1. A method for radio bearer mapping in a wireless network, comprising:
determining, by a data transmission network node, a data transmission flow having a predefined Quality of Service (QOS) profile containing multicast/broadcast service data to a plurality of user equipments;
mapping, by the data transmission network node, the data transmission flow to a first radio bearer for transmitting the multicast/broadcast service data to a first set of user equipments among the plurality of user equipments;
mapping, by the data transmission network node, the data transmission flow to a second radio bearer independent of the first radio bearer for transmitting the multicast/broadcast service data to a second set of user equipments among the plurality of user equipments; and
configuring the data transmission network node to transmit the multicast/broadcast service data independently via the at least the first radio bearers and the second radio bearer each carrying the data transmission flow.
