Description

自动邻区关系测量方法及系统 技术领域
本发明涉及一种自动邻区关系维护技术, 尤其涉及一种自动邻区关系 测量方法及系统。 背景技术
随着蜂窝移动通信系统运营商用户数量的增多和用户对服务需求不断 增加, 蜂窝网络的规模不断扩大, 基站数量也随之增多。 为满足各种通信 业务的通信需求, 各种制式的蜂窝移动通信系统不断加深着彼此间的协同 操作。 这样, 蜂窝网络中小区的邻区关系管理和维护也成为日渐繁瑣的工 作, 于是运行商特别期望过去纯手工的邻区关系配置管理能够自动化地实 现。
图 1 为 UTRA 系统架构示意图, 如图 1 所示, 在通用陆地无线接入 ( UTRA, Universal Terrestrial Radio Access ) 系统中, 通用陆地无线接入网 ( UTRAN, Universal Terrestrial Radio Access Network ) 包括无线网络控制 器(RNC, Radio Network Controller )和基站(NodeB )等基本网元。 众多 NodeB 下的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变化。
在 UTRA系统中, 小区间正确的邻区关系对网络性能来说非常重要。 邻区关系的正确配置对实现移动用户、 用户设备 ( UE, User Equipment )最 优切换, 保证服务连续性、 实现负载均衡、 容量调配、 节能等都相当重要。 在过去纯手工邻区配置及编排下, 网络侧将预先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 UE, UE进一步存储和利用这些小区 邻区关系。 但是, 这种来自网络侧预先配置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, 导致 网络性能总体下降。
在 UTRA 系统中, 第三代合作伙伴计划 (3GPP, The 3rd-Generation Partnership Project ) 已经在版本 10 ( ReleaselO ) 中引入了一种基于最大努 力完成方式(Best Effort to do ) 的自动邻区关系功能(ANRF, Automatic Neighbor Relation Functionality )。 截至当前, 3GPP版本 10中的自动邻区关 系 (ANR, Automatic Neighbor Relation )方案的实现流程、 架构, 以及实 现的相关细节已经基本确定并且公开。图 2为 UTRA系统中 ANRF 方案的 实现流程图, 如图 2所示, 版本 10中涉及的 ANRF方案借用了最小化路 测(MDT, Minimize Driving Test )技术的思想, 该方案也称为 Log ANR方 案, 其流程包括以下步驟:
步驟 201 , UE驻留在源 RNC下某源小区 (Source cdl, 或者称为当前 月良务小区 Serving cell )中。 源 RNC在源小区中选择某个合适的 UE去执行 某一类或者几类 ANR测量任务。 这里, ANR测量任务类型分为基本的四 类, 分别为: UTRA ANR频内测量(Intra-frequency ANR logging ), UTRA ANR频外测量( Inter-frequency ANR logging ),跨 LTE ANR测量( Inter-RAT LTE ANR logging ), 跨 GSM ANR测量( Inter-RAT GSM ANR logging )0 步驟 202, 源 RNC在源小区中向之前为执行 ANRF任务选定的 UE发 送含有 ANR测量控制配置参数的 RRC下行消息(DL Message with ANR Configurations , 截至目前的十办议规范^ 态, 可以是 Logged Measurement Configuration这条消息)。 这些 ANRF配置参数包括: ANR测量限时参数 ( ANR logging duration timer ), ANR 测量范围限制参数 ( ANR logging detection range ), 以及 Intra-frequency ANR logging, Inter-frequency ANR logging, Inter-RAT LTE ANR logging, Inter-RAT GSM ANR logging这四种 基本 ANR 测量类型相关的小区信号评估的参数(ANR logging absolute threshold, ANR logging relative threshold )。 UE保存这些 ANRF的配置参数, 以待进入到 ANR测量合适状态之后使用。
