图1是根据一示例性实施例示出的一种网络连接方法的流程图，图2是根据一示例性实施例示出的一种网络连接方法的场景图；该网络连接方法可以用于基站。如图1所示，该网络连接方法包括以下步骤110-130：
在步骤110中，接收终端发送的连接恢复请求消息。
本公开实施例中，终端可以是非活动状态(inactive state)下的终端。其中，该非活动状态是在第五代移动通信技术(5th Generation，简称为5G)网络中引入的一种状态。
在非活动状态下，基站和终端都保存终端的上下文，终端移动性采用小区选择/重选机制，对于一些小数据包业务、处于非活动状态的终端可以直接发送和接收，而无需进入连接态，从而达到降低终端功耗、节省信令开销的目的。
处于非活动状态的终端，当进入一个新的RNA(Radio Access Network based  Notification Area，无线接入网通知区域)、或周期性位置更新而触发RLAU(Radio Access Network Location Area Update，无线接入网位置区域更新)、或收发信令/数据时，都会向基站发送连接恢复请求消息。并且，该连接恢复请求消息用于实现为非活动状态下的终端恢复RRC(Radio Resource Control，无线资源控制协议)连接、或RLAU、或非活动状态下收发信令/数据。
在步骤120中，根据连接恢复请求消息检测到满足至少一种拒绝原因。
本公开实施例中，基站接收到终端发送的连接恢复请求消息后，可能会有一个或多个拒绝原因来拒绝终端。比如：连接恢复请求消息的消息完整性的校验失败、终端请求进入的RNA禁止该终端进入、网络拥塞、无法获取终端上下文且网络拥塞等。
在步骤130中，向终端发送连接恢复拒绝消息，该连接恢复拒绝消息携带有用于指示基站的拒绝原因的原因值。
本公开实施例中，基站拒绝终端时，会通过连接恢复拒绝消息将拒绝原因告知基站。
比如：基站的拒绝原因为连接恢复请求消息的消息完整性的校验失败，用于指示该拒绝原因的原因值为：完整性校验失败。
又比如：基站的拒绝原因为终端请求进入的RNA禁止该终端进入，用于指示该拒绝原因的原因值为：area is not allowed。
又比如：基站的拒绝原因为网络拥塞，用于指示该拒绝原因的原因值为：overload。
又比如：基站的拒绝原因为无法获取终端上下文且网络拥塞，用于指示该拒绝原因的原因值为：no UE context&overload。
在一实例性场景中，如图2所示，包括基站和终端。处于非活动状态的终端，当进入一个新的RNA、或周期性位置更新而触发RLAU、或收发信令/数据时，都会向基站发送连接恢复请求消息；基站接收到终端发送的连接恢复请求消息后，检测到满足一个或多个拒绝原因时，会向终端发送连接恢复拒绝消息，该连接恢复拒绝消息携带有用于指示基站的拒绝原因的原因值。
由上述实施例可见，通过接收终端发送的连接恢复请求消息，当根据连接恢复请求消息检测到满足至少一种拒绝原因时，则向终端发送连接恢复拒绝消息，该连接 恢复拒绝消息携带有用于指示基站的拒绝原因的原因值，使得终端可以根据连接恢复拒绝消息获知基站的拒绝原因，从而避免了出现终端不理解基站的拒绝行为而不能进行正确的操作的情形，提高了网络连接的安全性，还减少了终端的功耗。

第四拒绝原因，所述第四拒绝原因用于表征无法获取终端上下文且网络拥塞。
由上述实施例可见，基站的拒绝原因可以包括第一拒绝原因、第二拒绝原因、第三拒绝原因和第四拒绝原因中的一种或多种，这样终端接收到连接恢复拒绝消息后，可以根据该连接恢复拒绝消息中携带的原因值获知是哪种拒绝原因，便于终端根据不同的拒绝原因执行不同的处理操作，提高了网络连接的效率。
