具体实施方式
下面将结合附图对本申请实施例中的技术方案进行描述。
本申请涉及到的概念和术语的定义或解释如下。
本申请涉及到的概念和术语的定义或解释如下。
应用程序APP，是指设备安装的各种应用程序，如视频应用程序、浏览器应用程序等。
移动国家号码(Mobile Country Code，MCC)，由3位数字组成，唯一地识别移动用户 所属的国家。我国为460。
移动网络号码(Mobile Network Code，MNC)，由两位数字组成，用于识别移动用户所归属的移动网。邮电部门GSM PLMN网为00，“中国联通公司”GSM PLMN网为01。
协议数据单元(Protocol Data Unit，PDU)，是指对等层次之间传递的数据单位。物理层的PDU是数据位(bit)，数据链路层的PDU是数据帧(frame)，网络层的PDU是数据包(packet)，传输层的PDU是数据段(segment)，其他更高层次的PDU是数据(data)。
PDU会话Session，是第五代5G移动通信系统中的切片网络的粒度单位。
网络切片，是一种按需组网的方式，可以让运营商在统一的基础设施上分离出多个虚拟的端到端网络，每个网络切片从无线接入网承载网再到核心网上进行逻辑隔离，以适配各种各样类型的应用。在一个网络切片中，至少可分为无线网子切片、承载网子切片和核心网子切片三部分。
用户设备路由选项策略(UE Route Selection Policy，URSP)，是5G核心网5GC从策略控制功能实体(Policy Control Function，PCF)向用户设备(User Equipment，UE)提供的策略信息之一。UE使用该策略来确定如何路由数据外向通路。通过URSP规则UE可以确定检测到的应用程序是否可以与已经建立的PDU会话相关联，是否可以路由到PDU会话之外的非non-3GPP通路，或者是否可以建立新的PDU会话。URSP规则中一个重要的输入数据就是通路描述符(Traffic Descriptor，TD)中的参数，这些参数可以由应用在发起网络请求时携带。操作系统获取到与应用程序关联的Traffic Descriptor参数后，并且UE从网络获取到URSP规则列表后，按照URSP评估的规则匹配出相应的路由选择描述符RSD，然后按照RSD参数表示的路由通路选择数据路由。
本申请实施例的技术方案可以应用于如图1A所示的示例通信系统100，该示例通信系统100包括终端110和网络设备120，终端110与网络设备120通信连接。
该示例通信系统100例如可以是：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、先进的长期演进(Advanced long term evolution，LTE-A)系统、新无线(New Radio，NR)系统、NR系统的演进系统、免授权频谱上的LTE(LTE-based access to unlicensed spectrum，LTE-U)系统、免授权频谱上的NR(NR-based access tounlicensed spectrum，NR-U)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、下一代通信系统或其他通信系统等。
通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(Device to Device，D2D)通信，机器到机器(Machine to Machine，M2M)通信，机器类型通信(Machine Type Communication，MTC)，以及车辆间(Vehicle to Vehicle，V2V)通信等，本申请实施例也可以应用于这些通信系统。可选地，本申请实施例中的通信系统可以应用于载波聚合(Car rier Aggregation，CA)场景，也可以应用于双连接(Dual Connectivity，DC)场景，还可以 应用于独立(Standalone，SA)布网场景。
本申请实施例对应用的频谱并不限定。例如，本申请实施例可以应用于授权频谱，也可以应用于免授权频谱。
