Description
Technical field
The present invention relates to the communications field, in particular to a kind of subscriber equipment power consumption, power consumption configuration parameter processing method and device.
Background technology
In existing broadband wireless communication system, in order to control user terminal (User Equipment, referred to as UE) power consumption, two kinds of typical mechanism have been used, a kind of is discontinuous reception (Discontinuous Reception, referred to as DRX) mechanism, another kind is that the Radio Resource of network controls is controlled (Radio Resource Control is referred to as RRC) Connection Release.
The DRX discontinuous reception refers to terminal and stops monitoring to Physical Downlink Control Channel (Physical Downlink Control Channel is referred to as PDCCH) in following period of time.DRX divides two kinds: a kind of is idle (IDLE) DRX, is in discontinuous reception under the IDLE state when terminal exactly; When being in the IDLE state, do not had radio resource control to connect and user's specific resource, so IDLE DRX is mainly used in monitored call channel and broadcast channel, as long as define the fixing cycle, just can reaches the purpose of discontinuous reception; But, if the terminal monitoring user data channel must be introduced into connection status from the IDLE state.Another kind is exactly to activate (Active) DRX, be exactly the DRX of end under RRC connection (RRC-CONNECTED) state, can the optimization system resource distribution, the more important thing is and to save power consumption of terminal, do not need just can reach the purpose of saving power consumption of terminal by allowing terminal enter into RRC free time (RRC_IDLE) state, for example, always there is a period of time in some non real-time application (web-browsing, instant messaging etc.), terminal does not need ceaselessly to monitor downlink data, also do not need to carry out relevant treatment, DRX just can be applied in such scene.In addition, owing to existing RRC to connect under Active DRX state, therefore, it is very fast that terminal will forward the speed of the state of monitoring downlink data to.
Have some timers in DRX, some timers are described below, wherein all time all is based on subframe, namely take ms as unit):
1, continuous firing timer (On Duration Timer)
Terminal is kept the time that wakes at every turn after DRX wakes up, terminal can search PDCCH in the period at this section.
2, stop timer (Inactivity Timer)
Terminal is when waking, mixed automatic retransfer request (Hybrid Automatic Repeat Reqest successfully decodes at every turn, referred to as HARQ) time of keeping Active after the PDCCH of initialization, namely when PDCCH that terminal is received indication be the initial transmission (rather than re-transmission) of a UL/DL after, the time that need to keep Active, the time that terminal is successfully decoded when waking at every turn and kept Active after the PDCCH of HARQ initialization.
3, the rear total work timing device (Active Timer) of once waking up
Terminal is waken up the total time that rear maintenance wakes from DRX, at this moment between section, terminal monitoring PDCCH, comprising that all cause terminal to be in the state of Active, for example, can be that DRX cycle begins " On Duration ", or receive the PDCCH of initial transmission, or monitor and retransmit etc.
If configured DRX, Active Time comprises the following time so: the time of On Duraion Timer, Inactivity Timer, DRX retransmission timer (DRX Retransmission Timer) and the congested solution timer of MAC layer (MAC Contention Resolution Timer) operation; Or, there is dispatch request (SR, Scheduling Req terminal set) to send to PUCCH, and is in the state (namely this dispatch request does not also satisfy) of hang-up; Or, there is uplink authorization in the HARQ of a hang-up, and in the harq buffer district of correspondence, data is arranged; Or, after non-competing random access, successfully receive accidental access response message, should have this moment PDCCH to send to new transmission of terminal indication, but this PDCCH also do not receive, this moment, terminal still must be in the Active state.
4, HARQ comes and goes timer (HARQ RTT Timer)
Be exactly that terminal does not need for the time being to comprehend re-transmission and can when arrive the earliest the minimum interval time that the descending re-transmission of terminal expection (DL Retransmission) arrives, as long as this timer expiry, terminal will be in the state that wakes.
5、DRX Retransmission Timer
The terminal expection receives the time of DL Retransmission, needs exactly to accept so much time descending re-transmission.
6, DRX length of the cycle (DRX Cycle length)
In case DRX Cycle length configuration/reconfiguration just immobilizes, and can not change greater than On Duration because of Active Time.
