Description

一种网络切片选择方法、策略生成方法及网络节点 技术领域
本申请涉及但不限于网络通信技术领域，尤指一种网络切片选择方法、策略生成方法及网络节点。
背景技术
在过去的20多年时间里，移动通信技术得到了飞速发展，为人们生活方式、工作方式以及社会的政治、经济等各方面都带来了巨大的影响。人类社会进入高效的信息化时代，各个方面业务应用需求呈现爆发式增长，给未来无线移动带宽系统在频率、技术以及运营等各方面都带来了巨大的挑战。
随着互联网各类应用的丰富，第三方服务商对网络运营商的信息交互及网络个性需求愈来愈强烈，网络能力开放逐渐成为未来网络技术的主流。如目前移动个人用户、行业用户和SP/CP(Service Provider/Content Provider，服务提供商/内容提供商)使用的移动业务中有一部分为对时延不敏感的业务，比如软件更新和下载、音乐和视频下载等业务，而这类业务的数据流量偏大，采用正常流量套餐进行传输将会产生比较高的费用。在现网中，移动数据网络在时间和地域方面呈现明显的忙闲不均的特点，网络中存在许多空闲资源。背景流量业务(第三方应用与网络进行信令协同，在网络空闲时段传输非实时的大流量，如视频推送、软件更新等)可以把这些空闲无线资源充分利用起来，使运营商的网络能够被充分利用，同时对于用户来说能够享受到非常便宜的流量，对于SP/CP来说也可以利用低成本的背景流量通道分发业务和内容，从而促进用户对移动流量的使用，对运营商带来数据收入的增长。
移动互联时代下，运营商开放网络能力已是大势所趋。多年来，管道资源、网络优势一直是运营商的核心竞争力所在。但随着4G及5G时代的到来，丰富互联网应用逐渐使运营商成为单纯的管道提供商。因此，构建统一开放的能力提供平台，合理开放基础业务及信息等能力成为运营商构 建未来竞争力的关键所在。
图1是EPS网络能力开放架构示意图。如图1所示，该网络架构可以包括如下部分：
移动网络及网元(Mobile Network and Entity，简称为MNE)，包含控制面网元MME/SGSN(Mobility Management Entity/Serving GPRS Support Node，移动管理节点/服务GPRS支持节点)，负责信令控制及移动性管理；用户面网元PGW/GGSN(Public Data Network GateWay/Gateway GPRS Support Node，公用数据网网关/网关GPRS支持节点)，负责承载控制及会话管理；数据面网元HSS(Home Subscriber Server，归属签约用户服务器)，负责用户的签约管理；策略控制网元PCRF(Policy and Charging Rules Function，策略与计费规则功能)，负责用户Qos(Quality of Service，服务质量)及计费策略的制定及下发；及其他网元等。
能力开放平台(Capability Exposure Platform，简称为CEP)，用于根据第三方的需求，向网络请求网络资源与信息，为用户提供差异化的服务及更好的用户体验。
应用服务器(Application Server，简称为APP)，用于第三方给用户提供丰富多样的互联网服务。
电信业务运营支持系统(Business and Operation support system，简称BOSS)，包含OSS(Operation Support System，运营支撑系统)与BSS(Business support system，业务支撑系统)。BOSS是电信运营商的一体化、信息资源共享的支持系统，它主要由网络管理、系统管理、计费、营业、账务和客户服务等部分组成。其中OSS负责网络配置、网络维护、网络管理及优化等功能实现。BSS主要负责后台计费、用户授权、结算、帐务、客服、营业等功能实现。
网络编排功能(Network Orchestrator Function，简称NOF)，负责网络及网元的动态编排。
采用该能力开放架构，移动网络通过服务开放平台统一对外暴露移动网络信息和开放移动网络能力，开放的对象包括第三方应用和运营商自有 应用等。
