应当理解，尽管在本公开可能采用术语第一、第二等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本公开范围的情况下，第一参数也可以被称为第二参数，类似地，第二参数也可以被称为第一参数。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
需要说明的是，本申请所涉及的信息(包括但不限于用户设备信息、用户个人信息等)、 数据(包括但不限于用于分析的数据、存储的数据、展示的数据等)以及信号，均为经用户授权或者经过各方充分授权的，且相关数据的收集、使用和处理需要遵守相关国家和地区的相关法律法规和标准。
请参考图1，其示出了本申请一个实施例提供的系统架构的示意图。该系统架构可以包括：终端设备10和网络设备20。
终端设备10的数量通常为多个，每一个网络设备20所管理的小区内可以分布一个或多个终端设备10。终端设备10可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备，以及各种形式的用户设备(User Equipment，UE)，移动台(Mobile Station，MS)等等。为方便描述，本申请实施例中，上面提到的设备统称为终端设备。
网络设备00与终端设备10之间可以通过空口建立连接，从而通过该连接进行通信，包括信令和数据的交互。
网络设备20是一种部署在接入网中用以为终端设备10提供无线通信功能的装置。网络设备20可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备网络设备功能的设备的名称可能会有所不同，例如在5G NR系统中，称为gNodeB或者gNB。随着通信技术的演进，“基站”这一名称可能会变化。为方便描述，本申请实施例中，上述为终端设备10提供无线通信功能的装置统称为网络设备。网络设备10的数量可以有多个，两个邻近的网络设备10之间也可以通过有线或者无线的方式进行通信。终端设备20可以在不同的网络设备10之间进行切换，也即与不同的网络设备10建立连接。
本公开实施例中的“5G NR系统”也可以称为5G系统或者NR系统，但本领域技术人员可以理解其含义。本公开实施例描述的技术方案可以适用于5G NR系统，也可以适用于5G NR系统后续的演进系统。
以第五代移动通信技术为例，在NR早期部署时，完整的NR覆盖很难获取，典型的网络覆盖是广域的长期演进(Long Term Evolution，LTE)覆盖和NR的孤岛覆盖模式。大量的LTE部署在6GHz以下，可用于5G的6GHz以下频谱很少。为了保护移动运营商前期在LTE投资，提出了LTE和NR之间紧密的交互工作(Tight Interworking)的模式。以长期演进-新空口双链接(LTE-NR Dual Connectivity，EN-DC)为例，图2示出了EN-DC网络架构的示意图。其中LTE作为MN(Master Node，主节点)，NR作为SN(Secondary Node，辅节点)。MN主要用于实现RRC控制功能和通向CN(Core Network，核心网)的控制面，SN用于配置辅助信令，例如第三无线信令承载(Signaling Radio Bearer 3，SRB3)，主要提供数据传输功能。
MN的主小区称为主小区(Primary Cell，PCell)，MN的辅小区称为辅小区(Secondary Cell，SCell)，与MN相关的所有小区均属于主小区组(Master Cell Group，MCG)。SN的主小区称为主辅小区(Primary Secondary Cell，PSCell)，SN的辅小区称为辅小区(Secondary Cell，SCell)，与SN相关的所有小区均属于辅小区组(Secondary Cell Group，SCG)。图3示出了MCG和SCG结构的示意图。
在R17(Release17，第17期)中引入了对于BFD(Bidirectional Forwarding Detection，双向转发检测)/RLM(Radio Link Monitoring，无线链路监测)的放松机制。即对于满足放松准则(低移动性)的终端设备，将进行BFD/RLM放松机制。同理，对于RLF(Radio Link Failure，无线链路失败)以及RRM(Radio Resource Management，无线资源管理)也会针对低移动性或者禁止的用户进行RLF测量放松或者RRM测量放松。
