Abstract: A method and a device proxy for handling radio communication of content data from a data source to be played out on a media player of a wireless device in a wireless network. When detecting that a potential data class is available, the device proxy fetches segments of the content data from the data source over a potential data bearer dedicated for data of said potential data class. The potential data bearer is dedicated for data of the potential data class, which is less sensitive to delay than data of other data classes. The potential data bearer is also less costly to use compared to other data bearer(s). The fetched segments of content data are stored by the device proxy in an intermediate buffer, and the segments of content data are delivered from the intermediate buffer when requested by the media player.

Abstract: A network node includes control plane functionality for managing a session of a user equipment (UE) which is anchored at a User Plane Function (UPF) anchor for communicating traffic between the UE and a data network. The node operates to obtain, from an Access and Mobility Management Function (AMF), a session context request responsive to a handover indication indicating a handover of the session from a Fifth Generation System (5GS) to an Evolved Packet System (EPS).

Based on the identifying, the node obtains uplink tunnel information of the UL-CL UPF instead of the UPF anchor for establishing at least one bearer for the session and sends to the AMF a session context response including the uplink tunnel information of the UL-CL UPF.
