具体实施方式
下面将结合本公开实施例中的附图，对本公开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公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，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，都属于本公开保护的范围。
本申请的说明书和权利要求书中的术语“包括”以及它的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。此外，说明书以及权利要求中使用“和/或”表示所连接对象的至少其中之一，例如A和/或B，表示包含单独A，单独B，以及A和B都存在三种情况。
在本公开实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本公开实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
在对本公开实施例的技术方案进行详细的说明之前，先对终端的双连接应用场景进行简单的介绍。
在双连接应用场景下，终端可以在两个小区组同时建立连接，即，终端可以在主小区组(Master Cell Group，MCG)和辅小区组(Secondary Cell Group，SCG)同时建立连接。其中，MCG包括主小区(Primary Cell，PCell)和辅小区(Secondary Cell，SCell)，SCG包括主辅小区(Primary Secondary Cell，PSCell)和SCell。其中，PCell和PSCell又都可以称为特殊小区(Special Cell，SpCell)。
在双连接应用场景下，存在双连接移动性过程，例如，双连接切换或辅小区组变更(SCG change)。如图1所示，在双连接移动性过程中，终端同时保持源小区和目标小区的连接(如图1中的步骤4)，然后，终端释放源小区的连接而仅保持在目标小区的连接(如图1中的步骤5)。
在双连接移动性过程中，终端可能需要向网络侧上报辅助信息。通常，终端只有在初次有辅助信息上报的时候，或者之前上报的辅助信息的内容发生变更的时候，才会上报辅助信息。目前，对于双连接应用场景中终端如何上报辅助信息，尚没有明确的解决方案。进一步的，对于双连接移动性过程中终端如何上报辅助信息，更加没有明确的解决方案。这使得网络侧设备和终端对于辅助信息的内容无法保持一致，从而会影响双连接应用场景下的通 信性能。
进一步考虑，如果网络侧设备配置了终端可以向源小区和目标小区上报辅助信息，在双连接移动性过程中，若终端在源小区上报了辅助信息，而该辅助信息的内容又没有发生变化，那么终端不会再重复上报该辅助信息内容。而当终端释放源小区的连接而仅保持在目标小区的连接时，将导致目标小区无法获得终端的辅助信息，这将进一步影响双连接应用场景下的通信性能。
鉴于此，为了解决上述问题，本公开实施例提供一种辅助信息上报方法、辅助信息上报配置方法、终端和网络侧设备。
下面结合附图介绍本公开的实施例。本公开提供的实施例可以应用于无线通信系统中。该无线通信系统可以为5G系统，或者演进型长期演进(Evolved Long Term Evolution，eLTE)系统，或者后续演进通信系统。
图2是本公开实施例提供的一种网络系统的结构图，如图2所示，包括终端21、源小区的网络侧设备22和目标小区的网络侧设备23，其中，终端21可以是移动通信设备，例如：可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等，需要说明的是，在本公开实施例中并不限定终端21的具体类型。上述源小区的网络侧设备22和目标小区的网络侧设备23可以是5G网络侧设备(例如：gNB、5G NR NB)，或者可以是4G网络侧设备(例如：eNB)，或者可以是3G网络侧设备(例如：NB)，或者后续演进通信系统中的网络侧设备，等等，需要说明的是，在本公开实施例中并不限定源小区的网络侧设备22和目标小区的网络侧设备23的具体类型。
