## Abstract

Embodiments of a method and system are disclosed. One embodiment is a method for controlling operations in a mobile communication device that is enabled for near field communication (NFC). The method involves starting an NFC service in the mobile communication device, starting an initialization process of a secure element (SE), e.g., a Universal Integrated Circuit Card (UICC), of the mobile communication device in response to starting the NFC service, and once the initialization process of the SE has begun, monitoring an SE-specific session ID for an indication of the status of the initialization process of the SE. If the SE-specific session ID indicates that the initialization process is not complete, the method involves continuing to monitor the SE-generated session ID and if the SE-specific session ID indicates that the initialization process is complete, the method involves notifying the NFC service that the initialization process of the SE is complete.

## Claims

### Claim 1

A method for controlling operations in a mobile communication device that is enabled for near field communication (NFC), the method comprising:
starting an NFC service in the mobile communication device;
starting an initialization process of a secure element (SE) of the mobile communication device in response to starting the NFC service;
once the initialization process of the SE has begun, monitoring an SE-specific session ID for an indication of the status of the initialization process of the SE;
if the SE-specific session ID indicates that the initialization process is not complete, continuing to monitor the SE-generated session ID; and
if the SE-specific session ID indicates that the initialization process is complete, notifying the NFC service that the initialization process of the SE is complete.

### Claim 2 (depends on 1)

The method of claim 1 further comprising suspending at least one operation of the NFC service until the notification is received.

### Claim 3 (depends on 1)

The method of claim 1 further comprising suspending the sending of commands/interrupts to the SE until the notification is received.

### Claim 4 (depends on 1)

The method of claim 1 further comprising suspending at least one operation of the NFC service while the monitoring of the SE-specific session ID is continued.

### Claim 5 (depends on 1)

The method of claim 1 wherein monitoring the SE-specific session ID comprises reading the SE-specific session ID from an NFC controller after the initialization process has begun and comparing the retrieved SE-specific session ID to a default SE-specific session ID.

### Claim 6 (depends on 5)

The method of claim 5 wherein the SE-specific session ID indicates that the initialization process is complete when the SE-specific session ID that was read after the initialization process began does not match the default value.

### Claim 7 (depends on 6)

The method of claim 6 wherein the default value of the SE-specific session ID is the eight-byte value 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF.

### Claim 8 (depends on 5)

The method of claim 5 wherein the SE-specific session ID is reset to the default value at the NFC controller in response to a command from the SE.

### Claim 9 (depends on 1)

The method of claim 1 wherein monitoring the SE-specific session ID comprises reading the SE-specific session ID from an NFC controller before the initialization process of the SE has begun, retrieving the SE-specific session ID from the NFC controller after the initialization process has begun, and comparing the SE-specific session ID that was read after the initialization process began with the SE-specific session ID that was read before the initialization process began.

### Claim 10

A mobile communication device that is enabled for near field communication (NFC), the mobile communication device comprising:
an NFC service including a terminal host;
an NFC controller including a host controller;
a secure element (SE) including an SE host;
wherein the terminal host, the host controller, and the SE host communicate with each other via a Host Controller Interface (HCI) architecture;
a notification application configured to:
monitor an SE-specific session ID for an indication of the status of an initialization process of the SE;
if the SE-specific session ID indicates that the initialization process of the SE is not complete, continue to monitor the SE-specific session ID; and
if the SE-specific session ID indicates that the initialization process of the SE is complete, notify the terminal host that the initialization process of the SE is complete.

### Claim 11 (depends on 10)

The mobile communication device of claim 10, wherein the terminal host is configured to suspend at least one operation of the NFC service until the notification is received.

### Claim 12 (depends on 10)

The mobile communication device of claim 10, wherein the terminal host is configured to suspend sending commands/interrupts to the SE until the notification is received.

### Claim 13 (depends on 10)

The mobile communication device of claim 10, wherein the NFC service is configured to suspend at least one operation of the NFC service while the monitoring of the SE-specific session ID is continued.

### Claim 14 (depends on 10)

The mobile communication device of claim 10, wherein monitoring the SE-specific session ID comprises reading the SE-specific session ID from the NFC controller.
