The message is then stored in the message store (130), translated in the translation unit (150) and delivered to the destination through the in/out interface (110) and an appropriate transport network (300).

Description

"METHOD AND DISPOSITION FOR THE HANDLING OF MULTIPLE MEDIA MESSAGES IN A TELECOMMUNICATION SYSTEM" BACKGROUND OF THE INVENTION The present invention relates to methods in a communication system that allows messages including types of multiple messages have been stored and delivered to and from a variety of types of terminals through a plurality of interconnecting networks. The invention also relates to an arrangement for carrying out these methods.

CURRENT STATE OF THE TECHNIQUE It is previously known a communication system through the US Patent Number A-4,837,798 wherein a single electronic mailbox can receive and store different types of messages, such as voice or data messages. The recipient of the message has a single point of contact with the system where all the messages can be scanned / viewed, which is pre-selected by the receiver. If necessary, - the communication system carries out the transfer of the medium from one medium to another. In addition, an individual message can be composed of parts that use different native media. U.S. Patent Number A-5, 333, 266 discloses a method and apparatus for integrating mail of a plurality of different types of media handling of mail servers such as text, voice, facsimile, video and image. Various interfaces of the terminal, e.g., computers or telephones, can be used to collect, generate and act on the message of any type of medium. For this purpose, the apparatus comprises transfer modules for the bi-directional transfer between speech and text and between the recognition of the optical character and the text. From the Patent Number EP-A-0, 662, 763 is known "an integrated electronic message system for storing and retrieving electronic messages of different types of data such as voice, video, text or facsimile." Electronic messages addressed to a specific destination are placed in a single electronic mailbox, regardless of the data type of the electronic message.Each message may consist of several message bodies, which contain parts of the message of different data types.When a stored message is retrieved from a true - endpoint device, the message format is adapted as much as possible to those device media classes - specific endpoint can reproduce. the endpoint device is a regular telephone message, the bodies representing sounds can be presented directly, the text bodies containing voice converted data and message bodies carrying video or image data are deleted. In the solution according to the American Patent Number A-4,837,798 the receiver only has a single point of contact with the communication system. The system is therefore unable to handle e.g., mobile users wandering from one point to another. The input messages are always delivered to a fault terminal regardless of whether or not the user is in it. The North American Patent suggests a distributed message transfer system that involves a message transfer module in each of the interconnected networks. All the message transfer modules keep a copy of each message sent. This solution consumes considerable resources that could be used for alternative purposes. The electronic message transfer system of Patent Number EP-A-0, 662, 763 only transfers information of the heading and the title. In addition, messages are always pre-moved, that is, if - the presentation capabilities in the current location of a user requires that a message be moved before the delivery of the message is directly transferred and stored centrally in the transferred format. Since the transfer takes place when the message is received and not when a message is currently retrieved, certain transfers may prove unnecessary. This is the case, for example, when a user before giving access to a certain message changes his terminal to a terminal that can give access to the message in its original format.

EXHIBITION OF THE INVENTION An object of the present invention therefore is to provide a common message storage which can be accessed not only from one but from multiple types of terminal and network. Another object of the present invention is to link the stored message to a user location database, which maintains a record of each current or last registered user location. A further object of the present invention is to minimize the overall need for message transfer due to the limited display capabilities of one or more of the user-specific terminals.

Still a further object of the present invention is to minimize the total need for message transfer due to the limited transmission capabilities of one or more of the specific interconnection telecommunication networks. These and other objects are satisfied by the present invention according to which the transfer is carried out in accordance with the data of the terminal type stored in the location database. The automatic transfer procedure is complemented by a dynamic dialogue between the user and the message system. The dynamic dialog provides the user with an opportunity to notify the system of any of the additional media capabilities that his terminal may have and / or may inform the system that his terminal can not handle a specific media format, but another variation of this format and / or to select an alternative terminal that may also have access to its current location and that is capable of presenting the multi-media message in a preferred format or formats. The message system of the present invention ensures that each multi-media message is delivered to the recipient of the intended message, regardless of its current location.

