Indian mobile operator IDEA Cellular has chosen Nokia Siemens Networks to upgrade its network in 22 telecom service areas. NSN will add GPRS capability to ten of IDEA’s service areas and expand it in 12 others. The services will be enabled by NSN’s GPRS technology and Unified Charging Solution (UCS evolve) by March 2010. The latter will give IDEA a single, real-time charging system for the new services for prepaid and postpaid subscribers across all the areas.
