Description

信息传输方法、相关设备及介质 技术领域
本申请涉及通信技术领域，尤其涉及一种信息传输方法、相关设备及介质。
背景技术
随着通信技术的发展，双连接技术应运而生。通过双连接技术，终端可以和两个基站进行通信，由此可以提升用户吞吐量，有助于提升数据传输速率及实现负载均衡等等。在双连接系统的通信过程中，可能会出现主小区组(Master Cell group，MCG)失败或辅小区组(Secondary Cell group，SCG)失败的情况。发明人发现，终端在检测到MCG失败或SCG失败之后，会上报各个小区的参考信号接收功率(Reference Signal Received Power，RSRP)或参考信号接收质量(Reference Signal Receiving Quality，RSRQ)结果，以便于主节点(Master Node，MN)根据终端上报的信息进行恢复配置。比如，终端在检测到MCG失败如MCG无线链路失败(Radio Link failure，RLF)之后，上报给MN的辅助信息主要是MCG失败的原因以及各个小区的小区RSRP、RSRQ结果，进而MN根据这些RSRP、RSRQ结果决定MCG失败的恢复配置；又如，终端在检测到SCG失败之后，上报给MN的辅助信息主要是SCG失败的原因以及各个小区的小区RSRP、RSRQ结果，进而MN根据终端的上报信息决定是保留当前SCG，更改SCG，还是释放SCG。
然而，发明人意识到，很多场景下，基于RSRP、RSRQ结果来进行恢复配置容易导致采取的恢复配置不可靠，使得影响了终端的业务体验。例如，在非地面通信网络(Non Terrestrial Network，NTN)中，与地面网络相比，NTN中终端与卫星之间的空间路损随距离变化并不像地面网络那么显著，导致RSRP、RSRQ结果将不能准确的描述终端在网络中的实际覆盖情况，由此不能准确的反映信道质量。此时，如果基于RSRP、RSRQ结果来进行恢复配置，会导致恢复配置不可靠。比如，对于MCG失败如MCGRLF的情况，如果MN仍只依靠终端上报的RSRP、RSRQ结果进行恢复配置，可能会导致配置了一个真实信道质量并不好的PCell，这样会影响终端的业务体验，恢复配置不可靠；又如，对于SCG失败的情况，MN依靠终端上报的RSRP、RSRQ结果进行恢复配置，可能会导致配置了一个真实信道质量并不好的PSCell，同样会影响终端的业务体验，恢复配置不可靠。由此可见，如何提升MCG失败或SCG失败场景下的恢复配置的可靠性成为亟需解决的问题。

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。
可以理解，本申请的技术方案可具体应用于多连接系统，该多连接系统可包括MN和至少一个SN。其中，多连接系统可涉及第五代移动通信(the 5th Generation，5G)如新无线/新空口(New Radio，NR)网络、长期演进(Long Term Evolution，缩写：LTE)网络或未来通信网络等，比如该MN可以NR基站，也可以为LTE基站；SN也可以为NR基站，或者可以为LTE基站，等等，在此不做限制。
请参见图1a，是本申请实施例提供的一种多连接系统的架构示意图。如图1a所示，该多连接系统包括终端、MN和至少一个SN(图中仅示出一个SN)，终端可以分别与MN、SN进行通信，比如终端可以直接与SN进行通信，或者通过MN与SN进行通信等等。
示例的，该多连接系统可以为LTE-NR双连接(LTE-NR Dual Connectivity，EN-DC)系统，也即，将LTE基站作为MN，NR基站作为SN。由于在NR早期部署时，完整的NR覆盖很难获取，所以典型的网络覆盖是广域的LTE覆盖和NR的孤岛覆盖模式；而且，大量的LTE部署在6GHz以下，可用于5G的6GHz以下频谱很少，所以NR研究6GHz以上的频谱应用。然而，由于高频段覆盖有限、信号衰落快，同时为了保护移动运营商前期在LTE投资等原因，提出了LTE和NR之间紧密互通(tight interworking)的工作模式，即EN-DC，以尽快实现5G网络部署和商业应用。请参见图1b，是本申请实施例提供的一种EN-DC系统的架构示意图。如图1b所示，示出了EN-DC的网络部署和组网架构，其中en-gNB可以为MN或SN。MN主要提供RRC控制功能以及通向CN的控制面；SN可以配置辅助的信令，例如SRB3，主要提供数据传输功能。MN的主小区为PCell，SN的主小区为PSCell(primary secondary cell)。
在本申请中，MN还可叫做主站、MN节点或其余名称，SN还可叫做辅站、SN节点或其余名称，本申请不做限定。
可以理解，本申请的技术方案也可以应用于其他多连接系统，比如支持其他DC模式。例如，可以为NE-DC，5GC-EN-DC，NR DC等等，此处不一一列举。对于EN-DC，接入网络连接的核心网是演进的分组核心网(Evolved Packet Core，EPC)，而其他DC模式连接的核心网是5GC(5G Core Network)。
