Abstract

The present invention installs an IP intranet functionality in a Mobile Switching Center for supporting wireless data and multimedia services within an operator community of interest. An IP network is introduced between a multimedia device and the Internet. The intranet provides a subnetwork and service context for wireless telco operators. Upon initiation of a service session by a multimedia terminal, the Mobile Switching Center presents the subscriber with an operator “intranet homepage” that serves as the primary navigator and launch pad for traversing the operator intranet or for launching a session on the Internet. If the initiating device is a voice only terminal, the Mobile Switching Center enables connection to another voice only terminal as usual.

Claims

1. A method for providing mobile-switching-centric intranet access to wireless devices within a given geographic location area uniquely served by a mobile switching center (MSC), said MSC establishing and switching connectivity between wireless devices within said given geographic location area and wireline network access points, said method comprising:

establishing packet-based communications between wireless devices within said given geographic location area and an intranet host server that includes processing and routing functionality for sharing information and data processing resources among wireless devices accessing said MSC, said establishing packet-based communications including;

responsive to receiving a device activation signal from a wireless device within said given geographic location area, determining whether said wireless device is a multimedia device; and

responsive to determining that said wireless device is a multimedia device,establishing a network connection between said wireless device and said intranet host server.

2. The method of claim 1, wherein said establishing a network connection between said wireless device and said intranet host server includes transmitting an internet protocol homepage maintained by said intranet host server to a browser application within said wireless device.

3. The method of claim 1, wherein said establishing a network connection between said wireless device and said intranet host server is performed only in response to determining that said wireless device is a multimedia device.

4. The method of claim 1, wherein said device activation signal is a power-on signal or a location area update signal.

5. The method of claim 1, wherein said MSC facilitates mobile handoff for wireless devices traveling to or from said given geographic location area from or to other geographic location areas served by other MSCs.

6. The method of claim 1, wherein said given geographic location area consists of a plurality of geographically contiguous mobile access areas.

7. The method of claim 6, wherein each of said mobile access areas is a cell within a cellular telephony system.

8. A mobile-switching-centric intranet system, comprising:

a mobile switching center (MSC) that provides switching connectivity between wireless devices within a given geographic location area uniquely associated with said MSC and wireline network access points;

an intranet hosted by a server communicatively coupled to said MSC, wherein said intranet enables packet-based communications between wireless devices within said given geographic location area and said intranet host server;

means responsive to receiving a device activation signal from a wireless device within said given geographic location area, for determining whether said wireless device is a multimedia device; and

means responsive to determining that said wireless device is a multimedia device, for establishing a network connection between said wireless device and said intranet host server.

9. The mobile-switching-centric intranet system of claim 8, wherein said means for establishing a network connection between said wireless device and said intranet host server includes means for sending an internet protocol homepage maintained by said intranet host server to a browser application within said wireless device.

10. The mobile-switching-centric system of claim 8, wherein said means for establishing a network connection between said wireless device and said intranet host server is enabled only in response to determining that said wireless device is a multimedia device.

11. The method of claim 8, wherein said device activation signal is a power-on signal or a location area update signal.

12. The mobile-switching-centric intranet system of claim 8, wherein said MSC facilitates mobile handoff for wireless devices traveling to or from said given geographic location area from or to other geographic location areas uniquely associated with other MSCs.

13. The mobile-switching-centric system of claim 8, wherein said at least one intranet host server includes processing and routing functionality for sharing information and data processing resources among wireless devices accessing said MSC.

14. The mobile-switching-centric system of claim 8, wherein said given geographic location area consists of a plurality of geographically contiguous mobile access areas.

15. The mobile-switching-centric system of claim 14, wherein each of said mobile access areas is a cell within a cellular telephony system.

16. A program product for providing mobile-switching-centric intranet access to wireless devices within a given geographic location area uniquely served by a mobile switching center (MSC), said MSC establishing and switching connectivity between wireless devices within said given geographic location area and wireline network access points, said program product comprising:

instruction means for establishing packet-based communications between wireless devices within said given geographic location area and an intranet host server that includes processing and routing functionality for sharing information and data processing resources among wireless devices accessing said MSC, said establishing packet-based communications including;

instruction means responsive to receiving a device activation signal from a wireless device within said given geographic location area, for determining whether said wireless device is a multimedia device; and

instruction means for responsive to determining that said wireless device is a multimedia device, establishing a network connection between said wireless device and said intranet host server.

17. The program product of claim 16, wherein said establishing a network connection between said wireless device and said intranet host server includes transmitting an internet protocol homepage maintained by said intranet host server to a browser application within said wireless device.

18. The program product of claim 16, wherein said establishing a network connection between said wireless device and said intranet host server is performed only in response to determining that said wireless device is a multimedia device.

19. The program product of claim 16, wherein said device activation signal is a power-on signal or a location area update signal.

20. The program product of claim 16, wherein said MSC facilitates mobile handoff for wireless devices traveling to or from said given geographic location area from or to other geographic location areas served by other MSCs.

21. The program product of claim 16, wherein said given geographic location area consists of a plurality of geographically contiguous mobile access areas.

22. The program product of claim 21, wherein each of said mobile access areas is a cell within a cellular telephony system.
