  • conditional PSCell addition process is different from the traditional PSCell addition process:
  • the traditional PSCell addition requires the terminal to report the measurement result first, and then the MN communicates with the target SN according to the measurement result, and then sends the access resource of the target PSCell reserved by the target SN to the terminal to enable it to access the target SN.
  • the MN can communicate with the candidate target SN (possibly more than one) in advance to send the reserved access resources to the terminal, and then execute the addition trigger condition (signal threshold) of the PSCell addition and the candidate target PSCell information is sent to the terminal.

  • the signal thresholds corresponding to the same report/execution event are different. It is easy to imagine that the time for the terminal to add a conditional PSCell is shorter, so it should be located closer to the target PSCell for operations. For the traditional PSCell adding process, it takes a longer time for the terminal to start to operate, and then the terminal needs to report the event earlier. Specifically, as shown in FIG. 2 , the signal threshold of the traditional PSCell addition process corresponds to the signal range 22 , the signal threshold of the conditional PSCell addition process corresponds to the signal range 24 , and the signal range 22 is greater than the signal range 24 . When the terminal moves into the signal range 22 , the report/execution event of the traditional PSCell adding process can be triggered; and when the terminal moves into the signal range 24 , the conditional PSCell adding process can be triggered.
  • the terminal When the terminal accesses a new PSCell, if it encounters problems such as random access, or if it detects a radio link failure (RadioLinkFailure, RLF) problem on the SCG after accessing the target PScell, the terminal will provide the master with the measurement configuration previously.

For example, in a load balancing function, it is decided that a terminal is handed over from a serving cell due to load conditions rather than radio conditions. In this case, the terminal only needs to detect that the target cell is better than a certain signal level value and can provide sufficient coverage.
  • the B1 event can be used for the inter-system handover procedure, and does not depend on the coverage of the serving cell.

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
