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，所描述的实施例仅仅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做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。
图1是根据本公开的实施例示出的一种业务挂起方法的示意流程图。本实施例所示的业务挂起方法可以适用于基站，所述基站包括但不限于4G基站、5G基站、6G基站。所述基站可以与作为用户设备的终端进行通信，还可以与核心网通信，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。
在一个实施例中，所述终端可以是后续任一实施例所述挂起指示方法所适用的终端。所述核心网可以是后续任一实施例所述业务挂起方法所适用的核心网。
在一个实施例中，在终端中可以设置有多个SIM卡，所述SIM卡包括但不限于USIM卡、eSIM卡。多个SIM卡可以输入相同运营商网络，也可以属于不同运用商网络。以下实施例主要针对多个SIM卡包括第一SIM卡和第二SIM卡的情况进行示例性描述，其中，第一SIM卡和第二SIM卡并非特指终端中的某个SIM卡，而是指终端中任意两个不同的SIM卡。
如图1所示，所述业务挂起方法可以包括以下步骤：
在步骤S101中，接收多卡终端中第一SIM卡离开连接态(具体可以是主动离开连接态)的指示信息；
在步骤S102中，根据所述基站的本地配置确定将所述第一SIM卡对应业务挂 起(suspend)。
在一个实施例中，终端在使用第一SIM卡进行通信的过程中，若需要使用第二SIM卡进行通信，会出现第一SIM卡和第二SIM卡通信冲突的问题。
在这种情况下，终端可以确定是否需要第一SIM卡离开连接态，若确定需要第一SIM卡离开连接态，可以直接向基站发送(例如通过接入层发送)指示信息，以告知基站第一SIM卡需要离开连接态，也即基站可以直接接收第一SIM卡发送的所述指示信息；终端也可以将指示信息发送(例如通过非接入层发送)至核心网，然后由核心网将指示信息发送至基站，也即基站可以接收核心网发送的所述指示信息，从而间接地接收到来自终端的指示信息。
在相关技术中，为了针对用户面业务的挂起，仅适用于CIoT，也即仅支持消费物联网中的用户面业务的挂起，而针对普通终端和多卡终端，则并没有提出用户面业务挂起的机制。例如对于多卡终端而言，在第一SIM卡离开网络后，由于没有将第一SIM卡对应业务挂起，那么需要使用第一SIM卡继续通信时，就需要重新进入连接态，消耗资源较多。
本实施例中的终端可以是非CIoT的终端。根据本公开的实施例，基站可以根据指示信息确定终端中的第一SIM卡需要离开连接态，进而根据基站的本地配置确定将第一SIM卡对应业务挂起，从而针对普通终端和多卡终端而言，也能够在终端中的SIM卡需要离开连接态时，将SIM卡对应业务挂起，从而在第一SIM卡需要继续进行通信时，例如第二SIM卡完成通信后，可以快速地与基站交互用户面数据，而无需重新进入连接态。
在一个实施例中，第一SIM卡离开连接态，可以是指第一SIM卡进入非连接态，非连接态的类型包括但不限于空闲(idle)态、非激活(inactive)态。基站不仅可以根据的本地配置确定将第一SIM卡对应业务挂起，还可以在此基础上考虑第一SIM卡进入的非连接态的类型，例如在第一SIM卡需要进入非激活态，本地配置的策略为能够挂起业务时，将第一SIM卡对应业务挂起，在第一SIM卡需要进入空闲态，本地配置的策略为能够挂起业务时，将第一SIM卡对应业务释放。
