Claim Text:
1. A method, in a PTM transmission control node, for scheduling a point-to-multipoint (PTM) transmission of content data, provided by a content provider node, to a plurality of mobile terminals in a PTM-enabled network, comprising: receiving an indication of a delivery time at which the content data is to be receivable by the plurality of mobile terminals on an air interface of the PTM-enabled network; obtaining one or more system delay parameters indicating one or more system delays, including indicating transmission delays between the PTM transmission control node and a radio access node to be used in the PTM transmission of the content data; determining a transmission start time for starting transmission of the content data from the PTM transmission control node to the radio access node, to account for the transmission delays and thereby enabling the radio access node to have the content data receivable on the air interface at the delivery time; and transmitting the content data towards the radio access node at the transmission start time.
