Abstract: Methods and apparatuses for supporting location and emergency calls for an over-the-top (OTT) service provider are disclosed. A UE may send a request for an emergency call to an OTT service provider and may include in the request mobile network operator (MNO) data for a serving MNO for the UE. The OTT service provider may forward the emergency call request to an Internet Protocol (IP) Multimedia Subsystem (IMS). The IMS may determine routing information for the emergency call and either return the routing information to the OTT service provider to enable the OTT service provider to route the emergency call to a public safety answering point (PSAP) or may route the emergency call itself to the PSAP. The call request routed by the IMS or by the OTT service provider may include a reference identifier that may enable the PSAP to obtain a location for the UE from the IMS.

Abstract: Methods, systems, and devices are described for wireless communication. A wireless device such as an in-vehicle system (IVS) may transmit an emergency call (eCall) message to a third party eCall server using a communication session which may be packet based or circuit based. The eCall message may include session information and telematics data. The third party eCall server may relay the session information and telematics data to a public safety answering point (PSAP). For example, the third party eCall server may generate an automatic text-to-speech message that is transmitted to the PSAP over a public communications network. In some cases, the third party eCall server may transmit a response to the wireless device including metadata based on the telematics data transmitted in the eCall message. The eCall message may also include a call-back number, and the PSAP may contact the wireless device directly using the call-back number.

Abstract: Methods and apparatuses for providing support for location and emergency calls for an over-the-top (OTT) service provider (SP) are disclosed. An access network node receives a first message from a UE, determines a location reference for the UE, and sends a second message including the location reference to the UE. The access network node may determine the location reference itself on behalf of a location server or may request the location server to assign and return the location reference. The access network node may serve as a proxy and avoid interaction between the UE and the location server. The location server may later receive a location request for the UE from a network entity wherein the location request includes the location reference. The location server may locate the UE using the location reference and return the UE location to the network entity.

Abstract: Methods, systems, and apparatuses are described for asserting support for telematics capabilities in a vehicle emergency call system. In some aspects, a method for wireless communication in the vehicle emergency call system may include transmitting a set of telematics capabilities from a first endpoint in the vehicle emergency call system to a second endpoint in the vehicle emergency call system over a communication session signaling protocol.

Abstract: Disclosed is a device that includes a natural-gas compression system having a natural-gas powered combustion engine, a compression cylinder configured to receive natural gas and output compressed natural gas, a piston disposed in the compression cylinder and configured to translate through the compression cylinder in response to mechanical power received from the natural-gas powered combustion engine, and a variable-volume head mounted to the compression cylinder and configured to vary a compressed volume of the compression cylinder. In some instances, the variable-volume head includes a head body, an adjustment screw rotatably coupled to the head body, a plug moveable in threaded engagement with the adjustment screw, and an anti-rotation device coupled to the plug, the head body, or both. The anti-rotation device may be configured to impede the plug from rotating relative to the head body as the adjustment screw rotates.

Abstract: Methods, systems, apparatuses, and computer-readable mediums are described for techniques for supporting telematics-enhanced emergency calls from mobile phones. In some aspects, a method for wireless communication may include establishing, by a user equipment (UE), a personal telematics-enhanced emergency call to a public safety answering point (PSAP), wherein the UE is capable of transmitting telematics data. The method may also include transmitting information that distinguishes the personal telematics-enhanced emergency call from other types of emergency calls.

Abstract: Methods, systems, and devices are described for communicating telematics data and metadata. A first device transmits a first signaling message to a second device over a communication session signaling protocol.

Abstract: Systems and methods provide a discovery protocol allowing nodes that are interested in knowing a network topology to discover other nodes in the network topology. The discovery protocol includes two message types, topology discovery messages and topology query messages. A node issues topology discovery messages upon powering up, at periodic intervals, or upon detecting a change in network topology. The topology discovery messages are broadcast to all nodes on a network and identify the issuing node to the network. A topology query message is sent to a particular node and requests a response from the receiving node regarding the neighboring nodes of the receiving node. The querying node can use the response data to discover other nodes and to send the discovered nodes query messages such that the node can determine a network topology to a desired level of depth within the network.
