It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

 The term "multiple" as used herein refers to two or more.

 Embodiment 1

 As shown in FIG. 1 , a routing method is provided to a terminal according to an embodiment of the present invention, where the method includes:

 101: Acquire a data frame and a current energy state of the terminal.

 Among them, "terminal" refers to the NFC terminal. The NFC terminal can contain one or more SEs, and the status of the SE can be active or deactivated. The SE in this article can be equated with NFCEE (NFC Execution Environment, NFC Execution Environment).

 The NFC terminal may also include a main controller DH and a secondary controller; the DH may specifically be a CPU (Central Processing Unit) of the terminal, and the secondary controller may be an NFCC. Generally, DH can work normally when the terminal is powered on; DH can configure routing table for NFCC, set default SE, and so on. The executor of this embodiment may be an NFC terminal, and may specifically be a DH or a secondary controller in the NFC terminal.

The routing table can contain multiple types of routing items, for example, AID (Application ID, Application Identifier) routing item, NFCID2 (Near Field Communication Identifier 2) routing item, Protocol Routing (Protocol) -Based Routing ), Technology-Based Routing, etc. At present time, the routing table may contain any type of routing item, or may not contain any type. a type of routing entry; specifically, the current time, the routing table may include one or more AID routing entries, and/or one NFCID2 routing entry, and/or one or more protocol routing entries, and/or one or more Technical routing item. Each AID routing entry, protocol routing entry, or technical routing entry points to an SE. One SE can correspond to one or more routing entries of the same type or different types; the NFCID2 routing entry does not point to any SE.

 The state of the routing entry may be a valid state or a failed state. In this document, a set of routing entries in a valid state is referred to as a set of routing entries in a valid state, and a set of routing entries in a failed state is referred to as a set of routing entries in a failed state. .

 The current energy status of the terminal can include: power on state, power off (Switch off ) state, and power off ( Battery Off ) state.

 The terminal can acquire the data frame and the current energy state of the terminal by using the methods in the prior art. Specifically, the step 101 may include: receiving, by the terminal, a data frame sent by the RCLF (Remote Contactless Front).

 102: Determine, from the deactivated security unit SE, an SE that matches both the data frame and the current energy state of the terminal as the target SE.

 The method for determining the "SE" that matches the current energy state of the data frame and the current state of the terminal is related to the routing mode. For the specific implementation, refer to the following embodiments. The "routing method" herein may include, but is not limited to, any one of the following modes: AID routing mode, NFCID2 routing mode, protocol routing mode, and technical routing mode.

 Optionally, the step 102 may include: determining, by using the following at least one condition, an SE that matches the data frame and the current energy state of the terminal as the target SE from the deactivated security unit SE; The conditions include: 1) the current energy state of the terminal is a low power consumption state, and 2) the SE in the active state does not include an SE that matches both the data frame and the current energy state of the terminal.

Exemplarily, when the current energy state of the terminal is a power state of shutdown or a power state of shutdown, the terminal is considered to be in a low power consumption state. If the terminal contains a default SE, the default SE is activated when the terminal is in a low power state. The status of the routing entry corresponding to the default SE is valid. The other SEs are in the deactivated state, and the status of other routing entries is in the invalid state.

 In the foregoing optional manner, when the current energy state of the terminal is a low power consumption state, the method may further include: deactivating a default SE; the default SE is preset, and currently at the terminal The energy state is the SE that is active when the power is low. Specifically: an activation/deactivation command for deactivating the default SE is sent to the default SE, so that the state of the default SE is switched from the activated state to the deactivated state.

 Optionally, before the step 102, the method may further include: determining, by the first routing manner, that the security unit SE of the activation state does not include an SE that matches the current energy state of the data frame and the terminal; The first routing mode includes: AID routing mode, protocol routing mode, and technical routing mode. In this case, the step 102 may include: determining, from the set of routing items in the invalid state, a routing item that matches the current energy status of the data frame and the terminal as a target routing item; and the routing item set in the invalid state. The SE pointed to by the routing entry is in a deactivated state; the SE pointed to by the target routing entry is used as the target SE.

