Description

通信场景切换方法、装置、终端设备和网络设备 技术领域
本申请涉及通信领域，特别是涉及了一种通信场景切换方法、装置、终端设备和网络设备
背景技术
在移动数据通讯的过程中，常常会出现功率变化或资源块跳变(RB hopping)的情况。例如，将通信信号从新一代移动通信系统(New Radio，简称NR)信号切换为长期演进系统(Long Term Evolution，简称LTE)的信号。此时，需要对用于通信信号切换的切换时间进行限制，以避免由于功率变化或资源块跳变导致解调误码率提高的问题。基于该情况，在3GPP协议中引入了时间模板(Time mask)，该时间模板规定了由原通信场景下的信号切换至新的通信场景下的一些时间限制，包括：原通信场景下信号功率由ON到OFF的过渡时间(Tp1)限制、由原通信场景下的子帧或时隙切换至新的通信场景下的子帧或时隙的切换时间限制、以及在新的通信场景下信号功率由OFF到ON的过渡时间(Tp2)限制。通常，用户终端需要按照上述时间模板的要求进行信号的切换以及传输。
目前随着5G技术的深入发展，由5G通信场景切换至其他制式的通信场景，或者由其他制式的通信场景切换为5G制式的通信场景越来越普遍，基于传统技术中时间模板的规定进行信号的切换已经无法满足目前的场景切换需求，其灵活性不够的弊端也越来越明显。

时间模板(Time mask)：包含第一过渡时长、时间资源切换所需的切换时长、第二过渡时长。其中，下述实施例涉及到的信号切换操作中的关闭信号功率的操作所需的时长为第一过渡时长，时间资源切换的操作所需的时长为切换时长，开启信号功率的操作所需的时长为第二过渡时长。
侧行链路(sidelink，简称SL)：设备到设备(Device-to-Device，简称D2D)之间通信的链路。
空口Uu：接入网设备和终端设备之间的无线传输的虚拟接口。
通信场景切换：在将第一通信场景切换为第二通信场景，需要先将第一通信场景的信号功率关闭，再将第一通信场景的第一时域资源切换为第二通信场景的第二时域资源的时域资源，然后再将第二通信场景的信号功率开启，以完成将第一通信场景切换为第二通信场景的过程。
目前，传统技术在具体确定用于执行通信场景切换操作的相应资源位置时，特别是将5G通信场景切换至其他制式的通信场景，或者由其他制式的通信场景切换为5G制式的通信场景，由于5G制式的通信场景为新的通信场景，相关协议对5G制式的时域资源的限定较少，因此，在进行其他制式的通信场景与5G制式的通信场景之间的相互切换时，通常是将时间模板对应的资源位置设置在5G制式的时域资源上。随着5G技术的深入发展，由5G通信场景切换至其他制式的通信场景，或者由其他制式的通信场景切换为5G制式的通信场景越来越普遍，基于传统技术中所确定的时间模板对应的资源位置的灵活性不够。
基于上述传统技术，本申请实施例提供了一种通信场景切换方法，其所确定的用于终端设备执行通信场景切换操作的目标资源位置，可以根据终端设备在进行通信场景切换时功率开关过渡所需的过渡时长，以及当前通信场景下第一时域资源的最后一个符号的符号长度，灵活的设置在第一时域资源上，或 者设置在第一时域资源和第二时域资源上，提高了所确定的目标资源位置的灵活性。
下面以具体地实施例对本申请的技术方案以及本申请的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。下面将结合附图，对本申请的实施例进行描述。
图2为一个实施例提供的一种通信场景切换方法的流程图。该方法的执行主体可以为图1所示场景中的第一终端设备100或者接入网设备300，本实施例涉及的是如何确定用于执行通信场景切换操作的目标资源位置的具体实现过程。如图2所示，该方法包括以下步骤：
S201、获取终端设备的功率开关通信场景切换时的过渡时长。
