First Claim
1. A method in a telecommunication network for a first multimedia terminal in a group to determine multimedia capabilities supported by a group server and a plurality of other multimedia terminals in the group, said method comprising the steps of:
- receiving in the group server during an ongoing multimedia session, a first service enquiry message from the first multimedia terminal in the group, the first service enquiry message including a session identity for the ongoing multimedia session;
sending a second service enquiry message from the group server to the other multimedia terminals in the group;
receiving in the group server as a response to the second service enquiry message, a first service response message from each of the other multimedia terminals to which the second service enquiry message was sent, each of the first service response messages including capabilities of one of the other multimedia terminals;
analyzing by the group server, the received capabilities in the first service response messages to determine a common set of capabilities and to allow or forbid certain of the capabilities in the common set based on local policy in the group server and a user profile for a user of the first multimedia terminal; and
sending as a response to the first service enquiry message, a second service response message from the group server to the first multimedia terminal, said second service response message including an allowed common set of capabilities.

Abstract
A system and method for handling multimedia conference calls in a telecommunication network. To determine the capabilities of the other terminals in a group, a first terminal sends a query message to a group server. The group server sends further query messages to the other terminals and collects their responses containing their capabilities. The group server analyzes the capabilities to determine a common set of capabilities. The group server then sends the common set of capabilities in a response to the first terminal.
