pespin has submitted this change. ( https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/43895?usp=email ) Change subject: smf,pgw: Split GTPv2C S2b/S5/S8c create session into multiple func helpers ...................................................................... smf,pgw: Split GTPv2C S2b/S5/S8c create session into multiple func helpers This will be used by follow-up tests which want to trigger parts of the Create Session procedure. Modify PGW_Tests the same way to have similar code base (and because I wrongly started modifying it instead of SMF_Tests, so the work is done anyway ;) Change-Id: I07896c37d06014873b120f87457f99f529f4601a --- M pgw/PGW_Session_CT.ttcn M smf/SMF_Session_CT_4G.ttcn 2 files changed, 175 insertions(+), 104 deletions(-) Approvals: osmith: Looks good to me, but someone else must approve Jenkins Builder: Verified laforge: Looks good to me, but someone else must approve pespin: Looks good to me, approved diff --git a/pgw/PGW_Session_CT.ttcn b/pgw/PGW_Session_CT.ttcn index 146c3f2..f94192f 100644 --- a/pgw/PGW_Session_CT.ttcn +++ b/pgw/PGW_Session_CT.ttcn @@ -247,6 +247,21 @@ } } +function f_DIA_handle_create_sesion() runs on PGW_Session_CT +{ + var boolean do_s6b := is_s2b_iface();
