Description
Technical field
The present invention relates to the communications field, particularly relate to a kind of power-saving control method.
Background technology
In WiMAX standard, power saving management is specified.In 802.16e agreement, its medium access controls (Media Access Control, referred to as MAC) layer protocol defines operation of sleep mode, park mode is travelling carriage (Mobile Station, referred to as MS) to serving BS (Base Station, referred to as BS) preengage the sleep window changed according to certain rule for certain business arranged, (time zone can not be obtained) when all business are all in sleep window, be in the angle of serving BS broadcasts, uplink service and downlink business, this MS is all unavailable, namely, can not obtain in time zone, transfer of data cannot be carried out between serving BS broadcasts and MS.Pass through park mode, MS according to oneself requirement, can close R-T unit and makes control system enter power down mode, reducing the energy ezpenditure of MS, and the air interface resource of serving BS broadcasts can be saved, make the air interface resource saved can provide service for more MS.
At present, in 802.16e agreement, business is divided into 4 kinds of COS: unsolicited frequency range distributes (Unsolicited Grant Service, referred to as UGS), Real-time Polling Service (Real-Time Polling Service, referred to as rtPS), non-Real-time polling service (NonReal-Time Polling Service, referred to as nrtPS) and the service of doing one's best (Besteffort, referred to as BE).
Below the feature of UGS, rtPS, nrtPS and BE4 kind business is described.
UGS:UGS business is the business that priority is the highest, and when carrying out the business transmission of UGS COS, MS does not need to send polling request when carrying out transfer of data at every turn to BS, but after MS accesses BS, can meet the data demand of this business with fixing bandwidth.Particularly, every fixing superframe just for such business provides the space of data transmit-receive, the CBR business of the voice coder code stream, T1/E1 business and so on not having silence compression is applicable to.
RtP: when carrying out the transmission of rtP business, before carrying out transfer of data, MS can send bandwidth application to BS at every turn, carries the bandwidth needed for this data transfer in this bandwidth application, like this, although can optimized transmission speed, too increases the expense of signaling.Such business is mainly used in real-time multimedia traffic, such as, video flowing and audio stream, have silence compression audio stream be then called subclass under such, be called ertPS (real-time polling service of expansion), such business is generally RT-VR (real-time variable Rate) business.
NrtPS: non real-timely to refer to: be not starting stage of transfer of data just propose transmission application, but need certain hour could obtain once polled chance, although nrtPS business has certain protection, but rank is lower, such business is NRT-VR (non real-time variable Rate) business mainly.
BE: when carrying out the transmission of BE business, have unnecessary bandwidth that BE business just can be allowed to send application, and compete bandwidth, therefore the protection of BE business is poor.
The sleep for electricity saving pattern that different types of service is corresponding different, is described the sleep for electricity saving pattern of different service types below.For this four classes business, 802.16e_MAC layer protocol gives three kinds of dormancy algorithms.
Dormancy algorithm 1: sleep window exponential increasing algorithm is applicable to the connection of BE, NRT-VR type service.
The dormancy mechanism of dormancy algorithm 1 is: when business enters park mode, and namely park mode is activated at a certain frame, then current hibernation window is set to initial value, and every frame subtracts 1 from next frame, and start counting, when counting reaches 0, MS revives and enters audit window.If MS does not receive the signaling leaving park mode at audit window, after audit window terminates, then continue to enter next sleep window adjacent with above-mentioned current hibernation window, the length of this sleep window is 2 times of current hibernation window, but can not exceed the max-thresholds of the sleep window pre-set.According to this dormancy mechanism, after each audit window terminates, enter dormancy, and, current hibernation window=min (the front sleep window of 2*, maximum sleep window radix * 2
maximum sleep widow index)
By dormancy algorithm 1, the audit window of sleep window and fixed size interlocks in time.Within the monitoring phase, MS and BS can carry out the transmission of signaling and data, can effectively save energy and interface-free resources within rest period.
