Since SG-SMS messages are carried over the downlink NAS is it possible that a flood of SMS messages from the SMSC can deny services to users in the affected cells? The use case is associated with location-based SMS.
If a large number of SMS messages are sent to a targeted group of users within a cell is it possible that the NAS cannot serve requests to establish connections from the UEs? Is it possible to prioritize the information carried over the NAS or, failing that, to randomize the selection of which messages are sent so that SMS does not prevent other service requests from being processed?
