Abstract
Improved techniques for providing reference numbers for purposes of fragmenting a message for transmission over a network (e.g., a wireless data network) that supports only a limited size message are disclosed. The reference numbers for the fragmented messages are shared by groups of destinations (e.g., subscribers or mobile devices). As a result, the number of reference numbers to be stored is small compared to the number of possible destinations, and the size of the reference numbers themselves is also kept small. The number of groupings and the size of the reference numbers can also be adjusted to fit system objectives.
