背景技术
移动网络中需要对终端设备执行移动管理,移动管理操作包括终端的位置注册和去注册、终端移动时终端位置的更新、终端定期执行位置更新等。移动管理的目的是让移动网络特别是核心网在终端附着到移动通信网络后,可以跟踪终端的位置,从而在需要发起和终端的有关业务时,可以通过终端所在的网络区域执行寻呼等操作,使得终端可以接入到网络并执行有关网络业务,例如分组数据的接收。
目前,3G和4G移动网络的移动管理机制比较单一,核心网设备对每个终端所采用的移动管理策略相同,即终端在变更网络区域时执行位置更新或者终端按照设定的定时器执行位置更新。未来,5G移动网络支持的业务场景包括移动宽带接入、低功耗的物联网设备的接入、需要低时延通信的工业控制设备的接入,同时终端可以采用WLAN(Wireless Local Area Networks,无线局域网)或者固网等非移动通信网络的接入方式接入到5G移动网络。由于5G移动网络中支持多种类型的终端的网络接入,而这些终端接入有不同的特征需求,比如低功耗的物联网终端一般在固定区域内使用,终端需要尽可能的减少功耗,因此当前的移动管理机制已经无法满足现有的管理需求,为此,需要提供一种新的移动管理机制,对不同终端进行差异化的移动管理。

具体实施方式
本申请实施例中,术语“终端”包括但不限于移动站、固定或移动用户单元、寻呼机、蜂窝电话、个人数字助理(Personal Digital Assistant,简称PDA)、计算机或任何其它类型的能在无线环境中工作的用户设备(user equipment)。术语“接入网设备”包括但不限于基站、节点、基站控制器、接入点(Access Point,简称AP)、远端节点(Remote Unit,RU)或任何其它类型的能够在无线环境中工作的接口设备。
本申请实施例中,网络区域可以是指小区(cell),也可以是指多个小区形成的联合区域,也可以是指预先设置的指定区域,本申请实施例对此并不限定。
本申请实施例中,核心网设备可以是指移动性管理实体(Mobility Management Entity,MME)或者移动性管理网络功能(Mobility Management Network Function,MM NF)等。
本申请实施例适用于4G(第四代移动通信系统)演进系统,如LTE(Long Term Evolution,长期演进)系统;5G(第五代移动通信系统)系统;CRAN(Cloud Radio Access Network,云无线接入网)等通信网络。举例来说,如图1所示,为可以应用本申请实施例的一种通信网络架构示意图。图1所示的网络络架构中包括终端、接入网设备、核心网设备等,其中接入网设备位于接入网,核心网设备位于核心网,终端通过接入网设备接入核心网,从而实现相关业务。核心网中还可以包括签约用户数据网络功能(subscriber data Network Function)和策略网络功能(Policy Network Function)等网络功能。
签约用户数据网络功能包含签约用户的业务签约信息,向核心网设备提供用户的签约信息,从而使核心网设备执行终端的身份验证和授权。策略网络功能用于获取终端的位置信息,并根据终端的位置信息生成终端的移动特征信息,例如策略网络功能可以包括用户感知(User awareness)网络功能等功能。当然也可以由其它设备生成终端的移动特征信息后提供给策略网络功 能。例如,由User awareness网络功能(独立的网元)获取用户的位置信息并生成用户的移动特征信息,然后由User awareness网络功能将移动特征信息提供给策略网络功能。这种情况下,策略网络功能保存有用户的移动特征信息,可以不再生成用户的移动特征信息。
基于上述论述,如图2所示,本申请实施例提供的一种移动管理方法流程示意图。
如图2所示,该方法可以包括以下步骤:
步骤201:终端向核心网设备发送网络区域标识;所述网络区域标识为所述终端将要驻留或接入的网络区域的标识。
步骤202:核心网设备获取终端的网络区域标识以及移动特征信息;所述网络区域标识为所述终端将要驻留或接入的网络区域的标识;所述移动特性信息包括所述终端的至少一个常驻留区域标识以及与至少一个常驻留区域标识对应的第一策略。
需要说明的是,本申请实施例中,常驻留区域可以是指终端的驻留时长超过第一阈值的区域或者终端的驻留次数超过第二阈值的区域。
步骤203:所述核心网设备根据所述终端的网络区域标识以及移动特征信息确定所述终端的移动管理策略;所述核心网设备向所述终端指示所述移动管理策略。
