具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。
应理解，本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统、新无线(New Radio，NR)或未来的5G系统等。
特别地，本申请实施例的技术方案可以应用于各种基于非正交多址接入技术的通信系统，例如稀疏码多址接入(Sparse Code Multiple Access，SCMA)系统、低密度签名(Low Density Signature，LDS)系统等，当然SCMA系统和LDS系统在通信领域也可以被称为其他名称；进一步地，本申请实施例的技术方案可以应用于采用非正交多址接入技术的多载波传输系统，例如采用非正交多址接入技术正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)、滤波器组多载波(Filter Bank Multi-Carrier，FBMC)、通用频分复用(Generalized Frequency Division Multiplexing，GFDM)、滤波正交频分复用(Filtered-OFDM，F-OFDM)系统等。
本申请实施例中的终端设备可以指用户设备(User Equipment，UE)、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。接入终端可以是蜂窝电话、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，未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network，PLMN)中的终端设备等，本申请实施例并不限定。
本申请实施例中的网络设备可以是用于与终端设备通信的设备，该网络设备可以是GSM或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional NodeB，eNB或eNodeB)，还可以是云无线接入网络(Cloud Radio Access Network，CRAN)场景下的无线控制器，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络设备或者未来演进的PLMN网络中的网络设备等，本申请实施例并不限定。
图1是本申请实施例一个应用场景的示意图。图1中的通信系统可以包括终端设备10和网络设备20。网络设备20用于为终端设备10提供通信服务并接入核心网，终端设备10通过搜索网络设备20发送的同步信号、广播信号等而接入网络，从而进行与网络的通信。图1中所示出的箭头可以表示通过终端设备10与网络设备20之间的蜂窝链路进行的上/下行传输。
为了方便理解本申请实施例，首先结合图2对演进分组系统(Evolved Packet System，EPS)承载业务架构中的一些要素进行简要说明。如图2所示，该网络架构主要包括演进型通用移动通讯系统陆地无线接入网(Evolved-Universal Mobile Telecommunication System Terrestrial Radio Access Network，E-UTRAN)和分组核心网(Evolved Packet Core，EPC)，其中，EPC包括服务网关(Serving Gateway，S-GW)和分组数据网关(Packet Data Network Gateway，P-GW)。在EPS承载的业务架构体系中，端到端的业务可以分解为EPS承载和外部承载两部分。其中，一个演进的无线接入承载(Evolved Radio Access Bearer，E-RAB)用于在UE和演进的EPC间传输一个EPS承载的分组包，E-RAB和EPS承载间是一一对应关系。一个无线承载用于在UE和eNodeB间传输一个E-RAB承载的分组包，无线承载和E-RAB/EPS承载间存在一一对应关系。一个S1承载用于在eNodeB和一个S-GW间传输一个E-RAB承载的分组包。一个S5/S8承载用于在S-GW和P-GW间传输一个EPS承载的分组包，外部承载用于传输EPC与对等实体之间的信息。
