具体实施方式
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作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。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据 在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”一般表示前后关联对象是一种“或”的关系。
首先，对本申请实施例中涉及到的相应术语进行介绍；
双连接(Dual Connectivity，DC)，即为UE提供两个网络节点(接入网网元)的资源，其中一个网络节点称为主节点(Master Node，MN)，另一个称为辅节点(Secondary Node，SN)。在每个网络节点，使用了载波聚合技术(Carrier Aggregation，CA)，即为用户终端(User Equipment，UE)配置由该节点控制的一系列服务小区，也称小区组(cell group)。主节点MN控制的为主小区组(Master Cell Group，MCG)，辅节点SN控制的为辅小区组(Secondary Cell Group，SCG)。每个小区组都包含一个特殊小区(Special Cell，SpCell)和一系列辅小区(Secondary Cell，Scell)。在MCG中特殊小区称为主小区(Primary Cell，PCell)，在SCG中特殊小区称为主辅小区(Primary Secondary Cell，PSCell)。在一个小区组中SpCell使用主载波，而其他辅小区使用辅载波，一个小区组内的资源调度由SpCell进行。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。然而，以下描述出于示例目的描述了新空口(New Radio，NR)系统，并且在以下大部分描述中使用NR术语，尽管这些技术也可应用于NR系统应用以外的应用，如第6代(6 th Generation，6G)通信系统。
图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11，网络侧设备12和网络侧设备13。其中，终端11也可以称作终端设备或者用户终端(User Equipment，UE)，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备(VUE)、行人终端(PUE)等终端侧设备，可穿戴式设备包括：手环、耳机、眼镜等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12和网络侧设备13两者之间具有主辅的区别，即主网络侧设备12和辅网络侧设备13，反之亦然，网络侧设备12和网络侧设备13可以是基站，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点、发送接收点(Transmitting Receiving Point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的挂起辅小区组的方法进行详细地说明。
请参见2，图2是本申请实施例的挂起辅小区组的方法流程图一，如图2所示，该方法的步骤包括：
步骤S202，第一节点接收第二节点发送的请求消息，其中，请求消息用于请求挂起用户终端的辅小区组；
步骤S204，在第一节点向第二节点发送用于指示确定挂起辅小区组的确认消息的情况下，第一节点触发目标节点挂起用户终端的辅小区组；其中，目标节点为用于控制辅小区组的节点；目标节点为第一节点或第二节点。
通过上述步骤S202和步骤S204可知，在第二节点向第一节点发送请求 挂起SCG的请求消息后，如果第一节点确定挂起SCG，则触发用于控制SCG的目标节点挂起SCG，从而实现对SCG的挂起，以解决如何实现挂起SCG的问题。
需要说明的是，在第一节点为主节点MN的情况下，第二节点为辅节点SN；或，在第一节点为辅节点SN的情况下，第二节点为主节点MN。
在本申请实施例中优选为辅节点对SCG进行控制，因此，在第一节点为MN且第二节点为SN的情况下，上述步骤S202和步骤S204为：MN接收SN发送的请求消息；在MN向SN发送用于指示确定挂起辅小区组的确认消息的情况下，MN触发SN挂起用户终端的辅小区组。