 103 : Activate the target SE.

 Exemplarily, the step 103 may include: the DH or the secondary controller sending an activation/deactivation command for activating the target SE to the target SE, so that the state of the target SE is switched from the deactivated state to the activated state.

 Optionally, before the step 103, the method may further include: when the preset switching policy includes the identifier of the target SE, the target SE is activated; the preset switching policy is used to indicate that the terminal has a handover The authority to activate/deactivate the SE, the handover policy including an identifier of the SE that the terminal can control to switch.

For example, the preset switching policy is generally set in the DH. Specifically, the DH can set a preset switching policy under the instruction of the user, or can automatically control the terminal by controlling the performance of the terminal and the usage of the application by the user. The identity of the switched SE is preset to the switching policy. When the execution subject is a secondary controller, before the target SE is activated, The method further includes: the secondary controller receiving the handover decision of the DH transmission. In this case, the preset execution policy is used to indicate that the secondary controller has the right to switch the activation/deactivation state of the SE, and the handover policy includes the identifier of the SE that the secondary controller can control the handover. Specifically, the DH may send a preset switching policy to the secondary controller at any time before the secondary controller is initialized or the secondary controller performs step 103.

 104: Send the data frame to the target SE after activation.

 Optionally, before the step 104, the method may further include: modifying a state of the target routing entry from a failed state to an active state; in this case, the step 104 may include: using the data frame to be in an active state. The target routing entry is sent to the target SE after activation.

 According to the routing method provided by the embodiment of the present invention, the terminal can determine, from the SE in the deactivated state, the SE that matches the current energy state of the data frame and the terminal as the target SE, and send the data frame to the target SE. In this way, when the application targeted by the data frame is an application in the deactivated SE, the user can use the application normally, thereby improving the user experience.

 Embodiment 2

 As shown in FIG. 2, another routing method provided by the embodiment of the present invention is applied to a terminal, where the method includes:

 201: Acquire a first data frame and a current energy state of the terminal.

 The executor of the embodiment may be an NFC terminal, and may be a DH or a secondary controller in the NFC terminal. It should be noted that, for the related explanation in this embodiment, reference may be made to the foregoing first embodiment. For the specific implementation manner of this embodiment, reference may be made to the following embodiment 2.

202: When the energy status included in the near field communication identifier type NFCID2 routing item matches the current energy status of the terminal, and the first data frame includes an instruction to configure the NFCID2 information table, obtaining the routing item including the supported NFCID2 An NFCID2 information table of a relationship between an SE of the deactivated state and an NFCID2 value corresponding to the SE; the NFCID2 information table is used to cause the terminal to determine a target to which the second data frame is sent SE, the second data frame refers to a data frame after the first data frame that does not include an instruction to configure the NFCID2 information table.

 For example, the terminal determines the specific implementation method of the target SE to which the second data frame is sent according to the NFCID2 information table, and can refer to the NFCID2 routing mode in the prior art, and is not described here.

 Specifically, the step 202 may include: activating an SE of the deactivated state; sending the instruction for configuring the NFCID2 information table to the activated SE; receiving a response message that is sent by the SE and including an NFCID2 value; Generate an NFCID2 information table.

 Optionally, the step 202 may include: obtaining, by using the following at least one condition, an NFCID2 information table that includes a relationship between a SE that supports a deactivated state of the NFCID2 routing item and an NFCID2 value corresponding to the SE. The condition includes: the current energy state of the terminal is a low power consumption state, and the SE in the activated state does not include an SE that matches the current data state of the data frame and the terminal.

 For example, the method for determining whether the terminal includes the SE supporting the NFCID2 routing item in the activation state may refer to the prior art, and is not described here.

