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. Where other levels are required, the protocol discovery manager (319) selects and routes data to the default execution environment containing application discovery manager (316). The application discovery manager (316), upon selecting an application, can either launch the application or forward a message to the appropriate execution environment for further execution as required by the selected application.

Claims

a near field communication circuit having a near field communication circuit controller operable with the near field communication circuit;

a plurality of near field communication applications stored in one or more execution environments, each being operable with the near field communication circuit controller, wherein at least one of the plurality of near field communication applications is stored within a default execution environment; and

a protocol discovery manager, operable with the near field communication circuit controller, configured to identify a near field communication technology associated with an external near field communication device at a protocol level, a near field communication technology level, and a collision detection level, and to select the default execution environment based upon the near field communication technology;

wherein the default execution environment comprises an application discovery manager configured to select one of the plurality of near field communication applications at a level other than the protocol level the technology level, or the collision detection level.

2. The portable electronic device of claim 1, wherein the application discovery manager further comprises a message-forwarding module configured to transmit an application discovery message from the default execution environment to an other of the one or more execution environments.

3. The portable electronic device of claim 1, wherein the portable electronic device further comprises an interface switch, operable with the near field communication controller, configured to selectively route data communication between the near field communication circuit controller and the one or more execution environments.

4. The portable electronic device of claim 3, wherein the application discovery manager and the protocol discovery manager are each configured with an ability to transmit a switch configuration message to the near field communication circuit controller to direct the interface switch to route the data communication between the near field communication circuit controller and an execution environment associated with the one of the plurality of near field communication applications.

5. The portable electronic device of claim 1, wherein each of the one or more execution environments comprises an application manager configured to manage execution of near field communication applications stored therein, wherein the application discovery manager, stored within one of the one or more execution environments, comprises a message forwarding module configured to transmit an application discovery forwarding message to the application manager in at least one other of the one or more execution environments.

6. The portable electronic device of claim 5, wherein the application discovery manager further comprises registry table of the plurality of near field communication applications residing within the plurality of execution environments, the registry table comprising at least a near field communication application identifier associated with each of the plurality of near field communication applications, and at least one element identifier associated with another of the one or more execution environments.

7. The portable electronic device of claim 6, wherein the application discovery forwarding message comprises the at least one element identifier corresponding to one of the one or more execution environments.

8. The portable electronic device of claim 7, wherein the application discovery forwarding message further comprises a status of application discovery, and a current level of application discovery.

9. The portable electronic device of claim 1, wherein the one or more execution environments comprises a plurality of secure elements, wherein the default execution environment comprises one of the plurality of secure elements, further wherein near field communication applications discoverable by the application discovery manager are stored within a default secure element.

10. The portable electronic device of claim 9, wherein the protocol discovery manager is configured to activate the one of the plurality of secure elements, while the application discovery manager is configured to activate the at least another of the plurality of secure elements.

11. In a portable electronic device having near field communication capabilities and a plurality of near field communication applications stored in a plurality of execution environments, a method for automatically selecting one or more near field communication applications comprising the steps of:

detecting an external near field communication device;

identifying a near field communication technology at a protocol level, a technology level, and an anticollision level;

selecting a default execution environment having an application discovery manager and a registry table stored therein based upon the near field communication application identifier;

executing the near field communication application.

12. The method of claim 11, wherein the plurality of execution environments comprise a plurality of secure elements, further comprising the step of referencing the registry table to determine a secure element in which the near field application resides.

13. The method of claim 12, further comprising the step of directing data communication through an interface switch from the default execution environment to the secure element in which the near field application resides.

14. The method of claim 13, further comprising the step of initializing the secure element in which the near field communication application resides.

15. In a default execution environment, operable with a near field communication controller, a method for selecting a near field communication application from a plurality of near field communication applications stored within one or more execution environments, the method comprising the steps of:

transmitting file control information associated with the enabled near field communication applications through the near field communication controller, wherein the file control information comprises a list of application identifiers associated with the enabled near field communication applications;
