When application program is stream, buffer (storage part 14) size of 30 investigation base stations 10, terminal radio station, data speed that reproduces from stream and buffer size calculated data reproduce the non-destructive long letter mark signal period, the change that base station 10 was required to the beacon signal cycle of obtaining.In view of the above, terminal radio station 30 can carry out receiving intermittence with the non-destructive cycle of data.Therefore, terminal radio station 30, disconnected supplying with from the electric power of 43 pairs of telecommunication circuits 40 of power supply unit before receiving beacon signal by the receiving cycle optimization of the beacon signal of oneself, can suppress to flow the power consumption in reproducing.
Particularly, if at first if the application program (S11) that flows is started by application program execution portion 34, communication interface part 35 just obtain convection current application setting reproduction data speed (for example 480Kbps) (S14), and, base station 10 is required the notice (S19) of available cache memory device size to the starting of end side wireless communication part 36 notification streams application programs.
In addition, the data speed of reproduction can preestablish by each application program in communication interface part 35, also can produce setting in case of necessity, from 34 pairs of communication interface part of application program execution portion, 35 notices.
In end side wireless communication part 36, if receive that from APD 33 the streaming application starting is notified and the notice request (S32) of the buffer size of base station 10, just in beacon signal, comprise the notice request of buffer size, base station 10 is sent.
In the base station 10, if receive the notice request (S66) of buffer size from terminal radio station 30, communication control unit 15 is just obtained the available cache memory device size (for example 30Kbyte) of storage part 14, and it is included in the beacon signal, sends to terminal radio station 30 (S67).
Then, in terminal radio station 30, if 10 receive available cache memory device size (S37～S39, S20) from the base station, communication interface part 35 is just reproduced the longest non-destructive beacon signal cycle (S21) from data speed (for example 480Kbps) and available cache memory device size (for example 30Kbyte) calculated data that stream reproduces.During this example,, become 240/480=500msec from 30Kbyte=240Kbit.35 pairs of end side wireless communication parts of communication interface part 36 require the beacon signal cycle of base station 10 is set at beacon signal cycle (for example Tr=500msec) of obtaining (S22) then.
Beacon signal periodic change when the later processing and the application program of mail is handled same, so omit explanation.
In addition, when application program is stream, if the user selects other flow datas, the situation of the beacon signal that just changes period T r.
In the present example, by the available cache memory device size of 30 reception base stations 10, terminal radio station, the beacon signal cycle of calculating optimum, but can carry out the computing in beacon signal cycle with base station 10.At this moment, the data speed of 30 pairs of base stations, terminal radio station, 10 notification streams reproduction.
In addition, Figure 11 appends at which to send the signal that is used for data communication constantly in the sequence in change beacon signal cycle.Promptly as shown in figure 11, when in base station 10, having flow data (in " data that storage is arranged in the storage part "), send the data of stream with the signal that is used for data communication of following beacon signal.By beacon signal, can notify should be from the base station the having or not of 10 flow datas that send to terminal radio station 30.
In addition, shown in power connection interval among Figure 11 (oblique line portion), terminal radio station 30 is in before changing beacon signal time of reception, on one side the power connection/disconnection of telecommunication circuit 40, Yi Bian carry out the transmission of the notice request of available cache memory device size, the reception of available cache memory device size, the transmission of the change request in beacon signal cycle.The beacon signal cycle after changing, if become beacon signal time of reception, just the power connection of telecommunication circuit 40, receive beacon signal and flow data from base station 10 after, the action that repeats to make the power supply of telecommunication circuit 40 to disconnect.If 10 signals that send from the base station are received in terminal radio station 30, just before becoming the moment that receives next beacon signal, the electric power of telecommunication circuit 40 is supplied with disconnection.Be terminal radio station 30 when not receiving signal, the power supply of telecommunication circuit 40 is disconnected.
[IP phone]
The 3rd, the control when application program execution portion 34 carries out the application program of IP phone is described.In addition, at first the beacon signal cycle is set at default value (T0=100msec).
Figure 12 is the sequence chart of the action in the beacon signal cycle of expression change application program when being IP phone, and Figure 13 is the sequence chart of it being appended the incoming call action.
When application program was IP phone, terminal radio station 30, sent at interval according to packets of information in conversation waiting beacon signal cycle of biding one's time and being set at 1sec, is set at the value (for example 20msec) of the influence that does not take place to postpone.In view of the above, terminal radio station 30 can carry out sending the reception at intermittence of coupling at interval with packets of information.Therefore, terminal radio station 30, disconnected supplying with from the electric power of 43 pairs of telecommunication circuits 40 of power supply unit before receiving beacon signal by the receiving cycle optimization of the beacon signal of oneself, can suppress the power consumption in the conversation.
Particularly, if if the application program (S11) of application program execution portion 34 starting IP phone at first, communication interface part 35 is just to the starting of end side wireless communication part 36 notice IP telephony applications, requires the beacon signal cycle of base station 10 is set at the receiving check interval (for example Ta=1sec) that the grade of the application setting of IP phone is bide one's time.
In addition, wait the beacon signal cycle when biding one's time and conversing in communication interface part 35, to preestablish by each application program, also can be when requiring the change in beacon signal cycle, from 34 pairs of communication interface part of application program execution portion, 35 notices.
In end side wireless communication part 36, if from APD 33 receive IP phone starting notice and etc. the appointment (S32) in beacon signal cycle of biding one's time, in the beacon signal cycle (for example T=1sec) that just in beacon signal, comprises requirement, base station 10 is sent the requirement of beacon signal periodic change.
