Description

通信方法、装置及系统
本申请要求于2019年04月28日提交中国专利局、申请号为201910351204.2、申请名称为“通信方法、装置及系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及通信技术领域，尤其涉及一种通信方法、装置及系统。
背景技术
目前，通信发展中提出了私网(non-public network，NPN)，私网是相对于公网而言，可以理解为私密的网络，例如公司、学校或者工厂搭建的内部网络。未与私网签约的终端设备不允许接入私网。私网分为两种，一种是非独立私网(Non-Stand-alone Non-Public Network，NSNPN)，用到的网络资源是公网的一部分，NSNPN的公共陆地移动网络标识(Public Land Mobile Networkidentification，PLMN ID)和所依附的公网一致，这类私网被称为封闭接入组(Closed Access Group，CAG)，用CAG ID来标识；另一种是独立私网(Stand-alone Non-Public Network，SNPN)，指的是不依赖公网的网络功能的私网，根据现有的通信协议，SNPN的PLMN ID的移动国家号码(Mobile Contrary Code，MCC)是999，移动网号(Mobile Net Code，MNC)还未定义，用NPN ID来标识。由于私网和公网的业务可以互通，因此可能存在如下类型的业务：公网直接支持的私网业务、私网直接支持的公网业务、公网通过非3GPP互操作功能(non-3GPP interworking function，N3IWF)支持的私网业务、私网通过N3IWF支持的公网业务。
为保障通信服务质量，网络根据基站负载等因素，对终端设备进行接入控制，即用户接入控制(UserAccess Control，UAC)。现有的UAC是基于PLMN ID进行接入控制，也就是网络对不同PLMN ID的终端设备进行不同的接入控制管理，如小运营商A(PLMN 1)租用了大运营商B(PLMN 2)的基站，大运营商就会制定相应的UAC机制，当基站负载较大的时候，会限制小运营商A(PLMN 1)的终端设备接入。因此，现有技术中对公网中的公网业务的终端设备进行接入控制，无法满足存在私网业务时终端设备的接入控制需求。

具体实施方式
图1为本申请实施例提供的通信系统的示意图，如图1所示，通信系统包括网络设备和终端设备，网络设备可以包括无线接入网设备和核心网设备。终端设备通过无线的方式与无线接入网设备相连，无线接入网设备通过无线或有线方式与核心网设备连接。核心网设备与无线接入网设备可以是独立的不同的物理设备，也可以是将核心网设备的功能与无线接入网设备的逻辑功能集成在同一个物理设备上，还可以是一个物理设备上集成了部分核心网设备的功能和部分的无线接入网设备的功能。终端设备可以是固定位置的，也可以是可移动的。图1只是示意图，该通信系统中还可以包括其它网络设备，如还可以包括无线中继设备和无线回传设备，在图1中未画出。本申请的实施例对该通信系统中包括的核心网设备、无线接入网设备和终端设备的数量不做限定。需要说明的是，图1中所示的两个无线接入网设备可以连接到同一核心网设备，也可以连接到不同的核心网设备。
以下，对本申请中的部分用语进行解释说明，以便于本领域技术人员理解：
无线接入网(radio access network，RAN)设备：是一种将终端设备接入到无线网络的设备，可以是长期演进(long term evolution，LTE)中的演进型基站(evolutional Node B，eNB或eNodeB)，或者中继站或接入点，或者5G网络中的基站，如发送和接收点(transmission and reception point，TRP)、控制器，在此并不限定。一种可能的方式中，无线接入网设备可以是集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)分离架构的基站(如gNB)，如图2所示，图2为本申请一实施例提供的无线接入网设备的协议栈示意图。RAN设备可以与核心网设备相连(例 如可以是LTE的核心网，也可以是5G的核心网等)。CU和DU可以理解为是对基站从逻辑功能角度的划分。CU和DU在物理上可以是分离的也可以部署在一起。多个DU可以共用一个CU。一个DU也可以连接多个CU(图中未示出)。