Abstract: A method for an enhanced initiation and/or routing of an emergency session in a packet switched communication system includes: determining or defining—by a mobile communication device or by means of the mobile communication device—of personal communication ability information and/or personal medical condition information of a user of the mobile communication device; and initiating the emergency session by using the mobile communication device. Initiating the emergency session comprises transmitting an emergency message, via a packet switched connection of the mobile communication device, to the packet switched communication system. The personal communication ability information and/or the personal medical condition information is part of the emergency message.

Abstract: A method for the operation of wireless base stations for packet transfer radio systems having guaranteed service quality. The method includes increasing the supply ranges of packet oriented transferring radio stations, which are located outside the range of the central base stations and are supplied by wireless base stations (relay stations). In contrast to conventional wireless transfer systems, a communications service quality is guaranteed. A common time interconnected capacity assignment method is used. The capacity assignment is generated for an access point (AP) by mobile and forward terminals (MT, FMT) which can be reached directly. Individual MTs are present in the form of wireless base stations and serve as relay stations (FMTs) for the MTs outside the range of an AP. For an AP, FMTs appear as MTs. The FMT forms a partial frame structure in a part of the AP distribution capacity transfer system, which is embedded in the time frame structure dictated by the commanding central station.
