本发明涉及移动通信领域的信令测量处理技术， 尤其涉及一种减少长 期演进（LTE， Long Term Evolution ) 网络中测量信令的方法、 设备、 系统 及存储介质。 背景技术
在 LTE网络中， 演进型基站（eNB， evolved Node B )的一种常见的移 动性管理策略是参照服务小区和服务小区的邻区信号差异进行用户设备 ( UE, User Equipment )的切换判决， 这里， 所谓服务小区是指 UE当前接 入的小区。
通常， 在 LTE 小区边缘存在与其它 LTE 小区信号重叠的覆盖区， 当 UE从服务小区中心向服务小区边缘移动时， 服务小区的信号会逐渐变小， 服务小区的邻区信号会逐渐变大； 当服务小区和邻区信号满足设定的阈值 后， eNB可以将 UE切换到邻区中， 由原服务小区的邻区作为 UE的新服务 小区， 为该 UE提供服务。
一般， eNB 在进行服务小区切换判决前， 需要通过连接态的测量机制 获取 UE服务小区及其邻区的信号情况， eNB可以控制处理连接态 UE的测 量行为， 如增加、 删除、 或修改 UE的测量配置等。 具体的， eNB通过 Uu 接口的无线资源控制协议连接重配置消息 RRC Connection Reconfiguration 配置 UE执行服务小区或邻区的测量及其测量上 行为； UE根据 eNB的测 量配置执行服务小区或邻区测量， 满足测量配置的触发条件后， UE通过 Uu接口的测量报告消息 Measurement Report将测量结果上报给 eNB; eNB 根据 UE的测量上报结果进行策略决策，如：将 UE切换到其它小区；其中， Uu接口为 UE和 E-UTRAN之间的空中接口。
在 LTE 网络中， 为了表征服务小区和邻区的信号相对变化情况， eNB 可以为 UE 配置与之匹配的测量事件， 如 A3 测量事件：
Mn + Ofn + Ocn - Hys > Ms + Ofs + Ocs + Off , 其中， Μη为邻区信号的测量结果， Ofn为邻 区频点的频率偏移， Ocn为邻区个体偏移， Hys为迟滞参数， Ms为服务小 区信号测量结果， Ofs为服务小区频率偏移， Ocs为个体偏移， Off为事件 门限。 UE检测服务小区和邻区的测量结果， 用于评估是否满足上述事件条 件， 若满足则触发测量上报。 在进行测量事件评估时， UE将测量载频对象 邻区列表指示的小区 （即列表小区）和测量载频对象邻区列表没有指示的 小区 （即检测小区）用于事件评估， 无论是列表小区还是检测小区， 只要 满足测量事件触发条件， UE则通过 Measurement Report消息将测量结果发 送给 eNB; Measurement Report消息中包含服务小区的信号测量结果及邻区 的物理小区标识和信号测量结果。
对于切换目的的测量事件， eNB 仅仅依据测量报告的邻区的物理小区 标识是无法准确定位切换目标小区的， 需要 eNB将邻区的物理小区标识映 射为含移动国家码、 移动网络码、 小区标识的演进型小区全球标识（ECGI， Evolved Cell Global Identifier )信息来确定切换目标小区。 若 UE将所有检 测小区通过测量^艮告消息发送给 eNB， eNB在确定切换目标小区时， 将邻 区的物理小区标识映射为 ECGI过程中可能存在失败， 比如： 没有确定该物 理小区的映射规则， 也就是没有配置邻区关系， 将导致该测量处理失败。
现有技术中， 一方面， LTE 系统配置映射规则， 即： 小区间的邻区关 系， 是一项复杂、 费力、 且易出错的工作， 经常会出现邻区漏配情况； 另 一方面， 实际商用场景网络环境复杂， 小区信号覆盖存在调整的可能性， 加剧了邻区关系配置的难度。 因此， 切换测量处理失败是网络中一种常见 的现象， 会造成网络中大量无效空口测量信令交互。 目前， 使用自动邻区关系配置技术可解决上述问题， 但是， 需要 UE 和 eNB均支持自动邻区关系相关技术， 而目前邻区关系配置技术在标准中 并没有做强制要求， 是可选功能； 因此， 不能保证所有 UE和 eNB均支持 自动邻区关系相关技术； 即使 UE支持自动邻区关系相关技术， 鉴于 UE执 行自动邻区关系技术的相关测量时， 不可避免会影响终端的其它业务功能， 因此， 网络运营商会根据自身需要在特定时期和特定区域开启自动邻区关 系功能。 发明内容