CU和DU之间可以通过接口相连，例如可以是F1接口。CU和DU可以根据无线网络的协议层划分。例如无线资源控制(radio resource control，RRC)、业务数据适配协议栈(service data adaptation protocol，SDAP)以及分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能设置在CU，而无线链路控制(radio link control，RLC)，媒体接入控制(media access control，MAC)层，物理(physical，PHY)层等的功能设置在DU。可以理解对CU和DU处理功能按照这种协议层的划分仅仅是一种举例，也可以按照其他的方式进行划分。例如可以将CU或者DU划分为具有更多协议层的功能。例如，CU或DU还可以划分为具有协议层的部分处理功能。在一种设计中，将RLC层的部分功能和RLC层以上的协议层的功能设置在CU，将RLC层的剩余功能和RLC层以下的协议层的功能设置在DU。在另一种设计中，还可以按照业务类型或者其他系统需求对CU或者DU的功能进行划分。例如按时延划分，将处理时间需要满足时延要求的功能设置在DU，不需要满足该时延要求的功能设置在CU。在另一种设计中，CU也可以具有核心网的一个或多个功能。一个或者多个CU可以集中设置，也分离设置。例如CU可以设置在网络侧方便集中管理。DU可以具有多个射频功能，也可以将射频功能拉远设置。
CU的功能可以由一个实体来实现也可以由不同的实体实现。例如，可以对CU的功能进行进一步切分，例如，将控制面(CP)和用户面(UP)分离，即CU的控制面(CU-CP)和CU用户面(CU-UP)。例如，CU-CP和CU-UP可以由不同的功能实体来实现，所述CU-CP和CU-UP可以与DU相耦合，共同完成基站的功能。一种可能的方式中，CU-CP负责控制面功能，主要包含RRC和PDCP-C。PDCP-C主要负责控制面数据的加解密，完整性保护，数据传输等。CU-UP负责用户面功能，主要包含SDAP和PDCP-U。其中SDAP主要负责将核心网的数据进行处理并将数据流(flow)映射到承载。PDCP-U主要负责数据面的加解密，完整性保护，头压缩，序列号维护，数据传输等。其中CU-CP和CU-UP通过E1接口连接。CU-CP代表gNB通过Ng接口和核心网连接。通过F1-C(控制面)和DU连接。CU-UP通过F1-U(用户面)和DU连接。当然还有一种可能的实现是PDCP-C也在CU-UP。
核心网设备：可以是指接入移动管理功能(access and mobility management function，AMF)实体，也可以指会话管理功能(session management function，SMF)实体、移动性管理实体(mobility management entity，MME)或者其它核心网设备。
终端设备：可以是无线终端也可以是有线终端，无线终端可以是指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)中的无线终端等等，在此不作限定。可以理解的是，本申请实施例中，终端设备也可以称为用户设备(user equipment，UE)。
本申请中，“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A,B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a,b,或c中的至少一项(个)，可以表示：a,b,c,a-b,a-c,b-c,或a-b-c，其中a,b,c可以是单个，也可以是多个。
可以理解的，本申请实施例中，终端设备和/或网络设备可以执行本申请实施例中的部分或全部步骤，这些步骤或操作仅是示例，本申请实施例还可以执行其它操作或者各种操作的变形。此外，各个步骤可以按照本申请实施例呈现的不同的顺序来执行，并且有可能并非要执行本申请实施例中的全部操作。
在本申请各实施例中，存在两种网络的概念，一种为公网，另一种为私网。私网一般可以通过私网标识(NPN identification，NPN ID)来识别私网类型，不同的终端设备支持不同的NPN ID，终端设备仅可以在其支持的NPN ID对应的NPN驻留，并仅可以在其签约的NPN ID对应的NPN发起业务。作为一种实现方式，NPN ID也可以是封闭接入组标识(closed access group ID，CAG ID)。
