Description

一种接入网络的方法及通信装置
本申请要求于2019年11月12日提交中国国家知识产权局、申请号为201911102862.4、发明名称为“一种接入网络的方法及通信装置”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
本申请涉及通信领域，尤其是一种接入网络的方法及通信装置。
背景技术
随着第五代移动通信系统(5th generation wireless systems，5G)的快速发展，终端设备的类型也在不断增多，除了常见的手机(mobile phone)、平板电脑之外，终端设备还可以包括物联网(internet of things，IOT)设备、家庭宽带接入的家庭网关设备等。
一般情况下，每个终端设备均是依据其对应的签约信息进行网络接入的。其中，签约信息是由运营商配置的，记录了包括标识允许终端设备接入网络的位置的签约位置信息在内等信息。也就是说，每个终端设备只有在其对应的签约位置信息允许的位置才能够接入到网络，否则，将出现网络接入失败的情况。例如，当终端设备需要在某个位置接入网络时，若该终端设备对应的签约位置信息中允许其接入网络的位置区域包含该位置，则表明该终端设备可以在该位置接入网络，若该终端设备对应的签约位置信息中允许其接入网络的位置区域不包含该位置，则表明该终端设备无法在该位置接入网络。
因此，当终端设备所在位置发生变化，导致其所在位置不在签约位置信息中允许接入网络的位置区域时，会出现终端设备接入网络失败的情况。所以，如何在终端设备位置发生变化时，提高终端设备网络接入的准确性是目前需要解决的技术问题。

具体实施方式
下面结合附图，对本申请的实施例进行描述。
参见图1a，其示出了本申请实施例应用的一种系统架构的示例图，如图1a所示，该场景中，包括了终端设备101、5G核心网102和网元A103。终端设备101与5G核心网102连接，5G核心网102和网元A103连接。上述“连接”可以是直接连接，也可以是间接连接。
其中，终端设备101又可以称为用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)、终端等，是一种向用户提供语音和/或数据连通性的设备，或，设置于该设备内的芯片，例如，具有无线连接功能的手持式设备、车载设备等。目前，一些终端设备的举例为：手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)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、支持5G接入的家庭网关设备(5G-residential gateway，5G-RG)等。本申请实施例提供的终端设备可以是低复杂度终端设备和/或处于覆盖增强A模式下的终端设备。
5G核心网102给出了5G核心网中的部分功能网元，包括接入与移动性管理功能AMF网元、会话管理功能(session management function，SMF)网元、统一数据管理(unified data management，UDM)网元、用户面功能(user plane function，UPF)网元、网络能力开放功能(network exposure function，NEF)网元、策略控制功能(policy control function，PCF)网元。当然，核心网中还可以包括其他功能网元，具体可以参考5G标准相关描述。
AMF网元是由运营商网络提供的控制面网元，主要负责终端设备接入运营商网络的接入控制和移动性管理，例如包括移动状态管理，分配用户临时身份标识，认证和授权用户等功能。
SMF网元是由运营商网络提供的控制面网元，负责管理终端设备的协议数据单元(protocol data unit，PDU)会话。PDU会话是一个用于传输PDU的通道，终端设备101需要通过PDU会话与数据网络(data network，DN)互相传送PDU。PDU会话由SMF网元负责建立、维护和删除等。SMF网元包括会话管理(如会话建立、修改和释放，包含UPF网元和无线接入网(radio access network，RAN)之间的隧道维护)、UPF网元的选择和控制、业务和会话连续性(Service and Session Continuity，SSC)模式选择、漫游等会话相关的功能。
UPF网元是由运营商提供的网关，是运营商网络与DN通信的网关。UPF网元包括数据 包路由和传输、包检测、业务用量上报、服务质量(Quality of Service,QoS)处理、合法监听、上行包检测、下行数据包存储等用户面相关的功能。
PCF网元是由运营商提供的控制面功能，用于向SMF网元提供PDU会话的策略。策略可以包括计费相关策略、QoS相关策略和授权相关策略等。
UDM网元负责管理终端设备101的签约信息，当签约信息修改的时候，负责通知相应的网元。
NEF网元主要支持网络能力开放功能，对外开放网络能力和服务，3GPP网络功能(Network Function，NF)通过NEF向其他NF发布功能和事件。NF开放的能力和事件可以安全地开放给第三方应用。NEF使用统一数据存储库(unified data repository，UDR)的标准化接口(Nudr)将结构化数据进行存储/检索。将AF的交换信息与内部网络功能的交换信息进行翻译。例如它将在AF服务标识AF-Service-Identifier和内部5G核心信息之间进行转换。