In addition, the message system according to the invention automatically detects the optimal transfer of the message to an alternative means, when the transfer of the message is necessary. According to a first aspect of the invention, when a multi-media message is addressed to a user in the message system, the input message is stored in a multi-media message storage. A first notification signal for this input message is diverted from an address manifested in the address field of the message to the message system. A second notification signal is then sent from the message system to a location provided by a stored address. Subsequent to the user being notified of the multiple input media message by the second notification signal, a connection is established between the user's location and the message system. This connection is established through the dynamic dialogue described above. All the parts of the multi-media message that they need and that can be moved to another media format in order to present themselves to the terminal of the current user, are moved accordingly. Translated parts and parts of the multi-media message that do not need move, they are finally transferred so they are presented to the user's terminal. If the presentation capabilities of the user's terminal make it necessary to exclude one or more parts of a certain multi-media message, this fact is preferably indicated to the user along with the presentation of the message. A method according to this first aspect of the invention is characterized herein by what is evident from claim 1. In accordance with a second aspect of the invention, when a user in the message system wishes to review, avoid or delete , that is, acting on a specific media message that is retained in the storage of multiple media messages, it contacts the message system from, an arbitrary terminal connected to any telecommunication network. After this, the presentation capabilities at the specific user's location are established through a dynamic dialogue between the user and the message system. Then, the multiple media message moved to an appropriate format possibly better for the given presentation capabilities, is delivered from the message system to the user through the aforementioned network. A method of compliance with this second aspect of the invention is characterized by what will be evident from claim 2. Naturally, the user is also provided with an opportunity to carry out any of the modifications of the content of the multi-media message and store an edited version of the message . Therefore, in accordance with a third aspect of the invention, a multi-media message is originated by a user in the message system in accordance with the following procedure. The user connects to the message system from any terminal. The terminal can be connected to any telecommunications network using arbitrary standard protocols. First, the multi-media message generation capabilities of the terminal are established through a dynamic dialogue between the user and the message system. Second, a multiple media message is created by the user and sent to the message system. Third, the message is stored in the storage of multiple media messages. Fourth, if the message or parts of the message need and can be translated into a format that is ideally suited to the presentation capabilities of the message provided by the transmission network to which the receiver is connected and by the protocol used by the transmission channel. messages that the message is delivering, this transfer takes place in the related portions of the message. Finally, the message or the transferred message is transmitted to the receiver. A method according to this third aspect of the invention is hereby characterized by what is evident from claim 6. A message sending system for carrying out the previously identified aspects of the invention comprises a message storage of multiple media wherein a copy of each message sent to or from the system is maintained, a transfer unit for converting each message sent and received in an appropriate message format possibly better for the presentation capabilities of the receiver's current terminal, a base of data that stores address and terminal data references for all users in the system and a control unit to control and coordinate the other units in the system. The message sending system in accordance with the invention is hereby characterized by what is evident from claim 10. Therefore, the proposed solution offers notification to a user when a multi-media message arrives, regardless of which in which network is located or if you have a subscription on this network or not. - A user may also provide access to his / her multiple media messages previously received from more than one terminal in a multiplicity of network environments. In addition, the invention provides multi-media message receivers with a large amount of multi-media information as possible, regardless of the type of terminal used. As the term indicates, a multi-media message may include more than one message format. The invention presents parts of the message of a multi-media message to a receiver in accordance with the following principle. First, present the largest possible data in its original format. Second, transfer the remaining data to a format adapted to the presentation capabilities of the user's terminal. Third, exclude the distant possible data of the message that is going to be presented. Preferably, the receiver is notified of any possible deletions of one or several parts of a certain multi media message due to limitations in the presentation capabilities of the current terminal of the receiver. Since the receiver always has an opportunity to decide and adjust the above definitions of the presentation capabilities of his current terminal in a dynamic dialog with the system, provides a guarantee that each multi-media message is optionally presented to its recipient.

DESCRIPTION OF THE FIGURES Figure 1 shows the message sending system of the invention interconnected with other communication systems; Figure 2 illustrates the method according to the invention when a multi-media message is addressed to a user in the suggested message delivery system; Figure 3 illustrates the method according to the invention when a user in the suggested message delivery system acts on a stored multiple media message; Figure 4 illustrates the method according to the invention, when a multi-media message originates from a user in the suggested message delivery system. The invention will now be described in further detail with the aid of the preferred embodiments and with reference to the accompanying drawings.

