Question: In a multi-technology network of one operator, how should values identifying a given topic be handled for both Message ID and Message Identifier across different technologies?
Option 1: Unique values for each technology type (GSM, UMTS, etc.) to differentiate between them.
Option 2: Identical values within the same operator's network but unique across different operators.
Option 3: Values determined by the UE's capabilities and stored in the 'list of CBS messages to be received'.
Option 4: Identical values for both Message ID and Message Identifier, regardless of the technology (GSM, UMTS, etc.), within one operator's network.
Explanation: To ensure seamless service delivery across different technologies within a single operator's network, consistency in message identification is crucial. Thus, having identical values for both Message ID and Message Identifier ensures the UE can appropriately handle CBS messages regardless of the technology being used, simplifying message management and reception logic within the UE.
