Abstract: A location management method for a mobile terminal in a telecommunications network is provided in which when the mobile terminal is traveling from a first cell to a second cell in the network, an identifier associated with the mobile terminal in the cell in which it is located is established. The mobile terminal receives a first identifier associated with the first cell that enables the mobile terminal to be located in the network when it is within the first cell. The mobile terminal receives a second identifier associated with the second cell that enables the mobile terminal to be located in the network when it is within the second cell. The mobile terminal and/or the network store the identifiers in a table of identifiers, in order to use the first identifier or the second identifier depending on whether the mobile terminal is within the first or second cell, respectively.

Abstract: A method for backing up and re-transmitting voice messages being transmitted during a call from a mobile device to an answering machine with a dedicated address in a network includes measuring the transmission quality between the mobile device and the answering machine while a connection is established between the mobile device and the answering machine, recording the voice message in the mobile device while it is being transmitted to the answering machine, after the call has ended and the mobile device has disconnected from the network, creating a data message in the mobile device containing the recorded voice message and the address of the called device, setting up a connection from the mobile device to the network, and sending the data message.
