Description

配置辅小区组的方法和装置
本申请要求于2020年09月27日提交国家知识产权局、申请号为202011037346.0、申请名称为“配置辅小区组的方法和装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，具体涉及一种配置辅小区组的方法和装置。
背景技术
为使网络技术平滑更替，第五代(5th generation，5G)网络与第四代(4th generation，4G)网络将在较长的时段时间内共存，此时的组网方式即非独立(non-standalone，NSA)组网方式。
一种NSA组网方式是通过4G网络添加辅小区组(secondary cell group，SCG)，该SCG即5G网络，在该NSA组网方式下，终端设备与4G网络和5G网络保持双连接。例如，网络设备确定终端设备具备5G能力后，向终端设备发送4G无线资源控制(radio resource control，RRC)重配置消息，该4G RRC重配置消息中包括5G频点，终端设备根据4G RRC重配置消息的指示测量5G频点，尝试添加SCG。
由于5G频带较宽，终端设备可能不支持网络设备配置的5G带宽。当终端设备不支持网络设备配置的5G带宽时，终端设备需要向网络设备发送4G RRC重建消息，以重建4G网络连接。网络设备接收到4G RRC重建消息后，无法确定终端设备是否支持4G RRC重配置消息指示的5G频点，会再次为终端设备配置SCG，终端设备也会再次重建4G网络连接。最终导致4G网络连接频繁重建，影响通信质量。
发明内容
本申请提供了一种配置SCG的方法，能够避免4G网络连接频繁重建。
第一方面，提供了一种配置SCG的方法，包括：终端设备接收长期演进(longtermevolution，LTE)RRC重配置消息，所述LTE RRC重配置消息包括新无线(newradio，NR)配置参数，所述NR配置参数用于配置SCG；当所述终端设备不支持配置所述SCG时，所述终端设备发送指示信息，所述指示信息用于指示所述SCG发生异常。
终端设备不支持配置SCG，可以被解释为：终端设备支持的带宽与所述NR配置参数中的带宽匹配失败。网络设备收到上述指示信息后，确定终端设备需要释放SCG，则网络设备可以向终端设备发送释放SCG的消息。终端设备释放SCG后无需再发送4G网络重建请求，从而可以避免4G网络连接频繁重建或减少4G网络连接频繁重建次数，提高网络连接的质量。
可选地，还包括：当所述终端设备在目标时段内收到SCG释放消息时，所述终端 设备释放所述SCG；或者，当所述终端设备在目标时段内未收到SCG释放消息时，所述终端设备发送LTE RRC重建消息。
终端设备发送指示信息后，网络设备需要一定的时间做出决策，因此，终端设备在目标时间段不发送LTE RRC重建消息可以减小信令开销。若终端设备在目标时段后仍未收到SCG释放消息，则存在网络设备任务繁忙导致未及时做出决策的可能性，终端设备可以向网络设备发送LTE RRC重建消息，尽快重建4G网络连接，减小SCG配置失败对通信的影响。
可选地，所述目标时段为发送所述指示信息后启动的定时器对应的时段。
上述定时器可以在发送指示信息后立刻启动，也可以在发送指示信息后间隔一段时间启动，终端设备可以通过定时器灵活设置目标时段。
可选地，还包括：当所述终端设备支持的带宽与所述NR配置参数中的带宽匹配失败的次数大于等于第一阈值时，确定不再上报所述SCG的测量报告。
当SCG对应的LTE小区和NR小区的组合匹配失败的次数大于等于第一阈值时，说明终端设备不支持该LTE小区和NR小区的组合，终端设备在该情况下停止上报测量报告能够避免网络设备为终端配置SCG，从而可以避免4G网络连接频繁重建或减少4G网络连接频繁重建次数，提高网络连接的质量。此外，终端设备在该情况下可以停止测量以减小终端设备的功耗。
可选地，还包括：所述终端设备根据组合信息确定所述匹配失败的次数，其中，所述组合信息包括：所述LTE小区的频带标识(identifier，ID)、频点ID和物理小区ID中的至少一个信息，以及所述NR小区的频带ID、频点ID和物理小区ID中的至少一个信息。
可选地，所述指示信息为NR SCG失败信息。
NR SCG失败信息为当前已有的信息，但未应用于通过LTE RRC重配置消息配置NR SCG失败的场景。利用现有的信息指示该场景中SCG发生异常，无需设计新的信息，有利于减小通信复杂度。
第二方面，本申请提供了一种配置SCG的装置，包括用于执行第一方面所述的方法的单元。该装置可以是终端设备，也可以是终端设备内的芯片。该装置可以包括接收单元、发送单元和处理单元。
