Definitions

  • the local exchanges are addressed via their user interface and caused to broadcast the information.
  • this approach is based on the not entirely correct assumption of a single local network operator whose local exchange terminates all connections of a certain region and covers them with corresponding Local Area Codes (LAC).
  • LAC Local Area Codes
  • Subscribers beyond network boundaries to private networks (e.g., corporate networks) or competing public networks are only reached if the same broadcasting functionality and concurrent operator actions are taken in those networks.
  • private networks e.g., corporate networks
  • competing public networks are only reached if the same broadcasting functionality and concurrent operator actions are taken in those networks.
  • this can not be assumed in the large number of private networks of various sizes in particular.
  • Another problem is that even with knowledge of the participants to be notified behind a network boundary, the upstream switching network for rapid information due to the usually low bandwidths at gateways is unsuitable.
  • the invention has for its object to show a way how the accessibility of as many people in adjacent networks can be ensured in order to efficiently inform and communicate.
  • each gateway implicitly has an alerting profile.
  • each network it is not even necessary for each network to have an operator interface for the information of connected subscribers. Further, the user interfaces need not be opened for access by higher level population awareness systems, and subscriber data, network configuration, and availability and availability information need not be known across network boundaries.
  • the inventive method is independent of the network technology (TDM, IP).
  • existing switching nodes with moderate functional changes can be used, which already made investments of the network operator are secured and an extension to the functionality of the invention means only a small additional investment and risk.
  • FIG. 1 shows a network configuration consisting of 3 networks
  • FIG. 2 shows the playing of a warning to subscribers of two IP-based networks
  • Figure 3 the playing a warning to video telephony participants.
  • FIG. 1 shows a network configuration with 3 (sub) networks.
  • the networks are formed by local exchanges LE and transit exchanges TE. The intermeshing of the exchanges takes place via interim office bundles.
  • Each interim trunk group receives an alert profile, which is created when setting up the route / trunk group and, if necessary, as part of changes to the Network configuration is updated. Implicitly every network gateway has an alarming profile.
  • Part of the alerting profile may include a set of telephone numbers, a set of Circuit Identification Codes (CICs) (in ISUP based TDM gateways), a set of ISDN channels of a PRI / BA or analogue lines (for public network peer-to-peer and gateway gateways) private networks), a set of physical or symbolic destination address identifiers of a gateway (in IP based networks), a set of port numbers of a gateway determined by physical or symbolic destination address identifiers in IP based networks.
  • CICs Circuit Identification Codes
  • the alerting profile is set up consistently in the two exchanges terminating an interim exchange group.
  • the inter-office bundle can be reduced to a communication relationship between two call controllers, in which case corresponding profile information with regard to information services for population alerting can be stored and the communication relationship by the packet address of the remote node, a real or virtual point code, virtual embtsbündel or the like can be represented.
  • the interim office bundle is not considered in the context of a population warning.
  • the population warning is not transmitted via the affected bundle or the play is signaled to the associated remote call controller.
  • the alert profile identifies in an active in terms of population alert exchange, hereafter referred to as the originating exchange, whether and in what way a population alert on the interim bundle should be passed.
  • the profile indicates in a respect to the population warning not yet active exchange, hereinafter referred to as destination exchange, if and in what way a population warning about the interim bundle arrive and can be recognized as such.
  • the profile information of an interim bundle can be defined as a function of time. This means that, for example, it can not be set during the day, whereas at night it should be possible to forward population warnings via these bundles.
  • inter-office bundles described above can be defined between public exchanges or on the interface between public and private exchanges.
  • the originating exchange establishes a connection according to the defaults of the alerting profile for each interim office bundle, ie sets a corresponding telephone number or destination address, if necessary selects one of the required channels or a designated packet address / port number for this purpose and plays the population warning over the Inter-office bundle away.
  • the population warning can in this case be stored in an internal or external device controlled by this exchange, or it is sent after switching through the destinations only from an upstream interim office or a subscriber device, multiplied directly without caching and continue to transmit in the direction of the destinations.
