一种数据网络信息处理方法、装置、终端及存储介质
相关申请的交叉引用
本申请基于申请号为201611153360.0、申请日为2016年12月14日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本发明涉及数据处理技术领域，尤其涉及一种数据网络信息处理方法、装置及终端。
背景技术
现有技术中，终端设备(User Equipment，UE)从5G无线网络连接到核心网的架构示意图，如图1所示，在该架构中，UE同时连接到提供不同业务的数据网络中，如：移动边缘计算服务器(Edge Computing Server)和远端网络(Internet)业务。UE同时从下一代无线网和非第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)接入网接入到下一代核心网的架构，如图2所示，UE从3GPP和非3GPP接入网分别连接到数据网络，相应的，UE可以同时连接到提供不同业务的数据网络。
在如图1和图2所示的网络架构中，用户面网关(User Plane Gateway，UPGW)或用户面网络功能(User Plane Network Function，UPNF)负责在UE和数据网络之间转发业务报文，并且为UE配置访问该数据网络所使用的互联网协议(Internet Protocol，IP)参数，如：IP地址、路由信息、域名系统(Domain Name System，DNS)服务器信息等；也就是说，当UE连接到多个数据网络时，会产生多套IP参数，UE中的应用在运行发起访 问时，UE可能会面临如下问题；第一，UE运行的应用需要连接的应用服务器或平台可能位于UE连接的本地数据网络中，有的可能位于远端数据网络中，UE随机选择的应用服务器或平台如果位于远端数据网络中，则需要UE向远端数据网络的服务器发起访问，从而错过了优先访问本地网络的体验；第二，在私有业务等特定的业务数据网络中，相关的域名也是全球唯一的，这些域名也只能通过该数据网络下发的DNS服务器查询；此时，如果UE优先选择其他的数据网络的DNS服务器查询域名，通常会经过多次DNS服务器查询失败后，才能够选择正确的业务数据网络进行访问。

具体实施方式
为了进一步理解本发明实施例所述方案，下面对5G网络进行简单说明：
随着通信技术的飞速发展，关于下一代网络，即5G网络的研究正在如火如荼的进行，5G系统可以使运营商将网络作为一种服务提供给用户；也就是说，运营商能够将实体网络以“网络即服务”的形式提供连接服务，满足终端用户对于更多网络用例的广泛需求；如对于重型机械遥控操作而言，最佳的连接服务需要具有低延迟、高带宽、覆盖一定的地理区域、支持多种已知的设备类型等特点，在现有技术中，需要进行及其遥控的建筑业单位或采矿业单位通常建立一个自有网络，基于该自有网络创造一个连接服务，在不需要时将拆卸该网络；但是，未来的5G网络将使运营商能够为类似上述的小众需求提供连接服务。
5G网络将在2020年左右投入商用，届时的用例将需要新型的、可扩展的、可编程的连接服务；与现有的网络相比，5G网络需要满足更多的需求，如：网络流量将增加1000倍，需要连接的终端设备将增加100倍，支撑部分应用运行的网络速率是现有网络平均速度的100倍，甚至运行某些应用时要求零延迟，同时，整个网络系统将努力使电池的寿命达到10年或更久。
5G网络是一个新的与现有无线网络、云网络和核心网演进结合的网络，能够支持超带宽移动宽带网络、海量终端、超可靠物联网及更多种类的设 备，能够满足不同的运维需求和成千上万的应用场景；5G网络的无线部分将集成多种无线和计入方案，核心网将基于云技术和软件定义网络(Software Defined Network，SDN)技术，多种不同的接入技术可以接入统一的核心网，并借助虚拟化、SDN技术以及云技术根据场景定制网元的功能、资源分配以及不同场景的虚拟网络间的互相隔离。
移动通信技术的更新换代势必给各行各业带来诸多创新应用，移动宽带、媒体、机器类通信(Machine-Type Communication，MTC)、远程机械和智能运输系统(Intelligent Transportation System，ITS)将成为5G时代的主要用例；同时，并未所有未来的用例都要求网络速度超快、超智能及拥有支持各种类型的终端设备的能力；相反，5G网络将以灵活的方式构建，运营商可以对网络速率、网络容量以及网络覆盖率等网络性能指标进行自由灵活的组合，从而满足各个用例的具体要求；因此，为了满足上述广泛变化的用例需求，5G网络将采用基于逻辑资源而非基于物理资源的技术。
下面再介绍本发明实施例图1和图2中各网络接口的功能：NG1为UE与下一代核心网之间的控制面接口，NG2为下一代居民接入网(Residential Access Network，RAN)或non-3GPP接入网关网络功能到下一代核心网之间的控制面接口，NG3为下一代RAN或non-3GPP接入网关网络功能到下一代核心网之间的用户面接口，NG4为下一代核心网中的CPNF与UPNF之间的接口，NG5为下一代核心网中的CPNF与应用功能(服务器)之间的接口，NG6为下一代核心网中的UPNF与分组数据网络之间的接口。
