Definitions

  • the present invention relates to the field of communications, and in particular to a pre-handover processing method, apparatus, user equipment, and cell.
  • BACKGROUND OF THE INVENTION When smart phones bring fun and convenience to people's lives, data traffic has also increased dramatically, especially in densely populated locations such as commercial centers and residential areas, where single cell planning has become difficult and steep. The traffic is matched, which seriously affects the user experience.
  • 3GPP has proposed the HetNet topic, that is, adding micro cells in an existing macro cell, thereby increasing the capacity of the network to meet the increasing amount of packet data.
  • a series of new problems have been introduced at the same time as the introduction of micro cells, and the robustness of switching between macro cells and micro cells is one of the representative problems. In the related art, the switching is performed as follows:
  • the physical layer of the UE reports the internal measurement result to the radio resource control (Radio Resource Control, referred to as RRC) layer;
  • RRC Radio Resource Control
  • the RRC layer performs layer 3 filtering on the result reported by the physical layer, and filters the value and reference. The value is compared to determine whether the A3 event (Event A3) can be triggered. If the A3 event is triggered, the TTT (Time-to-Trigger) timer is started.
  • RRC Radio Resource Control
  • the UE sends a measurement report (Measurement Report, MR for short) to the eNodeB after the TTT timer expires. ;
  • the source cell (the current serving cell of the UE) initiates a handover preparation process with the handover target cell included in the MR, and receives a handover command sent by the target cell through the X2 interface (Handover Command, referred to as HO CMD );
  • the source cell sends the HO CMD to the UE;
  • S6 after receiving the HO CMD sent by the source cell, the UE initiates a handover process to the handover target cell, that is, initiates a random access procedure, and completes the target to the target Cell handover.
  • TTT Time of Handover Preparation procedure, which does not include signaling transmission and processing time.
  • a UE For a UE that still uses a macro cell (ie, a source cell) as a serving cell, if the UE waits for a long time according to the current protocol, the UE is likely to go deep into the micro cell, so that the interference of the micro cell is too large to be correct.
  • the HO CMD sent by the source cell is received or cannot be received, which causes the handover to fail, which seriously affects the robustness of the UE handover, thereby affecting the performance of the network.
  • the UE moves from the micro cell to the macro cell, since the cell radius of the micro cell is small, the signal strength of the macro cell (ie, the target cell) rapidly increases.
  • the UE For a UE that still serves as a serving cell in the micro cell (ie, the source cell), if the UE waits for a long time according to the current protocol, the UE is likely to go deep into the macro cell, so that the macro cell is too large to be correct. Receiving or failing to receive the HO CMD sent by the micro cell, causing the handover to fail, thereby affecting network performance. The above situation is more obvious when the UE runs faster.
  • the above switching process is mainly described by taking the A3 event as an example.
  • measurement events include A1 event (EventAl), A2 event (EventA2), A4 event (Event A4), A5 event (Event A5), A6 event (Event A6), Bl.
  • Event (B) and Event B2 (Event B2) these events may also trigger the switching process, which in turn will face the problems described in the above examples.

