在上述组网方式下，如图1所示，当UE快速移动时，该UE在短时间内可能会经过多个微小区，由于微小区建立的目的是为了分担宏小区中的业务量，UE通常会选择微小区作为服务小区。当UE从宏小区分别经过如图1所示的微小区A至微小区B至微小区C时，UE可能驻留的服务小区依次为微小区A、微小区B及微小区C，当UE在上述微小区间切换时，UE与微小区之间的通信可能会中断，从而UE的掉线率会提升。
为解决上述问题，在传统方式中，当有UE切换进微小区时，对应的微基站基于UE上报的历史驻留小区信息确定该UE是否为高速UE，若微基站确定该UE为高速UE，则将该高速UE从微小区切换至宏小区，或者，该微基站调节切换至邻近微基站的触发条件，例如增加该高速UE切换至邻近微基站的难度，从而降低该高速UE切换进微小区的频率，保证高速UE的通信质量。
然而，上述方式中，微基站需要基于每个切换进对应微小区内的UE进行判断，判断该UE是否为高速UE，并需要对每个判断出的高速UE采用上述方式以降低该高速UE切换微小区的频率，即微基站仅能够在高速UE进入微小区后对其采取控制措施，而无法从根本杜绝高速UE进入微小区的可能，如此，增 加了微基站的工作量，降低了微小区的通信性能。

具体实施方式
为了使本技术领域的人员更好地理解本发明方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚地描述，显然，所描述的实施例仅仅是本发明一部分的实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本发明保护的范围。

下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行描述。
本发明实施例公开了一种小区切换方法及相关装置，能够从根本上杜绝高速用户设备切换进微小区的可能性，降低高速用户设备的小区切换频率，进而降低用户设备的通话掉线率。为了更好的理解本发明实施例，下面先对本发明实施例的应用场景进行描述，其中，本发明实施例中的应用场景也可理解为本发明方法及装置实施例所应用的通信系统。
请参阅图2，图2是本发明实施例公开的宏基站与微基站混合组网的场景示意图。在图2所示场景下，宏小区内存在一个微小区A，用户设备A与用 户设备B当前的服务小区为宏小区。在传统的实施方式中，若用户设备A或用户设备B从宏小区高速经过微小区A时，微基站A无法通过用户设备A或用户设备B所携带了历史驻留小区信息准确判断出用户设备A或用户设备B是否为高速用户设备。从而，微基站A无法及时对用户设备A或用户设备B做出相应切换处理，导致用户设备A或用户设备B仍存在通信掉线的问题，并且微基站A无法通过上述传统实施方式从根本上杜绝高速用户设备切换进微小区A。
当然，本发明实施例适用的应用场景还可为图1所示的场景示意图。即宏小区内存在多个微小区，在图1所示的应用场景中，宏小区内存在微小区A、微小区B及微小区C。在传统的实施方式中，若用户设备分别经过微小区A、微小区B及微小区C时，微基站A或微基站B通过用户设备上传的历史驻留小区信息可能无法准确判断出用户设备为高速用户设备，则无法及时对该用户设备进行处理，而当微基站C能够通过历史驻留小区信息确定该用户设备为高速用户设备时，该用户设备已经经过了多个微小区，导致无法降低用户设备切换进小区的频率，进而无法有效降低该用户设备的通信掉线率，并且微基站A、微基站B或微基站C都不能从根本上杜绝宏小区中的高速用户设备切换进本小区。
综上所述，本发明实施例的应用场景为宏基站与至少一个微基站混合组网，宏小区覆盖上述至少一个微小区。
本发明实施例提供的技术方案可以应用于各种无线通信网络，例如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time division multiple access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single carrier FDMA，SC-FDMA)和其它网络等。术语“网络”和“系统”可以相互替换。CDMA网络可以实现例如通用无线陆地接入(universal terrestrial radio access，UTRA)，CDMA2000等无线技术。