| 20080292065 | Single Point of Contact Personal Communication System - A computer/telephony integrated single-point-of-contact system (CISS) enabling a user to contact another using multiple devices with a single contact attempt is disclosed. A plurality of computer programs residing in a computer use a subscriber database, authorization database, priority list database, and device attributes database to determine how to respond to a request to contact a subscriber. If the request is an emergency, the computer repeatedly contacts all of the subscriber's devices until a response is received. Otherwise, the computer contacts the subscriber's devices in a sequential order determined by the subscriber. The computer can also delete redundant un-received messages from a subscriber's devices and create a real-time connection between the requester and the subscriber, if it is technically possible, at the subscriber's request. | 11-27-2008 |
| 20090147929 | METHOD AND APPARATUS FOR TRANSMIT-RECEIVING EMERGENCY SERVICE - Methods and apparatuses for transmitting and receiving emergency service are provided to solve the problem that the user maliciously performs emergency registration with the emergency user ID to receive the unauthorized service. The method for initiating callback in the emergency service includes forwarding the request message to the callee connection network and informing the callee connection network of the identity of the initiator identity after the callback initiator side authenticates the identity of the initiator of the received request message. The method for receiving callback in the emergency service includes: recognizing, by the callee connection network, the identity of the initiator who initiates the callback request message transmitted from the call initiator-side network and performing post-processing according to whether the identity of the initiator is a valid PSAP. | 06-11-2009 |
| 20090296901 | FORCED ANSWER COMMUNICATIONS - Apparatus, systems, and methods may operate to implement forced answer communications by receiving a request to permit emergency activation of a first telephone in response to a call placed by a second telephone having a defined telephone number, receiving the call placed by the second telephone to the first telephone, wherein the first telephone is either on hook or turned off, and establishing a voice communication path between the first telephone and the second telephone. The path may be established by either sending an off hook command to the first telephone if the first telephone is turned on and on hook, or sending a combination of turn on and off hook commands to the first telephone if the first telephone is turned off. Additional apparatus, systems, and methods are disclosed. | 12-03-2009 |
| 20100027764 | NETWORK DEVICE AND METHOD FOR REDIALING PHONE CALLS - A network device, configured with common and emergency call resources for connecting a telephone terminal to a local exchange, includes a storage module, a control module, and a digital signal processor. The storage module stores a plurality of emergency call numbers. The control module detects a public switched telephone network (PSTN) dialing signal from the telephone terminal and determines if the common call resource has been exhausted upon detecting the PSTN dialing signal. The digital signal processor receives a PSTN call number from the telephone terminal upon the condition that the common call resource has been exhausted, determines if the PSTN call number matches with one of the emergency call numbers, and redials the PSTN call number to the local exchange via the emergency call resource upon the condition that the PSTN call number matches with one of the emergency call numbers. | 02-04-2010 |
| 20100266107 | EMERGENCY CALL HANDLING IN ACCORDANCE WITH AUTHENTICATION PROCEDURE IN COMMUNICATION NETWORK - Techniques are provided for handling of an emergency call as it affects an authentication procedure in a communication network. For example, it is assumed that, in a communication network, a first computing device comprises user equipment and a second computing device comprises an authentication function. Thus, a method comprises the following steps. A first type call indicator message is received at the second computing device from the first computing device. A decision is made to proceed with or drop an authentication procedure for the first computing device at the second computing device based on the first type call indicator message. The second computing device may enable a first type call to be placed for the first computing device. The first type call may be an emergency call. | 10-21-2010 |
| 20120082302 | SYSTEMS AND METHODS FOR FACILITATING EMERGENCY CALLBACKS - Systems and methods for facilitating emergency callbacks are provided. A request to permit the connection of a telephone call originated by a user device may be received by a call processing system. The call processing system may include any number of computers or computing devices. The telephone call may be identified by the call processing system as an emergency call. Based upon the identification, the call processing system may override one or more incoming call parameters to permit connection of a return call to the user device. | 04-05-2012 |
| 20120163561 | Method, device and system for implementing emergency call override service - The present disclosure provides a method, device and system for implementing emergency call override service; wherein the implementation method comprise: a first application server (AS) on a called side receives an initial request message, carrying a service identifier indicating an emergency call override service, from a second AS on a calling side; and the first AS implements the emergency call override service according to the service identifier. In the IMS network architecture, by adding a service identifier, indicating emergency call override service, in an initial request message based on SIP, an AS network element on a called side can implement emergency call override service according to the service identifier, thereby solving the problem that the emergency call override service cannot be implemented in the current IMS network architecture. | 06-28-2012 |
| 20120163562 | COMMUNICATION APPARATUS - A communication apparatus comprises: a disaster information receiving section connected to a communication line for receiving disaster information therefrom; a microphone; a speech recognizing section for recognizing speeches input from the microphone; a communication section; and a control section. When the disaster information receiving section receives disaster information from the communication line, the speech recognizing section starts recognizing speeches from the microphone. When the speech recognizing section recognizes the presence of the speeches from the microphone, the control section controls the communication section to make a call to a predetermined destination of communication. | 06-28-2012 |
| 20130216028 | NETWORK TO ALARM PANEL SIMULATOR FOR VOIP - The present invention provides for a system and method for providing a signal to a communication system comprising an interface between a communication link and the communication system, like an alarm system, wherein the interface receives a signal from the communication link and provides a signal indicative of the availability of the communication link for use by the communication system. Alarm systems operations may be facilitated so that Residential Gateway components (such as voice terminal adapters) may simulate traditional telephone network systems that run on 48 VDC powered telephone lines. The system also comprises an input port associated with the interface for receiving the signal from the communication link, a transformer or a voltage regulator and an output port associated with the interface for providing the conditioned signal to the communication system. A ring voltage received from the communication link may be passed through to the alarm system. | 08-22-2013 |
| 20130230153 | IDENTIFICATION AND DETERMINATION OF NON-PREEMPTABLE CALLS - An active call between two parties can be marked as a non-preemptable call if one of the two parties is an authorized agency that desires to prevent premature termination of the call by a third party. The authorized agency sends a signal to a main switch to indicate that non-preemptable call status is desired. The newly established call status is then propagated to other nodes in the system to prevent premature call termination. Non-preemptable status can also be granted to some calls based on the destination of the called number, such as in 911 calls. | 09-05-2013 |
