Method and apparatus for establishing a link in a wireless communication system
First Claim
1. A method of establishing a link between a mobile station in a wireless communication system and a speech recognition system, the method comprising the steps of:
- establishing a link between a base station system within the wireless communication system and the mobile station implementing a codec in the mobile station compatible with speech;
determining, in the base station system, that the mobile station requires a link to the speech recognition system;
establishing a link from the base station system to the speech recognition system implementing speech coding functions in the base station system;
instructing, from the base station system, the mobile station to change from the codec compatible with speech to a codec compatible with speech recognition; and
establishing the link between the mobile station and the speech recognition system after the mobile station changes to the codec compatible with speech recognition.

Abstract
A base station system (203, 303) in a wireless communication system (208, 308) establishes a link between a mobile station (200, 300) and a speech recognition system (209, 312). When the base station system (203, 303) determines that such a connection is required, the base station system (203, 303) instructs the mobile station (200, 300) to switch from a first codec (201) specific to human speech to a second codec (202) specific to speech recognition. Only after the switch between codecs in the mobile station (200, 300) does the base station system (203, 303) establish the link between the mobile station (200, 300) and the speech recognition system (209, 312).

8. A wireless communication system interfacing with a speech recognition system, the wireless communication system comprising:
-
means for establishing a speech communication between a base station system within the wireless communication system and a mobile station compatible with the wireless communication system, the speech communication implementing speech coding functions in the base station system and a codec in the mobile station compatible with speech; means for determining that the mobile station requires connection to the speech recognition system; means for instructing the mobile station to change from the codec in the mobile station compatible with speech to a codec compatible with speech recognition; and means for coupling the mobile station to the speech recognition system after the mobile station has been instructed to change from the codec compatible with speech to the codec compatible with speech recognition. - View Dependent Claims (9, 10, 11, 12, 13, 14)
