Definitions
- the invention relates to a method for transmitting a subscriber signaling of an analog connection of the public telephone network in an IP network and the structure of this network.
- CIP Callmg Line Identification Presentation
- AOC Advanced Organic Chemical Network
- SMS Short Message Service
- MMI Message aitmg Indication
- These signals are usually transmitted in the public telephone network in the form of FSK signals in accordance with the European Telecommunications Standard ETSI ETS 300 659, but which, in addition to the aforementioned services, also provide additional information about the call, e.g. the existence of a call diversion or the type of call can include.
- the Media Gateway Control protocol in accordance with RFC2705 is provided for the transmission of information for subscriber signaling of analogue connections of the public telephone network in IP networks.
- the invention is therefore based on the object of developing the prior art in such a way that a simple and effective method for transmitting subscriber signaling of an analog connection of the public telephone network in an IP network is available via the media gateway control protocol.
- the invention includes the essential idea of modifying the existing standard of the Media Gateway Control protocol according to RFC2705 by means of a specially coded "signal requests parameter". It is proposed to use the "Analog Display Service Interface (adsi)" signal, which is provided in the Media Gateway Control protocol according to RFC2705 for the transmission of FSK signals, but is not specified there, as part of the "Signal Requests Parameter”.
- the signal adsi which, in the specification according to the invention, consists of two parameters, each of which is formed from the character chains mentioned.
- the first character string listed consists of one character and characterizes the Alertmg method. With the character “0", the transmission of the FSK signal does not require an alert sequence, and it applies to the transmission of an FSK signal during the call cadence.
- the character “D” is FSK signaling using the DT-AS Alertmg sequence and "P” is FSK signaling using the RP-AS Alertmg sequence.
- the signal adsi can contain the character "F” in the first character string mentioned, which is used to transmit an FSK signal during the call.
- the second string contains the complete one Message from the FSK data protection layer, starting with the "Message type" field. Since the message from the FSK data protection layer has a binary format, but the Media Gateway Control protocol is ASCII text-oriented, each byte of the FSK data protection layer is encoded as a hexadecimal character.
- a major advantage of the invention lies in the fact that with the introduction of a single coded "signal requests parameter", the information for the various FSK signaling, such as CLIP, CNIP, etc., is now in the Media Gateway Control protocol in an IP network can be transferred easily.
- additional information such as the presence of a call diversion or the type of call can also be transmitted effectively with the specified signal adsi.
- the fact that the coding allows the existing software basis to be used largely unchanged is also particularly advantageous.
- Fig. 6 shows the third part of an embodiment of the invention.
- Fig. 7 shows the fourth part of an embodiment of the invention.
- the message format of the FSK data protection layer is shown in FIG.
- the data link layer is responsible for the performance activation / deactivation, transmission control, transmission error monitoring, block synchronization and selection of the suitable transmission path from several available physical transmission paths.
- Part of the message of the data protection layer is the message of the presentation layer, in FIG. 1 a “Presentation Layer Message”, which is shown schematically in FIG. 1 b.
- the presentation layer specifies the format and the sequence of information that is passed on from the subscriber exchange to a terminal. In an embodiment of the invention, which is shown in FIG. 2, these messages which have just been presented are transmitted in MGCP format in an IP network.
- Figure 2 shows an example of a message from the FSK data link layer for the alert method "0", i.e. it is not an alert sequence for transmitting an FSK signal during the call cadence required.
- the binary message of the FSK data protection layer is shown in the table.
- the signal adsi which contains the above-mentioned two character strings, the alert method and the complete message of the data link layer, starting with the field "Message type", included.
- IP network 3 shows the structure of a special form of an IP network zes, a Voice-over-IP network.
- IAD Integrated Access Device
- ATM-node forms the interface to an ATM-node, in turn, the near about em edge device with a non- designated IP network is connected.
- IAD Integrated Access Device
- the signaling is transmitted in H.323 or MGCP format to a media gateway controller (MGC), while the speech is sent via various servers (IP over DiffServ) to a media gateway (MG), which is the interface to a public telephone network (PSTN) forms, is transmitted.
- MGC media gateway controller
- IP over DiffServ IP over DiffServ
- MG media gateway
- PSTN public telephone network
- the signaling can be transmitted by the MGC directly using ISUP ms PSTN.
- the media gateway is controlled from the MGC using the MGCP protocol.
- FIGS. 4 to 7 form a representation of an exemplary embodiment of the invention for transmitting the FSK signaling "Callmg Line Identification Presentation (CLIP)".
- the communication between the media gateway controller (MGC) 1 and the media gateway, here an Integrated Access Device (IAD) 2 takes place in the form of the media gateway control protocol (MGCP) according to the invention with the correspondingly coded "signal requests parameter" in the form of the signal adsi.
- IAD Integrated Access Device
- the incoming call is received by the MGC 1 e and the command Create Connection is then sent to the IAD 2 in step (1) in order to establish a connection.
- the IAD 2 acknowledges this command in step (2).
- step (3) of MGC 1 sent a notification request to IAD 2, which contains the signal Initial Ring and the event Operation Complete.
- the Initial Ring signal indicates that the IAD 2 should create a (generally shortened) first ring tone, while the Operation Complete event means that the MGC 1 should be notified after the Initial Ring process has been completed.
- IAD 2 acknowledges the notification request from (3) and, after the initial ring signal has been applied to the analog subscriber line 3, that is, the connected telephone has been ringing for the first time, the operation complete message in step (5) to MGC 1, the receipt of which is acknowledged in step (6).
- the MGC 1 transmits the IAD 2 em notification request with the signal Analog Display Service Interface (adsi) and the event Operation Complete.
- This signal adsi contains the FSK data for the Call g Line Identification Presentation (CLIP).
- IAD 2 acknowledges the transmission in step (8).
- the operation Complete message is transmitted to MGC 1 in step (9), the receipt of which is acknowledged by MGC 1 in step (10).
- step (11) sends the MGC 1 to the IAD 2 a further notification request with the signal Ringmg, which is followed by the acknowledgment by IAD 2 in step (12).
- the Rmging signal initiates normal call cadence with 1 s ringing and 4 s silence.
