Example embodiments relate to conference call systems and methods, and in particular to authenticating participants of a conference call.
During a conference call, voice-communication connections are typically made between communication devices such as telephones or mobile phones.
The participants of a conference call are sometimes loosely defined wherein original invitees can forward invitations to others who can then participate. With only rudimentary security procedures such as a conference call dial-in number and assess code almost anyone from any location can be a conference call participant.
Another difficulty is that the primary details of a conference call, including the date, the invited participants and/or the subject matter may be an issue of security. Forwarding such details of a pending conference call could be considered a security violation.
Other difficulties with existing teleconferencing systems will be apparent to those skilled in the art in view of the detailed description below.
Reference will now be made, by way of example, to the accompanying drawings which show example embodiments, and in which:
Similar reference numerals may have been used in different figures to denote similar components.
Some example embodiments generally relate to a conference call system which authenticates the device which is attempting to participate in the call.
In one aspect, there is provided a method for authenticating client devices from a conference call server, wherein the conference call server includes a memory for storing conference call scheduling information with respect to scheduled conference call sessions, wherein the conference call server is in communication with an enterprise server. The method includes receiving in the conference call server a communication from a client device with respect to a scheduled conference call session, and determining whether the client device is associated with the enterprise server, and if so authenticating the client device with respect to the scheduled conference call session.
In yet another aspect, there is provided a non-transitory computer readable medium having recorded thereon statements and instructions for execution by one or more devices for authenticating client devices for a conference call, the statements and instructions comprising code means for performing the method.
In yet another aspect, there is provided a conference call server including a memory for storing conference call scheduling information with respect to a scheduled conference call session, a communications subsystem for communicating with an enterprise server and a client device, and a controller. The controller is configured for: receiving a communication from the client device with respect to the scheduled conference call session, and determining whether the client device is associated with the enterprise server, and if so authenticating the client device with respect to the scheduled conference call session.
In another aspect, there is generally provided an interface on a device which replaces the raw information in the message or calendar body with an address link to a conference call server. Selection of the address initiates authentication of the device, for requesting receipt of at least some of the remaining conference call details, such as subject, date, recurrence, web information (e.g. join-now links), or audio information (e.g. dial-in numbers, access codes).
In another aspect, there is provided a mobile communication device including a controller; a communications subsystem for communicating with a conference call server, wherein the conference call server includes a memory for storing conference call scheduling information with respect to a conference call session, the communications subsystem being configured for receiving a message containing sender information and an address link with respect to the scheduled conference call session; a display for displaying an interface including an option to select the address link; and wherein, in response to selection of the option through the interface, the controller controls the communications subsystem to send a communication to the conference call server, the communication being for receiving from the conference call server in response at least some of any remaining conference call scheduling information including information for connecting to the scheduled conference call session.
Example embodiments relate to the control and management of conference call communications. Although reference may be made to “calls” and “talk” in the description of example embodiments below, it will be appreciated that some of the described systems and methods may be applicable to session-based communications in general and not limited to voice calls. Reference to calls may for example include shared data (e.g. presentation content) as well as media sessions which may for example include video and/or audio.
Reference is now made to
The enterprise network 20 may be connected, often through a firewall 22, to a wide area network (WAN) 30, such as the Internet. The enterprise network 20 may also be connected to a public switched telephone network (PSTN) 40 via direct inward dialing (DID) trunks or primary rate interface (PRI) trunks.
The enterprise network 20 may also communicate with a public land mobile network (PLMN) 50, which may also be referred to as a wireless wide area network (WWAN) or, in some cases, a cellular network. The connection with the PLMN 50 may be made via a relay 26, as understood in the art.
The enterprise network 20 may also provide a wireless local area network (WLAN) 32a featuring wireless access points. Other WLANs 32 may exist outside the enterprise network 20. For example, WLAN 32b may be connected to WAN 30.