图3是本公开实施例提供的一种辅助信息上报方法的流程图，应用于图2所示的网络系统。如图3所示，该方法包括以下步骤：
步骤301：源小区的网络侧设备或目标小区的网络侧设备向终端发送控制信息。
其中，网络侧设备通过上述控制信息配置终端在双连接移动性过程中向目标小区上报辅助信息，该双连接移动性过程中，终端同时保持源小区和目标小区的连接。该网络侧设备包括源小区的网络侧设备和目标小区的网络侧 设备中的至少之一。
步骤302：终端接收网络侧设备发送的控制信息。
步骤303：在双连接移动性过程中，终端向目标小区上报终端的辅助信息。
步骤304：目标小区的网络侧设备接收终端的辅助信息。
这里，终端向目标小区上报终端的辅助信息，可以理解为，终端向目标小区的网络侧设备上报终端的辅助信息。相应的，终端若向源小区上报终端的辅助信息，则可以理解为，终端向源小区的网络侧设备上报终端的辅助信息，
本公开实施例中，网络侧设备通过向终端发送控制信息，用于配置终端在双连接移动性过程中向目标小区上报辅助信息，这样，终端在双连接移动性过程中，可向目标小区上报辅助信息，确保了双连接移动性过程中目标小区获得辅助信息的优势，从而避免了双连接移动性过程中终端向源小区上报辅助信息而导致目标小区无法获得辅助信息的情况发生。这样，有利于使网络侧设备和终端对于辅助信息的内容保持一致，有利于提高双连接应用场景下的通信性能。
图4是本公开实施例提供的一种辅助信息上报方法的流程图。如图4所示，辅助信息上报方法，应用于终端，该方法包括以下步骤：
步骤401：在双连接移动性过程中，向目标小区上报所述终端的辅助信息。
其中，在双连接移动性过程中，终端同时保持源小区和上述目标小区的连接，双连接移动性过程包括双连接切换或辅小区组变更。在双连接移动性过程之后，终端可释放与源小区的连接，而仅保持与目标小区的连接。这里，源小区可以为包括多个小区的小区组，即源小区组，目标小区也可以为包括多个小区的小区组，即目标小区组。
上述双连接移动性过程的结束条件可以包括以下任意一种：
终端释放了与源小区的连接；
终端与目标小区的接入过程成功，例如，终端和目标PCell的随机接入过程成功，或者，对于采用非随机接入的移动性过程(如，RACHless切换)， 终端发送上行信息后接收到网络侧设备的确认消息；
双连接切换失败，例如，对于双连接切换过程T304超时；
辅小区组变更失败，例如，对于双连接SCG变更过程T307超时；
双连接失败，例如，源连接和目标连接同时发生无线链路失败。
需要说明的是，在双连接移动性过程之后，终端仅保持与目标小区的连接，终端的辅助信息也可以在双连接移动性过程之后上报给目标小区。
终端的辅助信息可包括如下的至少一项：
多媒体广播组播(Multimedia Broadcast/Multicast Service，MBMS)业务的兴趣信息，例如，终端当前的PCell广播了SIB15，则终端允许上报MBMSInterestIndication(MBMS兴趣指示)消息；其中，SIB15是指终端定位信息；
终端的自干扰辅助信息，例如，InDeviceCoexIndication(设备Coex指示)消息；
终端的节能喜好信息，例如，UEAssistanceInformation(终端辅助信息)消息中携带的节能喜好信息指示；
副链路(Sidelink)终端提供的辅助信息，例如，SidelinkUEInformation(副链路终端信息)消息；
终端对于数据收发延迟的容忍余量信息，例如，UEAssistanceInformation消息中携带的delayBudgetReport(延迟预算报告)信息；
终端的过热指示辅助信息，例如，UEAssistanceInformation消息中携带的过热指示辅助信息。
终端在上报上述辅助信息中的某些辅助信息，例如，过热指示辅助信息之后，会启动这些辅助信息对应的禁止定时器，在该禁止定时器运行期间，终端不能再上报这些辅助信息。
