Abstract: The embodiments herein relate to a method in a network node (101) for handling states associated with a wireless device (105) in a communications network (100). The network node (101) is connected to the wireless device (105) over a communications link (110). The communications link (110) is in a current state. The network node (101) receives, from the wireless device (105) information related to a data activity in the wireless device (105). The received information comprises at least information other than a current amount of data associated with the data activity. Based on the received information, the network node (101) determines a change associated with the current state.

Abstract: An important objective for third generation mobile communications systems is to provide IP services, and a very important part of these services will be the conversational voice. The conversational voice service includes three distinct information flows: session control, the voice media, and the media control messages. In a preferred embodiment, based on the specific characteristics for each information flow, each information flow is allocated its own bearer with a Quality of Service (QOS) tailored to its particular characteristics. In a second embodiment, the session control and media control messages are supported with a single bearer with a QoS that suits both types of control messages. Both embodiments provide an IP conversational voice service with increased radio resource efficiency and QoS.