 In the routing method provided by the embodiment of the present invention, the NFCID2 information table obtained by the terminal includes a relationship between the SE of the deactivated state supporting the NFCID2 routing item and the NFCID2 value corresponding to the SE, so that when the terminal receives the second data frame, The target SE to which the second data frame is transmitted can be determined from the SE in the deactivated state. In this way, when the application targeted by the second data frame is an application in the SE in the deactivated state, the user can use the application normally, thereby improving the user experience.

 In order to clearly describe the following specific embodiments, the following points are first explained:

 1. The execution entities in the specific embodiment are all NFCC, and the default SE is preset in DH.

2. Since the DH does not work and the NFCC works when the terminal is in a low power state, the advantages of the present invention are better reflected in this case; therefore, the following specific embodiments The technology provided by the present invention is described as an example in a low power consumption state. It should be noted that, in this case, each routing item in the set of routing items in the valid state is a routing item corresponding to the default SE preset by DH.

 Example 1

 In this embodiment, the NFCC determines, according to the AID routing manner, whether the routing table contains a routing entry that matches the data frame acquired by the NFCC. The execution subject of this embodiment is NFCC.

 As shown in FIG. 3, a routing method provided in this embodiment includes:

 301: The NFCC receives the data frame sent by the RCLF, and obtains the current energy state of the NFC terminal.

 Illustratively, the NFCC may obtain the current energy state of the NFC terminal in any of the steps prior to step 304.

 302: When the NFCC determines to use the ISO-DEP (International Standardization Organization-Data Exchange Protocol) interface and the AID routing entry is included in the routing table, the NFCC parses the data frame to obtain the resolution result.

 303: Determine whether the AID value is included in the analysis result.

 If yes, if the data frame satisfies the condition of the AID routing mode, step 304 is performed; if not, it indicates that the data frame does not satisfy the condition for executing the AID routing mode, and then ends.

 304: Determine whether the set of routing entries in the valid state in the routing table includes an AID routing entry that matches the AID value in the parsing result and the current energy state of the NFC terminal.

 If no, it is required to find the AID routing item that matches the AID value in the analysis result and the current energy state of the NFC terminal as the target routing item, and then step 305 is performed; if yes, the description can be used. The prior art method determines the target SE and sends data to the target SE, and then ends.

When step 304 is executed, the NFC terminal may be powered on, powered off, or powered off. 305: Determine whether the current energy state of the NFC terminal is a low power state.

 If yes, go to step 306; if no, end.

 306: Determine whether the routing item set of the invalid state in the routing table includes an AID routing item that matches the AID value in the parsing result and the current energy status of the NFC terminal.

 If yes, go to step 307; if no, it means that there is no AID routing item matching the data frame in the routing table, and the target SE can be determined by using the method in the prior art (for example, according to the routing item specified by the merchant as the target routing item) Or determine the target routing entry by other routing methods, and then determine the target SE), and send data to the target SE, and then terminate.

 For example, the AID routing entry includes: an AID value, an ID of the SE pointed to by the AID routing entry (IDentity, an identity number), and an energy state to which the AID routing entry applies. When the AID value in the analysis result is the same as the AID value included in the AID routing item, and the energy state applicable to the AID routing item is the same as the current energy state of the NFC terminal, the determination result in the step 306 is "Yes"; Otherwise, the judgment result in step 306 is "NO".

 307: The matched AID routing item is used as the target routing item; the SE to which the target routing item is directed is used as the target SE.

 308: Send an activation/deactivation instruction for activating the target SE to the target SE, so that the state of the target SE is switched from the deactivated state to the activated state, and the state of the target routing entry is changed from the invalid state to the valid state; The SE sends an activation/deactivation command for deactivating the default SE, so that the state of the default SE is switched from the activated state to the deactivated state, and the state of the routing entry corresponding to the default SE is changed from the active state to the disabled state.

 When step 308 is performed, "Default SE" is the SE in the set of routing items in the active state. The method can also include: NFCC powering the target SE, stopping powering the default SE.

 309: The data frame is sent to the target SE via the target routing item.

 After step 309 is performed, it ends.