图1中的传统蜂窝网网络架构适合单一服务型的网络。然而，使用这种垂直架构，运营商难以扩展电信网络，也很难根据不断变化的用户需求进行调整并满足新型应用的需求。
图2是能力开放的流程，包括如下步骤：
S101：应用服务器根据自身的业务流程需要向能力开放平台调用应用API(Application Protocol Interface，简称应用协议接口)，例如：调用用户轨迹应用场景中的区域位置用户密度API。
S102：能力开放平台进行应用层协议转换及需求匹配，从应用API解析出需向移动网络获取能力信息。例如：第三方应用服务器需要获取某地理区域的用户密度信息。
S103:能力开放平台向移动网络及网元获取所需的能力信息，如向网络获取某地理区域的用户密度信息。移动网络及网元为该请求申请更新网络资源，收集网络及用户信息，并将网络能力信息(如电信能力、终端信息、网络资源、网络状态等)返回给能力开放平台。如向能力开放平台返回当前的某区域位置用户密度信息。
S104：能力开放平台将从移动网络及网元获取到的网络能力信息按照应用API的需要进行封装，形成应用API调用的匹配结果。例如：将特定区域位置的用户密度信息封装成可调用的API信息。
S105：能力开放平台器将应用API的匹配结果返回给应用服务器。应用服务器根据从网络侧获取的不同API，可以实现各类应用，为用户提供差异化的服务。
能力开放网络架构可以向第三方应用提供部分网络能力的开放，第三方应用可以通过能力开放平台去请求QoS参数更新，计费策略调整(如第三方为用户付费业务)，用户偏好信息获取等服务。但并不能够满足未来5G网络需求的能力开放。
在未来网络系统中，网络将被进一步抽象为“网络切片”(network slice)：不同的网络切片为特定的业务或特定的终端或特点的区域提供连接服务，网络切片包含可动态创建的各个虚拟网元，网络切片的功能及性能实现包括：地理覆盖区域、持续时间、容量、速度、延迟、可靠性、安全性、可提供的服务和可用性等等。
不同的业务，如MBB(Mobile Broadband，移动宽带服务)业务，mMTC(massive machine type communication，大规模机器类通信服务)业务，uMTC(ultra machine type communication，超实时超可靠机器类通信服务)业务，因其业务需求(对网络切片功能及性能的需求)差异性较大，在网络侧就采用不同的网络切片提供服务，每个网络切片包含的网元、网络连接、网络资源、硬件资源等是按需建立与分配的，不同类型的网络切片可以提供不同的终端接入与业务能力，满足不同的业务需求。网络切片的创建、更新与释放由网络切片管理功能(NSMF，network slice management function)提供。
网络切片的应用差异性千差万别，不同类型的网络切片支持不同的业务需求，使网络切片性能更优化、网络切片资源分配更合理。在图3中，存在多种类型的网络切片，如物联网切片、互联网切片等。以物联网为例，物联网切片还可细分成多种类型的切片，如负责大众交通类型的网络切片，停车场类型的网络切片，楼宇监控类型的网络切片，紧急通信类的网络切片，工业控制类型的网络切片，远程抄表类型的网络切片等等。另外，网络切片也可以细分成多个子网络切片类型，不再一一举例。
发明内容
以下是对本文详细描述的主题的概述。本概述并非是为了限制权利要求的保护范围。
未来5G网络采用网络切片为不同业务提供差异化的服务，当终端面临可提供服务的多个网络切片时，能力开放平台将第三方服务的基于终端不同业务、不同状态下的网络切片需求传导给网络侧，使终端能够接入到更合适的网络切片。如汽车类终端，在汽车行驶时接入到大众交通类网络切 片，在汽车进入停车场时接入到停车场类网络切片，在汽车遇到车祸等紧急事件时接入到紧急通信类网络切片，匹配终端的业务类型和工作状态，使终端接入到匹配的网络切片，提供更佳的用户体验。因而，如何实时实地为物联网终端提供合适的网络切片选择，当终端在业务改变或状态改变时能选择合适的网络切片提供服务，是要解决的问题。

本发明的实施方式
