随着物联网的兴起,机器对机器(英文:Machine to Machine,M2M)通信应用越来越广泛,其中低功耗广域(英文:Low-Power Wide-Area,LPWA)M2M具有非常大的应用前景。由于LPWA M2M终端的位置固定不变,因此可以采用更长的周期性位置更新定时器来降低M2M终端周期位置更新的频度,以降低终端功耗,达到省电的目的。
在相关技术中,为了实现采用周期更长的周期性位置更新定时器,移动性管理实体(英文:Mobility Management Entity,MME)/服务GPRS支持节点(英文:Serving GPRS Support Node,SGSN)为用户设备(英文:User Equipment,UE)的周期性位置更新定时器配置预先设定的时长。
但是,采用上述配置固定的周期性位置更新定时器时长的方法,可能先向MME/SGSN发送位置更新请求,再向MME/SGSN发送应用层数据,由于MME/SGSN在接收到UE发送的应用层数据时,就可以得知UE处于连接状态,并不需要先根据UE发送的位置更新请求确定UE的连接状态,因此,不但增加了M2M终端的耗电,还浪费了空口资源,增加信令负荷。
发明内容
为了解决因在UE发送应用层数据给MME/SGSN的过程中不断的向MME/SGSN发送位置更新请求,增加了M2M终端的耗电和网络信令负荷的问题,本申请实施例提供了一种周期性位置更新定时器的设置方法、装置及网络设备。所述技术方案如下:

向所述UE发送确定出的所述周期性位置更新定时器的时长。
通过统计UE的应用层数据的发送周期,将UE的周期性位置更新定时器的时长设置为大于UE的应用层数据的发送周期长度;由于UE的周期性位置更新定时器的时长大于UE的应用层数据的发送周期长度,可以使得UE在发送应用层数据之后,不再进行周期位置更新,因此解决了相关技术中在UE发送应用层数据给MME/SGSN的过程中不断的向MME/SGSN发送位置更新请求,增加了M2M终端的耗电和网络信令负荷的问题;达到了可以减少M2M终端的耗电和网络信令负荷的效果。

通过计算相邻两次接收到UE发送的指定类型的NAS消息的时间间隔,获得UE的应用层数据的发送周期,由于指定类型用于指示传送应用层数据或者用于指示建立传输应用层数据的用户面连接,因此,相邻两个指定类型的NAS消息的时间间隔可以代表UE的的应用层数据的发送周期。
结合第一方面或者第一方面的第一种可能的实现,在第一方面的第二种可能的实现中,所述根据所述时间间隔,获得所述UE的应用层数据的发送周期,包括:
将得到的一个时间间隔作为所述UE的应用层数据的发送周期;或者,
将得到的至少两个时间间隔的平均值作为所述UE的应用层数据的发送周期。
通过计算相邻两次接收到UE发送的指定类型的NAS消息的时间间隔,根据至少两个时间间隔统计UE的应用层数据的发送周期,使得应用层数据的发送周期更为准确。
结合第一方面、第一方面的第一种可能的实现或者第一方面的第二种可能的实现,在第一方面的第三种可能的实现中,所述获取相邻两个指定类型的NAS消息之间的时间间隔,包括:
获取所述NAS消息的类型指示字段,所述类型指示字段用于指示NAS消息的类型;
若所述类型指示字段指示的NAS消息类型为所述指定类型,则记录接收到所述NAS消息的接收时刻;
根据记录的相邻的两个接收时刻,获得所述时间间隔。
结合第一方面、第一方面的第一种可能的实现至第一方面的第三种可能的实现中的任一种,在第一方面的第四种可能的实现中,所述根据所述应用层数据的发送周期,确定所述UE的周期性位置更新定时器的时长,包括:
将所述应用层数据的发送周期的时长除以所述周期性位置更新定时器的时长的单位得到的商值向下取整,并将所述向下取整的商值与偏移量之和作为所述周期性位置更新定时器的时长;或,
将所述应用层数据的发送周期的时长与偏移量之和作为所述UE的周期性位置更新定时器的时长。
结合第一方面、第一方面的第一种可能的实现至第一方面第四种可能的实现中的任一种,在第五种可能的实现中,在所述根据所述UE的应用层数据的发送周期,确定所述UE的周期性位置更新定时器的时长之后,所述方法还包括:
当所述周期性位置更新定时器的时长小于预定最小值时,将所述周期性位置更新定时器的时长更新为所述预定最小值;
当所述周期性位置更新定时器的时长大于预定最大值时,将所述周期性位置更新定时器的时长更新为所述预定最大值。
通过设置预定最小值或预定最大值,使得周期性位置更新定时器的时长可以满足一些特殊场景。
结合第一方面、第一方面的第一种可能的实现至第一方面的第五种可能的实现,在第六种可能的实现中,所述根据所述NAS消息,获取所述UE的应用层数据的发送周期之前,所述方法还包括:
获取所述UE的签约数据中的自动调整标志;
若所述自动调整标志用于指示所述UE的周期性位置更新定时器的时长被 允许自动调整,则执行所述根据所述NAS消息,获取所述UE的应用层数据的发送周期的步骤。
结合第一方面、第一方面的第一种可能的实现至第一方面的第六种可能的实现,在第七种可能的实现中,在所述接收UE发送的NAS消息之前,所述方法还包括:
接收所述UE发送的附着请求,根据本地配置或者从归宿位置寄存器(英文:Home Location Register,HLR)或归属签约用户服务器(英文:Home Subscriber Server,HSS)获得的签约数据,确定所述UE的周期性位置更新定时器的初始时长;

通过在为UE配置过周期性位置更新定时器的初始时长之后,若接收到UE发送的位置更新请求,则调整该UE的周期性位置更新定时器;由于在为UE配置过周期性位置更新定时器的初始时长之后,若接收到UE发送的位置更新请求,则表明配置的周期性位置更新定时器的初始时长小于应用层数据的发送周期长度,因此,还需要重新调整该UE的周期性位置更新定时器,以保证周期性位置更新定时器的时长大于应用层数据的发送周期长度。
结合第一方面的第九种可能的实现,在第十种可能的实现中,位置更新请求为跟踪区更新(英文:Tracking Area Update,TAU)请求或路由区更新(英 文:Routing Area Update,RAU)请求,所述位置更新应答为TAU应答或RAU应答。

附图说明
为了更清楚地说明本发明实施例中的技术方案,下面将对实施例描述中所需要使用的附图作简单地介绍,显而易见地,下面描述中的附图仅仅是本发明的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动的前提下,还可以根据这些附图获得其他的附图。

具体实施方式
为使本发明的目的、技术方案和优点更加清楚,下面将结合附图对本发明实施方式作进一步地详细描述。
在本文提及的“模块”是指存储在存储器中的能够实现某些功能的程序或指令;在本文中提及的“单元”是指按照逻辑划分的功能性结构,该“单元”可以由纯硬件实现,或者,软硬件的结合实现。
请参考图1,其示出了本发明一示例性实施例提供的网络侧设备的结构示意图。该网络侧设备包括:处理器11、网络接口12和存储器13。
处理器11包括一个或者一个以上处理核心,处理器11通过运行软件程序以及模块,从而执行各种功能应用以及数据处理。
网络接口12可以为多个,其中一些网络接口12用于和用户设备通信。另一些网络接口12用于与HLR或者HSS设备通信。
存储器13通过可以通过总线等连接方式与处理器11相连,存储器13可用于存储软件程序以及模块。
存储器13可以存储至少一个功能所需的应用程序模块14,应用程序模块14可以包括接收模块141、处理模块142、发送模块143,这些模块可以与处理器13、网络接口12以及其他硬件结合执行图2中的相应操作。比如,接收模块141可以作为接收机,其可以与网络接口12结合实现从其他设备接收数据的操作,还比如,发送模块143可以作为发送机,其可以与网络接口12结合实现向其他设备发送数据的操作。
