10.2.30 RADIO BEARER RELEASE

25.3313GPPProtocol specificationRadio Resource Control (RRC)Release 17TS

This message is used by UTRAN to release a radio bearer. It can also include modifications to the configurations of transport channels and/or physical channels. It can simultaneously indicate release of a signalling connection when UE is connected to more than one CN domain.

Explanation

FACH_PCH

This IE is mandatory default when a transition from CELL_DCH to CELL_FACH, URA_PCH or CELL_PCH is requested by the message and is not needed otherwise.

Non-rectangularResourceAllocation

This IE is optionally present if non-rectangular resource allocation is configured. Otherwise, it is not needed.