Dormancy algorithm 2: sleep window algorithm is adapted to the connection of UGS, RT-VR type at equal intervals
The dormancy mechanism of dormancy algorithm 2 is: enter park mode in business, and namely park mode is after a certain frame is activated, then current hibernation window is set to initial value.And every frame subtracts 1 counting from next frame, when counting reaches 0, MS revives and enters audit window.If MS does not receive at audit window terminate the signaling of sleep window, then once sleep window on entering after audit window terminates, the length of this sleep window is equal with the length of current hibernation window.
Can find out, park mode 2 times, sleep window and the audit window of fixed size interlock in time.Within the monitoring phase, MS and BS can carry out the transmission of signaling and data, can effectively save energy and interface-free resources within rest period.
Dormancy algorithm 3: single dormancy algorithm is applicable to multicast and signalling, and such is connected and bookkeeping for multicast.
The dormancy mechanism of dormancy algorithm 3 is: after a certain frame activates such dormancy algorithm, MS enters current hibernation window, and the length of this sleep window equals preset initial value, and every frame subtracts 1 from next frame, when counting arrival 0, dormancy terminates, and MS returns to active state.
Dormancy algorithm 3 with the difference of above-mentioned two kinds of dormancy algorithms is: in dormancy algorithm 3, only can enter the sleep window that has preset length, and, after the dormancy in this sleep window terminates, dormancy will terminate, and can not enter next sleep window.
Real-time multimedia traffic is generally classified as RT type of service (having the business of requirement of real time), in order to ensure the requirement of real time of business, dormancy algorithm 2 can be selected to carry out power saving management.Such as, when power saving management is carried out to the speech business of silence compression, generally dormancy algorithm 2 can be adopted.Adopt the sleep procedure of dormancy algorithm 2 as shown in Figure 1, when being managed by the speech business of dormancy algorithm 2 pairs of silence compression, active period and the quiet period of speech business stream can not be distinguished, during active period or during quiet period, for meeting service quality, all can revive at equal intervals according to the space requirement of active period and monitoring and data transmission.
In order to ensure service quality (the Quality of Service of business, referred to as QoS), when arranging the length of sleep window, must ensure that the time delay (delay) produced because of dormancy is less than the queuing delay of this business permission in terminal generation, the length therefore arranging sleep window can not be excessive.Like this, because the length of the sleep window in quiet period is less, invalid monitoring number of times can be caused too many, because state switching and the energy loss monitored and cause be can not ignore, so when adopting dormancy algorithm 2, power saving efficiency is not high, can not reach the object of power and energy saving.

Functional overview
The present invention mainly for be real-time multimedia traffic, the type mainly voice of common real-time multimedia traffic, video traffic is the main business that WiMAX system carries.Inhomogeneous multimedia service, the burst mechanism of business also has difference.In the business categorizing that 802.16e has provided, multimedia service is included in this type of service of rtPs, is applicable to power saving class II---sleep window algorithm at equal intervals.And the main path signal in the real-time multimedia traffic stream of reality mostly is voice signal, MS is in the process of single channel voice communication, normally active period (talk spurt) and quiet period (silence) occur alternately, the average that active period continues duration is 1.587s, quiet period continues duration and treats that average is 1.004s, can find out, the lasting duration of this two states is all stochastic variable, meets quantum condition entropy.Under active period, transfer of data produces at equal intervals (such as: G.711 encoding frame interval is 20ms), and entering quiet period does not then have transfer of data for a long time.
Speech business comprises active period and quiet period, and active period length and the quiet period distribution of lengths of speech business all meet quantum condition entropy.Wherein, active period has speech data transmission, but unnecessary every frame all transmits data, and quiet period does not have voice data transmission.Therefore, speech business characteristic can be made full use of to design the electricity-saving mechanism of applicable speech business.