存储器13可以由任何类型的易失性或非易失性存储设备或者它们的组合实现,如静态随机存取存储器(英文:static random access memory,SRAM),电可擦除可编程只读存储器(英文:electrically erasable programmable read-only memory,EEPROM),可擦除可编程只读存储器(英文:erasable programmable read only memory,EPROM),可编程只读存储器(英文:programmable read only memory,PROM),只读存储器(英文:read only memory image,ROM),磁存储器,快闪存储器,磁盘或光盘。
本领域技术人员可以理解,图1中所示出的网络侧设备的结构并不构成对网络设备的限定,可以包括比图示更多或更少的部件,或者组合某些部件,或者不同的部件布置。
下述实施例中以网络侧设备为MME或SGSN为例进行举例说明。
请参考图2,其示出了本发明一示例性实施例提供的周期性位置更新定时器的设置方法的流程图。本实施例以该方法用于如图1所示的网络侧设备110中来举例说明,由如图1所示的网络侧设备110的处理器21分别执行下述相应步骤,该方法包括以下几个步骤:
步骤201,接收与应用对应的配置参数。
该配置参数为在为应用调整周期性位置更新定时器的时长时需要的参数。这里的配置参数可以由维护人员预先配置。
配置参数可以包括为该应用调整周期性位置更新定时器的缺省时长、自动调整标志。周期性位置更新定时器用于对UE发送位置更新请求的周期进行定时。
可选的,配置参数还可以包括统计窗口。
可选的,配置参数还可以包括预定最小值和预定最大值中的至少一种。
由于LPWA M2M的终端通常具有唯一的业务应用,因此这里的自动调整标志用于指示可以对UE的周期性位置更新定时器的时长进行自动调整。
本实施例中可以以接入点名称(英文:Access Point Name,APN)或组标识(英文:GroupID)来标识应用。
本步骤可以通过图1中存储器13中的接收模块141来实现。
步骤202,接收UE发送的附着请求。
在附着请求(英文:Attach Request)中,通常会包含应用的标识,以及用于指示UE是否支持延长周期性位置更新定时器的指示标记。
举例来讲,当Attach Request消息中MS network feature support信元的extended periodic timer的bit位被设置为1时,可以表明支持延长周期性位置更新定时器。
本步骤可以通过图1中存储器13中的接收模块141来实现。
步骤203,获取签约数据。
网络设备(比如MME或SGSN)可以从HLR/HSS获取签约数据,该签约数据一般包含签约好的周期性位置更新定时器,比如Subscribed-Periodic-RAU-TAU-Timer,UE所属的组标识。
本步骤可以通过图1中存储器13中的接收模块141来实现。
步骤204,根据本地配置或签约数据,确定周期性位置更新定时器的初始时长。
网络设备根据本地配置或签约数据,确定周期性位置更新定时器的初始时长时,可以通过如下步骤:
1)若签约数据未包含签约好的周期性位置更新定时器,但本地配置中应用对应的APN配置了周期性位置更新定时器,则将本地配置中配置的该周期性位置更新定时器所对应的时长确定为初始时长。
本地配置中配置的该周期性位置更新定时器所对应的时长即为配置参数中周期性位置更新定时器的缺省时长。
2)若签约数据包含签约好的周期性位置更新定时器,则将签约的周期性位置更新定时器所对应的时长确定为初始时长。
本步骤可以通过图1中存储器13中的处理模块142来实现。
步骤205,向UE发送附着应答,该附着应答中携带周期性位置更新定时器的初始时长。
网络设备将周期性位置更新定时器的初始时长添加至附着应答(英文:Attach Accept),将该附着应答发送至UE。
这样,UE则可以根据该初始时长设置周期性位置更新定时器的周期,并根据该周期性位置更新定时器的周期进行周期位置更新。
本步骤可以通过图1中存储器13中的发送模块143来实现。
步骤206,接收UE发送的NAS消息。
