Packet mode telecommunications method and system in which calls can be handed over from one path to another
First Claim
1. A method of transmitting non-dated or non-numbered digital data in packet mode between a remote transmitter and a remote receiver in which the data is able to take at least two different paths between the transmitter and the receiver and handover from a first path to a second path occurs during transmission, wherein during handover within the transmitter cells or packets intended for the second path are transmitted only after the last cell dr. packet intended for the first path has been transmitted and, wherein during handover within the transmitter and/or within the receiver cells or packets on the first or second path are delayed so that cells or packets on the second path arrive after cells or packets on the first path.

Abstract
The invention concerns a method of transmitting non-dated digital data between a transmitter and a receiver in which the data can take at least two different paths between the transmitter and the receiver and handover from one path to another occurs during transmission. In the transmitter, packets intended for the second path are transmitted only after the last packet intended for the first path has been transmitted and in the transmitter and in the receiver packets on the first or second path are delayed in order for packets on the second path to arrive after packets on the first path. It is therefore not necessary to transmit signaling to differentiate the two paths at the receiver, which can include a single demodulator.
