Description

服务小区信息的更新方法及装置
本申请要求于2019年02月01日提交国家知识产权局、申请号为201910105750.8、申请名称为“服务小区信息的更新方法及装置”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，尤其涉及服务小区信息的更新方法及装置。
背景技术
在第五代(5th generation，5G)通信***中，基站采用集中式节点(centralized unit，CU)-分布式节点(distributed unit，DU)的架构。进一步的，CU又可以划分为集中式节点的用户面(CU user plane，CU-UP)和集中式节点的控制面(CU control plane，CU-CP)。
由于某些原因(例如DU的部署)，CU-UP和CU-CP经常需要更新服务小区信息。但是，当前的服务小区信息的更新流程较为繁琐，导致服务小区信息的更新时间较长，影响接入网的正常使用。
发明内容
本申请提供一种服务小区信息的更新方法及装置，以期减少服务小区信息的更新时间。
为达到上述目的，本申请提供如下技术方案：
第一方面，提供一种服务小区信息的更新方法，包括：CU-CP接收DU发送的N个服务小区信息，N为正整数；CU-CP向CU-UP发送N个服务小区信息；CU-CP接收CU-UP发送的指示信息，指示信息用于指示N个服务小区信息中的一个或多个服务小区信息是否更新成功。基于上述技术方案，N个服务小区信息是CU-UP直接发送给CU-UP的，并且这N个服务小区信息由CU-UP确定是否需要更新。可见，本申请的技术方案无需多个OAM***进行协商，从而减少了服务小区信息的更新时间，简化了服务小区信息的更新流程。另外，服务小区信息的更新流程通常是DU的部署流程的一部分。因此，简化服务小区信息的更新流程，可以简化DU的部署流程和部署周期。也即，本申请的技术方案有利于支撑接入网的自动部署，节省部署成本。
一种可能的设计中，服务小区信息包括以下参数中的至少一项：服务小区标识，服务小区所属的跟踪区(tracking area，TA)标识，服务小区支持的公共陆地移动网络(Public Land Mobile Network，PLMN)标识。

一种可能的设计中，服务小区信息包括以下参数中的至少一项：服务小区标识，服务小区所属的跟踪区信息，服务小区支持的PLMN标识。
一种可能的设计中，该方法还包括：DU向所述CU-CP发送所述DU的位置信息。

具体实施方式
当前，室内覆盖的方案主要包括以下两种：
方案一、基站分离为基带处理单元(Base band Unit，BBU)与射频拉远单元(Radio Remote Unit，RRU)，BBU与RRU通过光纤连接。从而，可以将RRU可部署至室内，以实现室内覆盖。但是，RRU同BBU之间的连接接口为通用公共射频接口(Common Public Radio Interface，CPRI)。受限于CPRI的容量，方案一不适用于高容量场景。
方案二、在室内部署微型基站。微型基站的发射功率较低，可以直接连接网关。但是，微型基站的分布式部署会使得多个微型基站之间互相干扰，影响用户的正常通信。
为了解决上述问题，业界提出一种新的室内覆盖方案：在室内部署HDU。第一，HDU与CU之间是在分组数据汇聚协议(packet data convergence protocol，PDCP)层和无线链路控制协议(radio link Control，RLC)层之间进行分割，HDU与CU之间采用F1接口。相较于CPRI，F1接口位于协议栈的更高层，F1接口所需的容量更小，因此可以克服容量受限的问题。第二、HDU集中部署在CU下，一个CU下的多个HDU可以通过CU进行集中式协调，避免多个HDU之间的互相干扰，从而能够保证用户的正常通信。
以上是对HDU的简单介绍。另外，部署了HDU的接入网的架构的具体描述可参考下文，在此不予赘述。
为了便于理解本申请实施例，下面对本申请涉及的一些术语进行简单介绍。
1、跟踪区、注册区(registration area，RA)
跟踪区，一片连续覆盖的小区组成的地理区域，用于终端的位置管理。一个跟踪区可以包括一个或者多个小区，但是一个小区只能属于一个跟踪区。
注册区，网络侧为终端分配的一片连续的地理区域。注册区可以包括一个跟踪区或者多个跟踪区。终端在注册区中移动时，不会触发跟踪区更新流程。
2、PLMN ID
PLMN ID由移动设备国家代码(mobile country code，MCC)和移动设备网络代码(mobile network code，MNC)构成。PLMN ID用于标识网络运营商。
3、跟踪区标识(tracking area identity，TAI)
跟踪区标识由PLMN ID与跟踪区代码(tracking area code，TAC)构成。其中，TAC也可以称为跟踪区编码，用于标识一个跟踪区。
