具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。
为解决相关技术存在的代理Proxy只能手动配置在NF上,无法进行动态更新,缺乏可扩展性,而且在多Proxy部署时,会带来复杂的路由选择问题的技术问题,本公开实施例提供一种代理的通信方法,采用该通信方法,代理实体能够自主在NRF上进行注册、更新和/或去注册,实现Proxy自主在网络存储功能上的注册和路由选择,而无需相关技术中的手动配置,达到节省大量人力成本的效果。
本公开其中一实施例所述代理的通信方法,应用于代理实体,如图1所示,包括:
S110,向网络存储功能实体发送管理请求;
其中,所述管理请求包括注册请求、配置更新请求和去注册请求的至少之一。
可选地,所述管理请求为注册请求、配置更新请求和去注册请求中的其中之一。
可选地,所述管理请求也可以包括注册请求、配置更新请求和去注册请求,在注册请求、配置更新请求和去注册请求时,所述代理实体向网络存储功能NRF实体发送注册请求之后,还包括向网络存储功能实体发送配置更新请求和/或去注册请求的步骤。

方式一,通过网络功能NF管理服务,向网络存储功能实体发送所述管理请求;
方式二,通过代理管理服务,向网络存储功能实体发送所述管理请求。
其中,在通过方式一,向网络存储功能实体发送管理请求时,代理实体被等效为服务为空的NF,通过NF管理服务,向NRF发送管理请求;
在通过方式二,向网络存储功能实体发送管理请求时,为Proxy定义新的NRF服务,也即代理管理服务,用于Proxy的注册、更新和/或去注册。
以下对步骤S110中,代理实体分别向网络存储功能实体发送注册请求、配置更新请求和去注册请求的具体方式进行详细说明。
需要说明的是,本公开实施例中的代理实体包括并不限于仅能够包括SCP和/或SEPP,为清楚说明本公开实施例所述通信方法的具体过程,以下将以所述代理实体为SCP对本公开的具体方案进行说明,但可以理解的是,所述通信方法并不限于仅能够应用于SCP的注册、更新和去注册等,其他代理实体采用本公开实施例所述通信方法,也应属于本公开的保护范围之内。
实施方式一
在步骤110,代理实体通过方式一向网络存储功能实体发送注册请求。
采用该方式,代理实体如可以为SCP,在入网时,将被等效看作为一个服务为空的NF,和其他NF一样,需要利用NF管理的NF注册请求在NRF进行信息注册。
具体地,如图2所示,代理实体发送注册请求的过程包括:
S1111,Proxy向NRF发送NF管理的NF注册请求,也即步骤S110中的管理请求;
其中,可选地,该NF注册请求中包括代理类型、实例标识ID、公共陆地移动网(Public Land Mobile Network,PLMN)标识ID、地址信息、配置能力、所提供代理的功能信息、所在网络的网络状况信息和周边可服务网络实体的实体信息。
其中,NF管理的NF注册请求中:
NF类型字段记录所述代理实体的代理类型;
NF实例标识ID字段记录所述代理实体的实例标识ID;
NF所提供网络功能的服务信息的名称字段记录为空;以及
还包括增加字段,用于分别记录所提供代理的功能信息、所在网络的网络状况信息和周边可服务网络实体的实体信息。
具体地,代理类型为SCP时,NF类型字段相较于相关技术新增定义为“SCP”,以能够用于记录代理实体的代理类型;另外,通过NF实例标识ID字段记录代理实体的实例标识ID、NF所提供网络功能的服务信息的名称字段记录为空和NF的PLMN标识ID记录代理实体的PLMN标识ID,并将该些字段信息通过NF注册请求上报至NRF,以使代理实体注册自己的NF配置Profile。
另外,同其他NF一样,NF注册请求中还包括地址信息和配置能力,以能够用于路由选择;其中该地址信息包括但并不限于仅能够包括IP地址和绝对域名(Fully Qualified Domain Name,FQDN)等地址信息;该配置能力包括并不限于仅能够包括优先权priority、容量capacity、负荷、地区locality和服务范围ServingScope等。
此外,采用本公开实施例所述通信方法,NF注册请求中还包括增加字段,用于分别记录所提供代理的功能信息、所在网络的网络状况信息和周边可服务网络实体的实体信息。其中,所提供代理的功能信息,如为间接通信或委托发现等;所在网络的网络状况信息包括带宽、速率、时延、缓存buffer和消息排队情况;周边可服务网络实体的实体信息,该实体信息可以包括NF和/或Proxy。
