Embodiment Construction

[0017] "112" is the main emergency telephone number that can be dialed free of charge from any telephone or any mobile phone in the European Union (EU) for emergency services such as ambulance, firefighter and police services. The GSM mobile phone standard also designates 112 as an emergency number, so it will be available in North America (where the GSM system redirects emergency calls to the US equivalent of 911, 112) and Australia (where emergency calls are redirected to 000, 112) equivalent number) works on any GSM phone. "E112" is a location-enhanced version of 112, designed specifically for mobile phones, where the caller's location information is determined and transmitted to emergency centers (similar to the enhanced 911 or "e911" system in the United States).

[0018] "eCall" refers to the interoperable in-vehicle emergency call service established on the E112 system operating in Europe. The purpose of eCall is to speed up emergency services response times for road a...

Abstract

The home public land mobile network HPLMN or home network immediately accepts registration requests from "e-call only" subscribers attempting to register with any visitor public land mobile network VPLMN or roaming network. This avoids unnecessary delays in setting up an e-call (emergency call) that would otherwise be introduced by the home network's roaming registration management policy RRMP, which would otherwise only permit the registration of preferred roaming VPLMN companions (and subsequent call service), and automatically reject registrations from non-preferred roaming networks (which can hinder or prevent timely completion of e-calls).

Description

[0001] Claiming priority under 35 U.S.C. § 119 [0002] This patent application claims priority to Provisional Application No. 61 / 485,082, filed on May 11, 2011 and assigned to the present assignee and hereby expressly incorporated herein by reference. technical field Background technique [0003] eCall (eCall) refers to an in-vehicle emergency call service. In the event of a collision involving a vehicle, the eCall In-Vehicle System (IVS) establishes an emergency call to the emergency authority via the mobile network. IVS can be used for "e-call only" service or "mixed mode e-call" service. In a mixed mode e-call service, the system can be used to perform emergency e-calls as well as non-emergency subscription-based calls. However, in e-call only mode, the system can only be activated to make emergency calls, and an IVS in e-call only mode is not registered on the mobile network until the e-call is triggered. Therefore, when an e-call emergency is triggered, two actions...
