Patent number: 6501956Abstract: The inventive system provides a user interface between a wireless communication device and an information service provider. The interface allows for a blended presentation of information and calling services for implementing an information service to a user of a wireless communication device. The user establishes an initial connection with a data network server to receive a particular service. The data network server sends a set of wireless protocol instructions to the user's mobile device. Based on these instructions, the mobile device will display information to the user which can be used to select a particular service. While preferably presenting a continuous display to the user, the wireless protocol instructions initiate a communication connection between the mobile device and a voice server with speech recognition capabilities.Type: GrantFiled: October 17, 2000Date of Patent: December 31, 2002Assignee: InterVoice Limited PartnershipInventors: Eric Weeren, Mike Watson, Daren Wilson