图1示出了本申请一个实施例提供的基于双连接的移动通信系统的示意图。该移动通信系统包括：主节点(Master Node，MN)12、辅节点(Primary Node，SN)14以及终端16。
MN12的小区包括：主小区(Primary Cell，PCell)和辅小区(Secondary cell，SCell)。MN12的小区统称为主小区组(MasterCellGroup，MCG)。
SN14的小区包括：主辅小区(Primary Secondary Cell，PSCell)和辅小区。SN14的小区统称为辅小区组(SecondaryCellGroup，SCG)。
双连接的作用是为已接入主小区并且处于连接态的终端16提高吞吐量。也即，用SN14上的小区为终端提供额外的频谱资源。
上述MN 12和SN 14均为接入网络设备，接入网设备是一种部署在接入网中用于为终端16提供移动通信功能的装置。接入网设备可以包括各种形式的宏基站，微基站，中继站，接入点，定位管理功能实体(Location Management Function，LMF)等等。在采用不同的无线接入技术的系统中，具备接入网设备功能的设备的名称可能会有所不同，例如在5G NR系统中，称为gNodeB或者gNB。随着通信技术的演进，“接入网设备”这一名称可能会变化。为方便描述，本申请实施例中，上述为终端16提供移动通信功能的装置统称为接入网设备。接入网设备与终端16之间可以通过空口建立连接，从而通过该连接进行通信，包括信令和数据的交互。接入网设备的数量可以有多个，两个邻近的接入网设备之间也可以通过有线或者无 线的方式进行通信。终端16可以在不同的接入网设备之间进行切换，也即与不同的接入网设备建立连接。
终端16的数量通常为多个，每一个接入网设备所管理的小区内可以分布一个或多个终端16。终端16可以包括各种具有移动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，以及各种形式的用户设备(User Equipment，UE)、移动台(Mobile Station，MS)等等。为方便描述，本申请实施例中，上面提到的设备统称为终端16。
本公开实施例中的“5G NR系统”也可以称为5G系统或者NR系统，但本领域技术人员可以理解其含义。本公开实施例描述的技术方案可以适用于5G NR系统，也可以适用于5G NR系统后续的演进系统。
传统PSCell添加过程：
1.MN为终端发送测量配置，该测量配置包括：需要测量的空口频率、测量上报事件等。
2.终端根据MN下发的测量配置进行测量。当测量结果满足测量上报事件时，向主节点上报相应的测量报告。
3.MN根据终端上报的PCell的测量报告，找到合适的目标SN以及目标PScell，指示终端接入该合适的目标PScell。
条件性PSCell添加过程与传统PSCell添加过程的不同：
传统PSCell添加要求终端先上报测量结果，MN再根据测量结果与目标SN进行沟通，继而将目标SN预留的目标PSCell的接入资源发送给终端以使其接入目标SN。而对于条件性PSCell添加，MN可以提前与候选目标SN(可能不止一个)提前沟通预留的接入资源发送给终端，再一并将执行PSCell添加的添加触发条件(信号阈值)和候选目标PSCell的信息发送给终端。当添加触发条件被满足时，终端可以自主地进行PSCell添加的操作。这样一来，SN添加速度会加快，更好的适应终端的当前状态。
需要注意的是，对于传统PSCell添加过程和条件性PSCell添加过程，同样的上报/执行事件对应的信号阈值是不同的。很容易想到，终端在做条件性PSCell添加时经历的时间更短，那么它应该位于更接近目标PSCell的位置做操作即可。而对于传统PSCell添加流程，终端要经历更长时间才能开始做操作，继而就需要终端更早地做事件上报。具体如图2所示，传统PSCell添加过程的信号阈值对应信号范围22，条件性PSCell添加过程的信号阈值对应信号范围24，信号范围22大于信号范围24。当终端移动至信号范围22内即可触发传统PSCell添加过程的上报/执行事件；而当终端移动至信号范围24内才会添加触发条件性PSCell添加过程。
辅小区组失败信息报告(SCG failure information reporting)
当终端接入新的PSCell时候如果遇到随机接入等问题，或者在接入目标PScell后遇检测到SCG上无线链路失败(RadioLinkFailure，RLF)问题，则终端会向之前提供测量配置的主节点(MN)上报辅小区组失败信息报告，帮助MN为终端调整条件性PSCell添加的添加触发条件(trigger)，也即信号阈值。
上报的具体参数包括：
Figure PCTCN2021132463-appb-000001
failuretype------指出失败原因，主要有两类：空口链路质量太差导致RLF和在接入目标PScell时发生随机接入问题。
Figure PCTCN2021132463-appb-000002
measResultFreqList-------包含终端被配置的测量频率上的测量结果。
Figure PCTCN2021132463-appb-000003
位置信息-------终端发生SCG失败时的地理位置。
A4事件(邻小区的测量结果高于门限值)
当邻小区的测量结果比定义的信号阈值更好时触发A4事件。A4事件可用于不依赖于服务小区覆盖范围的切换过程。例如，在负载平衡功能中，由于负载条件而不是无线条件，决定终端从服务小区切换出去。在这种情况下，终端只需要检测目标小区优于某个信号电平值，并能提供足够的覆盖范围。
Mn+Ofn+Ocn–Hys>Thresh(Trigger Condition)——-触发条件
