Service Platform for Mobile Internet

Japanese

Highly dependable and one of the largest service delivery platforms on which i-Mode operates. [ 04:50 ]

Movie script

The i-mode mobile internet service offered by the Japanese telecommunications company NTT DoCoMo is a marvel of modern technology.
Required to serve e-mail and web access traffic at speeds of up to 75,000 packets per second, it is one of the world's most heavily used mobile data services.
Demand skyrocketed after i-mode was launched in 1992, and by 2006 NTT DoCoMo was listed in the Guinness Book of Records as the world's largest mobile internet service provider. As of 2008, the company has some 47 million subscribers, and its i-mode service has become interwoven into the social and business fabric of Japanese life.

THE CHALLENGE

Subscribers of i-mode rocketed immediately after its launch on February 22nd, 1999.
At the end of 2000, looking towards the future and aiming to further establish the reliability of the i-mode service, NTT DoCoMo decided to reconstruct a far-reaching new system that would change everything – the architecture, hardware and program.

AKIHIKO AOYAMA Managing Director , Platform Development Department , NTT DoCoMo,Inc. :
This system is required to manage tens of thousands of transactions per second and needed to be operated around the clock, 365 days a year.
We only had one year to create a system that met these requirements.

THE SOLUTION

NEC joined forces with NTT Data as the overall system integrator, in order to construct the world’s largest gateway system.
The project pushed ahead in conjunction with the venders Cisco, EMC, Foundry Networks, HP and Oracle and in the short period of just two years after the start of development, i-mode’s new service platform CiRCUS was born.

THE TECHNOLOGY

As the service construction of CiRCUS commenced, NEC proposed the very latest open mission critical system making durability and flexibility possible.
CiRCUS, one of the largest systems in the world, was constructed by a combination of optimum solutions from among global standard technologies and products, such as the NX7000 series, NEC’s UNIX server.

TAKAYUKI ITOH Senior Manager , Senior Manager , Platform Development Department , NTT DoCoMo,Inc.:
The i-mode service deals with over 75,000 transactions per second including e-mails and web access services. These need to be handled smoothly and without delay.
Plus, the enlargement and strengthened functions of new services is a constant requirement , and has to be implemented in CiRCUS(system) without stopping regular services.

In order to maintain the stable i-mode service so that subscribers can use 24 hours a day, 7 days a week, we built a more solid and steady structure. For example the i-mode back up center which carries the same functions as the main center and the 24 hour surveillance operation center CARNiVAl.

THE BENEFITS

TAKAYUKI ITOH Senior Manager , Senior Manager , Platform Development Department , NTT DoCoMo,Inc.:
The target value for the availability of the CiRCUS system is 99.9999% as the very high percentage, compared with other nondisruptive Systems.
This means that the services stop only 30 seconds per year per customer. An astonishing figure.

In 2006, NTT DoCoMo was recognized by the Guinness World Records as the mobile internet provider with the greatest numbers of subscribers in the world.

AKIHIKO AOYAMA Managing Director , Platform Development Department , NTT DoCoMo,Inc. :
i-mode has expanded based on the concept of making mobile phones “more convenient and more entertaining,” and we are currently developing such services as "Osaifu-Keitai" through CiRCUS.
We have the highest regard for NEC, and we are hopeful of NEC’s ability to construct the Service Platform and maintain that.

Handling everything from planning and development to management and maintenance, NEC is making a major contribution to society through the construction of its service platform.

Service Platform for Mobile Internet Img

The i-mode mobile internet service offered by the Japanese telecommunications company NTT DoCoMo is a marvel of modern technology.
Required to serve e-mail and web access traffic at speeds of up to 75,000 packets per second, it is one of the world's most heavily used mobile data services.
Demand skyrocketed after i-mode was launched in 1992, and by 2006 NTT DoCoMo was listed in the Guinness Book of Records as the world's largest mobile internet service provider. As of 2008, the company has some 47 million subscribers, and its i-mode service has become interwoven into the social and business fabric of Japanese life.

With society relying on the service so extensively, the need to prevent disruption became critical. Eventually, at the end of 2000, NTT DoCoMo decided to replace the entire system, deploying a new architecture, new systems, and new programs. Commenting on the decision, Akihiko Aoyama, Managing Director, Platform Development Department, NTT DoCoMo, Inc. said, “This system is required to manage tens of thousands of transactions per second and needed to be operated around the clock, 365 days a year.
We only had one year to create a system that met these requirements.”

NEC joined the project as a system integrator working with NTT Data for the development of a new platform. It was chosen for this vital role because of its wide experience in developing credible, large-scale telecommunication solutions, and for its expertise in Internet service integration and multi-platform system implementation. In addition to providing NX7000 series UNIX servers and other supporting hardware, NEC worked closely with vendors such as Cisco, EMC, Foundry Networks, HP, and Oracle to ensure maximum system reliability at every level.

Called “CIRCUS” one of the world’s largest brand-new platform which was constructed in a brief period of 2 years.
One of the strengths of the CIRCUS is its reliability.
After completing the transition of all i-mode services to the main center in 2003, a dedicated backup center was established so that reliability was further enhanced.
In addition to that, by the establishment of a round-the-clock monitoring operation center called "CARNiVAL.”, NTT DoComo enable to operate a system 24 hours a day, 365 days a year.

Another great strength of the CiRCUS is capability of handling 75,000 requests per second, it boasts world-class batch processing capabilities. Advanced load balancing technologies are deployed on every server to enable simultaneous processing of email, internet access requests, and the distribution of official website content.

Although servers have been increasing and demand for functional extension is high CiRCUS maintains its stability. Takayuki Itoh, Senior Manager, Platform Development Department, NTT DoCoMo, explains his team's numeric targets for service uptime: “The target value for the availability of the CiRCUS system is 99.9999%.as the very high percentage, compared with other nondisruptive systems.
This means that the services stop only 30 seconds per year per customer.
An astonishing figure."

"CiRCUS"゛means treasure Casket of i-mode service, high Reliability platform for CUStomer.

i-mode has expanded based on the concept of making mobile phones “more convenient and more entertaining,”and NTT DoCoMo are currently developing many services through CiRCUS.

NEC has accumulated its unique technologies over years. It is enabled with the fact that the company has been leading the market of “Open mission-critical system”, which realizes both reliability of 24/7, 365 days a year and flexibility to cope with changing market rapidly.
Applying its advanced platform construction, application development technologies and project management experience cultivated through the case of NTT DoCoMo, NEC will continue to contribute to society by enabling a wider range of services to reach a wider range of people.

"CiRCUS" is an i-mode gateway system.

"Osaifu-Keitai" is a registered trademark of NTT DoCoMo, Inc. in Japan.

"Osaifu-Keitai" refers to mobile phones equipped with contactless IC card, as well as its useful function/services enabled by the IC card.
With this function, mobile phones can be utilized as electronic money, credit card, electronic ticket, membership card, airline ticket, and more.
