一种小区管理的方法和设备

本申请要求在2019年06月19日提交中国专利局、申请号为201910533235.X、申请名称为“一种小区管理的方法和设备”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，特别涉及一种小区管理的方法和设备。
背景技术
当今无线通信技术飞速发展，随着无线网络部署的密集化，无线网络重叠覆盖的情况越来越常见，在密集部署网络中，为了在保证用户体验的同时，提高网络能效，网络需要根据小区的网络负载情况动态的开启或关闭重复覆盖区域的小小区。如图1所示，分别表示了宏基站与微基站的覆盖区域，其中宏基站完全覆盖了微基站的服务小区，因此，可将微基站的服务小区视为宏基站的小小区。假设小小区当前为非激活状态，当宏基站检测到宏基站服务小区当前的网络负载较高时，可以向微基站请求激活小小区，疏散宏基站的网络负载压力，如图2所示，eNB(5G基站)1为宏基站，eNB2为微基站，宏基站向微基站发送小区激活请求信息，微基站向宏基站发送小区激活应答的流程示意图，通过此流程，小小区的状态由非激活小区转为激活小区；当微基站检测到小小区的网络负载较低时，则可以向宏基站请求将小小区内的有效用户切换到宏基站上去，以关闭小小区，将小小区的状态由激活小区转为非激活小区，以降低能耗。
现有，小小区的开启或关闭完全根据当前宏基站和/或微基站的网络负载状态来决定的，因此，可能造成下列情况：
1)多个网络负载较高的基站都需要激活邻基站的小区时，并不能确定各 基站的邻基站是否为同一个，因此可能造成小区容量的浪费或欠缺；2)当前小区的网络负载较高，微基站启动小小区，但网络负载即将开始下降，之后微基站再次关闭小小区；或者当前小区的网络负载较低，微基站关闭小小区，但网络负载即将增加，微基站还需要再次启动小小区，从而导致小小区的频繁启停，降低用户体验和网络能效。其中，关闭小小区时还可以通过关闭微基站的方式实现相同的效果。
综上所述，现有控制微基站和/或小小区启停时判断方式单一，准确性低，可能造成频繁启停从而降低网络能效。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述，显然，所描述的实施例仅仅是本申请一部份实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本申请保护的范围。
下面对文中出现的一些词语进行解释：
1、本申请实施例中术语“和/或”，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。字符“/”一般表示前后关联对象是一种“或”的关系。
2、本申请实施例中术语“多个”是指两个或两个以上，其它量词与之类似。
3、本申请实施例中术语“小小区”是指由小基站提供覆盖的小区。
本申请实施例描述的应用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，随着新应用场景的出现，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。其中，在本申请的描述中，除非另有说明，“多个”的含义是两个或两个以上。
目前，网络密集化的程度越来越重，为了节能降耗，接入网设备会根据网络负载状况关闭一些具有信号重复覆盖且负载较低的小区或基站，当网络负载较高时，再激活该小区或启动相应的基站，然后目前控制小区或基站启 停的方式比较单一，造成了小区或基站的频繁启停，严重影响了网络性能，给用户带来不良的使用体验。为了避免小区或基站的频繁启停，本申请实施例结合了网络负载趋势的分析和预测，根据当前网络负载情况和之后一段时间的网络负载变化趋势来决定是否关闭或启动小区及基站，提高了控制精度，避免了小区或基站的频繁启停。
对于网络负载趋势的分析和预测，本申请实施例基于支持网络数据分析功能的5G PCC网络架构，其中5G PCC的基本网络架构的示意图如705所示。下面对支持网络数据分析功能的5G PCC网络架构进行介绍说明：
首先，对5G PCC网络架构中的各节点进行解释：