具体的，本实施例中的“功率开关”可以包括功率由开到关的过程，也可以包括功率由关到开的过程。在关闭或打开功率开关时，通常需要一段时间以使功率能达到预设的功率值，因此，通常会先确定出信号功率开启或关闭所需的最长的时长作为过渡时长，以使信号功率能够在过渡时长内完成开启或关闭。需要说明的是，闭或打开功率开关可以是指具体的关闭或打开开关或器件，例如，上述器件可以是指功率放大器，打开功率开关可以是指打开功率放大器和相关的开关。其中，在开启新的通信场景的功率时，通常需要Tμs，才能将功率从0到XdBm，其中，X为预设的功率值，T为过渡时长。需要说明的是，过渡时长是预设的开启或关闭功率所需的最长时长，终端设备在实际的开启或关闭功率时，所需的时长通常不长于过渡时长。
可选的，本实施例中的过渡时长可以是终端设备在第一通信场景下功率由开到关所需的时长，还可以是终端设备切换至第二通信场景下功率由关到开所需的时长。
S202、获取第一通信场景下第一时域资源的最后一个符号的符号长度。
其中，时域资源可以包括多个连续的符号，每个符号代表一段时长内的频域资源。不同的通信场景对应的时域资源可以相同，也可以不同，本申请实施例对此不做限制。
S203根据过渡时长和符号长度，确定在目标资源位置上终端设备能够执行的信号切换操作。
其中，切换操作用于将终端设备从第一通信场景切换至第二通信场景，目标资源位置包括第一时域资源，或者，包括第一时域资源和第二通信场景下的第二时域资源。
其中，信号切换操作可以是指将终端设备从第一通信场景切换至第二通信场景所需的操作，该信号切换操作可以是一个操作，还可以是多个操作。可选的，该信号切换操作可以是关闭功率开关的操作，还可以开启功率开关的操作，还可以是从第一通信场景下的第一时域资源切换至第二通信场景下的第二时域资源的切换操作，本实施例对信号切换操作的具体内容并不做限定，只要其包括能够将终端设备从第一通信场景切换至第二通信场景所需的操作即可。
当终端设备获取到过渡时长和最后一个符号的符号长度之后，可以确定终端设备在目标资源位置上执行的信号切换操作。可选的，终端设备可以根据过渡时长和最后一个符号的符号长度的大小来确定在目标资源位置上执行的信号切换操作，还可以是根据过渡时长和最后一个符号的符号长度之间的比值来确定目标资源位置上执行的信号切换操作，甚至还可以是根据过渡时长和最后一个符号的符号长度之间的差值与预设的差值阈值之间的大小关系来确定在目标资源位置上执行的信号切换操作，本实施例对终端设备如何确定在目标资源位置上终端设备能够执行的信号切换操作的具体方式并不做限定，只要其利用到了过渡时长和符号长度即可。
可选的，上述“在目标资源位置上终端设备能够执行的信号切换操作”可以是：在第一时域资源上进行信号切换操作中全部操作；也可以在第一时域资源上进行信号切换操作中的部分操作，在第二通信场景下的第二时域资源上进行另一部分操作；还可以将信号切换操作中的一个操作的部分操作分配在第一时域资源上执行，将信号切换操作中的一个操作的另一部分操作分配在第二时域资源上执行，本申请实施例对此不做限定。
需要说明的是，本实施例中，终端设备确定的信号切换操作不仅可以发生在第一通信场景下的第一时域资源上，还可以是同时占用第一通信场景下的第一时域资源和第二通信场景下的第二时域资源，具体如何占用，依赖的是上述所获取的过渡时长和最后一个符号的符号长度。当确定出目标资源位置上终端设备能够执行的信号切换操作之后，实际上也就相当于确定出终端设备在进行通信场景切换时的时间 模板。基于上述描述可知，时间模板对应的资源位置可以包括第一时域资源，也可以包括第一时域资源和第二时域资源，其灵活性较高。
上述信号切换方法，通过获取终端设备的功率开关通信场景切换时的过渡时长，以及第一通信场景下第一时域资源的最后一个符号的符号长度，进而根据过渡时长和符号长度，确定在目标资源位置上终端设备能够执行的从第一通信场景切换至第二通信场景所需的至少一个操作的信号切换操作，其中，目标资源位置包括第一时域资源，或者，包括第一时域资源和终端设备切换至第二通信场景下的第二时域资源，也即是说，所确定的用于终端设备执行通信场景切换操作的目标资源位置，可以根据终端设备在进行通信场景切换时功率开关过渡所需的过渡时长，以及第一通信场景下第一时域资源的最后一个符号的符号长度，灵活的设置在第一时域资源上，或者设置在第一时域资源和第二时域资源上，提高了目标资源所在位置的灵活性。