在LTE系统中，UE的RRC状态主要包括RRC空闲态和RRC连接态。 其中，RRC空闲态：存在S5/S8承载，没有无线承载和S1承载，核心网侧保留UE上下文，eNodeB和UE不保留彼此上下文，终端保留时间提前(Time advance，TA)内唯一的标识(通常为临时移动用户标识(Temporary Mobile Subscriber Identity，TMSI))。处于RRC空闲态的UE不可以有与网络交互数据，非接入层(Non-access stratum，NAS)配置的非连续接收(Discontinuous Reception，DRX)过程，系统信息广播和寻呼、邻小区测量，小区重选的移动性，没有测量报告的上报等行为。RRC连接态：存在S5/S8承载、S1承载和无线承载，核心网、eNodeB和UE都保留相应上下文，eNodeB分配接入层(access stratum，AS)标识(通常为小区无线网络临时标识(Cell Radio Network Temporary Identifier，C-RNTI))。处于RRC连接态的UE可以和网络交互数据，可能存在AS配置的DRX，切换的移动性，上报信道测量给网络侧等行为。
在5G系统中，引入了第三种状态，即RRC非激活态。RRC非激活态：存在S5/S8承载、S1承载以及部分无线承载，核心网、eNodeB和UE都保留相应上下文，eNodeB分配接入层AS标识(通常为恢复(Resume)标识(identification，ID))。处于RRC非激活态的UE具有小区重选的移动性，没有测量上报，可以进行小数据发送和接收，可能存在AS配置的DRX。
图3示出了本申请实施例的无线通信的方法100的示意性框图。如图3所示，该方法100包括以下部分或全部内容：
S110，终端设备获取用于在非激活态下执行小区选择和重选的移动性控制参数。
应理解，本申请实施例中涉及的非激活态也就是上述RRC激活态。终端设备可以获取用于在非激活态下执行小区选择和重选的移动性控制参数，例如，可以通过RRC专用信令或者系统广播消息。该移动性控制参数可以包括以下参数中的至少一种参数：终端设备的移动状态的判决参数、终端设备的移动状态的各个参数的缩放参数和基于频率的小区重选优先级参数。所谓终端设备的移动状态可以定义为规定时间的小区重选次数，可以包括高速移动状态、中速移动状态和正常移动状态。该终端设备的移动状态的判决参数例如可以是用于指示终端设备进入中或高速移动状态判决时的时间窗T CRmax，或者是用于指示高速移动状态判决的小区重选次数门限N CR_H，或者是用于指示中速移动状态判决的小区重选次数门限N CR_M，还可以是用于指 示终端设备离开中/高速移动状态判决时的时间窗T CRmaxHyst。缩放参数就是小区选择和重选参数中用到的一些次之参数，其实就是一个值，可以将终端设备的移动状态的各个参数都乘以一个缩放因子再用到小区选择或重选的判决中，以此来降低移动速度对终端设备移动性能的影响。基于频率的小区重选优先级参数是指不同频率之间的绝对优先级，是终端设备在进行小区选择和重选时需要考虑的参数。
可选地，在本申请实施例中该终端设备获取用于在非激活态下执行小区选择和重选的移动性控制参数，包括：该终端设备从网络设备发送的RRC专用信令中，获取针对非激活态配置的移动性控制参数。
网络设备可以专门为RRC非激活态下的终端设备配置专门的移动性控制参数以供终端设备在处于RRC非激活态下时进行小区选择和重选，为RRC非激活态下的终端设备配置专门的移动性控制参数，使得终端设备的移动性控制更加准确。网络设备可以通过RRC专用信令向终端设备指示该移动性控制参数。
进一步地，终端设备可以接收该网络设备发送的无线资源控制RRC连接释放消息，该RRC连接释放消息用于指示该终端设备进入非激活态，该RRC连接释放消息中携带该移动性控制参数；该终端设备可以从该RRC连接释放消息中，获取该针对非激活态配置的移动性控制参数。
在终端设备处于RRC激活态时，如果暂时没有业务进行，网络设备可以指示终端设备进入非激活态，例如，可以在该RRC连接释放消息中添加一个指示或释放原因值，来指示终端设备进入非激活态。同时可以在该RRC连接释放消息中携带网络设备为终端设备配置的针对非激活态的移动性控制参数。
可选地，在本申请实施例中，该终端设备获取用于在非激活态下恢复无线资源控制RRC连接的移动性控制参数，包括：该终端设备从系统广播消息中，获取该移动性控制参数。
如果终端设备能够从RRC专用信令中获取该移动性控制参数，则终端设备可以使用该RRC专用信令中获取到的移动性控制参数执行小区选择和重选；若果终端设备不能从RRC专用信令中获取该移动性控制参数，则终端设备可以使用从系统广播消息中获取到的移动性控制参数执行小区选择和重选。
可选地，在本申请实施例中，该方法还包括：若该终端设备从该系统广播消息中获取到针对非激活态配置的移动性控制参数，在该终端设备处于非激活态时使用针对非激活态配置的移动性控制参数执行小区选择和重选；或若该终端设备未从该系统广播消息中获取到针对非激活态配置的移动性控制参数，在该终端设备处于非激活态时使用针对空闲态配置的移动性控制参数执行小区选择和重选。具体地，系统广播可以广播针对空闲态配置的移动性控制参数，也可以再广播针对非激活态配置的移动性控制参数。
