Interop enhances CDMA2000 OTA provisioning solution

CTIA WIRELESS 2011, FORT MYERS, USA: Interop Technologies, a provider of core wireless solutions for messaging, device management, and connectivity gateways, has broadened its powerful CDMA OTA provisioning solution to manage Removable User Identity Module (R-UIM) cards for CDMA2000 handsets.

This new capability enables network operators to access elementary files on R-UIM cards to update Preferred Roaming Lists (PRLs), service programming codes, and text messaging services directly on the R-UIM cards of subscriber handsets.

Elementary files are also utilized to update devices on Long Term Evolution (LTE) networks. LTE utilizes Universal Integrated Circuit Cards (UICCs), which are controlled by a CDMA Subscriber Identity Module (CSIM) that relies on elementary files for device updates. Interop’s ability to access elementary files to update R-UIM cards means the company is well-positioned to extend its CDMA OTA provisioning solution to LTE operators in the near future.

Working with the CDMA Development Group (CDG) to help define standards for CDMA Open Market Handsets (OMH), Interop Technologies has expanded the capabilities of its CDMA OTA provisioning solution to utilize Over-the-Air Service Provisioning (OTASP). OTASP enables subscribers to quickly and easily activate R-UIM and OMH SIM cards.

Furthermore, the Interop CDMA OTA solution offers an optional Interactive Voice Response (IVR) system fully integrated into the Over-the-Air Function (OTAF). The IVR saves operators time and resources by automating routine tasks while making support services available around the clock.

With Over-the-Air Parameter Administration (OTAPA), operators can send mass updates to subscriber R-UIM cards or reprogram individual cards, supporting the introduction of new services. The technology enables customer service representatives to perform “one-off” updates, giving engineers time to focus on higher level technical tasks.

Interop’s CDMA OTA solution provides full business visibility with real-time, Web-based customer care and reporting from the OTA campaign to the individual customer level. Additionally, Interop’s CDMA OTA solution enables an operator’s network to update and modify A-Key provisioning data, adding an extra measure of security for subscribers.

In addition to OTASP and OTAPA support for R-UIM, the Interop CDMA OTA solution supports ESN, MEID, pESN, and EUMID equipment identification numbers. The solution also offers a configurable SPC algorithm and retry mechanism providing high activation accuracy with “five nines” (99.999 percent) reliability.
