Device and method for managing communications between data communications systems

摘要

The device (100) includes a processor (132) coupled to a memory (134) containing a program adapted to control the processor (132) to manage communications between data communications systems. The management method includes the steps of receiving a first message sent from a first data communications system (102) comprising a plurality of blocks (202), determining whether the blocks (202) of the first message are transferable or non-transferrable, sending a request repeat message to the first data communications system (102) to request the first data communications system (102) to resend the non-transferable blocks (202) of the first message if the processor (132) determines that any of the blocks (202) of the first message are non-transferable, and sending the transferable blocks (202) in the form of a second message comprising a first plurality of fragments (206) to a second data communications system (106) without waiting for the first data communications system (102) to resend the non-transferable blocks (202).