可选地,本公开实施例中,在Proxy入网注册时,也即在代理实体发送的注册请求中,周边可服务网络实体的实体信息记录为空,或者记录为预设 配置值,该预设配置值可以表示proxy计划服务的NF和/或Proxy。
进一步,可选地,该周边可服务网络实体的实体信息可在代理实体获得周边网络实体信息后进行动态更新。具体地,代理实体可以通过查询NRF或订阅状态通知,获得最新的周边可服务的NF和/或Proxy,并添加至“该周边可服务网络实体的实体信息”的参数中,并进一步将该参数值通过配置更新请求,更新至NRF上,以能够在NRF上维护该参数的最新值,以供其他NF或Proxy使用。该具体过程将在以下的内容中进行详细说明。
可选地,采用本公开实施例所述通信方法,代理实体也可以向NRF发送NF管理的NF状态订阅请求,注册NRF的其他服务。
在实施方式一中,如图2所示,在步骤S1111,Proxy向NRF发送NF管理的NF注册请求之后,所述方法还包括:
S1112,NRF存储NF配置,也即存储注册请求中代理实体的配置信息;
S1113,NRF向Proxy发送NF管理的NF注册响应。
利用上述的过程,Proxy通过调用网络功能NF管理服务,能够完成Proxy在NRF上的注册。
实施方式二
在步骤S110,代理实体通过方式一向网络存储功能实体配置更新请求。
采用该实施方式,在代理实体如为SCP,入网后,自身信息有更新时,将被等效看作为一个服务service为空的NF,和其他NF一样,需要去NRF更新本身的配置信息,如可通过现有NF管理的NF更新服务,将本身的NF实例ID上报至NRF,用于更新本身的NF配置。具体实现流程图3所示,包括:
S1121,Proxy向NRF发送NF管理的NF更新请求,也即步骤S110中的管理请求,该NF更新请求中包括NF实例ID,用于对应记录代理实体的实例ID;以及还包括所需要更新的配置信息;
S1122,NRF对NF更新请求中代理实体的相应配置信息进行更新;
S1123,NRF向Proxy发送NF管理的NF更新响应。
可选地,在步骤S1121中,Proxy所需要更新的配置信息可以包括周边可服务网络实体的实体信息,通过将该实体信息更新至NRF,以能够在NRF 上始终维护该参数的最新值,供其他NF或Proxy使用。
利用上述的过程,Proxy通过调用网络功能NF管理服务,能够完成Proxy在NRF上的配置更新。
实施方式三
在步骤110,代理实体通过方式一向网络存储功能实体完成去注册。
采用该实施方式,在代理实体如为SCP退网时,可以等效看作为一个服务service为空的NF,和其他NF一样,需要在NRF去注册本身的配置信息,具体可通过现有NF管理的NF去注册服务,将NF实例ID、去注册的原因指示信息上报至NRF,完成去注册。具体实现流程图4所示,包括:
S1131,Proxy向NRF发送NF管理的NF去注册请求,也即步骤S110中的管理请求,该NF去注册请求中包括NF实例ID,用于对应记录代理实体的实例ID;以及还包括去注册的原因指示信息;
S1132,NRF标记该代理实体的不可用状态,对该代理实体进行去注册;
S1133,NRF向Proxy发送NF管理的NF去注册响应。
利用上述的过程,Proxy通过调用网络功能NF管理服务,能够完成Proxy在NRF上的去注册。
实施方式四
在步骤S110,代理实体通过方式二向网络存储功能实体发送注册请求。
采用该方式,通过为Proxy定义一套新的NRF服务,也即代理管理服务,用于Proxy的注册、更新或去注册。
具体地,在用于Proxy的注册时,通过为NRF定义代理管理的代理注册服务,在代理实体入网时,通过调用该服务,完成配置信息的注册。其中,如图5所示,代理实体发送注册请求的过程包括:
S1141,Proxy向NRF发送Proxy管理的Proxy注册请求,也即步骤S110中的管理请求;
其中,可选地,该Proxy注册请求中包括代理类型、实例标识ID、公共陆地移动网PLMN标识ID、地址信息、配置能力、所提供代理的功能信息、所在网络的网络状况信息和周边可服务网络实体的实体信息。
在Proxy注册请求中,具体包括:
代理类型字段,用于记录所述代理实体的所述代理类型;
代理实例标识ID字段,用于记录所述代理实体的所述实例标识ID;