Mn+Ofn+Ocn+Hys<Thresh(CancellationCondition)-撤消条件
B1事件(异系统的邻小区超出门限值)
B1事件可用于系统间切换流程，而不取决于服务小区的覆盖范围。例如，在负载均衡特性中，由于负载条件而不是无线条件，决定将UE从5G(NR)网络中切出。在这种情况下，UE只需要检测其他网络的目标小区(例如LTE)是否优于某个信号电平阈值，并能提供足够的覆盖范围。
Mn+Ofn+Ocn–Hys>Thresh——触发条件
Mn+Ofn+Ocn+Hys<Thresh——撤消条件
其中，Mn是邻小区的测量结果，比如邻小区的参考信号接收功率(Reference Signal Received Power，RSRP)；Ofn是异系统的频率偏移量；Ocn是邻小区的小区偏移量。Hys是当前事件的迟滞系数；Thresh为门限值。Mn在RSRP情况下用dBm表示，在RSRQ和RS-SINR情况下用dB表示。Ofn,Ocn,Hys用dB表示。阈值与Mn用同一单位表示。
由于辅小区组失败信息报告的内容非常有限，MN根据该报告无法确定应该为终端预留多久的接入资源，也不知道终端添加上候选PSCell是否过早，而会发生SCG失败的问题；或者发生终端在添加PSCell不久之后，又请求PSCell更改。
因此，本申请实施例提供了一种终端辅助网络优化条件性PSCell添加过程的配置的技术方案。如图3所示，终端在执行条件性PSCell添加过程后，向网络上报第一信息，该第一信息是与条件性PSCell添加有关的信息；网络根据该第一信息，优化终端的条件性PSCell添加过程的配置信息。基于终端上报第一信息的辅助，网络重新向终端下发优化后的条件性PSCell添加过程的配置信息。

图6示出了本申请一个示例性实施例提供的条件性PSCell添加的优化方法的流程图。本实施例以该方法由终端执行来举例说明。该方法包括：
步骤301：终端基于第一配置信息，执行条件性PSCell添加；
第一配置信息包括但不限于：条件性PSCell添加的添加触发条件，候选PSCell预留的接入资源中的至少一种。该添加触发条件包括：A4事件和/或B1事件的具体参数。
步骤302：终端在条件性PSCell添加失败的情况下，向网络设备发送SCG失败信息报告或上行信息响应，该SCG失败信息报告或上行信息响应携带有第一信息；
示意性的，终端向网络设备发送SCG失败信息报告，该SCG失败信息报告携带有第一信息；或，终端向网络设备发送上行信息响应，该上行信息响应携带有第一信息。
示意性的，终端向网络设备发送SCG失败信息报告，该SCG失败信息报告中的一个或多个比特位为指示信息，该指示信息用于指示终端具有第一信息。网络设备向终端发送上报信令，终端向网络设备发送上行信息响应，上行信息响应携带有第一信息。
在一些实施例中，第一信息包括如下信息中的至少一种：
·第一时刻到第二时刻之间的时间差，第一时刻是终端接收到条件性PSCell添加信令的时刻，第二时刻是终端执行条件性PSCell添加的时刻；
·面向至少一个候选PSCell(简称候选小区)的添加触发条件；
·至少一个候选PSCell的列表和/或测量结果；
比如，在条件性PSCell添加失败前/时，至少一个候选PSCell的列表和/或测量结果。又比如，在发生SCG失败前/时，至少一个候选PSCell的列表和/或测量结果。
·至少一个非候选PSCell的列表和/或测量结果；
比如，在条件性PSCell添加失败前/时，至少一个非候选PSCell的列表和/或测量结果。又比如，在发生SCG失败前/时，至少一个非候选PSCell的列表和/或测量结果。
·第三时刻到第四时刻之间的时间差，第三时刻是执行PSCell添加的时刻，第四时刻是发生SCG失败时的时刻；
第三时刻是执行条件性PSCell添加的时刻，和/或，第三时刻是执行传统PSCell添加的时刻。
·执行主辅小区添加时的终端的位置信息；
比如，执行主辅小区添加时的终端的实时位置信息；又比如，在执行条件性主辅小区添加前的最近一次记录的位置信息；
·终端的位置信息；
比如，在条件性PSCell添加失败时的终端的实时位置信息；又比如，在条件性PSCell添加失败前的最近一次记录的位置信息；又比如，发生SCG失败时的终端的实时位置信息；又比如，在发生SCG失败前的最近一次记录的位置信息；
·为目标主辅小区配置的添加触发条件；
·第一指示或第二指示，第一指示用于指示终端执行的PSCell添加是条件性PSCell添加，第二指示用于指示终端执行的主辅小区添加是传统PSCell添加；
比如，第一指示为conditional，第二指示为commanded。
·在条件性PSCell添加失败时或发生SCG失败前的邻小区测量结果；
步骤303：网络设备接收SCG失败信息报告或上行信息响应；
网络设备从SCG失败信息报告或上行信息响应中，获取第一信息。
步骤304：网络设备基于第一信息优化条件性PSCell添加的第一配置信息；
网络设备基于第一信息优化条件性PSCell添加的候选PSCell的范围、候选PSCell的个数、添加触发条件、预留的接入资源的时长、预留的接入资源的数量中的一种。
结合参考图7，MN为终端分配了传统SN的添加测量事件上报的A4事件，该A4事件的信号阈值为-65dBm。
终端在移动过程中满足了测量事件上报条件，向MN上报条件，MN与SN协商后，决定由终端可发起条件PSCell添加,继而将候选PSCell的专用接入资源和添加触发条件(-63dBm)发送给终端。随着终端移动，终端监测到候选PSCell的小区信号质量满足了添加触发条件，继而用MN为它预留的专用接入资源添加了PSCell。
