Abstract
A transmitting/receiving arrangement, gateway and method for transmitting data over packet network, where a cellular network is connected to a packet network and uplink data frames which carry coded data and certain signaling information related to the coding are transmitted from the cellular network towards the packet network, wherein at least all non-redundant information from the uplink data frames is extracted from the frames and transmitted over the packet network. The gateway connects a packet network to a telephony network.
Claims15
A method for transmitting data over packet network, the method comprising:
- connecting a cellular network to a packet network;
- and
- transmitting uplink tandem free operation data frames, which carry coded data and, in a frame structure, inband tandem free operation signalling information related to the coding, from the cellular network towards the packet network;
- wherein at least all non-redundant information, which comprises said inband tandem free operation signalling information, from the uplink tandem free operation data frames is extracted from said frames to the packet network and transmitted over the packet network, and the coded data from the uplink tandem free operation data frames is extracted and transmitted over a first packet data connection and the tandem free operation signalling information from the uplink tandem free operation data frames is extracted and transmitted over a second packet data connection.

A gateway comprising:
- input block for receiving uplink tandem free operation data frames transmitted from a cellular network towards a packet network, said frames carrying coded data and, in a frame structure, inband tandem free operation signalling information related to the coding;
- extraction block for extracting at least all non-redundant information, which comprises said inband tandem free operation signalling information, from the received uplink tandem free operation data frames;
- and
- output block for transmitting the coded data extracted from the uplink tandem free operation data frames over a first packet data connection and said tandem free operation signalling information extracted from the uplink tandem free operation data frames over a second packet data connection.