目前，私网的部署方式可以有如下几种：
1、私网可以为配置私网专有的基站、核心网下的小区，支持该私网的终端设备可以在基站、核心网驻留和发起业务，一般称这种私网为独立(standalone，SA)NPN小区。
2、私网也可以为公网的一个切片(slice)，即可以将公网中的一个切片配置为私网，所有终端设备都可以在该网络驻留，等终端设备进入连接态发起业务请求后，网络再根据业务是否是私网业务，把终端设备的业务制定到对应的私网slice上。
3、私网还可以是运营商部署的一个小区。允许该私网下的终端设备的驻留或初始接入。一般称这种私网为封闭访问组(closed access group，CAG)小区，或者非独立(non-standalone，NSA)NPN小区。作为一种可能的实现方式，如图3所示，CAG小区对应的基站可以称为CAG gNB，CAG gNB与公共陆地移动网络(Public Land Mobile Network，PLMN)认证管理功能(authentication management function，AMF)(也可以成为CAG AMF)通信。另外，PLMN AMF还与PLMN gNB，该PLMN gNB可以通过Xn/X2接口与CAG gNB通信。可以理解的，由于方式3中的基站和核心网设备都是运营商部署的，上述CAG gNB是指支持私网的运营商基站，CAG AMF是指支持私网的运营商核心网设备。对于CAG gNB和CAG AMF是否支持公网业务，本申请实施例对此不作限定。
可以理解的，上述方式2和3都是NSA NPN的部署方式。由于方式2和3都是运营商部署的，因此可以支持私网基站和运营商基站间建立X2/Xn连接，和/或私网核心网和公网核心网间建立连接，或者私网核心网和公网核心网为同一核心网。
由于私网的部署，终端设备可以简单地分为三类：
1、私网终端设备：仅与私网签约的终端设备；例如工厂内智能手机的智能终端。
2、同时支持私网和公网的终端设备：比如私网接入人员的手机。
3、公网终端设备：仅与公网签约的终端设备；这种终端设备完全不适用于私网。
对于上述三类终端设备，前两类均可适用于私网，第三类则为完全不适用于私网的终端设备。
在SA NPN和NSA NPN两种私网场景下都考虑了私网和公网的业务互通机制的情况下，公网可以支持私网业务，私网也可以支持公网业务。
以公网支持私网业务的场景为例，存在如下3种业务属性：
1、公网业务
2、和公网属于同一运营商的私网业务，即直接的私网业务
3、公网通过N3IWF支持的私网业务(作为一种可能的实现方式，如图4所示，终端设备为UE，公网中的UE通过N3IWF进行私网业务，即UE与PLMN 3GPP接入(access)连接，PLMN 3GPP接入通过N3与PLMN侧的用户面功能(user plane function，UPF)连接，该UPF与PLMN侧的数据网(data network，DN)连接，以及该UPF通过N4与PLMN侧的SMF连接，该SMF通过N11与PLMN侧的AMF连接，该AMF通过N1与UE连接以及通过N2与PLMN 3GPP接入连接。PLMN侧的DN与NPN侧的N3IWF连接，该N3IWF通过N2与NPN侧的AMF连接以及通过N3与NPN侧的UPF连接，该UPF与NPN侧的DN连接以及通过N4与NPN的SMF连接，该SMF还通过N11与该AMF连接)
以私网支持公网业务的场景为例，存在如下3种业务属性：
1、私网业务
2、和私网属于同一运营商的公网业务，即直接的公网业务
3、私网通过N3IWF支持的公网业务(作为一种可能的实现方式，如图5所示，终端设备为UE示出，私网中的UE通过N3IWF进行私网业务，即UE与NPN 3GPP接入(access)连接，NPN 3GPP接入通过N3与NPN侧的UPF连接，该UPF与NPN侧的DN连接，以及该UPF通过N4与NPN侧的SMF连接，该SMF通过N11与NPN侧的AMF连接，该AMF通过N1与UE连接以及通过N2与PLMN 3GPP接入连接。PLMN侧的DN与PLMN侧的N3IWF连接，该N3IWF通过N2与PLMN侧的AMF连接以及通过N3与PLMN侧的UPF连接，该UPF与PLMN侧的DN连接以及通过N4与PLMN的SMF连接，该SMF还通过N11与该AMF连接)
可选地，公网通过N3IWF支持的私网业务以及私网通过N3IWF支持的公网业务可以属于一种业务属性，该业务属性可称为跨网业务。
