Asymmetry between uplink and downlink can cause the cell with acceptable signal strence on the downlink be bad for the uplink. This may cause dropping of the call and temporary break of radio link in TETRA-style system. It is proposed to use system paging to estimate both downlink and uplink quality of the target cell before continuing the call on the selected cell.
