Description

服务绑定的方法及装置
本申请要求于2019年10月11日提交国家知识产权局、申请号为201910963216.0、发明名称为“服务绑定的方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及服务绑定的方法及装置。
背景技术
第三代合作伙伴计划(3rd generation partnership project，3GPP)Release 15中，第五代移动通信技术(5 th generation，5G)核心网系统架构是基于服务化的架构(service based architecture，SBA)，SBA的主要目的是将每个网络功能(network function，NF)拆分成一个或者多个网络功能服务(NF service)，每个网络功能服务可以通过标准接口和其他网络功能服务互通，其中，具备服务消费者(service consumer)功能的NF称为NF服务消费者，具备服务生产者(service producer)功能的NF称为NF服务生产者，NF服务生产者和NF服务消费者可以包括一个或多个服务实例。
3GPP Release 16中进一步对Release 15的服务化架构进行了改进和优化，提出了间接通信模式，即将服务化架构中的部分公共功能，例如，间接通信(indirect communication)和委托发现(delegated discovery)，抽取出来，由服务通信代理(service communication proxy，SCP)网元统一提供。在间接通信模式中，NF服务消费者不直接与NF服务生产者通信，而是通过SCP和NF服务生产者进行通信，SCP在NF服务消费者和NF服务生产者之间路由消息，并且可以代表NF服务消费者进行服务发现和选择。以NF服务消费者与NF服务生产者之间通过两个SCP进行通信为例，NF服务消费者向SCP1发送服务请求，该服务请求包括发现与选择参数，SCP1接收到该服务请求后，根据该发现与选择参数进行路由规则匹配，将该请求路由给SCP2，SCP2接收到该服务请求后，根据该发现与选择参数进行路由规则匹配，并选择该NF服务生产者为该NF服务消费者提供服务。
3GPP Release 16中还定义了绑定机制。绑定机制是指NF服务生产者可以将NF服务消费者的服务实例1对某一资源的服务请求，绑定在NF服务生产者的服务实例1上，后续，NF服务消费者的服务实例对该资源进行服务请求时，均由NF服务生产者的服务实例1进行处理，直到解除绑定关系。解除绑定关系后，其他NF服务生产者的服务实例也可以处理该资源的服务请求。
现有技术中，在间接通信模式下对NF服务生产者的服务实例1和NF服务消费者的服务实例1建立绑定关系后，SCP仍然要根据NF服务生产者的服务实例1的地址进行规则匹配和路由，并且保证服务实例1的服务请求均路由到服务实例1，过程较为复杂。