The system 10 may include a number of enterprise-associated mobile devices 11 (only one shown). The mobile devices 11 may include devices equipped with communications modules for cellular communication through the PLMN 50, mobile devices equipped for Wi-Fi communications over one of the WLANs 32, or dual-mode devices capable of both cellular and data communications. WLANs 32 may be configured in accordance with one of the IEEE 802.11 specifications.
It will be understood that the mobile devices 11 include one or more radio transceivers and associated processing hardware and software to enable wireless communications with the PLMN 50 and/or one of the WLANs 32. In various embodiments, the PLMN 50 and mobile devices 11 may be configured to operate in compliance with any one or more of a number of wireless protocols, including GSM, GPRS, CDMA, EDGE, UMTS, EvDO, HSPA, 3GPP, or a variety of others. It will be appreciated that the mobile device 11 may roam within the PLMN 50 and across PLMNs, in known manner, as the user moves. In some instances, the dual-mode mobile devices 11 and/or the enterprise network 20 are configured to facilitate roaming between the PLMN 50 and a WLAN 32, and are thus capable of seamlessly transferring sessions (such as voice calls) from a connection with the cellular interface of the dual-mode device 11 to the WLAN 32 interface of the dual-mode device 11, and vice versa.
The mobile devices 11 may be various types of communication devices. Such mobile devices 11 may include “Class A” devices, which are able to function continuously as dual-mode devices, capable of both media and data communications. Mobile devices 11 may also include “non-Class A” devices, which may function as dual-mode devices for initialization or prior to connection with the enterprise communications platform 14, but may lose data functionality once a media session (e.g., voice call) is established. The enterprise network 20 may also include additional client devices which are voice-only or media-only devices, which may be digital or analog for communication with the PSTN, and which may not have data capabilities (herein referred to as “voice-only” or “media-only” devices). In other embodiments, the mobile devices 11 may include any suitable client device configured with the communications functionality described herein, and may for example include computer devices, relays, proxies, gateways and any appropriate User Agents (as defined in SIP).
The enterprise network 20 typically includes a number of networked servers, computers, and other devices. For example, the enterprise network 20 may connect one or more desktop or laptop computers 15 (one shown). The connection may be wired or wireless in some embodiments. The enterprise network 20 may also connect to one or more digital telephone sets 17 (one shown).
The enterprise network 20 may include one or more mail servers, such as mail server 24, for coordinating the transmission, storage, and receipt of electronic messages for client devices operating within the enterprise network 20. Typical mail servers include the Microsoft Exchange Server™ and the IBM Lotus Domino™ server. Each user within the enterprise typically has at least one user account within the enterprise network 20. Associated with each user account is message address information, such as an e-mail address. Messages addressed to a user message address are stored on the enterprise network 20 in the mail server 24. The messages may be retrieved by the user using a messaging application, such as an e-mail client application. The messaging application may be operating on a user's computer 15 connected to the enterprise network 20 within the enterprise. In some embodiments, the user may be permitted to access stored messages using a remote computer, for example at another location via the WAN 30 using a VPN connection. Using the messaging application, the user may also compose and send messages addressed to others, within or outside the enterprise network 20. The messaging application causes the mail server 24 to send a composed message to the addressee, often via the WAN 30.
The relay 26 serves to route messages received over the PLMN 50 from the mobile device 11 to the corresponding enterprise network 20. The relay 26 also pushes messages from the enterprise network 20 to the mobile device 11 via the PLMN 50.
The enterprise network 20 also includes an enterprise server 12. Generally, the enterprise server 12 is configured to collectively serve the needs of the enterprise network 20, for example to provide and/or synchronize messaging, contacts and calendaring information between servers, desktop workstations 15, and mobile devices 11. Together with the relay 26, the enterprise server 12 functions to redirect or relay incoming e-mail messages addressed to a user's e-mail address within the enterprise network 20 to the user's mobile device 11 and to relay incoming e-mail messages composed and sent via the mobile device 11 out to the intended recipients within the WAN 30 or elsewhere. The enterprise server 12 and relay 26 together facilitate “push” e-mail service for the mobile device 11 enabling the user to send and receive e-mail messages using the mobile device 11 as though the user were connected to an e-mail client within the enterprise network 20 using the user's enterprise-related e-mail address, for example on computer 15.