Carrying out power saving management to make full use of speech business characteristic, audit window and the sleep window of fixed intervals can be adopted in active period; And in the sleep window that quiet period adopts binary system to successively decrease.In quiet period at the end of each sleep window, terminal is monitored the need of entering active period at audit window, if do not need to enter active period, then continues next sleep window; After each sleep window terminates, need to enter active period if listened at audit window, then carry out power saving according to the battery saving mode of active period, namely adopt audit window and the sleep window of regular length; Listen in active period and need to enter quiet period, then carry out power saving according to the battery saving mode of quiet period.To the requirement of quiet period sleep window Design of length demand fulfillment two aspect.Be at utmost power saving on the one hand, initial dormancy, as far as possible close to the length of quiet period, reduces quiet period sleep window number so as far as possible; On the other hand in order to meet the qos requirement of speech business, also needing in quiet period can voice responsive data and enter active period timely, and this needs sleep window short as far as possible.The demand on this two sides is contradiction, and this just must need to design sleep window Changing Pattern in quiet period according to the statistics duration regularity of distribution of quiet period, on the basis meeting QoS characteristic, and power saving as far as possible.
When not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
Embodiment of the method one
According to the embodiment of the present invention, provide a kind of power-saving control method.
Fig. 2 is the flow chart of the power-saving control method according to the embodiment of the present invention, the method is mainly used in business that right length meets quantum condition entropy and carries out economize on electricity and control, such as, if the quiet period length of speech business meets quantum condition entropy, then can change according to the sleep window length of the method to quiet period, as shown in Figure 2, the method comprises the following steps (step S202 is to step S204).
Step S202, battery saving mode comprises following parameter one of at least: initial sleep window length, final sleep window length, the length variations rule of sleep window, the audit window regularity of distribution, particularly, can arrange the parameter of this battery saving mode, afterwards, control if terminal needs to carry out economize on electricity by this battery saving mode, base station can by the parameter notifications of this battery saving mode to terminal;
Step S204, when entering battery saving mode, using initial sleep window length as current hibernation length of window, determines the length of next sleep window according to the length variations rule of sleep window and the length of final sleep window.
In specific implementation process, first battery saving mode is arranged: the first, arrange the length (that is, initial sleep window length mentioned above) entering first sleep window of quiet period, the length of this first sleep window can be arranged as required flexibly, such as, 640ms; Second: the length arranging final sleep window, this sleep window length also can be arranged as required flexibly, such as, and 160ms, 80ms etc.; 3rd, the length variations rule of sleep window is set, main thought is: the computing length of current hibernation window being carried out to mathematical formulae, and using the interim length of the result after computing as next sleep window, such as, this Changing Pattern can be: using the interim length of the half of current hibernation length of window as next sleep window; 4th, the audit window regularity of distribution is set.For convenience, below with the length of first sleep window for 640ms, final sleep window length is 160ms, the length variations rule of sleep window is that example is described using the half of current hibernation length of window as the interim length of next sleep window, like this, the length of next sleep window can be obtained according to the length of the length variations rule of sleep window and final sleep window, namely, the interim length of next sleep window and the length of final sleep window are compared, and using the wherein larger length as next sleep window.By this battery saving mode, because initial sleep window is comparatively large, effectively can reduce the wake up operations of MS in quiet period, reach the object of saving energy and switching and monitoring energy.
Terminal or base station are by voice coder code stream, detect/(this operation can be realized by existing method after lang sound business enters into quiet period, such as, current speech coding comprises detection option of mourning in silence), first first sleep window can be determined, first sleep window (namely, initial sleep window above) length be 640ms, and the current window proceeded to is defined as current hibernation window, because the current window proceeded to is first sleep window, then this first sleep window is current hibernation window.
After first sleep window terminates, if terminal does not receive one of following information at audit window: business, business indicates, exit the signaling instruction of battery saving mode, then enter next sleep window immediately, according to the length variations rule of above-mentioned sleep window, the length of first sleep window can reduce half, namely, 320ms, this 320ms and final sleep window length 80ms is compared, and using the wherein larger length as second sleep window, like this, the length of second sleep window is 320ms, now, second sleep window is new current hibernation window,
After first sleep window terminates, if terminal receives one of following information at audit window: business, business indicate, exit the signaling instruction of battery saving mode, then exit current battery saving mode.