Description

预切换处理方法、 装置、 用户设备及小区 技术领域 本发明涉及通信领域， 具体而言， 涉及一种预切换处理方法、 装置、 用户设备及 小区。 背景技术 智能手机在给人们的生活带来乐趣和便利的时候， 也使数据业务量剧增， 尤其是 在商业中心、 居民住宅区等人口稠密的地点， 单一的小区规划已经很难与陡增的业务 量匹配， 从而严重的影响到用户体验。 为了解决这些问题， 3GPP提出了 HetNet课题， 即在现有的宏小区内增设微小区， 从而增加网络的容量， 以满足日益增长的分组数据 量。 但是， 在引入微小区的同时也引入了一系列新的问题， 其中， 宏小区与微小区之 间切换的健壮性就是代表性问题之一。 在相关技术中， 切换是按照如下过程进行的：
S1 , UE的物理层将内部的测量结果上报给无线资源控制（Radio Resource Control, 简称为 RRC) 层； S2， RRC层对物理层上报的结果进行层 3过滤， 并且将过滤后的值与参考值进行 对比， 判断是否能够触发 A3事件 （Event A3 )， 则如果触发了 A3事件， 则启动 TTT (Time-to-Trigger) 定时器；
S3 , 如果在 TTT定时器运行期间， 经层 3过滤后的物理层上报的值都满足 A3事 件触发的条件， 则 UE在 TTT定时器超时后向 eNodeB发送测量报告 （Measurement Report, 简称为 MR);
S4， 源小区 （UE当前的服务小区） 则收到 MR后， 发起与 MR中包含的切换目 标小区之间的切换准备过程， 并且通过 X2 接口接收目标小区发送的切换命令 ( Handover Command， 简称为 HO CMD )；
S5， 在切换准备过程完成之后， 源小区向 UE发送 HO CMD; S6， 在收到源小区发送的 HO CMD后， UE向切换目标小区发起切换过程， 即发 起随机接入过程， 并且完成向目标小区的切换。 在相关技术的切换过程中， 从 A3 事件触发到发送切换命令之间要经历很长的时 间（即 TTT + Time of Handover Preparation procedure,未包括信令的传输和处理时间）。 在 HetNet场景中， 当 UE从宏小区向微小区移动时， 因为微小区的小区半径较小， 所 以， 微小区 （即目标小区） 的信号强度就会快速上升。 对于以仍然以宏小区 （即源小 区）为服务小区的 UE来说， 如果按照现行协议进行长时间的等待的话， UE很可能会 深入微小区， 以至于因为微小区的干扰过大而无法正确接收或者无法接收源小区发送 的 HO CMD, 从而导致切换失败， 严重的影响到 UE切换的健壮性， 从而影响到网络 的性能。 反之， 当 UE从微小区向宏小区移动时， 因为微小区的小区半径较小， 所以， 宏小区 （即目标小区） 的信号强度就会快速上升。 对于以仍然以微小区 （即源小区） 为服务小区的 UE来说， 如果按照现行协议进行长时间的等待的话， UE很可能会深入 宏小区，以至于因为宏小区的干扰过大而无法正确接收或者无法接收微小区发送的 HO CMD, 从而导致切换失败， 进而影响网络性能。 上述情况在 UE运行速度较快时更为 明显。 另外， 上述切换过程主要以 A3事件为例进行描述。在现行的协议中， 除了 A3事 件之外， 测量事件还包括 A1事件（EventAl )、 A2事件（EventA2)、 A4事件（Event A4)、 A5事件（ Event A5)、 A6事件（ Event A6)、 Bl事件（Event Bl )禾 P B2事件（Event B2)， 这些事件也都可能引发切换过程， 进而也都会面临上述例子中所述的问题。 因此， 在相关场景中的小区间切换， 存在切换成功率低、 切换健壮性差的问题。 