具体实施方式
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、完整地描述，显然，所描述的实施例是本发明一部分实施例，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，都属于本发明保护的范围。
位置服务(Location Services，LCS)业务是指移动通信系统通过特定的定位技术获取移动终端的地理位置信息(例如经纬度坐标)，提供给移动用户本人、通信系统或第三方定位客户端，并借助一定的电子地图信息的支持，为移动用户提供与其位置相关的呼叫或非呼叫类业务。
LCS业务涉及的网元主要包括UE、基站、核心网设备和定位中心。
其中，定位中心，可以是演进服务移动定位中心(Evolvoed Serving Mobile Location Centre，E-SMLC)、移动位置中心网关(Gateway Mobile Location Centre，GMLC)等实体。定位中心的主要功能是选择定位方法。对返回的位置估计计算最终结果和精度等，使得UE或除UE外的其他LCS实体可以获得UE的位置信息。
核心网设备，可以包括蜂窝物联网业务网关(CIoT Serving Gateway Node，C-SGN)、移动管理实体(Mobility Management Entity，MME)、业务网关(Serving Gateway，S-GW)、分组数据服务网关(Packet Data Serving Gateway，P-GW)等。
基站可以是全球移动通信(Global System for Mobile communication，GSM)系统或码分多址(Code Division Multiple Access，CDMA)系统中的基站(Base Transceiver Station，BTS)，宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统中的基站(NodeB)，LTE系统中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者未来5G网络中的基站设备、小基站设备等，本发明对此并不限定。
用户设备通常情况下也可称为终端设备。UE可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网(Core Network)设备进行通信，UE又可称为接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。UE可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol， SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备以及未来5G网络中的用户设备等。
图1示出了一种定位方法的示意性流程图。以下，简要介绍图1所示的定位方法。
S101a，UE向核心网设备发送位置服务请求(Location Service Request)消息。
S101b，(除UE外的)其他LCS实体向核心网设备发送位置服务请求消息。
S101c，核心网设备触发位置服务请求消息。
结合S101a，S101b，和S101c，位置服务请求消息可以来自UE，或者来自除UE外的其他LCS实体，或者是由核心网设备本身自己触发的。UE、其他LCS实体或者核心网设备可以通过位置服务请求消息，请求获取UE的位置信息。
S102，核心网设备向定位中心发送位置服务请求消息。
无论哪个网络节点触发位置服务请求消息，最后均由核心网设备向定位中心发送位置服务请求消息。
S103，定位中心向UE发送定位能力请求消息。
定位中心接收位置服务请求消息后，通过向UE发送定位能力请求消息，请求UE的定位能力。定位能力主要指UE的测量能力，具体地可以参照现有技术，为了简洁，此处不作具体描述。可选的，定位中心也可以不进行能力信息请求，UE自行进行上报。
S104，UE向定位中心发送定位能力上报消息。
UE响应定位中心的定位能力请求，向定位中心上报定位能力上报消息，告知UE的定位能力。
