下面结合图2对本申请提出的方案进行详细说明。应理解,图2所示的方案可以适用于图1所示的系统。此时,第一网元为意图转译网元。
S201,意图管理网元向意图转译网元发送第一请求消息,该第一请求消息用于请求实施第一意图。相应地,意图转译网元接收该第一请求消息。
S202,意图转译网元进行第一判定,该第一判定为判定第一意图与系统中正在运行的意图之间是否存在语法冲突。
当第一判定的结果为是,且不实施第一意图时,该方法还包括:
S203,意图转译网元根据第一判定的结果从本地获取第一信息,第一信息指示N个意图,该第一信息包括N个意图的标识信息,该N个意图为与第一意图存在冲突的全部意图,N为正整数。此外,意图转译网元生成并保存第四信息,该第四信息指示第一信息与第一意图对应。该第四信息包括第一信息的标识信息和第一意图的标识信息。

在一种可能的实现方式中,意图转译网元还可以根据第一判定的结果从本地获取第五信息,该第五信息中包括N个意图中的每个意图与第一意图产生冲突的字段。
例如,系统中正在运行的意图为意图#1、意图#2、意图#3、意图#4,该第一意图为意图#5,并且经过第一判定后,意图转译网元确定意图#1、意图#2、意图#3与意图#5冲突。那么,第一信息和第五信息可以如表1所示。其中,字段#i为意图#i与意图#5产生冲突的字段,i从1遍历到3。
表1
第一信息 第五信息
意图#1 字段#1
意图#2 字段#2
意图#3 字段#3
S204,意图转译网元向意图管理网元发送第二请求消息,该第二请求消息用于请求更新意图的上下文。相应地,意图管理网元接收该第二请求消息。
第二请求消息指示将第一意图设置为冲突态。
除此之外,第二请求消息中还可以包括其他信息,下面分情况进行说明:
情况1:
该第二请求消息中还包括第一信息。
情况2:
该第二请求消息中还包括第一信息和第一信息的标识信息。
S205,意图管理网元根据第二请求消息更新意图的上下文。
具体地,意图管理网元根据第二请求消息将第一意图设置为冲突态。
此外,意图管理网元还可以根据第二请求消息执行其他的操作,下面分情况说明:

与S204中的情况1对应,意图管理网元将第一信息保存。
在一种可能的实现方式中,意图管理网元还可以保存冲突类型信息。例如,在第一信息中添加冲突类型信息,并保存。
情况2:
与S204中的情况2对应,意图管理网元根据第一信息,在N个意图的上下文中添加第一信息的标识信息和冲突类型信息。
例如,N个意图的标识为意图#1、意图#2和意图#3。意图管理网元可以在意图#1的上下文中添加第一信息的标识信息和冲突类型信息,如表2所示。类似地,意图管理网元可以更新意图#2和意图#3的上下文。
表2
意图#1的上下文
……
第一信息的标识信息
冲突类型信息
应理解,意图管理网元可以根据第二请求消息的发送方,确定冲突类型信息。例如,当意图管理网元从意图转译网元接收到第二请求消息时,意图管理网元确定该冲突类型信息指示语法冲突。
S206,意图管理网元确定N个意图中的一个或多个意图的状态发生变化。
下文以第一意图为意图#5,N个意图包括意图#1、意图#2和意图#3,意图管理网元确定意图#1的状态发生变化为例进行说明。即,该N个意图为与意图#5冲突的全部意图。
下面介绍意图管理网元确定意图#1的状态发生变化的方式。
方式1:
意图消费网元指示意图管理网元将意图#1删除,或者将意图#1设置为冲突态,或者修改意图#1。
意图管理网元根据意图消费网元的上述指示确定意图#1的状态发生变化。
方式2:
意图管理网元发送第三请求消息,该第三请求消息请求实施意图#6。
意图转译网元进行语法冲突检测,确定意图#1与意图#6存在语法冲突。或者,意图执行网元进行操作冲突检测,确定意图#1与意图#6存在操作冲突。
意图转译网元或意图执行网元指示将意图#1设置为冲突态。
应理解,当意图#1与意图#6存在冲突时,意图转译网元或意图执行网元选择实施意图#6。在一种可能的实现方式中,意图转译网元或意图执行网元可以基于意图的优先级进行选择。例如,意图#6的优先级高于意图#1。
意图管理网元根据意图转译网元或意图执行网元的上述指示确定意图#1的状态发生变化。

