下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的连接建立方法进行详细地说明。
本申请各实施例针对非地面网络(Non-Terrestrial Networks，NTN)小区内的终端(User Equipment，UE)在相同或相近的时间发生服务链路(service link)，和/或，馈线链路(feeder link)切换过程，导致目标小区拥塞的问题，提供一种解决方案，能 够使得终端接收源网络侧设备提供的切换辅助信息；其中，切换辅助信息包括目标小区的配置信息；终端基于切换辅助信息与目标小区建立连接，使得终端在发生service link和/或feeder link切换的场景下，能够避免在大量同时或相近的时机接入目标小区而导致拥塞的问题。为了便于更加清晰地理解本申请各实施例，首先对一些相关的技术知识进行如下介绍。
一、非地面网络(Non-terrestrial networks，NTN)
图2是本申请实施例可应用的非地面网络的示意图，如图2所示，典型的NTN部署场景包括终端(User Equipment，UE)21、卫星(Satellite)(或无人空中系统平台(Unmanned Aerial System platform，UAS platform))22和网关(Gateway)(或基站)23。在R17版本中，终端21、基站23以及核心网设备均部署在地面上，终端21和基站23之间的通信数据经由空中的卫星22进行中转。相对于地面网络(Terrestrial Networks，TN)系统，基于卫星的非地面通信系统具有更为广阔的覆盖范围，并且NTN小区服务的用户数量也会远大于TN小区。
如图2所示，终端21和卫星22之间的链路称为服务链路(即service link)，卫星22和网关(或基站)23之间的链路称为馈线链路(即feeder link)，终端21处于卫星所覆盖的卫星视场或无人空中系统平台(Field of view the satellite or UAS platform),卫星视场包括多个波束脚印(Beam foot print)。在某些场景下(如低轨卫星(Low Earth Orbit Satellite，LEO))，由于卫星移动，会发生service link，和/或，feeder link的切换。对于service link切换，小区内的所有终端的服务卫星需要从一颗卫星切换为另外一颗卫星。对于feeder link切换，某一卫星需要从一个网关(或基站)切换到另外一个网关(或基站)。在R17版本中，无论是service link切换还是feeder link切换场景，对于NTN小区的所有终端来说，都需要执行小区切换过程。
图3是本申请实施例提供的连接建立方法的流程示意图之一，如图3所示，该方法包括步骤301-步骤302；其中：
步骤301，终端接收源网络侧设备提供的切换辅助信息；其中，所述切换辅助信息包括目标小区的配置信息；

2)一个时间触发事件信息。

3)一个时间触发事件信息及时间延迟参数；所述时间延迟参数用于延迟所述终端与所述目标小区建立连接的时机。
具体地，时间触发事件信息用于指示终端与目标小区建立连接的时机，时机表示时间信息，例如，[t1，t2]；时间延迟参数用于延迟终端与目标小区发起连接建立过程的时机。
需要说明的是，在上述示例中，主要针对是一个目标小区对应时间触发事件信息的关联关系。具体地，切换辅助信息可以包含多个目标小区的配置信息。对于每一个目标小区的配置信息，所述切换辅助信息还可以包含至少两个时间触发事件信息，或者一个时间触发事件信息，或者一个时间触发事件信息及时间延迟参数。上述描述同样适用于后续实施例，将不再赘述。
实际中，在终端接收到源网络侧设备提供的切换辅助信息之后，终端可以根据切换辅助信息，在时间触发事件信息指示的与目标小区建立连接的时机，与目标小区建立连接。
本申请实施例提供的连接建立方法中，终端通过接收源网络侧设备提供的切换辅助信息；其中，切换辅助信息包括目标小区的配置信息；终端基于切换辅助信息与目标小区建立连接，使得终端在发生service link和/或feeder link切换的场景下，特别是在目标小区配置信息是源网络侧设备通过广播或组播方式提供给源服务小区的终端的情况下，能够避免在大量终端同时或以相近的时机接入目标小区而导致拥塞的问题。
可选地，上述步骤301的具体实现方式包括：
所述终端接收所述源网络侧设备通过广播或组播发送的所述切换辅助信息。

