以下结合附图以及实施例,对本公开进行详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本公开,并不限定本公开。
图1是eDRX模式的工作耗电量示意图。eDRX通过延长idle态时终端醒来监听寻呼的周期,来达到节省电量的目的。传统的LTE(Long Term Evolution,长期演进)通常采用DRX机制来节省电量。DRX周期决定了省电的程度。例如:DRX周期为5.12s时比DRX周期为1.28s时省电。NB-IOT产品的应用领域通常是对时间延迟不敏感的场合,所以数据传输哪怕有所延迟,也是可以承受的。LTE定义的DRX周期通常都是在秒级。对于NB-IOT而言较为费电,所以NB-IOT引入了eDRX机制,通过将DRX周期延长到分钟,甚至小时级别,这样终端几分钟或者几小时才会醒来一次并尝试接受网络侧的寻呼。但是,由于网络侧配置不会在非PO(Paging Occasion,寻呼时机)时间寻呼终端,所以,在eDRX周期内,当非PO子帧时,下行寻 呼消息不会到达,终端处于浅度睡眠依旧耗电。
图2是现有PSM模式的工作机制示意图。PSM是进一步地节省电量的方式(可以理解为深度睡眠),在PSM模式下,终端保持注册的状态,不需要re-attach(重新附着),也不需要re-establish(重新建立)PDN(Public Data Network,公用数据网)连接。在整个Periodic(周期性)TAU(tracking area update,跟踪区域更新)周期内,完成附着(Attach)或者TAU之后,T3324s定时器运行,T3324s定时器运行的时间范围内按照eDRX周期性醒来尝试解码被叫业务,一旦T3324s定时器到时,终端进入PSM模式,如果终端不需要发送上行数据,终端基本可以等同于关机模式,如果网络有数据要发送给终端,终端是无法唤醒的,要等到终端进入连接态之后,终端才能够接收网络侧的下行数据,这样就会影响终端下行寻呼的可达率。
因此,目前,eDRX和PSM都不能达到理想的节电状态。
第一示例
本申请实施例提供一种监听寻呼消息的方法,执行主体为终端,该终端可以使NB-IOT终端。
图3是根据本公开第一示例的监听寻呼消息的方法的流程图。
步骤S301,激活eDRX模式和PSM模式。
步骤S302,根据eDRX模式的配置信息,确定eDRX周期和PSM周期中的寻呼时机。
eDRX周期是指eDRX模式的工作周期。PSM周期是指PSM模式的工作周期。在本示例中,eDRX周期和PSM周期都可以工作在eDRX模式和PSM模式,即eDRX模式和PSM模式在时间上交织运行。
在完成Attach或者TAU之后,接收网络侧发送的激活计时器Active Timer信息;Active Timer信息可以包括Active Timer的时长。其中,从Active Timer计时开始到计时结束,为eDRX周期;从Active Timer计时结束开始到Periodic TAU结束,为PSM周期。
eDRX周期的基本单位是超帧,而不是LTE中的帧,1超帧=1024帧。寻呼时机是为寻呼帧中的子帧。eDRX周期最多可以设置为10个超帧。如 果eDRX周期是10个超帧的话,那么换算为真实时间约为102.4s(1024*10*8=102400ms=102.4s),也就是约102.4s终端才会被唤醒并监听网络侧发送的信息,如寻呼消息。
图4为eDRX工作机制示意图,图4示出的eDRX周期为8个超帧的eDRX周期,寻呼帧位于PH(Paging Hyperframe,寻呼超帧)的PTW(Paging Transmission Windows,寻呼发送窗口)中,呼时机是为寻呼帧中的子帧。
寻呼时机PO是指网络侧发送寻呼消息的子帧。换而言之,寻呼时机是指网络侧发送寻呼消息的时间点。
根据eDRX模式的配置信息,可以确定eDRX周期中各个寻呼时机的时间点;根据eDRX周期中相邻两个寻呼时机的时间间隔,可以确定PSM周期中各个寻呼时机的时间点。其中,PSM周期中的相邻两个寻呼时机的时间间隔,PSM周期中的第一个寻呼时机和eDRX周期中的最后一个寻呼时机之间的时间间隔,都与eDRX周期中相邻两个寻呼时机的时间间隔相等。
步骤S303,在所述eDRX周期和PSM周期中,在寻呼时机到来时,进入业务模式并监听寻呼消息;如果监听到寻呼消息,则执行数据传输操作,如果没有监听到寻呼消息,则进入所述PSM模式。
在eDRX周期开始时进入eDRX模式,在寻呼时机到来时,从eDRX模式切换到业务模式,并判断是否监听到寻呼消息;如果监听到寻呼消息,则执行数据传输操作,并且在没有数据传输需求之后,从业务模式切换到PSM模式;如果未监听到寻呼消息,则从eDRX模式切换到PSM模式。此外,在本次数据传输之后,开始监听网络侧的下行数据,如果在第一预设时间段内没有监听到下行数据,则认为没有新的数据传输需求;如果在第一预设时间段内监听到下行数据,则认为存在新的数据传输需求,开始进行新的数据传输。
