摘要
给出了内嵌业务逻辑子系统(ESL)的定义,描述了一个以"业务与呼叫控制分离"为典型特征之一的软交换设备的系统构成。给出了内嵌业务逻辑子系统设计的依据和相关技术,分析了内嵌业务逻辑子系统在软交换设备中提供业务的能力和特点,以及与其他子系统的接口关系。提出了一个内嵌业务逻辑子系统框架结构的设计方案,方案主要描述了ESL的模块划分、模块功能、模块间关系和模块间接口。
The paper provides the definition of Embedded Service Logic Subsystem (ESL). It describes the system composition ot softswitch equipment which takes the "service separating from call control" as one of the typical features. The paper also provides the basis and relative technology of ESL and analyzes the capability and features for service provision of ESL in softswitch equipment, and the interfacing with other subsystems on Softswitch. At the same time, the paper presents a framework design of ESL, which mainly describes the division, fhnctions of ESL module, as well as the relations between different modules and module interfaces.
