Abstract
The present invention provides an information processing method and an NFC terminal. The method includes: monitoring a state of a TCP connection that is established by at least one secure element SE in a near field communication NFC terminal to a server by using a Transmission Control Protocol TCP port of the NFC terminal; when monitoring that the state of the TCP connection is disconnected, determining a first SE from the at least one SE, where the first SE is an SE corresponding to a TCP port whose TCP connection is disconnected; and obtaining an application identifier AID of a contactless application in the first SE.
Claims22
An information processing method, comprising:
- monitoring a state of a Transmission Control Protocol (TCP) connection established by at least one secure element (SE) in a near field communication (NEC) terminal to a server by using a TCP port of the NFC terminal;
- when monitoring that the state of the TCP connection is disconnected, determining a first SE from the at least one SE, wherein the first SE is an SE corresponding to a TCP port whose TCP connection is disconnected;
- and
- obtaining an application identifier (AID) of a contactless application in the first SE.
An information processing method, comprising:
- receiving application change notification information sent by a server;
- and
- obtaining an application identifier (AID) of a contactless application in a first secure element (SE), wherein the first SE in an SE in a near field communication LNFC) terminal and that communicates with the server.
14-17. (canceled)
A near field communication (NFC) terminal, comprising:
- a secure element (SE) interface, configured to connect an SE to the NFC terminal;
- a non-volatile memory, configured to store an application identifier (AID) of a contactless application in the SE;
- a Transmission Control Protocol (TCP) port;
- and
- a processor, connected to the non-volatile memory, the SE interface, and the TCP port by using a bus, and configured to:
- monitor a state of a TCP connection that is established by at least one secure element SE in a near field communication NFC terminal to a server by using a Transmission Control Protocol TCP port of the NFC terminal, when monitoring that the state of the TCP connection is disconnected, determine a first SE from the at least one SE, wherein the first SE is an SE corresponding to a TCP port whose TCP connection is disconnected, and
- obtain an AID of a contactless application in the first SE.
