本发明实施例涉及通信领域，并且更具体地，涉及非连续接收(DRX，Discontinuous Reception)的方法及装置。Embodiments of the present invention relate to the communication field, and more specifically, to a method and device for Discontinuous Reception (DRX, Discontinuous Reception).
背景技术Background technique
移动互联网的业务环境已经颠覆了传统电路域业务的话务模型，典型的移动互联网的业务模式如智能机(Smartphone)下的QQ、应用存储(AppStore)、黑莓(BlackBerry)、推特(Twitter)等应用。为了同步业务以及保持心跳，网络中每隔很短时间(几十秒、几分钟)就要传输数据以便相应地触发寻呼和连接建立等流程，从而导致网络的负荷急剧升高。The business environment of the mobile Internet has subverted the traffic model of traditional circuit domain services. Typical mobile Internet business models include QQ, AppStore, BlackBerry, and Twitter on smartphones. and other applications. In order to synchronize services and keep the heartbeat, data must be transmitted in the network at short intervals (tens of seconds, minutes) to trigger paging and connection establishment processes accordingly, resulting in a sharp increase in network load.
为了减少业务模式变化中状态转换的开销，长期演进(LTE，Long TermEvolution)中引入了一个中间状态，即连接态非连续接收(Active DiscontinuousReception，Active DRX)机制。连接态DRX机制允许用户设备(UE，UserEquipment)在保持无线资源控制(Radio Resource Control，RRC)连接的状态下周期性地在睡眠状态和激活状态之间转换。In order to reduce the overhead of state transitions during service mode changes, an intermediate state is introduced into Long Term Evolution (LTE, Long Term Evolution), namely the active discontinuous reception (Active Discontinuous Reception, Active DRX) mechanism in the connected state. The connected state DRX mechanism allows the user equipment (UE, UserEquipment) to periodically switch between the sleep state and the active state while maintaining a radio resource control (Radio Resource Control, RRC) connection state.
连接态DRX机制将UE的连接态分为激活状态阶段和睡眠状态阶段。当UE处于激活状态阶段时，UE的接收天线开启，以便UE接收下行数据包，此时UE的耗电较高；当UE处于睡眠状态阶段，UE的接收天线关闭，UE不能接收下行数据包，此时UE处于省电模式，但RRC连接的上下文依然保持。The connected state DRX mechanism divides the connected state of the UE into an active state stage and a sleep state stage. When the UE is in the active state, the receiving antenna of the UE is turned on so that the UE can receive downlink data packets. At this time, the power consumption of the UE is high; when the UE is in the sleep state, the receiving antenna of the UE is turned off, and the UE cannot receive downlink data packets. At this time, the UE is in the power saving mode, but the context of the RRC connection is still maintained.
现有的连接态DRX机制对UE进入睡眠状态阶段前的一些小的空闲时间，例如UE发送调度请求(schedule request，SR)消息之后等待演进型基站(eNB或e-NodeB，evolutional Node B)调度的过程中以及在混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)消息重传的等待时间内没有其他的数据包发送的情况下，UE仍然需要保持在激活状态阶段，从而需要不断地检测物理下行控制信道(physical downlink control channel，PDCCH)，导致UE更加耗电。另外，连接态DRX周期的变化是通过改变RRC信令的配置来实现，因此通过改变连接态DRX周期来调整连接态DRX机制耗时长、延迟大且不灵活。并且，在需要临时变更DRX参数或者在UE没有配置DRX参数的情况下，eNB无法指示UE快速进入睡眠状态。The existing connected state DRX mechanism is for some small idle time before the UE enters the sleep state stage, for example, after the UE sends a scheduling request (schedule request, SR) message and waits for the scheduling of the evolved base station (eNB or e-NodeB, evolutional Node B) In the process of retransmission and when there is no other data packet sent during the waiting time of Hybrid Automatic Repeat Request (HARQ) message retransmission, the UE still needs to remain in the active state stage, so it needs to constantly detect the physical The downlink control channel (physical downlink control channel, PDCCH) causes the UE to consume more power. In addition, the change of the DRX cycle in the connected state is realized by changing the configuration of RRC signaling, so adjusting the DRX mechanism in the connected state by changing the DRX cycle in the connected state takes a long time, has a large delay and is inflexible. Moreover, when the DRX parameters need to be changed temporarily or the UE is not configured with the DRX parameters, the eNB cannot instruct the UE to quickly enter the sleep state.