In the base station 10, if receive mark signal period change request (S68) from terminal radio station 30, communication control unit 15 just changes to the mark signal period (S69) of appointment.At this moment, communication control unit 15 is in the moment of before changing beacon period, send the notice beacon signal in beacon signal cycle after changing after, begin transmission with the beacon signal in moment in after changing beacon signal cycle.
And,,, receive that beacon signal from base station 10 (behind the S33～S35), disconnects (S43) to telecommunication circuit 40 power supplys just the power connection of telecommunication circuit 40 if become the beacon signal time of reception (before changing) in terminal radio station 30.At this moment, receive the setting that is set at requirement in the beacon signal cycle that comprises in the control part 39 affirmation beacon signals, be set at the receiving cycle (S44) of beacon signal.Promptly since next time beacon signal receiving cycle the 1sec that bides one's time such as become.In addition,, just receive data, pass to APD 33 (S40～S42) if carrying expression has the information of the data of issuing this radio station in beacon signal.
Then, at APD 33, if receive data (S15) from end side wireless communication part 36, application program execution portion 34 just passes through sound or display notification incoming call (S16) with efferent 32.Then, if the user connects phone, become talking state, the change in the beacon signal cycle of just biding one's time with above-mentioned grade in terminal radio station 30 is handled same, the beacon signal period T a (for example 20msec) when changing to conversation.If user's on-hook becomes wait state once more, the beacon signal period T a (for example 1sec) that bides one's time such as just change to.When application program is IP phone, in terminal radio station 30, according to the state of wait/conversation, the change beacon signal cycle.
In addition, Figure 13 appends at which to send the signal that is used for data communication constantly in the sequence in change beacon signal cycle.Promptly as shown in figure 13, when in base station 10, having the voice data of IP phone (" transmissions of data "), send voice data with the then signal that is used for data communication of beacon signal.By beacon signal, can notify should be from the base station the having or not of 10 voice datas that send to terminal radio station 30.
In addition, shown in power connection interval among Figure 13 (oblique line portion), bide one's time waiting, if the beacon signal time of reception of biding one's time such as become, the power supply of telecommunication circuit 40 is just connected in terminal radio station 30, receives the beacon signal from base station 10, when incoming call, after receiving incoming telephone signal, repeat the action that the power supply of telecommunication circuit 40 is disconnected.In addition, in when conversation, if just connect the power supply of telecommunication circuit 40, and after receiving voice data, repeat the action that the power supply of telecommunication circuit 40 is disconnected the beacon signal time of reception when becoming conversation.If 10 signals that send from the base station are received in terminal radio station 30, just before becoming the moment that receives next beacon signal, the electric power of telecommunication circuit 40 is supplied with disconnection.Be terminal radio station 30 when not receiving signal, the power supply of telecommunication circuit 40 is disconnected.
(2) in a terminal radio station 30, utilize a base station 10, when carrying out a plurality of application program, be set at the corresponding beacon signal cycle of application program with shorter beacon signal cycle of needs with terminal radio station 30.When end application, be set at the beacon signal cycle that needs the application program correspondence in the shortest beacon signal cycle in other application programs of carrying out.
Figure 14 represents as application program, when carrying out mail, carries out IP phone, the sequence chart of the action in the beacon signal cycle during change FEFO IP phone.Figure 15 is the program flow diagram of the action of the end side wireless communication part 36 of expression application program when being a plurality of.In addition, Figure 15 is that situation when application program is mail, stream, IP phone is summarized as 1.
Here, with in wireless communication system shown in Figure 21, the 34A of portion is carrying out mail with the application program execution, carries out IP phone with the application program execution 34B of portion, is example during the FEFO IP phone, describes.
Particularly, at first, terminal radio station 30 is by the processing of explanation in (1) [mail], according to the automatic mail receiving check of the mail of the application program execution 34A of portion at interval, sets the beacon signal cycle (for example 60sec) of base station 10.Terminal radio station 30 is by the processing of explanation in (1) [IP phone] then, the receiving check interval (for example Ta=1sec) when requiring that the beacon signal cycle of base station 10 is set at the wait state of IP phone of the application program execution 34B of portion.
At this moment, if end side wireless communication part 36 from APD 33 receive IP phone starting notice and etc. the appointment (S72) of the beacon signal of biding one's time, just judge that whether the beacon signal cycle (for example Ta=1sec) that requires is than present beacon signal cycle (for example T=60sec) short (S89), short if (YES), in the beacon signal cycle (for example T=1sec) that just in beacon signal, comprises requirement, base station 10 is sent the beacon signal periodic change require (S90).
And, the beacon signal cycle under the talking state of IP phone (for example 20msec) is shorter than the beacon signal cycle (for example 60sec) of mail, so terminal radio station 30 is by the processing of explanation in (1) [IP phone], by with corresponding beacon signal cycle of wait/talking state of the IP phone of the application program execution 34B of portion, change the beacon signal cycle on one side, Yi Bian carry out the communication of the IP phone of the mail of the application program execution 34A of portion and the application program execution 34B of portion.
Then, if user's End IP telephony application, communication interface part 35 just judges whether carrying out other application programs (S91), if carrying out other application programs (YES), just make beacon signal cycle (T=60sec of mail in the present example) that 36 pairs of base stations of end side wireless communication part 10 require to change to this application program (S92).And, just make 36 pairs of base stations of end side wireless communication part 10 require to change to the default beacon signal cycle (for example T0=100sec) if not carrying out other application programs (NO).
As mentioned above, according to described wireless communication system 1, in a terminal radio station 30, utilize a base station 10, when carrying out a plurality of application program with terminal radio station 30, terminal radio station 30 is passed through the receiving cycle optimization of the beacon signal of oneself, before the moment that receives beacon signal, disconnect supplying with from the electric power of 43 pairs of telecommunication circuits 40 of power supply unit, can suppress power consumption.
