A text-based information transmission is made complying with a greater number of transport-layer systems by performing the fragmentation and de-fragmentation of the information object at the application-layer side rather than at transport-layer domain. By this manner, the text-based information service is not restricted to transport-layer systems accommodating the maximum size of the information objects. Rather, it is possible to adjust the fragmentation size of the fragments into which the information objects are fragmented to the maximum transport packet content section size offered by the transport layer within the application layer. The fragment size may even vary in a time-varying manner responsive to instructions from the transport layer posed onto the transport layer in consequence of time-varying transmission channel characteristics, for example. |
