技术领域
本公开涉及通信技术领域，尤其涉及一种小区切换方法、终端设备及原基站。
背景技术
MulteFire(MF)是一种新的基于LTE(Long Term Evolution，长期演进)的无线接入技术，该技术可以不借助授权频段载波独立运行于非授权频段中。MulteFire将LTE扩展到非授权频段中，物理层引入类似WiFi(Wireless-Fidelity，无线保真)载波监听技术的先听后说(Listen Before Talk，简称为LBT)机制，以实现与非授权频段设备公平竞争非授权频段信道，以及避免非授权频段设备之间相互干扰。在基站或终端设备监听到非授权频段信道被占用时，即LBT失败时，停止发送信号，当监听到非授权频段信道空闲时，即LBT成功时，才发送信号。
当位于Multefire小区的终端的测量结果满足切换条件时，若根据LBT机制监听到信道被占用时，将不能发送测量报告，同样的，Multefire小区收到终端的测量报告后，若根据LBT机制监听到信道被占用时，将不能发送切换命令，导致切换延时过大。
因此，Multefire系统支持一种自动切换方案，即终端检测当前接入小区和相邻小区的信道质量满足切换条件时不用等到接收当前接入小区的切换命令即可自动向目标小区发起随机接入以接入目标小区，即当终端检测当前接入小区和相邻小区的信道质量满足切换条件时不用向当前小区发送测量报告并等待当前小区的切换命令以降低切换时延。
根据相关的自动切换方案，在自动切换准备中，候选小区对UE(User  Equipment，用户设备)的RRC(Radio Resource Control，无线资源控制)配置通过自动切换准备响应由自动切换候选基站发送给基站。基站将候选小区对UE的自动切换配置发送给UE。由于在传统切换中，只有一个目标小区，UE收到目标小区配置(即切换命令)时开始切换，也即开始应用目标小区的RRC配置，在切换定时器超时之前UE接入目标小区时UE在目标小区的RRC配置都不会失效。但是在自动切换中，UE收到自动切换配置后不确定是否开始切换及何时开始切换，当UE选择自动切换的目标小区进行接入时在该目标小区中该UE的RRC配置可能已经失效，从而导致自动切换失败。
在相关技术中，针对自动切换过程中终端设备难以预知目标小区RRC配置状态的问题，目前尚未提出有效的解决方案。
发明内容

具体实施方式
下面将结合本公开的一些实施例中的附图，对本公开的一些实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
本公开的一些实施例提供一种小区切换方法，该方法应用于终端设备。本公开的一些实施例通过自动切换配置定时器监控候选小区对终端设备的无线资源控制配置的状态，从而终端设备在自动切换过程中可以实时掌握候选小区对终端设备的无线资源控制配置的状态，从而可以根据候选小区对终端设备的无线资源控制配置的状态以确定是否应用该对终端设备的无线资源控制配置接入该候选小区，例如，在候选小区对终端设备的无线资源控制配置有效时可以应用该对终端设备的无线资源控制配置接入该候选小区，在候选小区对终端设备的无线资源控制配置失效时可以不应用该对终端设备的无线资源控制配置接入该候选小区，以减少因候选小区对终端设备的无线资源控制配置失效导致切换失败的概率。
参见图1，图1为本公开的一些实施例可应用的网络结构示意图，如图1所示，包括终端设备11、原基站12和候选基站13，其中，终端设备11可以是移动电话机(或手机)，或者其它能够发送或接收无线信号的设备，包括用户设备(终端)、个人数字助理(PDA)、无线调制调解器、无线通信装置、手持装置、膝上型计算机、无绳电话、无线本地回路(WLL)站、能够将移动信号转换为wifi信号的客户驻地设备(CPE)或Mifi、智能家电、或其它不通过人的操作就能自发与移动通信网络通信的设备等。需要说明的是，在本公开的一些实施例中并不限定设备终端11的具体类型。终端设备11可以与 原基站12建立通信，原基站12可以和候选基站13建立通信，附图中的网络可以表示终端设备11与原基站12无线建立通信，原基站12和候选基站13无线建立通信，原基站12和候选基站13可以是演进型基站(evolved Node B，简称为eNB)或者其他基站，需要说明的是，在本公开的一些实施例中并不限定原基站12和候选基站13的具体类型。
