Power saving arrangement and method in portable cellular telephone system
First Claim
1. In a system having a base station operative for transmitting messages having repeated words to portable, battery-operated, mobile stations, each having on-board electronic means including receiver means operative for receiving the transmitted messages in a stand-by mode, a power-conserving arrangement for minimizing battery power consumption at one mobile station during the stand-by mode, said arrangement comprising:
- (a) detector means for detecting that a transmitted message received by the receiver means at said one mobile station is intended for another station in a non-calling state, said detector means including a programmed microprocessor at said one mobile station, said microprocessor having means for determining a time period between successive messages, said time period being a function of the number of words that have been repeated and the number of additional different words to come; and
(b) power-conserving means responsive to detection of the non-calling state, for reducing battery power to at least one of the electronic means at said one mobile station, and for maintaining the battery power reduction throughout said time period.

Abstract
Battery power consumption of a cellular telephone is minimized during the stand-by mode by detecting when a received message is intended for another telephone, and for reducing battery power to at least one of the electronic components at the telephone when the transmitted message is intended for another telephone. Power is restored when the next transmitted message is expected to be received by the telephone.

14. In a cellular telephone system operative for transmitting messages having repeated words to portable, battery-operated, mobile cellular telephones, each having on-board electronic means including receiver means operative for receiving the transmitted messages in a stand-by mode, a power-conserving arrangement for minimizing battery power consumption at one cellular telephone during the stand-by mode, said arrangement comprising:
-
(a) detector means for detecting that a transmitted message received by the receiver means at said one cellular telephone is intended for another cellular telephone in a non-calling state, said detector means including a programmed microprocessor at said one cellular telephone, said microprocessor having means for determining a time period between successive messages, said time period being a function of the number of words that have been repeated and the number of additional different words to come; and (b) power-conserving means responsive to detection of the non-calling state, for reducing battery power to at least one of the electronic means at said one cellular telephone, and for maintaining the battery power reduction throughout said time period.

15. In a system having a base station operative for transmitting messages having repeated words to portable, battery-operated, mobile stations, each having on-board electronic means including receiver means operative for receiving the transmitted messages in a stand-by mode, a method for minimizing battery power consumption at one mobile station during the stand-by mode, said method comprising the steps of:
-
(a) detecting that a transmitted message received by the receiver means at said one mobile station is intended for another station in a non-calling state, said detecting step including determining a time period between successive messages, which time period is a function of the number of words that have been repeated and the number of additional words to come; and (b) reducing battery power to at least one of the electronic means at said one mobile station in response to detection of the non-calling state, and maintaining the battery power reduction throughout said time period.
