具体实施方式
下面结合附图，对本发明的实施例进行描述。
首选，对本申请中涉及的部分术语及相关技术进行解释说明，以方便理解：
1)终端设备
本申请中的终端设备是一种具有无限通信功能的设备，可以是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等。在不同的网络中终端设备可以叫做不同的名称，例如：用户设备、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、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)、5G网络或未来演进网络中的终端设备等。
2)基站
本申请中的基站也可以称为基站设备，是一种部署在无线接入网用以提供无线通信功能的设备，可以是全球移动通讯(Global System of Mobile communication，简称GSM)或码分多址(Code Division Multiple Access，简称CDMA)中的基站(Base Transceiver Station，简称BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，简称WCDMA)中的基站(NodeB，简称NB)，还可以是长期演进(Long Term Evolution，简称LTE)中的演进型基站(Evolutional Node B，简称eNB或eNodeB)，或者中继站或接入点，NR系统中的传输节点或收发点(transmission reception point，TRP或者TP)或者下一代节点B(generation nodeB，gNB)，无线保真(Wireless-Fidelity，Wi-Fi)的站点、无线回传节点、小站、微站，或者未来第五代移动通信(the 5th Generation Mobile  Communication，5G)网络中的基站等，本申请在此并不限定。
3)空口连接，无线接入网(radio access network，RAN)-核心网(core net，CN)连接；
为了实现终端与网络设备之间的通信，需要建立空口连接和RAN-CN连接。
空口连接，是指终端设备与RAN设备(如基站)之间的连接。空口连接包括终端设备与基站之间的用户面承载，例如LTE系统中的数据无线承载(data radio bearer，DRB)；以及终端设备与基站之间的控制面承载，例如LTE系统中的信令无线承载(signal radio beare，SRB)。
RAN-CN连接，是指RAN设备(如基站)与CN设备之间的连接。RAN-CN连接包括基站与CN设备之间的用户面承载，例如LTE系统中的S1用户面承载；以及基站与CN设备之间的控制面承载。示例的，LTE系统中，CN设备可以是服务网关(serving gateway，SGW)或PDN网关(PDN gateway)PGW，其中，PDN是分组数据网(packet data network)的英文缩写。在NR系统中，CN设备可以是用户面功能(user plane function，UPF)实体。
4)非激活态、空闲态、连接态
非激活态、空闲态和连接态均用于描述终端设备的状态。
非激活态是处于空闲态和连接态之间的状态。处于非激活态的终端，空口的用户面承载已被暂停(suspend)，RAN-CN之间的用户面承载和控制面承载仍被维护。当终端设备发起呼叫或业务请求时，需要激活空口的用户面承载，并重用已有的RAN-CN之间的承载。如果处于非激活态的终端设备需要发送数据，可以通过空口默认的用户面承载实现数据的发送，该空口默认的用户面承载是服务质量(quality of service,QoS)低于已经被暂停的空口的用户面承载。例如在终端设备和基站之间都保留一个DRB配置，当终端设备有数据需要发送时，可以在该默认的用户面承载上直接发送数据，而不用重新激活空口的用户面承载。非激活态的终端设备需要执行小区重选，例如，非激活态的终端设备在移动时是通过小区重选来更换服务小区，而不是连接态时的切换操作来实现服务小区的更换。区别于空闲态，非激活态的终端设备可以触发基于RNA的位置更新，而不是基于跟踪区域(tracking area，TA)的位置更新。