According to said method, according to the length variations rule of above-mentioned sleep window, the length of the 3rd sleep window is obtained by the length of the second sleep window, by that analogy, if the interim length of amended next sleep window equals 80ms, then before business enters active period, keep 80ms as the length of new current hibernation window.Like this, according to the length variations rule of sleep window, in this battery saving mode, the length of next sleep window can be obtained according to following formula: the length=Max (length of 0.5* current hibernation window, final sleep window length) of next sleep window.It should be noted that, if the length of next sleep window equals final sleep window length, then, before exiting this battery saving mode, the length of subsequent sleep window no longer changes, and is equal to each other, and is final sleep window length.
By the sleep window of this exponential decrease, the length of sleep window reduces speed ratio comparatively fast, can return to smaller listening intervals very soon, like this, can ensure that time delay average is within the QoS scope of business need after minority is revived several times.
Preferably, as shown in Figure 3, MS or BS is after detecting that uplink/downlink voice flow enters quiet period, above-mentioned power-saving control method can be started by signaling MOB_SLP-RSP, and after Signalling exchange, enter initial sleep window, and using this initial sleep window as current hibernation window, after current hibernation window terminates, if do not need to enter active period, then pass through formula: length=Max (length of 0.5* current window of next sleep window, final sleep window length), enter next sleep window, using this next sleep window as new current hibernation window, according to above-mentioned formula, by that analogy, if the length of certain next sleep window equals final sleep window length, then before exiting this battery saving mode, the length of the sleep window after certain next sleep window is final sleep window length.
In addition, when business is in hibernation, at the end of sleep window, MS revives and monitors, if do not have data downstream transmission, then continues to enter next sleep window.
The quiet period length that above-mentioned battery saving mode goes for business meets the business of quantum condition entropy, such as, and the business of silence compression type.
By the technical scheme that the embodiment of the present invention provides, the present invention proposes a kind of new electricity-saving mechanism, consider the traffic performance in speak silence interval, the sleep window of quiet period is that negative exponent is successively decreased, make full use of the characteristic of business, the efficiency of energy and air resource can be saved, and make the time delay average of business within the QoS scope of this business need.
Further, this mechanism can obtain the support of speech coding, and existing voice coding is mourned in silence detections, and scheme realize only needing data packet head prompting mourn in silence detect effective.
Embodiment of the method two
According to the embodiment of the present invention, provide a kind of power-saving control method, wherein, the method comprises: business comprises the active period and quiet period that periodically replace, and wherein, active period and quiet period adopt different battery saving modes.
Because active period and quiet period adopt different battery saving modes, then, when carrying out power saving management, need the conversion carrying out battery saving mode between active period and quiet period, or, carry out the conversion of battery saving mode between quiet period and active period.Wherein, the conversion of battery saving mode can have been indicated by signaling, also can be completed by implicit instruction.This implicit instruction refers to: the active period instruction in the corresponding coding of business or quiet period instruction, and such as, for voice service, implicit instruction can be that the active period in speech coding indicates or quiet period instruction.
Different battery saving modes is adopted to be specifically described to active period and quiet period below:
In active, the sleep window that the battery saving mode of active period can be replaced by the cycle and audit window represent, wherein, the length of audit window can adopt fixed value, and the length of sleep window can adopt fixed value or binary system increment mode or other rule to change.
In quiet period, the battery saving mode of quiet period is represented by cycle alternatively distributed sleep window and audit window, further, the battery saving mode of described quiet period comprises following parameter one of at least: initial sleep window length, final sleep window length, the Changing Pattern of sleep window, audit window distribution of lengths rule.Wherein, the thinking of wanting of the length variations rule of sleep window is: the computing length of current hibernation window being carried out to mathematical formulae, and using the interim length of the result after computing as next sleep window, such as, this Changing Pattern can be: using the interim length of the half of current hibernation length of window as next sleep window, afterwards, can according to the length of this Changing Pattern and final sleep window and the length obtaining next sleep window, and using next sleep window as new current hibernation window.
In addition, at the end of current hibernation window, if do not receive one of following information at audit window: business, enter active period business instruction, exit the instruction of current battery saving mode, then enter next sleep window; If terminal receives one of following information at audit window: business, enter active period business instruction, enter active period signaling instruction, be then transformed into the battery saving mode of active period.