2)所述终端随机基于业务需求从所述至少两个时间触发事件信息中选择目标时间触发事件信息。
具体地，终端可以随机基于业务需求从至少两个时间触发事件信息中选择一个目标时间触发事件信息；例如，终端在具有低中断时间需求业务的情况下，选择与最早的切换时间关联的时间触发事件信息。示例性的，目标小区cell_1关联了两个时间触发事件信息，例如，其中一个时间触发事件信息为[T1，T3]，表示在[T1，T3]时间范围内终端可以与目标小区建立连接，另外一个时间触发事件信息为[T2，T3](T1<T2<T3)，表示在[T2，T3]时间范围内终端可以与目标小区建立连接。终端在具有低中断时间需求业务的情况下，可以选择时间触发事件信息[T1，T3]，以便于尽早发起与目标小区的连接建立过程。反之，终端在没有低中断时间需求业务的情况下，可以选择时间触发事件信息[T2，T3]，以便于延迟发起与目标小区的连接建立过程。基于此，不同的终端可以根据各自的业务需求选择对应的时间触发事件信息，从而避免所有的终端都在相同的时间或以相近的时间发起与目标小区的连接建立过程，进而造成目标小区拥塞。

可选地，所述终端基于第二规则与所述目标小区建立连接，包括：
所述终端基于第二规则及所述时间触发事件信息对应的第一时长与所述目标小区建立连接。
具体地，终端可以根据第二规则及时间触发事件信息对应的第一时长，与目标小区建立连接。例如，时间触发事件信息为[t1，t2]，则时间触发事件信息对应的第一时长为(t2-t1)，第一数值范围为[0，t2-t1]，则终端在[0，t2-t1]内随机或随机等概率的选择一个第一目标值Ta，终端基于第一目标值Ta，延迟终端与目标小区建立连接的时机，则终端与目标小区建立连接的时机为[t1+Ta，t2]。
本申请实施例提供的连接建立方法中，在切换辅助信息包括一个以上时间触发事件信息的情况下，终端基于第二规则及时间触发事件信息对应的第一时长，与目标小区建立连接，使得终端在发生service link和/或feeder link切换的场景下，基于时间触发事件信息离散化终端与目标小区建立连接的时机，能够避免在大量同时或相近的时机接入目标小区而导致拥塞的问题。
3、切换辅助信息包括一个时间触发事件信息及时间延迟参数

具体地，终端可以根据第三目标值及时间触发事件信息对应的第二时长，计算第三目标值及时间触发事件信息对应的第二时长的乘积，得到所述第四目标值。例如，第三目标值为1/2，时间触发事件信息为[t1，t2]，第二时长为(t2-t1)，则第三目标值及时间触发事件信息对应的第二时长的乘积为(t2-t1)/2，即第四目标值为(t2-t1)/2。
可选地，所述终端基于第三规则与所述目标小区建立连接包括以下任意一项：
1)所述终端基于所述第二目标值，延迟所述终端与所述目标小区建立连接的时机。
具体地，终端根据在第二数值范围内选择第二目标值，可以延迟终端与目标小区建立连接的时机。例如，时间触发事件信息为[t1，t2]，时间延迟参数为T2，终端随机从[0，T2]范围内选择的第二目标值为Tb，则终端与目标小区建立连接的时机为[t1+Tb，t2]，即终端与目标小区建立连接的时机由[t1，t2]延迟至[t1+Tb，t2]。
2)所述终端基于所述目标延迟参数，延迟所述终端与所述目标小区建立连接的时机。
具体地，终端根据从至少两个时间延迟参数中选择的目标时间延迟参数值，可以延迟终端与目标小区建立连接的时机。例如，时间触发事件信息为[t1，t2]，Ta、Tb和Tc等3个时间延迟参数中选择的目标时间延迟参数值为Tc，则终端与目标小区建立连接的时机为[t1+Tc，t2]，即终端与目标小区建立连接的时机由[t1，t2]延迟至[t1+Tc，t2]。
