Description
Technical Field
The present disclosure relates to the field of near field communication technologies, and in particular, to a route processing method, a route processing apparatus, a storage medium, and an electronic device.
Background
Near Field Communication (NFC), also called short-range wireless Communication, is a short-range high-frequency wireless Communication technology that allows contactless point-to-point data transmission between electronic devices. As an important application of near field communication, card simulation may simulate a terminal device (e.g., a mobile phone, a smart watch, etc.) into one card, such as a bus card, a bank card, a door access, various membership cards, etc.
In the card simulation process, the terminal device needs to search for a corresponding Application by relying on an Application Identifier (AID) to realize the corresponding function of the card simulation. With the diversified development of life, the applications simulated by the card on the terminal equipment are more and more, and the number of the corresponding application identifications is more and more.
The storage space for storing the application identifier in the near field communication controller is limited, and once the storage space is full, if a new application identifier exists, the new application identifier cannot be written. Some techniques address this problem by writing a new application id in a manner that overwrites the old application id. However, these methods all cause the problem that the user cannot use the card emulation function normally, and thus cannot pay normally, and cannot verify the identity.
It is to be noted that the information disclosed in the above background section is only for enhancement of understanding of the background of the present disclosure, and thus may include information that does not constitute prior art known to those of ordinary skill in the art.
Disclosure of Invention
The present disclosure is directed to a routing processing method, a routing processing apparatus, a storage medium, and an electronic device, so as to overcome, at least to a certain extent, a problem of failure of a terminal device card simulation function due to excessive application identifiers.
According to one aspect of the present disclosure, there is provided a routing processing method applied to a terminal device, the terminal device including a near field communication controller and a plurality of security modules, the routing processing method including: determining the application identifier storage capacity of each security module; if the application identifier storage capacity of a first target module in the plurality of security modules is larger than the capacity of a routing table in the near field communication controller, determining the total storage capacity of the application identifiers of the other security modules except the first target module in the plurality of security modules; and if the total storage capacity of the application identifications of the rest security modules is less than or equal to the capacity of the routing table in the near field communication controller, writing the application identifications of the rest security modules into the routing table of the near field communication controller, and establishing a mapping relation between the first target module and the default route.
According to an aspect of the present disclosure, there is provided a route processing apparatus applied to a terminal device including a near field communication controller and a plurality of security modules, the route processing apparatus including: the first storage capacity determining module is used for determining the application identifier storage capacity of each security module; a second storage capacity determining module, configured to determine, if the storage capacity of the application identifier of a first target module in the multiple security modules is greater than the capacity of the routing table in the near field communication controller, a total storage capacity of the application identifiers of the other security modules except the first target module in the multiple security modules; and the first routing processing module is used for writing the application identifications of the rest of the security modules into the routing table of the near field communication controller and establishing the mapping relation between the first target module and the default route if the total storage capacity of the application identifications of the rest of the security modules is less than or equal to the capacity of the routing table in the near field communication controller.
According to an aspect of the present disclosure, there is provided a storage medium having stored thereon a computer program which, when executed by a processor, implements the above-described route processing method.
According to an aspect of the present disclosure, there is provided an electronic device including: a processor; and a memory for storing executable instructions for the processor; wherein the processor is configured to perform the above-described route processing method via execution of executable instructions.
In the technical solutions provided in some embodiments of the present disclosure, if the application identifier storage amount of one security module is greater than the capacity of the routing table in the near field communication controller, and the total storage amount of the application identifiers of the remaining security modules of the terminal device except the security module is less than or equal to the capacity of the routing table, the application identifiers of the remaining security modules are written into the routing table, and a mapping relationship between the security module and a default route is established. Therefore, when the application identifier selection instruction is received, if the application identifier corresponding to the application identifier selection instruction cannot be searched through the routing table in the near field communication controller, the service content corresponding to the instruction can be routed to the security module which establishes the mapping relation with the default route so as to execute the corresponding service content. The method and the device for realizing the NFC card simulation have the advantages that on the basis of the routing table of the near field communication controller, the default routing scheme is implemented, the application range of the terminal device for realizing the NFC card simulation is greatly expanded, and the problem that new application identification cannot be normally written due to the limitation of the storage capacity of the routing table is solved. In addition, on the basis of the exemplary embodiment of the present disclosure, since the application scene of the card simulation can be expanded, the functions of the terminal device can be enriched, and the behavior activities of people are more convenient.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure.

Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the disclosure. One skilled in the relevant art will recognize, however, that the subject matter of the present disclosure can be practiced without one or more of the specific details, or with other methods, components, devices, steps, and the like. In other instances, well-known technical solutions have not been shown or described in detail to avoid obscuring aspects of the present disclosure.
Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor devices and/or microcontroller devices.
The flow charts shown in the drawings are merely illustrative and do not necessarily include all of the steps. For example, some steps may be decomposed, and some steps may be combined or partially combined, so that the actual execution sequence may be changed according to the actual situation. In addition, the terms "first," "second," "third," "fourth," "fifth," etc. used below are for purposes of distinction only and are not to be construed as limiting the present disclosure.
The security module (SE) described in the present disclosure may also be referred to as a security Element, which is a generic term of a hardware security Element embedded with a microchip, and can independently implement functions such as small-scale computation and storage, and generally has high security. The application field of the security Module is wide, and for example, the security Module can be applied to various fields in the form of a financial integrated circuit card, a Subscriber Identity Module (SIM) card, a bank U shield, a transportation card, an electronic passport, and the like.
The application program running in the security module may be referred to as a security module application (SE application) and is denoted as an Applet or SE Applet. Typically, one or more applets may run on the security module. For example, the financial integrated circuit card runs a payment application of a bank, and the traffic integrated circuit card runs a bus payment application. With the increasing powerful functions of terminal devices, the application of security modules in terminal devices is also increasing. For example, applets such as a bus payment application, a bank payment application, a membership card identification application, and the like are installed on a security module of a mobile phone, so that a user can easily realize corresponding functions such as bus payment, bank payment, membership authentication, and the like through the mobile phone.
Although the terminal device described in the present disclosure generally refers to a mobile phone, it should be understood by those skilled in the art that the terminal device may also include devices such as a smart watch, a tablet, etc., and the present disclosure is not limited thereto.
A terminal device configured with a near field communication card mode function may generally include an Application Processor (AP), a near field communication controller (NFC controller), and a security module. The security module includes, but is not limited to, an Embedded security module (ESE), a Secure digital Card (i.e., an SD Card used as an NFC security module, recorded as uSD), a SIM Card, a Host-based Card Emulation (HCE), and the like.
In an exemplary embodiment of the present disclosure, the application processor and the nfc controller may be coupled via an I2C bus, the nfc controller and the security module may be coupled via an SWP (Single Wire Protocol) bus, and the application processor and the security module may be coupled via an SPI (Serial Peripheral Interface).
In addition, the near field communication controller is configured with a routing table of an Application Identifier (AID), and the present disclosure does not make any special limitation on the components of the entries in the routing table. The application identifier according to the exemplary embodiment of the present disclosure may be composed of a registered application provider identifier (RID) and an extended dedicated application identifier (PIX), and it is easily understood that one application corresponds to one application identifier.
Fig. 1 schematically illustrates a POS (Point Of Sale) payment scenario as an example. And the POS terminal sends an application identifier selection instruction (Select AID instruction), an NFC controller of the terminal equipment receives the instruction, searches a corresponding application identifier in a routing table, and determines a corresponding Applet according to the application identifier. In this case, the NFC controller may send the corresponding service data to the corresponding Applet through the SWP interface to implement the corresponding card simulation function.
Based on factors such as cost, chip size, power consumption and efficiency, the storage space of the routing table is limited, and taking NXP PN547 (an NFC chip) as an example, the routing table can only store 660 bytes of data. In this case, once the storage space of the routing table is full, if a new application identifier exists, there is a problem that the new application identifier cannot be written. To solve this problem, the new application identity may be written in a manner that overwrites the old application identity. However, these methods all cause the problem that the user cannot use the card emulation function normally, and thus cannot pay normally, and cannot verify the identity.
In view of this, a new route processing method is needed.
It should be understood that the route processing method of the exemplary embodiment of the present disclosure may be implemented by a terminal device, that is, the terminal device may perform the respective steps of the route processing method. In this case, a route processing device described below may be configured in the terminal device.
Fig. 2 schematically shows a flowchart of a route processing method of an exemplary embodiment of the present disclosure. The routing processing method of the exemplary embodiment of the present disclosure is applied to a terminal device, which is a device having a near field communication function and includes a near field communication controller and a plurality of security modules. Referring to fig. 2, the route processing method may include the steps of:
and S22, determining the application identifier storage capacity of each security module.
