Direct communication and localisation of mobile end equipment and emergency handling
First Claim
1. A mobile communication network system (1) comprising a plurality of mobile stations and a backbone communication network (2) with network antennas (TRX 1) for establishing communication (3) between a first mobile station (MS 1) of said plurality of mobile stations and said backbone communication network (2), characterized in that at least one direct communication channel is provided by said backbone communication network (2), said direct communication channel can be used by said first mobile station (MS 1) for broadcasting data messages, within near vicinity and to other mobile devices, which comprise means for estimating distance and direction to the said first mobile station, in particular for evaluating signal strength and other properties of the emergency signal where different emergency signals are provided differing in amplitude, frequency and pattern and where these emergency signals can be received by other mobile stations (MS2) or by network antennas (TRX1) or by special localization equipments (MSTRACK 5,6,7) in such a way that the signal can be used for localizing the said first mobile station (MS1).

Abstract
In a mobile network at least one direct communication channel between mobile stations is provided. The direct communication channel is used by a mobile station (MS 1) for broadcasting periodical emergency data messages, within near vicinity and to other mobile devices, which comprise means for estimating distance and/or direction to the this mobile station. In particular, for evaluating signal strength and/or other properties of the emergency signal where different emergency signals are provided differing in amplitude, frequency and/or pattern and where these emergency signals can be received by other mobile stations (MS2) or by network antennas (TRX1) or by special localization equipments (MSTRACK, 5,6,7) in such a way that the signal is used for localizing the first mobile station (MS1) to a high precision.
