技术领域 FIELD

[0001] 本发明涉及一种在无线通信系统中自适应调整用户的非连续接收模式的方法和装置,特别是,涉及根据无线信道的状况自适应地设置用户的非连续接收参数,从而进一步提高非连续接收模式的节电效率的方法和装置。 [0001] The present invention relates to a method and apparatus for adaptively adjusting a user in a wireless communication system, the discontinuous reception mode, in particular, it relates to adaptively set the user parameters according to the DRX status of wireless channels, thereby further improving method and apparatus for efficient discontinuous reception power saving mode.

背景技术 Background technique

[0002]第三代合作伙伴项目(3rd Generation Partnership Pro ject,3GPP)作为移动通信领域的重要组织极大地推动了第三代移动通信技术(The Third Generation, 3G)的标准化进展。 [0002] The Third Generation Partnership Project (3rd Generation Partnership Pro ject, 3GPP) as an important organization in the field of mobile communications has greatly promoted the third generation mobile communication technology (The Third Generation, 3G) standardization progress. 3GPP制定了一系列包括宽带码分多址接入(Wide Code Division Multiple Access, WCDMA)、高速下行分组接入(High Speed Downlink Packet Access, HSDPA)、高速上行分组接入(High Speed Uplink Packet Access,HSUPA)等在内的通信系统规范。 3GPP established a series comprising a WCDMA (Wide Code Division Multiple Access, WCDMA), high speed downlink packet access (High Speed ​​Downlink Packet Access, HSDPA), HSUPA (High Speed ​​Uplink Packet Access, communication system specification HSUPA), etc.,. 为了应对宽带接入技术的挑战,并满足日益增长的新型业务的需求,3GPP在2004年底启动了3G 长期演进(LTE =Long Term Evolution)技术的标准化工作,希望进一步提高频谱效率,改善小区边缘用户的性能,降低系统延迟,为高速移动用户提供更高速率的接入服务等。 To meet the challenges of broadband access technology, and to meet the growing demand for new services, 3GPP in late 2004 launched the 3G Long Term Evolution (LTE = Long Term Evolution) standardization of technology and hopes to further improve the spectral efficiency, improve cell-edge user performance, reduce system delay, to provide higher speed access service for the high-speed mobile users, and the like.

[0003] 在上述移动通信系统中,用户和基站之间信息的交互基于双方能量的供给。 [0003] In the mobile communication system, the interaction between the user and the base station information based on both the energy supply. 对于诸如手机、笔记本电脑等绝大多数由电池供电的移动台,其能量储备有限。 For such as mobile phones, notebook computers, the vast majority of battery-powered mobile station, its limited energy reserves. 因此,如何降低能量消耗从而延长用户的待机和服务时间是移动通信系统中需要考虑的关键问题之一。 Therefore, how to reduce energy consumption and thereby extend the service user's standby time is a key issue in mobile communication systems to be considered.

[0004] 为了实现该目的,3GPP的标准中采用了非连续接收(Discontinuous Reception, DRX)模式,通过让用户在与基站约定好的特定时间段内监听信道并接收下行业务,可以减少不必要的监听信道的时间,降低用户的能量消耗。 [0004] In order to achieve this object, in the 3GPP standard uses discontinuous reception (Discontinuous Reception, DRX) mode, so the user by a good agreement with the specific period of time the base station monitoring the channel and receiving downlink traffic, reduce unnecessary monitoring the channel time, and reduce power consumption. 这种DRX模式同样被LTE所采纳。 Such DRX mode is also adopted by LTE. 相比于3GPP之前的标准,虽然在其应用的状态、信道以及触发条件上等略有不同,但用户在DRX 模式下的操作流程是相同的,都可以用几个特定的参数来表征。 Compared to the previous 3GPP standard, although the state of the application, and the channel upper trigger condition is slightly different, but the user operational flow in the DRX mode are the same, it can be used to characterize several specific parameters.

[0005] 图1示出了用户在非连续接收模式下的操作流程。 [0005] FIG. 1 shows a flow of user operation in a discontinuous reception mode. 如图1所示,在DRX模式下,用户UE(移动终端)交替地处于“激活期” (Active Period)和“睡眠期” (Sleep Period)。 As shown, in the DRX mode, the user UE (mobile terminal) alternately in the "active period" (Active Period), and "sleep" (Sleep Period) 1. 在两次连续的激活期的开始时刻,也就是激活期起始点(APSP =Active Period Starting Point)之间的时间间隔被称为一个非连续接收周期(DRX cycle) 0在激活期内,用户开启其接收机(Receiver,Rx)以监听控制信道的信息并接收下行数据;而在睡眠期内,UE不需要监听控制信道,从而达到省电的目的。 At the starting point of two successive active period, i.e. the time between the active period starting point (APSP = Active Period Starting Point) interval is referred to as a discontinuous reception cycle (DRX cycle) 0 in the active period, the user turns its receiver (receiver, Rx) to monitor information on a control channel and receive downlink data; while in the sleep period, the UE does not need to monitor the control channel, so as to save battery power. 在针对LTE进行整体描述的规范中,对用户处于无线资源控制连接(RRC_C0NNECTED)状态下的DRX进行了说明,并给出以下定义: In the specification for the overall description of LTE, DRX of the user is connected to the radio resource control (RRC_C0NNECTED) state has been described, the following definitions are given:

[0006]-开启持续时间(on-duration):用户从DRX的睡眠期醒来后等待接收物理下行控制信道(PDCCH :Physical Downlink Control Channel)的时间,其单位为传输时间间隔(TTI transmission Time Interval,)。 [0006] - opening duration (on-duration): the user waits to receive physical downlink control channel (PDCCH: Physical Downlink Control Channel) from the DRX sleep period to wake up time, the unit of transmission time interval (TTI transmission Time Interval ,). 用户在从DRX睡眠状态醒来时进入该开启持续时间,如果在这段时间内用户成功地对PDCCH进行了解码,用户将保持醒(Awake)的状态,并启动非激活定时器(Inactivity Timer);否则,用户将在DRX配置允许的情况下进入DRX睡眠状态。 Users enter the open when waking up from DRX sleep duration, if the user is successfully decoded the PDCCH during this time, the user will remain awake (Awake) state, and starts the inactivity timer (Inactivity Timer) ; otherwise, the user will enter the DRX sleep state in the case of DRX configuration permits.