需要说明的是，基站确定将第一SIM卡对应业务挂起，包括两种情况，一种是确定挂起，另一种是确定不挂起，确定不挂起的方式之一可以是确定释放。
在一个实施例中，在确定挂起的情况下，基站可以向核心网发送将第一SIM卡 对应业务挂起的请求，核心网可以根据核心网的本地配置将第一SIM卡对应业务挂起。
例如核心网在确定将第一SIM卡对应业务挂起的情况下，可以向基站发送挂起响应，以指示基站将第一SIM卡对应业务挂起。基站可以保存第一SIM卡对应业务的上下文，并向终端发送无线资源控制层(Radio Resource Control，RRC)连接挂起信令，指示终端第一SIM卡对应业务挂起，并在该信令中可以携带业务恢复标识(Resume ID)，以便终端基于业务恢复标识恢复挂起的业务，其中，终端可以在处于非连接态的情况下恢复挂起的业务。
在一个实施例中，在确定释放的情况下，基站可以向核心网发送将第一SIM卡对应业务释放的请求，核心网可以根据核心网的本地配置将第一SIM卡对应业务释放。
例如核心网在确定将第一SIM卡对应业务释放的情况下，可以向基站发送释放指示，以指示基站将第一SIM卡对应业务释放。基站可以删除第一SIM卡对应业务的上下文，并向终端发送无线资源控制层(Radio Resource Control，RRC)连接释放信令，指示终端第一SIM卡对应业务释放，终端若需要通过第一SIM卡进行通信，就需要重新通过第一SIM卡与基站建立RRC连接。
需要说明的是，基站与核心网之间的通信，可以通过核心网与基站间的N2接口实现。
图2是根据本公开的实施例示出的另一种业务挂起方法的示意流程图。如图2所示，在一些实施例中，所述根据所述基站的本地配置确定将所述第一SIM卡对应业务挂起包括：
在步骤S201中，响应于所述基站本地配置的可用资源大于第一资源阈值，向核心网发送将所述第一SIM卡对应业务挂起的请求；
在步骤S202中，响应于所述基站本地配置的可用资源小于第一资源阈值，向核心网发送将所述第一SIM卡对应业务释放的请求。
在一个实施例中，若将第一SIM卡对应业务挂起，需要保留该业务的上下文，这需要占用一些存储资源，进一步地，为了确保终端能够在非连接态快速地与基站交互用户面数据，可以为终端预留一些资源以与终端通信，这需要占用一些时频资源。
本实施例可以先确定基站的本地配置中，可用资源是否充足，可用资源包括但不限于存储资源、时频资源。在可用资源充足时，例如大于第一资源阈值时，可以确定将第一SIM卡对应业务挂起，向核心网发送将第一SIM卡对应业务挂起的请求；在 可用资源不足时，例如小于第一资源阈值时，可以确定不将第一SIM卡对应业务挂起，而将第一SIM卡对应业务释放，那么可以向核心网发送将第一SIM卡对应业务释放的请求。
图3是根据本公开的实施例示出的又一种业务挂起方法的示意流程图。如图3所示，在一些实施例中，所述根据所述基站的本地配置确定将所述第一SIM卡对应业务挂起包括：
在步骤S301中，响应于所述基站本地配置的策略为能够挂起业务，向核心网发送将所述第一SIM卡对应业务挂起的请求；
在步骤S302中，响应于所述基站本地配置的策略为不能挂起业务，向核心网发送将所述第一SIM卡对应业务释放的请求。
在一个实施例中，不同基站本地配置的策略可以不同，并且同一基站在不同时刻本地配置的策略也可以不同。在基站本地配置的策略为能够挂起业务时，可以向核心网发送将第一SIM卡对应业务挂起的请求；在基站本地配置的策略为不能能挂起业务时，可以确定不将第一SIM卡对应业务挂起，而将第一SIM卡对应业务释放，那么可以向核心网发送将第一SIM卡对应业务释放的请求。
图4是根据本公开的实施例示出的又一种业务挂起方法的示意流程图。如图4所示，在一些实施例中，所述根据所述基站的本地配置确定将所述第一SIM卡对应业务挂起包括：
