Control of Session Parameter Negotiation for Communication Connection
First Claim
1. A session control function in a communication system, comprisingmeans for determining a first media type indicated for a session associated with a dialogue;
- means for determining a second media type indicated for an early media associated with the dialogue;
means for comparing if the first media type and the second media type are the same; and
means for transmitting to a policy control entity, parameters relating to the early media in the same session information media component than parameters relating to the session, if the first media type and the second media type are the same.

6. A method of controlling an establishment of a communication connection, comprising:
-
determining that the same media type is indicated for early media associated with a dialogue and for a session associated with the dialogue; transmitting to a policy control entity parameters relating to the early media in the same session information media component as parameters relating to the session. - View Dependent Claims (7, 8)

9. An apparatus, comprising,
a session unit configured to receive session control signaling according to session initiation protocol (SIP) associated with a session and to extract session description protocol (SDP) information encapsulated in the received SIP signaling; -
a detecting unit configured to detect an early session disposition and a session disposition in the SDP of the SIP signaling associated with the session; a comparing unit configured to compare the early session disposition and the session disposition and to determine if a single media line with one media type is contained in the early session disposition and if a single media line with the same media type is contained in the session disposition; and a describing unit configured to describe both media lines in a single session information media component towards a policy control entity by using the same media component number if the both media lines are of the same type.
