ttcn3: more than one BSC

I'm trying to test inter-BSC Handover in ttcn3. At first I had problems grasping the concepts, but in the end it worked pretty nicely to start two distinct BSC handlers like this: testcase TC_ho_inter_bsc() runs on MTC_CT { var BSC_ConnHdlr vc_conn0; var BSC_ConnHdlr vc_conn1; f_init(2); vc_conn0 := f_start_handler(refers(f_tc_ho_inter_bsc0), 53, 0); vc_conn1 := f_start_handler(refers(f_tc_ho_inter_bsc1), 53, 1); vc_conn0.done; vc_conn1.done; } It's walking all the way through inter-BSC Handover now (!) up until the point where I want to discard the call. Now I'm facing the simple problem that I want to call f_call_hangup() in the second f_tc_ho_inter_bsc1() -- but I have no cpars (CallParameters) with a valid MNCC callref nor the CC transaction ID, those are in the first function. How can I share cpars between those functions? The transaction_id and callref determined by the MNCC and CC messages that happened in f_tc_ho_inter_bsc0 need to move over to f_tc_ho_inter_bsc1, much like the MS has moved to the other BSC. So it would make sense to have some global struct representing the MS which both BSC_ConnHdlr instances can access, if that is at all possible ... ? As a bit of a weak workaround, I could inter-BSC handover right back to the first BSC and then f_call_hangup() there :P ~N -- - Neels Hofmeyr <nhofmeyr(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Alt-Moabit 93 * 10559 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschäftsführer / Managing Directors: Harald Welte
