Abstract

Network entity, method and computer-readable storage medium for use in a network that includes an arrangement of cell sites, each cell site being configured to provide wireless services to users within a respective coverage region. The network entity comprises an input configured to receive position information regarding occurrence of an event at an event site, and a processing entity configured to determine on a basis of the position information regarding occurrence of the event and policy information regarding the network, whether the event warrants coverage region reconfiguration and, if so, to generate a message commanding an adjustment to the coverage region of at least one cell site. An output is configured to release the message towards the at least one cell site, whereby application of the adjustment to the coverage region of the at least one cell site enables an increase in traffic to be accommodated in a vicinity of the event site.

4. The network entity defined in claim 3, wherein said message commanding an adjustment to at least one of the size, shape and position of the respective coverage region comprises an indication of an adjusted size, shape or position of the respective coverage region.

5. The network entity defined in claim 1, each coverage region being a function of antenna response characteristics for the respective cell site, wherein said message commanding an adjustment to the coverage region of at least one of said cell sites comprises a message commanding an adjustment to the antenna response characteristics for the respective cell site.

6. The network entity defined in claim 5, wherein said message commanding an adjustment to the antenna response characteristics for the respective cell site comprises an indication of adjusted antenna response characteristics.

7. The network entity defined in claim 1, wherein said second message comprises action requests.

8. The network entity defined in claim 1, wherein said second message comprises driving directions to the event site.

9. The network entity defined in claim 1, whereby application of said adjustment to the coverage region of said at least one of said cell sites enables an increase in traffic to be accommodated in a vicinity of said event site.

10. The network entity defined in claim 1, whereby application of said adjustment to the coverage region of said at least one of said cell sites causes a first one of said plurality of said cell sites to take over wirelessly servicing a subset of users previously serviced by a second one of said plurality of said cell sites, said first one of said plurality of said cell sites being more distant from the event than said second one of said plurality of said cell sites.

11. The network entity defined in claim 1, wherein the first message commanding an adjustment to the coverage region of at least one of said cell sites comprises a message commanding a series of consecutive adjustments to the coverage region of the at least one of said cell sites.

12. The network entity defined in claim 1, wherein the network IS a public network.

13. The network entity defined in claim 1, wherein the network is an emergency services network.

14. The network entity defined in claim 1, the output being configured to release said message towards said at least one of said cell sites via a configuration entity in the network.

15. The network entity defined in claim 14, the processing entity being further configured to generate enhanced data in response to receipt from the configuration entity of a confirmation that said adjustment to the coverage region of said at least one of said cell sites has been applied, the output being further configured to release said enhanced data towards at least one external entity.

16. The network entity defined in claim 15, wherein said enhanced data comprises an authorization to transmit multimedia content to and from users in the vicinity of the event.

17. The network entity defined in claim 1, wherein the vicinity of the event is time-varying.

18. The network entity defined in claim 1, wherein the vicinity of the event comprises a geographic corridor leading to and from the event site.

19. A method in a network that includes an arrangement of cell sites, each cell site being configured to provide wireless services to users within a respective coverage region, the method comprising:

receiving position information regarding occurrence of an event at an event site and information regarding a nature of the event;

determining based, at least in part, on the position information regarding occurrence of the event and the information regarding the nature of the event, whether the event is sufficiently critical to require an emergency response and, if so, to generate a first message commanding an adjustment to the coverage region of at least one of said cell sites and a second message commanding a response from an emergency response agency; and

releasing the first message towards said at least one of said cell sites and said second message towards the emergency response agency.

20. The method of claim 19, wherein the emergency response agency is at least one of a fire department, a police unit, an ambulance, a hazardous materials unit, the Army/National Guard and a containment unit.

21. The method of claim 19, each coverage region having a size, shape and position, wherein said first message commanding an adjustment to the coverage region of at least one of said cell sites comprises a message commanding an adjustment to at least one of the size, shape and position of the respective coverage region.

22. The method of claim 21, wherein said message commanding an adjustment to at least one of the size, shape and position of the respective coverage region comprises an indication of an adjusted size, shape or position of the respective coverage region.