网元A103可以是一种应用功能(application function，AF)网元，如数据网络名称(Data Network Name，DNN)对应的网络中的应用功能网元或应用功能服务器，用于向终端设备101提供某种应用层服务，AF在向终端设备101提供服务时，对服务质量QoS策略(Policy)和计费策略(Charging)有要求，且需要通知网络。同时，AF也需要核心网反馈的应用相关的信息。或者，网元A103也可以是一种新增的、独立的5G功能网元，与5G核心网中其他网元直接进行交互，用以为终端设备101提供相应的服务。
或者，在另一场景中，如图1b所示，终端设备101为5G-RG，图1b示出了该5G-RG通过固定网络接入5G核心网102的场景示意图。其中，固定网络可以包括有线有源网络(wireline active network)、接入网关功能(fixed access gateway function，FAGF)等。5G核心网102如图1b上半部分所示，该5G核心网不仅包括上述场景介绍的AMF网元、SMF网元、NEF网元、PCF网元以及UDM网元，还包括了认证服务(authentication server function，AUSF)网元、网络切片选择功能(network slice selection function，NSSF)网元以及网元数据仓库功能(nf repository function，NRF)网元等，各个网元的具体功能介绍可以参考5G标准相关描述。
或者，在另一场景中，如图1c所示，终端设备101仍为5G-RG，图1c示出了该5G-RG通过3GPP无线网络(NG RAN)接入5G核心网102的场景示意图。其中，3GPP无线网络可以包括下一代3GPP无线接入网，或者5G 3GPP接入网等。具体功能介绍可以参考5G标准相关描述。
本申请中，第一网元可以为图1a所示的5G核心网102中的AMF网元或UDM网元，第一终端设备可以为图1所示的终端设备101，这样，在实现终端设备101与网元A103之间的网络交互的过程中，首先可以由AMF网元或UDM网元获取到包括终端设备101的接入位置信息的接入请求以及包括第一终端设备的签约位置信息的签约信息，然后判断该接入位置信息是否属于签约位置信息，当判断出该接入位置信息不属于签约位置信息时，AMF网元或UDM网元可以根据获取到的允许信息，允许终端设备101在该接入位置信息对应的接入位置接入网络，进而实现与网元A103之间的网络交互，从而在无需联系运营商进行签约 信息更新的情况下，通过AMF网元或UDM网元对终端设备101的接入位置信息的判断，并结合获取到的允许信息，使得该接入位置信息成为新的签约位置信息，从而实现了签约信息的自动更新，无需消耗较长的更新时间，提高了终端设备接入网络的准确性。
需要注意的是，上述几种应用场景仅是为了便于理解本申请而示出，本申请的实施方式在此方面不受任何限制。相反，本申请的实施方式可以应用于适用的任何场景，例如，后续演进的通信系统。
基于以上应用场景，本申请实施例提供了一种接入网络方法，下面对该方法进行介绍。
S201：第一网元获取接入请求，其中，接入请求包括第一终端设备的接入位置信息。
在本实施例中，将采用本实施例接入网络的任一终端设备定义为第一终端设备，可以理解的是，第一终端设备可以是上述终端设备101中提及的任意一种终端设备。实现第一终端设备接入网络指的是第一终端设备通过接入图1所示的5G核心网502来获取各种服务的过程，比如，可以通过接入图1所示的5G核心网502，与网元A103进行数据交互，以实现网络注册、在线开户等签约信息的更新，以使得第一终端设备可以在当前所在接入位置接入网络。
在实现第一终端设备的网络接入时，首先需要由第一网元通过接入网(如5G基站、非3GPP接入网关等)获取到包括第一终端设备的接入位置信息的接入请求，其中，第一网元可以是上述介绍的5G核心网102中的AMF网元或UDM网元，也可以是MME网元。第一终端设备的接入位置信息可以包括蜂窝位置信息，如cell ID，或无线局域网(wireless local area networks，WLAN)接入点信息，如服务集标识(service set identifier，SSID)，或固定接入点位置信息，如线路标识line ID等。
需要说明的是，本申请实施例对接入网络的网络类型、第一终端设备的接入位置信息的类型均不做限制，可根据实际情况进行选择。本申请实施例后续将以固定接入网络以及line ID作为第一终端设备的接入位置信息为例进行说明。
S202：第一网元获取第一终端设备的签约信息，其中，签约信息包括签约位置信息。
在本实施例中，为了提高第一终端设备接入网络的准确性，第一网元还需要根据第一终端设备的标识来获取第一终端设备的签约信息，其中，签约信息包括签约位置信息，签约位置信息指的是记录的第一终端设备能够接入网络的位置区域对应的信息。第一终端设备的标识指的是表征第一终端设备身份信息的用户标识，可以包括用户隐藏标识符(subscription concealed identifier，SUCI)、全球唯一永久标识符(subscription permanent identifier，SUPI)、第一终端的电话号码(the mobile station integrated services digital network number，MSISDN)、临时标识等的至少一个。
S203：当第一网元确认第一终端设备的接入位置信息不属于签约位置信息时，第一网元获取允许信息，其中，允许信息为允许第一终端设备在接入位置信息对应的接入位置接入网络的信息。
在本实施例中，第一网元在获取到包括第一终端设备的接入位置信息的接入请求以及包含第一终端设备签约位置信息的签约信息后，第一网元进一步还需要判断出第一终端设备的接入位置信息是否属于签约位置信息，即，需要判断出该接入位置信息是否属于第一 终端设备的对应的签约信息记录的第一终端设备接入网络的位置区域。
