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.
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 ).
In mobile telephony a bearer service is a link between two points, which is defined by a certain set of characteristics. Whenever user equipment (UE) is being provided with any service (CS/PS service), the service has to be associated with a Radio Bearer specifying the configuration for layer 2 and physical layer in order to have its QoS clearly defined.
The Universal Mobile Telecommunications System (UMTS) is a 3G mobile cellular system for networks based on the GSM standard. [1] UMTS uses wideband code-division multiple access radio access technology to offer greater spectral efficiency and bandwidth to mobile network operators compared to previous 2G systems like GPRS and CSD.

Non-access stratum (NAS) is a functional layer in the NR, LTE, UMTS and GSM wireless telecom protocol stacks between the core network and user equipment. [1] This layer is used to manage the establishment of communication sessions and for maintaining continuous communications with the user equipment as it moves.

GSM-R is a TDMA ("Time-Division Multiple Access") system. Data transmission is made of periodical TDMA frames (with a period of 4.615 ms), for each carrier frequency (physical channel). Each TDMA frame is divided in 8 time slots, named logical channels (577 μs long, each time-slot), carrying 148 bits of information.
Route Reestablishment Notification (RRN) is a type of notification that is used in some communications protocols that use time-division multiplexing This article related to telecommunications is a stub .
