DUAL IDLE-TRAFFIC STATE OF WIRELESS COMMUNICATION DEVICE
A wireless communication device maintains a dual idle-traffic state where the wireless communication device is in an idle state relative to a first transceiver node and is in a traffic state relative to a second transceiver node. First control signals are received from the first transceiver node and second control signals are received from the second transceiver node where the second control signals are different from the first control signals.
1 . A wireless communication device comprising:
a receiver configured to wirelessly receive first control signals from a first transceiver node and to wirelessly receive, from a second transceiver node, second control signals different from the first control signals;
a controller configured to monitor the first control signals to maintain registration with the first transceiver node while receiving traffic channel signals from the second transceiver node using the second control signals.
2 . The wireless communication device of claim 1 , wherein the receiver is configured to receive the first control signals within one control channel of a dual control channel used by the first transceiver node for transmitting control signals.
3 . The wireless communication device of claim 2 , wherein a modulation order of the one control channel is lower than another modulation order of another control channel of the dual control channel.
4 . The wireless communication device of claim 1 , wherein the first transceiver node provides wireless service within a first node service area larger than a second node service area of the second transceiver node.
5 . The wireless communication device of claim 1 , wherein the receiver is configured to receive a handoff control message from the first transceiver node, the controller configured to process, in response to the handoff control message, a handoff from the second transceiver node to the first transceiver node to invoke reception of traffic channel signals from the first transceiver node.
6 . The wireless communication device of claim 1 , wherein the controller maintains a wireless communication device in a dual idle-traffic state where the wireless communication device is in an idle state relative to the first transceiver node while the wireless communication device is in a traffic state relative to the second transceiver node.
7 . A method comprising:
wirelessly receiving first control signals from a first transceiver node;
wirelessly receiving, from a second transceiver node, second control signals different from the first control signals; and
monitoring the first control signals to maintain registration with the first transceiver node while receiving traffic channel signals from the second transceiver node using the second control signals.
8 . The method of claim 7 , wherein receiving the first control signals comprises receiving the first control signals within one control channel of a dual control channel used by the first transceiver node for transmitting control signals.
9 . The method of claim 8 , wherein a modulation order of the one control channel is lower than another modulation order of another control channel of the dual control channel.
10 . The method of claim 7 , wherein the first transceiver node provides wireless service within a first node service area larger than a second node service area of the second transceiver node.
11 . The method of claim 7 , further comprising:
receiving a handoff control message from the first transceiver node; and
performing a handoff procedure from the second transceiver node to the first transceiver node in response to the handoff control message to invoke reception of traffic channel signals from the first transceiver node.
12 . The method of claim 7 , further comprising:
maintaining the wireless communication device in a dual idle-traffic state where the wireless communication device is in an idle state relative to the first transceiver node while the wireless communication device is in a traffic state relative to the second transceiver node.
13 . A wireless communication system comprising:
a first transceiver node configured to transmit first control signals to a wireless communication device to maintain registration of the wireless communication device within the first transceiver node;
a second transceiver node configured to transmit traffic signals and to transmit second control signals, different from the first control signals, to the wireless communication device.
14 . The wireless communication system of claim 13 , wherein the first transceiver node is further configured to transmit signals within at dual control channel and to transmit the first control signals within one control channel of a dual control channel.
15 . The wireless communication system of claim 14 , wherein a modulation order of the one control channel is lower than another modulation order of another control channel of the dual control channel.
16 . The wireless communication system of claim 13 , wherein the first transceiver node is configured to provide wireless service within a first node service area and wherein the second transceiver node is configured to provide wireless service within a second node service area smaller than the first node service area.
17 . The wireless communication system of claim 13 , wherein the first transceiver node is further configured to send a handoff control message to invoke a handoff of the wireless communication device from the second transceiver node to the first transceiver node to invoke reception of traffic channel signals from the first transceiver node.
18 . The wireless communication system of claim 13 , wherein the first transceiver node is further configured to maintain the wireless communication device in an idles state and the second transceiver node is configured to maintain the wireless communication device in a traffic state while the wireless communication device is in the idle state relative to the first transceiver node.
19 . A wireless communication device configured to maintain an idle state relative to a first transceiver node while maintaining a traffic state with a second transceiver node.
20 . The wireless communication device of claim 19 , wherein the idle state comprises receiving first control signals from the first transceiver node and the traffic state comprises exchanging traffic channel signals with the second transceiver node.
