Abstract: The present invention is a method for improving data transfer performance over communications networks connecting data networks and users using adaptive communications formatting. Adaptive communications formatting includes encoding (or compressing) the data and applying error control schemes to reduce the amount of data being transmitted and to correct and/or conceal errors occurring during data tra nsmission. In one embodiment, the present invention uses a set of transcoding techniques to encode (or compress) the data and a set of error control schemes to correct and/or conc eal errors occurring during data transmission. The particular sets of transcoding technique s and error control schemes selected to format the data are adaptive to factors, such as the nature of the communications network connecting a user to an access server on th e data network, the preferences of the user, and the data type of the data being transm itted to the user (or the access server).

Abstract: Automatic Speech Recognition (ASR) is achieved in wireless communications systems in which reliable ASR feature vector sequences are derived at a base station directly from digitally transmitted speech coder parameters, with no additional processing or signal modification required at the originating handset. No secondary channel need be provided for the transmission of ASR feature vectors. In operating on received speech coder parameters prior to conversion to a voice signal the present system and methods avoid the lossy conversion process and associated voice distortion. Since the received voice parameters are error protected during transmission they are received with greater accuracy.

Abstract: Non-speech information is sent in the bits allocated to one or both of a vocoder's codebooks' output by selling the gain for the corresponding codebook to zero. By selling the gain to zero, the codebook output will not be interpreted by the receiving vocoder. In this way, it is possible to transmit additional information in a way that is totally transparent to the vocoder. Applications for this technique of sending "secret" messages include, but is not limited to, transmitting parameters for generating non-speech signals. As an example, information to generate call waiting tones, DTMF, or TTY/TDD characters can be clandestinely embedded in the compressed bit stream so that these non-speech tones can be regenerated.

Abstract: In one example embodiment of the present invention, a method of managing information at a base station in a wireless network includes determining whether first information is at least one of low priority information and high priority information. The method further includes queuing the information if the information is determined to be low priority information, and sending the information to a mobile station if the information is determined to be high priority information.
