<p>A dual mode communication system, with user equipment (1) selectively connectable to a plurality of communication systems, for switching communication systems to which the user equipment (1) should be connected, detects that the remaining battery level fell below a first threshold in the user equipment (1) communicating over the W-CDMA system (100). In the system it is determined whether or not the user equipment (1) can communicate using the GSM system (200), which can be operated with lower power consumption than the W-CDMA system (100). When it is determined that communication can be established with the GSM system (200), the system switches from a connection between the user equipment (1) and the W-CDMA system (100) to a connection between the user equipment (1) and the GSM system (200) without interrupting the communication over the W-CDMA (100).</p> |
