Abstract
The present invention relates to an electronic device and a method of operating the electronic device. There are provided an electronic device and a method of operating the electronic device that may more effectively resolve handover request collisions by using a specific field value included in a handover request message.
Claims52
A method of establishing a communication link between a first electronic device and a second electronic device, comprising:
- transmitting to the second electronic device an NFC handover request message for establishing communication between the first device and the second device using an alternative carrier for at least one alternative communication link, wherein the NFC handover request message includes a provision for collision resolution information;
- and
- receiving an NFC handover select message from the second device, wherein the NFC handover select message includes a provision for power state information.
A first electronic device comprising:
- an NFC communication module configured to transmit to the second electronic device a handover request message for establishing communication between the first device and a second device using an alternative carrier for at least one alternative communication link, wherein the handover request message includes a provision for collision resolution information;
- the NFC communication module also configured to receive a handover select message from the second device, wherein the handover select message includes a provision for power state information;
- and
- an alternative communication module configured to establish the communication between the first device and the second device using the alternative carrier.

A method performed by a first electronic device, comprising:
- transmitting to a second electronic device, via an NFC communication module of the first electronic device, a handover request message for establishing an alternative communication link between the first electronic device and the second electronic device using an alternative carrier, wherein the handover request message comprises a collision resolution record including a random number;
- and
- receiving from the second electronic device, via the NFC communication module of the first electronic device, a handover select message, wherein the handover select message comprises alternative carrier power state information;
- and
- establishing via an alternative communication module of the first electronic device, the alternative communication link between the first device and the second device using the alternative carrier, wherein the alternative carrier is Bluetooth.