As is typical in many enterprises, the enterprise network 20 includes a Private Branch eXchange (although in various embodiments the PBX may be a standard PBX or an IP-PBX, for simplicity the description below uses the term PBX to refer to both) 16 having a connection with the PSTN 40 for routing incoming and outgoing voice calls for the enterprise. The PBX 16 is connected to the PSTN 40 via DID trunks or PRI trunks, for example. The PBX 16 may use ISDN signaling protocols for setting up and tearing down circuit-switched connections through the PSTN 40 and related signaling and communications. In some embodiments, the PBX 16 may be connected to one or more conventional analog telephones 19. The PBX 16 is also connected to the enterprise network 20 and, through it, to telephone terminal devices, such as digital telephone sets 17, softphones operating on computers 15, etc. Within the enterprise, each individual may have an associated extension number, sometimes referred to as a PNP (private numbering plan), or direct dial phone number. Calls outgoing from the PBX 16 to the PSTN 40 or incoming from the PSTN 40 to the PBX 16 are typically circuit-switched calls. Within the enterprise, e.g. between the PBX 16 and terminal devices, voice calls are often packet-switched calls, for example Voice-over-IP (VoIP) calls.
The enterprise network 20 may further include a Service Management Platform (SMP) 18 for performing some aspects of messaging or session control, like call control and advanced call processing features. The SMP 18 may, in some cases, also perform some media handling. Collectively the SMP 18 and PBX 16 may be referred to as the enterprise communications platform, generally designated 14. It will be appreciated that the enterprise communications platform 14 and, in particular, the SMP 18, is implemented on one or more servers having suitable communications interfaces for connecting to and communicating with the PBX 16 and/or DID/PRI trunks. Although the SMP 18 may be implemented on a stand-alone server, it will be appreciated that it may be implemented into an existing control agent/server as a logical software component. As will be described below, the SMP 18 may be implemented as a multi-layer platform.
The enterprise communications platform 14 implements the switching to connect session legs and may provide the conversion between, for example, a circuit-switched call and a VoIP call, or to connect legs of other media sessions. In some embodiments, in the context of voice calls the enterprise communications platform 14 provides a number of additional functions including automated attendant, interactive voice response (IVR), call forwarding, voice mail, etc. It may also implement certain usage restrictions on enterprise users, such as blocking international calls or 1-900 calls. In many embodiments, Session Initiation Protocol (SIP) may be used to set-up, manage, and terminate media sessions for voice calls. Other protocols may also be employed by the enterprise communications platform 14, for example, Web Services, Computer Telephony Integration (CTI) protocol, Session Initiation Protocol for Instant Messaging and Presence Leveraging Extensions (SIMPLE), and various custom Application Programming Interfaces (APIs), as will be described in greater detail below.
One of the functions of the enterprise communications platform 14 is to extend the features of enterprise telephony to the mobile devices 11. For example, the enterprise communications platform 14 may allow the mobile device 11 to perform functions akin to those normally available on a standard office telephone, such as the digital telephone set 17 or analog telephone set 15. Example features may include direct extension dialing, enterprise voice mail, conferencing, call transfer, call park, etc.
Reference is now made to
In this embodiment, the SMP 18 assumes control over both call processing and the media itself. This architecture may be referred to as “First Party Call Control”. Many of the media handling functions normally implemented by the PBX 16 are handled by the SMP 18 in this architecture. Incoming calls addressed to any extension or direct dial number within the enterprise, for example, are always first routed to the SMP 18. Thereafter, a call leg is established from the SMP 18 to the called party within the enterprise, and the two legs are bridged. Accordingly, the SMP 18 includes a digital trunk interface 62 and a digital signal processing (DSP) conferencing bridge 64. The DSP conferencing bridge 64 performs the bridging of calls for implementation of various call features, such as conferencing, call transfer, etc. The digital trunk interface 62 may be implemented as a plurality of telephonic cards, e.g. Intel Dialogic cards, interconnected by a bus and operating under the control of a processor. The digital trunk interface 62 may also be partly implemented using a processor module such as, for example, a Host Media Processing (HMP) processor.