S105，UE向定位中心发送请求辅助数据消息。
UE将定位能力上报消息发送给定位中心后，UE可以向定位中心请求辅助数据。UE通过请求辅助数据消息，请求的信息可能包括以下信息：参考小区的信息，包括参考小区的物理小区标识(Physical Cell Identifier，PCI)、E-UTRAN小区全局标识符(E-UTRAN Cell Global Identifier，ECGI)、频点、 位置参考信号(positioning reference signal，PRS)配置等信息，选取的参考小区并不局限于服务小区；邻小区信息列表，包括每个邻小区的PCI、E-CGI、频点、PRS配置等信息。邻小区信息列表是根据预先对UE位置的估计而选取的一些利于测量的邻小区。
S106，定位中心向UE发送提供辅助数据消息。
定位中心向UE发送提供辅助数据消息，对UE进行测量配置。提供辅助数据消息中包括的信息可能包括以下信息：参考小区的信息，包括参考小区的PCI、E-UTRAN小区全局标识符(E-UTRAN Cell Global Identifier，ECGI)、频点、PRS配置等信息，选取的参考小区并不局限于服务小区；邻小区的信息，包括：邻小区信息列表，包括每个邻小区的PCI、E-CGI、频点、测量信号或者参考信号配置等信息。邻小区信息列表是根据预先对UE位置的估计而选取的一些利于测量的邻小区。
S107，定位中心向UE发送位置信息请求消息。
定位中心向UE发送位置信息请求消息，请求相关的测量结果。
S108，UE向定位中心发送提供位置信息消息。
UE在接收到位置信息请求消息后，在一段时间内通过提供位置信息消息将相关的测量结果发送给定位中心。
S109，定位中心根据提供位置信息消息计算定位结果。
定位中心根据UE的测量结果以及其他各方面输入，计算出UE的位置信息。
S110，定位中心向核心网设备发送定位结果(位置信息)。
S111a，核心网设备向UE发送定位结果。
如果是UE触发的位置服务请求，则核心网设备将定位结果发送至UE。
S111b，核心网设备向EPC LCS实体发送定位结果。
如果是其他LCS实体触发的位置服务请求，则核心网设备将定位结果发送至其他LCS。
现有技术的定位方式中，例如如图1所示的定位方式中，在UE覆盖情况较差时，UE仍需要根据定位中心的定位测量配置进行测量，并进行位置信息的上报。而在定位精度允许的情况下，UE的一些位置信息的上报可能不是必须的，也就是说，定位中心的定位测量配置可能对于此时的UE不合适，那么，就需要定位中心对UE进行合理的定位测量的配置。本发明提供 了一种传输信息的方法，能够使得定位中心根据UE的覆盖情况，对UE进行合理的定位测量的配置。下面，将对本发明提供的传输信息的方法进行阐述。
图2是根据本发明实施例的传输信息的方法的示意性流程图。
S210，定位中心获取覆盖指示信息。
以下，对覆盖指示信息进行详细描述。
覆盖指示信息可以指示UE的覆盖增强等级。覆盖增强等级的详细内容可以参照现有技术，此处不再详述。以下，为了方便描述，将以覆盖增强等级越高，UE的覆盖情况越差为例，详细描述本发明相关实施例。
另外，该覆盖指示信息可以指示UE处于差覆盖增强等级。当UE的覆盖增强等级差高于某一覆盖增强等级时，可以认为UE处于差覆盖增强等级。例如，覆盖增强等级分为3个等级，分别为0、1和2时，数字越大，表示UE的覆盖情况越差。在UE的覆盖增强等级大于或等于为1，即UE的覆盖增强等级为1或2时，则认为UE处于差覆盖增强等级。定位中心根据覆盖指示信息，可以确定UE的覆盖情况较差。
此外，该覆盖指示信息还可以指示UE请求减少测量小区的数量。在UE的覆盖情况较差时，可以通过覆盖指示信息，请求定位中心较少该UE测量小区的数量。
本发明实施例中，定位中心获取覆盖指示信息时可以采用方式一和方式二两种方式。下面，对方式一和方式二进行详细介绍。
方式一：
定位中心接收核心网设备发送的覆盖指示信息。换句话说，定位中心可以从核心网设备处获取覆盖指示信息。作为示例而非限定，核心网设备可以主动向定位中心发送覆盖指示信息。在一种实现方式中，核心网设备可以在向定位中心发送的位置服务请求消息中携带覆盖指示信息。位置服务请求消息也可以称为位置服务请求(Location Service Request)消息。作为示例而非限定，核心网设备也可以在定位中心请求覆盖指示信息后才发送覆盖指示信息。
