Agenda

• TC INT Main Competence

• TC INT Main Deliverables

• TC INT Vision towards emerging networks and 5G

TC INT Vision towards 2020TC INT members use standardization to drive technology, to get knowledge about market trends to lay ground for future business with the required knowledge for implementation.

Co-operation between network players leads to increased revenues and time to market reduction due to Interoperability of systems and products developed and tested against technical specifications written by industry and Conformance and Benchmarked against Key Performance Indicators.

TC INT Vision towards emerging networks and 5G

5G will be the next major phase of

mobile telecommunications standards

beyond the current 4G standards.

Pre-standardization PoC will provide

feedback to the entire eco-system to

standardize future networks.

3GPP TS 23.501 is starting addressing

5G architecture

Interoperability and testing of 5G

standards will ensure network

optimization and Quality of Service

(QoS) and Quality of Experience (QoE)

from an end-user’s perspective.

TC INT Vision towards emerging networks and 5G

• Bringing forward testing methodology joining Quality of Experience (QoE) and Quality of Service (QoS)

• Drafting Test specification for 5G (new core networks as combination of NFV and SDN, self-organization, self-configuration, self-optimization, self-adaptive to dynamic traffic conditions and applications)

• Organization of Plugtest events for 5G

EG 203 341 Approaches for Testing Adaptive Networks

Published in June 2016

Definition of a framework of testing principles and guidelines that may be

used to test networks that exhibit autonomous, adaptive behavior, which

allows them to dynamically change their configuration, structure or

operational parameters.

Focus on scenarios where adaptive elements or functions are deployed in

a network, in various combinations, producing an environment that cannot

be characterized by traditional static and dynamic conformance

requirements.

The document concentrates on methodologies to test adaptive networks

towards meeting their functional targets or policies, and ensuring a

minimum trust level for autonomous operation of the Adaptive Network

(AN).

SecurityRobustness and reliability of BIG DATA, Cloud systems, and digital

commerce require secure of private and confidential user data.

Interoperability and conformance testing of protocols and interfaces for

the Applications Servers, IP Networks, IP Transport belonging to Core

Network elements.

vEPC Testing• Comprehensive testing of vEPC solutions

• New methodology, starting from the current end-to-end EPC testing solutions and including the specific metrics resulting from the software deployment on top of common hardware infrastructures through virtualization.

• The methodology will extend both the measured metrics towards the relevant cloud environments

• Test specification will be defined, including a set of tests which cover cloud specific functionality such as scaling and resilience, along with the performance tests.

Contributions of on-going work

• Conformance and interoperability for 4G services based on 3GPP specifications

– (VoLTE/ViLTE/VoWiFi, RCS)

• GSMA profiles– VoLTE, ViLTE, …

• IoT Connectivity

• Internet speed measurements

• Key Performance Indicator– Quality of experience

– Quality of service
