触发网络策略更新的方法、管理功能实体及核心网设备
相关申请的交叉引用
本申请主张在2016年8月4日在中国提交的中国专利申请No.201610634585.1的优先权，其全部内容通过引用包含于此。
技术领域
本公开文本涉及通信技术领域，特别涉及一种触发网络策略更新的方法、管理功能实体及核心网设备。
背景技术
在NextGen(新一代)网络中进行策略控制时，需要由网络为终端生成网络策略，以控制终端的网络通信过程，该网络策略包括终端的移动性限制或PDU(Protocol Data Unit，协议数据单元)的连续性模式。
下面首先对终端的移动性限制和PDU的连续性模式进行说明如下：
1、终端的移动性限制
5G(5th Generation，第五代)网络需能够根据终端的移动性，差异化的提供移动性支持，因此网络需能够确定终端移动性限制，例如终端的移动性限制可分为无移动性、受限移动性和不受限移动性。
在确定终端的移动性限制时，网络可能需要参考终端的信息，例如签约信息、终端的位置以及终端所处的时段等。签约信息中记录了终端可能的移动性限制，例如记录终端在A地时，处于受限移动性；处于A地之外，处于不受限移动性。在确定终端的移动性限制时，首先，网络中的策略控制/管理功能获取终端签约信息中的终端可能的移动性限制，再根据终端当前的位置、当前的时间和当前正在使用的应用的特征，确定终端当前的移动性限制。
2、PDU会话的连续性模式
在5G网络中，终端请求建立PDU会话时，首先需要确定待建立PDU会话的连续性模式。终端主要通过所安装的应用软件的指示确定待建立PDU会话的连续性模式。随后，终端向网络提供所建立PDU会话的会话连续性模 式。
如果终端没有向网络指示待建立的PDU会话的会话连续性模式，那么网络需要为终端选择该PDU会话的连续性模式。
如图1所示，在LTE(Long Term Evolution，长期演进)网络中，应用功能(Application Function，AF)和策略与计费规则功能(Policy and Charging Rules Function，PCRF)之间的Rx接口可以用来传输应用层信息，包括应用的QoS(Quality of Service，服务质量)需求，应用的标识等，在Rx接口传输的应用层信息会被保存在PCRF中。但是相关技术中PCRF并没有从Rx接口中获取应用服务器中的终端的移动性信息和PDU会话的连续性要求。
需要说明的是，终端的移动性信息可能被应用服务器更准确的获取，例如能够获取终端移动规律或未来移动轨迹的应用服务器。这些终端的移动性信息应可以被网络用来更准确确定终端的移动性限制。然而目前确定终端的移动性限制的方法并没有考虑到可从应用层获取的终端移动性信息。
相关技术中，终端建立的PDU会话的连续性要求是基于终端软件的指示确定的，而没有考虑到用户的差异化服务的需求，即应用服务器针对不同用户可能提供不同的业务连续性要求，例如针对高价值客户提供较高的连续性保证，因此相关技术无法根据应用的需求提供业务连续性。
综上可知，相关技术无法做到利用应用层信息动态触发网络策略的更新。

具体实施方式
为使本公开文本实施例的目的、技术方案和优点更加清楚，下面将结合本公开文本实施例中的附图，对本公开文本实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开文本一部分实施例，而不是全部的实施例。基于本公开文本中的实施例，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，都属于本公开文本保护的范围。本公开文本针对相关技术中存在生成的网络策略不合适，且又无法做到利用应用层信息动态触发网络策略更新，进而影响网络通信的问题，提供一种触发网络策略更新的方法、管理功能实体及核心网设备。
如图2所示，本公开文本一些实施例中的触发网络策略更新的方法，应用于策略管理功能实体，包括：
步骤21，获取网络策略参数，所述网络策略参数由终端的应用层信息确定得到；
步骤22，根据所述网络策略参数，触发网络策略的更新。
通常情况下，在当前网络策略参数与获取的网络策略参数不一致或者是获取了新的网络策略参数时，才会触发网络策略的更新。
需要说明的是，该网络策略参数可以是策略管理功能实体根据接收的应用服务器发送的终端的应用层信息确定得到的，也可以是直接获取其他核心网设备传递的网络策略参数，该网络策略参数是由其他核心网设备根据接收的应用服务器的应用层信息确定得到的；还需要说明的是，本实施例中该应 用服务器的应用层信息主要包括终端的移动性信息和业务的连续性特征信息，其中，所述终端的移动性信息对应的网络策略参数为所述终端的移动性限制，所述业务的连续性特征信息对应的网络策略参数为PDU会话所需的连续性模式。