其中，核心网设备向定位中心发送的覆盖指示信息，可以从基站处获取。在连接态时，基站可以根据传输数据情况判断UE覆盖情况，并根据UE的覆盖情况确定覆盖指示信息。例如，基站可以根据向UE发送数据的重复次 数、UE的响应时间等判断UE覆盖情况。一般地，基站向UE发送数据的重复次数越多、UE的响应时间越长，UE的覆盖情况越差。另外，UE也可以向基站隐式或显示地指示UE的覆盖增强等级。例如，UE可以在向基站发送的随机接入请求中显示地指示该覆盖指示信息。基站隐式或显示地指示UE的覆盖增强等级的具体方式可以参照现有技术，此处不再赘述。在基站确定UE的覆盖增强等级后，根据覆盖增强等级可以确定覆盖指示信息。
在基站确定覆盖指示信息后，作为一例，基站可以主动向核心网设备发送覆盖指示信息。具体地，基站可以在发送给该核心网设备的初始UE消息或UE上下文恢复请求消息中携带该覆盖指示信息。作为另一例，基站也可以在核心网设备请求覆盖指示信息后，才向核心网设备发送覆盖指示信息。具体地，核心网设备首先向基站发送覆盖请求消息，请求所述覆盖指示信息。基站接收到覆盖请求消息后，向核心网设备发送响应所述覆盖请求消息的覆盖请求响应消息，通过覆盖请求响应消息携带该覆盖指示信息。
具体来说，基站通过UE的随机接入过程获得了UE的覆盖等级信息，之后基站确定覆盖指示信息，并通过初始UE上下文或者其他上行S1AP消息发送给核心网设备，核心网设备在发送给定位中心的位置服务请求中携带该覆盖指示信息，使用定位中心作出相应配置。当UE处于连接态时，UE覆盖等级发生变化，基站获得UE变化的覆盖等级信息后，确定覆盖指示信息，并通过上行S1AP消息发送给核心网设备，具体消息可以是一条新的消息，如UE覆盖信息传输，或者现有的消息如UE能力信息指示(UE capability info indication)核心网设备收到后位置服务请求后，通过位置服务请求消息发送给定位中心，定位中心进行相关配置。
作为一例，当核心网设备收到定位服务请求或者位置服务请求后或者自己决定请求后，核心网设备向基站发送索取覆盖指示信息请求，基站在响应消息中携带覆盖指示消息。核心网设备收到后通过位置服务请求消息发送给定位中心。
基站也可以在UE覆盖等级发生变化后将覆盖指示消息发送给核心网设备，并由核心网设备转发给定位中心。
方式二：
定位中心接收UE发送的覆盖指示信息。换句话说，定位中心可以从UE处获取覆盖指示信息。
作为示例而非限定，UE可以在向定位中心发送的定位能力上报消息中携带覆盖指示信息。在该方案中，UE可以主动通过发送定位能力上报消息，上报覆盖指示信息。进一步地，UE也可以在定位中心请求覆指示信息时再上报。具体地，定位中心可以先向UE发送定位能力请求消息，请求覆盖指示信息。UE根据定位中心的请求，在上报的定位能力上报消息中携带该覆盖指示信息。
作为示例而非限定，UE可以在向定位中心发送的请求辅助数据消息中携带覆盖指示信息。
结合方式一和方式二，可以看出，本发明实施例中，UE和核心网设备可以通过现有协议中的信令传输覆盖指示信息。
在方式一和方式二中，进一步地，当处于连接态时，如果UE的覆盖增强等级发生变化，UE可以通过向定位中心发送变更覆盖指示信息，指示变化后的覆盖增强等级。或者，在基站发现UE的覆盖增强等级发生变化时，基站可以通过核心网络设备的转发，向定位中心发送变更覆盖指示信息，指示变化后的覆盖增强等级。基站或UE发送变更覆盖指示信息时，可以通过现有S1消息发送，本发明实施例对此不作特殊限定。定位中心接收到变更覆盖指示信息后，可以根据变化后的覆盖增强等级，在接收到位置服务请求后，对UE进行配置。
S220，定位中心向UE发送定位测量配置信息。定位测量配置信息用于对UE进行定位测量配置。具体地，在定位中心接收到覆盖指示信息后，可以根据覆盖指示信息确定定位测量配置信息。
作为示例而非限定，定位中心可以根据覆盖指示信息，确定UE测量的小区数量。
