Chen Jin-quan · Journal of Jinling Institute of Technology · 2008
This article mainly discusses the design of MGCF in interworking between 3GPP IMS and PSTN.Firstly,it discusses the function requirement of MGCF,bases on this,it gives a design idea,defines the main data structure and function.Then it designs main function modules.At the end of this article it gives the message conversion chart among processes in the function modules and clarifies the important idea of conversion between SIP and ISUP.Thus it realizes the main design of MGCF.
