Embodiment four
Cardinal principle flow process in fourth embodiment of the invention can in the present embodiment, will be described in detail condition that starts energy-saving mode and the detailed process of judging referring to third embodiment of the invention.In addition, energy-saving mode can have only a kind of, and two kinds of degree of depth energy-saving mode and shallow degree energy-saving modes also can be arranged, and perhaps exists multiplely, and the embodiment of the invention will be described as an example with one or both situation.
Such as, judge not have state of activation UE or to exist the sub-district of state of activation UE whether to satisfy the condition of default startup energy-saving mode, can be described below respectively:
In the sub-district, do not have state of activation UE, can think and satisfy the condition that starts energy-saving mode, thereby startup is at the energy-saving mode of sub-district.In this case, can be understood as, whether exist state of activation UE to can be used as the Rule of judgment or the foundation of judging unit in the sub-district, in the sub-district, do not have state of activation UE, can think and satisfy the condition that starts energy-saving mode.
When having state of activation UE in the sub-district, can judge that whether this sub-district satisfy the condition of default startup energy-saving mode, concrete, comprise one of following or its combination: judge whether state of activation UE quantity satisfies first condition in the sub-district; Whether the resource of judging the required distribution of state of activation UE in the sub-district satisfies second condition; Judge whether state of activation UE telecommunication service quality and running time-frequency resource utilance satisfy the 3rd condition in the sub-district; Judge whether the sub-district satisfies the 4th condition at the average throughput of Preset Time; Whether the power down switch of judging the sub-district webmaster is provided with described sub-district enters energy-saving mode; Judge whether the residing electrical network in sub-district belongs to the power emergency state.
There to be state of activation UE in the sub-district is example, and detailed process is exemplified below:
Mode one
By judging in the sub-district whether state of activation UE quantity satisfies the first pre-conditioned decision and whether start the sub-district and enter energy-saving mode.
This first pre-conditioned can be a predefined thresholding, the quantity of state of activation UE then starts the sub-district and enters energy-saving mode less than this thresholding in the sub-district.For example, whether whether start the sub-district by the quantity of judging state of activation UE in the sub-district and enter energy-saving mode less than the decision of first thresholding.When judged result be the quantity of state of activation UE in the sub-district less than first thresholding, then decision starts the sub-district and enters energy-saving mode; When judged result is that the quantity of state of activation UE in the sub-district is not less than first thresholding, then decision does not start the sub-district and enters energy-saving mode.
Particularly, can be quantity and the predefined thresholding contrast of definition according to activated state UE, suppose that the sub-district supports that under energy-saving mode activated state UE quantity thresholding is N, and this moment, the sub-district was in normal mode, if state of activation UE quantity is M, and M is less than N, and then switching cell enters energy-saving mode.The sub-district enters energy-saving mode can switch the CRS pattern and enter energy-saving mode, does not all send CRS on each subframe, only sends CRS on some or several subframes.
Also can in judgement, further introduce timer.Suppose that the sub-district supports that under energy-saving mode state of activation UE quantity thresholding is N, and this moment, the sub-district was in normal mode, then at t1 constantly, this moment, activated state UE quantity was M, if M＜N then starts timer T Save, if timer expiry, M＜N still, then the CRS pattern of switching cell is an energy-saving mode; As the not overtime M＞N that occurred of timing, then stop timer.If t2 at a time, the quantity M of the activated state UE＞N sub-district in, startup timer T Nor, if timer expiry, the CRS pattern of still M＞N, and this moment sub-district is an energy-saving mode, then the pattern of switching cell is a normal mode.Above-mentioned timer is selectable, can adopt, and also can.
Perhaps, when the sub-district exists degree of depth energy-saving mode and shallow degree energy-saving mode, be in first interval or in second interval by the quantity of judging state of activation UE in the sub-district, deciding startup sub-district energy-saving mode is degree of depth energy-saving mode or shallow degree energy-saving mode.Selected part number of sub-frames is less than selected part number of sub-frames under the shallow degree energy-saving mode under the degree of depth energy-saving mode.If the result who judges is in first interval, then starting energy-saving mode is degree of depth energy-saving mode, if the result who judges is in second interval, then starting energy-saving mode is shallow degree energy-saving mode.
Herein first interval and second interval can be limited by two thresholdings.For example, suppose that the sub-district supports that under shallow degree energy-saving mode state of activation UE quantity thresholding is N1, the sub-district supports that under shallow degree energy-saving mode activated state UE quantity thresholding is N2, and be in normal mode this moment, if activated state UE quantity is M, if M＜N1, then the CRS mode switch sub-district by switching cell enters shallow degree energy-saving mode, in the case, if state of activation UE quantity M＜N2, then the CRS mode switch sub-district by switching cell enters degree of depth energy-saving mode.If the sub-district has been in shallow degree energy-saving mode, at a time find state of activation UE quantity M＞N1, then the CRS pattern by switching cell switches to normal mode with the sub-district from shallow degree energy-saving mode.
