Identification of multiplexed multimedia broadcast multicast service from a central node to a UMTS evolved Node B (eNB)

摘要

The eNB segments and concatenates IP packets received from a central node, which packets may relate to more than one MBMS service multiplexed together. Multiplexing more than one service together, before segmentation and concatenation, achieves a data stream with less variant bit rate. The eNB uses the service identity information received from the central node with each IP packet to label each packet transmitted on the air interface, using the MAC information elements. The service identity in incorporated into the MAC headers of the transport blocks in order to transmit the MBMS services.
