摘要:
An H.323 client terminal (102) according to an embodiment of the invention employs primary and secondary H.323 control units or state machines (110a, 110b). The primary control unit (110a) sends signaling messages to a primary gatekeeper (108a) and triggers the secondary control unit (110b) to send a message with an appropriate correlation identifier directly to a second client terminal. The primary control unit (110a) establishes a call per standard H.323 protocols. The secondary control unit (110b) also establishes a direct signaling connection to the second client terminal as back up. However, no media channels are established for this backup signaling. The secondary control unit (110b) checks the status of the call with the primary control unit (110a). If the call signaling on the primary control unit (110a) is proceeding normally, no further action is taken. If the call signaling with the primary gatekeeper (108a) fails, the secondary control unit (110b) takes over the signaling communication via the direct signaling channel.
摘要:
A telecommunications system includes a plurality of network clients (150) including a positioning controller (504) and a radio data network communications controller (502); and a positioning server (152) including a coordinating controller (161) for maintaining a database of network clients to be tracked and provide updates of position-related information to a presence server (104). The plurality of network clients (150) are configured to transmit position information received via said positioning controller to said positioning server via said radio data network communications controller (502).
摘要:
A wireless telephone includes a cellular telephone controller configured to interface the cellular telephone to a telephone network; a wireless packet network controller configured to interface the wireless telephone to one or more packet networks for voice over IP voice connection; and a wireless network access point controller configured to function as a wireless access point for interfacing a computer to said packet network via the telephone network; wherein the wireless packet network controller is configured to turn off a function of the wireless network access point controller if a packet network is detected.
摘要:
A context-based search system (3800) for control of a digital personal media stream manager (102), for example, to control the programming of a video recording device (114). Such a system may be maintained by a service provider and can identify a program and date and time without receiving complete details thereof; the DPVSM (102) can then control the recording of the program using IM or e-mail based-techniques. The context-based search system (3800) includes a message receiver (3902) for receiving the DPVSM message; one or more databases (3808, 3816) for storing keywords and program information; a confirmation message generator (3818) for informing the user of identified programming; and a DPVSM control (3820) for causing the DPVSM (102) to supervise the media recording once one of the identified results have been selected by the user.
摘要:
Reconfiguration operations in a networking environment are actively monitored to automatically detect faulty network traffic routing conditions, such as routing loop. The autodetection includes identifying a condition in which one of a number of routers is switched to a reconfiguration mode. In response, a network monitoring state is initiated in which operational parameters of each router are recurringly analyzed to detect an unexpected deviation that evidences the faulty network traffic condition.
摘要:
An electronic business card is provided with voice data associated with the card owner. In some embodiments, the voice data is a digitized voice sample; in other embodiments, the voice data is a selection of pre-processed voice recognition data associated with a voice sample. In some implementations, the electronic business card can be transferred to other parties using a Bluetooth personal network. A user application can then make use of the voice sample or pre-processed voice recognition data for security or user identification
摘要:
A dual mode packet phone is provided, comprising a first connector to connect the phone with a data network, and a second connector to connect the phone with a backup network. The phone automatically switches between the data and backup networks in the event that the data network fails to process the call in a timely manner. In a preferred embodiment, the phone is a Voice-over-IP phone, and comprises a voice processing unit, a control unit, a line interface, a data network interface, and a backup switch.
