进一步地,所述接入网网元32,还用于生成终端、用户和/或会话的信息与切片业务之间的映射关系。
进一步地,所述终端、用户和/或会话的信息包括以下至少一种:用户标识、切片标识、服务质量标识、会话标识、承载标识、服务质量类型、用户能力等级。
进一步地,
所述管理网络切片的设备31,还用于向核心网网元发送策略信息和/或策略请求信息;接收所述核心网网元返回的策略许可。
进一步地,所述接入网网元32,还用于在用户终端的上下文中添加切片标签或辅助信息,以执行切片业务处理。
本公开实施例中,管理网络切片的设备31承载了4G片相关功能,包括切片相关的标识和策略配置、配置开关、更新等,具体的策略包括基于标签的路由(包括核心网选择)、辅助计费(辅助流量统计,以及面向计费单元进行信息汇报)等。如图3所示,管理网络切片的设备31与核心网网元(CN) 以及接入网网元(RAN)32均进行交互,管理网络切片的设备31将更新后的策略配置发给接入网网元32和核心网网元,接入网网元32反馈给管理网络切片的设备31监控信息,核心网网元与管理网络切片的设备31进行策略许可计费交互。
本实施例的管理网络切片的设备31不仅能够支持4G化的端到端网络切片、也能够支持4G演进切片和支持5G切片,另外管理网络切片的设备31还负责指标输出、指标开放,以及网络其他能力的开放。
如图4所示,以接入网网元为基站为例,在管理网络切片的过程中,包括以下步骤:
步骤a、第三方34和管理网络切片的设备31完成策略定制,包括监控需求;
步骤b、基站32向管理网络切片的设备31定期或者不定期提供监控信息;
步骤c、管理网络切片的设备31基于监控信息以及策略需求,制定对应的基站策略,分发给基站进行执行,所述的策略包含,策略目标对象和策略执行方法或者根据;具体地,所述的策略目标对象为用户或者应用的标签,包括不限于IP五元组各个维度信息,用户网络标识,服务质量类型识别符。所述的策略包括针对本地分流等,以及执行策略所需要的信息;所述策略可能包含调度优先等。
比如,策略目标对象为某垂直客户(如果能够基于用户标签确定一客户,那么在连接的时候就确定下来,不需要额外的复杂度);策略执行方法为:本地分流到目标APN;如果是某个垂直客户+特定业务来做标签,可以通过建设不同的DRB来解决,即使这两个DRB具有相同的服务质量类型识别符,目前在LTE中有若干预留使用的服务质量类型识别符,可以供运营商进行定制使用。
步骤d、用户终端33和基站32完成连接建立。基站32随后基于连接信息,建立了表征策略、表征用户标签的信息的映射关系,以供后续数据传输识别时进行策略执行。具体地,基站侧存储了一个映射表(mapping table),可能包含的信息具体包括:slice value,UE ID,服务质量类型识别符,其中 UE ID和服务质量类型识别符可能同时包含,或者只包含一个;这样就不需要针对每个数据包做解析,即可完成差异化的优化;
步骤e、用户终端33进行数据传输,基站32基于所述的标签识别数据,并执行策略。基站32基于对应数据对应的切片(slice)ID,UE ID以及,或者服务质量类型识别符ID,执行对应的无线网络优化
步骤f、基站32与管理网络切片的设备31进行策略更新,包括策略开关。
本公开的技术方案中,管理网络切片的设备31可以由基站附近的移动边缘计算(Mobile Edge Computing,MEC)或者网络管理单元来承载,或者在未来的集中单元分布单元(CUDU)两级接入网络架构上,和集中单元(CU)共享平台。该管理网络切片的设备31承载切片网管功能,处理切片相关的移动性,以及可能地,可以屏蔽核心网对无线接入网(Radio Access Network,RAN)专属切片的感知。除了核心网控制,管理网络切片的设备31也可以集成一定的核心网网络的控制,比如本地分流和转发;比如服务质量类型识别符策略协商、本地分流和计费协商等。
本公开的技术方案中,允许基站与管理网络切片的设备31交互,确定邻近站点的虚拟切片支持能力,还允许基站之间在UE的上下文中添加切片标签或者相关辅助信息。本实施例中,将5G切片4G化,基于管理网络切片的设备的网管功能,做对应虚拟切片(virtual slice)的标签、标签对应的配置(profile)以及策略(policy),同时基站、核心网均能与管理网络切片的设备交互,如图5所示,管理网络切片的设备将策略告知给核心网网元,核心网网元向管理网络切片的设备进行计费开放。
本公开实施例还提供一种接入网网元,包括存储器、处理器及存储在存储器上并可在处理器上运行的计算机程序,其中,所述处理器执行所述计算机程序时实现上述接入网网元执行的管理网络切片的方法的步骤。
本公开实施例还提供一种切片管理设备,包括存储器、处理器及存储在存储器上并可在处理器上运行的计算机程序,其中,所述处理器执行所述计算机程序时实现上述由切片管理设备执行的管理网络切片的方法的步骤。

以上所述是本公开的可选的实施方式,应当指出,对于本技术领域的普通技术人员来说,在不脱离本公开所述原理的前提下,还可以作出若干改进和润饰,这些改进和润饰也应视为本公开的保护范围。