参见图2，图2是本公开的一些实施例提供的小区切换方法的流程图，如图2所示，包括以下步骤201-203。
步骤201、终端设备接收原基站发送的自动切换配置信息和自动切换配置定时器信息，所述自动切换配置信息包括候选小区对所述终端设备的无线资源控制配置。
本公开的一些实施例中，自动切换配置信息包括候选小区对终端设备的无线资源控制配置，上述候选小区可以是一个候选小区或是至少两个候选小区。上述候选小区对终端设备的无线资源控制配置可以包括3种类型：仅为终端设备配置小区信息；仅为终端设备配置小区信息和公共RRC(Radio Resource Control，无线资源控制)配置；为终端设备配置小区信息、公共RRC配置及专用RRC配置。
其中，上述小区信息可以包括候选小区的物理小区标识和载频信息，以便于终端设备加快小区搜索速度；上述公共RRC配置可以包括候选小区的系统广播块(System Information Block，简称为SIB)，以便于终端设备获得候选小区的系统信息，降低终端设备切换到候选小区的业务中断时间；上述专用RRC配置包含终端设备在候选小区中的安全参数配置、C-RNTI(Cell Radio Network Temporary Identifier，小区无线网络临时标识)配置、专用RACH(Random Access Channel，随机接入信道)资源配置等，以便于终端设备获得在候选小区中的专用资源配置，加快终端设备完成到候选小区的切换速度。
另外，对上述前两种RRC配置类型(也即仅为终端设备配置小区信息和仅为终端设备配置小区信息和公共RRC配置)，终端设备在候选小区中不占用无线资源，终端设备仅获得候选小区的小区信息或系统广播信息，终端设备只能采用自动切换请求过程(类似RRC连接重建立过程)接入候选小区；而对第三种RRC配置类型(也即为终端设备配置小区信息、公共RRC配置 及专用RRC配置)，终端设备在候选小区中占有无线资源，终端设备可通过发送一条自动切换完成消息(类似RRC重配置完成信令)接入候选小区完成自动切换。
具体的，在自动切换准备过程中，原基站可通过向候选基站发送自动切换准备请求，以请求一个或至少两个候选基站的一个或至少两个候选小区对终端设备进行RRC配置，候选小区对终端设备的RRC配置通过自动切换准备响应由候选基站发送给原基站。
上述自动切换配置定时器信息可以是由原基站配置的，也可以是候选基站配置的，并可以通过自动切换准备响应消息发送给原基站。可选的，上述自动切换配置定时器信息可以包括自动切换配置定时器的时长，也可以包括候选小区对终端设备的RRC配置失效的绝对时间(也即候选小区对终端设备的RRC配置失效的时刻)，该绝对时间可以是协调世界时(UTC，Coordinated Universal Time)，例如，自动切换配置定时器信息包含候选小区A对终端设备的无线资源控制配置失效的时刻为UTC时间2017年7月3日08时30分30秒；或者，该绝对时间为无线通信系统的系统帧号(SFN，System Frame Number)，例如，自动切换配置定时器信息包含候选小区A对终端设备的无线资源控制配置失效的时刻为SFN为1023的时刻，从而终端设备可以根据自动切换配置定时器信息配置自动切换配置定时器。
步骤202、所述终端设备启动自动切换配置定时器。