In addition, in the present example, the situation when application program is 2 is described, but 3 when above, when finishing an application program, judge whether other application programs start.Therefore, communication interface part 35 can keep managing the table (not shown) of the correspondence in the beacon signal cycle that application program in the starting and this application program require.In view of the above, communication interface part 35 is known the application program in beacon signal cycle that need be the shortest, can set the beacon signal cycle corresponding with it.In addition, in the present example, 30 carry out the judgement in the shortest beacon signal cycle in the terminal radio station, but also can be in the base station 10 carry out this judgement.At this moment, the application program of starting in terminal radio station 30 is notified the beacon signal cycle that requires respectively to base station 10.
(3) in a plurality of terminals radio station 30 ... in when utilizing a base station 10, be set at the beacon signal cycle corresponding with the terminal radio station 30 that needs the shorter beacon signal cycle.When end application, in other-end radio station 30 just, be set at the beacon signal cycle corresponding with the terminal radio station 30 that needs the shortest beacon signal cycle at executive utility.
The program flow diagram of the action of the end side wireless communication part 36 that Figure 16 is expression terminal radio station 30 when a plurality of.The program flow diagram of the action of the base station 10 that Figure 17 is expression terminal radio station 30 when a plurality of.In addition, Figure 16, Figure 17 are that situation when application program is mail, stream, IP phone is summarized as 1.
Here, to carry out mail,, be example during the IP phone of FEFO terminal radio station 30B in terminal radio station 30B (Fig. 4) execution IP phone in terminal radio station 30A (Fig. 4), describe.
Particularly, terminal radio station 30A by the processing of explanation in (1) [mail], according to the automatic mail receiving check interval of mail, sets the beacon signal cycle (for example 60sec) of base station 10 by carrying out mail.Then, terminal radio station 30B is by carrying out IP phone, by the processing of explanation in (1) [IP phone], the receiving check interval (for example Ta=1sec) when the application program execution 34B of portion of terminal radio station 30B requires that the beacon signal cycle of base station 10 is set at the wait state of IP phone (S119).
At this moment, in the base station 10, in the beacon signal cycle (S140) in the beacon signal cycle (S139) that communication control unit 15 comparison terminal radio station 30B require and this moment, select the shorter beacon signal cycle (S141).During this example, compare with the beacon signal cycle of mail, beacon signal cycle of the wait state of IP phone is short, so change to the beacon signal cycle under the wait state of IP phone.At this moment, communication control unit 15 is moment in before changing beacon signal cycle sends the beacon signal in notice beacon signal cycle after changing to terminal radio station 30A and 30B after, and beginning is in the transmission of the beacon signal in the moment in after changing beacon signal cycle.
Then, during the IP telephony application FEFO of terminal radio station 30B, the communication interface part 35 of terminal radio station 30B makes 36 pairs of base stations of end side wireless communication part 10 send the end (S120) of IP telephony application.
At this moment, in the base station 10, communication control unit 15 is judged the IP telephony application that finishes except at terminal radio station 30B, and application program is in work (S142).If the result who judges has other application programs (YES), just in the terminal radio station 30 in communication, change to the shortest beacon signal cycle (S143) in beacon signal cycle.In the present example, change to the beacon signal cycle (Tb=60sec) of the mail of working among the 30A of terminal radio station.
From as can be known above, according to described wireless communication system, when in a plurality of terminals radio station 30 ... in when utilizing a base station 10, by the receiving cycle optimization of beacon signal, before the moment that receives beacon signal, disconnect supplying with from the electric power of 43 pairs of telecommunication circuits 40 of power supply unit, can suppress power consumption.
In addition, in the present example, the situation when terminal radio station 30 is 2 is described, but 3 when above, when end notification is received from a terminal radio station 30 in base station 10, judge and whether communicate by letter with other-end radio station 30.Therefore, communication control unit 15 can keep the table (not shown) of the correspondence in the beacon signal cycle that terminal radio station 30 in the supervisory communications and this terminal radio station 30 require.In view of the above, communication control unit 15 is known the terminal radio station 30 in beacon signal cycle that need be the shortest, can set the beacon signal cycle corresponding with it.
In addition, Figure 18 is the program flow diagram of the action of the end side wireless communication part 36 of expression a plurality of terminals radio station 30 when carrying out a plurality of application program.At this moment,, just base station 10 is sent the shortest beacon signal cycle,, just base station 10 is sent end notification if there is not the application program in the starting if there is the application program of working in communication interface part 35 in this radio station.
The program flow diagram of the action of expression base station 10 at this moment is identical with Figure 17.
Then, terminal radio station 30 be described, replace the beacon signal cycle, the situation when sending the information (beacon signal cycle decision information (the transmission cycle determines information)) that base station 10 is used to determine the beacon signal cycle to base station 10 with reference to Figure 22～Figure 25.
Here, as mentioned above, " communication characteristic " is the kind that becomes the instrument in terminal radio station according to the state of the communication pattern of (a) application program, (b) application program, (c), (d) combination (a)～(c) etc., decision.And, in wireless communication system 1, " communication characteristic " and " kind of application program " utilized as the information that is used to determine the beacon signal cycle " beacon signal cycle decision information ".

[embodiment 2]
If it is, other embodiments of the invention are described, then as described below with reference to Fig. 1～Fig. 4, Figure 19～Figure 21.In addition, for convenience of explanation, for the member of member identical function of expression in described embodiment 1, pay identical symbol, omit explanation.
