Radio power saving techniques for video conference applications

摘要

In video conferencing over a radio network, the radio equipment is a major power consumer especially in cellular networks such as LTE. In order to reduce the radio power consumption in video conferencing, it is important to introduce an enough radio inactive time. Several types of data buffering and bundling can be employed within a reasonable range of latency that doesn't significantly disrupt the real-time nature of video conferencing. In addition, the data transmission can be synchronized to the data reception in a controlled manner, which can result in an even longer radio inactive time and thus take advantage of radio power saving modes such as LTE C-DRX.

主权项

1. A method for handling conference data, comprising:
by a first user equipment (UE), performing operations for:
receiving real-time conference data to be transmitted to a second UE or a basestation over a wireless network as part of a real-time conference session;buffering the real-time conference data for a delay time period;generating a conference data bundle that comprises synchronized audio and video data from the real-time conference data; andtransmitting the conference data bundle to the second UE or the basestation over the wireless network after the delay time period.