本公开的一些实施例中，终端设备可以在接收到基站发送的自动切换配置信息时启动自动切换配置定时器，也可以在开始自动切换时(即在自动切换定时器超时时)启动自动切换配置定时器。具体的，自动切换配置定时器的时长可以根据上述自动切换配置定时器信息确定，例如，若上述自动切换配置定时器信息包括自动切换配置定时器的时长，则可以直接利用该自动切换配置定时器的时长控制自动切换配置定时器，若上述自动切换配置定时器信息包括候选小区对终端设备的RRC配置失效的时刻，则可以将所述候选小区对所述终端设备的无线资源控制配置失效的时刻与所述自动切换配置定时器的启动时刻的时间差值作为自动切换配置定时器的时长。
实际应用中，由于候选基站无法确定终端设备何时收到自动切换配置定 时器信息以及何时启动自动切换配置定时器，因此，将自动切换配置定时器信息设为候选小区对终端设备的RRC配置失效的时刻更为准确。例如，可以将自动切换配置定时器信息设为候选小区对终端设备的RRC配置失效的SFN。
需要说明的是，若候选小区为至少两个时，则可以分别为每个候选小区配置一个自动切换配置定时器，以分别监控每个候选小区对所述终端设备的无线资源控制配置的状态，也可以是为所有的候选小区均配置一个共同的自动切换配置定时器，通过共同的自动切换配置定时器监控所有候选小区对终端设备的无线资源控制配置的状态。
步骤203、若所述自动切换配置定时器超时，则所述终端设备确定所述候选小区对所述终端设备的无线资源控制配置失效。
本公开的一些实施例中，若所述自动切换配置定时器超时，则所述终端设备确定所述候选小区对所述终端设备的无线资源控制配置失效，若自动切换配置定时器未超时，则所述终端设备可以确定所述候选小区对所述终端设备的无线资源控制配置尚未失效。可选的，终端设备可以通过不同的标识以表示候选小区对所述终端设备的无线资源控制配置的不同状态，从而终端设备通过检测对应的标识即可以获悉候选小区对终端设备的无线资源控制配置的状态。
本公开的一些实施例中，终端设备接收原基站发送的自动切换配置信息和自动切换配置定时器信息，所述自动切换配置信息包括候选小区对所述终端设备的无线资源控制配置；所述终端设备启动自动切换配置定时器；若所述自动切换配置定时器超时，则所述终端设备确定所述候选小区对所述终端设备的无线资源控制配置失效。本公开的一些实施例通过自动切换配置定时器监控候选小区对终端设备的无线资源控制配置的状态，从而终端设备在自动切换过程中可以实时掌握候选小区对终端设备的无线资源控制配置的状态。
参见图3，图3是本公开的一些实施例提供的小区切换方法的流程图，如图3所示，包括以下步骤301-306。
步骤301、终端设备接收原基站发送的自动切换配置信息和自动切换配置定时器信息，所述自动切换配置信息包括候选小区对所述终端设备的无线 资源控制配置。
本公开的一些实施例中，若所述候选小区包括至少两个候选小区，则可以为所述至少两个候选小区中所有的候选小区设置一个共同的自动切换配置定时器信息，也可以为所述至少两个候选小区中每个小区分别设置一个自动切换配置定时器信息。
可选的，所述自动切换配置定时器信息包括所述候选小区中每个候选小区的自动切换配置定时器信息，或所述自动切换配置定时器信息包括用于所述候选小区中全部候选小区的自动切换配置定时器信息。
本公开的一些实施例可以为每个候选小区均配置自动切换配置定时器信息，例如，若上述候选小区包括至少两个候选小区，可以为至少两个候选小区中每个候选小区配置自动切换配置定时器信息，也即上述自动切换配置定时器信息包括至少两个候选小区中每个候选小区的自动切换配置定时器信息。
本公开的一些实施例中，通过为每个候选小区配置自动切换配置定时器信息，从而可以通过每个候选小区的自动切换配置定时器信息确定每个候选小区对应的自动切换配置定时器的时长，以更为准确的监控每个候选小区对终端设备的RRC配置的状态。
