Hi Romeu, First, thank you for helping to improve NextEPC. Of course, I also do not have a pcap file related to CSFB. However, I've re-designed the socket library so that you can easily implement this function. In the new socket library, you only need to create sgsap-path.c. The common part of the remaining SCTP is handled by ogs-sctp.c. Please let me know if you want to access github directly. Of course, you can use the pull-request method. Use the convenient method. Please feel free to contact me if you have any questions. Thanks a lot! 2019년 6월 1일 (토) 오전 9:11, Romeu Medeiros <medeiros(a)medeiros.eng.xn--br>-n54x791j 작성:

Hi Sukchan and Romeu, we are running an automated test suite for the SGsAP interface of OsmoMSC. In this situation, the test suite implements/emulates the MME side. The test source code can be found in osmo-ttcn3-hacks.git on git.osmocom.org, specifically in the 'msc' subdirectory. However, you don't need to run the test suite to get access to the pcap files, as our jenkins continuous integration server is publishing a pcap file for each and every test case that gets executed every night. You can e.g. find the results of todays build at: https://jenkins.osmocom.org/jenkins/view/TTCN3/job/ttcn3-msc-test/561/artif… you will liekely be interested in the MSC_Tests.TC_sgsap_*.pcap files like https://jenkins.osmocom.org/jenkins/view/TTCN3/job/ttcn3-msc-test/561/artif… Please feel free to keep Philipp and/or me in Cc. Philipp is the developer implementing the MSC side of SGsAP in Osmocom.
