具体实施方式
下面将结合附图，对本申请实施例中的技术方案进行描述。
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)系统、先进的长期演进(Advanced long term evolution，LTE-A)系统、新无线(New Radio，NR)系统、NR系统的演进系统、非授权频段上的LTE(LTE-based access to unlicensed spectrum，LTE-U)系统、非授权频段上的NR(NR-based access to unlicensed spectrum，NR-U)系统、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、无线局域网(Wireless Local Area Networks，WLAN)、无线保真(Wireless Fidelity，WiFi)、下一代通信系统或其他通信系统等。
通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(Device to Device，D2D)通信，机器到机器(Machine to Machine，M2M)通信，机器类型通信(Machine Type Communication，MTC)，以及车辆间(Vehicle to Vehicle，V2V)通信等，本申请实施例也可以应用于这些通信系统。
可选地，本申请实施例中的通信系统可以应用于载波聚合(Carrier Aggregation，CA)、双连接(Dual Connectivity，DC)、独立(Standalone，SA)组网等场景中。
示例性的，本申请实施例应用的通信系统100如图1所示。该无线通信系统100可以包括网络设备110。网络设备110可以是与终端设备通信的设备。网络设备110可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备进行通信。可选地，该网络设备100可以是GSM系统或CDMA系统中的基站(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 Node B，eNB或eNodeB)，或者是NR系统中的网络侧设备，或者是云无线接入网络(Cloud Radio Access Network，CRAN)中的无线控制器，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、下一代网络中的网络侧设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)中的网络设备等。
该无线通信系统100还包括位于网络设备110覆盖范围内的至少一个终端设备120。终端设备120可以是移动的或者固定的。可选地，终端设备120可以指接入终端、用户设备(User Equipment，UE)、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PLMN中的终端设备等。其中，可选地，终端设备120之间也可以进行终端直连(Device to Device，D2D)通信。
网络设备110可以为小区提供服务，终端设备120通过该小区使用的传输资源(例如，频域资源，或者说，频谱资源)与网络设备110进行通信，该小区可以是网络设备110(例如基站)对应的小区，小区可以属于宏基站，也可以属于小小区(Small cell)对应的基站，这里的小小区可以包括例如城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等，这些小小区具有覆盖范围小、发射功率低的特点，适用于提供高速率的数据传输服务。

在NR系统中，引入了一个新的RRC状态，即RRC_INACTIVE状态。RRC_INACTIVE状态介于RRC_IDLE状态和RRC_CONNECTED状态之间。其中，对于RRC_IDLE状态，其移动性为基于终端设备的小区选择重选，被叫寻呼由核心网(Core Net，CN)发起，寻呼区域由CN配置，基站上不存在终端设备的接入层(Access Stratum，AS)上下文，此时不存在RRC连接。对于RRC_CONNECTED状态，其移动性是由网络设备控制的，终端设备和基站之间可以传输单播数据，基站和终端设备存在终端设备的AS上下文， 网络设备知道终端设备的位置具体是小区级别的，此时存在RRC连接。对于RRC_INACTIVE状态，其移动性是基于终端设备的小区选择重选，CN和无线接入网(Radio Access Network，RAN)之间保持连接，终端设备的AS上下文存在于至少一个基站上，被叫寻呼由接入网触发，寻呼区域由接入网管理，网络设备知道终端设备的位置具体是寻呼区域级别的，终端设备在RAN配置的寻呼区域内移动时不需要通知网络设备，但当移动出寻呼区域时需要通知网络。所述的寻呼区域即基于RAN的通知区域(RAN-Based Notification Area，RNA)
