技术领域
本公开涉及移动通信领域，特别涉及一种动态触发接入和移动性策略更改的方法和系统。
背景技术
AM(Access and Mobility，接入和移动性)策略包括对SAR(Service Area Restrictions，服务区域限制)、RFSP(RAT/Frequency Selection Priority，无线接入/频率选择优先级)和UE-AMBR(UE Aggregated Maximum Bitrate，用户终端最大速率限制)等的管理，其中RFSP允许网络将特定服务引导至特定的无线接入资源上。
不同的应用程序对于无线资源要求不同，例如AR(Augmented Reality，增强现实)/VR(Virtual Reality，虚拟现实)等对速率和时延要求高的5G业务建议高频无线资源，而对移动性要求高且希望避免频繁切换的业务就可以选择低频无线资源(覆盖范围大)，所以不同业务的AM策略往往不同，由此导致了应用程序动态触发AM策略更改的需求。例如，在3GPP(3rd Generation Partnership Project，第三代合作伙伴计划)R16版本的标准中，应用程序能够动态触发SM(Session Management，会话管理)策略更改的场景。

图5为本公开另一个实施例的动态触发接入和移动性策略更改方法的流程示意图。
在步骤501，AF在预定应用开始或终止的情况下触发AM策略更改，生成AM策略授权更新请求，其中AM策略授权更新请求中至少包括UE ID、APP ID和ASP ID。
在步骤502，AF将AM策略授权更新请求发送给NEF实体。
在步骤503，NEF实体将AM策略授权更新请求发送给PCF实体。
在步骤504，PCF实体利用在本地预设的映射表，查询出与UE ID、APP ID和ASP ID相关联的RFSP索引值和TA列表信息。
在步骤505，PCF实体将AM策略控制更新通知发送给AMF实体。AM策略控制更新通知包括AM策略标识、以及RFSP索引值和TA列表信息。
在一些实施例中，AM策略标识与用户终端标识UE ID一一对应。
在步骤506，AMF实体通过N2消息将接收到的AM策略控制更新通知发送给接入网侧设备。
在步骤507，接入网侧设备根据RFSP索引值和TA列表信息执行相应的无线资源调度。
例如，接入网侧设备可以为AN侧设备或RAN侧设备。
通过实施本公开上述实施例，能够得到以下有益效果：
(1)填补了3GPP R16版本标准中，应用程序动态触发AM策略更改方法的空白；
(2)在PCF新增了RFSP映射表和SAR映射表，可以根据AF传递过来的信息方便地找到需要更改的RFSP索引值/SAR映射；
(3)通过利用NEF和PCF，使流程更加合理和完善。
在一些实施例中，在上面所描述的功能单元模块可以实现为用于执行本公开所描述功能的通用处理器、可编程逻辑控制器(Programmable Logic Controller，简称：PLC)、数字信号处理器(Digital Signal Processor，简称：DSP)、专用集成电路(Application Specific Integrated Circuit，简称：ASIC)、现场可编程门阵列(Field-Programmable Gate Array，简称：FPGA)或者其他可编程逻辑器件、分立门或者晶体管逻辑器件、分立硬件组件或者其任意适当组合。
本领域普通技术人员可以理解实现上述实施例的全部或部分步骤可以通过硬件来完成，也可以通过程序来指令相关的硬件完成，所述的程序可以存储于一种计算机可读存储介质中，上述提到的存储介质可以是只读存储器，磁盘或光盘等。
本公开的描述是为了示例和描述起见而给出的，而并不是无遗漏的或者将本公开限于所公开的形式。很多修改和变化对于本领域的普通技术人员而言是显然的。选择和描述实施例是为了更好说明本公开的原理和实际应用，并且使本领域的普通技术人员能够理解本公开从而设计适于特定用途的带有各种修改的各种实施例。
