CASE STUDY FOR TELECOMMUNICATIONS

3. + Overview
Altibase
Altibase is provider of In-Memory
Database solutions for real-time
access, analysis and distribution of
high volumes of data in mission-
critical environments.
China Unicom
China Unicom, through its subsidiary,
Jiangsu Unicom, serves millions of
prepaid mobile customers in the
Jiangsu Province, China.
Summary
Altibase enabled China Unicom’s customers to check remaining balances
which increased customer satisfaction and maximized retention.
In-Memory Database Solution

4. + Problems
Historically, China Unicom suffered from payment defaults and
operational deficiencies manifesting themselves in three core areas.
 Inability to Effectively Terminate Service: China Unicom was unable to
identify and cut customer usage when prepaid balances were exhausted.
Essentially, customers who chose to game the system, would talk for free
until China Unicom’s systems “caught up.” China Unicom’s DBMS could not
efficiently detect negative balances. Worse yet, losses shadowed increasing
latency. The result was uncollectible receivables.
 Inability to Reinstate Timely Service: Unfortunately, customers who
inadvertently exhausted their balances and subsequently paid their
overages, suffered also. Limitations in China Unicom’s DBMS speed
prevented swift reactivation of service to these loyal customers. The result
was a catastrophic loss of consumer confidence, customer satisfaction and
ultimately, retention.
 Inability for Customers to Accurately Check Remaining Balances: Since
customers could not accurately check their current balances, they could not
preemptively replenish their accounts. The balance information was stale
and loyal customers paid the price with defunct service.
In-Memory Database Solution

5. + Solution
ALTIBASE HDB In-Memory DBMS1 provided China Unicom with
performance, reliability and functionality all with the
underpinnings of a complete solution. Fortifying China Unicom’s
decision to utilize ALTIBASE HDB was Altibase’s stellar reputation
for excellent technical support2.
In-Memory Database Solution
1) China Unicom installed Altibase HDB as an in-memory only
database on an IBM P6-570 system with 16 * 4.7 GHz power6
CPUs and 156GB of memory.
2) Only two weeks of development effort was required to
implement a DBMS query wrapper interface based on Altibase's
standards-compliant ODBC interface.

6. + Results
 China Unicom has the capacity to precisely check and act on customer
balances.
 Customers cannot take advantage of China Unicom’s system latencies.
 Outstanding balances, when paid, coincide with swift restoration of
service.
 Customers can check accurate remaining balances, knowing when to
reload funds.
 Customer satisfaction, loyalty, attraction and retention are maximized.
 Customer attrition is minimized.
 Losses attributable to undetectable “free usage” as well as payment
deficiencies are mitigated.
