Definitions

  • the present invention generally relates to the field of information handling systems, and particularly to network access via information handling systems.
  • the general purpose information handling system includes a large variety of hardware and software components for handling a wide number of tasks or functions regardless of how often the information handling system is called upon to implement those tasks or functions. Thus, many hardware or software components remain dormant for extended periods of time until, occasionally, they are activated to execute a requested task. For many situations and for many users, the convenience of the ability to perform a great variety of tasks and functions when called upon far outweighed the fact that the modules and hardware that executed those tasks and functions may remain unused for extended periods of time.
  • This model for an information handling system was particularly beneficial for general purpose applications such as desktop computer systems designed for home or office use where the information handling system was intended to be used for more than one task or function.
  • information handling systems are increasingly being utilized for special-purpose applications rather than for general purpose applications.
  • information handling systems are being designed to optimally implement a smaller set of tasks or functions in order to achieve reduced size, complexity and costs, while at the same time retaining at least some level of general purposeness such that at least one or two additional functions may be later added to the information handling system if necessary in order to extend the useful life of the system and to provide a level or flexibility.
  • This type of special purpose information handling system is often referred to as an "appliance" or “box” in order to connote that, while still retaining a certain level of general purposeness, the information handling system is optimized (i.e. stripped down) to perform only a few core functions and that some of the "bells and whistles" of a general purpose information handling system are not included because they have been deemed to be unnecessary for most users.
  • PDA personal digital assistant
  • the PDA operating system may be stored in a read-only memory chip or flash type memory chip rather than on a hard disk drive such that the boot time for the PDA is significantly reduced compared to the boot time for a general purpose information handling system having a more complex, full featured operating system booted from a hard disk drive.
  • a modem may be included with the PDA or added as an upgrade such that the PDA may couple to the Internet for web browsing and electronic mail functions with software that has fewer features than comparable software found in general purpose information handling systems.
  • appliances or boxes include set top boxes for providing television tuning features with Internet browsing features, game console boxes having Internet capabilities such that two remotely located users may play against each other via the Internet, ovens that have Internet capability such that a user may program the oven from a remote location to have dinner ready when the user arrives home, etc.
  • appliances, boxes and personal computers are being coupled together via local networks.
  • local networks In a business environment such local networks are typically referred to as intranets, whereas in a consumer environment such local networks are referred to as home networks.
  • home network environment for example, multiple appliances, boxes and at least one personal computer are coupled together via a home network, and a common connection to a world wide network such as the Internet via a modem is shared by all of the devices.
  • an appliance or box type of information handling system will access the network (e.g., the Internet) using its reduced set of functions and thus operate at a first level of functionality.
  • the network e.g., the Internet
  • the system will be required to execute a task or function that the system will not be able to execute.
  • the application required to execute the task may only be included on a general purpose information handling system that is capable of operating at a second level of functionality. It would therefore be desirable to provide a system and method for accessing the network at a multileveled, multi-tiered functionality.
  • the present invention is directed to a system for providing multi-tiered network access.
  • the system includes a first device for accessing a network wherein the first device provides a first level of functionality, a second device for accessing a network wherein the second device provides a second level of functionality, a means such as a local or home network for coupling the first device with the second device, and a means such as a modem or router for providing network access to either of the first device or the second device wherein the first device accesses the network at the first level of functionality and, when required by the first device, the second device accesses the network at the second level of functionality.
  • the present invention is further directed to a method for providing multi-tiered access to a network.
  • the method includes steps for accessing a network with a first device wherein the first device provides a first level of functionality, receiving information to be processed from the network, determining whether the first device is capable of processing the received information, in the event the first device is determined to be incapable of processing the received information, activating a second device wherein the second device provides a second level of functionality, and processing the information with the second device.

Abstract

L'invention concerne un système qui permet un accès à multiples paliers à un réseau tel qu'Internet. Un premier dispositif tel qu'un appareil ou un boîtier présentant un premier niveau inférieur de fonctionnalité peut avoir accès au réseau et reçoit un contenu de ce réseau. Lorsqu'il est déterminé que le premier dispositif peut traiter le contenu, un utilisateur est avisé de l'événement, et si nécessaire, un deuxième dispositif tel qu'un système informatique complet présentant un deuxième niveau supérieur de fonctionnalité est activé pour traiter le contenu. L'application requise pour traiter le contenu est lancée sur le deuxième dispositif, et le contenu est traité par l'application lancée. Lorsque le deuxième dispositif traite le contenu, le premier dispositif peut servir de mandataire entre les dispositifs d'E/S et le deuxième dispositif, ce qui permet à un utilisateur de contrôler le deuxième dispositif par l'intermédiaire du premier dispositif. Les premier et deuxième dispositifs peuvent être couplés par une connexion directe comme une connexion de bus série universel, ou les dispositifs peuvent être couplés par un réseau familial tel qu'un réseau conforme à la norme HomePNA. La sortie du deuxième dispositif peut être fournie au premier dispositif et visualisée sur un affichage couplé au premier dispositif.
