Description

一种寻呼方法及设备 技术领域
本发明涉及通信技术领域,具体涉及一种寻呼方法及设备。
背景技术
机器对机器(M2M,Machine to Machine)是机器与机器之间通过无线网络相互传递信息和数据的简称,又被称为机器类型通信,它是移动通信下一步发展的重要方向。在机器类型通信中,基站可以向空闲状态和连接状态的用户设备(UE,User Equipment)发送寻呼消息,该寻呼消息可以用于通知UE系统信息更新以及通知UE接收地震、海啸预警系统(ETWS,Earthquake and Tsunami Warning System)或商业移动告警服务(CMAS,Commercial Mobile Alert Service)等信息。
当前,基站在非连续性接收寻呼周期内的寻呼时刻(PO,Paging Occasion)向UE发送对应的寻呼消息,其中,基站在一个PO内发送的寻呼消息可以包括基站对多个UE的寻呼消息,即多个UE可以共享一个PO,且包括一个或多个PO的无线帧被称为寻呼帧(PF,Paging Frame)。在一个非连续性接收寻呼周期内,计算出PF和PO的具体位置后,UE在相应的PO内监测物理下行控制信道(PDCCH,Physical Downlink Control Channel),若UE在相应的PO内监测到寻呼无线网络临时标识(P-RNTI,Paging Radio Network Tempory Identity),UE则根据PDCCH指示的无线承载(RB,Radio Bearer)分配以及调制编码方式从该PO内的物理下行共享信道(PDSCH,Physical Downlink Shared Channel)上获取相应的寻呼消息。
为了满足M2M系统的低功耗、低复杂性以及深覆盖的需求,一种新的接入技术被引入,且这种新的接入技术的特点是系统宽带非常窄,其中,为了满足M2M低功耗的需求,对该新的接入技术中的物理层帧的帧结构做了新的设置,且新设置的物理层帧由超高帧组成,其中,一个超高帧由2的幂次方个无线超帧组成,一个无线超帧由2的幂次方个无线帧组成,但是对于使用该新设 置的物理层帧的M2M系统,现有技术中没有提供相关的寻呼技术,导致其无法满足对于下行业务的支持。

本发明实施例公开了一种寻呼方法及设备,提供了一种针对新设置的物理层帧的寻呼方法,满足了基站对于下行业务的支持且降低了基站与用户设备的功耗。以下分别进行详细说明。

本发明实施例中,当第一位置标识为无线帧标识时,即当基站将用户设备的寻呼消息承载在无线帧中时,基站可以预先在一个无线超帧内设置一些固定位置的无线帧以作为承载寻呼消息的无线帧,且该一些固定位置的无线帧的无线帧标识可以形成一个固定无线帧标识集合,公式(4)计算出来的无线帧标识I_S2的值为上述固定无线帧标识集合的子集。
本发明实施例中,由于基站针对不同覆盖范围等级的用户设备发送下行消息的能力不同,因此,对于与覆盖程度较好的用户设备对应的寻呼信道,为了降低每个下行控制信息间隔的寻呼负荷,基站在更多的下行控制信息间隔上发送寻呼消息,而对于与覆盖程度较差的用户设备对应的寻呼信道,由于基站需要多次在对应寻呼信道发送寻呼消息,这导致了基站发送寻呼消息的效率很低,因此,基站为不同覆盖范围等级的寻呼信道设置不同的承载寻呼消息的下行控制信息间隔的个数,即与覆盖范围等级为i寻呼信道设置的承载寻呼消息的下行控制信息间隔的个数为Nsi,且i的取值为0表示正常覆盖范围等级,i的取值大于0表示扩展覆盖范围等级,且作为一种可选的实施方式,Nsi的取值范围可以如下所示:

此外,多个覆盖范围等级的用户设备可以共享一个寻呼信道,即该被共享的寻呼信道对应多个下行控制信息间隔长度,则该被共享的寻呼信道中用于承载寻呼消息的下行控制信息间隔的个数Nmix的取值范围为{1,2,…L},其中,L表示该被共享的寻呼信道中每个覆盖范围等级对应的下行控制信息间隔的个数之和,且与Nmix个下行控制信息间隔对应的寻呼位置可以以位图文件(Bitmap)的形式体现,也可以以协议规定的其它形式体现,本发明实施例不做限定。