在步骤S401中，响应于所述基站本地配置的可用资源大于第一资源阈值，且所述基站本地配置的策略为能够挂起业务，向核心网发送将所述第一SIM卡对应业务挂起的请求；
在步骤S402中，响应于所述基站本地配置的可用资源小于第一资源阈值，或所述基站本地配置的策略为不能挂起业务，向核心网发送将所述第一SIM卡对应业务释放的请求。
在一个实施例中，可以综合考虑基站本地的配置和本地配置的策略。例如在可用资源充足时，例如大于第一资源阈值时，且基站本地配置的策略为能够挂起业务，可以确定将第一SIM卡对应业务挂起，向核心网发送将第一SIM卡对应业务挂起的请求；例如在可用资源不足时，例如小于第一资源阈值时，或者基站本地配置的策略为不能挂起业务，可以确定不将第一SIM卡对应业务挂起，向核心网发送将第一SIM卡 对应业务释放的请求。
在一个实施例中，第一资源阈值可以与终端发送的指示信息相关联，也即在指示信息用于指示基站，终端中的第一SIM卡离开连接态时，终端根据第一资源阈值与可用资源进行比较，来确定是否将第一SIM卡对应业务挂起，而在指示信息是用于指示其他内容(例如第一SIM卡处于阴影衰落)时，终端可以通过其他方式确定是否将第一SIM卡对应业务挂起。
图5是根据本公开的实施例示出的又一种业务挂起方法的示意流程图。如图5所示，在一些实施例中，所述方法还包括：
在步骤S501中，向核心网发送将所述第一SIM卡对应业务的挂起请求，其中，所述挂起请求包含挂起所述第一SIM卡对应业务的原因为多卡终端离开。
在相关技术中，虽然基站可以向核心网发送针对某个业务的挂起请求，但是一般只会指示粗略的操作类型(Operation type)信息为用户面挂起(UP suspend)，核心网据此难以准确确定将第一SIM卡业务挂起的原因。
根据本实施例，基站可以在发送给核心网的挂起请求中，携带挂起第一SIM卡对应业务的原因，例如可以携带在操作类型的信息中携带该原因，从而使得核心网可以确定基站请求挂起第一SIM卡对应业务的原因为第一SIM卡离开连接态，以便核心网可以根据该原因准确地确定是否将第一SIM卡对应业务挂起。
需要说明的是，在本公开的所有实施例中，原因为多卡终端离开，具体原因例如可以是多卡终端中的第一SIM卡离开连接态。
图6是根据本公开的实施例示出的又一种业务挂起方法的示意流程图。如图6所示，在一些实施例中，所述方法还包括：
在步骤S601中，确定所述第一SIM卡离开连接态的持续时长；
在步骤S602中，向所述核心网发送所述持续时长。
在一个实施例中，终端在确定第一SIM卡需要离开连接态时，可以预测第一SIM卡需要离开连接态的持续时长，例如终端可以确定第二SIM卡需要通信的时长，根据该时长确定(例如将该时长或者该时长加上另一个时长作为持续时长)第一SIM卡离开连接态的持续时长，进而终端可以将预测的持续时长发送给基站，基站可以进一步将该持续时长发送至核心网，以便核心网根据该持续时长确定何时将第一SIM卡 对应业务释放，例如核心网可以在将第一SIM卡对应业务挂起的时长达到持续时长时，将第一SIM卡对应业务释放。
图7是根据本公开的实施例示出的一种业务挂起方法的示意流程图。本实施例所示的业务挂起方法可以适用于核心网，所述核心网包括但不限于4G核心网、5G核心网、6G核心网。所述核心网可以与作为用户设备的终端进行通信，还可以与基站通信，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。
在一个实施例中，所述终端可以是后续任一实施例所述挂起指示方法所适用的终端。所述基站可以是上述任一实施例所述业务挂起方法所适用的基站。
如图7所示，所述业务挂起方法可以包括以下步骤：