终端因为空口链路不稳触发了RLF，或者目标PSCell接入时SCG的定时器T304超时，发生SCG失败。终端上报SCG失败信息报告给MN。MN将第一信息“执行PSCell添加的第一时刻到发生SCG失败的第二时刻之间的时间差”与固定阈值进行比较，在该时间差小于固定阈值的情况下，MN认为本次失败属于“过早添加PSCell”的事件。
MN根据终端上报的配置信息，上调类似地点的添加PSCell事件的阈值为-63dBm。
步骤305：网络设备向终端发送优化后的第二配置信息。
网络设备向当前终端或处于类似终端的其它终端发送优化后的第二配置信息，比如A4事件的信号阈值为-60dBm。
综上所述，本实施例提供的方法，通过网络设备接收终端发送的第一信息，使得网络设备能够基于第一信息优化为条件性PSCell添加配置的接入资源和添加触发条件，一方面可以避免接入资源的浪费，另一方面可以提高终端在执行条件性PSCell添加时的成功率，减少SCG失败发生的可能性。
针对成功添加条件性PSCell的情况：
图8示出了本申请一个示例性实施例提供的条件性PSCell添加的优化方法的流程图。本 实施例以该方法由终端和网络设备执行来举例说明。该方法包括：
步骤401：终端基于第一配置信息，执行条件性PSCell添加；
第一配置信息包括但不限于：条件性PSCell添加的添加触发条件，候选PSCell预留的接入资源中的至少一种。该添加触发条件包括：A4事件和/或B1事件的具体参数。
步骤402：终端在条件性PSCell添加成功的情况下，向网络设备发送成功添加PSCELL信息报告或上行信息响应，该成功添加PSCell信息报告或上行信息响应携带有第一信息；
示意性的，终端向网络设备发送成功添加PSCell信息报告，该成功添加PSCell信息报告携带有第一信息；或，终端向网络设备发送上行信息响应，该上行信息响应携带有第一信息。
示意性的，终端向网络设备发送成功添加PSCell信息报告，该成功添加PSCell信息报告中的一个或多个比特位为指示信息，该指示信息用于指示终端具有第一信息。网络设备向终端发送上报信令，终端向网络设备发送上行信息响应，上行信息响应携带有第一信息。
示意性的，终端在条件性PSCell添加成功且满足上报触发条件的情况下，向网络设备发送第一信息，该上报触发条件包括如下条件中的至少一个：
·第一时刻到第二时刻之间的时间差大于第一阈值，第一时刻是终端接收到所述条件性主辅小区添加信令的时刻，第二时刻是终端执行条件性PSCell添加的时刻；
该时间差大于第一阈值，说明终端执行条件性PSCell添加的时刻太晚。
·第二时刻到第五时刻之间的时间差大于第二阈值，第二时刻是执行条件性主辅小区添加的时刻，第五时刻是成功完成条件性PSCell添加的时刻。
该时间差大于第二阈值，说明终端可能遇到了随机接入问题，无法顺利接入目标PSCell。比如在第一配置信息中预留的接入资源较少的情况下，终端在等待较长时间后才能接入目标PSCell。
其中，第一阈值是预定义的，或预配置的，或网络设备配置的；第二阈值是预定义的，或预配置的，或网络设备配置的。
在一些实施例中，第一信息包括如下信息中的至少一种：
·第一时刻到第二时刻之间的时间差，第一时刻是终端接收到条件性PSCell添加信令的时刻，第二时刻是终端执行条件性PSCell添加的时刻；
·面向至少一个候选PSCell(简称候选小区)的添加触发条件；
·至少一个候选PSCell的列表和/或测量结果；
比如，在条件性PSCell添加成功前/时，至少一个候选PSCell的列表和/或测量结果。
·至少一个非候选PSCell的列表和/或测量结果；
比如，在条件性PSCell添加成功前/时，至少一个候选PSCell的列表和/或测量结果。
·执行主辅小区添加时的终端的位置信息；
比如，执行主辅小区添加时的终端的实时位置信息；又比如，在执行条件性主辅小区添加前的最近一次记录的位置信息。
·在PSCell添加成功时的终端的位置信息；
比如，PSCell添加成功时的终端的实时位置信息；又比如，在PSCell添加成功前的最近一次记录的位置信息。
·为目标PSCell配置的添加触发条件；
·第一指示或第二指示，第一指示用于指示终端执行的PSCell添加是条件性PSCell添加，第二指示用于指示终端执行的主辅小区添加是传统PSCell添加；
·在PSCell添加成功前的邻小区测量结果。
步骤403：网络设备接收成功添加PSCell信息报告或上行信息响应；
网络设备从成功添加PSCell信息报告或上行信息响应中，获取第一信息。
在一个示例中，第一信息包括：成功添加PSCell时的邻小区测量结果、第一时刻到第二时刻之间的时间差、成功添加PSCell时的位置信息。
步骤404：网络设备基于第一信息优化条件性PSCell添加的第一配置信息；
网络设备基于第一信息优化条件性PSCell添加的候选PSCell的范围、候选PSCell的个数、添加触发条件、预留的接入资源的时长、预留的接入资源的数量中的一种。
示意性的，MN根据该第一信息调整为终端配置的候选PSCell的范围/个数，比如如果小区3的测量结果表明小区3适合作为候选PSCell却没有出现在候选PSCell范围内，则在未来将小区3添加进候选小区。又比如，MN为终端配置的候选PSCell的专用接入资源的预留时间进行相应优化，比如：终端实际评估时间为两秒，而为终端预留专用接入资源的时间为7秒，则MN可以在后续优化的第二配置信息中进行缩减。
步骤405：网络设备向终端发送优化后的第二配置信息。
网络设备向当前终端或处于类似终端的其它终端发送优化后的第二配置信息。
综上所述，本实施例提供的方法，通过网络设备接收终端发送的第一信息，使得网络设备能够基于第一信息优化为条件性PSCell添加配置的接入资源和添加触发条件，一方面可以避免接入资源的浪费，另一方面可以提高终端在执行条件性PSCell添加时的成功率，减少SCG失败发生的可能性。
