It should be noted that, through the above scenario, it is possible to also browse other types of attachments to the MPM, such as pre-generated business card information, pre-generated voice-clips, Icons or pictures. The possibility to browse certain items (such as pictures) may depend on the capabilities of the cellular phone to display such items.
  • FIG 3a illustrates an alternative means of retrieving MPMs, by using SMS enabled handsets, as follows:
  • a subscriber receives a MPM message, by first receiving the SMS part, and can read and manipulate it just like a regular SMS.
  • Application server 153 obtains MPM text data from the main database 155.
  • Application server 153 sends MPM data SMS-based MPM data to the handset of subscriber B 110-2, via SMSC 130 and data interface 152.
  • the MPM data contains a text message and an internal (database) reference denoting the voice part of the MPM.
  • the MPM data part (i.e. the regular SMS) is presented on the mobile station. Within the message there is a textual indication, like "please reply with 'P' to hear voice attachment".
  • Subscriber B 110-2 replies by SMS, and types, for example letter P for "Play”.
  • System 100 calls the subscriber B 110-2 via VI 151 and MSC 120 so that the user can listen to the voice message.
  • Voice interface 151 requests the MPM voice file by message ID, from the voice database 154.
  • Voice interface 151 obtains the MPM voice file from the voice database 154 .
  • Voice interface 151 plays the voice file to subscriber B 110-2 through MSC 120.
  • the subscriber can also manipulate the message (e.g. back, fast-forward, etc.) using DTMF based directions.
  • An additional scenario is the retrieving of MPMs using a phone with WML browser or equivalent. This can be enabled according to the following scheme:
  • Subscriber B 110-2 receives the MPM message through a system triggered WAP session (from the WAP Gateway 140), and is first presented with the SMS text part, and can read and manipulate it just like a regular SMS. There is also a special sign (e.g. Icon) denoting the presence of an attached voice message.
  • a system triggered WAP session from the WAP Gateway 140
  • Icon denoting the presence of an attached voice message.
  • the subscriber may request to hear the attached voice message, through choosing the relevant option. If this option is chosen, the WAP session may be disconnected, or suspended, in order to setup a voice session, in case where the WAP protocol does not have the ability to maintain a WAP session (over a circuit switched data channel) and a voice session in parallel.
  • Making voice calls from a WAP session is executed using WTA (defined above).
  • the voice message is played through the phone.
  • the subscriber can also manipulate the message (e.g. back, fast-forward, etc.), using DTMF based directions.
  • the system again triggers a WAP session, only if the WAP session was previously disconnected or suspended, towards the cellular-phone, and the session is restored to the point of the previous disconnection/suspension.
  • the subscriber can further manipulate it through options like: save, delete, reply to subscriber A 110-1, transfer to another subscriber, with an option to also append his/her own MPM (the appending is done just like the composition of a new MPM).
  • Subscriber B can have several MPMs in his/her personal inbox (stored on the server) and can re-browse them and their attachments.
  • a cellular-phone with WML (or equivalent) support can render and present on the screen of the cellular-phone the bitmap of Icons or pictures, provided that these files can be converted by the system to a WBMP representation that is supported by the WML-Browser.
  • FIG. 4 illustrates the depositing of MPMs over SMS enabled handset (without STK), as follows:
  • Subscriber A 110-1 enters a MPM by typing a short message over the cellular phone Keypad, just as he/she would type an SMS message. Upon submitting the message to the system, subscriber A 110-1 also denotes the cellular number of subscriber B 110-2 (optionally, the name of a distribution list containing more than one subscriber, as facilitated by the cellular phone distribution-list mechanism (sometimes referredTo as "groups"), or through an external distribution list, kept on the system). Subscriber 110-1 may also enter a special notation that will denote his/her will to attach a voice attachment to the SMS.
  • This notation can, for example, be contained as a prefix or suffix in the SMS text, or can be a prefix to subscriber B's cellular number (or to each subscriber in the group).
  • the user may enter in a notation such as "!X" or any other notation which can be interpreted and used by the system.
  • the cellular operator gateways for example the SMSC 130 are able to route the relevant data via SMS to the system 100.
  • SMS is forwarded through SMSC 130 and data interface 152 to application server 153 of system 100.
  • Application server 153 stores the SMS message in the system main database 155.
  • SMS message is sent from the application server 130, via data interface 152 and SMSC 130, and is received by subscriber A 110-1, with text such as "please dial *5544 to record attachment” or "Press Send twice to record”(in which case the cell-phone dials the originator number in the SMS message, which is for example, also *5544).
  • Subscriber A 110-1 calls back to the specified number. By requesting to dial the number (e.g. *5544), which is a common feature of practically any regular cellular phone capable of receiving SMS messages, subscriber A 110-1 creates a voice connection though MSC 120 to voice interface 151, and subscriber 110-1 is prompted to record the voice attachment.

  • the steps, as can be seen in Figure 5, are as follows:
  • Subscriber A 110-1 enters a MPM by typing a short message over the cellular phone Keypad, in a special WML-Browser based screen, such a "deposit" page (which can be obtained by establishing a WAP session), just as he/she would type an SMS message.

  • the user can use the MPVM client interface on the handset to record a voice message and send it to another user.
  • the client application on the handset does not require the user to enter any typed text.
  • the procedure for executing MPVMs is therefore similar to the above operations for MPMs, except that in MPVM deposit procedure there are no stages for entering text, so the procedure is shorter.
  • Multiple destination MPM/MPVMs are means to create text and/or voice messages on mobile handsets, and then to transmit these messages to a group or groups of recipients.

  • MPM Post Call MPVM
  • the MPVM is similar to voice mail, except that instead of being stored in the voice mail server (database), it is stored on the application server of the present system, from where it can be accessed and managed. In this way, no service subscription is required (to define voicemail-box for instance), and more importantly, the message retrieval is done through text menus, which allow the user to access a specific message directly, by it's timestamp and sender identification. In the post call SMSV menu, the user can leave a voice message for the recipient.
  • the advantage over traditional voicemail is that all that is required by the user is a SMS interface - which is available to practically all mobile subscribers today.
