1. A method of establishing a communication link between a first electronic device and a second electronic device, the method comprising:
- transmitting to the second electronic device a first handover request message including plural alternative carrier information for respective plural alternative communication links;
receiving a first handover select message including plural alternative carrier information for the plural alternative communication links from the second electronic device in response to the first handover request message;
wherein the first handover request message includes collision resolution information and each of the plural alternative carrier information of the first handover select message includes first power state information being set to an inactive state;
transmitting a second handover request message including the carrier information for one of the plural alternative communication links to the second electronic device;
receiving a second handover select message from the second electronic device transmitted in response to the second handover request message;
wherein the second handover select message includes second power state information of the one of the plural alternative carrier information of the one of the plural alternative communication links, the second power state information being set to an active state; and
establishing the communication link based on the one of the plural alternative carrier information.

10. Apparatus in a first electronic device for establishing a communication link between the first electronic device and a second electronic device, the apparatus comprising:
-
a transmitter configured to transmit to the second electronic device a first handover request message including plural alternative carrier information for respective plural alternative communication links; a receiver configured to receive from the second electronic device a first handover select message including plural alternative carrier information for the plural alternative communication links in response to the first handover request message; wherein the first handover request message includes collision resolution information and each of the plural alternative carrier information of the first handover select message includes first power state information being set to an inactive state; the transmitter configured to transmit to the second electronic device a second handover request message including the alternative carrier information for one of the plural alternative communication links; the receiver configured to receive from the second electronic device a second handover select message in response to the second handover request message; wherein the second handover select message includes second power state information of the one of the plural alternative carrier information for the one of the plural alternative communication links, the second power state information being set to an active state; and a controller configured to establish the communication link based on the one of the plural alternative carrier information. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
