    • A service creation system for a communications network of the intelligent network type has 3 different levels at which service creation activities can be carried out, these being SCE1, SCE2 and SCE3. The use of separate levels allows access to the service creation system to be kept functionally separate for users having different interests in the network. Hence, features which have to be installed at the network element level for a selected service to be available can be created in SCE1. Marketable service features, which give a view of features in that they encapsulate call handling logic thereof together with support and management descriptions of the feature, can be created in SCE2. Service packages, which permit collection of marketable service features to meet requirements of a service together with service-specific support and management information, can be created in either of SCE2 or SCE3. The service provider at SCE2 creates and tests edit graphs which comprise ordered sequences of marketable service features. These are then made available to the customer at SCE3. Profiles, which list the features relevant to a service for a user and provide data slots for the data necessary to each feature, can be provisioned and modified in SCE3 by the creation of execute graphs from edit graphs. In addition to marketable service features, metafeatures can be embedded in edit graphs. These are similar to marketable service features but have no associated screen information. This allows the user to generate execute graphs from what appears to be a blank screen but in practice has embedded constraints by means of the metafeatures, thus ensuring that the execute graph is still within tested constraints.
    • 智能网类型通信网络的业务创建系统具有3个不同层次,可进行业务创建活动,分别为SCE1,SCE2和SCE3。 使用单独的级别允许访问服务创建系统以在网络中具有不同兴趣的用户保持功能性分离。 因此,可以在SCE1中创建必须在网元级别安装所选服务可用的功能。 可以在SCE2中创建可销售的服务功能,其特征在于它们封装了其呼叫处理逻辑以及特征的支持和管理描述。 可以在SCE2或SCE3中创建能够收集可销售的服务功能以满足服务要求以及服务特定支持和管理信息的服务包。 SCE2的服务提供商创建和测试编辑图形,其中包含可销售的服务功能的有序序列。 然后,这些可在SCE3上提供给客户。 配置文件列出与用户的服务相关的功能,并为每个功能所需的数据提供数据时隙,可以通过从编辑图形创建执行图形在SCE3中进行配置和修改。 除了可销售的服务功能外,还可以在编辑图形中嵌入元数据。 这些类似于可销售的服务功能,但没有相关的屏幕信息。 这允许用户从看起来是空白屏幕生成执行图形,但实际上已经通过元件进行嵌入式约束,从而确保执行图仍在测试约束之内。
