Abstract

In existing mobile communication systems like GSM (Global System for Mobile Communications) or UMTS (Universal Mobile Telecommunication System) emergency calls are defined. The system and/or the access technology selection have to result in a call handling that satisfies the regulatory requirements and the user expectations. However, today emergency calls cover the voice connection only, whereas additional, valuable information from the mobile is not used. Additionally, discussions in the regulatory environments discuss the possibility to require the inclusion of additional information in the near future. The idea is to provide additional information available at the mobile station along with the establishment of an emergency call. The main idea of this approach is to consider a small data component (SMS (Short Message Service) or EMS (Enhanced Messaging Service) messages), beyond voice as part of an "enhanced emergency call" and to ensure that they are handled as one single "enhanced emergency call" by the networks it traverses. The phone autonomously sends the small data component in case of an emergency call (without any action by the caller). Examples of small data components beyond voice are the existing SMS and EMS services. An enhanced emergency call should be considered as a single unique "service" by the network, i.e. the voice call and the additional SMS/EMS component are appropriately given the maximal preference that ensure that the enhanced emergency call is routed appropriately inside the networks and that the components do not suffer unnecessary delays and receive commonly at the emergency call center. This may include giving the enhanced emergency call SMS/EMS component more preference than other SMS/EMS messages.

Enriched Emergency Calls in Mobile Communication Systems by Use of Additional SMS or EMS Messages

In existing mobile communication systems like GSM (Global System for Mobile Communications) or UMTS (Universal Mobile Telecommunication System) emergency calls are defined. The system and/or the access technology selection have to result in a call handling that satisfies the regulatory requirements and the user expectations. However, today emergency calls cover the voice connection only, whereas additional, valuable information from the mobile is not used. Additionally, discussions in the regulatory environments discuss the possibility to require the inclusion of additional information in the near future.

The idea is to provide additional information available at the mobile station along with the establishment of an emergency call.

The main idea of this approach is to consider a small data component (SMS (Short Message Service) or EMS (Enhanced Messaging Service) messages), beyond voice as part of an "enhanced emergency call" and to ensure that they are handled as one single "enhanced emergency call" by the networks it traverses. The phone autonomously sends the small data component in case of an emergency call (without any action by the caller).

This may include giving the enhanced emergency call SMS/EMS component more preference than other SMS/EMS messages.

In order to identify the additional components as being added to the enhanced emergency "call" and to speed up the transfer of the SMS/EMS messages, the SMS/EMS messages can be transferred during the circuit switched setup procedure or during an ongoing emergency voice call either parallel the voice stream by help of RR (Radio Resource) s...
