Description

异频测量参数的配置方法、 装置及基站 技术领域 本发明涉及通信领域， 具体而言， 涉及一种异频测量参数的配置方法、 装置及基 站。 背景技术 为了满足日益增长的大带宽高速移动接入的需求， 第三代伙伴组织计划 （Third Generation Partnership Projects, 简称 3GPP) 推出高级长期演进 (Long-Term Evolution advance,简称 LTE- Advanced)标准。 LTE- Advanced对于长期演进（Long-Term Evolution, 简称 LTE) 的演进保留了 LTE的核心， 并在此基础上采用了一系列技术对频域、 空域 进行扩充， 以达到提高频谱利用率、 增加系统容量等目的。 通常， 无线通信系统为了能够大范围地为用户提供无线通信， 需要部署覆盖范围 大的基站。 这种基站通常称为宏基站 （Macro), 其覆盖的小区通常称为宏区 （Macro Cell). 同时， 考虑到用户的不同需求和不同使用环境， 需要在某些环境或者场景下为 用户提供更高质量的无线通信服务， 一些覆盖范围小、 发射功率较低的基站因而被采 用。 这些小型基站包括微基站 （Pico) 和家庭基站 （He B)。 由于宏基站和微基站、 家庭基站覆盖范围差别巨大， 在宏区的覆盖范围内可能部 署有大量的微基站和家庭基站。 微基站可进行覆盖增强以及分担宏站的负荷， 而家庭 基站可用于改善室内的通信服务质量。 在 Macro, Pico以及 HeNB同时部署的异构网 络场景下， 会出现同覆盖的各节点间的干扰问题。 如图 1中的场景 （a) 所示， Macro发射功率较 Pico大很多， 导致 Macro对 Pico 边界用户下行接收的干扰， 以及 Macro边缘大功率终端对附近 Pico的干扰。 而在图 1 中的场景（b)下， 如果 HeNB属于封闭用户组（Closed Subscriber Group, 简称 CSG)， 则 HeNB会对附近 Macro 用户造成干扰。为了解决异构网络上述两种场景的干扰问题， 3GPP在 R10启动了 elCIC (enhanced Inter-cell Interference Coordination) 的研究， 旨 在采用时分的方式解决同覆盖的各节点间的干扰问题。 目前现有标准基于 elCIC的研究引入了几乎空白子帧 （Almost Blank Subframe, 简称为 ABS) 的概念， 在 ABS上， 基站仅发送参考信号， 不再发送控制信道以及数 据信道。 如图 1中场景 （a) 所示， Macro是干扰小区， Pico是被干扰小区， Macro需 要将若干子帧设置成 ABS， 在这些子帧上不再发送控制信息及数据， 相应的， Pico可 在对应的 ABS上， 调度受干扰的 Pico用户进行下行接收， 从而保证受干扰的 Pico用 户可以正常工作。 为了保证受干扰的用户能够正确的切换到合适的小区，基站要根据 ABS的设置为 受干扰的用户配置相应的测量约束子集。 例如， 对于受干扰的 Pico用户， 在测量当前 服务 Pico小区时， 应尽可能选择在干扰 Macro小区所配置的 ABS上进行测量。 在目 前标准中规定了基站可以为受干扰的用户配置同频服务小区以及邻区的测量子帧模 式。 假设网络部署采用多个频点， 如图 1所示， 则用户不仅要测量同频的服务小区以 及邻区，还需要测量异频的相邻小区。如果异频的相邻小区实施了 elCIC, 即采用 ABS 进行时分的干扰协调， 则用户在测量异频的相邻小区时也需要配置相应的测量子帧模 式。 但是与同频测量相比， 用户对异频相邻小区的测量又有其特殊性， 如图 2所示， 图 2中的 Cl， C2， C3， Cn指不同的频点， 在异频测量时， 用户需要在周期性出现的 测量间隔时间内选择不同于服务小区的频点进行测量， 在此期间用户的服务小区不再 调度该用户。 