UTRA可以包括CDMA(WCDMA)和其他CDMA的变形。CDMA2000可以覆盖临时标准(Interim Standard，IS)2000(IS-2000)，IS-95和IS-856标准。TDMA网络可以实现例如全球移动通信系统(global system for mobile communication，GSM)等无线技术。OFDMA网络可以实现诸如演进通用无线陆地接入(evolved  UTRA，E-UTRA)、超级移动宽带(ultra mobile broadband，UMB)、IEEE 802.11(Wi-Fi)，IEEE 802.16(WiMAX)，IEEE 802.20，Flash OFDMA等无线技术。UTRA和E-UTRA是UMTS以及UMTS演进版本。3GPP在长期演进(long term evolution，LTE)和LTE高级(LTE Advanced，LTE-A)是使用E-UTRA的UMTS的新版本。UTRA、E-UTRA、UMTS、LTE、LTE-A和GSM在3GPP标准组织的文档中有记载描述。CDMA2000和UMB在3GPP2标准组织的文档中有记载描述。本发明实施例描述的技术也可以应用到上述所述的无线网络和无线技术中。
本发明实施例中，在应用场景中的微基站可为皮(pico)基站、毫微微(femto)基站或者家(home)基站等。在应用场景中的每个用户设备可以是静态的或移动的。用户设备可以称为终端(terminal)，移动台(mobile station)，用户单元(subscriber unit)，站台(station)等。UE可以为蜂窝电话(cellular phone)，个人数字助理(personal digital assistant，PDA)，无线调制解调器(modem)，无线通信设备，手持设备(handheld)，膝上型电脑(laptop computer)，无绳电话(cordless phone)，无线本地环路(wireless local loop，WLL)台等。
结合图1或图2所示应用场景，下面对本发明实施例中的方法实施例进行详细说明。
请参阅图3，图3是本发明实施例公开的一种小区切换方法的流程示意图。如图3所示，该方法可包括以下步骤。
步骤S301，用户设备A向宏基站发送测量报告。
在一个实施例中，用户设备A可基于宏基站发送的携带配置参数的测量控制信息，确定是否向宏基站发送测量报告。用户设备A在宏小区内能够接收到宏基站与微基站的信号质量，例如，在LTE系统或LTE-A系统中，用户设备A接收到的宏基站与微基站的信号质量可为参考信号接收质量(Reference Signal Receiving Quality，RSRQ)或者参考信号接收功率(Reference Signal Receiving Power，RSRP)。并且，宏基站发送的测量控制信息中所携带的配置参数包括针对上述信号质量的偏置量，即配置参数。用户设备A基于接收到的信号质量以及针对该信号质量的偏置量确定能够发送测量报告的触发条件。例如，在LTE系统或LTE-A系统中，用户设备A满足触发条件时，可向宏基站发送携带事件Ax的测量报告，具体的触发条件与时间Ax对应，x＝1,2,3,4 等(可参见3GPP TS 36.331 V10.1.0标准中的具体事件描述)。如用户设备A基于接收到的信号质量以及针对该信号质量的偏置量确定满足事件A3中描述的触发条件时，可向宏基站发送携带事件A3的测量报告。当用户设备A发送测量报告时，即表明用户设备A申请进行服务小区切换。本发明实施例中，用户设备A向宏基站发送测量报告，表明用户设备A向宏基站申请服务小区从宏小区切换至微小区。
步骤S302，所述宏基站接收所述用户设备A发送的测量报告，并基于所述测量报告控制所述用户设备A的服务小区从宏小区切换至微小区。
在一个实施例中，宏基站接收到用户设备A发送的测量报告后，则宏基站可向用户设备A发送控制命令，以控制用户设备A将其服务小区从宏小区切换至微小区。具体的，宏基站在接收到用户设备A发送的测量报告后，可向微基站发送切换请求消息，该切换请求消息中包含切换准备的相关信息。微基站基于接收到的切换请求消息进行切换准备，并在完成切换准备时通知宏基站释放资源，用户设备A与微基站进行同步，从而完成用户设备A的服务小区切换过程。