网络设备可以控制终端设备的状态转移，终端设备与网络设备之间通过RRC连接建立过程(Establish)、RRC连接释放过程(Release)、RRC连接恢复过程(Resume)等实现三种RRC状态之间的相互转移。网络设备控制的RRC状态转移的过程中需要网络设备与终端设备之间进行信令交互。
其中，RRC连接建立过程需要三个步骤，其中通过信令承载(Signalling Radio Bearer，SRB)0、SRB 1、SRB 1分别传输RRC建立请求(RRC Setup Request)消息、RRC建立(RRC Setup)消息和RRC建立完成(RRC Setup Complete)消息。
RRC连接释放过程可以使终端设备由RRC_CONNECTED状态转移至RRC_IDLE状态或者RRC_INACTIVE状态，其中通过SRB 1传输RRC释放(RRC Release)消息。
RRC连接恢复过程可以通过三个步骤使终端设备从RRC_INACTIVE状态转移到RRC_CONNECTED，其中通过SRB 0、SRB 1、SRB 1分别传输RRC恢复请求(RRC Resume Request)消息、RRC恢复(RRC Resume)消息、RRC恢复完成(RRC Resume Complete)消息。
RRC连接恢复过程还可以通过两个步骤使终端设备从RRC_INACTIVE状态转移到RRC_IDLE状态。其中通过SRB 0、SRB 1分别传输RRC恢复请求(RRC Resume Request)消息和RRC释放(RRC Release)消息。
RRC连接恢复过程还可以通过两个步骤使终端设备从RRC_INACTIVE状态转移到RRC_INACTIVE状态。其中通过SRB 0、SRB 0分别传输RRC恢复请求(RRC Resume Request)消息和RRC拒绝(RRC Reject)消息。
例如图2所示，终端设备可以通过RRC连接建立过程，从RRC_IDLE状态转移至RRC_CONNECTED状态，以及通过RRC连接释放过程从RRC_CONNECTED状态转移至RRC_IDLE状态。终端设备可以通过挂起的RRC连接释放过程(RRC Release with Suspend)从RRC_CONNECTED状态转移至RRC_INACTIVE状态，以及通过RRC连接恢复过程从RRC_INACTIVE状态转移至RRC_CONNECTED状态。终端设备可以通过RRC连接释放过程从RRC_INACTIVE状态转移至RRC_IDLE状态，具体 地，终端设备可以先由RRC_INACTIVE状态转移至RRC_CONNECTED状态，再由RRC_CONNECTED状态转移至RRC_IDLE状态。
可以看出，网络设备可以通过RRC连接释放过程将RRC_CONNECTED状态的终端设备释放到RRC_INACTIVE状态或者RRC_IDLE状态。并且，终端设备也可以自发地进行状态转移，实现从RRC_INACTIVE状态至RRC_IDLE状态的转移，或者RRC_CONNECTED状态至RRC_IDLE状态的转移。
例如，终端设备在接收到CN的初始寻呼消息时，或者在发起RRC恢复请求时启动定时器T319并在定时器T319超时时，或者在随机接入过程中的MSG 4的完整性保护验证失败时，或者在重选至其他随机接入技术(Random Access Technique，RAT)的小区时，或者驻留任意小区时，终端设备由RRC_INACTIVE状态自主地转移至RRC_IDLE状态。
又例如，终端设备可以在数据非激活定时器(dataInactivityTimer)超时时，由RRC_CONNECTED状态自主地转移至RRC_IDLE状态。其中，该定时器用于控制数据的不活跃操作，RRC_CONNECTED状态下网络设备为终端设备配置该定时器，该定时器的定时时长的单位为秒(s)。该定时器的启动由介质访问控制(Media Access Control，MAC)层控制，当MAC层收发任何专用业务信道(Dedicated Traffic Channel，DTCH)、专用控制信道(Dedicated Control Channel，DCCH)、以及下行方向的公共控制信道(Common Control Channel，CCCH)时，都会启动或重启该定时器，该定时器超时时，MAC层通知RRC层该定时器超时，RRC层执行相应操作，以使终端设备自主地回到RRC_IDLE状态。
