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详细说明。需要说明的是,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。
本发明实施例提供的标识网络方法可以应用于将业务网络根据业务特 性划分为多个分布式部署的子业务网络,多个子业务网络可能同时覆盖同一区域,为区域内的不同业务提供服务,也就是说,同一物理位置可能同时有多个子业务网络覆盖的场景下,终端初始接入时,由接入网络或终端根据终端属性、终端业务等策略决定选择接入哪个子业务网络时。本实施例提供的标识网络方法可以通过标识网络装置来执行,该标识网络装置可以集成在网络节点、接入点网元或者单独设置,其中,网络节点可以是核心网网元,如移动管理实体(Mobility Management Entity,简称MME),接入点网元可以是基站,该标识网络装置可以采用软件和/或硬件的方式来实现。以下对本实施例提供的标识网络方法及其装置进行详细地说明。
图1为本发明实施例一的标识网络方法的流程示意图,图2为本发明实施例一的标识网络方法的网络架构图,图3为本发明实施例一的标识网络方法的4G移动网络架构图。如图1所示,本发明实施例提供的标识网络方法,包括以下步骤:
步骤101、第一网络节点确定自身的网络属性标识。
在本实施例中,所述网络属性标识用于标识第一网络节点的至少一个网络能力(Network Capability,简称NC),也就是说,网络属性标识(Network Attribution,简称NA)需要保存在子业务网络的相关设备或功能实体中,用于标识本设备或本功能实体。其中,该网络能力可以是移动互联网、虚拟专用网、物联网、车联网、工业控制网络、远程医疗网络、语音业务网络、设备对设备(D2D,Device-to-Device)网络等。
如图2所示,通信网络包括业务网络1和接入网络2,其中,业务网络(也可称为业务网络层)1包括多个网络节点,即多个子业务网络11,所述多个子业务网络11用于为不同的业务提供服务。接入网络(也可称为接入网络层、接入层)2包括连接到多个子业务网络11的接入节点21,接入节点21用于从连接到的多个子业务网络11中,为终端选择一个子业务网络11接入。子业务网络11可以是一个或多个可见的物理实体,或运行在一个物理设备实体中的应用虚拟化技术实现的一个或多个软件功能实体,或运行在接入设备(例如eNodeB)物理实体中的软件功能实体。多个子业务网络11中,可以将一个(或更多)子业务网络作为缺省子业务网络。
图2中虽然示出了3个子业务网络,但子业务网络的数目可以是大于或等于2个的任意整数。虽然示出了4个接入节点21,但接入节点21的数目可以是任意正整数。图2中,虽然每一接入节点21均连接到3个子业务网络11,但这只是示例性的,接入网络2包括至少一个连接到多个子业务网络11的接入节点21即可,就单个接入节点21而言,可以只连接到业务网络1中的部分子业务网络11。
另外,每一子业务网络11均可以按区域再划分为多个局部网络,就同一区域而言,可以设置多个子业务网络11的局部网络,该区域的接入节点21与多个子业务网络11在该区域的局部网络连接。也就是说,该多个子业务网络11同时覆盖这一区域,为该区域内的不同业务提供服务。
本实施例的业务网络1可以是移动网络架构如第二代移动通信技术(2G)、第三代移动通信技术(3G)、第四代移动通信技术(4G)中的核心网(CN:Core Network),该移动网络架构中的核心网包括多个子业务网络11,为不同的业务提供服务,这里,不同的子业务网络11服务的业务可以有重叠,如可以设定一个缺省的子业务网络,该缺省子业务网络可以为多种业务提供服务。在该移动网络架构中,接入节点包括移动网络架构中的基站,如BS(Base Station)、NodeB、eNodeB(evolved Node B)等,也可以是其他具有接入功能的接入节点如中继站、接入点(AP,Access Point)等。但本申请不局限于移动网络架构,例如,业务网络1也可以是下一代网络中为终端提供网络连接服务的功能实体。
图3所示是本实施例通信网络基于4G移动网络架构实现时的一种示例性的网络架构。在该示例中,根据业务的特性和要求,将演进分组核心网(EPC:Evolved Packet Core)按业务特性差异化部署,划分成多个子业务网络(也可称为子EPC网络、子核心网)。图3中包含MME和SAE-GW(System Architecture Evolution-Gateway)的每一椭圆表示一个子业务网络的一局部网络,分别用EPC1~5标志,仅作为示例地,图3中的EPC1和EPC4同属于一子业务网络,专为VoLTE(Voice over LTE)语音服务;EPC2和EPC5同属于另一子业务网络,专用于物联网终端;EPC3属于又一子业务网络,专用于车联网终端。接入节点eNodeB可以同时与两个或三个子业 务网络的局部网络相连接。
