Description

激活连接的方法、设备、系统及存储介质 技术领域
本申请实施例涉及通信技术领域，尤其涉及一种激活连接的方法、设备、系统及存储介质。
背景技术
在DC(Dual Connectivity，双连接)场景下，当终端设备与辅节点之间传输的数据量减少时，可去激活(Deactivate)终端设备与辅节点的连接，以达到节省终端设备能耗的效果。另外，在有数据传输的需要时，也可再激活(Activate)终端设备与辅节点的连接。
一些实现中，激活终端设备与辅节点的连接的过程是由辅节点或主节点发起的，仅适用于有下行数据需要传输的场景。在处于非激活态的终端设备再次有数据传输需求时，却需要额外再建立与辅节点的连接，还有，由于终端设备对于数据传输的需求是动态的，在没有与辅节点连接的条件下，终端设备会与辅节点频繁建立与终止连接，从而造成耗电。
前面的叙述在于提供一般的背景信息，并不一定构成现有技术。

具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，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，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
首先对本申请实施例所涉及的名词进行解释：
双连接：是指终端设备采用同一种无线接入技术接入到两个不同的网络设备；或者，终端设备采用两种不同的无线接入技术同时接入一个网络设备或者两个网络设备。可选地，终端设备与MN(Master Node，主节点)建立的连接称为MCG(Master Cell Group，主小区群)，主小区群里的主小区称为PCell；终端设备与SN(Secondary Node，辅节点)建立的连接称为SCG(Secondary Cell Group，辅小区群)，辅小区群里的主小区称为PScell。主节点和辅节点之间有一条叫做Xn-C的控制面链路，并且至少主节点通过接口NG-C连接到核心网络。
双连接包含EN-DC(EUTRA-NR Dual Connectivity)和MR-DC(Multi-Radio Dual Connectivity，多无线电双连接)。
图1a为EN-DC场景的一种示意图。如图1a所示，终端设备通过接口Uu同时接入两个基站：MeNB和SgNB。具体地，MeNB是为终端设备提供S1-MME连接的4G基站，作为控制面锚点连接到4G核心网，承担所有控制面功能，因此也称为主节点；SgNB为5G基站，没有直接连接到核心网的控制面链路，SgNB与MeNB之间有一条叫做X2-C的控制面链路，SgNB不承担控制面功能，其跟核心网的控制面交互是依靠MeNB来进行，因此被称为辅节点。
图1b为多无线电双连接场景的一种示意图。如图1b所示，终端设备被配置为通过接口Uu分别接入两个不同的节点，并利用由两个不同的节点提供的资源，一个节点提供新空口接入，另一个节点提供E-UTRA或新空口接入。可选地，一个节点充当主节点，另一个节点充当辅节点。主节点和辅节点通过网络接口连接，并且至少主节点连接到核心网络。在NGEN-DC(NG-RAN E-UTRA-NR Dual Connectivity)中，辅节点提供新空口接入，主节点提供E-UTRA接入；在NE-DC(NR-E-UTRA Dual Connectivity)中，主节点提供新空口接入，辅节点提供E-UTRA接入；在NR-DC(NR-NR Dual Connectivity)中，主节点和辅节点均提供新空口接入。
在多无线电双连接中，终端设备配置有两个媒介访问控制实体：一个媒介访问控制实体用于主小区群，另一个媒介访问控制实体用于辅小区群。除PCell之外的主小区群的服务单元只能由主小区群上接收的媒介访问控制协议数据单元中的控制元素激活/停用，并且辅小区群(PSCell除外)的服务单元只能由在辅小区群上接收的媒介访问控制协议数据单元中的控制元素激活/停用。
RA(Random Access，随机接入)：是指从终端设备发送随机接入前导码开始尝试接入网络设备到与网络设备间建立起基本的信令连接之前的过程。终端设备可以在多种可能的场景下发起随机接入。例如，终端设备的状态从空闲态切换为连接态后，终端设备与网络设备建立无线链路过程时发起随机接入；或者，终端设备的状态从非激活态切换到连接态时发起随机接入，等等。
本申请实施例所涉及的随机接入可以包括两步随机接入(还可以称为2-step RA)和四步随机接入(还可以称为4-step RA)，为了便于理解，下面，分别对两步随机接入和四步随机接入的过程进行详细说明。