步驟 203 , UE经过一定的无线资源控制( RRC, Radio Resource Control ) 信令交互后,进入到了某个合适 ANR测量的状态,就使用之前保存的 ANRF 配置参数为某一或者几类的相邻未知检测小区的测量做准备。 适合做 ANR 测量的状态, 根据目前协议规范可以是空闲模状态(Idle mode )、 注册区级 寻呼态 URA_PCH, 小区级寻呼态 Cell_PCH等。
步驟 204, 由于 UE本身可能的移动性或者其他原因, UE—方面进行 非 ANR测量任务相关的常规的邻区列表内的小区测量任务, 为小区重选做 准备; 另一方面, UE按照之前的 ANRF配置, 执行着 ANRF—类或者几 类测量任务, 并且将满足 log条件的未知相邻检测小区 (包括物理层信息, 物理层之上的层 2信息等 )记录在 UE内部的 ANR log表( ANR Logging Table ) 中。 这种记录行为简称为 ANR Logging或者 Logging, 是指 UE做 完 ANR测量之后的记录动作。 当 UE常规的邻区列表内的某相邻小区满足 小区重选条件时, UE仍然按照以往的模式重选到那个邻区列表内的目标小 区中, 并不会受到 ANR测量的干扰, 也就是说 ANR测量任务是附带伴随 着 UE常规小区重选行为的, UE的小区重选性能不受到 ANR测量影响, UE执行 ANR测量是尽可能地最大努力方式地去做( best effort )。
步驟 205, 假设 UE选定了某个邻区列表内的目标小区并且重选进入, 而 UE在其内部的 ANR表中已经有了有效的 logging内容, 就在其发送给 目标小区所在的目标 RNC的某 RRC上行消息中(截至目前协议规范状态, 可以是 RRC Connection Setup Complete , Cell Update , URA Update , Measurement Report等消息),指示其 ANR测量结果已经拥有并且可以进行 上报。
步驟 206, 可选地, UE经过一定的 RRC信令交互之后, 进入到了某个 合适做 ANR测量结果上报的状态, 并且做好上报准备。 截至目前协议规范 状态, 上报的状态可以是 Cdl_DCH状态, Cdl_FACH状态。
步驟 207, 目标小区所在的目标 RNC通过某种 RRC下行消息, 要求 UE进行 ANR测量结果上 4艮。该过程被称为 ANR Logging Results Retrieval 截至目前协议规范状态, retrieval可以通过 UE Information Request消息实 现。
步驟 208, 根据目标 RNC的请求, UE通过某种 RRC上行消息上 4艮其 之前保存在 ANR表中的 ANR测量结果。 截至目前协议规范状态, retrieval 可以通过 UE Information Response消息实现。
步驟 209, 目标 RNC根据获得的 ANR测量结果, 维护其相关的邻区 关系列表 ( NRT, Neighbor Relation Table )。
上述 UTRA系统的 Log ANR方案是基于 UE最大努力方式而进行的, 为了不影响 UE原来的邻区列表内的常规小区重选行为,且 UE不会为 ANR 专门开启控制面信令, 去进行 ANR测量结果的上报。 这种机制对于减小对 用户服务体验的影响是有利的, 但是有时会影响到 ANR的性能。 比如, 当 网络在某小区下发给 UE ANR测量控制参数之后, UE并没有短时间内进入 可以执行 ANR测量的有效状态, 但 UE却切换到了新的小区环境, 使得之 前存储的那些 ANR测量控制参数并不是对新小区环境优化设置的。 还有, 当 UE本身不移动时, 一般 UE不发生常规小区重选行为, 即 UE长时间驻 留在原来的服务小区, 那么相应的 ANR测量很难捕捉到未知的相邻小区。 另外, 处于 Idle态或者 URA_PCH态的 UE移动范围较广, 若发生了多个 常规小区重选, 伴随此发生的 ANR测量也捕捉到了多个未知的相邻小区。 但是由于 UE—直没有上行的自然信令, 所以 UE不能上报其已经存储的 ANR测量结果的指示, 故网络无法获取 ( Retrieve )该 UE发现的未知邻区 关系。 上述几个例子说明, 现有的 ANR机制常常不能使网络给出优化的 ANR控制参数设置, 不能使网络在尽可能短的时间内, 获取到 UE发现的 最新未知邻区关系, 故而不能及时地对网络邻区关系进行调整优化, 不能 及时地提高网络的关键性能参数( KPI, Key Performance Indicators )。
