Abstract: Methods, systems, and devices are described for wireless communication to enable a UE to establish emergency services (e.g., IMS emergency calls) over WLAN (e.g., Wi-Fi) in 3GPP networks. Such mechanisms may help ensure that an ePDG capable of supporting emergency services is selected. Further, such mechanisms may help ensure that an appropriately located ePDG is selected. For example, the selected ePDG may be located in the visiting public land mobile network (VPLMN) for a roaming UE so that IMS emergency calls are routed appropriately. Selection of the ePDG may be under control of the network with which the UE is establishing connectivity for the emergency call, namely the VPLMN, as opposed to the home PLMN (HPLMN), for example. Such mechanisms may rely on knowledge that the connectivity being established is for emergency services, as well as other information regarding the UE, such as a current location of the UE.

Abstract: Methods and systems for adapting positioning reference signal (PRS) transmissions are disclosed. A server receives a request to support an emergency call associated with a user equipment (UE) and sends a first PRS schedule to a first base station, the first PRS schedule configured to enable the first base station to switch to a first emergency PRS mode and to transmit PRS signals according to the first PRS schedule. The base station establishes a PRS schedule, switches to an emergency PRS mode, and transmits PRS signals in accordance with the PRS schedule. A UE initiates an emergency call, receives positioning assistance data from a server, performs terrestrial radio location positioning measurements based on the received positioning assistance data, and provides the terrestrial radio location positioning measurements or a location computed from these measurements to the server.

Abstract: Example methods, apparatuses, or articles of manufacture are disclosed herein that may be utilized, in whole or in part, to facilitate or support one or more operations or techniques for utilizing a reference signal for indoor positioning, such as for use in or with a mobile communication device, for example. In an implementation, a reference signal may be focused into a directed beam, for example using a phased antenna array, and rotated electronically through a sequence of directional angles in a horizontal plane. A mobile device may determine a most probable directional angle from one or more transmitters transmitting a directional beam, measure one or more parameters for each directional angle and determine a location estimate using, for example triangulation.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus initiates a call attempt in an internet protocol multimedia subsystem (IMS) based on a dialed number, the dialed number including an emergency number. The apparatus receives a session initiation protocol (SIP) message in response to the call attempt. The apparatus determines in response to the SIP message whether to retry the call attempt as a normal call in a circuit-switched (CS) domain for an operator or as an emergency call in the CS domain for the operator. In an aspect, the determining is based at least in part on either an indication in the SIP message or on a characteristic of the operator.

Abstract: Certain aspects of the present disclosure relate to techniques for increasing the emergency call success rate by reducing the number of retries in a same domain. According to one aspect, a multi-mode user equipment may measure a first time period upon a first attempt of establishing an emergency call in a first RAT network. The UE may use a configurable parameter to determine a number of times that the UE may retry the emergency call in the first RAT network after expiration of the first time period without establishing the emergency call or after a failed attempt of the emergency call during the first time period. The UE may switch to a second RAT network if the UE fails in establishing the emergency call in the first RAT network after retrying the determined number of times.