举例来说，定位中心可以根据不同的覆盖增强等级，限定测量小区的最大数目，或者设置测量小区数量的上线限。当定位中心通过覆盖指示信息确定UE的覆盖增强等级时，可以根据覆盖增强等级配置UE测量的小区数量。例如，当UE的覆盖增强等级为0时，可以配置UE测量的小区数量为8～24个；当UE的覆盖增强等级为1时，可以配置UE测量的小区数量为8～15个；当UE的覆盖增强等级为2时，可以配置UE测量的小区数量为8～11个。
举例来说，定位中心通过覆盖指示信息确定UE处于差覆盖增强等级或者UE请求较少测量小区的数量时，可以在定位精度允许的情况下，配置 UE测量较少的小区。例如，定位中心可以将覆盖增强等级为2时UE需要测量的小区数量配置为UE此次需要测量的小区的数量。应理解，此处仅为示例性说明，本发明实施例对此不作具体限定。
作为示例而非限定，定位中心可以根据覆盖指示信息，确定UE响应位置信息请求消息的响应时间。以下，为了描述方便简洁，简称UE响应位置信息请求消息的响应时间为响应时间。
具体地，定位中心可以根据不同的覆盖等级，设置合适的响应时间。覆盖等级越高，响应时间越长。在UE处于差覆盖增强等级时，或者，在UE请求减少测量小区的数量时，定位中心可以给UE配置较长的响应时间，保证UE能够完成本次测量。
作为示例而非限定，定位中心可以根据覆盖指示信息，确定UE测量的频点信息。
具体地，定位中心在UE覆盖情况较差时，可以配置UE只测量同频小区。定位中心通过定位测量配置信息，配置UE测量的小区的频点。
作为示例而非限定，定位中心可以通过现有协议中的信令传输定位测量配置信息。具体地，定位中心可以通过向UE发送提供辅助数据消息，向UE发送定位测量配置信息。也就是说，提供辅助数据消息可以携带定位测量配置信息。这样，UE在接收到提供辅助数据消息时，可以获得定位测量配置信息。
可选地，该方法还可以包括：
S230，定位中心向UE发送位置信息请求消息，请求UE发送测量报告。
具体地，UE在接收到定位测量配置信息后，根据定位测量配置信息进行测量。例如，UE可以只对定位中心配置的同频小区测量，或UE可以只测量定位中心要求的数量的小区。
S240，UE向定位中心发送提供位置信息消息。
具体地，UE根据定位测量配置信息，在完成小区测量后，在定位中心配置的响应时间内向定位中心发送测量报告。
S250，定位中心根据提供位置信息消息确定定位结果。
定位中心根据UE的测量报告确定UE的位置信息，即定位结果。
S260，定位中心向核心网设备发送定位结果。
核心网设备接收到定位结果后，将定位结果发送至请求位置服务的网 元。
本发明实施例的传输信息的方法，定位中心可以根据UE的覆盖情况，或根据UE的减少测量小区的数量的请求，对UE进行更灵活的测量配置。例如，一方面，在覆盖增强等级较高或处于差覆盖增强等级的情况下UE进行定位测量时，定位中心可以通过减少UE测量小区的数量来减少UE上报的测量报告，从而能够降低UE的功耗，以及降低UE上报测量报告的时延。另一方面，定位中心通过配置合适的响应时间，或者配置UE测量同频小区，可以保证UE在覆盖情况较差时，完成本次定位测量，从而不需要下一次测量触发，进而能够提高效率，较少信令开销，进一步降低功耗。
本发明实施例中，UE或者基站可以向定位中心提供一个小区列表，当定位中心收到后，就可以根据接收到的小区列表进行测量配置，这样定位中心不需要自己或者人工维护一个小区列表来配置测量的的小区范围，提供的小区列表可以包括服务小区或者邻小区的小区信息，也可以包括配置信息如参考符号的配置信息等，这样通过提供的小区列表，也能够较为准确的进行测量配置，而不需要配置一些较远的或者对定位结果小的小区。提供小区列表的的消息可以使用现有消息，如OTDOA/UTDOA信息响应或更新消息(OTDOA/UTDOA INFORMATION RESPONSE)(OTDOA/UTDOA INFORMATION UPDATE)，或者其他消息，也可以是新的消息，具体不限制。

本发明实施例的传输信息的方法，UE可以采用UP方案重建RRC连接，也可以采用CP方案重建RRC连接。UE采用UP方案重建RRC连接可以参照现有技术。下面，将介绍UE采用CP方案重建RRC连接的方案。
图14示出了一种无线资源控制RRC连接的方法。
S1410，UE向目标基站发送建立指示信息。建立指示信息用于向目标基站指示UE采用控制面CP方案和用户面UP方案中的其中一种方案建立RRC连接。