当第一网元确认第一终端设备的接入位置信息不属于签约位置信息时，即，该接入位置信息不属于第一终端设备的对应的签约信息记录的第一终端设备接入网络的位置区域，此时，第一网元可以获取允许信息，该允许信息指的是允许第一终端设备在接入位置信息对应的接入位置接入网络的信息，该允许消息可以是签约信息中的第一参数，该第一参数指示第一终端设备可以在非签约的接入位置接入网络，上述第一参数可以是指示信息、第一终端设备的标识和/或第一终端设备的类型；和/或，该允许消息也可以是通过第一终端设备或第二终端设备确认的第一终端设备可以在接入位置信息对应的接入位置接入网络的信息。其中，第二终端设备指的是除了第一终端设备外的其他终端设备，该第二终端设备的标识可以是与第一终端设备的标识具有特定的映射关系，该映射关系体现了第一终端设备的标识与第二终端设备的标识之间一一对应的关系，利用该映射关系，可以根据其中任意一个终端设备的标识，确定出另一个对应的终端设备的标识。这样，当无法通过第一终端设备来确认其可以在接入位置信息对应的接入位置接入网络时，可以利用第二终端设备来进行确认。或者，第二终端设备也可以是用户通过其登录社交软件(如邮箱、微信等)的账户的终端设备。
需要说明的是，当第一网元为接入管理网元(AMF网元或MME网元)或UDM网元时，根据第一网元获取允许消息的不同途径，可以对应产生四种不同的触发网络接入的实现方式，通过每种实现方式均可判断出第一终端设备的接入位置信息是否属于签约位置信息以及后续第一网元如何获取允许消息，以允许第一终端设备在接入位置信息对应接入位置接入网络，具体实现过程可参见后续实施例的详细介绍。
S204：第一网元根据允许信息允许第一终端设备在接入位置信息对应的接入位置接入网络。
在本实施例中，当第一网元获取到允许第一终端设备在接入位置信息对应的接入位置接入网络的允许信息后，即可根据该允许消息允许第一终端设备在接入位置信息对应的接入位置接入网络，即，实现了第一终端设备的对应的签约信息的自动更新。
并且，一种可选的实现方式是，第一网元还可以向第一终端设备发送接入成功消息。以便于第一终端设备可以根据该消息，在接入位置信息对应的接入位置随时接入网络，无需再通过联系运营商为其重新配置新的签约信息以实现网络接入，提高了其接入网络的准确性。
综上，本实施例提供的一种接入网络方法，在实现第一终端设备的网络接入时，第一网元先获取到包括第一终端设备的接入位置信息的接入请求，其中，第一网元可以是接入管理网元或UDM网元，接入管理网元可以是AMF网元或MME网元。然后，第一网元可以获取包括第一终端设备的签约位置信息的签约信息，接着，当第一网元确认出第一终端设备的接入位置信息不属于签约位置信息时，第一网元可以获取允许第一终端设备在接入位置信息对应的接入位置接入网络的允许信息，进而，可以根据该允许消息允许第一终端设备在接入位置信息对应的接入位置接入网络。可见，相比较于目前通过联系运营商为终端设备重新配置新的签约信息以实现网络接入的方法而言，本申请实施例是利用第一网元先对 第一终端设备的接入位置信息是否属于签约位置信息进行判断，并在判断出该接入位置信息不属于签约位置信息情况下，根据获取到的允许信息，允许第一终端设备在接入位置信息对应的接入位置接入网络，无需消耗较长的时间，提高了终端设备接入网络的准确性。
接下来，本实施例将对当第一网元为接入管理网元(AMF网元或MME网元)或UDM网元时，产生的四种不同的实现方式的具体实现过程进行介绍。
(1)在本实施例的第一种实现方式中，第一网元例如为AMF网元，第二网元为网元A(如AF网元，即DNN网络中与终端交互的应用功能网元，或DNN网络中的应用服务器，或5G核心网络中的逻辑功能网元A)，如图3所示，具体实现过程可以包括下述步骤A1-A6：
步骤A1：AMF网元接收第一终端设备发送的接入请求，该接入请求中包括第一终端设备的标识。
其中，第一终端设备的标识指的是表征第一终端设备身份信息的用户标识，可以包括SUCI、SUPI、MSISDN、临时标识中的至少一个。并且，第一终端设备在通过接入网将接入请求发送至AMF网元的过程中，接入网会将第一终端设备的接入位置信息插入到该接入请求中或者会将第一终端设备的接入位置信息与接入请求一并发送给AMF网元，以便AMF网元接收到第一终端设备的接入位置信息和标识。
步骤A2：AMF网元向UDM网元发送签约信息获取请求，该签约信息获取请求包括第一终端设备的标识。
AMF网元将包含第一终端设备标识的签约信息获取请求发送至UDM网元后，UDM网元可以根据该标识获取到第一终端设备对应的签约信息，该签约信息中记录了允许第一终端设备接入网络的位置区域(即签约位置信息)。
步骤A3：AMF网元接收UDM网元根据第一终端设备的标识发送的签约信息。
步骤A4：AMF网元判断签约信息中的签约位置信息是否包括接入位置信息。
AMF网元在接收到UDM网元发送的第一终端设备对应的签约信息后，进一步可以判断出该签约信息中是否记录有通过步骤A1中接收到的第一终端设备的接入位置信息，若是，则表明可以在该接入位置信息实现第一终端设备的网络接入；若否，这表明该接入位置信息并非属于签约位置信息，需要继续执行后续步骤A5。
举例说明：假设第一终端设备对应的签约信息中记录了允许第一终端设备进行网络注册的位置区信息，如允许网络接入的line ID列表，或不允许网络接入的line ID列表(意味着可以从非此列表的位置区接入)等，进而可以通过判断第一终端设备的接入位置信息对应的line ID是否属于签约信息中记录的允许网络接入的line ID列表或不允许网络接入的line ID列表，得到第一终端设备的接入位置信息对应的line ID是否为合法的接入位置信息的判断结果。
步骤A5：AMF网元判断签约信息中是否包括第一参数，若是，则进一步基于签约信息中的第一参数判断第一终端设备是否可以在接入位置信息对应的接入位置接入网络，上述第一参数包括指示信息、第一终端设备的标识和/或第一终端设备的类型。
