Abstract

A method and computer program for selecting an inactivity timeout interval for a mobile communications network include steps of: (a) receiving a direction of a last data transfer on a channel resource comprising a reverse link and a forward link allocated by the mobile communications network to a mobile station; (b) when the last data transfer is a forward data transfer, selecting a short inactivity timeout interval for releasing the reverse link wherein the short inactivity timeout interval corresponds to a latency of the mobile station; (c) when the last data transfer is a reverse data transfer, selecting a long inactivity timeout interval for releasing the forward link wherein the long inactivity timeout interval corresponds to a latency of a destination of the reverse data transfer; (d) when a new data transfer occurs between the mobile station and the destination before the selected inactivity timeout interval expires for the last data transfer, continuing from step (a), else (e) releasing the channel resource allocated to the mobile station.

Claims

1. A method of selecting an inactivity timeout interval for a mobile communications network comprising:

(a) receiving a direction of a last data transfer on a channel resource comprising a reverse link and a forward link allocated by the mobile communications network to a mobile station;

(b) when the last data transfer is a forward data transfer, selecting a short inactivity timeout interval for releasing the reverse link wherein the short inactivity timeout interval corresponds to a latency of the mobile station;

(c) when the last data transfer is a reverse data transfer, selecting a long inactivity timeout interval for releasing the forward link wherein the long inactivity timeout interval corresponds to a latency of a destination of the reverse data transfer;

(d) when a new data transfer occurs between the mobile station and the destination before the selected inactivity timeout interval expires for the last data transfer, continuing from step (a), else

(e) releasing the channel resource allocated to the mobile station when the selected inactivity timeout interval expires.

2. The method of claim 1 wherein the long inactivity timeout interval is about one second and the short inactivity timeout interval is about 100 milliseconds.

3. The method of claim 1 wherein the last data transfer is a non-streaming data transfer.

5. The method of claim 1 wherein the last data transfer is sent to the mobile station.

6. The method of claim 5 wherein the mobile station pings an Internet server after the last data transfer to initiate rapid release of the channel resource.

7. The method of claim 5 wherein the destination sends a kill switch packet to the mobile station to initiate rapid release of the channel resource.

8. The method of claim 1 wherein the channel resource comprises a radio link between the mobile station and the base station.

9. The method of claim 8 wherein the mobile communications network is one of Global Packet Radio Service, Global System Mobile, Code Division Multiple Access, Universal Mobile Telecommunications System, and other mobile communications systems that include mobile stations such as cellular telephones and wireless computer devices and equivalents thereof.

10. The method of claim 1 wherein the mobile station comprises one of a telephone and a computer device.

4. The method of claim 4 wherein the last data transfer comprises a TCP/IP data packet.

11. A computer program product for selecting an inactivity timeout interval for a mobile communications network comprising a medium for embodying a computer program for input to a computer and a computer program embodied in the medium for causing the computer to perform steps of:

(a) receiving a direction of a last data transfer on a channel resource comprising a reverse link and a forward link allocated by the mobile communications network to a mobile station;

(b) when the last data transfer is a forward data transfer, selecting a short inactivity timeout interval for releasing the reverse link wherein the short inactivity timeout interval corresponds to a latency of the mobile station;

(c) when the last data transfer is a reverse data transfer, selecting a long inactivity timeout interval for releasing the forward link wherein the long inactivity timeout interval corresponds to a latency of a destination of the reverse data transfer;

(d) when a new data transfer occurs between the mobile station and the destination before the selected inactivity timeout interval expires for the last data transfer, continuing from step (a), else

(e) releasing the channel resource allocated to the mobile station when the selected inactivity timeout interval expires.

12. The computer program of claim 11 wherein the long inactivity timer timeout interval is about one second and the short inactivity timer timeout interval is about 100 milliseconds.

13. The computer program of claim 11 wherein the last data transfer is a non-streaming data transfer.

15. The computer program of claim 11 wherein the last data transfer is sent to the mobile station.

17. The computer program of claim 12 wherein the destination is a server that sends a kill switch packet with acknowledgment required to the mobile station after the last data transfer to initiate rapid release of the channel resource.

18. The computer program of claim 11 wherein the channel resource comprises a radio link between the mobile station and the base station.

19. The computer program of claim 18 wherein the mobile communications network comprises one of Global Packet Radio Service, Global System Mobile, Code Division Multiple Access, Universal Mobile Telecommunications System, and other mobile communications systems that include mobile stations such as cellular telephones and wireless computer devices and equivalents thereof.

20. The computer program of claim 11 wherein the mobile station comprises one of a telephone and a computer device.

14. The computer program of claim 14 wherein the last data transfer comprises a TCP/IP data packet.

16. The computer program of claim 16 wherein the mobile station pings an Internet server after the last data transfer to initiate rapid release of the channel resource.
