The 3rd Generation Partnership Project 2 (3GPP2) was a collaboration between telecommunications associations to make a globally applicable third generation mobile phone system specification within the scope of the ITU's IMT-2000 project.
3GPP / TISPAN IMS architectural overview 3GPP / TISPAN IMS architectural overview – HSS in IMS layer (as by standard) Each of the functions in the diagram is explained below. The IP multimedia core network subsystem is a collection of different functions, linked by standardized interfaces, which grouped form one IMS administrative network. [ 7 ]
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 ]
The following parameters are the requirements for IMT-2020 5G candidate radio access technologies. [6] Note that these requirements are not intended to restrict the full range of capabilities or performance that candidate for IMT-2020 might achieve, nor are they intended to describe how the technologies might perform in actual deployments.
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.
It is an acronym for Evolved UMTS Terrestrial Radio Access, [1] also known as the Evolved Universal Terrestrial Radio Access in early drafts of the 3GPP LTE specification. [1] E-UTRAN is the combination of E-UTRA, user equipment (UE), and a Node B (E-UTRAN Node B or Evolved Node B, eNodeB ).
CDMA2000 (also known as C2K or IMT Multi‑Carrier (IMT‑MC)) is a family of 3G [1] mobile technology standards for sending voice, data, and signaling data between mobile phones and cell sites. It is developed by 3GPP2 as a backwards-compatible successor to second-generation cdmaOne (IS-95) set of standards and used especially in North America ...
These two extensions allow users to specify their preferences about the service the IMS provides. With the caller preferences extension, [8] the calling party is able to indicate the kind of user agent they want to reach (e.g. whether it is fixed or mobile, a voicemail or a human, personal or for business, which services it is capable to provide, or which methods it supports) and how to search ...