In the wireless communication system 1 of present embodiment, the kind and/or the communication characteristic (communication pattern of application program and state) of the application program of carrying out according to terminal radio station 30, dynamically the beacon signal receiving cycle of change oneself.The point in beacon signal cycle that does not promptly change base station 10 is different with embodiment 1.In addition, the summary of wireless communication system 1 and detailed structure and Fig. 1～Fig. 4 are same.
Particularly, in the wireless communication system 1 of present embodiment, end side wireless communication part 36 (receiving cycle set parts) is set at the multiple that base station 10 sends the transmission cycle of beacon signal to the receiving cycle that receives beacon signal.In addition, communication interface part 35 (Communications Interface Assembly) the receiving cycle of the beacon signal corresponding with the application program kind carried out and/or communication characteristic in the application program execution portion 34 to end side wireless communication part 36 notices.For example communication interface part 35 obtains the state of the application program of carrying out in the application program execution portion 34, according to this state, and the receiving cycle of decision beacon signal.In addition, the size of the buffer that communication interface part 35 has according to base station 10, the receiving cycle of decision beacon signal.In addition, when communication interface part 35 is carried out a plurality of application program in a terminal radio station 30, the application program in the shortest cycle as required, the receiving cycle of decision beacon signal.
Situation during below with (1)～(2) is an example, and the control in beacon signal cycle of the wireless communication system 1 of present embodiment is described.
(1) with the processing change beacon signal receiving cycle that has only terminal radio station 30.The beacon signal receiving cycle is the multiple in the beacon signal cycle of base station 10.
In addition, base station 10 can send identical beacon signal at the signal (ACK) of receiving confirmation of receipt from terminal radio station 30 before.At this moment, base station 10 repeatedly sends the beacon signal of identical content in the beacon signal in terminal radio station 30 during the cycle., base station 10 is in order to limit the beacon signal that sends identical content once more, the multiple capping in the beacon signal cycle that terminal radio station 30 is set.
Figure 19 is the program flow diagram of the action of expression end side wireless communication part 36.In addition, Figure 19 is that situation when application program is mail, stream, IP phone is summarized as 1.
Here, with in the network configuration of Fig. 4, carrying out mail at terminal radio station 30A, is example when terminal radio station 30B carries out stream, describes.At terminal radio station 30A, the beacon signal that communication interface part 35 is set at base station 10 to the beacon signal receiving cycle sends the 60sec of the integral multiple of cycle 100msec.At terminal radio station 30B, the beacon signal that communication interface part 35 is set at base station 10 to the beacon signal receiving cycle sends the 500msec of the integral multiple of cycle 100msec.In addition, the beacon signal receiving cycle in each terminal radio station is not to base station 10 or other-end radio station 30 notices.
Particularly, at first in the 30A of terminal radio station, if the application program of application program execution portion 34 starting mails, communication interface part 35 is just to end side wireless communication part 36 circular mail application programs startings, requires the beacon signal receiving cycle is set at the automatic mail receiving check of the application setting of mail (for example 60sec) at interval.
At this moment, in communication interface part 35, if the automatic mail receiving check of mail at interval different with present beacon signal receiving cycle (S197), then following such beacon signal receiving cycle of changing of determining to require.Judge that promptly whether the beacon signal receiving cycle be suitable for application program is the default beacon signal period T of base station 10 more than 0, and be that (S198's integral multiple S200), if satisfy condition, remains untouched as beacon signal receiving cycle (S201).For example, default beacon signal period T 0 is 100msec, if the beacon signal receiving cycle is Tr=60sec, and just change on request.And the beacon signal receiving cycle that is suitable for application program is than default value in short-term, do not change (S198, NO).In addition, (for example 60.01sec) when the beacon signal receiving cycle that is suitable for application program is not the integral multiple of default value (S200 NO), is set in the integral multiple of default value recently and is no more than the value of the value of requirement.
And end side wireless communication part 36 is set at the beacon signal receiving cycle according to the requirement from communication interface part 35.Then, if end side wireless communication part 36 becomes beacon signal time of reception, just the power connection of telecommunication circuit 40, receive beacon signal from base station 10 after, the power supply of telecommunication circuit 40 is disconnected.At this moment,, just receive data, pass to APD 33 (S190～192) if in beacon signal, carrying the information that expression has the data of issuing this radio station.
If the user finishes mail (S196), communication interface part 35 just sends to end side wireless communication part 36 to the application program end notification, and the beacon signal receiving cycle returns to default value (before the starting mail) (S199).In addition, when application program is mail, set, just produce the situation that changes beacon signal period T r if the user changes automatic mail receiving check interlude.
Then in the 30B of terminal radio station, if the application program of application program execution portion 34 starting streams, communication interface part 35 just obtains the data speed (for example 480Kbps) of reproduction of the application setting of convection current, and, base station 10 is required the notice (S195) of available cache memory device size to the starting of end side wireless communication part 36 notification streams application programs.If end side wireless communication part 36 10 is received available cache memory device size (S188) from the base station, data speed (for example 480Kbps) and available cache memory device size (for example 30Kbyte) that communication interface part 35 is just reproduced from stream, calculated data reproduces the longest non-destructive beacon signal receiving cycle.When this example, become 240/480=500msec from 30Kbyte=240Kbit.And 35 pairs of end side wireless communication parts of communication interface part 36 require the beacon signal receiving cycle is set at the value (for example Tr=500msec) that obtains (S197).
At this moment, in communication interface part 35, the beacon signal receiving cycle different with present beacon signal receiving cycle if (S197) that calculates, then as mentioned above, be set in the integral multiple of default value recently and be no more than the value (S198, S200, S201, S202) of the beacon signal receiving cycle of calculating.For example the beacon signal receiving cycle of Ji Suaning does not change than default value in short-term.In addition, the beacon signal receiving cycle of calculating is that 512msec is such, when not being the integral multiple of default value, is set in the integral multiple of default value recently and is no more than the value of 512msec.
