Fig. 3 performs a radio layer passage retention mechanism C for the Radio Network System 200 shown in Fig. 2
rFthe sequential chart of an embodiment.In this example, suppose that the distance of user side 220_1 and access point 210 is near compared with the distance of user side 220_2 and access point 210, this is only as example, use is described, the restriction of non-invention.As shown in Figure 3, user side 220_1 and the good transmission start time of access point 210 agreement with terminate the delivery time and be respectively t1 and t2.If before time t 1, another user side 220_2 just carries out transfer of data, and this transmission may affect user side 220_1 and use at the passage that the awakening period (aggressive mode or title normal mode, mode of operation, operator scheme) starts to transmit data.Therefore, at this machine-processed C
rFin, access point 210 sets the time t3 that is done sth. in advance reserve channel, and when time t3, enter a radiofrequency signal layer passage retained-mode.In one embodiment, access point 210 is in radiofrequency signal layer passage retained-mode, the through-put power of wireless signal downgraded make to carry out communication with user side 220_1 and the power of communication cannot be carried out with user side 220_2, therefore the communicating interrupt with user side 220_2 can be caused; Another execution mode is the transfer of data of access point 210 forced interruption user side 220_2.Access point 210, when time t2, terminates this radiofrequency signal layer path protection pattern.Radio layer path protection mechanism C is started for user side 220_1 at access point 210
rFand the path protection period of access point 210 when being in radiofrequency signal layer path protection pattern; user side 220_2 or other farther user side all cannot normally transmit; therefore the interference of other user side can be reduced; guarantee the period of user side 220_1 between time t1, t2, have higher probability can obtain the passage right to use and pass harvest merit.
Fig. 4 is that Radio Network System 200 performs medium access control layer (Media Access Control, MAC) path protection mechanism C
mACthe sequential chart of an embodiment.As shown in Figure 4, user side 220_1 and the good transmission start time of access point 210 agreement with terminate the delivery time and be respectively t1 and t2.At medium access control layer path protection mechanism C
mACin, access point 210 sets the time t4 that is done sth. in advance protection channel, and enters a medium access control layer path protection pattern by a normal mode when time t4.In medium access control layer path protection pattern; access point 210 performs the packet receiving and transmission program (frame exchange sequence) that passage retains (channelreservation); thus by network configuration vector (Net Allocation Vector; NAY) or other be applied to the mechanism of medium access control layer; guarantee that reserve channel is to the user side 220_1 being about to start to transmit in medium access control layer; guarantee the period of user side 220_1 at time t1 to time t2, to obtain the passage right to use and to pass harvest merit.Access point 210 terminates this medium access control layer path protection pattern when time t2.
In medium access control layer path protection pattern; access point 210 transmits particular packet (such as: empty data (NULL data) package NULL or request transmission (request to send; RTS) package RTS, etc. package) to user side 220_1 ~ 220_n; wherein duration (duration) field record of the shelves head (header) of particular packet be time t4 to time t2, and in particular packet, specified receiver address is the medium access control layer address of user side 220_1.After user side 220_2 ~ 220_n receives particular packet, the duration of recording in particular packet (that is t4 ~ t2) is logged in respective network configuration vector, and within this period, do not send any package to access point 210.Thus, can guarantee that user side 220_1 can obtain the passage right to use in the period of time t1 to time t2 and pass harvest merit.
Fig. 5 is medium access control layer path protection mechanism C
mACthe sequential chart of the first embodiment.As shown in Figure 5, this particular packet is empty data (NULL data) package NULL.
Fig. 6 is medium access control layer path protection mechanism C
mACthe sequential chart of the second embodiment.As shown in Figure 6, this particular packet is request transmission (request to send, RTS) package RTS.
Fig. 7 is medium access control layer path protection mechanism C
mACthe sequential chart of the 3rd embodiment.In medium access control layer path protection pattern; access point 210 transmits an interference package JP to user side 220_1 ~ 220_n; length (length) field in the shelves head (header) of wherein package JP is can period of guard time t4 to time t2, and the receiver address specified by package JP is the medium access control layer address of user side 220_1.During time t4 to time t2, no matter whether user side 220_2 ~ 220_n can pick out package JP is an interference package, this user side 220_2 ~ 220_n all must receive the length specified by package JP, but it is an interference package (jammingpacket) that user side 220_1 picks out package JP, and the receiver address specified by package JP is user side 220_1, therefore in period of time t4 to time t2, user side 220_1 normally can transmit with access point 210, and user side 220_2 ~ 220_n can not attempt transmitting package.Thus, the period of user side 220_1 at time t1 to time t2 can be guaranteed, the passage right to use can be obtained and pass harvest merit.
Fig. 8 is medium access control layer path protection mechanism C
mACthe sequential chart of the 4th embodiment.In medium access control layer path protection pattern, access point 210 utilizes the mechanism of carrying (Piggyback) secretly.This mechanism is: the right to use first being grabbed channel C H1 by access point 210, therefore user side all cannot get the right to use of channel C H1 during medium access control layer path protection pattern.Access point 210 transmits the first stroke package P1 to user side 220_1 by channel C H1, when allowing user side 220_1 by replying a confirmation (ACK) package, carries at least one data packet in the lump secretly.Thus, the period of user side 220_1 at time t1 to time t2 can be guaranteed, the passage right to use can be obtained and pass harvest merit.
Note that above-described embodiment is only illustrate for example, not restriction of the present invention.Such as: two kinds of above-mentioned mechanism, can use simultaneously, also can according to different conditions, independent use.
Please refer to Fig. 9, Fig. 9 is the flow chart of an embodiment of passage collocation method of the present invention.Step in flow chart shown in Fig. 9 not necessarily performs continuously in accordance with this sequence, that is other step also can be inserted wherein.The operation of passage collocation method can be summarized as follows:
Step 902: the very first time that in agreement and user side 220_1 ~ 220_n, a targeted customer holds (such as user side 220_1) to start to carry out transmitting and the second time terminating to transmit, wherein this second time is later than this very first time.
Step 904: perform within the 3rd time to this second time to should targeted customer end (such as user side 220_1) path protection mechanism (such as radio layer path protection mechanism C
rFand/or medium access control layer path protection mechanism C
mAC), wherein the 3rd time is early than this very first time.
Persond having ordinary knowledge in the technical field of the present invention can understand the operation of each step in Fig. 9 easily after reading above-described embodiment, therefore does not repeat in addition.
The foregoing is only preferred embodiment of the present invention, all equalizations done according to the claims in the present invention scope change and modify, and all should belong to covering scope of the present invention.