图2为两步随机接入的流程示意图。参考图2，两步随机接入可以包括：
S201、终端设备向网络设备发送MsgA。
可选地，MsgA包含随机接入前导(preamble)与净荷(payload)。
S202、网络设备向终端设备发送MsgB。
MsgB可以是：竞争解决(Contention Resolution)、回落指示(Fallback Indication)或回退指示(Backoff Indication)等。
图3为四步随机接入的流程示意图。参考图3，四步随机接入可以包括：
S301、终端设备向网络设备发送Msg1。
可选地，Msg1包含：随机接入前导，随机接入前导还可以称为随机接入前导序列、或preamble、或preamble序列。
S302、网络设备向终端设备发送Msg2。
可选地，Msg2可以是：随机接入响应和/或回退指示。回退指示用于指示重传Msg1的回退时间。
对于CFRA(Contention Free Random Access，基于非竞争的随机接入)，终端设备成功接收Msg2后，随机接入过程结束。对于CBRA(Contention Based Random Access，基于竞争的随机接入)，终端设备成功接收Msg2后，还需要继续发送Msg3和接收Msg4。
S303、终端设备向网络设备发送Msg3。
可选地，Msg3是随机接入过程中的第一个调度传输，发送净荷(payload)。
S304、网络设备向终端设备发送Msg4。
可选地，Msg4用于指示该终端设备是否成功的接入到该网络设备。Msg4具有解决竞争冲突的作用。以初始接入为例，冲突的解决是终端设备接收Msg4的PDSCH(Physical Downlink Shared Channel，物理下行共享信道)，通过匹配物理下行共享信道中的CCCH(Common Control CHannel，公共控制信道)服务数据单元(Service Data Unit，SDU)。
非激活态：终端设备在接入网络完成本次数据传输后，网络设备并不会直接让终端设备释放无线资源控制连接进入空闲态，而是由网络设备配置终端设备进入非激活态。终端设备进入非激活态后，不与网络设备进行数据传输，但可以周期性地接收来自网络设备的寻呼。网络设备保留该终端设备所建立的无线资源控制连接的配置、承载的配置、安全配置以及n2接口(5G核心网与基站之间的接口)与该终端设备相关的参数配置，例如，主节点配置了主小区群以及其辅小区(又可以称为“MCG Scell”)，辅节点同样配置了辅小区群及其辅小区(又可以称为“SCG Scell”)等，终端设备也需要保存无线资源控制连接的配置、承载的配置和安全配置等。由于终端设备和网络设备均有该终端设备的无线资源控制连接配置参数，因此进入非激活态的终端设备在有数据传输时，可以利用保存的无线资源控制连接配置参数快速接入网络设备进行数据传输。一些实现中，网络设备通过RRC release(RRC释放)信令指示终端设备进入非激活态。
无线资源控制(连接)恢复过程：是指处于非激活态的终端设备重新接入网络设备，返回连接态的过程。
在双连接场景下，当终端设备与辅节点之间数据量交互减少时，可以去激活终端设备与辅节点的连接，即相对辅节点来说，终端设备处于去激活状态，以达到省电效果。当有数据传输需要时，可再恢复终端设备与辅节点的连接。
一些实现中，通过以下流程激活终端设备与辅节点的连接：
1、如果辅节点存在下行数据需要辅节点提供资源，则辅节点通过向主节点发送辅节点激活请求消息来启动激活连接过程。
或者，对于DRB(Data Radio Bearer，数据无线承载)对应的RLC(Radio Link Control，无线链路控制层协议)承载位于主小区群和辅小区群时，如果主节点存在下行数据需要辅节点提供资源，则主节点启动激活连接过程。
2、主节点在接收辅节点激活请求消息时，或者主节点启动激活连接过程时，主节点向终端设备发送辅小区群激活命令；
3、在接收到辅小区群激活命令时，终端设备回复主节点发送确认；
4、终端设备对辅节点发起随机接入；
5、终端设备上报CSI(Channel State Information，信道状态信息)报告后，恢复与辅节点间的通信。
可见，上述激活终端设备与辅节点的连接的流程是由主节点或辅节点发起的，仅适用于有下行数据需要传输的场景。在处于非激活态的终端设备再 次有数据传输需求时，却需要耗费额外能量建立与辅节点的连接，同时考虑到终端设备对于数据传输的需求是动态的，在没有设置连接条件下容易形成频繁建立连接与终止连接的情况，从而造成耗电。
