Abstract

A system, methods, nodes, and computer programs for transcribing of a communication session in a communication network are described. The communication network includes a control server for controlling the communication session, wherein the communication session is established between a user equipment and a remote end. The method includes that the control server receives a service indication indicating that a transcript of the communication session is requested and sends a transcription request for the communication session to a policy controller of the communication network. The policy controller determines at least one policy rule corresponding to the received transcription request and sends the determined at least one policy rule to a packet gateway node of the communication network. The packet gateway node provides, based on the at least one policy rule, a transcription or transcript chunk of at least one speech stream related to the communication session.

First claim

1 . A method for transcribing of a communication session in a communication network, the communication network comprising a control server for controlling the communication session, wherein the communication session is established between a user equipment and a remote end, the method comprising:
receiving, by the control server, a service indication indicating that a transcript of the communication session is requested; sending, by the control server, a transcription request for the communication session to a policy controller of the communication network, based on determining that the service indication has been received; determining, by the policy controller, at least one policy rule corresponding to the received transcription request; sending, by the policy controller, the determined at least one policy rule to a packet gateway node of the communication network; and providing by the packet gateway node, based on the at least one policy rule, a transcript or transcript chunk of at least one speech stream related to the communication session.

2 . The method according to claim 1 , wherein the transcript of the at least one speech stream is provided by sending the transcript from the packet gateway node, via the policy controller, and via the control server to a requesting entity.

3 . The method according to claim 1 , wherein the requesting entity is a subscriber using the user equipment requesting a transcript of the communication session via the user equipment.

4 . The method according to claim 1 , wherein the requesting entity is a further node of the communication network requesting a transcription of the communication session.

5 . The method according to claim 1 , wherein the service indication indicates that the transcript shall be provided as a continuous stream of transcript chunks, or wherein the service indication indicates that an entire transcript shall be provided after the communication session has ended.

6 . The method according to claim 1 , wherein the transcript is a conversion of the at least one speech stream to a corresponding text.

7 . The method according to claim 5 , wherein the transcribing involves a change of a language between the at least one speech stream and the corresponding text.

8 . A method in a user equipment for transcribing of a communication session in a communication network, the communication network comprising a control server for controlling the communication session, wherein the communication session is established between the user equipment and a remote end, the method comprising:
determining that a subscriber using the user equipment requests a transcript of the communication session; generating a service indication indicating that a transcript of the communication session is requested; sending the service indication to the control server, wherein the service indication is embedded in a signaling controlling the communication session; receiving the transcript from the control server, either as a continuous stream of transcript chunks, or as an entire transcript at the end of the communication session; and storing the received transcript in a local memory and displaying the received transcript to the subscriber.

9 . The method according to claim 8 , wherein the transcript is received from the control server via an instant messaging session and wherein the transcription chunks are received as text messages within the instant messaging session.

10 . The method according to claim 8 , wherein the entire transcript is received from the control server as a text message within the signaling controlling the communication session.

11 . A method in a control server for transcribing of a communication session in a communication network, the communication network comprising the control server for controlling the communication session, wherein the communication session is established between a user equipment and a remote end, the method comprising:
receiving a service indication indicating that a transcript of the communication session is requested; sending a transcription request for the communication session to a policy controller of the communication network, based on determining a service indication has been received; receiving a transcript from a policy controller either as a continuous stream of transcript chunks, or as an entire transcript at the end of the communication session; and delivering the received transcript to a requesting entity.

12 . The method according to claim 11 , wherein the requesting entity is a further node of the communication network requesting a transcript of the communication session.

13 . The method according to claim 11 , wherein the requesting entity is the user equipment and the service indication is determined by analysing a signaling controlling the communication session.

14 . The method according to claim 13 , wherein the service indication is an indication in a session description being embedded in the signaling controlling the communication session.

15 . The method according to claim 11 , wherein the transcription request for the communication session to a policy controller is comprised in an authorization request for the communication session.

16 . The method according to claim 11 , wherein the delivering of the received transcript is done by opening an instant messaging session with the requesting entity and delivering the received transcript chunks as text messages within the instant messaging session.

17 . The method according to claim 11 , wherein the delivering of the received transcript is done by sending the entire transcript as a text message to the requesting entity within an established signaling connection.

18 . A method in a policy controller for transcribing of a communication session in a communication network, the communication network comprising a control server for controlling the communication session, wherein the communication session is established between a user equipment and a remote end, the method comprising:
receiving a transcription request for the communication session from the control server; determining at least one policy rule corresponding to the received transcription request; sending the determined at least one policy rule to a packet gateway node of the communication network; receiving a transcript or transcript chunk from the packet gateway node; and sending the received transcript or transcript chunk to the control server.

19 . The method according to claim 18 , wherein the transcription request is comprised in an authorization request for the communication session.

20 . A method in a packet gateway node for transcribing of a communication session in a communication network, the communication network comprising a control server for controlling the communication session, wherein the communication session is established between a user equipment and a remote end, the method comprising:
receiving the at least one policy rule from a policy controller of the communication network; determining, based on the received at least one policy rule, at least one speech stream related to the communication session; transcribing, based on the at least one policy rule, the at least one speech stream related to the communication session; and providing, based on the at least one policy rule, a transcript or a transcript chunk of at least one speech stream related to the communication session.

21 . The method according to claim 20 , wherein a speech stream related to