UE向网络设备发送服务请求(英文:Service Request)消息建立传输移动台发起(英文:Mobile Originated,MO)数据(也即下行数据)的用户面连接,或者发送NAS消息传输MO数据,对应的,网络设备可以接收到UE发送的NAS消息。
本步骤可以通过图1中存储器13中的接收模块141来实现。
步骤207,获取UE的签约数据中的自动调整标志,在自动调整标志用于指示UE的周期性位置更新定时器的时长被允许自动调整时,根据NAS消息,获取UE的应用层数据的发送周期。
当配置参数中的自动调整标志用于指示UE的周期性位置更新定时器的时长被允许自动调整时,网络设备则根据NAS消息统计UE的应用层数据的发送周期。
网络设备从UE接收到的NAS消息有较多的类型,而其中用于传输应用层数据的NAS消息和用于建立传输应用层数据的用户面连接的NAS消息与UE的应用层数据的发送周期相关,因此可以利用这两类NAS消息来获取UE的应用层数据的发送周期,本实施例中将这两类NAS消息定义为指定类型的NAS消息。
对于M2M类型的UE来讲,通常仅有一个应用,因此UE发送的指定类型的NAS消息中仅存在一种应用的应用层数据的发送。
网络设备根据该指定类型的NAS消息统计该UE的应用层数据的发送周期时,可以包括:
第一,获取相邻两个指定类型的NAS消息之间的时间间隔,指定类型的NAS消息包括以下至少一种:包括传输应用层数据的NAS消息和包括用于建立传输应用层数据的用户面连接的数据的NAS消息。
网络设备在接收到NAS消息后,获取NAS消息的类型指示字段,该类型指示字段用于指示NAS消息的类型;若类型指示字段指示的NAS消息类型为指定类型,则可以判定该NAS消息为指定类型的NAS消息,此时则记录接收到NAS消息的接收时刻;利用记录的相邻的两个接收时刻,获得时间间隔。
在利用记录的相邻的两个接收时刻,获得时间间隔时的方式比较多,比如可以将相邻的两个接收时刻中最后接收时刻减去在前接收时刻,得到时间间隔;还比如,将相邻的两个接收时刻的差值取绝对值,得到时间间隔。
需要说明的是,网络设备获取类型指示字段并根据类型指示字段判定是否为指定类型的时长非常短,相对于从UE接收两个相邻的指定类型的NAS之间的时间间隔来讲,可以忽略不计。
可选的,在实际实现时,为了使得计算得到的时间间隔更为精准,网络设备在每接收到一个NAS消息时均记录接收时刻,并在判定NAS消息不为指定类型的NAS消息时,删除其对应的接收时刻,这样则仅保留了指定类型的NAS消息的接收时刻。
上述的类型指示字段在实现时,可以在NAS消息定义一个用于指示NAS消息类型的字段,NAS消息的类型不同时,该类型指示字段的取值也不同。可选的,该类型指示字段可以位于NAS消息的报文头中。
可选的,还可以根据NAS消息中某些已有字段(比如Generic message container type)的取值来确定NAS消息的类型。比如在NAS消息中Generic message container type的取值为Uplink generic NAS transport或Downlink generic NAS transport时,表明UE在上行传输应用层数据或下行传输应用层数据,此时网络设备则可以认定该NAS消息为用于传输应用层数据的NAS消息,即为指定类型的NAS消息。
显然,还可以通过其他方式来限定类型指示字段所指示的指定类型,本实施例中对此不作限定。
第二,根据时间间隔,获得UE的应用层数据的发送周期。
可选的,可以将获得的一个时间间隔作为UE的应用层数据的发送周期;或者,将获取的至少两个时间间隔的平均值作为UE的应用层数据的发送周期。
这里选取的时间间隔的个数可以由步骤201设置的配置参数中的统计窗口来决定。
举例来讲,当统计窗口为3时,可以获取连续三次接收到的指定类型的NAS消息,计算第一次接收到指定类型的NAS消息和第二次接收到指定类型的NAS消息之间的时间间隔,以及计算第二次接收到指定类型的NAS消息和第三次接收到指定类型的NAS消息之间的时间间隔,求取这两个时间间隔的平均值,将得到的平均值确定为该UE的应用层数据的发送周期。
