Abstract
A method and apparatus for accessing information in a wireless network is provided by determining whether a wireless connection from a mobile platform to a server is a phone call or a telematics call, selecting one of a phone call filter and a telematics filter based on the wireless connection determination, and filtering a voice signal for the wireless connection with the selected filter. The method and apparatus provides techniques for adapting a noise cancellation ratio to different types of wireless connections, including a hands-free phone mode and a telematics mode.
