A system for a wireless mobile station is disclosed. The system enables the mobile station to adaptively adjust sleep durations and wakeups during a low power idle mode between paging channel slots. The adjustment of sleep durations and wakeups are based on number of key-presses or other input/output (I/O) activities within a fixed number of paging channel slots. The adjustment increases standby time for the mobile station.

1. A method of increasing standby time in a wireless mobile station, comprising:operating in a first state wherein the mobile station enters a sleep state for a first number of periods between consecutive assigned slots;determining whether likelihood of requiring a response to an event is diminished

1. A method of increasing standby time in a wireless mobile station, comprising:operating in a first state wherein the mobile station enters a sleep state for a first number of periods between consecutive assigned slots;determining whether likelihood of requiring a response to an event is diminished while operating in the first state;transitioning to a second state when the likelihood is diminished; andoperating in said second state wherein the mobile station enters the sleep state for a second number of periods between consecutive assigned slots, wherein said second number of periods corresponding to operating in said second state is less than said first number of periods corresponding to operating in said first state. 2. The method of claim 1, wherein the periods of said first state have a first duration and the periods of said second state have a second duration that is longer than said first duration. 3. The method of claim 2, wherein said first duration and second duration are fixed. 4. The method of claim 1, wherein said measure of likelihood is one of the group consisting of the time since a last key press, a time since a date connection, a time since input/output activity, and a number of key presses during a time period. 5. The method of claim 1, further comprising comparing said measure of likelihood to a threshold to determine whether or not to transition from said first state to said second state. 6. The method of claim 2, wherein response to an event occurs after completing any period in progress. 7. A method of increasing standby time in a wireless mobile station that operates in at least one of a first state and a second state, comprising:operating in said second state by entering a sleep state for a second number of periods between consecutive assigned slots;determining whether likelihood of requiring a response to an event is increased while operating in the second state;transitioning to said first state when the likelihood is increased; andoperating in said first state by entering the sleep state for a first number of periods between consecutive assigned slots, wherein said second number of periods corresponding to operating in said second state is less than said first number of periods corresponding to operating in said first state. 8. The method of claim 7, wherein the periods of said first state have a first duration and the periods of said second state have a second duration that is longer than said first duration. 9. The method of claim 8, wherein said first duration and said second duration are fixed. 10. The method of claim 7, wherein said measure of likelihood is one of the group consisting of the time since a last key press, a time since a data connection, a time since input/output activity, and a number of key press during a time period. 11. The method of claim 7, further comprising comparing said measure of likelihood to a threshold to determine whether or not to transition from said second state to said first state. 12. The method of claim 7, wherein response to an event occurs after completing any period in progress. 13. A sleep system for a wireless mobile station, comprising:a circuit that enables a wireless mobile station to operate in one of a first state and a second state during low power idle operation whereinthe wireless mobile station enters a sleep state during separate short sleep periods and wakes during an intermediate wake up period between consecutively assigned slots in the first state,the wireless mobile station enters the sleep state during a long sleep period between the consecutive assigned slots in the second state, the long sleep period is longer than the short sleep period,the circuit determines whether likelihood of requiring a response to an event is diminished, andthe circuit controls the state of the wireless mobile station based on the likelihood so that the wireless mobile station transitions from the first state to the second state when the likelihood is diminished while operating in the first state. 14. The system of claim 13, wherein said circuit further includes a timer that provides an amount of time the mobile station has been in the first state. 15. The system of claim 14, wherein said circuit further includes an expiration time register that holds an expiration time for said timer, said expiration time indicating when to transition from the first state to the second state. 16. The system of claim 14, wherein said circuit further includes a processor operating to reset said timer based on a number of key presses or other input/output (I/O) activities within a period of time. 17. The system of claim 14, wherein duration of said sleep periods is fixed for each state and wherein a response to an event occurs after completing any sleep period in progress. 18. The method of claim 1, wherein the diminishment of the likelihood is determined by determining whether a certain time period has lapsed without receiving an input. 19. The method of claim 1, further composing:determining whether the likelihood is increased within the second state;transitioning from the second state to the first state when the likelihood is increased; andoperating in the first state. 20. The method of claim 19, wherein the increase of the likelihood is determined by determining whether an input is received. 21. The method of claim 1, wherein the mobile station exits the sleep state for a first number of intermediate wakeups that are provided between the consecutive periods in the first state,the mobile station exits the sleep state for a second number of intermediate wakeups that are provided between the consecutive periods in the second state, andthe second number of intermediate wakeups corresponding to operating in said second state is less than said first number of intermediate wakeups corresponding to operating in said first state. 22. The method of claim 9, wherein the mobile station exit the sleep state for a first number of intermediate wakeups that are provided between the consecutive periods in the first state,the mobile station exits the sleep state for a second number of intermediate wakeups that are provided between the consecutive periods in the second state, andthe second number of intermediate wakeups corresponding to operating in said second state is less than said first number of intermediate wakeups corresponding to operating in said first state.