本申请实施例中的终端110可以指用户设备、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端还可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、中继设备、车载设备、可穿戴设备，未来5G网络中的终端或者未来演进的公用陆地移动通信网络(public land mobile network，PLMN)中的终端等，本申请实施例对此并不限定。如图1B所示，本申请实施例终端中的终端110可以包括一个或多个如下部件：处理器110、存储器120和输入输出装置130，处理器110分别与存储器120、输入输出装置130通信连接。
本申请实施例中的网络设备120可以是用于与终端通信的设备，该网络设备可以是LTE系统中的演进型基站(evoled NodeB，eNB或eNodeB)，还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器，或者该网络设备可以为中继设备、接入点、车载设备、可穿戴设备以及未来5G网络中的网络设备或者未来演进的PLMN网络中的网络设备，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(baseband unit，BBU)，或，分布式单元(distributed unit，DU)等，本申请实施例并不限定。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括有源天线单元(active antenna unit，AAU)。CU实现gNB的部分功能，DU实现gNB的部分功能。比如，CU负责处理非实时协议和服务，实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能。DU负责处理物理层协议和实时服务，实现无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层和物理(physical，PHY)层的功能。AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令，也可以认为是由DU发送的，或者，由DU+AAU发送的。可以理解的是，网络设备可以为包括CU节点、DU节点、AAU节点中一项或多项的设备。此外，可以将CU划分为接入网(radio access network，RAN)中的网络设备，也可以将CU划分为核心网(core network，CN)中的网络设备，本申请对此不做限定。
在本申请实施例中，终端110或网络设备120包括硬件层、运行在硬件层之上的操作系统层，以及运行在操作系统层上的应用层。该硬件层包括中央处理器(central processing unit，CPU)、内存管理单元(memory management unit，MMU)和内存(也称为主存)等硬件。该操作系统可以是任意一种或多种通过进程(process)实现业务处理的计算机操作系统，例如，Linux操作系统、Unix操作系统、Android操作系统、iOS操作系统或windows 操作系统等。该应用层包含浏览器、通讯录、文字处理软件、即时通信软件等应用。并且，本申请实施例并未对本申请实施例提供的方法的执行主体的具体结构特别限定，只要能够通过运行记录有本申请实施例的提供的方法的代码的程序，以根据本申请实施例提供的方法进行通信即可，例如，本申请实施例提供的方法的执行主体可以是终端，或者，是终端中能够调用程序并执行程序的功能模块。
URSP是5G核心网5GC从策略控制功能(Policy Control Function，PCF)实体向用户设备(User Equiment，UE)提供的策略信息之一。UE使用该策略来确定如何路由数据外向通路。通过URSP规则UE可以确定检测到的应用程序是否可以与已经建立的PDU会话相关联，是否可以路由到PDU会话之外的non-3GPP通路，或者是否可以建立新的PDU会话。
URSP包含一个或者多个URSP规则，URSP规则由以下部分组成：
1.URSP优先级
2.Traffic Descriptor，它包含如下参数
1)Match-all Traffice descriptor,或者
2)至少如下一个参数之一
a.一个或者多个应用程序的身份标识AppliCation Identifiers
b.一个或多个网际互连协议描述符IP Descriptors