具体实施方式Detailed ways
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
本发明实施例的技术方案，UE也可称之为移动终端(Mobile Terminal)、移动用户设备等，可以经无线接入网(例如，RAN，Radio Access Network)与一个或多个核心网进行通信，用户设备可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。In the technical solution of the embodiment of the present invention, the UE can also be referred to as a mobile terminal (Mobile Terminal), mobile user equipment, etc., and can communicate with one or more core networks via a radio access network (for example, RAN, Radio Access Network) , the user equipment may be a mobile terminal, such as a mobile phone (or called a "cellular" phone) and a computer with a mobile terminal, such as a portable, pocket, hand-held, computer built-in or vehicle-mounted mobile device, which communicate with The radio access network exchanges language and/or data.
从UE方面来说，省电是无止境的，尤其是随着即时通信业务的普及，UE的省电变得更加重要。即便在现有的连接态DRX机制中，仍然存在进一步优化的可能性，例如UE在发送SR消息之后，需要等待eNB的调度信息，在这个过程中，仍然有可能存在空闲时间，但是该空闲时间又不够执行一次原有的连接态DRX机制。这种情况下，可以引入新的方法，让UE更加节电。From the aspect of UE, the power saving is endless, especially with the popularization of instant messaging services, the power saving of UE becomes more important. Even in the existing connected state DRX mechanism, there is still the possibility of further optimization. For example, after the UE sends the SR message, it needs to wait for the scheduling information of the eNB. During this process, there may still be idle time, but the idle time It is not enough to execute the original connected state DRX mechanism once. In this case, a new method can be introduced to allow the UE to save more power.
参见图1描述基站侧根据本发明实施例的DRX的方法。如图1所示。Referring to FIG. 1 , the DRX method at the base station side according to the embodiment of the present invention is described. As shown in Figure 1.
11，eNB确定在一个时间段内是否调度UE。11. The eNB determines whether to schedule the UE within a period of time.
12，如果确定在该一个时间段内不调度UE，eNB向该UE发送附加DRX命令，该附加DRX命令用于指示该UE在该一个时间段内执行DRX以处于睡眠状态。12. If it is determined that the UE is not scheduled within the time period, the eNB sends an additional DRX command to the UE, where the additional DRX command is used to instruct the UE to perform DRX within the time period to stay in a sleep state.
在eNB向UE发出附加DRX命令之后，参照图2所示，UE侧根据本发明实施例的DRX的方法包括以下步骤：After the eNB sends an additional DRX command to the UE, as shown in Figure 2, the DRX method on the UE side according to the embodiment of the present invention includes the following steps:
21，UE接收基站发送的附加DRX命令；21. The UE receives the additional DRX command sent by the base station;
22，UE根据附加DRX命令的指示，在一个时间段内执行DRX以处于睡眠状态。22. The UE executes DRX within a period of time according to the indication of the additional DRX command to stay in the sleep state.
本发明实施例的DRX的方法能够使得UE在不被基站调度的空闲时间内更快速进入睡眠状态的问题，使得在不改变UE的现有DRX配置的前提下，在UE没有数据包发送或接收的小段空闲时间内通过附加DRX命令的触发执行新的睡眠模式，从而UE更加节电。The DRX method of the embodiment of the present invention can enable the UE to enter the sleep state more quickly during the idle time that is not scheduled by the base station, so that the UE does not send or receive data packets without changing the existing DRX configuration of the UE A new sleep mode is executed by triggering an additional DRX command in a small idle period, so that the UE can save more power.
由上述可知，连接态DRX周期包括激活状态阶段和睡眠状态阶段，其中在激活状态阶段，UE监听物理下行控制信道，以便获取eNB发送的调度信息；而在睡眠状态阶段，UE不监听物理下行控制信道，而处于睡眠模式中。因此，一个时间段短于连接态DRX周期的激活状态阶段。It can be known from the above that the connected state DRX cycle includes an active state stage and a sleep state stage. In the active state stage, the UE monitors the physical downlink control channel in order to obtain the scheduling information sent by the eNB; while in the sleep state stage, the UE does not monitor the physical downlink control channel. channel while in sleep mode. Therefore, a time period is shorter than the active state phase of the connected state DRX cycle.