以与Nmix个下行控制信息间隔对应的寻呼位置以位图文件的形式体现为例,假设共享一个寻呼信道的覆盖范围等级分别为覆盖范围等级0(正常覆盖范围等级),覆盖范围等级1及覆盖范围等级2(最大覆盖范围等级),且覆盖范围等级2的DCI interval_class i2是正常覆盖范围等级DCI interval_class 0的32倍,覆盖范围等级1的DCI interval_class i1是正常覆盖范围等级DCI interval_class 0的4倍,且使用“1”来指示下行控制信息间隔中承载有寻呼消息,则具体的位图文件设计如下:
一、覆盖范围等级2的下行控制信息间隔对应的寻呼位置的位图是:10000000 0000 0000 0000 0000 0000 0000;
二、该被共享的寻呼信道中针对覆盖范围等级1的用户设备的最大寻呼次数为8。当寻呼次数为8时,下行控制信息间隔对应的寻呼位置的位图是:10001000 1000 1000 1000 1000 1000 1000;当寻呼次数为5时,下行控制信息间隔对 应的寻呼位置的位图是:1000 0000 0000 1000 0000 1000 1000 1000。
三、该被共享的寻呼信道中针对覆盖范围等级0的用户设备的最大寻呼次数为32。当寻呼次数为32时,下行控制信息间隔对应的寻呼位置的位图是:11111111 1111 1111 1111 1111 1111 1111;当寻呼次数为18时,下行控制信息间隔对应的寻呼位置的位图是:1100 1011 1110 0000 1100 1010 1100 1111。
假设基站用3*32bit=96bit来表示该被共享的寻呼信道上的寻呼配置,则以上述三种位图示例为例,若该被共享的寻呼信道中用于承载覆盖范围等级0的用户设备的寻呼消息的下行控制信息间隔个数为18,用于承载覆盖范围等级1的用户设备的寻呼消息的下行控制信息间隔个数为5且用于承载覆盖范围等级2的用户设备的寻呼消息的下行控制信息间隔个数为1时,则该被共享的寻呼信道中用于承载寻呼消息的下行控制信息间隔的个数Nmix为22。
本发明实施例中,假设新设置的物理层帧的帧结构如图8所示,则下行控制信息间隔长度(又称下行控制信息调度周期,且其单位为无线帧)的取值范围可以为{80ms,160ms,320ms,640ms,1280ms,2048ms,2560ms,5120ms}集合的全集或任意一个子集,且当正常覆盖范围等级的下行控制信息间隔长度为上述集合中的子集时,扩展覆盖范围等级的下行控制信息间隔长度的取值范围为{80ms,160ms,320ms,640ms,1280ms,2048ms,2560ms,5120ms}*{1,2,3,4…64}的任意一个子集。

本发明实施例中,当步骤S502中的第一位置标识为下行控制信息间隔标识时,目标位置为下行控制信息间隔标识对应的下行控制信息间隔;当步骤S502中的第一位置标识为无线帧标识时,目标位置为无线帧标识对应的无线帧,即基站可以将寻呼消息承载在物理层帧的某一无线超帧中的某一无线帧中以获取承载有寻呼消息的物理层帧,也可以将寻呼消息承载在物理层帧的某一无线超帧中的某一下行控制信息间隔中以获取承载有寻呼消息的物理层帧,本发明实施例不做限定。
本发明实施例中,作为一种可选的实施方式,寻呼消息可以包括寻呼消息 列表以及消息变更指示,其中,寻呼消息列表包括基站需要寻呼的每个用户设备的用户设备标识以及每个用户设备的寻呼域的全部或部分内容,即寻呼消息可以包括基站对一个或多个用户设备的寻呼消息,不同的用户设备的用户设备标识不同,且寻呼域包括分组交换域或电路交换域。
本发明实施例中,作为另一种可选的实施方式,寻呼消息可以包括至少两个组寻呼列表,以及包括消息变更指示和每个组寻呼列表的列表标识,每个组寻呼列表包括该组寻呼列表内用户设备的用户设备标识以及对应的寻呼域,其中,不同的用户设备的用户设备标识不同。
