具体实施方式
下文中将结合附图对本申请的实施例进行说明。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。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
本申请的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LIE-A(Advanced long term evolution，先进的长期演进)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、以及第五代(5th generation，5G)移动通信系统等，本申请实施例并不限定。在本申请中以5G系统为例进行说明。
本申请实施例中，基站可以是能和用户设备通信的设备。基站可以是任意一种具有无线收发功能的设备。包括但不限于：基站(NodeB，NB)、演进型基站(evolved NodeB，eNodeB或eNB)、5G通信系统中的基站、未来通信系统中的基站、WiFi系统中的接入节点、无线中继节点、无线回传节点等。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；基站还可以是小站，传输节点(transmission reference point，TRP)等，本申请实施例并不限定。
下一代无线接入网络(the Next Generation-Radio Access Network，NG-RAN)基站(下一代基站(the next Generation NodeB，gNB)或下一代演进型基站(thenext generation-evolved NodeB，ng-eNB))通过标准化的NG接口和5G核心网(5G Core，5GC)连接，包括NG-C(Next Generation-Control Plane，下一代控制面)连接和NG-U(Next Generation-User Plane，下一代用户面)连接。NG-C是5G核心网元控制面连接，用于信令传输；NG-U是5G核心网元用户面连接， 用于用户数据传输。NG-RAN基站(gNB或ng-eNB)彼此之间通过Xn接口连接，包括Xn-C(Xn-Control Plane，NG-RAN基站间控制面)连接和Xn-U(Xn-UserPlane，NG-RAN基站间用户面)连接。图1为分离式(Disaggregated)NG-RAN基站gNB集中单元(Centralized Unit，CU)/分布单元(Distributed Unit，DU)空口协议栈分离情况下的架构图。以3GPP(The third Generation Partnership Project，第三代合作伙伴计划)协议的gNB-CU/DU分离为例，单个gNB被分离为单个gNB-CU和多个gNB-DU。gNB-CU和gNB-DU之间通过标准化的F1接口相互连接，包括F1控制面(F1-Control Plane，F1-C)连接和F1用户面(F1-UserPlane，F1-U)连接。CU/DU分离后的gNB/ng-eNB和不分离的gNB/ng-eNB对外的接口均是NG接口和Xn接口。上述各个网络接口的控制面连接用于传输网络节点之间的控制信令消息，用户面连接用于传输用户业务数据(包)。NGAP(Next Generation Application Protocol，下一代应用协议)、XnAP、F1AP分别为NG-C的RNL(Radio Network Layer，无线网络层)协议、Xn-C的RNL协议、F1-C的RNL协议。NAGP、XnAP、F1AP基于网络下层TNL(Transport Network Layer，传输网络层)传输承载(例如SCTP连接)来传输对应接口上的控制信令。NG-U、Xn-U、F1-U用户面接口的用户业务数据帧，基于网络下层的TNL传输承载(例如GTP-U隧道)来传输对应接口上的用户业务数据(包)。SCTP为流控制传输协议(Streaming Control Transport Protocol)，GTP为GPRS隧道协议(GPRS Tunnel Protocol)。
当终端例如UE与NG-RAN基站处于RRC(Radio Resource Control，无线资源控制)连接状态时，核心网的接入和移动性管理功能(Access and Mobility Management Function，AMF)可向NG-RAN基站请求上报UE在主基站侧的位置信息，简称ULI(User Location Information，用户位置信息)。这样，可以使得核心网感知到UE在异构大网络中的小区级的位置。与通过各种定位(Positioning)手段获得UE精准的地理位置信息不同，ULI的最小精度为服务小区。AMF感知到UE的ULI，便于针对该UE的不同位置做差异化的策略配置和处理。举例而言，AMF可向NG-RAN基站请求上报UE的ULI。例如：请求直接上报(report directly)UE当前正驻留的服务小区信息；请求当UE发生服务小区变化时再上报目标服务小区信息(report upon change of serving cell)；请求当UE进入特定AOI(Area of Interest，兴趣区域)时上报目标AOI信息(report upon UE presence in the area of interest)等。
如上所述，在5G网络中的RRM功能都是小区粒度的，即服务小区内所有UE都执行相同的RRM策略。但同一个服务小区内的不同区域的邻区覆盖和性能是存在差异的，更合理的处理应该是为不同邻区覆盖特性下的UE实行不同的RRM策略。因此，需要对服务小区进行进一步地划分，即栅格粒度的划分。栅 格，即为通过测量得到UE当前所处环境下多个同频小区的信号情况，然后根据服务小区和信号质量的不同进行的区域划分，是一种不同于以往基于地理位置信息划分的空间划分方法。通过统计每个栅格内的无线特性(如邻区覆盖等)，可以实现更精细化的网络策略部署。
通过5G网络中不同网元之间栅格级别的信息交互，可以更好地完善网络中的自优化功能。同时，随着AI和机器学习技术的引入，基于栅格粒度的网络划分，可以更好地完成对于网络的信息预测和结构部署。
图2为本申请实施例提供的一种消息接收方法的流程示意图。该方法可以适用于根据栅格进行不同区域划分的情况。该方法可以由本申请提供的消息接收装置执行，该消息接收装置可以由软件和/或硬件实现，该方法应用于第一网元上。
如图2所示，本申请实施例提供的消息接收方法主要包括步骤S11、S12和S13。
S11、发送请求消息至第二网元，所述请求消息用于指示第二网元发送请求确认消息。
S12、接收所述第二网元发送的请求确认消息，所述请求确认消息携带目标小区的栅格信息。
S13、根据所述请求确认消息携带的目标小区的栅格信息更新第一网元的栅格信息。
在本实施例中，所述第一网元可以包括上述任意一种基站。在第一网元是上述任意一种基站的情况下，第二网元是与第一网元相同或者不同的基站。
在另一个实例中，在5G基站采用CU/DU分离架构的情况下，第一网元可以是5G基站中的集中单元CU。在第一网元是5G基站中的集中单元CU的情况下，第二网元是5G基站中的分离单元DU。
在一个示例性的实施方式中，发送请求消息至第二网元之前还包括：基于当前小区的栅格信息确定目标小区；根据所述目标小区确定第二网元。
在一个示例性的实施方式中，在第一网元和第二网元均是基站的情况下，请求消息是切换请求消息，请求确认消息是切换请求确认消息。
