Description

小区识别方法和装置
技术领域 本发明实施例涉及通信技术， 尤其涉及一种小区识别方法和装置。 背景技术
在现有移动通信网络中， 可以存在两种不同的网络节点， 这些网络节点 可以分别为一个或多个小区服务。宏基站（Marco eNB )下的宏小区覆盖的范 围较大， 小小区节点 （Small Cell Node, SCN ) 下的小区覆盖的范围较小; 在 一个宏小区的覆盖范围内或附近可能存在一个或多个覆盖漏洞或者业务热点 区域，可以釆用一个或多个小小区对这些覆盖漏洞或业务热点区域进行补偿， 从而增加系统带宽。
每个网络节点覆盖的小区可能具有两种标识， 分别为物理小区标识 ( Physical Cell Identifier , PCI )和小区全局标识（ Cell Global Identifier , CGI ) , 网络中一共提供 504个不同的 PCI, 因此使用 PCI可以最多区分 504个小区。 当网络中小区的数量多于 504个时， 就会存在两个或两个以上的小区共享一 个 PCI,此时使用 PCI不能唯一确定一个小区。而网络中提供的 CGI有 228个， 因此每个小区都具有与其他小区不同的 CGI, 使用 CGI可以唯一确定一个小 区。
当一个宏小区的覆盖范围内及其附近的小区的数量大于 504个的时候， 宏基站根据 PCI可能无法唯一确定这些小区， 从而无法和这些小区所属的通 信节点进行后续的通信， 这些小区成为待识别小区， 这种情况可以称为 PCI 混淆。
当出现 PCI混淆时， 需要通过用户设备上报待识别小区的 CGI可以让第 一网络节点唯一确定该待识别小区。 用户设备需要通过读取该待识别小区的 系统信息才能获得该待识别小区的 CGI, 这要求待识别小区的系统信息需要 始终处于广播状态， 总是广播系统信息会增加待识别小区节点的耗电量， 并 且增加了系统内的干扰。 发明内容 本发明实施例提供一种小区识别方法和装置， 用于节约网络节点的耗电 量， 并避免由于网络节点持续广播系统信息而增加的系统干扰。

本发明实施例中， 第一网络节点可以为演进基站 （E-UTRAN NodeB, eNB ) , 也可以是长期演进网络中的家庭基站网关 （HeNB GW, Home eNB Gateway ) , 通用移动通信网络中的家庭基站网关（ HNB GW , Home NodeB Gateway ) , 基站（UTRAN NodeB, NB ) 、 施主基站（Donor eNB, DeNB ) 或者宏基站等功率和覆盖范围都较大的网络节点。 第二网络节点可以为小小 区节点（ Small Cell Node, SCN )、小基站（ Micro (e)NB ) ,微基站（ Pico (e)NB )、 家庭节点（Home (e)NodeB, 也称 Femto ) 、 中继节点（Relay Node )和 WiFi 接入点等功率和覆盖范围都较小的网络节点， 可以是演进基站 （E-UTRAN NodeB, eNB ) , 也可以是一种特殊的用户设备。
图 1为一种小区的 PCI发生混淆时进行小区识别的信令流程图， 如图 1 所示， 该过程包括：
步骤 S101 , 第一网络节点向用户设备发送重配消息， 该重配消息用于指 示用户设备根据小区测量配置进行小区测量。 具体地， 第一网络节点可以根据该重配消息中包含小区测量配置测量待 识别小区的频率、 参考信号的接收功率或参考信号接收质量等。
步骤 S102, 用户设备向第一网络节点发送测量 4艮告。
具体地， 用户设备进行小区测量， 在满足上报条件（例如， 对于 A1事件 对应 A1测量报告的上报条件； 对于 B1事件对应 B1测量报告的上报条件； 等等）时向第一网络节点发送测量报告，该测量报告中包含待识别小区的 PCI。
步骤 S 103 , 第一网络节点再次向用户设备发送重配消息。
具体地，第一网络节点接收到用户设备发送的满足上报条件的小区的 PCI 后， 如果第一网络节点无法根据 PCI确定用户设备发送的满足上报条件的小 区为哪一个小区时（例如多个小区共享同一个 PCI, 用户设备在进行小区测 量时将这多个小区中待识别小区所对应的 PCI发送给基站， 基站在这种情况 下不能根据这个 PCI来判断用户设备上报的是这多个小区中的哪个或哪些）， 第一网络节点再次向用户设备发送重配消息， 该重配消息用于请求用户设备 读取用户设备发送的满足上报条件的小区的 CGI, 这些 CGI可以携带在系统 信息中。
步骤 S104, 用户设备读取待识别小区的系统信息中包含的 CGI。
具体地， 用户设备从第二网络节点所服务的待识别小区的系统信息中读 取 CGI。 由于第二网络节点无法得知何时用户设备需要获得系统信息， 第二 网络节点需要持续广播系统信息， 用户设备才能在需要获得待识别小区的 CGI时获得待识别小区的 CGI。
步骤 S105, 用户设备再次向第一网络节点发送测量报告， 该报告中包含 该待识别小区的 CGI , 第一网络节点才艮据该 CGI确定该待识别小区。
具体地， 用户设备获得上述待识别小区的 CGI后， 再次向第一网络节点 发送测量报告， 该测量报告中包含上述待识别小区的 CGI, 则第一网络节点 可以根据该 CGI唯一确定该待识别小区。
在图 1 所示的小区识别的方法中， 当第一网络节点用户设备上报的待识 别小区的 PCI与其他小区发生混淆时， 第一网络节点会再次要求用户设备上 报待识别小区的 CGI, 其才能根据该 CGI唯一确定该待识别小区。 但为了使 用户设备获得到待识别小区的 CGI, 第二网络节点需要持续广播系统信息， 该系统信息主要是为空闲用户设备所使用， 并不在业务通信过程中使用， 并 且持续广播该系统信息会增大第二网络节点的耗电量， 也会增加对整个通信 系统的干扰。 更进一步， 图 1所示的小区识别的方法， 用户设备读取到待识 别小区的 CGI后上报给第一网络节点， 这个过程有时会存在较长的时延， 第 一网络节点可能由于不能及时辨识出待识别小区而影响正常业务通信， 而降 低了用户体验。 图 2为本发明实施例一提供的小区识别方法的流程示意图， 如图 2所示， 本实施例为第一网络节点执行的操作， 本实施例的方法包括：