本公开的一些实施例也可以为全部候选小区配置一个共同的自动切换配置定时器信息，例如，若上述候选小区包括至少两个候选小区，可以为上述至少两个候选小区中全部的候选小区配置一个共同的自动切换配置定时器信息，也即上述自动切换配置定时器信息包括用于所述至少两个候选小区中全部候选小区的自动切换配置定时器信息。本公开的一些实施例通过为全部候选小区配置一个共同的自动切换配置定时器信息，便于终端设备控制统一监控全部候选小区对终端设备的RRC配置的状态。
可选的，所述自动切换配置定时器信息包括用于第一小区的第一自动切换配置定时器信息和/或用于第二小区的第二自动切换配置定时器信息，其中，所述第一小区为对所述终端设备配置有专用无线资源控制配置和公共无线资源控制配置的候选小区，所述第二小区为对所述终端设备未配置专用无线资源控制配置且配置有公共无线资源控制配置的候选小区。
本公开的一些实施例可以根据候选小区对终端设备的RRC配置的类型 为该候选小区配置对应的自动切换配置定时器信息。例如，对于对所述终端设备配置有专用无线资源控制配置和公共无线资源控制配置的候选小区配置第一自动切换配置定时器信息，对于对所述终端设备未配置专用无线资源控制配置且配置有公共无线资源控制配置的候选小区，配置第二自动切换配置定时器信息。
本公开的一些实施例可以根据每个类型的候选小区的自动切换配置定时器信息确定每个类型的候选小区对应的自动切换配置定时器的时长，以更为准确的监控每个类型的候选小区对终端设备的RRC配置的状态。
需要说明的是，本公开的一些实施例可以根据候选小区对终端设备的RRC配置的类型为每个候选小区均配置第一自动切换配置定时器信息和/或第二自动切换配置定时器信息，也可以为多个候选小区设置一个共同的用于第一小区的第一自动切换配置定时器信息，和/或，为多个候选小区设置一个共同的用于第二小区的第二自动切换配置定时器信息，本公开的一些实施例对此不做限定。
可选的，所述自动切换配置定时器信息包括用于专用无线资源控制配置的第三自动切换配置定时器信息和用于公共无线资源控制配置的第四自动切换配置定时器信息。
本公开的一些实施例还可以为不同的RRC配置设置不同的自动切换配置定时器信息，例如，可以为该候选小区分别配置用于专用无线资源控制配置的第三自动切换配置定时器信息和用于公共无线资源控制配置的第四自动切换配置定时器信息，并可以通过用于专用无线资源控制配置的第三自动切换配置定时器信息和用于公共无线资源控制配置的第四自动切换配置定时器信息分别控制对应的自动切换配置定时器，从而实现该候选小区不同类型的无线资源控制配置的状态的监控。
需要说明的是，本公开的一些实施例可以为每个候选小区的专用无线资源控制配置和公共无线资源控制配置均设置用于专用无线资源控制配置的第三自动切换配置定时器信息和用于公共无线资源控制配置的第四自动切换配置定时器信息，也可以为多个候选小区的专用无线资源控制配置设置一个共同的用于专用无线资源控制配置的第三自动切换配置定时器信息，为多个候 选小区的公共无线资源控制配置设置一个共同的用于公共无线资源控制配置的第三自动切换配置定时器信息，本公开的一些实施例对此不做限定。
上述自动切换配置定时器信息可以是由原基站配置的，也可以是候选基站配置的，并可以通过自动切换准备响应消息发送给原基站。可选的，所述自动切换配置定时器信息包括自动切换配置定时器的时长，或所述候选小区对所述终端设备的无线资源控制配置失效的时刻。上述候选小区对终端设备的无线资源控制配置失效的时刻即候选小区对终端设备的RRC配置失效的绝对时间。