具体而言，附加DRX命令包括用于指示DRX的执行时长的信息。因此，无论网络中是否配置了连接态DRX机制的DRX参数，只要UE接收到eNB发送上述附加DRX命令，将根据上述用于指示DRX的执行时长的信息在所指示的时间段内执行睡眠模式。Specifically, the additional DRX command includes information for indicating the execution duration of DRX. Therefore, regardless of whether the DRX parameters of the connected state DRX mechanism are configured in the network, as long as the UE receives the above-mentioned additional DRX command sent by the eNB, it will execute the sleep mode within the indicated time period according to the above-mentioned information indicating the execution duration of DRX.
进一步地，对于配置了连接态DRX机制的DRX参数的情况，除了启动单次优化的DRX之外，还可以启动多次优化的DRX。这样，附加DRX命令可以包括用于指示UE在一个时间段内执行DRX的次数的信息以及用于指示每次DRX的执行时长的信息。DRX的执行时长不大于该时间段，即UE在该时间段中执行一次或多次短DRX睡眠。每当执行一次短DRX，UE进入一次睡眠状态，从而节省功耗。Further, for the case where the DRX parameters of the connected state DRX mechanism are configured, in addition to starting a single optimized DRX, multiple times of optimized DRX may also be started. In this way, the additional DRX command may include information for indicating the number of times the UE performs DRX within a period of time and information for indicating the duration of each DRX execution. The execution duration of DRX is not longer than this time period, that is, the UE performs one or more short DRX sleeps during this time period. Whenever a short DRX is performed, the UE enters a sleep state to save power consumption.
此外，用于指示每次DRX的时长的信息可以包括用于指示UE采用长的或短的优化的DRX周期的信息以及该长的或短的优化的DRX周期的时长的信息，其中，该长的或短的优化的DRX周期短于连接态DRX周期的激活状态阶段。每次DRX的时长是可选的，本实施例给出长的优化的DRX周期和短的优化的DRX周期两种选择，每种选择都是对现有DRX睡眠机制的一种优化。基站可基于实际应用场景为UE选择合适的优化的DRX周期，使得UE在基站不向UE调度数据的时间段内进入睡眠。In addition, the information indicating the duration of each DRX may include information indicating that the UE adopts a long or short optimized DRX cycle and information about the duration of the long or short optimized DRX cycle, where the long The optimized DRX cycle is shorter than the active state phase of the connected state DRX cycle. The duration of each DRX is optional. This embodiment provides two options: a long optimized DRX cycle and a short optimized DRX cycle, and each option is an optimization of the existing DRX sleep mechanism. The base station may select an appropriate optimized DRX cycle for the UE based on an actual application scenario, so that the UE enters sleep during a time period when the base station does not schedule data to the UE.
这样，UE可以根据附加DRX命令执行单次或多次优化的DRX。In this way, the UE can perform optimized DRX once or multiple times according to the additional DRX command.
下面结合图3详细描述UE与eNB进行优化的DRX的具体过程。The specific process of optimizing the DRX performed by the UE and the eNB is described in detail below with reference to FIG. 3 .
如图3所示，当UE已经进入连接模式，并且已经与eNB进行正常通信的过程中，若eNB确定一小段时间内不会调度该UE，则触发UE启动DRX。此时，eNB向UE发送附加DRX命令，指示UE执行DRX。由于该附加DRX命令可以通过修改媒体接入控制(Media Access Control，MAC)层的附加DRX命令得到，而无需修改通过RRC信令下发的DRX参数。一般而言，DRX参数包括：持续时间定时器(onDurationTimer)、DRX非激活定时器(drx-InactivityTimer)、DRX重传定时器(drx-RetransmissionTimer)、长DRX周期偏移(longDRX-CycleStartOffset)、短DRX周期(shortDRX-Cycle)和DRX短周期定时器(drxShortCycleTimer)等。As shown in FIG. 3 , when the UE has entered the connected mode and is in normal communication with the eNB, if the eNB determines that the UE will not be scheduled within a short period of time, the UE is triggered to start DRX. At this time, the eNB sends an additional DRX command to the UE, instructing the UE to perform DRX. Since the additional DRX command can be obtained by modifying the additional DRX command of the Media Access Control (MAC) layer, there is no need to modify the DRX parameters delivered through the RRC signaling. Generally speaking, DRX parameters include: duration timer (onDurationTimer), DRX inactivity timer (drx-InactivityTimer), DRX retransmission timer (drx-RetransmissionTimer), long DRX cycle offset (longDRX-CycleStartOffset), short DRX cycle (shortDRX-Cycle) and DRX short cycle timer (drxShortCycleTimer), etc.
