17. A method for generating a message comprising:

determining a type of an information indicated by a first message, wherein the first message is formed in accordance with a first transmission protocol;

selecting a type of message from a plurality of existing types of messages according to a second transmission protocol based on the determined type of information; and

generating a second message of the selected type according to the second transmission protocol indicating the information, wherein the second message includes an indicator of the first transmission protocol, and wherein the indicator of the first transmission protocol includes an event package indicator.

18. The method according to claim 17 , wherein the second message is a Session Initiation Protocol message, and the indicator of the first transmission protocol includes a content type indicator.

19. One or more non-transitory computer readable media having instructions thereon that, in response to execution by one or more processing devices of a communication device, cause the communication device to:

determine a type of an information indicated by a first message, wherein the first message is formed in accordance with a first transmission protocol;

select a type of message from a plurality of existing types of messages according to a second transmission protocol based on the determined type of information; and

generate a second message of the selected type according to the second transmission protocol indicating the information, wherein the second message includes an indicator of the first transmission protocol, and wherein the indicator of the first transmission protocol includes an event package indicator.

20. The one or more non-transitory computer readable media according to claim 19 , wherein the type of information is one of information indicating a request, information indicating a positive response to a request, and information indicating a negative response to a request.

21. The one or more non-transitory computer readable media according to claim 19 , wherein the indicator indicates a type of message body that the communication device requests to receive in response to the second message.
