[0012] 发明人在发明过程中注意到: [0012] The inventors have noted that in the process of the invention:

LTE系统对RRC状态进行了简化,只包括RRC_IDLE (空闲态)和RRC_C0NNECTED (连接态)两个状态,为了达到终端节电的目的,LTE在RRC_C0NNECTED状态下引入了DRX操作模式,即允许终端非连续监听PDCCH控制信道。 RRC state of the LTE system has been simplified to include only two RRCJDLE state (idle state) and RRC_C0NNECTED (connected state), in order to achieve the purpose of saving a terminal, LTE DRX operation mode is introduced in RRC_C0NNECTED state, i.e., the terminal is allowed discontinuous monitoring the PDCCH control channel.

[0013] 协议中针对小区间切换和DRX的监听设置了多个计时器,这就需要保证终端切换计时器和终端DRX连续监听计时器保持一致,即在终端切换过程中,终端必须处于连续监听状态,即非DRX状态,且切换计时器必须不超时,否则会导致切换失败。 [0013] protocol for inter-cell handover and the monitor are provided a plurality of DRX timers, which requires the terminal to ensure that the timer switch and a terminal continuously listens DRX timer consistent, i.e. the handover process in the terminal, the terminal must be continuously listening state, ie non-DRX state, and must not switch timer expires, otherwise it will lead to switch failure. 然而,非DRX状态的计时器有多个,并且都是根据空口情况随时启动的,因此,为了保证与切换计时器保持一致,就需要RRC和MAC频繁的进行交互,而这将给eNB带来了很大的处理负荷,并且因为交互存在时延,也会造成控制不准确而导致终端切换失败。 However, the timer has a plurality of Non-DRX state, and in accordance with the air interface are initiated at any time, therefore, in order to ensure consistency with the timer switch, it requires frequent interaction RRC and the MAC, which will bring eNB a large processing load, and because of the delay interaction, it can also cause the control terminal lead to inaccurate handover failure.

[0014] 鉴于此,有必要考虑在终端需要切换时RRC通知给MAC,MAC层对终端DRX状态进行准确监控,然后根据切换过程中各种计时器的控制复杂度,MAC通知RRC发起关闭或者开启终端的DRX操作,或者继续维持正在进行的DRX处理,从而来降低RRC和MAC之间消息的交互,解决DRX造成的终端切换失败的问题。 [0014] In view of this, it is necessary to consider the need to switch the terminal RRC informs the MAC, MAC layer of the terminal to monitor accurately the DRX state, then the handover process according to the complexity of the control of various timers, the MAC notifies RRC initiates close or open DRX operation of the terminal, or continue to maintain DRX ongoing process, thereby reducing the interaction between the RRC message and the MAC of the terminal to solve the problem caused by DRX handover failure.

[0015] 因此,本发明实施例中提供了基于空口切换时延的DRX使用方案,该方案中,当终端发起切换时,eNB的RRC通知MAC,然后MAC根据终端的DRX各种计时器的状态,并结合T304计时器的取值,确定是否取消、开启或者维持DRX已有处理,只有在需要取消或者开启DRX时,MAC才通知RRC,RRC发起终端的DRX参数重配置。 [0015] Accordingly, embodiments of the present invention provides a DRX scheme based air interface handoff delay, this scheme, when the terminal initiates handover, the RRC notifies the eNB MAC, MAC then the state of the various DRX timers terminal and when combined with the value of timer T304, to determine whether to cancel, open or maintain existing DRX process, only if you want to cancel or turn DRX, MAC before notifying RRC, RRC initiating terminal DRX parameter reconfiguration.

[0016] 下面结合附图对本发明的具体实施方式进行说明。 [0016] DETAILED DESCRIPTION OF THE DRAWINGS Embodiment of the present invention will be described.

[0017] 图1为DRX处理方法实施流程示意图,如图所示,基站在进行DRX处理时可以包括如下步骤: [0017] FIG. 1 is a schematic flow chart of embodiment DRX processing method, as shown, the base station may include the steps of performing the DRX processing:

步骤101、当终端发起切换时,RRC确定该终端是否开启DRX ; 步骤102、在该终端开启DRX时,RRC通知MAC计时器T304的计时状态; 步骤103、MAC根据该终端DRX的相关计时器参数及所述计时器T304的计时状态确定DRX的状态,以使该终端在切换过程中处于非DRX状态,且切换计时器不超时。 Step 101, when the terminal initiates handover, the terminal determines whether the RRC DRX opening; step 102, DRX when the terminal is turned on, the state of the RRC notifies MAC timer T304; a step 103, the timer associated MAC DRX parameters based on the terminal's state and the timer T304 DRX status determined so that the terminal is in the non-DRX state during the handover, and the handover timer is not timed out.

