Description

一种转换连接的控制方法及其装置 技术领域
本公开涉及通信技术领域，尤其涉及一种转换连接的控制方法及其装置。
背景技术
随着无线通信技术的发展，越来越多的终端设备可以支持多卡模式。对于支持多卡模式的终端设备，其可以有多种不同的处理方式，比如可以为双卡单待、双卡双待双通、双卡双待双通等等，而这些处理方式通常是基于厂商实现的。
通常，当多卡终端设备在和第一***进行通信时，可能需要经常对第二***进行监听寻呼、测量、读取***消息等等。从而，可能会对第一***的性能造成影响。若不对第二***进行监听寻呼、测量、读取***消息等等操作，则可能无法与第二***建立业务连接。另外，当多卡终端设备接收到第二***的寻呼消息时，还需要确定是否需要对该寻呼进行回应，如果多卡终端设备一直不回应第二***的寻呼消息，则第二***会一直对该终端设备进行寻呼，直到达到最大次数。这不仅会浪费信令资源，而且可能会触发第二***的误操作。
由此，如何保证多卡终端设备的可靠使用，显得至关重要。

下面结合附图对本公开所提供的转换连接的控制方法及其装置进行详细地介绍。
请参见图2，图2是本公开实施例提供的一种转换连接的控制方法的流程示意图,该方法由接入网设备执行。如图2所示，该方法可以包括但不限于如下步骤：
步骤21，向终端设备发送第一指示信息，其中，第一指示信息用于向终端设备指示转换连接配置，终端设备中包括至少两个用户身份识别模块。
其中，转换连接配置，可以为用于指示终端设备断开与接入网设备连接的配置信息。
另外，用户身份识别模块(subscriber identity module，SIM)，也称为SIM卡，或者也可以为全球用户身份识别模块(universal subscriber identity module，USIM),其可以表征终端设备与不同接入网设备进行通信时的身份信息。
通常，即使终端设备中有多个SIM卡，终端设备在某一时刻也只能和一个SIM卡对应的接入网设备进行通信，而无法同时和另外的SIM卡对应的其他接入网设备进行通信。
相应的，终端设备在和某一SIM卡对应的接入网设备进行通信时，可能需要经常对另外的SIM卡对应的其他接入网设备进行监听寻呼、测量、读取***消息等等。从而，可能会对当前通信的接入网设备的性能造成影响。若不对其他接入网设备进行监听寻呼、测量、读取***消息等等操作，则可能无法与其他接入网设备建立业务连接，从而不仅会造成通信资源浪费，可能也会影响通信传输的正常进行。
本公开实施例中，对于有多个SIM卡的终端设备，接入网设备可以向该终端设备发送指示转换连接配置的第一指示信息，以使终端设备可以根据第一指示信息，获知转换连接配置，并基于该转换连接配置进行转换连接。从而既保证了不会对当前连接的接入网设备的通信传输造成影响，又避免了其他接入网业务的失败，提高了多卡终端设备的可靠性。
可选的，第一指示信息可以指示终端设备断开与接入网设备连接的时长。
比如，接入网设备向终端设备发送的第一指示信息中指示终端设备可以与接入网设备断开连接的时长为3毫秒(ms)。从而，终端设备，即可在有业务需求时，断开与当前的接入网设备的连接，并把断开连接的时长控制在3ms内。
可选的，第一指示信息可以指示终端设备断开与接入网设备连接的时间图样(time patteen)。
其中，时间图样，可以反映终端设备在不同时段或者不同时刻与接入网设备断开连接的情况，本公开对此不做限定。
比如，协议约定或者接入网设备配置，终端设备在接收到第一指示信息的时刻起，可以根据需求，按照时间图样断开与接入网设备的连接等等，本公开对此不做限定。
可选的，时间图样中可以包括多个时间对。