Also can in judgement, further introduce timer.Suppose that the sub-district supports that under shallow degree energy-saving mode activated state UE quantity thresholding is N1, and be in normal mode this moment that then at t1 constantly, this moment, activated state UE quantity was M, if M＜N1 then starts timer T Slight, if timer expiry, M＜N1 still, then the CRS pattern of switching cell is shallow degree energy-saving mode; As the not overtime M＞N1 that occurred of timing, then stop timer.Suppose that the sub-district supports that under the degree of depth energy-saving mode activated state UE quantity thresholding is N2, and this moment, the sub-district was in shallow degree energy-saving mode, then at t2 constantly, this moment, activated state UE quantity was M, if M＜N2 then starts timer T High, if timer expiry, M＜N2 still, then the CRS pattern of switching cell is a degree of depth energy-saving mode; As the not overtime M＞N1 that occurred of timing, then stop timer.If t3 at a time, the quantity N1 of the activated state UE＞M＞N2 sub-district in, and the CRS pattern of sub-district is a degree of depth energy-saving mode at this moment, then the pattern of switching cell is shallow degree energy-saving mode.But, if t3 at a time, the quantity M of the activated state UE＞N1 sub-district in, and this moment the sub-district the CRS pattern be shallow degree energy-saving mode, startup timer T Nor, if timer expiry, M＞N1 still, then the pattern of switching cell is a normal mode.Above-mentioned timer is selectable, can adopt, and also can.
Be understandable that, the implementation of mode one can also can be realized the economize on electricity of system so that during the activated state subscriber equipment of sub-district in having some scopes, the prior art of comparing has enlarged the scope that energy-saving mode is used, and has further saved system energy consumption.
In addition, in judgement, adopt timer, can be under the activated state number of users keeps stable prerequisite in a period of time relatively, decision starts switching from the normal mode to the energy-saving mode or the switching from the energy-saving mode to the normal mode again, avoid the sub-district between normal mode and energy-saving mode, frequently to switch, further guaranteed the stability of system.
Mode two
By judging whether the required Resources allocation of state of activation UE in the sub-district satisfies the second pre-conditioned decision and whether start the sub-district and enter energy-saving mode.
This second pre-conditioned can be a predefined thresholding, the required Resources allocation of state of activation UE then starts the sub-district and enters energy-saving mode less than this thresholding in the sub-district.For example, whether whether start the sub-district by the resource of judging required distribution in the sub-district and enter energy-saving mode less than the decision of second thresholding.When judged result be the resource of required distribution in the sub-district less than second thresholding, then decision starts the sub-district and enters energy-saving mode; When judged result is that the resource of required distribution in the sub-district is not less than second thresholding, then decision does not start the sub-district and enters energy-saving mode.
The required Resources allocation of state of activation UE can embody by total traffic.Accordingly, it is second pre-conditioned, concrete whether the total traffic that can judge state of activation UE in the sub-district satisfies, and the entry condition of sub-district CRS mode switch is according to activating UE quantity and UE type of service Combined Treatment in the sub-district.
Because the type of service in LTE has a variety of: as third generation partner program (the 3rdGeneration Partner Project, abbreviation) 9 kinds of qos class sign (QoSClass Identifier of 3GPP definition, be called for short QCI) classification, and the QCI kind of operator oneself definition, for the sake of simplicity, can practical business type the sub-district be divided into variable ratio business (Guaranteed Bit Rate is called for short GBR) and immutable ratio business (non-GBR) from the situation difference of scheduling Resources allocation.Suppose that the professional required Resources allocation weights of each variable ratio are w1, the variable ratio number of services is m1, the professional required Resources allocation weights of immutable ratio are w2, the quantity of immutable ratio business is m2, according to its type of service weighted sum, the professional required Resources allocation summation of the professional and immutable ratio of variable ratio is M, M=w1*m1+w2*m2, and the type of service weighted sum threshold value of the required Resources allocation summation of the sub-district of supposing is N.
Suppose that the sub-district is in normal mode, carve at a time that M＜N is arranged, and then the CRS mode switch sub-district by switching cell enters energy-saving mode.If the sub-district has been in energy-saving mode, carve at a time, M＞N is arranged, then the CRS pattern by switching cell switches to normal mode with the sub-district from energy-saving mode.
Suppose that the sub-district is in normal mode at this moment, then constantly at t1, if M＜N then starts timer T Save, if timer expiry, M＜N still, then the CRS pattern of switching cell is an energy-saving mode; As the not overtime M＞N that occurred of timing, then stop timer.If t2 at a time, M＞N, and this moment the sub-district the CRS pattern be energy-saving mode, start timer T Nor, if timer expiry, M＞N still, then the pattern of switching cell is a normal mode, above-mentioned timer is selectable, can adopt, and also can.
Perhaps, when the sub-district exists degree of depth energy-saving mode and shallow degree energy-saving mode, the resource of required distribution is in the 3rd interval or in the 4th interval in the sub-district, if the result who judges is in the 3rd interval, then starting energy-saving mode is degree of depth energy-saving mode, if the result who judges is in the 4th interval, then starting energy-saving mode is shallow degree energy-saving mode.Wherein, under the degree of depth energy-saving mode selected part number of sub-frames less than selected part number of sub-frames under the shallow degree energy-saving mode.Herein the 3rd interval and the 4th interval can be limited by two thresholdings.For example, can be second pre-conditioned described in the sub-district the required Resources allocation of state of activation UE comprise at least two thresholdings, start the sub-district according to the residing threshold range of the required Resources allocation of state of activation UE in the described sub-district and enter in various degree energy-saving mode.Promptly can set the required Resources allocation of state of activation UE in the sub-district less than a thresholding, then enter shallow degree energy-saving mode, if the required Resources allocation of state of activation UE then enters degree of depth energy-saving mode less than the b thresholding in the sub-district.In this case, also can adopt timer, perhaps not adopt timer.