测量间隔通常固定为 6ms， 有可能出现在测量间隔与用户的异频测量子 帧模式不重叠的现象， 导致用户的测量结果不准确。 发明内容 本发明提供了一种异频测量参数的配置方法、 装置及基站， 以至少解决相关技术 中由于出现测量间隔与用户的异频测量子帧模式不重叠的现象， 导致用户的测量结果 不准确的问题。 根据本发明的一个方面， 提供了一种异频测量参数的配置方法。 根据本发明的异频测量参数的配置方法包括： 基站获取相邻基站小区的干扰协调 信息;基站根据干扰协调信息为其所服务的用户设备配置或重配置异频测量间隔偏移 以及测量子帧模式。 上述干扰协调信息包括： 相邻基站小区的频点信息、 干扰类型以及几乎空白子帧 模式信息。 上述几乎空白子帧模式信息包括： 如果相邻基站小区是干扰小区， 则几乎空白子 帧模式信息为该相邻基站小区设置的几乎空白子帧模式信息； 如果相邻基站小区是被 干扰小区， 则几乎空白子帧模式信息为干扰相邻基站小区的相邻小区所配置的几乎空 白子帧模式信息。 上述干扰协调信息还包括： 相邻基站小区标识信息。 上述干扰协调信息还包括： 相邻基站提供的测量子集信息。 上述基站获取相邻基站小区的干扰协调信息包括： 基站从网管系统获取的干扰协 调信息。 上述基站获取相邻基站小区的干扰协调信息包括： 基站通过与相邻基站小区所属 的相邻基站的 X2连接建立过程获取干扰协调信息。 上述基站获取相邻基站小区的干扰协调信息包括： 基站接收来自于移动管理实体 的移动管理实体配置传送消息， 其中， 该移动管理实体配置传送消息携带有： 干扰协 调信息。 上述基站获取相邻基站小区的干扰协调信息包括： 基站向移动管理实体发送第一 基站配置传送消息， 其中， 该第一基站配置传送消息携带有基站的干扰协调信息； 移 动管理实体向相邻基站小区所属的相邻基站发送第一移动管理实体配置传送消息， 其 中， 该第一移动管理实体配置传送消息携带有基站的干扰协调信息以及请求相邻基站 发送干扰协调信息的指示信息；相邻基站向移动管理实体发送第二基站配置传送消息， 其中， 该第二基站配置传送消息携带有相邻基站的干扰协调信息； 移动管理实体向基 站发送第二移动管理实体配置传送消息， 其中， 该第二移动管理实体配置传送消息携 带有相邻基站的干扰协调信息； 基站接收第二移动管理实体配置传送消息， 并更新保 存相邻基站的干扰协调信息。 上述基站获取相邻基站小区的干扰协调信息包括： 当相邻基站小区的干扰协调信 息发生变化时， 相邻基站小区所属的相邻基站通过 X2接口发送基站更新配置消息， 其中， 基站更新配置消息携带有变化后的干扰协调信息。 上述基站根据干扰协调信息为其所服务的用户设备配置或重配置异频测量间隔偏 移以及测量子帧模式包括： 基站根据干扰协调信息为用户设备选择异频测量间隔偏移 并确定测量子帧模式， 其中， 从选择的异频测量间隔偏移开始的测量间隔与几乎空白 子帧模式或测量子集有重叠； 基站为用户设备配置或重配置选择的异频测量间隔偏移 以及确定的测量子帧模式。 上述基站为用户设备配置或重配置选择的异频测量间隔偏移以及确定的测量子帧 模式包括： 基站根据用户设备以及相邻基站小区的位置， 为用户设备配置或重配置选 择的异频测量间隔偏移以及确定的测量子帧模式。 在上述基站为用户设备配置或重配置选择的异频测量间隔偏移以及确定的测量子 帧模式之后， 还包括： 当相邻基站小区的频点信息及几乎空白子帧模式信息发生变化 时，基站判断是否需要为用户设备更新异频测量间隔偏移及测量子帧模式； 如果需要， 则为用户设备选择新的异频测量间隔偏移并确定新的测量子帧模式， 其中， 从新的异 频测量间隔偏移开始的测量间隔与更新后的几乎空白子帧模式或测量子集有重叠； 基 站为用户设备配置或重配置新的异频测量间隔偏移以及新的测量子帧模式。 