[0018] 具体的,当终端需要进行切换时,RRC通知MAC,并携带T304计时器的计时状态, MAC根据控制的终端DRX的相关计时器参数,并结合RRC的T304计时器,对终端的DRX使用进行决策,然后根据决策结果决定是否需要通知RRC对终端的DRX参数进行重配置。 [0018] Specifically, when the terminal needs to handover, RRC notifies the MAC, and carries a running state of the timer T304, the MAC according to the relevant parameters of the terminal timer of the DRX control, combined with a timer T304, RRC, DRX for the terminal use to make decisions, and then decide whether to notify RRC DRX parameter of the terminal reconfiguration decisions based on the results.

[0019] 并且,在该过程中RRC与MAC之间交互很少,因此不会给eNB带来很大的处理负荷;同时,通过eNB侧的RRC和MAC的交互,共同完成切换过程的DRX控制,也解决了切换过程中DRX的非连续监听PDCCH可能导致切换失败的问题。 [0019] Further, in the process little interaction between the RRC and MAC, and therefore not a great deal of processing load to the eNB; Meanwhile, the eNB through RRC and MAC interaction side, together to complete the handover procedure DRX control , but also solve the problem of non-continuous DRX monitors the PDCCH may lead to failure of switched handover process.

[0020] 实施中,当RRC准备给终端发送小区切换的命令时,需要对是否需要通知MAC相关的切换参数进行判断,也即,当终端发起切换时,RRC需要确定该终端是否开启DRX,具体的确定可以包括以下方式之一或者其组合: [0020] embodiment, when the RRC is ready to send a command cell for the handover to the terminal, it is necessary to need to notify MAC-related handover parameter determination, i.e., when the terminal initiates handover, RRC is determined whether the terminal is turned on the DRX, particularly the determination may comprise one of the following ways, or a combination thereof:

1、根据终端重配置无线链路信息中是否携带了DRX参数来确定该终端是否开启DRX。 1, the terminal radio link reconfiguration message according to whether it carries the DRX parameters to determine whether the terminal is turned on DRX.

[0021] 具体的,终端是否开启了DRX控制,可以以终端重配置无线链路信息中是否携带了DRX参数为标准,如果携带了,则意味着终端已经开启DRX。 [0021] Specifically, the DRX control terminal is turned on, the terminal may be a radio link reconfiguration information, whether it carries the DRX parameters as the standard, if carried, it means that the terminal is turned on DRX. 如果终端开启了DRX,则需要通知MAC,参数包括主要T304剩余的时长,通过该剩余时长,MAC可以判断是否需要申请对终端的DRX参数进行重配置。 If the terminal is turned DRX, the MAC notification is required, the parameters including the length of the remaining primary T304, passes through the remaining length, it can determine whether to apply the MAC DRX parameters for reconfiguration of the terminal.

[0022] 2、根据空口质量及终端是否开启了DRX控制来确定该终端是否开启DRX。 [0022] 2. The mass of the air interface and the DRX control terminal is turned on to determine whether the terminal is turned on DRX.

[0023] RRC接收的终端的测量消息中反映的空口质量,如果空口质量非常差,且终端开启了DRX控制,则需要通知MAC。 [0023] The air interface quality measurement terminal RRC message received reflected, if the air interface quality is very poor, and the terminal opened DRX control, the need to inform MAC. 实施中,空口质量是否差的判决可以根据需要或者参照别的标准来确定。 Embodiment, the poor quality of the air interface if the judgment may need to be determined with reference or other criteria.

[0024] 具体的,是因为空口质量差会引起UE发起小区重选,进行切换。 [0024] Specifically, the air interface because of poor quality will cause the UE initiates a cell reselection, handover. 所以在此种情况下,RRC要及时通知MAC,MAC根据掌握的UE的DRX信息,判决是否需要关闭DRX。 So in this case, RRC to promptly notify the MAC, MAC DRX based on available information of the UE, the decision whether to close the DRX. 如果UE 没有开启DRX控制,尽管空口质量差,也不需要通知MAC。 If the UE DRX control is not turned on, despite poor quality of the air interface, you do not need to notify the MAC.

[0025] 3、根据DRX控制是否关闭来确定该终端是否开启DRX。 [0025] 3. The DRX control is off to determine whether the terminal is turned on DRX.