Be understandable that the implementation of mode two can be so that the economize on electricity of system when the certain Resources allocation of needs, also can be realized in the sub-district, the prior art of comparing has enlarged the scope that energy-saving mode is used, and has further saved system energy consumption.
In addition, in judgement, adopt timer, can be under the required Resources allocation in sub-district keeps stable prerequisite in a period of time relatively, decision starts switching from the normal mode to the energy-saving mode or the switching from the energy-saving mode to the normal mode again, avoid the sub-district between normal mode and energy-saving mode, frequently to switch, further guaranteed the stability of system.
Mode three
Judge in the described sub-district whether state of activation UE telecommunication service quality and running time-frequency resource utilance satisfy the 3rd and pre-conditionedly determine whether starting the sub-district and enter energy-saving mode.
For example, less than the 3rd thresholding, and cell communication service quality determines whether starting the sub-district greater than the 4th thresholding and enters energy-saving mode by the running time-frequency resource utilance that judges whether to satisfy the sub-district.The 3rd pre-conditioned can be two thresholdings setting respectively at state of activation UE telecommunication service quality and running time-frequency resource utilance, the running time-frequency resource utilance of sub-district is less than the setting thresholding of its correspondence, and cell communication service quality then starts the sub-district and enters energy-saving mode greater than the setting thresholding of its correspondence.When the running time-frequency resource utilance of sub-district is not less than the setting thresholding of its correspondence, perhaps cell communication service quality does not satisfy the setting thresholding greater than its correspondence, does not then start the sub-district and enters energy-saving mode.
Perhaps, when the sub-district existed degree of depth energy-saving mode and shallow degree energy-saving mode, wherein, selected part number of sub-frames was less than selected part number of sub-frames under the shallow degree energy-saving mode under the degree of depth energy-saving mode.Judge that the running time-frequency resource utilance is in the 5th interval or in the 6th interval in the sub-district, if the result who judges is in the 5th interval, and the telecommunication service quality in the sub-district is greater than the 6th thresholding, then starting energy-saving mode is degree of depth energy-saving mode, if the result who judges is in described the 6th interval, and the telecommunication service quality in the sub-district is greater than the 6th thresholding, and then starting energy-saving mode is shallow degree energy-saving mode.
Concrete speech and, judge that the coupling the satisfied the 3rd of the total traffic of state of activation UE in the described sub-district and service quality satisfaction and schedulable running time-frequency resource is pre-conditioned.Be sub-district CRS mode switch entry condition according to " total traffic of sub-district and service quality (Quality of Service, be called for short QoS) satisfaction " together the match condition of " schedulable running time-frequency resource utilization rate " start the switching of CRS pattern.Suppose at moment t1, the total traffic carrying capacity in sub-district is very low, cause the utilization rate of sub-district running time-frequency resource very low, the predefined thresholding N% in sub-district, this moment, the CRS pattern of switching cell was an energy-saving mode, if t2 at a time, the total traffic carrying capacity in sub-district raises, and the resource utilization of predefined N% can't satisfy the QoS of UE, and for example the GBR speed of UE can't guarantee etc., and this moment, the CRS pattern of sub-district was an energy-saving mode, and then the pattern of switching cell is a normal mode.When cell load is very light, the bursty data of small number of users may cause the sudden change of cell load, for fear of near N%, frequently switching back and forth, can be by the certain sluggishness of definition, promptly at normal mode when energy-saving mode is switched, Rule of judgment is＜N%-delta%, in energy-saving mode when normal mode switches, Rule of judgment＞N%+delta%.The cell business volume load information can also be carried out the filtering of certain filter factor, prevent the sudden change of load information.In this entry condition, also can adopt and add the method that timer is judged.
Be understandable that the implementation of mode three can be so that the economize on electricity of system when satisfying the QoS of UE, also can be realized in the sub-district, the prior art of comparing has enlarged the scope that energy-saving mode is used, and has further saved system energy consumption.
In addition, the certain sluggishness of definition in judgement avoids the sub-district frequently to switch between normal mode and energy-saving mode, has further guaranteed the stability of system.
Mode four
Be full of by the average throughput of judging the sub-district and not do not satisfy the 4th pre-conditioned decision and whether start the sub-district and enter energy-saving mode, the 4th pre-conditioned can be a predefined thresholding, the required Resources allocation of state of activation UE then starts the sub-district and enters energy-saving mode less than this thresholding in the sub-district; The required Resources allocation of state of activation UE is not less than this thresholding in the sub-district, does not then start the sub-district and enters energy-saving mode.
Perhaps, when the sub-district exists degree of depth energy-saving mode and shallow degree energy-saving mode, in average throughput in the judgement sub-district is between SECTOR-SEVEN or between Section Eight, if the result who judges be between SECTOR-SEVEN in, then starting energy-saving mode is degree of depth energy-saving mode, if the result who judges be between Section Eight in, then starting energy-saving mode is shallow degree energy-saving mode.Wherein, under the degree of depth energy-saving mode selected part number of sub-frames less than selected part number of sub-frames under the shallow degree energy-saving mode.