The SMP 18 may include various scripts 66 for managing call processing. The scripts 66 are implemented as software modules, routines, functions, etc., stored in non-volatile memory and executed by the processor of the SMP 18. The scripts 66 may implement call flow logic, business logic, user preferences, call service processes, and various feature applications.
The call control server 18 is coupled to the PBX 16, for example through the LAN, enabling packet-based communications and, more specifically, IP-based communications. In one embodiment, communications between the PBX 16 and the call control server 18 are carried out in accordance with SIP. In other words, the call control server 18 uses SIP-based communications to manage the set up, tear down, and control of media handled by the PBX 16. In one example embodiment, the call control server 18 may employ a communications protocol conforming to the ECMA-269 or ECMA-323 standards for Computer Supported Telecommunications Applications (CSTA).
The SIP server 72 interacts with the media server 76 using SIP-based media handling commands. For example, the SIP server 72 and media server 76 may communicate using Media Server Markup Language (MSML) as defined in IETF document Saleem A., “Media Server Markup Language”, Internet Draft, draft-saleem-msml-07, Aug. 7, 2008. The media server 76 may be configured to perform Host Media Processing (HMP).
Other architectures or configurations for the enterprise communications system 14 will be appreciated by those ordinarily skilled in the art.
Reference is now made to
Specifically, the protocol layer 34 preferably includes protocols which allow media to be controlled separate from data. For example, the protocol layer 34 can include, among other things, a Session Initiation Protocol or SIP 80, a Web Services protocol 82, an Application Programming Interface or API 84, a Computer Telephony Integration protocol or CTI 86, and a Session Initiation Protocol for Instant Messaging and Presence Leveraging Extensions or SIMPLE protocol 88. It is contemplated that the interface protocols 80-88 are plug-ins that can interface directly with corresponding servers in the enterprise network 20, which will be further described below.
Although SIP 80 may be utilized, it is appreciated that the system 10 can operate using the above disclosed or additional protocols. As known by those of ordinary skill in the art, SIP is the IETF (Internet Engineering Task Force) standard for multimedia session management, and more specifically is an application-layer control protocol for establishing, maintaining, modifying and terminating multimedia sessions between two or more endpoints. As further known by those of ordinary skill in the art, the SIP protocol 80 includes two interfaces for signaling: SIP-Trunk (hereinafter referred to as “SIP-T”) and SIP-Line (hereinafter referred to as “SIP-L”). Specifically, the SIP-T interface is utilized when the endpoint is a non-specific entity or not registered (i.e., when communicating between two network entities). In contrast, the SIP-L interface is utilized when the endpoint is registered (i.e., when dialing to a specific extension). SIP is defined in J. Rosenberg et al., “RFC 3261-Session Initiation Protocol” (June 2002), the contents of which are herein incorporated by reference.
The SMP 18 also includes a plurality of enablers, among other things, a VoIP enabler 90, a Fixed Mobile Convergence or FMC enabler 92, a conference services enabler 94, a presence enabler 96 and an Instant Messaging or IM enabler 98. Each of the enablers 90-98 are used by corresponding services in the services layer 36 that combine one or more of the enablers. Each of the applications in the application layer 38 is then combined with one or more of the services to perform the desired application. For example, a phone call service may use the VoIP or PBX enabler, and an emergency response application may use the phone call service, an Instant Messenger service, a video call service, and email service and/or a conference service.