其中，每个时间对中可以包括两个时刻，两个时刻可以分别表征一次断开连接的断开时刻及恢复连接的时刻。比如，断开时刻为t1，恢复连接时刻为t2，则时间对可以表示为(t1，t2)等等，本公开对此不做限定。
可选的，各个时间对中的断开时刻与连接时刻间的时间间隔可以相同。
比如，时间图样中包括三个时间对，各个时间对中的断开时刻与连接时刻间的时间间隔相同，均为T，则三个时间对可以分别表示为(t1，t1+T)、(t2，t2+T)、(t3，t3+T)。从而，终端设备在有 业务需求时，可以在t1时刻断开与接入网设备的连接，并在t1+T时刻恢复与接入网设备的连接；或者也可以在t2时刻断开与接入网设备的连接，并在t2+T时刻恢复与接入网设备的连接；或者也可以在t3时刻断开与接入网设备的连接，并在t3+T时刻恢复与接入网设备的连接等等。本公开对此不做限定。
可选的，各个时间对中的断开时刻与连接时刻间的时间间隔也可以不同。
比如，时间图样中的三个时间对，分别为(t1，t1+2ms)、(t2，t2+5ms)、(t3，t3+7ms)。从而，终端设备在有业务需求时，可以在t1时刻断开与接入网设备的连接，并在t1+2ms的时刻恢复与接入网设备的连接；或者也可以在t2时刻断开与接入网设备的连接，并在t2+5ms的时刻恢复与接入网设备的连接；或者也可以在t3时刻断开与接入网设备的连接，并在t3+7ms的时刻恢复与接入网设备的连接等等。本公开对此不做限定。
可选的，时间图样中可以包括多个时间对，各相邻的两个时间对中的断开时刻间的时间间隔可以相同。
比如，时间对1、时间对2、时间对3和时间对4顺序排列，时间对1中的断开时刻为t1时刻，时间对2中的断开时刻为t1+2T时刻，时间对3中的断开时刻为t1+4T时刻，时间对4中的断开时刻为t1+6T时刻。从而，终端设备在有业务需求时，可以在t1时刻断开与接入网设备的连接；或者也可以在t1+2T时刻断开与接入网设备的连接；或者也可以在t1+4T时刻断开与接入网设备的连接；或者也可以在t1+6T时刻断开与接入网设备的连接等等。本公开对此不做限定。
可选的，时间图样中可以包括多个时间对，各相邻的两个时间对中的断开时刻间的时间间隔也可以不同。
比如，时间对1、时间对2、时间对3和时间对4顺序排列，时间对1中的断开时刻为t1时刻，时间对2中的断开时刻为t1+T时刻，时间对3中的断开时刻为t1+6T时刻，时间对4中的断开时刻为t1+8T时刻。从而，终端设备在有业务需求时，可以在t1时刻断开与接入网设备的连接；或者也可以在t1+T时刻断开与接入网设备的连接；或者也可以在t1+6T时刻断开与接入网设备的连接；或者也可以在t1+8T时刻断开与接入网设备的连接等等。本公开对此不做限定。
可选的，时间图样中可以包括多个时间对，各相邻的两个时间对中的连接时刻间的时间间隔可以相同。
比如，时间对1、时间对2和时间对3顺序排列，时间对1中的连接时刻为t2时刻，时间对2中的连接时刻为t2+T时刻，时间对3中的连接时刻为t2+2T时刻。从而，终端设备在有业务需求时，可以在t2时刻恢复与接入网设备的连接；也可以在t2+T时刻恢复与接入网设备的连接；或者也可以在t2+2T时刻恢复与接入网设备的连接等等。本公开对此不做限定。
可选的，时间图样中可以包括多个时间对，各相邻的两个时间对中的连接时刻间的时间间隔也可以不同。
比如，时间对1、时间对2、时间对3和时间对4顺序排列，时间对1中的连接时刻为t3时刻，时间对2中的连接时刻为t3+3T时刻，时间对3中的连接时刻为t3+5T时刻，时间对4中的连接时刻为t3+9T时刻。从而，终端设备在有业务需求时，可以在t3时刻恢复与接入网设备的连接；或者也可以在t3+3T时刻恢复与接入网设备的连接；或者也可以在t3+5T时刻恢复与接入网设备的连接；或者也可以在t3+9T时刻恢复与接入网设备的连接等等。本公开对此不做限定。
