ABSTRACT:
FIELD OF THE INVENTION
This invention generally relates to the field of Analog Display Services Interface (ADSI) devices and systems and in particular to a system and method to download computer network information to an ADSI feature telephone.
BACKGROUND OF THE INVENTION
ADSI is a telecommunications protocol standard developed by Bellcore. ADSI enables alternate voice and data capability over the existing analog telephone network. This capability permits ADSI telephones to communicate with users through a familiar voice response audio interface, where the user listens to voice recordings and makes menu selections using a telephone keypad, and with visual menus and information on a screen display, where service selections can be made using soft keys.
In addition to real-time interactive applications, ADSI also enables program transfer using a capability known as Feature Download. These programs, or service scripts, can be developed on a server and run on a local terminal. In many cases, these scripts are stored in an external database accessible to one telephony platform and for access by the telephony platform serving the user. Therefore, when new features are requested by the user, or are newly added by the server, the scripts are transferred by the telephony platform to the ADSI These scripts define not only call flow, but also define the soft keys and displays presented to the user during a call.
One example of applied ADSI technology is Northern Telecom's Advanced Call Management Service (ACMS). In ACMS, customer selected features are stored in an external database. When a customer calls in for activation of services, a database lookup is performed so that the appropriate information for that customer can be downloaded to the telephone. The application runs on a Network Applications Vehicle (NAV), that is typically a UNIX-based telephony platform, and reads an object file to get information concerning the call flow. The NAV presents the call flow, including ADSI commands, to the end user and as a result a new application is presented to the terminal.
Some telephone networks operate a UNIX-based telephony platform that can operate ADSI technology (ADSI telephone networks). Other telephone networks operate on less advanced telephony platforms that cannot operate ADSI technology. Their users are excluded from the opportunity to use ADSI technology by their telephone network.
It is cumbersome and costly to change download files on a NAV. It is also impractical to provide custom download files with caller selected information. Nevertheless, there is an unmet need for such download services.
SUMMARY OF THE INVENTION
The present invention is an ADSI download method and system. The system comprises at least one ADSI telephone with a display terminal, a telephony server, and one or more hosts on a computer network. The hosts contain one or more data files in mergable format such as plain text. As such, each data file is compatible with the 40 character line display of the ADSI terminal. The telephony server will merge the data file into an ADSI download template. The template consists of an ADSI download library with predefined blank pages of text which the server will fill in with the text from the data file prior to download to the ADSI telephone. The ADSI telephone has one or more memory locations for storing downloaded ADSI files. The files are received in accordance with a server initiated download or a caller initiated download. The ADSI telephone is connected to a customary telephone network. A telephone network server is selectively connected to one or more remote sites on one or more computer networks, including and not limited to the World Wide Web (WWW) of the Internet. The network application server accesses the remote site comprising at least one data file which the telephony server can process into a download for the ADSI device. The file(s) at the accessed site are downloaded to the server, merged into an ADSI download, and then downloaded to the ADSI caller's telephone by means of the telephone network. The caller on the ADSI telephone selects the information downloaded from the remote site by subscribing to certain types of information such as weather, stock quotes, news, etc. via their telephone service provider. Subscription to a service such as daily weather could be made by phone, or through a world wide web based form. The user of the ADSI phone could check off information they wished to be displayed on their phone, or enter in HTTP addresses where information could be fetched from. When preparing a download for the callers ADSI phone, the telephony server will fetch each data file the subscriber has specified, concatenate them, and process them into a form suitable for download into an ADSI phone slot where the information would be displayable.
