Abstract: A system (211) and method (300) for reliable monitoring of secure application execution events is provided. The system can include a Near Field Communication (NFC) modem (140) for communicating transaction events of a secure contactless transaction (358) with a NFC reader (170), a secure controller (200) for monitoring state transitions caused by the transaction events, and a mobile host communicatively coupled to the secure controller for receiving hardware event notifications of the state transitions. The secure controller can generate message using a hardware interrupt to a mobile host based on secure applet state transition monitoring by setting up the events flag such as a Transaction Completion Flag (TCF) (372) into an Events Status Register (232) to identify a status of a secure contactless transactions.

Abstract: In a portable electronic device (100) having a plurality of near field communication applications stored within a plurality of execution environments, automatic selection of one of the near field communication applications is performed by a protocol discovery manager (319) and an application discovery manager (316). The application discovery manager (316) is disposed within a default execution environment. The protocol discovery manager (319), which operates in a near field communication circuit controller (301), performs application discovery at the mode switch level (321), the collision detection level (322), and the protocol level (323). The application discovery manager (316) performs application discovery at the application level. Where the protocol discovery manager (319) selects an application, it can configure a routing switch (219) to route data to the appropriate execution environment and launches the selected application, where only protocol level of identification is required.

Abstract: A method, a tap initiator, and tap target in a close proximity communication are disclosed. A tap interface 106 may initiate a tap with a tap target 104. The tap interface 108 may receive a tap from a tap initiator 102. A tap gauge 110 may measure a tap duration between the tap initiator 102 and the tap target 104. A processor 304 may determine if the tap duration is within a first duration range and a second duration range and executes a first action for the first duration range and a second action for the second duration range.

Abstract: In a portable electronic device (100) having a plurality of near field communication applications stored within a plurality of execution environments, an application discovery manager (311) is configured to automatically select and launch one or more of the near field communication applications. A near field communication circuit (300) receives a near field communication request from an external near field communication device (700). The application discovery manager (311) identifies a near field communication technology, a protocol, and an application identifier and then references a registry table (313) to determine identification parameters corresponding with the identified information. The application discovery manager (311) then selects a near field communication application and launches it. The application discovery manager (311) further configures a routing switch (316) to direct data between the near field communication circuit controller (301) and the appropriate execution environment.

Abstract: An embodiment relates generally to a method of selecting applications. The method includes positioning a powered-down mobile device into a close proximity of a near field communication device and selecting an application from a plurality of applications stored on the powered-down mobile device. The method also includes executing the application in the powered-down mobile device to interact with the near field communication device.

Abstract: A system (211) and method (400) for reliable monitoring of secure applet events is provided. The system can include a Near Field Communication (NFC) modem (140) for communicating transaction events, a secure controller (200) for monitoring state transitions caused by the transaction events, and a mobile host (125) for receiving event notifications of the state transitions via an Applications Programming Interface. An NFC reader can send a Transaction Acknowledgement TACK (403) to the NFC modem to confirm a receipt of data associated with an applet event. An INFO message (405) can be included with the TACK for informing a user of secure contactless transaction status through a user interface (190) of the mobile host.

Abstract: A method for power resource management in a portable communication device includes a first step (200) of defining power profiles of a plurality of operational modes of the communication device. A next step (202) includes calculating available power. A next step (204) includes inputting operating parameters of a selected operational mode. A next step (206) includes predicting whether there is sufficient power to operate the selected mode before entry therein, such that, if there is insufficient power, restricting (208) operation of one of the operational modes before entry into the selected mode, thereby preemptively preventing problems that can occur when power becomes exhausted in a portable device.
