A SC informs a communication service (CS) node (e.g., GCS AS) of a data transfer start time for the bearer (i.e., the user plane ready time for the bearer). Additionally, in some embodiments, the SC informs the communication service node (e.g., GCS AS) as to a data transfer stop time for the bearer. This provides a distinct advantage because the CS node will now have information as to when it should start (and stop) data delivery, thereby leading to a higher quality of experience (QoE) of MBMS delivery.

Providing to a communication service node user plane timing information for an MBMS bearer

A network node initiates a MBMS session providing a multimedia service through a RAN to UEs using a FEC operation providing an initial FEC level, where the multimedia service is concurrently provided through unicast sessions. Feedback reports received from the UEs identify UEs consuming the multimedia service through the MBMS session and identify UEs consuming the multimedia service through the unicast sessions. A ratio is determined of a number of the UEs identified as consuming the multimedia service through the MBMS session to a number of the UEs identified as consuming the multimedia service through the unicast sessions. Responsive to determining that the ratio is less than a target ratio, the FEC level provided by the FEC operation is increased. Responsive to determining that the ratio is greater than the target ratio by a defined margin value, the FEC level provided by the FEC operation is decreased.

Controlling forward error correction and modulation coding scheme for multicast broadcast multimedia services

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.