可选的，上述信号切换操作包括以下操作中的至少一个：关闭功率开关、开启功率开关、以及切换时域资源。
在具体的根据过渡时长和符号长度确定在目标资源位置上终端设备能够执行的信号切换操作时，可以根据终端设备在第一通信场景切换时的第一过渡时长和符号长度来确定，也可以根据终端设备在第二通信场景切换时的第二过渡时长和符号长度来确定，本申请实施例对此不做限定。下面通过以下实施例来描述根据第一过渡时长和符号长度来确定目标资源位置的具体过程。
在其中一个实施例中，当终端设备获取到第一过渡时长时，上述S203可以为：若符号长度大于或者等于第一过渡时长，则确定在第一时域资源上终端设备执行的第一信号切换操作包括：关闭功率开关以及切换时域资源，确定在第二时域资源上终端设备执行的第二信号切换操作包括切换时域资源和开启功率开关。

另外，在符号长度大于或等于第一过渡时长时，终端设备还确定了在第二时域资源上执行的第二信号切换操作包括切换时域资源和开启功率开关。如上述所说，第二时域资源上发生的切换时域资源为上述切换时域资源的另一部分过程。在切换时域资源操作结束后，终端设备开启功率开关。

另外，在符号长度大于或等于第一过渡时长时，终端设备还确定了在第二时域资源上执行的第二信号切换操作包括切换时域资源和开启功率开关。如上述描述所述的内容可知，第二时域资源上发生的切换时域资源为上述切换时域资源的全部过程。在切换时域资源操作结束后，终端设备开启功率开关。可选的，终端设备可以在第二时域资源开始之后，间隔预设的时刻，再开始进行切换时域资源，也可以在第二时域资源开始之后，间隔预设数量个符号，再开始进行切换时域资源，本申请实施例对此不做限制。可选的，第二信号切换操包括终端设备在第二时域资源开始时刻进行切换时域资源，并在时域资源切换后开启功率开关。
由该实施例描述可知，信号切换操作不仅可以占用第一通信场景下的第一时域资源，还可以占用第二通信场景下的第二时域资源，也即是说，信号切换操作所占用的资源位置，可以灵活的设置在第一时域资源上，或者设置在第一时域资源和第二时域资源上，提高了目标资源所在位置的灵活性。
在另一个实施例中，当终端设备获取到第一过渡时长时，上述S203还可以为：若符号长度小于第一过渡时长，则确定在第一时域资源上终端设备执行的第一信号切换操作包括：关闭功率开关，在第二时域资源上终端设备执行的第二信号切换操作包括：切换时域资源和开启功率开关。
在获取了终端设备在通信场景切换时的第一过渡时长时，可以将第一时域资源的最后一个符号的符号长度对第一过渡时长相比较，若符号长度小于第一过渡时长时，则在第一时域资源上执行的第一信号切换操作可以只包括：关闭功率开关。在第二时域资源上终端设备执行的第二信号切换操作包括切换时域资源和开启功率开关。需要说明的是，本实施例，通信场景切换的第一过渡时长所占用的资源，一部分在在第一时域资源的最后一个符号上，另一部分过程在第二时域资源上。
可选的，上述第一信号切换操作可以用于指示终端设备在关闭功率开关之后间隔第一过渡时长，即刻在第二时域资源上执行切换时域资源。可选的，上述第一信号切换操作包括终端设备在第一时域资源的最后一个符号关闭功率开关，第二信号切换操作包括在预设时刻切换时域资源，在切换时域资源之后开启功率开关；预设时刻为关闭功率开关的时刻之后间隔第一过渡时长的时刻。也即是说，上述第一信号切换操作指示了执行关闭功率开关这个操作的时序以及执行该操作所占用的具体的符号位置。
由该实施例描述可知，信号切换操作不仅可以占用第一通信场景下的第一时域资源，还可以占用第二通信场景下的第二时域资源，也即是说，信号切换操作所占用的资源位置，可以灵活的设置在第一时域资源上，或者设置在第一时域资源和第二时域资源上，提高了目标资源所在位置的灵活性。
上述实施例描述了如何根据第一过渡时长和符号长度确定目标资源位置的具体过程，下面通过以下实施例来描述如何根据第二过渡时长和符号长度确定目标资源位置的具体情况。
