Meaning for Telecommunication
 Telecommunication is an infrastructure for dealing with Big Data
 Telecommunication itself is in a Big Data environments
(network and service systems generate Big Data as well)
 Followings should be considered:
 Data itself has least value
 Telecommunication is more than delivery (service/appl.)
 Delivery of data also less value, more value for services and
applications (involve as Big Data service/appl. provider)
 Value increased: Data  Information  Knowledge
 Become information based from data: need to handle “context”
 Move forward to knowledge based: need to deal with “meaning”
• Big Data infra provider: collection and delivery (incl. store)
• Big Data service provider(???): processing (analyze and
transform to information)
• Dealing with Big Data is a chance to improve telecom
capabilities for “Information and knowledge”
• Using “context” based on Big Data and strengthen
virtualized capabilities such as Cloud Computing

SG13 (1)
 Study and develop Cloud Computing (CC)
Recommendations:
 Y.3501: CC framework and high-level requirements
 Y.3510: CC Infrastructure Requirements
 Y.3520: CC framework for end to end resource mgmt.
 Y.3511: Framework of inter-CC for network & infrast.
 Y.3503: Requirements for Desktop as a Service
 Big Data study initiated by Y.BigData-Reqts (Req. and
capabilities for CC based Big Data) with following scope:
 Overview of CC based big data inc. introduction to big
data
 Big data characteristics, functionalities & relationship
with CC
 Benefit of CC based big data from telecom
perspectives
 CC based big data requirements, capabilities, use
cases and scenarios

SG13 (2)
 Study and develop Recommendations on “Context”
related based on Smart Ubiquitous Networks (SUN):
 Y.3041: Smart Ubiquitous Networks - Overview
 Y.3042: SUN - Smart Traffic Control and Resource
Management Functions
 Y.3043: SUN - Context awareness framework
 Y.3044: SUN - Content awareness framework
 Y.3045: SUN - Functional architecture of content
delivery
 Study and develop Recommendations on “Virtualization”
related for Future Networks:
 Y.3300: Framework of Software-Defined Networking
(SDN)
 Y.3012: Requirements of network virtualization for
Future Networks