And end side wireless communication part 36 is set at the beacon signal receiving cycle according to the requirement from communication interface part 35.Then, if end side wireless communication part 36 becomes beacon signal time of reception, just the power connection of telecommunication circuit 40, receive beacon signal from base station 10 after, the power supply of telecommunication circuit 40 is disconnected.At this moment,, just receive data, pass to APD 33 (S190～192) if in beacon signal, carrying the information that expression has the data of issuing this radio station.
If the user finishes stream (S 196), communication interface part 35 just sends to end side wireless communication part 36 to the application program end notification, and the beacon signal receiving cycle returns to default value (before the starting stream) (S199).
In addition, when application program is stream,, just produce the situation that changes beacon signal period T r if the user selects other flow datas.
(2) in a plurality of terminals radio station 30 ... in when utilizing a base station 10, the beacon signal cycle of base station 10 remains untouched, and only changes terminal radio station 30 ... the beacon signal receiving cycle.Terminal radio station 30 ... the beacon signal receiving cycle become the multiple in the beacon signal cycle of base station 10.Difference during with (1) is: 10 each terminal radio station 30 of decision, base station ... the beacon signal receiving cycle, the notice.In addition, the transmission cycle of the beacon signal of base station 10 is certain, so other-end radio station 30 is not exerted an influence.
Figure 20 is the program flow diagram of the action of expression end side wireless communication part 36.Figure 21 is the program flow diagram of the action of expression base station 10.In addition, Figure 20, Figure 21 are that situation when application program is mail, stream, IP phone is summarized as 1.
Here, with in the network configuration of Fig. 4, carrying out mail with terminal radio station 30A, is example when terminal radio station 30B carries out stream, describes.At terminal radio station 30A, the beacon signal that communication interface part 35 is set at base station 10 to the beacon signal receiving cycle sends the 60sec of the integral multiple of cycle 100msec.At terminal radio station 30B, the beacon signal that communication interface part 35 is set at base station 10 to the beacon signal receiving cycle sends the 500msec of the integral multiple of cycle 100msec.
Particularly, at first in the 30A of terminal radio station, if the application program of application program execution portion 34 starting mails, communication interface part 35 is just to end side wireless communication part 36 circular mail application programs startings, and base station side wireless communication part 12 is required the beacon signal receiving cycle is set at the automatic mail receiving check of the application setting of mail (for example 60sec) (S228, S229) at interval.
Then, in the base station 10, if receive the change request (S249) of beacon signal receiving cycle from terminal radio station 30A, communication control unit 15 is just as described in (1), is set in the integral multiple of default value recently and is no more than automatic mail receiving check value (S250) at interval.If for example communication control unit 15 is received change request to beacon signal period T=60sec from terminal radio station 30A, just because the beacon signal cycle that requires be more than the default beacon signal cycle 100msec, and be integral multiple, so the change to beacon signal period T=60sec is sent terminal radio station 30A.In addition, the beacon signal cycle of the beacon signal period ratio default value of change request does not change also in short-term.In addition, the beacon signal cycle of change request resembles the 60.01sec when not being the integral multiple in default beacon signal cycle, is set in the integral multiple in default beacon signal cycle recently and is no more than the 60sec of the value of 60.01sec.
Then base station 10 is at before changing beacon signal delivery time, and next beacon signal period T t=60sec of carrying sends terminal radio station 30A in the beacon signal of issuing terminal radio station 30A.
And in the 30A of terminal radio station, if become the beacon signal time of reception (before changing), just the power connection of telecommunication circuit 40, receive beacon signal from base station 10 and (behind the S213～S216), the power supply of telecommunication circuit 40 is disconnected (S223).At this moment, receive the setting that is set at requirement in the beacon signal cycle that comprises in the control part 39 affirmation beacon signals, be set at the receiving cycle (S224) of beacon signal.Promptly since next time beacon signal receiving cycle become 60sec.In addition,, just receive data, pass to APD 33 (S220～S222) if carrying expression has the information of the data of issuing this radio station in beacon signal.In APD 33, if receive data, just to efferent 32 dateouts from end side wireless communication part 36.
Then, if the user finishes mail (S227), communication interface part 35 just sends the application program end notification to end side wireless communication part 36, and base station 10 is required beacon signal cycle reduction (before the starting mail) (S230).As a result, the beacon signal receiving cycle of terminal radio station 30A returns to 100msec.
In addition, when application program is mail,, just produce the situation that changes the beacon signal cycle if the user changes the time set of free mail reception inspection intervals.
Streaming application among the 30B of terminal radio station is the same, repeats no more.
In addition, in a plurality of terminals radio station 30 ... in when carrying out a plurality of application program, if for example in the A of terminal radio station, need beacon signal cycle 1sec application program ap1, need beacon signal cycle 512msec application program ap2, need the application program ap3 of beacon signal cycle 50msec to start, just select to satisfy the 512msec in beacon signal cycle the shortest more than the 100msec, but the integral multiple of 100msec whether, so the beacon signal receiving cycle of terminal radio station A is set in the integral multiple of 100msec recently and is no more than the 500msec of 512msec.
In addition, also can adopt a plurality of terminals radio station 30 ... the beacon signal receiving cycle of middle decision sends to base station 10, according to 10 beacon signals of receiving from the base station, confirms the structure of beacon signal receiving cycle after changing.In view of the above, in a plurality of terminals radio station 30 ... in when carrying out a plurality of application program, the beacon signal cycle of base station 10 remains untouched, a plurality of terminals radio station 30 ... in, can set best beacon signal receiving cycle.