[0007]-非激活定时器(inactivity timer):用户从上一次成功解码PDCCH之后等待再次成功解码PDCCH的时间,其单位为TTI。 [0007] - inactivity timer (inactivity timer): the wait time once again successfully decoded the PDCCH after successfully decoding a PDCCH from users on units of TTI. 如果用户成功地对PDCCH进行了解码,用户将保持醒的状态,并且再次启动非激活定时器,直到某个媒体接入控制(MAC=Medium Access Control)头或者控制消息告诉用户重新进入非连续接收状态,并明确地在MAC有效载荷中指示DRX的周期;或者,该用户在非激活定时器结束时按照预先设定的DRX周期自动重新进入非连续接收状态。 If the user is successfully decoded the PDCCH, the user will keep the awake state and starts the inactivity timer again, until a certain Medium Access Control (MAC = Medium Access Control) header or a control message telling the user to re-enter the discontinuous reception state, and explicitly indicated in the MAC payload DRX cycle; or, the user is automatically re-enters DRX according to a predefined state at the end of DRX cycle inactivity timer.

[0008] -DRX周期(DRX Cycle):两个相邻的开启持续时间之间所间隔的时间,这段时间中可能包含处于非激活定时器的时间 [0008] -DRX cycle (DRX Cycle): two adjacent time interval between the opening duration, during which time period may contain an inactive timer

[0009]-激活时间(active time):用户处于醒的状态的时间,包括一个DRX周期内的开启持续时间以及在非激活定时器结束前用户进行连续接收的时间。 [0009] - activation time (active time): the user is awake state time, including within the on-duration and DRX cycle before the end of the inactivity timer in the continuous reception time of the user. 该激活时间的最小值等于开启持续时间,最大值没有限制。 The activation time is equal to the minimum opening duration, the maximum is not limited. 在上述定义的参数中,开启持续时间和非激活定时器是固定的值,由演进的通用地面无线接入网络增强型B节点(Evolved Universal Terrestrial Access Network NodeB,eNB)(基站)通知用户来进行设置,而激活时间则取决于调度策略以及用户对PDCCH的解码成功与否。 In the above-defined parameters, the on-duration and inactivity timer is a fixed value, the evolved universal terrestrial radio access network enhanced Node B (Evolved Universal Terrestrial Access Network NodeB, eNB) (the base station) to notify the user settings, and activation time depends on the scheduling policy and decode PDCCH user success.

[0010] 通过上述非连续接收,用户不需要持续监听信道,而只是间隔性地在某些特定的时刻醒来,从而减少因为不必要地监听信道以及解码不属于自己的数据而造成的能量消耗,延长用户的待机和服务时间。 [0010] By the above-mentioned discontinuous reception, the user need not continuously monitor the channel, but only intermittently in a certain time to wake up, thereby reducing unnecessary energy because monitoring the channel and decoding of data not own consumption caused in longer standby time and service. 但是,非连续接收也在时间上限制了用户对下行数据的接收。 However, the DRX limits the user to receive the downlink data is also time. 例如,在图1中,当用户处于睡眠期的时候,即使用户有可能被调度,eNB也要等到该用户的下一次激活期时才会调度该用户,因此,这些数据被延迟。 For example, in FIG. 1, when the user is in a sleep period, even though the user is likely to be scheduled, the eNB schedules the user will have to wait until the next active period of the first user, therefore, these data are delayed. 也就是说,用户的激活期限制了用户参与调度的时间;另一方面,由于信道条件的变化,用户在有些时刻被调度的可能性比较低,但是由于激活期的设置使得用户在这个时刻醒来,但是并没有数据的传输,由此增大了无谓的能量损耗。 That is, the user activates a time limit of scheduled user participation; on the other hand, due to changes in channel conditions, some time the possibility of the user being scheduled is relatively low, but since the active period of time such that the user woke to, but no data transmission, thereby increasing unnecessary energy loss. 造成这两种结果的主要原因是,在多用户情况下,调度器的调度结果除了和参与调度用户的激活时间有关,还直接受到各个用户无线信道状况的影响,所以, 要实现更加有效的节电效果,就应该自适应地调整用户的DRX参数配置,使其与无线信道状况相配合。 The main cause of these two results is that in a multi-user situations, in addition to scheduling result of the scheduler and the activation time involved in scheduling users, but also on individual users directly affected by the wireless channel conditions, therefore, to achieve a more efficient section electric effect, a user should be adaptively adjusted DRX parameters configuration, it cooperates with wireless channel conditions.

