Definitions

  • Network operators and independent service providers are increasingly interested in convergent services based on presence information.
  • Network operators and service providers are constantly looking for innovative value-added services that open up new market potential and enable differentiation from the competition.
  • Presence-based services are becoming increasingly popular due to the spread of the SIP standard [1,2] in telecommunications networks and the spread of SIP-capable personal computer software clients (Microsoft Windows XP including the so-called messenger should be mentioned here in particular).
  • SIP standard [1,2] in telecommunications networks
  • SIP-capable personal computer software clients Microsoft Windows XP including the so-called messenger should be mentioned here in particular.
  • Presence server a special server in the IP network (so-called presence server) primarily collects the information about which IP subscriber can currently be reached at which end device or under which IP address. For this purpose, the respective IP subscribers send special messages, ie messages with presence information to the presence server. Servers that want to use the presence information of certain subscribers for new value-added services can query this from the presence server [5,6]. Examples of presence-based services are instant messaging (exchange of chat messages as soon as a certain IP participant is online) or instant conferencing (setting up a telephone or video conference as soon as the desired IP participants are online).
  • IP network functions in the IP network are linked to functions in PSTN networks, such as the initiation of a PSTN call via a web page ("click-to-dial") or the initiation and Control of a conference in the PSTN via a web page.
  • PSTN Next Generation Networks
  • NTN Next Generation Networks
  • Pres-called Pres-based services have only been offered for IP subscribers, ie it is assumed that the subscriber has an IP-capable device - for example a Java-enabled mobile device or a PC with Microsoft Messenger - which allows him to do so using a SIP-based protocol to transmit its presence information. So far, only a presence URI has been accepted as the contact address or identification address under which the IP subscriber can store his presence information [3, 4].
  • a PSTN subscriber or IP subscriber it is now possible for a PSTN subscriber or IP subscriber to be able to transmit so-called "presence" information via a standard telephone terminal that is common today, and thus to be able to indicate that he is currently
  • Convergent presence-based value-added services are typically based on servers in the IP network, which can control or influence connections via suitable interfaces to switching units (these can also be referred to as switching servers).
  • FIG. 1 shows an exemplary network architecture according to the invention:
  • the network architecture shown is based on an IP-based network.
  • the components have the following functions or tasks:
  • a presence server enables an IP subscriber to register presence information, i.e. the storage of information as to whether the IP subscriber is currently reachable or not.
  • IP subscriber can also provide additional information, e.g. Mood ("wants to be left alone", “look forward to messages") or brief information ("I can only be reached in 1 hour”.)
  • a service server contains the service logic for a value-added service. It has a suitable interface to a switching unit that allows connections to be controlled. He also has an interface (eg SIP-based) to a presence server, via which he can query the presence information of certain IP users. He can via another interface to the switching unit For example, control the establishment of a connection between IP subscribers with the presence information "subscriber is currently online and available".
  • a switching unit that allows connections to be controlled. He also has an interface (eg SIP-based) to a presence server, via which he can query the presence information of certain IP users. He can via another interface to the switching unit For example, control the establishment of a connection between IP subscribers with the presence information "subscriber is currently online and available".
  • the IP subscriber terminals e.g. a multi-media PC, have a suitable interface (e.g. SIP based) to transmit their presence information to the presence server. Call control and voice transmission is also IP-based.
  • a switching unit controls the connection establishment for the assigned IP subscribers. It also contains components for speech dialogues or conferences.
  • Traditional PSTN participants can be included via a gateway. The gateway can of course also be integrated in the switching unit.
  • a PSTN subscriber has a standard PSTN telephone. The participant is therefore only able to use a simple voice connection.
  • the invention makes it possible for the PSTN subscriber to be able to transmit presence information (for example "subscriber can now be reached under telephone number xyz") to the presence server.
  • This is achieved in that the switching unit transmits presence information for a subscriber to a presence server instead of a PSTN subscriber.
  • the switching unit obtains the relevant information from the PSTN subscriber, for example by means of special subscriber signaling or by means of an interactive voice dialog with the PSTN subscriber, and then sets this information on an IP-based protocol [3, 4] for the presence server understandable format.
  • the switching unit then transmits the information formatted in this way to the presence server.
  • the switching unit itself however, this is only the protocol endpoint from the perspective of the presence server and not the actual PRESENTITY.