基于上述问题，本申请提供一种激活连接的方法、设备、系统及存储介质，通过终端设备发起激活终端设备与辅节点的连接的流程，达到有效恢复终端设备与辅节点的连接，从而符合省电节能和/或快速建立连接需求。
本申请实施例提供的激活连接的方法，可以适用于图4所示的通信系统架构示意图。如图4所示，该通信系统包括：AMF/UPF、接入网设备以及终端设备。可选地，接入网设备包括：第一基站和第二基站。示例地，第一基站和第二基站均为新空口系统的基站。图4所示场景中，第一基站和第二基站共用一个AMF/UPF，可选地，第一基站与AMF(Access and Mobile Management Function，接入和移动管理功能)/UPF(User Plane Function，用户平面功能)核心网设备之间通过接口NG-C连接，第一基站与第二基站之间通过接口X2-C连接，终端设备同时接入第一基站和第二基站。当然，在其他场景中，第一基站和第二基站也可以分别拥有各自独立的AMF/UPF，本申请实施例在此并不限定。
需要说明的是，图4所示的通信系统可以适用于不同的网络制式，例如，可以适用于GSM(Global System of Mobile communication，全球移动通讯)、CDMA(Code Division Multiple Access，码分多址)、WCDMA(Wideband Code Division Multiple Access，宽带码分多址)、TD-SCDMA(Time Division-Synchronous Code Division Multiple Access，时分同步码分多址)、长期演进系统及未来的5G等网络制式。可选地，上述通信系统可以为5G通信系统中高可靠与低时延通信的场景中的系统。
终端设备，可以是无线终端设备也可以是有线终端设备。无线终端设备可以是指一种具有无线收发功能的设备，可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、VR(Virtual Reality，虚拟现实)终端设备、AR(Augmented Reality，增强现实)终端设备、工业控制(industrial control)中的无线终端设备、无人驾驶(self driving)中的无线终端设备、远程医疗(remote medical)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备、可穿戴设备等等，在此不作限定。可以理解的是，本申请实施例中，终端设备也可以称为移动终端、UE(User Equipment，用户设备)、系统、订户单元(Subscriber Unit)、订户站(Subscriber Station)，移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)或用户代理(User Agent)，在此不作限定。
在一些实现中，本申请下述各实施例例如可以应用于如下场景：
示例场景一：当用户使用终端设备在浏览视频，终端设备中与视频相关的应用软件会先下载一定量的数据缓存在终端设备中，使得用户体验更为流畅。当缓存数据量达到预设上限阈值后便暂停数据下载，待小于预设下限阈值再继续下载直到缓存数据量达到预设上限阈值，如此反复操作。相对辅节点处于非激活态的终端设备，当数据在下载时传输量较大，需要激活终端设备与辅节点的连接，终端设备通过“获取辅节点激活条件参数，根据辅节点激活条件参数，按照预设规则发送辅节点激活请求，以得到辅节点激活响应，根据辅节点激活响应激活终端设备与辅节点的连接”，从而加速完成下载；反之，当数据传输量较小时，可以去激活终端设备与辅节点的连接，达到省电节能功效。
示例场景二：当用户通过终端设备中应用软件发送短视频、文档、图片或是数据连接请求，如游戏...等，突发的大量上传数据需求需要激活终端设备与辅节点的连接，具体地，终端设备通过“获取辅节点激活条件参数，根据辅节点激活条件参数，按照预设规则发送辅节点激活请求，以得到辅节点激活响应，根据辅节点激活响应激活终端设备与辅节点的连接”，从而加速完成数据上传，提供较好的用户体验。当传输结束或是传输的数据量减小后，可以去激活终端设备与辅节点的连接，达到省电节能功效。
下面以具体实施例对本申请实施例的技术方案以及本申请的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。下面将结合附图，对本申请实施例的实施例进行描述。