本公开文本实施例中，通过应用服务器的应用层信息获取网络策略参数，在由应用层信息确定的网络策略参数与当前网络策略参数不一致时，触发网络策略的更新，此种方式可以结合应用层信息，准确地判定当前网络策略是否符合网络的通信要求，在当前网络策略不符合通信要求时，实时地进行网络策略的更新，确保了网络策略的准确性，进而保证了网络通信的可靠性。
如图3所示，本公开文本一些实施例中的触发网络策略更新的方法，应用于策略管理功能实体，包括：
步骤31，接收应用服务器发送的终端的应用层信息；
需要说明的是，本实施例中，策略管理功能实体直接从应用服务器中获取应用层信息，该应用信息包括终端的移动性信息和业务的连续性特征信息。
步骤32，根据所述应用层信息，确定与所述应用层信息对应的网络策略参数；
步骤33，根据所述网络策略参数，触发网络策略的更新。
本实施例中，直接由策略管理功能实体根据应用层信息进行网络策略参数的获取，在获取的网络策略参数与当前网络策略参数不一致或者是获取了新的网络策略参数时，通常会向网络控制功能实体发送网络策略更新请求，网络控制功能实体根据策略管理功能实体发送的网络策略更新请求触发相应网络策略的更新。
还需要说明的是，通常为了使得应用服务器能准确发送应用层信息，在步骤31之前，本公开文本实施例的触发网络策略更新的方法，还包括：
发送订阅信息给所述应用服务器，所述订阅信息指示向所述应用服务器获取指定的应用层信息。
需要说明的是，策略管理功能实体会根据当前的业务需求，向某些特定的应用服务器发送应用信息订阅请求，该应用服务器可以为无人驾驶汽车的控制服务器，也可以为地图/导航服务器等，通常情况下，这些应用服务器在 对终端提供服务的同时，会基于策略管理功能实体的订阅信息，向策略管理功能实体提供终端的移动性信息，例如无人驾驶汽车的控制服务器提供无人驾驶汽车的移动轨迹。
具体地，当所述应用层信息包括终端的移动性信息时，所述步骤32的实现方式为：
根据终端的移动性信息，确定所述终端的移动性限制。
可选地，所述步骤33的具体实现方式为：
根据所述网络策略参数得到网络策略，并根据所述网络策略，触发网络策略的更新；或者
根据所述网络策略参数得到网络策略，保存所述网络策略，触发网络策略的更新。
需要说明的是，根据网络策略参数的不同，策略管理功能实体可能并不是实时地触发网络策略的更新。当策略管理功能实体判断不需要立即发起网络策略更新过程时，可先保存根据网络策略参数得到的网络策略，随后当策略管理功能实体判断需要触发网络策略的更新时再触发网络策略更新过程。
如图4所示，采用终端的移动性信息触发网络策略更新的具体过程为：
步骤4.1，策略管理功能实体向特定的应用服务器发送应用信息订阅请求；
步骤4.2，应用服务器接收到应用信息订阅请求后，向策略管理功能实体返回应用信息订阅确认信息，表示策略管理功能实体成功订阅应用服务器的应用层信息。
步骤4.3，应用服务器与终端进行应用层信息交互。
步骤4.4，应用服务器获取终端的移动性信息。
步骤4.5，应用服务器根据策略管理功能实体的订阅信息，将终端的移动性信息发送给策略管理功能实体。
步骤4.6，策略管理功能实体在成功接收终端的移动性信息后，向应用服务器发送确认消息。
步骤4.7，当策略管理功能实体收到应用服务器提供的终端的移动性信息(或移动规律)后，确定出终端所需的移动性限制并保存，例如某无人驾驶汽车在时段A处于行驶状态，在时段B处于停车状态，在时段C处于入库状 态，则策略管理服务器可将该无人驾驶汽车的车载终端的移动性支持级别分别定义为：时段A，高移动性支持；时段B，低移动性支持；时段C，无移动性支持。
步骤4.8，策略管理功能实体确定出终端当前所需的移动性限制与现有的移动性限制不一致，或者策略管理功能实体没有终端的移动性限制的信息时，向网络控制功能实体发出针对该终端的移动性限制的网络策略更新请求，该网络策略更新请求中携带有新确定的终端当前所需的移动性限制。
步骤4.9，网络控制功能实体在成功接收网络策略的更新请求时，向策略管理功能实体返回网络策略更新响应。
步骤4.10，网络控制功能实体在收到网络策略功能实体发来的针对移动性限制的网络策略更新请求后，对终端进行相应的移动性管理。
具体地，当所述应用层信息包括业务的连续性特征信息时，所述步骤32的实现方式为：
根据业务的连续性特征信息，确定PDU会话所需的连续性模式。
如图5所示，采用业务的连续性特征信息触发网络策略更新的具体过程为：
步骤5.1，应用服务器与终端进行应用层信息交互，以此获取业务的连续性特征信息。
步骤5.2，应用服务器将业务的连续性特征信息发送给策略管理功能实体。
步骤5.3，策略管理功能实体在成功接收业务的连续性特征信息后，向应用服务器发送确认消息。
需要说明的是，上述3个步骤主要传输的是应用服务器针对该终端特别设定的业务连续性要求(即业务的连续性特征信息)，例如针对高价值客户，提供更高的业务连续性。对于普通的应用的业务连续性要求可以是保存在网络中的，即应用服务器在确定了业务连续性要求之后通知策略管理功能实体，使得后者将收到的业务连续性要求保存在网络中。
