Description

一种获取小区系统消息的方法及系统 技术领域
本发明涉及自动邻区管理技术， 尤其涉及一种获取小区系统消息的方 法及系统。 背景技术
随着蜂窝移动通信系统用户数的增多和用户服务需求的提高， 蜂窝网 络的规模不断扩大， 基站数不断增多， 各种制式的蜂窝移动通信系统不断 加深彼此协同操作。 相应的， 蜂窝网络中小区的邻区关系管理和维护成为 越来越繁瑣的工作， 运行商期望过去纯手工的邻区关系管理能够被系统自 动 4匕, 不例夕卜地 , UTRA ( UniversalTelecommunicationRadioAccess )网络运 行商也非常渴求其网络小区的邻区关系实现自动管理。
图 1为 UTRA系统架构示意图， 如图 1所示， 在 UTRA网络中， 通用 陆地无线接入网 （ Universal Terrestrial Radio Access Network, UTRAN ) 包 括无线网络控制器（ Radio Network Controller, RNC )和基站（ NodeB ) 两 种基本网元， 成百上千的 NodeB下众多小区间的邻区关系会随着网络规划 优化的需要和所处无线环境的变化而动态地变化。
在 UTRA网络中， 小区间正确的邻区关系对网络性能非常重要， 比如: 实现 UE最优切换、保证其服务连续性、帮助网络实现负载均衡、容量调配、 节能等多重目的。 过去纯手工邻区编排下， 网络侧将已提前配置好的邻区 关系通过系统广播消息或者专有控制消息通知给终端 UE, UE进一步存储 和利用这些收到的小区邻区关系。 但是， 这种来自网络侧提前配置好的邻 区关系可能是过时的， 不能真正反映实时的邻区关系， 从而可能造成 UE 错误切换， 甚至掉话， 网络性能总体下降。 在长期演进 ( Long Term Evolution , LTE ) 系统中， 已经实现了自动邻 区关系功能 ( Automatic Neighbor Relation Functionality, ANRF ) ,LTE 中 ANRF实现的主要思想为： 网络侧命令终端测量相邻检测小区（ detected set cell ) 的物理层信息并上报给网络侧， 如果网络侧尚无某上报小区的相邻关 系， 则命令终端读取此相邻检测小区的系统广播消息来获取并上报其层 2 信息， 最后， 网络侧基于上报的层 2信息， 补充和更新邻区关系列表。
UTRA网络中的 ANRF功能可能有多种实现方法， 其中之一就是模仿 上述 LTE中 ANRF的实现方法， 简称两步检测法， 图 2为 UTRA网络中 ANRF两步检测法的流程示意图， 如图 2所示， 该流程包括：
步骤 201： RNC通过测量控制消息（ Measurement Control )命令处于专 有连接态 （Cell_DCH ) 的 UE对相邻检测小区 （包括频内 Intra-frequency、 频夕卜 Inter-frequency、 系统外 Inter-RAT )进行物理层测量。
步骤 202: UE在测量控制消息指示下， 进行相应相邻检测小区测量， 获得目标检测小区的物理层信息， 如主扰码（PSC )、 主导频信道信号强度 ( CPICH RSCP )等。
步骤 203: UE通过测量 ^艮告消息（ Measurement Report ) 告测量结果。 步骤 204:基于所述 UE的物理层测量报告， RNC发现某相邻检测小区 尚未建立和当前服务小区邻区关系， 则再次下发 Measurement Control给之 前的 UE, 要求 UE再次对相邻检测小区进行系统消息读取， 以获得层 2信 息如小区全局标识 CGI。
步骤 205: UE根据 RNC下发的 Measurement Control,对指定小区进行 系统消息读取。
步骤 206： UE通过 Measurement Report上报指定小区的层 2信息。 步骤 207: RNC基于所述 UE上报的层 2信息维护当前服务小区的邻区 关系列表。 上述 UTRA系统 ANRF 两步检测法有以下缺点：
1、 必须由同一个 UE完成 ANRF任务中的两步。 这意味着如果 UE在 第一步结束后需要向目标小区进行切换， 则为了完成 ANRF任务中的第二 步， 该切换必须被延迟， 从而影响用户体验。
2、 如果 UE第二步系统消息读取失败， 则该 UE的 ANRF任务尝试失 败， 即该 UE第一步对相邻检测小区物理层的测量结果也就白费了。
