Broadcasting or multicasting of signalling messages in a wireless network using an access node as a broker

A method comprising:

• generating, in a terminal device of a wireless network, a signaling message to be transmitted as a broadcast or multicast message to at least one other terminal device of the wireless network;
• causing transmission of the signaling message as a unicast message to an access node;
• and
• after transmitting the unicast message to the access node, receiving the signaling message from the access node as the broadcast or multicast message.

An apparatus comprising:

• at least one processor;
• and
• at least one memory including a computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to:
• generate a signaling message to be transmitted as a broadcast or multicast message to at least one terminal device of a wireless network;
• cause transmission of the signaling message as a unicast message to an access node;
• and
• after transmitting the encapsulated message to the access node, receive the signaling message from the access node as the broadcast or multicast message.

A non-transitory computer readable memory embodying at least one computer program code, the at least one computer program code executable by at least one processor to perform a method comprising:

• generating, in a terminal device of a wireless network, a signaling message to be transmitted as a broadcast or multicast message to at least one other terminal device of the wireless network;
• causing transmission of the signaling message as a unicast message to an access node;
• and
• after transmitting the unicast message to the access node, receiving the signaling message from the access node as the broadcast or multicast message.
