Abstract
A method of cell selection in a wireless cellular network having a plurality of radio system cells involves determining a bandwidth indication for data communication through each of a serving cell and at least one neighbouring cell to the serving cell. The bandwidth indication comprises an indication of the capacity for data communication through each cell. One of the cells is then selected for packet-based communication in accordance with the determined bandwidth indications.

A method of cell selection in wireless mobile communication station operable in a wireless cellular network having a plurality of radio system cells, the method comprising the steps of:
- determining a bandwidth indication for data communication through each of a serving one of the radio system cells and at least one neighbouring cell to the serving cell, each said bandwidth indication comprising an indication of a capacity for data communication through each said cell;
- and
- selecting one of the cells for packet-based communication in accordance with the determined bandwidth indications.
A wireless mobile communication station configured for communication within a wireless cellular network having a plurality of radio system cells, the mobile station comprising:
- bandwidth determining means for determining a bandwidth indication for data communication through each of a serving one of the radio system cells and at least one neighbouring cell to the serving cell, each said bandwidth indication comprising an indication of a capacity for data communication through each said cell;
- and
- cell selecting means in communication with the bandwidth determining means for selecting one of the cells for packet-based communication in accordance with the determined bandwidth indications.
A base station subsystem for directing cell reselection within a wireless cellular network having a plurality of radio system cells, the base station subsystem comprising:
- a radio transceiver configured to provide a wireless link with a mobile station camped on one of a plurality of neighbouring radio system cells;
- a network interface configured to interface the base station subsystem with a core network of the cellular network;
- and
- a network capacity analyzer coupled to the radio transceiver and the network interface, the network capacity analyzer being configured to determine for each neighbouring cell an indication of a capacity of a wireless link between the mobile station and the base station subsystem and to initiate transmission of the capacity indications to the mobile station.
A method of directed cell selection in a wireless cellular network having a plurality of radio system cells, the method comprising the steps of:
- determining an indication of a capacity for data communication through each of a plurality of neighbouring radio system cells;
- and
- transmitting over each of the neighbouring radio system cells the capacity indications for each neighbouring cell, a mobile station camped on one of the neighbouring cells being configured to receive the transmitted capacity indications and to select one of the neighbouring cells for packet-based communication in accordance with the received capacity indications.
