For example: A Message Identifier value is compared to the value 4370 and to 4383 (shown inside the box) in ord

Message Identifier value in CBS = 4370 or 4383?Even though the flow chart uses the term CBS, the flow chart is applicable to GSM, UMTS, and E-UTRAN access technologies. In GSM and UMTS, the CMAS messages are broadcast by the CMSP network using the Cell Broadcast Service capabilities. In E-UTRAN, the CMAS messages are broadcast by the CMSP network using Pubic Warning System capabilities.
