5     Highlights of WP1/11, WP2/11 and WP3/11 meetings

WP1/11
WP1/11 finalized text and finally consented one new draft ITU-T Recommendation ITU-T Q.3741 (ex. Q.SD-WAN) “Signalling Requirements for SD-WAN service". It specifies signalling requirements for SD-WAN service launched by service providers. The signalling is to support the automated provision and management of the enterprise SD-WAN service.
Note: SD-WAN is an ecosystem of hardware, software, and services that enable service providers to launch Software-Defined WAN service for enterprises. It provides high quality WAN performance, reliability, and security in various ways.
WP1/11 agreed one new Supplement 70 to ITU-T Q-series Recommendations (ex. Q.suppl.Multi_Device_ETS) “Signalling requirements for IMS and GSM/UMTS network supporting multi-device emergency telecommunications service".
WP1/11 agreed to initiate a new work item of a technical report for improvement of SS7 security based on the draft technical report presented at the Q2/11 meeting. The goals for this work item are to promote the standardization on security mechanisms for existing (e.g. Legacy, 2G) and future networks, to research on the measures which could reduce the implementation cost of SS7 security in 2G networks, to provide concrete material for education to telecom and financial services regulators on SS7 vulnerabilities and mitigation measures for DFS, and to mitigate the use of the SS7 vulnerabilities for financial fraud.
Following this outcome, it was proposed to organize a brainstorming session on SS7 security (Workshop) during the next SG11 meeting (22 October 2019, Sessions 3&4). The announcement will follow and the details of the event will be circulated through the mailing lists of SG11 accordingly.
The WP1/11 agreed with the updated text of the ongoing work items which were considered during Rapporteur group meetings (Geneva, 17-26 June 2019), as follows:

WP2/11
WP2/11 finalized text and finally consented one new draft ITU-T Recommendation ITU-T Q.5021 “Protocol for managing capability exposure APIs in IMT-2020 network". It includes signalling architecture, API management functions, signalling flows and their message format, and definition for management APIs. It also describes gap analysis and use cases for API management. This protocol can be used by network operators and third parties to manage capability exposure APIs.
The WP2/11 agreed with the updated text of the ongoing work items which were considered during Rapporteur group meetings (Geneva, 17-26 June 2019), as follows:

WP2/11 appointed Ms Tangqing LIU (China Mobile, China) as a new Associate Rapporteur for Q6/11.
WP2/11 approved the reports of the interim Rapporteur meetings of Q6, 7, 8/11 accordingly.
During the WP2/11 meeting, it was highlighted that most of the Questions started the reconsideration of the ToR for the next Study Period. Therefore, all SG11 members were encouraged to provide relevant proposals to the next SG11 meeting (Geneva, 16-25 October 2019).

WP3/11
WP3/11 finalized text and finally consented one new draft ITU-T Recommendation ITU-T Q.4043 “Interoperability testing requirements of virtual switch" which introduces the overview of vswitch and interoperability testing of vswitch, which includes but is not limited to the definition, characteristics, general capabilities of vswitch as well as the overview of interoperability testing of vswitch.
The WP3/11 agreed with the updated text of the ongoing work items which were considered during Rapporteur group meetings of Q10, 13 and 14/11 (Geneva, 17-26 June 2019), as follows:

The Chairman of WP3/11 introduced a contribution to propose a test methodology for IP reachability (SG11-TD41/WP3). This contribution was addressed to Q9/11, Q10/11 and Q12/11. During interim Rapporteur Q12/11 e-meeting, which takes place in parallel with SG11 RGM, Q12/11 agreed to consider this proposal for the future revision of one of their on-going work items.
Due to other commitments, the Rapporteur of Q14/11 Mr Nan CHEN (China Telecom, China) would step down. Mr Chen was thanked for his work with ITU-T SG11. Mr Xiaowu He (China Telecom, China) was appointed by WP3/11 as a new Rapporteur of Q14/11.
WP3/11 approved the reports of the interim Rapporteur meetings of Q10, 13, 14/11 accordingly. It was noted that the reports of the Q9, Q12 and Q15/11 e-meetings will be considered at the SG11 meeting (Geneva, 16-25 October 2019).