为了提高网络做 ANR测量的时延方面的性能, 网络侧应该在 ANR测 量控制参数下发过程和 ANR测量结果上报过程中, 尽可能地缩短 ANR测 量时延, 同时尽量减小对用户服务体验的影响。 发明内容
有鉴于此, 本发明的主要目的在于提供一种自动邻区关系测量方法及 系统,在 UE处于可快速执行 ANR测量状态下时才向 UE发送 ANR测量配 置参数,这样, UE进行为小区重选而准备的邻区列表内相邻小区的测量时, 即可利用 自身所处状态拥有的较长非连接接收 ( DRX , Discontinuous Reception ) 空闲时段执行对未知相邻小区的 ANR测量, 并实现及时上报。

图 3为本发明应用实例 1的自动邻区关系测量方法的流程图; 图 4为本发明应用实例 2的自动邻区关系测量方法的流程图。 具体实施方式
本发明的基本思想为:网络侧仅在 UE处于可执行 ANR测量状态下时, 才向 UE发送 ANR测量配置参数; 而接收到 ANR测量配置参数的 UE, 则 利用自身所处的小区寻呼信道(Cell_PCH, Cell Paging Channel )状态, 或 小区前向接入信道( Cdl_FACH, Cell Forward Access Channel )状态 ( UE 具有增强 DRX周期,即增强 DRX周期的最大周期大于 320ms ,如为 640ms、 1280ms、 2560ms或 5120ms等) 的 DRX空闲时段执行对未知相邻小区的 ANR测量, UE发现新的未知相邻小区时, 利用其可以自然上发数据的机 会, 尽快地将 ANR测量结果上报给网络, 而不需要网络通过专门的消息进 行 retrieve
本发明中, 仅在 UE处于能够无缝转移的 Cdl_PCH状态下, 或具有增 强 DRX周期能力的 UE处于了 Cdl_FACH状态, 网络侧才向 UE下发包含 有 ANR 测量控制配置参数的 RRC 下行消息 (DL Message with ANR Configurations , ^列^口 i己录则量己置 ( Logged Measurement Configuration )消 息,或者测量控制( Measurement Control )消息 ) ,使该 UE利用较长的 DRX 空闲时段执行对未知相邻小区的 ANR测量, 并实现所检测到的未知相邻小 区信息的快速上报, 网络侧可以根据执行相邻小区信息进行当前服务小区 邻区列表的维护, 从而避免了因测量结果延时上报所导致的相邻小区信息 不准确的问题。 其中, 无缝转移的 Cell_PCH状态是指 UE不需要通过小区 更新流程, 就能直接转移到 Cdl_FACH状态, 并能进行上行数据传输; 具 有增强 DRX周期能力的 UE处于 Cell_FACH状态是指, 在 RellO之前的 CelLFACH状态能支持的 DRX最大周期为 320ms, 此 DRX周期长度不能 胜任本发明技术方案涉及的 ANR测量任务, 故被排除在 Log ANR方案可 行状态之外; 但如果 RellO之后对 Cell_FACH状态下 UE能支持的 DRX最 大周期进行延长, 比如延长到 640ms、 1280ms、 2560ms, 甚至逼近 RellO 中 Cdl_PCH状态能支持的 DRX最大周期长度 5120ms,那么拥有增强 DRX 周期长度 UE在处于 Cdl_FACH状态时也能进行有效的 ANR测量。本发明 的技术方案, 主要针对具有上述无缝转移的 Cell_PCH状态下的 UE, 或具 有增强 DRX周期的且处于 Cdl_FACH状态下的 UE。
以下对本发明的技术方案作进一步详细描述。
