Abstract
Abstract A method and device are provided for controlling an activity mode of a mobile station after the system has originated or terminated a transaction with the mobile station. The activity mode corresponds to whether the mobile station stays "awake" or goes into a sleep mode, which must be made known to the system. If the mobile station does not immediately go to the sleep mode, the base station can expect the mobile station to be reading all slots. If the mobile station is in the sleep mode, the mobile station only reads its assigned paging slots. The mobile station may not go to the sleep mode until a selected amount of activity time has expired; during the activity time, the mobile station continues to read all slots. As a result, the mobile station can immediately receive packets, thereby saving set-up time which increases the response time of the mobile station.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
115 words
A method for controlling readiness levels including an awake mode and a sleep mode of a mobile station in a wireless communication system, comprising the steps of: (a) changing the readiness level in which the mobile station is operating from a first readiness level to a second readiness level in response to the expiration of at least one timer having a period which is variable substantially independent of communication system operation requirements; and (b) determining, at the system, the readiness level of the mobile station, wherein the mobile station reads substantially all time slots for a first predetermined time during said awake mode and the mobile station reads assigned paging slots during said sleep mode.
Claim 2
Independent Claim
115 words
A method for controlling readiness levels including an awake mode and a sleep mode of a mobile station in a wireless communication system, comprising the steps of: (a) changing the readiness level in which the mobile station is operating from a first readiness level to a second readiness level in response to the expiration of at least one timer having a period which is variable substantially independent of communication system operation requirements; and (b) determining, at the system, the readiness level of the mobile station, wherein the mobile station reads substantially all time slots for a first predetermined time during said awake mode and the mobile station reads assigned paging slots during said sleep mode.
Claim 3
Dependent Claim
32 words
A method according to claim 1, further comprising the step of returning to a digital control channel (DCCH) after said second predetermined time and entering a DCCH sleep mode on said DCCH.
Claim 4
Dependent Claim
21 words
The method of claim 1, wherein the at least one timer has a period selectable by an individual mobile station user.
Claim 5
Independent Claim
129 words
A system for controlling readiness levels including an awake mode and a sleep mode of a mobile station in a wireless communication system, comprising: means for changing the readiness level in which the mobile station is operating from a first readiness level to a second readiness level in response to the expiration of at least one timer having a period which is variable substantially independent of communication system operation requirements; and means for informing the system of the readiness level of the mobile station, wherein the mobile station reads substantially all time slots for a first predetermined time during said awake mode and the mobile station reads assigned paging slots during said sleep mode for a second predetermined time after said first predetermined time of a packet data channel.
Claim 6
Independent Claim
129 words
A system for controlling readiness levels including an awake mode and a sleep mode of a mobile station in a wireless communication system, comprising: means for changing the readiness level in which the mobile station is operating from a first readiness level to a second readiness level in response to the expiration of at least one timer having a period which is variable substantially independent of communication system operation requirements; and means for informing the system of the readiness level of the mobile station, wherein the mobile station reads substantially all time slots for a first predetermined time during said awake mode and the mobile station reads assigned paging slots during said sleep mode for a second predetermined time after said first predetermined time of a packet data channel.
Claim 7
Dependent Claim
31 words
A system according to claim 4, further comprising means for returning to a digital control channel (DCCH) after said second predetermined time and entering a DCCH sleep mode on said DCCH.
Claim 8
Dependent Claim
21 words
The system of claim 4, wherein the at least one timer has a period selectable by an individual mobile station user.