对于上述缺点， UTRA 网络固然可以通过实现的方式进行规避， 但不 能排除其发生的可能， 比如， 为了避免上述缺点 1 , RNC可以不选择处在 小区边缘即将要切换的 UE去执行 ANRF任务， 仅仅选择处于非小区边缘 地域的 UE去执行 ANRF任务，但是，处于小区边缘的 UE有更大概率检测 到更多的相邻小区， 所以选择处于非小区边缘地域的 UE去执行 ANRF任 务不利于 ANRF性能； 再比如， RNC可以给 UE配置足够长的数据传输空 闲， 来使 UE更可靠地读取更多的指示小区的系统消息， 但如果该 UE处于 一个实时数据通话态， 太长的数据传输空闲必然影响到用户的业务感受， 而 RNC为了减轻对特定用户业务感受的影响为 UE配置尽可能短的数据传 输空闲的话， 会增加 UE第二步系统消息读取失败的可能性。
总而言之， 釆用现有 ANRF 两步检测法获取小区系统消息不利于用户 体验， 且获取成功率不高。 发明内容
有鉴于此， 本发明的主要目的在于提供一种获取小区系统消息的方法 及系统， 能够提高获取成功率， 且能保证用户体验。

网络侧判定需要获取小区的系统信息为：网络侧根据所述 UE返回的测 量结果，确定其中存在至少一个小区尚未建立与所述 UE当前服务小区的邻 区关系， 则判定需要获取该新发现小区的系统信息。
步骤 304: 网络侧选择用于获取小区系统信息的 UE ( UE2 )。
网络侧选择用于获取小区系统信息的 UE时， 一般在步骤 303所述 UE 返回测量结果时所在的小区中选择合适的 UE, 为了保证用户体验， 以及相 邻小区系统消息的获取成功率，选择的 UE应处在非实时（最好不是语音通 话、观看在线视频这些实时业务）且数据传输量较轻（ Non real time low data activity ) 的状态， 从而有着较多的数据传输空闲， 如不连续接收 DRX, 便 于有足够空隙去系统消息读取。
需要说明的是， 如果网络侧需要获取多个小区的系统信息， 可以相应 地命令多个 UE (如 UE2、 UE3、 UE4 )分担系统消息读取任务， 以提高系 统消息读取的成功率。
步骤 305 : 网络侧立即指示或间隔一段时间后指示所述选择的 UE ( UE2 )利用网络侧提供的合适的接收时隙或 UE自发开启的本地接收时隙 获取指定新发现小区的系统信息， 以获得用于邻区关系构建的层 2必要信 息。
这里， 网络侧可以通过 Measurement Control消息通知选择的 UE对指 定小区进行系统消息读取， 即所述 Measurement Control消息携带指定小区 信息， 所述指定小区信息可以仅包括指定小区的物理层区分标识， 也可以 包括指定小区的其他标识信息，如步骤 303中 UE返回的测量结果中的相关 信息。
需要说明的是，指定的小区即步骤 303所述未建立与所述 UE当前服务 小区的邻区关系的小区，网络侧如何根据步骤 303中 UE返回的测量结果指 定小区为现有技术， 在此不作详细介绍。
步骤 306: 所述选择的 UE ( UE2 )根据网络侧指示获取所述指定小区 的系统信息， 并将获取的用于邻区关系构建的层 2必要信息返回网络侧。
需要说明的是，所述选择的 UE获取指定小区的系统信息失败时， 网络 侧指示所述选择的 UE重新获取指定小区的系统信息，或者，重新选择其他 UE来获取指定小区的系统信息， 直到成功地获取邻区构建所需层 2信息。
需要说明的是， 上述 UE1 , UE2是逻辑上的意义， 当物理上是同一个 物理 UE的时候， 也就回落成现有的方案。
可以看出， 通过本发明， UE1的切换过程和为 ANRF而所需的系统消 息读取过程相分离， UE1不必完成系统消息读取， 而 UE2、 UE3这些终端 的系统消息读取， 也不依赖自己必须先去进行小区的物理层测量， 可以借 助于 UE1之前的小区的物理层测量结果， 并且， UE2如果一次不能正确读 取指示小区的系统消息， 网络侧可以命令 UE2第二次重读， 或者让其他终 端如 UE3来重读。 从而网络侧能够在保证终端 UE移动性能、 业务感受等 方面影响很小的同时， 更加灵活地去进行 ANRF, 提高 RNC对小区系统消 息的读取成功率。
本发明还相应地提出一种获取小区系统消息的系统， 该系统包括： 网 络侧和 UE; 其中，