在此情况下，MN向SN发送的请求消息可以是携带第一指示信息的SCG挂起请求(SCG Suspend Request)，也可以是携带第一指示信息的S-NODE MODIFICATION REQUEST(辅节点修改请求)消息，其中，第一指示信息用于指示辅节点挂起。在实际应用场景中，根据实际需求进行相应的选择。
在本申请实施例中的另一个可选实施方式中，在第一节点为SN且第二节点为MN的情况下，该步骤S202和步骤S204可以是：通过SN接收MN发送的请求消息；在SN向MN发送用于指示确定挂起辅小区组的确认消息的情况下，SN挂起用户终端的辅小区组。也就是说，在这种情况下，第一节点和目标节点均为SN，即该触发挂起的过程则是由SN直接挂起用户终端的辅小区组。
在此情况下，该请求消息可以为携带挂起SCG信息的S-NODE MODIFICATION REQUIRED(辅节点修改需求)消息，也可以为携带挂起SCG信息的SCG挂起请求消息。在实际应用场景中，根据实际需求进行相应的选择。
可选地，在本申请实施例中在所述第一节点确定挂起辅小区组的情况下，本申请实施例的方法还可以包括：
步骤S206，第一节点向用户终端发送重配置消息，其中，重配置消息中携带有辅小区组挂起的信息；
步骤S208，第一节点接收用户终端响应于配置消息反馈的重配置完成消息。
在第一节点为MN且第二节点为SN的情况下，上述步骤S206和与第一节点向所述第二节点发送用于指示确定挂起辅小区组的确认消息的步骤没有先后顺序；也就是说，可以是MN向用户终端发送重配置消息后，MN再向SN发送用于指示确定挂起辅小区组的确认消息，也可以是MN向SN发送用于指示确定挂起辅小区组的确认消息后，MN再向用户终端发送重配置消息。
在第一节点为SN且第二节点为MN的情况下，上述步骤S206和与第一节点向所述第二节点发送用于指示确定挂起辅小区组的确认消息的步骤没有先后顺序；即可以是SN向用户终端发送重配置消息后，SN再向MN发送用于指示确定挂起辅小区组的确认消息，也可以是SN向MN发送用于指示确定挂起辅小区组的确认消息后，SN再向用户终端发送重配置消息。但是，在这种情况下，步骤S204中SN挂起用户终端的辅小区组步骤是在步骤S208之后，即在SN接收用户终端响应于配置消息反馈的重配置完成消息之后。
下面结合本申请实施例的具体实施方式，对本申请进行举例说明；
在第一节点为SN，第二节点为MN的情况下，如图3所示，本申请实施例的具体实施方式的步骤包括：
步骤S11，MN发起SCG suspend,向SN发送SCG挂起请求(SCG Suspend Request)；
其中，SCG Suspend Requests消息的另一种实现方式可以为携带第一指示信息的S-NODE MODIFICATION REQUEST消息，其中，第一指示信息用于指示辅节点挂起。
步骤S12，SN确定挂起SCG；
步骤S13，SN向MN发送SCG挂起确认消息；
需要说明的是，SN也可以拒绝SCG挂起，SN给MN发送拒绝消息(SCG Suspend REFUSE),过程结束。
步骤S14，SN向UE发送RRC重配置消息(RRC(Connection)Reconfiguration)；其中，RRC重配置消息携带SCG Suspend信息。
步骤S15，UE接收RRC重配置消息(RRC(Connection)Reconfiguration)，向SN发送RRC重配置完成消息(RRC(Connection)ReconfigurationComplete)。UE挂起SCG。
步骤S16，SN挂起UE的SCG。
需要说明的是，对于上述图3中的步骤S13和步骤S14可以调换顺序，即步骤S13可以在步骤S14之前或之后，但步骤S16一定在步骤S15之后。
在第一节MN，第二节点SN的情况下，如图4所示，本申请实施例的具体实施方式的步骤包括：
步骤S21，SN发起SCG suspend,向MN发送SCG挂起请求(SCG Suspend Request)；
其中SCG Suspend Requests消息的另一种实现方式可以为携带第一指示信息的S-NODE MODIFICATION REQUIRED消息，其中，第一指示信息用于指示辅节点挂起。
步骤S22，MN确定挂起SCG；MN向SN发送SCG挂起确认消息；
需要说明的是，在MN拒绝SCG挂起的情况下，MN给SN发送拒绝消息(SCG Suspend REFUSE)，流程结束。
步骤S23，SN挂起SCG。
步骤S24，MN向UE发送RRC重配置消息(RRC(Connection)Reconfiguration)；其中，RRC重配置消息携带SCG Suspend信息。
步骤S25，UE接收RRC重配置消息(RRC(Connection)Reconfiguration)，向MN发送RRC重配置完成消息(RRC(Connection)ReconfigurationComplete)。UE挂起SCG。