步骤5.4，策略管理功能实体根据获得的业务的连续性要求信息，计算PDU会话所需的连续性模式。
步骤5.5，如果当前建立的PDU会话的连续性模式和PDU会话所需的连 续性模式不匹配，则策略管理功能实体向网络控制功能实体发起策略更新请求，该策略更新请求中携带有新确定的PDU会话所需的连续性模式。
步骤5.6，网络控制功能实体在成功接收网络策略的更新请求时，向策略管理功能实体返回网络策略更新响应。
步骤5.7，网络控制功能实体收到策略更新请求后，对PDU会话连续性模式进行更新，具体可以有两种方法获得所需的PDU会话：
1.使用新的连续性模式更新PDU会话；
2.删除原有PDU会话，通知终端重建该PDU会话。
本公开文本实施例，策略管理功能实体根据从应用服务器侧直接获取的应用层信息进行网络策略参数的制定，网络策略参数与当前网络策略参数不一致时，触发网络策略的更新，此种方式可以结合应用层信息，准确地判定当前网络策略是否符合网络的通信要求，在当前网络策略不符合通信要求时，实时地进行网络策略的更新，确保了网络策略的准确性，进而保证了网络通信的可靠性。
如图6所示，本公开文本一些实施例中的触发网络策略更新的方法，应用于策略管理功能实体，包括：
步骤61，获取核心网设备发送的网络策略参数；
需要说明的是，所述网络策略参数由所述核心网设备根据终端的应用层信息确定得到。
步骤62，根据所述网络策略参数，触发网络策略的更新。
需要说明的是，本实施例中步骤62的实现方式与参照图3描述的实施例中的步骤33的实现方式相同，在此不再进行详细的说明。

如图9所示，本公开文本一些实施例中的触发网络策略更新的方法，应用于核心网设备，包括：
步骤91，从应用服务器获取终端的应用层信息；
步骤92，根据所述应用层信息，获取所述应用层信息对应的网络策略参数；
需要说明的是，所述应用层信息包括终端的移动性信息和/或业务的连续性特征信息，其中，所述终端的移动性信息对应的网络策略参数为所述终端的移动性限制，所述业务的连续性特征信息对应的网络策略参数为PDU会话 所需的连续性模式；
步骤93，发送所述网络策略参数给签约管理功能实体或者策略管理功能实体，触发所述签约管理功能实体或者策略管理功能实体更新网络策略。
需要说明的是，在一些情况下，应用服务器与3GPP(3rd Generation Partnership Project，第三代合作伙伴项目)网络之间并不一定有直接的接口，例如LTE网络中的Rx接口，因此，此时需要应用服务器通过其他的核心网设备提供应用层信息，该核心网设备可以是能力开放平台。
具体地，所述步骤92的实现方式为：
对所述应用层信息进行分析和提取，将所述应用层信息转换成对应的网络策略参数。
需要说明的是，能力开放平台收到应用服务器的相关信息后，可能进行信息的分析和提取，将应用层信息转换成3GPP网络能够识别的信息，例如根据终端的移动性信息确定终端的移动性限制，根据业务的连续性要求确定出PDU会话的连续性模式。
如图10所示，本公开文本实施例的触发网络策略更新的方法的详细实现过程为：
步骤10.1，能力开放平台接收应用服务器中的终端或应用相关的信息，例如为包括终端的移动性信息和业务的连续性要求的应用层信息。
步骤10.2，能力开放平台在成功接收应用层信息后，向应用服务器发送确认消息。
步骤10.3，能力开放平台对接收的相关信息进行信息的分析和提取，将应用层信息转换成3GPP网络能够识别的信息，例如根据终端的移动性信息确定终端的移动性限制，根据应用的业务连续性要求确定出PDU会话的连续性模式。
步骤10.4，能力开放平台将移动性限制和/或PDU会话的连续性模式发送到策略管理功能实体中，收到信息的策略管理功能实体触发策略更新过程。
步骤10.5，策略管理功能实体在成功收到能力开放平台发送的信息后，反馈信息传输确认消息给能力开放平台。
步骤10.6，能力开放平台将移动性限制和/或PDU会话的连续性模式发 送到签约管理功能实体中，收到信息的签约管理功能实体触发网络策略更新过程。
步骤10.7，签约管理功能实体在成功收到能力开放平台发送的信息后，反馈信息传输确认消息给能力开放平台。
需要说明的是，步骤10.4和步骤10.6为不可并列的步骤，即能力开放平台会选择签约管理功能实体和策略管理功能实体中的一个进行信息的发送，具体的选用哪一个，由能力开放平台根据网络运行状态决定。
本公开文本实施例中，在应用服务器与3GPP网络之间并不存在直接的接口时，通过能力开放平台将应用服务器的应用层信息传递给网络中的签约管理功能实体或策略管理功能实体，同时为了减少签约管理功能实体和策略管理功能实体的工作负荷，能力开放平台需要先将应用层信息进行转换得到网络策略参数后，才进行传送，此种方式保证了可以将应用层信息顺利传递到核心网侧，也避免了签约管理功能实体和策略管理功能实体的负载较重，影响网络工作的问题。
