�In particular, the report will include thorough

analysis of ATIS SON’s WG documents and provide recommendations as to which specific

work items can be carried out within GISFI and

the work items that can complement the work items within SON.

�Gap analysis at Network infrastructural level

Deliverable (3/5)

Slide 15© GISFI

Task 4: Security Models

Rapporteur: TCS

analysis document.

�In particular, the security task group will look at the following

� Ongoing security work within 3GPP (e.g., security and

identity aspect as single-sign-on) and will conduct a

study on how security, identity and location thing will

work together.

� Security for Cloud Computing

�The task group will clarify requirements for rural India

Deliverable (4/5)

Slide 16© GISFI

Task 5: Information Management :

Rapporteur: MPHASIS

Contributor: NIKSUN


�Information migration is beginning to play an

important role as there is a gradual shift towards

convergence of IT and Telco taking place.

�MPHASIS will study a few set of information

models as defined in TM Forum and will take into

account a specific application such as wireless number portability (WNP).

�The deliverable format could be a word document

and set of annotated view graphs.

Business Model – An opportunity for Providers

� Emergence of a new group of services are different from traditional Telco� Traditional forms of communication are being displaced with

message-based interactions around social community

� Technologies, development practices and business models are markedly different between Web 2.0 and IMS

� Business model based on supporting Web 2.0 application over an IMS platform can benefit � end-users, service providers, and third party application

developers

� Convergence among Web 2.0, service oriented architecture and IMS call control features� Web 2.0 provides interactivity, ubiquity, social orientation and

user participation

� IMS provides a platform to complete service features with multimedia telephony, media sharing using call control features and support for security, user authentication, quality of service

�NIKSUN represented GISFI SeON during October ATIS SON meeting in Washington DC

�ATIS shared their work plan document for GISFI members

�Cloud computing is now part of SON

�Dialogue in progress to have an official collaboration with ATIS

�GISFI as an affiliate member

�User experience matters� Content and collaboration service components enrich user

experience on the top of communications and sessions

�Service deployment and operation is critical to establish new business models� Interoperable service enablers bring strong deployment and

operation properties in order to guarantee QoE across

domains

� IMS brings interoperable roaming, authenticated multimedia

calls, subscriber, network and device authentication

�SOA principles to ensure strong S/W principles lead to maximized quality/cost� SDP/SoA brings open networks to web 2.0 enabling flexible

reuse of service capabilities 7 33
