Method to stream compressed digital audio over circuit switched, voice networks

摘要

A system and a method for streaming audio data to a plurality of callers in a telecommunication system have been disclosed. The system facilitates streaming of audio data to a plurality of callers by establishing a single connection with an audio data publisher. The system receives the audio data from the audio data publisher over the internet or a similar network and streams the audio data to a plurality of callers over a telecommunication network. The audio data can be streamed to a caller as a ring-back tone of a callee.

主权项

1. A method for streaming audio data to multiple callers, the multiple callers being connected to a telecommunication infrastructure, each of the multiple callers having initiated a call session with a respective callee in the telecommunication infrastructure, the method comprising the steps of:
a) receiving a callee ring back tone (RBT) information; b) identifying a broadcasting server from a plurality of broadcasting servers connected to an audio data source based on the callee ring back tone information; c) checking for an established connection with the identified broadcasting server connected to the audio data source, wherein the connection is established over a packet switched network; d) receiving the audio data through the established connection with the broadcasting server connected to the audio data source over the packet switched network; e) replicating the received audio data to generate a plurality of data streams, each data stream comprising the received audio data: f) simultaneously streaming, as an RBT during RBT playback time of the call session, each of the plurality of generated data streams to each of the multiple callers over a circuit switched network.
