    Abstract: Examples disclosed herein relate to methods and systems for enhancing performance of robust header compression (RoHC) compressor when encountering silence suppression. In one example, an RTP timestamp increment is calculated for successive packets, until a predetermined number of packets have a constant timestamp increment value. The constant RTP timestamp increment value is assigned as a timestamp stride (TS_STRIDE) value for compression, the value of each RTP timestamp (TS) is scaled by timestamp stride (TS_STRIDE) and the header is compressed using the assigned value.

    Abstract: In one embodiment, the present invention comprises a vocoder having at least one input and at least one output, an encoder comprising a filter having at least one input operably connected to the input of the vocoder and at least one output, a decoder comprising a synthesizer having at least one input operably connected to the at least one output of the encoder, and at least one output operably connected to the at least one output of the vocoder, wherein the encoder comprises a memory and the encoder is adapted to execute instructions stored in the memory comprising classifying speech segments and encoding speech segments, and the decoder comprises a memory and the decoder is adapted to execute instructions stored in the memory comprising time-warping a residual speech signal to an expanded or compressed version of the residual speech signal.

    Abstract: métodos e aparelhos para redefinir e transferir de modo seletivo um canal de comunicação sem fio. a presente revelação apresenta métodos e aparelhos para redefinição seletiva de canal. por exemplo, a revelação descreve métodos exemplificadores que podem incluir a determinação que uma célula candidata exibe propriedades superiores de comunicação em uma portadora do que uma célula servidora. em um aspecto, essa portadora pode corresponder a um canal de célula servidora ativa. os métodos exemplificadores também podem incluir a adição de uma sinalização de redefinição a uma mensagem de reconfiguração de canal com base na determinação, em que a sinalização de redefinição instrui um equipamento de usuário a redefinir um subconjunto de um conjunto de canais associado à célula servidora e o subconjunto inclui o canal. ademais, os métodos exemplificadores podem incluir a transmissão da mensagem de reconfiguração de canal, por exemplo, para um equipamento de usuário. dessa forma, um subconjunto especificado de canais associados ao equipamento de usuário pode ser redefinido, o que reduz a carga de sinalização, a complexidade e drenagem de potência associada a métodos e aparelhos de redefinição de canal pré-existentes.
