Method and apparatus for reducing power consumption in a selective call radio
First Claim
1. A method used within a selective call radio for substantially reducing power consumption of the selective call radio while the selective call radio is in an inactivated state, wherein the selective call radio is for receiving digital signals having a periodic protocol, and wherein said digital signals are transmitted by radio signals in a radio system, said method comprising the steps of:
- storing a selective call address within the selective call radio;
setting an activation mode of the selective call radio to the inactivated state during which a power state of the selective call radio is cycled at an inactivated duty cycle, and during which a first selective call message having the selective call address is received and processed; and
setting the activation mode of the selective call radio to an activated state during which the power state of the selective call radio is cycled at an activated duty cycle which is substantially greater than the inactivated duty cycle, in response to an activation command generated during the inactivated state set in said step of setting the activation mode to the inactivated state.

Abstract
A technique substantially reduces power consumption of a selective call radio (106) while the selective call radio (106) is in an inactivated state. During the inactivated state a power state of the selective call radio (106) is cycled at an inactivated duty cycle and a first selective call message having a selective call address of the selective call radio (106) is received and processed. An activation mode of the selective call radio (106) is set to an activated state during which the power state of the selective call radio (106) is cycled at an activated duty cycle. The activated duty cycle is substantially greater than the inactivated duty cycle. The activation mode of the selective call radio is set to the activated state in response to an activation command generated during the inactivated state.

9. A selective call radio within which power consumption is substantially reduced while the selective call radio is in an inactivated state, wherein the selective call radio is for receiving digital signals having a periodic protocol, and wherein said digital signals are transmitted by radio signals in a radio system, said selective call radio comprising:
-
a memory for storing a selective call address within the selective call radio; a receiver section for receiving radio signals; a controller, coupled to said memory and said receiver section, for acquiring synchronization and for decoding and processing selective call messages from the radio signals, said controller further comprising; an activation mode element for setting an activation mode of the selective call radio to one of the inactivated state and an activated state; an inactivated state element, coupled to said activation mode element, for operating the selective call radio in the inactivated state during which a power state of the selective call radio is cycled at an inactivated duty cycle, and during which a first selective call message having the selective call address is received and processed; and an activated state element, coupled to said activation mode element, for operating the selective call radio in the activated state during which the power state of the selective call radio is cycled at an activated duty cycle which is substantially greater than the inactivated duty cycle; and wherein said activation mode element sets the activation mode to the activated state in response to an activation command generated during the inactivated state. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