具体的，自动切换配置定时器的时长可以根据上述自动切换配置定时器信息确定，例如，若上述自动切换配置定时器信息包括自动切换配置定时器的时长，则可以直接将上述自动切换配置定时器的时长作为自动切换配置定时器的时长。可选的，终端设备也可以根据原基站发送所述自动切换配置定时器的时长的起始发送时刻对自动切换配置定时器的时长进行修正，例如，将该自动切换配置定时器的时长减去原基站发送所述自动切换配置定时器的时长的起始发送时刻和自动切换配置定时器的启动时刻的差值作为修正后的自动切换配置定时器的时长，以控制自动切换配置定时器。
由于候选基站很难预估终端设备收到自动切换配置定时器信息的时间，候选基站可以将自动切换配置定时器的时长设置为候选小区保留RRC配置的时长，然后由原基站对候选小区保留RRC配置的时长进行修正，修正为终端设备所使用的保留RRC配置的时长，并作为修正后的自动切换配置定时器的时长，例如，原基站可以将候选小区保留RRC配置的时长减去从候选小区发送到原基站的自动切换准备响应消息的X2信令延时，作为终端设备所使用的自动切换配置定时器的时长。
可选的，若所述自动切换配置信息为所述候选小区对所述终端设备的无线资源控制配置失效的时刻，所述自动切换配置定时器的时长为所述候选小区对所述终端设备的无线资源控制配置失效的时刻与所述自动切换配置定时器的启动时刻的时间差值。
可选的，若所述自动切换配置定时器信息包括自动切换配置定时器的时长，所述自动切换配置定时器信息还包括所述原基站发送所述自动切换配置 定时器信息的起始发送时刻。
由于原基站将自动配置定时器信息发送给终端设备存在一定的时延，因此原基站可以将向终端设备发送所述自动切换配置定时器信息的起始发送时刻一并发送给终端设备，以便于终端设备根据所述自动切换配置定时器信息的起始发送时刻对自动切换配置定时器的时长进行修正。
可选的，在终端设备启动所述自动切换配置定时器之前，所述方法还包括：从所述自动切换配置定时器的时长中减去所述终端设备收到所述自动切换配置定时器信息的接收时刻和所述原基站发送所述自动切换配置定时器信息的起始发送时刻的差值，作为修正后的自动切换配置定时器的时长。
具体的，终端设备可以计算接收所述自动切换配置定时器信息的接收时刻和所述原基站发送所述自动切换配置定时器信息的起始发送时刻的差值，将自动切换配置定时器的时长减去该差值，作为修正后的自动切换配置定时器的时长，以控制自动切换配置定时器。

该步骤同上述步骤202，在此不再赘述。
步骤303、若所述自动切换配置定时器超时，则所述终端设备确定所述候选小区对所述终端设备的无线资源控制配置失效。
对于上述步骤302和步骤303，若候选小区包括至少两个候选小区，则可以为至少两个候选小区中每个候选小区配置自动切换配置定时器，并启动每个候选小区配置自动切换配置定时器，以通过每个候选小区对应的自动切换配置定时器监控每个候选小区对终端设备的RRC配置的状态，以提高对每个候选小区对终端设备的RRC配置的状态监控结果的准确性，从而可以降低因候选小区对终端设备的RRC配置失效导致切换失败的概率。

具体的，若候选小区的数量为一个，则上述目标候选小区即为该候选小区，若候选小区的数量为多个，则上述目标候选小区可以为多个候选小区中任意一个候选小区。
本公开的一些实施例中，终端设备可以在接收到基站发送的自动切换配置信息时启动各个候选小区的自动切换配置定时器，也可以在开始自动切换时(即在自动切换定时器超时时)启动各个候选小区的自动切换配置定时器，例如，若候选小区包括至少两个候选小区，则可以分别启动至少两个候选小区中每个候选小区的自动切换配置定时器。可选的，每个候选小区的自动切换配置定时器的时长可以根据其对应的自动切换配置定时器信息确定，这样可以使得对每个候选小区对终端设备的RRC配置的状态监控结果的准确性更高。
具体的，若某个候选小区的自动切换配置定时器超时，则确定该候选小区对终端设备的RRC配置失效，并可以将该候选小区对终端设备的RRC配置标识为失效，从而终端设备在选择目标小区接入时，可以根据该目标小区对终端设备的RRC配置的标识快速判断该目标小区对终端设备的RRC配置是否失效。