具体而言，如果UE此时已经配置DRX参数或启动了连接态DRX机制，但是eNB确定这一小段空闲时间与已经配置的DRX参数或启动的连接态DRX机制不匹配，例如连接态DRX周期被配置为20个子帧，但是eNB确定这一小段空闲时间只有2个子帧，不够执行一次完整的连接态DRX周期，eNB就通过触发单次或多次DRX来让UE按照附加DRX命令进行睡眠，即让UE只睡眠2个子帧，这样使得UE充分节电。在单次或多次优化的DRX结束之后，UE和eNB都需要恢复原有的连接态DRX机制。例如，原来配置了DRX参数但是没有启动连接态DRX机制的UE将仍然不启动连接态DRX机制，或者原来配置了DRX参数并启动了连接态DRX机制的UE仍然延续原有的连接态DRX机制，即按照原有的DRX参数执行连接态DRX机制。Specifically, if the UE has configured DRX parameters or activated the connected state DRX mechanism at this time, but the eNB determines that this short period of idle time does not match the configured DRX parameters or the activated connected state DRX mechanism, for example, the connected state DRX cycle is disabled The configuration is 20 subframes, but the eNB determines that this short period of idle time is only 2 subframes, which is not enough to perform a complete connected state DRX cycle. The eNB triggers single or multiple DRX to let the UE sleep according to the additional DRX command, that is Let the UE only sleep for 2 subframes, so that the UE can fully save power. After the single or multiple optimized DRX ends, both the UE and the eNB need to restore the original connected state DRX mechanism. For example, UEs that have configured DRX parameters but have not activated the DRX mechanism in the connected state will still not activate the DRX mechanism in the connected state, or UEs that have configured DRX parameters and activated the DRX mechanism in the connected state will still continue the original DRX mechanism in the connected state. That is, the connected state DRX mechanism is executed according to the original DRX parameters.
可以理解，如果UE没有配置DRX参数，也没有启动连接态DRX机制，则eNB就更容易通过触发单次DRX来使得UE执行指定的睡眠时间。但是，如果UE配置了DRX参数，则可执行多次DRX，可利用持续时间定时器等定时器，在合适的时刻开始进入睡眠。It can be understood that if the UE does not configure DRX parameters and does not start the connected state DRX mechanism, it is easier for the eNB to make the UE perform a specified sleep time by triggering a single DRX. However, if the UE is configured with DRX parameters, it can perform DRX multiple times, and it can use a timer such as a duration timer to start going to sleep at an appropriate moment.
下面结合图4和图5的具体实施例描述如何配置附加DRX命令来启动单次或多次DRX。附加DRX命令不同于连接态DRX命令。How to configure an additional DRX command to start single or multiple DRXs is described below with reference to the specific embodiments in FIG. 4 and FIG. 5 . Additional DRX commands are different from connected state DRX commands.
例如，eNB向UE发送的附加DRX命令具有2个字节(Byte)，其中第1个字节使用连接态DRX命令的预留信息位中的1个比特(bit)，例如利用图4至图7所示的第2比特位，来指示eNB向UE发送的DRX命令是附加DRX命令还是连接态DRX命令。一般而言，连接态DRX命令只有1个字节，其中前2个比特作为预留信息位，第3个比特作为扩展信息位，后5个比特作为区域设置标识符(Localization Identity，LCID)。For example, the additional DRX command sent by the eNB to the UE has 2 bytes (Byte), wherein the first byte uses 1 bit (bit) in the reserved information bits of the connected state DRX command, for example, using Figure 4 to Figure 7 to indicate whether the DRX command sent by the eNB to the UE is an additional DRX command or a connected state DRX command. Generally speaking, the connected state DRX command has only 1 byte, of which the first 2 bits are used as reserved information bits, the third bit is used as extended information bits, and the last 5 bits are used as localization identity (LCID).
