Abstract (en)

[origin: WO2005104582A1] The invention relates to a method and device for establishing a TrFO connection between two communication terminals through a communication network. According to said invention, at least one codec mode configuration, supported by a radio network controller (RNC1, RNC2), involved in a connection establishment, is stored into a memory unit (T1, T2). This information is transmitted between the switching units (MSC1, MSC2) and used for selecting a codec mode configuration, or a subset of a codec mode configuration, supported on both sides.