步骤204:所述终端接收核心网设备指示的移动管理策略,并根据所述移动管理策略在所述移动管理策略指示的网络区域中进行位置更新。
其中,所述移动管理策略为所述核心网设备根据终端的网络区域标识以及移动特征信息确定的。
步骤201中,终端可以通过包括所述网络区域标识的第一请求消息向核心网设备发送网络区域标识。所述第一请求消息可以用于请求接入核心网或者用于对所述终端的位置进行更新。第一请求消息还可以为终端接入网络后,向核心网设备发送的附着请求消息,用于请求接入核心网。在该场景下,终端已经与接入网设备建立了连接。当然,第一消息还可以为专门发送网络区 域标识的消息,本申请实施例对此并不限定。
可选的,核心网设备接收到第一请求消息之后,需要执行对终端的鉴权过程,从而验证终端的身份是否真实,并确定终端接入网络后使用的加密密钥等信息。
第一请求消息还可以为终端从一个网络区域移动到另一个网络区域时,向核心网设备发送的位置更新请求消息,用于对所述终端的位置进行更新。
终端发送的第一请求消息中可以包括终端将要驻留或接入的网络区域的标识、终端标识、终端的位置信息等信息中的一种或多种,本申请实施例对此并不限定。
进一步的,终端发送的第一请求消息中还可以包括移动策略支持信息,所述移动策略支持信息指示出终端支持的移动管理策略。例如终端支持第一移动策略和第二移动策略,则所述第一请求信息中包括指示终端支持第一移动策略和第二移动策略的移动策略支持信息。
步骤202中,核心网设备获取网络区域标识的方法有多种,一种可能的实现方式中,核心网设备接收终端发送的包括网络区域标识的第一请求消息,从而可以根据第一请求消息确定网络区域标识等信息。
一种可能的实现方式中,核心网设备接收终端发送的包括终端的位置信息的第一请求消息,从而可以根据终端的位置信息确定网络区域标识。终端的位置信息可以是指终端的经纬度坐标等信息。
核心网设备接收到第一请求消息之后,可以向策略网络功能发送用于请求所述终端的移动特征信息的第二请求消息,并接收所述策略网络功能发送的移动特征信息。当然,核心网设备也可以在收到第一请求消息之前通过策略网络功能获取终端的移动特征信息。其中,第二请求消息中可以包括终端的终端标识等信息。
需要说明的是,本申请实施例中,可以通过以下方式确定终端的移动特征信息:
步骤一,接入网设备和核心网设备可以将终端的移动事件发送给策略网 络功能。例如,核心网设备可以周期性的将获得到的终端的移动事件发送给策略网络功能。
其中,所述移动事件可以包括以下至少一项:
终端标识;
网络区域标识;
终端在所述网络区域标识所指示的网络区域驻留的时长;
终端在所述网络区域标识所指示的网络区域驻留的起始时刻;
终端在所述网络区域标识所指示的网络区域驻留的结束时刻。
步骤二,策略网络功能根据终端的移动事件确定终端的常驻留区域。终端的常驻留区域可以是指终端的驻留时长超过第一阈值的区域或者终端的驻留次数超过第二阈值的区域。第一阈值以及第二阈值可以根据实际情况确定,在此不再赘述。
可选的,策略网络功能还可以根据移动事件确定每个网络区域对应的驻留时间段,一个网络区域对应的驻留时间段为终端在所述驻留时间段内驻留在该网络区域内的次数大于预设阈值的时间段。例如,终端在8点至10点之间驻留在A区域中的次数大于预设阈值,则策略网络功能可以将A区域对应的驻留时间段确定为8点至10点。需要说明的是,每个网络区域可以对应至少一个驻留时间段。
步骤三,策略网络功能从终端的常驻留区域中选择至少一个网络区域,并将选择的至少一个网络区域的网络区域标识作为终端的至少一个常驻留区域标识,并将第一策略作为所述至少一个常驻留区域标识对应的策略,从而获得终端的移动特征信息。
结合前面的描述,可选的,策略网络功能还可以将每个网络区域对应的驻留时间段作为移动特征信息的一部分,此时,移动特征信息所包括的至少一个常驻留区域标识中的常驻留区域标识对应至少一个驻留时间段,具体的,所述至少一个常驻留区域标识中的部分或全部常驻留区域标识对应至少一个驻留时间段。
步骤203中,移动管理策略可以有多种,具体可以如表1所示。
表1
Figure PCTCN2016101709-appb-000001
Figure PCTCN2016101709-appb-000002
当然,以上只是示例,移动管理策略还可以有其他形式,在此不再逐一举例说明。