具体实施方式
下面将结合附图，对本申请实施例中的技术方案进行描述。
本申请实施例提供的服务绑定的方法可以应用于图1所示的服务化架构。其中，图1以5G的网络服务架构为例展示了NF和实体之间的交互关系以及对应的接口。其中，5G系统的3GPP基于SBA包含的网络功能和实体主要包括：终端设备(terminal equipment，TE)、接入网(access network，AN)或无线接入网(radio access network，RAN)、用户面功能(user plane function，UPF)、数据网络(data network，DN)、接入管理功能(access management function，AMF)、会话管理功能(session managent function，SMF)、认证服务功能(authentication server function，AUSF)、策略控制功能(policy control function，PCF)、应用功能(application function，AF)、网络切片选择功能(network slice selection function，NSSF)、统一数据管理(unified data management，UDM)、网络开放功能(network dxposure function，NEF)和网络存储功能(NF repository function，NRF)。
其中，TE、(R)AN、UPF和DN一般被称为用户面网络功能和实体(或者用户面网元)，其他的部分则一般被称为控制面网络功能和实体(或者控制面网元)。控制面网元由3GPP定义了在一个网络里的处理功能，控制面网元具有3GPP定义的功能行为和3GPP定义的接口，NF能够作为一个运行在专有硬件上的网络元素，或者运行在专有硬件上的软件实例，或者在一个合适平台上进行实例化的虚拟功能，比如在一个云基础设备被实施。
下面对各个网元的主要功能做具体介绍。
(R)AN：(R)AN可以是AN，也可以是RAN。具体的，(R)AN可以是各种形式的基站，例如：宏基站，微基站，分散单元-控制单元(distribute unit-control unit，DU-CU)等。另外，上述基站还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器，或者中继站、接入点、车载设备、可穿戴设备或者未来演进的公共陆地移动网络(public land mobile network，PLMN)网络中的网络设备等。(R)AN主要负责空口侧的无线资源管理、服务质量管理、数据压缩和加密等。
UPF：主要负责用户数据的转发和接收。UPF可以接收来自DN的下行数据，然后通过(R)AN将该下行数据传输给TE。UPF还可以通过(R)AN接收来自TE的收上行数据，然后将该上行数据转发到DN。
DN：例如：DN可以是运营商服务网络、互联网接入或第三方服务网络等。DN可以通过PDU会话与TE进行信息交互。其中，PDU会话可以分为多种类型，如互联网协议版本4(internet protocol version 4，IPv4)、IPv6等。
AMF：主要负责控制面消息的处理，例如：接入控制、移动性管理、附着与去附着以及网关选择等。
SMF：主要用于会话管理，会话建立，TE的IP地址分配和管理等。
AUSF：主要负责网络安全，用于产生密钥，实现对于TE的双向鉴权等。
PCF：主要用于管理策略规则，管理用户订阅信息等。
UDM：主要用于鉴权信用处理，用户标识处理，访问授权，注册/移动性管理，订阅管理和短消息管理等。
NEF：主要用于监控、计费等。
NRF：主要用于提供内部/外部寻址功能等。
AF：主要用于与3GPP核心网进行交互，以提供服务。
其中，图1中的NSSF等其他网元的功能，可以参考常规技术中的相关描述，这里不再赘述。
其中，图1所示的TE和(R)AN之间可以采用空口技术相互通信。如图1所示，N1为TE和AMF之间的参考点，N2为(R)AN和AMF之间的参考点，N3为(R)AN和UPF之间的参考点，N4为SMF和UPF之间的参考点，N6为UPF和DN之间的参考点。图1所示的Namf为AMF提供的基于服务的接口，Nsmf为SMF提供的基于服务的接口，Nausf为AUSF提供的基于服务的接口，Nnssf为NSSF提供的基于服务的接口，Nnef为NEF提供的基于服务的接口，Nnrf为NRF提供的基于服务的接口，Npcf为PCF提供的基于服务的接口，Nudm为UDM提供的基于服务的接口，Naf为AF提供的基于服务的接口。
其中，图1中具备服务生产者功能的NF可以称为NF服务生产者，具备服务消费者的NF可以称为NF服务消费者。在间接通信模式下，NF服务生产者和NF服务消费者之间可以通过一个或多个SCP(图1中未示出)通信。
需要说明的是，上述图1仅作为一种网络服务架构示例。本申请实施例提供的服务绑定的方法还可以应用于其他网络架构。例如，第五代之后发展的其他移动通信系统，本申请实施例对此不作限定。
可选的，本申请实施例图1中的各网元，可以是一个设备内的一个功能模块。可以理解的是，该功能模块既可以是硬件设备中的网络元件，也可以是在专用硬件上运行的软件功能，或者是平台(例如，云平台)上实例化的虚拟化功能。
例如，图1中的各网元或者与一个或多个网元连接的SCP(图1中未示出)均可以通过图2中的通信装置200来实现。图2所示为可适用于本申请实施例的通信装置的硬件结构示意图。该通信装置200可以包括至少一个处理器201，通信线路202，存储器203以及至少一个通信接口204。
处理器201可以是一个通用中央处理器(central processing unit，CPU)，微处理器，特定应用集成电路(application-specific integrated circuit，ASIC)，或一个或多个用于控制本申请方案程序执行的集成电路。
通信线路202可包括一通路，在上述组件之间传送信息，例如总线。
通信接口204，使用任何收发器一类的装置，用于与其他设备或通信网络通信，如以太网接口，无线接入网接口(radio access network，RAN)，无线局域网接口(wireless local area networks，WLAN)等。
存储器203可以是只读存储器(read-only memory，ROM)或可存储静态信息和指令的其他类型的静态存储设备，随机存取存储器(random access memory，RAM)或者 可存储信息和指令的其他类型的动态存储设备，也可以是电可擦可编程只读存储器(electrically erasable programmable read-only memory，EEPROM)、只读光盘(compact disc read-only memory，CD-ROM)或其他光盘存储、光碟存储(包括压缩光碟、激光碟、光碟、数字通用光碟、蓝光光碟等)、磁盘存储介质或者其他磁存储设备、或者能够用于携带或存储具有指令或数据结构形式的期望的程序代码并能够由计算机存取的任何其他介质，但不限于此。存储器可以是独立存在，通过通信线路202与处理器相连接。存储器也可以和处理器集成在一起。本申请实施例提供的存储器通常可以具有非易失性。其中，存储器203用于存储执行本申请方案所涉及的计算机执行指令，并由处理器201来控制执行。处理器201用于执行存储器203中存储的计算机执行指令，从而实现本申请实施例提供的方法。
可选的，本申请实施例中的计算机执行指令也可以称之为应用程序代码，本申请实施例对此不作具体限定。
在具体实现中，作为一种实施例，处理器201可以包括一个或多个CPU，例如图2中的CPU0和CPU1。
在具体实现中，作为一种实施例，通信装置200可以包括多个处理器，例如图2中的处理器201和处理器207。这些处理器中的每一个可以是一个单核(single-CPU)处理器，也可以是一个多核(multi-CPU)处理器。这里的处理器可以指一个或多个设备、电路、和/或用于处理数据(例如计算机程序指令)的处理核。
下面将结合图1和图2对本申请实施例提供的服务绑定的方法进行具体阐述。其中，下述实施例中的网元或SCP可以具备图2所示部件。

