Abstract
Cellular radio system base stations (10, 12) offer various service levels and transmit control messages (14) indicating said service levels. Terminals (20) store information (22) about previous connections and, based on that information or on their own capability, produce a prediction on the service level required by the next connection. A terminal selects a cell such that the service level in the cell matches the terminal's prediction on the service level required.
Claims18
A method for a terminal to select a cell in a cellular radio system, comprising the steps of
- receiving from a multitude of base stations of a cellular radio system information about the service levels offered by said base stations,
- producing a prediction about what kind of service level will be needed for the next connection between the terminal and a base station, and
- selecting a cell in which the service level offered by the base station corresponds to the prediction produced by the terminal.
A terminal of a cellular radio system, comprising
- means for receiving control messages transmitted by base stations,
- means for selecting a cell,
- memory means,
- an arrangement for producing a prediction on the service level needed in the next connection and
- an arrangement for selecting a cell such that in the selected cell the service level offered by the base station matches said prediction.
A cellular radio system, comprising
- terminals.
- base stations offering various service levels
- at least in one base station means for transmitting control messages describing the service level of the base station in question, and
- at least in one terminal
- an arrangement for producing and storing on memory means a prediction on the service level most likely needed in the next connection between it and a base station, and
- an arrangement for selecting a cell on the basis of a comparison between
- the prediction stored on the memory means and
- the service level offered by the base station.