上述基站通过以下消息为用户设备配置或重配置异频测量间隔偏移以及测量子帧 模式： 连接重配置消息。 根据本发明的另一方面， 提供了一种异频测量参数的配置装置。 根据本发明的异频测量参数的配置装置包括： 获取模块， 设置为获取相邻基站小 区的干扰协调信息； 配置模块， 设置为根据干扰协调信息为该配置装置所服务的用户 设备配置或重配置异频测量间隔偏移以及测量子帧模式。 上述获取模块包括： 第一获取单元， 设置为从网管系统获取干扰协调信息。 上述获取模块包括： 第二获取单元， 设置为通过与相邻基站小区所属的相邻基站 的 X2连接建立过程获取干扰协调信息。 上述获取模块包括： 第一接收单元， 设置为接收来自于移动管理实体的移动管理 实体配置传送消息， 其中， 该移动管理实体配置传送消息携带有： 干扰协调信息。 上述获取模块包括： 发送单元， 设置为经由移动管理实体发送基站的干扰协调信 息； 第二接收单元， 设置为经由移动管理实体接收相邻基站小区所属的相邻基站的干 扰协调信息。 上述获取模块包括： 第三接收单元， 设置为在相邻基站小区的干扰协调信息发生 变化时， 通过 X2接口接收来自于相邻基站小区所属的相邻基站的基站更新配置消息， 其中， 基站更新配置消息携带有变化后的干扰协调信息。 上述配置模块包括： 决策单元， 设置为根据干扰协调信息为用户设备选择异频测 量间隔偏移并确定测量子帧模式， 其中， 从选择的异频测量间隔偏移开始的测量间隔 与几乎空白子帧模式或测量子集有重叠； 处理单元， 设置为为用户设备配置或重配置 选择的异频测量间隔偏移以及确定的测量子帧模式。 通过本发明， 基站获取相邻基站小区的干扰协调信息； 所述基站根据所述干扰协 调信息为其所服务的用户设备配置或重配置异频测量间隔偏移以及测量子帧模式， 使 得从该测量间隔偏移开始的测量间隔与 ABS尽可能有重叠，解决了相关技术中由于出 现测量间隔与用户的异频测量子帧模式不重叠的现象， 导致用户的测量结果不准确的 问题， 进而可以保证用户设备在干扰协调场景下异频测量结果的准确性， 使得受干扰 的用户能够正确的切换到合适的小区。 附图说明 此处所说明的附图用来提供对本发明的进一步理解， 构成本申请的一部分， 本发 明的示意性实施例及其说明用于解释本发明， 并不构成对本发明的不当限定。 在附图 中： 图 1是根据相关技术的干扰协调场景的示意图； 图 2是根据相关技术的异频测量间隔的示意图； 图 3是根据本发明实施例的异频测量参数的配置方法的流程图;

( 1 ) 如果相邻基站小区是干扰小区， 则相邻基站小区的 ABS模式信息指相邻基 站小区设置的 ABS模式信息； (2) 如果相邻基站小区是被干扰小区， 则相邻基站小区的 ABS模式信息是指干 扰相邻基站小区的相邻小区所配置的 ABS模式信息。 在优选实施过程中， 针对不同的应用场景， 上述干扰协调信息还可以包括： 相邻 基站小区标识信息。 在优选实施过程中， 针对不同的应用场景， 上述干扰协调信息还可以包括： 相邻 基站提供的测量子集信息。 优选地， 针对不同的应用场景， 上述步骤 S302可以包括多种实施方式。 以下结合 示例进行描述。 ( 1 ) 基站从网管系统获取的干扰协调信息。 例如，基站从网管获取相邻基站小区频点，小区标识，干扰类型及 ABS模式信息。

(3 ) 基站接收来自于移动管理实体 （MME) 的 MME配置传送消息， 其中， 该 MME配置传送消息携带有： 获取的干扰协调信息。 例如，基站根据收到包含相邻基站小区频点以及 ABS模式信息的 MME配置传送 消息， 获取相邻基站的频点， 小区标识， 干扰类型， ABS模式信息， 可选的， 可交互 相邻基站测量子集信息。