The implementation of existing DRX mainly comprises: if use short DRX cycle, check whether current subframe satisfies formula: [(SFN*10)+subframe number] modulo (short DRX Cycle)=(DRX StartOffset) modulo (short DRX Cycle); If use long DRX cycle, check whether current subframe satisfies formula: [(SFN*10)+subframe number] modulo (long DRX Cycle)=DRX StartOffset; When two top conditions satisfy one of them, so just start On Duration Timer, this moment, terminal began to monitor PDCCH.When the shortest time that this subframe HARQ RTT Timer(expectation is retransmitted) overtime, retransmit and just might arrive, if at this moment have data (the namely data receiver of the front failure of successfully decoded or not for the soft buffering area of HARQ process, need data re-transmission), just start DRX Retransmission Timer and begin to monitor the relevant data of PDCCH re-transmission.If receive DRX MAC control information unit, just mean that eNB requires terminal to enter sleep state, at this moment will stop On Duration Timer and DRX Inactivity Timer, but can't stop being used for requiring terminal to continue to monitor the content that retransmits with retransmitting relevant timer.Overtime or when receiving DRX MAC control information unit as DRX Inactivity Timer, if configured short DRX cycle, start so or restart DRX shortCycle Timer, use short DRX cycle; Otherwise; Use long DRX cycle; If DRX short Cycle Timer is overtime, use so long DRX cycle.
The starting point that two-stage DRX Cycle is set is to think that a rear horse back of data transmission procedure end of terminal has the possibility of transfer of data larger again, therefore a short DRX cycle is set deals with this probability, never data will be transmitted in several short DRX cycles, illustrate that this data transfer completes really, can enter the deep sleep state, the long and short cycle cooperation can reach better DRX effect like this.
Above-mentioned is that in the DRX mechanism of the explanation as an example of the LTE system example, definition and the DRX of different Ti mer carries out flow process.DRX mechanism also can be applied in other system, for example, universal mobile telecommunications system (Universal Mobile Telecommunications System, referred to as UMTS), global system for mobile communications (Global System of Mobile communication, referred to as GSM) etc., concrete execution details is slightly variant, and flow process is similar substantially.
The RRC Connection Release of network controls refers to, network side sends rule by the data of sense terminals, prediction terminal (timer RRC inactivity timer that network side is default within follow-up a period of time, also referred to as RRC release timer) if there is no transfer of data, network side can discharge the connection of eating dishes without rice or wine of terminal, to discharge resource, because need not to keep the overhead channel of eating dishes without rice or wine, terminal sends simultaneously, so can play the effect that reduces the terminal power consumption.
Along with the universal and intelligence software of smart mobile phone, the variation of application, the optimization demand of terminal power consumption is more and more become a problem of present needs attention.above-mentioned two kinds of electricity-saving mechanisms are owing to being to decide its parameter configuration by network side, usually for dissimilar, different brands, what the terminal of different hardware configurations adopted is all identical parameter configuration strategy, from network side, saving power for terminal is only the strategy that a suboptimum is considered, the efficient of the normally system that network side is preferentially guaranteed and the user of terminal impression, for example, transmission delay, throughput, signaling consumption etc., and the indexs such as transmission delay and throughput have quality of service requirement (Quality ofService in existing standard, referred to as Qos) delimit grade, network side can decide with reference to the regulation of QoS grade how the dispatch network resource satisfies user's impression, network side also can be indicated and control by the S1 interface by core net the control dynamics of signaling consumption.But network side does not have reference frame for the requirement of saving power for terminal, therefore when determining DRX parameter and RRC thresholding release time, network side can't configure DRX parameter and RRC thresholding release time according to the strategy of deflection power saving effect, just can not guarantee that also terminal has power saving effect preferably.
Therefore, use the discontinuous reception DRX mechanism of existing control terminal power consumption in correlation technique, and the radio resource control RRC Connection Release of network controls mechanism, terminal power saving effect preferably can not be guaranteed.

Need to prove, the power consumption situation of this UE can comprise following one or more: whether the UE dump energy reaches or lower than default ratio; The dump energy of UE.Wherein, whether this UE dump energy reaches or lower than default ratio, default ratio wherein can be to be configured to UE by network side, or arranged in advance by network side and UE; In addition, network side to the mode of UE configuration can be: control (Radio Resource Control by Radio Resource, referred to as RRC) signaling, perhaps by media access control layer control unit (MediaAccess Control layer Control Element is referred to as MAC CE) configuration.
It is following one or a combination set of that the requirement to the power saving strategy of UE also can comprise: whether UE belongs to the equipment that low power consumption is had higher requirements, and perhaps the device attribute of UE has the requirement of what grade to low power consumption; Whether UE is moving the business that low power consumption is had higher requirements, and perhaps the business of UE operation has the requirement of what grade to low power consumption; Whether UE is in the class requirement not high business of operation to user's impression; UE tends to low power consumption or the high-quality user's impression of intended to ensure, and perhaps UE has the requirement of what grade to low power consumption; Terminal can also be some other oneself requirements of terminal to the requirement of power saving strategy, so long as the requirement relevant with power consumption can be used as be terminal to the requirement of power saving strategy, terminal is not given an example one by one to the requirement of power saving strategy at this.