UE与目标基站重建RRC连接，或者恢复RRC连接时，可能采用CP方案，也可能采用UP方案。但是目标基站不能够确定UE采用何种方案重建(包括重建和恢复)RRC连接。而本发明实施例的RRC连接的方法，UE可以通过向目标基站指示，使得目标基站能够确定UE采用何种方案建立RRC连接。从而，目标基站能够确定获取UE上下文的操作流程，即采用与CP相关的操作流程还是采用与UP相关的操作流程。进而，目标基站可以通 过相应流程获取UE上下文，与UE建立RRC连接。
本发明实施例中，UE向目标基站发送建立指示信息，可以通过RRC连接重建立请求消息发送，也可以通过RRC连接恢复请求消息，或者还可以通过RRC连接建立请求消息发送。也就是说，RRC连接重建立请求消息、RRC连接恢复请求消息、RRC连接建立请求消息均可以携带建立指示信息。
S1420，目标基站向源基站发送RLF指示消息或重新取回UE上下文请求消息(Retrieve UE context request)。RLF指示消息或重新取回UE上下文请求消息包括建立指示信息。应理解，RLF指示消息或重新取回UE上下文请求消息用于请求UE的上下文。
S1430，源基站根据RLF指示消息，向目标基站发送切换请求消息。或，源基站根据重新取回UE上下文请求消息，向目标基站发送重新取回UE上下文响应消息。
具体地，源基站根据目标基站发送的RLF指示消息或重新取回UE上下文响应消息中的建立指示信息，可以确定UE采用CP方案还是UP方案建立RRC连接。源基站确定UE采用CP方案或UP方案建立RRC连接后，源基站基于相应的方案对UE进行识别和校验。如果源基站能够识别该UE，并且校验成功，则通过向目标基站发送切换请求消息或重新取回UE上下文响应消息，向UE发送UE的上下文。
可选地，RRC连接重建立请求消息、RRC连接恢复请求消息或RRC连接建立请求消息还可以包括用于标识或校验该UE的第一标识信息。
作为示例而非限定，第一标识信息可以包括以下中的至少一种：hash S-TMSI、截断的S-TMSI、M-TMSI、用户专用标识、基站ID，截断的基站ID，ECGI、eNB UE S1AP ID。其中，hash S-TMSI、截断的S-TMSI和M-TMSI均是基于S-TMSI得到的。hash S-TMSI和截断的S-TMSI是UE基于预设算法生成的，M-TMSI为S-TMSI的后32位。用户专用标识为源基站分配的用于寻址保存上下文的用户标识。
另外，第一标识信息、RRC连接重建立请求消息或RRC连接恢复请求消息还可以包括小区无线网络临时标识(Cell Radio Network Temporary Identifier，C-RNTI)、PCI等参数。
在本发明实施例中，UE在向目标基站发送用户专用标识前，首先需要获取该用户专用标识。下面，结合图15，对UE获取用户专用标识的方法进 行详细描述。
S1510，UE与目标基站进行随机接入信道(Random Access Channel，RACH)流程。
具体地，RACH流程包括UE向目标基站发送随机接入请求，目标基站接收随机接入请求后向UE回复随机接入响应。更具体地可以参照现有技术，为了简洁，此处不再详述。
S1520，UE与源基站建立RRC连接。
这里的RRC连接可以是RRC连接建立流程，也可以是RRC连接重建立流程，或者RRC连接恢复流程，本发明实施例对此不作限定。相应地流程可以参照现有技术，为了简洁，此处不再详述
S1530，源基站向核心网设备发送所述用户专用标识。以下，为了描述方便，以核心网设备为MME为例进行说明。
用户专用标识可以是源基站随机产生的一段数码，也可以是现有技术中的相关参数，如eNB UE S1AP标识等标识，或一些标识的截断等。应理解，源基站会保存该用户专用标识。
源基站向MME发送所述用户专用标识时，可以使用采用初始UE消息，上下NAS传输消息，UE上下文恢复请求消息等进行发送。
S1540，MME接收到该用户专用标识后，可以将该用户专用标识发送给UE。
MME向UE发送该用户专用标识时，可以通过下行的一条NAS消息发送。此NAS消息可以是现有协议中的信令，如下行NAS传输，本发明实施例对此不做限定。具体的由MME发送给基站，在通过基站发送给UE的下行直传消息承载携带该UEID的NAS消息。