Optionally, steps 304-306 can be replaced by the following steps: Step 1: Determine whether the routing table contains an AID routing entry that matches the AID value and the current energy state of the NFC terminal.

 If yes, step 2 is performed; if no, it indicates that there is no AID routing item matching the data frame in the routing table, and the target SE can be determined by using the method in the prior art, and the data is sent to the target SE, and then the process ends.

 Step 2: Determine whether the current energy state of the NFC terminal is a low power state. If yes, go to step 307; if no, end.

 Optionally, steps 304-307 can be replaced by the following steps:

 Steps: Determine whether the routing table contains an AID routing entry that matches the AID value and the current energy state of the NFC terminal.

 If yes, step 2 ' is performed; if no, it indicates that there is no AID routing item matching the data frame in the routing table, and the target SE can be determined by using the method in the prior art, and the data is sent to the target SE, and then the process ends.

 Step 2 ': Use the matched AID routing entry as the destination routing entry; use the SE pointed to by the destination routing entry as the target SE.

 Step 3 ': Determine if the target SE is the default SE.

 If no, indicating that the current energy state of the terminal is not in the low power state, step 308 is performed; if yes, indicating that the current energy state of the terminal is a low power state, step 309 is performed.

 In the routing method provided by the embodiment of the present invention, when the NFC terminal is in a low power consumption state, the NFCC may determine the AID routing item matching the data frame from the set of routing items in the invalid state in the process of querying the route according to the AID routing manner. The target routing entry, that is, the NFCC can determine the SE matching the data frame as the target SE from the SE in the deactivated state. In this way, when the application targeted by the data frame is an application in the SE in the deactivated state, the user can use the application normally, thereby improving the user experience.

 Exemplarily, the NFCID2 routing entry contains the energy status to which the NFCID2 routing entry applies. Generally, the routing table can contain an NFCID2 routing entry or no NFCID2 routing entry. When the energy status of the NFCID2 routing entry included in the routing table is the same as the current energy status of the NFC terminal, the routing table is considered to contain the NFCID2 routing entry that matches the current energy status of the NFC terminal.

 403 : Determine whether the SENSF REQ ( SENSE TECH F REQUEST ) command is included in the analysis result.

 If yes, it is required to configure the NFCID2 information table, then step 404 is performed; if not, it means that the target SE needs to be determined for the data frame according to the prior art, and then the process ends.

 When an SE does not support the NFCID2 routing entry, the response information returned by the SE to the NFCC includes information that the SE does not support the NFCID2 routing entry. When an SE supports the NFCID2 routing entry, the response information of the SE to the NFCC is returned. Contains the NFCID2 value corresponding to the SE.

 405: Determine whether the NFCID2 value is included in each response message.

If yes, the NFCID2 information table can be configured according to the method in the prior art. Then, if not, step 406 is performed.

 406: Determine whether the current energy state of the NFC terminal is a low power state.

 409: Determine whether the NFCID2 value is included in each response message.

 If yes, go to step 410; if no, the SE in the NFC terminal does not support the NFCID2 routing entry, and the process ends.

 410: The relationship between the SE supporting the NFCID2 routing entry and the NFCID2 value corresponding to each SE supporting the NFCID2 routing entry constitutes an NFCID2 information table.

 After step 410 is performed, it ends.

 Exemplarily, the NFCID2 information table is used to cause the NFCC to determine the target SE to which the second data frame is sent, and the second data frame refers to the first instruction that does not include the configuration NFCID2 information table after the "data frame" in step 401. Data frame. Further, it may be described as follows: when the NFCC receives a data frame again, if the data frame includes the SENSF REQ command, the NFCID2 information table is configured for the data frame according to the method of steps 404-410 above; if the data frame is not Including the SENSF_REQ instruction, the target SE to which the data frame is sent is determined according to the method in the prior art by using the NFDID2 information table determined in step 410.

The specific implementation method for performing the query according to the routing methods listed above may refer to the prior art.

 603: Determine whether the current energy state of the NFC terminal is a low power state.

 If yes, go to step 604; if no, end.