Perhaps, also can determine between SECTOR-SEVEN herein and between Section Eight by two thresholdings, for example the 4th pre-conditioned described in the average throughput of sub-district comprise at least two thresholdings, start the sub-district according to the residing threshold range of the average throughput of described sub-district and enter in various degree energy-saving mode.The average throughput that promptly can set the sub-district then enters shallow degree energy-saving mode less than first thresholding, if the average throughput of sub-district then enters degree of depth energy-saving mode less than second thresholding.
Judge that described sub-district is pre-conditioned at the average throughput the satisfied the 4th of Preset Time, promptly start the switching of CRS pattern by the variation of sub-district average throughput, at sub-district average throughput＜N, perhaps＜(N is a mode switch throughput thresholding during N-delta, unit is Mbit/s), switching cell CRS pattern is an energy-saving mode, on the contrary at sub-district average throughput＞N, perhaps＞during N-delta, switching cell CRS pattern is a normal mode.The sub-district average throughput that statistics can also be obtained carries out the filtering of certain filter factor, prevents the sudden change of throughput information.In this entry condition, also can adopt and add the method that timer is judged.
Be understandable that the implementation of mode four can be so that the economize on electricity of system under certain average throughput situation, also can be realized in the sub-district, the prior art of comparing has enlarged the scope that energy-saving mode is used, and has further saved system energy consumption.
In addition, the certain sluggishness of definition in judgement avoids the sub-district frequently to switch between normal mode and energy-saving mode, has further guaranteed the stability of system.
Mode five
Whether by the power down switch of judging the sub-district webmaster decision is set starts the sub-district and enters energy-saving mode.Enter power save mode when the power down switch of sub-district webmaster is provided with the decision sub-district, can divide subframe, and on the part subframe of this selection, send public reference signal and start the sub-district and be in energy-saving mode by selection portion.
Perhaps, when the sub-district exists degree of depth energy-saving mode and shallow degree energy-saving mode, selected part number of sub-frames also can enter energy-saving mode in various degree by the number startup sub-district that changes selected part subframe less than selected part number of sub-frames under the shallow degree energy-saving mode under the degree of depth energy-saving mode.
The implementation of mode five can be so that the energy-conservation of system according to energy-conservation needs, be realized in the sub-district, thereby reduces the energy consumption of system.
Mode six
By judging that the residing electrical network in sub-district belongs to the power emergency state and determines that whether starting the sub-district enters energy-saving mode.Residing grid power belongs to emergency rating when the sub-district, can divide subframe by selection portion, and transmission public reference signal startup sub-district is in energy-saving mode on the part subframe of this selection.
Perhaps, when the sub-district exists degree of depth energy-saving mode and shallow degree energy-saving mode, selected part number of sub-frames also can enter energy-saving mode in various degree by the number startup sub-district that changes selected part subframe less than selected part number of sub-frames under the shallow degree energy-saving mode under the degree of depth energy-saving mode.
The implementation of mode six can be so that the energy-conservation of system according to the needs of power emergency state, be realized in the sub-district, thereby reduces the energy consumption of system.
Be understandable that not only can there be the energy-saving mode that starts under the situation of state of activation UE at the sub-district in the embodiment of the invention in the sub-district, also can in the sub-district, have the energy-saving mode that starts under the situation of state of activation UE at the sub-district.And in the sub-district, exist under the situation of state of activation UE, judging that the method that starts energy-saving mode is not limited to above-mentioned six kinds, can also be that other any needs that it may occur to persons skilled in the art that start the situation that the sub-district enters energy-saving mode or enters energy-saving mode in various degree.
Embodiment five
The cardinal principle flow process of fifth embodiment of the invention can be referring to first to fourth embodiment.And under energy-saving mode, communicate with UE in the sub-district and can comprise following a kind of or wherein several combination:
One, the state of activation UE under the energy-saving mode is carried out channel estimating.
Concrete, when having state of activation UE in the sub-district, the state of activation UE under the energy-saving mode is carried out channel estimating can be comprised: by measuring auxiliary synchronization channel the state of activation UE under the energy-saving mode is carried out channel estimating.Perhaps, carry out channel estimating by the subframe of measuring auxiliary synchronization channel and vicinity thereof.Perhaps, by the reference signal of measure portion subframe the state of activation UE under the energy-saving mode is carried out channel estimating.Perhaps, the state of activation UE under the energy-saving mode is carried out channel estimating, the contiguous subframe of subframe that this part subframe comprises the subframe that sends CRS or sends CRS by the reference signal of measuring auxiliary synchronization channel and part subframe.
Particularly, about carrying out channel estimating under the energy-saving mode:, and then carry out data demodulates because the original CRS that adopts carries out channel estimating.But under energy-saving mode, do not exist all the PRB resources on all subframes all to have CRS to send, so can adopt: auxiliary synchronization channel is measured replaced C RS and carried out channel estimating, perhaps part subframe CRS measures and replaces all CRS to carry out channel estimating; Perhaps auxiliary synchronization channel measurement and part subframe CRS replace all CRS to carry out channel estimating.