对于上述步骤302和步骤303，若候选小区包括至少两个候选小区，还可以根据至少两个候选小区中每个候选小区对终端设备的RRC配置的类型，将上述至少两个候选小区分为第一小区和第二小区两类，其中，所述第一小区为所述至少两个候选小区中对所述终端设备配置有专用无线资源控制配置和公共无线资源控制配置的候选小区，所述第二小区为所述至少两个候选小区中对所述终端设备未配置专用无线资源控制配置且配置有公共无线资源控制配置的候选小区。并分别为上述第一小区和第二小区配置自动切换配置定时器，以通过每个类型的候选小区对应的自动切换配置定时器监控每个类型的候选小区对终端设备的RRC配置的状态，以提高对每个类型的候选小区对终端设备的RRC配置的状态监控结果的准确性，从而可以降低因候选小区对 终端设备的RRC配置失效导致切换失败的概率。

本公开的一些实施例中，当终端设备从所述候选小区中选择第一目标小区接入时，可以通过检测第一目标小区的自动切换配置定时器是否超时来判断第一目标小区对所述终端设备的无线资源控制配置是否有效，例如，若检测到第一目标小区的自动切换配置定时器超时，则确定第一目标小区对所述 终端设备的无线资源控制配置失效，若检测到第一目标小区的自动切换配置定时器未超时，则确定第一目标小区对所述终端设备的无线资源控制配置有效。
本公开的一些实施例也可以通过检测第一目标小区对所述终端设备的无线资源控制配置的标识判断第一目标小区对所述终端设备的无线资源控制配置是否有效，例如，若检测到第一目标小区对所述终端设备的无线资源控制配置的标识指示第一目标小区对所述终端设备的无线资源控制配置失效，则确定第一目标小区对所述终端设备的无线资源控制配置失效，若检测到第一目标小区对所述终端设备的无线资源控制配置的标识指示第一目标小区对所述终端设备的无线资源控制配置有效，则确定第一目标小区对所述终端设备的无线资源控制配置有效。

本公开的一些实施例中，可以在终端设备发起切换之前将发起切换的次数n置为0，在终端设备每次发起切换时将终端设备发起切换的次数n加1，在终端设备接入目标小区成功后或是终端设备向所述原基站发送无线资源控制连接重建立请求后将终端设备发起切换的次数n重新置为0。
具体的，本公开的一些实施例在终端设备确定切换到所述第一目标小区失败之后，先判断终端设备连续发起切换的次数是否小于预设次数，其中， 预设次数可以根据实际情况进行合理设置。若所述终端设备连续发起切换的次数小于预设次数，则所述终端设备重新选择目标小区接入(即选择第二目标小区)，否则所述终端设备向所述原基站发送无线资源控制连接重建立请求，以发起无线资源控制连接重建立流程。

可选的，所述终端设备启动自动切换完成定时器，包括：若所述第一目标小区为所述终端设备配置有专用无线资源控制配置，则所述终端设备启动所述自动切换完成定时器。
本公开的一些实施例中，当目标小区为终端设备仅配置小区信息和公共RRC配置时，终端设备发起自动切换请求过程(跟RRC连接重建立的过程类似)完成切换，由于自动切换请求过程的每个消息都有特定的定时器进行控制，因此无需采用自动切换完成定时器控制切换完成的时间。而若目标小区为终端设备配置专用RRC配置，则终端设备向目标小区发送自动切换完成消息以进行接入，终端设备需要启动自动切换完成定时器以控制切换完成的时间。

具体的，上述公共RRC配置可以包括候选小区的系统广播块，以便于终端设备获得候选小区的系统信息，降低终端设备切换到候选小区的业务中断时间；上述专用RRC配置包含终端设备在候选小区中的安全参数配置、C-RNTI配置、专用RACH资源配置等，以便于终端设备获得在候选小区中的专用资源配置，加快终端设备完成到候选小区的切换速度。
步骤408、终端设备启动自动切换完成定时器。
