The SICAP architecture
An offer from Swisscom for GSM network operators, service
providers and service operators.
The basis for SICAP is a
client server architecture with extended universal SIM-Card as client and the SICAP Service
Centre (SSC) as server. Short Message Services (SMS), with their outstanding properties,
serve as the communication medium. The capabilities of the SIM-Card have so far been used
only to a limited extent. The system enables executable programs to be transmitted to the
SIM-Card. Pre-Paid Billing (PPB) manages prepaid customers and their credits, handles
recharge orders and supervises their execution. Validation (VAL) supports validation and
recharging of SIM-Cards. Over the Air (OTA) genrates and controls SICAP Short Message
Services between the network and the mobile phone. Interactive Voice Response (IVR) is a
computer-aided voice response system. It supports the recharging of SIM-Cards via value
card.
AkadiaAG
is working on the new SICAP database design which will offer many new GSM - and Value Added
Services to the subscribers. The existing Oracle-7 Databases VAL, OTA and PPB will be
merged to one single database based on Oracle-8. One of the greatest benefits for the
migration is the Partitioning Option of Oracle-8 to split very large tables in vertical,
manageable slices.
