Description

会话创建方法及相关设备 技术领域
本申请涉及通信技术领域，尤其涉及一种会话创建方法及相关设备。
背景技术
现有的通信系统中上行数据通过采用会话创建的方式，在第三代合作计划(3rd Generation Partnership Project，简称3GPP)协议用户设备路由选择策略(英文：UE route selection policy，简称：URSP)规则中在流量描述符(英文：Traffic descriptor)中定义了应用程序标识符(英文：Application descriptors)选项。该Application descriptors可以实现匹配5GC网络配置，但是现有的Application descriptors可能被篡改或者伪造，导致会话创建的混乱，影响网络可靠性。
发明内容
本申请实施例公开了一种会话创建方法，能够实现对Application descriptors的有效管理，实现会话创建，提高网络可靠性。
本申请实施例第一方面公开了一种会话创建方法，包括：
用户设备UE执行网路连接时，获取第一应用程序的签名证书或签名证书的数字指纹；
UE匹配第一应用程序的签名证书或签名证书的数字指纹与网络侧下发的用户设备路由选择策略URSP规则中的应用程序描述符Application descriptors，UE进行所述第一应用程序的会话创建。
本申请实施例第二方面公开了一种会话通信方法，所述方法包括如下步骤：
网络设备向用户设备UE发送包含第一应用程序对应的应用程序描述符application descriptors的用户设备路由选择策略URSP策略消息，
网路设备接收所述UE发送的会话请求，通过会话请求创建所述第一应用程序的会话。
本申请实施例第三方面公开了一种终端，包括处理器、存储器、通信接口，以及一个或多个程序，所述一个或多个程序被存储在所述存储器中，并且被配置由所述处理器执行，所述程序包括用于执行第一方面所述的方法或第二方面所述的方法中的步骤的指令。
本申请实施例第四方面公开了一种计算机可读存储介质，其特征在于，存储用于电子数据交换的计算机程序，其中，所述计算机程序使得计算机执行第一方面或第二方面所述的方法中所述的方法。
本申请实施例第五方面公开了一种计算机程序产品，其中，上述计算机程序产品包括存储了计算机程序的非瞬时性计算机可读存储介质，上述计算机程序可操作来使计算机执行如本申请实施例第一方面或第二方面所述的方法中所描述的部分或全部步骤。该计算机程序产品可以为一个软件安装包。

附图说明
为了更清楚地说明本申请实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图是本申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1是本申请实施例提供的一种通信系统的结构示意图；
图2是本申请实施例提供的一种会话创建发送方法；
图3是本申请实施例提供的一种会话通信发送方法；
图4是本申请实施例提供的一种会话创建发送方法；
图5是本申请实施例提供的一种用户设备发送方法；
图6是本申请实施例提供的一种网络设备的结构示意图；
图7是本申请实施例提供的一种设备的结构示意图。
具体实施方式
本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释，而非旨在限定本申请。本申请的说明书和权利要求书及所述附图中的术语“第一”、“第二”、“第三”和“第四”等是用于区别不同对象，而不是用于描述特定顺序。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。
下面结合本申请实施例中的附图对本申请实施例进行描述。
本申请中术语“和/或”，仅仅是一种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这三种情况。另外，本文中字符“/“，表示前后关联对象是一种“或”的关系。
本申请实施例中出现的“多个”是指两个或两个以上。本申请实施例中出现的第一、第二等描述，仅作示意与区分描述对象之用，没有次序之分，也不表示本申请实施例中对设备个数的特别限定，不能构成对本申请实施例的任何限制。本申请实施例中出现的“连接”是指直接连接或者间接连接等各种连接方式，以实现设备间的通信，本申请实施例对此不做任何限定。
请参见图1，图1是本申请实施例提供的一种通信系统的结构示意图，该通信系统包括：基站10和UE20，其中基站与UE通过无线通信连接，该无线通信包括但不限于：LTE连接、新空口(英文：new radio，简称：NR)连接；当然在实际应用中，还可以是其他的连接方式，本申请并不限制上述连接的具体方式。上述基站可以为eNodeB，也可以为NR基站或接入点(英文：access point，简称：AP)。
本申请实施例中的终端可以指各种形式的UE、接入终端、用户单元、用户站、移动站、MS(英文：mobile station，中文：移动台)、远方站、远程终端、移动设备、用户终端、终端设备(英文：terminal equipment)、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话、无绳电话、SIP(英文：session initiation protocol，中文：会话启动协议)电话、WLL(英文：wireless local loop，中文：无线本地环路)站、PDA(英文：personal digital assistant，中文：个人数字处理)、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、车载设备、可穿戴设备，未来5G网络中的终端设备或者未来演进的PLMN(英文：public land mobile network，中文：公用陆地移动通信网络)中的终端设备等，本申请实施例对此并不限定。
5GC网络要求终端通过网络下发的URSP规则进行上行发送数据路由匹配和选择，根据URSP规则可以复用已建立的PDU会话，或者新建立PDU Session。在3GPP协议URSP规则中在Traffic descriptor中定义了Application descriptors选项，终端根据网络下发的URSP规则通过应用程序标识符匹配上行数据路由。URSP规则中的应用标识符可以被网络运营商针对不要应用程序提供有区别的QoS服务质量，进而产生有区别的流量控制策略或者付费业务。3GPP协议中定义了URSP规则以及可选的Application descriptors应用标识符选项，并没有具体规定应用标识符如何分配和获取。运营商如何控制分配应用程序的APP ID去匹配5GC网络配置，终端在评估和选择URSP路由规则时候如何获取应用程序APP ID以及如何防止应用程序的APP ID在应用分发、应用安装和终端操作系统中被篡改或者伪造。
具体地，在3GPP网络连接中，根据不同的技术场景会对不同的应用程序创建不同的PDU会话，因为不同的应用程序可能具有不同的服务质量(英文：Quality of Service，简称：Qos)，针对PDU会话创建，会依据终端在评估和选择URSP路由规则时候会获取APP的Application descriptors(例如APP ID)，如果应用程序的Application descriptors伪造或篡改，会导致会话建立的混乱，进而影响网络的可靠性。
请参见图2，图2是本申请实施例提供的一种会话创建方法，该方法在如图1所示的通信系统内执行，该方法包括但不限于如下步骤：