结合表1,如果核心网设备确定所示移动特征信息中存在与所述网络区域标识相同的常驻留区域标识,所述核心网设备则将与所述至少一个常驻留区域标识对应的第一策略确定为所述移动管理策略;相应的,如果核心网设备确定所示移动特征信息中不存在与所述网络区域标识相同的常驻留区域标识,所述核心网设备则将第二策略确定为所述移动管理策略。
当核心网设备则将与所述至少一个常驻留区域标识对应的第一策略确定为所述移动管理策略时,对在常驻留区域的终端可以由接入网进行移动管理,减少了核心网对终端进行移动管理的负荷,并且终端接收和发送数据时不需要在终端和核心网之间重新执行恢复网络连接的业务过程,节省了数据接收和发送的时延,同时减少了终端和核心网的信令负荷,另外可以减少了终端因收发数据而导致的电量消耗。
可选的,移动特征信息所包括的至少一个常驻留区域标识中的每个常驻留区域标识对应至少一个驻留时间段时,核心网设备将第一策略确定为所述移动管理策略之前,还需要确定获取终端的网络区域标识的时刻是否位于所述网络区域标识对应的驻留时间段内,以下将“核心网设备获取终端的网络区域标识的时刻”简称为“目标时刻”。具体的,所述核心网设备若确定目标时刻位于目标时间段中,则确定获取终端的网络区域标识的时刻位于所述网络区域标识对应的驻留时间段内;否则确定获取终端的网络区域标识的时刻不位于所述网络区域标识对应的驻留时间段内。其中,所述目标时间段为与所述网络区域标识相同的常驻留区域标识所对应的至少一个驻留时间段中的任意一个时间段。例如,A区域对应的驻留时间段确定为8点至10点,当核心网设备获取终端的网络区域标识的时刻为7点,则即使A区域的网络区域标识位于移动特征信息中,核心网设备也不会将终端在A区域中的移动管理策略确定为第一策略;当核心网设备为终端确定移动管理策略的时刻为9点,且在A区域的网络区域标识位于移动特征信息中时,核心网设备将终端在A区域中的移动管理策略确定为第一策略。
可选的,本申请实施例中,如果核心网设备确定所示移动特征信息中不存在与所述网络区域标识相同的常驻留区域标识,所述核心网设备则将第二策略确定为所述移动管理策略。
核心网设备为终端确定了移动管理策略之后,向终端指示所述移动管理策略,同时,核心网设备还可以向与所述终端建立连接的接入网设备指示所述移动管理策略,以便终端以及接入网设备根据所述移动管理策略执行移动 管理。
具体的,核心网设备可以通过发送移动管理策略的策略标识,向终端或者接入网设备指示出为所述终端确定的移动管理策略。当然,核心网设备还可以直接将移动管理策略发送给终端或者接入网设备。
需要说明的是,核心网设备向终端指示出为所述终端确定的移动管理策略的同时,还可以将移动管理策略对应的网络区域指示给终端。相应的,核心网设备还可以将移动管理策略对应的网络区域指示给接入网设备。
相应的,在步骤204中,终端根据确定出的移动管理策略进行位置更新。
举例来说,如图3所示,为本申请实施例提供的一种移动管理流程示意图。图3所示的流程中,移动管理策略为第一策略,在第一策略中,核心网设备保持所述核心网设备与终端的连接为连接状态。
步骤301:终端确定终端的位置信息。
步骤302:终端向接入网设备发送所述位置信息。
终端可以周期性的向接入网设备上报所述终端的位置信息;终端还可以在确定终端的位置发生变化时,向接入网设备上报所述终端的位置信息。
终端发送的位置信息可以是该比网络区域粒度更小的信息,比如是该终端的所在的网络小区标识的信息。具体的,终端可以向接入网设备发送单独的无线资源控制(Radio Resource Control,RRC)位置更新信令,例如RRC_AreaUpdate,在该RRC位置更新信令中包括终端的标识、终端所在的网络小区标识,例如Cell ID,从而使接入网设备可以得到终端的位置信息;进一步的接入网设备接收到RRC位置更新信令后,可以向终端发送位置更新响应消息,例如RRC_AreaUpdate_Response。
步骤303:接入网设备更新终端的位置信息。
步骤304:接入网设备向终端回复确认消息,用于确认接收到终端发送的位置信息。
上述方法中,由于终端的位置更新流程不需要核心网设备的参与,减少了位置更新所需要的网络信令的数量,并避免对核心网造成信令负荷。
