name: RRC
full_form: Radio Resource Control
context: broadcast of typically cell-specific information. - Establishment, re-establishment, maintenance and release of an RRC connection between the UE and UTRAN. The establishment of an RRC connection is initiated by a request from higher layers at the UE side to establish the first Signalling Connection for the UE. The establishment of an RRC connection includes an optional cell re-selection, an admission control, and a layer 2 signalling link establishment. The release of an RRC connection can be initiated by a request from higher layers to release the last Signalling Connection for the UE or by the RRC layer itself in case of RRC connection failure. In case of connection loss, the UE requests re-establishment of the RRC connection. In case of RRC connection failure, RRC releases resources associated with the RRC connection. - Establishment, reconfiguration and release of Radio Bearers. The RRC layer can, on request from higher layers, perform the establishment, reconfiguration and
description: Radio Resource Control (RRC) is a protocol responsible for managing radio resources between the User Equipment (UE) and the Universal Terrestrial Radio Access Network (UTRAN). It handles functions such as broadcast of cell-specific information, establishment and release of RRC connections, and management of Radio Bearers. The RRC protocol plays a crucial role in controlling the flow of data between the UE and the network.
explanation: The context describes RRC's functions like connection management, radio bearer control, and cell-specific information broadcasting, all of which are typical duties of a communication protocol.
