An important issue in EDDA is power consumption problem.At present, suitable discontinuous reception (DRX) parameter being set is very useful mechanism for the battery power consumption of saving user equipment (UE).Use is applicable to hang down the DRX of real-time, and for example long period DRX can reduce the power consumption of UE effectively, and while such as the cycle as DRX, growing to 640ms, the power consumption of UE can reach the level of power consumption of idle pulley.By selecting suitable DRX parameter, during parameters such as DRX cycle, ON time, inertia timer duration, existing DRX mechanism can be saved the power consumption of UE effectively, so crucial problem just is the DRX parameter that How to choose is suitable.
In meeting before, some have been proposed for carrying out the motion of DRX parameter setting.Suggestion in the industry is the user equipment (UE) for the business of only having powerful connections, and make the power of connection status close with the idle state.Therefore, only the have powerful connections subscriber equipment of business should arrange long DRX.But, in existing standard, base station can't judge the subscriber equipment business of whether only having powerful connections.In the standardization motion, the scheme that R2-121465 proposes is: base station eNB provides a series of DRX parameter to user equipment (UE).Moving what business because UE can understand it, how its packet arrives distribution, and the information of other cross-layers, so UE chooses most suitable DRX parameter from these a series of DRX parameters, and selected parameter reference is informed to eNB.ENB takes the selection of UE into account, and in conjunction with correlative factor (such as offered load etc.), for UE configures final DRX parameter (UE is selected, or changed by eNB).
In addition, the battery status information of UE also can be provided for eNB, so that eNB determines the parameter configuration of DRX.For example, if UE has sufficient electric weight, eNB can set the DRX parameter be suitable for than high real-time so, and if the electric weight of UE is limited, eNB can be optimized the DRX parameter so, for example sets the DRX parameter that is suitable for hanging down real-time, thereby the saving electric weight, make the stand-by time of UE longer.R2-121465 proposes to use battery charge level, and lg electronics proposes to connect indication with power and reports the battery situation that battery information can not accurately reflect the user.

Fig. 2 shows the schematic diagram of the latency delays under the miscellaneous service scene according to another implementation of the invention.
Embodiment
At first, when base station eNB determines that user equipment (UE) need to carry out DRX, initial discontinuous reception parameters, based at least arbitrary situation as follows, is determined in base station:
The QoS of the data to be transmitted of this subscriber equipment;
The downlink business situation;
System situation, for example load.
Base station eNB is not also known the service conditions of user equipment (UE), and therefore in general, the determined DRX parameter in base station is to arrange according to the qos requirement of the radio bearer of business mapping, for background service and the simultaneous business scenario of live traffic.
Afterwards, the base station discontinuous reception parameters that this is initial sends to user equipment (UE).
User equipment (UE) is known the business that it is moving, when it is moving background service and live traffic at present simultaneously, due to the business scenario of the definite applicable UE of DRX parameter of base station eNB, so user equipment (UE) is directly used this initial discontinuous reception parameters to communicate; When it is only moving background service at present, this DRX parameter may be unmatched with background service, and for example this DRX is applicable to higher real-time, for real-time, can have certain power dissipation during lower background service.So user equipment (UE) sends indication to base station, this indication indicates this user equipment (UE) and only has background service.Aspect specific implementation, this indication can be passed through the MAC signalling.
Base station eNB receives this indication, and DRX parameter definite and this first kind business coupling, then, this DRX parameter is offered to this user equipment (UE).
User equipment (UE), after receiving this DRX parameter, arranges this parameter, completes setting up procedure.
Afterwards, user equipment (UE) communicates based on this DRX parameter.
As shown in Figure 1, in 1st hour (0-1h0m), the user equipment (UE) business of only having powerful connections, so base station eNB is that DRX cycle in the DRX parameter selected of user equipment (UE) is 1024ms, postpones as shown in fig. 1.