Concrete implementing method is exemplified below:
(1) the frequency domain restriction by scheduling improves accuracy of estimation
Because 6 Resource Block (Resource Block of auxiliary synchronization channel, abbreviation RB) auxiliary synchronization channel is arranged, the estimation that the RB of the physical down link sharing channel adjacent with these 6 RB (PDSCH:PhysicalDownlink Shared Channel is called for short PDSCH) can use auxiliary synchronization channel realizes demodulation.Like this, when reconciling this sub-district small number of users, can estimate to come demodulation, also can come demodulation by near the RB resource the auxiliary synchronization channel by using auxiliary synchronization channel.For this part RB, on any subframe on the time domain, can call.
(2) the time domain restriction by scheduling improves accuracy of estimation
Because under energy-saving mode, have at least a subframe to have CRS to send, so can at these subframe of CRS transmission be arranged by constrained dispatch in the time of dispatch user data, promptly at the enterprising row constraint of time domain, like this at these Transmission Time Intervals (Transmission Time Interval, be called for short TTI), all RB can call on the frequency domain, and the channel estimating quality on these subframes is suitable with normal RS the time.Simultaneously also can be near the subframe that has CRS to send the subframe invoke user, though this moment, these subframes did not have CRS to send, its CRS in abutting connection with subframe estimates that available using carry out demodulation.
Two, the state of activation UE under the energy-saving mode is carried out resource allocation
Concrete, when having state of activation UE in the sub-district, the state of activation UE under the energy-saving mode is carried out resource allocation can be comprised: distribute the Physical Resource Block of the center of housing estate at auxiliary synchronization channel place for state of activation UE.Perhaps, the contiguous Resource Block of center of housing estate Physical Resource Block of distributing the auxiliary synchronization channel place for state of activation UE.Perhaps, be distributed in the interior corresponding full range band available resource block of time period that pilot signal transmits for state of activation UE.
For some special business such as delay sensitive class business, this sentences IP phone (Voice Over Internet Protocol, be called for short VOIP) be example, because this type of professional non-self-adapting that adopts mostly retransmits and semi-persistent scheduling, if the scheduling of time domain restriction can't be satisfied the requirement of this type of business to time delay, can retrain the scheduling of this type of business is dispatched on 6 RB of center of housing estate, retransmit and also on these 6 RB, dispatch.Promptly, can use the schedule constraints method of frequency domain restriction to satisfy the QoS of survice requirement at delay sensitive class business.
Three, the state of activation UE under the energy-saving mode being carried out mobile management measures
Concrete, when having state of activation UE in the sub-district, the state of activation UE under the energy-saving mode is carried out mobile management measure and can comprise: measure by auxiliary synchronization channel state of activation UE is carried out the mobile management measurement.Perhaps, by the measurement of part subframe state of activation UE being carried out mobile management measures.Perhaps, by auxiliary synchronization channel measurement and the measurement of part subframe state of activation UE is carried out mobile management and measure, this part subframe comprises that measurement sends the subframe of CRS or the contiguous subframe of subframe of measurement transmission CRS.
Four, the state of activation UE under the energy-saving mode is retransmitted resource allocation
Concrete, when having state of activation UE in the sub-district, state of activation UE under the energy-saving mode is retransmitted resource allocation to be comprised: the distribution of the re-transmission resource that self adaptation retransmits is with just the biography distribution method is identical, at the Physical Resource Block of non-center of housing estate the subframe that sends CRS is arranged if re-transmission just passes resource to state of activation UE non-self-adapting, the subframe that then sends CRS need satisfy the restriction of re-transmission period.
Particularly, mix and retransmit (Hybrid Automatic Repeat reQuest automatically, abbreviation HARQ) cycle that retransmits is fixed as 8ms, i.e. 8 Transmission Time Interval (Transmission TimeInterval, be called for short TTI), so must consider the existence of CRS transmission subframe to the resource allocation of HARQ re-transmission.When frequency domain dispatching limited, when promptly scheduling resource was 6 RB in center, retransmitted resource to HARQ and do not have problems this moment.And when adopting during the domain scheduling restriction, the distribution of HARQ resource must be considered the existence of CRS transmission subframe, need satisfy subframe that the CRS transmission is arranged or the constraint of 6 RB in center so self adaptation retransmits the HARQ resource allocation.The first biography resource that non-self-adapting retransmits also must be assigned as the subframe of CRS transmission or the constraint of 6 RB in center, and per 8 TTI are satisfied in the configuration that perhaps has CRS to transmit subframe all CRS transmission subframe.
Five, the beep-page message resource under the energy-saving mode is distributed
When there is state of activation UE in the sub-district, perhaps there is not state of activation UE, the beep-page message resource under the energy-saving mode is distributed specifically and can be comprised: with the Physical Resource Block of the beep-page message resource allocation under the energy-saving mode at the center of housing estate at auxiliary synchronization channel place.Perhaps, the Resource Block that the center of housing estate Physical Resource Block of the beep-page message resource allocation under the energy-saving mode at the auxiliary synchronization channel place closed on.Perhaps, will be in the time period that has pilot signal to transmit on the corresponding full range band available resource block to the beep-page message resource allocation under the energy-saving mode.
