摘要：
This invention pertains to methods and apparatus for data communications from vehicles, to obtain emergencies, concierge and other services, using a voice channel of a digital wireless telecommunications network. Signaling is described (FIG. 3) between a Server and an InΑ/βhicie System (FIG. 2) for commencing data sessions after establishing a voice channel call. Responsive to a predetermined signaling tone, a switch (PCM) mutes the speaker of the in-vehicie audio system. The call may be initiated from the vehicle automatically, and the call taker location may be unattended. Signaling methods are selected (FIGS. 4-5) for traversing both newer and legacy vocoders for ubiquitous operation.