发明内容 本发明提供了一种预切换处理方法、 装置、 用户设备及小区， 以至少解决在相关 技术中的小区间切换， 存在切换成功率低， 以及切换健壮性差的问题。 根据本发明的一个方面， 提供了一种预切换处理方法， 包括： 用户设备 UE接收 服务小区发送的预切换目标小区配置信息； 所述依据所述预切换目标小区配置信息执 行预切换过程。 优选地， 在所述 UE接收服务小区发送的预切换目标小区配置信息之前， 还包括： 所述 UE向所述服务小区发送预切换指示信息， 其中， 所述预切换指示信息用于触发 所述服务小区生成并向所述

下面结合附图对本发明实施例的优选实施例进行说明。 图 13是根据本发明优选实施例的预切换处理方法的流程图， 如图 13所示， 该方 法包括如下步骤： 首先， 需要说明的是， 在本优选实施方式中， UE的处于小区 A中， 并且小区 A 为 UE的服务小区。 步骤 S1302, 小区 A发起与邻区之间的切换准备过程。 在本优选实施方式中， 小区 A可以在以下情况下至少之一发起与邻区之间的切换 准备过程： 小区 A接收到 UE发送的预切换指示信息； 小区 A接收到邻区发送的切换 准备指示信息；小区 A根据自身对 UE的移动性统计信息判断应该发起切换准备过程; 小区 A根据自身的负载状况判断应该发起切换准备过程。 在本优选实施方式中， 当小区 A接收到 UE发送的预切换指示信息时， 对于该指 示信息中包含的邻区信息， 小区 A可以分别发起与所有邻区之间的切换准备过程， 或 者， 发起与预定数量的、 信号质量最好的邻区之间的切换准备过程， 或者发起与特定 类型的邻区之间的切换准备过程。 当小区 A收到邻区发送的切换准备指示信息时， 小 区 A依据该指示信息， 发起与该小区之间的切换准备过程。 当根据自身对 UE的移动 性统计信息判断应该发起切换准备过程时， 小区 A发起与所确定的 UE可能的预切换 目标小区之间的切换准备过程。当根据自身的负载状况判断应该发起切换准备过程时， 小区 A发起与 UE邻近的、 负载较轻的小区之间的切换准备过程。 在本优选实施方式中， UE发送的预切换指示信息可以为以下至少之一： 满足 A3 事件进入条件的邻区标识； 满足 A3事件进入条件的邻区类型； 满足 A3事件进入条件 的邻区的测量结果信息； 小区 A的测量结果信息。 在本优选实施方式中， 邻区发送的切换准备指示信息可以为以下内容之一或是之 间的任意组合： UE的标识； 该邻区标识； 该邻区类型； 该邻区的信号强度信息； 切换 准备触发标识。 步骤 S1304, 小区 A生成并发送预切换目标小区配置信息。 在本优选实施方式中， 当小区 A完成与邻区之间的切换准备过程后， 根据从邻区 获得的信息生成预切换目标小区配置信息， 并且发送给 UE。其中， 该预切换目标小区 配置信息可以为以下内容之一或是其之间的任意组合： UE在每个完成与小区 A之间 的切换准备过程的邻区中的配置信息； UE在预定数量的、完成与服务小区之间切换准 备过程的、 测量结果最优的邻区中的配置信息； UE发起切换过程时间指示信息。 其中， UE发起切换过程的时间指示信息可以为具体的时间点、 时间段， 也可以是 指示 UE自行确定发起切换过程的具体时刻。 步骤 S1306, UE接收预切换目标小区配置信息， 设置预切换目标小区， 并且确定 切换发起时间。 在本优选实施方式中，当预切换目标小区配置信息中仅仅包含一个小区的配置时， UE将该小区设定为预切换目标小区；当预切换目标小区配置信息中包含多于一个的小 区配置时， UE从中随机选择一个作为预切换目标小区，或者依据测量信号的质量选择 最强的小区作为预切换目标小区。 