步骤S303，所述用户设备A在所述宏基站的控制下将服务小区从所述宏小区切换至所述微小区。
步骤S304，微基站获取所述用户设备A的信息。
在一个实施例中，微基站能够获取用户设备A的信息。具体的，微基站可接收用户设备A发送的信息。微基站通过获取用户设备A的信息，能够确定该用户设备A是否为高速用户设备。可选的，用户设备A的信息可携带在用户设备A向微基站发送的测试报告中，即用户设备A在请求切换服务小区时，微基站可获取用户设备A的信息。或者，微基站通过向用户设备A发送查询消息，以获取用户设备A的信息。或者，微基站与用户设备A约定获取时间，微基站在约定的获取时间获取用户设备A的信息。
步骤S305，所述微基站根据所述用户设备A的信息，确定所述用户设备为高速用户设备后，所述微基站向宏基站发送第一消息，所述第一消息用于请求所述宏基站更改所述宏基站所服务的宏小区中的高速用户设备发送测量报告的触发条件，所述微小区处于所述宏基站覆盖范围。
在一个实施例中，当微基站根据获取的用户设备A的信息，确定用户设 备A为高速用户设备后，微基站向宏基站发送第一消息，该第一消息用于请求宏基站更改宏小区内的用户设备能够发送测量报告的触发条件，进而增加宏小区中高速用户设备切换进该微小区的难度。需要说明的是，在这里，微基站与宏基站确定用户设备是否为高速用户设备的准则相同，即当用户设备的移动速度或平均移动速度达到微基站与宏基站共知的预设高速阈值，或者，用户设备的移动速度对应的等级标识为微基站与宏基站共知的高速等级时，则微基站或宏基站可确定该用户设备为高速用户设备。可选的，如图1所示的应用场景，当宏小区内存在多个微小区时，不同的微小区对于用户设备是否为高速用户设备的准则不同，即不同的微基站可与宏基站约定不同的预设高速阈值或高速等级。进而，当微基站向宏基站发送第一消息，以请求宏基站更改宏小区内的高速用户设备发送测量报告的触发条件时，这里所指的高速用户设备为该微基站与该宏基站根据共知的确定准则确定出的高速用户设备。当然，宏基站可基于不同的微基站发送的第一消息，确定与该微基站对应的高速用户设备。
可选的，上述第一消息中可携带微基站统计出的高速用户设备的数量。可选的，微基站确定用户设备A为高速用户设备后，即可向宏基站发送第一消息；或者，微基站在一段时间后(如统计出的高速用户设备的数量超过预设数量阈值时)，或基于与宏基站协商的发送周期向宏基站发送第一消息，在此，本发明实施例不做限定。
步骤S306，所述宏基站接收所述微基站发送的所述第一消息。
在一个实施例中，宏基站接收微基站发送的第一消息。其中，宏基站可在协商的时间点或协商的周期内接收微基站的第一消息，或者宏基站也可随时接收微基站发送的第一消息。
步骤S307，当所述宏基站确定出所述宏小区内的高速用户设备B后，所述宏基站更改所述高速用户设备B发送测量报告的触发条件。
在一个实施例中，当宏基站接收到微基站发送的第一消息后，可确定宏小区内的高速用户设备，本发明实施例中，以宏基站确定用户设备B为高速用户设备为例。其中，由于宏基站与所述微基站确定高速用户设备的准则相同，宏基站确定用户设备B为高速用户设备的方式可参见微基站确定高速用户设备的方式。需要注意的是，这里宏基站确定的高速用户设备B是针对上述微基站而言，若其他微基站，则由于确定准则的不同，有可能宏基站确定用户设 备B不是高速用户设备。举例说明，在如图1所示的应用场景中，用户设备B有可能针对微基站A为高速用户设备，针对微基站B不是高速用户设备。
当宏基站确定出高速用户设备B后，可更改该高速用户设备B发送测量报告的触发条件。使高速用户设备B在更改触发条件后，尽量避免向宏小区发送测量报告。进而增加了高速用户设备B切换小区的难度。从而从根本上杜绝了相对于微小区为高速用户设备切换进该微小区的可能。
步骤S308，所述高速用户设备B检测到所述微小区时，确定是否满足向所述宏基站发送测量报告的触发条件。
在一个实施例中，当高速用户设备B接收到微基站的信号质量，可通过宏基站更改的触发条件，确定当前接收到的微基站的信号质量是否能够满足上述触发条件，若能够满足，则可向宏基站发送测量报告，若不能够满足，则不能够向宏基站发送测量报告。具体的，若高速用户设备B不满足该触发条件，则高速用户设备B不会向宏基站发送测量报告，进而宏基站通过更改高速用户设备B的触发条件，避免了高速用户设备B切换进微小区；若高速用户设备B满足触发条件，则高速用户设备B向宏基站发送测量报告，则可循环执行步骤S301～步骤S308，使宏基站进一步增加宏小区内其他高速用户设备切换进微小区的难度。
