Abstract: Informing a number of users about an emergency or other situation of public interest is accomplished using a broadcast service. A specific identifier is used in a paging message for activating broadcast service in terminals. A terminal checks a received paging message with regard to the presence of the specific identifier and when detecting the specific identifier, switches to a broadcast mode for receiving broadcast content. The received broadcast emergency content is notified and/or displayed to the users of the terminals.

Abstract: In a method of selecting a communication network and connecting a mobile station into a communication network in a coverage area of which it is located, a mobile station is temporarily connected to a network unit of a first communication network, and sends a request relating to at least one second communication network to be used for communication via the network unit from the mobile station to a further network unit. After verifying the request by the farther network unit at least one response message containing at least one item of information is sent to the mobile station. The mobile station connects to a communication network depending on the at least one item of information received.

Abstract: A method and system for configuring a radio interface between a mobile station and a base station in a time-division multiplex mobile radio system for packet data transmission, wherein time slots for signalling are allocated by the base station to the mobile stations in accordance with a sequence which can be predetermined, independent of packet data transmission. The time for configuration of the radio interface also can be reduced by a plurality of time slots for signalling being combined to form a signalling block, or the signalling to a plurality of mobile stations being carried out within one time slot. This signalling is used to define and set the timing advance.

Abstract: For a communication system (e.g. UMTS with CDMA radio interface), the invention draws a distinction between services with high and low data rate dynamics and uses a matched type of signaling for the transport formats currently being used. The data rate of the data for a service can fluctuate greatly and/or rapidly over time (high dynamics), or may fluctuate only a little and/or slowly (low dynamics). The data for the services are transmitted via a common physical channel, with in-band signaling being used for signaling the transport format for the services with high data rate dynamics, and with signaling in a separate channel being used for the services with low data rate dynamics.

Abstract: A method and system for configuring a radio interface between a mobile station and a base station in a time-division multiplex mobile radio system for packet data transmission, wherein time slots for signalling in the uplink direction are allocated by a base station to the mobile stations in accordance with a sequence which can be predetermined independently of packet data transmission. The fixed allocation of a time slot for signalling, in addition to mobile stations to which no physical channel is currently allocated, allows the base station to carry out continuous measurement relating to the radio interface. Thus, when packet data transmission resumes, immediately valid measurements are available for configuration of the radio interface.

Abstract: For configuration of a radio interface between a mobile station and a base station in a time-division multiplex mobile radio system for packet data transmission, time slots for signaling are allocated by a base station to the mobile stations in accordance with a sequence that can be predetermined in the downlink direction, and the time for configuration of the radio interface can be reduced by a plurality of time slots being combined to form a signaling block for a plurality of mobile stations.

Abstract: In order to call mobile'stations, mobile stations are, according to the invention, allocated to time slots for calling on the basis of subscriber-specific profiles. The number of time slots allocated for calling within a macroframe can be set individually for the mobile, stations. The requirement for time slots allocated for calling is thus covered individually for each mobile station. For time-critical applications, shorter delay times can be achieved using the method according to the invention.

Abstract: A method and system for configuring a radio interface between a mobile station and a base station of a time-division multiplex mobile radio telephone system for a packet data transmission, wherein, the mobile stations are additionally identified with brief identifiers and time slots for signaling for the upstream direction are allocated to the mobile stations. The allocation of one or more time slots for signaling for the upstream direction occurs according to a prescribable sequence, wherein the allocation occurs with indicator messages that contain abbreviated identifiers and time slot designations. The allocation is thus independent of a sequence of the packets data transmission from or to the mobile station.