PREFERRED MODALITIES In Figure 1 there is shown a message sending system (100) according to one embodiment of the invention. The system (100) is interconnected with at least a first access network (200) and a second transport network (300). A user (u) in the system (100) uses the access network (200) to contact the system (100) through a terminal (400) when he wishes to originate a multiple media message or act on a media message multiple stored. The access network (200) is also used by the system (100) to deliver the users (u) the multiple media messages. The access network (200) and the transport network (300) can be any kind of communication network such as, eg, a PSPDN network (PSPDN = Public Switched Data Network) (210, 310), a CSPDN (CSPDN = Public Network of Switched Data in Circuit (210, 310), a TCP / IP network- (TCP / IP = Transmission Control Protocol / Internet Protocol) (220, 320), a GPRS network - (GPRS = General Packet Radio Service) (230, 330), a digital radiotelephone network (240, 340), an analog radio telephone network (250, 350), a PSTN (PSTN = Public Switched Telephone Network) (260, 360), an ISDN (Integrated Services Digital Network) (270, 370) or a B-ISDN (B-ISDN = broadband ISDN) (270, 370) .The terminal (400) may be any kind of terminal with a connection to at least one of the access networks (200) mentioned above. Therefore, the terminal (400) for example, can be, a desktop computer or a work station (410), a portable computer per battery (420) connected to a digital mobile phone through a PCMCIA card or equipped with a radio modem, a personal digital assistant, a personal intelligible communicator or a network-based knowledge assistant or a personal intelligible communicator (430), a digital or analogue mobile phone (440), a desk phone regular, a cordless telephone (450) or a facsimile machine (460). The sold message system (100) comprises an input / output interface (11-0) which is connected to the transport network (s) (300) and a user access interface (120) connected to the network (es) ) access (200). The system (100) further comprises a multimedia message store (130) wherein copies of all messages sent to and from the message sending system (100) are retained and a user location database (140). ) where the network address of each user (u) in the system (100) is recorded. A transfer unit (150) translates the messages from multiple media from at least a first media format to at least a second media format and the terminals of the originator and the recipient of a specific multi-media message have different message generation and different message presentation capabilities, e.g., due to the fact that they are all connected with separate networks that support different protocols. The transfer of the message may also be necessary if the originator and the receiver connect to the same xed but use different terminal types, such as e.g., a regular telephone (450) and a facsimile machine (460), both connected to the PSTN (250, 360). A control unit (160) controls and monitors all other units within the message sending system (100). Figure 2 illustrates the method according to the invention when a multi-media message (M) is directed (As) to a user (u) in the message sending system (1Q0). The multi-media message (M) can be anything from an ordinary telephone call on the PSTN to a multi-media mail message including hypertexts, voice messages, images and video sequences. In this example, assume that the user _ (u) has at least two subscriptions or network identities (Ai, A2, Aß) in one or more networks and / or network types. Each of these subscriptions or network identities (Al, A2, A8) are possible primary addresses for a message of multiple means (M) to the user (u), since the originator of the message (M) can direct the same to a destination identified by any of the known network identities or subscriptions (Ai, A2, As) for that user (u) ). The user (u) is now in a location (SLi) that has a first address (Al). When the user (u) registers either the address (Ai) of this location (SLi) manually in the message sending system (100) or originates a message from this location (R (A?)) Through the system of sending messages (100) of sending messages, a registration message (R (A?)) is sent to the system (100). The registration message (R (A?)) Comprising the identity of the user (U), the current address data (Al) and if necessary the information related to the type of terminal and the presentation capabilities of multiple means are sends through an access network (200) to a user access interface (120) in the system (100). The registration message (R (A?)) Is then stored in a user location database (140). When the multi-media message (M) addressed (As) to a location (SL8), where the user (u) has a subscription, is transmitted, an initial notification signal (Pl) is routed to this location (SLs) .

However, the notification signal (Pi) is deviated according to a piece of information linked to the user's identity (U) indicating that the user (u) is indicated elsewhere. This information is generated when the user (u) is deleted from the record of a specific location (SLe) and registered in another location (? Li). Notification deviation may occur either directly or after a predetermined non-response time. A signal (U, M) comprising the user's identity (U) and the multi-media message (M) is sent through a transport network (300) to an inward / outward interface (110) in the system (100) The user information (U) is passed to a control unit (160), which retrieves the location data (LD (A?)) For the user (u) from the location database (140), and the message (M) is stored in a storage of multiple media messages (130). This method is controlled by a first control signal (ci) from the control unit (160) to a storage of multiple media messages (130). The location data (LD (A?)) Is used by the system (100) when a notification signal (PL) is sent through the user access interface (12J0) and the access network (200) to the current location (SLi) of the user (u). The two directions (As and Al) of course they can be identical (As = Al) if the user (u) is now located in the address (As) associated with the input message (M). If the user (u) has been deleted from the system registry (100) and no new network identity has been registered, the notification signal (PL) is instead sent to a predefined fault address. After the user (u) has answered the notification signal (PL), a connection is established between the location (SLl) of the current user and the system (100). This connection allows a dynamic dialogue (D) between the user (u) and the system (100), where the presentation capabilities of the message in the location (SLl) of the user are established. The multi-media message (M) is not automatically adapted to a message format that is appropriate for the type of the user's present terminal (u) even when this would have been possible. The reason for this is that the user (u) can also have access to an alternative terminal whose address has not been registered in. the system (100) of the current user's terminal has better presentation capabilities than what appears from the type of terminal registered in the location database (140).