在步骤S701中，接收基站发送的挂起多卡终端中第一SIM卡对应业务的挂起请求，其中，所述挂起请求包含挂起所述第一SIM卡对应业务的原因为多卡终端离开；
在步骤S702中，根据所述原因以及核心网的本地配置确定将所述第一SIM卡对应业务挂起。
在相关技术中，虽然基站可以向核心网发送针对某个业务的挂起请求，但是一般只会指示粗略的操作类型信息为用户面挂起，核心网据此难以准确确定将第一SIM卡业务挂起的原因。
根据本实施例，基站可以在发送给核心网的挂起请求中，携带挂起第一SIM卡对应业务的原因，例如可以携带在操作类型的信息中携带该原因，从而使得核心网可以确定基站请求挂起第一SIM卡对应业务的原因为第一SIM卡离开连接态，以便核心网可以根据该原因以及核心网的本地配置，准确地确定是否将第一SIM卡对应业务挂起。
图8是根据本公开的实施例示出的另一种业务挂起方法的示意流程图。如图8所示，在一些实施例中，所述根据所述原因以及核心网的本地配置确定将所述第一SIM卡对应业务挂起包括：
在步骤S801中，响应于所述核心网本地配置的可用资源大于第二资源阈值，将所述第一SIM卡对应业务挂起，其中，所述第二资源阈值与所述原因相关联；
在步骤S802中，响应于所述核心网本地配置的可用资源小于第二资源阈值， 将所述第一SIM卡对应业务释放。
在一个实施例中，第二资源阈值可以与所述原因相关联，也即在原因为多卡终端离开时，核心网根据第二资源阈值与可用资源进行比较，来确定是否将第一SIM卡对应业务挂起，而在所述原因为其他原因(例如第一SIM卡处于阴影衰落)，或者在挂起请求中没有所述原因时，核心网可以通过其他方式确定是否将第一SIM卡对应业务挂起。
在一个实施例中，若将第一SIM卡对应业务挂起，需要保留该业务的上下文，这需要占用一些存储资源，进一步地，为了确保终端能够在非连接态快速地与核心网交互用户面数据，可以为终端预留一些资源以与终端通信，这需要占用一些时频资源。
本实施例可以先确定核心网的本地配置中，可用资源是否充足，可用资源包括但不限于存储资源、时频资源。在可用资源充足时，例如大于第二资源阈值时，可以确定将第一SIM卡对应业务挂起；在可用资源不足时，例如小于第二资源阈值时，可以确定不将第一SIM卡对应业务挂起，而将第一SIM卡对应业务释放，删除第一SIM卡对应业务的上下文。
图9是根据本公开的实施例示出的又一种业务挂起方法的示意流程图。如图9所示，在一些实施例中，所述根据所述原因以及核心网的本地配置确定将所述第一SIM卡对应业务挂起包括：
在步骤S901中，响应于所述核心网本地配置的策略为能够挂起业务，将所述第一SIM卡对应业务挂起；
在步骤S902中，响应于所述核心网本地配置的策略为不能挂起业务，将所述第一SIM卡对应业务释放。
在一个实施例中，不同核心网本地配置的策略可以不同，并且同一核心网在不同时刻本地配置的策略也可以不同。在核心网本地配置的策略为能够挂起业务时，将第一SIM卡对应业务挂起；在核心网本地配置的策略为不能能挂起业务时，可以不将第一SIM卡对应业务挂起，而将第一SIM卡对应业务释放，删除第一SIM卡对应业务的上下文。
图10是根据本公开的实施例示出的又一种业务挂起方法的示意流程图。如图10所示，在一些实施例中，所述根据所述基站核心网的配置和/或策略确定将所述第一SIM卡对应业务挂起包括：
在步骤S1001中，响应于所述核心网本地配置的可用资源大于第二资源阈值，且所述核心网本地配置的策略为能够挂起业务，将所述第一SIM卡对应业务挂起，其中，所述第二资源阈值与所述原因相关联；
在步骤S1002中，响应于所述核心网本地配置的可用资源小于第二资源阈值，或所述核心网本地配置的策略为不能挂起业务，将所述第一SIM卡对应业务释放。