在本优选实施方式中， 若预切换目标小区配置信息中的切换过程时间指示信息指 明了具体的时间点， 则 UE将在具体的时间点发起切换操作， 即执行步骤 S1308; 若 指明了具体的时间段， 则 UE将在该时间段内发起切换过程， 即执行步骤 S1310; 若 指示 UE自行确定切换发起时间，或者预切换目标小区中没有切换过程时间指示信息， 则 UE立即发起切换操作， 即执行步骤 S1312, 或者根据测量报告的发送情况和切换 命令的接收情况判断是否发起， 以及如何执行切换过程： 若 UE没有发送测量报告， 则执行步骤 S1314, 若 UE发送了测量报告， 则执行步骤 S1316。 步骤 S1308, UE在网络指定的时间点向预切换目标小区发起切换过程； 步骤 S1310, UE在网络指定的时间段内向预切换目标小区发起切换过程； 步骤 S1312, UE在接收到预切换小区配置信息之后， 立即向预切换目标小区发起 切换过程； 步骤 S1314, UE没有发送测量报告， 则 UE不会发起切换操作； 在本优选实施方式中， UE最终未发送测量报告， 即在 TTT定时器运行期间， UE 对所有邻区的测量结果未能一直满足 A3事件的进入条件，则 UE不发起切换过程， 即 UE不会以预切换目标小区配置信息为依据发起切换过程。 步骤 S1316, UE发送了测量报告， 并且根据切换命令的接收结果发起切换过程。 在本优选实施方式中， UE最终发送了测量报告， 即在 TTT定时器运行期间， UE 对所有邻区的测量结果中至少有一个一直满足 A3事件的进入条件，则 UE等待接收切 换命令： 若 UE接收到了切换命令，则 UE根据该切换命令发起切换过程； 若 UE未能正确 接收切换命令： 若测量报告中包含的切换目标小区也包含在预切换目标小区配置中， 则 UE以该小区为目标小区， 依据预切换目标小区配置中包含的内容发起切换过程； 或者， UE根据预切换目标小区配置信息，向之前设定的预切换目标小区发起切换过程。 在本优选实施方式中， 小区 A的基站接收到 UE发送的测量报告后将会执行切换 准备过程， 并且根据该结果发送切换命令， 其中， 上述切换准备过程可以为以下两种 情况至少之一： 情况一， 若测量报告中包含的邻区信息与预切换指示信息中包含的邻 区信息有重叠， 则对于重叠的邻区信息， 小区 A的基站不再执行新的切换准备过程， 而是依据预切换过程中的切换准备过程的结果生成切换命令； 情况二， 无论测量报告 中包含的邻区信息与预切换指示信息中包含的邻区信息是否有重叠， 小区 A的基站都 将依据测量报告中的邻区信息发起新的切换准备过程， 并且根据该过程的结果生成切 换命令。 其中， UE未能正确接收切换命令可以是以下情况至少之一： UE在预定时间内未 能接收到切换命令； UE接收到了切换命令但是未能正确获取其中包含的内容。 在上述优选实施方式中， 对于预切换过程中的切换准备过程涉及到的小区基站获 取的 UE上下文， 以及为 UE预留的资源， 可以采用以下方式至少之一进行处理： 方 式一， 预切换过程中涉及到的小区基站在预定时间内保留 UE上下文和为该 UE所预 留的资源， 在超过预定时间后， 小区释放该预留资源， 并且删除 UE上下文， 或者仅 仅释放预留资源， 但是保留 UE上下文； 方式二， 在 UE完成切换过程、 进入新的小 区后， 其源小区向除了 UE当前服务小区以外的、 预切换过程涉及到的小区发送指示 信息， 这些小区在收到指示信息后释放预留资源， 并且删除 UE上下文， 或者仅仅释 放上述预留资源， 但是保留 UE上下文。 下面结合上述优选实施例对预切换处理的优选实施方式进行说明。 优选实施方式一： 图 14是根据本发明优选实施方式一的预切换处理方法的流程图， 如图 14所示， 在本优选实施方式中， UE处于小区 A中， 并且小区 A为 UE的服务小区， UE的物理 层对 UE能够检测到的所有小区进行测量， 并且根据测量结果发起预切换过程。 该流 程包括如下步骤： 步骤 S1402， UE对邻区进行测量， 当有邻区满足 A3事件进入条件时， 启动 TTT 定时器， 并且向小区 A发送预切换指示信息。 其中， UE 发送的预切换指示信息为以下内容之一或以下内容的任意组合：