c.一个或则和多个非网际互联协议描述符non-IP Descriptors(与IP Descriptors互斥)
d.一个或多个数据网络名称DNN
e.一个或多个连接能力Connection Capabilities(协议上仅定义了4种：ims supl internet mms)
f.一个或多个域描述符Domain Descriptors
3.一个或多个路由选择描述符Route Selection Descriptor，它包含如下参数
1)PDU Session Type(可选)以及如下参数
a.会话及服务连续性模式SSC Mode
b.一个或多个单个网络切片选择协助信息S-NSSAI
c.一个或多个数据网络名称DNN
d.首选访问类型(3GPP或者非3GPP)Prefered Access Type
e.多路访问首选项Multi-access Preference
f.时间窗Time window
g.位置标准Location Criteria
2)非无缝非3GPP卸载指示non-seamless non-3GPP offload indication
操作系统获取到与应用程序关联的Traffic Descriptor参数后，并且UE从网络获取到URSP规则列表后，按照URSP评估的规则匹配出相应的RSD，然后按照RSD参数表示的路由通路选择数据路由。URSP规则中一个重要的输入数据就是TD中的参数(简称TD参数)，这些参数可以由应用在发起网络请求时通过接口携带也可以通过其他方式配置。
目前，如何为终端配置应用程序所签约的多个运营商的TD参数，目前协议还未明确约 定。
针对上述问题，本申请实施例提出一种通路描述符传输方法，下面结合附图进行详细说明。
请参阅图2，图2是本申请实施例提供的一种通路描述符传输方法的流程示意图，如图所示，该方法包括：
步骤201、网络设备向终端发送第一应用程序的第一配置文件；
其中，所述第一配置文件包括所述第一应用程序的通路描述符TD参数，所述TD参数包括与所述第一应用程序签约的多个运营商的TD参数。
其中，所述第一应用程序可以是终端安装的系统应用或者第三方应用，如视频类应用、游戏类应用、办公类应用等，此处不做唯一限定。
需要注意的是，步骤201中的网络设备可以是移动网络中的基站(如：5G系统中的gNB，负责中转第一配置文件给终端)、或者核心网侧的网络服务器(如：5GC中的PCF)、或者用于通过应用程序的APK的第三方服务器、或者网络侧提供OTA服务的功能网元、或者网络侧提供短信消息服务的功能网元，此处不做唯一限定。
此外，步骤201仅为可选步骤，并非唯一方式，就是说，终端可以通过线下购买SIM卡等方式，获取到第一配置文件，此种情况下无需网络设备发送，又或者，其他终端通过点对点传输方式将第一配置文件同步给本终端等。
步骤202、终端获取第一应用程序的第一配置文件；
其中，所述第一配置文件包括所述第一应用程序的通路描述符TD参数，所述TD参数包括与所述第一应用程序签约的多个运营商的TD参数。
在本可能的示例中，所述TD参数包括第一标识与第一参数之间的对应关系；
其中，所述第一标识包括所述多个运营商的移动网络的身份标识，所述第一参数为所述TD参数中的参数。
在本可能的示例中，所述第一参数包括以下任意一种：数据网络名称DNN、连接能力Connection Capabilities。
在本可能的示例中，所述第一标识包括移动国家号码MCC和移动网络号码MNC。
在本可能的示例中，所述第一标识仅包括移动网络号码MNC。
举例来说，某应用程序分别与中国移动，中国联通签约了网络切片服务，中国移动为之分配了DNN是cmdnn1，中国联通为之分配的DNN是cudnn1。那么其在TD配置文件中可以配置如下信息(仅举例说明，配置文件形式和内容可以有多种方式)：
AppId＝appid1//比如该应用程序的AppId是appid1
IP address＝“192.168.5.23”
Port＝“8080”
<dnn
mcc＝460
mnc＝00
dnn＝cmdnn1//中国移动dnn
/>
<dnn
mcc＝460
mnc＝01
dnn＝cudnn1//中国联通dnn
/>
