Abstract

A virtual network is configured in a communication system in such a manner that the virtual network is not required to have associated therewith any particular physical home location, or more generally any dedicated arrangement of physical network infrastructure elements. The communication system includes a communication network, such as a wireless network or the Internet, connectable to one or more user communication elements. Information is received from a given one of the communication elements indicating association of the given communication element with a particular virtual network, and responsive to the received information the virtual network is configured to include the given communication element. The virtual network may be comprised entirely of remote users. Emulated data network and voice network functionality may be provided to those users without requiring their corresponding entity to have a physical home location for data network and voice network elements, or any particular dedicated arrangement of such physical network infrastructure elements.

Claims

1. A method for configuring a virtual network in a communication system, the communication system comprising a communication network connectable to one or more user communication elements, the method comprising the steps of:

receiving from a given one of the communication elements information indicating association of the given communication element with a particular virtual network; and

responsive to the received information, configuring the virtual network to include the given communication element;

wherein the virtual network is configured in such a manner that it is not required to have any particular dedicated arrangement of physical network infrastructure elements associated therewith.

2. The method of claim 1 wherein the virtual network is configured in such a manner that it is not required to have any particular physical home location associated therewith

3. The method of claim 1 wherein the communication network comprises a wireless network connectable to one or more wireless communication elements.

4. The method of claim 1 wherein the communication network comprises a wired network connectable to one or more wired communication elements.

5. The method of claim 3 wherein the one or more wireless communication elements comprise at least one hub-based wireless communication element.

6. The method of claim 5 wherein the hub-based wireless communication element comprises a wireless module for establishing a communication connection between an associated hub and the wireless network.

7. The method of claim 5 wherein the hub-based wireless communication element comprises a plurality of ports each connectable to a corresponding one of a plurality of user processing devices.

8. The method of claim 1 wherein the virtual network is allocatable to an entity that comprises only remote users each associated with at least a corresponding one of the communication elements.

9. The method of claim 1 wherein the virtual network is configured to include the given communication element under the control of one or more servers associated with the communication network.

10. The method of claim 9 wherein the one or more servers store state and configuration information characterizing the virtual network.

11. The method of claim 9 wherein the one or more servers are operated by a network service provider which provides the communication network.

12. The method of claim 9 wherein the one or more servers are operated by an entity unrelated to a network service provider which provides the communication network.

13. The method of claim 9 wherein the one or more servers are associated with a virtual network service provider and further have associated therewith an access element which determines if the given communication element has generated a packet directed to an element of the virtual network and if so generates a corresponding signal to the one or more servers.

14. The method of claim 1 wherein the system is configured to support a plurality of virtual networks at a given point in time, each of at least a subset of the plurality of virtual networks including one or more of the communication elements.

15. The method of claim 14 wherein at least one of the plurality of virtual networks is provided under the control of a first network service provider, and at least one other of the plurality of virtual networks is provided under the control of a second network service provider associated with the system and unrelated to the first network service provider, the first and second network service providers sharing at least a portion of a physical network infrastructure of the system.

16. The method of claim 1 wherein a set of accessible virtual network resources are defined for the given communication element as part of an initial setup or other configuration process for the virtual network.

17. The method of claim 16 wherein the system provides an interface whereby the set of accessible network resources may be periodically altered at least in part under user control.

18. The method of claim 1 wherein the received information comprises at least one of:

(i) a connection request;

(ii) at least a portion of a network address of the given communication element; and

(iii) a signal generated based at least in part on a network address associated with a packet transmitted by the given communication element.

19. An apparatus for configuring a virtual network in a communication system, the communication system comprising a communication network connectable to one or more user communication elements, the apparatus comprising:

a processor-based device comprising a processor coupled to a memory, the device being configurable to receive from a given one of the communication elements information indicating association of the given communication element with a particular virtual network, and, responsive to the received information, to configure the virtual network to include the given communication element;

wherein the virtual network is configured in such a manner that it is not required to have any particular dedicated arrangement of physical network infrastructure elements associated therewith.

20. A machine-readable medium storing one or more programs for use in configuring a virtual network in a communication system, the communication system comprising a communication network connectable to one or more user communication elements, wherein the one or more programs when executed by a processor implement the steps of:

receiving from a given one of the communication elements information indicating association of the given communication element with a particular virtual network; and

responsive to the received information, configuring the virtual network to include the given communication element;

wherein the virtual network is configured in such a manner that it is not required to have any particular dedicated arrangement of physical network infrastructure elements associated therewith.