处于空闲态的终端，空口的用户面承载和控制面承载，以及RAN-CN之间的用户面承载已被释放(release)。当终端发起呼叫或业务请求时，需要先建立空口的控制面承载，然后，建立RAN-CN之间的用户面承载，并在建立RAN-CN之间的用户面承载的同时配置空口的用户面承载。
处于连接态的终端，空口的控制面承载已被建立，且已建立默认的用户面承载(包括空口的用户面承载和RAN-CN之间的用户面承载)。如果默认的用户面承载不能满足业务的QoS需求，则建立专用的用户面承载(包括空口的用户面承载和RAN-CN之间的用户面承载)。
5)其他术语
本文中的术语“多个”是指两个或两个以上。
本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
本申请中的术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对 重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。
本申请提供的技术方案可以应用于各种引入了终端设备的非激活态的通信系统，例如，在现有通信系统基础上引入了终端设备的非激活态的5G通信系统、未来演进系统或者多种通信融合系统等等。本申请提供的技术方案可以包括多种应用场景，包括但不限于机器对机器(machine to machine，M2M)、宏微通信、增强型移动互联网(enhance mobile broadband，eMBB)、超高可靠性与超低时延通信(ultra reliable&low latency communication，uRLLC)以及海量物联网通信(massive machine type communication，mMTC)等场景。这些场景可以包括但不限于：终端设备与终端设备之间的通信场景，基站与基站之间的通信场景，基站与终端设备之间的通信场景等。
图1给出了一种通信系统示意图，该通信系统可以包括RAN、CN以及终端设备。无线接入网中包括一个或多个基站。以LTE系统为例，核心网中可以包括一个或多个移动性管理实体(mobility management entity，MME)(图1中仅示出了一个)，与MME连接的一个或多个SGW或者PGW。以新空口(new radio，NR)系统为例，核心网中可以包括接入和移动性管理功能(access and mobility management function，AMF)实体，以及UPF实体。
MME用于管理终端设备在基站和SGW之间的承载建立和配置，当下行数据到达核心网设备(如SGW)时触发对空闲态的终端设备的寻呼。SGW/PGW用于数据的路由和转发，进行用户面的服务质量(quality of service，QoS)控制。AMF用于管理终端设备在基站和UPF之间的承载建立和配置，当下行数据到达核心网节点如UPF时触发对空闲态的终端设备的寻呼。UPF用于数据的路由和转发，进行用户面的QoS控制。
图2给出了一种无线接入网的示意图，无线接入网可以包括至少一个基于无线接入网的通知区域(RAN-based Notification Area，RNA)(图2以示出1个RNA为例进行说明)。RNA中可以包括一个或多个基站/小区。从对终端设备的作用不同的角度来讲，RNA可以包括服务基站、锚点基站，一个或多个其它基站。
服务基站，是指非激活态的终端设备重选到的基站或终端设备在RNA内移动新接入的基站。任一基站可作为一个或多个终端设备的服务基站，同一终端设备的服务基站可以变更。终端设备的服务基站可称为终端设备新接入的基站(也可以称为新基站或者目标基站)。
锚点基站，是指配置终端设备从连接态转换为非激活态的基站，或保存终端设备的上下文(context)信息的基站。终端设备的锚点基站和服务基站可以是相同的，也可以是不同的。终端设备的锚点基站可称为终端设备切换至新基站前所接入的基站(也可以称为旧基站或者源基站)。
其它基站，是指除服务基站和锚点基站之外的基站。
在图2中，假设在t1时刻，终端设备在基站1的覆盖范围内，并从连接态转换为了非激活态；在t2时刻，该终端设备移动到了基站2的覆盖范围内。那么，可以认为：终端设备在基站2的覆盖范围时，基站1为该终端设备的锚点基站，基站2为该终端设备的服务基站。RNA中除该终端设备的锚点基站和服务基站之外的基站，对于该终端设备来说，为其它基站。
