Communication service unit and connection sequence operating method
First Claim
1. A communication service method, comprising:
- establishing a communication link between a first terminal supporting a first communication protocol and a communication service unit configured to convert a received first communication message, sent by the first terminal and complying with the first communication protocol, to a second communication message complying with a second communication protocol for transmitting the second communication message to a second terminal supporting the second communication protocol;
obtaining at the communication service unit terminal information related to the first terminal from the first terminal through the communication link between the first terminal and the communication service unit, the terminal information to be used for executing a sequence for connecting the first terminal to the second terminal; and
recording the terminal information of the first terminal obtained through the communication link in a database accessible by the communication service unit.

Abstract
Communication is performed without paying attention to the fact that the communication is executed between multimedia terminals having communication procedures differing from each other.
A terminal 2 starts a communication procedure that is necessary to establish a communication path to a communication service unit 1, in order to execute communication with a multimedia terminal 3; when a communication protocol conversion unit 7 receives communication start request from the terminal 2, the communication service unit executes identification process of a calling terminal based on the identification number, which exists in communication start request, for determining the multimedia terminal 2, and inquires a terminal information managing unit 9 of the calling terminal. The terminal information managing unit 9 retrieves terminal information related to the calling terminal based on a terminal information request, and informs of the retrieved terminal information to the communication protocol conversion unit 7. The communication protocol conversion unit 7 informs of the communication start request to the terminal 3 when the transmitting the terminal information of the terminal 2 is obtained, and continues a relay process in communication procedure, which is necessary for following establishment of a communication path.

9. A communication service method, comprising:
-
establishing a communication link between a first terminal supporting a first communication protocol and a communication service unit configured to convert a received first communication message, sent by the first terminal and complying with the first communication protocol, to a second communication message complying with a second communication protocol for transmitting the second communication message to a second terminal supporting the second communication protocol; obtaining at the communication service unit terminal information related to the first terminal the terminal information including at least one of an encoding-method classification for media of the first terminal to be applied during a multimedia communication and unique information for encoding-method classification for media of the first terminal from the first terminal through the communication between the first terminal and the communication service unit; and converting at the communication service unit the received first communication message, sent by the first terminal and complying with the first communication protocol to the second communication message complying with the second communication protocol based on the obtained terminal information related to the first terminal. - View Dependent Claims (10)