As mentioned above, in wireless communication system 1 of the present invention, terminal radio station 30 is by the communication pattern and the state of application program according to oneself, the receiving cycle optimization of oneself, thereby can suppress the power consumption in terminal radio station 30.In addition, the communication pattern and the state of the application program of 30 pairs of base stations, terminal radio station 10 notice oneself the transmission cycle optimization of beacon signal, thereby can suppress the power consumption in terminal radio station 30.In addition, in the application programs such as conversation of stream reproduction and IP phone, do not have the influence of data degradation or delay,, can suppress the power consumption in terminal radio station 30 by receiving data off and on.In addition, when carrying out a plurality of application program, or during 30 communications of a plurality of terminals radio station, by the receiving cycle optimization of beacon signal, thereby can suppress the power consumption in terminal radio station 30.
And, in wireless communication system 1 of the present invention, in the terminal radio station 30 of mobile instrument etc., can free power saving ground control terminal side wireless communication part 36.In view of the above, corresponding with the using method of mobile instrument best low power consumption control becomes possibility.
Then on one side with reference to Figure 26～Figure 34, the processing when to describe terminal radio station 30 on one side in detail be a plurality of.If simple declaration, then (1) because from the requirement of certain terminal radio station 30A, and when the beacon signal transmission cycle was shortened in base station 10, other-end radio station 30B changed to the receiving cycle of the beacon signal in this radio station optimal length in the multiple in transmission cycle.(2) base station 10 when the beacon signal transmission cycle is shortened require the time, accept requirement from whole terminals radio station, but the cycle that beacon signal is sent elongated require the time, only accept requirement from the terminal radio station of the requirement of accepting shortening before.In view of the above, the communication in the terminal radio station 30 of carrying out with the short beacon signal transmission cycle is not subjected to the influence in other-end radio station 30.In addition, send the setting in cycle about the beacon signal of base station 10, identical with statement in [embodiment 1], about the setting of the beacon signal receiving cycle of base station 10, identical with statement in [embodiment 2] is so omit detailed explanation.
When terminal radio station 30 has a plurality of, because requirement from certain terminal radio station 30A, when the beacon signal transmission cycle was shortened in base station 10, the beacon signal that other-end radio station 30B changes to base station 10 to the beacon signal receiving cycle in this radio station sent optimal length in the multiple in cycle.In view of the above, even by certain terminal radio station 30A, the beacon signal transmission cycle of base station 10 is shortened, other-end radio station 30B also keeps best beacon signal receiving cycle, can suppress power consumption.
Specify the action of terminal radio station 30B at this moment with reference to Figure 26.Figure 26 is the program flow diagram of the action in the terminal radio station 30 when shortening in the beacon signal transmission cycle of expression base station 10.
At first, the beacon signal transmission cycle that detects base station 10 shortens (YES among the S261).Then, just at executive utility (YES among the S262), and beacon signal sends period T b and is not best suited for when application program (NO among the S263), the beacon signal receiving cycle Tr in this radio station is set in the integral multiple that beacon signal sends period T b recently, and the value that is no more than (S264).
In addition, because from the requirement of certain terminal radio station 30A, base station 10 sends the cycle to beacon signal when elongated, and other-end radio station 30B can send the beacon signal of base station 10 is sent periodic change is requirement for this optimal length in radio station.In view of the above, even it is elongated by certain terminal radio station 30A the beacon signal of base station 10 to be sent the cycle, other-end radio station 30B also can keep best beacon signal receiving cycle, can suppress power consumption.In addition, at this moment, the long terminal radio station 30A of beacon signal receiving cycle is by described processing (Figure 26), and the beacon signal that the beacon signal receiving cycle is changed to base station 10 sends the length of the best in the multiple in cycle, best beacon signal receiving cycle can be kept, power consumption can be suppressed.
Specify the action in terminal radio station 30 at this moment with reference to Figure 27.Figure 27 is the program flow diagram that the beacon signal of expression base station 10 sends the action in the terminal radio station 30 of cycle when elongated.
At first, detect the beacon signal transmission cycle elongated (YES among the S271) of base station 10.Then, just at executive utility (YES among the S272), and beacon signal sends period T b and is not best suited for when application program (NO among the S273), and base station 10 is sent the change request (S274) that beacon signals send period T b.
In addition, shorten the beacon signal transmission during cycle, the requirement from whole terminals radio station 30 is accepted in base station 10, the change beacon signal sends the cycle, and the terminal radio station 30A terminal radio station 30B in addition that sends requirement can change to best length in the beacon signal multiple in transmission cycle to the beacon signal receiving cycle.In addition, when the cycle that beacon signal is sent is elongated, except from the change of default value the time, the requirement from the terminal radio station 30A of the requirement of being sent setting the present beacon signal transmission cycle is accepted in 10 of base stations, does not does not accept the requirement from addition terminal radio station 30B.At this moment, not accepted the terminal radio station 30B that beacon signal is sent elongated requirement of cycle can change to present beacon signal to the beacon signal receiving cycle in this radio station and send best length in the multiple in cycle.
With reference to Figure 28, specify the action of base station 10 at this moment.Figure 28 is the action of the base station 10 when beacon signal sends the change request in cycle is received in expression from terminal radio station 30 a program flow diagram.
At first, detect the change request (YES the S281) that beacon signal sends period T b from terminal radio station 30.Then when shortening the change request of beacon signal transmission period T b (among the S281, shorten), perhaps when setting terminal radio station 30 that present beacon signal sends period T b and receive elongated change request (YES the S285), it is effective (S283) that change request is replied in this terminal radio station 30, and the change beacon signal sends period T b (S284).
