Abstract:
1. Cell selection device for a piece of wireless communication equipment arranged to establish radio communications with a radio communication network comprising radio communication cells, and to receive data representative of a cell environment and of service capabilities of each cell of said environment from said network, characterized in that it comprises a control means arranged to access the data received by said equipment and representative of the cell environment and the corresponding cell service capabilities, when said equipment (MS) needs to access a chosen network service, to determine whether there is at least one cell in said environment that allows to access said network service, and orders said equipment either to pursue or to establish a radio communication with said network via a selected one of these determined cells if said selected cell allows at least one chosen radio parameter criterion to be satisfied, wherein said radio parameter comprises re-selection parameters C1 and C2, and in that said control means is arranged to compare a value C2s of the parameter C2 of the cell in which said mobile phone is located to each corresponding value C2ni of each neighboring cells offering said chosen network service, and then, if said value C2s exceeds each value C2ni added to a chosen threshold and if the value C1s of the parameter C1 of the cell in which said mobile phone is located exceeds 0, to select the neighboring cell that offers the best value C2ni.