对于上述图4中的步骤S22和S24不限制先后顺序，即步骤S22可以在S24之前或之后，但是S25是S24的后续步骤。
本申请实施例还提供了一种挂起辅小区组的方法，请参见图5，图5是本申请实施例的挂起辅小区组的方法流程图二，如图5所示，该方法的步骤包括：
步骤S502，在第一节点确定挂起辅小区组的情况下，第一节点向第二节点发送指示消息，其中，指示消息用于指示将挂起用户终端的辅小区组的决定通知给第二节点；
步骤S504，第一节点触发目标节点挂起用户终端的辅小区组；其中，目标节点为用于控制辅小区组的节点；目标节点为第一节点或第二节点。
通过上述步骤S502和步骤S504可知，第一节点可以自己决定是否挂起SCG，当决定要挂起SCG时，只需要将决定通知给第二节点即可，最后触发用于控制SCG的节点来挂起用户终端的SCG。该目标节点可以是第一节点也可以是第二节点。
需要说明的是，本申请实施例中在第一节点为主节点的情况下，第二节点为辅节点；或，在第一节点为辅节点的情况下，第二节点为主节点。
因此，在第一节点为MN且第二节点为SN的情况下，上述步骤S502和步骤S504可以是：在MN决定挂起SCG的情况下，MN向SN发送指示消息；该由于目标节点是控制SCG的节点，因此是MN触发SN挂起用户终端的辅小区组。
在第一节点为SN且第二节点为MN的情况下，上述步骤S502和步骤S504可以是：在SN决定挂起SCG的情况下，SN向MN发送指示消息；SN挂起用户终端的辅小区组；即SN自己决定挂起SCG以及自己执行挂起SCG的操作。
可选地，在所述第一节点确定挂起辅小区组的情况下，本申请实施例的方法还可以包括：
步骤S506，第一节点向用户终端向用户终端发送重配置消息，其中，重配置消息中携带有辅小区组挂起的信息；第一节点和第二节点为用户终端的控制节点；
步骤S508，第一节点接收用户终端响应于配置消息反馈的重配置完成消息。
在第一节点为MN且第二节点为SN的情况下，上述步骤S506和步骤S504的顺序并不限定，即步骤S506可以在步骤S504之前，也可以是步骤S506在步骤S504之后。在第一节点为SN且第二节点为MN的情况下，也是一样的，上述步骤S506和步骤S504的顺序并不限定。
下面结合本申请实施例的具体实施方式，对本申请进行举例说明；
在第一节点为MN，第二节点SN的情况下，如图6所示，本申请实施例的具体实施方式的步骤包括：
步骤S31，MN确定挂起SCG。
步骤S32，MN向SN发送SCG挂起指示消息(SCG Suspend Indication)。所述SCG挂起指示消息表示MN将挂起UE的SCG。
步骤S33，SN挂起SCG；
步骤S34，MN向UE发送RRC重配置消息(RRC(Connection)Reconfiguration)。其中，RRC重配置消息携带SCG Suspend信息。
步骤S35，UE接收RRC重配置消息(RRC(Connection)Reconfiguration)，向MN发送RRC重配置完成消息(RRC(Connection)ReconfigurationComplete)。UE挂起SCG。
对于上述图6中的步骤S32和S34其执行的顺序是不限定的，即步骤S32可在S34之前或之后；但步骤S33是S32的后续步骤，步骤S35是S34的后续步骤。
在第一节点为SN，第二节点MN的情况下，如图7所示，本申请实施例的具体实施方式的步骤包括：
步骤S41，SN确定挂起SCG。
步骤S42，SN向MN发送SCG挂起指示消息(SCG Suspend Indication)。所述SCG挂起指示消息表示SN将挂起UE的SCG。
步骤S43，SN向UE发送RRC重配置消息(RRC(Connection)Reconfiguration)；其中，RRC重配置消息携带SCG Suspend信息。
步骤S44，UE接收RRC重配置消息(RRC(Connection)Reconfiguration)，向SN发送RRC重配置完成消息(RRC(Connection)ReconfigurationComplete)。UE挂起SCG。
步骤S45，SN接收到RRC重配置完成消息后，挂起SCG。
对于图7中的步骤S42和S43，其执行的先后顺序是可以调换的，即步骤S42可以在S43之前或之后。
需要说明的是，本申请实施例提供的挂起辅小区组方法，执行主体可以为挂起辅小区组装置，或者，该挂起辅小区组装置中的用于执行挂起辅小区组方法的控制模块。本申请实施例中以挂起辅小区组装置执行挂起辅小区组方法为例，说明本申请实施例提供的挂起辅小区组的装置。