再举例来说,如图4所示,为本申请实施例提供的一种移动管理流程示意图。图4所示的流程中,移动管理策略为第一策略,在第一策略中,接入网设备确定终端未发送数据时,将所述接入网设备和终端的连接态设置为空闲状态;终端和接入网的连接态设置为空闲状态时,接入网设备保留终端的上下文信息。具体的,接入网设备和核心网设备之间存在为该终端建立的控制面连接和用户面连接。接入网设备保存为该终端建立的控制面连接和用户面连接的上下文信息,包括连接的标识、连接的状态(空闲状态或处于连接状态),处理该连接的核心网设备的标识或地址信息,连接的配置信息等。核心网设备保存为该终端建立的控制面连接和用户面连接的上下文信息,包括连接的标识、连接的状态(空闲状态或处于连接状态),处理该连接的接入网设备的标识或地址信息,连接的配置信息等。
步骤401:核心网设备接收应用服务器向终端发送的下行数据后,直接将下行数据转发给接入网设备。具体的,服务于该终端的用户面连接的核心网设备根据终端用户面连接的配置信息确定所述用户面连接所对应的接入网设备的设备或标识,并将所述下行数据发送给所述接入网设备。
步骤402:接入网设备在终端所处的网络区域内向终端发送寻呼消息,用于寻呼终端。接入网设备接收到核心网设备发送的所述终端的下行数据后,根据其保存的所述终端的连接信息,确定所述终端的标识和接入网设备保存的所述终端在的网络小区的标识,以及确定终端和接入网设备之间的RRC连接的状态,当RRC连接处于空闲状态时,接入网设备向终端发送寻呼消息,寻呼消息中包括终端的标识。
步骤403:终端接收到寻呼消息后,与接入网设备建立连接。
步骤404:接入网设备向终端转发所述下行数据。
上述方法中,核心网设备维持的终端的连接一直处于连接状态,核心网设备收到应用服务器发给终端的下行数据后,不需要寻呼该终端以及和终端恢复网络连接,而是由接入网设备直接寻呼终端。具体的,接入网设备和核心网设备之间存在为该终端建立的控制面连接和用户面连接。接入网设备保 存为该终端建立的控制面连接和用户面连接的上下文信息,包括连接的标识、连接的状态(处于连接状态),处理该连接的核心网设备的标识或地址信息,连接的配置信息等。核心网设备保存为该终端建立的控制面连接和用户面连接的上下文信息,包括连接的标识、连接的状态(处于连接状态),处理该连接的接入网设备的标识或地址信息,连接的配置信息等。从而核心网设备接收应用服务器向终端发送的下行数据后,根据保存的终端用户面连接的配置信息确定所述用户面连接所对应的接入网设备的设备或标识,并将所述下行数据发送给所述接入网设备。通过该流程,避免了核心网设备处理网络连接的恢复操作,从而减少了核心网的负荷;减少了发送下行数据时需要的网络信令的数量,进而减少了终端接收到下行数据的时延。
可选的,本申请实施例中,终端在确定终端已经移动到移动管理策略对应的网络区域之外时,向核心网设备发送区域更新请求消息,用于指示所述终端所处的网络区域发生变更。所述区域更新请求消息中可以包括终端标识、变更前的网络区域的网络区域标识、变更后的网络区域的网络区域标识等信息,在此不再逐一描述。相应的,核心网设备在接收到区域更新请求消息之后,根据变更后的网络区域的网络区域标识以及终端的移动特征信息对终端的移动管理策略进行变更,并将变更后的移动管理策略指示给终端、接入网设备等设备。
下面通过具体的实施例详细描述上面的流程。

其中,网络区域标识可以是由第一请求消息中携带的,也可以是核心网设备根据第一请求消息中携带的终端的位置信息确定的。
步骤507:核心网设备向所述终端指示所述移动管理策略。
核心网设备可以通过向终端单独发送一个消息指示出所述移动管理策略;或者,核心网设备也可以通过现有的消息向所述终端指示所述移动管理策略,例如通过附着确认(Attach Acknowledgement)消息向所述终端指示所述移动管理策略。
步骤508:核心网设备向接入网设备指示所述移动管理策略。
需要说明的是,步骤507与步骤508的执行顺序并不限定。

第一请求消息中可以包括终端的位置信息、网络区域标识等信息。
步骤602:核心网设备根据终端的网络区域标识以及移动特征信息确定所述终端的移动管理策略。
其中,网络区域标识可以是由第一请求消息中携带的。
需要说明的是,该步骤中,移动特征信息为核心网设备预先存储的。
步骤603:核心网设备向所述终端指示所述移动管理策略。
核心网设备可以通过向终端单独发送一个消息指示出所述移动管理策略;或者,核心网设备也可以通过现有的消息向所述终端指示所述移动管理策略。
步骤604:核心网设备向接入网设备指示所述移动管理策略。
其中,步骤603和步骤604可以合并为一个步骤,此时核心网设备先向接入网设备指示所述移动管理策略,再由接入网设备向终端指示所述移动管理策略。
步骤605:终端向核心网设备发送确认消息,用于指示已经收到所述移动管理策略。
