Methods, radio communication device and base station device for managing a media stream

A method, performed by a base station device, to manage a media stream to be transmitted from a media server to a radio communication device, wherein the method comprises:

• receiving, from the radio communication device, a request for a second set of media rates of a media stream that comprises a plurality of segments, which are defined by a first set of media rates and by one or more segment time periods relating to a duration of the plurality of segments, wherein the request comprises:
• information about the first set of media rates,
• a parameter relating to length of the one or more segment time periods, and
• an indication relating to a time period during which the second set of media rates is below a media stream rate for reception at the radio communication device,
• selecting a model for prediction of the media stream rate based on the indication and the parameter;
• obtaining information about radio conditions for use as input to the model;
• predicting the media stream rate based on the selected model and the information about radio conditions;
• assigning one or more of the first set of media rates to the second set of media rates based on the predicted media stream rate;
• and
• transmitting, to the radio communication device, a response indicating the second set of media rates.

A radio communication device configured to manage a media stream to be received from a media server, wherein the radio communication device is configured to:

• transmit, to the media server, a request for a first set of media rates and at least one segment time period of a media stream comprising a plurality of segments which are defined by the first set of media rates and by the at least one segment time period, the at least one segment time period relating to a duration of the plurality of segments;
• receive, from the media server, a response indicating the first set of media rates and the at least one segment time period;
• transmit, to a base station device, a request for a second set of media rates, wherein the request comprises:
• information about the first set of media rates,
• a parameter relating to length of the at least one segment time period, and
• an indication relating to a time period during which the second set of media rates is below a media stream rate for reception at the radio communication device,
• thereby enabling the base station device to predict the media stream rate, based on the indication and the parameter, and to assign one or more of the first set of media rates to the second set of media rates based on the media stream rate;
• receive, from the base station device, a response indicating the second set of media rates, and
• select a media rate out of the second set of media rates.

A base station device configured to manage a media stream to be transmitted from a media server to a radio communication device, wherein the base station device is configured to:

• information about the first set of media rates,
• a parameter relating to length of the one or more segment time periods, and
• an indication relating to a time period during which the second set of media rates is below a media stream rate for reception at the radio communication device,

• obtain information about radio conditions for use as input to the model;
• predict the media stream rate based on the selected model and the information about radio conditions;
• assign one or more of the first set of media rates to the second set of media rates based on the predicted media stream rate;
• and
• transmit, to the radio communication device, a response indicating the second set of media rates.
