RTWP

Its Received Total Wideband Power.
the total level of noise within the UMTS frequency band of any cell.
RTWP is related to uplink interference.
Because of Uplink Interference you faced call drop.
Actually its indication of Uplink Interference in Cellular Network.

General value is nearly -104 or -105 dBm.

LAI

LAI:Location Area Identity

The Location Area Identity (LAI) uniquely identifies a Location Area (LA) within a mobile network. It consists of the Mobile Country Code (MCC), the Mobile Network Code (MNC) and the Location Area Code (LAC).

The LAI is used to keep track of the mobile subscribers in the network. This record is kept in a database such as the Visitor Location Register (VLR) in the GSM network.

LAC

The served area of a cellular radio network is usually divided into location areas. Location areas are comprised of one or several radio cells. Each location area is given an unique number within the network, the Location Area Code (LAC).

This code is necessary to address the subscriber in the case of an incoming call.

LAC information sent on BCCH.

When Subscriber changes LAC than it update about new LAC to VLR through SDCCH.

BCCH

BCCH:Broadcast Control CHannel.
Its logical brodcast channel used in GSM network to send identity of network.This information is used by a mobile station to get access to the network.
The Information include MCC,MNC,LAC and all togather CGI.

UMTS

Universal Mobile Telecommunications System (UMTS) is one of the third-generation (3G) mobile telecommunicationstechnologies.The first deployment of the UMTS is the release99 (R99) architecture. It is specified by 3GPP and is part of the global ITU IMT-2000 standard.

UMTS is one of Emerging Technology used in communication.

Video call and High Data Rates is a key Feature for UMTS.

UMTS went live as a network for the first time in Japan in 2001. Austria had its own network two years later. A handful of other European countries joined the UMTS bandwagon in the next two years, with South Africa and a few other African countries soon following suit. The U.S. has employed UMTS networks in several large cities, and the number is steadily growing.

UMTS have Different Releases for more Advanced Technology.