因此，在业务存在上述多种业务属性时，本申请各实施例的方案可以更好的针对不同业务对终端设备进行接入控制，具体实现方案如下所述。
图6为本申请一实施例提供的通信方法的流程图，如图6所示，本实施例的方法可以包括：
S601、网络设备生成第一信息。
S602、所述网络设备向终端设备发送所述第一信息。相应地，终端设备接收网络 设备发送的第一信息。
S603、所述终端设备根据当前需发起的第一业务以及所述第一信息，确定所述终端设备是否能发起所述第一业务。
本实施例中，网络设备可以获取N种业务属性的业务的接入控制信息，N为大于等于1的整数，并且该N种业务属性至少包括私网业务。该N种业务属性的业务的接入控制信息例如可以是预先配置在网络设备中，本实施例对此不做限定。网络设备生成第一信息，生成的第一信息中包括该N种业务属性的业务的接入控制信息。然后网络设备向终端设备发送第一信息，相应地，终端设备接收网络设备发送的第一信息。可选地，网络设备可以是向至少一个终端设备广播发送该第一信息，本实施例中提及的终端设备可以是接收网络设备广播发送的第一信息中的任一终端设备。
终端设备接收到第一信息之后，可以根据第一信息获取到N种业务属性的业务的接入控制信息。当终端设备需要发起业务时，该业务可以称为第一业务，第一业务可以为N种业务属性的业务中的任一种业务，终端设备可以根据第一业务以及N种业务属性的业务的接入控制信息，确定第一业务对应的接入控制信息，然后根据该第一业务对应的接入控制信息，确定该终端设备是否能发起该第一业务。例如：终端设备的非接入层(non-access stratum，NAS层)将N种业务属性的业务的接入控制信息发送给终端设备的接入层(access stratum，AS层)，由终端设备的AS层根据当前需发起的第一业务以及N种业务属性的业务的接入控制信息，确定所述终端设备是否能发起所述第一业务。
可选地，该接入控制信息中包括终端设备的接入百分比(uac-BarringFactor)。可选地，该接入控制信息可以包括以下至少一项：终端设备的禁止时间(uac-BarringTime)、终端设备的接入身份标识(uac-BarringForAccessIdentity)。其中，终端设备根据该第一业务对应的接入控制信息，确定该终端设备是否能发起该第一业务的一种可能的实现方式例如可以为：终端设备根据该终端设备生成的随机数与终端设备的接入百分比，确定终端设备是否能发起第一业务，例如随机数小于终端设备的接入百分比，则说明终端设备能发起第一业务，若随机数大于等于终端设备的接入百分比，则说明终端设备不能发起第一业务。若接入控制信息中包括终端设备的禁止时间，则终端设备在确定终端设备不能发起第一业务后，经过该禁止时间之后，再次根据生成的随机数以及接终端设备的接入百分比，确定终端设备是否能发起第一业务。
可选地，上述的私网业务包括如下至少一种：通过私网传输的私网业务、通过公网传输的私网业务。其中，通过公网传输的私网业务可以包括：公网直接支持的私网业务、公网间接支持的私网业务。其中，公网直接支持的私网业务可以是指：在公网中，私网业务通过公网传输到私网的数据网；公网间接支持的私网业务可以是指：通过公网传输私网业务时，私网业务通过公网的用户面传输到私网的N3IWF，由私网的N3IWF传输到私网的数据网。作为一种实现方式如图4所示，一般来说，对于公网间接支持的私网业务，公网不获知该业务是否为私网业务。可选的，上述的私网业务可以包括如下至少一种：私网传输的私网业务、公网直接支持的私网业务、公网间接支持的私网业务。
可选地，所述通过私网传输的私网业务包括通过私网传输的K种接入类别(Access  Category)的私网业务，所述K为大于等于1的整数。下面表一以K等于9为例，如下以0-8分别区分这9种接入类别，但本实施例并不限于此。

本实施例提供的通信方法，通过终端设备接收网络设备发送的第一信息，所述第一信息包括：N种业务属性的业务的接入控制信息，所述N种业务属性至少包括私网业务，然后终端设备根据当前需发起的第一业务以及所述第一信息，确定所述终端设备是否能发起所述第一业务，从而实现存在私网业务时对终端设备的接入控制。
在一些实施例中，所述N种业务属性还可以包括以下至少一项：公网业务、跨网业务。
