Method and device for transmitting ip packets between a radio network controller (rnc) and another element of a mobile radio network
First Claim
1. A method for transmitting IP packets between a Radio Network Controller and another element in a mobile radio network, comprising:
- transmitting an IP packet that includes a first coder-decoder mode indication, which indicates the coder-decoder mode with which it was transmitted from a mobile terminal to a first Radio Network Controller;
a coder-decoder indication exchange system passed through by an IP packet via the mobile radio network, exchanging the first coder-decoder mode indication included in the data packet for a second coder-decoder mode indication corresponding to the first coder-decoder mode indication according to a stored table in the coder-decoder mode indication exchange system and known to the another element or mobile terminal; and
forwarding the IP packet, which includes the second coder-decoder mode indication, the another element.

Abstract
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.
