Presence server, session control server, and packet relay system
First Claim
1. A presence server that can be connected to a session control server for communication control between plural terminals and manages the status information of the plural terminals, comprising:
- a line interface;
a controller that extracts the terminal type information of an originator terminal of a packet received via the line interface from the head information of the received packet; and
a storage that storing the extracted terminal type information and session status information between a partner terminal that communicates with the originator terminal and the originator terminal in a state in which their information is related, wherein;
the line interface transmits the terminal type information of the originator terminal to the partner terminal.

Abstract
The object of the invention is to make communication between users smoother utilizing terminal type information. To achieve the object, a terminal type is specified based upon information in login and information acquired by adding the information to presence information is notified. Besides, terminals of the same type are connected by an SIP server. The selection of the communication means of voice communications and a character chat when communication is started and the specification of a calling terminal at a partner terminal are enabled by adding terminal information to presence information and grasping mutual owned terminals. Detailed status can be grasped based upon presence information of the same name by grasping presence information and terminal information. Further, in the case of a terminal not provided with a presence function, an SIP server also identifies terminal type information by deputy and can also specify a calling terminal.