Particularly, about under energy-saving mode, the beep-page message resource being distributed, when in the sub-district paging being arranged, by the frequency domain restriction raising accuracy of estimation of scheduling, with the Physical Resource Block of beep-page message resource allocation at the center of housing estate at auxiliary synchronization channel place.Because 6 Resource Block (Resource Block of auxiliary synchronization channel, abbreviation RB) auxiliary synchronization channel is arranged, the physical down link sharing channel adjacent (PDSCH:Physical Downlink Shared Channel with these 6 RB, being called for short PDSCH) the RB estimation that can use auxiliary synchronization channel realizes demodulation, when calling this sub-district small number of users like this, use auxiliary synchronization channel to estimate to come demodulation, so, the frequency domain scope that can call is exactly near the RB resource 6 RB auxiliary synchronization channels, for this part RB, on any subframe on the time domain, can call.
The also Resource Block that the center of housing estate Physical Resource Block of beep-page message resource allocation at the auxiliary synchronization channel place can be closed on.To this choice criteria of closing on Resource Block is to utilize this to close on can satisfy the Qos requirement, can use auxiliary synchronization channel and carry out channel estimating.Also can distribute in full range band data available resource block with the beep-page message resource allocation constantly in the subframe that has pilot signal to transmit.If have CRS to send in section sometime, then can the beep-page message scheduling at this moment of this time period between on the Resource Block in the section.Utilize CRS to carry out data demodulates as channel estimating.In a word, can be with the Physical Resource Block of beep-page message resource allocation at the center of housing estate at auxiliary synchronization channel place; The perhaps Resource Block that the center of housing estate Physical Resource Block of beep-page message resource allocation at the auxiliary synchronization channel place closed on; Perhaps on the full range band available resource block with beep-page message resource allocation correspondence in the time period that has pilot signal to transmit.
The technical scheme of the embodiment of the invention can make system carry out the state of activation UE under the energy-saving mode is carried out channel estimating, the state of activation UE under the energy-saving mode is carried out state of activation UE under resource allocation, the energy-saving mode retransmits resource allocation, when the state of activation UE under the energy-saving mode is carried out mobile management and measures, has state of activation UE in the sub-district or do not have state of activation UE the beep-page message resource under the energy-saving mode is distributed under power save mode.
Embodiment six
The cardinal principle flow process of sixth embodiment of the invention can be referring to first to fourth embodiment.And under energy-saving mode, can there be state of activation UE in this sub-district, perhaps has state of activation UE.Can send to described adjacent base station by information interaction with start the information of energy-saving mode at the sub-district with adjacent base station, and/or, send to UE in the sub-district by air interface.Present embodiment will be described this.
When the sub-district enters energy-saving mode, on the one hand, the CRS pattern information of sub-district can be notified user's (comprising excited users and/or Idle state user) of this sub-district, on the other hand, can be with the CRS pattern information notice adjacent base station (can be understood as the notice adjacent area logically) of oneself, the user of all services of the CRS pattern of sub-district notice neighbor base station so that adjacent base station will economize on electricity.The adjacent area can not send energy-conservation information to the user yet, and these information are used for the management of abutting subdistrict, can optimize some RRM (radio resource manage RRM) algorithms such as switching, load balancing, interference coordination.
The energy-saving mode of sub-district can be notified to this community user by system broadcast message, is notified to the adjacent area by X2 interface.The community user of adjacent area can be further given by system broadcast message or Radio Resource control (Radio Resource Control is called for short RRC) reallocation message or other RRC message informings in the adjacent area.
Concrete, for example, after cell pattern switches to energy-saving mode, broadcast cell CRS pattern is an energy-saving mode in system broadcast information, simultaneously by X2 signaling interface notice adjacent area, it is after being in energy-saving mode that the adjacent area obtains this sub-district, by system broadcasts or RRC reallocation message or newly-increased RRC message or other RRC message, tells that this sub-district of UE in the own sub-district is in energy-saving mode.
And the pattern of working as this sub-district is a normal mode, and broadcast cell CRS pattern is a normal mode in system broadcast information simultaneously, simultaneously by X2 interface notice adjacent area.It is after being in normal mode that abutting subdistrict obtains this sub-district, by system broadcasts or RRC reallocation message or newly-increased RRC message or other RRC message, tells that this sub-district of UE in the own sub-district is in normal mode.
Perhaps, when adopting the energy-saving mode of two kinds of levels, after cell pattern switched to shallow degree energy-saving mode, broadcast cell CRS pattern was shallow degree energy-saving mode in system broadcast information, by X2 signaling interface notice neighbor base station, perhaps the S1 interface is transmitted to neighbor base station simultaneously.It is after being in shallow degree energy-saving mode that abutting subdistrict obtains this sub-district, by system broadcasts or RRC reallocation message or newly-increased RRC message or other RRC message, tells that this sub-district of UE in the own sub-district is in shallow degree energy-saving mode.When judging that on this basis after cell pattern switched to degree of depth energy-saving mode, broadcast cell CRS pattern was a degree of depth energy-saving mode in system broadcast information, simultaneously by X2 signaling interface notice adjacent area, as base station configuration updating information.It is after being in degree of depth energy-saving mode that abutting subdistrict obtains this sub-district, by system broadcasts or RRC reallocation message or newly-increased RRC message or other RRC message, tells that this sub-district of UE in the own sub-district is in degree of depth energy-saving mode.
