The present disclosure relates generally to systems and methods for provisioning and maintaining a network communications device. In particular, the present disclosure relates to devices and methods for providing enhanced information to Voice-over-IP (VoIP) subscribers.
In just a short time, VoIP has revolutionized the availability of affordable and advanced high-quality audio and visual communications. As VoIP has grown more popular, the size and complexity of service provider networks has increased immensely to handle the increased call volume and various service enhancements made possible by VoIP. As service (and/or equipment) provider networks grow, the task of provisioning service and maintaining it for a large customer base presents technological, logistical, and business challenges.
One example of prior art architecture for the remote (user or subscriber) end of a VoIP service provider network typically includes a connection device connected between a PSTN-based communication device (i.e. a typical telephone) and a packet-based network by which the VoIP service provider affects communication services. The connection device translates between analog signals required for the PSTN-based communication device and digital signals transmitted over the network. In some examples, the connection device is a stand-alone, dedicated device. In other examples, the connection device includes a wired or wireless router that accepts an incoming high speed packet network connection as input and provides one or more output ports for relaying such network signals to suitable end user equipment such as a computer and additional outputs for connection to a PSTN-based telephone. In each example, device status and other such network information is conveyed only by binary means. That is, typical the status information is conveyed by use of a few lights flashing on/off (i.e., LEDs) with minimal or technically descriptive abbreviations provided therebelow that only technically savvy individuals can interpret or understand. In some instances, there may be no markings at all.
Typically, when a communication failure occurs, (e.g., component failure, improper connection to the network or a power source, poor network traffic conditions and the like), extensive assistance must be provided to the end user by service personnel to diagnose the cause of the communication failure. These service personnel working remotely (e.g., over the phone, via an online “chat” session and the like) encounter difficulties when trying to properly diagnose the technical issues based on the performance issues as described by an end user (including which lights may or may not be illuminated on the communication device). In the frequent case that these symptoms or descriptions are incomplete or inaccurate, time and other resources are wasted in attempting to provide a solution to the problem.
Additionally, traditional communication devices are usually manufactured in ordinary rectangular shapes which are generally unappealing and lack a flair for design or visual impact. Accordingly, such existing-shaped communication devices are placed or otherwise installed underneath home office furniture, on the floor or otherwise generally out of sight so as to reduce clutter and undesirable visual appeal. As a result it is difficult to access the communication device to read the device status indicators and not generally possible to successfully display supplementary information to the user/subscriber that may be desirable. In view of at least these two factors, there is a lack of information, understanding and aesthetics that greatly reduces the potential enjoyment of the overall broadband telephone experience.
Accordingly, there is a need in industry for technological solutions to improve and simplify end user experience in the setup, use and further exploitation of connection devices, especially those used for VoIP, and VoIP services.
The present invention generally relates to a method and apparatus for information conveyance in an end user device of a packet-based communication service where the end user device is connected to a PSTN-based communication device. The method includes the steps of detecting a power up condition of the end user device connected to the PSTN-based communication device, detecting a packet-based network connection, retrieving an end user profile from the packet-based communication service attempting a communication registration operation and displaying one or more non-binary type messages at the end user device regarding the status of the communication service. The end user profile contains IP configuration information and the registration operation may be performed via SIP. The one or more messages for display is provided in the end user profile or delivered via a SIP NOTIFY message.
The apparatus for enhanced information conveyance includes a main body having at least one local area packet network connection means, at least one wide area packet network connection means and at least one non-packet network connection means for connection of a PSTN-based communication device and a display panel body adapted to display information regarding the status of the communication service in a non-binary manner. The display panel adaptation may be a display screen, one or more function buttons and a combination of such elements. The apparatus may have articulation means between the main body and display panel body for providing freedom of movement therebetween. The articulation means may be a hinge assembly, a set of telescoping members, a gimbal assembly and wireless means. In a preferred embodiment, the main body and the display panel body and integral with each other. The display panel body enhanced information conveyance means is responsive to communication service status messages from the packet-based communication service and those status messages are selected from messages included in the end user profile and messages provided by SIP messaging. Additionally, the display panel body enhanced information conveyance means is responsive to user-based requests to the packet-based communication service and such requests are selected from changing system features or apparatus settings associated with the end user device, reviewing call logs associated with the end user device, reviewing a status of user communication channels and inquiring about general system information.
Various aspects of the present disclosure will be or become apparent to one with skill in the art by reference to the following detailed description when considered in connection with the accompanying exemplary non-limiting embodiments, wherein:
One aspect of the present disclosure includes an apparatus for communicating a status of a communications device in a packet-based communication network and/or the packet-based communication network itself in a non-binary manner. In one embodiment of the invention, the packet-based communication network is a VoIP network that establishes voice communication sessions according to the Session Initiation Protocol (SIP). Session Initiation Protocol (SIP) is used to establish subscriber calls (into or out of the packed-based network and within the packet-based network to another subscriber). It was developed by the Internet Engineering Task Force (IETF) and published in 2002 as RFC 3261 which is herein incorporated by reference. SIP messages are exchanged between a VoIP service provider (via one or more database and proxy servers) and one or more end users (via a network terminal adapter (TA)) to establish the communication session. However, in instances where the communication session cannot be established, the subject invention includes means for providing enhanced information (i.e., beyond blinking lights) to facilitate troubleshooting the cause of the uninitiated session. Such means is also capable of displaying information regarding installation of the communication device and enhanced features as described in greater detail below.

