Methods to reduce power for asynchronous internet message protocols
A method for reducing power consumption in a mobile station is provided. The method includes holding data associated with a first polling message until a first scheduled RF wake-up of the mobile station. The method also includes sending the data associated with the first polling message at substantially the same time as the first scheduled RF wake-up of the mobile station. The method further includes holding a second polling message until a second scheduled RF wake-up of the mobile station. The scheduled RF wake-ups of the mobile station are determined according to a schedule established by a service provider of the wireless communication network. In certain embodiments, the polling messages are associated with an ActiveSync® Ping command.
1. For use in a wireless communication network, a mobile station configured to reduce power consumption, the mobile station comprising:
a battery; and
a controller operatively coupled to the battery, the controller configured to:
hold data associated with a first polling message until a first scheduled RF wake-up of the mobile station;
send the data associated with the first polling message at substantially the same time as the first scheduled RF wake-up of the mobile station;
hold data associated with a second polling message until a second scheduled RF wake-up of the mobile station;
start a timer; and
send data associated with a third polling message before a third scheduled RF wake-up when the timer reaches a predetermined value.
2. The mobile station of claim 1 , wherein the data associated with the first and second polling messages is held in a queue in a radio link control (RLC) layer.
3. The mobile station of claim 1 , the controller further configured to establish a TCP connection to a base station in the wireless communication network at substantially the same time as the first scheduled RF wake-up of the mobile station.
4. The mobile station of claim 1 , wherein the first and second scheduled RF wake-ups of the mobile station are determined according to a schedule established by a service provider of the wireless communication network.
5. The mobile station of claim 1 , the controller further configured to turn off a transceiver of the mobile station during an idle period between the first and second scheduled RF wake-ups of the mobile station.
6. The mobile station of claim 1 , wherein the first and second polling messages are associated with an ActiveSync® Ping command.
7. The mobile station of claim 4 , wherein the data associated with the first and second polling messages is held in a queue in a radio link control (RLC) layer.
8. The mobile station of claim 3 , wherein the controller is configured to establish the TCP connection by placing the mobile station in a Cell_DCH state.
9. For use in a mobile station in a wireless communication network, a controller configured to reduce power consumption by the mobile station, the controller configured to:
hold data associated with a first polling message until a first scheduled RF wake-up of the mobile station;
send the data associated with the first polling message at substantially the same time as the first scheduled RF wake-up of the mobile station;
hold data associated with a second polling message until a second scheduled RF wake-up of the mobile station;
start a timer; and
send data associated with a third polling message before a third scheduled RF wake-up when the timer reaches a predetermined value.
10. The controller of claim 9 , wherein the data associated with the first and second polling messages is held in a queue in a radio link control (RLC) layer.
11. The controller of claim 9 , the controller further configured to establish a TCP connection to a base station in the wireless communication network at substantially the same time as the first scheduled RF wake-up of the mobile station.
12. The controller of claim 9 , wherein the first and second scheduled RF wake-ups of the mobile station are determined according to a schedule established by a service provider of the wireless communication network.
13. The controller of claim 9 , the controller further configured to turn off a transceiver of the mobile station during an idle period between the first and second scheduled RF wake-ups of the mobile station.
14. The controller of claim 9 , wherein the first and second polling messages are associated with an ActiveSync® Ping command.
15. The controller of claim 12 , wherein the data associated with the first and second polling messages is held in a queue in a radio link control (RLC) layer.
16. The controller of claim 11 , wherein the controller is configured to establish the TCP connection by placing the mobile station in a Cell_DCH state.
17. For use in a wireless communication network, a method for reducing power consumption in a mobile station, the method comprising:
holding data associated with a first polling message until a first scheduled RF wake-up of the mobile station;
sending the data associated with the first polling message at substantially the same time as the first scheduled RF wake-up of the mobile station;
holding data associated with a second polling message until a second scheduled RF wake-up of the mobile station;
starting a timer; and
sending data associated with a third polling message before a third scheduled RF wake-up when the timer reaches a predetermined value.
18. The method of claim 17 , wherein the data associated with the first and second polling messages is held in a queue in a radio link control (RLC) layer.
19. The method of claim 17 , further comprising:
establishing a TCP connection to a base station in the wireless communication network at substantially the same time as the first scheduled RF wake-up of the mobile station.
20. The method of claim 17 , wherein the first and second scheduled RF wake-ups of the mobile station are determined according to a schedule established by a service provider of the wireless communication network.
