A communication system is provided that uses loosely-coupled client-server architectures to improve the efficiency of communications. The communication system includes client and facilitator applications. The client application is a component of processor-based mobile communication devices. The facilitator application is hosted on one or more servers or other processor-based devices, and communicates with the client application via one or more couplings. The facilitator application can also be distributed among one or more portable processor-based devices including the communication devices hosting the client application. The communication system improves efficiency of voice communications by allowing communication device users to dynamically manage how and when mobile calls take place, intelligently screen calls based on caller identity, urgency, and subject matter, determine which contacts in a directory are available to talk and which ones choose not to be disturbed, and increase accessibility of enterprise and personal contact information from mobile phones.

A system is disclosed for the automatic detection of fraudulent activity on a transaction network, for which each transaction over the network has an associated identifier. In one embodiment, the system includes voice comparison means for comparing a first sampled voice of a user of a first transaction with a subsequently sampled voice of a user of a subsequent transaction having an identical identifier to that of the first transaction. Control means in the form of a voice-based fraud detection engine is provided for determining, from said comparison, a profile of user usage that is representative of a total number of different users of the associated identifier. In a preferred embodiment, the system also includes voice sampling means for sampling a voice of the user of the first transaction to generate a first voice sample.

A system and method are provided for controlling communications privacy in a Home Network telephone system. The method comprises: using a gateway to send and receive calls on at least one external telephone line; supplying privacy and public mode bridging options; and, selectively excluding bridges between external telephone lines and a plurality of Home Network endpoints. In response to the privacy mode being selected, the gateway bridges a call between a first external telephone line and a first endpoint, and prevents bridges between the first external telephone line and other endpoints in the system. Alternately, when the public mode is selected, the gateway bridges a call between the first external telephone line and the first endpoint; and permits bridges between the first external telephone line and other endpoints in the system. That is, while the call is bridged to the first endpoint, a bridge is added between the first telephone line and the second endpoint. The privacy and public mode bridging options are selected with respect to nodes. A node can be an external telephone line or an endpoint. That is, a privacy or public mode of operation can be selected for a first external telephone line, whether calls are received or originated through the Home Network telephone system. Likewise, a privacy or public mode of operation can be selected for a particular endpoint, regardless of whether the endpoint receives or originates the call.

An interface engine that is communicatively connected to a packet-switched network and to a legacy circuit-switched network uses a call processing protocol, such as the session initiation protocol (SIP), for packet-switched network communications and uses a legacy signaling protocol, such as IS-41, for legacy circuit-switched communications. In response to a registration request initiated by a subscriber device on the packet-switched network, the interface engine obtains a service profile for the subscriber from a call processing system, such as a home location register (HLR), of the legacy circuit-switched network. Service parameters derived from the service profile and stored in a service database may be used to apply services on the packet-switched network for the subscriber device.

An approach for monitoring interaction between individuals engaged in a communication session is disclosed. The individuals are described herein as a customer service representative and a customer and the communication session is accomplished over a communication network. Audio data embodying the communication session is copied and stored to a media file in conjunction with video data captured by a video capture device monitoring the customer service representative. The media file is a data structure in which the audio data and the video data are stored in segmented fashion. Each segment of audio data is associated with a segment of video data based on a common time reference, thereby providing synchronized documentation of the communication session. The media file is stored on a database and available to a supervisor using a server computer to monitor the communication session for quality assurance or other evaluation purposes.

The method provides a plurality of communication connections operable on at least one communication system, and each of the plurality of communication link comprises a plurality of metrics. The method further determines by the client device whether each of the plurality of communication connections is active, and evaluates each of the plurality of metrics for each of the active communication connections, and orders sequentially the plurality of active communication connections based on at least one of the plurality of evaluated metrics.

A method and apparatus for determining what level of performance must be maintained by a second communication service so as to be perceived as being of equal quality to a first communication service, especially where the second communication service is subject to additional impairments not experienced by the first communication service. In one example embodiment, the present invention is applied to determining what combinations of packet loss rate and packet delay are tolerable where a packet switched telephony service is desired to be perceived to be substantially equivalent to a traditional toll-quality non-packet-switched telephone service. Empirically derived models are used to relate user perception to objectively measurable characteristics, such as packet loss rate.

The present invention provides geographically fixed receiver functionality for subscriber information which specifies the subscriber's identity in a mobile telecommunications system. This is achieved in accordance with the present invention by associating the Subscriber Identification Information (SII) with a fixed geographical reference point rather than with a particular device. In accordance with one embodiment of the present invention the access point lies outside the radio telecommunications system. In this embodiment, the control signals of the mobile system must be transmitted right up to the subscriber's premises. In a further preferred embodiment the access point lies in the radio telecommunications system. In the latter embodiment, the control signals of the mobile telecommunications system may be terminated in an access node which may be conveniently located in a wired base station. In this embodiment, the control signals of the mobile telecommunications system are not transmitted to the customer premises. Also, the voice coding typically used in mobile telecommunications systems may be terminated at the access node and not at the customer premises. In another embodiment of the invention, the functions of the access node of the previous embodiment is shared between an access base station and a responder on the customer's premises. The responder is capable of responding to certain inquiries initiated in the wireless network, e.g. to provide subscriber identity information or to provide the result of an encryption algorithm carried out on a random number supplied from the wireless network.

A communication-status notification apparatus enabling a subscriber to observe various kinds of communication status in a network easily via the subscriber's own terminal in a communication system. The apparatus includes a request analysis section for discriminating whether or not voice data received by gateway equipment from a subscriber terminal contains a request on monitoring/controlling or notifying of a communication status in the network and for analyzing the content of the request when contains, a communication-status monitor/control section for monitoring/controlling the communication status responsive to the content of the request analyzed by the request analysis section based on a processing status of the voice data in the gateway equipment, and a communication-status notification section for notifying the subscriber terminal of the communication status monitored/controlled by the communication-status monitor/control section via the gateway equipment responsive to the content of the request analyzed by the request analysis section. The apparatus is useful when applied to VoIP gateway equipment or the like used for a VoIP communication system.