量结果最好的邻区的测量结果信息。 步骤 S1404, 小区 A的基站接收 UE发送的预切换指示信息， 并且根据该信息发 起切换准备过程。 在接收到 UE发送的预切换指示信息后， 小区 A的基站根据该信息中包含的邻区 信息发起切换准备过程。 其中， 具体处理过程可以为以下至少之一： 对于预切换目标 小区信息中包含的邻区信息， 小区 A的基站分别发起与所有邻区之间切换准备过程； 小区 A的基站仅仅针对预定数量的、 信号质量最好的邻区发起切换准备过程。 小区 A 的基站仅仅针对特定类型的邻区发起切换准备过程。 步骤 S1406, 小区 A的基站生成并且向 UE发送预切换目标小区配置信息。 在本优选实施方式一中， 当小区 A完成与邻区之间的切换准备过程后， 根据从邻 区获得的信息生成预切换目标小区配置信息， 并且发送给 UE。其中， 预切换目标小区 配置信息可以为以下至少之一或是以下内容的任意组合： UE在每个完成与小区 A之 间的切换准备过程的邻区中的配置信息； UE在预定数量的、完成与服务小区之间切换 准备过程的邻区中的配置信息； UE发起切换过程的时间指示信息， 其中， 该 UE发起 切换过程的时间指示信息指示 UE自行确定发起切换过程的具体时刻。 步骤 S1408, UE接收预切换目标小区配置信息， 设置预切换目标小区， 并且确定 切换发起时间。 在本优选实施方式一中， 当预切换目标小区配置信息中仅仅包含一个小区的配置 时， UE将该小区设定为预切换目标小区； 当预切换目标小区配置信息中包含多于一个 的小区配置时， UE从中随机选择一个作为预切换目标小区，或者依据测量信号的质量 选择最强的小区作为预切换目标小区。 在本优选实施方式一中， 关于时间指示信息可以包括以下两种情况： 情况一， 预 切换目标小区配置信息中包含了时间指示信息，并且指示 UE自行确定切换发起时间； 情况二， 预切换目标小区配置信息中没有时间指示信息。 基于上述两种情况， UE可以立即发起切换操作， 即执行步骤 S1410, 或者根据测 量报告的发送情况判断是否发起， 以及如何执行切换过程： 若 UE没有发送测量报告， 则执行步骤 S1412, 若 UE发送了测量报告， 则执行步骤 S1414。 步骤 S1410, UE在接收到预切换小区配置信息之后， 立即向预切换目标小区发起 切换过程； 步骤 S1412, UE没有发送测量报告， 则 UE不会发起切换操作； 在本优选实施方式一中， UE最终未发送测量报告， 即在 TTT定时器运行期间，
UE对邻区的测量结果未能一直满足 A3事件的进入条件， 则 UE不发起切换过程， 即 UE不会以预切换目标小区配置信息为依据发起切换过程。 步骤 S1414, 小区 A的基站接收测量报告， 执行切换准备过程， 并且发送切换命 令。 在本优选实施方式一中， 小区 A的基站接收到 UE发送的测量报告后将会执行切 换准备过程， 并且根据该结果发送切换命令， 其中， 切换准备过程可以为以下两种情 况之一： 若测量报告中包含的邻区信息与预切换指示信息中包含的邻区信息有重叠， 则对 于重叠的邻区信息， 小区 A的基站不再执行新的切换准备过程， 而是依据预切换过程 中的切换准备过程的结果生成切换命令； 无论测量报告中包含的邻区信息与预切换指示信息中包含的邻区信息是否有重 叠， 小区 A的基站都将依据测量报告中的邻区信息发起新的切换准备过程， 并且根据 该过程的结果生成切换命令。 步骤 S1416: UE发送了测量报告， 并且根据切换命令的接收结果发起切换过程。 在本优选实施方式一中， UE最终发送了测量报告， 即在 TTT定时器运行期间，