[0026] 其他一些性能需要,比如为了减少终端小区的切换时延(无论是否MAC进行了申请),直接关闭DRX控制,以避免DRX可能带来的时延。 [0026] Other performance requirements, such as cell terminals in order to reduce the switching delay (whether made apply MAC), directly off the DRX control, to avoid the delay caused by DRX possible. 这是因为关闭了DRX,则UE就一直处于连续监听状态,即非DRX状态。 This is due to the closure of the DRX, the UE has been in continuous listening state, that is, non-DRX state.

[0027] 实施中,对于源小区MAC是否需要发起DRX参数重配置申请,MAC控制着终端的DRX状态,结合T304的剩余时长(本申请简称T304)对是否发起DRX参数重配置申请的判决。 [0027] embodiment, with respect to whether or not the source cell MAC needs to be initiated DRX parameter reconfiguration request, MAC control terminal of the DRX state, in conjunction with the remaining duration T304 (in this application referred to as T304) of whether to initiate DRX parameters reconfiguration request judgment. 也即,MAC根据该终端DRX的相关计时器参数及所述计时器T304的计时状态确定DRX 的状态的实施,可以包括以下方式之一: That is, according to the MAC-related parameter and the timer status of the timer T304 DRX, the terminal determines the DRX status of embodiments may include one of the following:

[0028] 具体的,当终端只有onDurationTimer (持续时间定时器)、shortDRX-Cycle (DRX 短周期)、IongDRX-Cycle (DRX长周期)、drxShortCycleTimer (DRX短周期定时器)这些计时器在运行时: [0028] Specifically, the terminal only when the onDurationTimer (duration timer), shortDRX-Cycle (DRX short cycle), IongDRX-Cycle (DRX cycle length), drxShortCycleTimer (DRX short cycle timer) during operation of these timers:

如果T304 >= 11*10叫01«-07(;16,其中权已{1,2,3,•.…}时,MAC不需要发起DRX参数 If T304> = 11 * 10 called 01 «-07 (; {. 1,2,3, • ...} 16, which has the right, required to initiate the MAC DRX parameters

[0030] 2、当终端drx-RetransmissionTimer 禾口drx_InactivityTime 在运ίΐ 时,如果Τ304 > n*T,MAC 重启DRX,如果T304 <= n*T,MAC 关闭DRX,其中, [0030] 2, when the terminal drx-RetransmissionTimer Wo port drx_InactivityTime in transit ίΐ, if Τ304> n * T, MAC restart the DRX, if T304 <= n * T, MAC close the DRX, wherein

T = rnax{drx-Retransmission,drx- Inactivit/Time} ' WE {1,2,3,.....} T = rnax {drx-Retransmission, drx- Inactivit / Time} 'WE {1,2,3, .....}

[0032] 如果T304 <= n*T,其中《e {1,2,3,..…}吋,MAC需要发起DRX参数重配置申请, [0032] If the T304 <= n * T, where "e {1,2,3, .. ...} inch, required to initiate the MAC DRX parameters reconfiguration request,

也即,关闭DRX,等到终端切换到目的小区后再重新开启。 That is, the DRX closed, until the terminal switches to cell object reopen.

[0033] 实施中,还可以进一步包括:MAC根据需要确定DRX的状态。 [0033] In embodiments, it may further comprise: MAC DRX status determination as required.

[0034] 具体实施中,如果遇见其他情况,MAC也可以直接启动关闭DRX的申请。 [0034] In particular embodiments, if the other conditions met, the MAC may start off DRX application directly. 或者在当MAC需要发起申请时,向RRC发送申请消息。 When the MAC or application needs to be initiated, sent to the RRC request message. MAC并不必仅限于根据相关计时器参数及计时器T304来确定DRX的状态。 The MAC is not necessarily limited to be determined according to the relevant DRX parameter and timer T304 timer status. 这是因为定时器的方式只是一种可以量化的控制方式,但还存在其他的需要MAC确定DRX的状态的情况,比如:如果切换过程中信令被丢失,重传了几次后仍然无法被正确接收,MAC可以发起关闭DRX等等。 This is because the timer is just a way of quantifiable control, but there are other situations need to determine the status of DRX MAC, for example: if the signaling is lost during switching, retransmission of the few times still can not be correctly received, MAC may initiate closed DRX like. 因此,实施中,MAC也可以根据需要或者别的情况自行确定DRX的状态,而不用囿于仅根据定时器决定DRX状态。 Thus, in the embodiment, the MAC DRX status may also be determined according to their own needs or other circumstances, rather than confined to only determined DRX status according to a timer.

