Abstract

A user'"'"'s access patterns are accounted for in deciding to switch between a plurality of wireless networks 204, 206. A method according to one embodiment of the present invention includes monitoring a location of a wireless communication device 202 within a region serviced by a first wireless communication network 204 and second region serviced by a second wireless communication network 206. The first and second region have an overlapping region which could be serviced by both networks. The future location of the wireless communication device 202 within the first and second regions is predicted based on the monitoring of the previous locations of the wireless communication device 202. When the wireless communication device 202 is detected as being within the overlapping region, the system determines whether to transfer an active connection between the wireless communication device 202 and one of the networks to the other network. In one embodiment, past patterns of usage of the wireless communication 202 device within the first and second region are identified and used to predict a future location based on the past pattern. In another embodiment, a calender of predetermined time-location associations is input into a controller 203 associated with the wireless communication device 202 and the prediction is based on an actual location and current time being compared with the values input into the calender.

Claims

1. A method for controlling the hand-off of a wireless communication device between a first wireless communication network and a second wireless communication network, comprising:

compiling a database of past time-location associations of said wireless communication device within a first region serviced by said first wireless communication network and a second region serviced by said second wireless communication network, wherein said first region and said second region have a predetermined overlapping region;

detecting when said wireless communication device is located within said predetermined overlapping region during an active connection;

predicting, responsive to said detecting, a future location of said wireless communication device within said first region or said second region during said active connection, wherein said predicting uses said database of past time-location associations;

transferring, based on a result of said predicting, said active connection between said one of said first or second wireless communication networks to the other of said first or second wireless communication networks when said wireless communication device is detected as being within said predetermined overlapping region.

2. The method of claim 1, comprising monitoring past patterns of usage of said wireless communication device in said first region or said second region prior to said compiling.

3. The method of claim 2, wherein said monitoring comprises detecting an active connection between said wireless communication device and a switching office of one of said first and second wireless communication networks.

4. The method of claim 3, wherein said monitoring further comprises determining a time of a making of said active connection.

5. The method of claim 4, wherein said monitoring comprises determining a location of said wireless communication device during said making of said active connection.

6. The method of claim 1, further comprising storing a calendar of predetermined times and locations of said wireless communication device in said first region or said second region prior to said compiling said database.

7. The method of claim 1, further comprising storing a calendar of predetermined time-location associations of said wireless communication device in said first region or said second region prior to said compiling said database.

8. The method of claim 7, wherein said predicting comprises comparing an actual location and current time with said time-location associations.

9. The method of claim 1, wherein said predicting comprises comparing an actual location and time with said time-location associations stored in said database.

10. The method of claim 1, wherein said predicting comprises determining whether said wireless communication device is likely to repeatedly be in transit between said first region and said second region.

11. The method of claim 10, wherein said transferring comprises transferring said active connection responsive to determining that said wireless communication device is not likely to repeatedly be in transit between said first region and said second region.

12. A wireless telecommunication system, comprising:

a first wireless network providing service over a first predetermined region and comprising a first switching office;

a second wireless network providing service over a second predetermined region and comprising a second switching office, wherein said first predetermined region and said second predetermined region overlap in a third predetermined region; and

wherein said second switching office comprises;

a memory unit configured to store a database of past time-location associations related to a past presence of said wireless communication device in either said first predetermined region or said second predetermined region; and

a wireless switching control unit coupled to said database, and configured to access said database when said wireless communication device is detected within said third predetermined region and to transfer an active call between said first or second wireless networks based on said past time-location associations.

13. The wireless telecommunication system of claim 12, wherein said database comprises a calendar of a schedule of time-locations associations of a user of said wireless communication device.

14. The wireless telecommunication system of claim 13, wherein said first wireless network communicates over a first wireless protocol, and said second wireless network communicates via a second wireless protocol.

15. The wireless telecommunication system of claim 14, wherein said second wireless network is a private telecommunication system.

16. The wireless telecommunication system of claim 12, wherein said database comprises a calendar of a schedule of a user of said wireless communication device and a record of past time-location associations related to past usages of said wireless communication device.

17. The wireless telecommunication system of claim 16, wherein said first wireless network is a public telecommunication system.

18. The wireless telecommunication system of claim 12, wherein said wireless communication device includes a smart switching controller configured to transmit a location of said wireless communication device to said wireless switching control unit.

19. The wireless telecommunication system of claim 12, wherein said wireless communication device comprises a first transceiver configured to communicate over said first wireless network and a second transceiver configured to communicate on said second wireless network.

20. A method for controlling the interface of a wireless communication device handset between and a first wireless communication network and a second wireless communication network, comprising:

monitoring a location of said wireless communication device handset within a first region serviced by said first wireless communication network and a second region serviced by said second wireless communication network, wherein said first region and said second region have a predetermined overlapping region;

identifying, responsive to said monitoring, past patterns of usage of said wireless communication device handset within said first region or said second region;

predicting, based on said past patterns of usage, a future pattern of usage of said wireless communication device handset within said first region or said second region; and

determining, responsive to said predicting, whether to transfer an active connection between said wireless communication device handset and one of said first or second wireless communication networks to the other of said first or second wireless communication networks when said wireless communication device handset is located within said predetermined overlapping region.
