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 code-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.
