技术领域
本申请涉及移动通信技术领域，尤其涉及一种通信方法、装置及系统。
背景技术
在现在的用户策略关联建立流程中，终端设备提供至策略控制网元的策略区块标识(Policy Section Identifier，PSI)列表需携带本地所保存的所有PSI，一个PSI对应一个或多个用户路由选择策略(UE Route Selection Policy，URSP)。对于终端设备未携带的PSI，策略控制网元将理解为终端设备上没有该PSI对应的URSP。
而在实际场景中，运营商可能以用户套餐粒度配置URSP，且运营商所配置到终端设备上的URSP对应的应用可能远多于终端设备上已安装或需要使用的应用，这样将导致终端设备实际需上报的PSI将远超出实际需要。
此外，由于策略控制网元需保证终端设备上的URSP最新，即使终端设备无需使用特定应用，当该应用所对应的URSP发生变更时，策略控制网元仍需持续对该URSP持续更新，而这一操作亦将导致无用的信令开销。
发明内容

如图2A所示，为基于服务化架构的第五代(5th generation，5G)网络架构示意图。图2A所示的5G网络架构中可包括三部分，分别是终端设备部分、数据网络(data network，DN)和运营商网络部分。下面对其中的部分网元的功能进行简单介绍说明。
其中，运营商网络可包括以下网元中的一个或多个：网络开放功能(network exposure function，NEF)网元、策略控制功能(policy control function，PCF)网元、统一数据管理(unified data management，UDM)网元、统一数据库(Unified Data Repository，UDR)、网络存储功能(Network Repository Function，NRF)网元、应用功能(application function，AF)网元、接入与移动性管理功能(access and mobility management function，AMF)网元、会话管理功能(session management function，SMF)网元、无线接入网(radioaccess network，RAN)以及用户面功能(user plane function，UPF)网元等。上述运营商网络中，除无线接入网部分之外的部分可以称为核心网络部分。
终端设备(terminal device)，也可以称为用户设备(user equipment，UE)，是一种具有无线收发功能的设备，可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。所述终端设备可以是手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端、增强现实(augmented reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。
上述终端设备可通过运营商网络提供的接口(例如N1等)与运营商网络建立连接，使用运营商网络提供的数据和/或语音等服务。终端设备还可通过运营商网络访问DN，使用DN上部署的运营商业务，和/或第三方提供的业务。其中，上述第三方可为运营商网络和终端设备之外的服务方，可为终端设备提供他数据和/或语音等服务。其中，上述第三方的具体表现形式，具体可根据实际应用场景确定，在此不做限制。
RAN是运营商网络的子网络，是运营商网络中业务节点与终端设备之间的实施系统。终端设备要接入运营商网络，首先是经过RAN，进而可通过RAN与运营商网络的业务节点连接。本申请中的RAN设备，是一种为终端设备提供无线通信功能的设备，RAN设备 也称为接入网设备。本申请中的RAN设备包括但不限于：5G中的下一代基站(g nodeB，gNB)、演进型节点B(evolved node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved nodeB，或home node B，HNB)、基带单元(baseBand unit，BBU)、传输点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)、移动交换中心等。

PCF网元，主要负责针对会话、业务流级别进行计费、QoS带宽保障及移动性管理、UE策略决策等策略控制功能。该架构中，AMF与SMF所连接的PCF分别对应AM PCF(PCF for Access and Mobility Control)和SM PCF(PCF for Session Management)，在实际部署场景中可能不是同一个PCF实体。
NRF网元，可用于提供网元发现功能，基于其他网元的请求，提供网元类型对应的网元信息。NRF还提供网元管理服务，如网元注册、更新、去注册以及网元状态订阅和推送等。
DN，是位于运营商网络之外的网络，运营商网络可以接入多个DN，DN上可部署多种业务，可为终端设备提供数据和/或语音等服务。例如，DN是某智能工厂的私有网络，智能工厂安装在车间的传感器可为终端设备，DN中部署了传感器的控制服务器，控制服务器可为传感器提供服务。传感器可与控制服务器通信，获取控制服务器的指令，根据指令将采集的传感器数据传送给控制服务器等。又例如，DN是某公司的内部办公网络，该公司员工的手机或者电脑可为终端设备，员工的手机或者电脑可以访问公司内部办公网络上的信息、数据资源等。
图2A中Nnef、Npcf、Nudm、Naf、Namf、Nsmf、N1、N2、N3、N4，以及N6为接口序列号。这些接口序列号的含义可参见第三代合作伙伴计划(3rd generation partnership project，3GPP)标准协议中定义的含义，在此不做限制。
如图2B所示，为基于点对点接口的5G网络架构示意图，其中的网元的功能的介绍可以参考图2A中对应的网元的功能的介绍，不再赘述。图2B与图2A的主要区别在于：图2B中的各个网元之间的接口是点对点的接口，而不是服务化的接口。