可见，当微基站确定微小区内存在高速用户设备时，可向宏基站发送第一消息，宏基站在接收到该第一消息后，能够更改宏小区内高速用户设备发送测量报告的触发条件，进而增加高速用户设备切换进微小区的难度，从而通过上述方式能够从根本上杜绝高速用户设备切换进微小区的可能，降低了高速用户设备的小区切换频率，进而降低了高速用户设备的通信掉线率。
请参阅图4，图4是本发明实施例公开的另一种小区切换方法的流程示意图。如图4所示，该方法应用于微基站，且该方法重点描述微基站确定用户设备为高速用户设备的具体方式。该方法可包括以下步骤。
步骤S401，微基站接收用户设备发送的测量报告。
在一个实施例中，微基站可通过接收用户设备发送的测量报告，获取用户设备的信息。当微基站接收到用户设备发送的测量报告时，表明用户设备申请切换出该微基站对应的微小区。此时，微基站可对该用户设备是否为高速用户设备进行综合判断。从而微基站可确定是否有高速用户设备经过微小区。通常， 经过微小区的高速用户设备在微小区的驻留时间较短，其并不需要进行服务小区的切换，会导致通信掉线率的增加。因此，微基站需要向宏基站请求避免更多的高速用户设备切换进微小区中。
步骤S402，所述微基站确定所述用户设备为高速用户设备。
在一个实施例中，当微基站接收到用户设备发送的测量报告后，可进一步根据测量报告中携带用户设备的信息确定该用户设备是否为高速用户设备。其中，微基站确定用户设备是否为高速用户设备的具体方式可包括以下方式中的任意一种。
(1)、微基站接收到的测量报告中可包括用户设备的速度信息，所述速度信息为所述用户设备的移动速度数值或与所述移动速度对应的等级标识。
微基站可根据测量报告中的速度信息，判断用户设备是否为高速用户设备。
具体的，微基站可根据预先与用户设备协商的解析规则解析出测量报告中的用户设备的速度信息，该速度信息可为用户设备上报的移动速度数值或与移动速度对应的等级标识，该等级标识用于标识用户设备的移动速度为高速、中速或低速等。微基站可在检测到该用户设备切换进小区时，即可向用户设备发送控制信令，该控制信令用于控制用户设备在发送测量报告时携带速度信息；或者，携带用户设备的速度信息的测量报告已为微基站与用户设备所共知，即每一个微小区内的用户设备在发送测量报告时均需要携带该用户设备的速度信息。
用户设备可通过配置的传感器等装置监测该用户设备的移动速度，并可对监测的移动速度进行处理，如确定用户设备的平均移动速度，或者基于用户设备的移动速度确定速度等级标识等。用户设备可与微基站协商移动速度满足高速条件的阈值，即预设高速阈值。该预设高速阈值或速度等级标识可基于微小区的范围大小、用户设备的移动能力或移动条件等参数确定。用户设备可基于在微小区内的平均移动速度确定速度等级标识，如用户设备确定在微小区内的平均移动速度大于50KM/H时，确定等级标识为高速标识；用户设备确定在微小区内的平均移动速度介于50KM/H～30KM/H之间，确定等级标识为中速标识；用户设备确定在微小区内的平均移动速度小于30KM/H，确定等级标识为低速标识。
微基站接收到携带速度信息的测量报告后，若所携带的速度信息为移动速 度的数值，则可确定该移动速度数值是否高于预设高速阈值；若所携带的速度信息为等级标识，则微基站确定该等级标识是否用于标识用户设备的移动速度为高速。若微基站确定移动速度数值高于预设高速阈值或者等级标识用于标识用户设备的移动速度为高速，则微基站确定该用户设备为高速用户设备。
(2)、所述微基站获取用户设备在微小区的驻留时间；
所述微基站根据所述用户设备在所述微小区内的移动轨迹信息及所述驻留时间，确定所述用户设备在所述微小区内的平均速度；
若所述微基站确定所述平均速度达到所述预设高速阈值，则确定所述用户设备为高速用户设备。
