Abstract
A method of transmitting messages from a network node in a communication network to a first user device wherein the network node transmits to a second user device a message-waiting notification, identifying the first user device and optionally identifying a node holding the message, and in response to that notification, the second user device transmits a connection request to the first user device, said connection request being acted on by said first user device to establish a connection, optionally with the identified node, whereby said message can be transmitted to said first user device.

A method of transmitting messages from a network node in a communication network to a first user device wherein the network node transmits to a second user device a message-waiting notification, identifying the first user device and optionally identifying a node holding the message, and in response to that notification, the second user device transmits a connection request to the first user device, said connection request being acted on by said first user device to establish a connection, optionally with the identified node, whereby said message can be transmitted to said first user device.
A user terminal for communicating with a plurality of peer user terminals and a network node, said user terminal having means responsive to a message-waiting notification from said network node identifying at least one of said peer user terminals to transmit a connection request to said at least one identified peer user terminal for connection to the or another network node.
A network node in a communication network comprising means for generating packets for communicating with a plurality of user terminals using a communications protocol wherein one of said packets comprises:
- a header identifying one of said user terminals to receive said packet;
- and
- an identifier of another of said user terminals to indicate said other user terminal has a message waiting at the network node.