在一个实施例中，可以综合考虑核心网本地的配置和本地配置的策略。例如在可用资源充足时，例如大于第一资源阈值时，且核心网本地配置的策略为能够挂起业务，可以将第一SIM卡对应业务挂起；例如在可用资源不足时，例如小于第一资源阈值时，或者核心网本地配置的策略为不能挂起业务，可以不将第一SIM卡对应业务挂起，将第一SIM卡对应业务释放的请求，删除第一SIM卡对应业务的上下文。
图11是根据本公开的实施例示出的又一种业务挂起方法的示意流程图。如图11所示，在一些实施例中，所述核心网包括接入和移动管理功能AMF(Access and Mobility Management Function)，以及会话管理功能SMF(Session Management Function)，所述方法还包括：
在步骤S1101中，通过AMF向SMF发送对所述第一SIM卡对应业务的会话管理上下文进行更新的更新请求，其中，所述更新请求包含操作类型为用户面挂起，以及用户面挂起的原因为多卡终端离开；
在步骤S1102中，响应于用户面挂起的原因为多卡终端离开，通过SMF对所述第一SIM卡对应业务的会话管理上下文进行更新。
在一个实施例中，核心网在确定将第一SIM卡挂起时，具体可以通过AMF向SMF发送更新请求，在更新请求中可以包含操作类型为用户面挂起，也即用户面挂起的具体原因为第一SIM卡离开连接态，以使SMF可以根据该原因适当地更新第一SIM卡对应业务的会话管理上下文。
进一步地，SMF还可以向用户面管理功能UPF(User Plane Function)发送N4会话修改请求，通过会话修改请求指示UPF是否将第一SIM卡对应业务挂起，其中，若挂起，UPF可以不释放AN隧道(基站与核心网通信隧道)信息，并缓存第一SIM卡对应业务上下文，若释放，UPF可以释放AN隧道(基站与核心网通信隧道)信息，并删除第一SIM卡对应业务上下文。
图12是根据本公开的实施例示出的又一种业务挂起方法的示意流程图。如图 12所示，在一些实施例中，所述方法还包括：
在步骤S1201中，确定所述第一SIM卡离开连接态的持续时长；
在步骤S1202中，响应于将所述第一SIM卡对应业务挂起的时长达到所述持续时长，将所述第一SIM卡对应业务释放。
在一个实施例中，终端在确定第一SIM卡需要离开连接态时，可以预测第一SIM卡需要离开连接态的持续时长，例如终端可以确定第二SIM卡需要通信的时长，根据该时长确定(例如将该时长或者该时长加上另一个时长作为持续时长)第一SIM卡离开连接态的持续时长，进而终端可以将预测的持续时长发送给基站，基站可以进一步将该持续时长发送至核心网，以便核心网根据该持续时长确定何时将第一SIM卡对应业务释放。
例如核心网可以在将第一SIM卡对应业务挂起的时长达到持续时长时，将第一SIM卡对应业务释放，由于将第一SIM卡对应业务挂起的时长达到持续时长时，第一SIM卡已经不是离开连接态的状态了，例如已经通过随机接入重新回到了连接态，第一SIM卡对应业务的上下文，已经不是核心网所保存的第一SIM卡离开连接态时的上下文，那么继续保存该上下文将会造成存储资源的浪费，因此可以将第一SIM卡对应业务释放，也即将第一SIM卡离开连接态时的第一SIM卡对应业务的上下文删除。
图13是根据本公开的实施例示出的一种挂起指示方法的示意流程图。本实施例所示的挂起指示方法可以适用于终端，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。所述终端可以作为用户设备与基站通信，所述基站包括但不限于4G基站、5G基站、6G基站。
在一个实施例中，所述基站可以是上述任一实施例所述业务挂起方法所适用的基站。所述核心网可以是上述任一实施例所述业务挂起方法所适用的核心网。