1，NWDAF实体(Network data analytic function，网络数据分析功能)具有网络数据分析功能，能够提供网络切片相关的网络数据分析。
2，(R)AN((Radio)Access Network,(无线)接入网)：可以是3gpp的接入网(如LTE、5G-NR)，也可以是non-3gpp的接入网(如常见的wifi接入)；
比如：若UE(User Equipment，用户设备)为手机，当使用手机上网时，(R)AN节点就是基站。
3，UPF(User Plane Function，用户面功能)：用户面功能实体；最主要的功能是负责数据包的路由转发、Qos流映射。
4，AMF：接入和移动性管理功能实体是RAN信令接口(N2)的终结点，NAS(N1)信令(MM消息)的终结点，负责NAS消息的加密和完保、负责注册、接入、移动性、鉴权、透传短信等功能。
5，SMF(Session Management Function，会话管理功能)：会话管理功能实体；SMF的主要功能有：1)NAS(Non-access stratum，非接入层)消息的SM(Session Management，会话管理)消息的终结点；2)会话(session)的建立、修改、释放；3)UE IP(Internet Protocol Address，国际协议地址)的分配管理；4)为一个会话选择和控制UPF；5)计费数据的收集以及支持计费接口；6)下行数据指示；等等。
6，PCF(Policy Control Function，策略控制功能)：策略控制功能实体支 持统一的策略框架去管理网络行为，提供策略规则给网络实体去实施执行，访问统一数据仓库(UDR)的订阅信息，PCF只能访问和其相同PLMN的NDR。
7，NEF(Network Exposure Function，网络能力开放功能)：网络暴露功能实体；3gpp的网元都是通过NEF将其能力暴露给其它网元的。
8，UDR(Unified Data Repository，统一数据库)：1)UDM存储订阅数据或读取订阅数据；2)PCF存储策略数据或者读取策略数据；3)存储暴露的数据或者从中读取暴露的数据。
该网络架构还包括NSSF(Network Slice Selection Function，网络切片选择功能)、AF(Application Function，应用功能)和OCS(Online Charging System，在线计费系统)。
本申请实施例中网络侧设备可以通过AMF向NWDAF实体订阅网络负载预测分析，网络侧设备在进行小区管理时，根据NWDAF实体的分析预测结果确定是否要关闭或启动小区以及对应的基站。
下面结合说明书附图对本申请实施例做进一步详细描述。
如图4所示，本申请实施例提供的是一种小区管理的系统，该系统包括：网络数据分析功能实体10和网络侧设备20。
网络数据分析功能实体10，用于接收到网络侧设备发送预测请求信息；根据预测请求信息，对终端的移动性信息和终端的通信信息中的至少一个以及网络的小区负载进行分析和预测；将生成的小区负载变化趋势预测信息或小区启停控制建议信息发送给网络侧设备，以使所述网络侧设备根据所述小区负载变化趋势预测信息或小区启停控制建议信息进行小区管理。
网络侧设备20，用于向网络数据分析功能实体发送预测请求信息；根据接收到的所述网络数据分析功能实体发送的小区负载变化趋势预测信息或小区启停控制建议信息进行小区管理。
通过上述方案，网络数据分析功能实体接收到网络侧设备发送的预测请求信息后，根据预测请求信息对终端的移动性信息和终端的通信信息中的至少一个以及网络的小区负载进行分析和预测，生成小区负载变化趋势预测信 息或小区启停控制建议信息，网络侧设备能够根据小区负载变化趋势预测信息或小区启停控制建议信息控制相关区域的小区或基站的启动和停止，以此实现小区管理，避免单纯依靠小区当前负载控制小区时可能造成的小区频繁启停，提高了控制小区启停的准确性和网络能效。