在多连接系统中，可能会出现MCG失败和/或SCG失败的情况。由此，在MCG失败和/或SCG失败的情况下，本申请可通过上报终端的位置信息、时延信息、距离信息等上报参数给网络侧，以便于网 络侧根据这些上报参数进行恢复配置。例如，在MCG失败如MCG RLF的情况下，终端可以上报位置信息、时延信息、距离信息等上报参数中的至少一种；和/或，在SCG失败的情况下，终端可以上报时延信息、距离信息等上报参数中的至少一种。由此网络设备可以基于这些信息进行数据恢复处理，这就有助于提升MCG失败和/或SCG失败场景下的恢复配置的可靠性，提升终端业务体验。
在一些实施例中，本申请的技术方案还可以应用于NTN场景中。其中，NTN一般采用卫星通信的方式向地面用户提供通信服务。卫星按照轨道高度的不同可以分为分为低地球轨道(Low-Earth Orbit，LEO)卫星、中地球轨道(Medium-Earth Orbit，MEO)卫星、(地球同步轨道Geostationary Earth Orbit，GEO)卫星、高椭圆轨道(High Elliptical Orbit，HEO)卫星等等，此处不一一列举。
其中，对于LEO：LEO的高度范围为500km～1500km，相应轨道周期约为1.5小时～2小时。用户间单跳通信的信号传播延迟一般小于20ms。最大卫星可视时间20分钟。信号传播距离短，链路损耗少，对用户终端的发射功率要求不高。
对于GEO：GEO的轨道高度为35786km，围绕地球旋转周期为24小时，用户间单跳通信的信号传播延迟一般为250ms。
卫星采用多波束覆盖地面，比如一颗卫星可以形成几十甚至数百个波束来覆盖地面，一个卫星波束可以覆盖直径几十至上百公里的地面区域。由此可以保证卫星的覆盖以及提升整个卫星通信系统的系统容量。
可选的，卫星的网络架构可以包括两种，一种是透明转发(transparent payload)的卫星网络架构，一种是再生转发(regenerative payload)的卫星网络架构。请参见图2a，是本申请实施例提供的一种基于透明转发的卫星网络结构示意图。如图2a所示，在基于透明转发的系统中，卫星可作为地面站，UE可通过卫星和NTN网关(Gateway)与基站(如gNB)进行通信，以通过核心网(如5G CN)实现和数据网络(Data Network)的数据交互。请参见图2b，是本申请实施例提供的一种基于再生转发的卫星网络结构示意图。如图2b所示，在基于透明转发的系统中，卫星作为基站；如在多连接系统中，该卫星可以为MN，也可以为SN。其中，卫星和NTN gateway(通常位于地面)之间的无线链路为feeder link。
相比地面蜂窝网通信，卫星通信具有很多独特的优点，包括覆盖广、稳定性高等。例如，卫星通信不受用户地域的限制，比如一般的陆地通信不能覆盖海洋、高山、沙漠等无法搭设通信设备或由于人口稀少而不做通信覆盖的区域，而对于卫星通信来说，由于一颗卫星即可以覆盖较大的地面，加之卫星可以围绕地球做轨道运动，因此理论上地球上每一个角落都可以被卫星通信覆盖覆盖范围广。又如，卫星通信有较大的社会价值。卫星通信在边远山区、贫穷落后的国家或地区都可以以较低的成本覆盖到，从而使这些地区的人们享受到先进的语音通信和移动互联网技术，有利于缩小与发达地区的数字鸿沟，促进这些地区的发展。再如，卫星通信距离远，且通信距离增大通讯的成本没有明显增加。再如，卫星通信的稳定性高，不受自然灾害的限制。
针对NTN场景，本申请可提供一种终端辅助网络进行SCG/MCG失败处理的方法，通过在MCG失败信息中引入终端位置信息，和/或，在SCG/MCG失败信息中引入与终端位置相关的时延信息和/或距离信息，使得网络侧可以结合这些信息进行恢复配置。比如可结合这些信息进行信道质量的评估，进而选择信道质量较好的小区进行数据恢复处理。相比只依赖RSRP、RSRQ进行数据恢复处理相比，可以有效降低由于RSRP、RSRQ测量误差带来的信道质量判断上的误差，从而有助于NTN中MCG失败和/或SCG失败场景下的恢复配置的可靠性，进而可提高通信效率。
可选的，SCG失败的场景可以包括以下任一种：SCG RLF；SN添加/变更失败；对于双连接模式如EN-DC、NGEN-DC和NR DC，使用SRB3传输的SCG配置失败或基于条件的PSCell变更(Conditional PSCell Change，CPC)配置失败；对于双连接模式如EN-DC、NGEN-DC和NR DC，针对SRB3的SCG RRC完整性验证失败；对于双连接模式如EN-DC、NGEN-DC和NR DC，在PSCell上持续上行(up link，UL)先侦听后传输(Listen Before Talk，LBT)失败；对于接入回程一体化移动终端(Integrated Access and Backhaul-Mobile Termination，IAB-MT)，接收到来自SCG的BH RLF指示；CPC执行失败。