可以理解的，本申请实施例中，第一NF，和/或第一SCP，和/或第二SCP，和/或第二NF可以执行本申请实施例中的部分或全部步骤，这些步骤仅是示例，本申请实施例还可以执行其它步骤或者各种步骤的变形。此外，各个步骤可以按照本申请实施例呈现的不同的顺序来执行，并且有可能并非要执行本申请实施例中的全部步骤。
需要说明的是，本申请实施例提供的服务绑定的方法是以第一NF和第二NF之间通过两个SCP进行通信为例，第一NF和第二NF之间通过一个或两个以上的SCP进行通信的过程，可以参考第一NF和第二NF之间通过两个SCP进行通信的过程，不予赘述。
如图3所示，为本申请实施例提供的一种服务绑定的方法，该服务绑定的方法包括步骤301-步骤308。
步骤301：第一NF向第一SCP发送第一服务的请求。

需要说明的是，该第一参数还可以有其他的命名，例如，发现与选择参数(discovery and selection parameters)，不予限制。
步骤302：第一SCP接收来自第一NF的第一服务的请求，并根据第一服务的请求向第二SCP发送该第一服务的请求和第二字段。
可选的，第一SCP中存储有第一路由规则，该第一路由规则用于指示该第一SCP接收到的消息的发送规则。
可选的，第二字段包括在超文本传输协议(hypertext transfer protocol，HTTP)的请求头中。例如，该第二字段包括在X-Forwarded-For(XFF)头中。
其中，XFF是用于识别通过HTTP代理或负载均衡方式，连接到网络服务器的客户端最原始的IP地址的HTTP请求头字段。
可选的，该第二字段包括第一NF的第一服务实例的地址。例如，该第二字段包括第一NF的第一服务实例的IP地址。
需要说明的是，第一NF的第一服务实例的地址还可以是第一NF的第一服务实例的域名，或第一NF的第一服务实例的统一资源定位器(uniform resource locator，URL)地址等。
可选的，第一SCP根据第一服务的请求向第二SCP发送该第一服务的请求和第二字段，包括：第一SCP根据该第一参数以及第一SCP的第一路由规则确定第二SCP；第一SCP向该第二SCP发送该第一服务的请求和第二字段。
进一步可选的，第一SCP向该第二SCP发送该第一服务的请求和第二字段，包括：第一SCP将该第二字段加入第一XFF请求头中；第一SCP向第二SCP发送第一服务的请求和第一XFF请求头。
需要说明的是，在第一SCP将该第二字段加入该第一XFF请求头中之前，该第一XFF请求头为空。
步骤303：第二SCP接收来自第一SCP的第一服务的请求和第二字段，并根据该第一服务的请求向第二NF发送第一服务的请求和第五字段。
可选的，第二SCP接收来自第一SCP的第一服务的请求和第二字段，包括：第二SCP接收来自第一SCP的第一服务的请求和第一XFF请求头。
可选的，该第二NF是图1所示服务化架构中的任一网元。该第二NF具有服务消费者的功能，或者，该第一NF具有服务消费者和服务生产者的功能。
可选的，该第二NF可以包括一个或多个服务实例。
进一步可选的，第一服务的请求还包括第二SCP的地址。

该第五字段可以包括第一NF的第一服务实例的地址，以及前n-1个SCP的地址，n为从该第一NF到该第二NF经过的SCP的个数。
本申请实施例是以第一NF和第二NF之间通过两个SCP进行通信为例，因此，n＝2，第五字段包括第一NF的第一服务实例的地址以及第一SCP的地址。
其中，第一SCP的地址可以是第一SCP的IP地址、第一SCP的域名，或第一SCP的URL地址等。
可选的，第二SCP中存储有第二路由规则，该第二路由规则用于指示该第二SCP接收到的消息的发送规则。
其中，第二路由规则和第一路由规则可以相同也可以不同。
可选的，第二SCP根据该第一服务的请求向第二NF发送第一服务的请求和第五字段，包括：第二SCP根据该第一服务的请求向第二NF的第一服务实例发送第一服务的请求和第五字段，其中，第二NF的第一服务实例为第二NF中的任一服务实例。
进一步可选的，第二SCP根据该第一服务的请求向第二NF的第一服务实例发送第一服务的请求和第五字段，包括：第二SCP根据该第一参数以及第二SCP的第二路由规则确定第二NF的第一服务实例；第二SCP向第二NF的第一服务实例发送第一服务的请求和第五字段。

