Abstract:
1. A method for providing services in a communication network, wherein, at a side of a service providing device, comprising steps of receiving a request message for a service, data of which is encoded into a plurality of layers by using layer coding; in response to said request message, sending a response message, wherein, said response message comprises a single connection identifier corresponding to one layer among the plurality of layers and a number of the plurality of layers for determining connection identifiers for said plurality of layers, wherein, each connection identifier uniquely identifies a service connection, and each layer of the plurality of layers corresponds to a service connection for transmitting its data; and sending data of said plurality of layers of said service through service connections identified by connection identifiers determined from the single connection identifier corresponding to one layer among the plurality of layers and the number of the plurality of layers wherein, an individual modulation and coding scheme corresponds to each of said plurality of layers and said plurality of layers contain a base layer containing minimum information for intelligibility and at least one enhancement layer containing additional information that incrementally improves overall quality of the service.
