Definitions

  • the present invention relates to a personalized greeting service method, comprising setting up a telephone call in a telecommunication network between at least two user terminals in which a personalized greeting is used, in which the telephone call is set up using circuit switched signaling.
  • Prior art A personalized greeting service is applied in present day mobile telephony systems (GSM).
  • GSM mobile telephony systems
  • user A calling party
  • user B called party
  • user A gets a music or voice clip (according to B's choice) instead of a ring back tone.
  • the content (the voice clip) is delivered via the speech path between user A and the network.
  • this speech path would be used to deliver ring back tone, now the same speech path is used to deliver the voice clip.
  • This service is however limited to audio (a voice clip) as it uses the conventional circuit switched (CS) connection path between user A and user B.
  • CS circuit switched
  • the PGS service must be able to determine that the terminal of user A is capable of receiving the video clip, or assume it does (which may cause unexpected service behavior for user A).
  • a session initiation protocol (SIP) session is used, but then, the PGS service must determine the uniform resource identifier (SIP-URI) of the terminal, before it can send a SIP INVITE message to the terminal signaling that multimedia content is available.
  • SIP-URI uniform resource identifier
  • a SIP-URI may be registered at more than one terminal, so also, the PGS service needs to identify the correct terminal from which the CS call originated.
  • a reference must be included to the CS call, to make the association between the SIP session and the CS call.
  • the terminal of user A must be able to receive the SIP messages (such as SIP INVITE) and be arranged to take the appropriate actions. Also, the terminal must be registered to indicate that it is able to receive SIP messages for user A. It may happen that the terminal of user A is equipped to provide packet switched connections such as GPRS, but that the GPRS connection is not available for some reason at the time the PGS service wants to set up a SIP session. Then first, the PGS service must set up the GPRS connection to that terminal, which requires many steps when initiated from the network. E.g. the network must know the geographic location of the terminal in order to establish which base station is serving the specific terminal.
  • SIP messages such as SIP INVITE
  • the present invention seeks to provide a multimedia personalized greeting service which is easier to implement in existing telecommunication networks, and at less cost than the existing methods.
  • a personalized greeting service method according to the preamble defined above is provided, further comprising adding multimedia information data to the circuit switched signaling. If desired, the multimedia information data is used for receiving multimedia content in one of the at least two user terminals.
  • the present method is easy to implement and allows to bring personalized multimedia greetings, including video data, to user terminals.
  • the present method requires less complex processing than the existing video greeting methods.
  • the present invention may be used to retrieve a personalized greeting message associated with the called party.
  • the reverse scheme could be used, wherein a called party receives a personalized greeting message from the calling party.
  • the multimedia information data comprises at least a reference to a multimedia content location reachable using the telecommunication network, such as a uniform resource locator (URL). This allows the user terminal receiving the multimedia information data (which can be either a calling terminal or a called terminal) to take responsive action to retrieve the multimedia content.
  • URL uniform resource locator
  • the multimedia information data may in a further embodiment comprise a call reference number (CRN).
  • CRN call reference number
  • Such a CRN which uniquely identifies the call being set up between the at least two terminals, may be used at various instances in the present method for identification and verification purposes.
  • the multimedia content to be transferred is identified at the multimedia content location using the call reference number (CRN).
  • a calling party number (CgPN) and a called party number (CdPN) may be used in addition.
  • the CRN may be verified to check whether the circuit switched connection associated with the call reference number is still in a set up phase, in order to assure the call actually exists and is in the alerting phase.
  • the multimedia content location may be associated with a multimedia database in the telecommunications network, which may be implemented using a separate unit in the network (content server) or using an existing network unit.
  • the multimedia content location is associated with a specific one of the at least two user terminals.
  • a user may store a personalized multimedia greeting on its own user terminal, which may be retrieved from there.
  • the multimedia information data may comprise an IP address of the specific one user terminal.
  • the multimedia content may be retrieved using a number of alternative mechanisms.
  • the method further comprises retrieving the multimedia content using a session initiation protocol (SIP) request to the multimedia content location.
  • SIP session initiation protocol
  • a SIP session may be initiated for transfer of the multimedia content, or the multimedia content is transferred in the telecommunication network as data payload in a SIP message.
  • the latter option limits the size of the multimedia content to the data payload size, but this may still suffice for a personalized multimedia greeting.
  • the method further comprises retrieving the multimedia content using a hyper text transfer protocol (http) request to the multimedia content location.
  • the multimedia information data may in this case comprise a well known http URL.
  • transfer of the multimedia content is stopped when the call is answered. Answering of the call by the called party may be detected by normal network detection (even using circuit switched signaling), and the associated content location may be notified accordingly.
  • CS signaling (answer of call) is used to halt multimedia content transfer, which uses e.g. a packet switched connection.
  • the multimedia information data is comprised in a user-to-user information (UUI) container as part of a direct transfer access part (DTAP) alerting message.
  • UUI containers and DTAP alerting messages are part of the common iunctioning of today's telecommunications networks.

  • the present invention also enables the calling party (first terminal 1) to provide the called party (second terminal 2) with a personal multimedia alert.
  • the method presented in the present invention is applied in the forwards direction, as shown in the exemplary embodiment depicted in Fig. 12.
  • the necessary additional data is included in the DTAP Setup by an application running in the first terminal 1 (e.g. IMS client 24).

  • the Personalized Call Alerting is placed on the B-party's call related home page.
  • a terminal application (either in the first terminal 1 or in the second terminal 2) may have the following enhancement.
  • an application in the first terminal 1 may prompt the user to take a picture and use that picture as personal multimedia alert to the called party (second terminal 2).
  • the application includes in the DTAP Setup message a reference to this picture (besides the IP address of the terminal 1).
  • the called party terminal 2 may then retrieve that picture during the alert, as described before.

Abstract

La présente invention concerne un procédé de fourniture de services d'accueil personnalisé (PGS) et un serveur (10) permettant d'offrir un accueil personnalisé sous la forme d'une séquence multimédia à un terminal (1; 2). Le serveur PGS (10) peut être connecté à un réseau de télécommunication, lequel établit une connexion par commutation de circuits entre au moins deux terminaux (1, 2) au moyen de la signalisation par commutation de circuits. Le serveur PGS (10) est conçu pour servir d'interface avec les unités du réseau (16, 18, 20) dans le réseau de télécommunication et pour ajouter des données d'information multimédia à la signalisation par commutation de circuits. Les données d'information multimédia permettent de transférer un contenu multimédia vers l'un des deux terminaux utilisateurs (1, 2).