如通过步骤A4判断出签约信息中的签约位置信息并未包括接入位置信息，即该接入位 置信息并非属于签约位置信息，则AMF网元进一步还需要判断出该签约信息中是否包括第一参数(用于指示当第一终端设备的接入位置信息不属于签约位置信息时，允许第一终端设备在接入位置信息对应的接入位置接入网络)，当判断出签约信息中包括该第一参数时，AMF网元即可允许第一终端设备在接入位置信息对应的接入位置接入网络。或者，AMF网元可以基于第一终端设备的标识或第一终端设备的类型允许第一终端设备在非签约的接入位置接入网络。例如，可以通过第一终端设备的标识或第一终端设备的类型识别出第一终端设备为特殊的终端设备，并对上述特殊的终端设备允许其在非签约的接入位置接入网络。
步骤A6：AMF网元向网元A发送第一指示信息、终端设备的信息以及终端设备对应的接入管理单元的标识中的至少一个。
其中，如上述对网元A103的介绍，网元A指的是可以为移动终端提供服务的一种应用功能网元。
当通过步骤A5判断出签约信息中不包括第一参数时，则AMF网元可以向网元A发送第一指示信息、终端设备的信息、第一终端设备的接入位置信息以及终端设备对应的接入管理网元的标识中的至少一个，用以获取自网元A的允许消息。并且，当仅发送第一终端设备的接入位置信息时，可以通过将该信息携带在一个新增的字段中来指示第二网元获取允许信息。
其中，第一指示信息用于指示网元A获取允许信息，第一指示信息是参数信息或者消息类型。终端设备的信息指的是第一终端设备的标识或者第二终端设备的标识，其中，第二终端设备的标识指的是表征第二终端设备身份信息的用户标识，可以包括SUCI、SUPI、MSISDN、临时标识中的至少一个。第二终端设备指的是除了第一终端设备外的其他终端设备，且第二终端设备的标识可以是与第一终端设备的标识具有特定的映射关系，或者，第二终端设备也可以是用户通过其登录社交软件(如邮箱、微信等)的账户的终端设备。
进一步的，第二网元可以根据终端设备的信息以及终端设备对应的AMF网元，从终端设备获取允许消息，具体实现过程可参见后续实施例的详细介绍。
(2)在本实施例的第一种实现方式中，第一网元例如为UDM网元，第二网元仍为网元A，如图4所示，具体实现过程可以包括下述步骤B1-B7：

步骤B2：AMF网元向UDM网元发送签约信息获取请求，该签约信息获取请求包括第一终端设备的标识。
步骤B3：AMF网元接收UDM网元根据第一终端设备的标识发送的签约信息。
步骤B4：AMF网元判断签约信息中的签约位置信息是否包括接入位置信息。
需要说明的是，步骤B1-B4与上述步骤A1-A4一致，相关之处请参见步骤A1-A4的介绍，在此不再赘述。
步骤B5：AMF网元向UDM网元发送指示信息。
其中，指示信息用于指示第一终端设备的接入位置信息并非属于签约位置信息。
步骤B6：UDM网元判断签约信息中是否包括第一参数，若是，则进一步基于签约信息中的第一参数判断第一终端设备是否可以在接入位置信息对应的接入位置接入网络，上述第一参数包括指示信息、第一终端设备的标识和/或第一终端设备的类型。
UDM网元在判断出接收到AMF网元发送的第一终端设备的接入位置信息并非属于签约位置信息的指示信息后，进一步还需要判断出签约信息中是否包括第一参数，当判断出签约信息中包括第一参数时，UDM网元即可根据第一终端设备的接入位置信息允许第一终端设备在接入位置信息对应的接入位置接入网络。或者，UDM网元可以基于第一终端设备的标识或第一终端设备的类型允许第一终端设备在非签约的接入位置接入网络。
步骤B7：UDM网元向网元A发送第一指示信息、终端设备的信息以及终端设备对应的接入管理单元的标识中的至少一个。
步骤B7与步骤A6基本相同，只是步骤的执行主体不同。步骤A6中步骤的执行主体为AMF网元，而步骤B7中步骤的执行主体为UDM网元。所以，此处不再对步骤B7进行赘述，相关内容请参见步骤A6。
(3)在本实施例的第一种实现方式中，第一网元例如为UDM网元，第二网元仍为网元A，如图5所示，具体实现过程可以包括下述步骤C1-C6：
步骤C1：AMF网元接收第一终端设备发送的接入请求，该接入请求中包括第一终端设备的标识。
步骤C2：AMF网元向UDM网元发送接入请求，该接入请求中包括第一终端设备的接入位置信息和标识。
步骤C3：UDM网元根据第一终端设备的标识获取第一终端设备对应的签约信息，该签约信息中记录了允许第一终端设备接入网络的位置区域(即签约位置信息)。
步骤C4：UDM网元判断签约信息中的签约位置信息是否包括接入位置信息。
UDM网元判断该签约信息中的签约位置信息是否记录有第一终端设备的接入位置信息，若是，则表明可以在该接入位置信息实现第一终端设备的网络接入；若否，这表明该接入位置信息并非属于签约位置信息，需要继续执行后续步骤C5。
步骤C5：UDM网元判断签约信息中是否包括第一参数，若是，则进一步基于签约信息中的第一参数判断第一终端设备是否可以在接入位置信息对应的接入位置接入网络，上述第一参数包括指示信息、第一终端设备的标识和/或第一终端设备的类型。
UDM网元在确认出第一终端设备的接入位置信息并非属于签约位置信息后，进一步还需要判断出签约信息中是否包括第一参数，当判断出签约信息中包括第一参数时，UDM网元即可允许第一终端设备在接入位置信息对应的接入位置接入网络。或者，UDM网元可以基于第一终端设备的标识或第一终端设备的类型允许第一终端设备在非签约的接入位置接入网络。
步骤C6：UDM网元向网元A发送第一指示信息、终端设备的信息以及终端设备对应的接入管理单元的标识中的至少一个。
需要说明的是，步骤C6与上述步骤B7一致，相关之处请参见步骤B7的介绍，在此不 再赘述。
(4)在本实施例的第一种实现方式中，如图6所示，具体实现过程可以包括下述步骤D1-D3：