本申请实施例中，NWDAF实体接收到网络侧设备发送的请求信息后，根据请求信息确定需要进行分析和预测的对象信息，其中，请求信息中包括指定区域信息、指定基站信息、指定小区信息中的至少一个，以及预测时间信息，假设网络侧设备发送的请求信息包含指定小区信息，则NWDAF实体需要搜集指定小区的基站负载信息、基站服务的用户的终端移动性信息和/或终端通信信息，并根据搜集到的信息对预测时间段内的指定小区的网络负载进行分析和预测，并将得到的预测结果通知给网络侧设备。
其中，NWDAF实体接收到的请求信息的类型有多种，具体包括：小区负载预测请求信息和小区启停控制预测请求信息，NWDAF实体根据接收到的请求信息的类型反馈相应的预测结果，下面进行举例说明：
方式一：请求信息为小区负载预测请求信息；
网络侧设备发送小区负载预测请求；
NWDAF实体接收到小区负载预测请求信息，则NWDAF实体的预测结果为小区负载变化趋势，NWDAF实体将小区负载变化趋势预测信息通知给网络侧设备，其中，小区负载变化趋势预测信息可以是数字、文字或图表等形式的体现。
对应的，网络侧设备接收到小区负载变化趋势信息后，结合小区当前的负载和小区负载变化趋势判断是否需要在预测时间内开启该小区或该小区对应的基站，或者关闭该小区或该小区对应的基站，以实现对小区的管理。
方式二：请求信息为小区启停控制预测请求信息；
网络侧设备发送小区启停控制预测请求；
NWDAF实体接收到小区启停控制预测请求信息，则NWDAF实体的预测结果为小区启停控制建议，NWDAF实体将小区启停控制建议信息通知给 网络侧设备，其中，小区启停控制建议信息包括：需要关闭的小区和/或该小区对应的基站、需要开启的小区和/或该小区对应的基站。
对应的，网络侧设备接收到小区启停控制建议信息后，根据小区启停控制建议信息开启相应的小区或基站以及关闭相应的小区或基站，以实现对小区的管理。
需要说明的是，网络侧设备有多种，网络侧设备可以是基站或者核心网设备，该核心网设备为具备移动性管理功能和会话管理功能的设备，比如：结合图3的5G PCC网络架构，该核心网设备可以是AMF设备。其中，若网络侧设备为基站，基站向NWDAF实体发送用于进行小区管理所需的网络负载分析预测的请求信息；或网络侧设备为AMF设备，AMF设备辅助接入网设备(如基站)进行小区管理，由AM设备F向NWDAF实体发送请求信息，向订阅NWDAF实体相关的服务。
另外，目前，运营商根据网络运营的实际需要，将网络的管理工作划分为3大类，分别为：操作(Operation)、管理(Administration)、维护(Maintenance)。操作管理维护设备可以完成日常网络和业务进行的分析、预测、规划和配置工作；其中，配置工作也包含小区或基站的启停控制的配置，因此具备操作管理维护功能的设备(简称操作管理维护设备)为了精准的进行小区管理，也可以向NWDAF实体发送请求信息，获取网络负载的分析预测信息。
综上，网络侧设备可以是操作管理维护设备、基站和核心网设备中的一种，不同的网络侧设备对于预测结果的处理也有所区别。
下面以AMF为例，通过具体实施例对网络侧设备为核心网设备时进行小区管理的方案进行说明：
实施例1：网络侧设备为AMF；
如图5所示，为AMF和NWDAF实体组成的进行小区管理的系统之间的交互流程示意图，主要包括以下步骤：
步骤500，AMF向NWDAF实体发送预测请求信息，向NWDAF实体订阅小区负载预测信息或小区启停控制建议预测信息；其中，预测请求信息中 包含待分析的小区信息或待分析的基站信息或待分析的区域信息以及预测时间等信息；其中，预测时间信息可以是某具体的时间段或是固定的时间长度等，进一步的，该预测时间信息还可以是周期性的时间信息，NWDAF实体每隔固定的时间长度向AMF反馈分析预测结果。
步骤501，NWDAF实体接收到AMF发送的预测请求信息后，根据预测请求信息携带的指示信息确定待分析的对象以及需要预测时间段，比如：该预测请求为小区负载预测请求信息，该请求信息携带的指示信息为预测时间20min，指定对象为指定小区，则NWDAF实体需要对接收到预测请求信息后的或网络侧设备发送预测请求信息后的20min内，该指定小区的网络负载变化趋势进行分析和预测；
