技术领域
本申请实施例涉及但不限于通信领域，具体而言，涉及但不限于网络切片的选择方法、装置及终端、计算机可读存储介质。
背景技术
移动通信的发展日新月异，渗透到人们工作、社交、生活的各个方面，给人们的生活方式、工作方式以及社会政治、经济等各方面都带来了巨大的影响。人类社会进入了信息化时代，各个方面业务应用需求呈现爆发式增长，在未来的移动网络，不仅仅提供人与人之间的通信，还要为物联网海量设备提供服务。比如虚拟现实、高清视频等有超高速率服务需求的业务，速率可以达到现在的10～100倍；比如车联网等有低延时服务需求的业务，端到端时延可以缩短5倍；物联网可以接入现在的1000倍数量的业务，而电池寿命也可以延长到现在的10倍等。
5G(5thGeneration，第五代)业务将呈现出多场景、差异化的特点，如移动上网业务聚焦带宽，自动驾驶业务需要低延时和高可靠性保障，物联网业务要支持巨大的连接数量。对此，5G的无线接入网和核心网都进行了功能重构，根据业务类型改变设备处理单元的物理部署位置，并通过切片在同一物理网络上对不同类型业务构建独立的端到端逻辑网络。
5G是一个开放网络，可以提供面向垂直行业和租赁业务的应用需求，5G承载网是5G端到端业务路径的一部分，因而要求承载网络支持5G切片的业务隔离和独立运维需求，为不同类型的业务分配不同的承载网切片。
网络切片是利用虚拟化技术在一个共享的物理网络资源之上创建多个虚拟网络，或称为切片。网络切片可以根据承载业务不同类型或不同租户而将物理网络切片成相应的虚拟网络(例如按照政企客户、家庭客户以及5G的eMBB(EnhanceMobi leBroadband，增强移动宽带)业务、uRLLC(Ultra-Rel iableandLow-LatencyCommunications，低时延高可靠通信)业务、mMTC(massivemachinetypeofcommunication，海量机器类通信)业务进行切片)，从而满足不同类型业务需求。
不同的网络切片，提供不同类型的服务，一个网络切片构成一个虚拟网络，为UE(user equipment,用户终端)提供一种特定的移动网络接入服务；然而目前在一些情况中，终端仍然只能根据WLAN(wireless local area networks，无线局域网)网络的信号强度选择电子设备接入何种网络，过于单一，无法灵活接入特定的网络切片。

在一些实施例中，根据应用确定对应的第一接入网络，其中，第一接入网络为网络侧的多个接入网络中的一个，不同接入网络具备不同的SSID(Service Set Identifier，服 务集标识)，终端将根据应用确定出的一个接入网络作为对应的第一接入网络，需要理解的是，一个接入网络对应一个网络切片，不同的网络切片具备不同的能力；例如，网络切片具备高带宽网络能力；或，具备高清语音网络能力；或，具备低时延网络能力等，进而将不同的网络切片分为游戏网络切片、视频网络切片、固定接入网络切片、自动控制网络切片、语音通话切片等；需要理解的是，上述多个接入网络可以是具备支持多个SSID的同一网关设备或同一网络设备发出的；上述多个接入网络也可以是多个网关设备和/或多个网络设备分别发出的。
在一些实施例中，根据应用确定对应的第一接入网络包括以下任意一种：根据应用的类型确定对应的第一接入网络；根据应用的名称确定对应的第一接入网络；根据应用需要的业务质量确定对应的第一接入网络。
在一些实施例中，根据应用的类型确定对应的第一接入网络时，首先确定应用的类型，其中应用类型包括但不限于：视频类、社交应用类、游戏类、通话通讯类等；一个应用类型对应一个网络切片，也即对应一个接入网络，一个网络切片可以对应多个应用类型；例如，当应用类型为视频类，则此时根据视频类应用对业务速率的要求，获取具备高带宽网络能力的网络切片对应的接入网络作为第一接入网络；当应用类型为游戏类时，获取具备低时延网络能力的网络切片对应的接入网络作为第一接入网络；当应用类型为通话通讯类时，获取具备高清语音网络能力的网络切片对应的接入网络作为第一接入网络。
在一些实施例中，根据应用的名称确定对应的第一接入网络时，对各应用名称分别设置对应的网络切片，一个应用名称对应一个网络切片，也即对应一个接入网络，一个网络切片可以对应多个应用名称；例如，当应用名称为《Glory of Kings》，获取具备低时延网络能力的网络切片对应的接入网络作为第一接入网络。
在一些实施例中，根据应用需要的业务质量确定对应的第一接入网络时，其中业务质量包括但不限于：时延要求、带宽要求，一种业务质量对应一个网络切片，也即对应一个接入网络，一个网络切片可以对应多个业务质量；例如，当应用需要的业务质量中时延要求为低时延时，获取具备低时延网络能力的网络切片对应的接入网络作为第一接入网络。
需要立即的是，各应用对应的网络切片可以灵活改变，本实施例并不用于限制各应用对应的网络切片。