可选的，第一指示信息可以指示终端设备断开与接入网设备连接的触发事件。
其中，触发事件，可以有多种，比如可以为寻呼监听、测量、读取***消息等等，本公开对此不做限定。
比如，第一指示信息指示终端设备断开与接入网设备连接的触发事件为寻呼监听。则终端设备接收到该第一指示信息后，即可在有寻呼监听需求时，断开与接入网设备的连接等等，本公开对此不做限定。
可选的，第一指示信息可以指示终端设备断开与接入网设备连接的触发事件及每个触发事件对应的断开时长。
比如，第一指示信息指示终端设备断开与接入网设备连接的触发事件为寻呼监听、测量，寻呼监听对应的断开时长为1秒(s)、测量对应的断开时长为20ms。则终端设备接收到该第一指示信息后，即可在有寻呼监听需求时，断开与当前的接入网设备的连接，并把断开连接的时长控制在1s内，或者，也可以在有测量需求时，断开与当前的接入网设备的连接，并把断开连接的时长控制在20ms内。
可选的，第一指示信息可以指示终端设备断开与接入网设备连接的触发事件及每个触发事件对应的断开时间图样。
比如，第一指示信息指示终端设备断开与接入网设备连接的触发事件分别为寻呼监听和测量，且寻呼监听对应的断开时间图样为：5ms、10ms、12ms，测量对应的断开时间图样为3ms、7ms、15ms。若终端设备接收该第一指示信息的时刻为t时刻，则终端设备有寻呼监听需求时，可以在(t+5)ms的时刻， 或者在(t+10)ms的时刻，或者在(t+12)ms的时刻，断开与接入网设备的连接。或者，终端设备有测量需求时，可以在(t+3)ms的时刻，或者在(t+7)ms的时刻，或者在(t+15)ms的时刻，断开与接入网设备的连接。
可选的，第一指示信息可以指示终端设备断开与接入网设备连接的触发事件及每个触发事件对应的断开时间间隔。
比如，第一指示信息指示终端设备断开与接入网设备连接的触发事件分别为寻呼监听和读取***消息，且寻呼监听对应的时间间隔为5ms,读取***消息对应的时间间隔为7ms。即终端设备在进行寻呼监听时，每两次断开与接入网设备连接的时刻间的时间间隔为5ms。或者，终端设备在进行读取***消息时，每两次断开与接入网设备连接的时刻间的时间间隔为7ms。从而终端设备在接收到该第一指示信息后，在有寻呼监听需求时，可以根据该寻呼监听对应的时间间隔，断开与接入网设备的连接。或者在有读取***消息需求时，可以根据该读取***消息对应的时间间隔，断开与接入网设备的连接。
需要说明的是，上述示例只是举例说明，不能作为对本公开实施中第一指示信息等的限定。
可以理解的是，第一指示信息可以包括上述一种，或者也可以包括多种，本公开对此不做限定。
可选的，接入网设备也可以通过RRC消息，向终端设备发送第一指示信息，此处不再赘述。
可选的，RRC消息可以为RRC重配置(RRC reconfiguration)消息，或者也可以为RRC连接重配置(RRC connection reconfiguration)消息等等，本公开对此不做限定。
通过实施本公开实施例，接入网设备可以向终端设备发送第一指示信息，以向终端设备指示转换连接配置。由此，终端设备可以根据网络设备的指示断开与接入网设备的连接，从而既保证了不会对当前连接的接入网设备的通信传输造成影响，又避免了其他接入网业务的失败，提高了多卡终端设备的可靠性。
请参见图3，图3是本公开实施例提供的一种转换连接的控制方法的流程示意图,该方法由接入网设备执行。如图3所示，该方法可以包括但不限于如下步骤：
步骤31，通过RRC消息，向终端设备发送第一指示信息，其中，第一指示信息用于向终端设备指示N个转换连接配置，终端设备中包括至少两个用户身份识别模块，其中，N可以为大于1的正整数。
