具体实施方式
这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
相关技术中,提出了一种新的网络资源划分方式,即网络切片(network slicing)。每个网络切片承载一定类型的业务或服务。在网络切片上,通过PRACH(Physical Random Access Channel,物理随机接入信道)实现小区接入。通过什么系统消息来携带网络切片的PRACH配置信息,尚未有明确规定。
相关技术提出了新的系统消息,系统消息包括最小系统消息(minimum SI,minimum System Information)和其它系统消息(other SI,other System Information)。最小系统消息和其它系统消息如何携带网络切片的PRACH配置信息,尚未有明确规定。
最小系统消息携带所有的网络切片的PRACH配置信息。但是最小系统消息的长度较小,可能无法携带所有的网络切片的PRACH配置信息。
为解决上述问题,本实施例中通过最小系统消息携带网络切片的指示信息,即一个或多个网络切片的相应PRACH配置信息存在于其它系统消息中的指示信息;通过其它系统消息携带网络切片的PRACH配置信息。用户设备通过最小系统消息获知网络切片的PRACH配置信息是否存在于其它系统消息中,如果存在于其它系统消息中,则获取其它系统消息,以获取网络切片的PRACH配置信息,完成小区接入。
图1是根据一示例性实施例示出的一种关于网络切片的接入方法的流程图,该关于网络切片的接入方法用于网络侧,其中,网络侧的设备可以是基站等接入网设备。如图1所示,该方法包括以下步骤101-102。
在步骤101中,生成最小系统消息,所述最小系统消息包括以下两项:
i)一个或多个网络切片的相应PRACH配置信息存在于其它系统消息中的指示信息,
ii)公共随机接入信道配置信息;
在步骤102中,向用户设备发送所述最小系统消息。
本实施例中最小系统消息还可以包括小区选择与接入的相关信息和其它系统消息的调度信息等。
本实施例中最小系统消息包括了网络切片的指示信息,该指示信息用于指示网络切片的相应PRACH配置信息是否会在其它系统消息中携带。用户设备根据该指示信息,便可确 定本地业务对应的网络切片的PRACH配置信息是否会在其它系统消息中,如果在其它系统消息中,则获取相应的其它系统消息,以获取本地业务对应的网络切片的PRACH配置信息;如果不在其它系统消息中,则获取最小系统消息中的公共随机接入信道配置信息,通过公共随机接入信道完成小区接入。
在一个实施例中,所述一个或多个网络切片的相应PRACH配置信息存在于其它系统消息中的指示信息包括:
相应PRACH配置信息存在于其它系统消息中的一个或多个网络切片分别的网络切片标识信息。
如图2所示,最小系统消息包括网络切片标识信息时的消息结构。一个网络切片标识占用一个字段。可以有一个或多个网络切片标识。这里有多种实现方式,方式1:最小系统消息可以携带在其它系统消息中配置了网络切片的相应PRACH配置信息的网络切片标识。未在其它系统消息中配置了网络切片的相应PRACH配置信息的网络切片标识,则被缺省,不占用字段。方式2:最小系统消息携带了所有网络切片的网络切片标识。如果在其它系统消息中配置了网络切片的相应PRACH配置信息,则相应的网络切片标识所在字段有表示已经配置相应PRACH配置信息的取值。如果在其它系统消息中未配置网络切片的相应PRACH配置信息,则相应的网络切片标识所在字段有表示未配置相应PRACH配置信息的取值,或者字段为空。
通信系统预先配置有网络切片标识信息与其它系统消息编号的对应关系。网络侧和用户设备均保存有该对应关系。最小系统消息可以不包括其它系统消息编号。当最小系统消息包括的网络切片标识在其它系统消息中携带有网络切片的相应PRACH配置信息时,用户设备可以通过该对应关系确定该网络切片标识对应的其它系统消息编号。通过该其它系统消息编号获取相应的其它系统消息,以获取网络切片的相应PRACH配置信息,完成小区接入。
或者,通信系统预先配置有其它系统消息编号的顺序,如其它系统消息编号3、其它系统消息编号1和其它系统消息编号2这样的一个顺序。用户设备通过最小系统消息携带的网络切片标识信息确定网络侧将会在其它系统消息中携带所需的网络切片的相应PRACH配置信息,则用户设备先获取其它系统消息编号3的其它系统消息,查看是否有所需的网络切片的相应PRACH配置信息,如果有,则获取所需的网络切片的相应PRACH配置信息;如果没有,则用户设备获取其它系统消息编号1的其它系统消息,以此类推。
在一个实施例中,网络切片标识包括网络切片标志位信息或网络切片的编号信息。
如图3所示,最小系统消息包括网络切片标志位信息时的消息结构。一个网络切片标志位信息占用1bit。即网络切片标识对应的字段长度为1bit。最小系统消息中各网络切片标志位信息的顺序对应预设的网络切片的顺序,如最小系统消息中的第一个网络切片标志位信息对应网络切片1,以此类推。用户设备根据该顺序,可获知网络切片标志位信息对应的网络切片。例如,网络切片标志位信息的取值为1时,表示对应的网络切片的相应PRACH 配置信息存在于其它系统消息中。网络切片标志位信息的取值为0时,表示对应的网络切片的相应PRACH配置信息不存在于其它系统消息中。
