Method and system for controlling a real-time communications service
First Claim
1. A method of controlling a real-time media session, comprising:
- sending first signaling from first user equipment via a serving access network of the first user equipment to a first media communication server in response to a user'"'"'s action during an established real-time media session;
sending second signaling from the first media communication server towards the first user equipment;
sending third signaling from the first media communication server towards second user equipment; and
sending, immediately after one of the first, the second and the third signaling, dummy media traffic from the first media communication server towards the first and second user equipment, in order to trigger a dedicated-channel setup for at least one of the first and second user equipment in their respective serving access networks prior to beginning an actual user media stream from the first user equipment.

Abstract
A real-time media session is established between user equipment and a media communication server via a serving access network. According to the Invention, dummy data (e.g. a dummy message) is sent in order to maintain a dedicated channel during the inactive periods of a real-time media session or to trigger an early setup of a dedicated channel in the access network. In this manner, user equipment logged on to a real-time media (e.g. PoC) session are prevented from going to a radio resource idle state, thus avoiding potential long extra delays during real-time media (e.g. PoC) service usage. The invention further allows the sending and receiving user equipment to set up dedicated channels (DCH) already during the start-to-talk procedure of the transmitting user equipment, which in turn potentially reduces end-to-end delays during the conversation.

7. A method of controlling a real-time media session, comprising:
-
establishing a real-time media session between first user equipment and second user equipment via a serving access network of the first user equipment, via at least a first media communication server, and via a serving access network of the second user equipment; and
sending, by one of the media communication server and a support node in a packet-switched core network during inactive periods of the real-time media session, dummy media towards at least one of the first and second user equipment in order to reset an inactivity timer of a common channel state in the serving access network of the respective user equipment and to thereby prevent the respective user equipment from going to an idle state. - View Dependent Claims (8, 9, 10, 11, 12)

13. A media communication server for providing real-time media sessions between user equipment located in one or more access networks, wherein:
-
the media communication server is configured to receive first signaling sent by first user equipment via a serving access network of the first user equipment in response to user'"'"'s action during an real-time media session established between the first user equipment and second user equipment;
the media communication server is configured to send second signaling towards the first user equipment upon receiving said first signaling;
the media communication server is configured to send third signaling towards the second user equipment upon receiving said first signaling; and
the media communication server is configured to send, immediately following one of the first, second, and third signaling, dummy media traffic towards one of the first and second user equipment in order to trigger a dedicated channel setup for the one of the first and the second user equipment in a respective serving access network prior to beginning an actual user media stream from the first user equipment. - View Dependent Claims (14, 15, 16, 17)