比如，协议约定：可以在RRC消息中增加特定的比特(bit)位，通过增加的bit位以表征转换连接配置。从而接入网设备可以通过RRC消息，向终端设备发送第一指示信息，以使终端设备在接收到接入网设备发送的第一指示信息之后，按照协议约定，根据特定bit位的取值，获知转换连接配置等等，本公开对此不做限定。
可选的，RRC消息可以为RRC reconfiguration消息，或者也可以为RRC connection reconfiguration消息等等，本公开对此不做限定。
需要说明的是，第一指示信息中包括的内容及具体实现方式，可以参照本公开其他各实施例的说明，此处不再赘述。
步骤32，向终端设备发送第二指示信息，其中，第二指示信息用于激活至少一种转换连接配置。
比如说，第一指示信息指示的转换连接配置为：终端设备断开与接入网设备连接的时长为5ms，以及终端设备断开与接入网设备连接的触发事件为：寻呼监听。且第二指示信息指示终端设备激活断开与接入网设备连接的时长。则终端设备在接收到第二指示信息后，可以将与接入网设备断开连接的时长控制在5ms内。
需要说明的是，上述示例只是举例说明，不能作为对本公开实施中第一指示信息、第二指示信息等的限定。
通过实施本公开实施例，接入网设备可以通过RRC消息，向终端设备发送第一指示信息，以向终端设备指示N个转换连接配置，还可以向终端设备发送第二指示信息，以向终端设备指示激活至少一种转换连接配置。由此，终端设备可以根据网络设备的指示断开与接入网设备的连接，从而既保证了不会对当前连接的接入网设备的通信传输造成影响，又避免了其他接入网业务的失败，提高了多卡终端设备的可靠性。
请参见图4，图4是本公开实施例提供的一种转换连接的控制方法的流程示意图,该方法由接入网设备执行。如图4所示，该方法可以包括但不限于如下步骤：
步骤41，接收终端设备发送的第三指示信息，其中第三指示信息中包含终端设备断开与接入网设备连接的触发事件。
可以理解的是，第三指示信息中包含的触发事件，可以为一个，或者也可以为多个等等，本公开对此不做限定。
需要说明的是，触发事件的具体内容，可以参照本公开其他各实施例的说明，此处不再赘述。
本公开实施例中，为了保证通信传输的正常进行，终端设备可以向接入网设备发送第三指示信息。 从而接入网设备在接收到终端设备发送的第三指示信息之后，即可确定终端设备断开与接入网设备连接的触发事件，从而为通信传输的正常进行提供了保障。
步骤42，响应于接收到终端设备发送的转换连接配置获取请求，向终端设备发送第一指示信息，其中，第一指示信息用于向终端设备指示转换连接配置，终端设备中包括至少两个用户身份识别模块。
比如说，第三指示信息指示的触发事件为寻呼监听和测量，且第一指示信息指示终端设备断开与接入网设备连接的时长为3ms。则终端设备在有寻呼监听需求或者测量需求时，可以断开与当前的接入网设备的连接，并把断开连接的时长控制在3ms内。
或者，第三指示信息指示的触发事件为寻呼监听和测量，且第一指示信息指示寻呼监听对应的断开时长为5ms、测量对应的断开时长为8ms。则终端设备接收到该第一指示信息后，即可在有寻呼监听需求时，断开与当前的接入网设备的连接，并把断开连接的时长控制在5ms内，或者，也可以在有测量需求时，断开与当前的接入网设备的连接，并把断开连接的时长控制在8ms内。
或者，第三指示信息指示的触发事件为寻呼监听和测量，且第一指示信息指示终端设备断开与接入网设备连接的时间图样为：5ms、10ms、12ms。若终端设备接收该第一指示信息的时刻为t时刻，则可以在有寻呼监听需求或者测量需求时，在(t+5)ms的时刻，或者在(t+10)ms的时刻，或者在(t+12)ms的时刻，断开与接入网设备的连接。
