Abstract

This application provides a method for invoking a near field communication NFC application, an electronic device, and an NFC apparatus, and relates to electronic device technologies in the artificial intelligence (AI) field. Specifically, the electronic device may learn a rule of using NFC applications by the user, so that when the electronic device approaches an NFC device, the electronic device intelligently predicts a use requirement of the user for the NFC applications based on context awareness in combination with one or more of geographical location information, time information, weather information, motion information, or usage information of the electronic device. In this way, an NFC application group that can meet the user requirement and that is corresponding to a use order is invoked, so that the electronic device automatically verifies, one by one, the NFC devices that are approached by the electronic device.

First claim

What is claimed is:

1. A method applied to an electronic device, wherein the electronic device comprises a plurality of near field communication (NFC) applications, and the method comprises:
obtaining, by the electronic device as the electronic device approaches a first NFC device of a plurality of NFC devices, current scenario information of the electronic device, wherein the current scenario information comprises one or more of geographical location information, time information, weather information, motion information, or usage information, the motion information indicates a motion status of the electronic device, the geographical location information is determined by the electronic device and indicates a geographical location of the electronic device, and the usage information indicates information about the electronic device using NFC applications within a preset time range prior to a time indicated by the time information;
predicting, by the electronic device based on an analysis of the current scenario information performed by the electronic device, a first NFC application group to be invoked and a use order corresponding to the first NFC application group, wherein the first NFC application group comprises n NFC applications of the plurality of NFC applications, n≥2, and n is a positive integer, the use order indicates an order of the n NFC applications in the first NFC application group, and each one of the n NFC applications corresponds to a different one of the plurality of NFC devices; and
sequentially invoking, by the electronic device, the n NFC applications in the first NFC application group based on the use order corresponding to the first NFC application group,
wherein each of the plurality of NFC applications has an emulation function of emulating a non-contact integrated circuit (IC) card.

2. The method according to claim 1 , wherein sequentially invoking, by the electronic device, the n NFC applications in the first NFC application group based on the use order corresponding to the first NFC application group comprises:
activating, by the electronic device, an i th NFC application in the first NFC application group, wherein i is a positive integer, and i<n;
verifying, by the electronic device, the i th NFC application when approaching an NFC device, of the plurality of NFC devices, corresponding to the i th NFC application; and
activating, by the electronic device, an (i+1) th NFC application after verification of the i th NFC application succeeds.

3. The method according to claim 2 , wherein the i th NFC application is an i th invoked NFC application in the first NFC application group in a usage scenario corresponding to usage scenario information of the first NFC application group, and the (i+1) th NFC application is an (i+1) th invoked NFC application in the first NFC application group in the usage scenario corresponding to the usage scenario information of the first NFC application group, wherein
the usage scenario information matches the current scenario information, and the usage scenario information comprises one or more of geographical location information, time information, weather information, motion information, or operation information of the electronic device when the n NFC applications in the first NFC application group are invoked.

4. The method according to claim 2 , wherein when the verifying of the i th NFC application fails, the method further comprises:
sequentially activating, by the electronic device, other NFC applications other than the i th NFC application in the first NFC application group until verification of a NFC application in the first NFC application group succeeds.

5. The method according to claim 4 , wherein the method further comprises:
in a process in which the electronic device sequentially activates the other NFC applications other than the i th NFC application in the first NFC application group, recording, by the electronic device, usage scenario information when the electronic device uses NFC applications;
updating, by the electronic device based on the usage scenario information recorded by the electronic device when the electronic device uses the NFC applications, a rule of using the NFC applications by a user; and
updating, by the electronic device based on an updated rule of using the NFC applications by the user, an NFC application group that matches the current scenario information.

6. The method according to claim 4 , wherein after sequentially activating, by the electronic device, the other NFC applications other than the i th NFC application in the first NFC application group until the verification of the NFC application succeeds, the method further comprises:
sequentially activating and invoking, by the electronic device, NFC applications in a second NFC application group based on a use order corresponding to the second NFC application group, wherein the second NFC application group is different from the first NFC application group, and corresponds to usage scenario information that has highest matching degree with the current scenario information among a plurality of NFC application groups comprising the first NFC application group and the second NFC application group; or
displaying, by the electronic device, a second interface, through which a to-be-switched NFC application group in the plurality of NFC application groups is selected by a user; and in response to an operation of selecting a third NFC application group by the user on the second interface, sequentially activating and invoking, by the electronic device, NFC applications in the third NFC application group based on a use order corresponding to the third NFC application group.

7. The method according to claim 1 , wherein before sequentially invoking, by the electronic device, the n NFC applications in the first NFC application group based on the use order corresponding to the first NFC application group, the method further comprises:
displaying, by the electronic device, a first interface, through which a user determines whether to use the first NFC application group; and
receiving, by the electronic device, an operation of determining, by the user on the first interface, to use the first NFC application group; and
wherein sequentially invoking, by the electronic device, the n NFC applications in the first NFC application group based on the use order corresponding to the first NFC application group comprises:
in response to the operation of determining, by the user on the first interface, to use the first NFC application group, sequentially activating and invoking, by the electronic device, the n NFC applications in the first NFC application group based on the use order corresponding to the first NFC application group.

8. The method according to claim 7 , wherein the first interface comprises information that reminds the user of the use order of the n NFC applications in the first NFC application group.

9. The method according to claim 1 , wherein the electronic device pre-stores a plurality of NFC application groups, and each NFC application group comprises NFC applications; and
predicting, by the electronic device based on the analysis of the current scenario information performed by the electronic device, the first NFC application group comprises:
predicting, by the electronic device based on the analysis of the current scenario information performed by the electronic device, the first NFC application group from the plurality of NFC application groups pre-stored in the electronic device, with the first NFC application group corresponding to usage scenario information that has highest matching degree with the current scenario information among the plurality of NFC application gro