在一实施例中，上述步骤130中，基站向终端发送的连接恢复拒绝消息中还可以包括：
基站指示的终端状态，该终端状态为空闲状态(idle state)或非活动状态。
本公开实施例中，在空闲状态下，基站和终端不保存终端的上下文，处于空闲状态下的终端不可以直接收发数据。并且，基站指示的终端状态是该基站为终端配置的，不管终端当前是哪种状态，当接收到基站指示的终端状态后，都需要将当前状态调整为基站指示的终端状态。
由上述实施例可见，基站向终端发送的连接恢复拒绝消息中还包括基站指示的终端状态，从而实现了终端根据基站的指示调整自身状态，提高了网络连接的可靠性。
在一实施例中，上述步骤130中，基站向终端发送的连接恢复拒绝消息中还可以包括但不限于以下各种信息：
基站指示的等待时间(waitTime)，所述等待时间是终端再次向基站发送连接恢复请求消息之前的时间；和/或

由上述实施例可见，基站向终端发送的连接恢复拒绝消息中还包括一种或多种其他指示信息，便于终端根据接收到的指示信息执行相应的处理操作，从而提高了网络连接的实用性。
图3是根据一示例性实施例示出的一种网络连接方法的流程图，该网络连接方法可以用于终端，如图3所示，该网络连接方法包括以下步骤310-330：
在步骤310中，向基站发送连接恢复请求消息。
本公开实施例中，终端可以是非活动状态下的终端。该终端当进入一个新的RNA、或周期性位置更新而触发RLAU、或收发信令/数据时，将会向基站发送连接恢复请求消息。
在步骤320中，接收基站发送的连接恢复拒绝消息，该连接恢复拒绝消息携带有用于指示基站的拒绝原因的原因值。
本公开实施例中，终端接收基站发送的连接恢复拒绝消息后，会根据该连接恢复拒绝消息获知基站拒绝了终端请求的恢复连接，并根据该连接恢复拒绝消息携带的原因值获知基站的拒绝原因。
比如：该连接恢复拒绝消息携带的原因值为完整性校验失败，则表明基站的拒绝原因是：连接恢复请求消息的消息完整性的校验失败。
又比如：该连接恢复拒绝消息携带的原因值为area is not allowed，则表明基站的拒绝原因为终端请求进入的RNA禁止该终端进入。
又比如：该连接恢复拒绝消息携带的原因值为overload，则表明基站的拒绝原因为网络拥塞。
又比如：该连接恢复拒绝消息携带的原因值为no UE context&overload，则表明基站的拒绝原因为无法获取终端上下文且网络拥塞。
在步骤330中，根据连接恢复拒绝消息执行对应的处理操作。
本公开实施例中，基站根据连接恢复拒绝消息理解了基站的拒绝行为，则会执行对应的处理操作。
比如：终端获知基站的拒绝原因是网络拥塞，此时终端可以等待一段时间后，再次向终端发送连接恢复请求消息。
由上述实施例可见，通过向基站发送连接恢复请求消息，接收基站发送的连接恢复拒绝消息，该连接恢复拒绝消息携带有用于指示基站的拒绝原因的原因值，根据连接恢复拒绝消息执行对应的处理操作，这样终端可以根据连接恢复拒绝消息获知基站的拒绝原因，从而避免了出现终端不理解基站的拒绝行为而不能进行正确的操作的情形，提高了网络连接的安全性，还减少了终端的功耗。
在一实施例中，上述步骤320中，基站的拒绝原因可以包括但不限于以下各种拒绝原因：

由上述实施例可见，基站的拒绝原因可以包括第一拒绝原因、第二拒绝原因、第三拒绝原因和第四拒绝原因中的一种或多种，这样便于终端根据不同的拒绝原因执行不同的处理操作，提高了网络连接的效率。
在一实施例中，上述步骤330中，若基站发送的连接恢复拒绝消息还包括该基站指示的终端状态，所述终端状态为空闲状态或非活动状态时，可以包括以下处理方式：
将当前状态调整为与基站指示的终端状态相同的状态。