以Traffic Descriptor配置文件与应用程序安装包一同发布为例(还可以有其他多种发布方式)，当应用程序安装到操作系统中，操作系统会根据当前的SIM卡信息匹配出对应的数据网络名称DNN等参数，于是便可获取该应用程序对应该运营商的完整TD参数进而进行URSP规则的匹配。操作系统拿到该应用程序指定运营商的TD参数后，可以将其与该运营商URSP规则中的Traffic Descriptor参数进行匹配，匹配成功后获取RSD参数，并按照RSD参数指示建立或者选择PDU Session，从而接入到指定网络切片中去。
可见，本示例中，针对应用程序与多个运营商签约存在多个运营商的TD参数配置信息需改同步到终端的场景，通过第一配置文件包含所有签约的运营商的TD参数，并通过对应关系使得每个运营商的关键TD参数能够被准确区分开，避免造成使用混乱，提高使用准确度和成功率。
在本可能的示例中，所述第一配置文件通过以下任意一种方式发送：
①通过二次封装的方式将所述第一配置文件封装到所述第一应用程序的应用程序安装包APK中，解压所述APK以获取所述第一配置文件；
②通过运营商的网络服务器发布所述第一配置文件，接收所述网络服务器发布的所述第一配置文件；
③将所述第一配置文件配置在客户识别模块SIM卡中，从所述SIM卡中获取所述第一配置文件；
④通过运营商的移动网络的空中下载OTA服务或者短信消息推送服务配置所述第一配置文件；
⑤通过本端设备安装的运营商应用程序配置所述第一配置文件，且所述运营商应用程序以Overlay的方式更新所述第一配置文件，所述运营商应用程序通过用户身份识别SIM卡进行鉴权；(Android Overlay是一种资源替换机制，它能在不重新打包APK的情况下，实现资源文件的替换)
⑥将所述第一配置文件配置在所述第一应用程序的APK的未经签名保护的文件属性中，且每个运营商的TD参数通过对应运营商的私钥签名。
针对①，将第一配置文件以二次封装的方式存储至应用程序的APK中，由于APK本身有防篡改机制，安全性好。网络设备可以是第三方应用服务器，第三方应用服务器存储封装有第一配置文件的第一应用程序的APK，在接收到终端的下载请求后，将第一应用程序 的APK推送给终端。
针对②，运营商的网络服务器来发送，由于涉及到多个运营商的TD参数的配置信息，该网络服务器可以是任意一个运营商部署的网络服务器，或者是多个运营商共同部署的网络服务器，该网络服务器汇总所有运营商针对第一应用程序的TD参数配置信息，生成第一配置文件，并将第一配置文件发布给需要使用或者安装该第一应用程序的终端。此种方式运营商与终端之间传输第一配置文件中转节点少或者没有，链路安全性更加可控，且专用消息传输效率也会更高。
针对③，SIM卡方式支持线下安装、线上更新第一配置文件，若为虚拟SIM卡，则支持网络设备推送和配置。运营商可以在SIM卡出厂阶段预置第一配置文件，并包含一些必备应用程序所签约运营商的TD参数配置信息，后续安装到终端后，可以周期性更新以与终端的应用程序保持一致。
针对④，直接通过OTA或者短信消息推送方式传输，实现基于终端侧用户需求的个性化推送服务器，灵活性更强。
针对⑤，运营商应用程序通过用户身份识别SIM卡进行鉴权，安全性高。
针对⑥，复用APK的未经签名保护的文件属性中的闲置字段，提高利用率和传输效率。
在本可能的示例中，所述第一配置文件通过以下方式获取：通过二次封装的方式将所述第一配置文件封装到所述第一应用程序的应用程序安装包APK中，解压所述APK以获取所述第一配置文件；即针对①，所述终端获取第一应用程序的第一配置文件，包括：所述终端下载所述第一应用程序的第一应用程序安装包；所述终端解压所述第一应用程序安装包，得到所述第一应用程序的第二应用程序安装包和所述第一配置文件。
具体实现中，对于多运营商TD参数配置文件经过二次封装打包到应用程序安装包中的配置方式，当应用程序安装包下载到用户终端后，解压出来两部分，一部分为应用程序安装包，另一部分即为多运营商TD参数配置文件。操作系统可以通过获取该应用程序的TD参数配置文件来获取相应的TD参数。
例如，微信应用程序同时签约了移动、联通和电信三家运营商，且移动运营商对应配置的TD参数为TD参数1，联通运营商对应配置的TD参数为TD参数2，电信运营商对应配置的TD参数为TD参数3，则第一配置文件中的TD参数可以如表1所示，即不同运营商所配置的TD参数可以在同一个表中呈现。