The application layer 38 may include a conference services application 63 that, together with the conference services enabler 94, enables multiple communication devices (including desk telephones and personal computers) to participate in a conference call through use of a centralized conference server 55. As seen in
Example conference call systems and methods in accordance with example embodiments will now be described, referring now to
The enterprise communications platform 14 and the associated conference server 55 may be used for generally executing conference call functions. As described above, in example embodiments, the enterprise communications platform 14 may include or be coupled to the media server 76 (
Referring still to
In some example embodiments, the media sessions may be facilitated by the enterprise communications platform 14 by way of Real-time Transport Protocol (RTP) media sessions, and may include voice calls, video calls, circuit-switched calls or VoIP calls. In order to generate or establish a conference call session, the enterprise communications platform 14 connects or links at least some of the call legs of each media session 126. The particular methods and processes for connecting of media sessions 126 into a conference call session would be understood by those skilled in the art, which may for example be implemented by media shuffling or SDP (Session Description Protocol) media shuffling, etc.
In some example embodiments, a data connection (e.g. the same data connection as used by the control sessions 124) can be further used to provide additional data sharing between mobile devices 11. For example, during a conference call, the host mobile device 11a may provide or transfer a data file to the remaining mobile devices 11. Data sharing may also include Web Services or sharing of presentation content.
Reference is now made to
The mobile device 11 includes a rigid case (not shown) housing the components of the mobile device 11. The internal components of the mobile device 11 may, for example, be constructed on a printed circuit board (PCB). The description of the mobile device 11 herein mentions a number of specific components and subsystems. Although these components and subsystems may be realized as discrete elements, the functions of the components and subsystems may also be realized by integrating, combining, or packaging one or more elements in any suitable fashion. The mobile device 11 includes a controller comprising at least one processor 240 (such as a microprocessor) which controls the overall operation of the mobile device 11. The processor 240 interacts with device subsystems such as a wireless communication subsystem 211 for exchanging radio frequency signals with the wireless network (e.g. WAN 30 and/or PLMN 50) to perform communication functions. The processor 240 interacts with additional device subsystems including a display 204 such as a liquid crystal display (LCD) screen or any other appropriate display, input devices 206 such as a keyboard and control buttons, persistent memory 244, random access memory (RAM) 246, read only memory (ROM) 248, auxiliary input/output (I/O) subsystems 250, data port 252 such as a conventional serial data port or a Universal Serial Bus (USB) data port, speaker 256, microphone 258, short-range communication subsystem 262 (which may employ any appropriate a wireless (e.g., RF), optical, or other short range communications technology), and other device subsystems generally designated as 264. Some of the subsystems shown in
Display 204 may be realized as a touch-screen display in some embodiments. The touch-screen display may be constructed using a touch-sensitive input surface connected to an electronic controller and which overlays the visible element of display 204. The touch-sensitive overlay and the electronic controller provide a touch-sensitive input device and the processor 240 interacts with the touch-sensitive overlay via the electronic controller.
The wireless communication subsystem 211 includes one or more communication systems for communicating with wireless WAN base stations 30 and wireless LAN access points 32 within the wireless network. The particular design of the wireless communication subsystem 211 depends on the wireless network in which mobile device 11 is intended to operate. The mobile device 11 may send and receive communication signals over the wireless network after the required network registration or activation procedures have been completed.
The processor 240 operates under stored program control and executes software modules 221 stored in memory such as persistent memory 244 or ROM 248. The processor 240 can execute code means or instructions. ROM 248 may contain data, program instructions or both. Persistent memory 244 may contain data, program instructions or both, in some embodiments is rewritable under control of processor 240, and may be realized using any appropriate persistent memory technology, including EEPROM, EAROM, FLASH, and the like. As illustrated in FIG. 2, the software modules 221 comprise operating system software 223 and software applications 225.
Software modules 221 or parts thereof may be temporarily loaded into volatile memory such as the RAM 246. The RAM 246 is used for storing runtime data variables and other types of data or information, as will be apparent to those skilled in the art. Although specific functions are described for various types of memory, this is merely one example, and those skilled in the art will appreciate that a different assignment of functions to types of memory could also be used.
