Page-mode messaging

1. A method, comprising:

sending, using a terminal, a page-mode message using a session-mode messaging mechanism, with an indication indicating that a session-mode is for the page-mode message, in response to a page-mode message size exceeding a predetermined limit;

applying, using the terminal, a session description protocol to initiate a session in the session-mode messaging mechanism; and

adding, using the terminal, the indication to a header of a session initiation message.

2. A method of claim 1 , further comprising:

creating, using the terminal, a session for sending the page-mode message; and

terminating, using the terminal, the session in response to the page-mode message having been sent.

3. A method of claim 1 , further comprising:

creating, using the terminal, a session for sending the page-mode message;

receiving, using the terminal, information that the page-mode message have been received; and

terminating, using the terminal, the session in response to the page-mode message having been received.

4. A method of claim 1 , wherein the adding comprises adding the indication in an m-line in the header.

5. A method of claim 1 , wherein the adding comprises adding the indication comprising a parameter indicating an actual size of the page-mode message.

6. A method of claim 1 , wherein the adding comprises adding the indication comprising an m-line indication and a parameter indicating an actual size of the page-mode message.

7. An apparatus, comprising:

at least one processor; and

memory including computer program code,

the memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to

send a message using a session-mode messaging mechanism, with an indication indicating that the message is a page-mode message, in response to a page-mode message size exceeding a predetermined limit,

apply, using the terminal, a session description protocol to initiate a session in the session-mode messaging mechanism, and

add, using the terminal, the indication to a header of a session initiation message.

8. An apparatus of claim 7 , wherein the memory and the computer program code are further configured to, with the at least one processor, cause the apparatus at least to send the page-mode message in response to a user command.

9. An apparatus, comprising:

at least one processor; and

memory including computer program code,

the memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to

detect an indication in a header of a session initiation message that a session-mode messaging mechanism is used for a page-mode message, and

in response to the indication, treat a received session-mode message as the page-mode message,

wherein the page-mode message is received in response to a page-mode message size exceeding a predetermined limit.

10. An apparatus of claim 9 , wherein the memory and the computer program code are further configured to, with the at least one processor, cause the apparatus at least to store the received page-mode message in response to the reception.

11. An apparatus of claim 9 , wherein the memory and the computer program code are further configured to, with the at least one processor, cause the apparatus at least to notify a user of the page-mode message.

12. An apparatus of claim 9 , wherein the memory and the computer program code are further configured to, with the at least one processor, cause the apparatus at least to check, in response to said indication, a size of the page-mode message, and to decide continuation or termination of the session-mode mechanism based on the size of the page-mode message.

13. An apparatus of claim 9 , wherein the memory and the computer program code are further configured to, with the at least one processor, cause the apparatus at least to check, in response to said indication, a size of the page-mode message, to request from a user further instructions relating to continuation or termination of the session-mode mechanism, and to show the size of the page-mode message to the user.

14. An apparatus of claim 9 , wherein the memory and the computer program code are further configured to, with the at least one processor, cause the apparatus at least to continue the session-mode mechanism by forwarding a session request relating to said page-mode message.

15. A server apparatus, comprising:

at least one processor; and

memory including computer program code,

the memory and the computer program code configured to, with the at least one processor, cause the server apparatus at least to

detect an indication in a header of a session initiation message that a session-mode messaging mechanism is used for a page-mode message,

in response to the indication, assume itself to be an end-point of the session-mode messaging mechanism, and

in response to the indication, define a message received via the session-mode messaging mechanism as the page-mode message,

wherein the page-mode message is received in response to a page-mode message size exceeding a predetermined limit.

16. A method comprising:

receiving, using a transceiver, a session-mode message with an indication in the header of the session-mode message indicating that a session-mode is for a page-mode message; and

in response to said indication, treating, using a user terminal, the received session-mode message as the page-mode message,

wherein the page-mode message is received in response to a page-mode message size exceeding a predetermined limit.

17. A non-transitory computer readable storage medium embodying program instructions, wherein execution of said computer program instructions causes a device to:

send a page-mode message using a session-mode messaging mechanism, with an indication indicating that a session-mode is for the page-mode message, in response to a page-mode message size exceeding a predetermined limit,

apply, using the terminal, a session description protocol to initiate a session in the session-mode messaging mechanism, and

add, using the terminal, the indication to a header of a session initiation message.

18. A non-transitory computer readable storage medium embodying program instructions, wherein execution of said computer program instructions causes a device to:

treat, in response to a session-mode message being received with an indication in a header of the session-mode message indicating that the session-mode is for a page-mode message, the received session-mode message as the page-mode message,

wherein the page-mode message is received in response to a page-mode message size exceeding a predetermined limit.

19. An apparatus of claim 7 , wherein the apparatus is a user terminal and the memory and the computer program code are further configured to, with the at least one processor, cause the user terminal to use a session description protocol to initiate a session in the session-mode messaging mechanism; and to add the indication to an m-line in a header of a session initiation message.
