displaying the first document presentation in the window.
11. The method of claim 8, further comprising:
accessing the second search result page; and
recording a third location of the second search result page, wherein the recordation of the third location causes the second location of the first search result page to be unrecorded.
12. The method of claim 11, further comprising:
accessing a third document presentation other than the search result via the window;
in response to a second input, without having to select from a menu of document presentations, directly retrieving the second search result page from the recorded third location; and
displaying the second search result page in the window.
13. A method, comprising:
automatically recording a location of a first document presentation when the first document presentation is accessed via certain predetermined methods which includes entering an address into an address field;
accessing at least one second document presentation from the first document presentation; and
in response to an input, without having to select from a menu of document presentations, directly retrieving the first document presentation from the location.
14. The method of claim 13, wherein the certain predetermined methods further includes accessing the first document presentation from a predefined favorite document list.
15. The method of claim 13, further comprising displaying a marker when the at least one second document presentation is accessed, wherein the input is received via an activation of the marker.
16. The method of claim 15, further comprising removing the marker when the first document presentation is retrieved.
17. A method, comprising:
accessing a first document presentation from a first location, the first location being recorded, the first document presentation being displayed within a window;
accessing a second document presentation which is displayed within the window; and
recording a second location of the second document presentation, wherein the recordation of the second location causes the first location to be unrecorded.
18. The method of claim 17, wherein the second location of the second document presentation is recorded when the second document presentation is accessed via typing an address into an address field or via a selection from a bookmark.
19. The method of claim 17, wherein the second location of the second document presentation is recorded in response to a user request.
20. The method of claim 17, further comprising:
accessing a third document presentation originated from the second document presentation; and
in response to an input, without having to select from a menu of document presentations, directly retrieving the second document presentation from the recorded second location.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method of controlling a user station applied in a wireless communication system, said wireless communication system comprises an access point (AP) communicates with the user station, the user station comprises a low power unit for saving power consumption, the method comprising:
entering a power save mode wherein the power save mode comprises a listen phase and a deep sleep phase; and
switching between the listen phase and the deep sleep phase wherein the low power unit listens to a predefined event in the listen phase and idles in the deep sleep phase.
2. The station controlling method according to claim 1, further comprising:
synchronizing the low power unit with the AP automatically.
3. The station controlling method according to claim 1, further comprising:
returning to a normal operational mode when losing a particular packet a plurality of times; and
transmitting a NULL packet and waiting for acknowledgement.
4. The station controlling method according to claim 1, wherein the step of entering the power save mode further comprising:
informing the AP that the user station will enter the power save mode;
setting the user station by a plurality of instructions wherein the plurality of instructions comprises information of at least one of a waited packet type for waking up a host module, a timer for beacon, a PLL turning onoff timing, and a RFBB control sequence; and
switching control of the user station to the low power unit and entering the power save mode.
5. The station controlling method according to claim 3, wherein the step of returning to the normal operational mode further comprising:
asserting a wake up event to wake up a host module if a wanted event is received; and
switching control of the user station to the host module and returning to the normal operational mode.
6. The station controlling method according to claim 4, wherein the step of switching the control of the user station further comprises setting a low power switch register of the user station to switch the control of the user station.
7. The station controlling method according to claim 5, wherein a pattern of the wanted event can be programmed by the host module.
8. The station controlling method according to claim 1, wherein the wireless communication specification between the AP and the user station is IEEE 802.11.
9. The station controlling method according to claim 1, wherein the step of switching between the listen phase and the deep sleep phase further comprises:
transmitting and receiving packets in the listen phase and idling to save power in the deep sleep phase;
transmitting a NULL packet and waiting for acknowledgement while losing packet a plurality of times for basic connection; and
counting a predetermined wakeup time to switch between the listen phase and the deep sleep phase.
10. The station controlling method according to claim 1, wherein a low power switch register of the user station can be reset to directly leave the power save mode and return to a normal operational mode.
11. The station controlling method according to claim 1, wherein a normal operational clock is chosen as an operational clock of the low power unit in the listen phase and a slow operational clock is chosen as the operational clock of the low power unit in the deep sleep phase.
12. The station controlling method according to claim 1, wherein the predefined event includes at least one of a wanted beacon and a wanted packet.
13. The station controlling method according to claim 2, wherein the step of synchronizing includes synchronizing the low power unit with the AP automatically when receiving a particular packet.