本发明实施例中,上述消息变更指示可以包括系统消息变更指示、地震及海啸预警系统变更指示、商业移动告警服务变更指示以及扩展接入禁止参数变更指示中的至少一种。
本发明实施例中,作为一种可选的实施方式,下行控制信息间隔可以包括用于承载寻呼消息的数据部分,即基站在确定出无线超帧以及该无线超帧中用于承载寻呼消息的下行控制信息间隔后,基站直接将寻呼消息承载在该下行控制信息间隔中。举例来说,如图9所示,图9是本发明实施例公开的一种寻呼消息的下行控制信息调度示意图,如图9所示,无论在正常覆盖范围等级下还是在扩展覆盖范围等级下,下行控制信息间隔只包括用于承载寻呼消息的数据部分。
本发明实施例中,作为另一种可选的实施方式,下行控制信息间隔可以包括下行控制信息调度部分以及用于承载寻呼消息的数据部分,其中,下行控制信息调度部分承载寻呼消息的第二位置标识,第二位置标识用于指示寻呼消息在数据部分的时频资源位置。可选的,下行控制信息调度部分还可以承载有寻呼消息的寻呼无线网络临时标识,寻呼无线网络临时标识用于指示下行控制信息间隔中承载有寻呼消息。本发明实施例中,寻呼无线网络临时标识是协议中定义的长度为从1bit到20bit,甚至更大bit的固定值,且第二位置标识可以通过寻呼信道标识(如寻呼信道号等)、起始传输时间以及传输时长确定,也可以通过传输资源大小确定,本发明实施例不做限定。
本发明实施例中,上述下行控制信息调度部分可以包括固定下行控制信息 部分以及可变下行控制信息部分,且可变下行控制信息部分的长度可以由基站寻呼的用户设备的数量决定,寻呼消息的寻呼无线网络临时标识以及寻呼消息在数据部分中的第二位置标识既可以承载在固定下行控制信息部分,又可以承载在可变下行控制信息部分,本发明实施例不做限定。举例来说,假设基站基于下行控制信息的调度示意图如图10所示,图10是本发明实施例公开的一种下行控制信息的调度示意图,图10包括正常覆盖范围等级的用户设备的下行控制信息调度以及扩展覆盖范围等级的用户设备的下行控制信息调度,如图10所示,在正常覆盖范围等级下,无线超帧M包括64个无线帧,且每4个无线帧组成一个包括固定下行控制信息部分、可变下行控制信息部分以及数据部分的下行控制信息间隔(其长度为320ms),其中,固定下行控制信息部分的长度为60ms且在固定下行控制信息部分承载有寻呼消息的寻呼无线网络临时标识以及寻呼消息的第二位置标识,在扩展覆盖范围等级下,无线超帧M包括64个无线帧,且该64个无线帧组成了包括固定下行控制信息部分、可变下行控制信息部分以及数据部分的下行控制信息间隔(其长度为5120ms),其中,固定下行控制信息部分的长度为960ms且在固定下行控制信息部分承载有寻呼消息的寻呼无线网络临时标识以及寻呼消息的第二位置标识。
针对图10所示的下行控制信息的调度示意图,如图11所示,图11是本发明实施例公开的另一种寻呼消息的下行控制信息调度示意图,如图11所示,下行控制信息间隔的数据部分承载寻呼消息,下行控制信息间隔的下行控制信息调度部分的固定下行控制信息部分可以包括寻呼消息的第二位置标识,可选的,该固定下行控制信息部分还可以包括寻呼消息的寻呼无线网络临时标识。
S504、基站在与用户设备的覆盖范围等级对应的寻呼信道上向用户设备发送承载有寻呼消息的物理层帧。
本发明实施例中,基站在与用户设备的覆盖范围等级对应的寻呼信道上向用户设备发送承载有寻呼消息的物理层帧,以完成对用户设备的寻呼。
本发明实施例中,基站预先确定好用户设备的覆盖范围等级,且基站确定用户设备的覆盖范围等级的方式可以包括:
基站从用户设备发送的上行数据中获取用户设备的覆盖范围等级;或
基站检测用户设备在不同覆盖范围等级的上行信息的接入性能,并选取最大接入性能对应的覆盖范围等级作为用户设备的覆盖范围等级;或
基站将基站中存储的用户设备的覆盖范围等级确定为用户设备的覆盖范围等级;或