[0011] 图2和3分别示出了在不同用户数的情况下进行非连续接收时对调度结果影响的示意图。 [0011] Figures 2 and 3 show a schematic view of the impact on the scheduling results when discontinuous reception in a case where the number of different users. 这里把无线资源表示为二维无线资源块的集合,横轴代表时间域,以TTI为单位, 纵轴代表频域,以子载波为单位。 Here the radio resource represented as a set of two-dimensional radio resource blocks, the horizontal axis represents the time domain in units of TTI, the vertical axis represents the frequency domain, subcarrier units. 这样,在一个TTI内,一定数目的子载波(比如LTE中通常采用12个连续的子载波)组成的二维区域被称为一个资源块(RB:ReS0Urce Block),对应的一个TTI内资源块的数目用Neb来表示。 Thus, within a TTI, a number of sub-carriers (such as LTE commonly employed contiguous subcarriers 12) consisting of a two-dimensional area is referred to as resource blocks (RB: ReS0Urce Block), the corresponding resource block within a TTI the number represented by Neb. 图2以Nkb = 2为例给出了在不同用户数的情况下进行非连续接收时对调度结果影响的示意图。 Figure 2 Nkb = 2 gives a schematic view of an example non-continuous influence on the result of scheduling received in the case of different numbers of users. eNB (基站)基于这样的无线资源集合进行资源分配,并在相应的资源块上把数据传递给对应的用户。 eNB (base station) based on a set of radio resource allocation of resources, and transfers the data to the user corresponding to the respective resource blocks. 如图2所示,假设当前系统中有四个用户UEl, UE2, UE3, UE4,他们处于非连续接收状态并且具有相同的DRX周期和不同的激活期,在各自定义好的时间段内醒来监听信道并且接收属于自己的数据。 2, assume that the current system has four users UEl, UE2, UE3, UE4, they are in DRX state and have same DRX cycle and active period different, are each defined in the wake period listens to the channel and receives its own data. 每个时刻eNB 都会检测处于激活期的用户,并且在存储器中有指向他们的数据时,为他们分配资源。 Each time a user is detected eNB will be active period, and there are pointing their data, allocate resources to them in a memory. 当用户数从4增大到6的时候,如图3所示,假设用户的DRX参数配置没有改变,可以看到此时用户3(UE3)和用户4(UE4)由于有了用户5和6的竞争,在有的激活期内没有被调度上,要等到下次激活期才会被调度,这样就会使得用户3,4造成了无谓的功率损耗。 When the number of users increases from 4 to 6, when, as shown in FIG. 3, assume that the user does not change the DRX parameters, the user can see the case 3 (the UE3), and the user 4 (UE4) Thanks to the user 5 and 6 competition, not in some activation period is on schedule to wait until the next activation period will be scheduled, so users will make 3,4 caused unnecessary power loss. 从系统角度看,由于多用户分集,每个时刻处于激活期的用户数越多,会有越高的系统吞吐量。 From a system perspective, since the multi-user diversity, at each moment of activation of the more the number of users, the system throughput will be higher.

[0012] 图4示出了系统吞吐量随处于激活期的用户数的改变而变化的趋势示意图。 [0012] FIG. 4 shows a change with a certain number of active users of the system varies tendency FIG. 如图4所示,虽然系统的吞吐量随着参与调度的用户数的增大而增大,但是当用户数达到一定数量以后,系统吞吐量的增长并不明显,用户的耗电量却与处于激活期的时间长度成正比例关系。 4, although the throughput of the system increases as the number of users participating in the scheduling increases, but when the number of users reaches a certain quantity, not significantly increase the system throughput, but with the user's consumption length proportional relationship of the time in the active period. 因此,一味地增大激活用户数并不能明显地改善系统吞吐量,反而会增大用户的耗电量。 Thus, increasing the number of active users blindly and can not significantly improve the system throughput, but will increase the power consumption of the user. 另外,系统的负载是随时间变化的,例如,白天工作时间系统负载比较大,夜间时系统负载比较小,如果采用相同的DRX参数配置,就会使得系统负载大的时候处于激活期的用户数过多,无谓地消耗用户电量。 Further, the load system that change with time, for example, work during the day time the system load is relatively large at night when the system load is relatively small, if the same DRX configuration parameters, so will the number of users in the system load when the active period of excessive, wasteful consumption of electricity users.

[0013] 图5示出了信道变化情况不同的用户在相同的DRX非激活定时器设置下,所处激活期的示意图。 [0013] FIG. 5 shows a schematic diagram of the channel changes in different user in the same DRX inactivity timer is provided, in which the active period. 如图5a所示,当用户的信道变化较慢时,例如用户移动速度比较小时,在开启的某个非激活定时器内,一旦用户在某个时刻不被调度,由于信道相关性的影响,非激活定时器内后面的时间不被调度的可能性也比较大,即Periodl内不被调度的可能性比较大。 5a, the channel variation is slow when a user, for example, the moving speed of the user is relatively small, in a certain open inactivity timer, once the user is not scheduled at a certain time, due to the correlation channel, the possibility of inactive behind the scheduled time of the timer is not relatively large, i.e., the possibility is not scheduled in Periodl relatively large. 如果非激活定时器过长,这个用户就可能在很长的时间内处于激活而没有被调度的状态,也就是无谓地消耗了电量。 If the inactivity timer is too long, the user may be active for a long period of time without being scheduled state, that is needlessly consume power. 相反,如果将非激活定时器设置为比较短的值,则不会发生这种情况,并且由于只要用户被调度,就会重新开启一个非激活定时器,所以用户并不会错过可能被调度的时间。 Conversely, if the inactivity timer is set to a relatively short value, no this happens, and because as long as the user is scheduled, it will re-open a inactivity timer, so users will not miss might be scheduled time. 如图5b所示,当用户的信道变化比较快的时候,例如,用户移动速度比较大时,该用户在某个时刻是否被调度与在此后的时间内被调度的可能性相关性不强。 5b, when the channel changes faster when the user, for example, when the moving speed of the user is relatively large, and whether the user is scheduled to be scheduled within a further time at a time the possibility is not very relevant. 所以,用户的激活时间越长,可能被调度的机会越多。 So, the longer the user's activation time, more opportunities may be scheduled. 这样,如果根据传统的方法,即在不同的信道变化速度的情况下,给用户设置相同的非激活定时器时间长度,会使得信道变化慢的用户无谓地消耗电量,而信道变化快的用户的传输速率受到限制,也即DRX的节能效率没有得到更好的利用。 Thus, if according to the conventional method, i.e., in the case of different rates of channel variation, the user is provided the same inactive length timer, it will make channel changes slowly user wasteful consumption of electricity, and the channel variation speed of the user limited transmission rate, i.e. DRX energy utilization efficiency is not better. 因此需要根据无线信道的状况,自适应的调整DRX参数,从而获得更加有效率的节能效果。 The wireless channel quality is required, DRX parameters adjusted adaptively, so as to obtain more efficient energy saving effect. 即,在极小的吞吐量损失的情况下,节省更多的用户能量。 That is, in the case of a very small throughput loss, the users save more energy.