步骤D1：第一终端设备接收第一网元(AMF网元或UDM网元)发送的第二指示信息。
其中，第二指示信息可以包括第二网元的标识(可以是第二网元的互联网协议(internet protocol，IP)地址和所属网元的网络名称中的一项或多项)和/或用于指示第一终端设备处于接入受限状态的信息(即第一终端设备在接入位置信息对应的接入位置属于非签约位置，无法正常接入网络的信息)。且该指示信息也指示了第一终端设备需要建立用于与第二网元(即网元A)进行通信的会话，用以实现后续的网络接入功能。即，第二指示信息用于指示第一终端设备建立到网元A的PDU会话，以便第一终端设备可以通过该PDU会话与网元A互相传送会话数据。
接下来，如图7所示，本申请实施例将通过下述步骤E1-E5，对第一终端设备建立PDU会话的具体实现过程进行介绍：
步骤E1：第一网元(如AMF网元)向PCF网元(和/或SMF)发送用于指示第一终端设备处于接入受限状态的信息和第一终端设备标识。
其中，PCF网元在接受到指示第一终端设备处于接入受限状态的信息和第一终端设备标识后，进一步可以向与第一终端设备的标识对应的第一终端设备发送网元A相关的网络参数，该网络参数用于建立第一终端设备到网元A的PDU会话。
步骤E2：PCF网元向第一终端设备发送网元A相关的网络参数。
其中，网元A相关的网络参数可以包括网元A所在网络的数据网络名称(data network name,DNN)和网元A的IP地址或全限定域名(fully qualified domain name,FQDN)中的一项或多项内容，另外，为了建立第一终端设备到网元A的PDU会话，网元A相关的网络参数还可以包括需要建立的PDU会话的会话类型。
步骤E3：第一终端设备向SMF网元发送PDU会话建立请求。
其中，PDU会话建立请求用于指示SMF网元为第一终端设备建立到网元A的PDU会话。
具体来讲，第一终端设备可以发送非接入层(non-access stratum，NAS)传输消息给AMF网元，其中包含有PDU会话建立请求消息。且该NAS传输消息或/和PDU会话建立请求消息中包含有网元A相关的网络参数。
其中，网元A相关的网络参数用于指示SMF网元为第一终端设备建立到网元A的PDU会话。
步骤E4：AMF网元将接收到的PDU会话建立请求转发至SMF网元。
或者，也可以通过AMF网元将PDU会话建立请求以及第一终端设备的接入位置信息发送至SMF网元，以便SMF网元执行步骤E5。
步骤E5：SMF网元为第一终端设备建立到网元A的PDU会话。
具体来讲，SMF网元可以向UPF网元发送会话建立请求消息，该请求消息中包括会话标识、在线开户指示，以指示UPF将PDU会话的所有数据包(报文)路由到网元A，以建立第一终端设备与网元A之间的PDU会话。在本申请实施例中，在线开户是指当第一终端 设备处于接入受限状态时，执行的允许第一终端设备接入网络的流程。在线开户指示是用于指示对第一终端设备执行在线开户流程的指示，或用于指示第一终端当前处于接入受限状态，执行在接入受限状态时的流程。上述在线开户流程或接入受限状态时的流程是将第一终端设备的数据包路由或重定向到网元A。
举例说明：假设网元A为在线开户系统，为了实现在线开户，SMF网元可以向UPF网元发送会话建立请求消息，该请求消息中包括会话标识、在线开户系统所在网络名称(或IP地址)及在线开户指示中的至少一个，以指示UPF将PDU会话的所有数据包(报文)路由到在线开户系统，以建立第一终端设备到在线开户系统的PDU会话。其中，该PDU会话为可达在线开户系统的PDU会话，即，所有业务流数据包只能被路由或重定向(针对目的地址不是在线开户系统的数据包)到在线开户系统。
步骤D2：第一终端设备向网元A发送终端设备的信息、接入位置信息和第三指示信息中的至少一个。
其中，终端设备的信息、接入位置信息和第三指示信息中的至少一个用于指示第二网元获取允许信息。并且，终端设备的信息可以携带在新增的字段中或新增的消息中，以指示根据终端设备的信息获取允许信息。
步骤D3：网元A向终端设备发送允许信息获取请求，用以获取允许第一终端设备在接入位置信息对应的接入位置接入网络的允许信息。
具体来讲，在建立了第一终端设备与第二网元(即网元A)进行通信的会话后，第一终端设备可利用该会话通道向网元A发送终端设备标识、接入位置信息和第三指示信息中的至少一个，用于指示网元A向终端设备发送允许信息获取请求，以获取允许第一终端设备在接入位置信息对应的接入位置接入网络的允许信息。
其中，终端设备可以包括第一终端设备和第二终端设备中的至少一个，第二终端设备为除了第一终端设备之前的其他终端设备，具体介绍请参见上述实施例。
还需要说明的是，一种可选的实现方式是，在执行步骤D2之前，第一网元还需要向网元B发送信息发送指示，该信息发送指示用于指示网元B向第一终端设备下发网元A的地址信息，该地址信息用于第一终端设备与网元A建立连接，以向其发送终端设备标识、接入位置信息和第三指示信息中的至少一个。
具体来讲，在本实现方式中，与网元A类似，网元B可以是提供服务的AF网元，可以与第一终端设备直接进行数据交互，用以为第一终端设备提供相应的服务。基于此，当第一终端设备无法与网元A之间进行数据传输时，第一终端设备也可以通过网元B获取网元A的地址信息(如网元A所在网络的网络名称和网元A的IP地址和FQDN中的一项或多项内容)，进而可以通过该地址信息与网元A建立连接，以实现后续的网络接入流程。
在本申请实施例中，通过上述(1)(2)(3)(4)中至少一种实现方式，触发了第一终端设备的网络接入流程后，进一步可以实现第二网元获取允许信息的步骤，具体实现过程可以包括以下步骤F1-F2:
步骤F1：第二网元向终端设备发送允许信息获取请求。
