For networks using "store and forward" functionality of short data messages (sent on signaling channels), no mechanism is currently defined in the existing GSM, TETRA or other applicable standards to enable an originating short data entity to cease waiting for delivery reports. Depending on the means of determining datagram uniqueness, this may degrade or cause congestion in the operation of packet-based or other short data applications in the originator of the short data datagram(s). After some analysis, it has been concluded that there are two key issues facing store and forward networks that are not addressed by the standards: (1) there is no defined mechanism for returning delivery reports from a store and forward entity to an originating MS; and, (2) there is no mechanism for the originating MS to know to cease waiting for a delivery report. For wireless networks supporting store and forward functionality (such as an SMSC in a GSM network) for short data transmission, this invention describes a mechanism for delivery retries and expiring delivery reports returned to an originating entity.
