Method for transmitting data packets based on message type

A method for communicating information between a source and at least one destination, the method comprising the steps of:

• at the source;
• providing information to be transmitted, which information comprises one message type of a plurality of message types as indicated by a TOP session header included in the information;
• formatting the information into a plurality of data packets;
• automatically selecting as between a circuit switched network and a packet switched network based on the one message type indicated by the TCP session header, wherein the circuit switched network is selected when a long type is indicated by the one message type, and wherein the packet switched network is selected when a short type is indicated by the one message type;
• when the circuit switched network is selected, establishing a circuit switched channel and transmitting the plurality of data packets via the circuit switched channel;
• when the packet switched network is selected, establishing a packet switched channel and transmitting the plurality of data packets via the packet switched channel;
• at the at least one destination;
• determining that the plurality of data packets is being transmitted as between the circuit switched network and the packet switched network;
• when the plurality of data packets is transmitted over the circuit switched network, receiving the plurality of data packets via the circuit switched channel;
• and
• when the plurality of data packets is transmitted over the packet switched network, receiving the plurality of data packets via the packet switched channel.