其中，允许信息获取请求中包括第一终端设备的接入位置信息，该允许信息获取请求用于确认第一终端设备是否能够在接入位置信息对应的接入位置接入网络。终端设备包括第一终端设备和第二终端设备中的至少一个。具体的，通过第一终端设备或第二终端设备与网元A的交互，获取允许信息的具体实现过程可以包括以下两种实现方式：
1)在第一种实现方式中，通过第一终端设备获取允许消息，如图8所示，步骤F1的具体实现过程可以包括：第一网元向网元A发送包括第一终端设备标识和/或接入位置信息的第一允许信息获取请求，以便网元A基于允许信息获取请求包含的内容，向第一终端设备发送第二允许信息获取请求。
其中，第一网元向网元A发送的第一允许信息获取请求还包含了上述步骤A6中AMF网元向网元A发送的第一指示信息(如在线开户指示)、终端设备的信息以及终端设备对应的接入管理单元的标识中的至少一个、或者包含了上述步骤B7中UDM网元向网元A发送的第一指示信息(如在线开户指示)、终端设备的信息以及终端设备对应的接入管理单元的标识中的至少一个、或者包含了上述步骤C6中UDM网元向网元A发送的第一指示信息(如在线开户指示)、终端设备的信息以及终端设备对应的接入管理单元的标识中的至少一个，或者也可以包括上述步骤D2中第一终端设备向网元A发送的终端设备标识、接入位置信息和第三指示信息中的至少一个。
网元A在接收到第一允许信息获取请求后，可以向该请求中包括的第一终端设备的标识对应的第一终端发送第二允许信息获取请求，该第二允许信息获取请求可以包括第一终端标识和/或第一终端设备的接入位置信息，进而第一终端设备可以通过预先与网元A建立的会话通道，向网元A(即第二网元)发送允许消息，以确认允许第一终端设备在接入位置信息对应的接入位置接入网络，即，第二网元可以通过与第一终端设备之间的交互操作，来确认第一终端设备是否在接入位置信息对应的接入位置接入网络。
举例说明：假设网元A为在线开户系统，第一网元为AMF网元，第一终端设备为用户的设备A。则AMF网元先向SMF网元发送包括设备A的标识(如SUPI)、接入位置信息和第一指示信息中至少一项的第一允许信息获取请求，然后，SMF网元可以将该第一允许信息获取请求中包含的上述参数中的至少一个转发给UPF网元，接着，UPF网元为设备A建立到在线开户系统的PDU会话。此外，SMF网元可以将该第一允许信息获取请求发送至在线开户系统或者由设备A通过上述PDU会话发送第一允许信息获取请求给在线开户系统。进而，在线开户系统可以向设备A推送需要用户填写信息的开户页面，比如，可以先将设备A的接入的位置参数(如line ID)转化成用户可读取的位置信息(如：xx市xx街道xx小区xx号)，再将这些信息对应显示在开户页面上，以便用户在该页面上填写出对应的开户信息，如开户类型、业务类型、带宽、有效期限等内容，即确认设备A是否可以在接入位置信息对应的位置接入网络，并通过设备A将这些内容返回至在线开户系统。
2)在第二种实现方式中，签约信息中包括了第一终端设备标识与第二终端设备标识之间的映射关系，该映射关系指的是第一终端设备的标识与第二终端设备标识之间具有的对应关系，基于此，第一网元可以根据第一终端设备的标识与该映射关系得到对应的第二终端设备标识。即，在知晓第一终端设备的标识的情况下，根据该对应关系，即可获取到第 二终端设备的标识。
基于此，在本实现方式中，若第一终端设备是没有人机交互界面的终端设备(如5G-RG)，则可以在知晓第一终端设备的标识的情况下，根据该对应关系，获取到第二终端设备的标识，并从第二终端设备获取允许消息，如图9所示，步骤F1的具体实现过程可以包括：第一网元向网元A发送包括第一终端设备的标识和/或接入位置信息的第三允许信息获取请求，以便网元A向第二终端设备发送第四允许信息获取请求。
其中，第一网元向网元A发送的第三允许信息获取请求同样还可以包含上述步骤A6中AMF网元向网元A发送的第一指示信息、终端设备的信息以及终端设备对应的接入管理单元的标识中的至少一个、或者包含上述步骤B7中UDM网元向网元A发送的第一指示信息、终端设备的信息以及终端设备对应的接入管理单元的标识中的至少一个、或者包含上述步骤C6中UDM网元向网元A发送的第一指示信息、终端设备的信息以及终端设备对应的接入管理单元的标识中的至少一个，或者也可以包括上述步骤D2中第一终端设备向网元A发送的终端设备标识、接入位置信息和第三指示信息中的至少一个。
网元A在接收到第三允许信息获取请求后，可以向与该请求中包括的第二终端设备标识对应的第二终端设备发送第四允许信息获取请求，该第四允许信息获取请求可以包括第一终端设备的接入位置信息，进而网元A可以通过与第二终端设备之间的交互操作，来确认第一终端设备是否在接入位置信息对应的网络接入。
举例说明：假设网元A为在线开户系统，第一网元为AMF网元，且第一终端设备是5G-RG，第二终端设备为用户的手机B，且5G-RG的标识与手机B的标识之间具有一一对应的关系。则AMF网元向SMF网元或在线开户系统发送包括第二终端设备标识和接入位置信息的第三接入确认请求。SMF网元可以将该第三允许信息获取请求转发给UPF网元，接着，UPF网元可以将该第三允许信息获取请求发送至在线开户系统。
进而，在线开户系统可以向手机B推送需要用户填写信息的开户页面，比如，可以先将5G-RG(第一终端设备)的接入的位置参数(如line ID)转化成用户可读取的位置信息，再将这些信息对应显示在开户页面上，以便用户在该页面上填写出对应的开户信息，如开户类型、业务类型、带宽、有效期限等内容，即确认第一终端设备5G-RG是否可以在接入位置信息对应的接入位置接入网络，并通过手机B将这些内容返回至在线开户系统。
需要说明的是，第二终端设备还可以是用户通过其登录社交软件(如邮箱、微信等)的账户的终端设备，用以执行上述步骤，具体实现过程与上述过程类似，在此不再赘述。