UE对邻区的测量结果一直满足 A3事件的进入条件， 则 UE等待接收切换命令： 若 UE接收到了切换命令， 则 UE根据该切换命令发起切换过程； 若 UE未能正确接收切换命令： 若测量报告中包含的切换目标小区也包含在预切 换目标小区配置中， 则 UE以该小区为目标小区， 依据预切换目标小区配置中包含的 内容发起切换过程； 或者， UE根据预切换目标小区配置信息， 向之前设定的预切换目 标小区发起切换过程。 在本优选实施方式一中， UE未能正确接收切换命令可以包括以下情况至少之一：
UE在预定时间内未能接收到切换命令； UE接收到了切换命令但是未能正确获取其中 包含的内容。 在上述优选实施方式一中，预切换过程中涉及到的小区基站在预定时间内保留 UE 上下文和为该 UE所预留的资源， 在超过预定时间后， 小区释放该预留资源， 并且删 除 UE上下文， 或者仅仅释放预留资源， 但是保留 UE上下文。 图 15是根据本发明优选实施方式二的预切换处理方法的流程图， 如图 15所示， 在本本优选实施方式中， UE处于小区 B中， 并且小区 B为 UE的服务小区， 而小区 C 和小区 D为小区 B的两个邻区。 其中， 小区 C和小区 D可以根据自身的算法或者自 身对 UE的测量对 UE的移动进行预判。 该预切换过程包括如下步骤： 步骤 S1502, 小区 C和小区 D分别向 UE的服务小区 B发送切换准备指示信息； 在本优选实施方式二中， 小区 C和小区 D可以根据自身的算法或者自身对 UE的 测量对 UE的移动进行预判， 并且向 UE的服务小区发送切换准备指示信息。 其中， 该切换准备指示信息用于通知小区 B其覆盖范围内的某个具体 UE可能会进入指示信 息发送小区。 在本优选实施方式中， 小区 C和小区 D可能同时发送各自的切换准备指示信息， 也可能先后发送切换准备指示信息。 在本优选实施方式中， 邻区发送的切换准备指示信息可以为以下内容之一或其之 间的任意组合： UE的标识； 该邻区标识； 该邻区类型； 该邻区的信号强度信息； 切换 准备触发标识。 步骤 S1504, 小区 B接收小区 C和小区 D发送切换准备指示信息， 并且发起切换 准备操作； 在本优选实施方式二中，小区 B在收到小区 C和小区 D的切换指示信息后，会分 别发起与这两个小区的切换准备过程， 而不会考虑接收到切换指示信息的先后顺序。 步骤 S1506, 小区 B生成并且发送预切换目标小区配置信息。 在本优选实施方式中， 小区 B在完成了与小区 C和小区 D的切换准备过程之后， 根据两个切换准备过程的结果生成预切换目标小区配置信息， 即该预切换目标小区配 置信息中包含了 UE在小区 C中的配置信息和 UE在小区 B中的配置信息。 另外， 在本优选实施方式二中， 预切换目标小区配置信息包含了切换过程的时间 指示信息， 即向 UE指示发起切换过程的时间指示信息为具体的时间点。 步骤 S1508, UE接收预切换目标小区配置信息， 设置预切换目标小区， 并且确定 切换发起时间。 在本优选实施方式二中， 预切换目标小区配置信息中包含两个小区 （小区 C和小 区 D) 的配置信息， 则 UE从中随机选择一个作为预切换目标小区， 或者依据测量信 号的质量选择最强的小区作为预切换目标小区。 若预切换目标小区配置信息中仅仅包 含一个小区的配置信息时， UE将该小区设定为预切换目标小区。在本优选实施方式二 中， UE将小区 C作为预切换目标小区。 在本优选实施方式二中， 预切换目标小区配置信息中指明了切换发起的具体的时 间点， 则 UE将在该具体的时间点发起切换操作， 执即行步骤 S1510。 步骤 S1510, UE在网络指定的时间点向预切换目标小区发起切换过程。 在本优选实施方式二中， UE以与切换目标小区配置信息为依据，在网络指定的时 间点， 向选定的预切换目标小区 （小区 C) 发起切换操作。 