Abstract
本发明实施例提供一种寻呼方法、网络设备及系统,涉及通信领域,实现在不能独立部署的新的无线接入技术基站依赖于成熟的无线接入技术网络核心网的场景中,由新的无线接入技术基站对UE进行寻呼时,在适应网络需求的同时,保证UE续航能力。本发明提供的方案包括:接收MME发送的第一寻呼消息;若确定需要在第二无线接入技术网络中对所述UE进行寻呼,向提供所述第二无线接入技术网络的至少一个第二基站发送第二寻呼消息,所述第二寻呼消息携带寻呼周期信息,所述第二寻呼消息指示所述至少一个第二基站对所述UE进行寻呼。本发明用于寻呼。
Description
本发明涉及通信领域,尤其涉及一种寻呼方法、网络设备及系统。
在长期演进(Long Term Evolution,简称LTE)系统中,当空闲态的用户设备(User Equipment,简称UE)有下行数据到达,移动管理实体(Mobility Management Entity,简称MME)将通知演进型基站(evolved Node B,简称eNB)进行寻呼,由eNB在周期性的寻呼时刻向UE发送寻呼消息,UE接收到寻呼消息后将发起服务请求,响应核心网的寻呼消息。
现有LTE网络中,寻呼周期以无线帧为单元,包括默认的寻呼周期和UE特定的寻呼周期。如果UE配置了特定的寻呼周期(寻呼非连续接收周期),eNB会选择默认的寻呼周期和UE特定的寻呼周期中较小的作为UE的寻呼周期。
随着技术的发展,新的无线接入技术(Radio Access Technology,简称RAT)日益涌现,随着高频频段无线资源的引入,在新的无线接入技术网络中帧长相比于现在LTE网络的帧长将变得更短。为了新的无线接入技术的快速部署,一种可行的方案是在初期只部署新的无线接入技术基站用于提供新的空口服务,而不部署新的无线接入技术核心网,新的无线接入技术基站可以依赖于现有LTE系统运行。示例性的,针对新的无线接入技术基站,可能的部署场景包括但不限定于如图1和图2所示。
在新的无线接入技术基站依赖于LTE核心网的场景中,当LTE核心网通过新的无线接入技术基站对UE进行寻呼时,如果沿用LTE的寻呼周期,由于新的无线接入技术中的帧长比LTE帧长短,将会导致UE频繁唤醒以监听寻呼,这会降低UE的续航能力。比如,LTE
网络中确定UE的寻呼周期为32个无线帧,在LTE中,如图3所示,32个无线帧为320毫秒(millisecond,简称ms),而在新的无线接入技术网络中帧长将变短,以1ms帧长为例,此时32个无线帧为32ms,若沿用LTE网络中UE的寻呼周期,即32个无线帧,UE每32ms就需要唤醒一次。
因此,在不能独立部署的新的无线接入技术基站依赖于成熟的无线接入技术网络核心网的场景中,由新的无线接入技术基站对UE进行寻呼时,没有合适的寻呼周期在适应网络需求的同时,保证UE续航能力。

第四方面,提供又一种寻呼方法,应用于MME,所述MME为
第一无线接入技术网络的核心网设备;所述方法包括:
接收UE发送的所述UE在所述第一无线接入技术网络中的第一寻呼非连续接收周期,及所述UE在第二无线接入技术网络中的第二寻呼非连续接收周期;其中,所述提供第二无线接入技术网络的第二基站依赖所述第一无线接入技术网络的核心网运行;
向提供所述第一无线接入技术网络的至少一个第一基站发送第一寻呼消息;或者,若确定需要在所述第二无线接入技术网络中对所述UE进行寻呼,向至少一个所述第二基站发送携带所述第二寻呼非连续接收周期的第二寻呼消息;其中,所述第一寻呼消息包括所述第一寻呼非连续接收周期和/或所述第二寻呼非连续接收周期。
其中,所述UE可以通过第一基站或第二基站接入所述MME所在的核心网。
因此,UE在向MME上报寻呼非连续接收周期时,需上报所述UE在每一个无线接入技术网络中的寻呼非连续接收周期,以便于MME将寻呼非连续接收周期发送给对应基站,使得基站合理确定UE在其提供的无线接入技术网络中的寻呼周期,进而对UE进行合理寻呼,以实现在满足网络需求的情况下,保证UE的续航能力。
可选的,当MME收到UE发送的所述UE在所述第一无线接入技术网络中的第一寻呼非连续接收周期,及所述UE在第二无线接入技术网络中的第二寻呼非连续接收周期时,可以直接将所述UE在所述第一无线接入技术网络中的第一寻呼非连续接收周期,及所述UE在第二无线接入技术网络中的第二寻呼非连续接收周期携带于寻呼消息中,发送给至少一个第一基站,由第一基站确定对UE进行寻呼的无线接入技术网络。