低移动放松准则可以通过协议约定，将低移动性放松准则涉及到的评估参数通过测量触发事件的方式下发。低移动性评估的评估参数包括：T SearchDeltaP和S SearchDeltaP。静止性评估的评估参数包括T SearchDeltaP’和S SearchDeltaP’。其中，S SearchDeltaP和S SearchDeltaP’可以相同也可以不同。低移动性评估和静止性评估的判断标准(metric)为参考信号的L3(Layer3，层三)-RSRP (Reference signal received power，参考信号接收功率)。
在R16中，针对非连接态终端设备引入了RRM测量放松，其中一个规则为低移动性规则。
低移动性评估：在一定时间内(T SearchDeltaP)，若参考信号接收质量与UE当前的RSRP的差值小于某预设门限值(S SearchDeltaP)，即代表信号变化幅度不大，则可认为当前UE处于静止或低移动性状态。值得注意的是，该判决仅在参考信号接收质量下降时才需要进行考虑，具体判决条件为：(S rxlevRef-S rxlev)<S SearchDeltaP。其中，S rxlev＝当前服务小区的S rxlev，单位为dB；S rxlevRef＝当前服务小区的S rxlev参考值(基准值)，单位为dB。
相关技术中，基准值根据如下方式进行设置：
(1)UE选择或重选了一个新小区；
(2)(S rxlev-S rxlevRef>0)；
(3)在T SearchDeltaP内没有满足上述的判决条件；
在满足上述任一条件时，UE将S rxlevRef设为当前的服务小区的S rxlev。
请参考图4，其示出了本申请一个实施例提供的测量放松方法的流程图，该方法可以应用于图1所示的系统架构的终端设备中。该方法包括如下步骤。
步骤210：在处于RRC连接态的情况下，将基准值设置为当前测量值，基准值用于低移动性评估和/或静止性评估，当前测量值包括测量得到的参考信号的信号强度。
在终端设备处于RRC连接态时，终端设备将当前测量得到的参考信号的信号强度设置为低移动性评估或静止性评估的基准值。当然评估基准值还可以有其他的设置条件。类似于非连接态，比如当前测量值大于基准值；或者在限定时间内没有满足上述的判决条件；也会导致终端设备将当前测量得到的参考信号的信号强度(也即当前测量值)设置为低移动性评估或静止性评估的基准值。
在处于RRC连接态的情况下，将第一基准值设置为当前测量值，第一基准值用于低移动性评估。在处于RRC连接态的情况下，将第二基准值设置为当前测量值，第二基准值用于静止性评估。示例性的，第一基准值和第二基准值相同。或，第一基准值和第二基准值不同。
当前测量值是指终端设备最近一次测量得到的参考信号的信号强度。
信号强度包括Lay3-RSRP、Lay3-RSRQ(Reference Signal Received Quality，参考信号接收质量)、参考信号SINR(Signal to Interference plus Noise Ratio，信干噪比)中的至少一种。其中，对于RSRP其单位为dBm；对于RSRQ和RS-SINR其单位为dB(Is expressed in dBm in case of RSRP,or in dB in case of RSRQ and RS-SINR)。
基准值用于进行低移动性评估或静止性评估。终端设备计算测量得到的参考信号的信号强度与基准值的差值，将差值与预设门限值作比较，以确定终端设备是否处于低移动性状态或静止性状态。
综上所述，本实施例提供的方法，针对处于RRC连接态的终端设备，将当前测量得到的参考信号的信号强度，设置为基准值，以便终端设备使用该基准值进行低移动性评估/静止性评估。提供了一种在终端设备处于RRC连接态时，设置低移动性评估/静止性评估的基准值的方法。

目标接入网设备可以是终端设备所要切换/添加/修改的主辅小区(辅节点)对应的接入网设备。
例如，源接入网设备向目标接入网设备发送切换请求，切换请求包括能力信息，切换请求用于请求将终端设备从源接入网设备切换至目标接入网设备。
源接入网设备向目标接入网设备发送辅节点添加请求，辅节点添加请求包括能力信息，辅节点添加请求用于请求为终端设备添加辅节点。
源接入网设备向目标接入网设备发送辅节点修改请求，辅节点修改请求包括能力信息，辅节点修改请求用于请求为终端设备修改辅节点。示例性的，辅节点修改请求用于请求修改终端设备当前接入的辅节点的相关信息(例如，配置信息)。