在图2B所示的架构中，各个网元之间的接口名称及功能如下：
1)、N7：PCF与SMF之间的接口，用于下发协议数据单元(protocol data unit，PDU)会话粒度以及业务数据流粒度控制策略。
2)、N15：PCF与AMF之间的接口，用于下发UE策略及接入控制相关策略。

进一步地，当前3GPP标准中定义了两种用户在拜访地接入的漫游方式，即归属地接入漫游(Home-routed Roaming)与本地接入漫游(Local Breakout Roaming)两种方式，以图2B所示的5G架构为例，则Home-routed漫游架构和Local Breakout漫游架构分别如图2C与图2D所示。
参考图2C所示的Home-routed漫游架构，该漫游架构图中，AMF与SMF分别位于拜访地和归属地，会话管理功能则由支持与UDM/H-PCF交互的归属地H-SMF执行。此外，V-PCF所连接的H-PCF与H-SMF所连接的H-PCF，在实际应用场景中可能不是同一个PCF实体。需要说明的是，本申请方案所涉及的URSP既可以支持由该架构中的H-PCF提供，也可以由该架构中的V-PCF提供。
参考图2D所示的Local Breakout漫游架构，该漫游架构图中，AMF、SMF均位于拜访地，此时会话管理功能即由拜访地的SMF功能实体执行。此外，AMF所连接的V-PCF与SMF所连接的V-PCF，在实际应用场景中可能不是同一个PCF实体。需要说明的是，本申请方案所涉及的URSP当前标准中既可以支持由该架构中的H-PCF提供，也可以由该架构中的V-PCF提供。
可以理解的是，上述网元或者功能既可以是硬件设备中的网络元件，也可以是在专用硬件上运行软件功能，或者是平台(例如，云平台)上实例化的虚拟化功能。可选的，上述网元或者功能可以由一个设备实现，也可以由多个设备共同实现，还可以是一个设备内的一个功能模块，本申请实施例对此不作具体限定。
本申请中的移动性管理网元、会话管理网元、策略控制网元、应用功能网元、接入网设备、网络开放功能网元、用户面网元、数据存储网元分别可以是图2A、图2B、图2C或图2D中的AMF、SMF、PCF、AF、RAN、NEF、UPF、UDR，也可以是未来通信如第六代(6th generation，6G)网络中具有上述AMF、SMF、PCF、AF、RAN、NEF、UPF、 UDR的功能的网元，本申请对此不限定。为方便说明，本申请以移动性管理网元、会话管理网元、策略控制网元、应用功能网元、接入网设备、网络开放功能网元、用户面网元、数据存储网元分别为上述AMF、SMF、PCF、AF、RAN、NEF、UPF、UDR为例进行说明。进一步地，本申请中将终端设备简称为UE。
为便于理解本申请方案，下面首先对相关背景技术进行介绍说明。
一、通用的用户注册流程
通用的用户注册流程可简单描述为：UE通过AN发送注册请求至AMF，AMF根据用户标识向特定UDM获取签约数据，UDM收到该请求后可向UDR获取实际签约数据。此外，AMF还可向PCF发起用户策略关联建立请求(UEPolicyControl_Create Request)及接入管理策略关联建立请求(AMPolicyControl_Create Request)，分别用于获取UE策略及接入控制策略。PCF在该过程中返回接入控制策略至AMF，以及经由AMF向UE提供UE策略。
二、通用的会话建立流程
通用的会话建立流程可简单描述为：UE通过RAN发送会话建立请求到AMF，AMF为该会话选择SMF为其提供服务，保存SMF与PDU会话的对应关系，并将会话建立请求发送至SMF，SMF为UE选择相应UPF并建立用户面传输路径，并为其分配IP地址。在此过程中，SMF还将向PCF发起策略控制会话建立请求，用于在SMF和PCF间建立策略控制会话。在策略控制会话建立过程中，SMF将保存策略控制会话与PDU会话间的对应关系。此外，AF还可与PCF间建立AF会话，由PCF对AF会话与策略控制会话进行绑定。
三、UE策略机制
当前标准中定义了两种用户策略，分别为接入网络发现与选择策略(Access Network Discovery and Selection Policy，ANDSP)和URSP策略。其中，前者可同时由H-PCF与V-PCF提供，主要用于指示UE选择非3GPP(Non-3GPP)接入网络信息，如接入网络、接入节点等信息。后者则仅支持由H-PCF提供，主要用于UE决策如何为待传输业务数据流选择路由策略，如业务流是否支持分流至Non-3GPP接入，或是选择特定数据网名称(Data Network Name，DNN)，单网络切片选择辅助信息(single network slice selection assistance information，S-NSSAI)，会话与业务连续性模式(Session and Service Continuity mode，SSC mode)等信息用于传输该业务数据流。本申请方案主要针对URSP场景进行展开。
此外，为了降低UE与PCF间更新用户策略时的信令量，PCF可将一条或多条URSP组成一个PSI，和/或，将一条或多条ANDSP组成一个PSI，并在下发用户策略时将PSI及对应的UE策略提供至UE。后续UE判断需提供本地所保存的URSP至PCF时，仅需携带PSI列表(PSI list)即可，PCF也可以以PSI为单位对对应的用户策略进行操作，如修改、删除等动作。
URSP结构主要由两部分内容组成：流描述信息(Traffic descriptor)和路由选择描述信息列表(List of Route Selection Descriptors)。其中，流描述信息例如包括操作系统标识(OS ID)、应用的标识(APP ID)、IP三元组、域描述信息等等。路由选择描述信息包括S-NSSAI、DNN、SSC mode等等。