The software applications 225 may further include a range of applications, including, for example, an e-mail messaging application, address book, calendar application, notepad application, Internet browser application, voice communication (i.e., telephony) application, mapping application, or a media player application, or any combination thereof. Each of the software applications 225 may include layout information defining the placement of particular fields and graphic elements (e.g., text fields, input fields, icons, etc.) in the user interface (i.e., the display 204) according to the application.
In some embodiments, the auxiliary input/output (I/O) subsystems 250 may comprise an external communication link or interface, for example, an Ethernet connection. The auxiliary I/O subsystems 250 may further comprise one or more input devices, including a pointing or navigational tool such as a clickable trackball or scroll wheel or thumbwheel, or one or more output devices, including a mechanical transducer such as a vibrator for providing vibratory notifications in response to various events on the mobile device 11 (e.g., receipt of an electronic message or incoming phone call), or for other purposes such as haptic feedback (touch feedback).
In some embodiments, the mobile device 11 also includes one or more removable memory modules 230 (typically comprising FLASH memory) and one or more memory module interfaces 232. Among possible functions of the removable memory module 230 is to store information used to identify or authenticate a user or the user's account to wireless network (e.g. WAN 30 and/or PLMN 50). For example, in conjunction with certain types of wireless networks, including GSM and successor networks, the removable memory module 230 is referred to as a Subscriber Identity Module or SIM. The memory module 230 is inserted in or connected to the memory module interface 232 of the mobile device 11 in order to operate in conjunction with the wireless network.
The mobile device 11 stores data 227 in a persistent memory 244. In various embodiments, the data 227 includes service data comprising information required by the mobile device 11 to establish and maintain communication with the wireless network (e.g. WAN 30 and/or PLMN 50). The data 227 can also include, for example, scheduling and connection information for connecting to a scheduled call.
The mobile device 11 also includes a battery 238 which furnishes energy for operating the mobile device 11. The battery may be coupled to the electrical circuitry of mobile device 11 through a battery interface 236, which may manage such functions as charging the battery from an external power source (not shown) and the distribution of energy to various loads within or connected to the mobile device 11. Short-range communication subsystem 262 is an additional optional component which provides for communication between the mobile device 11 and different systems or devices, which need not necessarily be similar devices. For example, the short-range communication subsystem 262 may include an infrared device and associated circuits and components, or a wireless bus protocol compliant communication mechanism such as a BLUETOOTH communication module to provide for communication with similarly-enabled systems and devices.
A predetermined set of applications that control basic device operations, including data and possibly voice communication applications will normally be installed on the mobile device 11 during or after manufacture. Additional applications and/or upgrades to the operating system software 223 or software applications 225 may also be loaded onto the mobile device 11 through the wireless network (e.g. WAN 30 and/or PLMN 50), the auxiliary I/O subsystem 250, the data port 252, the short-range communication subsystem 262, or other suitable subsystem such as 264. The downloaded programs or code modules may be permanently installed, for example, written into the program memory (e.g., the persistent memory 244), or written into and executed from the RAM 246 for execution by the processor 240 at runtime.
The mobile device 11 may provide two principal modes of communication: a data communication mode and an optional voice communication mode. In the data communication mode, a received data signal such as a text message, an e-mail message, Web page download, or an image file will be processed by the wireless communication subsystem 211 and input to the processor 240 for further processing. For example, a downloaded Web page may be further processed by a browser application or an e-mail message may be processed by an e-mail message messaging application and output to the display 204. A user of the mobile device 11 may also compose data items, such as e-mail messages, for example, using the input devices in conjunction with the display 204. These composed items may be transmitted through the wireless communication subsystem 211 over the wireless network (e.g. WAN 30 and/or PLMN 50). In the voice communication mode, the mobile device 11 provides telephony functions and operates as a typical cellular phone.
In some existing conventional conferencing system, the use of PIN numbers or passcodes is solely used to determine authentication of participants.