当该装置是终端设备时，该处理单元可以是处理器，该接收单元和该发送单元可以是收发器；该终端设备还可以包括处理单元和存储单元，该存储单元可以是存储器；该存储单元用于存储指令，该处理单元执行该存储单元所存储的指令，以使该终端设备执行第一方面所述的方法。
当该装置是终端设备内的芯片时，该处理单元可以是芯片内部的处理单元，该输入单元可以是输入/输出接口、管脚或电路等；该处理单元执行存储单元所存储的指令，以使该芯片执行第一方面所述的方法，该存储单元可以是该芯片内的存储单元(例如，寄存器、缓存等)，也可以是位于该芯片外部的存储单元(例如，只读存储器、随机存取存储器等)。
第三方面，本申请提供了一种计算机可读存储介质，该计算机可读存储介质中存储了计算机程序，该计算机程序被处理器执行时，使得处理器执行第一方面所述的方 法。
第四方面，本申请提供了一种计算机程序产品，该计算机程序产品包括：计算机程序代码，当该计算机程序代码被处理器运行时，使得处理器执行第一方面所述的方法。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
首先介绍本申请的应用场景，图1是一种适用于本申请的通信系统的示意图。
通信系统100包括网络设备110和终端设备120。终端设备120通过电磁波与网络设备110进行通信。
在本申请中，终端设备120可以包括各种具有无线通信功能的手持设备、车载设备或者可穿戴设备，例如，第三代合作伙伴计划(3rd generation partnership project，3GPP)所定义的用户设备(user equipment，UE)、移动台(mobile station，MS)等等。
网络设备110可以是3GPP所定义的基站，例如，第五代(the fifth generation，5G)通信系统中的基站(gNB)。网络设备110还可以是中继站、接入点、车载设备、可穿戴设备以及其它类型的通信设备。
通信系统100仅是举例说明，适用本申请的通信系统不限于此，例如，通信系统100中包含更多的网络设备。
网络设备110和终端设备120均同时支持4G网络和5G网络。当网络设备110和终端设备120进行NSA组网时，可以通过4G网络添加SCG来激活5G网络，下面将详细描述本申请提供的配置SCG的方法。
图2是本申请提供的一种配置SCG的方法的示意图。
终端设备120建立与网络设备110建立基于4G网络的RRC连接，当网络设备110确定终端设备120具备5G能力时，网络设备110可以通过LTE RRC重配置消息1为终端设备120配置5G频点，终端设备120根据LTE RRC重配置消息1测量该5G频点，以确定是否支持该5G频点；测量完成后，终端设备120上报该5G频点的测量报告(即，NR小区或SCG的测量报告)。
例如，当网络设备110配置终端设备120测量509166频点时，LTE RRC重配置消息1的内容如下所示。
Figure PCTCN2021118692-appb-000001
Figure PCTCN2021118692-appb-000002
上述消息中，carrierFreq-r15指示了待测量的5G频点。
5G频点的测量报告可以包括5G网络的物理小区标识(physicalcellidentifier，PCI)和信号强度。5G频点的测量报告可以包括如下内容。
Figure PCTCN2021118692-appb-000003
网络设备110收到上述测量报告后，向终端设备120发送LTE RRC重配置消息2，LTE RRC重配置消息2包括上述5G频点和该5G频点对应的5G带宽。随后终端设备120可以执行下列步骤。
S210，接收LTE RRC重配置消息，所述LTE RRC重配置消息包括NR配置参数，所述NR配置参数用于配置SCG。
S210中的LTE RRC重配置消息即前文所述的LTE RRC重配置消息2。该LTE RRC重配置消息例如是RRCConnectionReconfiguration，上述NR配置参数例如是nr-SecondaryCellGroupConfig，包含nr-SecondaryCellGroupConfig的RRCConnectionReconfiguration如下所示：
nonCriticalExtension
nr-Config-r15
setup-nr-config-r15
endc-ReleaseAndAdd-r15:FALSE
nr-SecondaryCellGroupConfig-r15:08 81 85 5C 40 B0 44 31 C5 5F C8 12 0D C4 E8 0F 84 28 10 20 F3 6C 04 1A DD 3A 77 18 16 D1 FA D6 00 4A 3F 21
