Abstract

The present invention discloses a solution for performing a sharing an ongoing data session between a first user and a group of at least one additional user in a telecommunication system. The basic idea of this invention is to provide a network integration node with a shared streaming session logic, replication logic and group membership management functions of a conference node, like for example the “Push to-talk over Cellular (PoC)” application. Using this functionality the conference system is to be included into the ongoing streaming session, shall invite additional members and forward the streaming traffic to them as well. This results into a shared streaming service using unicast communication resources.

Claims

1. A method performed in a network integration node for sharing an ongoing data session between a first user and a group of at least one additional user for a telecommunication system having the network integration node for data session proxying and a server for providing the data session to the first user, said method comprising:

performing a data session proxying procedure to track the data session established by the first user,

receiving a request from the first user for sharing the data session with the group of at least one additional user.

performing a conference establishment procedure to a conference node handling the group of at least one additional user for binding the network integration node to the conference node as a party of a conference by establishing a second data session connection to the conference node, and

performing a replication procedure for triggering a replication of the data session to the group of at least one additional user over the second data session connection.

2. The method according to claim 1 wherein the network integration node performs the replication of data packets of the data session to the conference node and to the first user.

3. The method according to claim 2 wherein the network integration node during the replication creates a number of copies of the data packets to multiple destination of which at least one is the conference node.

4. The method according to claim 1 wherein the conference node performs the replication of data packets of the data session to the group of at least one additional user and also to the first user by establishing a connection to said first user wherein the data packets of the data session are forwarded from the network integration node.

5. The method according to claim 4 wherein the data session from the integration node to the first user is closed down.

6. The method according to claim 1 wherein the network integration node replicates data packets of the data session until said data packets reach the first user via the conference node.

7. The method according to claim 1 wherein the first user indicates in the request being sent to the network integration node a group identifier of the group of at least one additional user.

8. The method according to claim 7 wherein the message is an extension of the Radio Streaming Session Protocol, RTSP or http.

9. The method according to claim 1 wherein charging records for the first user and the additional users of the group of the at least one additional user are collected.

10. The method according to claim 1 wherein floor control function is implemented in the network integration node and/or in the conference node in order to allow the at least one additional user to control the data session instead of the first user.

11. A network integration node in a telecommunication network, adapted to perform a sharing of an ongoing data session between a first user and a group of at least one additional user said network integration node comprising:

proxy logic for proxying a data session provided by a server to the first user,

reception controller for receiving and evaluating a request received from the first user for sharing the ongoing data session with the group of at least one additional user,

binding controller for binding the network integration entity as a conference party to a conference node handling the group of the at least one additional user wherein said binding controller is adapted to establish a second data session connection to the conference node and

replication logic for triggering a replication of the data session to the group of at least one additional user wherein the second data session connection is used to transmit data session to the conference node.

12. The network integration node according to claim 11 wherein the reception controller has a logic for evaluating a group identifier included in the request from the first user and wherein said group identifier is used in a communication with the conference node.

13. A system in a telecommunication network adapted to perform a sharing of an ongoing data session between a first user and a group of at least one additional user wherein said system comprising:

a network integration node comprising;

proxy logic for proxying a data session provided by a server to the first user,

reception controller for receiving and evaluating a request received from the first user for sharing the ongoing data session with the group of at least one additional user,

binding controller for binding the network integration entity as a conference party to a conference node handling the group of the at least one additional user wherein said binding controller is adapted to establish a second data session connection to the conference node, and

replication logic for triggering a replication of the data session to the group of at least one additional user wherein the second data session connection is used to transmit data session to the conference node, said network integration node communicating with a conference system providing conference service to a group of users and with a first user being adapted to sent a request to the network integration node for sharing the ongoing data session with the group of at least one user,

said network integration node further comprising means for;

performing a data session proxying procedure to track the data session established by the first user.

receiving a request from the first user for sharing the data session with the group of at least one additional user,

performing a conference establishment procedure to a conference node handling the group of at least one additional user for binding the network integration node to the conference node as a party of a conference by establishing a second data session connection to the conference node, and

performing a replication procedure for triggering a replication of the data session to the group of at least one additional user over the second data session connection.