或者，第三指示信息指示的触发事件为寻呼监听和读取***消息，第一指示信息指示寻呼监听对应的时间间隔为5ms,读取***消息对应的时间间隔为7ms。即终端设备在进行寻呼监听时，每两次断开与接入网设备连接的时刻间的时间间隔为5ms。或者，终端设备在进行读取***消息时，每两次断开与接入网设备连接的时刻间的时间间隔为7ms。从而终端设备在接收到该第一指示信息后，在有寻呼监听需求时，可以根据该寻呼监听对应的时间间隔，断开与接入网设备的连接。或者在有读取***消息需求时，可以根据该读取***消息对应的时间间隔，断开与接入网设备的连接。
或者，第三指示信息指示的触发事件为寻呼监听和测量，第一指示信息指示的寻呼监听对应的断开时间图样为：5ms、10ms、12ms，测量对应的断开时间图样为3ms、7ms、15ms。若终端设备接收该第一指示信息的时刻为t时刻，则终端设备有寻呼监听需求时，可以在(t+5)ms的时刻，或者在(t+10)ms的时刻，或者在(t+12)ms的时刻，断开与接入网设备的连接。或者，终端设备有测量需求时，可以在(t+3)ms的时刻，或者在(t+7)ms的时刻，或者在(t+15)ms的时刻，断开与接入网设备的连接。
需要说明的是，上述示例只是举例说明，不能作为对本公开实施例中，第三指示信息、第一指示信息等的限定。
需要说明的是，第一指示信息的内容及具体实现方式，可以参照本公开其他各实施例的说明，此处不再赘述。
通过实施本公开实施例，接入网设备可以先接收终端设备发送的第三指示信息，在接收到终端设备发送的转换连接配置获取请求的情况下，向终端设备发送第一指示信息，以向终端设备指示转换连接配置。由此，终端设备可以根据网络设备的指示断开与接入网设备的连接，从而既保证了不会对当前连接的接入网设备的通信传输造成影响，又避免了其他接入网业务的失败，提高了多卡终端设备的可靠性。
请参见图5，图5是本公开实施例提供的一种转换连接的控制方法的流程示意图,该方法由接入网设备执行。如图5所示，该方法可以包括但不限于如下步骤：
步骤51，响应于与终端设备建立连接，向终端设备发送第一指示信息，其中，第一指示信息用于向终端设备指示转换连接配置，终端设备中包括至少两个用户身份识别模块。
其中，接入网设备在与终端设备建立连接的情况下，可以向终端设备发送第一指示信息，以使终端设备可以根据第一指示信息，获知转换连接配置，并基于该转换连接配置进行转换连接。从而既保证了不会对当前连接的接入网设备的通信传输造成影响，又避免了其他接入网业务的失败，提高了多卡终端设备的可靠性。
需要说明的是，第一指示信息的内容及具体实现方式，可以参照本公开其他各实施例的说明，此处不再赘述。
步骤52，确定待激活的转换连接配置。
可以理解的是，待激活的转换连接配置数量可以为一个，或者也可以为多个，本公开对此不做限定。
本公开实施例中，接入网设备可以根据协议约定，或者当前的网络状态，确定待激活的转换连接配置等等，本公开对此不做限定。
步骤53，根据待激活的转换连接配置，确定用于发送第二指示信息的介质访问控制层控制单元中各比特的取值。
其中，介质访问控制层(media access control，MAC)，主要负责控制与连接物理层的物理介质。
可以理解的是，可以协议约定，转换连接配置与用于发送第二指示信息的MAC控制单元(control element，CE)的bit间的对应关系。之后，根据待激活的转换连接配置，确定用于发送第二指示信息的MAC CE中各比特的取值。
比如，协议约定，转换连接配置与用于发送第二指示信息的MAC CE的bit间为一一对应关系。比如：第一个转换连接配置对应于MAC CE的第一个bit，第二个转换连接配置对应于MAC CE的第二个bit，依次类推。本公开对此不做限定。