处于非激活态的终端设备需要周期性的位置更新，以使得RNA中的锚点基站或服务基站对终端设备的位置有更准确的了解。同时，基于周期性的位置更新操作，有助于服务基站与终端设备之间的状态同步。
图3为非激活态的终端设备进行位置更新的一种实现方式流程示意图。如图3所示：
非激活态的终端设备预先配置一个计时器，当该计时器超时(例如达到周期T)后该终端设备会向基站发送位置更新信令，以上报该终端设备当前的位置信息。上报的位置信息包括但不限于终端当前的服务小区等位置信息。终端设备完成发送位置更新信令后会重置计时器，以便触发下一次更新。
网络侧设备(例如服务基站或锚点基站)如果也维护了位置更新计时器，在收到终端设备发送的位置更新信令后记录该终端设备当前的服务小区，并重置位置更新计时器。
上述终端设备每次在计时器超时后，都会触发位置更新，并发送位置更新信令。终端设备周期性地发送位置更新信令，会占用较多的信令资源，导致信令的开销大。
本申请实施例提供一种通信方法和设备，以减少非激活态的终端设备因位置更新所造成的信令资源的消耗。
图4(a)为本申请实施例提供的通信方法的第一种实现方式的流程示意图。图4(a)所示的实现方式以终端设备处于RNA中，所述RNA中包括基站1和基站2为例进行说明。其中，终端设备是非激活态的终端设备，且处于基站1的覆盖范围内，基站1是终端设备的服务基站，基站2是终端设备的锚点基站。所述方法包括：
步骤101：非激活态的终端设备将待发送的第一数据发送给服务基站，以代替发送位置更新信令；
可选的，所述非激活态的终端设备是在发送位置更新信令的计时器到期后(或超时时)发送所述第一数据。也可以是所述非激活态的终端设备在所述计时器计时的时间距离所述计时器超时或到期的时间小于预设阈值时，发送所述第一数据。
例如，所述非激活态的终端设备用于发送位置更新信令的计时器计时的周期为10毫秒，当所述计时器计时达到10毫秒时所述计时器到期或超时。但所述计时器计时到10毫秒时，所述非激活态的终端设备查询用于缓存待发送的数据的缓存空间中是否缓存有需要发送的数据。如果有需要发送的数据，例如第一数据需要发送，则通过发送所述第一数据来代替发送位置更新信令，并将所述计时器清零以重启所述计时器，即所述计时器从0毫秒开始重新计时。可选的，当需要发送的数据有多个时，可以选择其中的任何一个数据以代替发送位置更新信令。可选的，还可以在所述计时器计时距离超时的时间(10毫秒)小于预设的阈值(例如该阈值为3毫秒)时，查询是否有需要发送的数据。当有需要发送的数据时，例如所述第一数据需要发送，则通过发送所述第一数据以代替发送位置更新信令。例如在所述计时器计时达到7毫秒，或在7毫秒至10毫秒之间的时间范围内，所述非激活态的终端设备通过发送第一数据以代替发送位置更新信令。并且，在计时器达到10毫秒时直接将计时器清零以重新计时，不再发送位置更新信令。上述预设的阈值以3毫秒为例进行说明，在具体实现时，还可以设置其它的阈值，本申请实施例不做限制。只要满足一定时间内通过发送数据以代替发送位置更新信令，都是本申请实施例覆盖的范围。这样能够减少非激活态的终端设备因发送位置更新信令造成的信令资源的占用和消耗。
具体实现时，所述终端设备可以通过服务基站(基站1)与终端设备之间建立的用户面承载或无线承载(Radio Bearer)发送所述第一数据。例如，所述无线承载可以是在终端设备建立连接时配置，并在进入非激活态后保留的承载，也可以是进入非激活态时由基站1新配置的承载。因此在所述终端设备处于非激活态时，能够通过所述无线承载或用户面承 载发送所述第一数据。
可选的，所述终端设备在向基站1发送所述第一数据同时，还可以发送有所述终端设备的标识的信令，例如可以通过RRC信令或MAC CE携带该终端标识。所述终端设备的标识是所述终端设备进入非激活态时由RAN侧(例如锚点基站)分配的。
可选的，所述终端设备在向基站1发送所述第一数据后，重置位置更新计时器。即所述终端设备在向基站1发送所述第一数据以后，所述计时器清零并重新计时。
步骤102：基站1根据接收到的所述第一数据，进行锚点基站的更新；