在一些实施例中，根据应用确定对应的目标接入网络之前还包括：配置应用对应的第一接入网络；例如，通过该应用的类型配置该应用对应的接入网络；通过该应用的名称配置该应用对应的接入网络；通过该应用需要的业务质量配置该应用对应的业务名称。需要理解的是，根据应用确定对应的目标接入网络之前还包括配置默认接入网络，当根据应用无法确定对应的第一接入网络时，则接入默认接入网络，终端基于该默认接入网络进行通 信。
在一些实施例中，应用启动包括但不限于：运行应用、将应用切换到前台等，例如，将未运行的应用启动、将在后台运行的应用切换到前台运行等。
S102、从第二接入网络切换到第一接入网络，通过第一接入网络进行通信；
需要理解的是，其中第二接入网络是当前用于通信的网络，其可以是上述的默认接入网络，第一接入网络与第二接入网络分别对应不同的网络切片；其中第一接入网络与第二接入网络可以是具备支持多个SSID的同一网关设备或同一网络设备发出的不同接入网络，也可以是多个网关设备和/或多个网络设备分别发出的不同接入网络。
在一些实施例中，从第二接入网络切换到第一接入网络，通过第一接入网络进行通信包括：保持第二接入网络的连接，将当前通信网络从第二接入网络切换到第一接入网络，通过第一接入网络进行通信。例如，终端确定了对应的第一接入网络后，在连接到第一接入网络时，保持与第二接入网络的连接，同时连接到了第二接入网络和第一接入网络，将当前通信网络从第二接入网络切换到第一接入网络，通过第一接入网络进行通信。
在一些实施例中，从第二接入网络切换到第一接入网络，通过第一接入网络进行通信包括：断开第二接入网络的连接，将第一接入网络作为当前通信网络，通过第一接入网络进行通信。例如，终端确定了对应的第一接入网络后，在连接到第一接入网络时，直接断开第二接入网络的连接，只连接第一接入网络，进而将第一接入网络作为当前通信网络，通过第一接入网络进行通信。
在一些实施例中，该网络切片的选择方法还包括：退出应用时，从第一接入网络切换到默认接入网络，通过默认接入网络进行通信。例如，将该应用关闭，或将该应用切换到后台运行，或是将该应用切换到后台的时间达到预设阈值等。
本申请实施例提供的网络切片的选择方法，通过当应用启动时，根据应用确定对应的第一接入网络；从第二接入网络切换到第一接入网络，通过第一接入网络进行通信；第一接入网络与第二接入网络分别对应不同的网络切片，基于应用和不同接入网络的对应关系，实现“应用->接入网络->网络切片”的对应关系，进而实现应用和网络切片的对应。实现了终端根据应用灵活选择接入网络，进而达到根据应用灵活选择网络切片的效果，避免了终端只能根据WLAN网络的信号强度选择电子设备接入何种网络，过于单一，无法灵活接入特定的网络切片的问题。
实施例二：
为了更好的理解本申请，本实施例提供一种更为具体的示例对上述网络切片的选择方法进行说明，请参见图2，图2所示为网络切片的选择方法流程示意图，其包括：
S201、网关类设备进行多切片建立；
在一些实施例中，网关类设备基于网络切片的支持，和3GPP(3rd Generation Partnership Project，第三代合作伙伴计划)核心网络交互，建立起不同的网络切片，每个网络切片对应不同的切片功能，每种切片功能对应不同的QoS(Quality of Service，服务质量)，QoS包括但不限于以下任一：高带宽网络能力，高清语音网络能力，低时延网络能力等，进而将不同的网络切片分为游戏网络切片、视频网络切片、固定接入网络切片、自动控制网络切片、语音通话切片等。
需要理解的是，在多切片建立时，还需要确认多切片是否建立成功，若多切片建立失败则将失败信息反馈给用户或管理员，其中，影响多切片建立的因素包括设备的签约情况、以及当前网络的支持情况等。
S202、网关类设备进行多SSID建立；
在一些实施例中，通过网关类设备的多SSID功能，建立与网络切片数对应数量的SSID，各SSID名称不同，例如，建立的名称可以为：“ZTE_SSID_NORMAL”、“ZTE_SSID_GAME”和“ZTE_SSID_video”等。需要理解的是。需要理解的是，在SSID建立时，还需要确认多SSID是否建立成功，若多SSID建立失败则将失败信息反馈给用户或管理员，其中，SSID支持的数目依赖于网关类设备的支持情况，支持的SSID数目越多，可以支持的网络切片数也越多。
S203、网关类设备映射各SSID到不同的网络切片；
在一些实施例中，需要通过路由表建立“SSID network interface”和“网络切片network interface”的路由对应关系，也即，通过将各个SSID映射到不同的网络切片，进行路由配置，不同的SSID体现为不同的网络端口，也即对不同的网络端口配置独立的路由；例如，将SSID“ZTE_SSID_GAME”映射到具备低时延网络能力的游戏网络切片，将SSID“ZTE_SSID_video”映射到具备高速率网络能力的视频网络切片，将“ZTE_SSID_NORMAL”映射到固定接入网络切片，同时可以将该固定接入网络切片可以作为默认网络切片，当存在应用未配置对应的网络切片、或未开启任何应用时，则将默认网络切片作为当前通信网络；需要理解的是，在映射时，还需要确认映射是否成功，若映射失败则将失败信息反馈给用户或管理员。