四、UE执行URSP匹配的过程
当UE判断需发起特定业务或应用时，将根据URSP规则的优先级，按顺序将待发起的业务或应用与所收到的URSP规则中的流描述信息进行匹配，若匹配到具体的URSP规则(该URSP规则也可能是默认URSP规则，如流描述信息为Match-all形式)，则UE还需判断是否已有PDU会话符合该URSP中的路由选择描述信息的定义：
1)、如果已有PDU会话所对应的DNN，S-NSSAI，SSC mode等信息与所匹配URSP规则所对应的路由选择描述信息中的对应信息均一致，则UE可以选择在已有PDU会话的基础上发起PDU会话修改请求，该PDU会话修改请求中可携带参数包括当前PDU Session ID，N1 SM Container(PDU Session Modification Request(PDU Session ID，packet filters，Operation，Requested QoS))；其中PDU Session ID用于AMF关联至具体会话上下文，N1 SM Container则由AMF透传至SMF，以指示UE所希望发起的具体业务以及该业务所需要得到的QoS保障。
2)、如果已有PDU Session(s)均无法与该URSP的RSD信息匹配，则UE将为该业务/应用发起PDU会话建立请求，并在发送至AMF的请求消息中携带新分配的PDU Session ID及RSD中的DNN，S-NSSAI，N1 SM Container(SSC mode，PDU Session Type)等参数；其中，新分配的PDU Session ID用于标识该PDU会话建立请求所对应的PDU会话，DNN+S-NSSAI则作为AMF为该PDU会话建立请求选择SMF实体的参数，N1 SM Container则由AMF透传至所选择的SMF。
五、UE策略下发流程
如图3所示，为现有技术中的用户策略下发流程示意图。该示意图描述的是PCF如何下发用户策略至UE的流程，可同时适用于初始请求或更新请求场景下PCF提供用户策略至UE。
该流程具体描述如下：
步骤300，PCF收到AMF所发起的用户策略关联建立请求后，决策需更新UE上的用户策略，或是PCF根据事件触发决策需更新UE上的用户策略。
步骤301，PCF向AMF发送更新的用户策略。相应地，AMF可以接收到更新的用户策略。
具体的，PCF调用AMF的服务，通过Namf_Communication_N1N2MessageTransfer消息发送更新的用户策略至AMF。
步骤302，若UE处于空闲状态，则AMF还需发起网络侧触发的业务请求(Network Triggered Service Request)流程以使得UE进入连接态。
该步骤可选。
步骤303，AMF经由RAN向UE发送更新的用户策略。
步骤304，UE在响应消息中携带用户策略送达报告至AMF。
步骤305，AMF转发所收到的用户策略送达报告至PCF。
具体的，AMF可以调用通过Namf_N1MessageNotify消息，向PCF发送用户策略送达报告。
PCF需维护发送至UE的最新的用户策略内容，并在用户策略关联释放时将该信息保存至UDR中。
六、用户策略关联建立流程
如图4所示，为现有技术的用户策略关联建立流程示意图。当UE初始注册至5G网 络，或从第四代(4th generation，4G)网络切换至5G网络时，UE需提供本地所保存的PSI列表至PCF，以使得PCF得以判断是否需对UE上的URSP进行更新，具体过程可以参照下图所示。
该过程可简单描述如下：
步骤401，AMF决策需建立UE策略关联(decision to establish UE Policy Association)。
具体的，AMF接收UE所发送的注册请求，该注册请求可以是UE在5G初始注册所对应的注册请求，也可以是UE从4G切换至5G所发起的移动性注册请求(Mobility Registration)。在该注册请求中，UE需携带本地所保存的PSI list，以告知PCF本地所保存的用户策略列表，该PSI list在UE Policy Container中发送至AMF，即UE Policy Container(List of stored PSIs，OS ID，the indication of UE support for ANDSP)，其中，the indication of UE support for ANDSP用于指示是否支持ANDSP。该container经由AMF透明转发至PCF。
步骤402，AMF向V-PCF(若为非漫游场景，则为PCF)发送用户策略关联建立请求(Npcf_UEPolicyControl_Create Request)，其中可包含永久签约标识(Subscription Permanent Identifier，SUPI)、永久设备标识(Permanent Equipment Identifier，PEI)、接入方式(Access Type)、无线接入类型(RAT Type)，以及UE Policy Container(List of stored PSIs，OS ID，indication of UE support for ANDSP)。
步骤403，V-PCF将转发该用户策略关联建立请求至H-PCF。
步骤404，H-PCF返回用户策略关联建立响应(Npcf_UEPolicyControl_Create Response)至V-PCF，其中携带事件订阅信息。
步骤405，V-PCF返回用户策略关联建立响应至AMF，其中携带从H-PCF所收到的事件订阅信息。
可选地，V-PCF还可增加订阅其他事件。
步骤406至步骤408，H-PCF从UDR中获取策略签约相关信息，其中包含UDR中所保存PSI及对应的策略内容及此前所保存的OS ID、ANDSP能力指示等信息，并执行相应策略决策，判断是否需对UE上所保存的UE策略执行更新。