但是，对于由RRC_CONNECTED状态至RRC_INACTIVE状态的转移，目前受制于网络设备的控制。终端设备由RRC_CONNECTED状态转移至RRC_INACTIVE状态的过程中，需要等待网络设备发送的RRC释放(RRC Release with Suspend)消息，影响了终端设备的状态转移效率，增加了终端设备的功耗。
因此，本申请实施例提出一种状态转移的方法，该方法能够实现能够实现终端设备由RRC_CONNECTED状态向RRC_INACTIVE状态的转移，同时减小信令开销并降低终端设备的功耗。
以下，将RRC连接状态(RRC_CONNECTED状态)也简称为连接状态，将RRC非激活状态(RRC_INACTIVE状态)也简称为非激活状态或者不活跃状态等，将RRC空闲状态(RRC_IDLE状态)也简称为空闲状态。
图3是本申请实施例的状态转移的方法300的示意性流程图。图3所述的方法可以由终端设备执行，该终端设备例如可以为图1中所示的终端设备120。如图3所示，所述状态转移的方法300可以包括以下步骤中的部分或 全部。其中：
在310中，终端设备在第一定时器超时时，由连接状态转移至非激活状态。
由于终端设备可以基于第一定时器从连接状态转移至非激活状态，即第一定时器超时时从连接状态转移至非激活状态，从而实现了自主的状态转移。由于终端设备不需要等待网络设备发送的RRC连接释放消息，因此减小了信令开销并降低了终端设备的功耗。
可选地，所述方法还包括：所述终端设备在收发逻辑信道时，启动或重启所述第一定时器。
其中，该逻辑信道包括以下中的至少一种：上行的DTCH、上行的DCCH、下行的DTCH、下行的DCCH、以及下行的CCCH。
例如，由终端设备的MAC层控制第一定时器的启动，当MAC层发送DTCH、DCCH、CCCH时或者接收DTCH、DCCH时，启动或重启该第一定时器。该第一定时器超时时，MAC层通知RRC层该第一定时器超时，RRC层执行相应操作，以使终端设备自主地回到非激活状态。
本申请实施例提供第一定时器的两种实现方式。在第一种实现方式中，该第一定时器为前述的数据非激活定时器(dataInactivityTimer)，即重用该dataInactivityTimer。在第二种实现方式中，该第一定时器是为终端设备配置的不同于dataInactivityTimer的定时器。
首先结合图4对第一种方式进行描述。如图4所示，该方法300还可以包括410和420，并且，310可以由430代替。其中：
在410中，网络设备向终端设备发送指示信息。
在420中，终端设备接收网络设备发送的指示信息。
其中，该指示信息用于指示终端设备由连接状态转移至非激活状态。
在430中，终端设备根据该指示信息，在第一定时器超时时，由连接状态转移至非激活状态。
用于控制终端设备由连接状态向空闲状态转移的该第一定时器为dataInactivityTimer，即复用该dataInactivityTimer，而dataInactivityTimer还需要用于控制终端设备由连接状态转移至空闲状态，因此终端设备需要判断该第一定时器超时时应该由连接状态转移至空闲状态还是由连接状态转移至非激活状态。
也就是说，该第一定时器能够用于控制终端设备由连接状态转移至非激活状态，以及能够用于控制终端设备由连接状态转移至空闲状态。
该第一定时器不仅具有控制终端设备由连接状态转移至空闲状态的能力，还被赋予了新的能力，即控制终端设备由连接状态转移至非激活状态的能力。终端设备可以基于网络设备发送的该指示信息，确定该第一定时器超 时时从连接状态转移至非激活状态还是转移至空闲状态。
该实施例中，网络设备通过向终端设备发送指示其转移至非激活状态的该指示信息，从而指示终端设备在第一定时器超时时由连接状态转移至非激活状态，从而终端设备接收到该指示信息后，在第一定时器超时时由连接状态转移至非激活状态。
可选地，如果终端设备没有接收到指示其转移至非激活状态的该指示信息，或者终端设备接收到指示其由连接状态转移至空闲状态的指示信息，那么终端设备在第一定时器超时时由连接状态转移至空闲状态。
例如，该指示信息可以包括1个比特，该比特的值为1时表示终端设备在第一定时器超时时由连接状态转移至非激活状态，和/或该比特的值为0时表示终端设备在第一定时器超时时由连接状态转移至空闲状态。
该指示信息例如可以携带于MAC-小区组配置(MAC-CellGroupConfig)字段中。
终端设备由连接状态转移至非激活状态时，需要使用配置信息(suspendConfig)，该配置信息用于终端设备进入非激活状态。该配置信息例如可以包括以下参数中的至少一种：非激活状态无线网络临时标识(Inactivity-Radio Network Temporary Identity，I-RNTI)、寻呼周期、寻呼区域、用于更新寻呼区域的定时器、下一跳链计数器(Next Hop Chaining Counter，NCC)。终端设备基于这些参数进入非激活状态。
