Disclosed in the present invention is a VoLTE-based voice call method. The method comprises: a calling terminal determining whether a VoLTE call mode is activated: if so, the calling terminal generating a call request, the call request comprising contact card information of the calling terminal; and the calling terminal sending the call request to the called terminal, so as to enable the called terminal to acquire the contact card information of the calling terminal from the call request. The present invention can facilitate users to exchange contact card information.

A redirection and messaging system receives telephony information identifying a caller and call context from a telephony system. The system selects one of a plurality of messaging operators based on the call context, optionally sends an introductory message to the caller via a messaging service, and generates a message interface for the selected message operator. The message interface includes the caller and call context and any messages sent between the caller and the selected message operator, with an input interface allowing the selected message operator to input and send messages to the caller.

A method and system for collecting and verifying the location information of a calling party and a device of the calling party is provided. More specifically, a method and system is provided for determining whether the identity of the calling party can be confirmed, via evaluating location information, with an acceptable degree of certainty. The location information may be provided by the calling party or obtained from various sources over a digital communication channel. Some of the provided location information which can be accidentally or intentionally altered is identified and evaluated to determine its accuracy as part of the verification process of the caller's identity.

A redirection and messaging system receives telephony information identifying a caller and call context from a telephony system. The system selects one of a plurality of messaging operators based on the call context, optionally sends an introductory message to the caller via a messaging service, and generates a message interface for the selected message operator. The message interface includes the caller and call context and any messages sent between the caller and the selected message operator, with an input interface allowing the selected message operator to input and send messages to the caller.

An activation device includes a wireless communication interface, an activation circuitry, and a trigger device. The wireless communication interface is configured to communicate with a mobile phone in a personal area network. The activation circuitry is configured to generate a signal for activating the mobile phone. The trigger device is configured to receive an input from a user. When the trigger device receives the input from the user, the activation circuitry is caused to generate the signal, and the wireless communication interface is configured to send the signal to the mobile phone, causing the mobile phone to pass the call request to a call service, which is in turn caused to generate a call, calling the mobile phone.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for receiving, from a computer system, a request comprising a phone number, identifying a primary channel and one or more secondary channels based on, at least in part, respective performance data of the primary and secondary channels, sending a first message comprising a first text string via the primary channel to a destination device associated with the phone number, after sending the first message, determining that a conversion event for the message and the primary channel did not occur within a specified time period, and based on the determining, sending a second message comprising the first text string via a particular secondary channel to the destination device.

A mechanism is provided for implementing an emergency response cognitive computing system. The emergency response cognitive computing system identifies a first party about which a communication is being performed between a caller and the emergency response system. The emergency response cognitive computing system generates, in real-time, a transcript of the communication as the communication is being conducted. The emergency response cognitive computing system performs natural language processing on the transcript of the communication to identify portions of content corresponding to medical concepts. The emergency response cognitive computing system processes patient information to identify elements of the patient information referencing concepts corresponding to medical concepts. The emergency response cognitive computing system outputs the elements of the patient information to a second party involved in the communication.

Disclosed herein are methods and systems for discovering an MSISDN of a cellular device, comprising detecting an activation event of the cellular device with a SIM associated with an MSISDN not exposed to the cellular device, transmitting one or more discovery Short Message Service (SMS) messages to a discovery system configured to transmit back to the cellular device one or more response SMS messages comprising the MSISDN identified for the discovery SMS message(s), receiving the response SMS message(s), and storing the MSISDN extracted from the response SMS message(s). The cellular device includes the stored MSISDN and a location of the cellular device in one or more Advanced Mobile Location (AML) messages transmitted by the cellular device to an AML service when initiating an emergency call.

A method for authentication, a user terminal and an authentication server for executing the same are disclosed. An authentication server according to an embodiment disclosed includes a number receiver that receives a number of a user terminal from a callee who has received a call originated from the user terminal, a device authenticator that determines whether to generate an authentication key based on the number of the user terminal received from the callee and a caller number received from the user terminal, and generates the authentication key when it is determined to generate the authentication key, and an authentication key transmitter that transmits the authentication key to the user terminal.

A system and method of determining pre-verification information for use by a certification authority to verify and attest phone numbers associated with healthcare facilities is provided. The method includes receiving an unverified phone number and determining, using one or more matching operations, whether the unverified phone number is associated with a healthcare facility. In response to such determination, the unverified phone number and a facility name associated with the healthcare facility is sent to a certification authority server to be used to verify the unverified phone number. Other embodiments are described and claimed.