[0035] 实施中,在确定DRX的状态为取消或者开启DRX时,还可以进一步包括: MAC通知RRC发起该终端的DRX参数重配置,并通知RRC重配置DRX所需参数。 [0035] In the embodiment, when DRX canceled or turn, may further include a DRX status determination: MAC DRX parameters initiated notification RRC reconfiguration of the terminal, and notifies the RRC reconfiguration desired DRX parameter.

[0036] 实施中,RRC发起该终端的DRX参数重配置的过程按协议规定好的信令流程实施即可,只是实施中该信令流程的启动是由MAC通知的。 [0036] In embodiments, the process of initiating the RRC DRX parameters of the terminal of the reconfiguration procedure according to a signaling protocol specified embodiments can be good, but the embodiment of the signaling flow is started by the MAC notification.

[0037] 实施中,在确定DRX的状态为取消或者开启DRX时,还可以进一步包括: MAC向该终端切换目的小区的MAC提供DRX控制参数状态。 [0037] In embodiments, when DRX canceled or turn, may further include a DRX status determination: MAC to the terminal of the handover destination cell provides MAC DRX control parameter status.

[0038] 下面以实例来进行说明。 [0038] In examples to be described below.

[0039] 图2为LTE中自适应于小区间切换时延的eNB DRX控制实施流程示意图,如图所示,当终端上报测量后,RRC准备发起终端小区间切换时,可以包括如下步骤: [0039] Figure 2 is adaptive to the LTE inter-cell handoff delay eNB DRX schematic flow chart of a control embodiment, as shown, when the terminal reports a measurement, the RRC initiates prepared handover between terminals in the cell, may comprise the steps of:

步骤201、RRC发起终端切换流程,并根据DRX是否启动判决是否需要通知源小区的 Step 201, RRC handover originating terminal process, and whether to notify the source cell DRX start judgment according to whether

MAC。 MAC.

[0040] 实施中,RRC可以根据终端能力,并根据终端建立的相关信息,判断终端是否开启了DRX特性,如果开启,RRC通知源小区的MAC终端的切换流程已经启动,并把T304计时器最新的当前值(包含内部处理时延)通知给源小区MAC。 [0040] In embodiments, depending on the terminal RRC capability, and based on information terminal established, the terminal determines whether to open the DRX feature, if enabled, the handover procedure the source RRC notifies the MAC cell terminal has started, and the timer T304 Latest the current value (containing internal processing delay) the source cell notifies the MAC.

[0041] 步骤202、源小区MAC按照DRX参数控制的用户状态,并结合T304进行DRX控制判决。 [0041] Step 202, the source cell DRX MAC parameter control according to the user status and perform binding T304 DRX control decision.

[0042] 步骤203、确定终端是否需要关闭或重启DRX,是则转入步骤205,否则转入步骤204。 [0042] Step 203, it is determined whether the terminal needs to shut down or restart the DRX, the process proceeds to a step 205, otherwise proceeds to step 204. [0043] 实施中,源小区MAC接收到切换的信令后,根据终端当前的DRX状态,判决是否需要对终端的DRX状态进行重配置(关闭或者重启),如果不需要,执行步骤204,源小区的MAC 继续目前已有的处理流程,继续进行终端的DRX状态,切换时准备向目的小区数据倒换;否则,进行步骤205; After the [0043] embodiment, the received MAC source cell handover signaling, according to the current DRX status of the terminal, the decision whether to re-configure (off or reset) terminal of the DRX state, if not, step 204, the source MAC cell present, continue processing flow, the terminal continues the DRX state, data ready switching to a handover target cell; otherwise, step 205;

步骤204、源小区MAC继续已有处理。 Step 204, the source cell continues existing MAC process.

[0044] 步骤205、通知RRC进行终端的DRX参数重配置;切换时小区的MAC向目的小区的MAC提供DRX控制参数状态,以保证两个小区下UE的DRX状态的同步。 [0044] Step 205, the terminal notifies the RRC reconfiguration DRX parameter; cell switched MAC DRX control parameters to provide the synchronization state to ensure that the DRX status of the UE in the two cells to a MAC destination cell.

[0045] 实施中,源小区MAC通知RRC需要重配置终端的DRX参数;并准备DRX控制参数状态的切换倒换,以保持源小区和目的小区中终端DRX状态的连续性控制。 [0045] In embodiments, MAC notification source cell DRX parameter required RRC reconfiguration of the terminal; and control parameter switching handover preparation DRX state, to maintain the continuity of control cell and the target cell DRX state in the terminal.
