Abstract:
1. A cell selection system for selecting a cell to be used for communications by a mobile terminal in a network, the cell selection system comprising: a first cell using a first communication protocol; a plurality of second cells, the plurality of second cells' coverage is under the first cell's coverage and uses a second communication protocol that is different for the first communication protocol; and a mobile terminal supporting communications using the first and second communication protocols in the first and second cells in the network, wherein broadcast information having cell selection information is transmitted in the first cell, the cell selection information including cell change judgment parameters having a number of patterns that is less than a number of the second cells, and the mobile terminal receives the broadcast information of the first cell and broadcast information of one of the second cells; reads the cell selection information from the broadcast information of the first cell; determines, from the number of patterns of parameters included in the read cell selection information, a parameter to be used for making a judgment on cell selection of a second cell based on the broadcast information of the second cell; and judges based on the determined parameter whether to change a communication connection of the mobile terminal from the first cell to the second cell.