若需更新UE上所保存的用户策略，则：
漫游场景下H-PCF通过UpdateNotify消息提供更新的用户策略至V-PCF，由V-PCF触发UE配置更新流程(UE Configuration Update procedure)更新UE上的用户策略。
非漫游场景下，H-PCF触发UE配置更新流程更新UE上的用户策略。
步骤409至步骤410，漫游场景下，V-PCF收到AMF所返回的用户策略送达报告，则还将该用户策略送达报告携带于用户策略更新请求发送至H-PCF。相应的，H-PCF向V-PCF返回用户策略更新响应。
上述图4所示的用户策略关联建立流程中，UE提供至PCF的list of PSI需携带本地所保存的所有PSI ID，对于UE未携带的PSI，PCF将理解为UE上没有该PSI对应的用户策略。而在实际场景中，运营商可能以用户套餐粒度配置URSP，且运营商所配置到UE上的URSP对应的应用可能远多于UE上已安装或可能使用的应用列表，这样将导致UE实际需上报PSI列表将远超出实际需要。
此外，由于PCF需保证UE上的URSP最新，即使UE无需使用特定应用，当该应用所对应的URSP发生变更(如应用服务器发生变更导致Traffic Descriptor需执行更新，或 是用户位置发生变更，导致RSD中路由选择描述信息需进行更新)时，PCF仍需持续对该URSP持续更新，而这一操作亦将导致无用的信令开销。
基于此，本申请提出了一种用户侧辅助PCF执行URSP决策的方案，以避免UE及PCF侧持续更新和维护UE无需使用的URSP所带来的信令开销。
下面对本申请提供的通信方法进行说明。基于图1、图2A至图2D任一架构，如图5A所示，为本申请提供的一种通信方法流程示意图。该方法包括以下步骤：
步骤501a,UE向PCF发送第一信息。相应地，PCF可以接收到该第一信息。
该第一信息为禁止的应用的标识、或禁止的PSI、或禁止的URSP的标识、或允许的应用的标识。
其中，应用的标识用于识别应用的信息，比如可以是APP ID、APP的三元组、或域名描述信息等。一个PSI对应一个或多个URSP。
步骤502a，PCF从UDR获取UE的第一URSP。
步骤503a，PCF根据第一信息和第一URSP，确定UE的第二URSP。
基于上述方案，PCF在决策UE的URSP时，考虑了UE上报的第一信息，从而为UE确定出合适的URSP，并且有助于避免UE及PCF侧持续更新和维护UE无需使用的URSP所带来的信令开销。
下面根据第一信息的具体内容，分情形进行说明。
情形一，第一信息为禁止的应用的标识。
基于该情形，在第一种实现方法中，上述步骤503a比如可以是：PCF根据第一信息确定第三URSP，然后PCF根据第三URSP和第一URSP，确定第二URSP，第二URSP不包括第三URSP。
基于该情形，在第二种实现方法中，PCF还从UDR获取UE的第二信息，第二信息为UDR上存储的UE的禁止的应用的标识，则上述步骤503a比如可以是：PCF根据第一信息、第二信息和第一URSP，确定第二URSP，第二URSP不包括第二信息对应的URSP和所述第一信息对应的URSP。
下面结合一个具体示例，对上述两种不同的实现方法进行说明。
1)、PCF从UE接收到的第一信息(即禁止的应用的标识)包括：APP ID1，并且APP ID1对应的URSP为URSP1；
2)、PCF从UDR获取到的第一URSP包括：URSP1、URSP2、URSP3、URSP4和URSP5；
3)、UDR中当前存储的第二信息(即禁止的应用的标识)包括：APP ID2和APP ID3，并且APP ID2对应的URSP为URSP2，APP ID3对应的URSP为URSP3。
基于上述第一种实现方法，则PCF先确定第一信息对应的URSP，即为URSP1，从而在第一URSP中排除掉URSP1，得到第二URSP，即第二URSP包括：URSP2、URSP3、URSP4和URSP5。
基于上述第二种实现方法，则PCF先根据第一信息和第二信息确定合并的禁止的应用的标识，即为APP ID1、APP ID2和APP ID3，然后确定对应的URSP，即为URSP1、URSP2和URSP3，从而在第一URSP中排除掉URSP1、URSP2和URSP3，得到第二URSP，即第二URSP包括：URSP4和URSP5。
可以看出，上述两种实现方法的主要区别在于：在第一种实现方法中，仅排除了UE 上报的禁止的应用的标识所对应的URSP，而在第二种实现方法中，不仅排除了UE上报的禁止的应用的标识所对应的URSP，还排除了UDR中存储的该UE的禁止的应用的标识所对应的URSP。
情形二，第一信息为禁止的PSI。
基于该情形，在第一种实现方法中，上述步骤503a具体为：PCF根据禁止的PSI确定禁止的应用的标识，根据禁止的应用的标识确定第三URSP，然后PCF根据第三URSP和第一URSP，确定第二URSP，第二URSP不包括第三URSP。
基于该情形，在第二种实现方法中，PCF还从UDR获取UE的第二信息，第二信息为UDR上存储的UE的禁止的应用的标识，则上述步骤503a具体为：PCF根据第一信息、第二信息和第一URSP，确定第二URSP，第二URSP不包括所述第二信息对应的URSP和所述第一信息对应的URSP。
下面结合一个具体示例，对上述两种不同的实现方法进行说明。
1)、PCF从UE接收到的第一信息(即禁止的PSI)包括：PSI1，并且PSI1对应的禁止的应用的标识为APP ID1，且APP ID1对应的URSP为URSP1；
2)、PCF从UDR获取到的第一URSP包括：URSP1、URSP2、URSP3、URSP4和URSP5；
3)、UDR中当前存储的第二信息(即禁止的应用的标识)包括：APP ID2和APP ID3，并且APP ID2对应的URSP为URSP2，APP ID3对应的URSP为URSP3。
