METHOD AND DEVICE FOR PROVIDING POINT-TO-MULTIPOINT SERVICES |
摘要 |
<p>The invention relates to a point-to-multipoint service in a communications network (10) sends a point-to-multipoint notification message (S1) that comprises information on a content transmission (S2). One or more terminals (11-14) reply to the point-to-multipoint notification message or the content transmission with a response message (S3). The network checks from which terminals it received a response message (S4) and compares these terminals with a group of terminals associated with the content transmission (S5). If there are terminals in the group of terminals that did not send a response message, the network will send a point-to-point notification message to them (S7). The point to-point message can be sent in a store-and-forward manner so that terminals temporarily not being able to communicate with the network can receive the message.</p> |