在一个实施例中，在终端中可以设置有多个SIM卡，所述SIM卡包括但不限于USIM卡、eSIM卡。多个SIM卡可以输入相同运营商网络，也可以属于不同运用商网络。以下实施例主要针对多个SIM卡包括第一SIM卡和第二SIM卡的情况进行示例性描述，其中，第一SIM卡和第二SIM卡并非特指终端中的某个SIM卡，而是指终端中任意两个不同的SIM卡。

其中，所述指示信息用于指示所述第一SIM卡离开连接态。
根据本公开的实施例，终端在第一SIM卡需要离开连接态时，可以向基站发送指示信息，基站可以根据指示信息确定终端中的第一SIM卡需要离开连接态，进而根据基站的本地配置确定将第一SIM卡对应业务挂起，从而针对普通终端和多卡终端而言，也能够在终端中的SIM卡需要离开连接态时，将SIM卡对应业务挂起，从而在第一SIM卡需要继续进行通信时，例如第二SIM卡完成通信后，可以快速地与基站交互用户面数据，而无需重新进入连接态。
终端还可以向核心网发送指示信息，并且基站还可以在接收到指示信息的情况下向核心网发送挂起请求，从而使得核心网可以确定基站请求挂起第一SIM卡对应业务的原因为第一SIM卡离开连接态，以便核心网可以根据该原因以及核心网的本地配置，准确地确定是否将第一SIM卡对应业务挂起。
图14是根据本公开的实施例示出的另一种挂起指示方法的示意流程图。如图14所示，在一些实施例中，所述方法还包括：
在步骤S1401中，响应于所述终端中第一SIM卡处于连接态时，需要使用第二SIM卡通信，确定所述第一SIM卡需要离开连接态(主动离开连接态)。
在一个实施例中，终端在使用第一SIM卡进行通信的过程中，若需要使用第二SIM卡进行通信，会出现第一SIM卡和第二SIM卡通信冲突的问题，在这种情况下，终端可以确定需要第一SIM卡离开连接态。

在步骤S1501中，预测所述第一SIM卡离开连接态的持续时长；
在步骤S1502中，将所述持续时长发送至所述基站和/或所述核心网。
在一个实施例中，终端在确定第一SIM卡需要离开连接态时，可以预测第一SIM卡需要离开连接态的持续时长，例如终端可以确定第二SIM卡需要通信的时长，根据该时长确定(例如将该时长或者该时长加上另一个时长作为持续时长)第一SIM 卡离开连接态的持续时长，进而终端可以将预测的持续时长发送给基站，基站可以进一步将该持续时长发送至核心网，以便核心网根据该持续时长确定何时将第一SIM卡对应业务释放，例如核心网可以在将第一SIM卡对应业务挂起的时长达到持续时长时，将第一SIM卡对应业务释放。
图16是根据本公开的实施例示出的基站与核心网的交互示意图。
如图16所示，基站在接收到终端发送的第一SIM卡离开连接态的指示信息后，可以基站的本地配置确定将第一SIM卡对应业务挂起；
若确定将第一SIM卡对应业务挂起，可以向核心网的AMF发送挂起请求，在挂起请求中携带有挂起第一SIM卡对应业务的原因为第一SIM卡离开连接态，还可以进一步携带有第一SIM离开连接态的持续时长；
核心网的AMF可以向核心网的SMF发送对第一SIM卡对应业务的会话管理上下文进行更新的更新请求，在请求中携带有更新请求包含操作类型为用户面挂起，以及用户面挂起的原因为多卡终端离开，还可以进一步携带有第一SIM离开连接态的持续时长；
核心网的SMF可以确定是否将第一SIM卡对应业务释放，并据此指示核心网的UPF是否释放AN隧道，以及是否缓存第一SIM卡对应业务的上下文；
SMF在更新第一SIM卡对应业务的会话管理上下文后，可以向AMF返回上下文更新响应；
AMF可以向基站发送挂起请求的响应；
基站可以向终端发送RRC连接挂起信令，以及业务恢复标识。