实际应用中，在自动切换过早或选择了不合适的自动切换目标小区的情况下，会使终端设备长时间不能完成切换，导致业务中断时间过长。本公开的一些实施例可以通过自动切换完成定时器监控切换时长，以避免终端设备切换到目标小区时间过长，影响终端设备的正常通信。
具体的，上述自动切换完成定时器的时长可以从原基站给终端设备发送的自动切换完成定时器信息中获取。上述自动切换完成定时器信息可以由原基站设置，也可以由候选基站设置，并通过自动切换准备响应发送给原基站。原基站可以将自动切换完成定时器信息连同其他自动切换配置信息一起发送给终端设备，从而终端设备可以从自动切换完成定时器信息中获取自动切换完成定时器的时长。

需要说明的是，若终端设备向目标小区发起接入失败，允许终端设备重新选择该候选小区(也即当前切换失败的候选小区)作为目标小区，并应用该候选小区对终端设备的RRC配置发起接入。此外，当终端设备重新选择该候选小区(也即当前切换失败的候选小区)作为目标小区时，仍然需要判断该候选小区对终端设备的RRC配置是否有效，若有效，则应用该候选小区对终端设备的RRC配置发起接入；否则，终端设备不应用该候选小区对终端设备的RRC配置发起接入。
步骤411、若终端设备接入目标小区成功，则终端设备停止自动切换完成定时器。

具体的，在自动切换准备过程中，原基站可通过向候选基站发送自动切换准备请求消息，以请求一个或至少两个候选基站的一个或至少两个候选小区对终端设备进行RRC配置，候选小区对终端设备的RRC配置通过自动切换准备响应由候选基站发送给原基站。
步骤602、所述原基站向终端设备发送所述自动切换配置信息和自动切换配置定时器信息，以使所述终端设备根据所述自动切换配置信息和所述自动切换配置定时器信息进行自动切换。
上述自动切换配置定时器信息可以是由原基站配置的，也可以是候选基站配置的，并可以通过自动切换准备响应消息发送给原基站。可选的，上述自动切换配置定时器信息可以包括自动切换配置定时器的时长，也可以包括候选小区对终端设备的RRC配置失效的绝对时间(也即候选小区对终端设备的RRC配置失效的时刻)，从而终端设备可以根据自动切换配置定时器信息配置自动切换配置定时器。
具体的，原基站向终端设备发送所述自动切换配置信息和自动切换配置定时器信息，以使所述终端设备根据所述自动切换配置信息和所述自动切换配置定时器信息进行小区切换，例如，终端设备可以根据自动切换配置定时器信息启动自动切换配置定时器以监控候选小区对终端设备的RRC配置的状态，利于终端设备合理决策是否应用候选小区对终端设备的RRC配置接入该候选小区，例如，在候选小区对终端设备的无线资源控制配置有效时可以 应用该对终端设备的无线资源控制配置接入该候选小区，在候选小区对终端设备的无线资源控制配置失效时可以不应用该对终端设备的无线资源控制配置接入该候选小区，以减少切换失败的概率。
可选的，所述自动切换配置定时器信息包括自动切换配置定时器的时长或所述候选小区对所述终端设备的无线资源控制配置失效的时刻。
具体的，上述候选小区对终端设备的无线资源控制配置失效的时刻即候选小区对终端设备的RRC配置失效的绝对时间，例如，候选小区A对终端设备的无线资源控制配置失效的时刻为2017年7月3日08时30分30秒，或者，候选小区A对终端设备的无线资源控制配置失效的时刻为SFN为1023的时刻。
具体的，自动切换配置定时器的时长可以根据上述自动切换配置定时器信息确定，例如，若上述自动切换配置定时器信息包括自动切换配置定时器的时长，则可以直接将上述自动切换配置定时器的时长作为自动切换配置定时器的时长。可选的，终端设备也可以根据原基站发送所述自动切换配置定时器的时长的起始发送时刻和自动切换配置定时器的启动时刻对自动切换配置定时器的时长进行修正，例如，将该自动切换配置定时器的时长减去原基站发送所述自动切换配置定时器的时长的起始发送时刻和自动切换配置定时器的启动时刻的差值作为自动切换配置定时器的时长。
