7     Action plan of ITU-T SG11 for the new Study Period (2017-2020)
During the first meeting of SG11 (February 2017), the SG11 Chairman presented the SG11 Action plan (SG11-TD173/GEN) which summarizes the strategy of the WPs for the current Study Period, according to the presentations given by the WPs Chairmen.
At the SG11 meeting (8-17 November 2017), the SG11 Chairman encouraged the WPs Chairmen to provide updates to the action plan at the next SG11 meeting (July 2018).

8     SDN and 5G/IMT-2020 related issues
SG11 finalized set of new ITU-T Recommendations dealing with SDN and other 5G related technologies. Among them were: ​All of the above new Recommendations were consented at the closing plenary of SG11 meeting (17 November 2017).
SG11 also advanced the ongoing work item Q.NS-LCMP “Protocol for network slice lifecycle management” and agreed to start several new work items on IMT-2020, as follows: ​More information on these activities is available in the WP1/11 and WP2/11 reports accordingly (SG11-TD346-R1/GEN, SG11-TD347-R1/GEN).

9     Signalling issues
SG11 consented the revised Recommendation ITU-T Q.1912.5 "Interworking between Session Initiation Protocol (SIP) and Bearer Independent Call Control protocol or ISDN User Part" and advanced ITU-T Q.3405 "IPv6 protocol procedures for broadband services".

SG11 also agreed to start a new work item Q.ETN-DS "Signalling architecture of the fast deployment emergency telecommunication network to be used in a natural disaster" which aim is to describe the functional elements, services and signaling architecture of emergency telecommunication network which can be rapidly deployed in a country affected by a natural disaster.

10     SS7 security
SG11 meeting discussed number of contributions addressed to SS7 issues. Among them were proposals to revise ITU-T Q.731.3 and create new signaling procedures to be applied on SS7 stack.
With regards to Q.731.3, following the discussion, delegates reached consensus on the following procedure for generic number: In the local exchange, Generic number parameter indicating "additional calling party number" with the screening indicator "user provided, not verified" shall not be sent without service agreement.
Following the discussion of the proposed new work items, meeting agreed that verification of the identification of network entities (also the calling party number) is a very important method to achieve greater safety and security for network. At current stage, study on the requirements and architecture for interconnection between trustable network entities is needed. In this regards, it was agreed to start a new work item Q.SR-Trust "Signalling requirements and architecture for interconnection between trustable network entities".
More details are available in WP1/11 report and Q2/11 report accordingly (SG11-TD346-R1/GEN, SG11-TD332/GEN).

11     VoLTE/ViLTE interconnection
Following two years of study, SG11 consented two new ITU-T Recommendations dealing with VoLTE/ViLTE interconnection, as follows:

​Following this result, SG11 agreed to start a new work item Q.DEN_IMS “Signalling architecture of distributed ENUM networking for IMS” which will define the signalling architecture of distributed ENUM networking in support of IMS interconnection. Even though this new work item will focus on signalling aspect, it was decided to start this new work item with an approval process of TAP.
SG11 also made progress on ongoing work item Q.suppl.Multi_Device_ETS “Signalling requirements for VoLTE-based network and GSM/UMTS network supporting Multi-device emergency telecommunications service” and agreed to start several new work items on VoLTE/ViLTE matters, as follows: ​The details are available in WP1/11 and WP3/11 reports accordingly (SG11-TD346-R1/GEN, SG11-TD348/GEN).

12     Fifth meeting of the ITU-T Conformity Assessment Steering Committee (CASC)
SG11 approved the revised Terms of Reference (ToR) of CASC, which were aligned with WTSA-16 Resolution 2 and Resolution 76 referring to joint ITU/IEC certification scheme.
CASC discussed the collaboration approach with IECEE TF in order to establishing joint certification scheme. It was agreed that the Chairman will contact the representatives of IEC asking them to provide their inputs to the ongoing CASC’s guidelines for consideration at the next CASC meeting.
CASC also updated list of focal points of ITU-T SGs to CASC according to received inputs from ITU-T SGs.
The CASC agreed that it will meet again during the next meeting of SG11 (20 July 2018) (TBC). Also, it was agreed that CASC will use its mailing list t17sg11casc@lists.itu.int as a useful tool to facilitate discussion between its members to progress the work of CASC. It also can be used for exchanging some inputs and ideas related to the ongoing work items, which might become contributions to the next CASC meeting.
The meeting report can be found in SG11-TD329/GEN. More details are available on the ITU-T CASC web page.

13     Implementation of ITU C&I Programme
According to inputs received from ITU-T SGs, ITU-T SG11 updated the reference table of ITU-T Recommendations suitable for C&I testing. The information was updated on the ITU C&I Portal accordingly (see www.itu.int/go/reference-table).

14     Internet related performance measurements
SG11 discussed the draft ITU-T Q.3961 "Testing methodologies of Internet related performance measurements including e2e bit rate within the fixed and mobile operator's networks". In spite of achieved progress and bearing in mind the received LS from SG12, SG11 decided to put draft ITU-T Q.3961 on hold for the time being. The SG11 will return to the draft ITU-T Q.3961 as soon as the relevant standard appears in other Standardization Bodies.
The meeting report can be found in SG11-TD339/GEN.

15         Collaboration with ETSI TC INT
SG11 continues collaborating with ETSI TC INT through current joint activities and some new areas. Among current joint activities are: ​The next joint meeting of Q9/11, Q11/11 and ETSI TC INT is scheduled to take place in Prague (hosted by University of Prague) from 20-22 March 2018. All details are available on the SG11 web page.