如图4所示,最小系统消息包括网络切片的编号信息时的消息结构。一个网络切片的编号信息可能占用多个比特位,视网络切片的编号信息的长度而定。即网络切片标识对应的字段长度为多个比特。最小系统消息中各网络切片的编号信息可以有预设的顺序,也可以没有预设的顺序。因为用户设备根据网络切片的编号信息便可知道对应是哪个网络切片。为了节省消息长度,最小系统消息携带的网络切片的编号信息可以是存在于其它系统消息中的PRACH配置信息所对应的网络切片的编号信息。不存在于其它系统消息中的PRACH配置信息所对应的网络切片的编号信息,最小系统消息可以不携带。当然,最小系统消息可以携带所有网络切片的编号信息,则与图3所示的方案结合,最小系统消息还包括网络切片标志位信息。
在一个实施例中,所述网络切片标识信息包括网络切片的单一网络切片标识信息或组网络切片标识信息。
单一网络切片标识信息是指一个网络切片标识信息标识一个网络切片。组网络切片标识信息是指一个网络切片标识信息标识一组网络切片,一组网络切片对应一个或多个网络切片。其中,可以预先对网络切片进行分组,网络侧和用户设备均保存该分组信息。采用组网络切片标识信息可以节省最小系统消息的长度。
在一个实施例中,所述一个或多个网络切片的相应PRACH配置信息存在于其它系统消息中的指示信息还包括:
至少一个网络切片相应PRACH配置信息在其它系统消息中的其它系统消息编号。
如图5所示,最小系统消息既包括网络切片标识信息又包括相应的其它系统消息编号。通过最小系统消息的结构,体现出网络切片标识信息与其它系统消息编号的对应关系。图5示出了一种实现方式,其它实现方式也适用于本实施例。以图5为例,一个或多个网络切片标识信息的后面有一个其它系统消息编号,相当于其它系统消息编号之前的连续的网络切片标识信息均对应该其它系统消息编号。如果最小系统消息携带一个其它系统消息编号,则说明最小系统消息携带的网络切片标识信息均对应该其它系统消息编号。如果最小系统消息携带多个其它系统消息编号,则每个其它系统消息编号之前的连续的网络切片标识信息对应该其它系统消息编号。
如果网络切片标识信息为单一网络切片标识信息,则存在其它系统消息编号与网络切片的对应关系。如果网络切片标识信息为组网络切片标识信息,则存在其它系统消息编号与网络切片的分组的对应关系。
图6是根据一示例性实施例示出的一种关于网络切片的接入方法的流程图,该关于网络切片的接入方法用于网络侧,其中,网络侧的设备可以是基站等接入网设备。如图1所示,该方法包括以下步骤601-602。
在步骤601中,生成其它系统消息,所述其它系统消息包括网络切片对应的PRACH配 置信息。该网络切片为最小系统消息中的指示信息所指示的网络切片。
在步骤602中,向用户设备发送所述其它系统消息。
网络侧可以在收到用户设备的请求后,向发送请求的用户设备发送其它系统消息。或者,网络侧可以广播其它系统消息,即向多个用户设备发送其它系统消息。
在一个实施例中,所述其它系统消息还包括下一个其它系统消息编号或下一个其它系统消息的存在标志。
最小系统消息可能携带了其它系统消息编号,也可能未携带其它系统消息编号。不论哪种情况,都可能存在一个其它系统消息无法携带最小系统消息所指示的所有网络切片的相应PRACH配置信息。因此,其它系统消息还包括下一个其它系统消息编号或下一个其它系统消息的存在标志。如果用户设备在该其它系统消息中未获得本地所需的网络切片的相应PRACH配置信息,则根据该下一个其它系统消息编号获取相应的其它系统消息,以便获得本地所需的网络切片的相应PRACH配置信息。如果其它系统消息携带了下一个其它系统消息的存在标志,在该存在标志的取值(如取值为1)表示下一个其它系统消息携带有网络切片的相应PRACH配置信息时,用户设备可以预先配置的其它系统消息的编号顺序,获取下一个其它系统消息,以便获得本地所需的网络切片的相应PRACH配置信息。如果其它系统消息未携带下一个其它系统消息编号,或者存在标志的取值(如取值为0)表示下一个其它系统消息未携带有网络切片的相应PRACH配置信息,则用户设备获得最小系统消息中的公共随机接入信道配置信息,根据所述公共随机接入信道配置信息对该网络切片进行接入,即完成小区接入。

网络侧可以广播其它系统消息,例如网络侧确定小区内多个用户设备需要接收其它系统消息,便可以采用广播方式。用户设备根据最小系统消息中的其它系统消息的调度信息获取广播的其它系统消息。

如图3所示,网络切片标识包括网络切片标志位信息。用户设备根据已知的网络切片标志位信息的顺序,确定本地所需的网络切片对应的网络切片标志位信息。该网络切片标志位信息的取值表示本地所需的网络切片相应的PRACH配置信息存在于其它系统消息中时,用户设备根据预设的网络切片的编号信息与其它系统消息编号的对应关系,确定本地所需的网络切片对应的其它系统消息编号。并从最小系统消息中获取该其它系统消息编号对应的其它系统消息的调度信息。根据该调度信息获取其它系统消息。
如图4所示,网络切片标识包括网络切片的编号信息。用户设备判断最小系统消息中的网络切片的编号信息是否包括本地所需的网络切片的编号信息,如果包括本地所需的网络切片的编号信息,则根据预设的网络切片的编号信息与其它系统消息编号的对应关系,确定本地所需的网络切片对应的其它系统消息编号。并从最小系统消息中获取该其它系统消息编号对应的其它系统消息的调度信息。根据该调度信息获取其它系统消息。
