A system for facilitating automated response to a distress signal includes an attachment for a multifunction mobile computing device. In some embodiments, the attachment removably articulates to a sensor location coupled to a housing of the multifunction mobile computing device. In some embodiments, the system includes a computer program product in a non-transitory computer-readable medium. In some embodiments, the program instructions are computer-executable by the multifunction mobile computing device to implement detecting a disarticulation of the attachment from the sensor location on the multifunction mobile computing device, and, responsive to the detecting the disarticulation of the attachment from the sensor location on the multifunction mobile computing device, transmitting to a distress signal response receiver over a radio-frequency network from a radio-frequency transmitter located within a housing of the multifunction mobile computing device the distress signal.

Systems and methods are described herein for handling E911 communications within IMS networks, such as Voice over LTE (VoLTE) networks. In some embodiments, the systems and methods, via various communication nodes, handle or otherwise govern emergency calls within the VoLTE network, by sending an INVITE message from a sender node of the VoLTE network to a recipient node of the VoLTE network, and starting a retry timer at the sender node that is specific to handling E911 calls by the VoLTE network.

Disclosed is an operating method of an M2M terminal which operates in idle mode by confirming that there is no additional data transmission, transmitting to a base station a message for requesting to maintain context information during a predetermined time period which a timer indicates, even when changing to the idle mode, and receiving from the base station a message instructing to enter the idle mode.

Various examples are provided for emergency services access devices. In one embodiment, a telecommunication device includes one or more buttons that, when activated, cause the telecommunications device to communicate a corresponding emergency communication to one or more emergency services. The device can be configured to contact emergency services at the push of a button to indicate the type and location of the emergency. The severity of the emergency can also be indicated. The device can be used in a larger connected device topology that would enable more advanced functionality.

A method and broadcast terminal for receiving an emergency alert message in a sleep mode, are discussed. In one embodiment, the method includes monitoring fast information channel (FIC) wake-up indicator in an FIC segment to determine if the broadcast terminal should be switched to an active mode to receive the emergency alert message; getting an FIC-Chunk payload responsive to the FIC wake-up indicator in the FIC segment, the FIC-Chunk payload including an emergency alert data package indicator; receiving an alert data indicated by a data package identification included in the FIC-Chunk payload, the emergency alert data package indicator indicating an emergency alert table describing the emergency alert message is carried in the data; and parsing the emergency alert message based on the emergency alert table.

A method for facilitating a safety check in emergency situations includes: storing a plurality of account profiles, each including a primary account number, account details, and sets of communication data; receiving a transaction message including a specific primary account number and an indication that an associated individual is safe; identifying a specific account profile that includes the specific primary account number; and transmitting a safety notification including the account details stored in the specific account profile the indication of the associated individual's safety for at least one of the sets of communication data stored in the specific account profile.

A method for identifying an unknown portable computing device within a specified radius is completed through a portable computing device and a plurality of communication towers that wirelessly communicate with the portable computing device. When a user of the portable computing device senses danger or an emergency, the user communicates with an arbitrary tower from the plurality of communication towers. The arbitrary tower receives a notification from the portable computing device which triggers the arbitrary tower to scan a radius of influence of the arbitrary tower. After scanning the radius of influence, the arbitrary tower saves a list of identification data for at least one unknown portable computing device. A list of location coordinates and a list of user data is saved along with the list of identification data. Therefore, the list of identification data can be later analyzed to recognize the user of the unknown portable computing device.

An all-group calling method, system, related device and computer storage medium, the method comprising: setting an all-group calling number at a terminal; and in an emergency, the terminal jointly establishes, according to the all-group calling number, an all-group call between terminals via a base station or the base station and a core network.

A message processing method, a node device, and user equipment is disclosed. A second node determines a first message, where the first message is used to instruct user equipment to receive a system message of a first node cell or used to indicate that a system message of a first node cell is updated; and the second node sends the first message to the user equipment. In accordance with the present disclosure, the user equipment can reside on the second node and be paged by the second node, and a first node does not need to perform paging, thereby reducing an air interface resource.

An improved method is provided for determining whether a sample point is within a defined geographic area. Indexes for the geographic area of interest are generated in advance. Such indexes complement the traditional spatial indexing techniques such as quad tree and r-tree. The geographic area, as defined by an outer boundary, is subdivided into some regular geometric shape, preferably a rectangle, encoded into a suitable form, and indexed. Then, a simplified comparison of the sample point to the indexed regular shapes is made.
