Embodiment
See also Fig. 1, be depicted as the module map of the mobile radio station 200 in the embodiment of the present invention.
Mobile radio station 200 communicates to connect with base station 100, and (Institute of Electrical and Electronic Engineers, 802.11 standards of IEEE) being formulated communicate by Institute of Electrical and Electronics Engineers IEEE between the two.
Mobile radio station 200 has true address and virtual address, and above-mentioned address is media interviews control (Media Access Control, MAC) address.Mobile radio station 200 comprises link block 202, mode switch module 204, authentication module 206 and logging modle 208.
Link block 202 is used for by true address and virtual address and base station 100 connect respectively (Association).In the present embodiment, link block 202 connects by IEEE 802.11 standards.
Mode switch module 204 is used for handover of mobile stations 200 and is in activity pattern or battery saving mode.In the present embodiment, mode switch module 204 true address by mobile radio station 200 sends request to base station 100 and sends that (Request to Send, RTS) frame or Null frame come handover of mobile stations 200 to be in activity pattern or battery saving mode.This request transmit frame and Null frame comprise that all (wherein, if mobile radio station 200 requests enter activity pattern from battery saving mode, the value of then asking the power saving bit field of transmit frame or Null frame is 0 to province's current potential for Power Save Bit, PSB) field; If mobile radio station 200 requests enter battery saving mode from activity pattern, the value of then asking the power saving bit field of transmit frame or Null frame is 1.
Authentication module 206 is used for sending test frame by virtual address to base station 100, sends data to base station 100 then and obtains frame, and set the scheduled time of obtaining this test frame.
In the present embodiment, when link block 202 with after base station 100 is connected, authentication module 206 can send test frame to base station 100 by virtual address, the destination address of this test frame is the true address of mobile radio station 200.It is that (this power-save poll frame sends after activity pattern enters battery saving mode in mobile radio station 200 requests power-save poll for Power Save Poll, PS-Poll) frame that these data are obtained frame.This scheduled time equals to be issued to data from test frame and obtains the time period that frame sends, and this scheduled time is made as 5 milliseconds in the present embodiment.
Authentication module 206 is used to also judge that whether the time that receives this test frame is greater than this scheduled time.In the present embodiment, if greater than this scheduled time, illustrate that base station 100 supports that carrying out battery saving mode by the frame turnaround sequence switches; If be less than or equal to this scheduled time, illustrate that base station 100 do not support that carrying out battery saving mode by the frame turnaround sequence switches.
Know clearly it, when mode switch module 204 request when activity pattern enters battery saving mode, then authentication module 206 need obtain frame to base station 100 transmission data and obtain this test frame, if base station 100 supports that carrying out battery saving mode by the frame turnaround sequence switches, then base station 100 is transmitted to the true address of mobile radio station 200 with this test frame after data are obtained frame receiving.If base station 100 does not support that carrying out battery saving mode by the frame turnaround sequence switches, then base station 100 is transmitted to the true address of mobile radio station 200 with this test frame before obtaining frame receiving data.
Authentication module 206 is used to also judge whether mobile radio station 200 receives the test frame that it sends by virtual address.In the present embodiment, authentication module 206 enters activity pattern in mobile radio station 200 request from battery saving mode, and test frame just begins to judge whether to receive this test frame after sending.
Know clearly it, when mode switch module 204 request when battery saving mode enters activity pattern, if base station 100 allows it to switch, then after this test frame sends to base station 100, base station 100 is forwarded to this test frame the true address of mobile radio station 200, illustrate that (Frame Exchange Sequence FES) carries out battery saving mode and switches by the frame turnaround sequence in base station 100 supports this moment.If base station 100 does not support that carrying out battery saving mode by the frame turnaround sequence switches, then after this test frame sent to base station 100, base station 100 can not be forwarded to this test frame the true address of mobile radio station 200.
Logging modle 208 is used to write down base station 100 and whether supports that carrying out battery saving mode by the frame turnaround sequence switches.In present embodiment, the result of logging modle 208 record comprise base station 100 support by the frame turnaround sequence from the activity pattern to the battery saving mode, switches, base station 100 do not support by the frame turnaround sequence from the activity pattern to the battery saving mode, switches, base station 100 supports pass through the switching of frame turnaround sequence from the battery saving mode to the activity pattern, and base station 100 is not supported by the switching of frame turnaround sequence from the battery saving mode to the activity pattern.Particularly, logging modle 208 time that authentication module 206 receives test frame during greater than the scheduled time record base station 100 support from the activity pattern to the battery saving mode, to switch by the frame turnaround sequence, record base station 100 is not supported to switch from the activity pattern to the battery saving mode by the frame turnaround sequence when the time that authentication module 206 receives test frame is not more than the scheduled time.Logging modle 208 writes down base station 100 and supports to switch from the battery saving mode to the activity pattern by the frame turnaround sequence when authentication module 206 receives test frame, record base station 100 is not supported to switch from the battery saving mode to the activity pattern by the frame turnaround sequence when authentication module 206 receives test frame.
