Abstract

The present invention provides a system and method for managing localized, event-generated overload of a communication network. A first step (400) includes receiving input indicative of a status change of an event in a sports stadium. A next step (402) includes generating an output to the communication network indicating that loading of the communication could be increasing in response to the status change. A next step (404) includes predicting an increased load due to the status change and comparing (406) this against a threshold. A next step (408) includes modifying the services available in geographic proximity to the event for a predetermined period in order to accommodate the increased load due to the status change.

Claims

1. A method for managing localized event generated overload of a communication network, the method comprising the steps of:

receiving input indicating a status change of an event;

generating an output to the communication network indicating that loading of the communication will be increasing in response to the status change; and

modifying the services available in geographic proximity to the event in order to accommodate an increased load due to the status change.

2. The method of claim 1, further comprising the steps of:

inputting actual loading information resulting from the status change from the communication network; and

using the actual loading information in predictions for loading.

3. The method of claim 1, wherein the receiving step includes an event in a sports stadium.

4. The method of claim 3, wherein the input of the receiving step includes one of the group of;

a change in score, a change in player position(s), a time out, a change of possession, and an increased noise level.

5. The method of claim 1, wherein the input also indicates that there will be an upcoming status change of the event.

6. The method of claim 1, wherein the modifying step reduces a bit rate for new calls for a predetermined period.

7. The method of claim 1, wherein the modifying step bars higher bit rate services and allows lower bit rate services for new calls for a predetermined period.

8. The method of claim 1, wherein the modifying step includes warning a user about an upcoming change in service availability before the user can place a call.

9. The method of claim 1, wherein the modifying step includes reducing network access for lower priority service and increasing network access for higher priority service for a predetermined period.

10. The method of claim 1, wherein the modifying step includes reconfiguring voice channels for text messaging for a predetermined period.

11. A method for managing localized event generated overload of a communication network, the method comprising the steps of:

receiving input indicative of a status change of an event in a sports stadium;

generating an output to the communication network indicating that loading of the communication could be increasing in response to the status change;

comparing a predicted increased load due to the status change against a threshold; and

modifying the services available in proximity to the stadium for a predetermined period in order to accommodate the increased load due to the status change.

12. The method of claim 11, further comprising the steps of:

inputting actual loading information resulting from the status change from the communication network; and

using the actual loading information in predictions for loading.

13. The method of claim 11, wherein the modifying step reduces a vocoder bit rate for new calls for the predetermined period.

14. The method of claim 11, wherein the modifying step bars higher bit rate services and allows lower bit rate services for new calls for the predetermined period.

15. The method of claim 11, wherein the modifying step includes warning a user about service availability before the user can place a call.

16. The method of claim 11, wherein the modifying step includes reducing lower priority service and increasing higher priority service for the predetermined period.

17. The method of claim 11, wherein the modifying step includes reconfiguring voice channels for text messaging for the predetermined period.

18. The method of claim 11, wherein the modifying step includes handing off calls to cells neighboring the stadium for at least the predetermined period.

19. The method of claim 11, wherein the comparing step includes dynamically changing the threshold to accommodate changing call demand.

20. A system for managing localized event generated overload of a communication network, the system comprising:

an event monitor operable to receive input indicating a status change of an event and generate an output to the communication network indicating that loading of the communication will be increasing in response to the status change; and

at least one base station servicing the area of the event, the at least one base station operable to modify the services available in proximity to the event in order to accommodate an increased load due to the status change.
