摘    要:Parlay/OSA(Open service access)网关的主要功能之一是实现各种电信协议到Parlay/OSA API的映射。OMG的CORBA/TC Interworking规范给出了使用TC/SS7的通信实体与基于CORBA的实体交互的建议,因为大部分的Parlay/OSA网关是基于CORBA实现的,因此该规范对协议映射的实现具有重要的参考价值。在深入理解TC—CORBA规范的基础上,提出了一种Parlay/OSA网关中协议映射实现的一种模式。重点描述了模式的主要体系结构和工作流程,分析了其特点。此模式对Parlay/OSA网关产品中协议映射的实现具有重要的参考价值。

关 键 词:Parlay/OSA网关  TC—CORBA规范  协议映射  模式

Abstract:One of the key functions of Parlay/OSA(open service access) gateway is mapping telecommunication protocols in Parlay/OSA API.3GPP TR 29.998 serial specifications specify mapping methods and parameters between protocols such as CAP,MAP,SIP and Parlay/OSA API,but how to implement it is not mentioned.OMG CORBA/TC interworking and SCCP Inter-ORB Protocol Specification give an implementation model of interworking between TC/SS7 based entities and CORBA based entities.Because most Parlay/OSA gateways are implemented on CORBA,implementation of protocol mapping in Parlay/OSA gateway can learn much from CORBA/TC interworking model.Based on the comprehensive understanding of the TCCORBA specification,a pattern of implementation of protocol mapping in Parlay/OSA gateway is proposed.The architecture and work scenario of the pattern is described and its characteristics are analyzed as well.Those who will implement protocol mapping in Parlay/OSA gateway will benefit from this pattern.
Keywords:Parlay/OSA gateway  TC CORBA specification  protocol mapping  pattern