在一个实施例中，终端设备在获取在进行通信场景切换时功率开关过渡所需的过渡时长可以是获取终端设备在第二通信场景切换时开启功率开关所需的第二过渡时长。上述S203“根据过渡时长和符号长度，确定在相应资源位置上终端设备能够执行的信号切换操作”可以包括：若符号长度大于或者等于第二过渡时长，则确定在第一时域资源上终端设备执行的第一信号切换操作包括：关闭功率开关、切换时域资源以及开启功率开关。。

由该实施例描述可知，信号切换操作可以占用第一通信场景下的第一时域资源，在一种可能的情况下，第一通信场景为LTE时，可以在LTE对应的时域资源上确定相应资源位置，提高了所确定的相应资源位置的灵活性。
在一个实施例中。上述S203“根据过渡时长和符号长度，确定在相应资源位置上终端设备能够执行的信号切换操作”可以包括：若符号长度小于第二过渡时长，则确定在第一时域资源上终端设备执行的第一信号切换操作包括：关闭功率开关、切换时域资源以及开启功率开关。

由该实施例描述可知，信号切换操作可以占用第一通信场景下的第一时域资源，在一种可能的情况下，第一通信场景为LTE时，可以在LTE对应的时域资源上确定目标资源位置，提高了目标资源所在位置的灵活性。
在一个实施例中。上述S203“根据过渡时长和符号长度，确定在相应资源位置上终端设备能够执行的信号切换操作”可以包括：若符号长度小于第二过渡时长，则确定在第一时域资源上终端设备执行的第一信号切换操作包括：关闭功率开关以及切换时域资源、开启功率开关。

在一种可能的实施例中，在确定相应资源位置时，还可以根据最后一个符号的配置信息、过渡时长和符号长度，确定在相应资源位置上终端设备能够执行的信号切换操作。可选的，如图3所示，该方法还包括：
S301、获取最后一个符号的配置信息，配置信息用于指示最后一个符号用于调整保护间隔、最后一个符号用于信号传输或最后一个符号为空白符号不被调度。
其中，配置信息可以用于指示最后一个符号的传输特性，可以是该符号专门被用于调整保护间隔，也可以指示该符号能够被用于信号传输，还可以指示该符号为不被调度的空白符号，本申请实施例对此 不做限制。若当前场景为LTE SL时，最后一个符号的配置信息通常被固定设置为用于指示最后一个符号专门用于调整保护间隔。若当前场景为NR sidelink，最后一个符号的配置信息也被固定设置为指示最后一个符号专门用于调整保护间隔。
S302、根据最后一个符号的配置信息、过渡时长和符号长度，确定在目标资源位置上终端设备能够执行的信号切换操作。
在获取了最后一个符号的配置信息之后，可以根据最后一个符号的配置信息、过渡时长和符号长度，确定在目标资源位置上终端设备能够执行的信号切换操作。特别是在最后一个符号的配置信息指示该符号被专门用于调整保护间隔时，则可以充分的利用该符号，在该符号上终端设备能够执行信号切换操作。
例如，当最后一个符号的配置信息指示该符号专门用于调整保护间隔时，则在符号长度大于或者等于第一过渡时长，确定在第一时域资源上终端设备执行的第一信号切换操作包括：关闭功率开关以及切换时域资源，确定在第二时域资源上终端设备执行的第二信号切换操作包括开启功率开关。其中，第一信号切换操作包括终端设备在第一时域资源的最后一个符号上关闭功率开关之后间隔第一过渡时长即刻进行切换时域资源。
当最后一个符号的配置信息指示该符号专门用于调整保护间隔时，则在符号长度大于或者等于第一过渡时长，则确定在第一时域资源上终端设备执行的第一信号切换操作包括：关闭功率开关，确定在第二时域资源上终端设备执行的第二信号切换操作包括切换时域资源和开启功率开关。其中，第一信号切换操作包括终端设备在第一时域资源的最后一个符号上关闭功率开关。第二信号切换操作用于指示终端设备在第二时域资源开始时刻进行切换时域资源，并在时域资源切换后开启功率开关。