基站从核心网获取用户设备的覆盖范围等级,其中,核心网中存储有基站在用户设备由连接状态转为空闲状态时向核心网发送的用户设备的覆盖范围等级,或核心网中存储有用户设备在用户设备由连接状态转为空闲状态时向核心网发送的用户设备的覆盖范围等级。
本发明实施例中,当用户设备由连接状态转为空闲状态时,基站可以保留连接状态时的上下文,即基站能够根据保留的上下文获取到用户设备的覆盖范围等级,基站也可以只保留用户设备的用户设备标识以及对应的覆盖范围等级,基站还可以将用户设备的覆盖范围等级发送给核心网,以使核心网存储用户设备的覆盖范围等级,且基站可以通过与核心网中的移动管理实体(MME,Mobility Management Entity)之间的上行信令向核心网传递用户设备的覆盖范围等级。当基站需要向用户设备发送寻呼消息时,核心网中的MME向基站发送寻呼消息,基站从MME发送的寻呼消息中获取用户设备的覆盖范围等级,且核心网可以通过与基站之间的下行信令向基站发送包括用户设备的覆盖范围等级的寻呼消息。
可选的,核心网可以通过新定义的下行信令或信息要素(IE,Infromation Element)来传递用户设备的覆盖范围等级,且新定义的下行信令或信息要素包括在MME向基站发送的寻呼消息中。
举例来说,假设基站通过用户设备上下文释放完成(UE CONTEXT RELEASE COMPLETE)消息中新增的一个IE来指示用户设备的覆盖范围等级,则该用户设备上下文释放完成消息可以如下表1所示:
表1 用户设备上下文释放完成消息
Figure PCTCN2014088989-appb-000001
Figure PCTCN2014088989-appb-000002
其中,Coverage Class为用户设备上下文释放完成消息中新增的IE,且用于表示覆盖范围等级,XXXX表示与用户设备对应的具体的覆盖范围等级的值。
举例来说,假设MME在向基站下发的寻呼消息中增加一个IE来表示用户设备的覆盖范围等级,则MME向基站下发的寻呼消息可以如表2所示:
表2 MME向基站下发的一种寻呼消息
Figure PCTCN2014088989-appb-000003
Figure PCTCN2014088989-appb-000004
其中,Coverage Class为MME在向基站发送的寻呼消息中新增的IE,且用于表示覆盖范围等级,XXXX表示与用户设备对应的具体的覆盖范围等级的值。
举例来说,若MME重用现有的IE向基站发送指示用户设备的覆盖范围等级的寻呼消息,则MME向基站下发的寻呼消息可以如表3所示:
表3 MME向基站下发的另一种寻呼消息
Figure PCTCN2014088989-appb-000005
Figure PCTCN2014088989-appb-000006
其中,Paging Priority表示寻呼优先级,针对表3,MME对Paging Priority作了新的解释,即越高的寻呼优先级对应越小的覆盖范围等级,如最高寻呼优先级对应正常覆盖范围等级。
本发明实施例中,在M2M系统中,寻呼消息是在寻呼控制信道PCCH的逻辑信道上发送的,该PCCH的逻辑信道映射到寻呼信道PCH上,该PCH的传输信道映射到物理下行共享信道PDSCH的物理信道上,且逻辑信道、传输信道以及物理信道间的映射关系可以如图12所示,图12是本发明实施例公开的一种寻呼消息的信道映射关系示意图。
本发明实施例中,基站首先确定物理层帧中用户设备的寻呼消息的无线超帧标识,其中,无线超帧标识用于指示寻呼消息所处的无线超帧,然后,基站 以无线超帧标识为依据确定无线超帧中寻呼消息的第一位置标识,其中,第一位置标识用于指示寻呼消息在无线超帧中所处的目标位置且第一位置标识包括下行控制信息间隔标识或无线帧标识,并以第一位置标识为依据将寻呼消息承载在对应的目标位置中,最后,基站在与用户设备的覆盖范围等级对应的寻呼信道上向用户设备发送承载有寻呼消息的物理层帧,以完成对用户设备的寻呼。本发明实施例提供了一种针对新设置的物理层帧的寻呼方法,满足了基站对于下行业务的支持且降低了基站与用户设备的功耗。