需要说明的是，在上述两个示例中，也可以利用现有或未来出现的短消息触发流程，来确认是否允许第一终端设备在接入位置信息对应的接入位置接入网络，比如，网元A可以向第一终端设备或第二终端设备发起短消息，短信的内容及显示形式本申请实施例不做限制，可根据实际情况进行配置，比如，短信的内容及显示形式可如图10所示的三种情况。其中，如果是图10左侧显示的短消息，则用户在通过第一终端设或第二终端设备点击相关网址链接，登录到在线开户系统填写对应的开户信息，或者，可以入图10中间以及右侧图所示，可以将部分短信内容自动显示出来，由用户来确认，如用户名及位置等，同时显示出需要用户填写的开户信息，如业务类型、带宽、有效期限等。
或者，网元A可以先将第一终端设备的外部标识或第一终端设备标识发送至NEF网元，再由NEF网元将该第一终端设备的外部标识或第一终端设备标识发送给UDM网元。上述第一终端设备的外部标识是网元A上标识第一终端设备的标识信息，如常规公共签约标识(GPSI：Generic Public Subscription Identifier)。第一终端设备的外部标识可以与第一终端设备标识相同或不同。UDM网元可以根据第一终端设备标识或第一终端设备的外部标识查找第一终端设备签约数据，获取第二终端设备标识，并将第二终端设备标识发送至NEF网元，进而，NEF网元可以向第二终端设备标识对应的第二终端设备发起短消息流程，包括NEF发送第二终端设备标识给UDM，以获取UDM返回的第二终端设备对应的SMSF(Short Message Service Function)标识。后续由SMSF基于现有流程向第二终端设备发送短消息。或者，NEF网元将第一终端设备标识发送给UDM网元，UDM返回的第二终端设备对应的SMSF(Short Message Service Function)标识，后续由SMSF基于现有流程向第二终端设备发送短消息。对于短信的内容及显示形式，本申请实施例也不做限制，可根据实际情况进行配置，比如，短信的内容及显示形式可如图10所示的三种情况等。
步骤F2：第二网元接收来自终端设备的允许消息，并将其发送至第一网元，以便第一网元根据该允许消息允许第一终端设备在接入位置信息对应的接入位置接入网络。
第二网元在向终端设备发送接入允许消息获取请求后，会接收到终端设备返回的允许消息，接着，第二网元即可将该允许消息发送至第一网元，以便第一网元根据该允许消息允许第一终端设备在接入位置信息对应的接入位置接入网络。可以理解的是，终端设备也可以将允许消息直接发送至第一网元，具体实现方式可根据实际情况进行选择，本申请实施例对此不进行限制。
举例说明：假设网元A为在线开户系统，第一网元为AMF网元或UDM网元，则终端设备可以将允许消息发送至在线开户系统，进而在线开户系统可以将该允许消息发送给AMF网元或UDM网元，或者，在线开户系统也可以将该允许消息先发送至NEF，再由NEF转发给AMF网元或UDM网元，其中，该允许消息中可以包含有第一终端设备的标识和接入位置信息(如line ID)、业务类型以及有效时限(如有效期到xx年xx月xx日)中的一种或多种。
需要说明的是，在本申请的一种可能的实现方式中，步骤S203中“第一网元获取允许信息”还可以包括：第一网元获取签约信息中的第一参数，其中，第一参数用于指示当第一终端设备的接入位置信息不属于签约位置信息时，允许第一终端设备在接入位置信息对应的接入位置接入网络。
在本实现方式中，若第一网元在获取到第一终端设备的签约信息后，通过对该签约信息进行分析，从中获取到了第一参数，且该第一参数指示了当第一终端设备的接入位置信息不属于签约位置信息时，允许第一终端设备在接入位置信息对应的接入位置接入网络。则表明无需第一网元在利用上述步骤从第二网元获取允许信息，即可直接根据签约信息中包含的第一参数，允许第一终端设备在接入位置信息对应的接入位置接入网络，从而可以快速、便捷的实现了第一终端设备的网络接入。
进一步的，当第一网元为接入管理网元(如AMF网元或MME网元)时，接入管理网元 获取到允许消息之后，通过发送消息的方式，来告知第一终端设备可以在接入位置信息对应的接入位置接入网络。可选的，AMF网元可以删除第一终端设备的接入受限指示。此外，AMF向UDM网元发送签约信息更新请求，以完成签约信息的更新。其中，签约信息更新请求中包括第一终端设备的接入位置信息。签约信息更新请求用于根据第一终端设备的接入位置信息对第一终端设备的签约位置信息进行更新，如将第一终端设备的接入位置信息作为第一终端设备的签约位置信息。
具体来讲，AMF网元在获取到允许消息，确认第一终端设备能够在接入位置信息对应接入位置接入网络之后，可以向UDM网元发送包括第一终端设备的接入位置信息(如line ID)的签约信息更新请求，以便UDM网元更新第一终端设备对应的签约信息，即，UDM网元可以将第一终端设备的接入位置信息(如line ID)写入允许接入的区域列表(line ID list)。同时，还可以存储与此位置区域相关的业务类型、接入有效时限等内容。此外，UDM网元也可以将第一终端设备更新的签约信息发送给UDR进行数据存储。
或者，当第一网元为UDM网元时，网元A或终端设备将允许信息发送至UDM网元后，即UDM网元在获取到允许消息，确认第一终端设备允许在接入位置信息对应的网络接入，UDM网元可以根据该允许信息中包括的第一终端设备的接入位置信息，对第一终端设备对应的签约信息进行更新，如将第一终端设备的接入位置信息作为第一终端设备的签约位置信息。此外，UDM网元向AMF网元发送签约数据更新，更新的签约数据中包括第一终端设备的接入位置信息作为签约的位置信息，用以指示第一终端设备的接入位置信息属于签约位置信息，便于AMF网元为第一终端设备提供服务(即允许第一终端设备在接入位置信息对应的接入位置接入网络)。可选的，AMF网元可以删除第一终端设备的接入受限指示。同时，AMF网元通知第一终端设备可以在接入位置信息对应的接入位置接入网络。
