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.

Access domain selection in a terminal

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.

Method and system for configuring radio interface in a communication system

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.