p-MaxEUTRA-r15:23,0×17
sk-Counter-r15:0,0×0
nr-RadioBearerConfig2-r15:14 09 28 9F 8F C5 37 4D 83
若收到的RRCConnectionReconfiguration包含nr-SecondaryCellGroupConfig，则终端设备120可以执行NR RRC重配置过程，NR RRC重配置过程如通信标准TS 38.331(f70版本)的条款(clause)5.3.5.3所示。
基于TS 38.331(f70版本)的条款5.3.5.3的规定，若RRC重配置消息包括SCG信息，则终端设备120可以按照TS 38.331(f70版本)的条款5.3.5.5的规定执行SCG的小区组配置。
在添加SCG之前，终端设备120需要确定自己是否支持nr-SecondaryCellGroupConfig中指示的5G带宽。
nr-SecondaryCellGroupConfig中的FrequencyInfoDL字段包含NR小区的频点信息和带宽信息。
FrequencyInfoDL字段的格式如下所示。
Figure PCTCN2021118692-appb-000004
上述字段中，absoluteFrequencySSB表示NR小区的中心频点，即，5G频点。下面给出一个确定5G带宽的示例。
例如，nr-SecondaryCellGroupConfig包含了如下内容：
Figure PCTCN2021118692-appb-000005
Figure PCTCN2021118692-appb-000006
上述内容中，subcarrierSpacing表示子载波间隔，取值为30kHz；carrierBandwidth表示载波带宽，取值51表示载波带宽包括51个资源块(resourceblock，RB)。每个RB包括12个子载波，可以根据51*12*30kHz确定载波带宽为18360kHz，即，nr-SecondaryCellGroupConfig中指示的5G带宽为18.36MHz。
若终端设备120不支持nr-SecondaryCellGroupConfig中指示的5G带宽，则终端设备120可以执行下列步骤。
S220，当终端设备120不支持配置所述SCG时，发送指示信息，所述指示信息用于指示所述SCG发生异常。
终端设备120不支持SCG，可以被解释为：终端设备120无法使用nr-SecondaryCellGroupConfig中指示的5G带宽进行通信，或者，终端设备120的NR能力与网络设备110配置的NR能力不匹配。在此情况下，终端设备120无法配置SCG，因此，终端设备120可以向网络设备110发送指示信息，指示SCG发生异常，即，SCG对应的LTE小区和NR小区的组合匹配失败。
上述指示信息例如是NR SCG失败信息(SCG_FAILURE_INFO_NR)。NR SCG失败信息用于提供UE检测到的与NR SCG失败相关的信息。
NR SCG失败信息的内容如下所示：
Figure PCTCN2021118692-appb-000007
NR SCG失败信息为当前已有的信息，但未应用于通过LTE RRC重配置消息配置NR SCG失败的场景。利用现有的信息指示该场景中SCG发生异常，无需设计新的信息，有利于减小通信复杂度。
网络设备110收到指示信息后，确定终端设备120需要释放SCG，则网络设备110可以向终端设备120发送释放SCG的消息。终端设备120释放SCG后无需再发送4G网络重建请求，从而可以避免4G网络连接频繁重建或减少4G网络连接频繁重建次数，提高网络连接的质量。
下面，结合图3进一步介绍本申请提供的配置SCG的方法。
S301，网络设备110向终端设备120发送LTE RRC重配置消息(RRC_CONN_RECFG)1，该消息携带了待测量的5G频点。
S302，终端设备120完成上述5G频点的测量后，向网络设备110发送测量报告。
S303，网络设备110向终端设备120发送LTE RRC重配置消息(RRC_CONN_RECFG)2，该消息包括LTE配置参数和NR配置参数，该NR配置参数用于配置SCG。
S304，终端设备120确定终端设备120支持的带宽与NR配置参数中的带宽匹配失败，即，终端设备120不支持NR配置参数中的5G带宽。
S305，终端设备120向网络设备110发送LTE RRC重配置完成消息(RRC_CONN_RECFG_CMP)。
S306，终端设备120向网络设备110发送NR SCG失败信息(SCG_FAILURE_INFO_NR)。