The memory 604 is coupled to the CPU 602. The memory 604, or computer-readable medium, may be one or more of readily available memory such as random access memory (RAM), read only memory (ROM), floppy disk, hard disk, flash memory or any other form of digital storage, local or remote. The support circuits 606 are coupled to the CPU 602 for supporting the processor in a conventional manner. These circuits include cache, power supplies, clock circuits, input/output circuitry and subsystems, and the like. A software routine 612, when executed by the CPU 602, causes the controller 600 to perform processes of the present invention and is generally stored in the memory 604. The software routine 612 may also be stored and/or executed by a second CPU (not shown) that is remotely located from the hardware being controlled by the CPU 602.
The software routine 612 is executed when a preferred method of enhanced messaging in accordance with the subject invention is desired. The software routine 612, when executed by the CPU 602, transforms the general purpose computer into a specific purpose computer (controller) 600 that controls interaction between the communication device and the service provider and other similar actions. Although the process of the present invention is discussed as being implemented as a software routine, some of the method steps that are disclosed therein may be performed in hardware as well as by the software controller. As such, the invention may be implemented in software as executed upon a computer system, in hardware as an application specific integrated circuit or other type of hardware implementation, or a combination of software and hardware. The software routine 612 of the present invention is capable of being executed on computer operating systems including but not limited to Microsoft Windows 98, Microsoft Windows XP, Apple OS X, Linux and eCos. Similarly, the software routine 612 of the present invention is capable of being performed using CPU architectures including but not limited to Apple Power PC, Intel x86, Sun service provider agentRC, Intel ARM and MIPS.
In one embodiment of the invention, enhanced information is conveyed to the communication device from the service provider. Conveyance of the enhanced information is executed by one selected from the group consisting of the information being embedded in a device profile that is downloaded to the communication device and the information being embedded in a SIP NOTIFY message. Those skilled in the art of packet-based communication systems are familiar with the Session Initial Protocol (SIP) and the various messages including NOTIFY and such information has been referenced earlier in the specification. Once the enhanced information is conveyed, a portion or one or more software routines 612 performs the necessary steps to display the enhanced information on the display 106. For example, the communication device may request the information (in the form of an updated device profile) or be given the information upon expiration of a polling period, power up condition or as part of a NOTIFY message. The information is then temporarily stored (i.e., in memory 604 while processing occurs to prepare the information for display.
An LCD Controller thread 708 subscribes to specific events from an Event Framework 710 and maintains state information for Power-up states, Network states and Call states. It provides notification of state changes after appropriate filtering to a Display Thread 712. Based on the state, the Display Thread 712 calls the corresponding method within Display Controller classes 716 in a Display Controller 714 to display appropriate messages. The Display Thread 712 accepts event notification from the LCD Controller thread 708, a Keypad Driver Thread 718 and some events from the Event Framework 710. It calls the corresponding method within the Display Controller classes 716 to provide the event enumerations, which the Display Controller 714 uses to display appropriate messages on the LCD 706/106.
The Display Controller 714 runs in the context of the Display Thread 712. It accepts filtered events from the Display Thread 712. The Display Controller 714 also implements the User Menu Classes 716b and the Call History Classes 716a. When a keypad event is received, it results in state transitions in the User Menu Classes 716b and display of the appropriate menu. When a call state event is received (for example incoming call with a calling party identifier), the Display Controller 714 displays the corresponding message on the LCD 706/106 (in this case, the Caller ID). The Display Controller 714 also manages the icons. Since the ownership of the LCD 706/106 is always with the Display Controller 714, it prioritizes display of error messages over menu or informational messages. It may also block certain messages if it is displaying critical error messages.
In particular, the priority scheme and corresponding behavior implemented by the Display Controller 714 is as follows:
After all the power up messages from the LCD Controller, it displays the Default message (from a downloaded device profile).
In case of an Error message from the LCD, it displays the error message indefinitely. It also slowly blinks the backlight between low and high intensity in this condition.
If the user navigates into the user menu when an Error message is being displayed, the backlight changes to the intensity that was selected by the user (or the default intensity if it was after power up). When the user exits the user menu, it displays the Error message again (with the backlight blinking) if the error condition is persisting. If the error condition has cleared up, then it displays the Default message with the backlight at the intensity that was selected by the user (or the default intensity if it was after power up).
Warning or informational messages (such as Caller ID) will be displayed for some time (˜10 secs), and then the Default Message is displayed.
It may be emphasized that the above-described embodiments, particularly any “preferred” embodiments, are merely possible examples of implementations, merely set forth for a clear understanding of the principles of the disclosure. Many variations and modifications may be made to the above-described embodiments of the disclosure without departing substantially from the spirit and principles of the disclosure. All such modifications and variations are intended to be included herein within the scope of this disclosure and the present disclosure and protected by the following claims.
This application claims priority to U.S. Provisional Patent Application Ser. No. 60/934,650, filed Jun. 15, 2007, which is incorporated by reference herein in its entirety.