In an exemplary embodiment of the present disclosure, the security module may include, but is not limited to, an ESE, a ussd, a SIM, a HCE, etc., and the plurality of security modules in the terminal device may refer to at least two of the security modules. In addition, the application identifier storage amount refers to the size of the storage space required for storing the application identifier, and specifically refers to the size of the storage space occupied by the application identifier stored in the routing table of the near field communication controller.
First, the number of application identifications of each security module may be determined. In one embodiment, because the applications (applets) in the security module have a one-to-one correspondence with the application identifications, the number of applications in the security module can be determined as the number of application identifications. In another embodiment, each security module may be configured with an application identifier summary table related thereto, and the number of application identifiers may be directly determined through the application identifier summary table.
Next, the amount of storage for the individual application identifications may be determined. Specifically, for each application identifier, the information stored in the routing table may be composed of a routing address, an identifier of the application identifier, and control data, that is, an entry of the routing table may be composed of a routing address, an identifier of the application identifier, and control data. For example, in a terminal device including four security modules, the routing address may be 2 bytes, and the routing addresses for the four security modules are represented by 00, 01, 10, and 11, respectively; the identification number of the application identification may be 16 bytes; the control data may be 2 bytes for representing the state of the corresponding application, which may include, for example and without limitation, bright screen lock, off screen, bright screen unlock, and the like. For this example, the storage capacity of a single application identifier is 20 bytes.
However, it should be understood that 20 bytes is only an exemplary storage amount of the application identifier, and the size of the space occupied by the application identifier and the content of the application identifier may also be in other forms, which is not particularly limited in this exemplary embodiment.
And then, determining the application identifier storage amount of the security module according to the number of the application identifiers of the security module and the storage amount of a single application identifier. Specifically, the product of the two may be used as the application identification storage amount of the security module. For example, if there are 10 applets in a security module, corresponding to 10 application identifiers, and the size of the required storage space of each application identifier is 20 bytes, the storage amount of the application identifier of the security module is 200 bytes.
S24, if the application identifier storage capacity of the first target module in the plurality of security modules is larger than the capacity of the routing table in the near field communication controller, determining the total storage capacity of the application identifiers of the other security modules except the first target module in the plurality of security modules.
In an exemplary embodiment of the present disclosure, the capacity of the routing table may also be referred to as the size of the routing table or the upper limit of the routing table, representing the maximum amount of data that the routing table can store. The capacity of the routing table is related to the type of near field communication chip used, i.e. the capacity of the routing table may differ from near field communication chip to near field communication chip. Taking an NXP PN547 chip as an example, the capacity of a routing table in the near field communication controller is 660 bytes.
After determining the application identifier storage amount of each security module in step S22, it is determined whether there is a security module whose application identifier storage amount is greater than the capacity of the routing table. If so, it may be determined to be the first target module.
Next, the total amount of storage of the application identifications of the remaining security modules, except for the first target module, may be determined.
For example, the capacity of the routing table in the nfc controller is 660 bytes, and in the case where the security module includes only ESE, ussd, and SIM, if the application id storage amount of the SIM is 700 bytes, the SIM is taken as the first target module, and ESE and uSD become the above-mentioned remaining modules, and if the application id storage amounts of ESE and uSD are 100 bytes and 300 bytes, respectively, the total storage amount of the application ids of the remaining security modules described in step S24 is 400 bytes.
S26, if the total storage capacity of the application identifications of the rest safety modules is smaller than or equal to the capacity of a routing table in the near field communication controller, writing the application identifications of the rest safety modules into the routing table of the near field communication controller, and establishing a mapping relation between the first target module and a default route.
In an exemplary embodiment of the present disclosure, after determining a total storage amount of the application identifications of the security modules other than the first target module, the total storage amount may be compared with a capacity of a routing table in the near field communication controller.
If the total storage amount is less than or equal to the capacity of the routing table in the near field communication controller, the storage space of the routing table is enough to store the application identifications of the rest security modules. In this case, the application identifications of the remaining security modules may be written into the routing table of the near field communication controller, and as described above, the routing address, the identification number of the application identification, and the control data may be used to form an entry of the routing table. Taking the total storage capacity of the application identifiers of the rest security modules as 400 bytes and the capacity of the routing table as 660 bytes as an example, at this time, a space of 260 bytes is still available in the routing table, and if the storage capacity of a single application identifier is 20 bytes, 13 application identifiers can also be written into the routing table.