该步骤中，终端可通过目标小区的无线承载1(Signaling Radio Bearer 1，SRB1)向目标小区上报终端的辅助信息。其中，SRB1用于发送专用控制信道(Dedicated Control Channel，DCCH)逻辑信道的无线资源控制(Radio Resource Control，RRC)消息，例如，连接重配置消息等。SRB1也可以用于在SRB2建立前发送非接入层(Non-Access Stratum，NAS)消息。
本公开实施例中，终端在双连接移动性过程中，向目标小区上报辅助信息，这样，确保了双连接移动性过程中目标小区获得辅助信息的优势，从而避免了双连接移动性过程中终端向源小区上报辅助信息而导致目标小区无法获得辅助信息的情况发生。这样，有利于使网络侧设备和终端对于辅助信息的内容保持一致，有利于提高双连接应用场景下的通信性能。
可选的，在所述双连接移动性过程中，所述方法还包括：
禁止向所述源小区上报所述终端的辅助信息；或者，
向所述源小区上报所述终端的辅助信息。
本公开实施例中，终端除了向目标小区上报终端的辅助信息之外，还可以禁止向源小区上报终端的辅助信息，也可以向源小区上报终端的辅助信息。这样，终端上报辅助信息的方式包括如下三种：其一，终端向目标小区上报终端的辅助信息；其二，终端向目标小区上报终端的辅助信息，以及终端禁止向源小区上报终端的辅助信息；其三，终端向目标小区上报终端的辅助信息，以及终端向源小区上报终端的辅助信息。
以下分别对各种可行的辅助信息上报方式或辅助信息上报策略进行具体说明。
作为一种可选的实施方式，若协议约定所述终端在所述双连接移动性过程中禁止向所述源小区上报辅助信息，则所述终端向所述目标小区上报所述终端的辅助信息，且禁止向所述源小区上报所述终端的辅助信息。
额外的，网络侧设备可以指示所述终端在所述源小区和所述目标小区上报辅助信息。具体的，网络侧设备可通过向终端发送控制信息，例如双连接移动性过程控制信息，以指示终端可以在源小区和目标小区上报辅助信息，例如，指示终端可以同时在源小区和目标小区上报辅助信息。
终端在接收到网络侧设备发送的双连接移动性过程控制信息之后，可根据双连接移动性过程控制信息，触发双连接移动性过程，例如，双连接切换。
该实施方式中，虽然终端被配置了可以在源小区和目标小区上报辅助信息，但协议约定在双连接移动性过程中，终端禁止向源小区上报辅助信息，例如，终端在触发给源小区的辅助信息的时候，认为给源小区的辅助信息对应的禁止定时器正在运行，从而不向源小区上报辅助信息。
该实施方式中，终端遵从协议的约定，终端在双连接移动性过程中，禁止给源小区上报终端的辅助信息，只给目标小区上报终端的辅助信息。
进一步的，所述方法还包括：
若所述终端在所述目标小区的连接发生失败，且所述终端保持所述源小区的连接，则向所述源小区上报所述终端的辅助信息。
该实施方式中，可通过协议约定，对于目标小区连接发生失败的时候，如果终端的源小区连接仍然能正常工作，且终端有辅助信息上报，则终端允许向源小区上报辅助信息。这样，在目标小区连接失败的情况下，也能够使网络侧设备和终端对于辅助信息的内容保持一致，有利于提高双连接应用场景下的通信性能。
作为另一种可选的实施方式，若网络侧设备指示所述终端关闭所述源小区的辅助信息的上报，且在所述目标小区上报辅助信息，则所述终端向所述目标小区上报所述终端的辅助信息，且禁止向所述源小区上报所述终端的辅助信息。
其中，网络侧设备可通过向终端发送控制信息，例如双连接移动性过程控制信息，以指示终端关闭源小区的辅助信息的上报，且指示终端在目标小区上报辅助信息。例如，网络侧设备可在双连接移动性过程控制信息中的源小区(或源小区组)配置信息中的otherConfig(其他配置)中，关闭源小区的辅助信息的上报，或者，不配置源小区的辅助信息的上报。
终端在接收到网络侧设备发送的双连接移动性过程控制信息之后，可根据双连接移动性过程控制信息，触发双连接移动性过程，例如，双连接切换。
上述网络侧设备既可以是源小区的网络侧设备，也可以是目标小区的网络侧设备，即，上述网络侧设备可包括所述源小区的网络侧设备和所述目标小区的网络侧设备中的至少之一。