可选地， 步骤 301-306 中， 也可以将用户设备标识替换为 C-RNTI (该

应用本发明实施例二提供的技术方案， 并不需要第二网络节点持续广播 系统信息使用户设备通过接收第二网络节点广播的系统信息来获得小区的 CGI, 从而对待识别小区进行识别。 本发明实施例提供的技术方案中， 第一 网络节点需要辨识待识别小区时才触发用户设备与第二网络节点交互， 不仅 可以准确辨识出待识别小区， 尤其是在待识别小区的 PCI发生混淆时仍然可 以辨识该待识别小区， 可以节约第二网络节点的耗电量， 并且还可以避免由 于第二网络节点持续广播系统信息而增加的系统干扰。 图 4为本发明实施例三提供的一种小区识别方法的流程示意图， 本发明 实施例三是对实施例一的进一步细化， 包括以下内容。
S401 , 第一网络节点向用户设备和第二网络节点发送第一信息， 该第一 信息用于指示所述用户设备和所述第二网络节点根据参考信号 RS 的相关参 数确定所述第二信息， 该第二信息用于指示待识别小区。
例如， 所述 RS的相关参数包括 RS的标识、 RS的天线端口数、 RS的时 频资源配置、 RS的功率配置、 RS的扰码配置、 RS的发送带宽、 RS的发送 周期、 RS的发送起始点或 RS发送一次所持续的时间等等。 。
可选地， RS的相关参数可以由第一网络节点为用户设备和第二网络节点 分配， 也可以是用户设备和第二网络节点预置的； 该 RS 的相关参数与第二 网络节点对应， 使用该 RS 的相关参数的用户设备可以接收到第二网络节点 或者第二网络节点下小区发送的 RS;如果用户设备没有使用与第二网络节点 对应的 RS 的相关参数， 则接收不到第二网络节点或第二网络节点下小区发 送的 RS。
S402，如果用户设备使用 RS的相关参数从第二网络节点接收到了该 RS , 则用户设备将该 RS的相关参数作为第二信息上报给第一网络节点。
作为一个示例， 第一网络节点通过第一信息向各个小区的服务通信节点 指示不同组 RS 的相关参数（第二网络节点或第二网络节点下的小区对应其 中一组 RS的相关参数 ) , 还将这不同组的 RS的相关参数发送给用户设备。 用户设备通过使用不同组的 RS的相关参数中的一组进行 RS的测量，如果没 有测量到 RS或者测量到的 RS不是由第二网络节点发送，则再使用不同组的 RS的相关参数的另一组， 直到使用的一组 RS的相关参数可以接收到从第二 网络节点接收到 RS。
S403 , 第一网络节点根据第二信息， 可以识别出该 RS 的相关参数对应 的小区是哪个小区或哪些小区， 这个小区或这些小区就是待识别小区。

S502,用户设备使用 RS的相关参数对第二网络节点发送的 RS进行测量， 并根据待识别小区的帧起始时间和用户设备当前服务小区的帧起始时间根据 计算出待识别小区的 RSTD , 该 RSTD为待识别小区的帧起始时间与用户设 备当前服务小区的帧起始时间的时间差。
S503 , 第一网络节点接收用户设备发送的第二信息， 该第二信息用于指 示待识别小区的 RSTD , 第一网络节点根据该 RSTD识别出待识别小区。
具体地， 第一网络节点可以通过与各个小区的服务通信节点 （包括第二 网络节点）预置或协商各个小区的帧起始时间， 使得各个小区和用户设备当 前服务小区之间的 RSTD不同， 这样待识别小区就唯一对应了一个 RSTD, 从而使得在第一网络节点根据接收到待识别小区的 RSTD 识别出待识别小 区。
类似的，本发明实施例中 RS可以替换成同步信号（ Synchronization Signal : SS )。 相应地， RS的相关参数替换成同步信号的相关参数， 该同步信号的相 关参数包括 SS的标识、 SS的天线端口数、 SS的时频资源配置、 SS的功率配 置、 SS 的扰码配置、 SS 的发送带宽、 SS 的发送周期、 SS 的发送起始点或 SS 发送一次所持续的时间等等。 相应地， RSTD 替换为同步信号时间差 ( Synchronization Signal Time Difference, SSTD ) 。 小区 只另 ll的过程与 S501-S504类似， 不再赘述。