[0014] 如上所述,用户的非连续接收取决于几个参数的设置:开启持续时间、非激活定时器、DRX周期。 [0014] As described above, depending on the user's DRX setting several parameters: on-duration, inactivity timer, the DRX cycle. 其中开启持续时间和DRX周期在很大程度上决定了用户处于激活期的时间所占的比例,从而也就决定了在某一时刻整个系统中处于激活期的用户数的多少。 In which the on-duration and DRX cycle largely determine the proportion of time a user is active on the share, which also determines the number of how many users are active on at some point throughout the system. 因此,通过调整DRX周期和开启持续时间的关系,可以调整处于激活期的用户数,从而解决系统负载大时的节电问题。 Thus, by adjusting the DRX cycle duration and open relationship, you can adjust the number of users in the active phase, so as to solve problems when large energy-saving system load. 另一方面,非激活定时器的长度决定了用户被调度后连续监听信道的时间,对用户的激活时间也有影响。 On the other hand, the length of the inactivity timer determines the time of continuous monitoring the channel the user is scheduled, the user's activation time is also affected. 因此,根据信道变化快慢调整现有技术中用户的非激活定时器时间长度,可以有效地提高不同信道变化用户混合情况下的节能效率。 Thus, channel variation speed adjustment inactivity timer length according to the prior art, a user can effectively improve the mixing of different user channel variation in a case where the energy efficiency. 在现有的技术中,开启持续时间、DRX周期和非激活定时器通常由用户的业务类型所决定,并且不随着系统负载的多少和信道变化的快慢进行调整。 In the prior art, the opening duration, and period of the DRX inactivity timer is typically determined by the type of user service, and is not adjusted with the channel number and the speed of change of the system load. 然而,从前面的分析可以看出,这样设置DRX 参数的方式,会使得部分用户在不太可能被调度的时刻被激活,无谓地耗费电量,而另一部分用户可能在即便可能被调度的情况下仍然处于睡眠期,降低了系统的吞吐量。 However, the analysis can be seen from the foregoing, this embodiment is provided DRX parameters, so that some users will be less likely to be activated at the scheduled time, needlessly consuming power, while another portion of the user may be possible even in the case where the scheduled still in sleep, reduce the throughput of the system.

[0015] 综上所述,传统DRX参数设置方法的节电效率有待提高。 [0015] In summary, the power saving efficiency of the conventional method of setting the DRX parameters to be improved. 因此需要一种方法来解决传统DRX参数设置方法节电效率不高的问题,使得在保证系统吞吐量要求的情况下,更加有效地节省用户的电量、延长用户待机时间。 Therefore a method is needed to solve the conventional DRX parameter setting method of saving efficiency is not high, so that to ensure that in the case of system throughput requirements, users more effectively save power in longer standby time.

具体实施方式 Detailed ways

[0037] 下面参照附图对本发明的实施例进行详细说明,在描述过程中省略了对于本发明来说是不必要的细节和功能,以防止对本发明的理解造成混淆。 [0037] Referring to the drawings Embodiments of the invention will be described in detail, it is omitted for the present invention in unnecessary detail and functions described process, in order to prevent confusion of the understanding of the present invention.

[0038] 根据本发明,为了保证无线通信系统的吞吐量并节省用户的电能损耗,需要根据无线信道状况来自适应地设置DRX参数,以提高DRX模式的节电效果。 [0038] According to the present invention, in order to ensure the throughput of the wireless communication system user and save power consumption, it is necessary to adapt the DRX parameters provided from a radio channel condition, the effect to improve the power saving DRX mode. 为此,可以根据无线通信系统中无线信道的不同状况采用不同的方式来设置DRX参数。 For this purpose, DRX parameters may be set in different ways depending on radio channel conditions of a wireless communication system. 下面结合附图对此进行描述。 This is described below in conjunction with the accompanying drawings.

[0039] 第一实施方式 [0039] First Embodiment

[0040] 根据前面描述的系统吞吐量与系统负载之间的关系可以看出,随着在某个时刻处于激活期的用户数量的增多,系统吞吐量增大的数量并不明显。 [0040] As can be seen from the relationship between the throughput of the system previously described and the system load, as at some point in the active period of the increased number of users, the number of system throughput increase is not obvious. 这种情况下,如果额外增多处于激活期的用户数量,对系统吞吐量的贡献很小。 In this case, if an additional increase in the number of users in the active period, the contribution to system throughput is very small. 基于此,可以在系统负载比较少时,希望有足够多处于激活期的用户来保证系统的吞吐量,而在处于激活期的用户数量增大到一定程度后,由于用户数量的增加不能明显增大系统的吞吐量,因此希望限制处于激活期的用户数量,有效率地节省用户的电能。 Based on this, the system load is relatively small, in the hope that sufficient activation of the user to ensure the throughput of the system, while the number of active users increases to a certain extent, due to the increased number of users can not be increased significantly system throughput, it is desirable to limit the number of active users, efficient energy saving of the user.