具体来讲，网元A或终端设备将包括第一终端设备在接入位置信息和标识等信息的允许信息发送至UDM网元后，UDM网元可以将第一终端设备的接入位置信息(如line ID)写入允许接入的区域列表(line ID list)。同时，还可以存储与此位置区域相关的业务类型、接入有效时限等内容。此外，UDM网元也可以将第一终端设备更新的签约信息发送给UDR进行数据存储，并将该更新的签约信息发送至AMF网元，用以指示第一终端设备的接入位置信息属于签约位置信息，便于AMF网元为第一终端提供正常服务。可选的，AMF网元通知第一终端设备可以在接入位置信息对应的接入位置接入网络。
或者，网元A或终端设备也可以通过NEF网元将允许信息先发送至UDR网元，用以更新第一终端设备的签约信息，之后，再由UDR网元向UDM网元发送签约信息更新指示，以指示UDM网元更新第一终端设备的签约信息，进而UDM网元可以将更新后的签约信息发送至AMF网元，用以指示第一终端设备的接入位置信息属于签约位置信息，便于AMF网元为第一终端提供正常服务(即允许第一终端设备在接入位置信息对应的接入位置接入网络)。可选的，AMF网元通知第一终端设备可以在接入位置信息对应的接入位置接入网络。
需要说明的是，在执行步骤F1之前，即，第一网元向终端设备发送允许消息获取请求之前，第一网元或/和接入网络侧(如RAN)可以启动第一定时器，以实现对网络接入时间 的实时监控。并且，当第一定时器超时之前，若第一网元接收到终端设备的允许消息，则删除上述定时器。否则，当第一定时器超时后，终端设备的接入流程仍然未完成或未成功，则第一网元或/和接入网络侧(如RAN)拒绝终端设备的接入请求。
具体来讲，第一网元(如AMF网元或UDM网元)可以在本地为网络接入流程设置一个较长时间的定时器，以实时监控该网络接入流程。当该定时器的计时时间达到第一预设时间段结束之前，若第一网元接收到终端设备的允许消息，则可以根据该允许消息确认允许第一终端设备在接入位置信息对应的接入位置接入网络，进一步的，第一网元还可以将该允许信息发送至第一终端设备。其中，第一预设时间段指的是预先设置的第一终端设备接入一次网络所最多需要花费的时间，若超过了该时间段，则说明此处网络接入未成功，需要重新进行下一次网络接入操作。
并且，一种可选的实现方式是，若第一终端设备的接入流程失败或当第一定时器超时后，第一网元未接收到来自终端设备的接入确认消息，则第一网元可以向第一终端设备发送第二定时器，其中，第二定时器用于指示第一终端设备在第二定时器超时后发送接入请求。即指示第一终端设备在第二定时器超时之前不能发送接入请求到网络。
在本实现方式中，若第一定时器超时后，第一网元仍未接收到终端设备发送的允许消息，则第一网元可以确认第一终端设备的接入位置信息不属于签约位置信息，即，不允许第一终端设备在接入位置信息对应的接入位置接入网络。此时，第一网元即可向第一终端设备发送第二定时器息，该第二定时器信息用于指示第一终端设备在第二定时器超时后发送接入请求。
其中，可以利用第二定时器设置一个等待时间段，以指示第一终端设备可以在等待时间满足该时间段(即第二定时器超时)后，重新进行下一次接入网络的操作，即，重新发送一次接入请求。
需要说明的是，除了第一网元外，还可以由第一终端设备来发起网络接入时间的实时监控，具体来讲，第一终端设备可以在与无线接入网(radio access network，RAN)逻辑网元交换的信息(如Message 3或Message 5)中，增加“长时间网络接入”指示消息，表示该网络接入过程可能需要较长时间。则RAN在接收到该指示后，可以在本地为网络接入流程启动上述第一定时器，用以监控该网络接入流程。当该第一定时器超时后，如果网络接入流程未能正常结束，例如，RAN还没有收到AMF网元发送的任何N2消息(如downlink NAS transport消息或initial context setup request消息)，则可以判断出此处网络接入失败，需要断开与第一终端设备的空口连接。
参见图11，该图为本申请实施例提供的另一种接入网络方法的流程图。下面对该方法进行介绍。
S1101：第一终端设备向第一网元发送接入请求。
其中，接入请求表征了第一终端设备有接入网络的需要，且该接入请求不包括第一终端设备的接入位置信息。但该接入请求消息可以包括“长时间网络接入”指示消息，用以表示该网络接入过程可能需要较长时间。
S1102：第一终端设备接收第一网元根据接入请求发送的接入成功消息。
第一终端设备在通过接入网将接入请求发送至第一网元后，第一网元可以根据该接入请求，通过执行上述步骤S202-S04，获取到接入成功消息，并可以将该接入成功消息发送至第一终端设备，相关内容请参见上述步骤S202-S04的详细介绍。
需要说明的是，在执行本步骤S1102之前，还可以先执行下述步骤G1-G3，以便第二网元可以从第一终端设备获取到允许信息，并反馈至第一网元。
步骤G1:第一终端设备接收来自第二网元的接入确认请求。
其中，接入确认请求即为上述步骤F1的1)中所描述的“第二允许信息获取请求”，可以包括网页、短消息和邮件中的一项或多项，具体内容请参见步骤F1的1)中的详细介绍。
步骤G2:第一终端设备根据接入确认请求获取允许信息，其中，允许信息为允许第一终端设备在接入位置信息对应的接入位置接入网络的信息。
第一终端设备接收到来自第二网元的接入确认请求后，进一步可以根据该接入确认请求中包括第一终端设备的接入位置信息，来获取允许第一终端设备在接入位置信息对应的接入位置接入网络的允许消息。
其中，允许信息可以包括基于第一终端设备的本地配置或本地策略获取的允许信息。或者也可以包括基于用户的指示或基于用户的操作获取的允许信息。
