AI Technical Summary

Problems solved by technology

This data throughput gap (gap) in the handover scenario from Wi-Fi to cellular can lead to a degradation in user experience during the period when the data stream is given to cellular until it can compensate for the encoding rate adaptation on the application layer (audio and / or or the video is stalled or disappears completely)

Embodiment Construction

[0020] The following detailed description refers to the accompanying drawings, which show, by way of illustration, certain details and aspects of the disclosure. The word "exemplary" is used herein in the sense of "serving as an example, instance, or illustration." Any aspect of the disclosure or designs described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other aspects of the disclosure or designs.

[0021] figure 1 is an illustration of a wireless network according to aspects of the disclosure. In aspects of the present disclosure, wireless network 2 may be a network implemented with radio signals. In various aspects, the various components of wireless network 2 may use wired connections as well as wireless connections. The wireless network 2 may be a wireless wide area network (WWAN). WWAN can use mobile telecommunications cellular network technologies such as Long Term Evolution (LTE), LTE-Advanced, WiMAX (commonly known ...

Abstract

The present invention relates to methods and apparatus for rate adaptation for quality of service based applications. A method, system and computer program product for identifying network congestion in a communication system. A connection manager identifies a plurality of packet delay times for a plurality of data packets within the communication system; determines whether at least one packet delay time satisfies a threshold; and adjusts a congestion indicator in response to the at least one packet delay time satisfies the threshold.

Description

technical field [0001] Aspects of the disclosure generally relate to rate adaptation. In particular, aspects of the present disclosure relate to identifying network congestion in a communication system. Background technique [0002] User Equipment (UE) such as smartphones, tablets, laptops, etc. are increasingly equipped with both WLAN (eg Wi-Fi) and 3G (UMTS, LTE) cellular radio (WWAN). A multi-radio UE can connect to the Internet over WLAN whenever it is available, and switch to WWAN when it detects performance degradation on WLAN or WLAN is not beneficial for other reasons. [0003] Peak and average data rates and round trip latency times in the uplink and downlink can vary significantly and / or fluctuate when both wireless technologies are used together. In a handover scenario from Wi-Fi to cellular, a typical Wi-Fi connection such as 802.11g offers theoretically up to 54Mbps over the air compared to the typical 3G Rel-7 / Cat-14 data rate of 21Mbps peak data rate. In f...