[0041] 为此,可以根据无线通信系统的负载情况来调整用户的开启持续时间和DRX周期之间的比值。 [0041] To this end, the ratio can be adjusted between the opening duration and the DRX cycle of the user according to the load of the radio communication system. 具体地讲,当无线通信系统的负载大时,可以降低开启持续时间和DRX周期之间的比值,而当无线通信系统的负载较小时,可以提高开启持续时间和DRX周期之间的比 In particular, when a large load of the radio communication system, can reduce the ratio between the opening duration and the DRX cycle, when the load of the radio communication systems is small, the ratio between the opening duration and the DRX cycle can be improved

8[0042] 为了在保证系统吞吐量的情况下节省用户的电能消耗,在本发明中定义了参数K。 8 [0042] In order to save power consumption of the user in ensuring the system throughput, the parameters defined in the present invention K. 参数K表示开启持续时间和DRX周期之间的比值,即K相当于描述了一个用户在一个DRX 周期中处于激活期的时间。 The parameter K represents the ratio between the opening duration and the DRX cycle, i.e. K corresponding to a user is described in the active period of time in one DRX cycle. 从系统的角度来看,K间接地描述了某个时刻处于激活期的用户数量,即Ntl ^ NXK,其中N表示系统负载的大小,Ntl表示希望某个时刻处于激活期的用户数量。 From a system perspective, K indirectly describes a number of users in the active period of time, i.e. Ntl ^ NXK, where N represents the size of the system load, expressed Ntl want a time period in the number of active users. 就是说,可以检测无线通信系统的负载变化量,并根据检测的负载变化量,改变用户在非连续接收周期中处于激活期的时间。 That is, a load variation amount of the radio communication system can be detected, and the detected variation amount according to the load, changing the time of the user is active in the DRX cycle. 如果要控制某个时刻处于激活期的用户数量,可以通过调整K的值来实现。 If you want to control the number of users at some point in the active period, can be achieved by adjusting the value of K.

[0043] 图6示出了根据本发明的第一实施例eNB根据系统负载情况自适应调整开启持续时间和DRX周期之间的比值的流程图。 [0043] FIG. 6 shows a first embodiment of the present invention eNB adaptively adjusting the ratio between the duration of the flowchart of the DRX cycle and turned on according to system load. 下面参考图6描述自适应设置DRX参数的第一实施方式。 Described below with reference to FIG adaptive provided DRX parameters 6 first embodiment.

[0044] 在步骤S601,开始时可以初始化系统负载为N1、开启持续时间和DRX周期之间的比值为&。 [0044] In step S601, the system load may be initialized at the beginning of N1, the ratio between the opening time and the duration of the DRX cycle &. 在步骤S602,基站(eNB)检测当前的系统负载N2,并根据当前的系统负载N2实时地统计系统的负载大小,并且计算负载的变化量ΔΝ。 In step S602, the base station (eNB) detects the current system load N2, N2 and loaded with statistical system load in real time based on the current size of the system, and the load change amount calculating ΔΝ. 在此,N1是初始化时系统的负载大小,N2是实时统计的系统负载大小。 Here, N1 is the size of the load when the system is initialized, N2 is a real-time statistical system load size. 此后,在步骤S603,eNB判断ΔΝ的大小是否满足要求, 即是否大于或等于系统所设置的负载门限值thresholdl,例如thresholdl = 20。 Thereafter, at step S603, eNB determines the size ΔΝ meets the requirements, i.e., is greater than or equal to the load threshold thresholdl system provided, e.g. thresholdl = 20. 当ΔΝ 大于或等于系统所设置的负载门限值thresholdl时,eNB认为需要对DRX的参数配置进行调整。 When the system is greater than or equal ΔΝ set load threshold thresholdl, eNB DRX configuration parameters that need to be adjusted. 这种情况下,流程进行到步骤S605,调整K值的大小。 In this case, the flow proceeds to step S605, adjust the size of the K value. 而当在步骤S603判断ΔΝ小于系统所设置的门限值thresholdl时,eNB认为没有必要调整DRX参数。 When determined in step S603, a threshold value less than the system thresholdl ΔΝ provided, eNB is not considered necessary to adjust the DRX parameters. 此时,流程返回到步骤S602,继续统计负载信息。 At this point, the flow returns to step S602, statistics continue to load information.

[0045] 在步骤S605,eNB根据下面的表达式(1)计算当负载变化时要保持系统吞吐量不变所需要的K值大小,即K2。 [0045] In step S605, eNB according to the following expression (1) is calculated to maintain the system throughput constant K value of the size required when the load changes, i.e., K2.

[0046] K2 = min(—~— ,1) ⑴ [0047] 此后,在步骤S606,比较所计算的K2与初始值K1的大小。 [0046] K2 = min (- ~ -, 1) ⑴ [0047] Thereafter, at step S606, the size of the initial value K1 and K2 comparing the calculation. 当满足条件K2彡K1时, 也就是说系统负载变小的时候,流程进行到步骤S607。 When conditional San K2 K1, that is to say when the system load becomes smaller, the flow proceeds to step S607. 在步骤S607,eNB需要在保证系统吞吐量不受损失的前提下节省电量,计算当保持DRX设置时系统吞吐量的大小是否满足系统对吞吐量的最小值Ctl的要求C(K1)彡Q。 In step S607, eNB to save battery power in ensuring the system throughput without loss premise, whether the size of the system is calculated when the system throughput to meet the minimum throughput Ctl DRX setup requirements while maintaining C (K1) San Q. 如果不改变K值仍然可以满足系统吞吐量要求,即C(K1)彡Ctl,流程则进行到步骤S608,保持当前的DRX参数设置,即K = &。 If the K value is not changed still meet certain system requirements, i.e., C (K1) San Ctl, the flow proceeds to step S608, to keep the current DRX parameters, i.e. K = &. 如果在步骤S607判断C(K1) ^ C。 If the determination at step S607 C (K1) ^ C. 不成立,这表明不改变K值的大小会造成系统吞吐量的损失时,流程则进行到步骤S609。 When not established, indicating that does not change the size of the K value will result in the loss of system throughput, the flow proceeds to step S609. 在步骤S609,eNB会根据系统对吞吐量的最小值Ctl所对应的处于激活期的用户数Ntl、当前时刻总的系统负载以及之前所计算出的K2以及当前时刻的系统负载N2,利用下面的表达式(2)计算出保证系统吞吐量的K值大小。 In step S609, eNB based on the number of users of the system in an active Ntl Ctl minimum throughput corresponding to the current system load and the total time and the current time point K2 previously calculated system load N2, using the following expression (2) ensure that the system throughput is calculated K value of the size.