S207,意图管理网元向意图转译网元发送第二信息,该第二信息指示N个意图中的一个或多个意图的状态发生变化。相应地,意图转译网元接收该第二信息。
应理解,该第二信息包括该一个或多个意图的标识信息。
下面介绍意图管理网元向意图转译网元发送第二信息的两种情况:
情况1:
与S205中的情况1对应,由于意图管理网元保存了第一信息,当意图管理网元确定某个意图的状态发生变化时,意图管理网元进一步确定该意图是否为第一信息中包含的意图。当该意图为第一信息中包含的意图时,意图管理网元向意图转译网元发送第二信息。
例如,当S206中意图管理网元确定意图#1的状态变化时,意图管理网元进一步确定意图#1是第一信息中包含的意图。此时,意图管理网元向意图转译网元发送第二信息,第二信息中包括意图#1的标识。
应理解,意图管理网元可以根据冲突类型信息,确定向意图转译网元发送第二信息。
情况2:
与S205中的情况2对应,当意图管理网元确定某个意图的状态发生变化时,意图管理网元查询该意图的上下文。当该意图的上下文中包括冲突类型信息和第一信息的标识信息时,意图管理网元向意图转译网元发送第二信息,该第二信息包括该意图的标识信息和第一信息的标识信息。
例如,S206中,意图管理网元确定意图#1的状态发生变化。意图管理网元查询意图#1的上下文,并且从意图#1的上下文中获取第一信息的标识信息和冲突类型信息。意图管理网元根据冲突类型信息,确定向意图转译网元发送第二信息,并且在第二信息中包含意图#1的标识信息和第一信息的标识信息。应理解,意图管理网元也可以根据该冲突类型信息,确定意图#1的状态发生变化后需要立即向意图转译网元发送第二信息。
S208,意图转译网元根据第二信息更新第一信息。
与S207的情况1对应,第二信息中不包括第一信息的标识信息,此时意图转译网元可以对某一信息进行查询,确定该信息中是否包括第二信息所指示的一个或多个意图的标识。当该信息中包括第二信息所指示的一个或多个意图的标识时,对该信息进行更新。
例如,意图转译网元中保存了第一信息,第一信息包括意图#1、意图#2、意图#3的标识,该第一信息为与意图#5冲突的意图。意图转译网元中还保存了第六信息,第六信息包括意图#4的标识,该第六信息为与意图#6冲突的意图。意图转译网元收到第二信息,第二信息指示意图#1的状态发生变化,并且第二信息中包括意图#1的标识。此时,意图转译网元查询第一信息和第六信息,当确定第一信息中包括意图#1的标识时,对第一信息进行更新;当确定第六信息中不包括意图#1的标识时,不对第六信息进行更新。
与S207的情况2对应,第二信息中包括第一信息的标识信息。此时,意图转译网元可以根据第一信息的标识信息,对第一信息进行更新。
根据本申请的方案,意图转译网元获取的第二信息中可以包括第一信息的标识信息,使得意图转译网元获知需要对第一信息进行更新,而不是对其他信息进行更新,从而提高了意图转译网元根据第二信息更新第一信息的效率。
下面介绍意图转译网元根据第二信息更新第一信息的方式:
方式1:
意图转译网元根据第二信息在第一信息中对一个或多个意图进行标记。在一种可能的实现方式中,可以在第一信息中添加特定的字段,来对一个或多个意图进行标记。
例如,第二信息中包括意图#1的标识信息。意图转译网元根据意图#1的标识信息在第一信息中对意图#1进行标记。在第一信息中包括意图#1、意图#2、意图#3的情况下,更新后的第一信息如表3所示。
表3
意图#1
意图#2  
意图#3  
方式2:
意图转译网元根据第二信息在第一信息中将一个或多个意图的标识删除。
例如,第二信息中包括意图#1的标识信息。意图转译网元根据意图#1的标识信息在第一信息中将意图#1的标识删除。在第一信息中包括意图#1、意图#2、意图#3的情况下,更新后的第一信息如表4所示。
表4
 
意图#2
意图#3
应理解,本申请中S206-S208的过程可以执行一次或多次。

具体地,意图转译网元可以重新对第一意图进行语法冲突检测。
根据本申请的方案,意图转译网元通过生成第四信息,明确第一信息是与第一意图相关联的。因此,意图转译网元在确定上述N个意图的状态均发生变化后,需要发起启用第一意图的流程,而不是发起启用其他意图的流程。
根据本申请的方案,在第一意图处于冲突态的情况下,意图转译网元可以在确定与第一意图存在冲突的全部意图的状态均发生变化后,发起启用第一意图的流程。相比于,通过意图管理网元周期性地发起启用第一意图的流程,采用本申请的方案可以及时、准确、高效地重新发起启用第一意图的流程。