S1550，当UE发生移动性时，UE向目标基站发送该用户专用标识。
UE接收到该用户专用标识(MME在之前连接中发送的)后，进行保存。UE可以通过RRC连接重建立请求消息、RRC连接恢复请求消息、RRC连接建立请求消息等向目标基站发送该用户专用标识。RRC连接重建立请求消息、RRC连接恢复请求消息、RRC连接建立请求消息中还可以包括C-RNTI，PCI等标识。
在上述流程中，源基站分配的用户专用标识由MME通过NAS消息向UE发送，避免了直接暴漏在空口可能被截获篡改的问题。
可选地，源基站在对UE进行识别或校验时，可以采用第一标识信息对UE进行识别或校验。目标基站接收到UE发送的第一标识信息后，将其转发给源基站，源基站进行校验，即比对源基站保存的标识信息和目标基站发送的UE的相关标识信息是否一致，一致即校验成功，并把该UE的相关上下文发送给目标基站。
作为实例而非限定，源基站可以采用hash S-TMSI、截断的S-TMSI或M-TMSI对UE进行识别或校验。源基站根据存储的hash S-TMSI、截断的S-TMSI或M-TMS和接收到的对应的hash S-TMSI、截断的S-TMSI或M-TMSI、或基站ID、或截断的基站ID等对UE进行识别或校验。
其中，源基站存储的hash S-TMSI和截断的S-TMSI是源基站基于与UE约定或者协议规定的预设算法生成的。源基站获取S-TMSI的方式可以有两种，一是方式是，源基站从UE出获取S-TMSI。例如，源基站可以通过UE发送的发送RRC连接建立请求消息获取S-TMSI。也就是说，RRC连接建立请求消息可以携带所述S-TMSI。另一种方式是，源基站从MME处获取S-TMSI。具体地，如果UE没有在发送RRC连接建立请求消息时向源基站发送S-TMSI，则MME可以在后续的流程中通过下行S1-AP信令发送S-TMSI给源基站。S1-AP信令可以是下行NAS信息传输，还可以是UE初始上下文建立请求等，本发明实施例对此不作特殊限定。另外，如果MME重新分配了S-TMSI给UE，例如TAU等过程，则UE可以通过一条上行的RRC消息将更新的S-TMSI发送给源基站，或者MME通过一条下行的S1消息将更新的S-TMSI发送给源基站。本发明实施例对此处的上行的RRC消息和下行的S1消息不作特殊限定。
作为示例而非限定，源基站可以采用用户专用标识对UE进行识别或校验。源基站根据存储的用户专用标识和接收到的用户专用标识，对UE进行识别或校验。具体的，目标基站在接收到第一条带有相关标识和用户专用标识的消息，如RRC重建立请求消息后，又接收到同样带有相关标识的信息时，则认为这是假UE发送的，丢弃该消息。进而，能够确保源基站对UE的识别和校验的准确性。
源基站在对UE进行识别或校验成功，证明此UE是之前在源基站连接的UE，则源基站将UE的上下文发送给目标基站。
在目标基站获取UE上下文后，可选地，图14所示的方法还可以包括：
S1440，目标基站根据RRC连接重建立请求消息向UE发送RRC连接重建立消息，或
目标基站根据RRC连接恢复请求消息向UE发送RRC连接恢复消息；
S1450，UE根据RRC连接重建立消息向目标基站发送RRC连接建立完成消息，或
UE根据RRC连接恢复消息向目标基站发送RRRC连接恢复完成消息。
至此，RRC连接重建立或RRRC连接恢复完成。
可选地，该方法还可以包括：UE接收偏置指示信息，偏置指示信息指示小区信号质量偏置量。小区信号质量偏置量用于UE触发无线链路失败或连接态小区重选。具体的，如果也就是当服务小区低于阈值，而相邻小区信号质量比当前服务小区高于该小区信号质量偏置量时，UE执行连接态小区重选或者触发RLF。UE还可以接收阈值信息，阈值信息用于指示指示阈值，当服务小区低于指示阈值时，而相邻小区信号质量比当前服务小区高于该小区信号质量偏置量时，UE执行连接态小区重选或者触发RLF。
如服务小区信号质量低于的阈值，如服务小区比邻小区信号质量高于的偏置量。具体地，该偏置指示信息可以通过目标基站发送的RRC连接重建立消息携带，也可以通过源基站发送的RRC连接建立消息携带。另外，该偏置指示信息也可以通过其他下行RRC消息携带，如RRC连接重配置消息，RRC连接释放消息等，本发明实施例对此不作特殊限定。