[0048] K = max (―, K2) (2) [0048] K = max (-, K2) (2)

[0049] 当在步骤S606判断不满足条件K2 > K1时,也就是说系统负载变大的时候,流程进行到步骤S610。 [0049] When the determination condition is not satisfied at step S606 K2> K1, that is to say when the system load increases, the flow proceeds to step S610. 在步骤S610,eNB需要保证同时处于激活期的用户数不要太多,以避免不必要的功率损耗,计算当K值取得初始值K1和计算量K2的均值时所对应的系统吞吐量大小, 并且与初始的系统吞吐量进行比较(步骤610),如果这两者的差值小于系统对吞吐量损失的门限值threShold2(如下面的表达式(3)所示),那么停止计算。 In step S610, eNB needs to ensure that the number of users simultaneously active period is not too much, to avoid unnecessary power loss, when the calculated value of K and K1 is calculated to obtain the amount of the initial value of K2 corresponding to the mean throughput of the system size and (step 610), if the difference is less than both of the door system throughput loss threshold2 limit (as in the following expression (3) below), it stops the calculation of the initial system throughput. 也就是说,在步骤S610, 由于系统负载变大,如果保持K值不变,那么系统内同时处于激活期的用户数增大,但是此时系统的多用户分集已经达到饱和,增加额外的激活用户会带来功率消耗却对吞吐量的贡献很小,所以eNB需要调整K值使得激活的用户不要太多。 That is, in step S610, the system load becomes large since, if the K value remains unchanged, the number of users simultaneously active in the system is increased, but this time multiuser diversity system has reached saturation, additional activation users can bring power consumption but then throughput contribution is very small, so the need to adjust the value of K eNB allows the user to activate not too much.

[0050] [0050]

[0051] 此后,在步骤S611设置当前的K值即为所求的K值。 [0051] Thereafter, at step S611 the current value of the set K is the K value are asking. 如果表达式(3)不成立,则表示当前的K值会使得系统的吞吐量损失过大,需要进一步提高K值的大小。 If the expression (3) does not hold, then the current value of K will make the system throughput loss is too large, need to further increase the size of the K value. 这种情况下, 在步骤S612设置K2 = K,并且返回步骤610继续比较,重复这个过程直到找到满足要求的K值为止(步骤612)。 In this case, the step S612 is provided K2 = K, and returns to step 610 to continue the comparison process is repeated until it finds a K value satisfying the requirements (step 612). 最终得到调整后的开启持续时间和DRX周期之间的比值。 The ratio between the opening duration and DRX cycle adjustment after the finally obtained.

[0052] 图7示出多个用户根据上述第一实施方式调整K值大小的示意图。 [0052] FIG. 7 shows a schematic view of a plurality of users to resize the K value according to the first embodiment. 假设初始时 When the initial hypothesis

尺,所有的用户UE1,UE2,UE3,UE4在一个DRX周期内都会醒来一次,并且醒来的时候都4 Foot, all users UE1, UE2, UE3, UE4 in a DRX cycle will wake up again, and woke up all 4

会被调度上;当系统负载变大时,即用户数从4个增长到6个时,调整K值取为i。 It will be scheduled on; when the system load is increased, i.e. the number of users increased from 4 to 6, the adjustment value is set at K i. 与图2和 2 and FIG.

图3所示的传统方法相比,采用根据本发明的第一实施方式后,每个时刻仍然有用户被调度上,系统的吞吐量得到保证,但是对于每一个用户而言,由于处于激活期的时间比例被缩短,因而功率消耗变小,避免了激活但是没有被调度的情况,因而节电效果更好,待机时间更长。 Compared to the conventional method illustrated in FIG. 3, a first embodiment of the use according to the present invention, each time the user is still scheduled, the system throughput is assured, but for each user, since the active period is proportion of the time is shortened, and thus the power consumption is small, but avoids the situation where the activation is not scheduled, and therefore better energy-saving effect, longer standby time.

[0053] 上面描述了根据系统的负载情况调整开启持续时间和DRX周期之间的比值的方法。 [0053] The above described method of the ratio between the duration and the DRX cycle adjustment open according to the system load. 具体而言,当系统负载较大时,可以通过降低开启持续时间和DRX周期之间的比值,使得在保证无线通信系统的吞吐量的同时,节省用户的能耗;而当系统负载较小时,可以通过提高降低开启持续时间和DRX周期之间的比值,从而在保证无线通信系统的吞吐量的同时,节省用户的能耗。 Specifically, when the system load is large, it can be opened and the ratio between the duration of the DRX cycle by reducing the guaranteed throughput in such radio communication system while saving energy user; and when the system load is small, you can open the ratio between the duration and decreased by increasing the DRX cycle, thus ensuring a certain radio communication system while saving energy user. 为此,可以根据上面描述的计算过程,也可以采用一种遍历的方法, 计算不同的系统负载与不同的信道情况下的K值,获得不同系统负载量与开启持续时间和DRX周期比值之间对应关系的一个映射表(如下面的表1所示),并且保存在基站。 To this end, according to the calculation procedure described above, a method may be employed between the traverse, the value of K calculated in different systems with different channel load, the load on the system and obtain different opening duration and the DRX cycle ratio a correspondence relationship mapping table (as shown in table 1 below), and stored in the base station.

[0054] 表1 [0054] TABLE 1

[0055] [0055]

[0056] 在表1中,Un表示不同的系统负载,Em表示不同的信道情况,Knm表示针对不同的系统负载和信道情况所得到的开启持续时间和DRX周期之间的比值,其中m和η分别是整数。 [0056] In Table 1, Un represents the system load, Em represents a different channel conditions, Knm represents the ratio between the duration of the opening for the system load and channel conditions is obtained and the DRX cycle, wherein m and η They are integers.