在实际实现时,配置参数中的统计窗口过大时,需要等待较长的时间才能计算出应用层数据的发送周期,从而导致UE会进行多次周期位置更新。因此,为了能够尽可能的减少UE侧进行周期位置更新的次数,这里统计窗口可以设置为3,也即意味着连续接收三次指定类型的NAS消息即进行应用层数据的发送周期的统计。由于统计窗口为3时,可以统计两个时间间隔的平均值,使得统计出的应用层数据的发送周期较为精准。
本步骤可以通过图1中存储器13中的处理模块142来实现。
步骤208,根据应用层数据的发送周期,确定UE的周期性位置更新定时器的时长,该周期性位置更新定时器的时长大于该应用层数据的发送周期长度。
由于若UE发送了应用层数据或者建立了用于传输应用层数据的用户面连接,MME或SGSN则会认定该UE在服务范围内,此时UE没有必要再向MME或SGSN发送位置更新(比如TAU/RAU)请求。因此,这里可以将设置的该周期性位置更新定时器的时长大于该应用层数据的发送周期长度,以减少周期位置更新。
网络设备在根据该应用层数据的发送周期设置该UE的周期性位置更新定时器的时长时的实现方式可以至少包括如下两种方式:
第一种方式,将应用层数据的发送周期的时长除以周期性位置更新定时器的时长的单位得到的商值向下取整,并将向下取整的商值与偏移量之和作为周期性位置更新定时器的时长。
这里所讲的偏移量为大于0的值,比如可以为1、2等,本实施例不对偏移量的取值进行限定。
这里所讲的周期性位置更新定时器的时长的单位可以为预先设置的可选单位中最合适单位。也即,周期性位置更新定时器的时长的单位可以使得得到的周期性位置更新定时器的时长位于预定的取值范围内。
一般来讲,周期性位置更新定时器包括取值和单位,取值范围一般为[0,31],可选的单位则可以包括10分钟、1小时、10小时、2秒、30秒、1分钟等。
以偏移量取值为1为例,当应用层数据的发送周期为12小时时,若将应用层数据的发送周期12小时除以10分钟,则得到的商值向下取整后为72,加1后为73,取值73并不在取值范围[0,31]内,因此选取的单位10分钟并不是合适的单位。
这里可以将周期性位置更新定时器的时长的单位取为1小时,当应用层数据的发送周期为12小时时,若将应用层数据的发送周期12小时除以1小时,则得到的商值向下取整后为12,加1后为13,取值13位于取值范围[0,31]内。
需要说明的是,这里将得到的商值向下取整后加偏移量的目的是:保证周期性位置更新定时器的时长大于应用层数据的发送周期的时长。
第二种方式,将应用层数据的发送周期的时长与偏移量之和作为UE的周期性位置更新定时器的时长。
本步骤可以通过图1中存储器13中的处理模块142来实现。
网络设备在确定出UE的周期性位置更新定时器的时长后,则可以向UE发送确定出的周期性位置更新定时器的时长。在一种实现中,可以结合步骤209和步骤210将周期性位置更新定时器的时长发送给UE。
步骤209,接收UE发送的位置更新请求。
本步骤可以通过图1中存储器13中的接收模块141来实现。
步骤210,向UE发送位置更新应答,位置更新应答中携带有设置的周期性位置更新定时器的时长。
在网络设备计算好周期性位置更新定时器的时长后,若再次接收到UE发送的位置更新请求,表明步骤204中设置的周期性位置更新定时器的时长小于应用层数据的发送周期长度,因此,可以向UE发送位置更新应答,该位置更新应答中携带有步骤208设置的周期性位置更新定时器的时长,以使得UE侧的周期性位置更新定时器的时长大于应用层数据的发送周期的时长。
请对比图3A和图3B,图3A中应用层数据的发送周期长度大于位置更新周期的时长,当UE重启周期性位置更新定时器时,由于周期性位置更新定时器的时长小于应用层数据的发送周期长度,因此在UE发送应用层数据的发送之前,先进行周期位置更新,然后等待UE发送应用层数据的发送。也即UE需要不断的进行周期位置更新,增加了终端的耗电和网络信令负荷。