If but cell status is shallow degree energy-saving mode by the pattern of degree of depth energy-saving mode switching cell, then simultaneously in system broadcast information broadcast cell CRS pattern be shallow degree energy-saving mode, simultaneously by X2 interface notice adjacent area.It is after being in shallow degree energy-saving mode that abutting subdistrict obtains this sub-district, by system broadcasts or RRC reallocation message or newly-increased RRC message or other RRC message, tells that this sub-district of UE in the own sub-district is in shallow degree energy-saving mode.
If the sub-district is a normal mode from shallow degree economize on electricity cross cutting changing district again, broadcast cell CRS pattern is a normal mode in system broadcast information simultaneously, simultaneously by X2 interface notice adjacent area.It is after being in normal mode that abutting subdistrict obtains this sub-district, by system broadcasts or RRC reallocation message or newly-increased RRC message or other RRC message, tells that this sub-district of UE in the own sub-district is in normal mode.
As long as the CRS pattern of sub-district changes, can notify the adjacent area.For the mobility performance (comprising normal switching and sub-district gravity treatment) that does not influence the adjacent area user, need be with the CRS energy-saving mode information notice adjacent area of this sub-district, and (for example the CRS normal mode switches to the CRS energy-saving mode, and the CRS energy-saving mode switches to the CRS normal mode) also will in time notify the adjacent area when the CRS energy-saving mode changes.
CRS energy-saving mode information comprises following content:
CRS pattern, i.e. CRS energy-saving mode or CRS normal mode.The measurement of CRS energy-saving mode adjacent area is only adopted under the scene that auxiliary synchronization channel measure to estimate at UE, between different base station, transmitted this information and can satisfy the adjacent area user and measure needs.
If agreement regulation energy-saving mode specifically sends CRS in which subframe, whether only transmit between the base station so energy-saving mode or dark, shallow, normal mode is also passable, need not transmit which subframe again and send CRS.Estimate if the measurement of the wireless signal of adjacent area adopts part subframe CRS to measure, and agreement do not stipulate employed subframe under the concrete energy-saving mode, so need transmit between the different base station use for the CRS energy-saving mode under the subframe numbers that sends of CRS.
The transfer approach of CRS energy-saving mode information between the base station comprises following several situation, is not limited to following method:
One, use X2 interface more new technological process be in energy-saving mode and CRS message as subsidiary this sub-district of: base station configuration updating flow process (ENBCONFIGURATION UPDATE) as energy-saving mode.
It is few when if two cell initials are set up because of traffic carrying capacity, just adopt the CRS energy-saving mode at the beginning of the foundation, also need in foundation response (SETUP RESPONSE) message of setting up request message (SETUP REQUEST) or X2 interface of X2 interface, carry the CRS energy-saving mode information of sub-district.
Three, when UE switches, can also notify UE about sub-district CRS pattern by the method that special-purpose hand off signaling transmits.Based on the switching of X2 interface the time, target BS can be admitted to give source base station with the indication of sub-district CRS pattern dominance in the message (HANDOVER REQUEST ACKNOWLEDGE) in the request of transferring, and the source end group stands in the RRC connection reconfiguration message (switching command) and gives UE with its indication then.UE carries out channel estimating according to this indication and the version ability of oneself in subsequent operation.Target BS also can be admitted to give source base station with the indication of sub-district CRS pattern recessiveness in the message (HANDOVERREQUEST ACKNOWLEDG) in the request of transferring, being about to sub-district CRS pattern is included in the request of transfer and admits " target BS is to the source base station transparent vessel " (Target eNB To Source eNB Transparent Container) in the message, source base station is not resolved the content in this container, and it will be stood in RRC by the source end group and connect in the reconfiguration message (switching command) transparent being transferred to and switch UE.
Four, based on the switching of S1 core network interface the time, target BS message admits to give mobile management module (MobilityManagement Entity with the indication of sub-district CRS pattern dominance in the message in the request of transferring, be called for short MME), MME (HANDOVERCOMMAND) dominance in transferring order is indicated to end group station, source then, and the source end group stands in the RRC connection reconfiguration message (switching command) and gives UE with its indication then.UE carries out channel estimating according to this indication and the version ability of oneself in subsequent operation.Target BS also can be admitted to give MME with the indication of sub-district CRS pattern recessiveness among the HANDOVERREQUEST ACKNOWLEDG in the request of transferring, be about to sub-district CRS pattern and be included in the request of transfer and admit " target BS is to the source base station transparent vessel " Target To Source Transparent Container in the message, MME does not resolve the content in this container.But being included in " target BS is to the source base station transparent vessel " transferred in the order, it sends to source base station eNB.It will be stood in RRC by the source end group and connect in the reconfiguration message (switching command) transparent being transferred to and switch UE.
The technical scheme of the embodiment of the invention can make system power save mode be notified this community user and adjacent area under power save mode.

Embodiment ten
Tenth embodiment of the invention relates to a kind of communication equipment.This embodiment is on the basis based on any communication equipment of embodiment seven to embodiment nine, and judging unit and performance element carry out to judge and one of to carry out or its combination.
In the sub-district, do not have state of activation UE, can think and satisfy the condition that starts energy-saving mode, thereby startup is at the energy-saving mode of sub-district.In this case, can be understood as, whether exist state of activation UE to can be used as the Rule of judgment or the foundation of judging unit in the sub-district, in the sub-district, do not have state of activation UE, can think and satisfy the condition that starts energy-saving mode, performance element starts the energy-saving mode at the sub-district.