具体的，当微基站接收到用户设备上报的测量报告后，微基站可进一步获取用户设备在微小区的驻留时间。其中，用户设备在微小区的驻留时间可从与用户设备交互的用户设备历史驻留信息中获取，如在LTE或LTE-A系统中，用户设备可向基站上报用户设备的历史驻留信息，其中，驻留时间可在历史驻留信息的驻留小区时间(Time UE stayed in Cell)字段中获取；或者，微基站记录用户设备切换进微小区的时间点，并记录微基站接收到用户设备上报的测量报告的时间点，根据上述两个时间点之差计算出用户设备在微小区的驻留时间；或者，用户设备上报的测量报告中可携带有用户设备在微小区的驻留时间信息，如用户设备从进入微小区内开始计时直至用户设备发送测量报告的时间，将上述时间段作为驻留时间信息，通过测量报告发送给微基站。可选的，微基站也可在用户设备在微小区内的其他时间点获取用户设备的信息，如移动时长信息以及对应的移动距离信息等。微基站可在用户设备切换进微小区时，监测该用户设备的移动轨迹，并由移动轨迹确定用户设备的移动距离；或者也可由用户设备上报用户设备的移动轨迹信息，该移动轨迹信息用于记录用户设备在微小区内的移动轨迹等，微基站可基于该移动轨迹信息确定用户设备在微小区内的移动距离，微基站可根据该移动轨迹信息及驻留时间，计算出用户设备在微小区的平均速度。若微基站确定平均速度达到预设高速阈值，则微基站可确定该用户设备为高速用户设备。其中，预设高速阈值可基于微小区大小、用户设备的移动能力或移动条件等参数确定。
步骤S403，所述微基站确定所述用户设备为高速用户设备后，所述微基站向所述宏基站发送第一消息，所述第一消息用于请求所述宏基站更改宏小区 内的高速用户设备发送测量报告的触发条件。
在一个实施例中，当微基站确定用户设备为高速用户设备后，微基站可向宏基站发送第一消息，该第一消息用于请求宏基站更改宏小区内的高速用户设备发送测量报告的触发条件，进而增加上述高速用户设备切换小区的难度。其中，宏基站更改高速用户设备发送测量报告的触发条件的具体实现方式可参见图6所示实施例中的具体描述，在此暂不赘述。
可选的，微基站与宏基站可协商发送更改请求的发送周期，微基站在发送周期期满时向宏基站发送更改请求；或者，微基站判断出用户设备为高速用户设备后，立即向宏基站发送更改请求；或者，微基站检测出经过微小区的高速用户设备的数量达到预设数量阈值时，则微基站向宏基站发送更改请求。
本发明实施例中，微基站可通过多种方式确定经过微小区的用户设备是否为高速用户设备，当确定经过微小区的用户设备为高速用户设备后，可向宏基站请求增加宏小区内的高速用户设备切换进该微小区的难度。通过上述方式，可精确判断经过微小区的用户设备是否为高速用户设备，从而可进一步降低在经过微小区时高速用户设备的切换频率，保证了高速用户设备的通信质量。
请参阅图5，图5是本发明实施例公开的又一种小区切换方法的流程示意图。如图5所示，该方法可包括以下步骤。
步骤S501，所述微基站向用户设备发送控制信息，所述控制信息携带有预设高速阈值。
在一个实施例中，微基站可向该用户设备发送控制信息，其中，该控制信息携带有预设高速阈值。进而，用户设备可自行判断用户设备的移动速度是否超过预设高速阈值。
步骤S502，所述用户设备接收所述控制信息后，判断用户设备的移动速度是否达到所述预设高速阈值。
在一个实施例中，当用户设备接收到上述控制信息后，可判断该用户设备的移动速度是否达到预设高速阈值。具体的，用户设备可确定一定时间内的用户设备的平均移动速度，如用户设备即将切换出微小区，或用户设备向微基站发送测量报告时，用户设备确定从切换进微小区到用户设备切换出微小区的时间内该用户设备的平均移动速度，并判断该平均移动速度是否达到预设高速阈值，若判断出平均移动速度达到预设高速阈值，则向微基站发送确认信息，该 确认信息用于确认用户设备的移动速度达到预设高速阈值；或者，用户设备实时监测移动速度，当监测到移动速度达到预设高速阈值时，即可向微基站发送确认信息，或者，当用户设备监测到移动速度达到预设阈值的次数超过预设次数时，向微基站发送确认信息。
步骤S503，若所述用户设备判断出所述移动速度达到预设高速阈值，向所述微基站发送确认信息，所述确认信息用于确认用户设备的移动速度达到预设高速阈值。
步骤S504，若所述微基站获取的所述用户设备的信息为确认信息时，所述微基站确定所述用户设备为高速用户设备，并且所述微基站向宏基站发送第一消息，所述第一消息用于请求所述宏基站更改宏小区内的高速用户设备发送测量报告的触发条件。
