Abstract

The use of multiple states of mobile communication device operation to allow a single base station to support a relatively large number of mobile nodes is described. Various states require different amounts of communications resources, e.g., bandwidth and/or control signaling. Different numbers of control channels (700) are monitored during different states (702-708) of operation. A mobile node monitors during a first state (702) of operation, e.g., the on-state, a first control channel to detect control signals in segments of the first control channel intended for the mobile node, detects a period of reduced control signaling to said mobile node on said first contro l channel, and then, in response to detecting a period of reduced control sign al signaling to the mobile node, transitions from said first state (702) to a second state (8706) of operation. During the second state (706) of operation fewer control channels are monitored and the first control channel is not monitored.

Claims (20)

1. A method of operating a mobile node capable of operating in a plurality of states of operation, comprising the steps of:
monitoring, during a first state of operation, a first control channel to detect control signals in segments of the first control channel intended for said mobile node, and to detect a period of reduced control signaling to said mobile node on said first control channel;
and in response to detecting a period of reduced control signal signaling to said mobile node on said first control channel, transitioning from said first state of operation to a second state of operation; and wherein transitioning from said first state of operation to the second state of operation includes ceasing to monitor said first control channel.
2. The method of claim 1, further comprising, while in said second state of operation:
monitoring a second control channel to detect control signals in segments of the second control channel intended for said mobile node, and to detect a period of reduced control signaling to said mobile node on said second control channel; and in response to detecting a period of reduced control signal signaling to said mobile node on said second control channel, transitioning from said second state of operation to a third state of operation.
3. The method of claim 2, wherein transitioning from said second state of operation to the third state of operation includes ceasing to monitor said second control channel.
4. The method of claim 2, wherein monitoring said first control channel during said first state of operation includes monitoring said first control channel on a continuous basis.
5. The method of claim 4, wherein said second control channel is a non-continuous control channel including at least some control segments dedicated to said mobile node.

and means for transitioning from said first state of operation to a second state of operation in response to detecting a period of reduced control signal signaling to said mobile node on said first control channel, wherein transitioning from said first state of operation to the second state of operation includes ceasing to monitor said first control channel.
16. The device of claim 15, further comprising, while in said second state of operation:
means for monitoring a second control channel to detect control signals in segments of the second control channel intended for said mobile node, and to detect a period of reduced control signaling to said mobile node on said second control channel;

17. The device of claim 16, wherein transitioning from said second state of operation to the third state of operation includes ceasing to monitor said second control channel.
18. The device of claim 17, wherein said means for monitoring said first control channel during said first state of operation includes circuitry for monitoring said first control channel on a continuous basis.
19. The device of claim 18, wherein said second control channel is a non-continuous control channel including at least some control segments dedicated to said mobile node.
20. A communications system comprising:
a plurality of mobile nodes, each of the plurality of mobile nodes being capable of operating in one of a plurality of states;

a base station for transmitting signals to said plurality of mobile nodes, over first and second control channels; and where at least one of said plurlality of mobile nodes includes:
i) means for monitoring, during a first state of operation, a first control channel to detect control signals in segments of the first control channel intended for said mobile node, and to detect a period of reduced control signaling to said mobile node on said first control channel; and ii) means for transitioning from said first state of operation to a second state of operation in response to detecting a period of reduced control signal signaling to said mobile node on said first control channel, wherein transitioning from said first state of operation to the second state of operation includes ceasing to monitor said first control channel.
