ABSTRACT:
Saving bandwidth on the Abis interface in mobile communication systems. When congestion appears on an Abis full rate channel communication is switched over to half rate while keeping full rate on the radio interface. Thereby possibilities are still available for good error correction and control on a highly interfered radio channel.