所提供代理的功能信息的名称字段,用于记录所述代理实体所提供的功能信息;
PLMN标识ID字段,用于记录所述代理实体的PLMN标识ID;
代理配置字段,用于分别记录所述代理实体的配置能力、所在网络的网络状况信息和周边可服务网络实体的实体信息。
其中,通过代理类型字段,代理实体提供本身的代理类型,如为“SCP”类型;通过代理实例标识ID字段,代理实体提供本身的代理实例标识ID;通过所提供代理的功能信息的名称字段,代理实体提供所提供代理的功能信息,如为间接通信或委托发现等;通过PLMN标识ID字段,提供所述代理实体的PLMN标识ID,以注册本身的代理配置。
在此基础上,上述配置信息中的内容包括目标规范中NF配置中的内容,并新增了代理配置字段,可选地,该代理配置字段可以为多个,用于分别记录所述代理实体的配置能力、所在网络的网络状况信息和周边可服务网络实体的实体信息。
其中,该配置能力包括并不限于仅能够包括优先权priority、容量capacity、负荷、地区locality和服务范围ServingScope等;所在网络的网络状况信息包括带宽、速率、时延、缓存buffer和消息排队情况;周边可服务网络实体的实体信息可以包括NF和/或Proxy。
可选地,该实施方式中,与实施方式一相同,在Proxy入网注册时,也即在代理实体发送的注册请求中,周边可服务网络实体的实体信息记录为空,或者记录为预设配置值,该预设配置值可以表示proxy计划服务的NF和/或Proxy。
进一步,可选地,该周边可服务网络实体的实体信息可在代理实体获得周边网络实体信息后进行动态更新。具体地,代理实体可以通过查询NRF或订阅状态通知,获得最新的周边可服务的NF和/或Proxy,并添加至“该周边可服务网络实体的实体信息”的参数中,并进一步将该参数值通过配置更新请求,更新至NRF上,以能够在NRF上维护该参数的最新值,以供其他NF 或Proxy使用。
在实施方式四中,如图5所示,在步骤S1141,Proxy向NRF发送Proxy管理的Proxy注册请求之后,所述方法还包括:
S1142,NRF存储Proxy配置,也即存储注册请求中代理实体的配置信息;
S1143,NRF向Proxy发送Proxy管理的Proxy注册响应。
利用上述的过程,Proxy通过调用代理管理的代理注册服务,能够完成Proxy在NRF上的注册。
实施方式五
在步骤S110,代理实体通过方式二向网络存储功能实体配置更新请求。
采用该方式,通过为NRF定义代理管理的代理更新服务,在代理实体入网后有配置信息更新时,通过调用该服务,完成自身的配置信息更新。具体地,代理实体需要提供自身的代理实例ID,并上报所要更新的代理配置。
具体实现流程如图6所示,包括:
S1151,Proxy向NRF发送代理管理的代理更新请求,也即步骤S110中的管理请求,该代理更新请求中包括代理实例ID,用于对应记录代理实体的实例ID;以及还包括所需要更新的配置信息;
S1152,NRF对代理更新请求中代理实体的相应配置信息进行更新;
S1153,NRF向Proxy发送代理管理的代理更新响应。
可选地,在步骤S1151中,Proxy所需要更新的配置信息可以包括周边可服务网络实体的实体信息,通过将该实体信息更新至NRF,以能够在NRF上始终维护该参数的最新值,供其他NF或Proxy使用。
利用上述的过程,Proxy通过调用网络功能Proxy管理服务,能够完成Proxy在NRF上的配置更新。
实施方式六
在步骤S110,代理实体通过方式二向网络存储功能实体完成去注册。
采用该实施方式,通过为NRF定义代理管理的代理去注册服务,在代理实体退网时,通过调用该服务,完成去注册。其中,代理实体需要提供自身的代理实例ID和去注册的原因指示信息等。具体实现流程如图7所示,包括:
S1161,Proxy向NRF发送Proxy管理的Proxy去注册请求,也即步骤S110 中的管理请求,该NF去注册请求中包括Proxy实例ID,用于记录代理实体的实例ID;以及还包括去注册的原因指示信息;
S1162,NRF标记该代理实体的不可用状态,对该代理实体进行去注册;
S1163,NRF向Proxy发送Proxy管理的Proxy去注册响应。
利用上述的过程,Proxy通过调用Proxy管理服务,能够完成Proxy在NRF上的去注册。
