AT&T80 million subscribers

Background

AT&T is the largest telecommunications operator in the United States, with substantial business interests in mobile, fi xed line, IP and broadcast communications. CDRlive was initially implemented in 2004 as a performance measurement solution for Cingular Wireless, but rapidly grew to become the core data warehouse and reporting solution for the Network group. It has since experienced two signifi cant upgrades – once when Cingular bought the AT&T Wireless brand, and then again when AT&T acquired Cingular Wireless – taking it from a system that initially supported 22 million subscribers to one that currently supports over 80 million.

Today, the CDRlive system at AT&T has set new records in terms of size and performance:• The full system comprises 2 x 310 TB production

databases (Oracle 10g) and more than 1.2 Petabytes of raw storage.

• Each site loads an average of 4 billion rows per day (45,000 rows per second) and a peak of 15 billion rows per day (175,000 rows per second) in real time.

Business Usage

Simultaneous to the massive scale-out of the CDRlive system, it has also grown dramatically in terms of its usage across the enterprise. Today, the CDRlive system at AT&T is deemed a strategic EDW that services the needs of multiple business groups:

• Network: Network Usage, Traffi c Analysis, Capacity Planning, Fault Reporting, 2G/3G, Network Vendor Comparisons, Cluster/Market Views, MSC/Cell Level Reporting, Device Analysis, Non-CDR Network Reports (e.g., SS7, GPEH etc.), New Technology Testing and Launch.

• Marketing: Campaign Management, Customer Loyalty Programs, New Product Launch (e.g., Apple iPhone), New Service Launch (e.g., LTE), Competitive Analysis, Media Mix, Customer Experience Management, Churn Modelling and Prediction, Social Network Analysis.

• Finance & Legal: Revenue Assurance, Interconnect/Inter-Carrier Billing, Least-Cost Routing, Revenue/Profi tability Analysis, Fraud Investigation and Pre-vention, Law Enforcement and Emergency Services, Regulatory Compliance.

• Subscriber Management: Usage Patterns, Prepaid vs. Postpaid, Device Usage and Experience, Customer Experience Management, Enterprise Account Management, Work vs. Home Usage/Experience, Trouble-Shooting, Customer Care.

• Product/Service Management: New Product/Service Launch, Pre-Launch Testing and Evaluation, Post-Launch Adoption/Usage Reporting, Performance Reporting, Post-Launch Revenue/Profi tability Reporting, Trouble-Shooting.

System Specifi cations

The complete AT&T solution comprises a production site and a DR site which function in a parallel, active/active capacity. Each single-site architecture consists of a Processing Cluster, Database Cluster, and Storage Cluster, with the system providing for redundancy at each functional tier.

Processing ClusterThe Processing Cluster provides the capacity to parse, enrich and load records into the database, and makes use of the HP BladeSystem C-Class platform for its application server environment. Mirror parallel nodes at every functional level of the proposed solution provide redundancy and load balancing. The key specifi cations for the Processing Cluster are as follows:• 118 X HP C-Class Blade Servers • 400 X CPU cores (90% at 2.33 GHz and 10% at 2.8 GHz) • Aggregate CPU capacity of approximately 10m TPM• Aggregate Memory capacity of approximately 732 GB

Database ClusterThe Database cluster is based on an HP 9000 Superdome server, split into two partitions running Oracle 10g RAC Enterprise Edition on HPUX 11i.23. The key specifi cations for the Database Cluster is as follows:• 64 X dual-core Itanium Montecito CPUs with

1.6 Ghz/24 MB cache • 4 GB RAM per core • Confi gured into 2 electrically isolated servers • 48 X 1000 Base-T ports • 8 X Ultra 320 SCSI ports• 16 X 146 GB 15K Drives• 16 X 4 GB Fibre Channel HBA ports• 48 X I/O slots

Storage ClusterA Tier1 storage solution is provided through 2 x HP XP-24000 arrays attached to the Processing and Database clusters. This is confi gured as follows:

Other Customers in Brief

Vodafone

Vodafone is a relatively recent LGR customer, but the CDRlive system is already making strong strides within a number of Vodafone group companies. The fi rst installa-tion was with Vodafone Fiji, the smallest Vodafone Group company (500,000 subscribers) and typically the test-bed for new technologies. Key statistics from Vodafone Fiji are as follows:

DB Technology: Oracle 10gR2 RACOperating System: LinuxDB Size: 9 TB Average events loaded per day: 25 millionPeak event load capacity per day: 50 millionHardware vendor: HP

Mcel Mcel is Mozambique’s largest telecommunications network, providing voice and data services to more than 3.5 million subscribers across the country. As a newly privatized organization with a dominant 70% market share, Mcel will be using CDRlive in the coming years to support new opportunities in a country with low mobile penetra-tion, as well as fi ght off competition from new operators entering this fast growing market.

DB Technology: Oracle 10gR2 Operating System: Windows Server 2003DB Size: 4 TBAverage events loaded per day: 38 millionPeak event load capacity per day: 60 millionHardware vendor: HP & NetApp

Mascom

Mascom is Botswana’s largest mobile telecommunica-tions network and in a country of just 1.8 million people, has over half of the total market with more than 1 million subscribers. CDRlive was introduced to Mascom through both companies’ close relationship with the MTN Group, and CDRlive has since delivered competitive advantage to this regional operator for more than 5 years.
