The Universal Mobile Telecommunications System (UMTS) is a 3G mobile cellular system for networks based on the GSM standard. Developed and maintained by the 3GPP (3rd Generation Partnership Project), UMTS is a component of the International Telecommunication Union IMT-2000 standard set and compares with the CDMA2000 standard set for networks based on the competing cdmaOne technology.
UMTS Terrestrial Radio Access Network (UTRAN) is a collective term for the network and equipment that connects mobile handsets to the public telephone network or the Internet. It contains the base stations, which are called Node B 's and Radio Network Controllers (RNCs) [ 1 ] which make up the Universal Mobile Telecommunications System (UMTS ...
The 3rd Generation Partnership Project (3GPP) is an umbrella term for a number of standards organizations which develop protocols for mobile telecommunications. Its best known work is the development and maintenance of: [1] GSM and related 2G and 2.5G standards, including GPRS and EDGE; UMTS and related 3G standards, including HSPA and HSPA+
The phone system weighed 11 kg (24 lb). It was placed in the trunk of the vehicles of high-ranking officials and used a standard handset in the passenger compartment. The main developers of the Altai system were VNIIS (Voronezh Science Research Institute of Communications) and GSPI (State Specialized Project Institute).

This category is for articles describing features unique to only UMTS networks. If the article is describing a feature implemented in more than one type of 3GPP network and defined by 3GPP, put it in Category:3GPP standards. An example of this is a feature implemented in both GSM and UMTS networks, or a feature that interfaces GSM and UMTS ...
A definition for CCPCH in UMTS can be found in 3GPP 25.211 Physical channels and mapping of transport channels onto physical channels (FDD) and 25.221 Physical channels and mapping of transport channels onto physical channels (TDD) (These are not easy to read documents as they are intended for an audience with substantial and detailed knowledge of the subject.