可选的,由于MME是第一无线接入技术网络的核心网设备,因此MME与第一基站间存在接口;而第二基站依赖第一无线接入
技术网络的核心网运行,在配置时,MME与第二基站直接可以有接口,也可以没有接口。
这样一来,MME向第二基站发送寻呼消息时,根据两者之间是否存在接口,可以通过第一基站转发,也可以直接发送,本发明对此不进行具体限定。

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,所描述的实施例仅仅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。
在目前的LTE系统中,当空闲态的UE有下行数据到达,MME将通知eNB对该UE进行寻呼,UE接收到寻呼消息后将发起服务请求,响应核心网的寻呼消息。
具体的,eNB在周期性的寻呼时刻(Paging Occasion,简称PO)发送对应UE的寻呼消息,包含PO的无线帧称为寻呼帧(Paging Frame,简称PF)。寻呼周期包括两种,一种是eNB配置的默认的寻呼周期(defaultPagingCycle),另一种是UE特定的寻呼周期;如果UE配置了特定的寻呼周期,eNB会选择两种中较小的作为eNB对UE进行寻呼的寻呼周期。
在空闲状态下,UE在一个寻呼周期内被分配了唯一的寻呼时刻,因此为了减少电池消耗,可以采用非连续接收,则对于每一个UE来说,寻呼周期可以称为寻呼非连续接收周期。
在eNB对UE进行寻呼之前,两者需要对寻呼周期保持一致,具体过程可以包括:
UE自身配置寻呼非连续接收周期,并在附着(attach)过程中通过非接入层(Non-Access Stratum,简称NAS)消息将寻呼非连续接收周期发送到MME。
MME对UE进行寻呼时向相应的eNB发送寻呼消息,在所述寻呼消息中携带UE的寻呼非连续接收周期。这样eNB就获得了UE的寻呼非连续接收周期,对比默认的寻呼周期和UE的寻呼非连续接收周期,从两者中选择较小的作为寻呼周期。
eNB在广播消息中将默认的寻呼周期发送给UE,UE对比默认
的寻呼周期和UE的寻呼非连续接收周期,从两者中选择较小的作为寻呼周期。
这样eNB和UE的寻呼周期就保持一致了。
进一步的,现有LTE系统中,不管是默认寻呼周期还是UE的寻呼非连续接收周期,都是以无线帧为单位的。
在广播的SIB2中,除了defaultPagingCycle,还有一个参数为nB是用于确定寻呼时刻(PO)的。要确定PO,除了nB之外,还需要MME向eNB发送的寻呼消息中携带的UE标识检索值(UE Identity Index value)和UE寻呼标识(UE Paging Identity)。
本发明的基本原理是:在第二基站依赖第一基站提供的第一无线接入技术网络的核心网的场景中,若确定需要在第二基站提供的第二无线接入技术网络中对UE进行寻呼,第一基站参考MME向其发送的第一寻呼消息,向第二基站发送携带寻呼周期信息的第二寻呼消息,以指示第二基站对UE进行寻呼。其中,通过寻呼周期信息的内容,控制第二基站对UE进行寻呼时的寻呼周期,以实现在满足网络需求的前提下,保证UE的续航能力,避免寻呼时的频繁唤醒。
