Agenda Workshop#31 – open Action 31.3: TF160: To provide status update on IMS re-transmissions and Big Grants. RTP/RTCP loopback – R : follow-on discussions on the two alternatives. IMS GBA (Anritsu): Different IP address / port number for BSF server? TTCN CRs reservation system: migration to 3GU.

Workshop#31 – open Action 31.3 Action 31.3: TF160: To provide status update on IMS re- transmissions and Big Grants. Confirmed that: In test cases with default IMS handling (i.e. no test case specific IMS behaviour) we have a TTCN default handler which in case of unexpected IMS messages (e.g. SIP re-transmission) just discards them. © ETSI All rights reserved

RTP/RTCP Loopback – R R was discussed Tuesday morning in the RAN5 SIG session. RAN5 endorsed that two possible ways forward will be discussed further, with a final decision being taken by the end of RAN5#69: A. Keep the current test model with clarifications in TS prose. B. Alternative test model based around TTCN socket emulation. Questions on AlternativeB? © ETSI All rights reserved

TTCN CR Tdoc number reservation system – Status Update Current status: ETSI ADN system still in use for TTCN CRs for both RAN5 (R5s15xxxx) & GERAN3 (G3t15xxxx). 3GU migration plans: When: Plan is to start using 3GU right after TSG RAN#70, i.e. week starting 14 th December TTCN CRs reservation will use 3GU (same as RAN5 prose CRs). RAN5: R5s16xxxx. GERAN3: H1’16: G3t16xxxx. H2’16: R5s16xxxx (GERAN3 merged into RAN5). Further details TBC. © ETSI All rights reserved

Any idea on the cause(s)? Is it because the required GSM/GPRS features are typically not implemented/deployed? (e.g. PS HO?) Should those TCs be added to iWD-003? © ETSI All rights reserved
