Definitions
- a progressive integration of previously separate cation networks in communi ⁇ transmitted data such as voice data and data files is increasingly demanding a cross-network communication technology ⁇ .
- the non-real-time, packet-switched networks PVN previously provided for pure data transmissions are increasingly being used for voice services and voice band data transmission.
- the circuit-switched networks LVN one channel is switched exclusively for infor- mationsübertragung unlike the pa ⁇ ketverstofften networks PVN. This fulfills the for the
- a gateway unit a so-called gateway D, F are integrated at the transition between the two network types, ie at the periphery of the packet-switched network PVN.
- a gateway D, F generally provides a conversion and / or transcoding function between the various types of networks.
- a gateway For the data streams originating in a circuit-switched network LVN, a gateway has the functionality to package these and to deliver the packetized traffic to the packet-switched network PVN. For the data streams originating in WAN ⁇ mediated networks PVN this data conversion is executed in the opposite direction.
- the signaling for establishing a connection is established, for example, on the basis of a subscriber TInA via a line operating in Time Division Multiplex Technology TDM. switched network sent to a media gateway controller C. Via the media gateway controller C, the media gateways D and F associated with it, as indicated in FIG. 1, are activated.
- the media gateways the data necessary for the communication ⁇ construction the media gateway controller z. B. sent via Media Gateway Control Protocol or H.248 protocol.
- the actual voice connection is routed via the media gateways D, F and the internet protocol based network IPN.
- codecs are used with which the voice data is converted into IP packets.
- various codecs such. B. G .711a / ⁇ , G .723, G726 or G729.
- the voice data transmitted in the circuit-switched network by means of time division multiplexing are converted into data packets.
- the ITU Recommendation G .711 ⁇ be, for example, writes a transformation method for an audio compression and is used in ⁇ -law and A-law method.
- the compression method is based on a logarithmic conversion of a Audiosignais by means of a ⁇ J ⁇ J scoderrodul Bi i o ⁇ 13 ⁇ ⁇ : resolution, which is reacted according to the fourth isie ⁇ URQ by means of a logarithmic table in an 8-bit value.
- the implementation of the recommendation in accordance with G.711 in the A-Law process differs from that used in the ⁇ -Law process by different ones
- the codecs to be used are preset by the operator due to physical conditions or due to cost reasons. This has the disadvantage that in changing circumstances may be reduced, for example, the quality of egg ner voice data transmission or be blocked by an initially considered necessary adjustment Studentstra ⁇ generation capacity.
- the object of the present invention is to specify a circuit arrangement and a method with which a telecommunication subscriber can influence the transmission of his digitized data to be transmitted.
- the object is solved by the features specified in claim 1 or 5 features.
- the invention has the advantage that the As ⁇ tenübertragung can be influenced by a case by case basis and teilêtindividuel ⁇ le selection of a codec.
- the invention has the advantage that a telecommunication is munikationsteil alone able to select voice quality before or during a call, or to a ⁇ Since tenübertragung.
- the invention has the advantage that the operator can thereby offer the end customer additional business models, whereby the end user can also influence the charging.
- Figure 1 is a schematic representation of a connection between two participants
- Figure 2 is a block diagram.
- the invention provides in the area of IP-based telecommunications networks, a functionality that both the Operator Op ⁇ over and the end customer adds value. By offering a higher or lower compression, the telecommunications subscriber z. B. self-select a larger or smaller bandwidth for data transmission, which can also lead to a different billing.
- a variant embodiment is formed with first, second and third means.
- FIG. 1 shows in a simplified representation the interaction of individual modules between two subscribers TInA and TInB.
- both a network with time-division multiplexing technology TDM and a network with a based on an Internet technology administratda ⁇ tenvish IPN is indicated.
- the transition between the networks forms in each case a first and a second media gateway D, F.
- These first and second gateways D, F are controlled by a gateway controller C, which can also be called a softswitch.
- the Internet Protocol based network IPN is arranged between the first media gateway D and the second media gateway F.
- the media controller C is informed which codec is to be used for transmitting the digitized voice data via the internet protocol-based communication network IPN.
- a unit B in the time-division multiplex TDM network accepts the codec request signaled by the subscriber TInA and transmits this to the media controller C.
- the signaled information is evaluated and transmitted to the respective media gateway D, F, which then the actual Co- dec setting.
- the following settings can be initiated from ⁇ continuously from the participants to make a code change in the media gateway:
- a setting of a codec to use can be made before each call. For this purpose, by prefix from the calling sectionneh ⁇ mer, z. B. TInA the media controller C to tell which voice quality is expected by the calling party. By media gateway controller C reputation ⁇ number of the subscriber to be called by the participant can TlnA to this will be communicated to the media gateway controller C before entering.
- a manual input could also be replaced by a voice input.
- the terminal at the subscriber TInA sets to ⁇ example, the voice input of the subscriber in a manual input corresponding signaling.
- the calling party via an IN service controlled service, for. B.
- a co ⁇ dec can be made as independent of a call.
- a compression level desired by the participant may be overridden by the system on a case-by-case basis if technical constraints so require. B. if the far end can not provide the desired compression level, or if the service does not allow compression.
- FIG. 2 shows individual modules of the units shown in FIG. These units are the Time Division Multiplex Switch B, the Gateway Controller C and the Media Gateways D, F. Within the time-division multiplex switch B, a first evaluation module AM and a first signaling module SM are shown. In the media gateway controller C, a second signaling module GCSM and a second evaluation module GCA are arranged. A third signal evaluation unit MGA and an adjustment module MGEE are shown in the media gateway D, F. With the individual units or modules, the following functions are executed:
- First evaluation module AM The first evaluation module AM evaluates the subscriber signaling. It extracts the codec request of the subscriber and forwards it to a first signaling module SM.
- the first signaling module SM informs the media gateway controller C, for example, by means of the No .7 signaling that for the call between subscribers A and B, the codec is to be set in accordance with the subscriber request determined in the evaluation module AM.
- Second signaling module GCSM Second signaling module
- the second signaling module GCSM in the media gateway Cont ⁇ roller extracts the sig ⁇ from the first signaling module SM ized codec request and passes it to the second evaluation temdoul GCA.
- the second evaluation module GCA which can also be referred to as a delivery module , contains the central processing for the implementation of the desire for codec changes. To this belongs :
- the third signal evaluation module MGA receives the message from the second signaling module GCSM and informs an adjustment unit MGEE in the respective gateway that a codec change is to be made.
- the issuing entity MGEE executes the codec change in the media gateway and acknowledges via the third signal evaluation module
- first, second and third means are shown, wherein the first means the evaluation module AM arranged in the TDM switch B, the second means the provisioning module in the media gateway controller C and the third means MGEE the evaluation in the media gateways D and F arranged adjustment modules corresponds.
- ⁇ stuffs with the individual modules are each signaling associated with the as above communicate using data protocols.
