Description

一种LTE下调整DRX参数的方法和系统 技术领域
本发明涉及无线通信技术领域,更具体地,本发明涉及一种LTE下调整DRX参数的方法和系统。
背景技术
LTE中,为了解决终端耗电量大的问题,提出了DRX(DiscontinuousReception,非连续接收)。UE(User Equipment,用户终端)在一段时间里停止监听PDCCH(Physical Downlink Control Channel,物理下行控制信道)信道,来达到省电的目的。
DRX分为两种,IDLE DRX,即UE处于IDLE状态下的DRX,由于处于IDLE状态时,UE只要监听呼叫信道与广播信道,只要定义好固定的周期,就可以达到非连续接收的目的;ACTIVE DRX,即UE处在RRC-CONNECTED状态下的DRX,UE通过一段时间内停止监听PDCCH,来达到省电的目的,同时由于可以优化系统资源配置,更重要的是节约手机功率,而不需要通过让手机进入到RRC_IDLE模式来实现,例如一些非实时应用,如web浏览,即时通信等,总是存在一段时间,手机不需要连续监听下行数据以及相关处理,DRX就可以应用到这样的情况,另外由于这个状态下依然存在RRC连接,因此UE要转到支持状态的速度非常快。
UE的DRX周期分为激活期和睡眠期,UE的业务不断变化,如果长时间使用一组固定的DRX参数,就可能不合适。如果睡眠期过长,虽然UE省电效果好,但是UE会出现大延时,影响用户体验;如果激活期过长,虽然可以避免UE出现大延时,但是DRX省电效果不明显。

步骤S4、根据步骤S3中的OnDuration Timer调整方案,确定DRX参数的调整方案。
如果OnDuration Timer长度被调整,且调整后的OnDuration Timer长度/原长度>Th4,减小DRX周期长度;
如果OnDuration Timer长度被调整,且调整后的OnDuration Timer/原长度 <=Th5,增加DRX周期长度;
否则,其他情况下不调整DRX周期长度。其中,Th4、Th5为预先设定的阈值,且Th5<Th4。OnDuration Timer原长度指的是当前DRX周期长度初始对应的OnDuration Timer长度。
本发明所述的一种LTE下调整DRX参数的方法,一个DRX周期内Inactivity Timer(闲置定时器)启动次数反映了UE被调度频率,以此作为DRX参数调整的依据,使调整后的参数能够适应当前UE调度情况,有利于如果调度频率过高或过低,激活期就应该进行调整,从而避免激活期过长导致省电效果不明显,或者激活期过短导致的UE延时大,影响用户体验;OnDuration Timer(持续定时器)是基站给UE配置的固定激活期,Inactivity Timer(闲置定时器)可以动态延长激活期,当UE被调度频率改变时,调整OnDuration Timer和Inactivity Timer,改变激活期长度,有利于避免激活期过长导致省电效果不明显,或者激活期过短导致的UE延时大的情况;一个DRX周期内,激活期以外的时间都属于非激活期,当UE被调度频率低而多次减小UE激活时间时,也可以通过增加DRX周期来达到增加非激活期省电的目的。可见,本发明能够解决当UE业务变化时,存在的DRX参数配置不合理的问题。
在本方案中,优选地,所述Th1=0,Th2=6,Th3=9;所述Th5=1/3,Th4=3。
在本方案中,调整OnDuration Timer长度按照协议中取值列表顺序进行调整,若当前OnDuration Timer取值为列表中Index=2对应的值,增加长度时选择Index=3对应的值,减小长度时选择Index=1对应的值。如果待调整值已经达到上限或下限而无法调整时,不做处理。同样的,调整Inactivity Timer的长度也是同样的方法。

统计单元,用于基站侧在每个DRX周期起始点将T1清0后,开始统计该周期内Inactivity Timer启动次数T1,进入下一单元;
第一调整单元,用于DRX周期结束后,根据统计单元统计的T1的值,确定OnDuration Timer的调整方案;
所述第一调整单元,具体用于如果T1≤TH1,减小OnDuration Timer和Inactivity Timer长度,进入第二调整单元;如果Th3>=T1>Th2,增加OnDuration Timer和Inactivity Timer长度,进入第二调整单元;如果T1>Th3,直接减小DRX周期,OnDuration Timer和Inactivity Timer的长度不变,流程结束;如果Th2>=T1>Th1,不调整OnDuration Timer和Inactivity Timer的长度,流程结束;其中,Th1、Th2、Th3为预先设定的阈值,且Th1<Th2<Th3。
第二调整单元,用于根据第一调整单元中的OnDuration Timer调整方案,确定DRX参数的调整方案。
所述第二调整单元,具体用于如果OnDuration Timer长度被调整,且调整后的OnDuration Timer长度/原长度>Th4,减小DRX周期长度;如果OnDuration Timer长度被调整,且调整后的OnDuration Timer长度/原长度≤Th5,增加DRX周期长度;否则,其他情况则不改变DRX周期长度;其中,Th4、Th5为预先设定的阈值,且Th5<Th4。
优选地,所述Th1=0,Th2=6,Th3=9;所述Th5=1/3,Th4=3。
在本方案中,调整OnDuration Timer长度按照协议中取值列表顺序进行调整,若当前OnDuration Timer取值为列表中Index=2对应的值,增加长度时选择Index=3对应的值,减小长度时选择Index=1对应的值,如果待调整值已经达到上限或下限而无法调整时,不做处理;同样的,调整Inactivity Timer的长度也是同样的方法。
调整DRX周期长度按照协议中取值列表顺序进行调整,若当前DRX取值为 列表中Index=2对应的值,增加长度时选择Index=3对应的值,减小长度时选择Index=1对应的值,如果待调整值已经达到上限或下限而无法调整时,不做处理。
综上所述,本发明提出了一种周期性动态调整DRX参数的方案,应用本发明可以根据UE的数据量和被调度情况来调整DRX参数,较好地避免了因为UE被调度情况变化而导致的DRX参数不合理,UE出现较大延时或者省电效果不好的问题,更大程度上实现了DRX省电的目的。
以上所述实施例及应用场景仅为本发明的较佳实施例及应用场景而已,并不用以限制本发明,凡在本发明的精神和原则之内所作的任何修改、等同替换和改进及其在其他领域及场景的应用,均应包含在本发明的保护范围之内。