在本申请的描述中，除非另有说明，“/”表示“或”的意思，例如，A/B可以表示A或B。本文中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。此外，“至少一个”是指一个或多个，“多个”是指两个或两个以上。“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。
需要说明的是，本申请中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其他实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
此外，本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施 例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
本申请实施例提供的技术方案可以应用于各种通信***，例如，5G通信***，未来演进***或者多种通信融合***等等。本申请提供的技术方案可以应用于多种应用场景，例如，机器对机器(machine to machine，M2M)、宏微通信、增强型移动带宽(enhanced mobile broadband，eMBB)、超高可靠超低时延通信(ultra-reliable & low latency communication，uRLLC)以及海量物联网通信(massive machine type communication，mMTC)等场景。
图1为本申请实施例提供的一种通信***的架构示意图。如图1所示，通信***包括接入网和核心网。以5G通信***为例，接入网为下一代无线接入网络(next generation radio access Network，NG-RAN)，核心网为5G核心网(5G core network，5GC)。
核心网包括各种核心网设备，例如接入与移动管理功能网元(access and mobility management function，AMF)、用户面功能网元(user plane function，UPF)、会话管理功能网元(session management function，SMF)等。
AMF属于核心网实体，主要负责移动性管理处理部分，例如：接入控制、移动性管理、附着与去附着以及SMF选择等功能。AMF为终端中的会话提供服务的情况下，会为该会话提供控制面的存储资源，以存储会话标识、与会话标识关联的SMF标识等。
SMF主要用于会话管理、终端的互联网协议(internet protocol，IP)地址分配和管理、选择可管理用户平面功能、策略控制、或收费功能接口的终结点以及下行数据通知等。
UPF可用于分组路由和转发、或用户面数据的QoS处理等。用户数据可通过该网元接入到数据网络(data network，DN)。
上述AMF、SMF以及UPF仅是一个名称，对设备本身不构成限定。可以理解的是，在5G网络以及未来其它的网络中，AMF、SMF以及UPF也可以是其他的名称，本申请实施例对此不作具体限定。例如，UPF还可以被称为UPF网元或者UPF实体，在此进行统一说明，以下不再赘述。
可选的，核心网设备可以由一个设备实现，也可以由多个设备共同实现，还可以是一个设备内的一个功能模块，本申请实施例对此不作具体限定。可以理解的是，上述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模块，或者是平台(例如，云平台)上实例化的虚拟化功能模块。
接入网包括接入网设备。其中，接入网设备可以是无线通信的基站或基站控制器等。例如，所述基站可以包括各种类型的基站，例如：微基站(也称为小站)，宏基站，中继站，接入点等，本申请实施例对此不作具体限定。在本申请实施例中，所述基站可以是全球移动通信***(global system for mobile communication，GSM)，码分多址(code division multiple access，CDMA)中的基站(base transceiver station，BTS)，宽带码分多址(wideband code division multiple access，WCDMA)中的基站(node B)，长期演进(long term evolution，LTE)中的演进型基站(evolutional node B，eNB或e-NodeB)，物联网(internet of things，IoT)或者窄带物联网(narrow band-internet of things，NB-IoT)中的eNB，未来5G移动通信网络或者未来演进的公共陆地移动网络(public land mobile network，PLMN)中的gNB，本申请实施例对此不作任何限制。
