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.

Abstract: A method and a system for balancing load between at least two groups of dedicated uplink channels in a telecommunication network serving a plurality of user equipments (18), wherein scheduling requests received from the user equipments (18) and scheduling grants issued to said user equipments (18) are measured. Thereafter, a measurement report based on the measured scheduling requests and the measured scheduling grants is derived, which is forwarded to a radio network unit (10) controlling radio network resources, whereby a re-distribution of available radio resources is made between the at least two groups of dedicated uplinks channels.

Abstract: The present invention comprises a method and apparatus for synchronizing data frames from a wide bandwidth data stream which is divided up and transmitted across a plurality of parallel channels in a mobile telephone system. Prior to transmitting the data frames, a transmit synchronizer synchronizes data frames aligned in the same position in different parallel channels by inserting a common bit from a repeating PN synchronization sequence into the aligned data frames. Upon receiving the data frames at a destination, a receive synchronizer extracts the synchronization bit from each data frame. A series of sequential bits from each parallel channel is compared against the original PN synchronization sequence to identify the position of each data frame relative to the other data frames and reconstructs the original wide bandwidth data stream.