此方式下，终端根据基站的指示调整自身状态。即若基站指示的终端状态为非活动状态，当前状态也为非活动状态，此时终端就可以继续保留在非活动状态；若基站指示的终端状态为空闲状态，当前状态也为非活动状态，此时终端就需要将非活动状态调整为空闲状态。
由上述实施例可见，若基站发送的连接恢复拒绝消息中包括该基站指示的终端状态时，终端可以根据该基站的指示调整自身状态，从而提高了网络连接的可靠性。
在一实施例中，上述步骤330中，若基站的拒绝原因为第一拒绝原因、和/或第四拒绝原因时，可以包括以下处理方式：
将当前状态调整为空闲状态。
此方式下，终端根据默认方式调整自身状态。即只要是基站的拒绝原因中包括上述的第一拒绝原因或第四拒绝原因，此时不需要基站再指示终端状态，而是终端直接将当前状态调整为空闲状态。
由上述实施例可见，终端可以根据基站的拒绝原因为第一拒绝原因、和/或第四拒绝原因时，直接将当前状态调整为空闲状态，而不需要基站指示是哪种终端状态，这样可以节省信令开销。
在一实施例中，上述步骤330中，若基站发送的连接恢复拒绝消息还包括基站指示的RNA信息，该RNA信息包括基站指示的小区或区域时，可以包括以下处理方式：
保存基站指示的RNA信息，并将基站指示的小区或区域设置为禁止用于小区重选的小区或区域。
此方式下，终端可以将基站指示的小区或区域设置为禁止小区或区域，并在小区重选时将这些禁止小区或区域视为不合适小区。
由上述实施例可见，若基站发送的连接恢复拒绝消息中包括基站指示的RNA信息，该RNA信息包括基站指示的小区或区域，这样终端可以保存基站指示的RNA信息，并将基站指示的小区或区域设置为禁止用于小区重选的小区或区域，从而避免了小区重选时使用基站指示的小区或区域，提高了小区重选的可靠性。
在一实施例中，上述步骤330中，若基站发送的连接恢复拒绝消息还包括基站 指示的等待时间，该等待时间是所述终端再次向所述基站发送连接恢复请求消息之前的时间时，可以包括以下处理方式：
在基站指示的等待时间到达后，再次向基站发送连接恢复请求消息。
由上述实施例可见，若基站发送的连接恢复拒绝消息中包括基站指示的等待时间，这样终端可以在基站指示的等待时间到达后，再次向基站发送连接恢复请求消息，从而实现了基站控制终端发送连接恢复请求消息的频率，避免了终端不停的发送连接恢复请求消息也达不到恢复连接的目的，避免了终端资源的大量浪费，降低了终端的功耗。
在一实施例中，上述步骤330中，可以包括以下处理方式：
当对连接恢复拒绝消息的消息完整性的校验失败、和/或对连接恢复拒绝消息的解密失败时，则删除该连接恢复拒绝消息，并保持当前状态为非活动状态。
此方式下，终端还可以指示本地NAS(Non-Access Stratum，非接入层)完整性校验失败，还可以继续等待基站消息，或者重新向基站发送连接恢复请求消息。
由上述实施例可见，当对连接恢复拒绝消息的消息完整性的校验失败、和/或对连接恢复拒绝消息的解密失败时，可以删除该连接恢复拒绝消息，并保持当前状态为非活动状态，这样便于终端重新向基站发送连接恢复请求消息，提高了网络连接的效率。
在一实施例中，上述步骤330中，还可以包括以下处理方式：
在将当前状态调整为空闲状态后，向本地NAS发送通知信息，所述通知信息包括当前状态为空闲状态，和用于指示所述基站的拒绝原因的原因值。
此方式下，当终端回到空闲状态后，会向本地NAS发送通知信息；当终端保存在非活动状态时，不需要向本地NAS发送通知信息。
由上述实施例可见，在将当前状态调整为空闲状态后，向本地NAS发送通知信息，该通知信息包括当前状态为空闲状态，和用于指示基站的拒绝原因的原因值，这样本地NAS可以根据通知消息获知当前状态为空闲状态，以及基站的拒绝原因，从而提高了网络连接的可靠性。