Afterwards, in 2nd hour (1h0m-2h0m), except the background service of having moved before, user equipment (UE) has also started a live traffic.These two business can be mapped on identical or different radio bearer (RB).Anyway, the RB that live traffic is mapped to has relatively high expectations to real-time, needs shorter delay.
User equipment (UE) sends indication to base station, this indication indicates this subscriber equipment and has background service and live traffic, and base station eNB receives this indication.
Afterwards, base station eNB is determined the DRX parameter with this background service and live traffic coupling, and this DRX parameter is sent to this user equipment (UE), and user equipment (UE) receives and arrange this DRX parameter.
Afterwards, user equipment (UE) communicates based on this DRX parameter.
As shown in Figure 1, in 2nd hour, user equipment (UE) has background service and live traffic, so base station eNB is that DRX cycle in the DRX parameter selected of user equipment (UE) is 32ms, to guarantee the requirement of live traffic to real-time, postpones as shown in fig. 1.
Afterwards, in 3rd hour (2h0m-3h0m), live traffic finishes, the user equipment (UE) business of only having powerful connections again.
User equipment (UE) sends indication to base station, this indication indicates this subscriber equipment and only has background service, and base station eNB receives this indication.
Afterwards, base station eNB is determined the DRX parameter with this background service coupling, and this DRX parameter is sent to this user equipment (UE), and user equipment (UE) receives and arrange this DRX parameter.
Afterwards, user equipment (UE) communicates based on this DRX parameter.
As shown in Figure 1, in 3rd hour (2h0m-3h0m), user equipment (UE) only has background service, so base station eNB is that DRX cycle in the DRX parameter selected of user equipment (UE) is 1024ms, to guarantee the requirement of live traffic to real-time, postpone as shown in fig. 1.
Afterwards, the 4th hour (3h0m-4h0m) neutralizes in 5th hour (4h0m-4h30m), and user equipment (UE) has started again respectively live traffic, and this live traffic is finished.Base station eNB is that user equipment (UE) is provided with respectively the DRX parameter that DRX cycle is 32ms and 1024ms, postpones as shown in fig. 1.
At above execution mode, base station eNB is identical for the DRX parameter of the business scenario setting of the business of only having powerful connections.One preferred embodiment in, base station eNB can be selected setting for the business scenario of the business of only having powerful connections from least two group DRX parameters, below will describe this kind of execution mode.
With previous execution mode similarly, base station eNB is not also known the service conditions of user equipment (UE), therefore, in general, the determined DRX parameter in base station is for background service and the simultaneous business scenario of live traffic.
Afterwards, the base station discontinuous reception parameters that this is initial sends to user equipment (UE).
When user equipment (UE) is only moving background service 1 at present, this DRX parameter should be unmatched with background service, and for example this DRX is applicable to higher real-time, for real-time, can have certain power dissipation during lower background service 1.So user equipment (UE) sends indication by base station, this indication indicates this subscriber equipment and only has background service.Aspect specific implementation, this indication can be passed through the MAC signalling.
Base station eNB receives this indication, and determines the DRX parameter of mating with this background service from a plurality of DRX parameters.As will be described in more detail, user equipment (UE) can be fed back according to the communication performance of determined this DRX parameter, finally determines final DRX parameter.So, when determining this DRX parameter, base station eNB can be determined in the DRX parameter Candidate Set in being applicable to background service according to the height that is applicable to real-time, for example, in order to guarantee that background service obtains shorter delay, preferentially selects to be applicable to the higher DRX parameter of real-time; Again for example, in order to make subscriber equipment, save power, preferential selection is applicable to the lower DRX parameter of real-time; Perhaps, also can select at random.Then, base station eNB offers this user equipment (UE) by this DRX parameter.
User equipment (UE), after receiving this DRX parameter, arranges this DRX parameter, completes setting up procedure.
Afterwards, user equipment (UE) communicates based on this DRX parameter.
