Abstract: There is provided an apparatus comprising receiving, from a primary mission critical system, one or more user profile configuration documents comprising information identifying one or more partner mission critical systems to which the user equipment can migrate, and a respective one or more user equipment initial configurations associated with each of the one or more partner mission critical systems; selecting a partner mission critical system to migrate to from among the one or more partner mission critical systems; selecting, from the received one or more user profile configuration documents, a user profile configuration document for use in the migration; and based on the selected user profile configuration document, performing migration to the selected partner mission critical system.

Abstract: The present application discloses a system of at least a network element and at least a terminal. The system constituents are configured to provide assistance by the terminal to the network element in terms of access domain selection for at least one of the media channel and the session control channel of an incoming call to the terminal. In this regard, the terminal acquires information about the capabilities of an access network in which the terminal is camping. Upon receiving, at the terminal, an invitation to participate in a call, the terminal analyzes the acquired information about the capabilities of the access network, and optionally or additionally of the IMS network. The terminal responds to the invitation, based on the result of the analyzing, with an indication that indicates a respective access domain to be used for at least one of the media channel and the session control channel of the incoming call.

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: For signalling for configuration of a radio interface for packet data transmission (GPRS), time slots for signalling are allocated by a base station to the mobile stations in accordance with a sequence which can be predetermined in the downlink direction. The time for configuration of the radio interface can also be reduced by a plurality of time slots being combined to form a signalling block for a plurality of mobile stations.

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.
