Summary:The invention relates to a method of managing a suspend state of a packet-switched service in a system which comprises a terminal (MS) and another peer (12), there being a packet-switched connection between the terminal and the other peer over which the terminal and the other peer transmit packets to each other. The terminal (MS) is able to use only either a circuit-switched service or a packet-switched service at the same time. When the terminal (MS) switches to the suspend state in the packet-switched service to use a circuit-switched service, a predetermined first packet (31) is transmitted from the terminal (MS) to the other peer (12) to prevent transmission of packets from the other peer (12) to said terminal (MS) during the suspend state. The invention also relates to a terminal and software. In a preferred embodiment, the first packet is a TCP acknowledge message for the latest correctly received packet including the value 0 as advertised window parameter.
