Beschreibungdescription
Anbindung eines Unified Messaging Systemes an eine VermittlungsstelleConnection of a unified messaging system to a switching center
Der Anmeldungsgegenstand betrifft ein System zur Steuerung eines Unified Massaging Systems.The subject of the application relates to a system for controlling a unified massaging system.
Unified Messaging Systeme (UMS) vereinen die verschiedenen Nachrichtentypen, die auf unterschiedlichen Kommunikationswegen transportiert werden, in einem gemeinsamen System mit dem Ziel, Medienbrüche zu vermeiden. Eine Nachricht kann den Benutzer als Sprach-, Text- oder Bildnachricht erreichen, die Nachrichtenübertragung erfolgt beispielsweise über Telefon, PC, Fax oder Pager.Unified Messaging Systems (UMS) unite the different message types that are transported on different communication channels in a common system with the aim of avoiding media breaks. A message can reach the user as a voice, text or picture message; the message is transmitted, for example, by telephone, PC, fax or pager.
Die meisten UM-Systeme werden heute von spezialisierten Firmen als Stand-alone Lösung angeboten. Das heißt für eine Nachrichtenübertragung über Telefon müssen diese Systeme auch Funktionen unterstützen, die typischerweise in Vermittlungs- stellen des öffentlichen Netzes realisiert werden. Dafür sind in den UM-Syste en entsprechende Ressourcen erforderlich, die nicht zur ursprünglichen Aufgabe der UM-Systeme, nämlich der Verwaltung aller Nachrichtenformate dienen. Diese Ressourcen binden unnötigerweise Speicher- und Laufzeitkapazität der UM- Systeme.Most UM systems are now offered by specialized companies as a stand-alone solution. In other words, for message transmission via telephone, these systems must also support functions that are typically implemented in switching centers in the public network. Corresponding resources are required for this in the UM systems, which do not serve the original purpose of the UM systems, namely the administration of all message formats. These resources tie up the storage and runtime capacity of the UM systems unnecessarily.
Wie oben erwähnt, sind Unified Messaging Systeme in der Regel als unabhängige (stand-alone) Lösungen realisiert. Die UM- Systeme unterstützen Funktionen zur Nachrichtenverwaltung wie beispielsweise automatische Weiterleitung, Benachrichtigung als auch Funktionen zur Nachrichtenkonvertierung wie 'Fax zu Text' oder 'Text zu Sprache'. Darüber hinaus müssen abrech- nungstechnische und vermittlungstechnische Funktionen bereitgestellt werden.As mentioned above, unified messaging systems are usually implemented as independent (stand-alone) solutions. The UM systems support functions for message management such as automatic forwarding, notification as well as functions for message conversion such as 'fax to text' or 'text to speech'. In addition, billing technical and switching functions are provided.
Bei einer sprachbezogenen Nachricht von oder zu einem Telefon müssen die Funktionen zur Herstellung einer Sprachverbindung im Unified Messaging System selbst implementiert sein. Das UM-System uss dazu die Steuerung zum Rufaufbau übernehmen.In the case of a voice-related message from or to a telephone, the functions for establishing a voice connection must be implemented in the Unified Messaging system itself. The UM system uss take over the control for the call setup.
Dem Anmeldungsgegenstand liegt das Problem zugrunde, ein Verfahren anzugeben, das die Anbindung von Unified Messaging Systemen an ein Vermittlungssystem ermöglicht unter gleichzeitiger Übernahme von vermittlungstechnischen Funktionen durch das Vermittlungssystem.The object of the application is based on the problem of specifying a method which enables the connection of unified messaging systems to a switching system while simultaneously taking on switching technology functions by the switching system.
Das Problem wird durch einen Gegenstand mit den Merkmalen des Anspruchs 1 gelöst.The problem is solved by an object with the features of claim 1.
Der Anmeldungsgegenstand bringt einen Funktionssplitt zwischen einem Unified Messaging System und einem Vermittlungssystem mit sich. Ziel dieses Splitts ist die Entlastung des UMS von klassischen vermittlungstechnischen Aufgaben, die nicht zu den ureigensten Funktionen eines Unified Messaging Systems gehören. Darüber hinaus wird dem Betreiber eines öffentlichen Netzes (z.B. den Telekommunikationsunternehmen) durch die Kombination von Vermittlungssystem und UM-System ein zusätzlicher Dienst aus einer Hand angeboten.The subject of the registration involves a functional split between a unified messaging system and a switching system. The aim of this split is to relieve the UMS of traditional switching tasks that are not part of the innate functions of a unified messaging system. In addition, the operator of a public network (e.g. the telecommunications company) is offered an additional service from a single source through the combination of switching system and UM system.
