图1是根据一示例性实施例示出的一种网络切片的使用方法的流程图,图2是根据一示例性实施例示出的一种网络切片的使用方法的应用场景图;该网络切片的使用方法可以应用在基站上,如图1所示,该网络切片的使用方法可以包括以下步骤110-130:
在步骤110中,确定自身能够支持的一个或多个第一网络切片。
本公开实施例中,第一网络切片指的是基站能够支持的网络切片。比如:基站能够支持的网络切片包括网络切片1和网络切片2。
在步骤120中,生成第一网络切片信息,该第一网络切片信息用于表征各个第一网络切片。
本公开实施例中,基站可以通过第一网络切片信息将自身能够支持的各个第一网络切片告知终端。
在一实施例中,第一网络切片信息包括S-NSSAI(Single Network Slice Selection Assistance Information,单一网络切片选择辅助信息)列表,所述S-NSSAI列表中包括用于标识所述第一网络切片的网络切片标识。其中,每个S-NSSAI用于标识一个网络切片。
比如:基站能够支持的网络切片包括网络切片1和网络切片2,S-NSSAI表中用于标识网络切片1的网络切片标识为1,S-NSSAI表中用于标识网络切片2的网络切片标识为2。
在步骤130中,将第一网络切片信息发送至终端,以使终端根据第一网络切片信息确定基站能够支持的各个第一网络切片。
在一实施例中,执行步骤130时,基站可以通过系统消息将第一网络切片信息发送至终端,其具体过程包括:
(1-1)将所述第一网络切片信息添加到系统消息中;
(1-2)将所述系统消息发送至所述终端,以使所述终端从所述系统消息获取所述第一网络切片信息。
在一实施例中,上述(1-1)中的系统消息可以包括但不限于以下至少一项:
(2-1)MIB(Master Information Block,主信息块);
(2-2)SIB1(System Information Block,系统信息块);
(2-3)指定信息块,所述指定信息块是所述基站为了承载所述网络切片信息而专门建立的一个信息块。
在一实例性场景中,如图2所示,包括基站和终端。基站在确定自身能够支持的一个或多个第一网络切片后,可以生成第一网络切片信息,该第一网络切片信息用于表征各个第一网络切片,以及将第一网络切片信息发送至终端,这样终端就可以根据第一网络切片信息确定述基站能够支持的各个第一网络切片。
由上述实施例可见,在确定自身能够支持的一个或多个第一网络切片后,基站可以生成第一网络切片信息,该第一网络切片信息用于表征各个第一网络切片,以及将第一网络切片信息发送至终端,这样终端就可以根据第一网络切片信息确定述基站能够支持的各个第一网络切片,从而提高了网络切片使用的可靠性。
图3是根据一示例性实施例示出的另一种网络切片的使用方法的流程图,该网络切片的使用方法可以应用在基站上,并建立图1所示方法的基础上,在执行步骤130之后,如图3所示,该网络切片的使用方法还可以包括以下步骤310-340:
在步骤310中,接收终端发送的第二网络切片信息,该第二网络切片信息用于表征第三网络切片,该第三网络切片是终端需要的一个或多个第二网络切片中、与第一网络切片匹配的网络切片。
本公开实施例中,基站在将自身能够支持的各个第一网络切片告知终端后,终端还会判断自身需要的一个或多个第二网络切片中是否存在与第一网络切片匹配的第三网络切片,若存在,终端就会将第三网络切片告知基站;若不存在,终端就不会将自身需要的第二网络切片告知基站。其中,判断是否存在与第一网络切片匹配的第三网络切片的方法,就是判断第三网络切片是否是基站能够支持的,若能支持,就是匹配;若不能支持,就是不匹配。
比如:基站能够支持的各个第一网络切片包括网络切片1和网络切片2,而终端需要的第二网络切片中包括网络切片1,则确定基站能够支持网络切片1,即表明网络切片1片与第一网络切片匹配,这时终端就会将网络切片1告知基站。
又比如:基站能够支持的各个第一网络切片包括网络切片1和网络切片2,而终端需要的第二网络切片中包括网络切片3,则确定基站不能够支持网络切片3,即表明网络切片3与第一网络切片不匹配,这时终端就不需要将网络切片3告知基站。
又比如:基站能够支持的各个第一网络切片包括网络切片1和网络切片2,而终端需要的第二网络切片中包括网络切片1和网络切片3,则确定基站能够支持网络切片1、但不能够支持网络切片3,即表明网络切片1片与第一网络切片匹配、但网络切片3与第一网络切片不匹配,这时终端只需要将网络切片1告知基站、而网络切片3就不需要告知基站了。