[0057] 在实际的通信过程中,当需要开启持续时间和DRX周期之间的比值时,只需要根 [0057] In the actual communication, when the ratio between the duration and the DRX cycle needs to open, only the root

10据当前的系统负载量,通过查找映射表的方式即可获得相应比值。 10, according to the current system load, the ratio can be obtained by looking up the mapping table corresponding manner.

[0058] 为了计算上面表1中所述的开启持续时间和DRX周期之间的比值Knm,可以使基站端预先对可能发生的信道情况进行估计,并且在不同的信道情况下、不同系统负载量时,遍历计算适合的开启持续时间和DRX周期之间的所有比值。 [0058] To calculate the above table the ratio between the opening duration in a claim and the DRX cycle Knm, can make the base station end of the pre-channel may occur are estimated, and in different channel conditions, different loading systems when, through all the ratio between the duration of the DRX cycle and calculates the appropriate opening.

[0059] 需要指出的是,通过遍历计算的方法得到上述映射表与前面给出的自适应调整的方法可以独立存在。 [0059] It should be noted that the calculation method is obtained by traversing the adaptive adjustment of the mapping table given above and can exist independently. 就是说,在实际的通信过程中,可以根据当前的系统负载量实时地计算对应的开启持续时间和DRX周期之间的比值,并且通知给用户。 That is, in the actual communication, the ratio between the corresponding opening duration and the DRX cycle may be calculated in real time based on the current loading of the system, and notifies the user.

[0060] 第二实施方式 [0060] Second Embodiment

[0061] 上面描述了根据系统负载情况自适应调整开启持续时间和DRX周期之间的比值的第一实施方式。 [0061] The above described adaptive adjustment system according to the load ratio between the opening time and the duration of the DRX cycle of the first embodiment. 下面描述利用系统的负载信息和信道变化快慢信息自适应地调整DRX参数的第二实施方式。 Change speed information described below to adaptively adjust the DRX parameters in the second embodiment utilizes the channel information and the load system.

[0062] 根据本发明的第二实施方式可以根据无线通信系统的信道变化的快慢程度来调整非连续接收时间长度。 [0062] discontinuous reception may be adjusted according to the length of time a second embodiment of the present invention according to how fast the channel changes in the wireless communication system. 具体地讲,对信道变化快的用户,增大用户的非连续接收时间长度,对信道变化慢的用户,减小用户的非连续接收时间长度。 In particular, for fast channel variations user, increases the length of time of discontinuous reception user, the channel changes slowly user, reducing the length of the discontinuous reception time of the user.

[0063] 图8示出了本发明的第二实施例eNB根据用户信道变化的快慢程度自适应调整非激活定时器时间长度的流程图。 [0063] FIG. 8 shows a second embodiment of the present invention eNB flowchart of the inactivity timer time length according to the degree of channel variation speed of the user channel adaptive adjustment. 下面参考图8描述自适应设置DRX参数的第二实施方式。 Described below with reference to FIG adaptive provided DRX parameters to the second embodiment 8.

[0064] 根据本发明的第二实施方式,eNB根据用户的移动速度来判断信道变化的快慢程度。 [0064] According to a second embodiment of the present invention, eNB according to the moving speed of the user to determine how fast the channel changes. 用Ti表示非激活定时器时间长度,Ti_slow, Ti_fast和Ti_original分别为慢变信道用户、快变信道用户和初始的非激活定时器时间长度。 Ti represents the length by the time the inactivity timer, Ti_slow, Ti_fast Ti_original are slowly varying and the channel user, and the user fast varying channel length of the initial inactive timer. 如图8所示,开始时,慢变信道用户和快变信道用户的非激活定时器时间长度是相同的,等于初始非激活定时器时间长度。 8, at the start of the slow varying channel user inactivity timer duration and fast varying channel users is the same, equal to the initial length of the inactivity timer. 在步骤S801,eNB通过测量用户的移动速度,可以估测用户的信道变化快慢,移动速度高的用户信道变化快,相反移动速度低的用户信道变化慢,根据系统设置的门限值S1,当用户的移动速度低于这个门限值的时候,eNB判断他为慢变信道用户。 In step S801, eNB by measuring the moving speed of users, can be estimated user channel variation speed, high moving speed of the user channel changes quickly, the opposite lower the moving speed of the user channel changes slowly, according to the threshold value S1 set by the system, when moving speed of the user is lower than the threshold time, eNB determines his user channel is slowly varying. 这种情况下,需要对其非激活定时器时间长度进行调整,例如,将Ti_slow设置为原来的1/2 (步骤802)。 In this case, it is necessary to adjust its length inactivity timer, e.g., a factor of 2 Ti_slow set (step 802). 接着,在步骤S803,eNB计算调整后用户功率节省百分比ΔΡ/仏,其中ΔΡ是平均功率消耗的减少量,Ptl是初始的功率消耗值,并比较功率节省百分比ΔΡ/&与系统门限值threShold3的大小。 Next, after step S803, eNB calculates power saving user to adjust the percentage ΔΡ / Fo, where Ap is the average amount of power consumption reduction, Ptl is the initial value of power consumption, and to compare the percentage of power saving ΔΡ / & threShold3 system threshold the size of. 如果在步骤S803的比较结构表明ΔΡ/Ρ。 If you indicate ΔΡ / Ρ. In step S803 of comparing the structure 大于门限值threShold3,说明用户的节电效率已经达到系统的要求,所以可以停止对慢变信道用户的非激活定时器时间长度Ti_slow 的调整,并且流程进行到步骤804。 Threshold3 greater than the threshold, the user's energy-saving efficiency has been described meet the requirements of the system, it can be adjusted to stop the slow varying channel length of user inactivity timer Ti_slow, and the flow proceeds to step 804. 如果在步骤S803的比较结构表明ΔΡ/Ρ。 If you indicate ΔΡ / Ρ. In step S803 of comparing the structure 不大于门限值threshold3,则说明用户的节电效率仍然需要提高。 Is not greater than the threshold threshold3, then the user still needs to improve the efficiency of energy-saving. 这种情况下,流程返回到步骤802,继续对Ti_slow进行调整,直到节电效率满足系统要求为止。 In this case, the flow returns to step 802 to continue to Ti_slow adjusted until the energy-saving efficiency up to meet the system requirements.

