Problems solved by technology

Note that after some RR messages are received, an end-to-end reaction by the ISP may occur, which may take tens of seconds, and it will be calculated based on RTP packet loss and jitter only, as a result, the ISP reaction tends to vary too slow and delayed to offset the insufficient bandwidth

Embodiment Construction

[0088]Figure 4 shows a 3GPP multi-RAT PLMN, the operation of which has been modified to embody the invention which will be described. The PLMN consists of a core network (CN) connected to two different access networks, the well-integrated GERAN, and the recently introduced UTRAN. The latter improves data services due to its greater throughput and ability to route asymmetric IP data traffic flows. The two access networks share the same GPRS service, as does the pre-existing GSM core network. Both UTRAN and GERAN are wirelessly connected to a plurality of mobile terminals of UE / MS type, each of which comprises a mobile equipment ME with a corresponding USIM card. The present invention is applicable to single-standard MS / UE terminals, but is preferably applicable to multi-standard MS / UE terminals. The UTRAN comprises a number of Node B blocks, each connected to a respective Radio Network Controller RNC via an Iub interface. A Node B comprises a Base Transceiver Station BTS, wh...

Abstract

An end to end fast signalling procedure is disclosed in order to improve standard RTP / RTCP transport protocols for the support of streaming services with in any kind of wireless and / or mobile networks, in particular for the introduction within GSM-GPRS. The streaming flow is expected to be sent from an Internet Service Provider (ISP) to Mobile Stations (MS). During fast signalling procedure, RTCP feedback messages are sent at a rate higher then the one expected in standard RTCP protocol. Fast signalling messages are made by upgraded Receiver Reports (FRR) intended to make the end to end QoS control mechanism able to react quickly to sudden changes in the available bandwidth that can occur at the radio interface.

Description

technical field [0001] The invention relates to the field of unicast and multicast of audio-video streaming services in wireless networks having the features set forth in the preamble of claim 1 and, more particularly, to the field of The process of introducing fast end-to-end transport layer signaling during streaming services. Possible candidate networks are, for example: mobile radio networks of the 2.5G, 3G, B3G, 4G generations, WLAN, and PMP networks with a master station and fixed slave stations. A common constraint of those networks is that sudden changes in available bandwidth may occur on the radio interface. Multimedia streaming services are delivered through Internet service providers or non-ISP providers, however, to be fair, the former looks the most promising in the future. The technical problem addressed by the present invention arises when streaming services are provided to wireless (especially mobile) clients. [0002] For descriptive purposes, a list of ab...