需要说明的是,采用上述方式一和方式二分别实现的代理实体的注册,代理实体可以将配置信息注册到当前网络服务范围内的所有NRF中,也即可以同时注册到多个NRF中的多个层级的NRF中。
进一步,可选地,本公开实施例所述通信方法,还能够进一步实现代理实体的路由查询、状态通知服务查询以及确定下一跳的路由信息。
可选地,代理实体可以通过NRF查询和订阅NRF的状态通知服务查询中的至少之一的方式,获得代理实体的路由信息。
因此,其中一实施方式,所述方法还包括:
通过网络功能NF发现服务,向所述网络存储功能实体发送路由查询请求;
其中,所述路由查询请求中请求获取目标路由类型的字段记录为网络功能NF或者代理。
进一步,可选地,所述方法还包括:
获取所述网络存储功能实体根据所述查询请求返回的响应信息;
其中,所述响应信息中包括目标网络实体;所述目标网络实体包括目标网络功能NF和/或目标代理。
具体地,举例说明,当第一代理实体需要查询自己的下一跳地址时(下一跳可以为一个NF,也可以为一个代理实体),第一代理实体通过已有的NF发现服务,向NRF发送发现查询请求,即能够查询到下一跳的地址(如为第二代理实体,其中该第二代理实体可以通过上述实施方式一或实施方式四的方式,已在NRF上进行了注册,则可以被第一代理实体查询到;如下一步为一个NF时,则情况相同,由于已在NRF上进行了注册,也能够被第一代理实体查询到)。
本公开实施例中,采用该实施方式,在NF发现服务请求中必须输入的所需要查询的目标NF的NF类型,扩展为目标NF或目标代理的类型,即在请求中可以请求目标NF为一个NF或者为一个Proxy。在此情况下,NRF如果具备相应信息的话,则应同时提供目标NF和目标Proxy,其中,目标Proxy也可以有多个,以能够供第一代理实体选择。
实施方式七
根据以上,本公开实施例还提供实施方式七,通过该实施方式,Proxy能够向NRF发送路由查询请求,获取下一跳的路由信息。具体地,如图8所示,该实施方式的具体过程,包括:
S210,Proxy向NRF发送NF发现查询请求;可选地,该NF发现查询请求中包括Proxy的实例标识ID;
S220,NRF验证NF服务或者代理发现;
S230,NRF向Proxy返回NF发现查询的响应信息;该响应信息中包括所查询到的目标网络实体,该目标网络实体包括目标网络功能NF和/或目标代理。
采用该实施方式,通过上述过程的NF发现查询服务,Proxy能够查询到下一跳的地址信息。
实施方式八
本公开实施例的另一实施方式,Proxy还可以通过订阅NRF的状态通知服务查询下一跳的地址信息。
具体地,代理实体(如为第一代理实体)在入网时,可以注册并同时订阅NRF的NF状态订阅服务;当在同一NRF内,有其他代理实体(如为第二代理实体)入网注册、更新或去注册时,NRF即根据所订阅的NF状态订阅服务,将第二代理实体的配置信息通过NF状态通知服务通知第一代理实体,因此第一代理实体无需发送查询请求,即能够获知第二代理实体的配置信息。同样情况,当在该NRF上有注册、更新或去注册的NF时,NRF也可以将有配置更新的该NF的配置信息发送至第一代理实体。
因此,根据以上方式,第一代理实体可以获得第二代理实体(数量可以为一个或多个)和目标NF的配置信息,以能够利用该配置信息,确定下一 跳的地址信息。
具体地,如图9所示,Proxy通过订阅NRF的状态通知服务查询下一跳的地址信息的具体过程,包括:
S310,Proxy向NRF发送NF管理的NF状态订阅请求;
S320,NRF验证NF服务或者Proxy状态订阅请求;
S330,NRF向Proxy发送NF状态订阅请求的响应信息;
S340,NRF确认NF和/或Proxy的最新的注册、更新和去注册,确定目标网络功能NF和/或目标代理;
S350,向Proxy发送NF管理的NF状态通知消息,该NF状态通知消息中包括目标网络功能NF和/或目标代理更新后的配置信息。
采用上述实施方式,通过订阅NRF的状态通知服务,Proxy能够查询到下一跳的地址信息。
采用上述的实施方式七和实施方式八,Proxy只能够获得其可查询到的NRF,或订阅过状态通知服务的本地NRF的服务范围内的其他NF和Proxy信息。如果Proxy的目标NF或Proxy不在本地NRF服务范围内,例如跨PLMN的场景,则需要通过本地NRF(如为NRF1),通过NRF间的N27接口去其服务范围外的其他的NRF(如为NRF2)上查询。
