MEDIA OFFLOAD FOR MOBILE COMMUNICATIONS APPLICATIONS

摘要

Various technologies described herein pertain to operating a multi-processor mobile device. An application client executing on an application processor of the multi-processor mobile device negotiates a media session with a service. Responsive to the media session being negotiated, a media offload request is signaled from the application processor to a baseband processor of the multi-processor mobile device. The media offload request includes identification information that signifies packets that form part of the media session. Responsive to receipt of the media offload request, incoming packets received by the baseband processor from a base station are evaluated to detect whether the incoming packets form part of the media session. The incoming packets that form part of the media session are redirected from the baseband processor to a digital signal processor without being routed through the application processor and processed to generate an output, where the output is transmitted to an output device.

1. A method of operating a multi-processor mobile device, comprising:
negotiating a media session with a service, wherein an application client executing on an application processor of the multi-processor mobile device negotiates the media session with the service; responsive to the media session being negotiated by the application client, signaling a media offload request from the application processor to a baseband processor of the multi-processor mobile device, wherein the media offload request comprises identification information that signifies packets that form part of the media session; responsive to receipt of the media offload request, detecting whether incoming packets received by the baseband processor from a base station form part of the media session based upon the identification information; redirecting the incoming packets that form part of the media session from the baseband processor to a digital signal processor of the multi-processor mobile device without being routed through the application processor; processing redirected packets on the digital signal processor to generate an output; and transmitting the output to an output device.