S307，终端设备120记录终端设备120支持的带宽与NR配置参数中的带宽匹配失败的次数，当该次数大于等于第一阈值时，确定不再上报SCG的测量报告。
图4示出了一种终端设备120支持的带宽与NR配置参数中的带宽匹配失败的示意图。
网络设备110配置的5G频点位于终端设备120支持的带宽范围内，但是，基于该5G频点配置的5G带宽超出了终端设备120支持的带宽范围。因此，终端设备120支持LTE RRC重配置消息1中配置的5G频点，但是终端设备120支持的带宽与NR配置参数中的带宽匹配失败，该NR小区不能被配置为终端设备120的SCG(即，LTE小区与NR配置参数中指示的5G频点对应的NR小区匹配失败)。
终端设备120可以记录LTE小区和NR小区的组合信息，根据该组合信息确定LTE小区和NR小区匹配失败的次数。该组合信息可以包括：LTE小区的频带ID、频点ID和物理小区ID中的至少一个信息，以及所述NR小区的频带ID、频点ID和物理小区ID中的至少一个信息。
终端设备120还可以根据其它信息确定LTE小区和NR小区匹配失败的次数，例如，终端设备120记录NR参数中的5G频点的ID和网络设备110所属的公共陆地移动网(publiclandmobilenetwork，PLMN)的ID，并基于该5G频点的ID和该PLMN的ID确定LTE小区和NR小区匹配失败的次数。本申请对终端设备120确定LTE小区和NR小区的组合匹配失败的次数的具体方式不做限定。
S305、S306和S307可以同时执行，也可以分别执行，当该三个步骤分别执行时，其执行顺序不受限定。
S308，终端设备120启动定时器，等待接收网络设备110发送的SCG释放信息。
上述定时器可以在发送NR SCG失败信息后立刻启动，也可以在发送NR SCG失 败信息后间隔一段时间启动，终端设备可以通过定时器灵活设置等待SCG释放信息的时段。
基于SCG释放消息的接收情况，终端设备120有以下两种可选的处理方式。
处理方式一，定时器超时前接收到SCG释放信息。
S309，终端设备120从网络设备110接收到LTE RRC重配置消息(RRC_CONN_RECFG)，该LTE RRC重配置消息包括SCG释放信息。
S310，终端设备120停止定时器。
处理方式二，定时器超时时未收到SCG释放信息。
S311，定时器超时。
S312，终端设备120向网络设备110发送LTE RRC重建消息，恢复4G网络连接。
终端设备发送指示信息后，网络设备需要一定的时间做出决策，因此，终端设备在目标时间段不发送LTE RRC重建消息可以减小信令开销。若终端设备在目标时段后仍未收到SCG释放消息，则存在网络设备任务繁忙导致未及时做出决策的可能性，终端设备可以向网络设备发送LTE RRC重建消息，尽快恢复4G网络连接，减小SCG发生异常对通信的影响。
导致NR SCG配置失败的原因有多种，因此，网络设备110收到NR SCG失败信息(SCG_FAILURE_INFO_NR)后不能确定NR SCG配置失败的原因是终端设备120是不支持5G带宽，因此，网络设备110可能再次为终端设备配置NR SCG，即，执行S313。
S313，网络设备110向终端设备120发送LTE RRC重配置消息3，该消息携带了待测量的5G频点。该5G频点与LTE RRC重配置消息1中的5G频点相同。
终端设备120可以再次测量该5G频点，并生成测量报告。终端设备120可以根据终端设备120支持的带宽与NR配置参数中的带宽匹配失败的次数确定是否上报该测量报告。若该次数小于第一阈值，则终端设备120可以再次上报5G频点的测量报告；若该次数大于等于第一阈值，则终端设备120确定不再上报5G频点的测量报告。
例如，S304中的匹配失败是第一次出现的匹配失败情况，第一阈值为4，则终端设备120可以再上报两次5G频点的测量报告，即，执行S314。当网络设备110第四次配置终端设备120测量上述5G频点时，网络设备110执行S315，向终端设备120发送LTE RRC重配置消息7，该消息携带了待测量的5G频点，该5G频点与LTE RRC重配置消息1中的5G频点相同。
终端设备120在生成5G频点的测量报告后可以执行下列步骤。
S316，终端设备120在确定该5G频点的测量报告不满足上报条件时，确定不上报该测量报告。
终端设备120在该情况下停止上报测量报告能够避免网络设备110再次配置NR SCG，从而可以避免4G网络连接频繁重建或减少4G网络连接频繁重建次数，提高网络连接的质量。
可选地，当当网络设备110第四次配置终端设备120测量上述5G频点时，终端设备120可以不再测量该5G频点以减小功耗。