可选地，上述的公网业务可以包括如下至少一种：通过公网传输的公网业务、通过私网传输的公网业务。其中，通过私网传输的公网业务可以包括：私网直接支持的公网业务、私网间接支持的公网业务。其中，私网直接支持的公网业务可以是指：在私网中，公网业务通过私网传输到公网的数据网；私网间接支持的公网业务可以是指：通过私网传输公网业务时，公网业务通过私网的用户面传输到公网的N3IWF，由公网的N3IWF传输到公网的数据网。作为一种实现方式如图5所示，一般来说，对于私网间接支持的公网业务，私网不获知该业务是否为公网业务。可选的，上述的公网业务可以包括如下至少一种：公网传输的公网业务、私网直接支持的公网业务、私网间接支持的公网业务。
可选地，所述通过公网传输的公网业务包括通过公网传输的M种接入类别的公网业务，所述M为大于等于1的整数。M种接入类别例如可以参见表一中所示，本实施例对此不做限定。
可选地，上述的N种业务属性可以包括私网业务和公网业务，例如：通过私网传输的私网业务、通过公网传输的私网业务、通过公网传输的公网业务、通过私网传输的公网业务。
或者，上述的N种业务属性包括私网业务和跨网业务，例如：通过私网传输的私网业务、跨网业务；或者，通过私网传输的私网业务、通过公网传输的私网业务；或者，通过私网传输的私网业务、通过公网传输的私网业务、通过私网传输的公网业务。
或者，上述的N种业务属性包括私网业务、公网业务和跨网业务，例如：通过私网传输的私网业务、通过公网传输的公网业务、跨网业务。
当终端设备当前接入私网时，该跨网业务表示通过私网传输的公网业务，当终端设备当前接入公网时，该跨网业务表示通过公网传输的私网业务。
在一些实施例中，在第一种可能的实现方式中，上述N种业务属性包括：通过公网传输的公网业务、通过私网传输的公网业务、通过私网传输的私网业务、通过公网传输的私网业务，其中，通过公网传输的公网业务可以包括通过公网传输的9种接入类别的公网业务，例如如表二所示。

如表二所示，数字0-8表示通过公网传输的9种接入类别的公网业务，数字9表示通过公网传输的私网业务，数字10表示通过私网传输的私网业务，数字11表示通过私网传输的公网业务。
在第二种可能的实现方式中，上述N种业务属性包括：通过公网传输的公网业务、通过私网传输的私网业务、跨网业务，其中，通过公网传输的公网业务可以包括通过公网传输的9种接入类别的公网业务，例如如表三所示。
表三

如表三所示，数字0-8表示通过公网传输的9种接入类别的公网业务，数字9表示跨网业务，数字10表示通过私网传输的私网业务。当终端设备当前处于公网时，终端设备可以根据数字9表示通过公网传输的私网业务；当终端设备当前处于私网时，终端设备可以根据数字9表示通过私网传输的公网业务。本实施例通过增加两种业务属性，即可实现对终端设备的公网业务、私网业务、通过公网传输的私网业务、通过私网传输的公网业务的接入控制，从而使得第一信息更简洁。
在第三种可能的实现方式中，上述N种业务属性包括：通过公网传输的公网业务、通过私网传输的公网业务、通过私网传输的私网业务、通过公网传输的私网业务，其中，通过公网传输的公网业务可以包括通过公网传输的9种接入类别的公网业务，通过私网传输的私网业务可以包括通过私网传输的9种接入类别的私网业务，例如如表四所示。

如表四所示，数字0-8表示通过公网传输的9种接入类别的公网业务，数字9表示通过公网传输的私网业务，数字10-18表示通过私网传输的9种接入类别的私网业务，数字19表示通过私网传输的公网业务。当终端设备当前处于公网时，终端设备可以根据数字9表示通过公网传输的私网业务；当终端设备当前处于私网时，终端设备可以根据数字19表示通过私网传输的公网业务。因此，本实施例可以对私网业务中不 同的接入类别进行接入控制，提高了接入控制的灵活性。
在一些实施例中，所述第一信息包括R个PLMN中每个PLMN所对应的N种业务属性的业务的接入控制信息，所述R为大于等于1的整数。相应地，上述S603的一种可能的实现方式为：所述终端设备根据当前需发起的第一业务、所述终端设备的RPLMN以及所述第一信息，确定所述终端设备是否能发起所述第一业务。其中，终端设备的RPLMN为上述R个PLMN中的任一个PLMN。

S701、网络设备生成第一信息。
S702、所述网络设备向终端设备发送所述第一信息。相应地，终端设备接收网络设备发送的第一信息。
S703、所述终端设备根据当前需发起的第一业务、所述终端设备的RPLMN以及所述第一信息，确定所述终端设备是否能发起所述第一业务，和/或，所述终端设备根据当前需发起的第一业务、所述终端设备当前接入的私网以及所述第一信息，确定所 述终端设备是否能发起所述第一业务。