若上述网络侧设备为源小区的网络侧设备，则源小区的网络侧设备(或称源节点)给目标小区的网络侧设备(或称目标节点)发送的双连接移动性过程准备消息中，指示关闭源小区的辅助信息的上报。例如，在源小区的网络侧设备给目标小区的网络侧设备发送的切换准备消息中，源小区的网络侧设备在源小区的配置信息中关闭源小区的辅助信息的上报。
若上述网络侧设备为目标小区的网络侧设备，则目标小区的网络侧设备给源小区的网络侧设备发送的双连接移动性过程确认消息中，指示关闭源小区的辅助信息的上报。例如，在目标小区的网络侧设备给源小区的网络侧设备发送的切换准备确认消息中，目标小区的网络侧设备指示关闭源小区的辅助信息的上报。
该实施方式中，根据网络侧设备的控制信息，终端在双连接移动性过程中，不给源小区上报终端的辅助信息，只给目标小区上报终端的辅助信息。
进一步的，所述方法还包括：
若所述终端在所述目标小区的连接发生失败，且所述终端保持所述源小区的连接，则向所述源小区上报所述终端的辅助信息。
该实施方式中，可通过协议约定，对于目标小区连接发生失败的时候，如果终端的源小区连接仍然能正常工作，且终端有辅助信息上报，则终端允许向源小区上报辅助信息。这样，在目标小区连接失败的情况下，也能够使网络侧设备和终端对于辅助信息的内容保持一致，有利于提高双连接应用场景下的通信性能。
作为另一种可选的实施方式，向所述目标小区上报所述终端的辅助信息之前，所述方法还包括：
删除所述源小区的第一SRB，所述第一SRB用于上报所述终端的辅助信息；
建立所述目标小区的第二SRB，所述第二SRB用于上报所述终端的辅助信息。
其中，网络侧设备可向终端发送控制信息，例如双连接移动性过程控制信息。在该双连接移动性过程控制信息中，网络侧设备可以给终端发送对应的RRC消息发送通道配置信息。该RRC消息发送通道配置信息可包括用于目标小区(或目标小区组)的SRB1和SRB2配置信息。
该RRC消息发送通道配置信息还可以包括用于指示删除源小区(或源小区组)SRB1和SRB2的配置信息。进一步的，如果源小区(或源小区组)之前包括SRB3，则该RRC消息发送通道配置信息还可以包括用于指示删除源小区(或源小区组)SRB3的配置信息。进一步的，对于接入的多个目标小区 同时包括MCG和SCG，该RRC消息发送通道配置信息还可以包括用于指示给SCG配置SRB3的配置信息。
其中，SRB1用于发送DCCH逻辑信道的RRC消息，例如，连接重配置消息等，SRB1也可以用于在SRB2建立前发送NAS消息，终端可通过SRB1向网络侧设备上报终端的辅助信息。SRB2用于通过DCCH逻辑信道发送NAS消息，SRB2比SRB1优先级低，可以在接入网安全性激活后被配置，终端可通过SRB2向网络侧设备上报终端的辅助信息。SRB3用于通过DCCH逻辑信道发送SCG的RRC消息。
上述源小区的第一SRB可以理解为源小区的SRB1、SRB2和SRB3中的至少之一，上述目标小区的第二SRB可以理解为目标小区的SRB1、SRB2和SRB3中的至少之一。
该实施方式中，网络侧设备通过RRC消息发送通道配置信息既包括用于目标小区的SRB1和SRB2配置信息，还包括用于指示删除源小区SRB1和SRB2的配置信息。终端可根据网络侧设备的配置信息，触发双连接移动性过程，对于源小区(或源小区组)，终端删除源小区(或源小区组)的SRB1和SRB2。对于目标小区(或目标小区组)，终端建立SRB1和SRB2。如果源小区(或源小区组)之前包括SRB3，则终端也可删除源小区(或源小区组)的SRB3。此外，对于接入的多个目标小区同时包括MCG和SCG，如果网络侧设备给SCG配置了SRB3，则终端可建立对于SCG的SRB3。
其中，对于目标小区(或目标小区组)的SRB1、SRB2和SRB3，终端可根据其各自的功能在目标小区(或目标小区组)发送和接收对应的RRC消息，例如，发送终端的辅助信息。对于源小区(或源小区组)，由于没有包括SRB1、SRB2和SRB3，则终端无法将该终端的辅助信息上报给源小区(或源小区组)。
需要说明的是，上述通过RRC消息发送通道配置信息的相关配置也可以通过协议约定。
该实施方式中，终端通过删除源小区的第一SRB，并建立目标小区的第二SRB，使得终端无法向源小区上报终端的辅助信息，而只向目标小区上报终端的辅助信息。