This can have limited effectiveness for securing a conference call. In some other conventional systems, a host-designated “whitelist” of participants may also be provided to further restrict who enters the conference call by giving each participant a different passcode.
In some example embodiments, there is generally provided a system which can provide an additional layer of protection by authenticating the device (rather than the participant individual) at the enterprise level. Specifically, it is recognized herein that conference calls could be secured by determining whether the client devices are associated with an enterprise.
Referring briefly to
Reference is now made to
Still referring to
As shown in
At the time of the scheduled conference call, the enterprise communications platform 14 may contact each of the devices 11 to join the media sessions together. In example embodiments, the devices 11 may also dial or link into the enterprise communications platform 14 using dialing or address link information received during scheduling. In some traditional systems, any participant merely having the access code (for dial-in) or passwords (for address link) would be able to access the conference call, which could pose a security threat to the enterprise communications platform 14. Example embodiments herein provide additional authentication by identifying the actual client device 11, as an additional layer of security.
As shown in
Referring now to the participant icons 310, in the example shown, the user interface 300 is displayed on the host device 11a, indicated as “You-Host” as shown in icon 310b. Another participant icon 310a can be designated as the leader device 11, typically for the participant individual who will be doing the majority of the speaking, for example “John-Leader” as shown. The remaining participant icons 310c, 310d represent additional participant devices 11 (“Sally” and “David”, respectively, as shown). Contact information such as e-mail address or phone number for the participants can be pre-stored in association with the participant names (or can be manually entered, as appropriate). The status of each participant icon 310 can also be shown, for example, as Accepted, Tentative, or Declined.
As shown in
Generally, in some example embodiments, as part of the conference call session scheduling process, after the conference call scheduling information is configured by the host device 11a, the enterprise communications platform 14 subsequently communicates with each device 11 for inviting to the scheduled conference call and for provisioning at least some of the conference call scheduling information. Each device 11 has an option to Accept, Decline, or Tentative. If the device 11 selects Accept, this means that the device 11 will participate in the scheduled conference call. If the device 11 selects Decline, for example, the host device 11a is notified by the enterprise communications platform 14 that the scheduled conference call has been declined by the particular device 11. The notification may be made by phone call, data message, email, etc. If the host device 11a Declines, then the entire scheduled conference call may be cancelled and the other devices 11 notified accordingly. If the device 11 selects Tentative, then the enterprise communications platform 14 notifies the host device 11a accordingly.
Thus, reference is now made to
The invitation message 402 may be received as an e-mail message designating the participant's e-mail address, but can also be in other forms such as short message service (SMS), SIP message, instant messaging, or calendar invite. Note that, in other example embodiments, the message 402 may alternatively be received directly or indirectly from the host device 11a, rather than from the enterprise communications platform 14.
As shown on the interface 400, a number of response options 406 may be selected in order to respond to the invitation message 402. As shown, the response options 406 include Accept, Tentative, or Decline, as described above. Upon selection, the response is sent to the enterprise communications platform 14. In further example embodiments, selection of the Accept option may result in the details of the invitation message 402 being stored in a calendar application of the device 11. As shown, the response options 406 can also include an option to Forward 414 to a new participant client device. In some example embodiments, the Forward 414 function can be restricted depending on whether the new participant client device is permitted to join the conference call.
As shown in
As can be appreciated, in some example embodiments the address link 408 identifies the enterprise communications platform 14 as well as the scheduled conference call session, and can include a Uniform Resource Locator (URL), a Uniform Resource Identifier (URI), or other suitable address.
Specific implementations of authenticating a client device 11 in accordance with some example embodiments will now be described, referring now to
In example embodiments, the enterprise communications platform 14 includes a memory for storing conference call scheduling information with respect to a scheduled conference call session. The enterprise communications platform 14 can also include a communications subsystem for communicating with the enterprise server 12. As mentioned above, the enterprise server 12 may contain a registry of client devices 11 and the associated phone numbers, e-mail address, persistent device identifiers and/or related user information such as user name and corporate title. Generally, client devices 11 which are identified in the registry are considered secure and can therefore be authenticated with respect to a conference call. Further, the persistent device identifiers and e-mail are known to be unique to the client devices 11 when registered with the enterprise server 12.
