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 are monitored during different states of operation. A mobile node monitors during a first state 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 control channel, and then, in response to detecting a period of reduced control signal signaling to the mobile node, transitions from said first state to a second state of operation. During the second state of operation fewer control channels are monitored and the first control channel is not monitored.

Claims20

Dependent claims

A device comprising a processor configured to control said device to implement a method of operating a mobile node capable of operating in a plurality of states of operation, the method comprising:

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;
in response to detecting said period of reduced control signaling to said mobile node on said first control channel, transitioning from said first state of operation to a second state of operation, wherein transitioning from said first state of operation to the second state of operation includes ceasing to monitor said first control channel;
and
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 signaling to said mobile node on said second control channel, transitioning from said second state of operation to a third state of operation.
