确定支持CTM所需的功能和体系结构。特别是，建议研究以下方面:-确定支持CTM的功能架构；-确定支持CTM的新FE和参考点（如有）；-确定现有IN-CS1/2 FEs的附加功能（如果需要）。在第二步中，分析可以包括其他方面，例如:-与其他网络互通的要求；-管理方面；-等

Identify the necessary functionality and IN architecture to support CTM. In particular it is proposed to study the following aspects: - Identify the functional architecture for the support of CTM; - Identify the new FE and Reference Points for the support of CTM in IN (if any); - Identify the additional functionality to the existing IN-CS1/2 FEs (if required). In a second step the analysis could include other aspects as for example: - Requirements for interworking with other networks; - Management aspects; - etc.
