arah pengembangan core network architecture (indonesia)

Mobile OperatorNetwork Evolution

Let’s start with Questions

•What is the existing condition of CSP’s core network?

•Does CPS already have their future direction for its core network evolution?

•How does CPS view on Indonesia telecom market needs?

CSP Focus•Market needs and growth•Low cost CAPEX and OPEX•New services for the market to boost revenue•Fast time to market of new products and

services • Infrastructure readiness for future market

and technology trend •Utilize current infrastructure

How to achieve above considerations, and what is the suitable network architecture?

Latest Telecom Technology

•What are the hottest current telecom & IT technology?

▫IMS, SDP▫LTE/SAE▫Telco 2.0, WEB 2.0▫Cloud computing

FMCNGN

GSM Mobile Network Evolution

•GSM, GPRS, EDGE, UMTS, HSDPA, SDP, IMS, HSUPA/HSPA, HSPA+, Common IMS, LTE/SAE/EPC, LTE-Advanced

Enhancement Focus▫Radio Access

Faster Data rates Decreased Latency High Cell Edge Throughput Spectrum Flexibility

▫Core Network Access independence for services Standardized multimedia services Mobility and IP interworking for all accesses

▫Service Layer Any Service (Ease of development) Any device Anywhere (Exposing core network capability)

Technology Adoption

•How CSP adopt the technology?▫Vendor/Consortium driven▫Standard driven▫Market driven▫Hype vs. reality

?

Network Architecture Direction

•Facts in Indonesia:▫Current Core Network Architecture used in

CSP in Indonesia is 3GGP R4▫IMS is next generation network

architecture for PSTN, broadband, LTE/EPC, cable television

▫Some region already support HSDPA/HSPA

•Plan:▫Implement IMS coexist with CS domain

IMS Top Questions.• What is IMS?• Why we need IMS?• How IMS interworking with other PLMN, PSTN?• How IMS relate to LTE/EPC?• What is an IMS device?• What is the IMS killer application?• How QoS of VoIP in IMS?

IMS Business Challenges

1. Developing a business plan with near-tem ROI2. Merging/managing IT, network operations and

marketing3. Device availability4. Competing against free services (portal voice,

video, etc.)5. Unknown legislation (net neutrality)6. Developing killer apps7. Intercarrier interconnection8. Understanding the business of alliance partners9. Timing (thinking big but starting small)

Sample issue need to be solved regarding IMS implementation

Intercarrier interconnection issue•Some possibilieties:

▫Using Internet connection▫Direct connection using leased lines▫Using GRX (GPRs Roaming eXchange)

networks▫Using IPX networks

SOLUTION:•Propose to regulator to build one national

IPX operator

What next?