以接入网设备为gNB为例，在通信***中，两个gNB之间存在接口，本文称之为Xn接口。gNB与5GC之间存在接口，本文称之为Ng接口。
gNB可以采用CU-DU架构。也即，gNB由CU和至少一个DU构成。这种情况下，gNB的部分功能部署在CU上，gNB的另一部分功能部署在DU上。多个DU可以共用同一个CU，以节省成本。
CU与DU之间存在接口，本文称之为F1接口。CU与5GC之间存在接口，本文称之为Ng接口。两个CU之间存在接口，本文称之为Xn接口。可以理解的是，上述接口均为逻辑接口。在5G网络以及未来其他的网络中，上述接口还可以具有其他名称，本申请实施例对此不作限定。
CU和DU是按照协议栈进行功能切分。作为一种实现方式，CU部署有协议栈中的无线资源控制(radio Resource Control，RRC)层，PDCP层，以及业务数据适应协议(service data adaptation protocol，SDAP)层；DU部署有协议栈中的RLC层，媒体介入控制(media access control，MAC)层，以及物理层(physical layer，PHY)。从而，CU具有RRC、PDCP和SDAP的处理能力。DU具有RLC、MAC和PHY的处理能力。可以理解的是，上述功能的切分仅为一个示例，不构成对CU和DU的限定。也就是说，CU和DU之间还可以有其他功能切分的方式，本申请实施例在此不予赘述。
如图2所示，CU还可以分为CU-CP以及CU-UP。其中，CU-CP和CU-UP可以部署在同一物理设备上，也可以部署在不同物理设备上，本申请实施例对此不作限定。
CU-CP和CU-UP之间存在接口，本文称之为E1接口。CU-CP与5GC之间存在接口，本文称之为Ng接口(图2中未示出)。CU-CP与DU之间存在接口，本文称之为F1-C接口。CU-UP与DU之间存在接口，本文称之为F1-U接口。可以理解的是，上述接口均为逻辑接口。在5G网络以及未来其他的网络中，上述接口还可以具有其他名称，本申请实施例对此不作限定。
可选的，一个DU可以连接一个或多个CU-UP。一个CU-UP可以连接一个或多个DU。一个DU只能连接一个CU-CP。一个CU-CP可以连接一个或多个DU。一个CU-UP只能连接一个CU-CP。一个CU-CP可以连接一个或多个CU-UP。
作为一种实现方式，在CU部署了RRC层、PDCP层以及SDAP层的情况下，CU-CP负责RRC层，以及PDCP层的控制面部分功能，例如用于处理信令无线承载(signaling radio bearer，SRB)的功能。CU-UP负责SDAP层，以及PDCP层的用户面部分功能，例如用于处理数据无线承载(data radio bearer，DRB)的功能。
如图3所示，为本申请实施例提供一种部署了HDU的接入网的架构的示意图。
其中，在CU划分为CU-UP和CU-CP的场景下，HDU与CU-UP之间通过F1-U接口连接，HDU与CU-CP之间通过F1-C接口连接。
HDU管理***可以集成在CU中，也可以和CU进行共站部署。HDU管理***用于对HDU实现管理，例如对HDU的安装进行管理，对HDU的相关参数进行配置。
HDU网关是HDU架构中可选的设备。HDU的网关用于实现HDU的聚合，以减少HDU与CU之间的F1接口的数目，降低成本。
需要说明的是，HDU与DU之间的主要区别在于，DU为运营商部署的；HDU可以不是运营商部署的，例如是个人、家庭或者公司部署的。HDU一般部署于室内，用于保证终 端能够在室内正常通信。
在本申请实施例中，CU-UP、CU-CP、DU、HDU或者核心网设备等均可以通过图4中的通信装置来实现。
如图4所示，该通信装置包括：至少一个处理器101，通信线路102，存储器103以及至少一个通信接口104。
处理器101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102用于在上述组件之间传送信息。
通信接口104，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，RAN，无线局域网(wireless local area networks，WLAN)等。
存储器103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102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103用于存储执行本申请方案的计算机执行指令，并由处理器101来控制执行。处理器101用于执行存储器103中存储的计算机执行指令，从而实现本申请下述实施例提供的方法。

下面结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。
实施例一
为了便于描述，下文中将负责管理CU-CP的OAM***简称为OAM-CU-CP***，将 负责管理CU-UP的OAM***简称为OAM-CU-UP***，将负责管理DU的OAM***简称为OAM-DU***。
