An Active User Registry system includes a database which is integrated with the POTS network and a packet network to exploit the outstanding strengths of both of its constituents. The Active User Registry database is a dynamic data structure of all the ways in which one or more users can be reached via some type of communication network. A key feature of the Active User Registry is the ability to broker between a subscriber's request for communications contact information corresponding to a user and the user's preferences of being reached by various communications alternatives.

Active user registry

An Active User Registry system includes a database which is integrated with the POTS network and a packet network (such as the Internet, or a corporate intranet). Integrating AUR with the POTS network and a packet network exploits the outstanding strengths of both of its constituents, such as the low-latency, high reliability, moderate fidelity real-time voice telephony provided by the POTS network, and the point-and-click access to distributed databases with excellent search capabilities provided by a packet network, such as the Internet (including those made available using browser technology in conjunction with the World Wide Web). The AUR database contains a dynamic data structure (such as a linked list or a hashed table) of all the ways in which one or more users can be reached via some type of communication network (e.g., through the POTS network or a packet network, or both). A key feature of the AUR is the ability to broker between a subscriber's request for communications contact information corresponding to a user and the user's preferences of being reached by various communications alternatives. Other features may be included with the AUR, including an AUR cache which provides subscribers with rapid-access entry points into the AUR, or automatic updating of user contact information. Further, the capability of learning the user's preferences is included as an additional feature and is also included as a feature in an alternative embodiment of the present invention.

A method of reducing transmission delays in a packet-switched telephone system. Each of the data packets carrying telephone voice data is under-filled when necessary in order to avoid undue delays in sending the packets to their designation. Under-filling of the packets allows a routine telephone conversation to take place with out being adversely affected by network delays or delays normally attributed to the time needed to accumulate sufficient data to fill a packet to its normal size. Packets may also be filled to their normal size by combining data from more than one telephone call if the data from the other calls is immediately available. Filling an otherwise under-filled packet with data from multiple telephone calls avoids the inefficiencies which would otherwise be present with under-filled packets for a single call.

Method of reducing delays in packet data transmission

A method for the treatment of unrecognized words and phrases in spoken language translation systems is applicable to open-ended word or phrase categories, such as proper names, and involves the demarcation of one or more unrecognized segments from the input speech signal and splicing these segments into the appropriate position of the synthesized speech signal for the translation.