本实施例中，所述第一信息包括：R个PLMN中每个PLMN所对应的N种业务属性的业务的接入控制信息，以及H个私网中每个私网所对应的N种业务属性的业务的接入控制信息，所述R、H为大于等于1的整数。终端设备接收第一信息之后，根据当前需发起的第一业务、所述终端设备的RPLMN以及所述第一信息，确定所述终端设备是否能发起所述第一业务，和/或，所述终端设备根据当前需发起的第一业务、所述终端设备当前接入的私网以及所述第一信息，确定所述终端设备是否能发起所述第一业务。
本实施例中，若终端设备当前接入公网，表示终端设备只存在终端设备的RPLMN，则终端设备可以根据当前需发起的第一业务、终端的RPLMN以及所述第一信息，确定终端设备是否能发起第一业务。
若终端设备当前接入私网，表示同时存在终端设备的RPLMN以及终端设备当前接入的私网，其中，RPLMN可以由对应的PLMN ID来表示，当前接入的私网可以由私网的标识来表示，例如：CAG ID或NPN ID。在一种实现方式中，终端设备可以根据当前需发起的第一业务、终端设备的RPLMN以及所述第一信息，确定终端设备是否能发起第一业务。若根据终端设备的RPLMN确定终端设备不能发起第一业务，则终端设备不能发起第一业务。若根据终端设备的RPLMN确定终端设备能发起第一业务，则终端设备再根据当前需发起的第一业务、终端设备当前接入的私网以及所述第一信息，确定终端设备能否发起第一业务，若根据终端设备当前接入的私网确定终端设备能发起第一业务，则终端设备能发起第一业务，若根据终端设备当前接入的私网确定终端设备不能发起第一业务，则终端设备不能发起第一业务。在另一种实现方式中，终端设备可以根据当前需发起的第一业务、终端设备当前接入的私网以及所述第一信息，确定终端设备是否能发起第一业务。若根据终端设备当前接入的私网确定终端设备不能发起第一业务，则终端设备不能发起第一业务。若根据终端设备当前接入的私网确定终端设备能发起第一业务，则终端设备再根据当前需发起的第一业务、终端设备的RPLMN以及所述第一信息，确定终端设备能否发起第一业务，若根据终端设备的RPLMN确定终端设备能发起第一业务，则终端设备能发起第一业务，若根据终端设备的RPLMN确定终端设备不能发起第一业务，则终端设备不能发起第一业务。
总之，终端设备当前接入私网，若终端设备根据当前需发起的第一业务、终端设备的RPLMN以及所述第一信息，确定终端设备能发起第一业务，并且根据当前需发起的第一业务、终端设备当前接入的私网以及所述第一信息，确定终端设备能发起第一业务，则最终确定终端设备能发起第一业务，否则最终确定终端设备不能发起第一业务。
如果终端设备根据当前需发起的第一业务、终端设备的RPLMN以及所述第一信息，确定终端设备不能发起第一业务，并且根据当前需发起的第一业务、终端设备当前接入的私网以及所述第一信息，确定终端设备也不能发起第一业务，则终端设备的禁止时间为第一禁止时间与第二禁止时间中的最大值，第一禁止时间为终端设备的RPLMN对应的第一业务的接入控制信息中的禁止时间，第二禁止时间为终端设备当前接入的私网对应的第一业务的接入控制信息中的禁止时间。
本实施例中的第一信息可以包括如下所述：
Figure PCTCN2020084737-appb-000006
其中，每个PLMN由PLMN ID index来标识，每个PLMN下配置有N种业务属性的业务，可以通过AccessCategory来区分不同的业务属性，其中，每个AccessCategory与uac-barringInfoSetIndex对应，然后从UAC-BarringInfoSetList中可以获取与uac-barringInfoSetIndex对应的接入百分比、禁止时间、接入身份等信息，这些信息可以称为接入控制信息。并且每个私网由CAGorNPNID index来标识，每个私网下配置有N种业务属性的业务，可以通过AccessCategory来区分不同的业务属性，其中，每个AccessCategory与uac-barringInfoSetIndex对应，然后从UAC-BarringInfoSetList中可以获取与uac-barringInfoSetIndex对应的接入百分比、禁止时间、接入身份等信息，这些信息可以称为接入控制信息。
因此，通过上述方案，可以实现存在私网业务时对终端设备的接入控制。
图8为本申请另一实施例提供的通信方法的流程图，如图8所示，本实施例的方法可以包括：