下文中将结合附图对本发明的实施例进行说明。在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
实施例一
终端在不同的工作模式下有不同的业务需求，而不同类型的网络切片因其功能及性能不同，可以满足不同的业务需求。因此采用不同类型的网络切片为不同工作模式下的终端提供服务，使网络服务更优化，网络资源利用率更大化，用户体验更优化。
举例来说，对于物联网场景下的汽车类终端，在汽车行驶时接入到大众交通类网络切片，保证车辆运行使车辆的安全，能得到路况的及时服务；在汽车进入停车场时接入到停车场类网络切片，能准确找到空闲车位，享受停车场提供的娱乐等本地服务；在汽车遇到车祸等紧急事件时接入到紧急通信类网络切片，能保证优先向紧急中心传递车祸的图片及视频，保证不间断通信，使车祸得到迅速及时的处理。再举例来说，物联网场景下的楼宇监控类终端，平时可以采用公用网络切片接入，保证与远程服务中心必要的联系。当该楼宇中出现紧急事件、如人质劫持、火灾等特定场景时，此时楼宇监控类终端切换到紧急通信类网络切片，保证高质量的图像传输及远程的实时控制，第一时间保障救援工作的顺利开展。当终端切换到不同的业务类型、工作状态时，及时切换到匹配其业务需求的网络切片提供接入服务，使终端接入到匹配的网络切片，保证更佳的用户体验。
确定终端的工作模式与网络切片类型之间的对应关系，进而根据网络切片类型来选择切片，可满足终端在不同工作模式下的业务需求。为此，本实施例提供一种终端接入策略生成方法，如图4所示，包括：
步骤110，能力开放平台CEP获取终端在不同工作模式下的业务需求的信息，及不同网络切片类型所能满足的业务需求的信息；
本实施例中，能力开放平台从第三方APP(本申请中的第三方APP包括物联网远程服务器、物联网服务提供商、第三方应用、第三方服务等任意的第三方网络节点)获取终端不同工作模式下的业务需求，从网络切片管理功能(NSMF，network slice management function)获取不同网络切片类型所能满足的业务需求，从而生成终端接入策略。
本申请中，终端的工作模式至少根据终端的业务类型、或工作状态、或业务类型和工作状态确定。当终端的工作模式根据终端的业务类型和工作状态确定时，如果终端的业务类型或者工作状态发生变化，则终端的工作模式也发生变化。
本实施例中，终端的业务类型包括物联网业务类型和互联网业务类型中的一种或多种；终端的工作状态包括终端自身的运行状态和为终端设定的行为模式中的一种或多种。其中，终端自身的运行状态例如，汽车类终端处于行驶、停车、事故等状态时，认为其处于不同的工作状态；为终端设定的行为模式可以是第三方APP或运营商为终端设定的行为模式，例如，运营商可以为抄表类终端设定的休眠、数据上报、告警等行为模式。终端的工作状态也可以采用其他的划分方式，如简单地划分为正常工作状态和紧急工作状态，等等。
步骤120，所述CEP根据获取的信息生成终端接入策略，所述终端接入策略包含终端的工作模式与网络切片类型之间的对应关系；
本实施例中，如果有多种网络切片类型能够满足终端在一种工作模式下的业务需求，所述CEP从所述多种网络切片类型中选择一种，作为该工作模式唯一对应的网络切片类型。CEP可以根据自身配置的策略或网络运营商下发的策略，来确定该唯一对应的网络切片类型，使生成的终端接入策略中不存在一种终端的工作模式对应多种网络切片类型的情况。
本实施例中，CEP生成终端接入策略后，可采用以下一种或多种方式下发给终端或网络侧的节点。
CEP在终端接入网络切片后的注册过程中，将所述终端接入策略下发给所述终端；
CEP将所述终端接入策略下发给网络侧的策略管理服务器；
CEP将所述终端接入策略下发给终端管理服务器。例如，当终端管理服务器向CEP进行查询时，CEP下发终端接入策略给终端管理服务器。
本实施例还提供了一种能力开放平台，包括终端策略生成模块，如图5所示，所述终端策略生成模块包括：
信息采集单元10，设置为获取终端在不同工作模式下的业务需求的信息，及不同网络切片类型所能满足的业务需求的信息，其中，终端的工作模式至少根据终端的业务类型、或工作状态、或业务类型和工作状态确定；