可选的，基站1维护一个对所述终端设备进行位置更新的计时器。当所述计时器到期或超时，基站1需要更新所述终端设备的位置信息，此时接收到所述终端设备发送的所述第一数据，则基站1以接收所述第一数据代替接收所述终端设备发送的位置更新信令。
基站1也可以在所述计时器超时前的预设时间内，以接收所述第一数据代替接收所述终端设备发送的位置更新信令。例如计时器在计时10毫秒时到期或超时，所述预设时间是3毫秒，则在所述计时器计时到7毫秒至10毫秒的时间段内，基站1接收到所述终端设备发送的所述第一数据，则以接收所述第一数据代替接收所述终端设备发送的位置更新信令。可以理解，上述3毫秒指示举例，在具体实现时，还可以设置其它的阈值，本申请实施例不做限制。
这样，能够减少终端设备发送位置更新信令的数量，进而减少信令资源的开销。
可选的，基站1在获取或记录所述终端设备的位置信息后，将上述计时器清零或重置，即上述计时器重新计时。
基站1在接收到所述第一数据并获取所述终端设备的位置信息后，触发锚点基站的更新。
具体的，基站1可以通过从基站2获取所述终端设备的上下文，以实现对所述终端设备的锚点基站的更新。相应的，基站1获取所述终端设备的上下文后，基站2变更为所述终端设备的其它基站。
可选的，基站1可以通过context fetch操作触发对所述终端设备的锚点基站的更新。
可选的，在实现锚点基站的更新后，即基站1变更为所述终端设备的锚点基站，基站2变更为所述终端设备的其它基站后，更新后的锚点基站(基站1)还可以触发到核心网侧的信令和/或数据通路的变更。
在步骤102完成锚点基站的更新后，所述方法继续执行。为更清楚显示基站1对所述终端设备角色的变更，所述方法继续执行如图4(b)所示：

可选的，所述非激活态的终端设备向服务基站发送位置更新信令，可以是基于周期性的位置更新发送的位置更新信令，也可以是基于位置变动发送的位置更新信令。当所述非激活态的终端设备基于位置变动发送的位置更新信令，发送给服务基站的位置更新信令可 以包括所述终端设备的经纬度信息。
步骤402：所述服务基站触发位置更新，锚点基站记录所述终端设备的位置信息；

本申请实施例中，步骤403和步骤402可以同时执行，也可以在预设时间内先执行步骤403再执行步骤402或在预设时间内先执行步骤402再执行步骤403。为了便于理解，本申请实施例先描述了步骤402，再描述步骤403；并且在图7中，步骤402和步骤403同时进行；这不应当对本申请实施例的范围造成限制。
可选的，所述锚点基站可以是接收核心网中的数据网关发送的、向所述终端设备发送的第二数据。例如，所述锚点基站接收核心网中的数据网关向所述终端设备发送的下行数据，所述下行数据是所述锚点基站接收到的发送给所述终端设备的第二数据。

例如，所述锚点基站中对所述终端设备进行位置更新的计时器是10毫秒，当该计时器计时达到10毫秒时，所述锚点基站接收到所述第二数据并接收到所述服务基站发送的位置信息或位置更新信令，或服务基站转发的第一数据并根据所述第一数据获取终端设备的位置信息，则锚点基站不再触发向所述终端设备的寻呼，根据获取到的所述终端设备的位置信息向所述终端设备发送所述第二数据，并以发送所述第二数据代替发送响应消息。所述响应消息包括对所述第一数据的响应消息或位置更新响应消息。即当所述终端设备发送位置更新信令时，所述锚点基站通过向所述终端设备发送所述第二数据代替发送位置更新响应消息。当所述终端设备发送所述第一数据以代替发送位置更新信令时，所述锚点基站通过向所述终端设备发送所述第二数据代替发送对所述第一数据的响应消息。这样，不仅能够减少触发向所述终端设备的寻呼带来的信令资源的消耗，也可以减少发送位置更新响应消息或对所述第一数据的响应消息对信令资源的消耗，能够提高信令资源的利用率。
在所述计时器超时前的预设时间段内，也可以以发送所述第二数据代替触发向所述终端设备的寻呼和/或代替发送响应消息。例如，所述锚点基站中对所述终端设备进行位置更新的计时器是10毫秒，在所述计时器超时前的3毫秒内，即所述计时器及时到7毫秒至10毫秒的时间段内，所述锚点基站接收到所述第二数据并接收到所述服务基站发送的位置信息或位置更新信令，或所述服务基站转发的第一数据并根据第一数据获取终端设备的位置信息，则锚点基站不再触发向所述终端设备的寻呼，根据获取到的所述终端设备的位置信息 向所述终端设备发送所述第二数据，并以发送所述第二数据代替发送响应消息。