And the terminal radio station 30 beyond setting the terminal radio station 30 that present beacon signal sends period T b receives that when beacon signal sent the elongated change request of period T b (NO the S285), it is invalid (S286) that change request is replied in this terminal radio station 30.At this moment, do not change beacon signal and send period T b.
Below, with reference to Figure 29, the action in the terminal radio station 30 when requiring of shortening beacon signal transmission cycle sent in terminal radio station 30 is described.
Base station 10 is sent the change request (S291) that shortens beacon signal transmission period T b, receive response (S292) then from base station 10.
Below with reference to Figure 30 illustrate terminal radio station 30 send beacon signal send period T b elongated require the time the action in terminal radio station 30.
At first, base station 10 is sent the elongated requirement (S301) beacon signal transmission period T b, then, 10 receive response (S302) from the base station.If then response is invalid (engineering noise among the S303), just beacon signal receiving cycle Tr is set in the integral multiple that present beacon signal sends period T b the most approaching value that base station 10 is required and the value (S304) that is no more than.
Figure 31 be represent at this moment terminal radio station 30 and the sequence chart of the action of base station 10.
In the beacon signal transmission cycle of base station 10 is under the state of 100ms (default), and terminal radio station 30A requires beacon signal to send cycle 20ms, base station 10 receive it (t11).Then terminal radio station 30A 10 receives the Seeking Truth of indicating and effectively responds (t12) from the base station.At this moment, it is 20ms that base station 10 sends periodic change to beacon signal, with broadcasting this meaning is sent whole terminals radio station 30.
Then under this state, other-end radio station 30B requires beacon signal to send cycle 1000ms, base station 10 receive it (t13).For this requirement, because be that present beacon signal sends elongated requirement of cycle, and not from the change request of terminal radio station 30A that requires present beacon signal is sent the change in cycle,, this meaning is sent (t14) to terminal radio station 30B so base station 10 makes and requires invalidly.If terminal radio station 30B 10 receives the response that change request is invalid from the base station, just being set at the integral multiple that present beacon signal sends cycle 20ms is beacon signal receiving cycle 1000ms.
Then, under this state, terminal radio station 30A requires beacon signal to send cycle 1000ms, base station 10 receive it (t15).For this requirement, though be that present beacon signal sends elongated requirement of cycle, but for from the change request of terminal radio station 30A that requires present beacon signal is sent the change in cycle, require effectively, this meaning is sent (t15) to terminal radio station 30A so base station 10 makes.At this moment base station 10 is beacon signal transmission periodic change 1000ms, with broadcasting this meaning is sent whole terminals radio station 30.
Here, in the cycle that beacon signal is sent when elongated, when the value that the value that requires as the terminal radio station 30A of the requirement of being sent setting the present beacon signal transmission cycle requires than other-end radio station 30B is grown, base station 10 beacon signal send the cycle elongated after, other-end radio station 30B sends the requirement that the beacon signal transmission cycle is shortened.At this moment, before base station 10 shortened the beacon signal transmission cycle, might become other-end radio station 30 was not best state.
With reference to Figure 32 described problem is described.Figure 32 is the sequence chart of the action of expression terminal radio station 30 and base station 10.
Figure 32 is illustrated among the t13 of Figure 31, and other-end radio station 30B replaces beacon signal to send cycle 1000ms, when requiring beacon signal to send cycle 500ms (t13 ').For this requirement, because be that present beacon signal sends elongated requirement of cycle, and not from the change request of terminal radio station 30A that requires present beacon signal is sent the change in cycle,, this meaning is sent (t14) to terminal radio station 30B so base station 10 makes and requires invalidly.If terminal radio station 30B 10 receives the response that change request is invalid from the base station, just being set at the integral multiple that present beacon signal sends cycle 20ms is beacon signal receiving cycle 5000ms.
Same with Figure 31 then, for this requirement, though be that present beacon signal sends elongated requirement of cycle, but for from the change request of terminal radio station 30A that requires present beacon signal is sent the change in cycle, require effectively so base station 10 makes, this meaning is sent (t15) to terminal radio station 30B.At this moment base station 10 is beacon signal transmission periodic change 1000ms, with broadcasting this meaning is sent whole terminals radio station 30.
At this moment, because for beacon signal receiving cycle 500ms, the beacon signal transmission cycle is 1000ms, so terminal radio station 30B requires beacon signal to send cycle 500ms (t17) to base station 10.According to this requirement, base station 10 sends the cycle to beacon signal to 500ms change (t18).; from the requirement according to terminal radio station 30A, it is 1000ms that beacon signal sends periodic change, to the requirement according to terminal radio station 30B; it is between the 500ms that beacon signal sends periodic change, and becoming for terminal radio station 30B is not the state that best beacon signal sends the cycle.
Therefore, when from send present beacon signal send terminal radio station 30A handlebar beacon signal that the setting in cycle requires send the cycle elongated require the time, base station 10 judges whether to communicate by letter with other-end radio station 30B, when communicating by letter, relatively the beacon signal that requires of other-end radio station 30B sends the cycle and sends present beacon signal and sends the beacon signal that terminal radio station 30A that the setting in cycle requires requires and send the cycle, beacon signal is sent the value of periodic change for a short side, and when not communicating by letter, change to and send present beacon signal and send the value that terminal radio station 30A that the setting in cycle requires requires.In view of the above, all the beacon signal reception interval for this radio station the best can be set in terminal radio station 30, can suppress power consumption.
