Definitions
- the invention relates to a method for setting up a multimedia connection
- the Internet Protocol IP is responsible for the connectionless transport of data from one sender - possibly over several networks - to the receiver at level 3 of the OSI layer model, whereby neither error detection nor error correction takes place.
- Transport Protocols such as the Transmission Control Protocol TCP or User Datagram Protocol UDP are set up on the Internet Protocol, and in turn a scarcely manageable variety of different, in some cases competing, application protocols, such as, for example, http, ftp or for the management of multimedia connections the so-called SIP protocol or the ITU standard H.323.
- H.323 For multimedia connections on the Internet there are currently two competing standards for signaling: H.323 and SIP.
- the ITU standard H.323 (ITU: International Telecommunication Union) was developed for the real-time transmission of multimedia applications such as voice and video communication in packet-oriented networks.
- Umbrella As the so-called Umbrella standard, it houses a series of protocols, such as signaling, exchange of terminal functionalities and status information as well as connection and data flow control.
- the most important protocols of the H.323 standard include H.225, H.245 and H.450.x.
- H.225 describes signaling protocols such as RAS (Registration, Admission, Status) and Call Signaling.
- H.245 acts as Control Protocol for Multimedia Communication.
- the H.450 standard defines additional telephony functions in order, for example, to map the features of ISDN to IP.
- the ITU-T standard Q.1902.XBICC CS2 (bearer independent call control capability set 2 ) and Q.765.5 BAT (bearer application transport) specify in parallel and alternatively also how known services can be realized.
- the Session Initiation Protocol SIP was developed by the IETF (Internet Engineering Task Force). The standard defines a signaling protocol for setting up, modifying, and terminating sessions with two or more participants.
- the session initiation protocol SIP likewise serves for the transmission of real-time data via packet-based networks and is functionally comparable to the protocols according to ITU standard H.323:
- the session initiation protocol SIP can mediate interac ⁇ tive communication services including voice over IP networks , the transport works via TCP (Transmission Control Protocol) or UDP (User Datagram Protocol).
- TCP Transmission Control Protocol
- UDP User Datagram Protocol
- the Session Initiation Protocol SIP is responsible for the call signaling as well as the localization and registration of users. In particular, it also allows the transmission of the identity of the caller and the call forwarding in IP networks.
- Session Initiation Protocol SIP is text-oriented, based on HTTP (Hypertext Transfer Protocol) and thus offers an open internet-based structure. For this reason, new performance characteristics can be implemented relatively easily and quickly.
- HTTP Hypertext Transfer Protocol
- the two aforementioned standards are constantly being developed. Examples are more recently Q.1912.5 "Interworking SIP and BICC / ISUP" for ITU-T and RFC 3366 "SIP Basic call flow examples" for IETF.
- the invention is therefore based on the object to further develop multimedia connections to the standards mentioned.
- This object is achieved according to the invention with a method for establishing a multimedia connection via packet-switching computer networks between at least one calling subscriber and at least one called subscriber, wherein the call is set up via at least one other subscriber and the at least one called subscriber transmits his status the at least one further subscriber signals in which the at least one further subscriber signals the status of the called subscriber to the calling subscriber.
- the session initiation protocol as the signaling protocol and when the further participant signals the status of the called subscriber by means of the signaling message 183 according to the session initiation protocol to the terminating subscriber.
- subscriber designates not only persons, but also machines of all kinds, such as Anrufbe ⁇ answerers and automatic user programs (applications) that can exchange multimedia messages.
- any type of information transmission is conceivable as a multimedia connection.
- the embodiment relates to the case of a call from a so-called A-subscriber to another subscriber.
- the B-subscriber has activated the feature "call forwarding" so that the call is diverted to a third, the so-called C-subscriber
- All three subscribers are connected to a packet-switching computer network, which may be so-called IP - Telephones act, soft clients (programs on computers), o- but also to all kinds of machines, such as An ⁇ answering machine and automatic user programs (Applikati ⁇ ones), the multimedia messages can exchange.
- the participants use the Session Initiation Protocol or SIP-T etc as a signaling protocol.
- the A-subscriber does not receive a dial tone in such a sequence, since according to the present standard there is no control for this case.
- the state of the "ringer” is now signaled to the B subscriber by means of the signaling message 180 "ringing" according to the session initiation protocol to the further, redirecting B subscriber in such a call setup by the C subscriber.
- the task of the B-subscriber can also be an alternate server, such as e.g. take over a SIP "application server”.
- Session Progress which according to Session Initiation Protocol itself is used to transmit information about the progress of the call setup, in order to signal according to the invention to the calling A subscriber that a dial tone should be set.