步骤102、第一网络节点向至少一个接入节点发送所述网络属性标识,所述第一网络节点与所述至少一个接入节点连接。
在本实施例中,第一网络节点确定自身的网络属性标识,所述网络属性标识用于标识第一网络节点的至少一个网络能力;所述第一网络节点向至少一个接入节点发送所述网络属性标识,所述第一网络节点与所述至少一个接入节点连接。如此,实现了接入节点对网络节点对应的网络能力的识别,从而可以灵活地选择适合终端接入的子业务网络。
在上述实施例的基础上,适用场景为:终端初始附着,由终端选择子业务网络(即网络节点)时,所述第一网络节点向接入节点发送所述网络属性标识之后,所述方法还可以包括:
所述第一网络节点接收所述终端通过第一接入节点发送的第二附着请求消息,所述第二附着请求消息携带所述终端请求的或所述第一接入节点确定的第一网络节点标识和第一网络属性标识;
所述第一网络节点通过所述第一接入节点向所述终端发送第二附着接受消息,所述第二附着接受消息携带所述第一网络节点为所述终端新分配的临时标识、所述第一网络节点标识和所述第一网络属性标识,所述临时标识包括所述第一网络节点为所述终端分配的标识。
可选地,在上述实施例的基础上,该方法还可以包括:
所述网络节点接收所述终端通过第二接入节点发送的位置更新请求消息,所述位置更新请求消息携带所述第一网络节点标识和所述第一网络属性标识,所述第二接入节点包括终端当前连接的接入节点,所述第一网络节点标识包括所述终端在连接到所述第二接入节点之前最近一次连接的网络节点的标识,所述第一网络属性标识包括所述第一网络节点标识指示的网络节点的网络属性标识,所述第一网络节点分别与所述第一接入节点和所述第二接入节点连接;
所述第一网络节点通过所述第二接入节点向所述终端发送位置更新接受消息,所述位置更新接受消息携带所述第一网络节点为所述终端新分配 的临时标识、所述第一网络节点标识和所述第一网络属性标识。
可选地,在上述实施例的基础上,适用场景为:终端处于连接态发生位置改变时,源侧子业务网络根据第一网络属性标识选择目标侧子业务网络时,该方法还可以包括:
所述第一网络节点接收第一接入节点发送的切换请求消息,所述切换请求消息携带目标接入节点标识、所述第一网络节点标识和所述第一网络属性标识,所述第一网络节点标识包括所述终端当前连接的网络节点的标识,所述第一网络属性标识包括所述第一网络节点标识指示的网络节点的网络属性标识,所述目标接入节点标识包括所述第一接入节点请求切换到的目标接入节点的标识;
所述第一网络节点根据所述目标接入节点标识和所述第一网络属性标识,确定目标网络节点,所述目标网络节点的网络能力与所述第一网络属性标识指示的网络能力相同;
所述第一网络节点向所述目标网络节点发送前转重定位请求消息,所述前转重定位请求消息携带所述第一网络节点标识和所述第一网络属性标识。
需要说明的是,当所述第一网络节点与所述目标接入节点有连接时,所述目标网络节点即为所述第一网络节点,则不存在前转重定位请求消息。
在上述实施例的基础上,所述网络属性标识为独立标识,或者,所述网络属性标识设置在PLMN标识中。
举例来讲,网络属性标识设置在PLMN标识中的实现方式包括:扩展PLMN标识作为子业务网络的NC。
其中,可以为子业务网络扩展PLMN标识,从而实现标识子业务网络的能力或属性。
扩展PLMN号码为PLMN-Ext=MCC(Mobile Country Code,移动国家码)+MNC(Mobile Network Code,移动网络码)+NC(Network Capability),NC标识子业务网络的能力或属性。
PLMN-Ext标识可以由基站广播给终端,终端可以根据终端属性或业务选择匹配的PLMN-Ext接入。
子业务网络的移动性管理实体的设备标识扩展为:
<GUMMEI’>=<MCC><MNC><NC><MME Identifier>
MME分配的终端临时标识(GUTI,Globally Unique Temporary UE Identity)扩展为:
<GUTI’>=<GUMMEI’><M-TMSI>
基站标识、位置区域等虽然也用PLMN作为标识的一部分,但是基站和位置区域的部署是与子业务网络能力或属性无关的,因此基站和位置区域的标识不需要扩展。
举例来讲,所述网络属性标识设置在所述临时标识中的实现方式包括:扩展独立字段作为子业务网络的NC。
以相关的网络架构为例,可以为子业务网络增加一个NC标识,从而实现标识子业务网络的能力或属性。
NC标识和子业务网络的PLMN一起,由基站广播给终端,终端可以根据终端属性或业务选择合适的子业务网络,在发起接入时将所选择的PLMN和对应的NC通知给基站。
MME为终端分配的GUTI扩展为:
<GUTI’>=<GUMMEI><NC><M-TMSI>。
