Embodiment Construction

[0024] Techniques for supporting eCall are described herein. An eCall is an emergency call in which: (i) the emergency call may be initiated automatically by the wireless terminal or manually by the user due to a triggering event (e.g., the vehicle being involved in an accident); and (ii) The emergency call contains additional data that is automatically sent by the terminal to a receiving entity (eg, a Public Safety Answering Point (PSAP)). The additional data may include VIN, vehicle location, triggering events, etc., and may be sent in-band along the voice path, or out-of-band via separate signaling or data / text transfers. data. A terminal supporting eCall may be a terminal as follows: (i) a conventional wireless terminal, which subscribes to conventional services such as voice calls, packet data, text messages, video, etc.; or (ii) an eCall-only terminal, which is called a eCall terminal. An eCall consists of: an emergency call (similar to one initiated by a user dialing...

Abstract

An eCall is an emergency call that may (i) be initiated automatically by a wireless terminal due to a trigger event (e.g., a vehicle involved in an accident) or manually by a user and (ii) include additional data sent automatically by the terminal to a recipient entity, e.g., a Public Safety Answering Point (PSAP). Emergency setup signaling (e.g., an Emergency SETUP message) is used to give high priority to registering an eCall-only mode In-Vehicle System (IVS) on a mobile network. The IVS can get higher priority from the mobile network right after an eCall emergency is triggered at the IVS. When requesting a connection to the mobile network, the IVS can use an "emergency setup" message instead of a conventional "registration" message in order to register on the network.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and rights to Provisional Patent Application No. 61 / 485,076, filed May 11, 2011, and Provisional Patent Application No. 61 / 555,293, filed November 3, 2011. The entire contents of these provisional patent applications are hereby expressly incorporated herein by reference. [0003] technical field Background technique [0004] Wireless communication networks are widely deployed to provide various communication services such as voice, video, packet data, messaging, broadcast, and so on. These wireless networks may be multiple-access networks capable of supporting multiple users by sharing the available network resources. Examples of such multiple-access networks include Code Division Multiple Access (CDMA) networks, Time Division Multiple Access (TDMA) networks, Frequency Division Multiple Access (FDMA) networks, Orthogonal FDMA (OFDMA) networks, and Single-Carrier FDMA (SC-FDMA) networ...
