Wireless communication system for increasing the rescan timer in a wireless communication device
View Patent ↗Embodiments disclosed herein provide systems and methods for operating a home wireless communication network to facilitate increasing the rescan timer for a wireless communication device. In a particular embodiment, a method comprises determining a location of a wireless communication device that is roaming on a visited wireless network. The method further includes determining a communication load in a portion of the home wireless network that is proximate to the location of the roaming wireless communication device and processing the communication load to determine if a home network rescan timer in the wireless communication device should be increased. If the home network rescan timer in the wireless communication device should be increased, the method further comprises transferring a first message for delivery to the wireless communication device indicating an increase to the home network rescan timer.
1. A method of operating a home wireless communication network comprising:
determining a location of a wireless communication device that is roaming on a visited wireless network;
determining a communication load in a portion of the home wireless network that is proximate to the location of the roaming wireless communication device;
processing the communication load to determine whether a home network rescan timer in the wireless communication device should be increased; and
if the home network rescan timer in the wireless communication device should be increased, transferring a first message for delivery to the wireless communication device indicating an increase to the home network rescan timer.
2. The method of claim 1 wherein the first message comprises a text message.
3. The method of claim 1 wherein determining the location of the roaming wireless communication device comprises receiving an authorization request transferred by the visited wireless network.
4. The method of claim 3 wherein the authorization request indicates a base station in the visited wireless network that serves the roaming wireless communication device and wherein the base station indicates the location.
5. The method of claim 3 wherein the authorization request indicates a control system in the visited wireless network that serves the roaming wireless communication device and wherein the control system indicates the location.
6. The method of claim 1 wherein determining the location of the roaming wireless communication device comprises receiving a second message transferred by the roaming wireless communication device.
7. The method of claim 6 wherein the second message comprises a text message.
8. The method of claim 6 wherein the second message indicates a base station in the visited wireless network that serves the roaming wireless communication device and wherein the base station indicates the location.
9. The method of claim 6 wherein the second message indicates a control system in the visited wireless network that serves the roaming wireless communication device and wherein the control system indicates the location.
10. The method of claim 1 wherein the portion of the home wireless network proximate to the location of the roaming wireless communication device comprises a sector in the home wireless network that is adjacent to a base station in the visited wireless network that serves the roaming wireless communication device.
11. A control system on a home wireless communication network comprising:
a processing system configured to determine a location of a wireless communication device that is roaming on a visited wireless network, determine a communication load in a portion of the home wireless network that is proximate to the location of the roaming wireless communication device, and process the communication load to determine whether a home network rescan timer in the wireless communication device should be increased;
a communication interface configured to, if the home network rescan timer in the wireless communication device should be increased, transfer a first message for delivery to the wireless communication device indicating an increase to the home network rescan timer.
12. The control system of claim 11 wherein the first message comprises a text message.
13. The control system of claim 11 wherein the communication interface is further configured to receive an authorization request transferred by the visited wireless network and the processing system is configured to determine the location of the roaming wireless communication device based on the authorization request.
14. The control system of claim 13 wherein the authorization request indicates a base station in the visited wireless network that serves the roaming wireless communication device and wherein the base station indicates the location.
15. The control system of claim 13 wherein the authorization request indicates a control system in the visited wireless network that serves the roaming wireless communication device and wherein the control system indicates the location.
16. The control system of claim 11 wherein the communication interface is further configured to receive a second message transferred by the roaming wireless communication device and the processing system is configured to determine the location of the roaming wireless communication device based on the second message.
17. The control system of claim 16 wherein the second message comprises a text message.
18. The control system of claim 16 wherein the second message indicates a base station in the visited wireless network that serves the roaming wireless communication device and wherein the base station indicates the location.
19. The control system of claim 16 wherein the second message indicates a control system in the visited wireless network that serves the roaming wireless communication device and wherein the control system indicates the location.
20. The control system of claim 11 wherein the portion of the home wireless network proximate to the location of the roaming wireless communication device comprises a sector in the home wireless network that is adjacent to a base station in the visited wireless network that serves the roaming wireless communication device.