S204、终端配置应用对应的SSID；
在一些实施例中，终端配置应用对应的SSID包括但不限于：通过该应用的类型配置该应用对应的接入网络；通过该应用的名称配置该应用对应的接入网络；通过该应用需要的业务质量配置该应用对应的业务名称；例如，终端上存在两个应用，分别是《Glory of Kings》和《shipin》，根据应用名称《Glory of Kings》配置该应用对应的接入网络为 “ZTE_SSID_GAME”，根据应用名称《shipin》配置该应用对应的接入网络为“ZTE_SSID_VIDEO”；例如，终端设置不同应用类型对应的网络切片，当应用的类型为游戏时，配置该应用类型对应的接入网络为“ZTE_SSID_GAME”，当应用的类型为视频时，配置该应用类型对应的接入网络为“ZTE_SSID_VIDEO”，也即，当判断应用《Glory of Kings》的类型为游戏时，则该应用对应的接入网络为“ZTE_SSID_GAME”，当判断应用《Shipin》的类型为视频时，则该应用对应的接入网络为“ZTE_SSID_VIDEO”；再例如，当判断应用《Glory of Kings》需要低时延的业务质量时，则配置该应用《Glory of Kings》对应的接入网络为“ZTE_SSID_GAME”，当判断应用《shipin》需要高速率的业务质量时，则配置该应用《shipin》对应的接入网络为“ZTE_SSID_VIDEO”。进而达到具体应用通过指定网络切片进行通信的效果，例如，《Glory of Kings》->ZTE_SSID_GAME->“具备低时延网络能力的游戏网络切片”。
S205、终端在应用启动时，根据应用确定对应的SSID，并连接；
在一些实施例中，终端默认连接“ZTE_SSID_NORMAL”。终端基于该SSID进行默认通信业务，当终端运行应用《Toutiao》，由于该APP没有单独配置SSID，继续使用默认的“ZTE_SSID_NORMAL”进行通信，此时的数据流向：《Toutiao》<->ZTE_SSID_NORMAL<->“固定接入网络切片”；当终端切换应用，运行《Gloary Of Kings》，该应用启动时，检查配置了自定义SSID，触发连接应用自定义SSID也就是“ZTE_SSID_GAME”，此时的数据流向：《Glory of kings》<->ZTE_SSID_GAME<->“具备低时延网络能力的游戏网络切片”，需要理解的是，当终端存在支持多Wi-Fi连接时，则可以保持“ZTE_SSID_NORMAL”的连接，同时连接到“ZTE_SSID_GAME”，通过“ZTE_SSID_GAME”进行《Glory of kings》的通信；当终端继续切换应用，运行《shipin》，该应用启动时，检查配置了自定义SSID，触发连接应用自定义SSID也就是“ZTE_SSID_VIDEO，此时的数据流向：《shipin》<->ZTE_SSID_VIDEO<->“具备高速率业务质量的视频网络切片”；需要理解的是，各应用绑定在对应SSID对应的“网络端口”上，例如，在Linux类操作系统上可以通过socket的SO_BINDTODEVICE来实现。
S206、终端在应用关闭时，断开对应的SSID连接。
在一些实施例中，终端退出配置了SSID的应用时，触发断开配置的SSID，回到默认连接。例如，终端退出《Glory of Kings》，该应用退出时，检查配置了配置的SSID，触发断开配置的SSID也就是“ZTE_SSID_GAME”流程，并重新连接到“ZTE_SSID_NORMAL”。
在本实施例中，通过网关类设备进行多切片建立，并进行多SSID建立，最后映射各SSID到不同的网络切片，终端配置应用对应的SSID，并在应用启动时，根据应用确定对应的SSID，并连接，在应用关闭时，断开对应的SSID连接；通过网关类设备基于多个SSID 映射到不同的网络切片，实现不同SSID的对应不同的网络切片；终端基于应用和SSID的对应关系，实现“应用->SSID->网络切片”的对应关系，实现应用和网络切片的对应。实现了终端根据应用灵活选择网络切片，避免了终端只能根据WLAN网络的信号强度选择电子设备接入何种网络，过于单一，无法灵活接入特定的网络切片的问题。

本实施例中的计算机可读存储介质可用于存储一个或者多个计算机程序，其存储的一个或者多个计算机程序可被处理器执行，以实现上述实施例一和实施例二中的网络切片的选择方法的至少一个步骤。
