Call spoofing can be mitigated by providing geolocation information to the called device. For example, when a call rings, a geolocator can be invoked and the incoming call display screen can show a carrier logo and/or a geolocator globe illustrating the location of the call originator. The geolocation session initiation protocol data can be confirmed by a network device and compared against carrier specific data of the calling device to authenticate voice calls for called devices. In one embodiment location data of the calling device can purposely be shared in order to facilitate the mitigation of call spoofing.

Examples of systems and methods for bridging virtual and physical spaces are described. In some of these examples, a particular communicant's real world state drives changes in one or more of the communications connections, virtual state, and communications interface of the particular communicant or another communicant.

A method for sound source localization in a digital system having at least two audio capture devices is provided that includes receiving audio signals from the two audio capture devices, computing a signal-to-noise ratio (SNR) for each frequency band of a plurality of frequency bands in a processing frame of the audio signals, determining a frequency band weight for each frequency band of the plurality of frequency bands based on the SNR computed for the frequency band, computing an estimated time delay of arrival (TDOA) of sound for the processing frame using the frequency band weights, and converting the estimated TDOA to an angle representing sound direction.

Handling communications in a wireless network is described. A message requesting forwarding of communications for a first user device is received. Communications include telephone calls, video calls, text based communications, and messages sent via social media. The message requesting forwarding is sent in response to detecting a battery reaching or dropping below a predefined threshold power level. The location of the first user device is determined. One or more trusted second user devices associated with the first user device is identified based on a parameter indicating a highest predefined priority. A trusted second user device is selected to automatically receive redirected forwarded communications for the first user device. The selected second user device is located within a predefined distance of the location of the first user device. Forwarding is cancelled based on detection of normal battery status, or upon receiving a manual cancellation notification.

Systems, methods and computer program products for handling communications in a wireless network are described. A message requesting forwarding of communications for a first user device is received. A location of the first user device is determined. One or more second user devices associated with the first user device is identified. A second user device is selected to receive forwarded communications for the first user device. The selected second user device is located within a predefined distance of the location of the first user device. In example implementations, the one or more second user devices are trusted user devices.

A method of testing an emergency network, includes: simulating, by test logic, a public emergency network entity and a plurality of interfaces between the public emergency network entity and a test device; monitoring, by the test logic, the plurality of interfaces to determine that data flowed correctly on each interface in response to an emergency alert sent from the test device such that the emergency alert is not actually sent to the public emergency network entity; and determining, by the test logic, a test status for each interface indicating a success or failure of a test, for each interface, the test status based on data correctness such that the test confirms that the emergency alert and associated emergency data would be sent to the public emergency network entity correctly.

In an approach for recommending a response time for callback, a processor receives an indication to initiate a callback to a caller after the caller requests the callback from a callee, wherein the callee is a user whom the caller has called. A processor analyzes callback information. A processor determines a callback time based on the callback information. A processor sends an alert about the callback, wherein the alert includes the determined callback time.

Novel tools and techniques are provided for implementing prevention of foreign initiated fraudulent or unauthorized use of calling service. In various embodiments, a computing system might receive, from a first user device associated with an originating party, a request to access a first account of a calling system and an access code. Based on a determination that the received access code is valid, the computing system might determine whether the first user device associated with the originating party is located in a foreign country. If so, the computing system might determine whether a database contains a configurable flag indicating that international access is not allowed for the first account. If so, the computing system might initiate one or more first actions. If not, the computing system might provide the first user device with access to the first account of the calling system.

A system and method to establish and maintain a connection between devices, which in one example embodiment of a method, may comprise receiving a request to establish a connection between a first communication device and a second communication device. A determination is made as to whether the second communication device is reachable via a data network. Based on the determination that the second communication device is reachable over the data network, a connection between the first communication device and the second communication device is established via the data network. Based on the determination that the second communication device is not reachable over the data network, a connection between the first communication device and the second communication device is established via a telecommunications network. Additional systems and methods are described.

The present disclosure provides a system for intelligently sampling information, such as location, activities, etc. on device. Sampling and uploading of background context is optimized using machine learning, such that battery usage is reduced, and quality of metrics based on the reported information is maintained or improved. A policy is generated based on the machine learning, the policy dictating how scanning and upload rates should change in response to conditions on the device.
