Patent KR-20020095181-A (KR)
IPC: H04L1/16
Filed: 2001-01-11
Abstract: A modified unacknowledge mode of a telecommunications system interface is defined by providing for a special signaling indication by way of a selected packet, signaling sequence, message, or the like, from a transmitting side to a receiving side that a given message, packet, cell, signaling sequence, or the like is to be treated specially, despite the unacknowledge mode being used, by acknowledging receipt thereof at the receiving side back to the transmitting side. In this way, certain important messages can be acknowledged, while less important messages can be sent without acknowledgement. This reduces the need for wasteful use of capacity for applications in which some of the messages are more important than others to be received correctly.
