Abstract: A UE may receive input indicating an attempt to place an emergency call. The UE may communicate with a first cellular network to connect the emergency call. The UE may generate a first SIP header, the SIP header including first location data indicating a first location of the UE. The UE may transmit the SIP header including the first location data via a user plane function of the first cellular network. While the emergency call is ongoing, the UE may disconnect from the first cellular network and connect to a second cellular network. The UE may communicate with the second cellular network to continue the emergency call. The UE may then generate a second SIP header including second location data indicating a second location of the UE. The UE may transmit the second SIP header including the second location data via the user plane function of the first cellular network.

Abstract: A method may include receiving, by a radio unit (RU), a mobile communication from a user device, the RU associated with a cell identifier (CID). The method may include determining, by an access and mobility function (AMF), an attribute associated with the user device and the mobile communication. The method may include generating, by a core network function, a communication record of the mobile communication including the CID and the attribute. The method may include storing, by a computing device, the communication record in a database. The method may include receiving, by the computing device, a request for communication records including a requested attribute type. The method may then include determining, by the computing device, that the attribute of the communication record is of the requested attribute type. The method may include transmitting, by the computing device of the cellular network, the communication record based on the request.

Abstract: A presentation system provides a for an audience display and a mobile wireless device operates to reserve a portion of the display screen of the mobile wireless device that is not mirrored to the audience display allowing ancillary functions of the mobile wireless device to be accessible during a presentation without visibility to the audience. Image output data from these functions may be dragged into the portion of the display that is mirrored. Those ancillary functions may include presentation specific functions such as pointers, drawing program tools, keyboards and the like, or more generally other tasks executable on the mobile wireless device.