[0065] 在步骤804中,eNB根据系统设置的门限值S2查找快变信道用户。 [0065] In step 804, eNB lookup value S2 fast varying channels according to user setting door system. 当用户的移动速度高于门限值S2的时候,eNB判断其为快变信道用户。 When the moving speed of the user is higher than the threshold value S2, eNB determines that the user is fast varying channel. 在步骤S805,eNB需要对快变信道用户的非激活定时器时间长度进行调整。 In step S805, eNB needs to inactivity timer the length of time the fast varying channel user may be adjusted. 例如,将Ti_fast自加一个TTI长度。 For example, the self-imposed Ti_fast a TTI length. 然后,在步骤S806,eNB计算非激活定时器时间长度调整后系统吞吐量提高的百分比AR/R。 Then, after step S806, eNB calculates the length of time to adjust the inactivity timer to improve system throughput percentage AR / R. ,其中AR 是系统吞吐量的增加量,Rtl是初始时系统的吞吐量,并比较系统吞吐量提高百分比AR7X1 和系统门限值thresholcM的大小。 Wherein AR is the amount of increase system throughput, the throughput is initially Rtl system and compare the percentage of size increase system throughput and system AR7X1 thresholcM the threshold. 如果AR/R。 If AR / R. 大于门限值thresholcM,说明系统吞吐量的损失已经在系统要求范围之内,可以停止Ti_fast的调整。 Greater than the threshold thresholcM, loss of system throughput has been described within the scope of the system requirements, may be stopped to adjust Ti_fast. 这种情况下,在步骤S807,得到调整后的Ti_sl0W,Tu_fast。 In this case, in step S807, the obtained Ti_sl0W adjusted, Tu_fast. 如果AR/R。 If AR / R. 不大于门限值thresholcM,则说明系统吞吐量 Is not greater than the threshold thresholcM, then the system throughput

11损失仍然不能为系统所接收。 11 loss is still not received by the system. 这种情况下,流程返回到步骤805,进一步调整Ti_fast使得吞吐量损失减少,直到满足要求为止。 In this case, the flow returns to step 805, so that the throughput loss is further reduced Ti_fast adjusted, until requirements are met.

[0066] 在图8所示的步骤中,eNB通过测量用户的移动速度获得信道变化快慢的信息,如图中虚线所示部分。 [0066] In the step shown in FIG. 8, the eNB speed obtained channel information by measuring a change in the user's moving speed, the broken line portions shown in FIG. 应该指出,本发明不限于此,也可以通过其他的方法获得这个信息。 It should be noted that the invention is not limited thereto, this information can also be obtained by another method. 例如,eNB可以通过统计用户反馈的下行信道CQI信息的变化来判断下行信道变化快慢。 For example, a change of downlink channel information CQI feedback eNB may be determined by counting the downlink user channel variation speed. 这时,虚线内的部分可以直接用CQI信息变化快慢程度来取代用户的速度信息。 At this time, part of the broken line may be used directly in the rapidity of the CQI information changing speed information instead of the user.

[0067] 图9示出了当多用户的信道变化不同时,根据本发明第二实施方式进行非激活定时器的设置的示意图。 [0067] FIG. 9 shows a schematic view of a multi-user channel variation is not the same, the inactivity timer is set according to a second embodiment of the present invention when the embodiment. 假设初始时所有用户的非激活定时器时间长度都为4,使用本发明的自适应调整方法以后,慢变信道的用户非激活定时器时间长度调整为2,快变信道的用户非激活定时器时间长度调整为6。 Suppose all users initially inactive time length of the timer 4, after using the adaptive adjustment method of the present invention, slowly varying channels the user inactivity timer the length of time is adjusted to 2, the user fast varying channel inactivity timer 6 is adjusted to the length of time. 这样对系统吞吐量贡献较大的快变信道的用户有更多的机会被调度,而慢变信道用户则不会浪费功率来等待调度。 User contributions such large fast varying channel throughput of the system have more opportunities to be scheduled, and the slowly varying channel users will not be wasting power waiting to be scheduled. 从整体系统角度看,用户的平均功率损耗可以被节省。 From the perspective of the overall system, the user's average power consumption can be saved.

[0068] 上面描述了根据信道变化的快慢,调整非连续接收时间长度的方法。 [0068] The method described above according to a channel variation speed, adjustment of the length of time of discontinuous reception. 具体而言,对信道变化较快的用户,可以增大用户的非连续接收时间长度,使得在保证无线通信系统的吞吐量的同时,节省用户的能耗;而对信道变化较慢的用户,可以通过减小用户的非连续接收时间长度,从而在保证无线通信系统的吞吐量的同时,节省用户的能耗。 Specifically, user channel changes rapidly, it is possible to increase the length of the discontinuous reception time of the user, so that to ensure a certain radio communication system while saving energy user; the user channel changes slowly, by simultaneously reducing the length of the discontinuous reception time of the user, thus ensuring throughput of the wireless communication system, the user to save energy. 为此,可以根据上面描述的计算过程,也可以采用一种遍历的方法,计算不同的信道变化速度与不同的信道情况下用户的非激活定时器时间长度,获得信道变化的快慢程度与用户的非激活定时器时间长度之间对应关系的映射表(如下面的表2所示),并保存在基站。 To this end, according to the calculation procedure described above, it may be employed a method of traversing, calculate the length of the inactivity timer time user with a different channel conditions different speed channel variation, to obtain the channel variation speed of the extent of the user's mapping the correspondence relation table (see table 2 below) between the time length of the inactivity timer, and stored in the base station.