可选的，所述自动切换配置定时器信息为所述候选基站发送的信息。
具体的，在自动切换准备过程中，原基站可通过向候选基站发送自动切换准备请求消息，以请求一个或至少两个候选基站的一个或至少两个候选小区对终端设备进行RRC配置，候选小区对终端设备的RRC配置连同自动切换配置定时器信息一起通过自动切换准备响应由候选基站发送给原基站备。
可选的若所述自动切换配置定时器信息包括所述候选基站设置的自动切换配置定时器的时长，所述原基站向所述终端设备发送所述自动切换配置信息和自动切换配置定时器信息之前，所述方法还包括：所述原基站对所述候选基站设置的自动切换配置定时器的时长进行修正，得到修正后的自动切换配置定时器的时长；
所述原基站向所述终端设备发送所述自动切换配置信息和自动切换配置 定时器信息，包括：所述原基站向所述终端设备发送所述自动切换配置信息和所述修正后的自动切换配置定时器的时长。
实际应用中，由于候选基站很难预估终端设备收到自动切换配置定时器信息的时间，候选基站可以将自动切换配置定时器的时长设置为候选小区保留RRC配置的时长，然后由原基站对候选小区保留RRC配置的时长进行修正，修正为终端设备所使用的保留RRC配置的时长，例如，可以将候选小区保留RRC配置的时长减去原基站预估的从候选基站发到原基站的自动切换准备响应消息的X2信令延时，作为终端设备所使用的自动切换配置定时器的时长。
例如，候选基站设置的自动切换配置定时器的时长为5秒，并发送给原基站，原基站将该自动切换配置定时器的时长5秒减去候选基站发到原基站的自动切换准备响应消息的X2信令延时50毫秒，得到修正后的自动切换配置定时器的时长，即4950毫秒，并发送给终端设备。
本公开的一些实施例通过原基站对候选基站设置的自动切换配置定时器的时长进行修正后发送给终端设备，可以提高候选小区对终端设备的RRC配置的状态的监测结果的准确性。
可选的，若所述自动切换配置定时器信息包括自动切换配置定时器的时长，所述原基站向所述终端设备发送所述自动切换配置信息和自动切换配置定时器信息，包括：所述原基站向所述终端设备发送所述自动切换配置信息、所述自动切换配置定时器信息和所述原基站发送所述自动切换配置定时器信息的起始发送时刻，以使所述终端设备根据所述原基站发送所述自动切换配置定时器信息的起始发送时刻对所述自动切换配置定时器的时长进行修正。
实际应用中，由于LBT(Listen Before Talk，先听后说)机制的原因，终端设备的基站(也即原基站)通常难以预估终端设备何时收到自动切换配置定时器信息，因此，原基站可以将发送自动切换配置定时器的时长的起始发送时刻连同自动切换配置定时器的时长发送给终端设备，从而终端设备可以根据所述自动切换配置定时器信息的起始发送时刻确定原基站发送自动切换信息的时延，并从收到的自动切换配置定时器的时长中减掉该时延得到修正后的自动切换配置定时器的时长，通过修正后的自动切换配置定时器的时长 控制自动切换配置定时器，以提高候选小区对终端设备的RRC配置的状态的监测结果的准确性。
例如，候选基站设备的自动切换配置定时器的时长为5秒，原基站向终端设备发送自动切换配置定时器的时长的起始时刻为SFN为0的时刻，终端设备收到自动切换配置定时器信息并启动自动切换配置定时器的时刻为SFN为100的时刻，每个系统帧长度为10毫秒，则修正后的自动切换配置定时器的时长为4秒。

步骤705、若所述自动切换配置定时器超时，则终端设备确定候选小区对所述终端设备的无线资源控制配置失效。
本公开的一些实施例中，若自动切换配置定时器超时，则终端设备确定 候选小区对所述终端设备的无线资源控制配置失效，则可以不应用候选小区对终端设备的RRC配置发起接入，否则，则可以应用候选小区对终端设备的RRC配置发起接入。