当最后一个符号的配置信息指示该符号专门用于调整保护间隔时，则在符号长度小于第一过渡时长，则确定在第一时域资源上终端设备执行的第一信号切换操作包括：关闭功率开关，确定在第二时域资源上终端设备执行的第二信号切换操作包括：切换时域资源和开启功率开关。其中，第一信号切换操作包括终端设备在第一时域资源的最后一个符号关闭功率开关，第二信号切换操作包括在预设时刻切换时域资源，在切换时域资源之后开启功率开关；预设时刻为关闭功率开关的时刻之后间隔第一过渡时长的时刻。
当最后一个符号的配置信息指示该符号专门用于调整保护间隔时，则在符号长度大于或者等于第二过渡时长，则确定在第一时域资源上终端设备执行的第一信号切换操作包括：关闭功率开关以及切换时域资源、开启功率开关。其中，第一信号切换操作包括终端设备在最后一个符号之前的其他符号上执行关闭功率开关以及切换时域资源，并在最后一个符号上开启功率开关。
当最后一个符号的配置信息指示该符号专门用于调整保护间隔时，则在符号长度小于第二过渡时长，则确定在第一时域资源上终端设备执行的第一信号切换操作包括：关闭功率开关、切换时域资源以及开启功率开关。其中，第一信号切换操作包括终端设备在第一时域资源上关闭功率开关以及进行切换时域资源，并在最后一个符号之前的相邻符号上开启功率开关。
当最后一个符号的配置信息指示该符号专门用于调整保护间隔时，则在符号长度小于第二过渡时长，则确定在第一时域资源上终端设备执行的第一信号切换操作包括：关闭功率开关以及切换时域资源、开启功率开关。其中，第一信号切换操作用于指示终端设备在第一时域资源上关闭功率开关以及进行切换时域资源，并在最后一个符号开启功率开关。
上述信号切换方法，终端设备通过获取最后一个符号的用于指示最后一个符号被用于调整保护间隔、最后一个符号能够被用于信号传输或最后一个符号为空白符号不被调度的配置信息之后，在根据过渡时长和符号长度的基础上，引入最后一个符号的配置信息，作为确定在目标资源位置上终端设备能够执行的信号切换操作的一个因素，进一步地提高了所确定的目标资源位置上终端设备能够执行的信号切换操作的灵活性。
在一个实施例中，终端设备可以直接根据预设的最后一个符号的配置信息、过渡时长和符号长度，确定在相应资源位置上终端设备能够执行的信号切换操作，其中，配置信息用于指示最后一个符号用于调整保护间隔、最后一个符号用于信号传输或最后一个符号为空白符号不被调度。
本实施例中，最后一个符号的配置信息是预设的配置信息，该配置信息用于指示最后一个符号被用于调整保护间隔、最后一个符号能够被用于信号传输或最后一个符号为空白符号不被调度。终端设备在具体的根据预设的最后一个符号的配置信息、过渡时长和符号长度，确定在相应资源位置上终端设备能够执行的信号切换操作，可以与上述实施例中所描述的类似，此处不再赘述。
在上述实施例的基础上，还可以通过确定执行信号切换操作的占用符号的占用长度，和该符号的符号长度，确定该符号是否还可以用于数据传输，下面通过图4-6所示实施例来说明。
如图4所示，该方法还包括以下步骤：
S401、确定信号切换操作在目标符号上所占用的占用长度；目标符号包括最后一个符号、第一时域资源中与最后一个符号邻接的符号或第二时域资源中的第一个符号。
有上述实施例的描述可知，在进行信号切换操作时，第一时域资源上的最后一个符号或第一时域资源中与最后一个符号邻接的符号，可以作为信号切换操作的起始符号，第一时域资源上的最后一个符号或者第二时域资源中的第一个符号，可以作为信号切换操作的终止符号，这些目标符号存在只被部分占用的情况。本申请实施例正是基于这些目标符号存在只被部分占用的情况，来说明这些目标符号是否能够被用于数据传输。在通过获取上述目标符号上被信号切换操作所占用的占用长度时，可以根据目标符号上功率变化值来确定占用长度，例如，可以将功率变化值超过预设阈值的符号内的长度确定为占用长度。
S402、基于占用长度与目标符号的符号长度，确定目标符号是否可用于信号传输。
在具体的基于占用长度与目标符号的符号长度，确定目标符号是否可用于信号传输时，可以通过占用长度与目标符号的符号长度之间的差值确定目标符号是否可用于信号传输，也可以通过占用长度与目标符号的符号长度之间的比值来确定，本申请实施例对此不做限定，只要能基于占用长度与目标符号的符号长度，确定目标符号是否可用于信号传输即可。可选的，基于占用长度与目标符号的符号长度之间的重叠关系，确定目标符号是否可用于信号传输。