在进入PSM模式之后,在寻呼时机到来之前,判断Active Timer计时是否结束;如果Active Timer计时结束,则在寻呼时机到来时,从PSM模式切换到业务模式;如果计时未结束,则从PSM模式切换到eDRX模式,并在寻呼时机到来时,从eDRX模式切换到业务模式。此外,可以在距离寻呼时机到来的时间小于第二预设时间段时,判断Active Timer计时是否结束。
在执行本示例的过程中,根据完成附着Attach或者跟踪区域更新TAU的时间,检测本次周期性TAU是否已经到时;如果本次周期性TAU已经到时,则重新激活eDRX模式和PSM模式;如果本次周期性TAU尚未到时,则继续执行当前的操作。
在本示例中,采用eDRX模式和PSM模式时间交织的方式来保证在同时配置eDRX模式和PSM模式的情况下,在eDRX周期中抽出部分时间进入PSM模式,从而提高终端的节电效率,在PSM周期中的寻呼时机唤醒终端以便进行寻呼消息监听,增强终端的下行寻呼消息的可达效率,使终端能够有更好的数据传输效率。
第二示例
本示例结合图5~图7,对监听寻呼消息的方法进一步地进行描述。图5是根据本公开第二示例的监听寻呼消息的方法的流程图。图6是根据本公开第二示例的PO中未监测到寻呼消息的示意图。图7是根据本公开第二示例的PO中监测到寻呼消息的示意图。
步骤S501,激活eDRX模式和PSM模式。
将NB-IOT终端配置为工作在eDRX模式和PSM模式下。
步骤S502,接收网络侧发送的Active Timer信息并且确定寻呼时机。
在完成Attach或者TAU后,接收网络侧发送的Active Timer信息。Active Timer信息例如T3324的值。
根据eDRX模式的配置信息,确定网络侧可能发送寻呼消息的子帧,也就是寻呼时机PO,进而确定eDRX周期和PSM周期中的各个寻呼时机的时间点或者帧数目。
步骤S503,运行Active Timer并判断Active Timer是否到时;如果到时,则执行步骤S509;如果未到时,则执行步骤S504。
步骤S504,进入eDRX模式。
在Active Timer没有超时之前,进入eDRX模式的工作周期,即eDRX周期,在开始进入eDRX周期时,先进入eDRX模式,后续在没有数据传输需求的情况下,进入PSM模式,降低eDRX周期内终端的耗电量。
步骤S505,当寻呼时机到来时切换到业务模式并监听寻呼消息。
步骤S506,判断是否监听到寻呼消息;如果监听到寻呼消息,则执行步骤S507;如果未监听到寻呼消息,则执行步骤S509。
当终端处于PO所在的子帧时,终端会进入业务模式,并且尝试解码NPDCCH(Narrow Physical Downlink Control Channel,窄带物理下行控制信道),监测网络侧发送的寻呼消息;如果监听到寻呼消息,则表明网络侧有数据传输的需求,执行步骤S507,如果没有监听到寻呼消息,则表面网络侧暂时没有数据传输的需求,执行步骤S509。
如果当前Active Timer尚未超时,则在没有监听到寻呼消息的情况下,可以先进入eDRX模式并持续第三预设时间段之后,在执行步骤S509。
步骤S507,执行数据传输操作直到本次数据传输完成为止。
在监听到网络侧的寻呼消息之后,响应网络侧的寻呼消息,并且与网络侧建立数据链路和控制链路,以便进行数据传输。
步骤S508,判断在预设第一时间段是否有新的数据传输需求;如果有新的数据传输需求,则执行步骤S507;如果没有新的数据传输需求,则执行步骤S509。
当数据传输完毕,并且在传输完毕之后的第一时间段内,检测还有没有新的数据传输需求,例如:监听PDCCH信道是否有来自网络侧的下行消息,如果有,则有新的数据传输需求。
步骤S509,进入PSM模式。
步骤S510,在距离寻呼时机小于第二预设时间段时,判断Active Timer是否到时;如果到时,则执行步骤S505;如果未到时,则执行步骤S504。
如果Active Timer没有到时,则说明当前处于eDRX模式的工作周期,这样,在距离寻呼时机到来的时间小于第二预设时间段时,可以先从PSM模式切换到eDRX模式,在eDRX模式下,在寻呼时机到来时,从eDRX模式切换到业务模式,并通过监听寻呼消息来确定网络侧是否有数据传输需求。
如果Active Timer已经到时,则说明当前处于PSM模式的工作周期, 这时,在距离寻呼时机到来的时间小于第二预设时间段时,可以保持PSM模式,在寻呼时机到来时,从PSM模式切换到业务模式,并通过监听寻呼消息来确定网络侧是否有数据传输需求。
在执行本实施的过程中,根据Attach或者TAU完成的时间,判断从Attach或者TAU完成的时间开始到当前时间所经过的时间长度是否已经达到周期性TAU的时间长度;如果达到周期性TAU的时间长度,则执行步骤1,重新开始运行一个全新的周期;如果未达到周期性TAU的时间长度,则执行当前步骤。
本公开对于eDRX模式和PSM模式都被激活时的省电效率和寻呼可达性效率进行了综合优化,eDRX模式和PSM模式进行时间上的有效交织操作,在eDRX周期内,在没有数据传输需求的情况下进入PSM模式,在PSM周期内,在寻呼时机唤醒终端监听寻呼消息,进而提升了省电效率和寻呼可达率。