  • a destination exchange triggers with the appropriate internal service logic on the arrival of a population warning on all according to Alerting profile provided for this purpose Intermediate bundles respectively channels. Triggering this can be the use of the special destination number as well as a special A-number, a line, an IP address, a port number or else the receipt of a special signaling message content (eg a message ID).
  • a special signaling message content eg a message ID
  • the population alert may be recorded and buffered in an internal or external device controlled by this exchange.
  • the destinations after the destinations have been switched through, they can first be transmitted via the reception-side inter-exchange cluster and directly multiplied without intermediate storage and forwarded in the direction of the destinations.
  • the originating exchange ensures that the said lines, numbers can not be reached by chance by a natural user of the network or that the signaling criterion can be set. This is done to protect against unwanted activation and abuse of function.
  • Switching centers can be both originating and destination exchanges. You have also defined the alerting profile described above for each route / trunk group. They then generate a call with the properties required in the profile if profile information is defined for the respective trunk group and the trunk group represents in particular a gateway or if it represents the connection to another switching center of the own network, which manages the alarm area to be reached or the route is supported there. If the call is answered from the far side, it will be displayed in the Media Server / Intelli- gent Peripheral deposited announcement or derived from this announcement to the population warning.
  • a Media Server or Intelligent Peripheral For caching and on-demand output, a Media Server or Intelligent Peripheral can be used. These units record the transmitted population alert and keep it ready for further processing. The information recorded in a Media Server / Intelligent Peripheral is optionally automatically checked for associated signaling information and content (e.g., speech recognition). Not-out-of-band signals that can be signaled or signaled can thus be detected in-band via keyword recognition.
  • signaling information and content e.g., speech recognition
  • the affected alerting area may be signaled, e.g. via the A-number or the sub-address and in the form of a Local Area Code (LAC). Alternatively, it can be detected via speech recognition. Accordingly, a new information message that is relevant for the addressed network is formed and the alerting bandwidth is determined. This results in the subordinate clusters and participant populations to be informed later. In particular, this covers network gateways to public and private networks.
  • LAC Local Area Code
  • a local exchange which receives a population alert via a signaled connection, transfers it economically and without network blocking to the affected user population, preferably with intermediate storage and use of broadcast technology.
  • Each destination switching center has mechanisms for recognizing population warnings of the same content arriving via different interim bundles. This happens, for example, by defining guard times and / or evaluating the outgoing message.
  • the originating and destination agencies optionally write tickets (CDR, CaIl Data Records) for each incoming and outgoing the Population Alert. These can be used for billing against the subscribers and the connected other network operators or the bodies triggering the population warning.
  • the originating exchange may initiate a dropping of connections to obtain the capacity to intercept the population warning, or a temporal monitoring may be started which will be inter-cached incoming warning message is connected.
  • the method can also be used in the IP environment (see Figure 2).
  • the population warning can be designed as a video announcement / multi-media reference.
  • a population alert may be issued by an authorized subscriber, e.g. a civil protection office, via its switching interface of its private branch exchange can be initiated in a simple manner.
  • the announcement text is thus up to date.
  • Complicated entries on the operating interfaces of a plurality of switching nodes involved are superfluous. Influence on a central alarming system for generating corresponding inputs at the operating interfaces of the switching nodes is not necessary. All competing networks are covered by a gateway. Decentralized use of local population information by local authorities is possible without further measures.
  • initial voice pauses which can be caused by the successive switching through several exchanges, are eliminated before each replay.
  • an intermediary Media Server can assign the corresponding key identify words and determine on the basis of a manageable by the operator list the affected local area codes, which then allows a destination exchange the direct addressing of subscribers or the passing on of the information about further intermediate clusters.
  • any other form of inband signaling such as B. DTMF sequences or FSK be used alternatively.
  • the fact of a pending population warning can also be signaled as at any other network border. This opens up the possibility of special and preferred treatment to the subscriber terminal.
