Priority registration for in-vehicle emergency call service |
摘要 |
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. |
