The Radio Resource Control (RRC) protocol is used in UMTS, LTE and 5G on the Air interface. It is a layer 3 (Network Layer) protocol used between UE and Base Station. This protocol is specified by 3GPP in TS 25.331 [2] for UMTS, in TS 36.331 [3] for LTE and in TS 38.331 [4] for 5G New Radio. RRC messages are transported via the PDCP-Protocol.
In telecommunication, a public land mobile network (PLMN) is a combination of wireless communication services offered by a specific operator in a specific country. [1] [2] A PLMN typically consists of several cellular technologies like GSM/2G, UMTS/3G, LTE/4G, NR/5G, offered by a single operator within a given country, often referred to as a cellular network.
Mobile phones use geographic area codes. Exchanges may service on mobile devices; local numbers are portable between wired and wireless carriers. While area code 600 has been established as a non-geographic code that can be used by mobile phones, the only significant mobile usage has been for satellite phone service in remote regions. Cape ...

A wireless telephone base station communicates with a mobile or hand-held phone. For example, in a wireless telephone system, the signals from one or more mobile telephones in an area are received at a nearby base station, which then connects the call to the land-line network. Other equipment is involved depending on the system architecture.

In modern communications systems, such as cellular (mobile) networks, the call setup procedure maybe very complex and the point at which a call is considered successfully connected may be defined in a number of ways, thus influencing the way the call setup success rate is calculated. If a call is connected successfully but the dialled number is ...
E-UTRA is the air interface of 3rd Generation Partnership Project Long Term Evolution (LTE) upgrade path for mobile networks. 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 ]