Be described the power-saving control method shown in the embodiment of the present invention two below in conjunction with accompanying drawing, as shown in Figure 4, the method comprises the following steps (step S402 is to step S406).
Step S402, terminal obtains the battery saving mode parameter of active period and quiet period, and the battery saving mode parameter of active period comprises: the length of audit window is set to fixed value, and the length of sleep window is set to pattern that fixed value or binary system increase progressively or other Changing Patterns; The battery saving mode of quiet period comprises following parameter one of at least: initial sleep window length, final sleep window length, the Changing Pattern of sleep window, audit window distribution of lengths rule.
Step S404, terminal detects and enters quiet period, using the length of the initial sleep window length of the quiet period of business as current hibernation window;
Step S406, in quiet period, at the end of current hibernation window, if do not receive one of following information at audit window: business, enter active period business instruction, exit the instruction of current battery saving mode, then according to the length of the length variations rule of sleep window and final sleep window and the length obtaining next sleep window, and using next sleep window as new current hibernation window.
In specific implementation process, first battery saving mode is arranged: the first, arrange the length (that is, initial sleep window length mentioned above) entering first sleep window of quiet period, the length of this first sleep window can be arranged as required flexibly, such as, 640ms; Second: the length arranging final sleep window, this sleep window length also can be arranged as required flexibly, such as, and 160ms, 80ms etc.; 3rd, the length variations rule of sleep window is set, main thought is: the computing length of current hibernation window being carried out to mathematical formulae, and using the interim length of the result after computing as next sleep window, such as, this Changing Pattern can be: using the interim length of the half of current hibernation length of window as next sleep window; 4th, the audit window regularity of distribution is set.For convenience, below with the length of first sleep window for 640ms, final sleep window length is 160ms, the length variations rule of sleep window is that example is described using the half of current hibernation length of window as the interim length of next sleep window, like this, the length of next sleep window can be obtained according to the length of the length variations rule of sleep window and final sleep window, namely, the interim length of next sleep window and the length of final sleep window are compared, and using the wherein larger length as next sleep window.By this battery saving mode, because initial sleep window is comparatively large, effectively can reduce the wake up operations of MS in quiet period, reach the object of saving energy and switching and monitoring energy.
Terminal or base station are by voice coder code stream, if detect/(this operation can be realized by existing method after lang sound business enters into active period, such as, current speech coding comprises enlivens detection option), then sleep window during business active period is defined as a fixed value, that is, as long as this business is in active period, each sleep window is during this period identical value; Or, change the sleep window in active period according to binary system increment mode.
Terminal or base station are by voice coder code stream, detect/(this operation can be realized by existing method after lang sound business enters into quiet period, such as, current speech coding comprises detection option of mourning in silence), first first sleep window can be determined, first sleep window (namely, initial sleep window above) length be 640ms, and the current window proceeded to is defined as current hibernation window, because the current window proceeded to is first sleep window, then this first sleep window is current hibernation window.
After first sleep window terminates, if terminal does not receive one of following information at audit window: business, enter the business instruction of active period, exit the signaling instruction of battery saving mode, then enter next sleep window immediately, according to the length variations rule of above-mentioned sleep window, the length of first sleep window can reduce half, namely, 320ms, this 320ms and final sleep window length 80ms is compared, and using the wherein larger length as second sleep window, like this, the length of second sleep window is 320ms, now, second sleep window is new current hibernation window,
After first sleep window terminates, if terminal receives one of following information at audit window: business, business indicate, exit the signaling instruction of battery saving mode, then exit current battery saving mode.
According to said method, according to the length variations rule of above-mentioned sleep window, the length of the 3rd sleep window is obtained by the length of the second sleep window, by that analogy, if the interim length of amended next sleep window equals 80ms, then before business enters active period, keep 80ms as the length of new current hibernation window.Like this, according to the length variations rule of sleep window, in this battery saving mode, the length of next sleep window can be obtained according to following formula: the length=Max (length of 0.5* current hibernation window, final sleep window length) of next sleep window.It should be noted that, if the length of next sleep window equals final sleep window length, then, before exiting this battery saving mode, the length of subsequent sleep window no longer changes, and is equal to each other, and is final sleep window length.