在一个实施例中，若微基站获取的用户设备的信息为确认信息，则微基站确定该用户设备为高速用户设备。可选的，微基站可通过用户设备发送的测量报告获取该确认信息，即用户设备发送的测量报告中携带有确认信息。进一步的，微基站向宏基站发送第一消息，该第一消息用于请求更改宏小区内的高速用户设备发送测量报告的触发条件，进而增加高速用户设备切换进微小区的难度。其中，宏基站更改宏小区内的高速用户设备发送测量报告的触发条件的具体实现方式可参见图6所示实施例中的具体描述，在此暂不赘述。
本发明实施例中，微基站通过向用户设备发送控制信息，能够快速的确认微小区内是否存在高速用户设备，进而可及时请求宏基站更改用户设备切换进微小区的触发条件。可进一步降低在经过微小区时高速用户设备的小区切换频率，保证了高速用户设备的通信质量。
请参阅图6，图6是本发明实施例公开的又一种小区切换方法的流程示意图。如图6所示，该方法应用于宏基站。该方法可包括以下步骤。
步骤S601，宏基站接收微基站发送的第一消息，所述第一消息用于请求所述宏基站更改所述宏基站所服务的宏小区内的高速用户设备发送测量报告的触发条件。
在一个实施例中，宏基站接收微基站发送的第一消息，该第一消息用于请求所述宏基站更改宏小区内的高速用户设备发送测量报告的触发条件。具体的，宏基站接收到微基站发送的第一消息后，获知微小区内存在高速用户设备或者 已经有高速用户设备经过微小区，则宏基站需要增加宏小区内的高速用户设备切换进微小区的难度。可选的，宏基站可通过更改测量控制信息中的配置参数，来更改上述宏小区内的高速用户设备发送测量报告的触发条件。如在LTE或LTE-A系统中，用户设备基于宏基站发送的测量控制信息中的配置参数(即偏置量)以及接收到的基站信号质量，来确定是否满足上报测量报告的触发条件，其中，不同的事件Ax对应不同的触发条件，以事件A3为例，若用户设备确定满足A3对应的触发条件，则通过测量报告上报事件A3。
步骤S602，所述宏基站确定出所述宏小区内的高速用户设备后，更改所述测量控制信息中的配置参数。
在一个实施例中，宏基站确定宏小区内的高速用户设备后，宏基站基于该更改请求，更改测量控制信息中的配置参数。其中，所述配置参数可包括幅度迟滞参数和/或时间迟滞参数。可选的，宏基站确定宏小区内的高速用户设备可参见微基站确定微小区内的高速用户设备的方式。在此，微基站与宏基站确定高速用户设备的准则相同，也就是说，微基站与宏基站可共同确定预设高速阈值或高速等级的标准。
具体的，以LTE系统中事件A3的触发条件为例，如图7所示，曲线1表示用户设备测量到的邻小区的信号强度(measurement result of the neighbouring cell,Mn)曲线，本发明实施例即为微小区的信号强度；曲线2表示邻小区的信号强度附加幅度迟滞参数后的曲线，其中，对于Mn的幅度迟滞参数可包括Ofn(frequency specific offset of the frequency of the neighbor cell，邻小区频率的特定频率偏置)、Ocn(cell specific offset of the neighbor cell，邻小区的特定小区偏置)、Hys(hysteresis parameter for this event，所述事件的迟滞参数)，曲线2可具体表示为Mn+Ofn+Ocn-Hys；曲线3表示用户设备测量到的服务小区的信号强度(mesurement result of the service cell，Ms)曲线，本发明实施例为宏小区的信号强度；曲线3表示服务小区的信号强度附加幅度迟滞参数后的曲线，其中，对于Ms的幅度迟滞参数可包括Ofs(frequency specific offset of the service frequency，服务小区频率的特定频率偏置)、Ocs(cell specific offset of the service cell，服务小区的特定小区偏置)、Off(offset parameter for this event，所述事件的补偿参数)，曲线4可具体表示为Ms+Ofs+Ocs+off。其中，事件A3的触发条件为Mn+Ofn+Ocn-Hys＞Ms+Ofs+Ocs+off。具体的，在t1时刻， 用户设备测量到Mn+Ofn+Ocn-Hys＝Ms+Ofs+Ocs+off，当经过TTT(time to trigger，时间迟滞参数)时长后，即在t2时刻，用户设备向宏基站发送测量报告。