基于上述第一种实现方法，则PCF先确定第一信息对应的URSP，即为URSP1，从而在第一URSP中排除掉URSP1，得到第二URSP，即第二URSP包括：URSP2、URSP3、URSP4和URSP5。
基于上述第二种实现方法，则PCF先根据第一信息确定禁止APP ID1，然后根据禁止的APP ID1和第二信息确定合并的禁止的应用的标识，即为APP ID1、APP ID2和APP ID3，然后确定对应的URSP，即为URSP1、URSP2和URSP3，从而在第一URSP中排除掉URSP1、URSP2和URSP3，得到第二URSP，即第二URSP包括：URSP4和URSP5。
可以看出，上述两种实现方法的主要区别在于：第一种实现方法仅排除了UE上报的禁止的PSI所对应的URSP，而第二种实现方法不仅排除了UE上报的禁止的PSI所对应的URSP，还排除了UDR中存储的该UE的禁止的应用的标识对应的URSP。
情形三，第一信息为禁止的URSP的标识。
基于该情形，在第一种实现方法中，上述步骤503a具体为：PCF删除所述第一URSP中与所述第一信息对应的URSP，得到第二URSP。
基于该情形，在第二种实现方法中，PCF还从UDR获取UE的第二信息，第二信息为UDR上存储的UE的禁止的应用的标识，则上述步骤503a具体为：PCF根据第一信息、第二信息和第一URSP，确定第二URSP，第二URSP不包括第二信息对应的URSP，也不包括第一信息对应的URSP。
下面结合一个具体示例，对上述两种不同的实现方法进行说明。
1)、PCF从UE接收到的第一信息(即禁止的URSP的标识)包括：URSP1ID；
2)、PCF从UDR获取到的第一URSP包括：URSP1、URSP2、URSP3、URSP4和URSP5；
3)、UDR中当前存储的第二信息(即禁止的应用的标识)包括：APP ID2和APP ID3，并且APP ID2对应的URSP为URSP2，APP ID3对应的URSP为URSP3。
基于上述第一种实现方法，PCF在第一URSP中排除掉URSP1，得到第二URSP，即 第二URSP包括：URSP2、URSP3、URSP4和URSP5。
基于上述第二种实现方法，PCF确定第二信息对应的URSP包括URSP2和URSP3，从而在第一URSP中排除掉URSP1、URSP2和URSP3，得到第二URSP，即第二URSP包括：URSP4和URSP5。
可以看出，上述两种实现方法的主要区别在于：在第一种实现方法中，仅排除了UE上报的禁止的URSP的标识对应的URSP，而在第二种实现方法中，不仅排除了UE上报的禁止的URSP的标识所对应的URSP，还排除了UDR中存储的该UE的禁止的应用的标识所对应的URSP。
针对上述情形一至情形三，PCF还可以根据第一信息和第二信息，确定更新后的禁止的应用的标识；然后将更新后的禁止的应用的标识存储至UDR。结合上述示例，则UDR中存储的该UE的更新后的禁止的应用的标识包括：APP ID1、APP ID2和APP ID3。
针对上述情形一至情形三，作为一种实现方法，上述步骤501a比如可以是：UE在注册流程中，向PCF发送上述第一信息。
情形四，第一信息为允许的应用的标识。
基于该情形，在一种实现方法中，上述步骤503a具体为：PCF根据第一信息确定第一信息对应的URSP为第四URSP，则PCF确定第二URSP包括该第四URSP，进一步的，第二URSP还可以包括第一URSP中的URSP。即PCF决策的UE的最新的URSP(即第二URSP)，一方面包括UE上报的允许的应用的标识对应的URSP(可以理解为新增的URSP)，另一方面还可以包括之前发送给UE的URSP(可以理解为UE的历史的URSP)。
下面结合一个具体示例，对上述实现方法进行说明。
1)、PCF从UE接收到的第一信息(即允许的应用的标识)包括：APP ID4，且APP ID4对应的URSP为URSP6；
2)、PCF从UDR获取到的第一URSP包括：URSP1、URSP2、URSP3、URSP4和URSP5；
基于上述实现方法，第二URSP包括URSP6，可选的，第二URSP还可以包括URSP1、URSP2、URSP3、URSP4和URSP5中的URSP。
针对上述情形四，作为一种实现方法，上述步骤501a比如可以是：UE在注册流程或在UE主动发起的用户策略更新流程中，向PCF发送上述第一信息。
需要说明的是，在具体实现中，UE还可以向PCF发送UE中的当前URSP，比如可以是以PSI的形式发送。下面以上述情形三为例，结合具体示例，介绍一种更新UE上的URSP的实现方法。需要说明的是，以下各个示例中的数字1，2，3，4，5分别为URSP1、URSP2、URSP3、URSP4、URSP5的简写。
在一个示例中，UE携带Banned List(1,2)，UE携带的PSI为PSI A(1,2,3)、PSI B(4)，UDR中所保存的为PSI A(1,2,3)、PSI C(4,5)。PCF决策得到最终URSP策略为(3,4,5)，此时PCF可采用PSI C(4,5)+PSID(3)+PSI A()+PSI B()的方式更新UE上的URSP；或直接以PSI D(3,4,5)+PSI A()+PSI B()的形式更新UE上的URSP。这里的PSI A()表示删除UE上的PSI A，PSI B()表示删除UE上的PSI B。
在又一个示例中，若上述UE携带Banned List(4)，UE携带的PSI为PSI A(1,2,3)，PSI B(4)，UDR中所保存的为PSI A(1,2,3)，PSI C(4,5)。PCF决策得到最终URSP策略为(1,2,3,5)，此时PCF可采用PSI D(1,2,3,5)+PSI A()+PSI B()的方式更新UE上的URSP；或是以PSI D(5)+PSI B()的方式更新UE上的URSP。
需要说明的是，上述示例中没有结合UDR中存储的UE的禁止的应用的标识。对于结合UDR中存储的UE的禁止的应用的标识的示例，不再赘述。其中，PCF还可更新UDR中所保存的为Banned List信息。
