First Claim
1. A messaging system for communicating a message between a first communications unit having a first messaging entity and a second communications unit having a second messaging entity, each messaging entity having a messaging call control means for establishing a messaging communications link with the other messaging entity;
- and a messaging means for, once the messaging communications link has been established, exchanging messaging information with the said other messaging entity wherein the messaging entity receives data from and transmits data to the application layer of the communication protocol such that each messaging entity comprises a virtual layer between an application layer and a network layer of a communication protocol.

11. A messaging method for communicating a message between a first communications unit and a second communications unit, the first communications unit having an application layer, a messaging entity and a network layer, the method comprising,the steps of:
-
transmitting a signal from the application layer to the network layer as a means of establishing a call;
exchanging messaging information between the application layer and the network layer by way of the messaging entity to communicate the message; and
transmitting a signal from the application layer to the network layer as a means of disconnecting the call, wherein the messaging entity constitutes a virtual layer between the application layer and the network layer of the communication protocol.