宏基站更改配置参数，可具体更改上述幅度迟滞参数和/或时间迟滞参数。如，当宏基站更改幅度迟滞参数时，宏基站可更改Ocs参数，也可更改Ocn参数。如图8所示，曲线2及曲线3代表宏基站未更改配置参数之前，用户设备测量到的宏小区及微小区信号强度加设未更改的配置参数的曲线；当宏基站减小Ocn参数以及增加Ocs参数后，用户设备测量到的宏小区信号强度加设更改后的配置参数曲线为曲线5，用户设备测量到的微小区信号强度加设更改后的配置参数曲线为曲线6。在宏基站未更改配置参数前，用户设备在t1时刻满足触发条件，并经过TTT1时长后，即在t3时刻向宏基站发送测量报告。而在宏基站更改配置参数后，高速用户设备需要在t2时刻才能满足触发条件，因此增加了对高速用户设备满足触发条件的迟滞，避免高速用户设备切换进微小区。或者，还可通过增加时间迟滞参数的方式，增加对高速用户设备满足触发条件的迟滞，如宏基站更改配置参数后，当其在t3时刻确定满足触发条件，需要经过TTT1时长后，即在t4时刻向宏基站发送测量报告，若宏基站将TTT的时长从TTT1增加至TTT2后，用户设备要在t5时刻才能够发送测量报告，从而进一步增加了宏小区内的高速用户设备发送测量报告的难度。由于宏基站更改配置参数后，增加了宏小区内的高速用户设备发送测量报告的迟滞时间，在此时间内，上述高速用户设备有可能已经经过了微小区，从而，避免了用户设备将服务小区切换至微小区内。
可选的，宏基站对配置参数的更改量可基于微基站通知的进入微小区的高速用户设备的数量确定。其中，微基站在发送给宏基站的更改请求中可携带确定的高速用户设备的数量信息，如当微基站判断出的高速用户设备的数量达到预设数量阈值，触发向宏基站发送第一消息时，微基站在第一消息中可携带高速用户设备的数量信息；又如当微基站基于预设周期向宏基站发送更改请求时，微基站也可在第一消息中携带高速用户设备的数量信息。宏基站可确定配置参数的基础更改量，如确定的基础更改量为k，其中，可针对不同的配置参数，确定不同的基础更改量k；则宏基站可根据接收到的高速用户设备的数量信息及基础更改量k确定配置参数的更改量，确定配置参数的更改量后，则可确定 如图8所示的曲线5或曲线6分别距离曲线2或曲线3的位置。
可选的，宏基站对配置参数的更改量还可基于微基站上报的高速用户设备的高速等级进行确定。其中，当微基站判断出微小区内存在用户设备为高速用户设备后，还可进一步确定该高速用户设备的高速等级，如微基站可根据高速用户设备的移动速度或上报的速度等级信息确定高速用户设备的高速等级为一级、二级等，其中，级数越大，则表明该高速用户设备的移动速度越快。每一级高速等级可对应高速用户设备的一个移动速度范围。微基站发送的第一请求中可携带其确定的高速用户设备的高速等级，从而，宏基站可针对该高速等级确定更改量，如更改量可与高速等级成正相关关系等。
可选的，宏基站还可结合上述两种方式，即宏基站基于微基站发送的更改请求中携带的高速用户设备数量信息及高速用户设备的高速等级信息，确定对配置参数的更改量。
可选的，宏基站还可接收到一次微基站发送的第一消息后，对配置参数进行一次更改；当下次接收到微基站发送的更改请求后，可继续对配置参数进行更改，其中，本次对配置参数的更改量可与上次配置参数的更改量相同，也可不同，直至不再接收到微基站发送的第一消息，表明彻底杜绝了宏小区内的高速用户设备切换进微小区的现象。
步骤S603，所述宏基站将携带所述更改后的配置参数的测量控制信息发送给宏小区内的高速用户设备。
在一个实施例中，宏基站可将携带更改后的配置参数的测量控制信息发送给宏小区内的高速用户设备，使宏小区内的高速用户设备基于更改后的配置参数确定能够上报测量报告的触发条件。
可选的，宏基站还可将所述测量控制信息发送给宏小区内的所有用户设备。
本发明实施例中，宏基站通过在接收到微基站发送的更改请求后，更改用于影响高速用户设备发送测量报告的触发条件的配置参数，可增加高速用户设备切换进微小区的难度，进而降低在经过微小区时高速用户设备的小区切换频率，保证了高速用户设备的通信质量。