在本可能的示例中，所述第一配置文件通过以下方式获取：将所述第一配置文件配置在所述第一应用程序的APK的未经签名保护的文件属性中，且每个运营商的TD参数通过对应运营商的私钥签名；即针对⑥，所述终端获取第一应用程序的第一配置文件，包括：所 述终端下载所述第一应用程序的应用程序安装包；所述终端解压所述第一应用程序的应用程序安装包，得到所述第一应用程序的未经签名保护的文件属性；所述终端从所述未经签名保护的文件属性中获取所述第一应用程序所签约的多个运营商中每个运营商的TD参数配置信息；所述终端针对所述每个运营商的TD参数配置信息进行签名校验，得到所述多个运营商的TD参数的明文信息。
具体实现中，对于将多运营商TD参数配置文件配置在APK的未经签名保护的的文件属性这种配置方式，可以将每个运营商与其TD参数配置文件以键值key-value的形式存放，每个运营商需要对其TD参数配置信息分别进行签名以防止被篡改。当应用程序APK安装到操作系统后，操作系统通过读取这部分未经签名保护的文件属性，将该应用程序对应的所有运营商的TD参数配置文件获取出来，再分别经过签名校验获取对应的TD参数明文信息。
例如，淘宝应用程序同时签约了移动、联通和电信三家运营商，且移动运营商对应配置的TD参数为TD参数1和TD参数2，联通运营商对应配置的TD参数为TD参数3和TD参数4，电信运营商对应配置的TD参数为TD参数5和TD参数6，则终端通过移动运营商的公钥校验TD参数1和TD参数2，得到TD参数1和TD参数2的明文信息，通过联通运营商的公钥校验TD参数3和TD参数4，得到TD参数3和TD参数4的明文信息，通过电信运营商的公钥校验TD参数5和TD参数6，得到TD参数5和TD参数6的明文信息，三个运营商的三组TD参数分别如表2、表3、表4所示。

其中，通过私钥加密明文形成TD参数的密文信息，该私钥可以是运营商同步给第三方应用开发商，应用开发商将公钥分发给安装对应应用程序的终端。
在本可能的示例中，所述终端获取第一应用程序的第一配置文件之后，所述方法还包括：所述终端的操作系统根据当前的SIM卡信息匹配出所述终端当前接入的第一运营商的预设参数；所述终端的操作系统根据所述预设参数，查询所述第一应用程序的TD参数，获 取所述第一运营商的第一TD参数；所述终端的操作系统根据所述第一TD参数，查询用户设备路由选项策略URSP规则，获取所述第一运营商的第一路由选择描述符RSD；所述终端的操作系统根据所述第一RSD建立或者选择第一协议数据单元PDU会话Session，以接入所述第一运营商的移动网络的网络切片。
在本可能的示例中，所述预设参数包括以下至少一种：
DNN、连接能力Connection Capabilities、网际互连协议描述符IP Descriptor、域描述符Domain Descriptor、应用程序的身份标识AppId、非网际互联协议描述符non-IP Descriptor。
例如，终端的操作系统根据当前的SIM卡信息匹配出所述终端当前接入的第一运营商的第一MNC，则可以进一步根据该第一MNC查询第一应用程序的TD参数，获取第一运营商的第一TD参数，然后根据第一TD参数查询URSP规则，获取第一运营商的第一RSD。
又例如，终端的操作系统根据当前的SIM卡信息匹配出所述终端当前接入的第一运营商的第一连接能力，则可以进一步根据该第一连接能力查询第一应用程序的TD参数，获取第一运营商的第一TD参数，然后根据第一TD参数查询URSP规则，获取第一运营商的第一RSD。
可见，本示例中，终端能够在确定当前接入的第一运营商的预设参数之后，查询解析第一配置文件得到的TD参数，获取到第一应用程序相对于第一运营商的第一TD参数，进而查询URSP获取到对应的RSD，最后根据RSD建立或者选择第一PDU Session，以接入所述第一运营商的移动网络的网络切片。由于第一配置文件包含第一应用程序的所有运营商配置的TD参数，因此整个过程无需多次查询，仅需要查询一次即可准确确定当前接入的第一运营商的预设参数所对应的第一TD参数，耗时短，效率高，且相对于直接使用预配置的TD参数的方式，第一配置文件整体被篡改的几率较小，能够防止TD参数被伪装篡改的问题，具有良好的安全性。
可以看出，本实施例中，终端获取到第一配置文件，该第一配置文件包括所述第一应用程序的通路描述符TD参数，所述TD参数包括与所述第一应用程序签约的多个运营商的TD参数，从而终端仅需要单次解析配置文件即可获取到第一应用程序所签约的所有运营商的TD参数配置信息，无需多步骤冗长操作，提高终端的应用程序被配置TD参数的效率。