进一步的，向所述目标小区上报所述终端的辅助信息之前，所述方法还 包括：
建立所述源小区的第三SRB，所述第三SRB用于上报所述终端在所述目标小区连接失败的信息和/或所述第三SRB不用于上报所述终端的辅助信息。
其中，网络侧设备可向终端发送控制信息，例如双连接移动性过程控制信息。在该双连接移动性过程控制信息中，网络侧设备可以给终端发送对应的RRC消息发送通道配置信息。该RRC消息发送通道配置信息可包括用于源小区(或源小区组)的SRBx(如SRB4)配置信息，其中，该“SRBx配置信息”包括该SRBx对应的逻辑信道标识(如逻辑信道标识4)。
额外的，可通过协议规定源小区(或源小区组)的SRBx能发送的消息类型包括用于指示终端在目标小区连接失败的信息(简称“目标小区连接失败信息”)，例如，终端在目标小区的连接发生了失败，终端将该目标小区连接失败信息通过源小区的SRBx上报给网络侧设备。
额外的，还可通过协议规定源小区(或源小区组)的SRBx能发送的消息类型不包括终端的辅助信息。或者说，终端不能通过源小区的SRBx向源小区发送终端的辅助信息。
上述源小区的第三SRB可以理解为源小区的SRBx。
其中，上述目标小区连接失败信息可包括以下至少一种：
目标小区切换失败信息；
目标小区无线链路失败信息；
目标小区RRC消息配置失败信息；
目标小区完整性验证失败信息。
进一步的，若所述终端在所述目标小区连接失败，所述方法还包括：
通过所述第三SRB向所述源小区上报所述终端在所述目标小区连接失败的信息。
作为另一种可选的实施方式，向所述目标小区上报所述终端的辅助信息之前，所述方法还包括：
保留所述源小区的第四SRB，在所述双连接移动性过程之前，所述第四SRB用于上报所述终端的辅助信息，在所述双连接移动性过程中，所述第四SRB用于上报所述终端在所述目标小区连接失败的信息和/或所述第四SRB 不用于上报所述终端的辅助信息；
建立所述目标小区的第五SRB，所述第五SRB用于上报所述终端的辅助信息。
其中，网络侧设备可向终端发送控制信息，例如双连接移动性过程控制信息。在该双连接移动性过程控制信息中，网络侧设备可以给终端发送对应的RRC消息发送通道配置信息。该RRC消息发送通道配置信息可包括用于目标小区(或目标小区组)的SRB1和SRB2配置信息。进一步的，对于接入的多个目标小区同时包括MCG和SCG，该RRC消息发送通道配置信息还可以包括用于指示给SCG配置SRB3的配置信息。
该RRC消息发送通道配置信息还可以包括用于更改源小区(或源小区组)SRB1能发送的消息类型的配置信息，例如，在双连接移动性过程之前，源小区(或源小区组)的SRB1能发送的消息类型包括终端的辅助信息，而在双连接移动性过程中，源小区(或源小区组)的SRB1能发送的消息类型不包括终端的辅助信息。进一步的，源小区(或源小区组)的SRB1能发送的消息类型可包括用于指示终端在目标小区连接失败的信息(简称“目标小区连接失败信息”)。例如，终端在目标小区的连接发生了失败，终端将该目标小区连接失败信息通过源小区的SRB1上报给网络侧设备。
上述源小区的第四SRB可以理解为源小区的SRB1，上述目标小区的第五SRB可以理解为目标小区的SRB1、SRB2和SRB3中的至少之一。
该实施方式中，网络侧设备通过RRC消息发送通道配置信息既包括用于目标小区的SRB1和SRB2配置信息，还包括用于更改源小区(或源小区组)SRB1能发送的消息类型的配置信息。终端可根据网络侧设备的配置信息，触发双连接移动性过程，对于源小区(或源小区组)，终端保留源小区(或源小区组)的SRB1。对于目标小区(或目标小区组)，终端建立SRB1和SRB2。此外，对于接入的多个目标小区同时包括MCG和SCG，如果网络侧设备给SCG配置了SRB3，则终端可建立对于SCG的SRB3。
其中，对于目标小区(或目标小区组)的SRB1、SRB2和SRB3，终端可根据其各自的功能在目标小区(或目标小区组)发送和接收对应的RRC消息，例如，发送终端的辅助信息。对于源小区(或源小区组)，由于源小区(或源 小区组)的SRB1在双连接移动性过程中无法用于上报终端的辅助信息，则终端无法将该终端的辅助信息上报给源小区(或源小区组)。