图5为本申请一实施例提供的激活连接的方法的信令交互示意图。如图5所示，本实施例的方法包括以下步骤：
S10、获取辅节点激活条件参数。
在处于非激活态的终端设备再次有数据传输需求时，该终端设备获取辅节点激活条件参数。
可选地，该步骤中的“获取”可以包括从终端设备内部获取或者从网络设备获取。具体地，辅节点激活条件参数可以是预先储存于终端设备中的，这样即可从终端设备的内部获取辅节点激活条件参数。或者，该步骤可以具体为：终端设备接收辅节点去激活指示信息，可选地，该辅节点去激活指示信息中携带辅节点激活条件参数，去激活指示信息用于去激活终端设备与辅节点的连接。
可以理解，终端设备在接收辅节点去激活指示信息之后，保存辅节点去激活指示信息中携带的辅节点激活条件参数，这样在后续激活终端设备与辅节点的连接时即可从终端设备内部获取辅节点激活条件参数。
可选地，去激活指示信息可以包括以下至少一种：无线资源控制信令、媒介访问控制协议数据单元中的控制元素或下行控制信息等。示例地，下行控制信息可以具体为PDCCH(Physical Downlink Control Channel，物理下行链路控制信道)和\或PDSCH(Physical Downlink Shared CHannel，物理下行链路共享信道)上的控制单元所指示的信息。
可选地，辅节点激活条件参数是由对应辅节点提供的，由辅节点发送给主节点，再由主节点发送给终端设备；或由辅节点提前发送给终端设备。
S30、根据辅节点激活条件参数，按照预设规则发送辅节点激活请求，以得到辅节点激活响应。
为适应高可靠与低时延通信的低时延需求，针对终端设备与辅节点间连接的恢复，本申请实施例设置预设规则，以在终端设备恢复与辅节点的连接时进行参考。示例性地，预设规则可以具体为恢复终端设备与辅节点的连接的条件，该条件是与辅节点激活条件参数有关的，具体可参考后续实施例。
S50、根据辅节点激活响应激活终端设备与辅节点的连接。
需明确的是，本申请中所述的恢复终端设备与辅节点的连接，是指重新启用与辅节点相关配置信息，例如承载的配置和安全配置等配置信息，激活与辅节点的连接进行数据传输。与辅节点相关配置信息可以是预先储存于终端设备中的，也可以是由网络临时为终端设备配置的，具体可根据实际需求进行设置。示例地，若与辅节点相关配置信息是由网络临时为终端设备配置的，一种具体实现中，上述去激活指示信息还可以用于指示终端设备删除与辅节点相关的配置信息，也就是说处于非激活态的终端设备无需再保留与辅节点相关的配置信息，仅保留与主节点相关的配置信息，以降低终端设备中存储空间的占用。
示例地，若与辅节点相关配置信息是预先储存于终端设备中的，一种具体实现中，上述去激活指示信息还可以用于指示终端设备配置重新启用与辅 节点相关的配置信息或是指示终端设备保存去激活前的相关配置，等再次激活后可以直接使用，满足高可靠低时延的需求。
本申请实施例提供的激活连接的方法，处于非激活态的终端设备获取辅节点激活条件参数，并根据辅节点激活条件参数，按照预设规则发送辅节点激活请求，以得到辅节点激活响应，之后根据辅节点激活响应激活该终端设备与辅节点的连接。由处于非激活态的终端设备根据辅节点激活条件参数，按照预设规则触发该终端设备与辅节点的连接，从而快速激活终端设备与辅节点的连接，减少上行数据传输时延，从而符合高可靠与低时延通信的低时延需求。
在上述实施例的基础上，示例地，辅节点激活条件参数可以包括以下至少一种：上行缓存数据量阈值、电池剩余电量阈值、发射功率阈值或功率余量阈值。
应理解，不同辅节点激活条件参数对应的预设规则也是不同的。因此，上述按照预设规则发送辅节点激活请求的步骤，可以包括以下至少一种：
在终端设备待传输的上行数据量大于或等于上行缓存数据量阈值时，发送辅节点激活请求；
在终端设备的电池剩余电量大于或等于电池剩余电量阈值时，发送辅节点激活请求；
在终端设备的发射功率小于或等于发射功率阈值时，发送辅节点激活请求；
在终端设备的功率余量大于或等于功率余量阈值时，发送辅节点激活请求。

对于终端设备的功率余量大于或等于功率余量阈值的情况，例如，当终端设备需要建立并恢复与辅节点的连接，但终端设备相对主节点的功率余量低于功率余量阈值，则不恢复与辅节点的连接，以达到节能省电效果。反之，当终端设备相对主节点的功率余量高于功率余量阈值，则可以与辅节点恢复连接。同时，基站可以以功率余量阈值作为控制参数，作为上行信令和\或数据传输传输负载平衡。