RNC对处于无缝转移的 Cell_PCH状态或者具有增强 DRX周期的且处 于 Cdl_FACH状态下的 UE, 直接下发包含有 ANR测量控制配置参数的 RRC下行消息 ( DL Message with ANR Configurations, 例如记录测量配置 ( Logged Measurement Configuration ) 消息, 或者测量控制 ( Measurement Control ) 消息)。 这些 ANRF配置参数和现有的 Log ANR方案的类似, 包 括有: ANR测量限时参数( ANR logging duration timer ), ANR测量范围限 制参数 ( ANR logging detection range ), 以及, Intra-frequency ANR logging , Inter-frequency ANR logging, Inter-RAT LTE ANR logging, Inter-RAT GSM ANR logging这四种基本 ANR测量类型相关的小区信号评估的参数( ANR logging absolute threshold, ANR logging relative threshold )。 UE保存这些 ANRF的配置参数之后, 立即执行 ANR测量。
UE一边进行为小区重选而准备的邻区列表内相邻小区的测量, 一边利 用自身所处状态拥有的较长 DRX OFF 空闲时段执行对未知相邻小区的 ANR测量。 当 UE发现某未知相邻小区满足 log条件时, UE将此未知相邻 小区记录下来。 UE通过合适的上行消息,比如 Measurement Report消息立即上报 ANR Log结果。 RNC基于 UE上报的 ANR Log结果, 立即维护当前服务小区 的邻区关系列表。
以下通过具体应用实例, 进一步阐明本发明技术方案的实质。
应用实例 1
图 3为本发明应用实例 1 的自动邻区关系测量方法的流程图, 如图 3 所示, 本示例的应用场景是某具备有无缝转移的 Cell_PCH状态能力的 UE 在某源小区 Source cell处于 Cell_PCH状态, 因此可以在 Cdl_PCH状态直 接接收专用控制信道(DCCH, Dedicated Control CHannel ) /高速下行链路 共享信道( HS-DSCH, High Speed Downlink Shared Control Channel )上传 输的包含 ANR测量控制参数的消息。 本示例的自动邻区关系测量方法包 括以下步驟:
步驟 301 , 源 RNC通过下发记录测量配置消息(Logged Measurement Configuration ), 将 ANR相关的控制配置参数发送给 UE。 该 UE当前处于 CelLPCH状态。
步驟 302, UE在 Cell_PCH状态下一边进行为小区重选而准备的邻区 列表内相邻小区的测量, 一边进行 ANR相关的未知相邻小区的测量。 发现 并且记录了 1个同频未知相邻小区, 并将其记录( log )在本地 ANR Log表 中。 本领域技术人员应当理解, UE接收 ANR测量控制参数并进行相应的 测量是现有技术, 是容易实现的, 由于 UE进行 ANR测量也非技术难点, 这里不再赘述其实现细节。
步驟 303, UE无缝转移到 Cell_FACH状态,然后直接通过 Measurement Report消息向源服务小区上报 ANR Log结果。 RNC基于 UE上报的 ANR Log结果, 立即维护当前服务小区的邻区关系列表。 本发明中, 服务小区的 邻区关系维护主要包括为服务'』、区添加新的邻区, 删除邻区等一般维护方 式。
应用实例 2
图 4为本发明应用实例 2的自动邻区关系测量方法的流程图, 如图 4 所示, 本示例的应用场景是某具有增强 DRX周期能力的 UE, 在某源小区 Source cell处于 Cell_FACH状态, 因此可以在 Cell_FACH状态直接接收 DCCH/HS-DSCH上传输的包含 ANR测量控制参数的消息。 本示例的自动 邻区关系测量方法包括以下步驟:
步驟 401 , 源 RNC通过下发测量控制消息(Measurement Control ), 将 ANR相关的控制配置参数发送给 UE。
步驟 402, UE在 Cdl_FACH状态下一边进行为小区重选而准备的邻区 列表内相邻小区的测量, 一边进行 ANR相关的未知相邻小区的测量。 发现 并且记录了 1个频外未知相邻小区, 并将其 log在本地 ANR Log表中。
步驟 403 , UE在 Cell_FACH状态, 然后直接通过 Measurement Report 消息向源服务小区上报 ANR Log结果。 RNC基于 UE上报的 ANR Log结 果, 立即维护当前服务小区的邻区关系列表。