以运营商增加一个服务小区信息为例，当前的服务小区信息更新流程为：OAM-DU***、OAM-CU-CP***、OAM-CU-UP***互相协商，若这三个OAM***在协商后确认可以增加这个服务小区，则分别告知DU、CU-CP和CU-UP以增加该服务小区信息。
由于OAM***之间的协商需要较长的时间，因此导致服务小区信息的更新时间较长。另外，OAM-DU***、OAM-CU-CP***、OAM-CU-UP***可能属于不同厂商的设备。由于不同的厂商具有自己的私有信令，因此这三个OAM***可能需要进行信令适配以及能力协调，从而进一步增加服务小区信息的更新时间。
为了解决上述技术问题，如图5所示，为本申请实施例提供的一种服务小区信息的更新方法，该方法包括以下步骤：
S501、DU向CU-CP发送N个服务小区信息。相应的，CU-CP接收DU发送的N个服务小区信息。
其中，所述N个服务小区信息是预先配置在DU中的，N为正整数。
可选的，所述服务小区信息包括以下参数中的至少一项：服务小区标识，服务小区所属的跟踪区信息，以及服务小区支持的PLMN标识。在本申请实施例中，跟踪区信息包括TAI或者TAC。
作为一种实现方式，所述DU向CU-CP发送F1接口建立请求。其中，所述F1接口建立请求用于请求建立F1接口。所述F1接口建立请求包括所述N个服务小区信息。
S502、CU-CP向CU-UP发送该N个服务小区信息。相应的，CU-UP接收CU-CP发送的N个服务小区信息。
作为一种实现方式，CU-CP向CU-UP发送配置更新信息，所述配置更新信息携带所述N个服务小区信息。可以理解的是，在不同应用场景下，配置更新信息可以有不同的名称，例如DU增加请求消息。可以理解的是，CU-UP在接收到该DU增加请求消息之后，CU-UP可以获知网络中新增加了DU，并获取到该DU的服务小区信息。
S503、CU-UP确定是否更新所述N个服务小区信息。
其中，CU-UP对服务小区信息的更新操作包括：增加操作和、或删除操作。可以理解的是，增加操作是指CU-UP将服务小区信息增加到服务小区记录信息中。删除操作是指CU-UP将服务小区信息从服务小区记录信息中删除。
需要说明的是，服务小区记录信息用于记录CU-UP能够提供服务的一个或多个服务小区信息。换而言之，若一个服务小区信息不存在于服务小区记录信息中，则CU-UP不向该服务小区信息所对应的小区提供服务。可选的，服务小区记录信息可以以列表的形式实现，或者其他形式实现，本申请实施例不限于此。当服务小区记录信息以列表的形式实现时，服务小区记录信息可以被称为服务小区列表。
可选的，N个服务小区信息包括一个或多个第一服务小区信息，以及一个或多个第二服务小区信息。
其中，第一服务小区信息对应的更新操作为增加操作，也即第一服务小区信息为待增加的服务小区信息。在本申请实施例中，更新第一服务小区信息具体是指，将第一服务小区信息添加到服务小区记录信息中。相应的，不更新第一服务小区信息具体是指，不将第 一服务小区信息添加到服务小区记录信息中。
第二服务小区信息对应的更新操作为删除操作，也即第二服务小区信息为待删除的服务小区信息。在本申请实施例中，更新第二服务小区信息具体是指，删除服务小区记录信息所记录的第二服务小区信息。相应的，不更新第二服务小区信息具体是指，不删除服务小区记录信息所记录的第二服务小区信息。
可选的，CU-UP可按照以下情形中的任意一种，确定一个服务小区信息是第一服务小区信息还是第二服务小区信息。
情形一、服务小区信息还包括操作信息，所述操作信息用于指示服务小区信息对应的更新操作，也即该操作信息用于指示服务小区信息为第一服务小区信息还是第二服务小区信息。这样一来，CU-UP根据服务小区信息所包含的操作信息，确定服务小区信息是第一服务小区信息还是第二服务小区信息。
可选的，操作信息可以以至少一个比特来表示。例如，以一个比特为例，“0”表示服务小区信息是第一服务小区信息，“1”表示服务小区信息是第二服务小区信息。
情形二、服务小区信息在信令中的位置，用于指示该服务小区信息是第一服务小区信息，还是第二服务小区信息。这样一来，CU-UP根据服务小区信息在信令中的位置，确定该服务小区信息是第一服务小区信息还是第二服务小区信息。例如，若服务小区信息位于信令中的第一位置，则该服务小区信息是第一服务小区信息。若服务小区信息位于信令中的第二位置，则该服务小区信息是第二服务小区信息。
情形二中的信令可以是上文中的配置更新信息，本申请实施例不限于此。服务小区信息在信令中的位置具体是指信令中用于承载该服务小区信息的字段(或者比特域)。
下面具体介绍CU-UP如何确定是否更新第一服务小区信息。
方式一、对于CU-CP发送的任意一个第一服务小区信息，CU-UP默认更新该第一服务小区信息。