图3B中应用层数据的发送周期长度小于位置更新周期的时长,当UE重启周期性位置更新定时器时,由于周期性位置更新定时器的时长大于应用层数据的发送周期长度,因此UE先发送应用层数据,且在发送应用层数据之后会重新启动周期位置更新,然后等待UE再次发送应用层数据。也即UE仅进行应用层数据的发送,完全取消了周期位置更新的过程,节省了终端的耗电、降低了对网络的信令负荷。图3B中的虚线表示原本在位置更新的时机不再进行位置更新。
本步骤可以通过图1中存储器13中的处理模块142来实现。
需要补充说明的是,在一些场景中,UE接收移动台终止(英文:Mobile Terminated,MT)数据(也即上行数据)的时延会受到限定,此时,若UE发送应用层数据的周期过大,且由于周期性位置更新定时器的周期大于应用层数据的发送的周期,因此UE不会进行周期位置更新,此时为了能够可以向UE发送MT数据,可以将周期性位置更新定时器的时长更新为向UE发送MT数据的时延。也即在步骤208之后,当设置的该周期性位置更新定时器的时长大于预定最大值时,将该周期性位置更新定时器的时长更新为该预定最大值,这里的预定最大值即为发送MT数据的时延。
在另一些场景中,若UE停止了应用层的应用层数据的发送,此时UE则会根据周期性位置更新定时器进行周期位置更新,而如果长时间段内并没有数据需要发送,频繁进行周期位置更新会消耗UE的电量,此时则可以将周期性位置更新定时器的时长更新为预定最小值。也即在步骤208之后,当设置的该周期性位置更新定时器的时长小于预定最小值,将该周期性位置更新定时器的时长更新为该预定最小值。
综上所述,本发明实施例提供的周期性位置更新定时器的设置方法,通过统计UE的应用层数据的发送周期,将UE的周期性位置更新定时器的时长配置为大于UE的应用层数据的发送周期长度;由于UE的周期性位置更新定时器的时长大于UE的应用层数据的发送周期长度,可以使得UE在发送应用层 数据之后,不再进行周期位置更新,因此解决了相关技术中因在UE发送应用层数据给MME/SGSN的过程中不断的向MME/SGSN发送位置更新请求,增加了M2M终端的耗电和网络信令负荷的问题;达到了可以减少M2M终端的耗电和网络信令负荷的效果。
通过计算相邻两次接收到UE发送的指定类型的NAS消息的时间间隔,获得UE的应用层数据的发送周期,由于指定类型用于指示传送应用层数据或者用于指示建立传输应用层数据的用户面连接,因此,相邻两个指定类型的NAS消息的时间间隔可以代表UE的的应用层数据的发送周期。
通过计算相邻两次接收到UE发送的指定类型的NAS消息的时间间隔,根据至少两个时间间隔统计UE的应用层数据的发送周期,使得应用层数据的发送周期更为准确。
通过在为UE配置过周期性位置更新定时器的初始时长之后,若接收到UE发送的位置更新请求,则调整该UE的周期性位置更新定时器;由于在为UE配置过周期性位置更新定时器的初始时长之后,若接收到UE发送的位置更新请求,则表明配置的周期性位置更新定时器的初始时长小于应用层数据的发送周期长度,因此,还需要重新调整该UE的周期性位置更新定时器,以保证周期性位置更新定时器的时长大于应用层数据的发送周期长度。
需要说明的是,在实际实现时,还可以仅包括上述步骤的部分步骤,比如由步骤206至步骤210得到一种实施例,还比如,由步骤201、步骤206至步骤210得到另一种实施例。上述实施例中的步骤组合并不能用于限定本发明。
请参考图4,其示出了本发明一个实施例提供的周期性位置更新定时器的设置装置的框图。该周期性位置更新定时器的设置装置可以通过软件、硬件或者两者的结合实现成为检测设备的全部或者一部分。该周期性位置更新定时器的设置装置可以包括:接收单元410、处理单元420和发送单元430。
接收单元410,用于实现上述步骤201、202、203、206、209功能。
处理单元420,用于实现上述步骤204、207、208功能。
发送单元430,用于实现上述步骤205、210功能。