所述网络侧，用于指示移动状态的 UE或强制非移动状态的 UE进行相 邻小区物理层测量， 并接收所述 UE返回的测量结果， 以及在根据所述接收 的测量结果判定需要获取小区的系统信息时， 选择用于获取小区系统信息 的 UE, 并立即指示或间隔一段时间后指示所述选择的 UE利用网络侧提供 的合适的接收时隙或 UE 自发开启的本地接收时隙获取指定小区的系统信 息；
所述 UE, 用于根据网络侧的指示进行小区物理层测量， 并返回测量结 果； 和 /或， 根据网络侧的指示获取所述指定小区的系统信息， 并将获取的 系统信息返回网络侧。
所述网络侧判定需要获取小区的系统信息为：网络侧根据所述 UE返回 的测量结果， 确定其中存在新发现的相邻小区， 且网络侧没有所述新发现 的相邻小区用于邻区关系构建的层 2相关信息， 则判定需要获取所述新发 现的相邻小区的系统信息。
所述网络侧选择用于获取小区系统信息的 UE为： 网络侧在所述 UE返 回测量结果时所在的小区中， 选择处于非实时且数据传输量较轻的状态的
UE, 用于获取小区系统信息。
所述网络侧， 还用于在所述选择的 UE获取指定小区的系统信息失败 时， 指示所述选择的 UE重新获取指定小区的系统信息， 或者， 重新选择其 他 UE来获取指定小区的系统信息，直到成功地获取邻区构建所需层 2信息。
所述网络侧为无线网络控制器。
下面通过具体实施例对本发明的技术方案作进一步详细描述。 这里仅 仅举了频内做 ANRF的例子， 同理， 发明思想可以广泛用于频外， 系统外 的 ANRF场景。
实施例 1
本实施例中， UTRA小区 A内 UE1、 UE2都具备 ANRF的能力， 即能 够解析和执行 RNC下发的 Measurement Control中关于 ANRF的内容。 UE1 处于小区 A的边缘， 处于语音通话状态， 即将进行同频软切换； UE2处于 小区 A的非边缘区域， 处于数据不连续接收 DRX状态。
图 4为本发明实施例 1获取小区系统消息的方法流程示意图， 如图 4 所示， 该方法包括：
步骤 401 : RNC通过测量控制消息 （Measurement Control )命令 UE1 进行频内监测集小区物理层测量， 和对频内相邻检测小区的物理层测量， 从而获得目标检测小区的物理层信息， 如主扰码（PSC )、 主导频信道信号 强度（CPICH RSCP )等。 测量控制消息中的信元设置按照目前 3GPP协议 规范的去做。
步骤 402: UE在 Measurement Control指示下， 进行频内监测集和检测 集小区物理层测量。
步骤 403: UE通过测量 ^艮告消息（ Measurement Report ) 4艮告物理层测 量结果。测量报告消息中的信元设置按照目前 3GPP协议规范的去做。 RNC 要存储 UE上报的物理层测量结果， 特别是 PSC等目标检测小区关键指示 信息。
步骤 404: 基于上面 UE的物理层测量报告， RNC对 UE1进行相应的 同频软切换过程。 同频软切换过程按照目前 3GPP协议规范的去做。
步骤 405: 如果 RNC发现某同频相邻检测小区尚未建立和当前服务小 区邻区关系， 就把之前存储的 UE 上报的物理层测量结果， 通过下发 Measurement Control给 UE2 , 要求 UE2对指定的相邻检测 d、区进行系统消 息读取， 以获得层 2信息如小区全局标识 CGI。
需要说明的是， UE2 的选择是 RNC 内部 RRM ( Radio Resource Management ) 的工作， RRM 总是选择地理位置， 通信状态最合适的 UE2 去进行相邻检测小区系统消息读取， 前提是 UE2也能够检测到目标小区的 物理层信号。
步骤 406: UE2按照 RNC下发的 Measurement Control,对指定小区 PSC 进行系统消息读取。 系统消息读取流程按照目前 3GPP协议规范的去做。
步骤 407: UE2通过 Measurement Report上^艮指定小区 PSC的层 2信 息。具体的层 2信息可以由网络侧定制 ,如 Cell Identity, LAI、 RAC、 PLMM 等。
步骤 408: 基于 UE2的层 2信息测量报告， RNC维护当前服务小区的 邻区关系列表。
以上所述， 仅为本发明的较佳实施例而已， 并非用于限定本发明的保 护范围。