(4)基站向 MME发送第一基站配置传送消息， 其中， 该第一基站配置传送消息 携带有基站的干扰协调信息； MME 向相邻基站小区所属的相邻基站发送第一 MME 配置传送消息， 其中， 该第一 MME配置传送消息携带有基站的干扰协调信息以及请 求相邻基站发送干扰协调信息的指示信息； 目标相邻基站向 MME发送第二基站配置 传送消息， 其中， 该第二基站配置传送消息携带有相邻基站的干扰协调信息； MME 向基站发送第二 MME配置传送消息， 其中， 该第二 MME配置传送消息携带有相邻 基站的干扰协调信息； 基站接收第二 MME配置传送消息， 并更新保存相邻基站的干 扰协调信息。 例如， 基站向移动管理实体发送基站配置传送消息， 该消息携带基站小区频点， 小区标识， 干扰类型， ABS模式信息,可选的测量子集等干扰协调信息， 可选的， 该消 息可包含请求目标基站发送干扰协调信息的指示； 移动管理实体将包含干扰协调信息 的自组织信息通过移动管理实体配置传送消息发送给基站配置传送消息所指示的目标 相邻基站； 目标相邻基站收到该消息后， 如果该消息包含请求目标基站发送干扰协调 信息的指示， 则目标相邻基站向移动管理实体发送基站配置传送消息， 该消息携带目 标相邻基站小区频点， 小区标识， 干扰类型， ABS模式信息,可选的测量子集等自组织 信息； 移动管理实体将包含干扰协调信息的自组织信息通过移动管理实体配置传送消 息发送给基站配置传送消息所指示的基站；基站根据收到移动管理实体配置传送消息， 更新保存的相邻基站的小区标识， 干扰类型， ABS模式信息,可选的测量子集等干扰协 调信息。
( 5 )当相邻基站小区的干扰协调信息发生变化时，相邻基站小区所属的相邻基站 通过 X2接口发送基站更新配置消息， 其中， 基站更新配置消息携带有变化后的干扰 协调信息。 同样的， 当基站的干扰协调信息发生变化时， 也可以通过 X2接口发送包含新的 干扰协调信息的基站配置更新消息给相邻基站。 优选地， 上述步骤 S306可以进一步包括以下处理：

在基站为用户设备配置或重配置选择的异频测量间隔偏移以及确定的测 量子帧模式之后， 当相邻基站小区的频点信息及 ABS模式信息发生变化时， 基站判断 是否需要为用户设备更新异频测量间隔偏移及测量子帧模式； 如果需要， 则为用户设 备选择新的异频测量间隔偏移并确定新的测量子帧模式， 其中， 从新的异频测量间隔 偏移开始的测量间隔与更新后的 ABS模式或测量子集重叠尽可能最大；基站为用户设

在优选实施过程中， 如果在基站收到 MME configuration transfer消息之前， 基站 已经为接入的用户设备配置了异频测量间隔偏移及测量子帧模式， 则基站根据更新后 的邻区的频点及 ABS模式信息， 为用户设备重新选择测量间隔与 ABS模式重叠的异 频测量间隔偏移以及测量子帧模式， 如果较之前有变化， 则基站通过连接重配置消息 发给用户设备。 步骤 S606:

带目标相邻基站小区的工作频点， 小区标识， 干扰类型， ABS模式， 测量子集等信息。 步骤 S708: 移动管理实体将包含工作频点， 小区标识， 干扰类型， ABS模式， 测 量子集等信息的自组织信息通过移动管理实体配置传送消息发送给基站配置传送消息 所指示的基站， 基站根据收到移动管理实体配置传送消息， 更新保存的相邻基站的干 扰协调信息。 步骤 S710: 当后续有用户设备接入到该基站后， 基站根据相邻小区的干扰协调信 息， 为用户设备选择测量间隔与 ABS模式重叠的异频测量间隔偏移， 并给出测量子帧 模式。 在基站为用户选择异频测量参数过程中， 基站还可进一步根据用户设备以及相邻 小区的位置， 判断 UE到异频环境是否为受干扰的用户设备， 然后更精准的为不同的 用户设备配置不同的异频测量间隔偏移及测量子帧模式。 在优选实施过程中， 如果在基站接收到 MME