策略生成单元20，设置为生成终端接入策略，所述终端接入策略包含终端的工作模式与网络切片类型之间的对应关系。
在一个实施例中，
所述策略生成单元设置为：如果有多种网络切片类型能够满足终端在一种工作模式下的业务需求，则从所述多种网络切片类型中选择一种，作为该工作模式唯一对应的网络切片类型。
在一个实施例中，
所述信息采集单元包括：
第一子单元，设置为从第三方应用服务器APP获取终端在不同工作模式下的业务需求的信息；
第二子单元，设置为从网络切片管理功能NSMF获取不同网络切片类型所能满足的业务需求的信息。
在一个实施例中，
所述终端的业务类型包括物联网业务类型和互联网业务类型中的一种 或多种；
所述终端的工作状态包括终端自身的运行状态和为终端设定的行为模式中的一种或多种。
在一个实施例中，
所述能力开放平台还包括：策略下发模块，设置为采用以下一种或多种方式下发所述终端接入策略：
在终端接入网络切片后的注册过程中，将所述终端接入策略下发给所述终端；
将所述终端接入策略下发给网络侧的策略管理服务器；及
将所述终端接入策略下发给终端管理服务器。
以下几个实施例中的终端接入策略，可以采用本实施例的方法生成，但并不局限于此，也可以按照其他方式生成如人工配置等。
终端的工作模式改变时(或者新增工作模式时)，可采用不同的方式选择网络切片。下面通过3个实施例对3种不同的方式进行说明。
实施例二
本实施例是由终端发起网络切片选择及切换的操作。如图6所示，本实施例的网络切片选择方法包括：
步骤210，终端获取终端接入策略，所述终端接入策略包含终端的工作模式与网络切片类型的对应关系；
本实施例中，所述终端可以通过以下方式中的一种或多种获取所述终端接入策略：

所述终端接入网络切片后，在到终端管理服务器注册的过程中，获取所述终端管理服务器下发的所述终端接入策略。
步骤220，所述终端根据所述终端接入策略确定当前工作模式对应的网络切片类型；
本步骤中，终端确定当前工作模式对应的网络切片类型，可以包括以下两种场景：第一种是终端因业务类型或工作状态变化，导致工作模式更新后，确定更新后的工作模式对应的网络切片类型；第二种是终端新增业务(原来的业务没有释放)而导致新增工作模式时，为该新增业务选择一个网络切片接入，此时确定新增的工作模式对应的网络切片类型。
步骤230，所述终端根据所述对应的网络切片类型的信息，通过服务网络切片向网络切片管理功能NSMF查询得到所述终端的目标网络切片的信息，所述目标网络切片具有所述对应的网络切片类型，用于为当前工作模式下的所述终端提供接入服务。
本申请中，服务网络切片指终端当前接入的网络切片，也即当前为终端提供服务的网络切片。
根据上一步骤可能的两种场景，本步骤的目标网络切片可以是终端需要切换到的网络切片，也可能是终端新增业务要接入到的网络切片。第一种场景下又有两种处理方式，以下分别说明。
第一种场景：
方式一，本方式下，所述终端决策发起网络切片切换后，向服务网络切片发起切换请求，从服务网络发起的去附着流程中得到目标网络切片的信息。
在该场景下，步骤220确定的是更新后的工作模式对应的网络切片类型，之后，所述终端判断服务网络切片是否具有所述对应的网络切片类型，如不具有，则决策发起网络切片切换；之后，再向NSMF查询。
查询时，所述终端向服务网络切片发送网络切片切换请求，携带所述更新后的工作模式对应的网络切片类型的信息和所述终端的信息；
服务网络切片收到网络切片切换请求后，根据所述对应的网络切片类型的信息和所述终端的信息，向所述NSMF查询得到所述目标网络切片的信息，然后对所述终端发起去附着流程。在去附着流程中将所述目标网络切片的信息通知给终端；

方式二
与第一种场景下方式一不同的是，本方式下所述终端决策发起网络切片切换后，先向服务网络切片发起查询请求，查询到目标网络切片的信息之后再由终端发起去附着操作。其中：
所述终端决策发起网络切片切换后，向服务网络切片发送网络切片查询请求，携带所述更新后的工作模式对应的网络切片类型的信息和所述终端的信息；

该场景下终端不发起原网络切片的去附着，在新的网络切片接入成功，不同接入的网络切片负责所述终端不同的业务。