方式二、CU-UP可根据第一服务小区信息所包含的跟踪区信息，确定该第一服务小区信息所对应的小区是否位于CU-UP的服务区域内。若小区未位于CU-UP的服务区域内，则CU-UP确定不更新所述第一服务小区信息，也即不将第一服务小区信息增加到服务小区记录信息中。若小区位于CU-UP的服务区域内，则CU-UP确定更新所述第一服务小区信息，也即将第一服务小区信息增加到服务小区记录信息中。
方式三、CU-UP根据自身的能力信息，确定是否更新第一服务小区信息。示例性的，CU-UP的能力信息可以用于指示CU-UP所提供服务的小区的数目。例如，若当前CU-UP所提供服务的小区的数目达到所述能力信息所指示的上限值，则CU-UP不更新第一服务小区信息。若当前CU-UP所提供服务的小区的数目未达到所述能力信息所指示的上限值，则CU-UP更新第一服务小区信息。
可以理解的是，CU-UP可以使用上述方式一至方式三中至少一种方式，确定是否更新第一服务小区信息。
另外，方式一至方式三仅是本申请实施例所提供的示例，本申请实施例对于CU-UP如何确定是否更新第一服务小区信息的实现方式不作具体限定。
下面具体介绍CU-UP如何确定是否更新第二服务小区信息。
方式四、对于CU-CP发送的任意一个第二服务小区信息，CU-UP默认更新第二服务 小区信息。
方式五、CU-UP根据第二服务小区信息所对应的小区是否存在业务，确定是否更新该第二服务小区信息。也即，若第二服务小区信息所对应的小区存在业务，CU-UP不将该第二服务小区信息从服务小区记录信息中删除。若第二服务小区信息所对应的小区不存在业务，CU-UP将该第二服务小区信息从服务小区记录信息中删除。
可以理解的是，上述方式四和方式五仅是本申请实施例所提供的示例，本申请实施例对于CU-UP如何确定是否更新第二服务小区信息的实现方式不作具体限定。
S504、CU-UP向CU-CP发送指示信息。相应的，CU-CP接收CU-UP发送的指示信息。
其中，所述指示信息用于指示所述N个服务小区信息中的一个或多个服务小区信息是否更新成功。
可选的，所述指示信息可以采用以下实现方式中的一种或者多种：
实现方式一、所述指示信息包括N个更新结果消息，所述N个更新结果消息与所述N个服务小区信息一一对应，所述更新结果消息用于指示对应的服务小区信息是否更新成功。
示例性的，所述更新结果消息可以以一个或多个比特来表示。例如，以一个比特为例，“0”表示服务小区信息更新失败；“1”表示服务小区信息更新成功。
可选的，所述N个更新结果消息可以以位图的形式来实现，以减少信令开销。
可选的，当更新结果消息指示对应的服务小区信息未更新成功时，更新结果消息还可以包括：更新失败原因信息，更新失败原因信息用于说明服务小区信息更新失败的原因。可选的，更新失败原因信息包括原因索引，每一个原因索引对应一个更新失败的原因。
示例性的，第一服务消息信息更新失败的原因可以为：(1)当前CU-UP所提供服务的小区的数目达到所述能力信息所指示的上限值；(2)第一服务小区信息所对应的小区不位于CU-UP的服务区域内。
示例性的，第二服务小区信息更新失败的原因可以为：第二服务小区信息所对应的小区存在业务。
实现方式二、所述指示信息包括第一消息、第二消息、第三消息和第四消息中的至少一项。其中，第一消息用于指示更新成功的第一服务小区信息。第二消息用于指示更新成功的第二服务小区信息。第三消息用于指示更新失败的第一服务小区信息。第四消息用于指示更新失败的第二服务小区信息。
可选的，第三消息还可以包括每一个更新失败的第一服务小区信息对应的更新失败原因信息，更新失败原因信息用于说明该第一服务小区信息更新失败的原因。
可选的，第四消息还可以包括每一个更新失败的第二服务小区信息对应的更新失败原因信息，更新失败原因信息用于说明该第二服务小区信息更新失败的原因。
上述实现方式一和实现方式二仅为本申请实施例所提供的示例，本申请实施例对所述指示信息不作具体限定。
基于图5所示的技术方案，N个服务小区信息是CU-CP发送给CU-UP的，并且这N个服务小区信息由CU-UP确定是否需要更新。可见，本申请的技术方案无需多个OAM***进行协商，从而减少了服务小区信息的更新时间，简化了服务小区信息的更新流程。另外，服务小区信息的更新流程通常是DU的部署流程的一部分。因此，简化服务小区信息的更新流程，可以简化DU的部署流程和部署周期。也即，本申请的技术方案有利于支撑 接入网的自动部署，节省部署成本。
可选的，如图5所示，在步骤S503之后，该方法还包括步骤S505。
S505、CU-UP向OAM***发送通知消息。
其中，所示通知消息用于指示更新成功的M个服务小区信息，所述M个服务小区信息为所述N个服务小区信息的非零子集，M为正整数。
所述OAM***可以是上文中所提到的OAM-CU-UP***，也即用于管理CU-UP的OAM***。
这样一来，OAM***可以及时获知CU-UP所服务的小区的变更，以便于更好地管理CU-UP。
可选的，如图5所示，在步骤S504之后，该方法还包括步骤S506。