  • a population alert by the subscriber terminal comes for example the automatic acceptance of the call, the switching of the audio signal on the speaker, the switching of the video signal or lack of a predefined content on the screen, as well as the caching of the content and its repeated output for the Case of trained as a set top box or PC user terminals in question.
  • a population warning interrupt the current television program received via DSL / cable / SAT and the viewer is immediately warned via the television.
  • FIG. 1 also shows the basic procedure of the method in a classical network topology based on TDM-based networks.
  • the network is formed by a plurality of local exchanges (LEs) and transit exchanges (TEs).
  • a local exchange PBX is introduced at one of the networks.
  • FIG. 1 also shows the playing of a current warning to subscribers of two conventional networks with a specific LAC.
  • the concerned local exchanges LE have means for recording and replaying the current announcement or have controlling access to them.
  • the affected transit exchanges TE manage without intermediate storage of the announcements by possibly delaying the transmission until they are switched to the first-mentioned means, making use of broadcasting and only allowing the announcement to be played by signaling the switching-on in the direction of the PBX.
  • the various recording means are already switched on and may pick up a non-existent signal, which is then removed again.
  • the alerting area is defined, for example, via the leading part of the local area code LAC, which is signaled, for example, via the subaddress in the forward direction.
  • FIG. 2 shows the basic procedure of the method in a modern network topology based on IP. This shows the playing of a current warning to participants of two IP-based networks with a specific LAC. It is assumed that the Access Gateway AGW at the network boundary to network 1 is able to support broadcast mode, ie a special form of conference. If this is not the case, deviating from the representation of the media server MS of the media gateway controller MGC at the network boundary to network 1, the announcement must first be recorded before it is transmitted in parallel or sequentially to the other media servers and then deleted.
  • FIG. 3 shows the basic sequence of the method for a video telephony suitable set top box STB of a TV set. This means that a current alert to video telephony subscribers is played via STB.
  • a population warning is the set top box STB eg by the source address 112 (fire / emergency) recognizable.
  • a telephone number will normally not be able to call a subscriber and is therefore suitable already to mark the population warning.
  • any other equivalent signaling form is permissible and can optionally be set up per participant profile in the CFS / MGC. If such a call arrives at the subscriber, the STB according to the procedure switches the warning message to the television while suppressing the TV outgoings that are in progress at the time of the warning.
  • the audio signal is switched through while a predefined still image stored for this purpose is displayed. Any mute of the device will be canceled if possible. If the set top box STB possesses means for recording, a recording of the indication and optionally cyclical playback or equivalent audiovisual indication of the reception of the population warning takes place. With operator actions or an explicit acknowledgment by the subscriber, the box STB returns to normal operation.
  • Profile information is created for identifying the type of processing of alerts at outgoing interim bundles as well as for detecting alerts on incoming interim bundle. Furthermore, the distribution function is triggered out of a single (possibly private) exchange and not by centralized operator actions on all exchanges connected with subscribers of different network operators.
  • Broadcast is used in a node for synchronous redistribution to a few destinations, caching the outgoing message for asynchronous and sequential information of a variety of destinations. This is a direct and quickest possible response of the targets to be informed by the supervising public or private exchange while sparing the capacity of the gateways and avoidance ensured double administration of subscribers in multiple switching nodes.
  • the alerting area can be defined and restricted by the optional automatic identification of information contained in the outgoing message.

Abstract

Selon l'état de la technique, la population est prévenue d'un danger par des informations véhiculées par le réseau de communication, par exemple en cas de risques majeurs ou de catastrophes écologiques imminents. Ce type de mode d'alerte/d'avertissement de la population est néanmoins très limité si le réseau de communication comprend une pluralité de réseaux secondaires, les informations (de prévention de danger) devant alors être transmises à l'abonné, au-delà les limites du réseau. L'invention pallie ce problème par allocation d'un profil d'alerte à chaque groupe d'itinéraires/de lignes. L'allocation s'effectue lors de la mise en place du groupe d'itinéraires/de lignes et est actualisée en cas de besoin dans le cadre de modifications de la configuration du réseau. Chaque interface de réseau comporte de manière implicite un tel profil d'alerte.