此外，附加DRX命令的第2个字节中包含DRX的执行时长、或者DRX的执行次数与每次DRX的执行时长、或者长的或短的优化的DRX周期的信息以及与长的或短的优化的DRX周期对应的DRX附加周期的时长等信息，具体可以有以下几种方式。需要说明的是，在下面所述的方式中，比特的位置排列可以发生变化，且都在本发明实施例的保护范围：In addition, the second byte of the additional DRX command contains the execution duration of DRX, or the execution times of DRX and the execution duration of each DRX, or the long or short optimized DRX cycle information and the long or short For information such as the duration of the DRX additional cycle corresponding to the optimized DRX cycle, there may be the following specific methods. It should be noted that, in the manner described below, the arrangement of bits can be changed, and all of them are within the scope of protection of the embodiments of the present invention:
第一种方式，所有8个比特用于指示DRX的执行时长，以子帧为单位，例如00000001指示睡眠1子帧，00000011指示睡眠3子帧，等等。如图4所示。In the first way, all 8 bits are used to indicate the execution duration of DRX in units of subframes, for example, 00000001 indicates sleep 1 subframe, 00000011 indicates sleep 3 subframe, and so on. As shown in Figure 4.
第二种方式，前3个比特用于指示DRX执行的次数，例如000用于表示单次DRX，001用于表示2次DRX，.......依次类推，直到111用于表示8次DRX。第4-8个比特用于指示具体的DRX的执行时长，以子帧为单位。如图5所示。In the second way, the first 3 bits are used to indicate the number of DRX executions, for example, 000 is used to indicate a single DRX, 001 is used to indicate 2 DRXs, ...... and so on, until 111 is used to indicate 8 times DRX. The 4th to 8th bits are used to indicate the specific execution duration of DRX, and the unit is subframe. As shown in Figure 5.
第三种方式，前3个比特用于指示DRX执行的次数，例如000用于表示单次DRX，001用于表示2次DRX，.......依次类推，直到111用于表示8次DRX。第4个比特用于指示长的或短的DRX周期。最后的4个比特用于指示具体的DRX附加周期的长度。如图6所示。In the third way, the first 3 bits are used to indicate the number of DRX executions, for example, 000 is used to indicate a single DRX, 001 is used to indicate 2 DRXs, ...... and so on, until 111 is used to indicate 8 times DRX. The 4th bit is used to indicate long or short DRX cycle. The last 4 bits are used to indicate the length of a specific DRX additional cycle. As shown in Figure 6.
第四种方式，前2个比特用于指示DRX执行的次数，例如00至11表示多次，再采用第3个比特来指示单次DRX，如图7所示。在剩余的5个比特中，可以采用1个比特来指示长的或短的DRX周期，另4个比特来指示具体的DRX附加周期的长度。In the fourth way, the first 2 bits are used to indicate the times of DRX execution, for example, 00 to 11 indicate multiple times, and the third bit is used to indicate a single DRX, as shown in FIG. 7 . Among the remaining 5 bits, 1 bit can be used to indicate a long or short DRX cycle, and the other 4 bits can be used to indicate the length of a specific DRX additional cycle.
例如，如图6和图7中示出的情况，附加DRX命令的第2个字节中最后4个比特用来指示DRX附加周期，于是结合第4个比特信息位来分别表示对应于长的或短的DRX周期的长度的不同取值。For example, as shown in Figure 6 and Figure 7, the last 4 bits in the second byte of the additional DRX command are used to indicate the DRX additional cycle, and then the 4th bit information is combined to represent the corresponding long or different values of the length of the short DRX cycle.
