1. A method for rejecting a session request initiated via a session establishment protocol operable via a network, comprising:
- receiving at a first network terminal a session initiation request sent from a second network terminal via the session establishment protocol;
forming a rejection message of the session establishment protocol based on a presence state of the first network terminal; and
sending the rejection message via the session establishment protocol targeted for the second network terminal.

Abstract
Rejecting a session request initiated via a session establishment protocol involves receiving, at a first network terminal, a session initiation request sent from a second network terminal via the session establishment protocol. A rejection message of the session establishment protocol is formed based on a presence state of the first network terminal. The rejection message is sent via the session establishment protocol targeted for the second network terminal.

9. A data terminal comprising:
-
a network interface configured to communicate via a network;
a memory storing a message module; and
a processor coupled to the network interface and the memory, the processor operable by the message module to, receive via the network interface a session establishment request of session establishment protocol;
determine a presence state of the data terminal;
form a rejection message of the session establishment protocol based on the presence state; and
send the rejection message targeted for an originator of the session establishment request via the network interface. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A system comprising:
-
a network providing communications via a session establishment protocol;
a first terminal capable of establishing multimedia data sessions via the network using the session establishment protocol; and
a second terminal comprising, a network interface capable of communicating via the network;
a processor coupled to the network interface, the processor operable to, receive via the network interface a session establishment request from the first terminal;
determine a presence state of the second terminal;
form a rejection message of the session establishment protocol based on the presence state; and
send the rejection message to the first terminal via the network interface; and
wherein the first terminal is configured to receive the rejection message and display a reason descriptor text based on the rejection message to a user of the first terminal. - View Dependent Claims (18, 19, 20, 21, 22)