By the sleep window of this exponential decrease, the length of sleep window reduces speed ratio comparatively fast, can return to smaller listening intervals very soon, like this, can ensure that time delay average is within the QoS scope of business need after minority is revived several times.
Preferably, as shown in Figure 5, MS or BS is after detecting that uplink/downlink voice flow enters quiet period, above-mentioned power-saving control method can be started by signaling MOB_SLP-RSP, and after Signalling exchange, enter initial sleep window, and using this initial sleep window as current hibernation window, after current hibernation window terminates, if do not need to enter active period, then pass through formula: length=Max (length of 0.5* current window of next sleep window, final sleep window length), enter next sleep window, using this next sleep window as new current hibernation window, according to above-mentioned formula, by that analogy, if the length of certain next sleep window equals final sleep window length, then before exiting this battery saving mode, the length of the sleep window after certain next sleep window is final sleep window length.
In quiet period, monitor after MS after sleep window terminates revives, find that there is transfer of data, then enter active period; The battery saving mode of active period is then adopted in active period, this battery saving mode can adopt the audit window of regular length, and meet the sleep window of certain Changing Pattern, such as, the length of this sleep window adopts fixed value or binary system increment mode or other rule to change, and after audit window completes data transmission, enters sleep window, and the length of sleep window changes according to above-mentioned rule, circulates with this.
By the technical scheme that the embodiment of the present invention provides, the present invention is by the active period and quiet period of business, adopt different algorithms respectively, solve the coordination problem when coordination of up-downgoing business and real-time multimedia traffic comprise multipath media stream, and by the application of energy-saving mode in multichannel is coordinated of successively decreasing, effectively energy can be saved.
Further, this mechanism can obtain the support of speech coding, and existing voice coding is mourned in silence detections, and scheme realize only needing data packet head prompting mourn in silence detect effective.
Embodiment of the method three
Fig. 6 is the flow chart of the power-saving control method according to the embodiment of the present invention, and as shown in Figure 6, the method comprises the following steps (step S602 is to step S604).
Step S602, battery saving mode comprises following parameter one of at least: the length variations rule of initial dormancy period length, final dormancy period length, dormancy period, particularly, the feature of the business can carried out according to terminal, determine the length variations rule of dormancy period, wherein, dormancy period comprises audit window and sleep window, and the length of dormancy period is the length sum of sleep window and audit window.
Step S604, when entering battery saving mode, using initial dormancy period length as current hibernation Cycle Length, determines the length of next dormancy period according to the length variations rule of dormancy period and the length of final dormancy period.
Particularly, the length of next dormancy period can be determined according to following three kinds of modes:
Mode one: the length of dormancy period changes according to binary system production decline law
First the length in current hibernation cycle is reduced half, as the interim length of next dormancy period, and the length of next dormancy period is obtained according to the interim length of final dormancy period length and next dormancy period, using next dormancy period as the new current hibernation cycle, be specially: the interim length of next dormancy period and final dormancy period length are compared, and using the wherein larger length as next dormancy period, such as, the length of next dormancy period can be determined: length=Max (length in 0.5* current hibernation cycle of next dormancy period according to following formula, final dormancy period length), especially, if the interim length of next dormancy period equals final dormancy period length, then before business enters active period, keep the length of final dormancy period length as the new current hibernation cycle.Wherein, the size of the length of initial dormancy period is 640ms, and the size of the length of minimum dormancy period is 160ms or 80ms.
Mode two: the length of dormancy period changes according to binary system progressive law
First the length in current hibernation cycle is doubled, as the interim length of next dormancy period, and the length of next dormancy period is obtained according to the interim length of final dormancy period length and next dormancy period, using next dormancy period as the new current hibernation cycle, be specially: the interim length of next dormancy period and final dormancy period length are compared, and using the wherein less length as next dormancy period, such as, the length of next dormancy period can be determined: length=Min (length in 2* current hibernation cycle of next dormancy period according to following formula, final dormancy period length), if the interim length of next dormancy period equals final dormancy period length, then before business enters active period, keep the length of final dormancy period length as the new current hibernation cycle.
