Megaco protocol with user termination
First Claim
1. A method of providing a mechanism to transfer user-related information from a media gateway controller to a media gateway transferring media streams to and from a user in a telecommunications system, the method comprising:
- creating in the media gateway a user termination for the user'"'"'s user-related information, the user termination being non-call-specific and associated with the user; and
directing the media streams via the user termination.

Abstract
Megaco is a device control protocol defining a general framework for physically decomposed media gateway, where the intelligence of the gateway is in a master node called the media gateway controller and the actual switching and media transfer is performed in one or more slave nodes called the media gateway(s). In order to enable to transfer user-related information from the media gateway controller to the media gateway a user termination for the user'"'"'s user-related information is created in the media gateway, the user termination being non-call-specific and associated with the user; and the media streams to and from the user are directed via the user termination.

11. A method of applying at least one instruction to media streams transferred to a user in a media gateway via which the media streams are transferred in a telecommunications system further comprising a media gateway controller controlling the media gateway, the method comprising:
-
creating in the media gateway a user termination for the user'"'"'s user-related information, the user termination being non-call-specific and associated with the user;
receiving in the media gateway at least one parameter with its value as the user'"'"'s user-related information;
storing the parameter and its value to the user termination;
directing the media streams to the user via the user termination; and
applying the stored parameter according to its value to the media streams directed to the user.

12. A method of applying at least one instruction to media streams transferred from a user in a media gateway via which the media streams are transferred in a telecommunications system further comprising a media gateway controller controlling the media gateway, the method comprising:
-
creating in the media gateway a user termination for the user'"'"'s user-related information, the user termination being non-call-specific and associated with the user;
receiving in the media gateway at least one parameter with its value as the user'"'"'s user-related information;
storing the parameter and its value to the user termination;
directing the media streams from the user via the user termination; and
applying the stored parameter according to its value to the media streams originated from the user.

13. A method of filtering media streams targeted at a user in a telecommunications system comprising a media gateway transferring the media streams to the user and a media gateway controller controlling the media gateway, the method comprising:
-
receiving in the media gateway a message from the media gateway controller, the message indicating that a user termination is to be created for the user'"'"'s filtering information, the user termination being non-call-specific and associated with the user;
creating in response to the message the user termination;
receiving in the media gateway at least one parameter with its value as the user'"'"'s filtering information;
storing the parameter with its value to the user termination;
directing the media streams to the user via the user termination; and
filtering the media streams according to the parameter and its value.
