3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
CBS message: An information message broadcasted on the basic or extended cell broadcast channel (CBCH) in
unacknowledged mode to mobile stations located within the Cell Broadcast area. A CBS message may contain
information such as road traffic or weather information, originating from a Cell Broadcast Entity (CBE) communicating
with the CBC (see 3GPP TS 23.041 [1]).

3GPP TS 48.049 version 13.0.0 Release 13 8 ETSI TS 148 049 V13.0.0 (2016-01)
CBS message reference: Uniquely identifies a CBS message by the four elements: Message Identifier, Serial Number,
Cell Identifier and Channel Indicator.
Cell Broadcast area: An area comprising of one or more cells in which the CBS message or the emergency message is
broadcasted. A Cell Broadcast area is always contained within a BSC area (see 3GPP TS 23.002 [14]).
CBS message operational state: A cell in CBS message operational state is able to broadcast CBS messages.
Emergency message: A warning message conveying a small amount of data to indicate the imminent occurrence of an
emergency such as earthquake, tsunami etc. The emergency message is broadcasted to mobile stations in idle mode,
packet idle mode and dedicated mode (see 3GPP TS 44.018 [12]) and to mobile stations in packet transfer mode and
dual transfer mode (see 3GPP TS 44.060 [13]) located within the Cell Broadcast area.
Emergency message operational state: A cell in emergency message operational state is able to broadcast emergency
messages.
Emergency message reference: Uniquely identifies an emergency message by the three elements: Message Identifier,
Serial Number and Cell Identifier.
Elementary Procedure: CBSP consists of Elementary Procedures (EPs). An Elementary Procedure is a unit of
interactions between the CBC and the BSC. These EPs are defined separately and are intended to be used to build up
complete sequences in a flexible manner. If the independence between some EPs is restricted, it is described under the
relevant EP description. Unless otherwise stated by the restrictions, the EPs may be i