For the first target module, a mapping relationship of the first target module to a default route may be established. Establishing such a mapping relationship described in this disclosure means that, when the application identifier corresponding to the application identifier selection instruction is not found in the routing table, the information may be directly routed to the first target module to implement the corresponding payment and verification functions.
For the specific application processing procedure, first, the terminal device may receive an application identifier selection instruction sent by, for example, a POS terminal; next, the terminal device may determine whether an application identifier corresponding to the application identifier selection instruction exists in a routing table of the nfc controller. If the application identifier exists, the safety module can be determined according to the routing address corresponding to the application identifier, so that the corresponding service function is realized by using the Applet in the safety module; if the application identifier does not exist, the Applet corresponding to the application identifier selection instruction can be determined from the first target module based on the established default route so as to realize the corresponding service function.
It should be understood that in the process of implementing service functions (e.g., payment, verification, etc.) by using the near field communication technology, the Android application needs to cooperate with the Applet in the security module, that is, a dual-application architecture is generally used to implement services. Fig. 3 schematically illustrates such a dual application architecture, in which an Applet running in the security module is used to perform operations of actual card emulation, and an Android application running in the application processor provides an interface for interaction with a user, performing operations such as receiving a transaction password input by the user, displaying debit information, and the like.
In addition, when the card emulation application is installed, the terminal device may acquire an Application Identifier (AID) from the installation file, and declare AID data used by the Application Identifier (AID) from the installation file. In this case, the AID information can be filtered out by searching the Android application, and the security module corresponding to the AID information is determined.
According to some embodiments of the present disclosure, if the total storage amount of the application identifiers of the security modules other than the first target module is greater than the capacity of the routing table in the near field communication controller, the terminal device may generate an application identifier culling interface, where the application identifier culling interface includes application identifiers related to all security modules.
The application identification removing interface is used as a man-machine interaction interface and can respond to identification removing operation sent by a user to remove the corresponding application identification. In one example, the identification culling operation may be a user check-in operation for the application identification. In addition, one-time identifier elimination operation of the user can be performed on multiple application identifiers, for example, the user can select multiple application identifiers first and then click an elimination button configured on the interface to accomplish simultaneous elimination of the multiple application identifiers.
It should be noted that the term "culling" in the exemplary embodiments of the present disclosure refers to closing (disable) the application identifier, and if necessary, the user may also restore the culled application identifier through a manual operation.
The terminal equipment can remove the application identification selected based on the identification removing operation of the user from the corresponding safety module, and in the process, if the total storage quantity of the application identifications of all the safety modules is larger than the capacity of the routing table in the near field communication controller, a text prompt can be sent out so that the user can continuously remove the application identifications until the total storage quantity of the application identifications of all the safety modules is smaller than or equal to the capacity of the routing table in the near field communication controller.
Next, the terminal device may write the application identifications of all security modules to the routing table of the near field communication controller.
According to some embodiments of the present disclosure, if the total storage amount of the application identifiers of the security modules other than the first target module is greater than the capacity of the routing table in the near field communication controller, the terminal device may generate an application identifier culling interface.
The terminal device may remove the application identifier selected based on the identifier removal operation of the user from the corresponding security module until the application identifier storage amount of the second target module in all the security modules is greater than the capacity of the routing table in the near field communication controller, and the total storage amount of the application identifiers of the other security modules except the second target module in all the security modules is less than or equal to the capacity of the routing table in the near field communication controller. The second target module may be different from the first target module, however, it is easily understood that the second target module and the first target module may be the same security module without largely eliminating the application identifier related to the first target module by the user.
Next, the terminal device may write the application identifiers of the security modules except for the second target module into a routing table of the nfc controller, and establish a mapping relationship between the second target module and a default route.
According to some embodiments of the present disclosure, if the total storage amount of the application identifications of the remaining security modules except the first target module is greater than the capacity of the routing table in the near field communication controller, the terminal device may determine the frequency of use of each application identification in all the security modules and rank the application identifications based on the frequency of use. The frequency of use may be, for example, the number of times the application identifier is used within one month. It should be noted that the frequency of use is not limited thereto, and those skilled in the art may conceive other frequency of use limitations, which, however, should be considered to fall within the scope of the present invention.