  • the actual PRESENTITY is the PSTN participant.
  • a switching unit acts towards the presence server on behalf of many PSTN participants.
  • the switching unit obtains the relevant information using an interactive voice dialog with the PSTN subscriber
  • the switching unit controls the voice-controlled dialog using an announcement unit and thus collects the relevant information from the PSTN subscriber.
  • the switching unit transmits presence information to the presence server in the name of the PSTN subscriber via an IP-based interface (e.g. SIP-based).
  • IP-based interface e.g. SIP-based
  • the presence server thus also receives presence information from a PSTN subscriber, which is then from one
  • Service server can be evaluated and taken into account for services.
  • the method according to the invention therefore allows a PSTN subscriber to also store presence information with the presence server, specifically via the switching unit.
  • the contact or identification address for the presence information must be an E.164 telephone number, because only under this can the PSTN subscriber be reached.
  • the method according to the invention also makes it possible to store a contact address as a PRESENTITY for a PSTN subscriber at the presence server, the normal E.164 telephone number being used as the contact address. However, this presupposes that the Presence Server can treat E.164 numbers as contact addresses. This can be taken into account in the context of standardization or implemented in a proprietary manner.
  • PSTN subscribers can also use presence-based services. This is not possible with the current state of the art.
  • the presence information based on an E.164 number is not limited to the exclusive use for PSTN participants. It can also be used as an optional addition to the URI-based contact addresses previously discussed in the IETF. Based on a current status indication, the PRESENTITY could then indicate that it can currently only be reached via the registered E.164 address.
  • the method according to the invention increases the attractiveness of a presence-based service by integrating PSTN subscribers.
  • the presence data are transmitted by means of a voice dialog, the following additional advantages result.
  • the PTSN subscriber can transmit the presence information from any telephone (landline or mobile phone). (Prerequisite: The switching unit allows the update of presence information • regardless of the subscriber CLI (Calling Line Identity)) • For the network operator (if not the same service provider)
  • the method according to the invention generates additional conversation volume through the speech dialogues.
  • the announcement unit for realizing the voice dialogue can either be integrated in the switching unit or be connected or controlled separately via suitable interfaces.
  • the control logic for controlling the announcement unit can either be integrated in the switching unit or on a separate server, e.g. on an IN SCP (Intelligent Network Service Control Point).
  • IN SCP Intelligent Network Service Control Point
  • the switching unit performs an automatic authorization check on the CLI of the PSTN subscriber, the function can only be carried out from the home terminal. If such a check is not carried out, but the authorization check is carried out on the basis of information which is queried by means of a voice dialog, the PSTN subscriber can use any fat network / mobile terminal.
  • the service server and the presence server can be physically integrated or separated.
  • An example of application of the invention to the presence-controlled “instant conference service” is shown below with the aid of FIG. 2.
  • the interfaces shown here for presence (here: registration, query) and call control for IP users are SIP-based. It is assumed that this is currently The specifications discussed in the IETF SIMPLE Working Group are based [3, 4, 5, 6]
  • the function of the "Instant Conference Service” is to automatically set up a voice conference between several participants as soon as they can be reached. Accessibility is determined on the basis of presence information that the instant conference server learns from a presence server.
  • a conference is to be set up between the two SIP participants 1 and 2 and the PSTN participant as soon as all participants can be reached.
  • the two SIP participants have a multi-media PC with a SIP client. This enables you to set up IP-based voice and video connections as well as exchange presence information with a presence server.
  • the PSTN subscriber only has the option of a voice connection.
  • the two SIP participants update their presence information directly via their client software in the presence server.
  • the PSTN subscriber dials a special service number that connects him to the switching unit. He is authorized to use voice-controlled presence information transmission. In this application example, this authorization should be based on the CLI.
  • the switching unit / announcement unit uses voice dialogue to determine that the subscriber is now available under his home connection. This information is converted into a SIP-based protocol and sent from the switching unit to the presence server. det. As soon as the instant conference server learns (options:
  • Presence Server reports status changes or the service server periodically queries) that the required PSTN subscriber can be reached, he starts the conference call. This is done using a suitable protocol between the instant conference server and the switching unit.
  • the PSTN subscriber is integrated using a voice connection. Depending on the client options, a parallel video connection via IP would also be possible between the two SIP subscribers.