NWDAF实体为了得到较为准确的分析预测结果，需要搜集获取指定对象的信息，比如：若指定对象为指定区域，则NWDAF实体获取指定区域内的终端的移动性信息和/或终端的通信信息以及指定区域内的小区的小区负载信息；或若指定对象为指定基站，则NWDAF实体获取指定基站服务的终端的移动性信息和/或终端的通信信息以及该基站下的小区的小区负载信息；或若指定对象为指定小区，则NWDAF实体获取指定小区覆盖的终端的移动性信息和/或该小区覆盖内的终端的通信信息以及该小区的小区负载信息。
NWDAF实体根据搜集到的终端的移动性信息对终端在预测时间内的位置进行预测；以及根据获取到的终端的通信信息对终端在预测时间内的流量模型，流量大小，流量速率的进行预测，根据终端的移动性预测信息和通信预测信息以及指定对象的小区负载信息对该指定对象在未来20min内的负载变化趋势进行分析和预测，并将预测结果通知给AMF；
需要说明的是，若预测请求信息携带的为指定区域信息，则NWDAF实体需要获取指定区域内的终端的移动性信息和/或指定区域内的终端的通信信息，根据获取到的信息进行分析和预测；若预测请求信息携带的为指定基站信息，则NWDAF实体需要获取指定基站服务的终端的移动性信息、指定基站服务的终端的通信信息和指定基站下的小区负载中的至少一个进行分析和 预测。
其中，NWDAF实体获取信息的方式有多种，比如：NWDAF实体向向核心网设备获取；具体流程包括：NWDAF实体向AMF发送获取终端的移动性信息和/或终端的通信信息以及网络的小区负载的请求，以及NWDAF实体接收AMF反馈的信息。或
NWDAF实体向操作维护管理设备获取，具体流程包括：NWDAF实体向操作维护管理设备发送获取终端的移动性信息和/或终端的通信信息以及小区负载的请求，以及NWDAF实体接收操作维护管理设备反馈的信息。
步骤502，NWDAF实体根据预测时间段内终端的移动性预测信息和/或终端的通信预测信息以及小区负载信息，对预测时间段内的小区的负载变化趋势或者小区的启停控制进行分析和预测，并将预测信息通知给AMF设备；
步骤503，AMF设备接收到预测信息后，将指定区域或指定小区或指定基站服务区域的负载变化趋势的预测信息通知给指定的基站，若该指定基站与AMF没有直接的信令连接，则AMF设备可以将预测信息通知给予该指定基站相邻的宏基站上。
其中，AMF设备对于接收到的预测信息的处理方式有多种，下面进行举例说明：
处理方式一：将接收到的预测信息直接通知给指定基站；
AMF设备接收NWDAF实体发送的小区启停控制建议信息或小区负载变化趋势预测信息后，将小区启停控制建议信息或小区负载变化趋势预测信息发送给指定基站；
处理方式二：根据接收到的小区负载变化趋势预测信息生成小区启停控制建议信息；
AMF设备接收NWDAF实体发送的小区负载变化趋势预测信息后，根据小区负载变化趋势预测信息生成小区启停控制建议信息，并将小区启停控制建议信息通知给指定的基站。
其中，根据小区负载变化趋势生成小区启停控制建议信息时，若小区负 载变化趋势为上升趋势，则确定该小区需要启动；若小区负载变化趋势为下降趋势，则确定该小区可以关闭；或若小区负载和小区负载上升率都超过小区开启阈值，则确定该小区需要开启；若小区负载未达到开启阈值，且小区负载下降率达到关闭阈值，则确定该小区需要关闭，具体生成小区启停控制建议信息的方式有多种，上述仅为举例，任何能够根据小区负载变化趋势以及能够体现小区负载变化趋势的信息生成小区启停控制建议信息的方式都适用于本申请。
步骤504，基站接收AMF设备发送的小区启停控制建议信息，根据接收到的小区启停控制建议信息开启或关闭指定的小区和/或基站；或基站接收AMF发送的小区负载变化趋势预测信息，根据小区负载变化趋势预测信息生成小区启停控制建议信息，根据生成的小区启停控制建议信息开启或关闭指定的小区和/或基站。
基站通过AP(Access Point，接入点)实现与指定基站之间的通信；比如：小区启停控制建议信息指示该基站需要激活邻基站的小区，则通过AP向邻基站发起如图2所示的小区激活过程。
实施例2：网络侧设备为基站；
如图6所示，为基站和NWDAF实体组成的进行小区管理的系统之间的交互流程示意图，主要包括以下步骤：