Next, the terminal device may eliminate the application identifiers in the order of the frequency of use from low to high until the total storage amount of the application identifiers of all the security modules is less than or equal to the capacity of the routing table in the near field communication controller.
Subsequently, the terminal device may write the application identifications of all security modules to the routing table of the near field communication controller.
According to some embodiments of the present disclosure, if the total storage amount of the application identifications of the remaining security modules except the first target module is greater than the capacity of the routing table in the near field communication controller, the terminal device may determine the frequency of use of each application identification in all the security modules and rank the application identifications based on the frequency of use.
Next, the terminal device may remove the application identifiers in the order from low frequency to high frequency until the application identifier storage amount of the third target module in all the security modules is greater than the capacity of the routing table in the near field communication controller, and the total storage amounts of the application identifiers of the other security modules except the third target module in all the security modules are less than or equal to the capacity of the routing table in the near field communication controller. However, it is easily understood that, in the process of removing the application identifier according to the usage frequency, if the usage frequency of the application identifier in the first target module is higher, the third target module and the first target module described herein may be the same security module.
Subsequently, the terminal device may write the application identifiers of the security modules except for the third target module into a routing table of the near field communication controller, and establish a mapping relationship between the third target module and a default route.
A routing process of an embodiment of the present disclosure will be explained with reference to fig. 4.
In step S402, the terminal device may count the size of the storage space required by each security module AID; in step S404, the terminal device may determine whether there is a security module, where the size of the storage space required by the AID in the security module exceeds the capacity of the NFC routing table, and if there is no security module, go to step S406, and if there is the security module, go to step S408; in step S406, if the sum of the spaces required by all AIDs is smaller than the capacity of the routing table, writing all AID information into the routing table; in step S408, it is determined whether the sum of the spaces required by the rest of the security modules AID exceeds the routing table capacity, and if so, the process goes to step S410, and if not, the process goes to step S412; in step S410, the terminal device may generate a human-computer interaction interface so that the user can remove some AIDs; in step S412, the security module whose AID required space is larger than the capacity of the routing table is matched with the default route, a mapping relationship between them is established, and the rest of the security modules AIDs are written in the routing table.
It should be noted that although the various steps of the methods of the present disclosure are depicted in the drawings in a particular order, this does not require or imply that these steps must be performed in this particular order, or that all of the depicted steps must be performed, to achieve desirable results. Additionally or alternatively, certain steps may be omitted, multiple steps combined into one step execution, and/or one step broken down into multiple step executions, etc.
Further, a route processing device is also provided in this example embodiment.
Fig. 5 schematically shows a block diagram of a route processing apparatus according to an exemplary embodiment of the present disclosure, which is applied to a terminal device including a near field communication controller and a plurality of security modules. Referring to fig. 5, the route processing apparatus 5 according to an exemplary embodiment of the present disclosure may include a first storage amount determining module 51, a second storage amount determining module 53, and a first route processing module 55.
Specifically, the first storage amount determining module 51 may be configured to determine an application identifier storage amount of each security module; the second storage amount determining module 53 may be configured to determine, if the storage amount of the application identifier of the first target module in the plurality of security modules is greater than the capacity of the routing table in the near field communication controller, a total storage amount of the application identifiers of the remaining security modules in the plurality of security modules except the first target module; the first route processing module 55 may be configured to, if the total storage amount of the application identifiers of the remaining security modules is less than or equal to the capacity of the routing table in the near field communication controller, write the application identifiers of the remaining security modules into the routing table of the near field communication controller, and establish a mapping relationship between the first target module and the default route.
According to the routing processing device of the exemplary embodiment of the disclosure, on the basis of the routing table of the near field communication controller, a default routing scheme is implemented, so that the application range of the terminal device for realizing the simulation of the NFC card is greatly expanded, and the problem that a new application identifier cannot be normally written due to the limitation of the storage capacity of the routing table is solved. In addition, on the basis of the exemplary embodiment of the present disclosure, since the application scene of the card simulation can be expanded, the functions of the terminal device can be enriched, and the behavior activities of people are more convenient.
According to an exemplary embodiment of the present disclosure, referring to fig. 6, the route processing device 6 may further include a second route processing module 61, compared to the route processing device 5.