At step 505, the enterprise communications platform 14 sends an invitation message to the client device 11. The invitation message 402 can include conference call scheduling information, for example the fields 404 described above and as displayed in
At step 510, at the time of the scheduled conference call, the enterprise communications platform 14 receives a communication from the client device 11 with respect to the call. The communication can be triggered by selection of the address link 408 (
At step 515, the enterprise communications platform 14 determines whether the client device 11 is associated with the enterprise server 12, by sending a request for authentication to the enterprise server 12. In response, the enterprise server 12 verifies the authentication of the client device, for example by checking the registry. At step 520, the enterprise server 12 sends a response to the enterprise communications platform 14 on whether the client device 11 is to be authenticated.
At this stage (steps 515 and 520), the enterprise communications platform 14 can further authenticate the client device 11 by checking a “whitelist” as contained in the stored conference call scheduling information. The “whitelist” can contain a list of eligible participants and associated devices 11 to the conference call, as designated by the host device 11a. For example, the list can be in the form of e-mail addresses or participant individual names, which are correlated with the persistent device identifiers of the client device 11.
The enterprise communications platform 14 can now authenticate the client device 11 with respect to the scheduled conference call session. At step 525, the enterprise communications platform 14 sends a response to the client device 11 that it is authorized to join the conference call session. At step 530, if authentication is successful, the enterprise communications platform 14 establishes a conference call session with the device 11. This typically involves establishing media session legs with other participant devices 11 and connecting the media session legs together.

The interface 600 can also include response options 606, including a Forward 614 response for forwarding the invitation message 602 to another participant device. If the present invitation message 602 is forwarded to another participant device, a similar interface 600 would be displayed on that device. Selection of the address link 610 from that device would result in requesting authentication from that participant device.
In some example embodiments, the enterprise communications platform 14 can further maintain a host-designated whitelist of authorized participants who may be granted access to the conference call scheduling information. If the invitation message is forwarded to someone not on the list they would not have access to the conference call scheduling information and could not participate in the call. The enterprise communications platform 14 may also store in the memory a log which stores and tracks those participant devices which have attempted to access the information, along with whether those devices were granted authorization.

Upon selection of the address link 710 through the interface 700, the device 11 send a communication to the enterprise communications platform 14. In response, if the device 11 is authenticated, the device 11 can receive at least some of any remaining conference call scheduling information. Upon receiving the information, the device 10 can display the interface 700 with the content in the subject fields populated (e.g., similar to as shown in

At step 815, the enterprise communications platform 14 determines whether the client device 11 is associated with the enterprise server 12, by sending a request for authentication to the enterprise server 12. In response, the enterprise server 12 verifies the authentication of the client device, for example by checking the registry. At step 820, the enterprise server 12 sends a response to the enterprise communications platform 14 on whether the client device 11 is to be authenticated.
At this stage (steps 815 and 820), enterprise communications platform 14 can further authenticate the client device 11 by checking a “whitelist” as contained in the stored conference call scheduling information. The “whitelist” can contain a list of eligible participants to the conference call. For example, the list can be in the form of e-mail addresses or participant individual names, which are correlated with the persistent device identifiers of the client device 11.
The enterprise communications platform 14 can now authenticate the client device 11 with respect to the scheduled conference call session. At step 825, the enterprise communications platform 14 sends a response to the client device 11 along with at least some of any remaining conference call scheduling information. This information can include information for connecting to the scheduled conference call session, for example Web Information or Audio Conference Information as shown in interface 700 (

At step 845, the enterprise communications platform 14 sends a response to the client device 11 that it is authorized to join the conference call session. At step 850, if authentication is successful, the enterprise communications platform 14 establishes a conference call session with the device 11. This typically involves establishing media session legs with other participant devices 11 and connecting the media session legs together.
