Abstract:
A method for transmitting GSM data between at least two stations over a communication network, the method comprising the steps of:checking whether the data to be transmitted from a transmitting station are present in a predefined frame format;if the data is in the predefined frame format, performing the following:checking whether a coding rate of the transmitting station is identical to a coding rate of a receiving station;switching the data through transparently and preserving the predefined frame format if the coding rate of the transmitting station is identical to the coding rate of the receiving station;recoding the data to another coding rate and preserving the predefined frame format if the coding rate of the transmitting station and the coding rate of the receiving station are different;wherein, when the coding rate of the transmitting station and the coding rate of the receiving station are different, decoding is first performed for a compression used on a transmitting side and then encoding is performed for a compression used on a receiving side; andwherein recoding is performed only on a segment between the communication network and the receiving station.
