A method performed by a gateway node for handling application data traffic of a session between a UE and an application server in a wireless communications network is provided. Upon establishing the session, the gateway node obtains from a policy node, an identity identifying one or more rules provisioned for the UE. The identity is associated with the session and with a UP based API to be used for the session. The gateway node receives through the UP based API, a message from the UE. The message comprises the identity and a flow identifier identifying the application data traffic related to the identity. The message requests the one or more rules to be enforced by the gateway node. Upon detecting application data traffic associated with the flow identifier, the gateway node enforces the one or more rules, according to the obtained identity, for the detected application data traffic between the UE and the application server.

Method and device(s) for supporting estimation of latency over a communication path in a communication network between a data flow shaping node, providing a data flow in bursts towards a data flow target node, and a probe node. The devices(s) initiate to transmit, by the data flow shaping node, a sample burst being a burst of said bursts that differs in a predefined manner from preceding and subsequent bursts so that the data flow target node in response to the sample burst transmits a certain pattern of acknowledgement packets that differs compared to patterns of acknowledgement packets transmitted by the data flow target node in response to said preceding and subsequent bursts. The device(s) initiates to identify, by the probe node, receipt of potential acknowledgement packets according to said certain pattern.

Methods and arrangements for supporting estimation of latency over a communication path in a communication network

The present disclosure relates to techniques for shaping video data traffic in a packet switched communications transport network. In some embodiments, a device determines a cell load level associated with a base station node that is representative of a data traffic load of a cell of the base station node. The device sets, based at least on the determined cell load level associated with the base station, one or more burst transmission parameters for video data transmitted by a traffic shaping node to the base station node. The device transmits video data to the base station node using the set one or more burst transmission parameters, wherein transmitting video data occurs in one or more burst transmissions that each include a plurality of packets that include video data.

Method and device(s) for supporting estimation of latency over a communication path in a communication network between a data flow shaping node and a probe node. The communication path comprising a data flow target node configured to receive a data flow from a data flow source node via the communication path. The data flow shaping node being configured to provide the data flow in bursts towards the data flow target node. The device(s) initiate to identify a suitable burst interval being a burst interval for which the probe node receives no potential acknowledgement packets during a predefined quiescent period, associated with the suitable burst interval, that covers an end portion of the suitable burst interval and/or a begin portion of a subsequent burst interval.

The application data is transmitted via a radio link between a radio device Q and the wireless communication network. The application data are provided by one or more applications. A node of the wireless communication network provide control information, which is provided to at least one of the applications. The control information controls providing of the application data by the at least one application to the radio link.

A first network node is arranged to communicate with a second network node. The first and second network nodes are connected by a first path and a second path. The first path uses a first communications network and the second path uses a second communications network. The first network node has a first mode and a second mode of operation, such that in a first mode traffic between the first and second network nodes is transmitted over the first path and not the second path, and in a second mode traffic between the first and second network nodes is transmitted over the first path and the second path. The network node comprises a mode selector arranged to select the second mode of operation when the demanded amount of traffic between the first and second network nodes exceeds a threshold value for a period of time.

Resource usage in a multipath network

A method performed by a communication device in a network comprising mobile networks operated by mobile network operators, MNOs, is provided. The method includes signaling to a first server to discover a second server having information about a public land mobile network identifier and a network service of a MNO. The second server has a first fully qualified domain name, FQDN, pointing to a provider domain. The method further includes receiving a response including a resolution or a redirection of the FQDN; signaling to discover the information about the network service; and receiving a response from the second server including a first identification of the information about the network service of the MNO or a second identification that the network service is not available. Corresponding methods performed by a first server and a second server are also provided.

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.