基于图1、图2A至图2D任一架构，如图5B所示，为本申请提供的又一种通信方法流程示意图。该方法包括以下步骤：
步骤501b，PCF向UE发送第一URSP。相应地，UE可以接收到该第一URSP。
步骤502b，UE向PCF发送用户策略送达报告，用户策略送达报告包含第一信息，第一信息为禁止的应用的标识、或禁止的PSI、或禁止的URSP的标识。相应地，PCF可以接收到该用户策略送达报告。
步骤503b，PCF根据第一信息，更新UDR中存储的UE的禁止的应用的标识，该禁止的应用的标识用于PCF执行用户策略决策，以避免向UE提供该禁止的应用的标识所对应的URSP。
基于上述方案，PCF在向UE发送URSP之后，UE可以在用户策略送达报告中携带第一信息，然后PCF根据第一信息更新UDR中存储的禁止的应用的标识，以便于PCF在下一次向UE提供URSP时，可以参考UDR中存储的禁止的应用的标识，以避免向UE提供禁止的应用的标识对应的URSP。其中，PCF在下一次确定URSP时的具体实现方法，可以参考图5A实施例中结合UDR中存储的禁止的应用的标识的方法，这里不再赘述。该方案为UE确定出合适的URSP，并且有助于避免UE及PCF侧持续更新和维护UE无需使用的URSP所带来的信令开销。
上述步骤503b中，PCF根据第一信息，更新UDR中存储的禁止的应用的标识，比如可以是：PCF从UDR获取第二信息，第二信息为UDR中存储的禁止的应用的标识；PCF根据第一信息和第二信息确定第三信息，第三信息包括至少一个禁止的应用的标识；PCF将第三信息存储至UDR，第三信息用于PCF执行用户策略决策，以避免向UE提供第三信息对应的URSP。作为示例，PCF根据第一信息确定的应用的标识包括APP ID1、APP ID2，UDR中存储的第二信息包括APP ID3、APP ID4，则PCF确定的第三信息包括APP ID1、APP ID2、APP ID3、APP ID4，从而UDR中存储的更新后的禁止的应用的标识包括：APP ID1、APP ID2、APP ID3、APP ID4。
作为一种实现方法，上述步骤502b之后，PCF还可以根据第一信息，确定URSP，然后根据该URSP更新UDR中存储的URSP。比如，UDR中存储的URSP包括URSP1、URSP2、URSP3、URSP4，PCF根据第一信息确定的URSP包括URSP1和URSP2，则UDR中存储的更新后的URSP包括：URSP3、URSP4。
需要说明的是，在具体实现中，UE还可以向PCF发送UE中的当前URSP，比如可以是以PSI的形式发送。针对上述情形四，下面结合具体示例，介绍一种更新UE上的URSP的实现方法。
在一个示例中，UE携带Allowed List(6)，UE携带的PSI为PSI A(1,2,3)，PSI B(4)，UDR中所保存的为PSI A(1,2,3)，PSI C(4)。PCF决策得到最终URSP策略为(1,2，3,4,6)，此时PCF可采用PSI D(4,6)+PSI B()的方式更新UE上的URSP；或直接以PSI D(1,2，3,4,6)+PSI A()+PSI B()的形式更新UE上的URSP。
下面结合具体示例，对上述图5A和图5B所示的流程进行介绍说明。
如图6所示，为本申请提供的又一种通信方法流程示意图。该方案是图5A所示的方法的一种具体实现。该方案是对图4所示的用户策略关联建立流程进行改进。该方案提出UE在请求消息中上报禁止的PSI或禁止的应用的标识(APP ID)，以告知PCF：UE无需使用该部分PSI或APP，从而避免由于UE与PCF侧不得不持续更新和维护UE无需使用的URSP所带来的信令开销。
其中，对于漫游场景，该流程图中PCF可以是V-PCF或是H-PCF，即V-PCF和H-PCF均可根据UE所上报的禁止的PSI或禁止的APP ID执行URSP决策，并提供更新的URSP至UE；也可以是V-PCF+H-PCF，即V-PCF在收到UE所发送的UE Policy Container后除执行流程图中所描述的动作外，还可将该UE Policy Container转发至H-PCF，由H-PCF执行流程图中所描述的动作。
该方法包括以下步骤：
步骤601，UE向AMF注册请求。相应地，AMF可以接收到该注册请求。
该注册请求可以是UE在5G初始注册所对应的注册请求，也可以是UE从4G切换至5G所发起的移动性注册请求(Mobility Registration)。在该注册请求中，UE携带PSI list(List of stored PSIs)，以告知PCF本地所保存的用户策略列表，以及还携带UE禁止的PSI或禁止的APP ID。其中，一个PSI对应一个或多个URSP。
具体的，注册请求中携带UE策略容器(UE Policy Container)，该UE Policy Container中包含List of stored PSIs，以及包含禁止的PSI或禁止的APP ID。可选的，该UE Policy Container中还包含OS ID，the indication of UE support for ANDSP。
其中，禁止的PSI指的是UE本地保存的PSI中无需使用的PSI。禁止的APP ID则是UE上无需使用或未安装的应用的标识，这里的APP ID可以是流描述信息形式，也可以是URSP Rule ID形式。
UE确定禁止的PSI的方式可以是：UE根据此前所收到的URSP列表，结合本地所安装或需要使用的应用，判断无需使用的部分URSP，从而得到禁止的PSI。一个禁止的PSI对应一个或多个禁止的URSP。作为一种实现方式，若注册请求中携带禁止的PSI，则禁止的PSI可以是以集合或列表的形式携带的。比如，以列表形式携带时，则携带一个Banned list of PSI。
