Publication number: 20240357707Abstract: Solutions for placing an emergency call over a wireless network improve speed and reliability by prioritizing using an internet protocol (IP) multimedia subsystem (IMS) packet data network (PDN) or protocol data unit (PDU) network (PDN/PDU) over domain reselection when a call attempt fails over an emergency PDN/PDU (EPDN/EPDU). Examples include establishing an IMS PDN/PDU session for a user equipment (UE) over a wireless network; attempting, by the UE, an emergency call using an EPDN/EPDU over the wireless network; and based on at least a failure of the emergency call over the EPDN/EPDU, reattempting the emergency call using the IMS PDN/PDU over the wireless network. Based on at least a failure of the emergency call over the IMS PDN/PDU, the UE performs domain reselection and reattempts the emergency call using a second wireless network. In some examples, wireless networks transmit a network policy for handling the emergency call to the UE.Type: ApplicationFiled: April 19, 2023Publication date: October 24, 2024Inventors: Hang Hoi Yau, Christopher Joul, Hyung Keun Choi, Lin Zhang, Syed Hassan Raza, William Hooker, Srinivasa Rao Bodapotula, Anthony James Wageman

Publication number: 20240267706Abstract: Systems, methods, and computer-readable media are provided for calculating a location of user equipment (UE) prior to communicating an SMS message to an emergency number. More particularly, additional time is provided to location services so a complete location can be determined, prior to an SMS message being composed and communicated to emergency services. To do so, the UE transitions into an emergency mode as soon as the recipient of the text message is identified as an emergency number (e.g., 911). This immediately causes the UE to unblock all numbers (i.e., in case emergency services needs to initiate a voice call to the UE), enable location services, and initiate a location calculation. As a result, the location calculation is already determined by the time the user composes the text hits send.Type: ApplicationFiled: February 7, 2023Publication date: August 8, 2024Inventors: Zaheer Mohammed Siddique, Hyung Keun Choi

Publication number: 20240267718Abstract: Systems, methods, and computer-readable media are provided for delaying communication of a short message service (SMS) message to an emergency number until a location of user equipment (UE) is determined. To do so, a timer is started as soon as the user hits send for SMS to an emergency number. The location is recalculated until the timer runs out or the desired location uncertainty is achieved. For example, if the timer is still running and the location uncertainty is greater than a pre-configured threshold, the UE keeps recalculating the location. Once the location uncertainty is equal to or below the pre-configured threshold, or the timer runs out, the location and the SMS message are communicated to the emergency number.Type: ApplicationFiled: February 7, 2023Publication date: August 8, 2024Inventors: Zaheer Mohammed Siddique, Hyung Keun Choi
