6     Second meeting of the ITU-T Conformity Assessment Steering Committee (CASC)
The second meeting of the CASC was addressed in two sessions on Tuesday 28 June 2016 from 9:30am and was chaired by Mr Isaac Boateng.
The CASC established an initial list of ITU-T Recommendations (ITU-T P.1140, P1100, P.1110 and K.116) which may become subject of joint certification schemes. For such joint certification programmes, the CASC aims at establishing collaboration with the International Electrotechnical Commission (IEC) for ITU-T P.1140 and K.116 and with the Global Certification Forum (GCF) for ITU-T P1100 and P.1110.
While detailed procedures involving the GCF are yet to be discussed, the IECEE has submitted a Contribution to inform on the decision of the IECEE Conformity Assessment Board (CAB) and Certification Management Committee (CMC) on establishment of an ITU-T/IECEE joint Task Force, which will be tasked to define the ITU requirements necessary for the inclusion of a testing laboratory and joint certification program.
The meeting report can be found in TD 1306 (GEN/11). More details about ITU-T CASC is available at https://itu.int/en/ITU-T/studygroups/2013-2016/11/Pages/CASC.aspx. 

7     Collaboration with ETSI TC INT
According to the approved guideline TD 913 (GEN/11), outlining a framework for collaboration among SG11 and ETSI TC INT, a co-located meeting of ETSI TC INT was organized in Geneva from 28 June to 1 July 2016. It allowed organization of joint sessions among relevant Questions of SG11 and ETSI TC INT to progress topics of joint interest including:
–      SIP-IMS conformity testing (joint with Q11/11);
–      Internet speed measurement (joint with Q15/11);
–      Framework of an interconnection among VoLTE/ViLTE-based networks (joint with Q2/11).

8     Combating counterfeiting
SG11 Q8/11 advanced the draft Recommendation "Framework for solution to combat counterfeit ICT Devices", which will be approved via TAP, based on Contributions from Brazil, and UK. The updated draft Recommendation is to be found in TD 1337 (GEN/11). The two ongoing technical reports TR-CF_BP "Guidelines on best practice and solutions for combating counterfeit ICT devices" TD 1346 (GEN/11) and TR‐Uni_Id "Use of anti-counterfeiting technical solutions relying on unique and persistent mobile device identifiers" TD 1230 (GEN/11) were also progressed at the meeting. A new work item SR-AFR "Survey report on counterfeit ICT devices in Africa region" TD 1199 (GEN/11) has been agreed and is planned for approval at next SG11 meeting.
A contribution from Russia proposing to create a new work item on "DoA-IoT-based ICT system to combat counterfeiting" was not accepted. Russia was advised to resubmit this proposal with a more generic scope, e.g. proposing a generic solution using IoT; DOA may be listed as one of the solutions in such a generic framework.

9     Internet speed measurement
After AAP comment resolution, see its report TD 1186 (GEN/11), the new Recommendation ITU-T Q.3960 "Framework for Internet related performance measurements" (ex. Q.FW_Int_sp_test) was approved, final text in TD 1345 (GEN/11). This marks an important achievement as this framework targets internet speed measurement from an end-users perspective. A companion draft Recommendation (planned Q.3961) on "Testing methodologies of internet speed measurement system to be used on the fixed and mobile networks" will be progressed at next meeting of SG11, which plans continuing developments in this area. To be noted that this is a joint work with ETSI TC INT.

10     Other Conformance and Interoperability (C&I)-related outcomes
SG11 advanced and updated the standardization work plan for SIP-IMS as 20 new Recommendations were approved on SIP‐IMS, TD 1343 (GEN/11). It includes standards of requirements and relevant test specifications of basic call and some supplementary services, which are applied to fixed networks. SG11 collaborate with ETSI TC INT on this subject.
WP4/11 has progressed work on C&I issues. Relevant updates are provided as follows:
–     Pilot projects for conformity assessment against ITU-T Recommendations TD 1326 (GEN/11), http://www.itu.int/go/pilot-projects);
–     Living list of key technologies which are suitable for C&I Testing (TD 1235 (GEN/11), http://itu.int/go/key-technologies);
–     The reference table of standards used for C&I assessment (TD 1255 (GEN/11), http://itu.int/go/reference-table);
–     A new Recommendation ITU-T Q.3920 "Terms and definitions to be used in Conformance and Interoperability issues" was consented. It will help to enhance discussions on C&I by providing a common terminology;
–     For the CASC results, see section 7.
The Joint Coordination Activity on Conformance and Interoperability (JCA-CIT) was closed as it achieved its objectives. Future coordination on C&I will be performed by SG11 in its capacity of Lead SG on test specifications, conformance and interoperability testing. 

11     Establishment of two regional groups for SG11 (Africa and RCC)
At the last meeting of SG11, two regional groups were established, one for Africa and one for RCC. These regional groups were supported by both ATU and RCC. The terms of references of these two new regional groups can be found in TD 555 (TSAG).

12    Workshops during SG11 meeting (27 June – 6 July 2016)
12.1  Combating Counterfeit Using Conformance and Interoperability Solutions
A workshop on "Combating Counterfeit Using Conformance and Interoperability Solutions" was held on 28 June 2016 (PM) and was attended by about 100 participants. The workshop succeeded in creating awareness of the studies currently on-going in ITU-T SG11 Question 8 on the topic to combating counterfeit. It debated whether or not conformance and interoperability programmes can assist to combat counterfeit ICT devices, and provided best practices worldwide. It also showcased new trends and mechanisms in ICT counterfeiting, tempering and/or duplication of unique device identifiers and discussed mechanisms to secure the supply chain management (from manufacturing, importation distribution and marketing) to ensure traceability, security, privacy and trust of people, products and networks. A Chairman report was posted on the workshop webpage and can be seen here.

12.2  SS7 Security
A workshop on "SS7 Security" was held on 29 June 2016 (AM) and was attended by about 100 participants. This workshop succeeded to share information on SS7 security issues among various operators and stakeholders. It analyzed the current SS7 standards and identified which one is impacted as well as how to improve them in terms of security. The workshop also discussed cooperation with other SDOs and organizations on SS7 security issues. A Chairman report was posted on the workshop webpage and can be seen here.
