DETAILED DESCRIPTION
In addition to the drawings, further understanding of the object, construction, characteristics and functions of the invention, a detailed description with reference to the embodiments is given in the following. FIG 1 illustrates the client and server architecture in accordance with an embodiment of the present invention. The system involves a plurality of user devices, for instance, but not
limiting to IMS devices, owned by two users, Alice and Bob. In this example, Alice has two devices (500, 501), whereby at least one of her devices (500) has established a document communication session (DCS) with Bob's device (600) by means of the centralized IMS core using any access networks such as WiFi, WiMAX, 3G and the likes. The method used for the system involves several steps, in which the first is to send a request by at least one of the users, in this example is Alice, for Document Collaboration Application (DCAS) (15) to function as a proxy in performing actions such as, but not limiting to, seeking the other user's device which is Bob, a permission to establish DCS. Then the next step involves brokering for the information related to the respective session and device capabilities from Session Transferring Application Server (STAS) (20), as suitably seen in FIG 1. Subsequently, the shared document is transcoded to an image file which is viewable on different devices, in addition to synchronizing the content viewed across devices participating in a DCS.
Alice then is allowed to transfer an on- going DCS from the current active device (500) to at least one of her alternative devices (500, 501) through the interaction with STAS (20) and DCAS (15). The DCS is preferably transferred from a first IMS enabled device (500) to the second or alternative IMS enabled device (501).
FIG 2 shows the components involved in order to achieve the intended functions in accordance with a preferred embodiment of the present invention. The main components are a document viewer module (200), an action handler module (210), a document collaboration management module (DCM) (220) and a session management module (SM) (230). Peripheral components to aid the primary components as mentioned includes the VOIP application with session transfer module (280) and SIP module (250). These components are
suitably configured to be interconnected with the operating system module (260) and hardware module (270).
In accordance with the preferred embodiment of the present invention, the document viewer module (200) is configured to handle prefaces of GUI applications, provisioning of a file manager to retrieve document intended for sharing and interactions with the underlying action handler module (210).
Still referring to FIG 2, the action handler module (210) plays a major role in providing interface with the document viewer (200) to the IMS services, these are the document DCM (220) and the SM (230). The action handler (210) is configured to translate the user's interaction captured through, but not limiting to, keystroke, mouse clicking or touch screen in document viewer (200) into suitable actions. In the preferred embodiment of the present invention, upon triggered by the upper application module, DCM (220) communicates with DCAS for the setup stage, provisioning and terminating of a DCS. The Session Management Module (230) is configured to communicate with STAS to conduct the procedures necessary for a session transfer to take the place. Further in the preferred embodiment of the present invention, the VOIP application (280) is configured to be part of the IMS-enabled device. Suitably with such arrangement, the user is granted with freedom to transfer either one of the session, i.e. DCS or voice call only.
FIG 3 shows the components for the Document Collaboration Application Server (15) in accordance with the preferred embodiment of the present invention. Accordingly, the server (15) interacts with IMS-enabled communication devices by means of MS core, and communicates with STAS (20) directly. In the first connection, with the IMS-enabled device, a series of SIP signaling is deployed while in the second connection, being the direct connection with STAS (20), normal TCP/UDP communication is involved.
The main steps involved in the DCAS (15) when a connection with a user device is established will be described hereinafter with reference to FIG 3. In accordance with the preferred embodiment of the present invention, the session router (30) intercepts a request from a user's device through the IMS core. From here, the session router (30) decides on the sequence of actions to be carried out, based on the request received from the user's device. Session router (30) then instructs the modules positioned at the upper layer for instance session manager (290), client proxy (40) and transcoder to perform their functionalities accordingly. In this process, the session router (30) plays an important role in broadcasting the transcoded document to devices participating in the DCS.
The session manager module (290) is responsible in retrieving information related to session and device capability from STAS (20), and storing them within a database. The client proxy (40) module serves to request the permission from the corresponding node's (CN) device to establish a DCS and thus broadcasting page control signals to devices. Transcoder (35) is a module that is configured to convert the document uploaded into at least one image file which is viewable on the communication devices, without requiring the installation of additional software or codec. In addition, the transcoder (35) is configured to resize the file to fit the smaller screen normally provided on user mobile or portable devices. Upon completion
of the necessary tasks, the session router (30) communicates with the respective users devices to response on their intended request.
The components and steps involved with respect to the overall view of the present invention in accordance with a preferred embodiment will be illustrated herein shortly, with reference to FIG 4.
In the preferred method, in the midst of conducting a VOIP call to the corresponding node, for instance Bob, Alice is able to initiate a concurrent DCS. This is achieved by pressing a predetermined key on the respective device, particularly on the keypad or keyboard or any task of the likes to send a request for establishing DCS from said device to the DCAS (15). Upon receipt of this request, on behalf of Alice, DCAS (15) proceeds to seek CN's permission to join the DCS. In the event that the CN (which in this case can be Bob's) accepts the request, DCAS (15) then proceeds to interact with STAS (20) in order to retrieve information from devices used by Alice and the said CN/Bob. Apart from this, DCAS (15) is configured to further obtain information on the device capabilities of the involved devices of Alice and CN/Bob from the STAS (20). Based on the information retrieved on the devices, DCAS (15) informs the active device currently used by Alice that DCS can be performed. The chosen document to the uploaded is delivered to DCAS (15) so as to perform transcoding. Based on the participating devices capabilities, the document is converted to image file of different sizes to fit each participating device. The transcoded document may be scaled to fit small screen devices, and to conserve bandwidth for sending images to devices. Subsequently, DCAS (15) then proceeds to broadcast the transcoded documents to all participating devices. Upon notified to initiate the slide presentation, Alice's active device informs STAS (20) that a DCS is established. For every control signal received from the
active device, DCAS (15) broadcoasts it to the CN's device, hence effectively synchronize the content viewed across every device. In addition, a control feedback is provided as a mechanism to Alice's active device to ensure that everyone is viewing the same content. In another preferred embodiment of the present invention, there is provided a session transfer of the DCS from the active device to an alternative device, as shown in FIG 5. To complete such transfer, the active device is configured to query STAS (20) for a list of alternative devices of which the DCS can be transferred to. After choosing the alternative device, the active device notifies DCAS (15) on the selected alternative device, in order for DCAS (15) to proceed with sending the transcoded document to the selected alternative device. At the same time, the STAS (20) is notified on the newly added alternative device so as to ensure that whenever a transition signal is sent out from the active device, the content viewed on the CN's device and alternative device will change accordingly. Upon completion of the respective presentation, active device notifies the DCAS (15) about the DCS termination. In response to this, the DCAS broadcasts the termination or teardown signal to both CN's device and alternative device. When received the teardown or termination signal, both devices send an acknowledgement back to DCAS (15) and accordingly terminate the DCS session. The DCAS (15) then proceeds to report the event to active device before freeing up the resources occupied by the DCS session. During this process, the active device informs STAS (20) about the DCS termination so that STAS (20) can perform corresponding updates on session information.
The present invention may be modified in light of the above teachings. It is therefore understood that, within the scope of the appended claims, the invention may be practiced otherwise than as specifically described.
