The SS/USSD code is from a time where none of knew much about GSM. We do not support SS but should reject it. We have checked for an empty string in the text field to guess if it is a result/release to not send more information. The right way forward is to decode the ASN1 into the fields REQUEST/RESULT(last). Fix an issue and make the code worse. Assume ss_code > 0 to see if this is a interrogate invoke. The issue is that code 0 is a well defined value but unlikely to be used. MAP ASN1 definition: SS-Code ::= OCTET STRING (SIZE (1)) -- This type is used to represent the code identifying a single -- supplementary service, a group of supplementary services, or -- all supplementary services. The services and abbreviations -- used are defined in TS 3GPP TS 22.004 [5]. The internal structure is -- defined as follows: -- -- bits 87654321: group (bits 8765), and specific service -- (bits 4321) allSS SS-Code ::= '00000000'B Change-Id: Ib0dc4485388f030eb172fe21f5327b7ab94751f5 ----------------------------------------------------------------------- Summary of changes: openbsc/include/openbsc/gsm_04_80.h | 4 ++-- openbsc/src/libmsc/gsm_04_80.c | 4 ++-- openbsc/src/libmsc/ussd.c | 24 ++++++++++++++++-------- 3 files changed, 20 insertions(+), 12 deletions(-) hooks/post-receive -- The OpenBSC GSM Base Station Controller (+MSC/HLR/SGSN)