Here, in base station 10, communication control unit 15 selects beacon signal the shortest in the terminal radio station 30 in the described communication to send the processing in cycle.Particularly, communication control unit 15 is when receiving when becoming the beacon signal transmission cycle than present longer the requirement, judges whether it is the requirement in terminal radio station 30 that present beacon signal is sent the requirement of periodic change from sending.Then, communication control unit 15 is judged as from sending when present beacon signal sent the requiring of terminal radio station 30 of requirement of periodic change, and as requested, the change beacon signal sends the cycle.In addition, communication control unit 15 keeps the beacon signal transmission cycle that the terminal radio station 30 in the communication requires.Then, the shortest value in the beacon signal transmission cycle of terminal radio station 30 requirements of communication control unit 15 selections from communication.
Specify the action of base station 10 at this moment with reference to Figure 33.Figure 33 is the action of the base station 10 when beacon signal sends the change request in cycle is received in expression from terminal radio station 30 a program flow diagram.In addition, the program flow diagram in terminal radio station 30 is identical with Figure 29, Figure 30.
At first, detect the change request (YES the S281) that beacon signal sends period T b from terminal radio station 30.Then the change request as shortening beacon signal transmission period T b is (among the S282 " shortening "), and it is effective (S283) that change request is replied in terminal radio station 30, and the change beacon signal sends period T b (S284).
In addition, when when setting present beacon signal and send period T b terminal radio station 30 and receive elongated change request (among S285, YES), other-end radio station 30 in the existence communication, and judge that the beacon signal that other-end radio station 30 requires sends also short (S311, the S312) of beacon signal transmission period T b that whether exists among the period T b ' than newly receiving.Then, the beacon signal that requires when the other-end radio station in the communication 30 sends not exist among the period T b ' than the beacon signal of newly receiving and sends the also short time (NO among the S311 of period T b, or YES among the S312), it is effective (S283) that change request is replied in terminal radio station 30, and the change beacon signal sends period T b (S284).
Existence sends the also short time (YES among the S311 of period T b than the beacon signal of newly receiving among the period T b ' and the beacon signal that requires when the other-end radio station in the communication 30 sends, or NO among the S312), it is invalid (S286) that change request is replied in terminal radio station 30, and the change beacon signal sends period T b ' (S313).In view of the above, can change to beacon signal the shortest in the terminal radio station 30 in the communication and send period T b '.
Figure 34 be represent at this moment terminal radio station 30 and the sequence chart of the action of base station 10.
The beacon signal transmission cycle of base station 10 is under the state of 100ms (default), and terminal radio station 30A requires beacon signal to send cycle 20ms, base station 10 receive it (t21).Then 10 reception expressions require effectively response (t22) to terminal radio station 30A from the base station.At this moment, it is 20ms that base station 10 sends periodic change to beacon signal, with broadcasting this meaning is sent whole terminals radio station 30.
Then under this state, other-end radio station 30B requires beacon signal to send cycle 500ms, base station 10 receive it (t23).For this requirement, because be that present beacon signal sends elongated requirement of cycle, and not from the change request of terminal radio station 30A that requires present beacon signal is sent the change in cycle,, this meaning is sent (t24) to terminal radio station 30B so base station 10 makes and requires invalidly.If terminal radio station 30B 10 receives the response that change request is invalid from the base station, just being set at the integral multiple that present beacon signal sends cycle 20ms is beacon signal receiving cycle 500ms.
Then, under this state, terminal radio station 30A requires beacon signal to send cycle 1000ms, base station 10 receive it (t25).For this requirement, though be that present beacon signal sends elongated requirement of cycle, but for from the change request of terminal radio station 30A that requires present beacon signal is sent the change in cycle, the other-end radio station 30B that is now communicating by letter is arranged, and it is short to send cycle 500ms from the beacon signal that terminal radio station 30B requires, so base station 10 makes the change request of self terminal radio station 30A invalid, this meaning is sent (t26) to terminal radio station 30A.At this moment the shortest beacon signals in terminal radio station 30 that change in the communication of base station 10 send cycle 500ms, with broadcasting this meaning are sent whole terminals radio station 30.In addition, to be set at the integral multiple that present beacon signal sends cycle 500ms be beacon signal receiving cycle 1000ms to terminal radio station 30A.
In addition, terminal of the present invention radio station is made of base station and 2 terminal radio station at least, the transmission cycle of the regular signal (beacon signal) that sends from the base station is notified the terminal radio station, in the A of terminal radio station, require parts (end side wireless communication part 36) by the setting of transmission cycle, the base station sent set the transmission cycle than now short requirement, in the base station, has the setting requirement of receiving according to from terminal radio station A, is the transmission periodic change of regular signal than in short-term now, terminal radio station beyond the A of terminal radio station is set at the receiving cycle that receives regular signal the receiving cycle set parts (end side wireless communication part 36) of multiple in the transmission cycle of the regular signal of base station transmission.
In addition, base station of the present invention can have: requiring when described setting is the transmission periodic change that makes regular signal for than now longer the requirement time, judges whether it is terminal radio station decision means (communication control unit 15) from the requirement in the terminal radio station of being sent change request the present transmission cycle.In addition, the transmission cycle of described regular signal is changed in base station of the present invention when being judged as from the requiring of the terminal radio station of being sent change request the present transmission cycle by described terminal radio station decision means.In addition, base station of the present invention has when being judged as from the requiring of the terminal radio station of being sent change request the present transmission cycle by described terminal radio station decision means, judge whether with the terminal radio station of sending described requirement beyond the decision means of communicating by letter (communication control unit 15) of terminal station telecommunication; Be judged as when just communicating by described communication decision means, change to the transmission cycle of short value that requires in the whole terminals radio station in the communication with the other-end radio station.
