Abstract:
A method in data transmission between a wireless communication device (MS) and a packet network (PLMN1, PLMN2), in which data transmission between the wireless communication device (MS) and the packet network (PLMN1, PLMN2) is controlled with at least one packet switching controller (SGSN), in which method a group of connection states is determined, from said connection states one at a time is selected, and the selected connection state is set to the wireless communication device (MS) and to the packet switching controller (SGSN), and in which method said connection states are defined to be:a ready state (303), in which packets are transmissible in an activated data transmission connection, a standby state (302), in which packets to be transmitted or received are waited, and an idle state (301), in which the data transmission connection is deactivated, characterized in that an extended ready state (304) is also determined as a connection state, to which a transition from the ready state (303) is conducted and in which data transmission connection packets to be transmitted or received are waited for.