UE确定禁止的应用的方式可以是：UE结合本地所安装或需要使用的应用，确定不需要使用或无需安装的应用，得到禁止的应用。作为一种实现方式，若携带禁止的APP ID，则禁止的APP ID可以是以集合或列表的形式携带的。比如，以列表形式携带时，则携带一个Banned list of APP ID。
需要说明的是，若注册请求中携带禁止的PSI，则上述PSI list可以是一个完整的PSI列表，即UE本地保存的所有的PSI构成的列表；或者，上述PSI list也可以是完整的PSI列表中除去禁止的PSI之外的PSI构成的列表。作为一个示例，假设UE本地保存的完整的PSI列表包括PSI1、PSI2、PSI3、PSI4和PSI5，其中PSI1和PSI2为禁止的PSI，则在一种实现方法中，上述注册请求的UE Policy Container中携带得到PSI list和禁止的PSI分别为{PSI1、PSI2、PSI3、PSI4和PSI5}和{PSI1、PSI2}；在又一种实现方法中，上述注册请求的UE Policy Container中携带得到PSI list和禁止的PSI分别为{PSI3、PSI4和PSI5}和{PSI1、PSI2}。
步骤602，AMF执行注册流程，并在注册成功后向UE发送注册响应。相应地，UE可以接收到注册响应。
步骤603，AMF向PCF发送用户策略关联建立请求。相应地，PCF可以接收到用户策略关联建立请求。
该用户策略关联建立请求中携带上述UE Policy Container，该UE Policy Container中包含PSI list，以及携带禁止的PSI或禁止的APP ID。
步骤604，若UE Policy Container中包含禁止的PSI，则PCF确定禁止的PSI中各PSI分别对应的APP ID，得到禁止的APP ID。
步骤605，PCF从UDR中获取策略数据，该策略数据包含UDR中所保存的用户策略信息，该用户策略信息包含URSP。
可选地，该用户策略信息还可以包含UE之前所上报的禁止的APP或禁止的PSI。
若从UDR获取到UE之前所上报的禁止的PSI，则PCF还需要确定禁止的PSI对应的禁止的APP ID。
步骤606，PCF决策生成URSP。
具体的，若PCF确定UE发送的PSI列表对应的URSP与PCF从UDR获取的URSP不同，则确定需要重新生成URSP。
PCF重新生成URSP的方法包括但不限于以下两种方法：
方法一，PCF根据禁止的APP ID(可以是步骤601携带的或步骤604确定的)，确定禁止的APP ID所对应的URSP，然后将从UDR中获取的URSP中去除禁止的APP ID所对应的URSP，得到重新生成的URSP。
方法二，PCF根据禁止的APP ID(可以是步骤601携带的或步骤604确定的)和从UDR获取的禁止的APP ID，得到合并后的禁止的APP ID，然后确定合并后的禁止的APP ID所对应的URSP，然后将从UDR中获取的URSP中去除禁止的APP ID所对应的URSP，得到重新生成的URSP。
步骤607，PCF向AMF发送用户策略关联建立响应。相应地，AMF可以接收到该用户策略关联建立响应。
该用户策略关联建立响应可携带PCF向AMF订阅的触发事件列表。
该步骤607可以是在步骤603之后步骤608之前的任意步骤执行。
步骤608，PCF在UE配置更新流程中将步骤606中生成的URSP发送至UE。
步骤609，UE在发起特定业务时，根据所接收到的URSP执行PDU会话建立流程/修改流程。
步骤610，当PCF完成URSP决策、或是接收到AMF所发送的用户策略关联释放请求消息后，PCF可以将本地所决策的最新的URSP以及决策的最终的禁止的APP ID发送至UDR进行保存。
可选的，还可以在此过程中将OS ID、indication of UE Support for ANDSP等信息存储至UDR。
上述实施例中，提出了一种用户侧辅助PCF执行URSP决策的方案，通过提供本地禁止的应用的标识或禁止的PSI，以避免UE与PCF侧持续更新和维护UE无需使用的URS所带来的信令开销。
如图7所示，为本申请提供的又一种通信方法流程示意图。该方案是图5B所示实施例的一种具体实现方式。
该方案可看作图6实施例的补充场景，不同于图6实施例的地方在于：该场景下UE在收到URSP后在用户策略送达报告中返回禁止的APP ID或禁止的PSI。其中，图7所示的实施例可以与图6所示的实施例相结合实施例，也可以是单独实施。
在漫游场景下，该流程图中PCF对应的时V-PCF，除执行步骤706之外，V-PCF还将转发UE所发送的送达报告至H-PCF，以触发H-PCF保存禁止的APP ID至UDR。
该方法包括以下步骤：
步骤700至步骤703，同图3实施例中的步骤300至步骤303。
步骤704，UE向AMF发送用户策略送达报告，相应地，AMF可以接收到该用户策略送达报告。
该用户策略送达报告携带禁止的APP ID或禁止的PSI。
UE收到PCF所发送的URSP后，可对所收到的URSP进行检查，判断是否需要该URSP。比如，UE检查本地是否有安装该URSP对应的应用，若UE确定没有安装某个URSP对应的应用或者不需要某个URSP对应的应用，则将该应用确定为禁止的APP ID，从而UE可以根据接收到的URSP，得到一个或多个禁止的APP ID。或者，UE检查本地是否有安装该URSP对应的应用，若UE确定没有安装某个URSP对应的应用或者不需要某个URSP对应的应用，则将该URSP确定为禁止的URSP，从而UE可以根据接收到的URSP，得到一个或多个禁止的PSI，其中一个PSI对应一个或多个URSP。
步骤705，AMF向PCF发送用户策略送达报告，相应地，PCF可以接收到该用户策略送达报告。
步骤706，PCF将策略数据保存至UDR。
PCF收到UE所发送的用户策略送达报告后，若其中携带了禁止的PSI，则PCF还需将该禁止的PSI映射为对应的禁止的APP ID。进一步的，还可以根据PCF从UDR中获取的禁止的APP确定最终禁止的APP ID，具体确定方法可以参考图6实施例中的步骤604的相关描述。