需要说明的是，上述通过RRC消息发送通道配置信息的相关配置也可以通过协议约定。
该实施方式中，虽然终端保留了源小区的第四SRB，但由于源小区的第四SRB在双连接移动性过程中不用于上报终端的辅助信息，使得终端无法向源小区上报终端的辅助信息。而终端通过建立目标小区的第五SRB，使得终端只向目标小区上报终端的辅助信息。
进一步的，若所述终端在所述目标小区连接失败，所述方法还包括：
通过所述第四SRB向所述源小区上报所述终端在所述目标小区连接失败的信息。
作为另一种可选的实施方式，若网络侧设备指示所述终端在所述源小区和所述目标小区上报辅助信息，则所述终端向所述目标小区和所述源小区上报所述终端的辅助信息。
其中，网络侧设备可通过向终端发送控制信息，例如双连接移动性过程控制信息，以指示终端可以在源小区和目标小区上报辅助信息，例如，指示终端可以同时在源小区和目标小区上报辅助信息。
终端在接收到网络侧设备发送的双连接移动性过程控制信息之后，可根据双连接移动性过程控制信息，触发双连接移动性过程，例如，双连接切换。
该实施方式中，由于终端被配置了可以在源小区和目标小区上报辅助信息，因此，终端既可向目标小区上报终端的辅助信息，也可向源小区上报终端的辅助信息。
其中，终端向目标小区和源小区上报终端的辅助信息，可包括以下两种方式。其一，将所述终端的辅助信息复制生成第一辅助信息和第二辅助信息，向源小区发送第一辅助信息，以及向目标小区发送第二辅助信息。其二，根据源小区的配置信息生成第三辅助信息，向源小区发送所述第三辅助信息，以及，根据目标小区的配置信息生成第四辅助信息，向目标小区发送第四辅助信息。
在第一种方式中，对于每一个触发条件触发的辅助信息上报，终端将辅 助信息生成两份，即，终端将辅助信息复制生成第一辅助信息和第二辅助信息，分别通过源小区和目标小区上报。例如，终端的MBMS兴趣信息内容发生了变更，终端的RRC层触发上报MBMS兴趣信息给网络侧设备，那么，终端的RRC层生成两个MBMS兴趣消息，其中一个MBMS兴趣消息通过源小区连接的SRB1发送，另一个MBMS兴趣消息通过目标小区连接的SRB1发送。该方式中，第一辅助信息和第二辅助信息可以为相同的辅助信息。
在第二种方式中，对于每一个辅助信息上报触发条件，终端的RRC层进行两次RRC辅助信息上报触发，其中一次触发根据源小区的配置信息生成第三辅助信息并上报给源小区，另一次触发根据目标小区的配置信息生成第四辅助信息并上报给目标小区，其中，上述配置信息均为用于触发终端上报辅助信息的配置信息，例如SIB15。例如，终端的MBMS兴趣信息内容发生了变更，终端的RRC层触发上报MBMS兴趣信息给网络侧设备，那么，终端根据源小区的SIB15触发生成一个MBMS兴趣消息并通过源小区连接的SRB1发送，终端根据目标小区的SIB15触发生成另一个MBMS兴趣消息并通过目标小区连接的SRB1发送。该方式中，第三辅助信息和第四辅助信息可以为不同的辅助信息。
额外的，对于第二种方式，第三辅助信息的上报时间与第四辅助信息的上报时间相差预设时间。具体的，可包括以下两种情况：其一，终端在根据源小区的配置信息触发生成第三辅助信息并上报给源小区后，在预设时间以后，终端再根据目标小区的配置信息触发生成第四辅助信息并上报给目标小区。其二，终端在根据目标小区的配置信息触发生成第四辅助信息并上报给目标小区后，在预设时间以后，终端再根据源小区的配置信息触发生成第三辅助信息并上报给源小区。
例如，终端在源小区触发辅助信息上报，在触发或发送该源小区辅助信息后，过了1秒钟以后，终端在目标小区触发辅助信息上报。
其中，上述预设时间可以通过网络侧设备配置或通过协议约定。
综合上述各实施方式，终端在双连接移动性过程中，向目标小区上报辅助信息，这样，确保了双连接移动性过程中目标小区获得辅助信息的优势，从而避免了双连接移动性过程中终端向源小区上报辅助信息而导致目标小区 无法获得辅助信息的情况发生。这样，有利于使网络侧设备和终端对于辅助信息的内容保持一致，有利于提高双连接应用场景下的通信性能。