在一些实施例中，在终端的MCG发生RLF的情况下，终端可发起无线资源控制(Radio Resource Control，RRC)连接重建立过程。考虑到RRC连接重建立过程中需要进行小区选择，随机接入等，耗时较长，并且会对数据传输造成中断，因此在R16的MR-DC增强项目中引入了快速MCG失败恢复。对于配置了MR-DC的终端，当终端检测到MCG RLF，且SCG链路可用时，可以通过SCG链路进行MCG失败的信息上报和恢复，从而避免触发RRC连接重建立过程。在快速MCG链路恢复期间，终端将挂起所有无线承载的MCG传输，并通过SN向MN发送第一失败信息如MCGFailureInformation消息。可选的，该第一失败信息如MCGFailureInformation消息可以通过分裂的信令无线承载1如split SRB1的辅小组分组对应的腿如SCG leg或者信令无线承载3如SRB3传输。在接收到MCGFailureInformation消息后，MN可以进行数据恢复处理，比如向终端发送RRC重配置消息如RRCReconfiguration消息,来自NR的移动性命令消息如MobilityFromNRCommand消息,来自EUTRA的移动性命令消息如MobilityFromEUTRACommand消息或者RRC释放消息如RRCRelease消息,可选的，这些消息通过split SRB1的SCG leg或者SRB3传输。如果终端接收到RRCReconfiguration消息,MobilityFromNRCommand消息或者MobilityFromEUTRACommand消息，则终端可恢复所有无线承载的MCG传输。如果终端接收到RRCRelease消息，则终端可释放所有的无线承载和配置。
可选的，如果终端在发起快速MCG恢复之后的一段时间内没有收到RRCReconfiguration消息,MobilityFromNRCommand消息和MobilityFromEUTRACommand消息，则终端可发起RRC连接重建流程。
进一步可选的，终端可以在MCGFailureInformation消息中携带基于MN和SN下发的测量配置获得的测量结果。在触发了MCG失败的情况下，终端可以依然维护来自MN和SN的测量配置，并且如果可以的话，终端可继续基于该测量配置执行测量。
在一些实施例中，在发生SCG失败的情况下，如果无线承载的MCG传输没有被挂起，则终端可挂起所有无线承载的SCG传输，同时通过SCGFailureInformation消息向MN上报SCG失败，而不是直接触发RRC连接重建立流程。如果在所有无线承载的MCG传输被挂起的情况下检测到SCG失败，则终端可以发起RRC连接重建立流程。
可选的，在一些实施例中，在发生SCG失败的情况下，终端可以仍维护来自MN和SN的测量配置，终端可继续基于该测量配置执行测量。进一步的，终端在SCG失败之后仍可以继续上报基于通过MN转发的SN测量配置下的测量结果。例如，终端可以在第二失败信息如SCGFailureInformation消息中携带基于MN和SN下发的测量配置获得的测量结果。MN可基于SCGFailureInformation消息进行数据恢复处理，比如决定时保持、更改还是释放SCG。进一步可选的，MN可以选择将基于SN配置的测量结果和SCG失败类型转发给旧的SN和/或新的SN。
在本申请中，网络设备可以为网络侧的一种用来发送或接收信息的实体，比如可以为基站，基站可以用于与一个或多个终端进行通信，也可以用于与一个或多个具有部分终端功能的基站进行通信(比如宏基站与微基站之间的通信)。基站可以是长期演进(Long Term Evolution，LTE)系统中的演进型基站(Evolutional Node B，eNB)，还可以是5G系统、NR系统中的基站gNB，等等，此处不一一列举。或者，该网络设备还可以是传输点(transmission point，TP)、接入点(Access Point，AP)、收发点(transmission and receiver point，TRP)、中继设备、中心单元(Central Unit，CU)，或者具备基站功能的其他网络设备等等，本申请不做限定。例如，本申请的网络设备可以为MN或SN。
在本申请中，终端可以是具有通信功能的设备，例如可以是车载设备、可穿戴设备、手持设备(如智能手机)等。该终端还可以叫做其余名称，比如用户设备(User Equipment，UE)、用户单元、移动台(mobile station)、移动单元(mobile unit)、终端设备等等，本申请不做限定。可选的，该终端可以为具备全球导航卫星系统(global navigation satellite system，GNSS)能力的终端。
可以理解，图1a至图1b示出的通信系统、图2a至图2b示出的卫星网络架构等只是作为一种示例，并不构成对本申请的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申 请提供的技术方案对于类似的技术问题，同样适用。
请参见图3，图3是本申请实施例提供的一种信息传输方法的流程示意图。本实施例的方法可应用于上述的多连接系统中，并可具体应用于上述的终端中。其中，该多连接系统包括终端、MN和SN，MN对应的小区为MCG中的小区，SN对应的小区为SCG中的小区。如图3所示，该方法可以包括：