举例说明如下，假设附加DRX命令指示短周期，并且后面的4个比特指示0001，如果从0000开始编号，则对应下面短DRX周期(shortDRX-Cycle)中的sf5，如果从0001开始编号，则对应下面短DRX周期(shortDRX-Cycle)中的sf2。长DRX周期偏移(longDRX-CycleStartOffset)也是同样的方法对应。以下给出了一个短DRX周期和长DRX周期偏移的例子。An example is as follows, assuming that the additional DRX command indicates a short cycle, and the following 4 bits indicate 0001, if the number starts from 0000, it corresponds to sf5 in the following short DRX cycle (shortDRX-Cycle), if the number starts from 0001, it corresponds to sf2 in the following short DRX cycle (shortDRX-Cycle). The long DRX cycle offset (longDRX-CycleStartOffset) is also corresponding in the same way. An example of a short DRX cycle and a long DRX cycle offset is given below.
需要说明的是，除了利用连接态DRX命令的预留信息位中的1个比特来指示eNB向UE发送的DRX命令是附加DRX命令还是连接态DRX命令的方式外，还可以在原有的连接态DRX命令的基础上直接扩展得到，例如可以使用新的LCID来全新构造一个附加DRX命令，构造方式与上述方式类似，此处不赘述。It should be noted that, in addition to using one bit in the reserved information bit of the connected state DRX command to indicate whether the DRX command sent by the eNB to the UE is an additional DRX command or a connected state DRX command, it can also be used in the original connected state Based on the DRX command, the DRX command can be directly extended. For example, a new LCID can be used to construct an additional DRX command. The construction method is similar to the above-mentioned method and will not be described here.
当UE收到附加DRX命令之后，UE立即进入睡眠状态，也就是从当前子帧的下一个子帧开始进入睡眠状态。并且在附加DRX命令指示的DRX周期执行结束后，UE被唤醒并仍然恢复到原有的连接态DRX机制：After the UE receives the additional DRX command, the UE immediately enters the sleep state, that is, enters the sleep state from the next subframe of the current subframe. And after the execution of the DRX cycle indicated by the additional DRX command ends, the UE is woken up and still returns to the original connected state DRX mechanism:
即对于执行单次DRX的UE而言，如果该UE收到附加DRX命令之前没有配置DRX参数，则仍然回到没有连接态DRX机制的状态；如果该UE收到附加DRX命令之前配置了DRX参数但是没有启动连接态DRX机制，则仍然恢复到没有启动连接态DRX机制的状态；如果该UE收到附加DRX命令之前配置了DRX参数并且启动了连接态DRX机制，则仍然恢复到原有的连接态DRX机制，即按照原有的连接态DRX机制的DRX参数执行睡眠状态。That is, for a UE performing a single DRX, if the UE has not configured DRX parameters before receiving the additional DRX command, it will still return to the state of no connected DRX mechanism; if the UE has configured DRX parameters before receiving the additional DRX command However, if the connected state DRX mechanism is not started, it will still return to the state where the connected state DRX mechanism has not been started; if the UE has configured DRX parameters before receiving the additional DRX command and started the connected state DRX mechanism, it will still return to the original connection The DRX mechanism in the connected state, that is, executes the sleep state according to the DRX parameters of the original connected state DRX mechanism.
即对于执行多次DRX的UE而言，如果该UE收到附加DRX命令之前配置了DRX参数但是没有启动连接态DRX机制，则仍然恢复到没有启动连接态DRX机制的状态。需要特别说明的是，如果执行多次优化的DRX的UE没有配置DRX参数，则无法执行多次优化的DRX，因为没有例如持续时间定时器等的定时器，UE不知道何时开始进入睡眠。并且，如果该UE收到附加DRX命令之前配置了DRX参数并且启动了连接态DRX机制，也不执行多次优化的DRX，以避免优化的DRX和原有的连接态DRX机制产生冲突。That is, for a UE that has performed DRX multiple times, if the UE has configured DRX parameters but has not started the connected state DRX mechanism before receiving the additional DRX command, it will still return to the state where the connected state DRX mechanism has not been started. It should be noted that if the UE performing multiple optimized DRX is not configured with DRX parameters, it cannot perform multiple optimized DRX, because there is no timer such as a duration timer, and the UE does not know when to start to sleep. Moreover, if the UE has configured DRX parameters and started the connected state DRX mechanism before receiving the additional DRX command, it will not perform optimized DRX multiple times, so as to avoid conflicts between the optimized DRX and the original connected state DRX mechanism.