需要说明的是，现有技术中，第一SCP根据第一参数以及第一SCP的第一路由规则确定第二SCP，以及第二SCP根据第一参数以及第二SCP的路由规则确定第二NF均是一个较为复杂的过程，第一SCP需要进行多次条件选择确定第二SCP，第二SCP也需要进行多次条件选择确定第二NF，而本申请实施例提供的服务绑定的方法，第一SCP可以直接根据请求头中的字段确定第二SCP，第二SCP可以直接根据请求头中的字段确定第二NF，从而简化了间接通信模式下建立绑定关系的两个网络功能之间的通信过程，提高信息转发的性能。
步骤304：第二NF接收来自第二SCP的第一服务的请求和第五字段，若第二NF确定绑定第二NF的第一服务实例，第二NF根据该第五字段生成第一路由信息。

可选的，若第二NF确定不绑定第二NF的第一服务实例，第二NF经第二SCP以及第一SCP向第一NF发送服务响应，该服务响应用于指示第二NF的第一服务实例为该第一NF的第一服务实例提供该第一服务。
可选的，该服务响应包括第二NF的第一服务实例的地址和/或第二NF的第一服务实例的标识。
步骤305：第二NF向第二SCP发送第一服务的响应。
其中，第一服务的响应包括第一路由信息。
可选的，第一服务的响应还包括和第二绑定信息。
其中，第二绑定信息可以用于指示绑定第二NF的第一服务实例。也就是说，第一NF接收到第一服务的响应后(或第一NF接收到第一服务响时)，第一NF发送的第一资源的服务请求均由第二NF的第一服务实例进行处理。即在第一NF接收到第一服务的响应后(或第一NF接收到第一服务响时)，以及在第一NF接收到绑定解除信息之前，第一NF发送的第一资源的服务请求均会路由到第二NF的第一服务实例。
其中，该第一资源是第二NF为第一服务的请求创建的资源。

基于图3所示方法，第一NF可以向第一SCP发送第一服务的请求，第一SCP接收到该第一服务的请求后，可以根据该第一服务的请求和第一SCP中存储的第一路由规则确定第二SCP，并向第二SCP发送第一服务的请求和第二字段，第二SCP接收到 该第一服务的请求和第二字段后，可以根据第一服务的请求和第二路由规则确定第二NF，并向第二NF发送第一服务的请求和第五字段，第二NF接收到第一服务的请求和第五字段后，若确定绑定第二NF的第一服务实例，可以根据第五字段生成第一路由信息，并将该第一路由信息包括在第一服务的响应经第二SCP和第一SCP发送给第一NF，后续，若第一NF再次发送第一资源的服务请求时，第一NF和第二NF之间的SCP可以不用进行规则匹配和路由，而是根据第一路由信息将该服务请求经第一SCP和第二SCP发送给第二NF，可以提高消息转发性能。
进一步可选的，在图3所示方法的第一种实现场景中，第一NF可以向第二NF发送第二服务的请求和第一字段，第一NF和第二NF之间的SCP可以不用进行规则匹配和路由，而是根据第一路由信息将第二服务的请求经第一SCP和第二SCP发送给第二NF。

步骤310：第一NF向第一SCP发送第二服务的请求和第一字段。
其中，第二服务的请求用于请求第二NF的第一服务实例为第一NF的服务实例提供该第二服务。

可选的，第三字段包括从第一NF到第二NF所述经过的SCP中，在第二SCP之后的SCP的地址，以及第二NF的第一服务实例的地址。
本申请实施例中，从第一NF到第二NF经过第一SCP和第二SCP，因此，第三字段包括第二NF的第一服务实例的地址。
需要说明的是，第三字段也可以与第一字段相同，即第三字段也可以包括第一NF的第一服务实例的地址、第一SCP的地址、第二SCP的地址以及第二NF的第一服务实例的地址；或者，第三字段可以包括第一SCP的地址、第二SCP的地址以及第二NF的第一服务实例的地址；或者，第三字段可以包括第二SCP的地址以及第二NF的第一服务实例的地址。
