Abstract

A method of wireless communication includes: an aggregator requesting a first description substream of a multimedia service from a source on a first path; receiving confirmation that the source is available; and receiving the first substream of the service. The method includes: determining whether the quality of the first sub-stream is satisfactory; and requesting to receive the multimedia service from the same source on at least one further path. A method of wireless communication by a source device comprising: receiving a request for a multimedia service from a terminal device aggregator on a first path; sending an acknowledgment that the source is available; and in response to the request, sending on the first path first substream. The method comprises receiving a request to transmit the multimedia service from the same source to the terminal device aggregator on at least one further path.

Description

technical field [0001] The present invention relates to communication networks, and more particularly to mobile multimedia services in wireless networks. Background technique [0002] The access link can often become the bottleneck of the WWAN (Wireless Wide Area Network). Currently, multimedia applications on mobile devices increasingly introduce higher traffic loads on WWAN access links, resulting in traffic congestion and unsatisfactory user experience. The capacity of the access link is subject to many constraints including physical channel conditions, maximum bit rate imposed by the operator based on service subscription, traffic load on the serving cell, and others. Although the capacity of the master node's access link may be limited at some time, the master node can use partner nodes to help enhance its access capacity. More specifically, the out-of-band link between the master node and its partner node, along with the partner node's access link, can provide an alt...