For example, save power in order to make subscriber equipment, in DRX parameter Candidate Set in being applicable to background service, select to be applicable to the lower DRX parameter of real-time, the DRX parameter that base station eNB is preferably the user equipment (UE) setting is parameter 1, and in this parameter, DRX cycle is 1024ms.User equipment (UE) communicates based on this DRX parameter, and as shown in the last short time in 1st hour (0h0m-1h0m) in Fig. 2, maximum delay is 1024ms.
And user equipment (UE) is also observed the communication performance based on this DRX parameter communication.Some preferred embodiment in, user equipment (UE) can detect the data volume of data to be sent in buffer, and/or detects the delay of data to be sent.
Afterwards, based on communication performance, determine whether to need to adjust discontinuous reception parameters.Some preferred embodiment in, user equipment (UE) can judge:
-when this data volume and/or delay are greater than certain threshold value, determine that needing to adjust DRX make it be suitable for higher real-time; Perhaps on the contrary,
-when this data volume and/or delay are less than certain threshold value, determine that needing to adjust DRX make it be suitable for lower real-time.
In the present embodiment, the data volume of the data that background service 1 has more greatly and comparatively frequent, in the situation that the data volume that DRX cycle is 1024ms in can causing buffer too much and data delay longer.So the user equipment (UE) judgement needs to adjust DRX makes it be suitable for higher real-time.
Next, user equipment (UE) sends signaling to base station eNB, and this signaling makes it be suitable for higher real-time for asking to adjust discontinuous reception parameters.This signaling can be an angle from specific implementation, and this signaling can be passed through the MAC signalling.
After base station eNB receives this signaling, can, in conjunction with correlative factor, determine the final discontinuous reception parameters of this user equipment (UE).For example, in the present embodiment, base station eNB can arrange DRX parameter 2 to user equipment (UE), is about to DRX cycle and foreshortens to 640ms from 1024ms.As shown in rear a period of time of 1st hour in Fig. 1.
In 2nd hour (1h0m-2h0m), user equipment (UE) has also started live traffic.Similar with previous execution mode, user equipment (UE) sends indication to base station eNB, indicates it and has background service and live traffic.Therefore, base station eNB is that user equipment (UE) arranges DRX parameter 3, and DRX cycle wherein is 32ms, to guarantee the requirement of live traffic to real-time, postpones as shown in Fig. 2 2nd hour.
In 3rd hour (2h0m-3h0m), user equipment (UE) has stopped live traffic and background service 1, and has started background service 2.
User equipment (UE) sends indication to base station, this indication indicates this subscriber equipment and only has background service, and base station eNB receives this indication.
Afterwards, base station eNB is determined the DRX parameter of mating with this background service.In one embodiment, with 1st hour similarly, in order to make subscriber equipment save power, in the DRX parameter Candidate Set of base station eNB in being applicable to background service, to select to be applicable to the lower DRX parameter of real-time, the DRX parameter that is the user equipment (UE) setting is parameter 1.User equipment (UE) communicates based on this DRX parameter 1.
User equipment (UE) is also determined the communication performance based on this DRX parameter 1 communication, and user equipment (UE) can detect the data volume of data to be sent in buffer, and/or detects the delay of data to be sent.
In the present embodiment, the data volume of the data that background service 2 has is less and not frequent, in the situation that DRX cycle is 1024ms, the data volume in buffer and data delay are all suitable.So user equipment (UE) can not judge needs to adjust the DRX parameter.
In another embodiment, because the final set DRX parameter of user equipment (UE) that base station eNB is the business of only having powerful connections before is parameter 2, base station eNB can be got off this reference record, the DRX parameter 2 arranged for user equipment (UE) in 3rd hour.
User equipment (UE) communicates based on this DRX parameter 2, as shown in the last short time of 3rd hour in Fig. 2.
And user equipment (UE) is also determined the communication performance based on this DRX parameter communication, user equipment (UE) can detect the data volume of data to be sent in buffer, and/or detects the delay of data to be sent.
