对接 集成 IMS
Executive Summary Objective To create an open source test bed for validating th e end to end VOIP calls originating or terminating at 3G/4G mobile network for use cases like PSTN-IMS an d IMS-PSTN call flows. • Conformance to the 3GPP IMS standards using open s ource elements which can provide advantages like Standard conformance Negligible cost Potential for wide usage across different 3G/4G te chnologies Approach © Nokia Siemens Networks • Selection of the open source softwares to emulate IMS and PSTN gateway functionalities. • Integration of the above components into the test bed which enables the testing of Mobile-Mobile (M-M), Mobile to Land (M-L) and Land to Mobile (L-M ) VOIP calls. Results Availability of cost effective test solution for va lidation of end to end VOIP calls for M-L, L-M and M-M scenarios
