METHOD AND DEVICE FOR TRANSMITTING IP PACKETS BETWEEN A RADIO NETWORK CONTROLLER (RNC) AND ANOTHER ELEMENT OF A MOBILE RADIO NETWORK

摘要

The invention relates to a method for transmitting IP packets between a radio network controller (RNC) (2) and another element of a mobile radio network. Said method is characterised in that an IP packet to be transmitted contains a first coder-decoder mode indication (TFCI, AMR) which indicates the coder-decoder mode (TFCI, AMR) used to transmit the IP packet from a mobile terminal (MT) (1) to a first radio network controller (RNC) (2); a coder-decoder mode indication exchange system (DCF) (5) through which an IP packet passes on the way through the mobile radio network exchanges the first coder-decoder mode indication (RFCI, AMR) contained in the data packet, with a second coder-decoder mode indication (RFCI requested) which is known to another element or mobile terminal (MT) (1) and corresponds to the first coder-decoder mode indication according to a table stored in the coder-decoder mode indication exchange system (5); and the IP packet containing the second coder-decoder mode indication is sent on to other elements.