In the present embodiment, the data volume of the data that background service 2 has is less and not frequent, in the situation that DRX cycle is 640ms, the data volume in buffer is less and data delay is shorter.So, for reasons such as saving power, user equipment (UE) can judge that needing to adjust DRX make it be suitable for lower real-time.
Next, user equipment (UE) sends signaling to base station eNB, and this signaling makes it be suitable for higher real-time for asking to adjust discontinuous reception parameters.From the angle of specific implementation, this signaling can be passed through the MAC signalling.
After base station eNB receives this signaling, can, in conjunction with correlative factor, determine the final discontinuous reception parameters of this user equipment (UE).For example, in the present embodiment, base station eNB can arrange DRX parameter 1 to user equipment (UE), is about to DRX cycle and extends to 1024ms from 640ms.As shown in rear a period of time of 3rd hour in Fig. 2, maximum delay is 1024ms.
Afterwards, in the 4th hour (3h0m-4h0m) and 5th hour (4h0m-4h30m), user equipment (UE) has started again respectively live traffic, and this live traffic is finished.Base station eNB is that user equipment (UE) is provided with respectively the DRX parameter that DRX cycle is 32ms and 1024ms, postpones as shown in Figure 2.
In the above embodiment, by user equipment (UE), come to adjust the DRX parameter according to the communication performance request.In the execution mode of a variation, also can automatically adjust the DRX scheme according to communication performance by base station eNB, for example base station eNB can determine institute's buffer memory user equipment (UE) downlink data data volume or whether excessively or too small postpone, and adjust the DRX parameter according to this performance and make it be applicable to higher or lower real-time.
In one aspect of the method, the actual preference that the mutual battery charge level of user equipment (UE) of the prior art and base station eNB and charged state can not be reacted the user.For example, the user who holds high electric weight user equipment (UE) need to save power as far as possible, because he can't change battery or charging within a period of time; Perhaps, the user who holds low electric weight user equipment (UE) does not need to save power, and needs shorter delay, because he has reserve battery or can charge.In order to address this problem, in embodiments of the present invention, user equipment (UE) receives the power consumption preference of user's input, and this power consumption preference is sent to this base station eNB.This base station eNB can be determined the discontinuous reception parameters of subscriber equipment according to this power consumption preference, and this discontinuous reception parameters is sent to subscriber equipment.For example, the power preference is while saving power, and base station eNB can be determined the longer DRX parameter of use DRX cycle; And when the power preference be while not needing to save power, base station eNB can be determined and uses the shorter DRX parameter of DRX cycle.
Perhaps, the discontinuous reception parameters that user equipment (UE) sends according to base station communicates, and user equipment (UE) is determined corresponding communication performance.User equipment (UE) receives the power consumption preference of user's input, and, according to this power consumption preference and this communication performance, determines whether to need the request base station to adjust discontinuous reception parameters.For example, too high when postponing, and the power preference is while not needing to save power, user equipment (UE) can send the adjustment signaling; And, when the power preference is saving power, user equipment (UE) does not send signaling.
It should be noted that, in the situation that do not conflict, the embodiment in the application and the feature in embodiment be combination in any mutually.
Certainly; the present invention also can have other various embodiments; in the situation that do not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art can make according to the present invention various corresponding changes and distortion, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.For example, several groups of DRX parameters that are applicable to background service can also comprise different ON time and different inertia timer.
One of ordinary skill in the art will appreciate that all or part of step in said method can come the instruction related hardware to complete by program, described program can be stored in computer-readable recording medium, as read-only memory, disk or CD etc.Alternatively, all or part of step of above-described embodiment also can realize with one or more integrated circuits.Correspondingly, each the module/unit in above-described embodiment can adopt the form of hardware to realize, also can adopt the form of software function module to realize.The present invention is not restricted to the combination of the hardware and software of any particular form.