Der anmeld ngsgemäße Funktionssplitt beinhaltet einen Applikationsbaustein auf einer kommerziellen Plattform, der folgende Funktionen erfüllt:The functional split according to the application contains an application module on a commercial platform that fulfills the following functions:
- Bereitstellung einer Dienstelogik zum Aufbau einer Sprach- Verbindung zwischen 2 Anschlüssen, wobei einer der Anschlüsse den Besitzer oder den Nutzer einer Mailbox in einem UM-System darstellt; - Bereitstellung eines zugehörigen applikationsspezifischen- Provision of a service logic for establishing a voice connection between two connections, one of the connections representing the owner or the user of a mailbox in a UM system; - Provision of an associated application-specific
APIs (Application Programming Interface) zur Ansteuerung der o.g. Dienstelogik durch ein UMS.APIs (Application Programming Interface) to control the above Service logic through an EMS.
Das API stellt ein proprietäre Schnittstelle dar und ist auf die spezifischen Anforderungen für eine messaging-Applikation optimiert.The API is a proprietary interface and is optimized for the specific requirements of a messaging application.
Hieraus ergeben sich für den Betreiber des UMS einige Vorteile: - mit der Realisierung der Dienstelogik außerhalb des UM-This results in several advantages for the operator of the UMS: - with the implementation of the service logic outside the UM-
Systemes ist kein Wissen über die Abläufe im darunterliegenden Netz erforderlich; dies obliegt dem Lieferanten des öffentlichen Vermittlungssystemes, was seine Kernkompetenz darstellt; - die Definition eines einfachen - auf die Spezifika des Applikationsbausteines - beschränkten APIs erlaubt eine Reduzierung des Nachrichtenaustausches zwischen UM-System und Öffentlicher Vermittlungsstelle auf das notwendige; aus dynamischer Sicht wird das UM-System damit wesentlich entlastet.Systemes no knowledge of the processes in the underlying network is required; this is the responsibility of the supplier of the public switching system, which is its core competence; - The definition of a simple API - limited to the specifics of the application module - allows a reduction of the message exchange between the UM system and the public exchange to the necessary; From a dynamic point of view, this relieves the UM system considerably.
Vorteilhafte Weiterbildungen des Anmeldungsgegenstandes sind in den Unteransprüchen angegeben.Advantageous further developments of the subject of the application are specified in the subclaims.
Der Anmeldungsgegenstand wird im folgenden als Ausführungs- beispiel in einem zum Verständnis erforderlichen Umfang anhand von Figuren näher erläutert. Dabei zeigen: Fig 1 eine erfindungsgemäße, prinzipielle Funktionsaufteilung zwischen der Vermittlungsstelle mit integrierter kommerzieller Plattform sowie den externen Applikations- Servern undThe subject of the application is explained in more detail below as an exemplary embodiment to the extent necessary for understanding with reference to figures. 1 shows a basic division of functions according to the invention between the switching center with an integrated commercial platform and the external application servers and

In den Figuren bezeichnen gleiche Bezeichnungen gleiche Elemente. Der Anmeldungsgegenstand geht von einer Architektur aus, bei der eine herkömmliche Vermittlungsstelle mit einer zusätzlichen Plattform auf Basis kommerzieller Hardware ergänzt ist. Auf der Plattform werden spezielle Module (Applikationsblo- cke) implementiert, deren Funktionen extern über offene APIs gesteuert werden können.In the figures, the same designations denote the same elements. The subject of the application is based on an architecture in which a conventional switching center is supplemented with an additional platform based on commercial hardware. Special modules (application blocks) are implemented on the platform, whose functions can be controlled externally via open APIs.
Basierend auf dieser Architektur wird für die Anbindung eines UMS ein neuer Applikationsbaustein implementiert, der über ein applikationsspezifisches API die Funktionen dieses Bausteines zur Verfügung stellt. Der Applikationsbaustein ' es- saging' liefert Funktionen zum Aufbau einer Sprachverbindung zwischen dem Besitzer einer Mailbox auf dem UM-System und einem Nutzer dieser Mailbox.Based on this architecture, a new application module is implemented for the connection of a UMS, which provides the functions of this module via an application-specific API. The application module 'esaging' provides functions for establishing a voice connection between the owner of a mailbox on the UM system and a user of this mailbox.
Figur 2 zeigt eine herkömmliche Anordnung mit einem Ablauf ohne Einbindung des klassischen Vermittlungssystems.FIG. 2 shows a conventional arrangement with a sequence without integration of the classic switching system.
