Abstract

A system and method permits a wireless communication terminal (such as a mobile telephone) to access Internet audio services. The wireless terminal communicates in WAP protocol to a WTA Internet server acting as a gateway between a mobile network and a wired network, and requests a channel to an audio service residing on a particular Internet origin server. The WTA server initiates establishment of an audio channel with the origin server. The WTA server also instructs the wireless terminal to answer automatically the next voice telephone call it receives, and the WTA server instructs the mobile network to place a voice phone call to the wireless terminal. The wireless terminal automatically answers, and there is then established a speech path from the wireless terminal, over the mobile network, through the WTA server, to the origin server. The wireless terminal may access the Internet audio service over this audio path.

Dependent claims

A method of wireless access to a wired-network-based audio service from a wireless terminal, comprising the steps of:

(a) sending, from the wireless terminal in a wireless network to a network gateway server, a request identifying an audio service residing on an origin server in a wired network;
(b) sending, from the network gateway server to the origin server, a request for an audio channel to the audio service;
(c) setting up in the origin server the requested audio channel between the origin server and the network gateway server in the wired network;
(d) sending, from the network gateway server to a mobile network, an instruction to place a mobile voice call in the wireless network between the wireless terminal and the network gateway server;
(e) sending notification from the mobile network that the wireless terminal has answered the voice call;
and
(f) performing, in the network gateway server, digital conversion of audio data flow formats between the mobile voice call in the wireless network and the audio channel in the wired network, wherein a speech path is established from the wireless terminal through the mobile voice call to the network gateway server and from the network gateway server through the audio channel to the audio service on the origin server over which audio transmission may take place.