S506、CU-CP向DU发送指示信息。
作为一种实现方式，CU-UP向DU发送F1接口建立响应信息，该F1接口建立响应信息包括所述指示信息。
这样一来，DU可以获知它的服务小区信息是否更新成功。
可选的，如图6所示，步骤S501-S503可以替换为步骤S601-S603。
S601、DU向CU-CP发送DU的位置信息以及N个服务小区信息。
其中，所述DU的位置信息是预先配置在所述DU中的。
可选的，所述DU的位置信息以下信息中的至少一项：地理坐标、网络连接信息、覆盖范围信息以及其他覆盖信息。地理坐标可以为全球卫星导航***(the global navigation satellite system)的坐标，例如全球定位***(global positioning system，GPS)坐标。所述网络连接信息包括IP地址和/或MAC地址。所述覆盖范围信息包括所述DU支持的各个小区对应的天线下倾角和/或下行发射功率。所述其他覆盖信息包括：所述DU所在的宏小区(或者宏基站)的标识，和/或所述DU的邻小区(或者邻基站)的标识。
可选的，DU的位置信息以及N个服务小区信息可以各自独立发送，也可以封装在同一个信令中统一发送。
作为一种实现方式，所述DU向所述CU-CP发送F1接口建立请求，所述F1接口建立请求包括所述DU的位置信息以及N个服务小区信息。
S602、CU-CP向CU-UP发送DU的位置信息以及N个服务小区信息。
S603、CU-UP根据DU的位置信息，确定是否更新所述N个服务小区信息。
作为一种实现方式，CU-UP根据DU的位置信息，确定该DU是否位于CU-UP的服务区域内。若DU位于CU-UP的服务区域内，则CU-UP参考步骤S503的实现方式，确定是否更新所述N个服务小区信息。若DU不位于CU-UP的服务区域内，则CU-UP不更新所述N个服务小区信息。
基于图6所示的技术方案，DU的位置信息用于使得CU-UP能够确定DU所在的位置。从而，CU-UP基于DU所在的位置，能够确定该DU是否位于CU-UP的服务区域，从而CU-UP能够确定是否更新该DU的服务小区信息，也即CU-UP能够确定是否为该DU提供服务。这样一来，一方面，避免CU-UP连接了超出服务区域的DU；另一方面，避免DU部署在不能提供正常服务的CU-UP下。
可以理解的是，图5或图6所示的技术方案中DU所执行的步骤同样可以由HDU来 执行。也即，图5或图6所示的技术方案适用于HDU。基于上述技术方案，当网络新增HDU而需要更新服务小区信息时，由于无需OAM***之间的协商，因此减少了服务小区信息的更新时间，有利于HDU的快速部署，从而可以适应HDU随机部署的场景。
实施例二
HDU支持的网络包括三种接入类型，分别是CSG、混合用户组(hybrid subscriber group，HSG)、以及开放用户组(open subscriber group，OSG)。其中，CSG仅支持签约用户接入。HSG支持签约用户和非签约用户接入，但签约用户的优先级高于非签约用户。OSG支持所有用户接入。在本申请实施例中，接入类型为CSG或者HSG的网络均可以称为CSG网络，并且，每个CSG网络具有对应的CSG ID。
在部署了HDU的情况下，CU所服务的小区中，一部分小区可能是CSG小区。当前，CU仅向核心网上报TAI和CSG ID。这样一来，核心网仅仅知道CU所提供服务的小区中存在CSG小区，但是并不知道哪一个小区是CSG小区，也不知道哪一个TAI对应的小区是CSG小区。因此，核心网在为终端分配相应的注册区或者跟踪区时，核心网分配的注册区可能不适合该终端，影响终端的正常通信。例如，CSG小区#1的接入类型为CSG，终端不是CSG小区#1的签约用户，因此终端不能接入CSG小区#1。若核心网为终端分配的注册区包括CSG小区#1，那么当终端移动到CSG小区#1时，终端并不会发起注册区的更新流程。但是，如果这个时候有下行数据到达，核心网并不能通过CSG小区#1将该下行数据发送给终端，从而导致数据包被丢弃，进而影响了终端的正常通信。
为了解决上述技术问题，如图7所示，为本申请实施例提供的一种配置上报的方法，该方法包括以下步骤：
S701、CU获取K个CSG信息。
其中，所述K个CSG信息来自于一个或多个DU，K为正整数。
作为一种实现方式，所述CU可以从一个或多个DU分别获取一个或多个CSG信息。
需要说明的是，所述K个CSG信息预先配置在CU中，CU可以不执行步骤S701。也即，步骤S701是可选的执行步骤。
在本申请实施例中，所述CSG信息用于指示CU支持的至少一个CSG ID。在本申请实施例中，所述CSG信息用于指示TA与CSG ID之间的对应关系。或者，所述CSG信息用于指示PLMN与CSG ID之间的对应关系。又或者，所述CSG信息用于指示小区与CSG ID之间的对应关系。
可选的，所述CSG信息包括跟踪区信息和至少一个CSG ID。可选的，所述跟踪区信息为TAI或者TAC。可以理解的是，所述CSG信息所包含的跟踪区信息用于指示该CSG信息对应的跟踪区。
