Abstract

A communications system includes a mobile computing device having a dynamic address and mobile web server software. A client-local proxy-server has an IP address to which a web client can reliably and consistently establish an internet connection. In response to receiving a request from the web client to access the mobile computing device, the client-local proxy-server acts as an intermediary opening up a communications path between the web client and the assigned address of the mobile computing device. The mobile computing device repeatedly registers the current version of its address with the client-local proxy-server. The mobile computing device and proxy-server software require only targeted configuration changes to perform the disclosed intermediary routing operations.

Claims

1. A method of accessing a device having an assigned address, comprising:

storing the assigned address in a memory location;

receiving at a client-local proxy-server a request to access the device;

said request comprising a device identifier that uniquely identifies the device; and

in response to said request to access the device, identifying the device'"'"'s stored address based on said device identifier, said proxy-server acting as an intermediary to establish a data path between a sender of said request and said device, based on said stored address.

2. The method of claim 1 further comprising:

said assigned address comprises a dynamically assigned address; and

receiving and storing in said memory location an updated dynamically assigned address.

3. The method of claim 2, wherein said device identifier comprises a telephone number, a Mobile ID Number, an International Mobile Subscriber Identity or an International Mobile Equipment Identity.

4. The method of claim 1 wherein said client-local proxy-server comprises a TCP/IP proxy server.

5. The method of claim 1 wherein:

said client-local proxy-server comprises a URL having a static address; and

said request is received at said URL.

6. The method of claim 1 wherein:

said device comprises a mobile device having web server software; and

said data path comprises a client-server session.

7. A method comprising:

receiving at a device an assigned address that identifies a virtual location of said device on a network;

said device configured to transmit said received assigned address to a client-local proxy-server that receives a request to access said device from a web client;

said request comprising a device identifier that uniquely identifies said device; and

delivering data from said device to said web client over a communications path established by said client-local proxy-server using said assigned address to act as an intermediary between said web client and said device.

8. The method of claim 7 comprising:

said assigned address comprises a dynamically assigned address; and

transmitting to said client-local proxy-server an updated assigned address in response to said assigned address changing.

9. The method of claim 7, wherein said device identifier comprises a telephone number, a Mobile ID Number, an International Mobile Subscriber Identity or an International Mobile Equipment Identity.

10. The method of claim 7 further comprising:

said device comprises a mobile device having web server software; and

said communications path comprises a client-server session.

11. An apparatus for opening a communications path to a device, the apparatus comprising:

a client-local proxy-server that receives an address assigned to the device and stores said assigned address in a memory location;

said client-local proxy-server including a URL that receives a request to access the device;

said request comprising a device identifier that uniquely identifies the device; and

said client-local proxy-server in response to said request to access the device, identifying the device'"'"'s stored address based on said device identifier, and acting as an intermediary to open a communications path between a sender of said request and said device, based on said stored assigned address.

12. The apparatus of claim 11 wherein:

said device comprises a mobile device having web server software; and

said communications path comprises a client-server session.

13. The apparatus of claim 11 wherein:

said client-local proxy-server comprises web proxy-server software; and

said web proxy-server software is configured to identify the device'"'"'s stored assigned address based on said device identifier, and open said communications path between said sender of said request and said stored assigned address.

14. A system comprising:

a device that receives an assigned address identifying a virtual location of said device on a network;

said device comprising commercially available and substantially non-proprietary mobile web server software configured to transmit said assigned address to a client-local proxy-server that receives requests to access said device from a web client;

said requests comprising a device identifier that uniquely identifies said device; and

said mobile web server software further configured to deliver data from said device to said web client over a communication link established by said client-local proxy-server acting as an intermediary between said web client and said device based on said assigned address.

15. The system of claim 14, wherein said mobile web server software is further configured to transmit to said client-local proxy-server an update of said assigned address in response to said assigned address changing.

16. The system of claim 15 wherein said mobile web server software is further configured to:

associate said device identifier with said assigned address; and

transmit said device identifier and said assigned address to said client-local proxy-server.

17. The system of claim 16 wherein said communication link comprises a client-server session.

18. The system of claim 16 wherein said web client comprises a remote web client this is remotely located from said client-local proxy-server.