因此,本公开实施例还提供实施方式九,用于实现跨NRF的路由信息查询,具体流程如图10所示,包括:
S410,Proxy向NRF1发送NF发现查询请求;可选地,该NF发现查询请求包括Proxy的实例标识ID,以及所查询的目标NF或Proxy的信息;
S420,NRF1确认NF发生查询请求所查询的目标NF或Proxy的信息没有在本地NRF1上注册;
S430,NRF1向NRF2发送NF发现查询请求;
S440,NRF2验证NF服务或者代理发现;
S450,NRF2向NRF1返回NF发现查询的响应信息;该响应信息中包括所查询到的目标网络实体,该目标网络实体包括目标网络功能NF和/或目标代理;
S460,NRF1将所接收到的包括目标网络实体的响应信息发送至Proxy, 使Proxy能够获知NRF2的服务范围内的NF和/或Proxy。
通过上述实施方式,Proxy在向NRF1发送NF发现查询请求后,获得NRF2服务范围内的NF和/或Proxy。
本公开实施例另一方面,可选地,在根据上述实施方式七或实施方式九,通过向NRF发送NF发现查询请求,获得目标网络功能NF和/或目标代理的配置信息后,以及在根据上述实施方式八,通过订阅NRF的状态通知服务查询,获得目标网络功能NF和/或目标代理的配置信息后,可以进一步包括:
根据所述目标网络功能NF和/或目标代理,更新所述周边可服务网络实体的实体信息;
向网络存储功能实体发送配置更新请求,更新周边可服务网络实体的实体信息。
这样,通过将该实体信息更新至NRF,以能够在NRF上始终维护该参数的最新值,供其他NF或Proxy使用。
本公开实施例所述通信方法,Proxy在NRF上进行了注册之后,通过上述向NRF发送NF发现查询请求和订阅NRF的状态通知服务查询,能够被其他NF和Proxy发现,并获得NRF所查询到的目标网络功能NF和/或目标代理的配置信息,以进一步能够由Proxy确定下一跳路由信息。
具体地,所述方法还包括:
根据所述响应信息中的所述目标网络功能NF和/或所述目标代理的配置信息、所述NF状态通知消息中的所述目标网络功能NF和/或所述目标代理的配置信息、自身的配置信息和网络策略中的至少之一,确定下一跳的路由信息。
其中,通过上述向NRF发送NF发现查询请求和订阅NRF的状态通知服务查询的方式,第一代理实体获取了目标NF的NF配置和第二代理实体(可以为一个或多个)的代理配置,因此能够了解目标NF和第二代理实体的地址及相关参数。
举例说明,若第一代理实体通过比较认为通过第二代理实体转发信息更为合适,则会选择第二代理实体转发,若认为直接发送更合适,则会直接将信息发送至目标NF。
具体地,第一代理实体可以通过分析当前NF配置中已有的配置能力参数(如包括优先权priority、容量capacity、负荷、地区locality和服务范围ServingScope等)、最新获得的NF配置和/或代理配置参数(如包括网络状态信息和周边可服务网络实体的实体信息等)、自身配置和网络策略的至少之一,依据相关算法,计算选择自己的下一跳路由。
因此,本公开实施例还提供实施方式十,如图11所示,包括:
S510,第一代理实体通过上述向NRF发送NF发现查询请求和订阅NRF的状态通知服务查询的方式,获得新增的目标NF和相关的第二代理实体的配置信息;
S520,第一代理实体通过当前NF配置中已有的配置能力参数,新增获取的NF和第二代理实体的配置信息、自身的配置信息和网络策略进行综合比较,确定下一跳路由,其中下一跳路由可以为目标NF或者其中一第二代理实体。
根据以上,采用本公开实施例所述通信方法,通过Proxy向NRF发送注册请求、配置更新请求和去注册请求,NRF能够获得Proxy的配置信息,进一步地,Proxy通过向NRF发送NF发现查询请求、订阅NRF的状态通知服务查询以及进行NRF查询,Proxy能够查询到下一跳的路由信息;此外,在获得下一步的跳由信息的基础上,Proxy根据当前NF配置中已有的配置能力参数,新增获取的NF和第二代理实体的配置信息、自身的配置信息和网络策略进行综合比较,能够确定下一跳路由。
因此,本公开实施例所述通信方法,通过上述的方式,解决了Proxy如何自主的在NRF上注册/更新/去注册自己信息的问题,不必再通过相关技术中的手动配置的方法,达到节省大量人力成本的效果,另外还可以实现Proxy的自动化部署,实现网络自动化。