由此可见，本发明实施例的DRX的方法能够解决UE在激活状态阶段中的空闲时间内无法更快速进入睡眠状态的问题，使得在不改变UE的现有DRX配置的前提下，在UE没有数据包发送或接收的小段空闲时间内通过附加DRX命令的触发执行新的睡眠模式，从而UE更加节电。It can be seen that the DRX method of the embodiment of the present invention can solve the problem that the UE cannot enter the sleep state faster during the idle time in the active state phase, so that without changing the existing DRX configuration of the UE, the UE does not A new sleep mode is triggered by an additional DRX command during the small idle period of data packet transmission or reception, so that the UE can save more power.
下面将结合图8和图9说明根据本发明实施例的DRX的装置的结构。The structure of the DRX apparatus according to the embodiment of the present invention will be described below with reference to FIG. 8 and FIG. 9 .
在图8中，非连续接收DRX的装置80包括确定单元81和发送单元82。其中，确定单元81用于确定在一个时间段内是否调度UE。如果确定单元81确定在一个时间段内不调度UE，发送单元82用于向UE发送附加DRX命令，该附加DRX命令用户指示UE在该一个时间段内执行DRX以处于睡眠状态。In FIG. 8 , an
例如，非连续接收DRX的装置80可以配置在基站中，确定单元81可以是处理器，发送单元82可以由接口实现。For example, the
在图9中，非连续接收DRX的装置90包括接收单元91和执行单元92。其中，接收单元91用于接收基站发送的附加DRX命令。执行单元92用于根据附加DRX命令的指示，在一个时间段内执行DRX以处于睡眠状态。In FIG. 9 , an apparatus 90 for discontinuous reception of DRX includes a receiving
此外，在图10中，非连续接收DRX的装置100还包括恢复单元93，用于在一个时间段内执行DRX以处于睡眠状态后，恢复初始工作状态；其中初始工作状态为连接态DRX工作状态、未启动DRX工作状态或无DRX工作状态。In addition, in FIG. 10, the
例如，非连续接收DRX的装置90、100可以配置在UE中，接收单元91可以是接口，执行单元92、恢复单元93可以由处理器实现。For example, the
其中，附加DRX命令可以包括用于指示DRX的执行时长的信息。Wherein, the additional DRX command may include information for indicating the execution duration of DRX.
可选地，附加DRX命令包括用于指示UE在一个时间段内执行DRX的次数的信息以及用于指示每次DRX的执行时长的信息。用于指示每次DRX的时长的信息包括用于指示UE采用长的或短的优化的DRX周期的信息以及长的或短的优化的DRX周期的时长的信息，其中长的或短的优化的DRX周期短于连接态DRX周期的激活状态阶段。Optionally, the additional DRX command includes information used to indicate the number of times the UE performs DRX within a period of time and information used to indicate the execution duration of each DRX. The information used to indicate the duration of each DRX includes information used to indicate that the UE adopts a long or short optimized DRX cycle and information about the duration of a long or short optimized DRX cycle, wherein the long or short optimized DRX cycle The DRX cycle is shorter than the active state phase of the connected state DRX cycle.
特别是，连接态DRX周期包括激活状态阶段和睡眠状态阶段，其中在激活状态阶段，UE监听物理下行控制信道，以便获取调度信息；在睡眠状态阶段，UE不监听物理下行控制信道。那么，一个时间段短于连接态DRX周期的激活状态阶段。In particular, the connected state DRX cycle includes an active state stage and a sleep state stage, wherein in the active state stage, the UE monitors the physical downlink control channel in order to obtain scheduling information; in the sleep state stage, the UE does not monitor the physical downlink control channel. Then, a period of time is shorter than the active state phase of the connected state DRX cycle.
本发明实施例的DRX的装置能够解决UE不被基站调度的空闲时间内无法更快速进入睡眠状态的问题，使得在不改变UE的现有DRX配置的前提下，在UE没有数据包发送或接收的小段空闲时间内通过附加DRX命令的触发执行新的睡眠模式，从而UE更加节电。The DRX device of the embodiment of the present invention can solve the problem that the UE cannot enter the sleep state more quickly during the idle time when the UE is not scheduled by the base station, so that without changing the existing DRX configuration of the UE, the UE does not send or receive data packets A new sleep mode is executed by triggering an additional DRX command in a small idle period, so that the UE can save more power.