或者，所述CSG信息包括PLMN标识和至少一个CSG ID。可以理解的是，所述CSG信息所包含的PLMN标识用于指示该CSG信息对应的PLMN。
又或者，所述CSG信息包括小区标识和至少一个CSG ID。可以理解的是，所述CSG信息所包含的小区标识用于指示该CSG信息对应的小区。
又或者，所述CSG信息包括跟踪区信息和至少一个CSG子信息。所述CSG子信息包括至少一个CSG ID。并且，所述CSG子信息还包括小区标识和PLMN标识中的至少一项。
又或者，所述CSG信息包括PLMN标识和至少一个CSG子信息。所述CSG子信息包括小区标识和至少一个CSG ID。
可选的，所述CSG信息还可以包括接入类型。其中，所述接入类型包括第一接入类型和第二接入类型。第一接入类型的网络仅允许签约用户接入。第二接入类型的网络允许签约用户和非签约用户接入，但是签约用户的优先级高于非签约用户。第一接入类型还可以称为CSG接入类型，或者直接简称为CSG。第二接入类型还可以称为HSG接入类型，或者直接简称为HSG。接入类型所适用的网络的范围可以是跟踪区，或者PLMN，又或者小区，本申请实施例不限于此。
可选的，在CU采用图2所示的架构时，也即CU划分为CU-CP和CU-UP的情况下，步骤S701具体实现为：CU-CP获取K个CSG信息。
S702、CU向核心网设备发送K个CSG信息。
可选的，在CU采用图2所示的架构时，也即CU划分为CU-CP和CU-UP的情况下，步骤S702具体实现为：CU-CP向核心网设备发送所述K个CSG信息。
作为一种实现方式，CU向核心网设备发送Ng接口建立请求信息(Ng setup request)，该Ng接口建立请求信息携带所述K个CSG信息。可选的，在接收到所述Ng接口建立请求信息之后，核心网设备向CU发送Ng接口建立响应信息(Ng setup response)。
作为另一种实现方式，CU向核心网设备无线接入网配置更新信息(RAN configuration update)，该无线接入网配置更新信息携带所述K个CSG信息。可选的，在接收到所述无线接入网配置更新信息之后，核心网设备向CU发送无线接入网配置更新响应信息(RAN configuration update ACK)。
在本申请实施例中，所述核心网设备可以是AMF，也可以是其他核心网设备，本申请实施例对此不作任何限定。
基于图7所示的技术方案，由于CSG信息包括跟踪区信息(或者小区标识)和至少一个CSG ID。因此，CU通过向核心网设备发送K个CSG信息，使得核心网设备能够获知TA(或者小区)与CSG ID的对应关系。这样一来，在终端进行注册流程或者其他流程中，核心网设备可以为终端分配合适的注册区。
实施例三
在部署了HDU的情况下，CU所服务的小区中，一部分小区可能是CSG小区。当前，在终端准备接入CSG小区时，通信网络需要对终端进行认证，以确定终端是否是该CSG小区的签约用户。当前，终端的认证流程由核心网负责，认证流程较为繁琐。并且，核心网仅认证终端是否为当前服务小区的CSG签约用户。这导致在终端的每一次的切换过程(或者移动过程，又或者辅助基站(secondary Node)添加的过程)，核心网都需要对终端进行一次认证，进一步增大了信令开销。
为了解决上述技术问题，如图8所示，为本申请实施例提供的一种CSG管理方法，该方法包括以下步骤：
S801、CU从核心网设备获取终端对应的CSG签约信息。
其中，终端对应的CSG签约信息用于指示终端签约的至少一个CSG ID。在本申请实施例中，CSG签约信息包括多个CSG ID信息，每一个CSG ID信息包括一个CSG ID。
作为一种实现方式，所述多个CSG ID信息中每一个CSG ID信息所指示的CSG ID均 为该终端签约的CSG ID。换而言之，核心网设备仅通知CU终端签约了哪些CSG ID。
作为另一种实现方式，所述多个CSG ID信息中每一个CSG ID信息还包括指示信息，所述指示信息用于指示该CSG ID信息所包含的CSG ID是否是终端签约的CSG ID。
可选的，CSG ID信息还可以包括PLMN标识、跟踪区信息和小区标识中的至少一项。需要说明的是，CSG ID信息所包括的PLMN标识用于指示CSG ID生效的PLMN。CSG ID信息所包括的跟踪区信息用于指示CSG ID生效的跟踪区。CSG ID信息所包括的小区标识用于指示CSG ID生效的小区。
可选的，CSG ID信息还包括接入类型。其中，所述接入类型包括第一接入类型和第二接入类型。其中，第一接入类型的网络仅允许签约用户接入。第二接入类型的网络允许签约用户和非签约用户接入，但是签约用户的优先级高于非签约用户。第一接入类型还可以称为CSG接入类型，或者直接简称为CSG。第二接入类型还可以称为HSG接入类型，或者直接简称为HSG。接入类型所适用的网络的范围可以是跟踪区，或者PLMN，又或者小区，本申请实施例不限于此。