其中，I-RNTI包括全I-RNTI(full I-RNTI)和短I-RNTI(short I-RNTI)，在终端设备发起连接恢复的过程中使用。寻呼周期(ran-pagingcycle)即终端设备使用的RAN寻呼周期。寻呼区域(ran-NotificationAreaInfo)即终端设备的RAN寻呼区域(RNA)的信息。用于更新寻呼区域的定时器即定时器T380，定时器T380用于控制终端设备周期性地更新RAN寻呼区域(RNA)。下一跳链计数器(nextHopChainingCount)用于指示终端设备下一次发起连接恢复过程时使用的NCC值。
如果该指示信息指示终端设备由连接状态转移至非激活状态，那么终端设备需要获取该配置信息。
其中，可选地，该方法还包括：终端设备接收网络设备发送的用于进入非激活状态的配置信息；其中，在430中，所述终端设备根据所述指示信息，在所述第一定时器超时时，由连接状态转移至非激活状态，包括：所述终端设备根据所述指示信息，在该第一定时器超时时，使用所述配置信息由连接状态转移至非激活状态。
或者，可选地，该指示信息为用于所述终端设备进入非激活状态的配置信息。
也就是说，网络设备向终端设备发送该指示信息以指示终端设备转移至 非激活状态时，可以向终端设备发送该配置信息，从而终端设备在第一定时器超时时，根据该配置信息转移至非激活状态。该配置信息例如可以与该指示信息同时发送给终端设备，该配置信息也可以是终端设备离开连接状态之前的任意时刻由网络设备配置给终端设备的。
或者，该指示信息即为该配置信息。网络设备通过该配置信息隐式地指示终端设备转移至非激活状态。例如，终端设备判断是否接收到该配置信息，如果接收到该配置信息，则终端设备在第一定时器超时时根据该配置信息进入非激活状态，如果没有接收到该配置信息，则终端设备在第一定时器超时时进入空闲状态。
当终端设备接收到用于指示非激活状态的指示信息时，该第一定时器用于控制终端设备由连接状态转移至非激活状态。在终端设备未接收到用于指示非激活状态的指示信息或者接收到用于指示空闲状态的指示信息时，该第一定时器还用于控制终端设备由连接状态转移至空闲状态。
因此，通过复用dataInactivityTimer，并基于网络设备的指示，终端设备可以在第一定时器超时时由连接状态转移至非激活状态，从而实现自主的状态转移，而无需等待网络设备的RRC释放消息，提高了状态转移的效率，降低了终端设备的功耗。
上面描述了第一定时器为dataInactivityTimer的情况。但是，第一定时器也可以是为终端设备配置的不同于dataInactivityTimer的定时器。此时也可以将该dataInactivityTimer称为第二定时器，将第一定时器称为非激活状态数据非激活定时器(inactivityStateDataInactivityTimer)。
该第二定时器用于控制终端设备由连接状态转移至空闲状态，即第二定时器超时时终端设备由连接状态转移至空闲状态。而第一定时器用于控制终端设备由连接状态转移至非激活状态，即第一定时器超时时终端设备由连接状态转移至非激活状态。
其中，可选地，所述方法还包括：终端设备在该第一定时器超时时，停止该第二定时器。
也就是说，若第一定时器先超时，则终端设备在该第一定时器超时时由连接状态转移至非激活状态，并且停止第二定时器；和/或，若第二定时器先超时，则终端设备在该第二定时器超时时由连接状态转移至空闲状态，并且停止第一定时器。
同样，如果第一定时器先超时，终端设备需要使用配置信息(suspendConfig)进入非激活状态。该配置信息例如包括以下参数中的至少一种：I-RNTI、寻呼周期、寻呼区域、用于更新寻呼区域的定时器、NCC。
网络设备为终端设备配置第一定时器时，可以同时发送该配置信息，即网络设备连同第一定时器一起将该配置信息发送给终端设备；或者该配置信 息是终端设备离开连接状态之前的任意时刻由网络设备配置给终端设备的。
该第一定时器的信息和/或用于进入非激活状态的该配置信息例如可以携带于MAC-小区组配置(MAC-CellGroupConfig)字段中。
本申请实施例中，通过第一定时器实现终端设备由连接状态至非激活状态的自主转移，提高了状态转移的效率，降低了终端设备的功耗。
本申请实施例中的“自主转移”可以指不依赖于网络设备的RRC连接释放消息(RRC Release with Suspend)的状态转移。终端设备无需等待网络设备的该RRC连接释放消息，在第一定时器超时时可以直接由连接状态转移至非激活状态。
需要说明的是，在不冲突的前提下，本申请描述的各个实施例和/或各个实施例中的技术特征可以任意的相互组合，组合之后得到的技术方案也应落入本申请的保护范围。
