Abstract

An embodiment of the present invention relates to a network management method for improving E911 services. The network management method including determining a location of at least one user in a communications network, creating a coverage map for the communications network based on the determined location of the at least one user in the communications network, and providing the coverage map to an emergency services database. Additionally, the coverage map includes information depicting at least one user in the communications network.

changing configuration parameters of the communication network;

updating the created coverage map for the communications network, said updating occurring after the configuration parameters of the communication network are changed;

providing the updated coverage map to the emergency services database; and

notifying the emergency services database to use the updated coverage map depicting the individual coverage of the one of the at least one user in the communications network for providing emergency services to the communications network.

7. The network management method of claim 6, wherein the changing of the configuration parameters of the communications network includes changing a basestation transmission power, an antenna tilt angle, a channel bandwidth, an antenna gain, an antenna beamwidth, or an antenna azimuth direction.

8. A network management method for providing E911 service comprising:

obtaining a coverage map for a communications network including information depicting at least one user in the communications network;

changing configuration parameters of a communication network;

updating the obtained coverage map for the communications network, said updating occurring after the configuration parameters of the communication network are changed;

providing the updated coverage map to an emergency services database; and

notifying the emergency services database to use the updated coverage map for providing emergency services to the communications network.

9. The network management method of claim 8,

wherein the coverage map for the communications network depicts a composite coverage of the at least one user in the communications network, and

wherein said changing the configuration parameters of the communications network includes changing a basestation transmission power, an antenna tilt angle, a channel bandwidth, an antenna gain, an antenna beamwidth, or an antenna azimuth direction.