可选的，在CU采用图2所示的架构时，也即CU划分为CU-CP和CU-UP的情况下，步骤S801具体实现为：CU-CP从核心网设备获取终端对应的CSG签约信息。
作为一种实现方式，所述CU接收核心网设备发送的初始上下文建立请求信息(initial context setup request)，所述初始上下文建立请求信息包括所述终端对应的CSG签约信息。之后，所述CU向核心网设备发送初始上下文建立响应信息(initial context setup response)，所述初始上下文建立响应信息是初始上下文建立请求信息的响应。
作为另一种实现方式，所述CU向所述核心网设备发送路径转移请求信息(path switch request)，所述路径转移请求信息包括终端的信息。之后，所述CU接收所述核心网设备发送的路径转移请求响应信息(path switch request ACK)，所述路径转移请求响应信息包括所述终端对应的CSG签约信息。
作为另一种实现方式，所述CU向所述核心网设备发送用户上下文修改请求信息(UE context modification request)，所述用户上下文修改请求信息包括终端的信息。之后，所述CU接收所述核心网设备发送的用户上下文修改响应信息(UE context modification response)。所述用户上下文修改响应信息包括所述终端对应的CSG签约信息。
可选的，上述终端的信息包括终端的标识。示例性的，所述终端的标识可以为IP地址、MAC地址、无线网络临时标识(radio network temporary identity，RNTI)中的至少一项，本申请实施例对此不作任何限制。
在本申请实施例中，所述核心网设备可以是AMF，也可以是其他核心网设备，本申请实施例对此不作任何限定。
S802、CU保存所述终端对应的CSG签约信息。
在CU采用图2所示的架构时，也即CU划分为CU-CP和CU-UP的情况下，步骤S802具体实现为：CU-CP保存所述终端对应的CSG签约信息。
基于图8所示的技术方案，由于核心网设备预先将终端对应的CSG签约信息发送给CU，因此在一些流程中，例如终端准备接入CSG小区的流程中，CU可以根据终端的CSG签约信息，对终端进行认证，而不需要通过核心网来对终端进行认证，从而减少接入网与核心网之间的信令交互，节省信令开销。
如图9所示，为本申请实施例提供的一种认证方法，该方法包括以下步骤：
S901、终端发送RRC连接请求，该RRC连接请求用于请求建立与第一CSG小区的RRC连接，以接入第一CSG小区。
其中，第一CSG小区可以是任意一个CSG小区，本申请实施例对此不作限制。
S902、CU根据终端的CSG签约信息，确定终端是否能够接入第一CSG小区。
可以理解的是，终端的CSG签约信息的获取方法可以参考图8所示的实施例，在此不再赘述。
作为一种实现方式，CU根据终端的CSG签约信息，确定终端是否是第一CSG小区的签约用户。若终端不是第一CSG小区的签约用户，且第一CSG小区的接入类型为CSG，则CU确定该终端不能够接入第一CSG小区。若终端是第一CSG小区的签约用户，或者第一CSG小区的接入类型为HSG，则CU确定该终端能够接入第一CSG小区。
若终端能够接入第一CSG小区，则CU执行下述步骤S903a。
若终端不能够接入第一CSG小区，则CU执行下述步骤S903b。
或者，若终端不能够接入第一CSG小区，则CU根据终端的CSG签约消息，确定是否存在终端签约的第二CSG小区。若不存在终端签约的第二CSG小区，则CU执行下述步骤S903b。若存在终端签约的第二CSG小区，则CU向第二CSG小区所属的DU发送UE上下文建立流程，以使得第二CSG小区所属的DU作为该终端的辅助节点；之后，CU执行下述步骤S903c，以配置该终端签约的第二CSG小区作为终端的辅助小区。
可选的，第二CSG小区与第一CSG小区可以位于同一DU下，也可以位于不同的DU下。
可选的，所述第二CSG小区与所述第一CSG小区位于同一TA中。
S903a、CU向终端发送RRC建立消息。
可以理解的是，CU向终端发送RRC建立消息，以允许终端建立RRC连接，从而接入第一CSG小区。
S903b、CU向终端发送RRC释放消息。
可以理解的是，CU向终端发送RRC释放消息，以拒绝终端建立RRC连接，从而避免终端连接到未签约的CSG小区中。
可选的，RRC释放消息也可以称为RRC拒绝消息，本申请实施例对此不作限定。
S903c、CU向终端发送RRC重配置消息。
可选的，RRC重配置消息包括第二CSG小区所属的DU的配置信息。RRC重配置消息用于重新配置终端的RRC连接，以使得终端能够接入第二CSG小区。
基于上述技术方案，在终端接入CSG小区的流程中，CU可以根据终端的CSG签约信息，对终端进行认证，而不需要通过核心网来对终端进行认证，从而减少接入网与核心网之间的信令交互，节省信令开销。