在本优选实施方式二中， 当 UE完成切换过程、 进入小区 C后， 小区 B向小区 D 发送指示信息， 小区 D在收到指示信息后释放切换准备过程中预留的资源， 并且删除 UE上下文， 或者仅仅释放预留资源， 但是保留 UE上下文。 图 16是根据本发明优选实施方式三的预切换处理方法流程图， 如图 16所示， 在 本优选实施方式三中， 小区 E为 UE的服务小区， 小区 F为小区 E的一个邻区， UE 处于小区 E的覆盖范围内， 并且其所处位置接近小区 E的边缘， 靠近小区！^。 在本优 选实施方式中， UE的服务小区 E能够根据对某个具体 UE的移动性统计信息对 UE的 移动进行预判， 同时， 也能够根据自身的负载状况将处于小区边缘或者覆盖重叠区的 UE切换到相应的邻区中。 该流程包括如下步骤： 步骤 S1602, 小区 E判断应该将 UE切换至其邻区接受服务； 在本优选实施方式三中， 对于处于小区 E边缘的 UE， 小区 E根据其自身的对 UE 移动性信息的统计或者根据其自身的负载状况， 决定应当改变 UE的服务小区， 使其 接受小区 E的邻区的服务。 步骤 S1604, 小区 E选定邻区， 并且发起切换准备过程； 在本优选实施方式三中， 因为 UE接近小区 E的边缘， 并且靠近小区 F， 所以， 小区 E选定小区 F， 并且发起与小区 F的切换准备过程。 步骤 S1606, 小区 E生成并且发送预切换目标小区配置信息。 在本优选实施方式三中， 小区 E在完成了与小区 F的切换准备过程之后， 根据切 换准备过程的结果生成预切换目标小区配置信息， 即该预切换目标小区配置信息中包 含了 UE在小区 F中的配置信息。 另外， 在本优选实施方式三中， 预切换目标小区配置信息包含了切换过程的时间 指示信息， 即向 UE指示发起切换过程的时间指示信息为具体的允许发起切换的时间 段。 步骤 S1608, UE接收预切换目标小区配置信息， 设置预切换目标小区， 并且确定 切换发起时间。 在本优选实施方式三中， 预切换目标小区配置信息中仅包含一个小区 （小区 F) 的配置信息， 则 UE将小区 F设定为预切换目标小区。 在本优选实施方式三中， 预切换目标小区配置信息中指明了切换发起的具体的时 间短， 则 UE将在该时间段内发起切换操作， 执即行步骤 S1610。 步骤 S1610, UE在网络指定的时间段内向预切换目标小区发起切换过程。 在本优选实施方式三中， UE以与切换目标小区配置信息为依据，在网络指定的时 间段内， 向选定的预切换目标小区 （小区 F) 发起切换操作。 当 UE完成切换过程后， 小区 F成为该 UE的新的服务小区。 显然， 本领域的技术人员应该明白， 上述的本发明的各模块或各步骤可以用通用 的计算装置来实现， 它们可以集中在单个的计算装置上， 或者分布在多个计算装置所 组成的网络上， 可选地， 它们可以用计算装置可执行的程序代码来实现， 从而， 可以 将它们存储在存储装置中由计算装置来执行， 并且在某些情况下， 可以以不同于此处 的顺序执行所示出或描述的步骤， 或者将它们分别制作成各个集成电路模块- 它们中的多个模块或步骤制作成单个集成电路模块来实现。 这样， 本发明不限制于任 何特定的硬件和软件结合。 以上所述仅为本发明的优选实施例而已， 并不用于限制本发明， 对于本领域的技 术人员来说， 本发明可以有各种更改和变化。 凡在本发明的精神和原则之内， 所作的 任何修改、 等同替换、 改进等， 均应包含在本发明的保护范围之内。 工业实用性 通过本发明实施例及优选实施方式提供的方案， 解决了在相关技术中的小区间切 换， 存在切换成功率低， 以及切换健壮性差的问题， 进而达到了加强小区间切换的健 壮性， 提高小区间切换的成功率， 提高网络性能及用户体验的效果。
