According to certain embodiments, a method by a first network node operating as a Radio Access Network (RAN) node for dynamic scheduling prioritization for live uplink streaming includes receiving at least one priority level. Based on the at least one priority level, an expected quality level is determined. The expected quality level is defined as a Quality of Service (QoS) of a QoS flow being scheduled with a service quality above a minimum quality level and below a maximum quality level. A current service quality for a plurality of QoS flows is determined. Based on the combined current service quality and the expected quality level, a scheduling priority for assigning resources to a plurality of QoS flows is determined.

Dynamic prioritization for live streaming

A method of initiating a handover of a User Equipment, UE, from a first type of Radio Access Technology, RAT, to a second type of RAT, wherein said UE is attached to a core network via an Access Node, AN, comprised by a Radio Access Network, RAN, utilizing said first type of RAT, wherein said method comprises the steps of transmitting, by said UE, to said AN, measurement data relating to qualities of links between said UE and access nodes in said RAN, receiving, by said UE, an indicator from said AN, wherein said indicator informs said UE that there is a risk of losing connectivity between said UE and said Radio Access Network, initiating, by said UE, triggered by said received indicator, a handover in order to access the CN via said second type of RAT.

A network information system for determining transport conditions in a communications network. Monitoring data is acquired from a plurality of data transport nodes in a communications network. Transport conditions are determined from network information related to transport flows for network transmission of real time media flows. The network information is determined from a subset of the acquired monitoring data. The determined transport conditions are provided to at least one of a network connected device running an application involving the network transmission of real time media flows and a data transport node involved in the network transmission of real time media flows.

Handling of transport conditions

There is provided a network information system for handling network characteristics. The network information system comprises a first functional module, a second functional module, and a third functional module. The third functional module is arranged to invoke handling of network characteristics by triggering operation of the first functional module and the second functional module. An available bitrate for a media flow is estimated. Information about a permitted share of physical resources to be used during the transmission of the media flow is acquired. The estimated available bitrate for the media flow is updated. The updated estimated available bitrate is provided to a network entity associated with transmission of the media flow.

Handling of network characteristics

A method relating to a video conference connecting a first terminal to a plurality of second terminals via a switching server is disclosed. The switching server receives a plurality of uplink video streams from the first terminal via a single transport path, and the switching server sends a downlink video stream based on the uplink video streams to each of the second terminals. The method involves the steps of collecting information relating to the use of each of the second terminals and determining an order between the uplink video streams based on the information. The method further involves the steps of generating instructions for the first terminal to adjust the plurality of uplink video streams based on the order, and informing the first terminal of the instructions. A switching server and a first terminal involved in the method are also disclosed.

Operating a receiver communication device during a real time communication session including a real time media content data stream provided by another communication device may include receiving the real time media content data stream of the communication session from the other communication device wherein packets of the real time media content data stream include an identification of the real time media content data stream. A pause request may be transmitted from the receiver communication device to the other communication device with the pause request including the identification of the real time media content data stream and a pause request sequence number. After transmitting the pause request, a pause acknowledge message may be received from the other communication device with the pause acknowledge message including the identification of the real time media content data stream and the pause request sequence number. Related devices and methods are also discussed.

A communication device and method provide selective control of a level of buffering of at least one data stream. The communication device includes a jitter buffer (), a jitter buffer control unit () and a user interface (). An instruction received via an input to a user interface () indicates a jitter buffer strategy (), such as enabling a jitter buffer or setting a size of a jitter buffer, based on the user input. The control unit () sets the buffer strategy based in the instruction, and a data stream transmitted via a packet-switched network is received () and buffered for play out based on the buffer strategy ().

Method for manually optimizing jitter, delay and synch levels in audio-video transmission

A method and apparatus for establishing a requested communication session between two terminals (A, B) over a given physical channel, wherein the session requires the determination of session parameters before the session can be executed. It is determined () by means of at least one session key, whether any session parameters for a previous session between the terminals have been stored in the terminals. If so, the stored session parameters are retrieved (), such that the requested session can be executed () based on the retrieved session parameters. In this way, delays involved with the establishment of sessions requiring the determination of parameters, e.g. in multimedia calls, can be reduced.