When having state of activation UE in the sub-district, can be divided into two kinds of situations:
Situation one:
Wherein, when the energy-saving mode of sub-district comprises a kind ofly, this judging unit and performance element carry out to judge and one of to carry out or its combination:
Judge whether state of activation UE quantity satisfies first condition in the sub-district, this first condition is: the quantity of state of activation UE is less than first thresholding in the sub-district, if the result who judges is less than first thresholding, then performance element starts energy-saving mode, if the result who judges is more than or equal to first thresholding, then performance element does not start energy-saving mode, and state of activation UE quantity equals first thresholding and makes performance element start energy-saving mode in the sub-district herein, still do not start energy-saving mode, can be provided with as required, and can be set to start or do not start energy-saving mode when judged result equals to set thresholding just in these are judged below as required.
Whether the resource of judging the required distribution of state of activation UE in the sub-district satisfies second condition, this second condition is: the resource of required distribution is less than second thresholding in the sub-district, if the result who judges is less than second thresholding, then performance element starts energy-saving mode, if the result who judges is more than or equal to second thresholding, then performance element does not start energy-saving mode.
Judge whether state of activation UE telecommunication service quality and running time-frequency resource utilance satisfy the 3rd condition in the sub-district, the 3rd condition is: the running time-frequency resource utilance of sub-district is less than the 3rd thresholding, and cell communication service quality is greater than the 4th thresholding, if the result who judges is that the running time-frequency resource utilance is less than the 3rd thresholding, and cell communication service quality is greater than the 4th thresholding, then performance element starts energy-saving mode, if the running time-frequency resource utilance is more than or equal to the 3rd thresholding among the result who judges, perhaps cell communication service quality is smaller or equal to the 4th thresholding, and then performance element does not start energy-saving mode.
Judge whether the sub-district satisfies the 4th condition at the average throughput of Preset Time, the 4th condition is: the average throughput of sub-district is less than the 5th thresholding, if the result who judges is less than the 5th thresholding, then performance element starts energy-saving mode, if the result who judges is more than or equal to the 5th thresholding, then performance element does not start energy-saving mode.This judging unit can also judge whether the power down switch of sub-district webmaster is provided with the sub-district and enters power save mode, judges that perhaps the residing electrical network in sub-district belongs to the power emergency state.
Situation two:
Perhaps, energy-saving mode when the sub-district comprises degree of depth energy-saving mode and shallow degree energy-saving mode, selected part number of sub-frames is less than selected part number of sub-frames under the shallow degree energy-saving mode under the degree of depth energy-saving mode, and judging unit and performance element carry out to judge and one of to carry out or its combination:
The quantity of state of activation UE is in first interval or in second interval in the judgment unit judges sub-district, if the result who judges is in first interval, then performance element startup energy-saving mode is a degree of depth energy-saving mode, if the result who judges is in second interval, then performance element startup energy-saving mode is shallow degree energy-saving mode, if neither in first interval, not in second interval, then performance element does not start energy-saving mode to the result who judges yet.
The resource of required distribution is in the 3rd interval or in the 4th interval in the judgment unit judges sub-district, if the result who judges is in the 3rd interval, then performance element startup energy-saving mode is a degree of depth energy-saving mode, if the result who judges is in the 4th interval, then to start described energy-saving mode be shallow degree energy-saving mode to performance element, if neither in the 3rd interval, not in the 4th interval, then performance element does not start energy-saving mode to the result who judges yet.
The running time-frequency resource utilance is in the 5th interval or in the 6th interval in the judgment unit judges sub-district, if the result who judges is in described the 5th interval, and the telecommunication service quality in the sub-district is greater than the 6th thresholding, then performance element startup energy-saving mode is a degree of depth energy-saving mode, if the result who judges is in the 6th interval, and the telecommunication service quality in the sub-district is greater than the 6th thresholding, then performance element startup energy-saving mode is shallow degree energy-saving mode, if the result who judges is neither in the 5th interval, not in the 6th interval, then performance element does not start energy-saving mode yet.
In average throughput in the judgment unit judges sub-district is between SECTOR-SEVEN or between Section Eight, if the result who judges be between described SECTOR-SEVEN in, then performance element startup energy-saving mode is a degree of depth energy-saving mode, if the result who judges be between Section Eight in, then performance element startup energy-saving mode is shallow degree energy-saving mode, in the result who judges was neither between Section Eight, not in the 9th interval, then performance element did not start energy-saving mode yet.
The technical scheme of the embodiment of the invention, can be so that energy-saving mode be used in the sub-district when one of following situation or its combination: (comprise that not only state of activation UE is zero situation in the sub-district, also comprise existing state of activation UE and state of activation UE quantity satisfying pre-conditioned situation when having the activated state subscriber equipment some scopes in.), or the sub-district is when the certain Resources allocation of needs, or the sub-district is when satisfying the QoS of UE, or the sub-district is under certain average throughput situation, or according to energy-conservation needs, or according to the economize on electricity of realization system under the power emergency state, native system is not limited only to as above realizing the energy-conservation of system under the situation, the prior art of comparing has enlarged the scope that energy-saving mode is used, and has further saved system energy consumption.
