Signaling and management of broadcast-multicast waveform embedded in a unicast waveform
Embodiments describe overlaying a broadcast multicast channel on top of a unicast network. Messages can be generated by protocols in a broadcast/multicast (BCMC) stack and tunneled through an IRTP of a serving access node. These messages can be transmitted on a BCMC channel and/or a unicast channel. Other messages can be generated by protocols in a unicast stack and tunneled to a B-IRTP of a BCMC Access node and transmitted on a BCMC channel to an access terminal.
1. A method for receiving a tunneled out of band signaling of a broadcast-multicast waveform over a unicast waveform, comprising:
receiving a message over a unicast waveform;
processing the message through a unicast stack responsive to receiving the message;

outputting the message to a user after routing the message to the BCMC stack.
2. The method of claim 1 , further comprising:
tunneling the message though an Inter-Route Tunneling Protocol (IRTP) before routing the message to the BCMC stack.