步骤600，基站向NWDAF实体发送预测请求信息，向NWDAF实体订阅小区负载预测信息或小区启停控制建议预测信息；
步骤601，NWDAF实体接收到基站发送的预测请求信息后，根据预测请求信息携带的指示信息确定待分析的对象以及需要预测时间段，向操作维护管理设备或AMF设备搜集指定对象相关的终端的移动性预测信息和/或终端的通信预测信息以及小区负载信息；
步骤602，NWDAF实体根据预测时间段内终端的移动性预测信息和/或终端的通信预测信息以及小区负载信息，对预测时间段内的小区的负载变化趋势或者小区的启停控制进行分析和预测；
步骤603，NWDAF实体将分析或预测结果通知给基站；
步骤604，基站根据预测信息执行相应的操作，比如：若预测信息为小区负载变化趋势预测信息，则基站根据小区负载变化趋势预测信息生成小区启停控制信息，并根据生成的小区启停控制信息开启或关闭指定的小区和/或基站；或若预测信息为小区启停控制建议信息，基站根据该小区启停控制建议信息开启或关闭指定的小区和/或基站。
上述实施例介绍了基站与核心网侧的NWDAF实体通信进行小区管理的主要流程，进一步的，若接入网侧部署了NWDAF实体，则基站还可以通过接入网侧的NWDAF实体与核心网侧的NWDAF实体进行通信，获取进行小区管理的预测信息。下面以具体的实施例对基站通过接入网侧部署的NWDAF实体和核心网侧的NWDAF实体组成的进行小区管理的系统进行详细说明：
实施例3：基站、接入网侧部署的NWDAF实体和核心网侧的NWDAF实体组成进行小区管理的系统；
如图7所示，网络侧设备为基站，基站通过接入网侧部署的NWDAF实体与核心网侧的NWDAF实体组成的进行小区管理的系统之间的交互流程示意图，主要包括以下步骤：
步骤700，基站向接入网侧部署的NWDAF实体发送预测请求信息；其中，接入网侧部署NWDAF实体仅为举例，也可以是邻近接入网侧部署的NWDAF实体或者基站本地部署的NWDAF实体。
步骤701，接入网侧部署的NWDAF实体接收到基站发送的预测请求信息后，根据预测请求信息携带的指示信息确定待分析的对象以及需要预测时间段，向核心网侧的NWDAF实体订阅预测时间段内指定对象对应的终端的移动性预测信息和/或终端的通信预测信息以及小区负载信息；其中，指定对象为指定区域、指定小区或指定基站。
步骤702，核心网侧的NWDAF实体向操作维护管理设备或AMF设备搜集指定对象的终端的移动性信息和/或终端的通信信息以及网络的小区负载，根据搜集到的信息生成终端的移动性预测信息和/或终端的通信预测信息以及 小区负载信息，并将生成的终端的移动性预测信息和/或终端的通信预测信息以及小区负载信息发送给接入网侧的NWDAF实体。
步骤703，接入网侧的NWDAF实体预测时间段内终端的移动性预测信息和/或终端的通信预测信息以及小区负载信息，对预测时间段内的小区的负载变化趋势或者小区的启停控制进行分析和预测；
步骤704，NWDAF实体将分析或预测结果通知给基站；
步骤705，基站根据预测信息执行相应的操作，比如：若预测信息为小区负载变化趋势预测信息，则基站根据小区负载变化趋势预测信息生成小区启停控制信息，并根据生成的小区启停控制信息开启或关闭指定的小区和/或基站；或若预测信息为小区启停控制建议信息，基站根据该小区启停控制建议信息开启或关闭指定的小区和/或基站。
需要说明的是，上述仅为举例，生成预测信息的可以是接入网侧的NWDAF实体，也可以是核心网侧的NWDAF实体。
实施例4：网络侧设备为操作维护管理设备；
如图8所示，为操作维护管理设备和NWDAF实体组成的进行小区管理的系统之间的交互流程示意图，主要包括以下步骤：
步骤800，操作维护管理设备向NWDAF实体发送预测请求信息，向NWDAF实体订阅小区负载预测信息或小区启停控制建议预测信息；
步骤801，NWDAF实体接收到操作维护管理设备发送的预测请求信息后，根据预测请求信息携带的指示信息确定待分析的对象以及需要预测时间段，向操作维护管理设备或AMF设备搜集指定对象相关的终端的移动性预测信息和/或终端的通信预测信息以及小区负载信息；
