Abstract: A method for adaptive audio codec selection during a communication session is disclosed. The method can include negotiating a set of audio codecs for use during the communication session. The method can further include defining multiple audio tiers. Each audio tier can be associated with a network condition and can define an audio codec from the set of audio codecs for use in the associated network condition. The method can also include using a first audio codec during the wireless communication session. The method can additionally include determining a changed network condition selecting a second audio codec by determining the audio tier corresponding to the changed network condition. The method can further include, in response to the changed network condition, switching from the first audio codec to a second audio codec that is defined by an audio tier having an associated network condition corresponding to the changed network condition.

Abstract: A wireless device described herein can use information on data flow, in addition to indications from the physical network, to decide on suitable bandwidth usage for audio and video information. This data flow information is further used to determine an efficient network route to use for high-quality reception and transmission of audio and video data, as well as the appropriate time to switch between available network routes to improve bandwidth performance.
