NFC radio-frequency signal is determined to be a signal of the first radio-frequency field, the NFC controller transmits the NFC radio-frequency signal to the security module 1. The dashed arrow in fig. 2 is a process of controlling, by the NFC controller, the NFC radio-frequency signal to be transmitted to the security module 1 according to the correspondence between the preset radio-frequency field and the security module when it is determined that the NFC radio-frequency signal is a signal of the first radio-frequency field. If the NFC radio-frequency signal is determined to be a signal of the second radio-frequency field, the NFC controller transmits the NFC radio-frequency signal to the security module 2. The solid arrow in fig. 2 is a process of controlling, by the NFC controller, the NFC radio-frequency signal to be transmitted to the security module 2 according to the correspondence between the preset radio-frequency field and the security module when it is determined that the NFC radio-frequency signal is a signal of the second radio-frequency field. Therefore, in practical application, if a terminal user wants to perform mobile payment through the SIM1, the terminal user only needs to directly approach one side of the mobile phone rear shell to the external accepting device to receive the signal of the first radio frequency field, and if the terminal user wants to perform mobile payment through the SIM card 2, the terminal user only needs to directly approach one side of the mobile phone screen to the external accepting device to receive the signal of the second radio frequency field. Therefore, the embodiment of the invention is convenient and simple, and can improve the user experience. It should be noted that, because the security module is disposed in the SIM card, the method according to the embodiment of the present invention can be implemented no matter the terminal is in a power-on state or a power-off state.
According to the embodiment of the invention, when the NFC radio-frequency signal is received, the radio-frequency field to which the NFC radio-frequency signal belongs is judged, and the NFC radio-frequency signal is controlled to be transmitted to the safety module corresponding to the judged radio-frequency field to which the NFC radio-frequency signal belongs according to the corresponding relation between the preset radio-frequency field and the safety module, so that the NFC radio-frequency signal is automatically and quickly transmitted to the corresponding safety module, and the automation and intellectualization of signal processing based on NFC are realized.
Referring to fig. 3, a schematic flowchart of a method for processing a signal based on NFC according to another embodiment of the present invention is shown, where the method may be applied to a terminal with an NFC function and at least two security modules, such as a smart phone, a tablet, a mobile internet device, and a wearable device. An NFC-based signal processing method as shown in fig. 3 may include the steps of:
s201, when the terminal receives an NFC radio frequency signal, the NFC antenna to which the NFC radio frequency signal belongs is judged.
The NFC antenna of the terminal can receive signals of the first radio frequency field and the second radio frequency field, and of course, the terminal can also receive signals of other radio frequency fields. The first radio frequency field is a radio frequency field at one side of the rear shell of the terminal; the second radio frequency field is a radio frequency field at one side of the terminal screen. The terminal comprises a first NFC antenna and a second NFC antenna, an isolation layer is arranged between the first NFC antenna and the second NFC antenna, and the NFC antenna and the antenna matching circuit of the terminal are adjusted and improved before the terminal leaves a factory, so that signals of the first radio frequency field can only be received by the first NFC antenna, and signals of the second radio frequency field can only be received by the second NFC antenna.
The NFC antenna matching circuit includes an antenna matching circuit 1 and an antenna matching circuit 2, and only NFC radio-frequency signals received by a second NFC antenna included in the terminal can be transmitted to the NFC controller through the antenna matching circuit 1, and only NFC radio-frequency signals received by a first NFC antenna included in the terminal can be transmitted to the NFC controller through the antenna matching circuit 2. Therefore, when the NFC controller of the terminal receives the NFC radio-frequency signal transmitted by the antenna matching circuit 1, it can be determined that the first NFC antenna receives the NFC radio-frequency signal; when the NFC controller of the terminal receives the NFC radio-frequency signal transmitted by the antenna matching circuit 2, it can be determined that the second NFC antenna receives the NFC radio-frequency signal.