UE sends to the mode of network side also can be multiple the power saving demand information, for example, can adopt one of following methods:
Send by the RRC signaling, the mode that sends by the RRC signaling can adopt following two kinds of processing modes: the RRC signaling of (1) newly-built special use, be used for sending the information of application layer traffic aided, that is, the RRC signaling of this newly-built special use is specifically designed to this power saving demand information of carrying; (2) add the information of application layer traffic aided in existing RRC signaling, namely by add the power saving demand information in existing RRC signaling, then send this power saving demand information by the mode that sends existing RRC signaling.
Send by MAC CE, namely carry this power saving demand information in the configuration information of MAC CE configuration, send this power saving demand information by the configuration information that sends MAC CE configuration.
Terminal power consumption management method in above-described embodiment and preferred implementation, for network side, network side can operate as follows after receiving the power saving demand information of UE transmission: (1) network side does not change any wireless parameter configuration of this UE; (2) network side according to above-mentioned power saving demand information, carries out corresponding wireless parameter and carries out reprovision, if this wireless parameter need be informed UE, this wireless parameter that will reshuffle of network side sends to UE.Need to prove, the network element of realizing above-mentioned functions in above-mentioned network side can be the base station, for example, for Long Term Evolution (Long Term Evolution, referred to as LTE) system, can be evolved NodeB(evolved NodeB, referred to as eNodeB), and for universal mobile telecommunications system (Universal Mobile Telecommunications System, referred to as UMTS), concerning the UMTS system, can refer to radio network controller (Radio Network Controller is referred to as RNC).The below describes as an example of the LTE system example, and the following example and preferred implementation also go for the UMTS system fully certainly.
UE sends to network side (can be the evolved base station of LTE system) with the power saving demand information in the present embodiment, and this power saving demand information represents that the power consumption situation of UE and/or UE are to the requirement of power saving strategy.In the power saving demand information that the below sends to network side for UE, the power consumption situation (being the power consumption state) of included UE and UE describe respectively the requirement of power saving strategy.
1, the power consumption situation of UE.
The power consumption situation of this UE can comprise following one or more: whether the UE dump energy reaches or lower than default ratio; The dump energy of UE.
Wherein, whether the UE dump energy reaches or lower than default ratio, default ratio can be to be configured to UE by network side, is perhaps arranged in advance by network side and UE.For example: network side and UE agreement, when the UE dump energy reaches or lower than 20% the time, UE sends indication information to the base station, this indication information can be the designator of 1bit, 1 represents that the UE dump energy reaches or lower than 20%; Otherwise be 0.
Wherein, network side to the mode of the default dump energy ratio of UE configuration can be: by down link RRC signaling, perhaps by MAC CE) configuration;
For example: network side can newly-built down link RRC signaling or MAC CE be exclusively used in the described default dump energy ratio that sends, perhaps in existing down link RRC signaling (for example, RRC Connection Reconfiguration(RRC connects reconfiguration message), RRC Connection Reestablishment(RRC connection reconstruction message), RRC Connection Setup(RRC connect set up message)) in set up new information unit (Information Element is referred to as IE) and carry.
Certainly, UE also can report the dump energy of oneself, the wireless parameter that the base station can determine how to configure this UE according to the size of UE dump energy (namely, the power consumption configuration parameter of above-mentioned indication, wherein, need to prove, this power consumption configuration parameter be exactly in fact network side be the wireless parameter of user terminal configuration, only the power consumption that can characterize user's request of this parameter requires information).
Network side and UE can arrange to come corresponding different UE dump energy with different identification, for example, can adopt the mode that reports as shown in table 1 below:
Table 1
| Sign | The UE dump energy |
| 0 | 80% |
| 1 | 50% |
| 2 | 20% |
| 3 | 5% |
When the UE dump energy met the numerical value of certain row in upper table, UE can report the above-mentioned sign corresponding with this row.More directly, UE also can not adopt the form of sign, directly reports concrete dump energy numerical value.
2, the requirement of UE to the power saving strategy
This UE can comprise following one or a combination set of to the requirement of power saving strategy:
(1) whether UE belongs to the equipment that low power consumption is had higher requirements, and perhaps the device attribute of UE has the requirement of what grade to low power consumption;