其中，重叠关系可以指示占用长度占目标符号的符号长度的比例，也可以指示目标符号除占用长度之外的剩余符号长度，还可以指示占用长度的绝对值，本申请实施例对此不做限定。例如，当重叠关系小于预设重叠阈值时，可以将目标符号用于信号传输。可选的，还可以基于重叠关系和目标符号的调制解调方法，确定目标符号是否可以用于信号传输。由于不同的调制解调方法对性能的要求不同，因此可以基于不同的调制解调方法，对性能要求高的调制解调方法对应的目标符号均不用做信号传输。例如，256QAM中的EVM性能要求很高，当目标符号对应的调制解调方法为256QAM，则无论目标符号的重叠关系是否小于预设重叠阈值时，该目标符号均不被用作信号传输。
在一个实施例中，如图5所示，上述S402“基于占用长度与目标符号的符号长度之间的重叠关系，确定目标符号是否可用于信号传输”一种可能的实现方法包括：
S501、获取占用长度占目标符号的符号长度的比例。
S502、若比例大于或者等于第一门限值，则确定目标符号不可用于信号传输。
其中，第一门限值可以是预设的第一门限值，也可以是协议规定的第一门限值，本申请实施例对此不做限制。
在一个实施例中，如图6所示，上述S402“基于占用长度与目标符号的符号长度之间的重叠关系，确定目标符号是否可用于信号传输”一种可能的实现方法包括：
S601、获取目标符号除占用长度之外的剩余符号长度。
S602、若剩余符号长度小于第二门限值，则确定目标符号不可用于信号传输。
其中，第二门限值可以是预设的第二门限值，也可以是协议规定的第二门限值，本申请实施例对此不做限制。
可选的，若占用长度不为0，则确定目标符号不可用于信号传输。
上述信号切换方法，确定信号切换操作在最后一个符号、第一时域资源中与最后一个符号邻接的符号或第二时域资源中的第一个符号所占用的占用长度，并基于占用长度与目标符号的符号长度，确定目 标符号是否可用于信号传输。使得目标符号不仅可以用于信号切换操作，还可以用于信号传输，大大提高了目标符号的使用效率，也提高了目标符号的灵活性。
在一个实施例中，可以根据当前通信场景下终端设备支持的过渡时间能力，确定过渡时长。
在一个实施例中，可以根据第一通信场景下的子载波间隔，确定最后一个符号的符号长度。
由于LTE中子载波间隔均为15KHz,则可以根据LTE中子载波间隔均为15KHz，确定LTE中的时域资源的符号的符号长度为66.67μS,也即是确定最后一个符号的符号长度为66.67μS；在NR的时域资源上，子载波间隔可以是15KHz、30KHz、60KHz或120KHz，则可以根据上述子载波间隔，确定其对应的NR的时域资源上的符号的符号长度分别为66.67μS、33μS、17μS或8.5μS。
可选的，上述切换通信场景包括：
新无线NR系统侧行链路SL通信场景切换为长期演进LTE系统SL通信场景；
新无线NR系统SL的通信场景切换新无线NR系统空口Uu的通信场景；
新无线NR系统SL的通信场景切换为长期演进LTE系统空口Uu的通信场景；
长期演进LTE系统SL的通信场景切换为新无线NR系统SL的通信场景；

长期演进LTE系统空口Uu通信场景切换为新无线NR系统SL的通信场景；
同一制式的通信系统中第一信号切换为第二信号；
同一制式的通信系统中第一信道切换为第二信道。
其中，具体的切换过程可以如上述描述可知，在此不再赘述。
应该理解的是，虽然图2-6的流程图中的各个步骤按照箭头的指示依次显示，但是这些步骤并不是必然按照箭头指示的顺序依次执行。除非本文中有明确的说明，这些步骤的执行并没有严格的顺序限制，这些步骤可以以其它的顺序执行。而且，图2-6中的至少一部分步骤可以包括多个子步骤或者多个阶段，这些子步骤或者阶段并不必然是在同一时刻执行完成，而是可以在不同的时刻执行，这些子步骤或者阶段的执行顺序也不必然是依次进行，而是可以与其它步骤或者其它步骤的子步骤或者阶段的至少一部分轮流或者交替地执行。