可选的，可以通过协议约定，将待激活的转换连接配置对应的bit的值取为1，将其余未激活的转换连接配置对应的bit的值取为0。或者，也可以将待激活的转换连接配置对应的bit的值取为特定的数值等等。
比如，待激活的转换连接配置分别为第一个和第三个，则可以将MAC CE的第一个和第三个bit的值取为1。
或者，也可以协议约定，MAC CE的多个bit表征一个转换连接配置。比如，MAC CE中包含4个bit，4个bit的值为0001时，表征第一个转换连接配置；其值为0010时，表征第二个转换连接配置；其值为0011时，对应第三个转换连接配置，其值为0100时，表征第四个转换连接配置等等，依次类推。
需要说明的是，上述示例只是举例说明，不能作为对本公开实施例中MAC CE包含的bit数、各比特的取值以及MAC CE的bit与转换连接配置之间的对应关系等的限定。
可选的，本公开实施例中，MAC CE中包含的bit数可以有两种确定方式，可以协议约定，使用其中任意一种方式。
可选的，可以基于如下公式(1)，确定MAC CE中包含的bit数：
Figure PCTCN2021100745-appb-000005
其中，N为第一指示信息中包括的转换连接配置的数量，
Figure PCTCN2021100745-appb-000006
表示对log 2N向上取整，
Figure PCTCN2021100745-appb-000007
表示对
Figure PCTCN2021100745-appb-000008
取整。
需要说明的是，若采用了公式(1)确定MAC CE中包含的bit数，则仅能通过该MAC CE一次激活一个转换连接配置。
可选的，还可以基于如下公式(2)，确定MAC CE中包含的bit数：
Figure PCTCN2021100745-appb-000009
其中，N为第一指示信息中包括的转换连接配置的数量，
Figure PCTCN2021100745-appb-000010
表示对
Figure PCTCN2021100745-appb-000011
取整。
需要说明的是，若采用了公式(2)确定MAC CE中包含的bit数，则可以通过该MAC CE一次激活一个转换连接配置，也可以一次激活多个转换连接配置。
比如，N取值为9，使用公式(1)确定MAC CE中包含的bit数，则MAC CE的结构可以如图5A所示，其中，R为占位符，c1至c7分别为MAC CE中包含的各个bit。
或者，使用公式(2)确定MAC CE中包含的bit数，则MAC CE的结构可以如图5B所示，其中，R为占位符，c1至c15分别为MAC CE中包含的各个bit。
需要说明的是，上述示例只是举例说明，不能作为对本公开实施例中N的取值、MAC CE中包含的bit数等的限定。
步骤54，通过MACCE向终端设备发送第二指示信息，其中，第二指示信息用于激活至少一种转换连接配置。
本公开实施例中，接入网设备在确定用于发送第二指示信息的MAC CE中各比特的取值之后，即可通过MACCE向终端设备发送第二指示信息，以向终端设备指示激活至少一种转换连接配置。从而终端设备在接收到该MAC CE后，即可以在有业务需求时，激活至少一种转换连接配置。
通过实施本公开实施例，接入网设备可以在与终端设备建立连接的情况下，向终端设备发送第一指示信息，以向终端设备指示转换连接配置，接入网设备还可以确定待激活的转换连接配置，之后根据待激活的转换连接配置，确定用于发送第二指示信息的介质访问控制层控制单元中各比特的取值，再通过MACCE向终端设备发送第二指示信息。由此，终端设备可以根据网络设备的指示断开与接入网设备的连接，从而既保证了不会对当前连接的接入网设备的通信传输造成影响，又避免了其他接入网业务的失败，提高了多卡终端设备的可靠性。