源接入网设备向目标接入网设备发送辅节点切换请求，辅节点切换请求包括终端设备的能力信息，辅节点切换请求用于请求为终端设备切换辅节点。
切换请求还包括测量放松参数，或，辅节点添加请求还包括测量放松参数，或，辅节点修改请求还包括测量放松参数，或，辅节点切换请求还包括测量放松参数。测量放松参数用于目标接入网设备/目标小区做配置参考。
测量放松参数是源接入网设备为终端设备配置的，测量放松参数包括RRM测量放松、 RLM测量放松、BFD测量放松中的至少一种测量放松的参数。

终端设备在未接收到携带有测量放松参数的RRC连接重配消息的情况下，不启用低移动性评估和/或静止性评估。
步骤304：在终端设备处于RRC连接态的情况下，向终端设备发送RRC连接重配消息，RRC连接重配消息用于触发终端设备将基准值设置为当前测量值。
示例性的，若源接入网设备需要启用终端设备的低移动性评估和/或静止性评估，则向终端设备发送RRC连接重配消息，RRC连接重配消息中携带有测量放松参数的。终端在接收到RRC连接重配消息后，将基准值设置为当前测量值。
基站在RRC连接重配消息中携带RRM/RLM/BFD测量放松的测量放松参数；若终端设备收到RRC连接重配消息，则在切换到目标基站/目标小区时，或者在接入到新的Pscell时，将基准值设置为当前测量值，用于低移动性评估。此时即成功切换或成功接入到新的Pscell。对于终端而言，其可以判决媒体接入控制(Medium Access Control，MAC)的随机接入过程是否完成。其中，Pcell切换目标小区/切换目标接入网设备；Pscell切换即为SN change。若终端没有收到RRC连接重配消息，或者切换或者接入到新的Psell失败无需启动低移动性评估。
作为一种实施例：终端判决切换主节点切换成功：即MCG的MAC节点成功完成了往目标小区或者基站的随机接入过程。此时，RRC重配置消息中MCG的spCellConfig携带了同步重配置，终端在接收到同步重配置指示后将发起随机接入过程。即After MAC of an MCG successfully completes a Random Access procedure after applying an reconfigurationWithSync in spCellConfig of an MCG，则终端将基准值设置为当前测量值。
即，终端设备在接收到RRC连接重配消息，且从源接入网设备切换到目标接入网设备的情况下，将基准值设置为当前测量值；或，在接收到RRC连接重配消息，且切换到目标主小区的情况下，将基准值设置为当前测量值；或，在接收到RRC连接重配消息，且切换到第一目标主辅小区的情况下，将基准值设置为当前测量值；或，在接收到RRC连接重配消息，且接入到第二目标主辅小区的情况下，将基准值设置为当前测量值。
可选地，在接收到RRC连接重配消息，且接入到第二目标主辅小区的情况下，将基准值设置为当前测量值包括：在接收到RRC连接重配消息，且修改第二目标主辅小区的情况下，将基准值设置为当前测量值。
作为一种实施例：终端判决切换到第一目标主辅小区成功：即SCG的MAC节点成功完成了往目标小区或者基站的随机接入过程。此时，RRC重配置消息中SCG的spCellConfig携带了同步重配置，终端在接收到同步重配置指示后将发起随机接入过程。即After MAC of an SCG successfully completes a Random Access procedure after applying an  reconfigurationWithSync in spCellConfig of an SCG，则终端将基准值设置为当前测量值。
综上所述，本实施例提供的方法，终端设备可以向源接入网设备上报是否支持测量放松的能力信息，源接入网设备可以将该能力信息转发给其他接入网设备，以便其他接入网设备做配置参考。源接入网设备可以在RRC连接重配消息中携带测量评估参数，当终端设备接收到该RRC连接重配消息并完成小区切换时，将基准值设置为当前测量值；若终端设备未接收到该RRC连接重配消息，则不启用低移动性评估和静止性评估。
需要说明的是，上述实施例中将低移动性评估和静止性评估分为两个实施例来进行阐述，但是本领域技术人员可以将上述两个实施例进行结合，实现成为同时支持低移动性评估和/或静止性评估的新实施例，对此不加以赘述。
