背景技术
长期演进（Long Term Evolution, LTE ) 网络由演进的陆地无线接入网 (Evolved UTRAN, E-UTRAN)基站（ Evolved NodeB , eNB )和演进分组交换 中心 （Evolved Packet Core, EPC )组成， 网络扁平化。 其中 EUTRAN包含 和 EPC通过 S1接口连接的 eNB的集合， eNB之间能通过 X2连接。 SI、 X2 是逻辑接口。一个 EPC可以管理一个或多个 eNB ,—个 eNB也可以受控于多 个 EPC ,一个 eNB可以管理一个或多个小区。 EPC是由移动管理单元（ Mobility Management Entity, MME )和服务网关（ Serving Gateway, SGW ) 、 分组数 据网络网关（ Packet Data Network Gateway, PGW )组成。 通用移动通讯系统 ( Universal Mobile Telecommunications System, UMTS )是由陆地无线接入网 ( UMTS Terrestrial Radio Access Network, UTRAN )和核心网（ core network, CN )组成，其中 UTRAN是由无线网络控制器（ Radio Network Controller,RNC ) 和基站 NodeB组成的。
无线网络优化是移动通信网络建设中一个重要的环节， 尤其是网络建设 初期， 通过对频率分配、 站点参数调整等手段来进一步优化无线网络性能， 提高通信质量。 无线网络优化的基本流程大致分为五个阶段： 优化准备， 数 据釆集， 数据分析， 实施优化， 优化评估。 无线网络性能一般由无线覆盖、 接通率、 掉话率、 话音质量、 系统容量等指标反映。 因此， 对这些指标的真 实值测量和收集是无线网络优化的基础。 通常这些指标的测量和收集是通过 路测 DT ( Drive Test ) 的进行， 即通过路测仪或者路测终端由人工对网络进 行检测。 DT的测试方法一般如下， 首先需要选定测试的区域和路线， 这个路 线可以是根据网络性能的统计或者运营商的需求得出， 重点的区域可以是市 中心密集区、 市区主要干道、 居民区、 高速公路、 铁路等。 测试车装备有测 试手机或路测仪器， 其中要带有 GPS功能和测试日志的记录功能。 测试车按 照测试的路线行驶， 路测终端或路测仪器发起各种业务， 对需要的测试指标 进行测试， 如： 发射功率、 无线信号质量、 切换成功率、 掉话率等， 并记录 测试的结果。 无线网络的规划和优化可以基于 DT测试的结果分析而进行优 化。 DT可以很好的对移动网络进行测试和评估，但是其存在浪费大量的人力、 物力和时间的缺点。 那么利用网络中的路测终端进行路测， 是一种比较好的 方法， 可以大范围的根据需要进行路测， 且不用浪费大量的人力、 物力。 一 种在无线移动通信系统中的利用路测终端进行路测的方法是， 无线接入网络 ( Radio Access Network, RAN )侧根据网管的需求通过控制面（ control plane , CP )给路测终端 （User Equipment, UE ) 下发路测的测量配置和上报信息， 路测终端进行路测后， 满足了路测结果的上报条件后， 通过控制面信令把路 测结果上报给 RAN, 然后 RAN把收集到的路测结果信息可以自己处理或发 给网管， 这样就实现了最小化路测 （Minimizing Drive Test, MDT ) 。 其中， 路测的测量包含空闲 IDLE态的测量和连接 CON 态的测量。 UE在测量到具 体的测量结果后， 可以将测量结果存储下来， 等到满足了上报条件后再将测 量结果上报。 这里的上报条件可以是： 按照绝对时间上报、 周期性上报、 基 于内存的使用情况、 基于位置的上报、 离开用户的投诉区， 还可以是各种条 件的联合。 按照是否测量后立即上报可以将测量分为立即上报和存储后上报 两种。对于存储后上报的方式， 当路测终端接收到网络侧下发的存储配置后， 这个配置会有一个有效时间， 在配置的有效时间内， 路测终端可以进行路测 测量， 当配置的有效时间超时时， 路测终端的测量记录停止， 当测量记录停 止时，如果路测终端一直保留未上报的测量结果会占用很多路测终端的内存， 进而可能导致路测终端运行緩慢， 因此需要对路测的测量记录进行有效的控 制。 发明内容

本发明的较佳实施方式
本发明路测测量记录控制方法、 路测系统及路测终端的主要思想是， 网 络侧向路测终端下发或路测终端自行设置测量记录有效时间， 当所述测量记 录有效时间超时或在测量记录有效时间内上>¾所述测量结果后， 所述路测终 端删除所述测量结果， 从而在路测终端长时间未触发上报测量结果时， 控制 路测终端对路测测量结果保留的有效时间长度， 使路测终端对于测量结果的 上 >¾和对存储空间的管理的更加有效， 节省内存空间。
如图 1所示， 本发明路测测量记录控制方法包括：
步骤 101： 网络侧向路测终端下发或路测终端自行设置测量记录有效时 间；
所述的测量记录有效时间表示当测量配置有效时间超时时， 路测终端停 止测量记录， 在这个有效时间内路测终端会保留还没有上报的测量结果。
步骤 102: 所述路测终端记录并保留路测得到的测量结果；
步骤 103 : 当所述测量记录有效时间超时或在测量记录有效时间内上才艮 所述测量结果后， 所述路测终端删除所述测量结果。