S801、网络设备生成第一信息。
S802、所述网络设备向终端设备发送所述第一信息。相应地，终端设备接收网络设备发送的第一信息。
S803、所述终端设备根据当前需发起的第一业务、所述终端设备的RPLMN、所述终端设备当前接入的私网以及所述第一信息，确定所述终端设备是否能发起所述第一业务。
本实施例中，所述第一信息包括：R个PLMN中每个PLMN与H个私网中每个私网两者对应的N种业务属性的业务的接入控制信息，所述R、H为大于等于1的整数。同一个PLMN下，不同的私网可以对应不同的接入控制信息。终端设备接收第一信息之后，根据当前需发起的第一业务、所述终端设备的RPLMN、所述终端设备当前接入的私网以及所述第一信息，确定所述终端设备是否能发起所述第一业务。
其中，PLMN可以通过PLMN ID来标识，私网可以通过私网的标识(例如CAG ID或NPN ID)来标识。若PLMN ID表示公网，且不存在CAG ID，则说明终端设备接入的网络是公网。若PLMN ID表示公网，同时存在CAG ID，则说明终端设备接入的网络是非独立私网。若PLMN ID表示私网，且同时存在NPN ID，则说明终端设备接入的网络是独立私网。
本实施例中，若终端设备当前接入私网，表示同时存在终端设备的RPLMN以及终端设备当前接入的私网，其中，RPLMN可以由对应的PLMN ID来表示，当前接入的私网可以由私网的标识来表示，例如：CAG ID或NPN ID。在一种实现方式中，终端设备可以根据终端设备的RPLMN，从R个PLMN中获取该RPLMN与H个私网分别对应的N种业务属性的业务的接入控制信息，然后根据终端设备当前接入的私网，从该RPLMN与H个私网分别对应的N种业务属性的业务的接入控制信息中，确定该终端设备当前接入的私网对应的N种业务属性的业务的接入控制信息。然后终端设备根据上述确定的N种业务属性的业务的接入控制信息以及第一业务，确定终端设备是否能接入第一业务。
本实施例中的第一信息可以包括如下所述：
Figure PCTCN2020084737-appb-000007
需要说明的是，若终端设备当前接入公网，表示终端设备只存在终端设备的RPLMN，因此，针对属于公网的PLMN，本实施例中可以不配置这类PLMN与私网两者对应的业务属性的业务的接入控制信息，即上述第一信息中可以不包括这类PLMN对应的业务属性的业务的接入控制信息，网络设备可以向终端设备发送其它信 息，该其它信息中包括多个公网的PLMN中每个PLMN对应的N种业务属性的业务的接入控制信息。
因此，通过上述方案，可以实现存在私网业务时对终端设备的接入控制。
在一些实施例中，在S603或S703或S803之前，终端设备还接收所述网络设备发送的第二信息，所述第二信息用于指示所述N种业务属性的业务是否被所述网络设备支持。相应地，在所述第二信息指示所述第一业务被所述网络设备支持时，所述终端设备执行S603或S703或S803。
本实施例中，网络设备向终端设备发送第二信息，该第二信息用于指示上述的N种业务属性的业务是否被所述网络设备支持，例如第二信息可以指示网络设备支持上述N种业务属性的业务中的哪些业务，也可以指示网络设备不支持上述N种业务属性的业务中的哪些业务。相应地，终端设备接收网络设备发送的第二信息，在终端设备接收第一信息以及接收第二信息之后，当终端设备当前需发起第一业务时，终端设备根据第二信息，确定第一业务被网络设备支持时，终端设备执行S603或S703或S803。可选地，当终端设备根据第二信息，确定第一业务不被网络设备支持时，所述终端设备确定所述终端设备不能发起所述第一业务。
在一种可能的实现方式中，第二信息与第一信息为不同的信息，第二信息中例如可以通过0或1来显示表示网络设备是否支持上述N种业务属性的业务。网络设备可以将第二信息包括在系统消息中发送给终端设备。第二信息与第一信息可以包括在网络设备向终端设备发送的同一消息中，也可以分别包括在网络设备向终端设备发送的不同消息中。
在另一种可能的实现方式中，第二信息与第一信息为相同信息，其中，第一信息中的接入百分比用于表示网络设备是否支持上述N种业务属性的业务，若某种业务属性的业务对应的接入百分比为0，则说明网络设备不支持该种业务属性的业务，若某种业务属性的业务对应的接入百分比不为0，则说明网络设备支持该种业务属性的业务。
可以理解的是，上述各个实施例中，由网络设备实现的操作和步骤也可以由可用于网络设备的部件(例如芯片或者电路)实现，本申请实施例对此不作限定。