Figur 1 zeigt die prinzipielle Funktionsaufteilung zwischen der Vermittlungsstelle mit integrierter kommerzieller Plattform, die offene APIs anbietet (Backend Server) , und den externen Applikationsservern, die diese APIs nutzen (Frontend Server) . Ein Vermittlungssystem VS, das über eine interne Schnittstelle IIF (für: Internal Interface) mit einer kommer- ziellen Plattform CP (für: Commercial Platform) verbunden ist, weist die Funktionen Verbindungsaufbau VA, Vergebührung VG, Signalisierungsprotokolle SP und Zusammenarbeitungsfunktionen IW (für: Interworking) auf. Ein Unified Messaging System USM ist im Zuge einer auf dem Internetprotokoll IP basie- renden Verbindung mit der Plattform verbindbar, wobei die Verbindung über ein Application Protocol Interface API via CORBA (für: Common Object Request Broker Architecture) erfolgt. Das Verfahren soll am Leistungsmerkmal (Feature) 'Rückruf perFigure 1 shows the basic division of functions between the switching center with an integrated commercial platform that offers open APIs (back-end server), and the external application servers that use these APIs (front-end server). A switching system VS, which is connected via an internal interface IIF (for: Internal Interface) to a commercial platform CP (for: Commercial Platform), has the functions of establishing a connection VA, charging VG, signaling protocols SP and cooperation functions IW (for: interworking ) on. A Unified Messaging System USM can be connected to the platform in the course of a connection based on the Internet protocol IP, the connection being made via an Application Protocol Interface API via CORBA (for: Common Object Request Broker Architecture). The procedure should be based on the feature 'Callback by
Click' erläutert werden. Der Teilnehmer TEA mit einer Mailbox im UM-System hat die UMS-Einwahlnummer gewählt (1) . Der Ver¬ bindungsaufbau zum UMS erfolgt über das Vermittlungssystem, an das die kommerzielle Plattform angeschlossen ist und eine offene API-Schnittstelle anbietet. Der Applikationsblock Am registriert den ankommenden Ruf und leitet diesen an das UMS- System weiter (2) . Für den UMS-Teilnehmer TEA ist diese Einbeziehung des Vermittlungssystemes nicht sichtbar. Der UMS- Teilnehmer TEA findet in seiner Mailbox eine Nachricht und möchte den Absender (Teilnehmer TEB) telefonisch zurückrufen. Die Realisierung dieses Features im UMS liegt im Rahmen fachmännischen Könnens.Click 'are explained. The subscriber TEA with a mailbox in the UM system dialed the UMS dial-in number (1). The Ver ¬ connection setup for UMS via the switching system to which the commercial platform is connected and offers an open API. The application block Am registers the incoming call and forwards it to the UMS system (2). This involvement of the switching system is not visible to the UMS subscriber TEA. The UMS participant TEA finds a message in his mailbox and wants to call the sender (participant TEB) back by phone. The implementation of this feature in the UMS is within the scope of professional skill.
Zur Umsetzung des Features 'Rückruf per Click' wird vom UM- System die entsprechende API-Methode aufgerufen, die vom Applikationsbaustein auf der kommerziellen Plattform hierfür bereitgestellt wird (3) . Diese Methode enthält alle Informationen, die für einen Verbindungsaufbau zwischen Mailbox- Besitzer und Nachrichtenabsender erforderlich sind. Der Verbindungsaufbau wird nun vom Applikationsbaustein gesteuert, der dem zugehörigen Vermittlungssystem die Anforderung über die interne Schnittstelle weiterleitet. Die gesamte Verbindung (Aufbau einschließlich Überwachung, Gesprächsphase und Abbau) wird vom Applikationsbaustein völlig separat vom UM- System kontrolliert/gesteuert. Der Applikationsbaustein löst die Sprachverbindung zwischen Vermittlungssystem und UMS, baut stattdessen die Verbindung zum Absender der Mailbox- Nachricht auf und verbindet anschließend UMS-Mailbox-Besitzer und Absender (4) .To implement the 'Callback per click' feature, the UM system calls the appropriate API method, which is provided by the application module on the commercial platform (3). This method contains all the information required to establish a connection between the mailbox owner and the message sender. The connection establishment is now controlled by the application module, which forwards the request to the associated switching system via the internal interface. The entire connection (setup including monitoring, conversation phase and removal) is controlled / controlled by the application module completely separately from the UM system. The application module clears the voice connection between the switching system and the UMS, instead establishes the connection to the sender of the mailbox message and then connects the UMS mailbox owner and sender (4).
Das UM-System wird über Erfolg bzw. Misserfolg des Verbindungsaufbaus mit einer entsprechenden API-Methode nach voll- ständigem Verbindungsabbau durch den Applikationsbaustein informiert. Diese Methode beinhaltet auch weitere Daten, die das UMS beispielsweise für Vergebührungs-, Verkehrsmess- oder Statistikaspekte benötigt. Die Steuerung geht wieder vom Applikationsbaustein an das Unified Messaging System über. The UM system is informed of the success or failure of the connection establishment with an appropriate API method after constant connection clearing informed by the application module. This method also includes other data that the UMS needs, for example, for charging, traffic measurement or statistical aspects. Control passes again from the application module to the unified messaging system.