The user (u) e.g. You can have a facsimile / phone combination. If this equipment has not been registered as a facsimile machine and a voice message arrives, the user may not want the -message to be moved towards the text. Instead, you want it to be presented through the telephone device. Vice versa, if the terminal has been registered as a telephone and a fax message arrives, the user probably does not want the message to be transferred to a voice signal, but rather that it has been presented in the format of the original text. However, all the data of the multiple media message that can be presented directly by the user's registered terminal (u) is automatically transferred through the access interface (120) of the user and the access network (200) to the location current (SLl) of the user for presentation. When the display capabilities of the user terminal (u) have been verified, the multi-media message (M) is sent to a message transfer unit (150) for transfer of those parts of the message (M) that are needed and that can be translated into the format of the message that is intelligible through the user's terminal (u). The transfer instructions are included in a second control signal (C2) from the control unit (160) to the message transfer unit (150). A multi-media message (M ') comprising the parts of the original message (M) and / or the moved parts of the original message (M) to be presented to the user's terminal (u), is then sent to the Access interface (120) of the user. Then, the message (M ') transferred to the location of the current user (SL1) through the access network (200) and finally presented to the user (u). Figure 3 illustrates the method according to the invention when a user (u) acts on a multi-media message (M) that is stored in the multi-media message storage (130). Acting in a multi-media message (M) will be understood as being the recovery, editing and storage or deletion of a given message (M). A registration message (R (A3)) updates the address of the user (u) and the terminal data is sent to the system (100) during manual registration or after a first message has originated from a new location (L3) ) by the user (u). The registration message (R (A3)) is sent to the location database (140) through an access network (200) and the access interface _ (120) of the user. When the user (u) wishes to retrieve a specific multi-media message (M) from the storage of multiple media messages (130) it contacts the message delivery system (100) through the access network ( 200) and the access interface (120) of the user. A dynamic dialogue (D) between the user (u) and the control unit (160) in the system (100) establishes the presentation capabilities of the current user's terminal. The specific message (M) is then retrieved from the multi-media message storage (130) by means of a third control signal (c3) from the control unit (160) to the multi-media message storage (130) and it is sent to the message transfer unit (150) for transfer. The parts of the message (M) that need and can move to a format of the medium that can be presented intelligibly in the user's terminal (u) are moved to that format and the parts of the message that can be presented directly are passed through the unit (150) undisturbed. The transfer instructions are included in the second signal being controlled (C2) sent from the control unit (160) to the message transfer unit (150). A multi-media message (M ') comprising the parts of the original message (M) and / or the moved parts of the original message (M) to be presented to the user's terminal (u) is sent to the access interface of the user (120) and transferred to the user's location (L3) through the access network (200). The user (u) reviews the message (m ') and edits the desired parts thereof. An edited multiple media message (m ') is sent back to the system (100) for storage. He The edited message (m ') is transported to the message transfer unit (150) through the access network (200) and the user access interface (120). The transfer unit (150) translates the multi-media message (m ') to its original format (m), that is, the message (M) was originally stored and passes the message (m) to the storage of the media message multiple (130). This procedure is carried out by means of a fourth control signal (c4) from the control unit (160) to the message transfer unit (150). The method according to the invention when a multi-media message (M) originates from a user (u) in the message sending system (100) is illustrated in Figure 4. As stated above, a message from register (R (As)) that updates the user's address (u) and the terminal data is sent to the system (100) when the user (u) manually registers and makes this information or after a first multiple media message is has originated from a new location (Ls) by the user (u). The registration message (R (A5)) is sent to the location database (140) through an access network (200) and the user access interface (120). When the user (u) wishes to create a multi-media message (M) from the location (Ls) through the message sending system (100), is contacted -with the system for sending messages (100) through the access network (200) and the user access interface (120). A dynamic dialogue (D) between the user (u) and the control unit (160) establishes the capabilities or message creation of the current user's terminal. A multi-media message (M) is then generated in the user's terminal and sent together with an address of -destination (Ax) to the system (1Q0), through the access network (200) and the access interface of the user (120). The message (M) is transferred to the storage of multiple media messages (130) and the destination address (Ax) is passed to the control unit (160). The control unit (160) compares the format of the message provided by a source terminal and the format of the message used in the network to which the destination address (Ax) belongs. If it is necessary to transfer some or all of the parts of the message (M), those parts of the message that need and can be moved to the message format intelligibly by the addresses are moved to this format in the unit (150) message transfer, those parts of the message (M) that do not need transfer pass unchanged through the transfer unit (150) and any other possible non-transferable parts of the message (M) are not sent from storing multiple media messages (130) to the transfer unit (150). However, if the multi-media message contains these non-transferable parts, the receiver is informed of the fact together with the message. The multi-media message (M '), comprising the parts of the original message (M) and / or the translated parts of the original message (M), is sent to the interface in / out (110). The address of the receiver (Ax) is sent by the control unit (160) and is associated with the message (M ') and ensures that the multi-media message (M') is transferred through a transport network (300) to the correct destination address (Ax). The aforementioned methods all reflect different aspects of the same concept of the invention with respect to the use of a multi-media message storage, a message transfer unit and a location-based database by which users can receive, create or originate and act -in the messages of multiple media independently of the location and telecommunication network.
