Abstract
It is presented a method for enabling transmission of streaming content in a point to multipoint delivery. The method is performed in a radio network node of a cellular network. The method comprises the steps of: receiving a donor indication message from a wireless device in response to the wireless device receiving a donor command from an application server, the donor indication message indicating that the wireless device requests to be a donor device; setting up a point to multipoint delivery session; obtaining downlink data of streaming content destined for the donor device in a unicast delivery; transmitting the downlink data in a unicast delivery to the donor device; and transmitting a copy of the downlink data using the point to multipoint session, such that the downlink data can be received by a plurality of wireless devices being recipient devices.
