Description:RELATED APPLICATION
[0001] This patent application is related to India Patent Application No. 201747018111, filed on 23 May 2017, entitled “ LINK-AWARE STREAMING ADAPTATION”.

BACKGROUND
[0001] The growth of multimedia services, including streaming and conversational services, is one of the key drivers of the evolution to new mobile broadband technologies and standards. Digital video content is increasingly consumed in mobile devices. There are many video applications extensively used on mobile devices in daily life. For example, online video streaming include popular services such as YouTube and Hulu. Video recording and video conferencing include services such as Skype and Google Hangout. In 2013, YouTube had more than 1 billion mobile video views per day. As more smart phones, tablets, and other mobile computing devices are purchased, their use for video recording and video conferencing will increase dramatically. With such high consumer demand for multimedia services coupled with developments in media compression and wireless network infrastructures, it is of interest to enhance the multimedia service capabilities of future cellular and mobile broadband systems and deliver high quality of experience (QoE) to the consumers, thereby ensuring ubiquitous access to video content and services from any location, at any time, with any device and technology.

, Claims:1. A method to be performed at multimedia telephony services over internet protocol multimedia subsystems (MTSI)-based User Equipment (UE) to provide wireless communication of multimedia content in a cellular network, the method comprising:
processing a communication from a RAN node, the communication including information to identify a first bit rate corresponding to a suggested bit rate to communicate a video frame in the cellular network;
determining an average physical layer goodput of the MTSI-based UE corresponding to video frame communication, the physical layer goodput equal to a sum of physical layer goodputs of bits of received video frames over a predetermined time window;
performing a video rate adaptation algorithm to determine a second bit rate corresponding to a bit rate to be used to communicate the video frame, the video rate adaptation algorithm based on the average physical layer goodput, the first bit rate, and further on higher layer parameters corresponding to video communication by the MTSI-based UE;
determining the second bit rate from the video adaptation algorithm; and
sending the video frame for transfer from the MTSI-based UE at the second bit rate and subject to a delay constraint.