当PCF完成URSP决策、或是收到AMF所发送的用户策略关联释放请求消息后，PCF可将本地所决策的最新的URSP及最终的禁止的APP ID保存至UDR。
可选的，还可以在此过程中将OS ID、indication of UE Support for ANDSP等信息存储至UDR。
上述实施例中，提出了一种用户侧辅助PCF执行URSP决策的方案，通过提供本地禁止的应用的标识或禁止的PSI，以避免UE与PCF侧持续更新和维护UE无需使用的URSP所带来的信令开销。
如图8所示，为本申请提供的又一种通信方法流程示意图。该方案为图5A中的情形四的一种具体实现方法。相比图6实施例而言，该实施例中UE所提供的列表为新增的允许的APP ID，而非禁止的APP ID。在该场景下，PCF执行决策时仅需提供该允许的APP ID所对应的URSP。
对于漫游场景，该流程图中PCF可以是V-PCF或是H-PCF，即V-PCF均可根据UE所上报的允许的APP执行URSP决策，并提供更新的URSP至UE；也可以是V-PCF+H-PCF， 即V-PCF在收到UE所发送的UE Policy Container后除执行流程图中所描述的动作外，还可将该UE Policy Container转发至H-PCF，由H-PCF执行流程图中所描述的动作。
该方法包括以下步骤：
步骤801，UE向AMF请求消息。相应地，AMF可以接收到该请求消息。
在一种实现方法中，该请求消息可以是注册请求。比如，该注册请求可以是UE在5G初始注册所对应的注册请求，也可以是UE从4G切换至5G所发起的移动性注册请求(Mobility Registration)。在又一种实现方法中，该请求消息还可以是UE主动发起的策略更新请求。
在该请求消息中，UE携带PSI list(List of stored PSIs)，以告知PCF本地所保存的用户策略列表，以及还携带UE新增的允许的APP ID，该允许的APP可以是新安装的APP。
具体的，请求消息中携带UE Policy Container，该UE Policy Container中包含：List of stored PSIs，允许的APP ID。可选的，该UE Policy Container中还包含OS ID，the indication of UE support for ANDSP。
作为一种实现方式，允许的APP ID可以是以集合或列表的形式携带的。比如，以列表形式携带时，则携带一个allowed list of APP ID。
步骤802，AMF向PCF发送请求消息。相应地，PCF可以接收到请求消息。
若步骤801的请求消息为注册请求，则步骤802的请求消息为策略关联建立请求。若步骤801的请求消息为策略更新请求，则步骤802的请求消息为策略关联更新请求。
该策略关联建立请求中携带上述UE Policy Container，该UE Policy Container中包含PSI list，以及携带允许的APP ID。
步骤803，PCF从UDR中获取策略数据，该策略数据包含UDR中所保存的用户策略信息，该用户策略信息包含URSP。
可选地，该用户策略信息还可以包含UE之前所上报的允许的APP ID。
步骤804，PCF决策生成URSP。
具体的，若PCF确定UE发送的PSI列表对应的URSP与PCF从UDR获取的URSP，则确定需要重新生成URSP。
PCF重新生成URSP的方法包括但不限于以下两种方法：
方法一，PCF根据允许的APP ID(即步骤801携带)，将从UDR中获取的URSP中的与允许的APP ID对应的URSP，确定为重新生成的URSP。
方法二，PCF根据允许的APP ID(即步骤801携带)和从UDR获取的允许的APP ID，得到合并的允许的APP ID，然后将从UDR中获取的URSP中的与合并的允许的APP ID对应的URSP，确定为重新生成的URSP。
步骤805，AMF执行注册流程，并在注册成功后向UE发送响应消息。相应地，UE可以接收到响应消息。
若步骤802的请求消息为策略关联建立请求，则步骤805的响应消息为策略关联建立响应。可选的，该策略关联建立响应可携带PCF向AMF订阅的触发事件列表。
若步骤802的请求消息为策略关联更新请求，则步骤805的响应消息为策略关联更新响应。
步骤806，PCF向AMF发送响应消息。相应地，AMF可以接收到该响应消息。
若步骤801的请求消息为注册请求，则步骤806的响应消息为注册响应。并且步骤806 是在步骤802之前执行。
若步骤801的请求消息为策略更新请求，则步骤806的响应消息为策略关联更新响应。可选的，该策略关联更新响应可以携带上述步骤804中生成的URSP。比如，UE在新增允许的APP ID时，若UE向网络侧提供了APP ID，则PCF在步骤804决策得到该APP ID对应的URSP后，可以直接在该步骤806的响应消息将生成的URSP发送至UE。
步骤807，PCF在UE配置更新流程中将步骤804中生成的URSP发送至UE。
需要说明的是，若上述步骤806已经将步骤804中生成的URSP发送至UE，则该步骤804中不需要携带步骤804中生成的URSP。
步骤808，UE在发起特定业务时根据所收到的URSP执行PDU会话建立/修改流程。
步骤809，当PCF完成URSP决策、或是收到AMF所发送的用户策略关联释放请求消息后，PCF可将本地所决策的最新的URSP及最终的允许的APP ID保存至UDR。
可选的，还可以在此过程中将OS ID、indication of UE Support for ANDSP等信息存储至UDR。
上述实施例中，提出了一种用户侧辅助PCF执行URSP决策的方案，通过提供本地新增的允许的应用的标识，以避免UE与PCF侧持续更新和维护UE无需使用的URSP所带来的信令开销。