进一步，本申请实施例提供的方法还可以包括：所述锚地基站也可以在对所述终端设备进行位置更新之后的预设时间内，接收到所述第二数据，不再触发向所述终端设备的寻呼。即所述锚点基站可以发送所述第二数据代替触发向所述终端设备的寻呼。例如所述锚点基站中对所述终端设备进行位置更新的计时器是10毫秒，在所述计时器超时后的3毫秒内，所述锚点基站接收到所述第二数据，则所述锚点基站不再触发向所述终端设备的寻呼，直接向所述终端设备发送所述第二数据。这样，能够减少触发向所述终端设备的寻呼带来的信令资源的消耗，提高信令资源的利用率。
可以理解，上述3毫秒的预设时间只是举例，在具体实现时根据具体的实现场景可以设定不同的阈值。
步骤405：所述服务基站将所述第二数据发送给所述终端设备；
例如：当所述终端设备在步骤401中发送的是位置更新信令时，则所述终端设备在收到第二数据时确认位置更新操作成功，即所述服务基站不用再发送位置更新响应消息。当所述终端设备在步骤401发送的是所述第一数据时，则所述终端设备在收到所述第二数据时确认发送所述第一数据成功，即所述服务基站不用再发送对所述第一数据的响应。
可选的，在发送所述第二数据时可以通过携带对于所述第一数据的响应，如RLC ACK等，就不用再单独用专门的消息或信令发送对于所述第一数据的响应。
可选的，所述终端设备可以在接收响应消息(包括位置更新信令的响应消息或对所述第一数据的响应信息)的时间窗或时间段内，接收所述锚点基站发送的第二数据，确认接收到相应的响应消息。以所述终端设备接收所述第二数据确认接收对所述第一数据的响应消息为例，假设所述终端设备通过计时器设定接收所述第一数据响应的时间，例如是3毫秒，即所述终端设备接收对所述第一数据的响应消息的时间窗是3毫秒，在用于接收对所述第一数据的响应消息的计时器到期或超时(即达到3毫秒)以及所述计时器超时后预设时间内(例如超时后2毫秒的时间内)接收到所述第二数据，则所述终端设备确认收到对所述第一数据的响应消息。其中，所述3毫秒和2毫秒只是一种举例，在具体实现时，还可以有其它的实现方式，例如5毫秒等，本发明实施例不做限定。
步骤406：所述终端设备向所述服务基站发送接收到所述第二数据的响应消息；
可选的，如果所述终端设备未接收到所述第二数据，也未接收到响应消息(包括位置更新信令的响应消息或对所述第一数据的响应消息)，则所述终端设备可以重新发送位置更新信令或所述第一数据。即当所述终端设备发送位置更新信令，且在接收所述位置更新信令的响应消息的计时器到期或超时，或超时后预设时间内，仍未收到所述位置更新信令的响应消息或所述第二数据，则所述终端设备重新发送该位置更新信令。当所述终端设备发送所述第一数据以代替发送位置更新信令，且接收所述第一数据的响应消息的计时器到期或超时，或超时后预设时间内，仍未收到对所述第一数据的响应消息或所述第二数据，则所述终端设备重新发送该第一数据。
步骤407：所述服务基站将接收到的响应消息转发给所述锚点基站。
可选的，如果所述锚点基站在预设时间内未接收到所述服务基站转发的、所述终端设备对所述第二数据的响应消息，或所述锚点基站在预设时间内未接收到所述服务基站转发的、所述终端设备对所述第二数据的响应消息而触发重新发送所述第二数据达到预定的次 数的，所述锚点基站可以触发向所述终端设备发送寻呼。
需要说明的是，当所述终端设备位于锚点基站的覆盖范围内时，图7所示的方法就不需要步骤402，锚点基站直接接收所述终端设备发送的位置更新信令或所述第一数据，并获取所述终端设备的位置信息。当接收到所述数据网关发送的所述第二数据时，所述锚点基站直接向所述终端设备发送的第二数据，并以发送所述第二数据代替触发对所述终端设备的寻呼和/或代替发送响应消息。同样能够减少信令资源的消耗。
可选的，本申请实施例提供的方法，还可以用非位置更新的信令代替位置更新信令，以减少发送位置更新信令，降低因发送位置更新信令导致的信令资源的消耗。本申请实施例中的非位置更新信令，包括但不限于：接入层(access stratus，AS)信令或非接入层(non-access stratus，NAS)信令。其中，通过非位置更新信令代替位置更新信令的实现方式，可以参考上述图4(a)、图4(b)、图5、图6和图7中通过发送所述第一数据的实现方式来实现，不再赘述。
