Abstract: A call-setup method in a digital cellular radio communication system determines (12, 14, 16) a plurality of parameters defining the current state of the system. By evaluating and combining (18, 20) these parameters into a communication resource request (22), a communication resource that best matches the request may be allocated (24) in order to optimize system resource usage and/or service quality.

Abstract: A multi-part fixed codebook includes both individual fixed codebooks for each channel and a shared fixed codebook. Although the shared fixed codebook is common to all channels, the channels are associated with individual lags. Furthermore, the individual fixed codebooks are associated with individual gains, and the individual lags are also associated with individual gains. The excitation from each individual fixed codebook is added to the corresponding excitation (a shared codebook vector, but individual lags and gains for each channel) from the shared fixed codebook.

Abstract: A multi-channel linear predictive analysis-by-synthesis signal encoding method determines (S 1 ) a leading channel and encodes the leading channel as an embedded bitstream. Thereafter trailing channels are encoded as a discardable bitstream exploiting cross-correlation to the leading channel.

Abstract: A method and system for measuring the speech quality in a mobile cellular telecommunications network using available radio link parameters is disclosed herein. In a preferred embodiment, the method includes receiving a set of radio link parameters, as defined in a standard or otherwise available, such as the BER, FER, RxLev, handover statistics, soft information, and speech energy. Temporal information is obtained from the radio link parameters to create a set of temporal parameters which can be statistically analyzed, for example, for the maximum and minimum, mean, standard deviation, and autocorrelation values for a time interval. The temporal parameters are combined to yield a set of correlated parameters that are more closely related to the speech quality. An estimator then uses the correlated parameters to calculate an estimate for the speech quality. The method of the present invention takes advantage of temporal information and correlated relationships from the transmitted parameters. Furthermore, the method is inherently simple and reliable as compared to prior art methods. Still further, the technique provides a method and allows operator to monitor quality conditions throughout the network.

Abstract: In a digital cellular radio communication system, a base station selects a speech/channel encoding mode based on measurements of the local radio environment. The mobile station determines the selected mode by trial decoding possible modes to find the most probable mode and uses the same mode for transmission to the base station on the return link. The coding gain/loss obtained by this mode switching may be used to adjust the output power of transmitters, thereby reducing the overall interference level in the system.

Abstract: An analysis-by-synthesis linear predictive speech coder is described. This speech coder has a synthesis part including an adaptive codebook for generating an adaptive excitation, means for generating a multi-pulse excitation and means for generating a transformed binary pulse excitation. The multi-pulse excitation generating means comprises means for generating pulses in restricted pulse positions. The multi-pulse excitation and the transformed binary pulse excitation are combined.
