Abstract
A method for performing encoding in a cellular network includes, in each cell, at least one base station communicating with terminal equipment within its coverage area, and a mobile switching center controlling the operation of the base stations. In order to improve the transmission quality over a connection between two terminal equipment, when the mobile switching center detects, during call set-up or handover, that the call is between two terminal equipment located within the area of the mobile switching center, the mobile switching center guides the transcoders of base stations communicating with the terminal equipment to a mode in which the transcoders adapt the rate to fit the transmission network, but do not encode the speech signal.