在步骤320中,当需要为终端选择AMF(Access and Mobility Management Function,接入和移动管理功能)时,则根据第三网络切片为终端选择对应的第一AMF。
本公开实施例中,AMF是核心网的一个功能,并通过AMF名称来识别不同的AMF。并且,根据运营商的配置,每个AMF都会有能够服务的网络切片,如果终端需要网络切片1,那么基站会选择能够服务网络切片1的AMF进行连接。其中,一个AMF可能服务多个网络切片;同理,一个网络切片也可能存在多个可能服务的AMF。
在步骤330中,生成第一指示信息,该第一指示信息用于表征第一AMF。
本公开实施例中,基站可以通过第一指示信息将为终端选择的到底是哪个AMF告知终端。
在步骤340中,将第一指示信息发送至终端,以使终端根据该第一指示信息确定第一AMF。
在一实施例中,执行步骤340时,基站可以通过RRC(Radio Resource Control,无线资源控制)建立完成信令将第一指示信息发送至终端,其具体过程包括:
(3-1)将所述第一指示信息添加到RRC建立完成信令中;
(3-2)将所述RRC建立完成信令发送至所述终端,以使所述终端从所述RRC建立完成信令获取所述第一指示信息。
由上述实施例可见,当接收到终端发送的第二网络切片信息时,可以根据第二网络切片为终端选择对应的第一AMF,并生成第一指示信息,该第一指示信息用于表征第一AMF,以及将第一指示信息发送至终端,这样终端就可以根据该第一指示信息确定第一AMF,从而实现了基站根据终端的需求为该终端选择对应的AMF这一功能, 还提高了AMF选择的准确性。
图4是根据一示例性实施例示出的另一种网络切片的使用方法的流程图,该省网络切片的使用方法可以应用在基站上,并建立图1所示方法的基础上,在执行步骤130之后,如图4所示,该网络切片的使用方法还可以包括以下步骤410-430:
在步骤410中,当需要为终端选择AMF时,为终端选择默认的第二AMF。
本公开实施例中,若基站没有接收到终端上报的自身需要的第二网络切片、或终端没有上报自身需要的第二网络切片的机制、或由于第二网络切片与第一网络切片不匹配而导致的终端不需要上报自身需要的第二网络切片等,此时基站就可以为终端选择默认的第二AMF。其中,第二AMF可以是运营商设定的一个默认AMF。
在步骤420中,生成第二指示信息,该第二指示信息用于表征第二AMF;
本公开实施例中,基站可以通过第二指示信息将为终端选择的到底是哪个默认AMF告知终端。
在步骤430中,将第二指示信息发送至终端,以使终端根据该第二指示信息确定第二AMF。
本公开实施例中,基站也可以通过RRC建立完成信令将第二指示信息发送至终端。具体过程可以参照通过RRC建立完成信令将第一指示信息发送至终端的过程,在此不再赘述。
由上述实施例可见,当需要为终端选择AMF时,还可以为终端选择默认的第二AMF,并生成第二指示信息,该第二指示信息用于表征所述第二AMF,以及将第二指示信息发送至终端,这样终端就可以根据该第二指示信息确定第二AMF,从而满足了不同AMF配置场景的需求,还提高了AMF配置的实用性。

由上述实施例可见,通过接收基站发送的第一网络切片信息,该第一网络切片信息用于表征基站能够支持的一个或多个第一网络切片,并根据第一网络切片信息确定基站能够支持的各个第一网络切片,从而提高了网络切片使用的可靠性。

在步骤620中,判断第二网络切片是否存在与第一网络切片匹配的第三网络切片;若存在,则执行步骤630;若不存在,则执行步骤640。
本公开实施例中,判断第三网络切片与第一网络切片是否匹配的方法,就是判 断第三网络切片是否是基站能够支持的,若能支持,就是匹配;若不能支持,就是不匹配。
比如:基站能够支持的各个第一网络切片包括网络切片1和网络切片2,而终端需要的第二网络切片中包括网络切片1,则确定基站能够支持网络切片1,即表明网络切片1片与第一网络切片匹配,这时终端就会将网络切片1告知基站。
又比如:基站能够支持的各个第一网络切片包括网络切片1和网络切片2,而终端需要的第二网络切片中包括网络切片3,则确定基站不能够支持网络切片3,即表明网络切片3第二网络切片与第一网络切片不匹配,这时终端就不需要将自身需要的网络切片3告知基站。
在步骤630中,生成第二网络切片信息,该第二网络切片信息用于表征各个第三网络切片,并将第二网络切片信息发送至基站,以使基站根据第二网络切片信息确定各个第三网络切片。
